[0032] 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.

[0033] It should be noted that all actions of acquiring 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 the device is located and with the authorization given by the owner of the corresponding device.

[0034] Stacker-reclaimer is mainly a highly efficient equipment for continuous loading and unloading of bulk materials in modern industry. It is widely used in stacking and reclaiming operations in bulk material storage yards such as ports, docks, metallurgy, cement, steel mills, coking plants, coal storage plants, power plants, etc.

[0035] In the related art, before the stacker-reclaimer operates, the stacker-reclaimer is pre-configured with related steps such as timed tasks, so that the stacker-reclaimer enters the operating state through the configured related steps. However, the inventors have found that when the stacker-reclaimer is controlled to operate by the method in the related art, during the stacking and reclaiming operation, when the stacker-reclaimer has an abnormal situation, the abnormal situation cannot be monitored, and thus the operating parameters of the stacker-reclaimer cannot be adjusted, which may reduce the stability of the stacker-reclaimer operation.

[0036] In view of this, the present disclosure provides an operation and maintenance method and corresponding device of a stacker-reclaimer to solve the technical problems existing in the related art.

[0037] like Figure 1 As shown, Figure 1 is a schematic diagram showing an operation and maintenance method of a stacker-reclaimer according to an exemplary embodiment of the present disclosure, with reference to Figure 1 ,include: S101: Determine monitoring information of a belt conveyor in a stacker-reclaimer in operation; S102: Generate target warning information according to the monitoring information; S103: Determine the target abnormal operation parameter corresponding to the stacker-reclaimer when generating the target warning information; S104: determining a target fault cause of the belt conveyor according to the target abnormal operation parameter and a preset fault association relationship, wherein the preset fault association relationship is a corresponding relationship between the abnormal operation parameter and the fault cause; S105: Display the monitoring information, the target warning information and the target failure cause.

[0038] Through the above technical scheme, target warning information is generated through the monitoring information of the belt conveyor in the stacker and reclaimer under the running state; and after the stacker and reclaimer generates the target warning information, the target abnormal operation parameters corresponding to the stacker and reclaimer are determined, and then the target fault cause of the belt conveyor is determined according to the target abnormal operation parameters and the preset fault association relationship, and the monitoring information, target warning information and target fault cause are displayed. Among them, the preset fault association relationship is the corresponding relationship between the abnormal operation parameters and the fault cause. After the stacker and reclaimer generates the target warning information, the target abnormal operation parameters of the stacker and reclaimer are obtained, and the target fault cause is determined according to the target abnormal operation parameters, and then the monitoring information, target warning information and target fault cause are displayed, so that relevant personnel can adjust the operating parameters of the stacker and reclaimer, which can improve the stability and accuracy of the stacker and reclaimer operation, and at the same time, the intelligent control of the stacker and reclaimer can be realized.

[0039] In order to enable those skilled in the art to better understand the operation and maintenance method of the stacker-reclaimer provided by the present disclosure, the above steps are described in detail with examples below.

[0040] For example, a belt conveyor can be used to continuously stack or reclaim materials in a certain manner. In this embodiment, monitoring information of the belt conveyor in the stacker and reclaimer can be monitored in real time, and whether the belt conveyor has abnormal operation can be monitored in real time based on the monitoring information.

[0041] The monitoring information may be at least one of the first image information of the belt and rollers in the belt conveyor, the second image information of the belt conveyor at the material drop port, the friction sound signal between the belt and rollers during the operation of the belt conveyor, and the coal flow temperature on the belt in the belt conveyor.

[0042] The first image information and the second image information can be collected by an image acquisition module, wherein the image acquisition module can be a camera, and the embodiments of the present disclosure do not make specific limitations on this. The friction sound signal can be collected by a signal acquisition module, wherein the signal acquisition module can be a sound sensor or an audio signal collector, and the embodiments of the present disclosure do not make specific limitations on this. The coal flow temperature can be detected by a temperature detection module, wherein the temperature detection module can be a temperature sensor, and the embodiments of the present disclosure do not make specific limitations on this.

[0043] In a possible manner, the coal flow temperature is measured by a temperature detection module arranged on the stacker and reclaimer, wherein the temperature detection module is arranged in at least one structure of the drive roller bearing seat, stacking belt reducer, slewing reducer, walking mechanism wheel group reducer, pitch wire rope reducer, reclaiming scraper drive wheel bearing seat, and scraper reducer in the stacker and reclaimer.

[0044] It should be understood that the temperature of the coal flow can be detected by the temperature detection module. In addition, multiple temperature detection modules can be set in the stacker-reclaimer, and the temperature detection module can be set in the drive roller bearing seat, stacking belt reducer, rotary reducer, walking mechanism wheel group reducer, pitch wire rope reducer, reclaimer scraper drive wheel bearing seat, scraper reducer and other structures in the reclaimer, and the embodiments of the present disclosure do not make specific limitations on this.

[0045] For example, target warning information of the stacker-reclaimer may be generated based on the monitoring information.

[0046] In a possible manner, generating target warning information according to the monitoring information includes: The first image information of the belt and the roller in the belt conveyor of the monitoring information is processed by a position comparison algorithm to obtain the position information of the belt, and when the position information is not in the preset position information, a first warning information is generated, and the first warning information is determined as the target warning information, wherein the preset position information is the running track information of the belt and the roller when the belt conveyor is in normal operating state.

[0047] It should be understood that if Figure 2 As shown, when the detection information is the first image information, it can be determined by the first image information whether the belt in the belt conveyor has deviated. The first image information can be processed by a position comparison algorithm to obtain the position information of the belt. The position information is compared with the preset position information. When the position information is not in the preset position information, a first warning information can be generated. The preset position information can be the running track information of the belt and the roller when the belt conveyor is in normal operation, that is, the position information of the belt in the belt conveyor without deviation. When the position information is not in the preset position information, it can represent that the belt is not on the running track of the belt and the roller, and the belt has deviated. The first warning information generated can be the warning information of the belt deviation.

[0048] In a possible manner, the position matching algorithm is any one of an edge detection algorithm, a contour detection algorithm, a shape matching algorithm and a support vector machine method.

[0049] It should be understood that the position comparison algorithm can be used to detect the position information of the belt in the first image information. The first image information can be processed by any one of the edge detection algorithm, contour detection algorithm, shape matching algorithm and support vector machine method to obtain the position information of the belt. Among them, the edge detection algorithm, contour detection algorithm, shape matching algorithm and support vector machine method are all methods for detecting image position information in the related art, and will not be repeated here.

[0050] In a possible manner, generating target warning information according to the monitoring information includes: The second image information of the belt conveyor at the material drop port in the monitoring information is detected by a foreign matter judgment method. When a foreign matter is detected in a preset area of ​​the second image information, a second warning information is generated, and the second warning information is determined as the target warning information, wherein the foreign matter judgment method is any one of an image classification method, a target detection method, an image preprocessing and feature extraction method, a machine learning method, an image segmentation method, and a feature extraction algorithm.

[0051] It should be understood that when the monitoring information is the second image information of the belt conveyor at the material drop port, the second image information can be used to determine whether the belt conveyor has spilled material during the material picking or stacking process. In this embodiment, the foreign matter judgment method can be used to determine whether there is a foreign matter in the preset area of ​​the second image information, wherein the preset area can be the area range where the material may appear when the belt conveyor has spilled material. When there is no foreign matter in the preset area of ​​the second image information, it can represent that the belt conveyor has not spilled material during the material stacking or material picking process. When there is a foreign matter in the preset area of ​​the second image information, it can represent that the belt conveyor has spilled material during the material stacking or material picking process, and then a second warning information can be generated, wherein the second warning information can be a warning information of the belt conveyor spilling material. The foreign matter judgment method can be any one of the image classification method, target detection method, image preprocessing and feature extraction method, machine learning method, image segmentation method, and feature extraction algorithm, and the image classification method, target detection method, image preprocessing and feature extraction method, machine learning method, image segmentation method, and feature extraction algorithm can all be methods for identifying foreign matter in images in the relevant technology, which will not be repeated here.

[0052] In a possible manner, generating target warning information according to the monitoring information includes: The friction sound signal between the belt and the roller of the belt conveyor during operation in the monitoring information is compared with the preset decibel value. When the decibel value corresponding to the friction sound signal is greater than the preset decibel value, a third warning information is generated, and the third warning information is determined as the target warning information.

[0053] It should be understood that when the monitoring information is a friction sound signal, the friction sound signal can be used to determine whether wear occurs between the belt and the roller. When wear occurs between the belt and the roller during the operation of the belt conveyor, the sound of friction will increase. Therefore, the decibel value corresponding to the friction sound signal can be compared with the preset decibel value. When the decibel value corresponding to the friction sound signal is greater than the preset decibel value, it can represent that wear occurs between the belt and the roller, and the generated third warning information can be a warning information of wear between the belt and the roller. When the decibel value corresponding to the friction sound signal is less than the preset decibel value, it can represent that no wear occurs between the belt and the roller.

[0054] In a possible manner, generating target warning information according to the monitoring information includes: The coal flow temperature on the belt in the belt conveyor in the monitoring information is compared with a preset temperature threshold, and when the coal flow temperature is greater than the preset temperature threshold, a fourth warning information is generated, and the fourth warning information is determined as the target warning information, wherein the preset temperature threshold is the coal flow temperature value when the belt conveyor is in normal operating state.

[0055] It should be understood that when the monitoring information is the temperature of the coal flow on the belt, it can be determined whether the belt conveyor is in a normal operating state based on the coal flow temperature and the preset temperature threshold, wherein the preset temperature threshold can be the coal flow temperature value when the belt conveyor is in a normal state. When the coal flow temperature is less than the preset temperature threshold, it can represent that the belt conveyor is in a normal operating state at this time. When the coal flow temperature is greater than the preset temperature threshold, it can represent that the belt conveyor has an abnormal operating condition. The fourth warning information generated can be a warning information that the temperature of the belt conveyor is too high. Among them, the preset temperature threshold can be eighty degrees, and this is not specifically limited in the embodiments of the present disclosure. At this time, the relevant personnel can control the operating state of the belt conveyor to a stopped operating state, thereby ensuring that the belt conveyor is not damaged.

[0056] For example, when the stacker-reclaimer generates target warning information, the target abnormal operation parameters can be obtained, and the target abnormal operation parameters can be applied to the subsequent step of determining the cause of the target fault. Among them, the target abnormal operation parameters can be the belt conveyor operating speed, belt conveyor operating power and belt conveyor operating efficiency, which are not specifically limited in the embodiments of the present disclosure.

[0057] For example, the target fault cause can be determined based on the target abnormal operation parameter and the preset fault association relationship. The preset fault association relationship can be a corresponding relationship between the abnormal operation parameter and the fault cause. A plurality of different abnormal operation parameters can correspond to one fault cause or different fault causes, and the embodiments of the present disclosure do not specifically limit this.

[0058] For example, the monitoring information, target warning information and target fault causes can be displayed on the display platform. The target warning information can be displayed in the form of sound and light alarm or voice alarm, which can remind relevant personnel that the operating parameters of the belt conveyor need to be adjusted, or the operating state of the belt conveyor can be controlled to stop running, thereby ensuring the stability of the belt conveyor operation and reducing the damage to the belt conveyor. Figure 3 As shown, by displaying the monitoring information on the display platform, relevant personnel can intuitively see the alarm location and corresponding target warning information during the operation of the stacker-reclaimer.

[0059] In a possible manner, the operation and maintenance method further includes: Determining real-time operating data of the stacker-reclaimer during operation; Inputting the real-time operation data into an optimal neural network model to obtain the remaining service life of the stacker-reclaimer, wherein the optimal neural network model is obtained by training the neural network model with historical operation data generated by the stacker-reclaimer during historical operation; The remaining usage time is displayed.

[0060] It should be understood that during the operation of the stacker and reclaimer, the use time of the stacker and reclaimer will be reduced as the equipment is used. Therefore, it is necessary to monitor the use time of the equipment. In this embodiment, the real-time operation data of the stacker and reclaimer during operation can be obtained, and the remaining use time of the stacker and reclaimer can be determined based on the real-time operation data. Among them, the real-time operation data may include the use time of each device in the stacker and reclaimer, the basic material of each device, the production date of each device, and the use date, etc. The real-time operation data can be input into the optimal neural network model to obtain the remaining use time of the stacker and reclaimer. And the remaining use time can be displayed on the display platform to remind relevant personnel of the service life of the stacker and reclaimer, so that the stacker and reclaimer can be maintained in time, which can increase the use time of the stacker and reclaimer.

[0061] In a possible manner, the stacker and reclaimer can also be monitored in real time, and the monitored information can be displayed. Among them, the monitored information can include different states of the stacker and reclaimer, such as operation, failure, shutdown, and the communication state between the corresponding controller of the stacker and reclaimer and each remote station. The state of the slewing system of the stacker and reclaimer, the slewing state includes slewing mode, slewing state, slewing angle, slewing inverter state, slewing limit limit, slewing area, slewing brake state, slewing encoder working state, slewing over-torque safety state, etc. The state of the hydraulic station system of the stacker and reclaimer, including the oil level state of the hydraulic station, the real-time pressure of the oil cylinder, the real-time temperature of the oil cylinder, the filter blockage switch state, the oil circuit switch state, the pitch angle, the pitch limit limit, the pitch horizontal correction limit, the pitch encoder working state, etc. The state of the cantilever belt conveyor of the stacker and reclaimer, including operation, standby, failure, deviation, emergency stop, blockage, slippage, real-time current of the motor, brake, and cantilever belt tension value. The status of the stacker-reclaimer's lubrication system, including the oil level of the lubrication cylinder, system fault signals, oil pressure signals, etc. The status of the stacker-reclaimer's electrical system, including the working / testing position of the incoming cabinet isolation trolley, the comprehensive protection status of the vacuum circuit breaker, and the various parameter values ​​of the electric energy metering system.
