[0043] The purpose of the present invention is to provide a method for realizing the tracking of the P&F chain coiling in a high-speed wire rod production line through video recognition of hook numbers, so as to improve the tracking accuracy and efficiency in the wire rod production process, reduce manual intervention, and improve product quality.

[0044] Figure 1 The system structure diagram of the present invention is shown as Figure 1 As shown, the present invention mainly consists of the following parts:

[0045] 1. PLC signal acquisition module: During the process from the start of coiling to the unloading of the coil, the positions of the entire tracking production line include: coiling

[0046] (rolling_station_pinch1), the 1# packing position (package_station1_pinch1), the 2# packing position

[0047] (package_station2_pinch1), the weighing position (weight_station1_detect), the 1# coil unloading position

[0048] (unload_station1_pinch1), the 2# coil unloading position (unload_station2_pinch1). At each location, a first-level automation device collects the device values in real time, and the second-level PLC signal acquisition module continuously monitors the device position values in real time, and at the same time sends the position names and values to the video acquisition module and the coiling tracking logic processing module.

[0049] 2. Video acquisition module: The video acquisition module mainly receives the position signals and values sent by the PLC signal acquisition module, then determines whether to send a photographing instruction and which camera to send the photographing instruction to. Finally, it sends the photographing result to the video recognition and analysis module.

[0050] There are 5 terminal cameras in the video acquisition module, which are respectively deployed at the coiling station (rolling_station_pinch1), the 1# packing position (package_station1_pinch1), the 2# packing position (package_station2_pinch1), the weighing position (weight_station1_detect), the 1# uncoiling position (unload_station1_pinch1), and the 2# uncoiling position (unload_station2_pinch1). When the video acquisition module receives a video acquisition signal, it judges which camera should be sent a photographing instruction by analyzing the point name and value sent by the PLC signal acquisition module. When the received point value is 1, a photographing instruction is sent to the camera installed at the corresponding point (device).

[0051] 3. Video recognition and analysis module: Receives the high-definition pictures sent by the video acquisition module and the camera positions (the 5 positions tracked above), performs video recognition on the received photos to obtain the hook number. Calls the interface of the coiling tracking data center module to update the hook number value of the hook number encoding corresponding to this position. When the hook number encoding exists, the corresponding hook number value is updated. Among them, the hook number encoding corresponding to coiling is position1HookCode, the hook number encoding corresponding to the 1# packing is position2HookCode1, the hook number encoding corresponding to the 2# packing is position2HookCode2, the hook number encoding corresponding to weighing is position3HookCode, the hook number encoding corresponding to the 1# uncoiling is position4HookCode1, and the hook number encoding corresponding to the 2# uncoiling is position4HookCode2

[0052] 4. Coiling tracking logic processing module: The coiling tracking logic processing module is the core tracking logic of this patent. Through the signal acquisition of the PLC signal acquisition module, B, and C, and video recognition processing, after the judgment of the tracking logic, finally updates the existing coiling tracking logic or creates a new coiling tracking data. After receiving the point signal and value of the PLC signal acquisition module, first call the video recognition and analysis module to obtain the latest video analysis result (i.e., the hook number value), and then enter the tracking processing logic. The specific processing logic is as follows:

[0053] 4-1: If the signal point sent by the PLC signal acquisition module is the coiling signal rolling_station_pinch1 and the value is 1, then go to the coiling tracking data center module to find the hook number value position1HookCode_value corresponding to the encoding position1HookCode, and find in the coiling tracking data center module that the coiling status is 0 and the uncoiling status is 0

[0054] (Uncoiling not completed), for the data with the hook code value of position1HookCode_value, if there is no data that meets the matching conditions, a new tracking data will be created in the coiling tracking data center. Set the coiling status to 1 (coiling in progress), the hook code to position1HookCode_value, the coiling start time and other information. Otherwise, discard it.

[0055] 4-2: If the signal point sent by the PLC signal acquisition module is the 1# packing signal package_station1_pinch1 and the value is 1, go to the coiling tracking data center module to find the corresponding hook code value position2HookCode1_value for the code position2HookCode1. In the coiling tracking data center module, find the data with the coiling status of 1, the packing 1 status of 0 (not packed), and the hook code value of position2HookCode1_value. If there is data that meets the matching conditions,

[0056] then update the packing 1 status of this data to 1, the packing position to 1, and the hook code to position2HookCode1_value,

[0057] the packing start time and other information. Otherwise, discard it.

[0058] 4-3: If the signal point sent by the PLC signal acquisition module is the 2# packing signal package_station2_pinch1 and the value is 1, go to the coiling tracking data center module to find the corresponding hook code value position2HookCode2_value for the code position2HookCode2. In the coiling tracking data center module, find the data with the coiling status of 1, the packing 2 status of 0 (not packed), and the hook code value of position2HookCode2_value. If there is data that meets the matching conditions,

[0059] then update the packing 1 status of this data to 1, the packing position to 2, and the hook code to position2HookCode2_value,

[0060] the packing start time and other information. Otherwise, discard it.

[0061] 4-4: If the signal point sent by the PLC signal acquisition module is the weighing signal weight_station1_pinch1 and the value is 1, then go to the coiling tracking data center module to find the hook number value position3HookCode_value corresponding to the code position3HookCode. In the coiling tracking data center module, find the data with the packing 1 or packing 2 status being 1, the weighing status being 0 (not weighed), and the hook number value being position3HookCode_value. If there is data that meets the matching conditions, then update the weighing status of this data to 1, the hook number to position3HookCode_value, and information such as the weighing start time. Otherwise, discard it.

[0062] 4-5: If the signal point sent by the PLC signal acquisition module is the 1# uncoiling signal unload_station1_pinch1 and the value is 1, then go to the coiling tracking data center module to find the hook number value position4HookCode1_value corresponding to the code position4HookCode1. In the coiling tracking data center module, find the data with the weighing status being 1, the uncoiling status being 0 (not uncoiled), and the hook number value being position4HookCode1_value. If there is data that meets the matching conditions, then update the uncoiling status of this data to 1, the uncoiling position to 1, and the hook number to position4HookCode1_value,

[0063] and information such as the uncoiling start time. Otherwise, discard it.

[0064] 4-6: If the signal point sent by the PLC signal acquisition module is the 2# uncoiling signal unload_station2_pinch1 and the value is 1, then go to the coiling tracking data center module to find the hook number value position4HookCode2_value corresponding to the code position4HookCode2. In the coiling tracking data center module, find the data with the weighing status being 1, the uncoiling status being 0 (not uncoiled), and the hook number value being position4HookCode2_value. If there is data that meets the matching conditions, then update the uncoiling status of this data to 1, the uncoiling position to 2, and the hook number to position4HookCode2_value,

[0065] and information such as the uncoiling start time. Otherwise, discard it.

[0066] 5. Coiling Tracking Data Center Module: The coiling tracking data center module mainly saves and records each coiling tracking information, receives the data processed by the coiling tracking logic processing module, and secondly saves the hook number code and the corresponding latest hook number value.

[0067] The receiving video recognition and analysis module calls the interface to update the hook number value corresponding to a certain hook number code.

[0068] The method of the present invention is to respectively collect video images of the working positions on the entire tracking production line through the video acquisition module and the video recognition and analysis module, and through video recognition and analysis, obtain the point position information and hook number information at the corresponding positions, and then combine the comprehensive analysis of the coiling tracking logic processing module and the coiling tracking data center module. Obtain all tracking information of each coiling on the entire coiling tracking production line.

[0069] A main loop process is as follows:

[0070] a) The PLC signal acquisition module collects a signal. Assuming the signal point position is the start of coiling rolling_station_pinch1, and

[0071] the value is 1, indicating that coiling starts at the coiling position. Send this message body to the video acquisition module and the coiling tracking logic processing module.

[0072] b) The video acquisition module receives the message body sent by the PLC signal acquisition module, obtains that the camera position is the coiling position, triggers the camera at this position to take a photo, and then sends the taken high-definition photo and the point position information to the video recognition and analysis module together.

[0073] c) The video recognition and analysis module receives the message body sent by the video acquisition module, performs video recognition and analysis on the received high-definition photo, obtains the hook number value position1HookCode_value, and then according to the point position

[0074] rolling_station_pinch1 obtains the hook number code as position1HookCode. Then, through the interface, actively update the hook number value corresponding to the hook number code position1HookCode stored in the coiling tracking data center module to

[0075] position1HookCode_value.

[0076] d) The coiling tracking logic processing module receives the message body sent by the PLC signal acquisition module, calls the coiling tracking data center module to obtain the hook number value position1HookCode_value with the hook number code of position1HookCode, and then queries the hook number value in the tracking information table of the coiling tracking data center module according to this hook number value

[0077] For the position1HookCode_value where the coiling status is 0 (coiling not started) and the uncoiling status is 0, if there is data that meets the matching conditions, it indicates that this hook number has not been used. Then, a new tracking data is created in the coiling tracking data center module, setting the coiling status in this message body to 1 (coiling started), the coiling start time (current time), and the hook number value to position1HookCode_value.

[0078] As described above, receiving signals from the PLC signal acquisition module to the coiling tracking data center module for storing tracking messages, a complete process is completed. When the point information received by the module is for packing, weighing, or uncoiling, the processing process is the same, only the judgment conditions are different. The judgment logics for different points have been described in the main parts 4-1 to 4-6. All scenarios will not be elaborated here.

[0079] The present invention introduces the combination of video recognition of hook numbers and tracking algorithms, a method for coiling tracking of the P&F chain in a high-speed wire rod production line. Due to its real-time performance and accuracy, it greatly reduces human intervention, can remotely implement production scheduling guidance, and improves production efficiency.
