A public place visitors flow rate monitor method based on RFID

Abstract

The invention discloses a public place visitors flow rate monitor method based on RFID. The method comprises the following steps of setting up a visitors flow rate monitoring system based on RFID in a public place, and measuring a large amount of data according to the system; establishing a reference value and an extreme value for judging the current visitors flow rate; acquiring real-time data, which includes extracting the population coverage area based on LSI and obtaining population movement speed and the range detection data; and comparing the obtained data with a current standard to judge the current visitor flow situation. According to invention, RFID technology related equipment is high in cost performance, and has a characteristic of high environment resistance, so that investment cost can be substantially reduced; in a public place where a crowd do not carry cards embedded with electronic labels, the current flow of people can also be subjected to real-time monitoring; the LSI can be used to analyze the population coverage, so that not only can the current test results be verified, but also certain prediction can be made for short-term changes in the flow of people.

Description

technical field [0001] The invention belongs to the technical field of people flow monitoring, in particular to an RFID-based method for monitoring people flow in public places Background technique [0002] Radio Frequency Identification (RFID) is an automatic identification technology that transmits data through radio waves. The working principle of RFID is to use radio frequency signals to realize the transmission of contactless information and achieve the purpose of object identification. RFID technology does not need direct contact with objects, that is, it can realize identification at a long distance, and can process information quickly, in real time and accurately. It is also one of the ten important technologies in the 21st century. [7] The RFID system is mainly composed of an electronic tag (Tag), a reader (Reader and Writer) and an application system. The electronic label has a unique electronic product code within the system. In practical applications, the elec...

Problems solved by technology

On December 31, 2014, a stampede on the Bund in Shanghai caused 36 deaths and 47 injuries. On September 24, 2015, a stampede of pilgrims in Mecca Mina, Saudi Arabia caused 717 deaths and at least 805 injuries. The accident shows that the safety of public places needs to be further improved

[0017] The cost of these three people flow detection methods is high, and the later maintenance is more troublesome
