Bluetooth technology based garage gate passing verification method and system

Abstract

The invention provides a Bluetooth technology based garage gate passing verification method and system, and belongs to the technical field of internet of things. In order to solve the problem that in a parking storage process, the system needs to judge whether a demander entering or exiting from a garage is on the scene, at the same time eliminate incorrect trigger operation, accurately screen out a Bluetooth mobile terminal closest to a gate and release a vehicle which the Bluetooth mobile terminal is located at, the verification method and system provided by the invention introduce Bluetooth broadcast equipment, a local Bluetooth server and the Bluetooth mobile terminal which form a triangular Bluetooth interaction relationship, especially the local Bluetooth server is introduced for receiving Bluetooth information sent by the activated Bluetooth mobile terminal to ensure that the Bluetooth mobile terminal is surely on the scene, and in addition, the distance measurement accuracy is improved through two-time distance measurement of the Bluetooth mobile terminal and the local Bluetooth server, so that the screening is more accurate and effective.

Description

technical field [0001] The invention relates to a method and a system for verifying the passing of a garage gate based on the Bluetooth technology, and belongs to the technical field of the Internet of Things. Background technique [0002] Bluetooth technology is an open global specification for wireless data and voice communications, based on low-cost short-range wireless connections, a short-range radio technology that creates a special connection for fixed and mobile device communication environments. Its essence is to establish an open standard for a common radio air interface and its control software, so that portable devices produced by different manufacturers can communicate with each other in a short range without wires or cables connected to each other. Bluetooth technology can realize short-distance data exchange between fixed devices, mobile devices and building personal area networks. The 2.4GHz short-range radio band in the unlicensed Industrial, Scientific and...

Problems solved by technology

[0004] However, the Bluetooth broadcast is usually one-way and the terminals receiving the Bluetooth broadcast may be an unspecified majority, but in many applications in real life, especially in the process of parking in and out of the warehouse, (1) the parking space provider (The garage side) needs to make a specific on-site judgment on the storage demander or the storage demander before making a release (put in or release) decision, and the bluetooth broadcast information of the parking space provider alone is obviously unable to meet this demand. (2) On the basis of the aforementioned problems, it is very likely that there are multiple bluetooth terminals that need to enter / exit the warehouse at the same time, and the bluetooth information that needs to be sent in and out of the gate, or the bluetooth terminal of a member who meets the basic judgment conditions passing by the gate by chance at the same time The bluetooth information required by the entry and exit gates was sent by mistake, but the garage needs to respond to only one parking demand at a time before releasing the gates. At this time, there is still a garage side that chooses to release the actual bluetooth terminal closest to the gates , In addition, most of the current Bluetooth ranging errors are relatively large and will be affected by the operating platform on which the Bluetooth mobile terminal is tested, so improving the accuracy of ranging is also a problem that needs to be solved
