[0019] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0020] like Figure 1 As shown, a conveyor system with a twitching detection function for a steel wire core conveyor belt joint of the present invention comprises: a twitching detection module, the twitching detection module comprises a plurality of sensors and a twitching detection chip, the plurality of sensors are installed under the conveyor belt and perform online detection on a plurality of parts of the conveyor belt to obtain detection result data. In practice, the sensor may be a flaw detection sensor, which may be used to detect the magnetic conductivity of the steel wire core, and the change in the magnetic conductivity of the steel wire core may reflect the twitching of the conveyor belt joint.

[0021] Environmental parameter acquisition module, the environmental parameter acquisition module is used to collect environmental parameters of the conveyor system during operation. Environmental parameters include jitter parameters and ambient temperature. In the actual production process, if the equipment shakes violently or the ambient temperature changes greatly, it will significantly affect the test result data, thus causing inaccurate test results. The jitter parameter can be the vibration frequency. Generally, the larger the jitter parameter, the greater the difference between the ambient temperature and the normal temperature, and the greater the impact on the test result data.

[0022] Based on this, a test result calibration module is set, and the test result calibration module is used to calibrate the test result data according to the environmental parameters to obtain the calibrated test result data. Specifically, the calibrated test result data is generated by the following steps: according to the jitter parameters and the ambient temperature, the corresponding calibration coefficient is queried in a pre-configured calibration coefficient query table; the test result data is calibrated according to the calibration coefficient to obtain the calibrated test result data. The calibration coefficient corresponding to different jitter parameters and ambient temperatures can be obtained through a large number of experimental tests. Then the calibration coefficient is calibrated with the test result data to obtain the calibrated test result data. Specifically, the calibration coefficient is multiplied by the test result data to obtain the calibrated test result data.

[0023] Afterwards, the calibration test result data is sent to the twitch detection chip, and the twitch detection chip generates a twitch detection result based on the calibration test result data. The twitch detection result includes multiple wire rope number groups where twitching occurs and the twitching distance corresponding to each wire rope number group; an adaptive treatment plan generation module is used to generate a corresponding treatment plan based on the twitch detection result. Specifically, the calibration test result data is input into the twitch recognition model to obtain the twitch detection result. The twitch recognition model is a fully connected artificial neural network.

[0024] Optionally, the treatment plan is generated by the following steps: counting the number of wire rope number groups whose twitching distance is greater than a first preset twitching distance threshold among multiple wire rope number groups that have twitched and taking it as a first number, if the first number is greater than the first preset threshold, generating a first treatment plan representing replacement of the conveyor belt; if the first number is less than or equal to the first preset threshold, determining whether there are at least two adjacent wire rope number groups among the multiple wire rope number groups that have twitched, if so, determining the position to be repaired in the conveyor belt based on the at least two adjacent wire rope number groups, and generating a second treatment plan representing repairing the position to be repaired.

[0025] Optionally, the present invention provides a conveyor system with a wire rope core conveyor belt joint twitching detection function, and also includes: a disposal evaluation module, the disposal evaluation module is used to obtain an updated twitching detection result from the twitching detection chip after the disposal plan is executed; determine whether the updated twitching detection result meets the pre-set disposal effect evaluation condition; if the updated twitching detection result meets the pre-set disposal effect evaluation condition, then generate a disposal plan score based on the updated twitching detection result and the twitching detection result, add the disposal plan score to the disposal plan, and obtain a reference disposal plan.

[0026] In some embodiments, the environmental parameters of the conveyor system during operation are collected through the environmental parameter collection module, and the detection result data is calibrated through the environmental parameters to obtain calibrated detection result data, thereby making the twitching detection result more accurate; in addition, based on the twitching detection result, a corresponding disposal plan is generated to effectively guide the workers' operation.

[0027] In some embodiments, in order to further solve the second technical problem described in the background technology part, that is, "as the running time of the conveyor system continues to increase, the conveyor belts installed in the conveyor system gradually become non-standard conveyor belts, and the detection accuracy of the joint twitching detection function of the existing conveyor system for non-standard conveyor belts is significantly reduced", in some embodiments of the present invention, the twitching detection result is generated by the following steps: when the conveyor system hits any monitoring condition in the monitoring condition group, it enters the non-standard detection mode, and the monitoring condition group includes that the running time of the conveyor system is greater than the preset time; the number of maintenance times of the conveyor belt in the conveyor system is greater than the preset number threshold; the difference between the magnetic permeability of the steel wire rope core of the conveyor belt and the standard magnetic permeability is greater than the preset difference threshold; in the non-standard detection mode, the monitoring condition hit by the conveyor system is determined as the target monitoring condition. If the target monitoring condition is the conveyor If the number of maintenance times of the conveyor belt in the system is greater than a preset threshold, multiple historical maintenance records of the conveyor belt are obtained, each of which includes a maintenance location; each maintenance location is determined as a key monitoring location, and a first image acquisition instruction is generated according to the location information of the key monitoring location, and the first image acquisition instruction is sent to the X-ray machine so that the X-ray machine acquires an X-ray image and sends it to the image analysis platform; if the target monitoring condition is that the operating time of the conveyor system is greater than the preset time, a second image acquisition instruction is generated, and a second image acquisition instruction is generated; the image analysis platform receives the X-ray image to identify and match the wire rope joints, obtains multiple wire rope joint groups, and calculates the distance between the two wire rope joints in each wire rope joint group to obtain the actual distance; the actual distance is compared with the standard distance to obtain the number of twitching wire ropes and generate a conveyor belt joint twitching detection result.

[0028] In some embodiments, by setting a monitoring condition group and a non-standard detection mode, targeted detection of non-standard conveyor belts can be achieved, thereby improving the detection accuracy of non-standard conveyor belts.

[0029] In some embodiments, in order to further solve the third technical problem described in the background technology part, namely, "in the non-standard detection mode, the joint twitching detection results are obtained by analyzing the X-ray image. In practice, the joint types of conveyor belts are different, and configuring the same detection scheme for different joint types will lead to a decrease in the accuracy of the detection results", in some embodiments of the present invention, the twitching detection chip is also used to perform the following processing steps: for each of the multiple wire rope joint groups, according to the coordinates of the upper joint and the coordinates of the lower joint, the coordinates of the center point of the wire rope joint group are determined and recorded as the center point coordinates; according to the joint type of the conveyor belt, the number of joint layers is determined; the number of joint layers is taken as the target number, and the multiple joint groups are clustered according to the vertical coordinates in the center point coordinates to obtain the target number of clusters, and the multiple joint groups in each cluster belong to the joint group of the same layer; for the multiple wire rope joint groups in each cluster, they are arranged according to the horizontal coordinates. A sequence is generated to generate a wire rope joint group sequence corresponding to each cluster, and a target number of wire rope joint group sequences are obtained; a pre-taken standard X-ray image and a standard wire rope joint group list corresponding to the standard X-ray image are obtained, the standard wire rope joint group list includes multiple standard wire rope joint groups in the standard X-ray image and associated information of each wire rope joint group, and the associated information includes a standard joint distance; for the wire rope joint group sequence, each wire rope joint group is traversed in turn; for each wire rope joint group, a matching standard wire rope joint group is determined in the standard wire rope joint group list, and the difference between the actual distance of the wire rope joint group and the standard joint distance of the matching standard wire rope joint group is determined as the twitching distance, and it is judged whether the twitching distance is greater than a preset difference threshold. If the twitching distance is greater than the preset difference threshold, the wire rope joint group is determined as a wire rope joint group that has twitched, and the number of wire rope joint groups that have twitched is counted.

[0030] The matching standard wire rope joint group is determined by the following steps: for each wire rope joint group, determine the next wire rope joint group after the wire rope joint group in the wire rope joint group sequence and record it as the adjacent wire rope joint group, determine the lateral distance between the wire rope joint group and the adjacent wire rope joint group and record it as the actual lateral distance; determine the Euclidean distance between the wire rope joint group and each standard wire rope joint group in the standard wire rope joint group list, and screen out multiple standard wire rope joint groups whose Euclidean distance is less than a preset distance threshold as multiple candidate standard wire rope joint groups; determine the lateral distance between each candidate standard wire rope joint group and the adjacent standard wire rope joint group respectively, and use it as the lateral distance of each candidate standard wire rope joint group; determine the candidate standard joints whose lateral distances match the actual lateral distances in the multiple candidate standard wire rope joint groups, and use them as the matching standard wire rope joint groups.

[0031] In some embodiments, different joint types exist in the actual production process, and different joint types correspond to different joint layers. On this basis, clustering is performed based on the vertical coordinate, so that the joint group is layered, thereby achieving accurate detection. In addition, by screening out matching standard wire rope joint groups through lateral distance, the standard wire rope joint group can be determined more accurately, ultimately improving the accuracy of the detection result.

Those skilled in the art should understand that the scope of the invention involved in the present invention is not limited to the technical solutions formed by the specific combination of the above technical features, but also should cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept.
