Description

Technical Field

[0001] This invention belongs to the field of workshop monitoring technology, specifically relating to a workshop monitoring method, system, device, and storage medium. Background Technology

[0002] Materials for the workshop production line are supplied by transport workers driving tractor-trailers from the warehouse to the corresponding material picking racks at each workstation. Production workers then retrieve the materials at irregular intervals according to production needs. Throughout this process, the transport and unloading procedures of the transport workers, delivery times, and the picking times and material selection of the production workers all affect workshop production efficiency. However, in the current workshop operation, there is a lack of information monitoring for the transport workers' transport and unloading and the production workers' retrieval of materials from their workstations to the material picking racks. Most of the transport and retrieval is based on experience at fixed times, which prevents workshop managers from effectively managing the flow of materials and assessing workshop efficiency, thus affecting the evaluation and optimization of production benefits.

[0003] Therefore, there is an urgent need for a workshop supervision method based on location trajectory recognition to solve the problems of lack of digital monitoring in related technologies, difficulty in analyzing production bottlenecks, and optimization of workshop production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a workshop monitoring method, system, device, and storage medium to solve the aforementioned problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Firstly, a workshop supervision method is provided, including:

[0007] The system acquires the location and identification information of transportation workers, tractor units, and production workers monitored in real time by an indoor positioning system. The location and identification information includes the location tag ID, monitoring time, and location coordinates.

[0008] Based on the positioning and identification information of the transport workers and the tractor unit, the working status of the transport workers is determined, and the positioning tag ID, job type, job start time, job end time, target work station and flatbed trailer number of the transport workers are determined according to the corresponding working status of the transport workers.

[0009] Based on the location tag ID, job type, job start time, job end time, target workstation, and flatbed trailer number of the transport worker, generate the corresponding transport business information for the transport worker.

[0010] Based on the location identification information of production workers, determine the work status of production workers, and determine the location tag ID, job type, job start time and job end time of production workers in the corresponding work status.

[0011] Based on the location tag ID, job type, job start time, and job end time of the production worker, the corresponding picking business information for the production worker is generated.

[0012] Based on the aforementioned technology, by acquiring the location and identification information of transport workers, tractor units, and production workers, the working status of transport workers can be determined based on the location and identification information of transport workers and tractor units. Transport business information for transport workers is generated according to their respective working statuses. Similarly, the working status of production workers can be determined based on their location and identification information, and picking business information for production workers is generated according to their respective working statuses. This creates a transparent, end-to-end monitoring system for the operations of both transport and production workers in the flow of production materials. This provides data support for workshop managers to analyze bottlenecks in material transportation and replenishment and to optimize and upgrade processes, ultimately improving workshop production efficiency.

[0013] In one possible design, determining the working status of the transport worker based on the positioning and identification information of the transport worker and the tractor unit includes:

[0014] Based on the real-time monitored location coordinates of the transport workers and the tractor, determine whether the transport workers and the tractor are within the temporary storage area. If so, generate result 1; otherwise, generate result 0.

[0015] The first state result is obtained by subtracting the result generated at the previous monitoring time point from the result generated at the current monitoring time point for the transportation worker. A first state result of 1 indicates that the transportation worker has finished unloading operations, a first state result of -1 indicates that the transportation worker has started transportation operations, and a first state result of 0 indicates that the working status of the transportation worker has not changed.

[0016] In one possible design, the method further includes:

[0018] When the interval distance is greater than the set distance threshold, the operation type of the transportation worker is determined to be unloading. When the interval distance does not exceed the set distance threshold and the first state result is -1, the operation type of the transportation worker is determined to be transportation, and the start time and end time of the transportation operation type are determined. When the operation type of the transportation worker is transportation, the target workstation and flatbed trailer number are both the default value Not.

[0019] In one possible design, when the work type of the transport worker is unloading, the method further includes:

[0020] The movement trajectory of the transport workers is recorded based on their real-time location coordinates, and the movement trajectory includes several stopping points.

[0021] Extract the point of the station that is farthest from the tractor head in the movement trajectory as the first reference point, and draw the first reference circle with the first reference point as the center and the length of the flatbed trailer as the radius;

[0022] Mark all the resting points within the first reference circle, calculate the average coordinates of all resting points within the first reference circle, obtain the corresponding average coordinates, and determine the placement point based on the average coordinates;

[0023] Calculate the distance from the placement point to the tractor unit, divide the distance from the placement point to the tractor unit by the length of the flatbed trailer being towed by the tractor unit and round down to obtain the flatbed trailer number.

[0024] Calculate the distance from the placement point to each workstation, and determine the workstation with the closest distance as the target workstation;

[0025] Determine the corresponding monitoring time for each dwell point within the first reference circle, and sort the corresponding monitoring times for each dwell point based on the timeline to determine the start and end times of the unloading operation type.

[0026] In one possible design, determining the working status of production workers based on their location identification information includes:

[0027] Based on the real-time monitored location coordinates of production workers, determine whether transportation workers are within the corresponding workstation range. If so, generate result 1; otherwise, generate result 0.

[0028] The second state result is obtained by subtracting the result generated at the previous monitoring time point from the result generated at the current monitoring time point for the production worker. A second state result of 1 indicates that the production worker has started unloading operations, a second state result of -1 indicates that the production worker has finished unloading operations, and a second state result of 0 indicates that the production worker's working status has not changed.

[0029] In one possible design, the method further includes: during the process from the second state result being 1 to the second state result being -1, determining that the operation type of the production worker is unloading; during the process from the second state result being -1 to the second state result being 1, determining that the operation type of the production worker is picking; and determining the start time and end time of the unloading operation type of the production worker.

[0030] In one possible design, the method further includes:

[0031] When the second state result is -1, the picking trajectory of the production worker is recorded according to the real-time positioning coordinates of the production worker. The picking trajectory includes several picking points.

[0032] Using the midpoint of the corresponding material picking rack as the second reference point, and with the second reference point as the center and the length of the corresponding material picking rack as the radius, draw a second reference circle;

[0033] Mark all picking points within the second reference circle, determine the corresponding monitoring time for each picking point within the second reference circle, and sort the corresponding monitoring times for each picking point based on the timeline to determine the start and end times of the picking operation type.

[0052] Example 1:

[0053] This embodiment provides a workshop supervision method, such as... Figure 1 As shown, the method includes the following steps:

[0054] S101. Obtain the location identification information of transportation workers, tractor units and production workers monitored in real time by the indoor positioning system. The location identification information includes the location tag ID, monitoring time and location coordinates.

[0055] In practice, the workshop includes several workstations and several tractors. Each workstation is equipped with a material picking rack for production. Each tractor includes a tractor head and a flatbed trailer. The indoor positioning system includes indoor positioning base stations and positioning tags. The number of indoor positioning base stations deployed can be determined based on the installation height and the size of the workshop. Transport workers, tractor workers, and production workers in the workshop carry positioning tags while working. The ID of each positioning tag corresponds to the corresponding transport worker, tractor worker, and production worker. The positioning identification information of each positioning tag is collected in real time through the indoor positioning base stations, which is the positioning identification information corresponding to each transport worker, tractor worker, and production worker. The positioning identification information includes the positioning tag ID, monitoring time, and positioning coordinates.

[0056] S102. Based on the positioning and identification information of the transport worker and the tractor unit, determine the working status of the transport worker, and determine the positioning tag ID, job type, job start time, job end time, target work station and flatbed trailer number of the transport worker in the corresponding working status.

[0057] In practice, the working status of the transport worker is determined based on the positioning and identification information of the transport worker and the tractor unit. Specifically, this includes: determining whether the transport worker and the tractor unit are within the temporary storage area based on the real-time monitored positioning coordinates of the transport worker and the tractor unit; if so, generating result 1, otherwise generating result 0; subtracting the result generated at the previous monitoring time point from the result generated at the current monitoring time point to obtain the first state result. A first state result of 1 indicates that the transport worker has finished unloading operations, a first state result of -1 indicates that the transport worker has started transport operations, and a first state result of 0 indicates that the working status of the transport worker has not changed.

[0058] The process of determining the information of the corresponding work type, start time, end time, target work station, and flatbed trailer number for transport workers includes: determining the distance between the transport worker and the tractor based on the real-time monitored positioning coordinates of the transport worker and the tractor; when the distance is greater than a set distance threshold, the work type of the transport worker is determined to be unloading; when the distance is less than the set distance threshold and the first state result is -1, the work type of the transport worker is determined to be transportation, and the start time and end time of the transportation work type are determined. When the work type of the transport worker is transportation, the target work station and the tractor number are both default values ​​(Not).

[0059] When the work type of the transport worker is unloading, the movement trajectory of the transport worker is recorded according to the real-time positioning coordinates of the transport worker. The movement trajectory includes several stopping points. The stopping point farthest from the tractor unit in the movement trajectory is extracted as the first reference point. A first reference circle is drawn with the first reference point as the center and the length of the flatbed trailer as the radius. All stopping points within the first reference circle are marked, and the average coordinate of all stopping points within the first reference circle is calculated to obtain the corresponding average coordinate. The placement point is determined based on the average coordinate. The distance from the placement point to the tractor unit is calculated. The distance from the placement point to the tractor unit is divided by the length of the flatbed trailer towed by the tractor unit and rounded to obtain the flatbed trailer number. The distance from the placement point to each workstation is calculated, and the workstation closest to the placement point is determined as the target workstation. The corresponding monitoring time of each stopping point within the first reference circle is determined, and the corresponding monitoring time of each stopping point is sorted based on the timeline to determine the start time and end time of the unloading operation.

[0060] S103. Generate the corresponding transportation business information for the transportation worker based on the worker's location tag ID, job type, job start time, job end time, target workstation, and flatbed trailer number.

[0061] In practice, after processing and obtaining the location tag ID, job type, job start time, job end time, target workstation, and flatbed trailer number of the transport worker, the corresponding transport business information of the transport worker can be generated and output using the location tag ID, job type, job start time, job end time, target workstation, and flatbed trailer number. This allows workshop managers to keep track of the material flow operation information of the transport worker in real time.

[0062] S104. Based on the location identification information of the production workers, determine the work status of the production workers, and determine the location tag ID, job type, job start time and job end time of the production workers in the corresponding work status.

[0063] In specific implementation, the working status of production workers is determined based on their location identification information. Specifically, this includes: determining whether the transportation worker is within the corresponding workstation range based on the real-time monitored location coordinates of the production worker; if so, generating result 1, otherwise generating result 0; subtracting the result generated at the previous monitoring time point from the result generated at the current monitoring time point to obtain the second state result. A second state result of 1 indicates that the production worker has started unloading operations, a second state result of -1 indicates that the production worker has finished unloading operations, and a second state result of 0 indicates that the working status of the production worker has not changed.

[0064] The process of determining the corresponding job type, start time, and end time of a production worker includes: During the period from the second state result of 1 to the second state result of -1, determining the production worker's job type as unloading; during the period from the second state result of -1 to the second state result of 1, determining the production worker's job type as picking, and determining the start and end times of the unloading job. When the second state result is -1, recording the production worker's picking trajectory based on the real-time positioning coordinates of the production worker; the picking trajectory includes several picking points; using the midpoint of the corresponding material picking rack as the second reference point, and using the second reference point as the center and the length of the corresponding material picking rack as the radius, drawing a second reference circle; marking all picking points within the second reference circle, determining the corresponding monitoring time for each picking point within the second reference circle, and sorting the corresponding monitoring times of each picking point based on the timeline to determine the start and end times of the picking job.

[0065] S105. Generate picking business information for the corresponding production worker based on the worker's location tag ID, job type, job start time, and job end time.

[0066] In practice, after processing and obtaining the location tag ID, job type, job start time and job end time information of the production workers, the corresponding picking business information of the production workers can be generated and output using the location tag ID, job type, job start time and job end time information of the production workers, so that workshop managers can keep track of the material flow operation information of the production workers in real time.
