RFID Coal Mining Temperature Measurement Solution

In the past, the coal mining industry mainly relied on manual inspections to troubleshoot heating and safety problems. Under harsh weather conditions, it was difficult to detect temperature and meet the requirements of efficient, real-time and safe monitoring. The specific performance is as follows

1. High risk of coal mine environment
Flammable and explosive risks: There are flammable and explosive substances such as gas (methane) and coal dust in coal mines. Overheating of equipment or cables may cause fires or even explosions.

2. High temperature hazards: Mining machinery, motors, transformers and other equipment are prone to overheating after long-term operation, leading to failures or safety accidents.

3. Harsh environment: high humidity, high dust, corrosive gases, etc. affect the stability and life of traditional temperature measurement equipment.

4. Limitations of traditional temperature measurement methods
Wired temperature measurement: complex wiring, difficult maintenance, and difficult to apply on underground mobile equipment (such as coal mining machines and conveyors).

Manual inspection: relying on manual handheld thermometers, low efficiency, data lag, and no real-time warning.
Infrared temperature measurement: greatly affected by dust and humidity, and unable to achieve 24-hour continuous monitoring.

In this case, with the development of RFID technology, RFID wireless temperature measurement solutions have emerged. By combining RFID technology with temperature sensing technology, real-time temperature monitoring of key equipment and areas in coal mines can be achieved to prevent safety accidents caused by abnormal temperature.

RFID System composition
RFID temperature tag: high temperature resistant, explosion-proof design, in line with coal mine safety standards, built-in high-precision temperature sensor, working frequency 2.4GHz or 433MHz (selected according to the mine environment), battery life 3-5 years (low power design)

RFID Reader and writer equipment: mine intrinsically safe or flameproof design, reading distance 10-100 meters (depending on the specific environment), support for simultaneous reading of multiple tags, strong anti-interference ability

Data transmission network: wired/wireless hybrid networking, industrial-grade switches and gateways, support for docking with existing coal mine monitoring systems

Monitoring center software: real-time temperature data display and storage, multi-level alarm mechanism (early warning, alarm, emergency alarm), historical data query and analysis, report generation function

Advantages of RFID wireless temperature measurement
Wireless deployment, no wiring required: suitable for underground mobile equipment (such as coal mining machines, belt conveyors) and long-distance monitoring points.
Real-time monitoring, automatic alarm: temperature data can be uploaded to the monitoring center in real time, and over-temperature alarms are immediately issued to reduce accident risks.
Explosion-proof and high-temperature resistant design: in line with coal mine safety standards and adaptable to harsh environments.
Long-term stable operation: low-power RFID tags have a long service life, reducing the trouble of frequent replacement.
In line with the development trend of intelligent coal mines

Application scenarios
Monitoring of key underground equipment: bearing temperature of large equipment such as coal mining machines, tunneling machines, conveyors, and electrical equipment such as motors and transformers
Environmental temperature monitoring: mining working face temperature, key node temperature of tunnels, gas extraction pipeline temperature
Cable temperature monitoring: high-voltage cable joint temperature, cable trench temperature distribution
