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 is collected in real time. When there is a vehicle parked in the current parking space, the parking space indicator light directly above the parking space line changes from green to red. The regional controller connected to the detector will collect the information of each connected detector according to the polling method, and compress and encode the data according to certain rules and feed it back to the central controller. The processed parking space data is sent to each parking space guidance screen of the parking lot to display the empty parking space information, so as to realize the function of guiding the vehicle to enter the empty parking space. At the same time, the system transmits the data to the computer, 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 statistical data of the year, month and day of the parking lot through the computer terminal.

2.Split-type parking space guidance, separates the ultrasonic probe from the indicator light. The detector is installed just above the middle of the parking space, and the split indicator light is installed directly above each parking space line to collect the parking space status data in real time, and control the parking space indicator light to display red, green or blue correspondingly according to the full empty state of the parking space.

4.working principle of Split Ultrasonic Detector

The detector is an important part of the parking space guidance system. The probe is installed in front of each parking space line. The working principle of ultrasonic ranging is used to collect real-time parking space data of the parking lot, control the display of the parking space indicator, and at the same time, the parking space information is timely It is transmitted to the zone controller via the 485 network.

A split-type ultrasonic parking space detector consists of a detector body and an indicator light. The detector main body is an ultrasonic probe, which is used to detect the empty state of the parking space; while the 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 is blue, and the reserved parking space indicator is purple, which can be selected from multiple colors.
