Embodiment 1

[0030] An RFID-based smart helmet surrounding environment information collection system, such as figure 1 shown, including a variety of sensors and programmable passive RFID tags installed in a smart helmet, as well as an RFID reader and management backend. Programmable passive RFID tags obtain energy from the received radio frequency signal and store energy without additional power supply, and can provide energy for a variety of sensors. The programmable passive RFID tag obtains the environmental data of the smart helmet and the movement acceleration data of the smart helmet through a variety of sensors, and stores and processes the acquired data and sends it to the RFID reader through a radio frequency signal. The data is transmitted to the management background for data management.

[0031] The various sensors include a temperature sensor, a brightness sensor, an acceleration sensor and an image sensor, wherein the temperature sensor, the brightness sensor and the accelera...

Embodiment 2

[0045] This embodiment provides the collection method of the collection system of the first embodiment. The collection method mainly includes three parts, the communication part between the WISP tag and the RFID reader, the middleware program part and the management background data management part.

[0046] The WISP tag and reader constitute the front-end part of the acquisition system, which are mainly used to obtain information such as light intensity, temperature, and acceleration of the helmet's movement in the environment where the helmet is located. The management background constitutes the back-end part of the data management, and the middleware program is Connecting the front-end and the back-end, the middleware program will drive the front-end work, and store the data obtained by the front-end in the back-end database for use in the management background. The management background adopts the B / S architecture.

Abstract

The invention discloses an intelligent safety helmet surrounding environment information acquisition system and method based on RFID (Radio Frequency Identification Device), and a method and system for acquiring safety helmet surrounding environment information in real time are constructed by combining a programmable RFID tag and various sensors. According to the invention, an embedded image sensor is adopted, a gray level image of a surrounding environment is obtained by using less energy and computing resources, and information is stored in a storage area of the programmable RFID tag. And the programmable RFID tag keeps interacting with the RFID reader, continuously sends the obtained sensing information to the RFID reader, and stores the sensing information into a management background database. When the management background detects abnormal conditions such as falling down, the image sensor is started to obtain gray level image information of the environment where the intelligent safety helmet is located. The system has the advantages of being low in cost, easy to maintain, high in real-time performance and good in function expansibility.

Description

technical field [0001] The invention belongs to the technical application field of the Internet of Things, and relates to a peripheral environment information collection method of an intelligent safety helmet. Background technique [0002] With the development of computer and Internet of Things technology, RFID (Radio Frequency Identification) technology has been continuously developed, and different application types are constantly increasing. At present, in the field of fall monitoring, RFID technology has also attracted the attention of many researchers. According to the World Health Organization, falls are the second leading cause of unintentional injury and death globally. More than 37.3 million people are injured by falls each year, and 646,000 people die as a result of falls directly or indirectly. During construction on the construction site, the safety problem caused by falls is particularly serious, and it should be paid enough attention. In order to ensure the s...
