[0024] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0025] like Figure 1 and Figure 2As shown in the figure, this disclosure proposes a coal mine underground sensing module with ranging function, including: a housing 1, an environmental parameter detection module 2, a ranging module 3, and a control module 4. The housing 1 is installed in the roadway, the environmental parameter detection module 2 is installed at the bottom of the housing 1, and the environmental parameter detection module 2 is used to detect the environmental parameters in the roadway. The ranging module 3 is installed on the housing 1, and the ranging module 3 is used to detect the distance from the environmental parameter detection module 2 to the roadway roof and the distance from the environmental parameter detection module 2 to the roadway sidewall. The control module 4 is installed in the housing 1, and the signal input terminal of the control module 4 is connected to the signal output terminal of the environmental parameter detection module 2 and the signal output terminal of the ranging module 3, respectively.

[0026] Understandably, since the environmental parameter detection module 2 is located at the bottom of the housing 1, and the signal input terminal of the control module 4 is connected to the signal output terminal of the environmental parameter detection module 2, the control module 4 can use the environmental parameter detection module 2 to obtain the environmental parameters in the tunnel. Furthermore, since the ranging module 3 is located on the housing 1, and the signal input terminal of the control module 4 is connected to the signal output terminal of the ranging module 3, the control module 4 can use the ranging module 3 to obtain the distance from the environmental parameter detection module 2 to the tunnel roof and the distance from the environmental parameter detection module 2 to the tunnel sidewall.

[0027] By using the ranging module 3 to detect the distances from the environmental parameter detection module 2 to the roadway roof and from the roadway sidewall, the control module 4 can monitor the position of the environmental parameter detection module 2 based on the distances detected by the ranging module 3. This ensures that the distances from the environmental parameter detection module 2 to the roadway roof and from the roadway sidewall meet relevant requirements. This ensures that the environmental parameter detection module 2 is in an effective detection position, allowing the collected parameters to reflect the actual underground environment, thereby guaranteeing high safety and construction efficiency in underground operations.

[0028] It should be noted that, according to relevant standards, the environmental parameter detection module 2 should be vertically suspended, and the distance between the environmental parameter detection module 2 and the roadway roof should not exceed 300mm, and the distance between the environmental parameter detection module 2 and the roadway sidewall should not be less than 200mm. Therefore, by utilizing the detection of the environmental parameter detection module 2, the control module 4 can perform relevant actions (such as alarms) when the distance between the environmental parameter detection module 2 and the roadway roof is greater than 300mm and / or the distance between the environmental parameter detection module 2 and the roadway sidewall is less than 200mm, so as to achieve precise control of the position of the environmental parameter detection module 2, thereby realizing accurate collection of underground environmental parameters.

[0029] The housing 1 is used to support the environmental parameter detection module 2, the ranging module 3, the control module 4, etc. The specific type of housing 1 can be set according to actual needs and there are no restrictions. For example, housing 1 can be close to a cuboid box structure. Housing 1 is vertically suspended on the roof of the tunnel using brackets, etc.

[0030] The environmental parameter detection module 2 is used to detect environmental parameters in the tunnel, such as gas concentration and temperature. The specific type of the environmental parameter detection module 2 can be set according to actual needs and there are no restrictions on it.

[0031] The ranging module 3 is used to detect the distance from the environmental parameter detection module 2 to the tunnel roof and the distance from the environmental parameter detection module 2 to the tunnel sidewall. The specific type of the ranging module 3 can be set according to actual needs and there are no restrictions on it.

[0032] The control module 4 is used to obtain the environmental parameters in the tunnel using the environmental parameter detection module 2, and to obtain the distance parameters of the environmental parameter detection module 2 in the tunnel using the ranging module 3. The specific type of the control module 4 can be set according to actual needs and is not limited thereto. For example, the control module 4 can integrate the circuit board of the control chip, which is arranged inside the housing 1.

[0033] like Figure 1 As shown, in some embodiments, the ranging module 3 includes: a first ranging unit 31, a second ranging unit 32, and a third ranging unit 33. The first ranging unit 31 is disposed on the top of the housing 1, and the signal output terminal of the first ranging unit 31 is connected to the signal input terminal of the control module 4. The first ranging unit 31 is used to detect the distance from the environmental parameter detection module 2 to the top of the tunnel. The second ranging unit 32 is disposed on the first side of the housing 1, and the signal output terminal of the second ranging unit 32 is connected to the signal input terminal of the control module 4. The second ranging unit 32 is used to detect the distance from the environmental parameter detection module 2 to the first sidewall of the tunnel. The third ranging unit 33 is disposed on the second side of the housing 1, and the signal output terminal of the third ranging unit 33 is connected to the signal input terminal of the control module 4. The third ranging unit 33 is used to detect the distance from the environmental parameter detection module 2 to the second sidewall of the tunnel.

[0034] Understandably, since the first ranging unit 31 is located on the top of the housing 1 and its signal output terminal is connected to the signal input terminal of the control module 4, the control module 4 can use the first ranging unit 31 to obtain the distance from the environmental parameter detection module 2 to the tunnel roof. Since the second ranging unit 32 is located on the first side of the housing 1 and its signal output terminal is connected to the signal input terminal of the control module 4, the control module 4 can use the second ranging unit 32 to obtain the distance from the environmental parameter detection module 2 to the first sidewall of the tunnel. Since the third ranging unit 33 is located on the second side of the housing 1 and its signal output terminal is connected to the signal input terminal of the control module 4, the control module 4 can use the third ranging unit 33 to obtain the distance from the environmental parameter detection module 2 to the second sidewall of the tunnel.

[0035] It should be noted that the first ranging unit 31 is used to detect the distance from the environmental parameter detection module 2 to the tunnel roof. The first ranging unit 31 is arranged on the top of the housing 1, while the environmental parameter detection module 2 is arranged on the bottom of the housing 1. This means that the distance from the environmental parameter detection module 2 to the tunnel roof detected by the first ranging unit 31 needs to be supplemented with the distance between the first ranging unit 31 and the environmental parameter detection module 2.

[0036] Specifically, the distance from the environmental parameter detection module 2 to the tunnel roof is L, and the distance from the first ranging unit 31 to the tunnel roof (actual detection distance) is l2. Then L = l2 + h ≤ 300 mm.

[0037] The second ranging unit 32 is used to detect the distance from the environmental parameter detection module 2 to the first sidewall of the tunnel, and the third ranging unit 33 is used to detect the distance from the environmental parameter detection module 2 to the second sidewall of the tunnel. The second ranging unit 32 and the first sidewall of the tunnel are arranged opposite to each other, and the third ranging unit 33 and the second sidewall of the tunnel are arranged opposite to each other.

[0038] Specifically, the distance from the environmental parameter detection module 2 to the sidewall of the tunnel (the distance from the second ranging unit 32 to the first sidewall of the tunnel and the distance from the third ranging unit 33 to the roof of the tunnel) is denoted as l1, and then l1≥200mm.

[0039] The specific types of the first ranging unit 31, the second ranging unit 32, and the third ranging unit 33 can be set according to actual needs, and there are no restrictions on this. For example, the first ranging unit 31, the second ranging unit 32, and the third ranging unit 33 can be ultrasonic ranging sensors, laser ranging sensors, etc.

[0040] Since the distance between the first and second sidewalls of the tunnel is relatively large, when the sensing module is close to the first sidewall, only the distance from the environmental parameter detection module 2 to the first sidewall of the tunnel is collected by the second ranging unit 32, without considering the distance signal collected by the third ranging unit 33. Conversely, when the sensing module is close to the second sidewall, only the distance from the environmental parameter detection module 2 to the second sidewall of the tunnel is collected by the third ranging unit 33, without considering the distance signal collected by the second ranging unit 32.

[0041] like Figure 2 As shown, in some embodiments, the ranging module 3 further includes: a concentration detection unit 5, which is disposed on the housing 1, and the signal output terminal of the concentration detection unit 5 is connected to the signal input terminal of the control module 4. The concentration detection unit 5 is used to detect the dust concentration in the tunnel; the first ranging unit 31, the second ranging unit 32 and the third ranging unit 33 respectively include: an ultrasonic sensor and a laser sensor, and the signal output terminals of the ultrasonic sensor and the laser sensor are respectively connected to the signal input terminal of the control module 4.

[0042] It is understandable that, since the concentration detection unit 5 is mounted on the housing 1 and the signal output terminal of the concentration detection unit 5 is connected to the signal input terminal of the control module 4, the control module 4 can use the concentration detection unit 5 to obtain the dust concentration in the roadway; since the signal output terminals of the ultrasonic sensor and the laser sensor are respectively connected to the signal input terminal of the control module 4, the control module 4 can use the ultrasonic sensor and / or the laser sensor to obtain the distance parameter of the environmental parameter detection module 2 in the roadway.

[0043] Among them, the control module 4 can switch between ultrasonic sensors and laser sensors according to the dust concentration in the tunnel. For example, when the dust concentration is ≤50mg / m³, the control module 4 can switch between ultrasonic sensors and laser sensors. 3 When the laser sensor is used, the control module 4 collects the distance signal; otherwise, the control module 4 collects the distance signal using the ultrasonic sensor.

[0044] It should be noted that the control module 4 can simultaneously use both the laser sensor and the ultrasonic sensor to acquire distance signals. The two sensors are redundantly designed and mutually calibrated.

[0045] The concentration detection unit 5 is used to detect the dust concentration in the roadway. The specific type of the concentration detection unit 5 can be set according to actual needs and there is no limitation. For example, the concentration detection unit 5 can be a dust concentration sensor.

[0046] like Figure 2As shown, in some embodiments, the sensing module further includes a humidity detection module 6, which is disposed on the housing 1, and the signal output terminal of the humidity detection module 6 is connected to the signal input terminal of the control module 4. The humidity detection module 6 is used to detect the humidity in the tunnel.

[0047] It is understandable that since the humidity detection module 6 is mounted on the housing 1 and the signal output terminal of the humidity detection module 6 is connected to the signal input terminal of the control module 4, the control module 4 can use the humidity detection module 6 to obtain the humidity in the tunnel, thereby facilitating the compensation of distance parameters based on the humidity in the tunnel, and thus ensuring the high detection accuracy of the sensing module.

[0048] It should be noted that the humidity detection module 6 is used to detect the humidity in the tunnel. The specific type of humidity detection module 6 can be set according to actual needs and there are no restrictions on it. For example, the humidity detection module 6 can be a humidity sensor.

[0049] In some embodiments, the environmental parameter detection module 2 includes a temperature sensor, which is disposed at the bottom of the housing 1 and the signal output terminal of the temperature sensor is connected to the signal input terminal of the control module 4. The temperature sensor is used to detect the temperature in the tunnel.

[0050] Understandably, since the temperature sensor is located at the bottom of the housing 1 and the signal output terminal of the temperature sensor is connected to the signal input terminal of the control module 4, the control module 4 can use the temperature sensor to obtain the temperature inside the roadway, thereby realizing the monitoring of the roadway temperature and ensuring safe operation underground.

[0051] In addition, based on the temperature detected by the temperature sensor in the tunnel, the control module 4 can also perform temperature compensation for the distance parameter according to the temperature, thereby ensuring high detection accuracy of the sensing module.

[0052] It should be noted that the temperature sensor is used to detect the temperature inside the tunnel, and the specific type of temperature sensor can be set according to actual needs, without any restrictions.

[0053] In some embodiments, the environmental parameter detection module 2 includes a methane sensor, which is disposed at the bottom of the housing 1 and the signal output terminal of the methane sensor is connected to the signal input terminal of the control module 4. The methane sensor is used to detect the methane concentration in the tunnel.

[0054] Understandably, since the methane sensor is located at the bottom of the housing 1 and its signal output terminal is connected to the signal input terminal of the control module 4, the control module 4 can use the methane sensor to obtain the methane concentration in the roadway, thereby realizing the monitoring of methane in the roadway and ensuring safe operation underground.

[0055] It should be noted that the methane sensor is used to detect the methane concentration in the tunnel. The specific type of methane sensor can be set according to actual needs, and there are no restrictions on it.

[0056] In some embodiments, the environmental parameter detection module 2 includes a carbon monoxide sensor, which is disposed at the bottom of the housing 1 and the signal output terminal of the carbon monoxide sensor is connected to the signal input terminal of the control module 4. The carbon monoxide sensor is used to detect the carbon monoxide concentration in the tunnel.

[0057] Understandably, since the carbon monoxide sensor is located at the bottom of the housing 1 and the signal output terminal of the carbon monoxide sensor is connected to the signal input terminal of the control module 4, the control module 4 can use the carbon monoxide sensor to obtain the carbon monoxide concentration in the roadway, thereby realizing the monitoring of carbon monoxide in the roadway and ensuring safe operation underground.

[0058] It should be noted that the carbon monoxide sensor is used to detect the carbon monoxide concentration in the tunnel. The specific type of carbon monoxide sensor can be set according to actual needs, and there are no restrictions on it.

[0059] like Figure 1 and Figure 2 As shown, in some embodiments, the sensing module further includes an alarm module 7, which is disposed on the housing 1, and the signal input terminal of the alarm module 7 is connected to the signal output terminal of the control module 4.

[0060] It is understandable that since the alarm module 7 is mounted on the housing 1 and the signal input terminal of the alarm module 7 is connected to the signal output terminal of the control module 4, the control module 4 can control the alarm module 7 to issue alarm information.

[0061] For example, when the distance between the environmental parameter detection module 2 and the tunnel roof is greater than 300mm, and / or the distance between the environmental parameter detection module 2 and the tunnel sidewall is less than 200mm, the control module 4 controls the alarm module 7 to issue an alarm message, thereby prompting the operator to readjust the position of the environmental parameter detection module 2, and thus achieving precise distance control.

[0062] It should be noted that the alarm module 7 is used to issue alarm information. The specific type of the alarm module 7 can be set according to actual needs and there are no restrictions on it. For example, the alarm module 7 can be an audible / visual alarm.

[0063] like Figure 1 and Figure 2 As shown, in some embodiments, the sensing module further includes a display module 8, which is disposed on the housing 1, and the signal input terminal of the display module 8 is connected to the signal output terminal of the control module 4.

[0064] It is understandable that, since the display module 8 is mounted on the housing 1 and the signal input terminal of the display module 8 is connected to the signal output terminal of the control module 4, the control module 4 can use the display module 8 to display the detection data.

[0065] For example, the display module 8 can display the distance from the environmental parameter detection module 2 to the tunnel roof, the distance from the environmental parameter detection module 2 to the first sidewall of the tunnel, the distance from the environmental parameter detection module 2 to the second sidewall of the tunnel, and environmental parameters within the tunnel.

[0066] like Figure 2 As shown, in some embodiments, the sensing module further includes a wireless communication module 9, which is disposed inside the housing 1, and the communication terminal of the wireless communication module 9 is connected to the communication terminal of the control module 4. The wireless communication module 9 is used for wireless communication between the control module 4 and the monitoring system.

[0067] It is understandable that since the wireless communication module 9 is located inside the housing 1 and the communication end of the wireless communication module 9 is connected to the communication end of the control module 4, the control module 4 and the monitoring system can use the wireless communication module 9 to achieve wireless communication, thereby meeting the remote monitoring requirements.

[0068] It should be noted that the monitoring system can be a ground-based remote monitoring system, or it can include mobile devices such as mobile phones, tablets, and remote controls that can remotely control module 4; there are no restrictions on this.

[0069] In the description of this disclosure, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this disclosure, unless otherwise stated, "a plurality of" means two or more.
