For example, if the device in the drawings is turned over, the element or feature described as "under" or "beneath" or "beneath" the other elements will be oriented as "above" the other elements or features. Thus, the exemplary terms "under" and "under" can include both upper and lower orientations.

[0028] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element or connected to the other element through an intervening element. In addition, the "connection" in the following embodiments should be understood as "electrical connection", "communication connection", etc., if there is transmission of electrical signals or data between the connected objects.

It should also be understood that the terms "include," "comprising," "having," and the like specify the presence of stated features, integers, steps, operations, components, parts, or combinations thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof. Furthermore, the term "and / or" as used in this specification includes any and all combinations of the relevant listed items.

[0030] As mentioned in the background technology, the feeding system of the dumper in the prior art is prone to the problem that materials accumulate on the feed grid and are difficult to be reliably detected, thereby posing the risk of machine damage accidents caused by excessive material accumulation in the hopper and collision of the dumper with the materials. The inventors have found that the reason for this problem is that the existing feeding system of the dumper generally detects the material level inside the hopper through a camera, which requires long-term monitoring by staff, is time-consuming and labor-intensive, and has low accuracy. In addition, the camera is easily affected by dust, smoke, etc., which may cause staff to make misjudgments.

[0031] Based on the above reasons, an embodiment of the present invention provides a method for detecting an ultra-high material level of a dumper feeding system. The dumper feeding system includes a belt conveyor, a dumper, a hopper, a radar material level detection module, and a pressure detection module. The hopper is used to receive the material dumped by the dumper and output the material to the belt conveyor. The radar material level detection module is used to detect the material level of the hopper and output a first material level signal. The pressure detection module is used to output a second material signal according to the amount of material on the feed grid of the hopper. It can be understood that in engineering practice, the various material level detection modules arranged in sequence from top to bottom of the hopper are often referred to as ultra-high material level, high material level, low material level, etc. Each material level detection module can detect a specific material level height, and the pressure detection module is a module for detecting the material above the feed grid. Please refer to Figure 1 The ultra-high material level detection method includes step S102 and step S104.

[0032] S102, obtaining a first material signal and a second material signal.

[0033] S104 , when the first material signal and the second material signal match, obtaining an ultra-high material level signal according to the first material signal and the second material signal.

[0034] It can be understood that the super-high material level signal is used to reflect the specific material level of the material in the hopper after it exceeds the super-high material level. It is currently more common to detect the material level through a radar material level detection module, but the working scene of the hopper may have a lot of coal dust, smoke, dust, etc., which will affect the detection accuracy of the radar material level detection module. Therefore, a pressure detection module is also provided in this embodiment, so that the detection results of the pressure detection module and the radar detection module can be cross-verified, and only when the first material signal and the second material signal match can it be determined that the detection results of the pressure detection module and the radar detection module are more accurate. The first material signal and the second material signal match can be that the difference between the two is less than a preset threshold. The super-high material level signal obtained according to the first material signal and the second material signal can be the average value of the first material signal and the second material signal, or the detection accuracy of the radar detection module and the pressure detection module can be obtained, and the material signal output by the module corresponding to the high detection accuracy is the super-high material level signal.

[0035] Based on the ultra-high material level detection method for the dumper feeding system of this embodiment, a radar detection module and a pressure detection module related to material level detection are provided in the dumper feeding system. The first material level signal and the second material level signal output by the radar detection module and the pressure detection module, respectively, can be cross-validated with each other. After the cross-validation is passed, an ultra-high material level signal that reliably reflects the ultra-high material level condition can be obtained based on the first material level signal and the second material level signal. This ultra-high material level detection method greatly improves the reliability of ultra-high material level detection, provides a basis for the safe control of the dumper feeding system, and ensures the safety of the dumper feeding system.

[0036] In one embodiment, the ultra-high material level detection method includes steps S202 to S206.

[0037] S202, obtaining a first material signal and a second material signal.

[0038] S204 , when the first material signal and the second material signal match, obtaining an ultra-high material level signal according to the first material signal and the second material signal.

[0039] The description of step S204 can refer to the description of step S104.

[0040] S206, when the super-high material level signal is greater than the first threshold, the dumper corresponding to the hopper is controlled to stop dumping, and the dumper corresponding to the hopper is controlled to continue dumping after the super-high material level signal is less than the first threshold.

[0041] It can be understood that the material unloaded by the dumper corresponding to the hopper will fall into the hopper. The super-high material level signal being greater than the first threshold value means that there is material accumulation on the feed grille of the hopper. The continuous unloading of the dumper may collide with the accumulated material. In order to ensure the safety of the dumper feeding system, the dumper corresponding to the hopper is controlled to stop unloading. After the dumper stops unloading, the hopper will continue to output the material inside the hopper to the belt conveyor, and the material level of the hopper will drop. After the super-high material level signal drops to less than the first threshold value, the dumper will be able to unload normally, and the dumper corresponding to the hopper will be controlled to continue unloading. From the perspective of system efficiency, steps S202 and S204 can be continuously executed to obtain a real-time super-high material level signal, and whether the dumper can be controlled to continue unloading can be determined based on the super-high material level signal. From the perspective of energy saving, steps S202 and S204 can also be executed at preset intervals. To prevent misjudgment caused by data fluctuations, the dumper corresponding to the hopper can be controlled to stop dumping when the duration of the ultra-high material level signal exceeding the first threshold exceeds the first time threshold. In a specific embodiment, the ultra-high material level signal can be a current signal of 4mA to 20mA, and the first threshold can be 6mA.

[0042] In one embodiment, there are multiple hoppers, each of which is provided with a feeding device, which is used to control the amount of material output from the hopper to the belt conveyor. The radar level detection module and the pressure detection module correspond to each hopper one by one. Figure 3 The ultra-high material level detection method includes steps S302 to S308.

[0043] S302, obtaining a first material signal and a second material signal.

[0044] S304 , when the first material signal and the second material signal match, obtaining an ultra-high material level signal according to the first material signal and the second material signal.

[0045] The description of step S304 can refer to the description of step S104. In the case where there are multiple hoppers, each hopper will have a corresponding super-high material level signal.

[0046] S306: Determine the target feeding device according to each super-high material level signal.

[0047] The target feeding device is the feeding device for the hopper whose over-high material level signal is greater than the second threshold. It can be understood that an over-high material level signal greater than the second threshold indicates excessive material accumulation in the hopper. This can be achieved by increasing the amount of material delivered to the belt conveyor to accelerate the reduction of the hopper's material level. Therefore, the target feeding device for which the material output needs to be increased is first determined based on each over-high material level signal.

[0048] S308, controlling the target feeding device to increase the material output and controlling the feeding devices other than the target feeding device to reduce the material output, so that the feeding amount of the belt conveyor remains unchanged.

[0049] It is understood that the feed rate of a belt conveyor refers to the amount of material delivered by the belt conveyor to its destination, such as a storage yard or coal yard. Because storage yards and coal yards require other equipment to transport or stack the material delivered by the belt conveyor, their processing capacity for the belt conveyor's feed is limited. After increasing the output rate of the target feeding device, to ensure that the storage yard or coal yard can promptly process the belt conveyor's feed, it is necessary to reduce the material output rate of feeding devices other than the target feeding device. Furthermore, steps S306 and S308 can also be used in conjunction with step S206, i.e., stopping the dumper and increasing the material output of the hopper, causing the material level in the hopper to drop rapidly. For safety reasons, stopping the dumper should be prioritized. Therefore, the first threshold value can be set to a value less than the second threshold value. In one specific embodiment, the over-high material level signal can be a current signal between 4 and 20 mA, with the first threshold value being 6 mA and the second threshold value being 10 mA.

[0050] In one embodiment, the feeding device is a vibrating feeder.

[0051] In one embodiment, when the first material signal and the second material signal do not match, an alarm prompt signal is output. Specifically, when the first material signal and the second material signal do not match, it means that there is a problem with the radar material level detection module or the pressure detection module, resulting in inaccurate detection results of the ultra-high material level. The alarm prompt signal is output to inform the staff to troubleshoot in time. The alarm prompt signal can be an acoustic signal or a light signal, etc. The dumper feeding system can also include a wireless communication device, which is used to connect to the terminal device of the staff. The alarm prompt signal can be wirelessly transmitted to the staff, making it convenient for the staff to troubleshoot in time.

[0052] It should be understood that although Figure 1-Figure 3 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. In addition, Figure 1-Figure 3 At least part of the steps may include multiple steps or multiple stages. These steps or stages are not necessarily performed at the same time, but can be performed at different times. The order of execution of these steps or stages is not necessarily one by one, but can be performed in turn or alternately with other steps or at least part of the steps or stages in other steps.

[0053] On the other hand, an embodiment of the present invention further provides a feeding system for a tipper 13, which includes a belt conveyor 11, a tipper 13, a hopper 15, a radar material level detection module 17, a pressure detection module 19, and a control module 21. The hopper 15 is used to receive the material unloaded by the tipper 13 and output the material to the belt conveyor 11. The radar material level detection module 17 is used to detect the material level of the hopper 15 and output a first material level signal. The pressure detection module 19 is used to output a second material signal based on the amount of material on the feed grid of the hopper 15. The control module 21 is connected to the radar material level detection module 17 and the pressure detection module 19, and includes a memory and a processor. The memory stores a computer program, and when the processor executes the computer program, it realizes: obtaining a first material signal and a second material signal; and obtaining an ultra-high material level signal based on the first material signal and the second material signal when the first material signal and the second material signal match.

[0054] Based on the feeding system of the dumper 13 in this embodiment, the feeding system of the dumper 13 is provided with a radar detection module and a pressure detection module 19 related to material level detection. The first material level signal and the second material level signal output by the radar detection module and the pressure detection module 19, respectively, can be cross-validated with each other.

This feeding system of the dumper 13 greatly improves the reliability of ultra-high material level detection and has high safety.

[0055] In one embodiment, when the processor executes the computer program, the steps of the ultra-high material level detection method in any of the above embodiments are implemented.

[0056] In one embodiment, see Figure 4 The pressure detection module 19 includes a base 19A and a flexible sensing surface 19B provided on the base 19A, and a pressure detection unit 19C. The base 19A is provided on the upper part of the feed grid 15A. The flexible sensing surface 19B is used to cushion the materials unloaded by the dumper 13. The flexible sensing surface 19B is made of a flexible material, and the impact force of the material will be alleviated by the flexible sensing surface 19B and will not directly hit the hopper 15. The pressure detection unit 19C is used to detect the amount of material on the flexible sensing surface 19B and output a second material signal. When the material level in the hopper 15 exceeds the super-high material level, material will accumulate on the flexible sensing surface 19B, and the pressure detection unit 19C can detect the amount of material accumulated on the flexible sensing surface 19B. The pressure detection unit 19C may include a pressure sensor, a piezoelectric sheet, and the like.

[0057] In one embodiment, see Figure 5 and Figure 6The pressure detection module 19 also includes a shielding protective member 19D, which is arranged on the base 19A to prevent the material unloaded by the tipping machine 13 from impacting the base 19A and to guide the material unloaded by the tipping machine 13 to the flexible sensing surface 19B. The shape of the shielding protective member 19D can be selected according to actual conditions and does not have to be Figure 6 The cone in the.

The signal acquisition module 110 is used to acquire a first material signal and a second material signal. The processing module 130 is used to obtain an ultra-high material level signal based on the first material signal and the second material signal when the first material signal and the second material signal match.
