Indoor positioning method of intelligent safety helmet

Abstract

The invention discloses an indoor positioning method of an intelligent safety helmet. The indoor positioning method of the intelligent safety helmet is implemented by devices including a safety helmet, intelligent LED lamps, a wireless gateway, an outdoor WiFi hotspot and a cloud server, wherein the intelligent LED lamps are installed on the top in a room and distributed on the same in an array; Bluetooth modules are installed in the intelligent LED lamps and form a network via an ad-hoc network protocol, the network formed by the intelligent LED lamps is connected with the outdoor WiFi hotspot via the wireless gateway, and the outdoor WiFi hotspot is connected with the cloud server. The Bluetooth modules arranged in the safety helmet read position information of the Bluetooth modules in the five closest intelligent LED lamps, the safety helmet uploads the position information to the cloud server via an ad-hoc network, and the cloud server computes the position information of the safety helmet via an algorithm routine. According to method provided by the invention, the devices are simple in structure and convenient to arrange, implementation of the method is facilitated, and indoorpositioning can be accurately performed on the safety helmet.

Description

technical field [0001] The invention relates to the technical field of positioning, in particular to an indoor positioning method for a smart helmet. Background technique [0002] The hard hat is a shallow dome hat made of steel or similar materials worn to protect the top of the head. As one of the safety protection tools for indoor and outdoor engineering operations, the working environment of engineering operations is relatively dangerous, with scattered operating locations, limited operating space and The management of safety helmets and other reasons can easily lead to loopholes in supervision, and the monitoring personnel cannot understand the operators in real time. Therefore, the positioning function of safety helmets is very important. Generally, safety helmets realize network positioning through WiFi and other methods, and the WiFi signals of general construction sites have limitations. , the ability of the signal to pass through the wall is weak, and it cannot sat...

[0002] The safety helmet is a shallow dome hat made of steel or similar materials worn to protect the top of the head. As one of the safety protection tools for indoor and outdoor engineering operations, the working environment of engineering operations is relatively dangerous, with scattered operating locations, limited operating space and The management of safety helmets and other reasons can easily lead to regulatory loopholes, and the monitoring personnel cannot understand the operators in real time. Therefore, the positioning function of safety helmets is very important. Generally, safety helmets realize network positioning through WiFi and other methods, and the WiFi signals of general construction sites have limitations. , the ability of the signal to pass through the wall is weak, and it cannot satisfy people's pursuit of connecting to the Internet anytime and anywhere. The lighting device is the most unobstructed, widest and most evenly distributed in the building. How to use the location advantage of the lighting device is better. The spread of WiFi signals has become an urgent need for users
