The invention relates to a temperature sensor for a coal mine. The temperature sensor for the coal mine comprises a single-chip microcomputer, a display module, an alarm module, a power supply module, an A/D convertor, a temperature detection module, a protection circuit, a communication module and a control system, wherein the temperature detection module is sequentially connected with the A/D convertor and the single-chip microcomputer, the display module, the alarm module, the power supply module, the protection circuit and the communication module are all connected with the single-chip microcomputer, and the control system is connected with the communication module. The temperature sensor for the coal mine adopts the single-chip microcomputer, so that the structure of a circuit is simple, the performance is reliable, the maintenance is facilitated, the functions of adjusting zero and sensitivity through remote control are achieved due to the use of the communication module and the control system, the existing defects of low accuracy and large measurement error are overcome, and the high accuracy and the high stability of the sensor in operation are achieved.
Description
Technical field
The present invention relates to detecting instrument field, particularly a kind of coal mining temperature sensor.
Background technology
Under coal mine, be full of inflammable gas, when down-hole ambient temperature reaches certain value, the in the situation that of oxygen abundance, can there is even blast of burning in inflammable gas, bring serious accident, for effective trouble-saving generation, temperature sensor is all installed, for the size of real-time testing environment temperature in down-hole.Personnel in the pit can understand ambient temperature value by directly observing the displayed value of temperature sensor, and personnel understand the ambient temperature value of current down-hole by the output signal of temperature sensor on the ground.The output signal of temperature sensor is frequency signal, and this output signal arrives on the ground by cable transmission, and after corresponding calculating, this output signal converts corresponding temperature value to.The conventional temperature sensor in existing colliery mainly contains all kinds of platinum resistors, semiconductor heat dependent sensor, integrated temperature sensor etc., its sensing output signal or have non-linear, or can not transmit by telecommunication, exist the shortcomings such as precision is low, measuring error is large, job insecurity, poor reliability, serviceable life is short.
Summary of the invention
For above-mentioned defect and the problem of prior art, the object of the invention is to provide a kind of coal mining temperature sensor, reduces measuring error, realizes the stability of work.
In order to achieve the above object, the present invention realizes by the following technical solutions:
A kind of coal mining temperature sensor, comprise single-chip microcomputer, display module, alarm module, power module, A/D transducer and temperature detecting module, described temperature detecting module connects A/D converter, single-chip microcomputer successively, and described display module, alarm module, power module are all connected with single-chip microcomputer.
Further technical scheme, also comprises holding circuit, and described holding circuit is connected with single-chip microcomputer.
Further technical scheme, also comprises communication module and control system, and described communication module is connected with single-chip microcomputer, described control system connecting communication module.
The present invention adopts single-chip microcomputer, makes circuit structure simple, dependable performance, be convenient to maintenance, use communication module, realized the functions such as Remote adjustment zero point, sensitivity, solved and existed the shortcomings such as precision is low, measuring error is large, realized high precision, the high stability of working sensor.

Shown in Fig. 1; the present invention is a kind of coal mining temperature sensor; comprise single-chip microcomputer, display module, alarm module, power module, A/D transducer, temperature detecting module, holding circuit, communication module and control system; described temperature detecting module connects A/D converter, single-chip microcomputer successively; described display module, alarm module, power module, holding circuit, communication module are all connected with single-chip microcomputer, described control system connecting communication module.
Complete machine principle of work of the present invention is:
Power module provides working power for sensor;
Temperature detecting module sends the temperature signal detecting to A/D transducer;
A/D transducer is transformed into digital signal by the signal receiving, and is sent to single-chip microcomputer;
Holding circuit maintains the stable of working sensor power environment;
Single-chip microcomputer carries out after computing and processing, concentration value being shown by display module to digital signal;
When a certain limit value that temperature surpass to set being detected, single-chip microcomputer trigger alarm module is reported to the police;
Communication module is real-time transmitted to long-range control system by the result detecting; Tele-control system sends to single-chip microcomputer by communication module by the setting of needs.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; can expect easily changing or replacing, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion by the described protection domain with claim.
