The parking guidance system consists of three parts: data acquisition system, central processing system, and output display system.
data collection system
1 Install an ultrasonic probe directly above each parking space (the ultrasonic probe address can be set according to the site conditions, starting from the 1st order in order, gradually increasing), 8 ultrasonic probes connected to a probe controller through the RS485 bus; (also Can be transmitted via wireless radio frequency)
2 The probe controller collects and processes the collected parking space status information through the RS485 bus, and then connects to the collection terminal through another RS485 bus. The probe controller can also control the parking lights and parking status lights according to the collected parking space information. Up to 16 probe controllers (the probe controller address can also be set according to the site conditions, starting from the 1st order, gradually increasing) can be connected to a collection terminal;
3 The acquisition terminal transmits the parking space information collected from each probe controller to the data processing center (collection terminal No. 1) through the CAN bus. Up to 32 acquisition terminals can be connected to the CAN bus.
4 The data processing center (collection terminal No. 1) transmits the collected data to the PC for management via the serial port (RS485 bus) in real time. The PC then processes and statistics the parking space information. The data processing center can also send information to the collection terminal via the CAN bus. The collection terminal can then publish to the nearby parking space display via wireless or cable to guide the driver to select the driving route.
Central Processing System
Its function analyzes the collected data and displays it on the corresponding output device.
1 It can use the data on the management PC to publish the relevant data of the system through LAN or WAN;
2 GSM wireless MODEM can be connected to the data processing center (No. 1 acquisition terminal) to issue (transmit or receive) relevant data to the City Parking Guidance System Control Center;
3 Parking data release in the parking lot: The LED display screen is mainly connected to the collection terminal. These LED screens are installed at the entrance of the parking lot or the traffic bifurcation junction to indicate the direction of driving and the number of empty parking spaces.
4 When the vehicle enters a specific area of ​​the parking lot, a parking space indicator (vacant green light) connected with the ultrasonic probe at the upper front of the parking space is installed to guide the parking person to park the vehicle in a specific parking space.
Output display system
It consists of a display and guide cards. Working principle The parking lot data is collected in real time by the parking space detector. The system collects parking space-related information and sends the information to the central processing system through the data transmission network according to certain rules. The central processing system carries out the information processing. After the analysis and processing, the relevant processing data will be passed through the output device to provide information for each sign and guide card in the parking lot to guide the vehicle to enter the relevant parking spaces. For the relevant parking space information, the system provides a data query interface.
