Problems solved by technology

Because the locomotive has the characteristics of relatively simple structure, low manufacturing cost, and convenient maintenance, the underground locomotive is an important process equipment for underground transportation and production of coal mines. , seriously affecting the sight of locomotive drivers
The means of existing technical support are lacking, and it is impossible to accurately locate the position of the locomotive. The on-site dispatchers of the locomotive on the ground cannot know the location of the locomotive in real time and dynamically, so that the ground personnel cannot communicate well with the locomotive driver and correct the locomotive in time. driving state
Therefore, in the process of driving a locomotive, if the locomotive driver is slightly inattentive, unresponsive, and makes mistakes in observation and judgment, locomotive accidents are likely to occur. The occurrence of mine accidents and locomotive accidents seriously affect the production and operation efficiency of underground coal mines

Embodiment 1

[0037] Embodiment 1: Locomotive positioning monitoring in the mine

[0038] The coordinator node distributed underground initializes the protocol stack and establishes a network. The routing node fixedly installed underground initializes the protocol stack, searches for the network, and sends an application to the coordinator to join the network. The coordinator judges whether it is based on the conditions of the routing node. Allow routing nodes to join, and if agreed, assign addresses to routing nodes. The terminal node initializes the protocol, sends a request to the routing node to join the network, and the routing node decides whether to allow joining according to the signal strength of the terminal node, and if allowed, assigns an address to the general segment module. So far, the Zigbee ad hoc network is completed.

[0039] The positioning module is installed on the underground locomotive, and the tag is fixed near the locomotive track. The RFID reader on the locomoti...

Abstract

The invention discloses a locating monitoring method based on RFID. A locating module, a Zigbee route node module, a Zigbee coordinator and an upper computer monitoring module are included. The locating module uses the ultrasonic technology and the RFID technology for sensing the position of a target body and uses the Zigbee wireless ad hoc network technology for transmitting the collected target body position information to the Zigbee coordinator which sends the information to the upper computer monitoring module through the CAN bus technology, and finally real-time monitoring and controlling on the target body position information are achieved. The locating technology based on RFID has the advantages of being high in accuracy, strong in anti-jamming capability, low in cost, flexible in arrangement and the like, and the technology is suitable for locating different target bodies in different places.

Description

technical field [0001] The invention relates to a wireless positioning monitoring method, in particular to an RFID-based wireless positioning monitoring method suitable for occasions where positioning accuracy is high, wireless transmission is required, and real-time dynamic monitoring of a target is required. Background technique [0002] The RFID-based positioning monitoring system uses RFID technology and ultrasonic technology to locate the target body, and uses Zigbee wireless ad hoc network technology and CAN bus to position the information according to a certain data frame format. [0003] The technology is transmitted to the host computer monitoring system, and the host computer analyzes the received information and dynamically displays the location information of the target object on the interface in real time. The underground locomotive is a typical application occasion of this system. Because the locomotive has the characteristics of relatively simple structure,...
