Description

Technical Field

[0001] The present application relates to the technical field of automatic control, and in particular, to a method, device, and electronic device for reminding of replacement of a brush driving device. Background Art

[0002] In a hanging production system, the hanging carriers on the production line are generally driven to move by bird hooks arranged on the track. Due to the certain length of the bird hook structure, the bird hook cannot be fully matched with the track structure at the track turning point, making it difficult to pass through the track turning point, which in turn affects the conveyance of the hanging carriers. For the above reasons, generally, a brush driving device is arranged beside the track turning structure, and a plurality of brushes move in a cycle on the device. The plastic hard hairs on the brushes are used to push the hanging carriers through the track turning structure. It can be seen that such a driving method completely depends on the pushing action of the brushes on the hanging carriers. As the usage time increases, the hairs in the brushes will be worn and fall off, which in turn affects the pushing force on the hanging carriers. Seriously, it may cause the brush driving device to be unable to drive the hanging carriers through the track turning point smoothly. Currently, generally, the brush driving device is inspected and replaced manually at regular intervals. However, such a method has low inspection efficiency, and since the hairs in the brushes are densely distributed, manual visual inspection may not accurately observe the hair loss and wear condition of the brushes, and thus it is impossible to determine which specific brush needs to be replaced.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application.

[0032] In the following description, the terms "first" and "second" are for descriptive purposes only and should not be construed as indicating or implying relative importance. The following description provides multiple embodiments of the present application, and different embodiments can be replaced or combined. Therefore, the present application can also be considered to include all possible combinations of the same and / or different embodiments described. Thus, if one embodiment includes features A, B, and C, and another embodiment includes features B and D, then the present application should also be considered to include embodiments containing one or more of all other possible combinations of A, B, C, and D, even though such embodiments may not be explicitly described in the following content.

[0033] The following description provides examples and does not limit the scope, applicability, or examples set forth in the claims. Changes can be made to the functions and arrangements of the described elements without departing from the scope of the present application. Various processes or components can be appropriately omitted, substituted, or added to each example. For example, the described method can be performed in a different order than the described order, and various steps can be added, omitted, or combined. In addition, the features described in some examples can be combined into other examples.

[0034] See Figure 1 , Figure 1 is a schematic flowchart of a replacement reminder method for a brush driving device provided by an embodiment of the present application. In the embodiment of the present application, the method includes:

[0035] S101. Obtain the current pressure data of each detection point corresponding to the array pressure sensor, where the array pressure sensor is used to detect the pressure data at the connection between the brush head and the bristles in the target brush.

[0036] The execution subject of the present application can be a cloud server.

[0037] In the embodiment of the present application, whether the brush head and the bristles in the brush are connected by means such as snap connection or bonding, in a state where they can be firmly connected, there must be mutual forces between the brush head and the bristles. In the present application, the array pressure sensor will be used to detect the pressure data at the connection between the brush head and the bristles, and the current connection state of the brush head and the bristles, that is, connected or separated, will be judged according to the detected current pressure data. Since the force is mutual, the array pressure sensor actually detects the force exerted by the bristles on the brush head during connection, so the array pressure sensor will be arranged on the brush head. By collecting the current pressure data of each detection point in the array pressure sensor, it is possible to judge the bristle dropping situation of each detection point.

[0038] Among them, the array pressure sensor can be arranged on the surface of the brush head connected to the bristles, or on the opposite side of the surface of the brush head connected to the bristles, or can be installed inside the brush head. And the array pressure sensor is detachably arranged on the brush head, so that when replacing the brush head with serious wear, only the array pressure sensor needs to be disassembled and arranged in the newly replaced brush head, without replacing the array pressure sensor together, saving costs.

[0039] In addition, when the brush is in the working state, the bristles will contact the vehicle on the hanging system track to realize the pushing of the vehicle by the bristles. In this case, due to the influence of the reaction force, the pressure data collected by the array pressure sensor does not represent the connection force between the brush head and the bristles in the normal state, and the pressure data may fluctuate greatly in a short time. Therefore, for the current pressure data that changes greatly in a short time, it is necessary to screen it out to ensure the accuracy of the subsequent calculation process.

[0040] S102. Determine the abnormal detection points where the current pressure data is lower than the preset pressure threshold, and calculate the proportion of the abnormal detection points in all the detection points.

[0041] In the embodiment of the present application, the detection point can be regarded as a circle with a certain area, rather than a point. That is to say, what a detection point detects is not the pressure exerted by a single bristle, but the combined pressure of several bristles within a certain area. When the bristles gradually wear out and fall off, the number of bristles exerting force on the brush head becomes smaller, resulting in a smaller current pressure data detected by the detection point. If the current pressure data is lower than the preset pressure threshold, it is considered that the hair loss problem at this point is serious, and this detection point is classified as an abnormal detection point. Then, the cloud server will calculate the proportion of each abnormal detection point in all the detection points to judge the overall wear condition of the brush, and further judge whether the brush needs to be replaced.

[0042] S103. When the proportion exceeds the preset proportion threshold, generate a replacement reminder message and send the replacement reminder message to a preset target terminal.

[0043] In the embodiment of the present application, if the calculated proportion exceeds the preset proportion threshold, it is considered that the brush is severely worn and needs to be replaced. At this time, a replacement reminder message will be generated and sent to the target terminal used by the maintenance personnel to remind the maintenance personnel to go and replace the brush. The target terminal can be a mobile terminal or a computer terminal.

[0044] In an implementable manner, the preset proportion threshold includes a first preset proportion threshold and a second preset proportion threshold, and the first preset proportion threshold is greater than the second preset proportion threshold;

[0045] When the ratio exceeds a preset ratio threshold, generating a replacement reminder message, including:

[0046] Calculating the density tendency data between the abnormal detection points;

[0047] When the density tendency data indicates a low density tendency, generating a replacement reminder message when the ratio exceeds the first preset ratio threshold;

[0048] When the density tendency data indicates a high density tendency, generating a replacement reminder message when the ratio exceeds the second preset ratio threshold.

[0049] In the embodiment of the present application, if the distribution of the abnormal detection points is relatively concentrated, that is, the positions where hair loss occurs are relatively concentrated, a large blank space will be generated in the brush. Compared with the situation where the distribution of the abnormal detection points is scattered, the concentrated situation will make it more difficult for the remaining bristles to exert a force on the carrier when the actual brush pushes against it. Therefore, in order to ensure that the brush can normally push against the conveying carrier, the density tendency data between each abnormal detection point is also calculated to determine whether the abnormal detection points are densely distributed. For the situation with a high density tendency of distribution, a lower second preset ratio threshold needs to be set to remind of brush replacement earlier.

[0050] In an implementable manner, the calculating the density tendency data between the abnormal detection points includes:

[0051] Calculating the number of adjacent abnormal points of each abnormal detection point respectively, and generating density tendency data based on the number of adjacent abnormal points;

[0052] Wherein, when the number of adjacent abnormal points corresponding to any one of the abnormal detection points is greater than a preset number threshold, the density tendency data indicates a high density tendency; when the number of adjacent abnormal points corresponding to all the abnormal detection points is not greater than the preset number threshold, the density tendency data indicates a low density tendency.

[0053] In the embodiment of the present application, since the array points in the array pressure sensor, that is, the detection points, are evenly distributed, eight detection points will be adjacent to each other around one detection point. The cloud server only needs to calculate and determine the number of adjacent abnormal points that are also abnormal detection points among the points adjacent to the abnormal detection points, and compare it with the preset number threshold to determine whether the abnormal detection points are densely distributed and generate density tendency data. As long as the number of adjacent abnormal points of an abnormal detection point is greater than the preset number threshold, it is considered that the density tendency of the abnormal detection point is high, otherwise it is considered that the density tendency is low.

[0054] In an implementable manner, the generating of the replacement reminder information includes:

[0055] Determine the identification number of the array pressure sensor, mark the target brush based on the identification number, and generate a replacement reminder information based on the identification number.

[0056] In the embodiments of the present application, a brush driving device contains several brushes. If only one brush has relatively serious hair loss and wear, only this brush needs to be replaced, and there is no need to replace the entire brush driving device. Therefore, it is also necessary to identify and distinguish each brush to help the maintenance personnel confirm which brush needs to be replaced. Specifically, each array pressure sensor is set with a different identification number. The replacement reminder information will include the identification number, and the target brush to be replaced will be marked. The maintenance personnel can quickly determine the brush to be replaced according to the mark and the identification number.

[0057] In an implementable manner, the method further includes:

[0058] Generate an abnormal point distribution image based on each of the abnormal detection points, and send the abnormal point distribution image to the target terminal.

[0059] In the embodiments of the present application, the cloud server can also generate an abnormal point distribution image according to the positions of the detected abnormal detection points. When the maintenance personnel actually arrive at the brush, they can recheck the wear condition of the brush according to the abnormal point distribution image to avoid mis-replacing a brush in good condition due to detection calculation errors.
