Additionally, features described with respect to some examples may be combined into other examples.

Referring to Figure 1, Figure 1 is a schematic flow chart of a carrier-based information tracing method provided by an embodiment of the present application. In the embodiment of this application, the method includes:

S101. Edit the sensor sequence on the production line and associate the serial number with the process location.

The execution subject of this application involves the vehicles, sensors and central control servers on the hanging production line. Among them, the vehicle is equipped with a sensor chip, which can be a passive electronic tag, and the sensor is used to detect the information emitted by the sensor chip, so that the information emitted by the sensor chip can be detected and received by the sensor within a certain range. The information stored in the sensor chip includes fixed information and written information. The fixed information is the identification information of the vehicle; the written information is the information of the clothing currently mounted on the vehicle, such as the category, material, number, etc. of the clothing. . It can be understood that the identification information is fixed information, and reference can be made to the unique identification code design of the sensor chip, which is used to identify the vehicle to distinguish it from other vehicles; the written information is written by staff or equipment at a specific location. The entry is related to the clothes transported by the vehicle; however, because the vehicle is used cyclically, the clothes mounted on the vehicle may be different during each cycle, and the corresponding data needs to be rewritten.

In one embodiment, various processes are laid out on the hanging production line. The carrier can complete the predetermined manufacturing process by running one cycle on the hanging production line, that is, the manufacturing of a piece of ready-made clothing. The length of the production line occupied by each process is different, and the number of sensors required is also different based on the needs of the process. When determining the length of each process, it can be divided according to the installation position of the sensor. Although there is a certain area amplification from the actual process position, there is no need to set up additional sensors to finely divide the process, which is more conducive to direct borrowing. The current hanging production line reduces additional additional costs.

In this application, step S101 specifically includes:

In the embodiment of the present application, the sensors are installed in corresponding process positions on the production line, which not only facilitates the division of process intervals, but also monitors the operation time of each process and reflects the operating efficiency of the workers. Based on the information of the person on duty at the process location, the person on duty can be quickly mapped according to the serial number of the sensor, and the person responsible for the corresponding process within the corresponding period can be confirmed.

In the embodiment of the present application, in a hanging production line, the various processes that the carrier goes through during operation are arranged in an orderly manner, and the serial numbers of the sensors on the production line should be unique, so that the carrier and the sensor The mapping relationship between devices is single and there is no duplication, which can effectively reflect the process of garments.

For each process in the production line, the process may be repeated. You can edit the code of the process location, associate the serial number of the sensor with the code of the process location, and upload it to the server for storage. Use the serial number of the sensor to compare the vehicle's The process progress during operation is identified and monitored.

When necessary, the code name can also be unique. By confirming the process location through the serial number, you can quickly respond to the staff in the corresponding area to confirm the authenticity and control the process progress of the vehicle.

S102. Obtain the detection information of each sensor on the production line during the operation of the vehicle, associate the detection information with the serial number of the corresponding sensor, and generate the production information of the vehicle according to the time stamp of the detection information. sequence.

In the embodiment of the present application, the induction signal between the carrier and the sensor is used as the monitoring data of the garment process process, and the sensor at the same position will perform induction detection on multiple passing carriers. If the signal received by the sensor is defined as a detection signal, then the sensor can detect corresponding data for each vehicle. The detection signal is formed by the response data emitted by the induction chip mounted on the vehicle. The detection information contains at least Including vehicle identification information and vehicle mounting information.

Therefore, when the vehicle is close to the sensor, the sensor can receive more detection information. The location where the detection information is generated is the location of the sensor, which means that a vehicle has moved here, and the vehicle is mounted there. The garment manufacturing process reaches here; the location of the sensor can reflect the process of the garment.

In one possible implementation, the process of the clothes mounted on the carrier arriving at the sensor position can be represented by the serial number of the sensor. When a carrier passes through multiple sensors, the process of the clothes can be represented by The serial numbers of the sensors are represented by time stamps, forming a generation sequence of the vehicle, which can represent the process of clothing. The specific steps include:

Update the production sequence in real time according to the operation of the carrier on the production line, and use the identification information of the carrier as an index entry of the production sequence;

In this application, the detection information of the sensor is formed based on the induction chip mounted on the vehicle. Within a certain distance, the sensor receives and detects the information emitted by the induction chip.

Multiple vehicles are running on the same production line, and each sensor can detect multiple vehicles. The detection information can be filtered and divided according to the identification information of the vehicle, and sorted by timestamp, thus based on the timeline. Generate the process progress of each vehicle; in the embodiment of the present application, the serial number of the sensor is used to sort and generate the production sequence of the vehicle, and the production sequence reflects the process progress of the vehicle during this operation.

It should be noted that in the actual production process, the carrier is recycled. Therefore, after the carrier completes one run on the production line, the carrier and the mounted garment have been separated and are no longer associated. At this time, then The relationship between the vehicle and the next garment manufacturing should be re-established. Specific steps include:

In one possible implementation, starting and ending points can be set on the production line. When the carrier runs to the starting and ending points, it is deemed to have completed a cycle. At the same time, the written data of the carrier is deleted and the identification information of the carrier is disconnected. The mapping relationship between related data allows the vehicle to re-establish data association with the garment production information in the next cycle run.

It can be understood that after the vehicle completes a cycle operation, there is no longer a necessary connection between the various data in this cycle operation and the vehicle, and can be directly disconnected. There is a necessary connection between the already formed production sequence and circulating batches of carriers and the corresponding garments. They are the actual production information in the garment manufacturing process and can form a traceability mark to facilitate the tracing of the production information of the corresponding garments.

S103. Match the production sequence with the predefined process confirmation sequence. When the production sequence has a missing serial number, send repair information. The repair information at least includes the identification information of the carrier and the missing serial number.

In the embodiment of the present application, the production sequence is generated based on the actual operation of the carrier. Therefore, before the carrier completes this cycle operation, the production sequence is increased in real time, the process of the process continues to advance, and the serial number is generated. It only increases gradually; it can be matched one-to-one with the serial number in the process confirmation sequence. If there is a lack of alignment, it means that there is a lack of serial number in the production sequence, and there may be a lack of process in the manufacturing of garments; if If there is no missing position, it means that the production sequence is complete and the garment manufacturing process is normal.

In an implementation manner, step S103 includes:

If there is no missing serial number in the corresponding area of the production sequence and the process confirmation sequence, then the process flow of the vehicle is normal;

In this application, based on the process flow of the production line, the serial numbers of the sensors at the corresponding process positions are sorted in order to form a response sequence of the corresponding sensors during normal operation of the carrier, and this is predefined as a process confirmation sequence. The production sequence added in real time only corresponds to a part of the process confirmation sequence, and the sequence number only needs to be matched to the interval where the process position is located. Since the process flow is determined, after the existing serial number of the vehicle is determined, the subsequent newly added serial number of the vehicle is clear in the process confirmation sequence. If the new serial number in the production sequence is consistent with the process confirmation sequence If there is any inconsistency, it means that there is a missing serial number in the corresponding area; otherwise, the process flow is normal.

It is understandable that the monitoring platform depends on the server settings to facilitate on-site confirmation by monitoring personnel.

In the embodiment of the present application, after receiving the repair information, it cannot be determined whether there is indeed a process defect, or it may be a sensor failure. Therefore, it also includes determining the nature of the missing serial number and repairing it. Specifically, Steps include:

Predefine the reference time-consuming range of each process;

In this application, when repairing a missing serial number, it is necessary to confirm it through on-site staff. Compared with direct on-site confirmation, in the embodiment of this application, the nature of the loss is inferentially judged based on the detention time, providing possibilities for maintenance personnel. This is helpful for maintenance personnel to quickly determine the fault point.

When the staff confirms that there is a missing process, they can make up for the missing process; when it is confirmed that the sensor is faulty, the sensor can be replaced and the missing serial number in the production sequence can be filled simultaneously to keep the garment process in a normal state. state. Understandably, the replacement sensor inherits the serial number of the failed sensor.

It should be noted that if the residence time is greater than the reference time-consuming range, it means that the process is delayed and inferential judgment cannot be made. The missing properties can be output as process delays. For delayed processes, reasonable judgments can be made based on the actual scenario. If a process delay occurs during the rest period, it means that the sensor is faulty and the corresponding function was not turned off in time; if a process delay occurs during the operating time, it means that there is a problem with the process. , personnel on duty should be reminded. If necessary, the upper limit of the reference time-consuming range can be appropriately extended to cope with emergencies and avoid process delays at the work station.

While the vehicle is running on the hanging production line, the real-time updates of the production sequence can be displayed on the monitoring platform. When the serial number is missing, it is possible to respond quickly, solve the problem, and avoid the shutdown of the entire production line.

S104. When the production sequence of the vehicle completely matches the process confirmation sequence, generate traceability information based on the production sequence and repair project.

In the embodiment of the present application, if the carrier completes one cycle of operation on the production line, it means that the garments carried by the carrier have completed all the processes in the hanging production line, and the production sequence and process confirmation sequence can be completely matched, and The serial number in the production sequence will no longer be added.

At this time, the association between the identification information of the vehicle and the production information of the clothes mounted in this cycle operation is disconnected, so as to establish a mapping relationship with the clothing production information in the next cycle operation and realize the cycle of the vehicle. use.

After the update of the production sequence is terminated, the cyclic batch of the vehicle can be associated with the index entry to form a traceability identification for this production operation, which can be traced back to the corresponding vehicle and batch, and the traceability identification will be regarded as this production operation. identification mark to facilitate the query call of the production sequence.

Based on the traceability identification, the production information of the clothes in the actual production process is traced and queried, and the traceability information is generated. The traceability information can be associated with the mounting information of the vehicle and thus associated with the corresponding clothes, which can be used for subsequent quality inspection. Data services are provided for information traceability/quality inspection of the clothing, customer inquiry/traceability of the production information of the clothing, etc.

It can be understood that after the production traceability information is obtained, the mounting information written in the sensor chip mounted on the vehicle can be overwritten and the next production operation can be carried out.

In an implementation manner, step S104 includes:

The mounting information of the vehicle in the detection information is retrieved, and the traceability information is generated based on the production information of the vehicle during this cycle and is associated with the mounting information.

In embodiments of the present application, identifiable labels can be set for clothing that has completed all processes and can be associated with traceability information. The identification information contained in the tag can be the category, material, number, etc. of the clothing. Preferably, it can be matched with the mounting information to quickly establish a mapping relationship with the traceability information.

The production information at least includes the executed process flow and the information of the personnel on duty, wherein the process flow includes the executed process flow and the repair project; it can be understood that the executed process flow can be a conventional process flow, or it can be It is a process flow with make-up work.

In the embodiments of this application, for the repair of sensor faults, the upper level monitoring fault should not be regarded as a repair project that affects the clothing process. It will not have an impact on the actual production information of the clothes and has nothing to do with the workers at the work station; Remedial work on missing processes should be regarded as repair items that affect the clothing process and added to the traceability information. Both the quality inspection post and the customer should have the right to know the true production information of the clothing.

It can be understood that the on-duty information at the process location at least includes on-duty personnel information and on-duty time periods. This data is fixed and can be queried and traced back to the responsible person. When performing make-up work, the location of the make-up work and the corresponding on-duty information should also be confirmed to effectively trace the new responsible person.

It can be understood that the cycle batch of the carrier includes the usage time and usage batch of the carrier.

Based on the above method, when the production sequence of a certain vehicle is stagnant at a certain node for a long time, the staff can conduct on-site confirmation, perform data repair, and perform maintenance on the corresponding vehicle or sensor.
