[0026] The specific embodiments of this application will be further described below with reference to the accompanying drawings.

[0027] It is readily understood that, based on the technical solution of this application, various structural and implementation methods can be interchanged by those skilled in the art without altering the essential spirit of this application. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this application and should not be considered as the entirety of this application or as limitations or restrictions on the technical solution of the application.

[0028] This embodiment provides an integrated device for electrical wiring of wind turbine generators, including an integrated backplane, which is divided into multiple terminal block areas, such as... Figure 1 As shown, the multiple terminal block areas include:

[0029] The first terminal block area 11 is where the wiring terminals of the PLC controller are set;

[0030] The second terminal block area 12 is equipped with IO wiring terminals;

[0031] The third terminal block area 13 is equipped with analog signal terminals and power supply terminals;

[0032] The fourth terminal block area is equipped with communication wiring terminals.

[0033] The fourth terminal block area in the figure includes two parts: the first communication terminal area 41 and the second communication terminal area 42. Different communication terminal areas can be used to connect different types of communication module connection lines.

[0034] The solution provided in this embodiment divides an integrated backplane into multiple terminal block areas. These terminal block areas include a first terminal block area 11 for PLC controller wiring terminals, a second terminal block area 12 for I / O wiring terminals, a third terminal block area 13 for analog and power wiring terminals, and a fourth terminal block area for communication wiring terminals. This device features a compact design, saving space and making it suitable for installation in control cabinets or field equipment. Wiring can be completed simply by connecting each terminal block area directly to predefined wiring templates and quick connectors, reducing on-site wiring time and improving installation efficiency.

[0035] Preferably, such as Figure 1 As shown, the integrated device for electrical wiring of wind turbine generators includes the following in the first terminal block area 11: a USB interface, primarily used for connecting to computer equipment for program downloading, uploading, module configuration, and debugging, facilitating PLC programming and maintenance; at least one serial communication interface (using two serial communication interfaces COM1 and COM2 in the figure as an example), typically an RS-232 or RS-485 standard serial communication interface, used for communication with other serial devices (such as touch screens, other PLCs, smart meters, etc.) to achieve data interaction and transmission; and at least one Ethernet interface (using two Ethernet interfaces ETH1 and ETH2 in the figure as an example), supporting Ethernet communication protocols (such as TCP / IP), used for communication with... Devices in the Ethernet network (such as computers, switches, and other Ethernet PLCs) perform high-speed data communication; and indicator lights are used to display the working status of the PLC controller. The indicator lights in the diagram for displaying the PLC controller's working status include: RUN: Run indicator light, illuminated when the module is running normally, indicating that the program is in running state; INIT: Initialization indicator light, illuminated when the module performs initialization operations (such as startup, reset, and subsequent initialization); ERR: Error indicator light, illuminated when the module malfunctions (such as program errors, hardware failures, communication anomalies, etc.), indicating the existence of an error; L: Status auxiliary indicator light, with corresponding status indication meanings in different scenarios; Mode switch indicator light H, including the following three modes: TEST: Test mode, used to test some functions or hardware without actually running the complete program; PROG: Programming mode, in which the program within the module can be written, modified, downloaded, etc.; RUN: Run mode, in which the module executes the downloaded control program to achieve automated control functions. The interfaces and indicator lights in the first terminal board area 11 facilitate user operation and monitoring of the PLC controller, improving the system's operability and visualization.

[0036] Preferably, in the integrated device for electrical wiring of wind turbine generators described above, the second terminal block area 12 includes multiple regions, with different second terminal block areas 12 spaced apart. Figure 2 Taking the structure shown as an example, the second terminal board area 12 includes two parts, and the third terminal board area 13 is disposed between the two second terminal board areas. The different second terminal board areas 12 are spaced apart from each other, making the wiring layout more reasonable and easier to identify and operate.

[0037] Furthermore, status lights are provided in the second terminal block area 12, the number of which is the same as the number of terminals in the IO terminal blocks. Each status light indicates the connection status of the corresponding terminal. This design allows operators to intuitively understand the working status of each IO terminal block, facilitating timely fault detection and troubleshooting. Specifically, multiple IO terminal blocks are provided in the second terminal block area (three IO terminal blocks are shown as an example in the figure), with twelve IO terminals on each terminal block. This standardized design facilitates wiring and management.

[0038] like Figure 1 and Figure 2 As shown, the third terminal block area 13 is provided with multiple analog terminal blocks (three analog terminal blocks are shown as an example in the figure). Each analog terminal block has eight analog terminal groups, and each analog terminal group includes one analog input terminal and one analog output terminal. This makes the input and output of analog signals clearly correspond, reducing the possibility of wiring errors. Furthermore, the power supply terminals in the third terminal block area include 24V DC power supply terminals and 12V DC power supply terminals, thus meeting the power supply needs of different devices.

[0039] like Figure 1 and Figure 2 As shown, the fourth terminal board area includes a first communication terminal area 41 and a second communication terminal area 42. The first communication terminal area 41 is a fiber optic network interface setting area, and the second communication terminal area 42 is a CAN bus interface setting area. Both the fiber optic network interface setting area and the CAN bus interface setting area are equipped with interface status indicator lights. These indicator lights allow operators to monitor the working status of the communication interface in real time, ensuring the stability and reliability of communication. As needed, the fourth terminal board area can also be expanded to include other communication interface terminal areas.

[0040] like Figure 2As shown, the integrated backplane also includes a main power terminal block area 15, which includes 24V DC power terminals and power status indicator lights. This solution makes power management more centralized and intuitive, facilitating the monitoring of the power status of the entire system.

[0041] The integrated device for electrical wiring of wind turbine generators provided in the above embodiments of this application achieves modular and integrated management of electrical wiring by rationally dividing terminal board areas with different functions and setting corresponding wiring terminals and status indicator lights in each area. This design not only simplifies the electrical wiring process of wind turbine generators and reduces the possibility of wiring errors, but also facilitates later maintenance and troubleshooting, improving the operating efficiency and reliability of wind turbine generators.

[0042] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0043] The above are merely the principles and preferred embodiments of this application. It should be noted that, for those skilled in the art, several other modifications can be made based on the principles of this application, and these modifications should also be considered within the scope of protection of this application.
