Data collection and device positioning method based on RFID under mine environment

Abstract

The invention discloses a data collection and device positioning method based on RFID under a mine environment. The method includes the steps of arranging a wireless sensor node network under the mineenvironment; positioning each mine device and mapping coordinates of sensor nodes in the wireless sensor network through RFID labels; collecting data of the sensor nodes within an identification range through a low-power RFID reader, then writing the data and the position information of the devices into data areas of the RFID labels, forwarding data of the data areas to a high-power RFID reader through the RFID labels, and transmitting the data to a background data center for analysis to achieve positioning of targets and monitoring of errors of the devices. Combined storage and forwarding ofdata are carried out through an RFID technology and a WSN technology, and the stability and reliability of data collection are improved. By using the RFID readers different in power, the purpose of reducing energy consumption is achieved.

Description

technical field [0001] The invention belongs to the field of data collection and equipment positioning, and in particular relates to a real-time information collection of environmental data parameters in a mine environment and a method for positioning equipment. Background technique [0002] Radio frequency identification (RFID) technology and wireless sensor network (wireless sensor networks, WSN) technology are two key technologies of the Internet of Things. RFID technology is a non-contact automatic identification technology that automatically identifies target objects and acquires data through radio frequency signals without the need to establish mechanical or optical contact between the identification system and specific targets. The RFID system is mainly composed of readers, RFID tags and host systems. Due to different power supply methods, RFID tags can be divided into active tags and passive tags (reference document [1]). The active tag carries its own battery and ...

AI Technical Summary

Problems solved by technology

However, building a sensor network requires a large number of sensor nodes and RFID tags, and the communication effect is limited by the wireless communication quality in the mine environment. Using a large number of readers to process tags puts forward higher requirements for communication quality (reference document [5]); And whether the equipment failure is related to the environment cannot be discovered in time, which is not conducive to the monitoring and analysis of the staff
