Parking lot stall monitoring system based on radio frequency identification technology and working method

Abstract

The invention discloses a parking lot stall monitoring system based on a radio frequency identification technology and a working method of the parking lot stall monitoring system. The parking lot stall monitoring system mainly comprises a radio frequency identification reader, a radio frequency identification external antenna, a radio frequency identification tag, and a background radio frequency signal processing server. The background radio frequency signal processing server also comprises a stall real-time detection engine and a stall navigation display interface. In the system, whether a stall has a vehicle or not and whether a vehicle is parked safely in place or not can be sensed by arranging an appropriate radio frequency identification tag array in a space and utilizing the characteristic that a wireless radio frequency signal which is reflected by the tag is attenuated after being shielded by a ferromagnet, so that the data reference can be provided for a parking lot management system. The invention provides a mechanism for automatically detecting an empty stall with low cost, so that a navigation mechanism can be provided for searching the stall, the quantity and the position of the empty stall can be displayed in real time through an interference-friendly way, and whether the vehicle is parked safely or not can be detected.

Description

[0001] technical field [0002] The invention relates to a parking space monitoring system and working method, specifically a radio frequency identification (RFID) technology based on the characteristics of non-contact wireless transmission of radio frequency identification, by deploying corresponding radio frequency tag arrays and vehicle body pairs in physical space Analyze the interference characteristics of radio frequency signals, realize the non-contact recognition parking space monitoring system and its working method. Background technique [0003] According to incomplete statistics, the number of cars in China in 2012 was 123.13 million. Such a large number of cars requires a lot of parking space. Especially in cities, it is hard to find a parking space to become a chronic disease in the city. How to efficiently use limited parking spaces is an important means to solve the scarcity of parking spaces. [0004] The existing parking space monitoring system can only se...

Problems solved by technology

[0004] The existing parking space monitoring system can only sense whether there is a vehicle in the parking space, and then simply display the information above the parking space in the form of traffic lights. There is no parking at all times, and a large number of car owners wander in the parking lot disorderly looking for parking spaces, which not only affects traffic, but also easily causes accidents; this situation is very common in underground parking lots

In addition, when the vehicle is parked incorrectly in the parking space, the existing parking space monitoring system cannot give the driver a reminder, resulting in the phenomenon that one car sometimes occupies two parking spaces
