[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] The terms "first", "second", etc. in the specification and claims of the present utility model and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0040] Reference to "embodiment" or "implementation method" herein means that the specific features, structures or characteristics described in conjunction with the embodiment or implementation method may be included in at least one embodiment of the utility model. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0041] At present, in order to detect various parameters in coal mines in related technologies, it is necessary to use a variety of different equipment to carry out detection in coal mines. However, due to the small space in coal mines, using multiple devices for detection not only consumes a lot of power, but also requires multiple wires to power the equipment. At the same time, the detection equipment will also occupy a larger space in the coal mine, which makes the already small coal mine space even more crowded.

[0042] In view of this, a sensor monitoring device 100 applied to coal mine ecological monitoring is provided, and the sensor monitoring device 100 for coal mine ecological monitoring can reduce the occupation of coal mine space.

[0043] See also Figure 1 and Figure 2 The utility model provides a sensor monitoring device 100 for coal mine ecological monitoring, comprising:

[0044] A housing 10, wherein the housing 10 has a first surface 11 and a second surface 12 that are oppositely disposed;

[0045] An acquisition module 20, the acquisition module 20 comprising a PCB board 21, a temperature sensor 22, a carbon monoxide sensor 23, and a gas sensor 24, the PCB board 21 being disposed on the first surface 11, the temperature sensor 22, the carbon monoxide sensor 23, and the gas sensor 24 being disposed on the PCB board 21, and the temperature sensor 22, the carbon monoxide sensor 23, and the gas sensor 24 being electrically connected to the PCB board 21;

[0046] A signal processing module 30, wherein the signal processing module 30 is disposed in the housing 10 and is electrically connected to the acquisition module 20;

[0047] The transmission module 40 is disposed on the second surface 12 , and the transmission module 40 is connected to the signal processing module 30 .

[0048] In the actual coal mine production environment, the underground environment is complex, the space is small, and the light is dim. The technical requirements and difficulty of deploying multiple devices underground are relatively large, and it is difficult to uniformly manage the hardware equipment and collected data after the dispersed deployment. The above-mentioned sensor monitoring device 100 in the embodiment of the present application can reduce the number of sensors set in the coal mine, reduce the congestion in the mine, and reduce the difficulty of deploying sensor equipment, further improving the efficiency of hardware equipment management and data overall planning.

[0049] Specifically, the temperature sensor 22, carbon monoxide sensor 23, and gas sensor 24 in the acquisition module 20 can be used to detect multiple environmental parameters. After obtaining multiple environmental parameters, they are processed by the signal processing module 30 and then transmitted to the monitoring equipment through the transmission module 40, thereby realizing the detection of environmental parameters in the mine. The outer shell can also protect and fix the acquisition module 20, the signal processing module 30, and the transmission module 40. The device can be powered by connecting an electric wire to the electrical equipment.

[0050] It can be understood that the acquisition module 20 is used to obtain the parameters of the ecological environment in the coal mine. The detection content of the acquisition module 20 can be set according to the type of detection required in the coal mine. In the present utility model, the temperature, carbon monoxide, and gas detection are used as examples for explanation. Specifically, the temperature sensor 22, the carbon monoxide sensor 23, the gas sensor 24 and other sensors are integrated on the PCB board 21, so that they are electrically connected to the PCB board 21, and the relevant electrical signals are transmitted to the PCB board 21 to realize the collection of the required detection parameters. In other embodiments, other sensors such as humidity detection sensors, concentration sensors, and wind speed sensors can also be set on the PCB board 21 to detect the ecological environment of the coal mine.

[0051] See also Figure 1 , Figure 7 , Figure 8 and Fig. 9 , in some embodiments, further comprising: a protective shell 50;

[0052] The protective shell 50 is disposed on the first surface 11; the protective shell 50 includes a first plate 51, a second plate 52, a third plate 53, and a fourth plate 54 which are connected end to end in sequence;

[0053] The first plate 51 and the third plate 53 are arranged obliquely, and an extension line of the first plate 51 and an extension line of the axis of the housing 10 form an angle α;

[0054] The second plate 52 and the fourth plate 54 are arranged obliquely, and an extension line of the second plate 52 and an extension line of the axis of the housing 10 form an angle β.

[0055] It can be understood that the protective shell 50 is used to protect the acquisition module 20. Specifically, the protective shell 50 is composed of a first plate 51, a second plate 52, a third plate 53 and a fourth plate 54, and the first plate 51, the second plate 52, the third plate 53 and the fourth plate 54 are connected end to end in sequence to form a cylindrical protective shell 50; the first plate 51 and the third plate 53 are relatively inclined, the second plate 52 and the fourth plate 54 are relatively inclined, and the side extension line of the first plate 51 and the corner extension line of the shell 10 form an angle, and the side extension line of the third plate 53 and the corner extension line of the shell 10 form an angle. Since the inclination angles of the first plate and the second plate are the same, the angle formed by the two is α. For details, please refer to Figure 8 .

[0056] The side extension line of the second plate 52 and the side extension line of the fourth plate 54 both form an angle with the angle extension line of the shell, and the inclination angles of the second plate 52 and the fourth plate 54 are also the same, so the angle formed by the two is β. In this way, after the protective shell 50 is connected, one end of the protective shell 50 gradually increases toward the other end, and the larger end is connected to the second surface 12 to achieve the fixation of the protective shell 50. At the same time, the protective shell 50 gradually increases from one end to the other end in order to protect the acquisition module 20 while ensuring that the acquisition module 20 can detect relevant data, so as to avoid the harsh environment of high temperature, high humidity, high dust, and high gas in the mine from damaging the acquisition module 20, and affecting the measurement accuracy of the acquisition module 20 after long-term use.

[0057] See also Figure 7 and Figure 8 In some embodiments, the angle α is in the range of 10°≤α≤60°.

[0058] It can be understood that the extension line of the first plate 51 and the extension line of the third plate 53 form an angle α, and the range of α is 10°≤α≤60°. Specifically, the above angle can be 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60° and other angles. The size of the angle will affect the size of the opening of the protective shell 50 away from the second surface 12. If the angle is small (less than 10°), it may cause the acquisition module 20 to detect fewer samples, affecting the detection accuracy of the acquisition module 20. If the angle is large, more samples will enter the protective shell 50, affecting the service life of the acquisition module 20. Preferably, the angle α in the present invention is preferably 20° to ensure the detection accuracy of the acquisition module 20.

[0059] See also Figure 7 and Fig. 9 In some embodiments, the angle β is in the range of 10°≤β≤60°.

[0060] It can be understood that the extension line of the second plate 52 and the extension line of the third plate 53 form an angle β, and the range of α is 10°≤β≤60°. Specifically, the above angle can be 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60° and other angles. The size of the angle will affect the size of the opening of the protective shell 50 away from the second surface 12. If the angle is small (less than 10°), it may cause the acquisition module 20 to detect fewer samples, affecting the detection accuracy of the acquisition module 20. If the angle is large, more samples will enter the protective shell 50, affecting the service life of the acquisition module 20. Preferably, the angle β in the present invention is preferably 20° to ensure the detection accuracy of the acquisition module 20.

[0061] See also Fig.10 , in some implementations, the signal processing module 30 includes: an amplifier 31, a filter 32;

[0062] The amplifier 31 is electrically connected to the PCB board 21 , the filter 32 is electrically connected to the amplifier 31 , the amplifier 31 is disposed on a side wall of the housing 10 , and the filter 32 is disposed on one side of the housing 10 .

[0063] It can be understood that the signal processing module 30 includes an amplifier 31 and a filter 32. The amplifier 31 can be set on the side wall of the shell 10. In order to ensure the optimization effect of the filter 32, the filter 32 is set on the side of the shell 10 close to the transmission module 40; the signal output by the acquisition module 20 cannot be directly received and used. Therefore, it is necessary to amplify the signal output by the acquisition module 20 so that the signal output by the sensor can be effectively transmitted. The amplified signal contains a large amount of interference signals. When the amplified signal is transmitted to the filter 32, the filter 32 processes the noise in the signal and filters out the noise, so that the output signal is only the required signal, reducing the impact of the coal mine environment on the data acquisition and transmission process, thereby improving data processing efficiency and data quality.

[0064] See also Figure 5 and Figure 6 In some embodiments, a support assembly 60 is further included, wherein the support assembly 60 includes a support plate 61, a support rod 62 and a reinforcing rib 63, wherein the support rod 62 is disposed on the support plate 61, and the axis of the support rod 62 intersects perpendicularly with the axis of the support plate 61, and the reinforcing rib 63 has a third surface 631 and a fourth surface 632, wherein the third surface 631 is connected to the support plate 61, and the fourth surface 632 is connected to the support rod 62; and a connecting hole is provided on the support rod 62.

[0065] It can be understood that the support assembly 60 is used to support the present device. Specifically, the support assembly 60 includes a support plate 61, a support rod 62 and a reinforcing rib 63. The support rod 62 is arranged on the support plate 61, and the support rod 62 is vertically arranged on the support plate 61 (the axis of the support rod 62 intersects with the axis of the support plate 61).

The reinforcing rib 63 includes a third surface 631 and a fourth surface 632, wherein the third surface 631 is the bottom surface of the reinforcing rib 63, the third surface 631 is connected to the support plate 61, and the fourth surface 632 is the side surface of the reinforcing rib 63, and the reinforcing rib 63 is connected to the support rod 62.

The fixing portion 72 is mainly used to fix the interface circuit 41 and the spare interface circuit 42. The fixing portion 72 protrudes and is inclined from the bottom wall of the housing 10, so as to facilitate the connection of the interface circuit 41 and the spare interface circuit 42 with the cable; a through hole is arranged on the connecting portion 71.
