Abstract
A temperature sensor for a coal mine belongs to the field of detecting instruments and comprises a central processing unit, a display unit, a temperature detecting unit, a signal output unit, an alarming unit and a power supply. The central processing unit comprises a single-chip microcomputer and an analog/digital (A/D) converter. The central processing unit is connected with the display unit, the temperature detecting unit, the signal output unit, the alarming unit and the power supply through different interfaces. The temperature detecting unit comprises a sampling head, and the sampling head converts collected temperature signals into analog voltage signals through the A/D converter and transmits the voltage signals to the single-chip microcomputer to be processed. The display unit displays measured temperature value, the alarming unit produces alarming signals when the temperature value displayed by the display unit is high, a signal transmission unit transmits signals to outside relevant devices, remote centralized monitoring is achieved, and the power supply supplies power to the device in real time. The temperature sensor for the coal mine has the advantages of being high in sensitivity, stable in performance, long in service life, and the like.
