By installing a front mounted ultrasonic parking detector directly above each parking line, real-time parking information of each parking spot in the parking lot is collected. When a vehicle is parked in the current parking space, the indicator light integrated with the front mounted ultrasonic parking detector 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.

The front mounted ultrasonic parking guidance system adopts a unique front mounted ultrasonic detector to detect parking information. Compared with ordinary ultrasonic probes, the front mounted detector combines the ultrasonic probe with the indicator light and is installed directly above the parking line to collect real-time parking information. The control indicator light represents the status of the parking space and uploads the parking information in real time to the centralized controller.

A front mounted 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.

LInstallation of front mounted ultrasonic detectors

The front mounted ultrasonic detector is installed above the parking line, with a horizontal distance of 0-1 meters from the parking line, and it is recommended to be 0.3-0.5 meters; The installation height is between 2-3 meters, and it is recommended to install at a height of 2.5 meters.

Set the remote control as a replacement for the first generation dial switch, and remotely set the probe distance. The traditional dial switch requires a ladder up and down to adjust the probe during debugging, and remote control can be set by holding the remote control below the probe.
