It is not only easy to cause congestion and disorder in nearby traffic, but also cause The driver’s psychologically heavy burden and extreme inconvenience. As far as we know, most parking control mechanisms for toll parking lots are mainly based on manpower for vacant or occupancy monitoring. When there is no parking space in the parking lot, the display above the entrance gate is displayed. It will show that there is no information on the space; on the contrary, when the parking lot has a vacant parking space, even if the entrance gate shows vacancies, but the average driver can not know further the actual location and quantity of the vacant parking space? Therefore, it is impossible to know the information of the empty space and the occupancy status of each parking space in the first time, so that there will be a situation in which the parking space is seized and an accidental situation of the dangerous car is likely to occur, thereby causing inconvenience and trouble for the driver to stop.

In addition, another conventional parking management technology can sense and display the air/occupancy information of each parking space, and an infrared detector is disposed in each parking space of the parking lot to detect whether the parking space has a vehicle. Parking, and transmitting a sensing signal to the display panel of the center console according to the space/occupancy, so that the administrator of the center console can identify the distribution information of the parking state of the vehicle according to the color of the light, so that the vehicle can be commanded to enter the vacancy State of the parking compartment, although the prior art has Automatic detection and display of the function of empty/occupation, but the use of infrared detectors is easy to be accidentally touched by cats and dogs, or because the parking position of the vehicle is not positioned in the parking space, or the obstacles are blocked and false alarms are generated. The situation arises, which in turn causes inconvenience and great troubles in the control of the central control vehicle. Therefore, such a conventional structure does have the need for further improvement.
