Structure and working principle of parking guidance system
The parking guidance system consists of three parts:
1. The first part is the data acquisition system: it consists of vehicle detectors and controllers.
2. The second part is the central processing system: its function analyzes the collected data and displays it on the corresponding output device.
3. The third part is the output display system: it consists of a display screen and a guide card.
Parking guidance system works:
Through the Koto parking sensor, the parking spaces of the parking lot are collected in real time. The regional controller collects relevant information of the parking lot detectors according to the polling method and feeds back the data according to certain rules. The main controller, after analyzing and processing the parking information of the parking lot of the entire parking lot by the main controller, sends information to each sign and guide card in the parking lot to guide the vehicle to enter the relevant parking space. At the same time, the data is transmitted to the computer. The computer stores the data in the database server. The computer system provides the data query interface. The system can run independently from the computer.
