System Structure:

• Through the split ultrasonic parking space detector installed directly above each parking space, the parking space information of each parking space in the parking lot can be collected in real time. When a vehicle is parked in the current parking space, the parking space indicator directly above the parking space line changes from green to red. The area controller connected to the detector will collect the information of each connected detector according to the polling method, and will compress and encode the data according to certain rules and then feed it back to the central controller. The central controller will complete the data processing, and The processed parking space data is sent to each parking space guide screen of the parking lot to display the vacant parking space information, so as to realize the function of guiding the vehicle into the vacant parking space. The system transmits the data to the computer at the same time, and the computer stores the data in the database server. The user can query the real-time parking space information of the parking lot and the year, month, and day statistical data of the parking lot through the computer terminal.
• Split-type ultrasonic parking space guidance topology map Split-type parking space guidance, separate 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 space line to collect parking space status data in real time, and control the parking space indicator to display red, green or blue according to the full empty status of the parking space.

Split Ultrasonic Parking Space Detector

The detector is an important part of the parking guidance system. The probe is installed directly in front of each parking line. It uses the working principle of ultrasonic distance measurement to collect real-time parking data of the parking lot, control the display of the parking indicator, and keep the parking information in time. It is transmitted to the regional controller through the 485 network.

A split ultrasonic parking detector is composed of a detector body and an indicator light. The detector body is an ultrasonic probe, which is used to detect the empty or full state of the parking space; and the integrated integrated indicator light shows different colors according to the instructions of the detector. . When there is no vehicle parked in the parking space, the indicator light is green, when there is a vehicle parked, the indicator light is red, the fixed parking space indicator light is blue, and the reserved parking space indicator light is purple. Multi-color options are available.
