Description

Technical Field

[0001] This invention belongs to the field of steel pipe flaw detection, and specifically relates to a system, method, electronic device and storage medium for automatic selection of steel pipe process paths. Background Technology

[0002] In the production process of spiral submerged arc welded pipes, radiographic testing is a crucial quality control measure, playing a vital role in ensuring the safety and reliability of the pipelines. Radiographic testing technology uses X-rays or gamma rays to penetrate the steel pipe and detect internal defects such as cracks, porosity, and slag inclusions, thereby assessing the quality of the steel pipe. This technology is based on the difference in absorption of rays when passing through different materials, accurately revealing subtle changes in the internal structure of the steel pipe. However, in practice, the radiographic testing process faces some technical challenges, especially in the selection of the steel pipe path. Currently, most radiographic testing systems use manual or semi-automatic methods to set the testing path, meaning that technicians need to manually plan the movement route between the X-ray source and the steel pipe according to its specific specifications. This approach is not only time-consuming and labor-intensive but also prone to inconsistencies and errors in the testing results due to human factors.

[0003] Therefore, the existing steel pipe routes require manual planning and cannot be automatically selected, resulting in low work efficiency. Summary of the Invention

[0004] To address the aforementioned problems in the prior art, namely that existing steel pipe paths require manual planning and cannot be automatically selected, resulting in low work efficiency, this invention provides a system for automatic selection of steel pipe process paths, the system comprising:

[0005] The roller conveyor sensor is used to detect the position signal of the steel pipe and transmit the position signal of the steel pipe to the PLC master station;

[0006] The ranging sensor is used to detect the position signal of the traversing vehicle and transmit the position signal of the traversing vehicle to the PLC master station;

[0007] The control substation is used to acquire signals indicating whether the steel pipe is qualified and to transmit these signals to the PLC master station.

[0008] The PLC master station is used to send control signals to the roller conveyor frequency converter and the traverse car travel frequency converter based on the signal of whether the steel pipe is qualified, the position signal of the steel pipe and the position signal of the traverse car, so as to control the operation of the roller conveyor and the traverse car.

[0009] The roller conveyor is used to receive control signals from the PLC master station through the roller conveyor frequency converter, and to control the operation of the steel pipe based on the control signals.

[0010] The traverse car is used to receive control signals from the PLC master station via Profinet communication and control the movement of the steel pipe based on the control signals.

[0011] In a preferred embodiment, the control substation acquires a signal indicating whether the steel pipe is qualified and transmits the signal to the PLC master station, including:

[0012] The first roller conveyor transports the steel pipe to the first frame of the transverse car in front of the X-ray machine. The first sensor detects the position signal of the steel pipe to obtain the first signal, and transmits the first signal to the PLC master station.

[0013] The PLC master station transmits the first signal to the transverse car travel frequency converter; the first transverse car runs to the first conveyor roller based on the first signal. If there is a steel pipe on the first frame, the first transverse car transports the steel pipe to the first frame to wait for X-ray inspection; if there is no steel pipe on the first frame, the first transverse car transports the steel pipe to the first roller before the X-ray process.

[0014] When the second sensor at the first roller conveyor detects the second signal of the steel pipe, it transmits the second signal to the PLC master station. Upon receiving the second signal, the PLC master station controls the X-ray gate to open. At the same time, the PLC master station controls the second roller conveyor to transport the steel pipe to the X-ray process for inspection. After the inspection is completed, the control substation receives a signal indicating whether the steel pipe is qualified. The control substation then transmits the signal indicating whether the steel pipe is qualified to the PLC master station.

[0015] In a preferred embodiment, after the control substation transmits the signal indicating whether the steel pipe is qualified to the PLC master station, the following steps are included:

[0016] If the PLC master station receives a signal that the steel pipe is qualified, it controls the flaw detection trolley to move to the pipe delivery station and controls the second roller conveyor to transport the steel pipe to the first frame. After the second roller conveyor stops, the PLC master station controls the second transverse trolley to transport the steel pipe to the hydraulic pressing process. If the PLC master station receives a signal that the steel pipe is unqualified, it performs repair welding on the steel pipe.

[0017] In a preferred embodiment, if the PLC master station receives a signal that the steel pipe is qualified, it performs repair welding on the steel pipe, specifically including:

[0018] When the first welding stand allows pipe placement but the second welding stand does not, the PLC master station controls the second and third roller conveyors to transport the steel pipe to the first welding stand; when the third roller conveyor stops, the third transverse transfer car transports the steel pipe to the first welding stand process.

[0019] When the second welding stand allows pipe placement, and the first welding stand does not allow pipe placement, the PLC master station controls the second, third, and fourth roller conveyors to transport the steel pipe to the second welding stand. When the fourth roller conveyor stops, the fourth transverse transfer car transports the steel pipe to the second welding stand process.

[0020] In a preferred embodiment, the process of repairing the steel pipe by welding includes:

[0021] After the steel pipe is repaired on the first welding stand, the third transverse transfer car transports the steel pipe to the sixth roller conveyor. The sixth sensor detects the steel pipe signal and transmits it to the PLC master station. The PLC master station controls the sixth roller conveyor and the first roller conveyor to transport the steel pipe to the first stand of the transverse transfer car before X-raying, and the steel pipe continues to be inspected through the X-ray process.

[0022] After the steel pipe is welded on the second welding stand, it is transported to the fifth roller conveyor by the fourth transverse car. After the fifth sensor detects the signal of the steel pipe, it is transported to the first stand of the transverse car by the fifth roller conveyor, the sixth roller conveyor, and the first roller conveyor, and then inspected by X-ray.

[0023] A second aspect of the present invention provides a method for automatically selecting a steel pipe process path, based on the above-described system operation for automatically selecting a steel pipe process path, the method comprising:

[0024] The roller conveyor sensor detects the position signal of the steel pipe and transmits the position signal of the steel pipe to the PLC master station;

[0025] The ranging sensor detects the position signal of the traversing vehicle and transmits the position signal of the traversing vehicle to the PLC master station;

[0026] The control substation acquires the signal indicating whether the steel pipe is qualified and transmits the signal to the PLC master station.

[0027] The PLC master station sends control signals to the roller conveyor and the traverse car based on the signals indicating whether the steel pipe is qualified, the position of the steel pipe, and the position of the traverse car, thereby controlling the operation of the roller conveyor and the traverse car.

[0028] The roller conveyor and traverse car control the movement of the steel pipe based on control signals.

[0030] At least one processor; and

[0031] A memory communicatively connected to at least one of the processors; wherein,

[0044] This invention provides a system for automatic selection of steel pipe process paths, the system comprising:

[0045] To more clearly explain the automatic selection system for steel pipe process paths of the present invention, the following will be combined with... Figure 1 The steps in the embodiments of the present invention will be described in detail below.

[0046] The system for automatic selection of steel pipe process paths according to the first embodiment of the present invention is described in detail below:

[0047] The roller conveyor sensor is used to detect the position signal of the steel pipe and transmit the position signal of the steel pipe to the PLC master station;

[0048] The ranging sensor is used to detect the position signal of the traversing vehicle and transmit the position signal of the traversing vehicle to the PLC master station;

[0049] The control substation is used to acquire signals indicating whether the steel pipe is qualified and to transmit these signals to the PLC master station.

[0050] The PLC master station is used to send control signals to the roller conveyor frequency converter and the traverse car travel frequency converter based on the signal of whether the steel pipe is qualified, the position signal of the steel pipe and the position signal of the traverse car, so as to control the operation of the roller conveyor and the traverse car.

[0051] The roller conveyor is used to receive control signals from the PLC master station through the roller conveyor frequency converter, and to control the operation of the steel pipe based on the control signals.

[0052] The traverse car is used to receive control signals from the PLC master station via Profinet communication and control the movement of the steel pipe based on the control signals.

[0053] The roller conveyor sensor is used to detect the position signal of the steel pipe and transmit the position signal of the steel pipe to the PLC master station;

[0054] The ranging sensor is used to detect the position signal of the traversing vehicle and transmit the position signal of the traversing vehicle to the PLC master station;

[0055] The control substation is used to acquire signals indicating whether the steel pipe is qualified and to transmit these signals to the PLC master station.

[0056] In this embodiment, the process of the PLC master station acquiring and transmitting the signal indicating whether the steel pipe is qualified includes: a first roller conveyor transporting the steel pipe to the first frame of the transverse traverse carriage before X-ray inspection; a first sensor detecting the signal of the steel pipe to obtain a first signal and transmitting the first signal to the PLC master station; the PLC master station transmitting the first signal to the transverse traverse carriage's travel frequency converter; the first transverse traverse carriage moving to the first conveyor roller conveyor based on the first signal; if there is a steel pipe on the first frame, the first transverse traverse carriage transports the steel pipe to the first frame to await X-ray inspection; if there is no steel pipe on the first frame, the first transverse traverse carriage transports the steel pipe to the first roller conveyor before the X-ray process; when the second sensor at the first roller conveyor detects a second signal of the steel pipe, it transmits the second signal to the PLC master station; upon receiving the second signal, the PLC master station controls the X-ray door to open, and simultaneously controls the second roller conveyor to transport the steel pipe to the X-ray process for inspection; after inspection, the control substation obtains the signal indicating whether the steel pipe is qualified; the control substation transmits the signal indicating whether the steel pipe is qualified to the PLC master station.

[0057] In this embodiment, after the control substation transmits the signal indicating whether the steel pipe is qualified to the PLC master station, the process includes:

[0058] If the PLC master station receives a signal that the steel pipe is qualified, it controls the flaw detection trolley to move to the pipe delivery station and controls the second roller conveyor to transport the steel pipe to the first frame. When the second roller conveyor stops, the PLC master station controls the second transverse trolley to transport the steel pipe to the hydraulic pressing process. If the PLC master station receives a signal that the steel pipe is unqualified, it repairs the steel pipe by welding.

[0059] In this embodiment, if the PLC master station receives a signal that the steel pipe is unqualified, it will perform repair welding on the steel pipe. Specifically, this includes: when the first repair welding stand allows pipe placement but the second repair welding stand does not allow pipe placement, the PLC master station controls the second and third roller conveyors to transport the steel pipe to the first repair welding stand; when the third roller conveyor stops, the third transverse transfer vehicle transports the steel pipe to the first repair welding stand process; when the second repair welding stand allows pipe placement but the first repair welding stand does not allow pipe placement, the PLC master station controls the second, third, and fourth roller conveyors to transport the steel pipe to the second repair welding stand; when the fourth roller conveyor stops, the fourth transverse transfer vehicle transports the steel pipe to the second repair welding stand process.

[0060] In this embodiment, the process after welding the steel pipe includes: after welding the steel pipe on the first welding stand, the third traverse car transports the steel pipe to the sixth roller conveyor. The sixth sensor detects the steel pipe signal and transmits it to the PLC master station. The PLC master station controls the sixth roller conveyor and the first roller conveyor to transport the steel pipe to the first stand of the traverse car before X-raying, where the steel pipe continues to be inspected through the X-ray process. After welding the steel pipe on the second welding stand, the fourth traverse car transports the steel pipe to the fifth roller conveyor. After the fifth sensor detects the steel pipe signal, the fifth roller conveyor, the sixth roller conveyor, and the first roller conveyor transport the steel pipe to the first stand of the traverse car, where the steel pipe continues to be inspected through the X-ray process.

[0061] The PLC master station is used to control the operation of the roller conveyor and the transverse car based on the signals of whether the steel pipe is qualified, the signals of the steel pipe, and the signals of the transverse car.

[0062] Roller conveyors are used to control the movement of steel pipes based on signals from the PLC master station.

[0063] The traverse car is used to control the movement of steel pipes based on signals from the PLC master station.

[0064] To clearly illustrate the automatic selection system for steel pipe flow paths of this application, this embodiment also provides the control principle of the automatic selection system for steel pipe flow paths, which specifically includes:

[0065] After the steel pipe is transported from the first roller conveyor to the first stand of the transverse traverse carriage before X-ray inspection, the first sensor detects the steel pipe signal as the first signal S1. Based on the first signal S1, the first transverse carriage moves to the first roller conveyor. If there is a steel pipe on the stand, the first transverse carriage transports the steel pipe to the first stand to await X-ray inspection; if there is no steel pipe on the stand, the first transverse carriage transports the steel pipe to the first roller conveyor before the X-ray process. The second sensor detects the steel pipe signal S2, the X-ray door opens, the second roller conveyor rotates, and the steel pipe is transported to the X-ray process for inspection. After inspection, if the signal is "qualified" S3, the flaw detection carriage moves to the pipe delivery station, the second roller conveyor transports the steel pipe to the stand, and S4 = S2 & S3 & S5, where S5 is the stop signal for the second roller conveyor. Based on the S4 signal, the second transverse carriage transports the current steel pipe to the hydraulic pressure process.

[0066] If the signal is "unqualified" (S6), the flaw detection trolley moves to the pipe delivery station, and the third and fourth sensors detect signals S7 and S8 respectively. The first and second welding stands's allowable pipe delivery signals are S9 and S8 respectively. 10 ,

[0067] When the first welding stand allows for pipe placement The PLC control system is based on S 11 The signal controls the second and third roller conveyors to transport the steel pipe to the first welding stand. 12S is the stop signal for the third roller conveyor. 13 =S7&S 12 The third transverse moving vehicle 3 according to S 13 The signal will transport the current steel pipe to the first welding stand process. When the second welding stand allows pipe placement, The PLC control system is based on S 14 The signal controls the second, third, and fourth roller conveyors to transport the steel pipe to the second welding stand. 15 S is the stop signal for the fourth roller conveyor. 16 =S8&S 15 The fourth transverse moving car according to S 16 The signal will transport the current steel pipe to the second welding stand process.

[0068] After the steel pipe is welded on the first welding stand, it is transported by the third transverse transfer car to the sixth roller conveyor, where the sixth sensor detects the steel pipe signal S. 17 Afterwards, the steel pipe is transported by the sixth roller conveyor and the first roller conveyor to the first transverse transfer car platform for re-inspection. After the steel pipe is repaired and welded on the second welding platform, it is transported by the fourth transverse transfer car to the fifth roller conveyor. After the fifth sensor detects the signal of the steel pipe, it is transported by the fifth roller conveyor, the sixth roller conveyor, and the first roller conveyor to the first platform next to the first transverse transfer car for re-inspection.

[0069] This application adopts the Profinet distributed master-slave control mode, with a Siemens S7-1500 PLC as the master station, mainly responsible for real-time acquisition of the position data of the transverse transfer car, acquisition of roller conveyor sensor signals, input and output signal control, logic operation and control of the actuators; the slave station consists of an ET200MP, a laser rangefinder, a frequency converter and a touch screen system, mainly responsible for remote operation and control of the roller conveyor, flaw detection trolley and transverse transfer car; the touch screen system is configured using TIA Portal software to complete the setting of process parameters and real-time monitoring of equipment operating status.

[0070] Sensors one through six are all conveyor roller sensors used to detect the presence or absence of signals from the steel pipe, enabling automatic control of different conveying paths for the steel pipe. Mirror-reflective sensors are employed; the sensor's emitted beam is detected by a reflector. The sensors and reflectors are mounted on both sides of the roller conveyor to accommodate variations in the steel pipe diameter.

[0071] This avoids the workload of adjusting the vertical height of inductive sensors according to different steel pipe diameters due to the limited detection distance, and also avoids the drawback of diffuse reflection sensors being prone to generating false signals, thus realizing the automatic and stable operation of steel pipes along different conveying paths.
