Figure 1 Schematic diagram of parking management systemThe controller design block diagram is shown in Figure 2. The system selects SPCE061A single chip microcomputer as the main control chip. The single chip microcomputer detects the arrival of the vehicle through the level change of card reading signal and phase-locked loop circuit. The DS1302 clock circuit provides the system with accurate time information, and displays the parking space and time information in real time by driving the LED display board. The system has a serial communication interface with the upper computer.Figure 2 overall design block diagram of vehicle detection system in intelligent parking lot
3. Introduction to system principle 3.1 vehicle detection Accurate vehicle detection is the prerequisite for the normal operation of the system. Through the comparison of various schemes, the vehicle detector of this design adopts the ground induction coil detection scheme. Ground induction coil vehicle detector is a vehicle detector based on the principle of electromagnetic induction. The ground induction coil ll is buried under the road surface and a ring coil with a certain working current is wound by multi turn conductors and buried in the road. The coupling circuit composed of ground induction coil is shown in Figure 3:
Fig. 3 coupled oscillation circuit
T is the isolation transformer, the turns ratio is 1:1, the triode UL and U2 form a common emitter oscillator, and the resistance R3 is the common emitter resistance of the two triodes and forms positive feedback. As an inductive element in the detector resonance circuit, the ground induction coil forms L C resonance together with the oscillation circuit of the vehicle detector. When a vehicle passes through, the magnetic flux generated by the unit current in the coil will increase, resulting in a slight change in the coil inductance value, and then change the frequency of LC resonance. This change in frequency is used as the input signal of the vehicle passing through the ground induction coil. In order to detect this change, the common method is to calculate the number of oscillation pulses per unit time by single chip microcomputer to determine whether the car is coming. In this design, it is necessary to detect the frequency change of two ground induction coils. If the single chip microcomputer is used to measure the frequency change of two signals at the same time, the system is relatively large and the program is complex, which makes the single chip microcomputer bear a heavy burden. A new detection method is introduced here: the PLL audio decoder LM567 is used to detect the change of frequency. The application circuit diagram is shown in Figure 4:
Fig. 4 PLL circuitThe external resistance and capacitance of pins 5 and 6 of LM567 determine the center frequency of VCO in IC, fo = 1 / 1.1rc. Pin 1 and pin 2 are usually connected to the ground to form an output filter network and a loop low-pass filter network. The capacitance connected to pin 2 determines the capture bandwidth of the PLL circuit. The theoretical value of the bandwidth can be calculated by this formula:
When the audio decoder LM567 works, if the input signal frequency falls within the given passband, the PLL will lock the signal. At the same time, the internal transistor of LM567 is controlled on, and pin 8 outputs low level, otherwise it outputs high level. When the input signal frequency is within the passband, the LM567 locks and outputs a low level. Generally, when there is no vehicle, the oscillation frequency of the coupling circuit will remain unchanged within a certain range. When the vehicle passes through the ground induction coil, the oscillation frequency of the coupling circuit will change. Moreover, with the different vehicle models and the uneven iron quality of the vehicle itself, the change of this frequency will also float within a certain range. Therefore, through the experiment, select the appropriate LM567 capture bandwidth value, so that when there is no vehicle, although the input signal frequency changes slightly, the floating frequency is within the passband, the LM567 is locked, and the 8-pin output low level; When a car arrives, the frequency changes dramatically and is no longer in the passband, and pin 8 will output high level. At this time, the detection of whether the vehicle is coming is transformed into the detection of the level. The arrival of the vehicle can be sensed by triggering the external interrupt of the single chip microcomputer, and there is no need to distinguish whether the frequency change at this time is caused by the arrival of the vehicle through a complex program, which greatly reduces the difficulty of programming. 3.2 other control parts Controlling the rise and fall of the brake rod machine is to control the forward and reverse of the DC motor of the brake rod machine. The high and low levels are output through the single chip microcomputer control port to cooperate with the relay. The forward and reverse can be realized by adding positive and reverse voltages at both ends of the DC motor. For time recording, DS1302 calendar chip is selected here. DS1302 can record the year, month, day, week, hour, minute and second. It can be connected to the backup power supply and can always work continuously when the main power supply is turned off. The single chip microcomputer SPCE061A can read the current time at any time. The communication with the host computer uses the universal asynchronous serial communication module (UART) of SPCE061A, which provides a full duplex standard interface. With the help of the special function of iob port and UART IRQ interrupt, it realizes the com link with the RS-232 serial communication interface configured by the host computer, and realizes the timely transmission of data. In addition, the voice prompt part makes use of the voice processing advantages of SPCE061A. Using SPCE061A voice compression algorithm library and built-in DAC, clear voice broadcasting function can be realized without adding voice chip. 4. Main software design of the system The main program of the system is mainly responsible for system initialization (including the initialization of each IO port, interrupt initialization and DS1302 initialization), and the time display of LED display board. Using the 0.5s time base interrupt of SPCE061A, read the time information of DS1302 every 0.5s and refresh the LED display. The detection of card reading information and vehicle information of ground induction coil adopts the form of external interrupt trigger, and various automatic controls are realized in the interrupt service program. The program flow of the main interrupt service program is shown in figures 5 and 6:
Fig. 5 flow chart of card reading interrupt service program Fig. 6 ground induction coil interrupt service program
This design uses SPCE061A to realize the automatic detection of vehicles in and out of the parking lot, the automatic take-off and landing of the brake rod machine and the real-time display of parking space information. With the IC card information processing and image processing system, the automatic management of the intelligent parking lot can be realized. The application of ground induction coil makes the vehicle detection accurate and ensures the reliability of the system. reference: Luo Feiya, Lingyang 16 bit MCU application foundation, Beijing: Beijing University of Aeronautics and Astronautics Press, 2005 Zhao Hailan.

With the continuous rise of living consumption level, the number of cars also shows a rapid upward trend, and many problems have been exposed in the traditional parking lot system.I believe many people have this experience, that is, when parking in some traditional parking lots, the parking charge is slow and inefficient, which often leads to vehicle congestion and slow traffic at the entrance and exit of the parking lot, and the charging situation of the parking lot is also full of loopholes. For example, the parking lot administrator will transfer the parking ticket and enrich the parking fee. Assuming that parking for 30 minutes is free, the charge is 5 yuan an hour, and each parking ticket can be worth one hour. Owner a still gives the parking ticket to the administrator during the free period when he leaves the site. The administrator does not need to hand in the parking ticket. When owner B leaves the site without a parking ticket, he will give the administrator 5 yuan for one hour. The administrator will get 5 yuan from handing in a's parking ticket, which will directly affect the economic benefits of the parking lot.With the continuous development of Internet technology, the urgent need to solve the loopholes of parking lot system promotes the birth of intelligent parking lot management system. The vehicle identification software will automatically and strictly record the entry and exit records of any vehicle into the system. Even if the security guard manually opens the gate to release the vehicle without permission, the system will still produce corresponding billing behavior, so as to make all accounts in and out of the vehicle clear, transparent and evidence-based. The real-time QR code parking ticket is adopted to replace the paper parking ticket. The owner directly pays online self-service fees, and the merchant defines the refresh time to eliminate any cheating. Through various technical means, this set of road gate vehicle identification system of one billion partners makes the parking charge truly watertight and increases the income of the park to the greatest extent.
With the progress of science and technology and the development of human civilization, people have higher and higher requirements for parking lots. Intelligent parking lot management system came into being. Now more and more communities have installed intelligent parking lot management system, which not only has a higher and higher degree of intelligence, but also brings convenience and happiness to people's life and improves efficiency. Intelligent parking lot system has irreplaceable advantages in community vehicle management, mainly reflected in the following aspects.1. Rigorous charging and blocking charging loopholes. The intelligent parking lot system adopts computer billing and charging, and each payment is recorded in the system. The charging is accurate. At the same time, it also has a variety of means to block the charging loopholes, avoid cash loss and ensure the income of the parking lot.2. Multiple charging methods to flexibly meet various management needs. The intelligent parking lot system has a flexible payment method, which can easily meet the needs of different users, such as temporary users, fixed users, special users, monthly rent users, etc. These can be set in the system to meet different management needs.3. Improve safety precautions to prevent vehicles from being stolen. The intelligent parking lot system is equipped with surveillance cameras to automatically capture and compare incoming and outgoing vehicles, effectively prevent vehicles from being stolen, and provide a good guarantee for vehicles in the community.4. The system is user-friendly and easy to operate and manage. Moreover, the parking lot equipment is equipped with computer voice prompt, help intercom, highlighted led Chinese and English, digital display screen, automatic parking space statistics, full space prompt, etc., which is convenient for users.5. High degree of automation, reduce staff work intensity and improve management efficiency. The intelligent parking lot management system adopts a variety of advanced technologies, such as smart card technology, Bluetooth technology, license plate recognition technology, etc., which can realize the unmanned management of the entrance, improve the management efficiency and reduce the labor cost.
With the increasing attention paid to the parking problem, at present, the residential areas in many cities have almost installed the intelligent parking lot system. This system can not only efficiently save the parking time of car owners, but also save many management problems for property management. However, what are the maintenance matters of the intelligent parking lot system? Let's take a look with the Xiaobian of Baibai safety net!Intelligent parking lot system maintenance1 The gate moves up and down or often turns its head1. Check CPU;2. Check the limit switch;3. Check the power-off switch;4. Check the limit switch;2 The LED of the display is not displayed1. Check whether the LED power supply is normal;2. Check whether the LED chip is normal1. Check the voice chip;2. Check potentiometer;4 License plate recognition: the recorded license plate cannot be recognized.1. Unclear image shootingThe difficulty of license plate location mainly comes from the collected images. Due to the diversity of the collected license plate images, and the collection of images is affected by many factors, such as rainy days, heavy fog, light, etc. in this case, the recognition results can achieve satisfactory results only when the image focus is clear. Then there are certain requirements for the photosensitive parts of the parking lot system. The video camera should be improved to see if the video settings are abnormal (normal settings), and the display resolution, color and desktop size should be adjusted.2. License plate damaged or stainedIn the practical application process of roads and cities, it is difficult to ensure that the license plates involved are free from contamination. After several years of use, the license plates will inevitably be polluted and worn. For this situation, many intelligent parking lot systems have gradually solved this problem, but if it is too serious, it still depends on manpower.5 Entrance controller: when the vehicle is pressed into the sensing area, the call key and ticket key lights are not on, and there is no voice prompt.1. Whether the sensor senses;2. Check whether the single chip microcomputer is working;3. Check whether there is a problem with the wiring of ticket lamp.4. Check whether there is a problem with the lotus root;6 The gate does not open: the gate does not open if the license plate recognition passes.1. Check whether the switch opening terminal is firmly connected;3. If the gate still cannot be opened, check whether the gate crashes;2. Check whether there is switch signal output at the gate opening terminal. If not, the gate control relay is broken, and replace the control board of the controller.The above is the answer to the maintenance of intelligent parking lot system provided by Baibai safety net Xiaobian.

The Future Intelligent Parking Lot Management System Needs Customized Parking Scheme - Tigerwong Tec
The security industry has always given people an image of safety and protection since its birth, but it is not. The current security industry includes too many contents, and the parking lot industry is one of them. In recent years, the domestic parking problem has always been the second big problem after the house price. The price of cars has fallen. Many people have private cars, so the problem of parking comes out.The car parking management system on the market combines the advanced experience at home and abroad, integrates big data, cloud computing and other technologies, and generally meets the needs of a considerable number of people, but is the future trend consistent or different? Next, let's study with tigerwong parking system. At present, the parking industry is the most concerned industry in the field of intelligent transportation. How to make it more convenient for users to park and more convenient for parking lot management is a problem that should be considered by the manufacturer of parking lot system. Although some standardized functions can meet the general parking lot management and people's parking needs, with the increasing number of vehicles, There will still be some problems. Then, the future intelligent car parking management system must have a professional customized parking scheme in order to completely solve people's parking problems.I. intelligent parking management system scheme of group property with the acceleration of China's urbanization and rapid economic development, many property companies have developed into group property companies all over the country, and the number of parking lots managed has increased from a few to hundreds or even thousands, Parking fees also account for an increasing proportion of property management income. How to manage these parking lots uniformly, reduce management costs and increase management income is an urgent problem for property companies. Application scenario: the group property company needs to manage thousands of properties and their parking lots. Its organizational structure is often a multi-level pyramid structure. There are different claims at each level.It can be managed by region and region, and the grading standard can be customized. The grading management can not affect the daily operation of the parking lot. II. Intelligent parking management system for commercial complex the central business district is characterized by dense population and large traffic flow, which often leads to road traffic congestion in the region due to too many vehicles. Therefore, effectively managing vehicles and reducing congestion is one of the important problems to be solved. While solving vehicle congestion, how to effectively reduce management and operation and maintenance costs is also an urgent problem to be considered.In the face of consumers' self driving into the commercial center for shopping, how can the commercial center realize a series of functions such as guiding consumers to park their vehicles in the mall, querying the parking location, shopping parking concessions, self-service payment and so on? Application scenario: various hardware wholesale cities, cloth market, clothing wholesale city, CBD Central area integrating business, leisure, office and other functions, or commercial areas led by some large supermarkets. The scale of these commercial center parking lots is large, and there are usually hundreds or even thousands of parking spaces. III. The intelligent parking management system scheme for large and medium-sized parking lots has a small number of parking spaces and a large number of owners' vehicles. In order to avoid disputes, the property cannot sell monthly tickets without restrictions; As a result, most vehicles have to pay parking fees before leaving the site every day, and the payment queue leads to slow traffic and road congestion; In addition, in the morning and evening peak hours, the traffic flow is large, the access is slow, and the long queue of vehicles is also easy to form congestion. Owners who own more than one car but buy only one parking space often have disputes with the property because of whether they pay more or less parking fees.In order to strengthen the management, the property often registers and manages the vehicles entering the community, but the owners who do not buy monthly tickets often feel that they have not been investigated and respected by the property personnel. Application scenario: in modern cities, hospitals, schools, buildings, communities with more than 1000 residents and other places are places where people gather. The supporting parking lots of these places are generally large and medium-sized parking lots, the number of parking spaces is usually hundreds or more, and the design places of vehicle entrances and exits are often more in and out. Most of the vehicles to and from these places are temporarily parked for business, and the parking fee will be paid before leaving after the work is completed. IV. intelligent parking management system scheme for small and medium-sized parking lots for some communities, the number of parking spaces in the parking lot is small and the owner has many vehicles.In order to avoid disputes, the property cannot sell monthly tickets without restrictions; As a result, most vehicles have to pay parking fees before leaving the site every day, and the payment queue leads to slow traffic and road congestion; In addition, in the morning and evening peak hours, the traffic flow is large, the access is slow, and the long queue of vehicles is also easy to form congestion. Application scenario: in a residential area with offices, enterprises and institutions and households of about 1000 people, there are usually about 300 parking spaces in the parking lot or more. The entrance and exit of the parking lot is usually within two in and two out. V. when the roadside parking handheld charging application scheme vehicle enters the management area, the administrator captures the parking space photos in real time through the handheld machine, identifies the license plate number and starts timing; When the vehicle leaves the parking lot, the license plate shall be captured by mobile phone for charging, and the parking management fee shall be charged by the administrator. The vehicle occupancy detection system transmits the parking space data to the cloud platform in real time for data analysis.It is necessary to manage the charging of roadside parking spaces according to time, and conduct real-time statistical analysis on whether there are cars in the parking spaces, so as to facilitate the supervision of charging. Application scenario: in some cities with heavy traffic, roadside parking can be set on the road where not many vehicles pass by. Due to the small number of parking spaces, parking spaces have been set aside in many parts of the city, especially on the roadside, so as to facilitate citizens to park. These parking spaces are subject to time charging management. Intelligent parking management system uses the Internet to manage big data of all parking lots, breaks through the information island of single parking lot operation management, and realizes a comprehensive information management platform integrating information collection, equipment management, personnel management, vehicle management, parking space management and financial management, The car parking management system can be customized one-to-one.In the future, the diversification of parking lots can better solve the parking problem, and the car parking management system will be the only customization.

The Development of Intelligent Parking Lot Is Not Only Technology, but also the Selection of Appropr
Nowadays, domestic parking lots are developing towards intelligence. Many motorists feel that they don't stop at the intelligent parking lot and don't keep up with the times. Therefore, many parking properties want to develop intelligent parking lots. However, the property generally believes that as long as the development of parking technology is OK, in fact, it is not. It is also very important to choose a suitable parking lot floor.The following is our comparison of the performance of several main floors: first, epoxy floor epoxy floor technology refers to coating epoxy resin coating on the solidified cement floor with a coating thickness of about 1-5mm to form a closed organic protective layer. Because epoxy resin is an organic substance, this protective layer has good chemical characteristics such as water resistance, oil resistance, acid and alkali resistance, salt spray corrosion resistance, flat and seamless, easy to clean and maintain. It is a long-term floor material widely used in modern industry, and is widely used in medicine, food (aseptic production), electronics, chemical industry (anti-static) and other industries. However, the organic protective layer has several fatal weaknesses: 1. Hardness and wear resistance: organic materials cannot be comparable with inorganic materials in physical properties, and the Mohs hardness of the hardest resin is 2-3. In production workshops, parking garages, manufacturing and other places, due to the heavy mobile load and frequent use, such as cars, forklifts and mobile trolleys, the epoxy resin floor is often seriously scratched, resulting in shell lifting and falling off. 2. Service life: organic materials are high molecular polymers, which means that under normal conditions such as radiation, light and temperature, the polymer chain will break, which is often called aging! The service life of the best epoxy resin material (epoxy self leveling) can reach 5-8 years, and the service life of general industrial epoxy floor is about 3 years. II. The of wear-resistant floor and hard floor technology refers to that it is made by mixing carborundum or other aggregates into cement or concrete casting and solidification as a whole.The thickness of hardening layer is about 3-10mm. Due to the extremely high hardness of aggregates such as emery, the Mohs hardness of the hard floor is 6-7. There is basically nothing in common substances that can scratch its surface. Therefore, the hard floor is hard, wear-resistant, flat and seamless. In addition to being used as the floor of industrial plants, it can also be used as the floor of warehouses, garages, squares and other auxiliary facilities. However, the ground generated by this technology is made by bonding carborundum with cement as adhesive, so it also has the characteristics of cement products - a large number of pores left after water evaporation are bound to form on the surface.These pores have two negative effects on the ground effect: 1. Diffuse reflection on light and greatly reduce the gloss. If it is not waxed for maintenance, There is no good visual effect. 2. Absorbing sewage and dust is not conducive to creating a clean production environment and is not suitable for application in pharmaceutical and other industries. 3. With the passage of time, the surface weathering of cement products occurs, resulting in dust and sand. The general service life is 5-8 years, and the short service life is 2-3 years. III. terrazzo floor terrazzo is a kind of cement artificial stone. It has the advantages of low price, good overall performance and controllable shape and color.Therefore, it is widely used as ground material for public buildings and production workshops. However, due to wear and stain infiltration and other reasons, its surface is quickly weathered, stripped and polluted, losing its due architectural process characteristics. The main means of maintaining the terrazzo ground is daily cleaning, waxing and polishing.
