Roadside parking space monitoring indication device and control method thereof

Abstract

The invention provides a roadside parking space monitoring indication device and a control method thereof. The device comprises a support rod, a wireless electric energy emission source, parking spaceindication modules and a parking space detection module, wherein the parking space indication modules can be cascaded and combined in a modularized manner and are arranged from top to bottom along the axial direction of the support rod. One end of each parking space indication module is a wireless electric energy relay reception end and the other end of the parking space indication module is a wireless electric energy relay emission end. During the cascading, the reception end and emission end of each parking space indication module are adjacent, so that wireless electric energy relay power supply is realized. Each parking space indication module is capable of indicating the parking condition of one parking space or a group of parking spaces. The parking space indication modules are connected with the parking space detection module through wireless communication and are used for obtaining the parking space using conditions so as to realize the indication of parking space vacancy and occupancy. The device can be expanded and spliced at will and is suitable for the using under various parking space quantities. The modules are independent to each other, and wired connection is not required during the mounting, so that the using is convenient; and the parking space indication adopts linear array arrangement, so that the parking space indication is intuitional and the drivers can rapidly obtain nearby parking space information.

Description

technical field [0001] The invention relates to the technical field of automatic detection, in particular to a roadside parking space monitoring and indicating device and a control method thereof. Background technique [0002] With the rapid development of society, the number of private cars has increased significantly in recent years, but the rapid increase in the number of private cars has put a huge pressure on the supply of parking spaces. How to find a suitable parking space in a parking lot is an important issue today. Questions that every car owner should think about. There are several types of existing patents on parking space detection in parking lots: one is to use the camera to judge whether the parking space is free by collecting the changes in the images before and after the parking space. Although it can help the owner to find the parking space quickly to a certain extent, The disadvantage is that it needs to be equipped with a lot of functional modules, the c...

Problems solved by technology

There are several types of existing patents on parking space detection in parking lots: one is to use the camera to judge whether the parking space is free by collecting the changes in the images before and after the parking space. Although it can help the owner to find the parking space quickly to a certain extent, The disadvantage is that it needs to be equipped with a lot of functional modules, the cost is relatively high, and the change of ambient light may cause missed detection; the other is to install an infrared distance measuring device directly above each parking space, and pass the measured distance. The change of the parking space can be used to judge the status of the parking space, but the infrared distance measuring device is prone to false alarms caused by other factors such as dust and people; there is another way to identify the status information of the parking space by placing sensors in polygons, and the increase in the number of sensors also brings cost. increase, complex installation

The above methods all detect the status information of the parking spaces, but they cannot intuitively let each car owner know which parking space is free
