Parking Space Guidance and Three-dimensional Parking System Help the Development of Intelligent Park

It is used to display the idle status of this group of parking spaces in the parking lot system. Only when the group of parking spaces are full of vehicles, each group of parking spaces shall be equipped with a parking space indicator. The parking space indicator will be displayed in red. Brewing from the end of last century, the emergence of intelligent parking industry of Huicong intelligent community Netcom is inseparable from the process of rural development in China. From the beginning of this century to the increasing popularity of today, it took only a few decades for science and technology to push through the old and bring forth the new, quietly changing people's lives from time to time.

A variety of existing parking technologies carry out professional intelligent work around vehicle parking, and parking space guidance has become one of the important technologies of intelligent parking. With the development of rural intelligent parking technology, the advantages of three-dimensional garage are prominent, and the development is particularly eye-catching. An indication system that enables the vehicle to enter the destination parking space smoothly. It is generally used in parking lots. The parking space guidance system is mainly used to guide vehicles that need to park.

It is convenient for parking, makes the parking lot management standardized and orderly, and is a powerful supplement to the intelligent parking lot system. Its working principle is as follows: firstly, an ultrasonic detector is installed on each parking space, and then the ultrasonic detection technology is used to detect the parking space. It can detect whether the parking space is idle, send the data to the disposal center, output through the disposal center, and feed back the information to each indication display. The parking space guidance system consists of three parts, as follows. the data acquisition system connects the probe to the probe controller through RS485 bus, and the parking space guidance system installs an ultrasonic probe directly above each parking space. The probe controller summarizes and disposes the collected information, and then connects it to the acquisition terminal through an RS485 bus.

The acquisition terminal transmits each parking space information to the data processing center through the CAN bus. The data center transmits the data to the management computer in real time, and the computer analyzes and disposes of the data. Here, the data center can also transmit the data to the acquisition terminal, which can send the information to the empty parking space display screen for parking guidance. the central processing system and transmits it to the corresponding display equipment. The central processing is mainly to analyze the collected data. It mainly includes the following aspects; Use the management computer to release relevant data to the LAN; Data can be transmitted to the control center of rural parking guidance system through GSM wireless modem.

Publish the parking space data in the parking lot. the output display system constitutes the transmission display system. The information collected by the central processing system is analyzed and processed. What I rarely see in this part is the display screen and guide license plate. Send it to each display screen to display parking space information for parking guidance. Current situation: the development of rural parking guidance system, Europe, America and other countries have carried out a lot of research work.

Rural parking guidance system is an important part of it intelligent transportation system. It has been applied to the city center. The United States, Germany and other transportation developed countries have promoted it in more than a dozen cities. By using the parking guidance system, it has greatly alleviated the rural traffic congestion, reduced the road occupation, reduced the vehicle exhaust emission and noise, significantly improved the utilization rate of the original parking facilities, and achieved good social and economic benefits. There are similar demonstration projects in China, such as Beijing, Shanghai and Guangzhou, and some results have been achieved, but the technical means and the content expression form of induction display are different.

Through the development in recent years, various software and hardware technologies of rural parking guidance system have been immature. The parking lot system has laid a good foundation for the promotion and implementation of the system: the development of wireless communication technology, especially mobile communication technology, provides great convenience for the construction of rural traffic information. Many international famous communication companies, such as GSM mobile communication network, have developed data communication products. LED technology is more and more used in many industries to provide users with all kinds of information because it can work all day and continuously and has good display effect. At present, the products of domestic companies have been improved in display effect, interface technology and operation stability than before.

GI technology can easily realize the combination and matching of data and geographic information. Now it has been widely used in the development of various geographic information systems. It makes a comprehensive analysis of the database to form a topic oriented conclusion, and the application category of data warehouse and data mining technology. Although there is no good specific application at present, this is the development trend and application direction of data processing. The number of private cars in China has exceeded 26 million.Due to the lack of parking lot planning in cities in the early years, by the end of 2009. The popularity of cars makes parking spaces nervous. The construction of three-dimensional garage is favored by major cities because it can save space. Three-dimensional garage has also become a future trend of parking lot development. For the three-dimensional garage, the lifting and transverse three-dimensional garage is widely used in China. Because the parking environment is more complex, a group of parking spaces are generally multi-storey structure.It is difficult for car owners to intuitively find empty parking spaces after entering the three-dimensional garage. They often find that there are free parking spaces on the reorganized parking spaces after the vehicles are driving, which not only consumes parking time, but also easily leads to scratches between different vehicles. The empty parking space in the current direction is displayed. The parking space guidance system uses the LED parking space display installed at the entrance of the garage and at the entrance of each internal channel. To guide the owner to select the parking channel.

The side of each group of parking spaces in the garage near the channel is equipped with parking space indicator lights to display the idle status of the reorganized parking spaces. When a group of parking spaces are full, the parking space indicator will display red. If there are free parking spaces in this group, the indicator will display green. The steel tray is often displaced, and the parking space of the three-dimensional garage is relatively unstable. The conservative parking system will inevitably interfere with the parking space detector.
