Detailed Explanation of a Set of Parking Lot Intelligent Management Control System Scheme

The parking lot charging management system uses highly automated electromechanical and microcomputer equipment to manage the parking lot safely and effectively, including charging, security, monitoring, anti-theft, etc. This system is specially designed for the automatic identification and billing of motor vehicles in the parking lot of high-grade commercial and residential buildings, high-grade office buildings, high-grade apartments and hotels. It is a new security management system that combines reading sensing identification technology, large-scale integration technology and computer technology. It uses reading sensing technology to automatically telemetry and identify cardholder drivers. Through the cooperation of car stop and special software technology, it provides automatic means and commercial supervision for security and billing management of parking lot. The system technology, simple operation, high reliability and confidentiality, is a more modern vehicle intelligent management and control system.

According to different objects, parking lots can be divided into internal parking lots and public parking lots.

The internal parking lot is mainly for fixed car owners. It is generally used for self-use parking lot of each unit, supporting parking lot of apartments and residential quarters, underground garage of office buildings and office buildings, etc. This kind of parking lot is characterized by fixed users and no external vehicles. Users use the facilities for a long time, have strict requirements on the safety of parking lot management, have high access density during rush hours, and have high requirements on the reliability and processing speed of parking lot equipment.

The public parking lot mainly provides services for temporary individual passengers, which can be charged or free. This kind of parking lot is common in large public places, such as stations, airports, stadiums and other places. The users of parking facilities are usually temporary one-time users, with a large number and short time. It is required that the depot management system has the advantages of low operation cost, simple use, firm and reliable equipment, and can meet the requirements of commercial processing such as charging. In view of the above characteristics, the parking lot management system is designed for a comprehensive parking lot with both internal vehicles and temporary toll vehicles. The design of the system has modular function. In this way, for specific projects, the scheme selection can be based on the grade of buildings, the number of vehicles, the number of garage entrances and exits, the nature of the garage, the ratio of fixed vehicles to temporary vehicles Considering the increase or decrease of each subsystem, it is flexible and convenient.

Non contact remote control identification: the system provides non-contact remote control identification. Different identification distances are provided according to different specifications of the reader. Ordinary readers can provide a reading distance of 10cm and special readers can provide a reading distance of more than 50cm.

Fast recognition speed: the reading response time can reach 94ms.

High reliability and easy installation: the reader is fully enclosed design with high sealing rate, which meets the international IP65 standard and is very difficult to forge. The contactless smart card is composed of integrated chips and is a passive card. The system is completely electronic, the equipment occupies a small area and is not easy to be damaged, so it can be constructed in the later stage.

Easy and fast to use: it can be automatically calibrated according to the changing environment, and the signal sent by the sensor can be read and sensed through non-metallic objects.

The system is flexible and open: the system can be flexibly connected with other equipment to control such as doors, gates, lights, alarms or cameras. The system software can be easily changed according to user requirements, and can also be connected to the building network.

Perfect background management: the powerful background management system can comprehensively track the use of each card issued and the access of each vehicle. Chinese interface, easy to understand and learn, can automatically charge and generate statistical reports.

Audible and visual alarm.

3 Main functions of the system

1. The system divides users into two types: fixed users and temporary users. Fixed users pay in advance (one month, three months, six months or one year), and no charge will be charged for each appearance. When temporary users leave the site, they will pay once according to the parking time and current rate.

2. All vehicles enter by card, and all data such as card reading time, place and vehicle are automatically displayed and recorded on the computer.

3. After all vehicles swipe their cards, they will leave the site after being charged by the toll collector (temporary user) or confirmed (fixed user).

4. The traffic time and alarm time can be set arbitrarily. In case of special circumstances, it can also be set and programmed regularly.

5. The system has hierarchical management function, and the personnel operating the system have records.

6. Detailed card management functions.

7. The above functions are automatically recorded by the computer, and the access report, card report and alarm report can be printed.

8. The ground induction coil technology adopted by the system controls the falling of the car stop arm. The ground induction coil is installed at the electric car stop arm. When the vehicle enters the card reading range, the driver reads the card, and the system determines whether it is valid or invalid. When it is valid, the electric car stop arm is lifted. When the vehicle enters the induction range of the ground induction coil, the ground induction coil determines whether the vehicle has driven past (within the effective range). If the vehicle fails to pass, the electric car stop arm does not fall, and after the vehicle passes (within the effective range), the electric stop arm will fall down to complete this task. If a vehicle follows in, the ground induction coil will output a signal to keep the electric stop arm from falling. The stop bar will fall only when the vehicle passes through the entrance and exit and passes a predetermined safe distance, so as to ensure the safe passage of the vehicle.

1. Mobilization process:

When the vehicle drives to the entrance of the parking lot, the ground sensing coil detects the vehicle, transmits the signal to the entrance ticket box through the ground sensing, the system voice prompts "please swipe or read the card", the driver presses the button to pick up the card (the monthly rent card driver directly shakes the monthly rent card in the sensing area), and hears "tick" When the card reading is successful, the system will transmit the received card reading information to the control host. The control host records the entry time of the vehicle and the temporary card number (monthly rent card automatic check data), and sends a release signal to the gate. The gate rises, the driver drives in, the induction coil detects that the vehicle has entered, and the gate closes automatically.

2. Exit process

a. Monthly rental trucks:

When the vehicle drives to the exit of the parking lot, the ground sensing coil detects the vehicle and transmits the signal to the exit ticket box through the ground sensing. The system voice prompts "please read the card". The driver directly shakes the monthly rent card in the sensing area and hears "tick" The system transmits the received card reading information to the control host and sends a release signal to the gate. The gate rises, the driver drives out, the induction coil detects that the vehicle has entered, and the gate closes automatically.

b. Temporary card vehicle:

When the vehicle drives to the exit of the parking lot, the ground induction coil detects the vehicle, transmits the signal to the exit ticket box through the ground induction, and the system voice prompts "please read the card" , the driver directly gives the temporary card to the staff in the sentry box. The staff reads the card on the exit card reader and makes a correct judgment. The staff swipes the card on the card reader for release, the exit gate rises, the driver drives away, the induction coil detects that the vehicle has entered, and the gate closes automatically.
