Detailed Description

Embodiments of the present disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the present disclosure and are not to be construed as limiting the present disclosure. On the contrary, the embodiments of the disclosure include all alternatives, modifications, and equivalents as may be included within the spirit and scope of the appended claims.

As shown in fig. 1 and 2, the embodiment of the disclosure provides a material level detection system for a mine car 3, including at least one detection module 1 and a processing module 2, the detection module 1 includes an ultrasonic sensor 11, a first detection end of the ultrasonic sensor 11 faces an inner wall of the mine car 3, a second detection end of the ultrasonic sensor 11 faces a material port of the mine car 3, an input end of the processing module 2 is connected with an output end of the ultrasonic sensor 11, and the processing module 2 is used for detecting a communication loop of the ultrasonic sensor 11 according to a first signal of the first detection end of the ultrasonic sensor 11, and detecting an upper limit material level of a material according to a second signal of the second detection end of the ultrasonic sensor 11 when the communication loop of the ultrasonic sensor 11 is normal.

It can be understood that when a plurality of mine cars 3 pass through the ultrasonic sensor 11 in turn, because the first detection end of the ultrasonic sensor 11 faces the inner wall of the mine car 3, the ultrasonic sensor 11 can generate a first signal which changes regularly by utilizing the gaps between the inner walls of the mine cars 3 and the adjacent mine cars 3, so that the processing module 2 can detect the communication loop of the ultrasonic sensor 11 according to the first signal which changes regularly and judge whether the communication loop is normal, and further, when the communication loop of the ultrasonic sensor 11 is normal, the upper limit material level of the material is detected according to the second signal of the second detection end of the ultrasonic sensor 11, thereby meeting the material level detection requirement.

Meanwhile, as the processing module 2 can detect the communication loop of the ultrasonic sensor 11 according to the first signal, the material level detection system of the mine car 3 achieves a self-checking function, thereby effectively improving the reliability of the material level detection system of the mine car 3, enabling operators to discover faults in time and overhaul, avoiding the problems of overflow and the like caused by loading of mineral aggregate, ensuring high economical efficiency and high transportation efficiency of mineral aggregate transportation, and further meeting the use requirements.

It should be noted that the material level detection system of the mine car 3 may be applied to a transportation system of mineral aggregate, for example, the plurality of mine cars 3 travel along a travel route and stay at a predetermined position under the dragging of an electric locomotive, so that the material opening of the discharging device 4 is opposite to the material opening of the mine car 3, after that, the discharging device 4 is opened and the material is loaded into the mine car 3 until the material level detection system of the mine car 3 detects the upper limit material level of the material by using the cooperation of the processing module 2 and the ultrasonic sensor 11, and finally, after the discharging device 4 is closed, the mine car 3 continues to travel along the travel route.

The structures of the mine cars 3 are the same, and the gaps between the adjacent mine cars 3 are the same, so that when the mine cars 3 sequentially pass through the ultrasonic sensor 11, whether the communication loop of the ultrasonic sensor 11 is normal can be accurately determined by determining whether the first signal is in a preset regular change.

When the processing module 2 detects that the communication loop of the ultrasonic sensor 11 is abnormal according to the first signal, an alarm signal can be sent out so as to stop and overhaul the transportation system of the mineral aggregate.

The ultrasonic sensor 11 is used for detecting the upper limit material level of the materials in the mine car 3 by utilizing the emission and the reception of ultrasonic waves, and the specific type of the ultrasonic sensor 11 can be set according to actual needs, which is not limited. Wherein, because the first detection end of the ultrasonic sensor 11 faces the inner wall of the mine car 3, and the second detection end of the ultrasonic sensor 11 faces the material opening of the mine car 3, the first detection end and the second detection end of the ultrasonic sensor 11 have different measuring ranges, and the measuring range of the first detection end of the ultrasonic sensor 11 is larger than the measuring range of the second detection end of the ultrasonic sensor 11.

The ultrasonic sensor 11 can adapt to severe environments such as more dust and high humidity by adopting a material level detection mode of image recognition relative to the installation of the camera, and has stronger environment adaptation capability and lower investment cost relative to the material level detection mode of laser radar.

The number of the detection modules 1 may be set according to actual needs, which is not limited. The number of the detection modules 1 is the same as the number of the mine cars 3, and when the number of the detection modules 1 is multiple, the detection modules 1 are in one-to-one correspondence with the mine cars 3.

The specific type of the processing module 2 may be set according to actual needs, which is not limited.

As shown in fig. 2, in some embodiments, the ultrasonic sensor 11 is disposed on one side of the mine car 3, and a first detection end of the ultrasonic sensor 11 is directed in an oblique direction toward the side wall of the mine car 3 remote from the ultrasonic sensor 11, and a second detection end of the ultrasonic sensor 11 is directed in an oblique direction toward the throat of the mine car 3.

It can be appreciated that, because the first detection end of the ultrasonic sensor 11 is disposed along the inclined direction, when the plurality of mine cars 3 pass through the ultrasonic sensor 11, the first detection end of the ultrasonic sensor 11 can more easily detect the gap between the adjacent mine cars 3, so that the first signal is changed regularly, and the stable self-detection of the material level detection system of the mine cars 3 is further ensured.

Because the second detection ends of the ultrasonic sensors 11 are all arranged along the inclined direction, when materials are loaded from the material inlet of the mine car 3 to the interior of the mine car 3, the second detection ends of the ultrasonic sensors 11 are not easy to be influenced by the loaded materials, and therefore higher detection precision of the material level detection system of the mine car 3 is ensured.

It should be noted that, since the first detection end of the ultrasonic sensor 11 is far away from the side wall of the ultrasonic sensor 11 toward the mine car 3 along the inclined direction, the range of the first detection end of the ultrasonic sensor 11 is the side wall of the ultrasonic sensor 11 far away from the mine car 3 from the ultrasonic sensor 11, and since the second detection end of the ultrasonic sensor 11 is directed toward the material port of the mine car 3 along the inclined direction, the range of the second detection end of the ultrasonic sensor 11 is the material port from the ultrasonic sensor 11 to the mine car 3.

The inclination angle of the inclination direction may be set according to actual needs, and is not limited thereto, and the inclination angle may be 10 degrees, 15 degrees, 20 degrees, 30 degrees, or the like, for example.

As shown in fig. 2, in some embodiments, the ultrasonic sensor 11 is disposed on a side of the mine car 3 proximate the discharging apparatus 4, and the ultrasonic sensor 11 is located below the discharging apparatus 4.

It can be appreciated that, because the ultrasonic sensor 11 is arranged on one side of the mine car 3 close to the discharging equipment 4, and the ultrasonic sensor 11 is positioned below the discharging equipment 4, the ultrasonic sensor 11 not only can stably detect the upper limit material level of the material of the mine car 3, but also can reduce the collision of the discharging equipment 4 to the ultrasonic sensor 11, thereby effectively prolonging the service life of the ultrasonic sensor 11 and ensuring the stable operation of the material level detection system of the mine car 3.

It should be noted that, the discharging device 4 is used for discharging the material into the mine car 3 to realize loading of the material, the specific type of the discharging device 4 may be set according to actual needs, which is not limited, and the discharging device 4 may be a vibratory feeder by way of example.

Thereby, the ultrasonic sensor 11 is positioned on one side of the mine car 3 close to the discharging device 4, and the ultrasonic sensor 11 is positioned above the mine car 3 and below the discharging device 4 while being inclined toward the material opening of the mine car 3.

As shown in fig. 1, in some embodiments, the detection module 1 further includes a calibration support 12, the calibration support 12 is disposed at a front end of the mine car 3, the height of the calibration support 12 is the same as the height of the upper limit level, and the processing module 2 is further configured to calibrate the ultrasonic sensor 11 according to the second signal when the calibration support 12 passes through the second detection end of the ultrasonic sensor 11.

It can be appreciated that, because the height of the check bracket 12 is the same as the height of the upper limit material level, when the check bracket 12 passes through the second detection end of the ultrasonic sensor 11, the ultrasonic sensor 11 can generate a second signal by using the check bracket 12, so that the processing module 2 can check the ultrasonic sensor 11 by using the second signal, thereby effectively improving the reliability of the mine car 3 material level detection system, enabling operators to discover faults in time and overhaul, avoiding the problem of excessive loading or more of mineral aggregates, ensuring the accurate transportation of the mineral aggregates, and meeting the use requirements.

When the calibration stand 12 passes the second detection end of the ultrasonic sensor 11, if the ultrasonic sensor 11 generates the second signal, it indicates that the position, the parameter, etc. of the ultrasonic sensor 11 are not shifted.

When the checking bracket 12 passes through the second detection end of the ultrasonic sensor 11, if the ultrasonic sensor 11 does not generate the second signal, it indicates that the position, the parameter, etc. of the ultrasonic sensor 11 are shifted, and at this time, the mine car 3 level detection system sends out an alarm signal, so that the operator can overhaul and adjust the ultrasonic sensor 11 in time.

The specific type of the calibration support 12 may be set according to actual needs, and this is not limiting, and the calibration support 12 may be set on an electric locomotive located at the front end of the mine car 3, and the calibration support 12 may be a calibration plate in a horizontal direction.

As shown in fig. 1, in some embodiments, the processing module 2 includes a data acquisition unit 21 and a data processing unit 22, where an input end of the data acquisition unit 21 is connected to an output end of the ultrasonic sensor 11, an input end of the data processing unit 22 is connected to an output end of the data acquisition unit 21, an output end of the data processing unit 22 is connected to an input end of the control system 5 of the mine car 3, and the data processing unit 22 is configured to receive the first signal and the second signal acquired by the data acquisition unit 21, and output an upper limit level signal of the material to the control system 5.

It will be appreciated that, since the input end of the data acquisition unit 21 is connected to the output end of the ultrasonic sensor 11, the input end of the data processing unit 22 is connected to the output end of the data acquisition unit 21, so that the first signal detected by the first detection end of the ultrasonic sensor 11 can be output to the data processing unit 22 through the data acquisition unit 21, and the data processing unit 22 can perform self-detection according to the first signal, and at the same time, the second signal detected by the second detection end of the ultrasonic sensor 11 can be output to the data processing unit 22 through the data acquisition unit 21, and the data processing unit 22 can detect the upper limit level of the material according to the second signal, thereby meeting the use requirement.

Moreover, as the output end of the data processing unit 22 is connected with the input end of the control system 5 of the mine car 3, the upper limit material level signal of the mine car 3 obtained by the data processing unit 22 can be output to the control system 5 of the mine car 3, so that the control system 5 of the mine car 3 can conveniently realize automatic operation according to the upper limit material level signal of the mine car 3, and further, the high-efficiency transportation requirement of mineral aggregate is met.

It should be noted that, the data acquisition unit 21 is configured to acquire the first signal and the second signal of the ultrasonic sensor 11, and the specific type of the data acquisition unit 21 may be set according to actual needs, which is not limited.

The specific type of the data processing unit 22 may be set according to actual needs, which is not limited thereto, and the data processing unit 22 may be a controller, a single chip microcomputer, a micro control unit, or the like, for example.

The control system 5 of the mine car 3 is used for automatic control of the mine car 3, and the control system 5 can control running of the mine car 3, switching of the discharging equipment 4 and the like, wherein when the data processing unit 22 judges that the ultrasonic sensor 11 is abnormal according to the first signal and/or the second signal, an alarm signal can be output to the control system 5, so that the control system 5 can control facilities such as the mine car 3 to stop running.

As shown in fig. 1, in some embodiments, the processing module 2 further includes a delay unit 23, where the delay unit 23 is disposed between the output end of the data processing unit 22 and the input end of the control system 5, the input end of the delay unit 23 is connected to the output end of the data processing unit 22, the output end of the delay unit 23 is connected to the input end of the control system 5, and the delay unit 23 is configured to delay the upper limit level signal output by the data processing unit 22 to the control system 5;

It can be understood that by setting the delay unit 23, the upper limit level signal output by the data processing unit 22 can be delayed to reach the control system 5, so that after the level of the mine car 3 reaches the upper limit, the loading of the material can be stopped after the set time is continued, and therefore, the loading of the material can adapt to the uneven structure of the material surface, and the loading capacity of the mine car 3 is effectively improved.

It should be noted that, since the material is fixed at a certain position of the mouth of the mine car 3 for discharging, when the ultrasonic sensor 11 detects the second signal and makes the data processing unit 22 obtain the upper limit level of the mine car 3, the mineral aggregate at the position is more, and the mineral aggregate at other positions is less, so that the material level of the material forms a conical stacking structure, and at this time, the average level of the material does not reach the set upper limit level.

Through making the material stop loading again after the material level of mine car 3 reaches the upper limit after the setting time that lasts, can effectively increase the average material level height of material to guarantee the great loading capacity of mine car 3, simultaneously, in mine car 3 transportation, the material that is the toper and piles up the structure can tend to level gradually under the vibration of mine car 3, avoids the material too high to influence the traveling of mine car 3 and causes the flash problem.

The specific type of the delay unit 23 may be set according to actual needs, and the delay unit 23 may be a delay circuit formed of a time relay or the like as an example.

The setting time can be set according to actual needs, and is not limited.

As shown in fig. 1, in some embodiments, the processing module 2 further includes a filtering unit 24, where the filtering unit 24 is disposed between the input end of the data processing unit 22 and the output end of the data collecting unit 21, the input end of the filtering unit 24 is connected to the output end of the data collecting unit 21, the output end of the filtering unit 24 is connected to the input end of the data processing unit 22, and the filtering unit 24 is configured to filter the interference signal output by the data collecting unit 21 to the data processing unit 22.

It can be appreciated that, because the ultrasonic sensor 11 has higher sensitivity, and the material is easy to splash when loaded in the mine car 3, so that the interference signals in the material level detection system of the mine car 3 are more, the interference signals output from the data acquisition unit 21 to the data processing unit 22 can be effectively filtered through the arrangement of the filtering unit 24, thereby ensuring that the material level detection system of the mine car 3 accurately detects the upper limit material level of the mine car 3.

It should be noted that the interference signal may be a second signal detected by the second detection end of the ultrasonic sensor 11, and the duration of the second signal is less than a set time threshold, where the time threshold may be set according to actual needs, which is not limited.

The specific type of the filter unit 24 may be set according to actual needs, which is not limited, and the filter unit 24 may be a filter circuit formed of a capacitor or the like.

Meanwhile, since the first fixing holes 141 are formed in a plurality along the rotation direction of the second bracket 14, and the first threaded holes 131 are formed in a plurality along the rotation direction of the second bracket 14, when the threaded rods of the first positioning bolts 15 penetrate through the first fixing holes 141 at different positions and the first threaded holes 131 at different positions, different first preset angles between the first bracket 13 and the second bracket 14 can be realized, and therefore, the angle adjustment of the ultrasonic sensor 11 can be realized through the position matching among the first positioning bolts 15, the first fixing holes 141 and the first threaded holes 131, so that different use requirements are met, and the flexibility and the universality of the mine car 3 material level detection system are higher.
