System architecture

Real time collection of parking information for each parking spot in the parking lot is achieved through a split type ultrasonic parking spot detector installed directly above each parking spot. When a vehicle is parked in the current parking space, the parking indicator light directly above the parking line changes from green to red. The area controller connecting the detectors will collect information from each connected detector in a polling manner, compress and encode the data according to certain rules, and feedback it to the central controller. The central controller will complete the data processing and send the processed parking space data to the guidance screens of various parking spaces in the parking lot for display of empty parking space information, thereby achieving the function of guiding vehicles into empty parking spaces. The system simultaneously transmits data to the computer, which stores the data on the database server. Users can query real-time parking space information and annual, monthly, and daily statistical data of the parking lot through the computer terminal.

Split type parking guidance, separating the ultrasonic probe from the indicator light. The detector is installed directly above the middle of the parking space, and the split indicator light is installed directly above the front of each parking line to collect real-time parking status data. The parking indicator light is controlled to display red, green, or blue according to the empty status of the parking space.

1. Split type ultrasonic parking detector

The detector is an important component of the parking guidance system, installed directly in front of each parking line. It uses the working principle of ultrasonic ranging to collect real-time parking data in the parking lot, control the display of parking indicator lights, and timely transmit parking information to the regional controller through the 485 network.

A split type ultrasonic parking detector consists of a detector body and indicator lights. The detector body is an ultrasonic probe used to detect the empty and full state of the parking space; The integrated indicator lights display different colors according to the instructions of the detector. When there are no vehicles parked in the parking space, the indicator light is displayed in green. When there are vehicles parked, the indicator light is displayed in red. The fixed parking space indicator light is displayed in blue, and the reserved parking space indicator light is displayed in purple. Multiple colors can be selected.
