[0024] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0025] With the rapid development of industrial automation, automated production systems are rapidly being applied in various industries, such as air conditioning, automotive manufacturing, and the food industry. Most automation is achieved through the coordination of different PLC models. For example, in a high-frequency welding test platform, due to the complex system setup, two different PLCs are typically required to perform servo control on eight axes. However, the welding test platform's peripheral devices have numerous external signals, which requires multiple wiring connections between different PLCs. This wiring is often done manually, which is tedious and labor-intensive, resulting in a low level of automation in signal exchange between different PLCs.

[0026] Based on this, touch screens, as a new type of computer input device, are ubiquitous in automated production systems. They are currently the simplest, most convenient, and most natural way to interact. The technical solution of this invention uses a touch screen as a medium and employs its macro function to control different PLCs. This solves the problems of cumbersome manual wiring and low automation, making the interaction between the first and second controllers more intelligent and improving the automation level of signal exchange.

[0027] According to an embodiment of the present invention, an embodiment of a signal communication method for welding testing equipment is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0028] In this embodiment, a signal communication method for welding test equipment is provided, which can be used for welding test equipment. Figure 1 FIG. 1 is a flow chart of a signal communication method for a welding test device according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0029] S11, obtaining control signals of a first controller and a second controller, wherein the first controller and the second controller are of different models.

[0030] The first controller and the second controller are programmable logic controllers, and the first controller and the second controller are of different types.

[0031] The welding test equipment primarily consists of a first controller, a second controller, a servo module, and a touch screen. It primarily performs welding on components, such as a four-way valve. The first controller, the second controller, and the touch screen are all connected to a network switch. The touch screen communicates with the first and second controllers via the Enterprise Information Portal (EIP), while the servo module communicates with the first and second controllers via a bus.

[0032] The control signal is used to indicate the current status of the first controller and the second controller. During the interaction between the first controller and the second controller, the welding test equipment can obtain the control signal sent or received by the first controller and the control signal sent or received by the second controller through the network switch.

[0033] S12: Control the first controller and the second controller to interact with each other via control signals based on the touch screen macro instruction.

[0034] Touchscreen macros are an inherent feature of the touchscreen. Using the touchscreen as a medium between the first and second controllers, touchscreen macros are used to define information exchange between them. Specifically, the first and second controllers must cooperate to control the servo module. Technicians can use touchscreen macros to establish a data transmission channel between the first and second controllers. Accordingly, the welding test equipment's touchscreen can respond to the technician's configuration and utilize the touchscreen macro's functional program to complete the exchange of control signals between the first and second controllers.

[0035] S13, determining the control states of the first controller and the second controller according to the interaction result of the control signal.

[0036] The first controller and the second controller of the welding test equipment interact with each other in terms of control signals, and control the movement of the servo module according to the interaction results of the control signals, thereby determining the control state of the servo module by the first controller and the control state of the servo module by the second controller. For example, the first controller can control the servo model to move forward and backward and up and down, and the second controller can control the left and right movement of the servo module.

[0037] The signal communication method for welding testing equipment provided in this embodiment constructs signal interaction between the first controller and the second controller through touch screen macro instructions, thereby realizing control of the first controller and the second controller. This eliminates the need for manual wiring between the first controller and the second controller, solves the problems of cumbersome manual wiring and low degree of automation, reduces manual labor intensity, makes the interaction between the first controller and the second controller more intelligent, and improves the degree of automation of signal interaction.

[0038] In this embodiment, a signal communication method for welding test equipment is provided, which can be used for welding test equipment. Figure 2 FIG. 1 is a flow chart of a signal communication method for a welding test device according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0039] S21, obtaining control signals of the first controller and the second controller, wherein the first controller and the second controller are of different models. Detailed descriptions refer to the corresponding descriptions of the above method embodiments, which will not be repeated here.

[0040] S22 , controlling the first controller and the second controller to interact with each other via control signals based on the touch screen macro instruction.

[0041] Specifically, the above step S22 may include:

[0042] S221 , in response to a data storage space construction operation, generating a first data storage space for the first controller and a second data storage space for the second controller based on the construction operation.

[0043] The first data storage space is used to store data sent from the first controller to the second controller; the second transmission data storage space is used to store data sent from the second controller to the first controller. A technician can create data storage spaces using the program compilation interface of the touch screen. Accordingly, the touch screen of the welding test equipment can respond to the technician's operation to create data storage spaces, generating a first data storage space for the first controller and a second data storage space for the second controller.

[0044] For example, the first controller is NX1P2 PLC and the second controller is CP1H PLC. The technician can construct a W array for NX1P2 PLC and a Q array for CP1H PLC, and use the W array as the first data storage space and the Q array as the second data storage space.

[0045] S222: Transmit the data in the second data storage space to the first controller based on the touch screen macro instruction.

[0046] The data in the second data storage space is extracted through the touch screen macro instruction, and the data is transmitted to the first controller, thereby enabling the control signal generated by the second controller to be transmitted to the first controller.

[0047] Specifically, the above step S222 may include:

[0048] (1) Obtain second data corresponding to the second controller.

[0049] (2) The second data is transferred to the second data storage space.

[0050] (3) In response to a compiling operation on the touch screen macro instruction, a first instruction for the first data storage space is determined based on the compiling operation.

[0051] (4) Transmitting the data in the first data storage space to the first controller based on the first instruction.

[0052] The second data is data sent by the second controller to the first controller. The second data is used to represent the motion state of the second controller, including motion position, motion direction, etc. The second data can be stored in registers of the second controller. For example, registers D10-D15 are used to store the second data, and register D10 is used as the data starting address of the signal sent by the second controller CP1H PLC to the first controller NX1P2 PLC.

[0053] Specifically, the second data is transmitted to the Q array, and the data in the Q array is transmitted to the array variable CP_IN_NX established by the first controller, and the signal or information received by the first controller and sent by the second controller is stored through the array variable.

[0054] S223: Transmit the data in the first data storage space to the second controller based on the touch screen macro instruction.

[0055] The data in the first data storage space is extracted through the touch screen macro instruction, and the data is transmitted to the second controller, thereby enabling the control signal generated by the first controller to be transmitted to the second controller.

[0056] Specifically, the above step S223 may include:

[0057] (1) Obtain first data corresponding to the second controller.

[0058] (2) The first data is transferred to the second data storage space.

[0059] (3) In response to a compiling operation on the touch screen macro instruction, a second instruction for the first data storage space is determined based on the compiling operation.

[0060] (4) Transmitting the data in the second data storage space to the second controller based on the second instruction.

[0061] The first data is data sent from the first controller to the second controller. The first data is used to represent the motion state of the first controller, including motion position, motion direction, etc. The first data can be stored in an array variable of the first controller. For example, the array variable NX_OUT_CP of the first controller is constructed and the second data is stored in this data variable.

[0062] Specifically, the data in the array variable NX_OUT_CP established by the first controller is transferred to the W array, and then the data pairs in the W array are transmitted to the registers of the second controller. For example, the data in the W array are stored in registers D20-D25, and register D20 is used as the data starting address for the second controller CP1H PLC to receive the signal sent by the first controller NX1P2 PLC.

[0063] Data interaction between the first controller and the second controller is realized by compiling touch screen macro instructions, which simplifies the interaction process, making the data communication between the first controller and the second controller more stable and the interaction more flexible.

[0064] S23: Determine the control states of the first controller and the second controller according to the interaction result of the control signal.

[0065] Specifically, the above step S23 may include:

[0066] S231 : Determine a first servo control state of the first controller and a second servo control state of the second controller based on an interaction result of the control signal.

[0067] The first servo control state indicates the motion state of the servo module controlled by the first controller, specifically including motion direction, motion distance, motion position, etc. For example, the first controller can control the servo module of the welding test equipment to move forward and backward and up and down.

[0068] The second servo control state represents the motion state of the servo module controlled by the second controller, specifically including motion direction, motion distance, motion position, etc. For example, the second controller can control the servo module of the welding test equipment to move left and right.

[0069] S232 , determining a welding control state based on the first servo control state and the second servo control state.

[0070] The welding control state identifies the spatial motion state of the servo module. The first and second servo control states coordinate with each other to control the movement of the servo module's multiple axes to the component's welding position for precise welding operations. For example, for the precise positioning of a four-way valve, the second controller, CP1H PLC, primarily controls the servo module's left and right motion, while the first controller, NX1P2 PLC, controls the servo module's forward, backward, and up and down motion. Because welding requires back-and-forth motion control of the left and right axes, coordination with the remaining six axes is essential. Through the coordination of the CP1H PLC and NX1P2 PLC, the spatial orientation of the servo module is controlled to achieve precise positioning of the four-way valve.

[0071] The signal communication method for welding testing equipment provided in this embodiment facilitates data transmission via touchscreen macros by establishing a first data storage space for the first controller and a second data storage space for the second controller. This reduces the need for controller-specific logic code and facilitates human-computer interaction. The interaction between the first and second controllers determines their respective servo control states, enabling welding control through the coordination of the first and second controllers, thereby improving the automation of welding control.
