Description

Technical Field

[0001] This disclosure relates to the field of coal mining technology, and in particular to a method, apparatus and electronic equipment for detecting the upward and downward movement of a transport aircraft. Background Technology

[0002] The coal seams in fully mechanized coal mining faces are all naturally formed, with uneven thickness distribution and a certain slope. During coal mining, fully mechanized mining equipment such as scraper conveyors, under the influence of gravity, thrust, and other factors, will generate upward or downward forces in the inclined direction of the coal mining face. This can cause misalignment at the head or tail of the scraper conveyor, resulting in upward or downward movement, which can easily lead to accidents.

[0003] Scraper conveyors possess advantages such as large transport capacity, low operating resistance, minimal coal crushing effect, low noise, and high safety and reliability. They are the most widely used continuous transport equipment in fully mechanized mining systems, serving multiple roles including the coal mining machine's running track, coal transport, and assisting hydraulic supports in moving and pushing the conveyor. Therefore, detecting upward and downward movement of scraper conveyors is crucial for the normal operation of other production processes in the fully mechanized mining face and for preventing accidents caused by upward and downward movement of the scraper conveyor. Summary of the Invention

[0004] This disclosure aims to at least partially address one of the technical problems in the aforementioned technologies.

[0005] Therefore, this disclosure proposes a method for detecting the upward and downward movement of a transport aircraft, so as to detect the upward and downward movement of the transport aircraft, thereby ensuring the normal operation of other production processes in the fully mechanized mining face and avoiding accidents caused by the upward and downward movement of the transport aircraft.

[0006] The first aspect of this disclosure provides a method for detecting upward and downward movement of a conveyor, comprising: acquiring a reference mileage when a coal mining machine passes a hydraulic support at the second end of a fully mechanized mining face as it travels along the conveyor from the first end to the second end; acquiring a real-time mileage when the coal mining machine passes a hydraulic support at the second end as it travels along the conveyor from the first end to the second end; and determining, based on the reference mileage and the real-time mileage, whether upward and downward movement has occurred at the end of the conveyor located at the second end.

[0007] The method for detecting upward and downward movement of a conveyor in this embodiment of the present disclosure obtains the reference mileage of the coal mining machine when it passes the hydraulic support at the second end of the fully mechanized mining face as it travels along the first end to the second end, and obtains the real-time mileage of the coal mining machine when it passes the hydraulic support at the second end as it travels along the first end to the second end of the conveyor. Based on the reference mileage and the real-time mileage, it determines whether the end of the conveyor located at the second end has experienced upward and downward movement. This method can detect upward and downward movement of the conveyor, thereby ensuring the normal operation of other production processes in the fully mechanized mining face and preventing accidents caused by upward and downward movement of the conveyor.

[0008] A second aspect of this disclosure provides a detection device for a conveyor that experiences upward or downward movement, comprising: a first acquisition module for acquiring a reference mileage when a coal mining machine passes a hydraulic support at the second end of a fully mechanized mining face as it travels along the conveyor from the first end to the second end; a second acquisition module for acquiring a real-time mileage when the coal mining machine passes a hydraulic support at the second end as it travels along the conveyor from the first end to the second end; and a first determination module for determining, based on the reference mileage and the real-time mileage, whether upward or downward movement has occurred at the end of the conveyor located at the second end.

[0009] The conveyor uphill / downhill detection device of this embodiment obtains the reference mileage of the coal mining machine when it passes the hydraulic support at the second end of the fully mechanized mining face as it travels along the first end to the second end of the conveyor, and obtains the real-time mileage of the coal mining machine when it passes the hydraulic support at the second end of the conveyor. Based on the reference mileage and the real-time mileage, it determines whether the end of the conveyor located at the second end has experienced uphill / downhill movement. This device can detect uphill / downhill movement of the conveyor, thereby ensuring the normal operation of other production processes in the fully mechanized mining face and preventing accidents caused by uphill / downhill movement of the conveyor.

[0010] A third aspect of this disclosure provides an electronic device, comprising: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to perform the method described in the first aspect of this disclosure.

[0011] A fourth aspect of this disclosure provides a non-transitory computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the method described in the first aspect of this disclosure.

[0012] A fifth aspect of this disclosure provides a computer program product including a computer program that, when executed by a processor, implements the method described in the first aspect of this disclosure.

[0013] Additional aspects and advantages of this disclosure will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this disclosure. Attached Figure Description

[0021] 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 intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0022] This disclosure proposes a method, device, and electronic equipment for detecting the upward and downward movement of a transport aircraft, which can detect the upward and downward movement of the transport aircraft, thereby ensuring the normal operation of other production processes in the fully mechanized mining face and avoiding accidents caused by the upward and downward movement of the transport aircraft.

[0023] The following description, with reference to the accompanying drawings, describes a method, apparatus, and electronic device for detecting a transport aircraft sliding uphill.

[0024] Figure 1 This is a schematic flowchart illustrating a method for detecting the upward and downward movement of a transport aircraft, provided in an embodiment of this disclosure.

[0025] It should be noted that the method for detecting the upward and downward movement of a transport aircraft provided in this disclosure can be executed by a device for detecting the upward and downward movement of a transport aircraft, which can be simply referred to as a detection device. The detection device can be an electronic device, or it can be configured within an electronic device to detect the upward and downward movement of the transport aircraft. The electronic device can be any device capable of data processing, such as a personal computer or a smartphone; this disclosure does not impose any limitations on this.

[0026] like Figure 1 As shown, the detection method for the transport aircraft's upward and downward movement may include:

[0027] Step 101: Obtain the reference mileage of the coal mining machine when it passes the hydraulic support at the second end of the longwall mining face as it travels along the conveyor from the first end to the second end of the longwall mining face.

[0028] Among them, the transport aircraft can be a scraper transport aircraft.

[0029] Understandably, under normal circumstances, the conveyor extends along the length of the fully mechanized mining face, with its two ends located at opposite ends of the face. Multiple hydraulic supports are arranged sequentially along the length of the face, and each hydraulic support is rigidly connected to the conveyor. The coal mining machine is mounted on the conveyor and can run along the length of the fully mechanized mining face until it cuts through the coal face to achieve coal mining. Since the hydraulic supports are arranged sequentially along the fully mechanized mining face, the coal mining machine will pass over each hydraulic support during its operation. It should be noted that in this embodiment, the coal mining machine passing over a hydraulic support can be understood as the line connecting a point on the coal mining machine and a point on that hydraulic support being perpendicular to the coal mining machine's trajectory.

[0030] In the absence of upward or downward movement of the conveyor, it can be assumed that when the coal mining machine is running from the tail of the conveyor towards the head, it cuts through the coal wall when it reaches the head position, and when the coal mining machine is running from the head of the conveyor towards the tail, it cuts through the coal wall when it reaches the tail position.

[0031] In this context, any one end of the longwall mining face can be referred to as the first end, and the other end of the longwall mining face can be referred to as the second end.

[0032] The transport aircraft includes a head and a tail section. In this embodiment, the head of the transport aircraft can be located at the first end of the fully mechanized mining face, and correspondingly, the tail of the transport aircraft can be located at the second end of the fully mechanized mining face. Alternatively, the tail of the transport aircraft can be located at the first end of the fully mechanized mining face, and correspondingly, the head of the transport aircraft can be located at the second end of the fully mechanized mining face.

[0033] In this embodiment of the present disclosure, the coal mining machine can be pre-controlled to run along the first end to the second end of the fully mechanized mining face on the conveyor without the conveyor sliding up or down, until it cuts through the coal wall, and the mileage when the coal mining machine passes the hydraulic support at the second end is recorded, and the mileage is used as the baseline mileage.

[0034] The hydraulic support at the second end refers to the hydraulic support that the coal mining machine passes near the second end as it travels along the longwall face from the first end to the second end on the conveyor until it cuts through the coal face. The number of hydraulic supports at the second end can be one or more; this disclosure does not limit this.

[0035] The reference mileage is calculated from a preset position point, which is referred to as the zero point in this embodiment. In other words, the reference mileage is the distance traveled by the coal mining machine on the conveyor from the preset zero point to the position where the coal mining machine passes the hydraulic support at the second end, assuming the conveyor does not experience any upward or downward movement.

[0036] The mileage zero point can be set as needed. For example, if the first end is the tail end of the conveyor and the second end is the head end, meaning the coal mining machine is moving from the tail to the head on the conveyor, the tail position or the first position can be set as the mileage zero point. The first position can be any position between the tail position and the position where the coal mining machine passes the hydraulic support at the second end. Alternatively, if the first end is the head end of the conveyor and the second end is the tail end, meaning the coal mining machine is moving from the head to the tail on the conveyor, the head position or the second position can be set as the mileage zero point. The second position can be any position between the head position and the position where the coal mining machine passes the hydraulic support at the second end.

[0037] Step 102: Obtain the real-time mileage of the coal mining machine as it travels along the conveyor from the first end to the second end, passing the hydraulic support at the second end.

[0038] In this embodiment of the disclosure, in order to detect whether the conveyor has slid up or down during actual fully mechanized mining production, the coal mining machine can be controlled to run along the first end to the second end of the fully mechanized mining face on the conveyor, and the mileage traveled by the coal mining machine when passing the hydraulic support at the second end can be recorded. This mileage is referred to as the real-time mileage. The hydraulic support at the second end in step 102 and step 101 is the same hydraulic support.

[0039] The real-time mileage is calculated from a preset mileage zero point, and the mileage zero point of the real-time mileage is the same as the mileage zero point of the base mileage.

[0040] In this embodiment of the disclosure, the description of step 102 can be referred to the description of step 101, as the specific implementation process and principle are the same, and will not be repeated here. The difference between step 102 and step 101 is that the baseline mileage is collected when the transport aircraft has not experienced any upward or downward movement, while the real-time mileage is collected when detecting whether the transport aircraft has experienced any upward or downward movement.

[0041] Step 103: Based on the baseline mileage and the real-time mileage, determine whether the end of the transport aircraft located at the second end has experienced upward or downward movement.

[0042] It is understandable that when the conveyor experiences an upward or downward movement at one end of the second end, the real-time mileage of the coal mining machine traveling along the first end of the fully mechanized mining face towards the second end on the conveyor, passing the hydraulic support at the second end, is different from the baseline mileage of the coal mining machine traveling along the first end of the fully mechanized mining face towards the second end on the conveyor when the conveyor does not experience an upward or downward movement at one end of the second end, passing the hydraulic support at the second end.

[0043] For example, suppose the conveyor head is located at the second end of the longwall mining face, and the conveyor tail is located at the first end. Assuming the conveyor head does not experience upward or downward movement, the coal mining machine, while traveling along the conveyor tail towards the head, cuts through the coal wall at a hydraulic support at the second end. At this point, the coal mining machine's baseline travel distance is 100 meters. In actual longwall mining production, if the conveyor head experiences upward movement, the coal mining machine, while traveling along the conveyor tail towards the head, will not reach the conveyor head position before passing the hydraulic support and cutting through the coal wall, meaning the real-time travel distance will decrease. Conversely, if the conveyor head experiences downward movement, the coal mining machine, while traveling along the conveyor tail towards the head, will not reach the hydraulic support and cut through the coal wall before reaching the conveyor head position, meaning the real-time travel distance will increase.

[0044] Therefore, in this embodiment, it can be determined whether the end of the conveyor at the second end has experienced upward or downward movement based on whether the reference mileage and real-time mileage are the same when the coal mining machine travels along the conveyor from the first end to the second end and passes the same hydraulic support. Specifically, if the reference mileage and real-time mileage are the same when the coal mining machine passes the same hydraulic support, it can be determined that the end of the conveyor at the second end has not experienced upward or downward movement; if the reference mileage and real-time mileage are different, it can be determined that the end of the conveyor at the second end has experienced upward or downward movement. Specifically, upward movement occurs when the conveyor head exceeds the fully mechanized mining face area, and downward movement occurs when the conveyor head moves into the fully mechanized mining face area; upward movement occurs when the conveyor tail moves into the fully mechanized mining face area, and downward movement occurs when the conveyor tail exceeds the fully mechanized mining face area.

[0045] In summary, the method for detecting upward and downward movement of a conveyor provided in this embodiment of the present disclosure obtains the reference mileage of the coal mining machine when it passes the hydraulic support at the second end of the fully mechanized mining face as it travels along the first end to the second end, and obtains the real-time mileage of the coal mining machine when it passes the hydraulic support at the second end as it travels along the first end to the second end of the conveyor. Based on the reference mileage and the real-time mileage, it determines whether the end of the conveyor located at the second end has experienced upward and downward movement. This method can detect upward and downward movement of the conveyor, thereby ensuring the normal operation of other production processes in the fully mechanized mining face and preventing accidents caused by upward and downward movement of the conveyor.

[0046] The following is combined Figure 2 This disclosure further explains the detection method for the upward and downward movement of transport aircraft proposed in this publication.

[0047] Figure 2 This is a schematic flowchart illustrating a method for detecting the upward and downward movement of a transport aircraft, provided in an embodiment of this disclosure.

[0048] like Figure 2 As shown, the detection method for the transport aircraft's upward and downward movement may include the following steps:

[0049] Step 201: Obtain the reference mileage of the coal mining machine when it passes the hydraulic support at the second end during the process of the coal mining machine running along the first end to the second end of the fully mechanized mining face on the conveyor. There are multiple hydraulic supports at the second end.

[0050] Step 202: Obtain the real-time mileage of the coal mining machine as it travels along the conveyor from the first end to the second end, passing the hydraulic support at the second end.

[0051] The specific implementation process and principle of steps 201-202 can be found in the descriptions of other embodiments, and will not be repeated here.

[0052] In the embodiments of this disclosure, the real-time driving mileage and the baseline driving mileage can be obtained by an odometer installed on the coal mining machine.

[0053] The odometer can be the existing encoder speed measuring mechanism on the coal mining machine. This encoder speed measuring mechanism can calculate the actual travel speed of the coal mining machine by combining the transmission unit of the traction motor and the size of the traveling gear of the coal mining machine, and accumulate the number of revolutions of the traveling gear under ideal conditions, thereby calculating the travel distance of the coal mining machine during operation.

[0054] In addition, the coal mining machine is equipped with an infrared transmitter, which can emit infrared signals in real time along a preset direction during the operation of the coal mining machine. Each hydraulic support is equipped with an infrared receiver. In this embodiment, when the infrared receiver installed on a hydraulic support at the second end receives an infrared signal, it can be determined that the coal mining machine has passed that hydraulic support. The preset direction can be, for example, a direction perpendicular to the travel trajectory of the coal mining machine.

[0055] As one possible implementation, each hydraulic support is equipped with a controller that, during the movement of the coal mining machine on the conveyor along the longwall face from the first end to the second end, such as... Figure 3 As shown, the infrared transmitter 'a' installed on the coal mining machine can emit infrared signals in real time in a direction perpendicular to the length of the fully mechanized mining face. When the infrared receiver on a hydraulic support A receives the infrared signal, the controller installed on that hydraulic support A can determine that the coal mining machine has passed the hydraulic support and record the current time. Furthermore, the controller can send the time when the coal mining machine passes the hydraulic support A and the identifier of the hydraulic support A it has passed to the detection device.

[0056] Furthermore, the odometer installed on the coal mining machine can record the mileage of the coal mining machine in real time and send it to the detection device. Thus, the detection device can obtain the mileage of the coal mining machine when it passes the hydraulic support A based on the time when the coal mining machine passes the hydraulic support A.

[0057] Therefore, by using the existing infrared receiver on the hydraulic support, the existing infrared transmitter on the coal mining machine, and the odometer, the reference mileage and real-time mileage of the coal mining machine when it passes the hydraulic support at the second end during its operation along the longwall face from the first end to the second end on the conveyor can be obtained. Based on the reference mileage and real-time mileage, it can be determined whether the conveyor has experienced upward or downward movement. The method is simple and reliable, and no additional sensors are required, saving the cost of detecting upward or downward movement of the conveyor.

[0058] Step 203: For the same hydraulic support at the second end, obtain the difference between the corresponding first reference mileage and the first real-time mileage.

[0059] Step 204: Obtain the average of multiple differences.

[0060] Step 205: With the average value being zero, determine that the end of the transport aircraft located at the second end has not experienced an upward or downward movement.

[0061] Step 206: If the average value is not zero, determine that the end of the transport aircraft located at the second end has experienced an upward or downward movement.

[0062] In this embodiment, the number of hydraulic supports at the second end can be set to one. Correspondingly, the real-time mileage of the coal mining machine includes the second real-time mileage when the coal mining machine passes a hydraulic support at the second end during its movement from the first end to the second end of the fully mechanized mining face; the reference mileage of the coal mining machine includes the second reference mileage when the coal mining machine passes a hydraulic support at the second end during its movement from the first end to the second end of the fully mechanized mining face. In this embodiment, the difference between the second reference mileage and the second real-time mileage can be obtained. If the difference is zero, it is determined that the end of the conveyor at the second end has not experienced upward or downward movement; if the difference is not zero, it is determined that the end of the conveyor at the second end has experienced upward or downward movement.

[0063] In this embodiment, to avoid poor stability of individual data, the number of hydraulic supports at the second end can be set to multiple. Correspondingly, the real-time mileage of the coal mining machine includes the first real-time mileage when the coal mining machine passes each hydraulic support at the second end during its movement from the first end to the second end; the reference mileage of the coal mining machine includes the first reference mileage when the coal mining machine passes each hydraulic support at the second end during its movement from the first end to the second end. In this embodiment, for the same hydraulic support at the second end, the difference between the corresponding first reference mileage and the first real-time mileage can be obtained, and the average of multiple differences can be obtained. If the average is zero, it is determined that the end of the conveyor located at the second end has not experienced upward or downward movement; if the average is not zero, it is determined that the end of the conveyor located at the second end has experienced upward or downward movement. This improves the reliability of the detection results for upward or downward movement of the conveyor.

[0064] In this embodiment of the disclosure, when the first end is the tail section of the transport aircraft and the second end is the nose section of the transport aircraft, after determining that the nose section of the transport aircraft has experienced an upward or downward movement, the type of nose displacement and the amount of nose displacement relative to its original position can be determined as follows: if the average value is greater than zero, the type of nose displacement is determined to be an upward movement, and the absolute value of the average value is determined as the amount of nose displacement relative to its original position; if the average value is less than zero, the type of nose displacement is determined to be a downward movement, and the absolute value of the average value is determined as the amount of nose displacement relative to its original position. Wherein, for the same hydraulic support at the second end, the difference between the corresponding first reference mileage and the first real-time mileage is the first reference mileage minus the first real-time mileage.

[0065] The original position of the nose is the position when the nose has not slid up or down.

[0066] In this embodiment of the disclosure, when the first end is the end where the nose of the transport aircraft is located and the second end is the end where the tail of the transport aircraft is located, after determining that the tail end of the transport aircraft, located at the second end, experiences an upward or downward movement, the type of tail offset and the amount of tail offset relative to the original tail position can be determined in the following ways: if the average value is greater than zero, the type of tail offset is determined to be downward movement, and the absolute value of the average value is determined to be the amount of tail offset relative to the original tail position; if the average value is less than zero, the type of tail offset is determined to be upward movement, and the absolute value of the average value is determined to be the amount of tail offset relative to the original tail position. Wherein, for the same hydraulic support at the second end, the difference between the corresponding first reference mileage and the first real-time mileage is the first reference mileage minus the first real-time mileage.

[0067] The original position of the tail is the position where the tail was before it began to rise or slide.

[0068] The following is combined Figure 3 and Figure 4 Taking the first end as the tail section of the transport aircraft and the second end as the nose section as an example, this paper explains the process of determining whether the nose section of the transport aircraft has experienced upward or downward movement, and the type of nose section offset and the amount of offset relative to its original position when upward or downward movement occurs. Figure 3 This is a schematic diagram of a transport aircraft when its nose and tail have not slid upwards or downwards. Figure 4 This is a schematic diagram illustrating the upward movement of the conveyor head during actual fully mechanized mining operations. In this embodiment, the zero-mileage point is used as the location of the coal mining machine when it passes the hydraulic support marked 60.

[0069] refer to Figure 3When the nose and tail of the transport aircraft do not swerve upwards or downwards, the position of the tail is as follows: Figure 3 As shown in O1, the location of the machine head is as follows: Figure 3 As shown in O2, the coal mining machine can be pre-controlled to run along the first end to the second end of the fully mechanized mining face (i.e., from the tail to the head) on the conveyor until it cuts through the coal wall when it passes the hydraulic support marked 4. The first reference travel distance when the coal mining machine passes each hydraulic support marked 4 to 10 can be obtained by using the infrared transmitter a installed on the coal mining machine, the encoder speed measuring mechanism, and the infrared receiver installed on the hydraulic support.

[0070] refer to Figure 4 In actual fully mechanized mining production, in order to detect whether the conveyor has slid up or down, the coal mining machine can be controlled to run on the conveyor along the first end to the second end of the fully mechanized mining face (i.e., from the tail to the head). The first real-time travel distance of the coal mining machine when passing each hydraulic support marked 4 to 10 can be obtained through the infrared transmitter a installed on the coal mining machine, the encoder speed measuring mechanism, and the infrared receiver installed on the hydraulic support.

[0071] Furthermore, for each hydraulic support marked 4 to 10, the detection device can obtain the difference between the corresponding first reference mileage and the first real-time mileage, and obtain the average value of multiple differences. Since the first real-time mileage is less than the first reference mileage when the coal mining machine passes each hydraulic support marked 4 to 10 in the case of upward movement of the conveyor head, the detection device will obtain a result with an average value greater than zero, thereby determining that the conveyor head has moved upward or downward. Based on the result with an average value greater than zero, the device determines that the offset type of the head is upward movement, and determines the absolute value of the average value as the offset of the head relative to its original position O2.

[0072] In summary, the conveyor uphill / downhill detection method provided in this embodiment of the present disclosure obtains the reference mileage of the coal mining machine as it travels along the first end to the second end of the fully mechanized mining face, passing the hydraulic supports at the second end. There are multiple hydraulic supports at the second end. The method also obtains the real-time mileage of the coal mining machine as it travels along the first end to the second end of the conveyor, passing the hydraulic supports at the second end. For the same hydraulic support at the second end, the method obtains the difference between the corresponding first reference mileage and the first real-time mileage. The method then obtains the average of multiple differences. If the average is zero, it determines that the end of the conveyor at the second end has not experienced uphill / downhill movement; if the average is not zero, it determines that the end of the conveyor at the second end has experienced uphill / downhill movement. This method can detect uphill / downhill movement of the conveyor, thereby ensuring the normal operation of other production processes at the fully mechanized mining face and preventing accidents caused by uphill / downhill movement of the conveyor.

[0073] To achieve the above embodiments, this disclosure also proposes a detection device for the upward and downward movement of a transport aircraft.

[0074] Figure 5 This is a schematic diagram of the structure of a detection device for a transport aircraft sliding uphill, provided in an embodiment of this disclosure.

[0075] like Figure 5 As shown, the detection device 500 for the transport aircraft sliding up and down includes: a first acquisition module 510, a second acquisition module 520, and a first determination module 530.

[0076] The first acquisition module 510 is used to acquire the reference mileage when the coal mining machine passes the hydraulic support at the second end during the process of the coal mining machine running along the first end to the second end of the fully mechanized mining face on the conveyor.

[0077] The second acquisition module 520 is used to acquire the real-time mileage of the coal mining machine when it passes the hydraulic support at the second end as it runs along the direction from the first end to the second end on the conveyor.

[0078] The first determining module 530 is used to determine whether the end of the transport aircraft located at the second end has experienced upward or downward movement based on the baseline mileage and the real-time mileage.

[0079] It should be noted that the transport aircraft uphill / downhill detection device 500 provided in this embodiment can execute the transport aircraft uphill / downhill detection method described in the foregoing embodiments. The transport aircraft uphill / downhill detection device 500 can be simply referred to as a detection device. The detection device can be an electronic device, or it can be configured within an electronic device to detect the uphill / downhill movement of the transport aircraft. The electronic device can be any device capable of data processing, such as a personal computer or smartphone; this disclosure does not impose any limitations on this.

[0080] As one possible implementation of this disclosure, the real-time driving mileage and the reference driving mileage are collected by the odometer installed on the coal mining machine; the coal mining machine is equipped with an infrared transmitter, which emits infrared signals in real time along a preset direction during the operation of the coal mining machine.

[0081] The transport aircraft swerve detection device 500 also includes:

[0082] The second determining module is used to determine that the coal mining machine has passed the hydraulic support at the second end when the infrared receiver installed on the hydraulic support at the second end receives the infrared signal.

[0083] As one possible implementation of this disclosure, the first end is the end where the tail of the conveyor is located, the second end is the end where the head of the conveyor is located, and the real-time mileage and the reference mileage of the coal mining machine are based on the position of the tail or the first position as the mileage zero point. The first position is any position between the position of the tail and the position where the coal mining machine is located when it passes the hydraulic support of the second end.

[0084] Alternatively, the first end is the end where the head of the conveyor is located, and the second end is the end where the tail of the conveyor is located. The real-time mileage and the reference mileage of the coal mining machine are based on the position of the head or the second position as the zero point of the mileage. The second position is any position between the position of the head and the position of the coal mining machine when it passes the hydraulic support at the second end.

[0085] As one possible implementation of this disclosure, the number of hydraulic supports at the second end is multiple; the real-time mileage of the coal mining machine includes the first real-time mileage when the coal mining machine passes each hydraulic support at the second end during its operation from the first end to the second end; the reference mileage of the coal mining machine includes the first reference mileage when the coal mining machine passes each hydraulic support at the second end during its operation from the first end to the second end.

[0086] The first determining module 530 is specifically used for:

[0087] For the same hydraulic support at the second end, obtain the difference between the corresponding first reference mileage and the first real-time mileage;

[0088] Get the average of multiple differences;

[0089] With the average value being zero, it was determined that the end of the transport aircraft located at the second end did not experience upward or downward movement.

[0090] If the average value is not zero, it is determined that the end of the transport aircraft located at the second end is experiencing an upward and downward movement.
