Description

Technical Field

[0001] The present disclosure relates to the technical field of material detection, and in particular to an intelligent silo management system with inventory inspection and warehouse clearance guidance functions. Background Art

[0002] At present, there is a need to frequently clean silos and conduct inventory counting for storing materials. In the existing solutions, either the material data information is obtained through radar level meters to count the materials, or the silo cleaning process is performed through a silo cleaning robot. Both are independent detection processes.

[0003] When materials are in storage state, during feeding, after feeding, during discharging or after discharging, the radar level meter can be used to obtain material surface data information in real time, and then obtain material data information in the silo to realize the material inventory counting function. It only detects the material data and displays it interactively through the display device. For the material discharging or clearing process, the existing scheme usually adopts a clearing robot to perform the clearing operation, which mainly uses the camera to obtain the material remaining amount and the position of the clearing robot, and then guides the clearing robot to perform path planning according to the material data to guide the clearing.

[0004] For example, see patent CN116673958A, which discloses a grain silo cleaning robot based on artificial intelligence, in which a radar module is used to establish a grain silo map, a path planning module provides accurate navigation capabilities, a host module is used to control the movement of the silo cleaning robot, and a mechanical arm and a suction device cooperate to complete the silo cleaning and grain release. The silo cleaning robot is set on the outer surface of the silo, and absorbs materials through the suction port and allows the grain to enter the storage cavity at the rear of the silo cleaning robot through the auxiliary grain channel, thereby achieving the completion of the silo cleaning task without manpower costs, liberating manpower and saving costs. In this patent, the silo cleaning robot is next to the material, and the material cleaning process can be achieved by scanning the material and the path planning module.

[0005] However, in the case where there is both feeding and discharging of materials during the storage process in the silo, a clearing device is provided at the bottom of the material. Further improvement is needed in terms of how to intelligently measure material data and when and how to perform intelligent clearing in order to realize automatic inventory and intelligent clearing.

[0006] For this reason, the art needs a silo intelligent management system that can take inventory and guide warehouse clearance. Summary of the invention

[0043] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0044] It should be noted that all actions of obtaining signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where they are located and with the authorization given by the owner of the corresponding device.

[0045] like Figure 1 As shown, the silo intelligent management system with the functions of inventory inspection and warehouse cleaning guidance of the present invention comprises at least one scanning device 20, at least one warehouse cleaning auger 10 and a control device 30. Among them, at least one of the scanning devices 20 is arranged on the top of the silo, and is at least used to scan the material surface of the material 50 in the silo 40 to obtain material characteristic information; the warehouse cleaning auger 10 is arranged at the bottom of the silo 40, and is used to discharge and clean the material 50 in the silo 40, and send position information to the control device 30; the control device 30 is used to receive and switch the daily inventory inspection working mode or the warehouse cleaning guidance working mode according to the material characteristic information and the position information of the warehouse cleaning auger 10, so as to realize data interaction with the scanning device 20 and the warehouse cleaning auger 10.

[0046] At least one of the scanning devices 20 provided in the present invention sends out a detection signal at least within a preset angle range, performs multi-point scanning on the surface of the material 50 in the silo 40, obtains the ranging information corresponding to each point in the preset angle range, calculates the material characteristic information, and transmits it to the control device 30; or, at least one of the scanning devices 20 obtains the ranging information corresponding to each point in the preset angle range and transmits it to the control device 30, and the control device 30 calculates the material characteristic information.

[0047] It should be noted that the cleaning auger 10 is arranged at the bottom of the silo 40. When the material level is high, the cleaning auger 10 is completely at the bottom of the material in the silo 40, or partially inside the material in the silo 40. When the material level is low, the cleaning auger 10 is completely exposed to the surface of the material in the silo 40, or partially exposed to the surface of the material. When the material level is high, it may be a material storage process or a feeding process. At this time, the cleaning auger 10 may not work, and the material characteristic information of the material surface can be obtained only through the scanning device 20 to realize daily inspection operations; when the material level is low, it may be a material discharging process. At this time, it is necessary to combine the material characteristic information obtained by the scanning device 20 and the position information of the cleaning auger 10 to analyze and determine which area has more materials and which area has less materials, and then guide the cleaning auger 10 to move to the area with more materials to perform the cleaning operation, until the material level value at the bottom of the silo is lower than the set material level threshold value to complete the cleaning operation, and then the cleaning auger 10 stops working.

[0048] Since the cleaning auger 10 has a certain volume, the control device 30 needs to perform three-dimensional modeling based on the three-dimensional parameter information of the cleaning auger 10, wherein the three-dimensional parameter information of the cleaning auger 10 can obtain its accurate size information through the design drawings. In order to intuitively display the material characteristic information in the silo 40, the position information of the cleaning auger 10 set at the bottom of the silo 40 or the bottom of the material in the silo 40, and the three-dimensional model of the cleaning auger 10, the material characteristic information in the silo 40, the position information of the cleaning auger 10 set at the bottom of the material, and the three-dimensional model of the cleaning auger 10 can be three-dimensionally displayed in the same display interface of the control device 30, thereby facilitating the silo manager to intuitively understand the material data information in the silo and the three-dimensional information of the cleaning auger in the silo. Alternatively, only the material characteristic information in the silo 40 and the position information of the cleaning auger 10 set at the bottom of the material can be directly displayed in the display interface.

[0049] The control device 30 of the present invention is capable of receiving the material characteristic information and the position information and three-dimensional model of the cleaning auger 10 acquired by the scanning device 20, and displaying the acquired material characteristic information and position information on the same display interface, and performing inventory operations and guiding the cleaning auger 10 to guide the cleaning work in combination with the material characteristic information. In this way, the automated management of materials 50 and cleaning can be realized, and the automatic inventory of the silo 40 and automated cleaning guidance can be realized without human intervention in an unattended manner, thereby deeply tapping the potential of silo management, making the management of the silo 40 intelligent and information-based, data visualization and process transparency, and unmanned and automated on-site operations, which significantly enhances safety prevention capabilities, improves efficiency, and reduces costs.

[0050] In a further embodiment of the present invention, when the material level value (at least one of the average material level value, the minimum material level value, or the maximum material level value) in the material characteristic information is less than or equal to the preset material level threshold, the control device 30 switches to the warehouse clearance guidance working mode. Conversely, when the material level value (at least one of the average material level value, the minimum material level value, or the maximum material level value) in the material characteristic information is greater than the preset material level threshold, the control device 30 switches to the daily inventory inspection working mode. Of course, the control device 30 switches to the daily inventory inspection working mode or the warehouse clearance guidance working mode when other conditions are met, and is not limited to judging the switching of the working mode by the material level value.

[0051] In a further embodiment of the present invention, the scanning device 20 includes at least one of a 3D laser scanning radar, a camera scanner or a 3D microwave scanning radar.

[0052] Among them, when at least one of the scanning devices 20 is a 3D laser scanning radar or a camera scanner, when guiding the clearing work mode, the clearing auger 10 performs a clearing operation at least based on the material feature information detected and obtained by the 3D laser scanning radar or the camera scanner.

[0053] Furthermore, when at least one of the scanning devices 20 used in the present invention is a 3D microwave scanning radar, in the guidance clearance working mode, the 3D microwave scanning radar switches the working logic to the regional scanning logic according to the real-time position of the clearance auger 10, and the 3D microwave scanning radar follows the clearance auger 10, at least scans and detects the material feature information within the area where the real-time position of the clearance auger 10 is located, and performs credibility control on the material feature information detected and obtained by the 3D laser scanning radar or the camera scanner. In the daily inspection working mode, the 3D microwave scanning radar uses normal scanning logic to scan the material surface in the silo in the entire area to obtain material feature information.

[0054] It should be understood that the 3D microwave scanning radar will switch the working logic to the regional scanning logic when guiding the warehouse cleaning working mode to at least scan and detect the area where the real-time position of the warehouse cleaning auger 10 is located, and the material characteristic information obtained can be used to control the credibility of the material characteristic information obtained by the 3D laser scanning radar or the camera scanner. In the daily inspection working mode, the normal scanning logic will be used to scan the material surface in the silo 40 in the entire area to obtain the material characteristic information.

[0055] When the control device 30 switches to the clearing guidance working mode, the control device 30 plans the clearing logic and route of the clearing auger 10 according to the position information and material characteristic information of the clearing auger, and the clearing auger 10 performs clearing operations according to the clearing logic and route; or, the clearing auger 10 itself plans the clearing logic and route according to the real-time material characteristic information to perform clearing operations, and sends the clearing logic and route, and the position information of the clearing auger to the control device 30 in real time to realize data interaction.

[0056] In the present invention, the clearing auger 10 can also plan the clearing logic and route according to the material characteristic information to perform the clearing operation, or the control device 30 can plan the clearing logic and route according to the material characteristic information to guide the clearing auger 10 to perform the clearing operation, thereby realizing data interaction between the clearing auger 10 and the control device 30.

[0057] In a further embodiment of the present invention, when the control device 30 switches to the clearing guidance working mode, the clearing auger 10 can also perform clearing operations according to its own preset clearing logic and route, and the clearing auger 10 interacts with the control device 30 in real time, and transmits at least one of the position information, power supply, current, rotation direction, and operating parameters of the clearing auger 10 to the control device 30 in real time and displays the interface.

[0058] Alternatively, the clearing auger 10 can also perform clearing operations according to its own preset clearing logic and route, and transmit its own real-time data information (for example: position information, power supply, current, rotation direction, operating parameters, etc.) to the control device 30 for interface display, thereby realizing data interaction with the control device 30.

[0059] In a further embodiment of the present invention, when the control device 30 switches to the warehouse clearing working mode, the warehouse clearing auger 10 performs the warehouse clearing operation according to the control instruction of the control device 30. That is, the control device 30 exchanges data with the warehouse clearing auger 10 and sends a control instruction to the warehouse clearing auger 10 to perform the warehouse clearing operation.

[0060] Specifically, the control instructions of the control device 30 may include the forward movement of the warehouse cleaning machine, the reverse movement of the warehouse cleaning machine, the main spiral operation, and the auxiliary spiral operation. The warehouse cleaning auger 10 interacts with the control device 30 in real time data. By clicking the forward button of the warehouse cleaning machine, the reverse button of the warehouse cleaning machine, the main spiral operation button, and the auxiliary spiral operation button set on the interface of the control device 30, the warehouse cleaning auger 10 performs the warehouse cleaning operation according to the corresponding control instructions.

[0061] The present invention directly sets buttons such as the forward button of the warehouse cleaning machine, the reverse button of the warehouse cleaning machine, the main spiral operation button, the auxiliary spiral operation button, etc. on the interface of the control device 30, so that the staff can guide the warehouse cleaning auger 10 to perform the clearing work of specific control instructions by operating the corresponding buttons, and also realizes the effect of intelligent management of the warehouse cleaning process and greatly saves labor costs.

[0062] In the daily inventory inspection working mode, the control device 30 controls the scanning device 20 to scan the material surface in the silo to obtain material feature information, thereby realizing the daily inventory inspection operation.

[0063] In a possible implementation of this embodiment, the silo intelligent management system with inventory inspection and warehouse clearance guidance functions may also include a feeding device. The control device 30 interacts with the feeding device for data, and after receiving the feeding instruction from the feeding device, switches to the daily inventory inspection working mode.

[0064] During the feeding process of the feeding device, a daily inspection working mode can be selected to perform real-time material scanning on the materials in the silo 40 for daily inspection, so as to obtain material characteristic information of the materials in the silo 40.

[0065] The material characteristic information includes at least one of a material level value, a three-dimensional shape of the material 50 in the silo 40, point cloud data, mass, volume, and volume percentage.

[0066] It should be noted that the control device 30 switches to the clearing guidance working mode and guides the clearing auger 10 to perform the clearing operation when at least one of the material level value, the mass, the volume, and the volume percentage is less than or equal to a preset threshold value; and / or the control device 30 switches to the clearing guidance working mode and guides the clearing auger 10 to perform the clearing operation when at least one of the material level value, the three-dimensional shape, the mass, the volume, and the volume percentage of the current detection cycle and the material level value, the three-dimensional shape, the mass, the volume, and the volume percentage of the previous detection cycle has a corresponding growth value less than a preset tolerance value.

[0067] Furthermore, the control device 30 switches to the daily inspection working mode when at least at least one of the material level value, the mass, the volume, and the volume percentage is greater than a preset threshold value; and / or the control device 30 switches to the daily inspection working mode when at least one of the material level value, the three-dimensional shape, the mass, the volume, and the volume percentage of the current detection cycle and the material level value, the three-dimensional shape, the mass, the volume, and the volume percentage of the material 50 in the silo 40 of the previous detection cycle has a growth value that exceeds a preset tolerance value.

[0068] The preset threshold and preset tolerance value when the control device 30 switches to the guidance clearing working mode can be set according to the form of the material 50 (large solid particles, powdered solids, etc.), different materials 50 (wheat, sand, corn, etc.) or silos 40 of different capacities (100L silo 40, 200L silo 40 or silos 40 of other capacities, etc.) Different preset thresholds or tolerance values ​​are set, and the preset threshold or tolerance value is not unique or fixed, and can be set according to specific circumstances. For example, if wheat is selected as the material, the preset threshold is set to 20% of the volume of wheat in the silo, that is, the preset threshold is 20%V 筒仓 , wheat in the silo is less than or equal to 20%V 筒仓 When the control device 30 switches to the warehouse clearing guidance working mode.

[0069] Similarly, when the control device 30 switches to the daily inspection working mode, the preset threshold or tolerance value will also be set according to the material 50 form (large solid particles, powdered solids, etc.), different materials 50 (wheat, sand, corn, etc.) or silos 40 of different capacities (100L silo 40, 200L silo 40 or silos 40 of other capacities, etc.). The preset threshold or tolerance value is not unique or fixed and can be set according to specific circumstances. For example, if wheat is selected as the material, the preset threshold is set to 20% of the volume of wheat in the silo, that is, the preset threshold is 20%V 筒仓 , wheat in silo greater than 20% V 筒仓 When the control device 30 is switched to the daily inspection working mode.

[0070] The tolerance value is the value within which the material characteristic information of the current test cycle and the previous test cycle is allowed to vary within a certain range. For example, taking the quality in the material characteristic information as an example, the tolerance value is set to 5% M 筒仓 , M 筒仓 is the mass value of the original material in the silo. If the mass difference between the current detection cycle and the previous detection cycle is less than or equal to 5% M 筒仓, indicating that the quality of the material in the silo has decreased in the current detection cycle compared with the previous detection cycle. At this time, the control device 30 needs to switch to the guidance clearance working mode; if the quality difference between the current detection cycle and the previous detection cycle is greater than 5% M 筒仓 , indicating that the quality of the material in the silo has increased in the current detection cycle compared with the previous detection cycle, for example, feeding has occurred. At this time, the control device 30 needs to switch to the daily inspection working mode.

[0071] Alternatively, a preset threshold or tolerance setting button can be set on the interface of the control device 30, and the staff can set it before clearing or counting the inventory based on work experience, or set different thresholds or tolerance values ​​for different operating systems, and the staff can directly select them on the interface of the control device 30; or for specific users, the control device 30 can set the preset threshold or tolerance value for clearing or counting the inventory in advance, and the staff only needs to monitor the interface display information of the control device 30 to fully understand the real-time material characteristic information of the material 50 in the silo 40.

[0072] The warehouse cleaning auger 10 and the control device 30 in the present invention can realize data interaction. In order to be able to understand the position information of the warehouse cleaning auger 10 in real time to control the operation of the warehouse cleaning auger 10, the control device 30 needs to obtain the position information of the warehouse cleaning auger 10 in a timely manner. It should be noted that the position information of the warehouse cleaning auger 10 is obtained by detecting the self-contained position detection module 15 or the position detection module 15 set on the warehouse cleaning auger 10 and transmitted to the control device 30.

[0073] In a further embodiment of the present invention, when a position detection module 15 is provided on the warehouse cleaning auger 10 to detect and obtain the position information of the warehouse cleaning auger 10, the position detection module 15 includes at least one of a capacitive proximity switch, an inductive proximity switch, and a magnetic proximity switch.

[0074] like Figure 2 As shown, the silo cleaning auger 10 of the present invention is at least provided with a transmission device 11, a fixed support structure 12 and a conveying device 13. The transmission device 11 and the conveying device 13 are fixedly connected through the fixed support structure 12. The conveying device 13 is controlled by the transmission device 11 to move and is used to convey the material 50 in the silo 40 for discharging and silo cleaning operations. Figure 3As shown, the transmission device 11 at least includes a horizontal rotating part, N metal modules 14 are arranged on an outer circle of the horizontal rotating part, and at least one of the capacitive proximity switch and the inductive proximity switch is arranged below the metal module 14. When the clearing auger 10 rotates horizontally, the N metal modules 14 arranged on the horizontal rotating part perform synchronous mechanical movement, and the capacitive proximity switch and the inductive proximity switch generate a corresponding position signal and transmit it to the control device 30 when each metal module 14 moves above it, wherein the capacitive proximity switch and the inductive proximity switch are fixedly arranged on the fixed support structure 12.

[0075] It should be noted that the N metal modules 14 are arranged at equal intervals or at unequal intervals.

[0076] In order to facilitate the rapid acquisition of the position information of the cleaning auger 10, the zero point direction of the scanning device 20 and the 0 angle of the metal module 14 can be unified to the same direction, and the control device 30 places the scanning device 20 and the cleaning auger 10 in a unified coordinate system to obtain the three-dimensional shape detected by the scanning device 20, the point cloud data and the position information of the cleaning auger 10.

[0077] Preferably, the position of one of the metal modules on the horizontal rotating part is selected as 0 angle, so as to determine the angle information corresponding to N metal modules, and a magnet is correspondingly arranged at the 0 angle position of the horizontal rotating part or at a fixed angle position spaced apart from the 0 angle position (i.e., at other angle positions that are a certain angle away from or spaced apart from the 0 angle position), and a magnetic proximity switch is arranged below or horizontally opposite the magnet, so as to calibrate and verify the position information of the warehouse clearing auger 10, wherein the magnetic proximity switch is fixedly mounted on the fixed support structure 12.

[0078] The present invention can realize the automated management of material inventory and clearance, and can realize the automatic inventory of silo 40 and automatically guide clearance without human intervention in an unattended situation, thereby deeply tapping the potential of silo management, making the management of silo 40 intelligent and information-based, data visualization and process transparency, and unmanned and automated on-site operations, thereby significantly improving safety prevention capabilities, increasing efficiency, and reducing costs.

[0079] The control device in the present invention switches the daily inventory inspection working mode or the clearing guidance working mode through the material characteristic information in the silo, the three-dimensional model of the clearing auger 10 and the position information of the clearing auger 10. In particular, for the situation where the clearing auger 10 is at the bottom of the material in the silo, the clearing logic and route of the clearing auger 10 can be intelligently controlled to realize intelligent clearing in the silo 40. At the same time, in the daily inventory inspection working mode, the scanning device 20 is controlled to perform multi-point scanning on the material surface of the material 50 to obtain material characteristic information to realize the intelligent inventory inventory inspection function.
