Description

Technical Field

[0001] The utility model belongs to the technical field of gas detection, and particularly relates to a coal mine gas detection device based on infrared sensing technology. Background Art

[0002] The main purpose of coal mine gas detection is to ensure the safety of miners. By detecting the gas concentration, the leakage of harmful gases (such as methane and carbon monoxide) can be timely discovered to prevent explosion and poisoning accidents. In addition, the oxygen level can also be monitored to ensure that miners have sufficient breathing oxygen. The detection data helps to take necessary protective measures to avoid accidents;

[0003] Traditional coal mine gas detection devices generally use the filter method to detect gases. Such detection equipment can only perform the detection operation of a single gas and cannot accurately identify multiple different gases.

[0004] Therefore, those skilled in the art have proposed a coal mine gas detection device based on infrared sensing technology to solve the problems raised in the background art.

[0005] The above information disclosed in this background art is only used to increase the understanding of the background art of the utility model. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a coal mine gas detection device based on infrared sensing technology to solve the problems raised in the above background art.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] A coal mine gas detection device based on infrared sensing technology, comprising:

[0009] An installation mechanism, the installation mechanism includes a detector main body, a first installation end and a second installation end. The first installation end and the second installation end are respectively fixedly installed at both ends of the detector main body, and a detection gas chamber is included inside the detector main body;

[0010] A detection mechanism, the detection mechanism includes a broadband light source installed in the first installation end and a processing component arranged in the second installation end. The processing component includes an optical antenna, a PbSe detection chip array and a signal processing module. The optical antenna and the signal processing module are both electrically connected to the PbSe detection chip array.

[0011] Preferably, an air inlet and an air outlet are arranged on the circumferential side of the detector main body, and both the air inlet and the air outlet are communicated with the inside of the detection gas chamber.

[0012] Preferably, a detection spectrum is included on the broadband light source, and the detection spectrum passes through the detection gas chamber and contacts the optical antenna.

[0013] Preferably, a number of sub-detection elements are included on the PbSe detection chip array, and a deep learning algorithm module is included on the signal processing module.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] (1) By providing a first mounting end with a broadband light source and a second mounting end with a processing component in the present utility model, when it is necessary to detect the gas at the coal mine site, the device can be placed at the coal mine site. The gas enters the detection gas chamber from the air inlet and then exits from the air outlet. During the process of gas retention, the broadband light source emits a detection spectrum that passes through the gas and then hits the optical antenna. The optical antenna enhances the received spectrum signal and then transmits it to the PbSe detection chip array. After the gas molecules in the detection gas chamber absorb the infrared light in a specific spectral band emitted by the broadband light source, the light intensity will attenuate. The PbSe detection chip array can determine the gas concentration by measuring the change in the infrared light intensity of these wavelengths. Moreover, multiple sub-detection elements are equipped on the PbSe detection chip array, which can respectively perform targeted detection on different gases, so as to achieve the effect of grouping detection of gases. The data information detected by the PbSe detection chip array will be transmitted to the signal processing module, and the signal processing module can perform intelligent classification and calibration on the measured mixed gas through the deep learning algorithm module, thereby reducing the lower limit of gas detection.

[0016] The above summary is only for the purpose of the specification and is not intended to be limiting in any way. In addition to the above-described illustrative aspects, embodiments, and features, further aspects, embodiments, and features of the present utility model will be readily apparent by reference to the drawings and the following detailed description.

When it is necessary to detect the gas at the coal mine site, this device can be placed at the coal mine site. The gas enters the detection gas chamber 6 from the air inlet 4 and then discharges from the air outlet 5. During the process of gas retention, the broadband light source 7 emits a detection spectrum 8 that passes through the gas and then hits the optical antenna 9. The optical antenna 9 enhances the received spectral signal and then transmits it to the PbSe detection chip array 10.

The PbSe detection chip array 10 can determine the gas concentration by measuring the change in the intensity of the infrared light of these wavelengths. Moreover, the PbSe detection chip array 10 is equipped with multiple sub-detection elements 12, which can respectively perform targeted detection on different gases, so as to achieve the effect of grouping detection of gases. The data information detected by the PbSe detection chip array 10 will be transmitted to the signal processing module 11.
