Parking lot parking space detection system and electronic label

Abstract

The invention discloses a parking lot parking space detection system. Activation units are arranged in the middle of a left line and the middle of a right line of a parking space respectively, and each activation unit sends an activation signal with an address code of the activation unit in a wireless mode in a first frequency band. Vehicle electronic labels entering the activation signal range send vehicle locating data every other label work cycle in a second frequency band according to activation unit address codes obtained through activation signal analysis and field intensities of corresponding activation signals. A reader sends the vehicle locating data to a data server, and the data server determines vehicle label positions according to vehicle electronic label identification codes, activation unit address codes and the field intensities of the corresponding activation signals in the vehicle locating data. Moreover, if the position of a vehicle label does not change within a time period, a parking state is determined, so that whether a parking space is occupied and the identities of vehicles in all occupied parking spaces can be accurately judged. The invention further discloses an electronic label.

Description

technical field [0001] The invention relates to network information and digital sensing technology, in particular to a parking space detection system and an electronic label in a parking lot. Background technique [0002] With the rapid development of the automobile industry, the problem of difficult parking in cities has become more and more prominent. It is imminent to improve parking facilities, collect and share real-time information on the occupancy and location of parking spaces in each parking lot, and improve the efficiency of parking and picking up cars. At present, most of the parking lots are managed by the parking lot staff to divide the parking spaces. This kind of parking lot management method has the following problems: [0003] 1. In an area of ​​the city, some parking lots may be full of parking spaces, but the owner enters the parking lot because he cannot know the parking space conditions of the parking lot in advance. Poor air environment and other probl...

Problems solved by technology

[0003] 1. In an area of ​​the city, some parking lots may be full of parking spaces, but the owner enters the parking lot because he cannot know the parking space conditions of the parking lot in advance. Poor air environment and other problems; at the same time, some parking lots may have a large number of vacant parking spaces, and the owner did not enter the parking lot because he could not know the parking space conditions of the parking lot in advance, resulting in the parking space being empty and making the parking space useless. low rate

[0004] 2. When the owner returns to the parking lot to pick up the car, due to the complex internal conditions of the parking lot, or forgetting the parking position of his vehicle, it is often difficult for the owner to find his vehicle quickly and accurately, resulting in a waste of time

[0006] In the parking space detection system disclosed in Chinese patent application 201110438363.X, the monitor 20 is located behind the parking space. It may not be recognized by the monitor 20 of the parking space where it is located, or the electronic tag in the vehicle is mistakenly recognized by the monitor 20 of the adjacent parking space, and the accuracy of the monitoring of the parking space cannot be guaranteed

[0020] The reverse car search system disclosed in Chinese patent 201020554925.8 needs to set up a main control device, multiple liquid crystal query terminals and multiple positioning terminals, and the cost is relatively high. Swipe the card, you need to swipe the card at the positioning terminal or query terminal when looking for a car, the operation is cumbersome
