Summary of the invention
Present invention seek to address that one of the above-mentioned problems of the prior art, provides a kind of monitoring mining device, the mine
Well monitoring device can be implemented effectively to detect the methane concentration in mine, and detection data is accurate, high reliablity.
To achieve the goals above, the present invention provides a kind of monitoring mining device, comprising: detection module, the detection mould
Block is used to obtain the methane concentration signal in mine；Control module, the control module are connected with the detection module, for pair
The amplitude of the detection module methane concentration signal obtained judges in first time compared with the threshold value of its inner setting
Whether the cumulative time that the amplitude of the humidity is greater than or equal to humidity threshold was greater than for the second time, and big in the cumulative time
Alarm signal is generated when the second time；And alarm module, it is connected with the processing module for alarming.
In the technical scheme, the methane concentration value in mine can be effectively detected by detection module, and by methane
Concentration value is transmitted to control module, compared with the methane concentration threshold value in control module, when methane concentration amplitude is greater than or waits
When threshold value, alarm signal is generated by alarm module and generates alarm, prompt worker to the methane concentration in mine to carry out necessity
Flee from, and the monitoring mining apparatus structure is simple, and detection data is accurate, high reliablity.
In addition, monitoring mining device according to the present invention, can also have following technical characteristic:
Further, the detection module includes: methane detector, to measure the methane concentration signal in mine.
Preferably, the control module includes: decoding signals, and the decoding signals and the methane detector connect
It connects, is converted to digital signal for receiving the methane concentration signal, and by the methane concentration signal.
Preferably, the decoding signals include: analog-digital converter, are used for the amplified methane concentration degree signal
Be converted to digital signal；And filter circuit, for being filtered to the digital signal.

Compared with, judge whether the amplitude of the humidity in first time was greater than for the second time more than or equal to the cumulative time of humidity threshold,
And alarm signal is generated when the cumulative time being greater than for the second time；And
Alarm module 30 is connected for alarming, by control module 20 after generating alarm signal with the processing module
It controls alarm module 30 and generates alarm, to prompt worker to carry out methane concentration adjusting.
It is understood that can effectively detect the methane concentration value in mine by detection module 10, and by methane
Concentration value is transmitted to control module 20, compared with the methane concentration threshold value in control module 20, judges described in first time
Whether the cumulative time that the amplitude of humidity is greater than or equal to humidity threshold was greater than for the second time, and was greater than the in the cumulative time
Alarm signal is generated when two time；When methane concentration amplitude is greater than or equal to threshold value, alarm signal is generated by alarm module 30
Generate alarm, prompt worker the methane concentration in mine is carried out it is necessary flee from, and monitoring mining apparatus structure letter
Single, detection data is accurate, high reliablity.
Further, the detection module 10 includes: methane detector 110, to measure the letter of the methane concentration in mine
Number, the methane concentration in mine can be effectively detected by methane detector 110.
Preferably, the control module 20 includes: decoding signals 21, the decoding signals 21 and the CH_4 detection
Instrument connection, is converted to digital signal for receiving the methane concentration signal, and by the methane concentration signal.
Preferably, the decoding signals 21 include: analog-digital converter 211, for converting the methane concentration signal
For digital signal；With filter circuit 212, for being filtered to the digital signal.
Although the embodiments of the present invention has been shown and described above, it is to be understood that above-described embodiment is example
