Description

Technical Field

[0001] The invention belongs to the technical field of terminal equipment debugging, and in particular relates to a remote debugging system for fan ring network terminal equipment. Background Art

[0002] With the country's vigorous development of new energy, various new energy application scenarios have emerged in large numbers. Among them, wind power, as a major member of new energy, is the focus of national development. Various high-power wind farms are gradually being built and put into use. Wind farms are generally located in relatively remote areas, occupy a large area, and have a harsh environment. Wind turbines, as the most important terminal equipment, are distributed in various locations of wind farms.

[0003] as follows Figure 1 Figure 1 shows a typical network architecture of a wind farm. Due to the above characteristics of wind farms, the ring network becomes the best choice for the topology architecture within the farm. The HSR ring network protocol is also applied to this scenario because of its high reliability and seamless redundancy. In order to monitor the operating status of wind turbines in real time, each wind turbine will deploy a terminal device based on the HSR ring network, which monitors the status of the wind turbine in real time. Several terminal devices form several independent ring service networks. Each ring network is connected to the main control room through the HSR switch. The operation and maintenance personnel can monitor the operating status of each group of wind turbines in real time in the main control room. When the terminal equipment needs to be debugged and maintained, if the ring network terminal equipment is debugged remotely through the ring business network, it will be affected by the business data sent by the ring network terminal equipment during debugging, resulting in unstable debugging services. Therefore, debugging personnel and operation and maintenance personnel are usually required to go to the terminal equipment, connect the terminal equipment on-site through a PC or directly operate the terminal equipment panel to perform debugging work. Since the distance between the main control room and each wind turbine is relatively far, the transportation is inconvenient, and the terminal equipment is generally deployed on the wind turbine, with a vertical distance of about tens of meters from the ground, the debugging work is difficult and dangerous, consumes a lot of manpower and material resources, and is inefficient. Summary of the invention

[0004] The purpose of the present invention is to provide a remote debugging system for wind turbine ring network terminal equipment to solve the technical problems in the prior art that the debugging of wind turbine terminal equipment is difficult, dangerous, consumes a lot of manpower and material resources, and is inefficient.

[0005] To solve the above technical problems, the present invention provides a remote debugging system for a wind turbine ring network terminal device, comprising a debugging client, several debugging servers and several HSR virtual network cards for debugging services, different HSR virtual network cards are respectively mounted on different ring network terminal devices and share physical channels with the business modules of the corresponding ring network terminal devices, different debugging servers are used to connect to different ring network terminal devices, the debugging client is used to send debugging instructions to the debugging server through the physical channel and the HSR virtual network card and receive data sent by the debugging server, the debugging server is used to exchange data with the business module of the corresponding ring network terminal device according to the received debugging instructions, so as to debug the corresponding ring network terminal device; wherein, the business module is used to monitor the operating status of the wind turbine.

[0006] The beneficial effects are as follows: the remote debugging system for wind turbine ring network terminal equipment of the present invention forms a ring debugging network without setting up a new network interface and ring network switch by mounting an HSR virtual network card for debugging services on the ring network terminal equipment, making the remote debugging service more efficient, and by setting up a virtual network card, the debugging network is completely decoupled from the complex and changeable business network topology architecture, and is fully adaptive to various application scenarios based on the ring network, thereby achieving data independence between business services and debugging services, ensuring that the debugging service is not affected by specific business services, and improving the stability of the debugging service. In addition, by adopting the remote debugging system for wind turbine ring network terminal equipment of the present invention, debugging can be done in the main control room through the debugging client on the PC to accurately debug each terminal device, achieving the goal of debugging personnel completing terminal equipment debugging and maintenance work without leaving the room, improving the work efficiency of debugging personnel and users, making debugging and operation and maintenance work simpler and safer, and saving a lot of manpower, material and financial resources.

[0007] Preferably, the uploaded data includes at least one of the operating status, alarm status, voltage sampling value and current sampling value of the ring network terminal device.

[0008] Preferably, during the debugging process, the debugging server is used to modify at least one operating parameter of the ring network terminal device including an operating protection constant, a sampling coefficient and an IP address.

[0009] Preferably, during the debugging process, the debugging server is used to control the action of the fan outlet relay and / or the start and stop of the fan.

[0010] Preferably, during the debugging process, the debugging server is used to upload and download at least one of the software, device log, action report and recording file of the ring network terminal device.

[0011] Preferably, the debugging server is configured with an IP whitelist authentication mechanism, and the IP whitelist authentication mechanism is used to allow only devices corresponding to IP addresses in the IP whitelist to access the debugging server.

[0012] The beneficial effect is that by setting up an IP whitelist authentication mechanism, only the IP address of the debugging client can be set to the whitelist, thereby preventing other devices except the debugging client from accessing data to the debugging server, thereby improving the security of the remote debugging system for wind turbine ring network terminal equipment.

[0013] Preferably, the debugging server is also used to initialize the HSR virtual network card and automatically generate a virtual network card IP address.

[0014] Preferably, when generating parameters related to the virtual network card IP address, the ID of the ring network terminal device mounted on the HSR virtual network card is used as the host ID in the IP address, and the ring network ID where the ring network terminal device mounted on the HSR virtual network card is located is used as the subnet ID in the IP address.

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0020] Implementation example of a remote debugging system for wind turbine ring network terminal equipment:

[0021] like Figure 1 As shown in the figure, the wind turbine monitoring system includes a monitoring host, multiple groups of wind turbines and a ring network switch. Each wind turbine is connected to a terminal device. The terminal devices connected to each group of wind turbines form a ring network. Each ring network is connected to the monitoring host in the main control room through a ring network switch and a hub. The terminal devices are used to monitor and control the status of the wind turbines in real time, and the monitoring host is used to receive and display the status information of the wind turbines sent by all terminal devices. Figure 2As shown, the remote debugging system for wind turbine ring network terminal equipment of the present invention includes a debugging client, several debugging servers and several network cards, and different network cards are mounted on different ring network terminal equipment respectively, so as to form a ring debugging network. The network card adopts an HSR virtual network card. Since the debugging network and the business network share the same physical channel, the coupling between the two is reduced by adopting a virtual network card; the debugging server communicates with the debugging client through the HSR virtual network card and the physical channel on the ring network terminal equipment. The debugging server is used to exchange data with the business module of the corresponding ring network terminal equipment; the business module is used to monitor the operating status of the wind turbine; the debugging client is used to send debugging instructions to the debugging server and receive data sent by the debugging server. The debugging server is connected to the ring network virtual network card of the corresponding ring network terminal equipment and is used to exchange data with the corresponding business module according to the debugging instructions sent by the debugging client, so as to debug the corresponding ring network terminal equipment. The virtual network card is only used for debugging services, and is isolated from the receiving data node and the business layer, thereby ensuring the stability of the debugging service module.

[0022] like Figure 3 and Figure 4 As shown, the debugging server is also used to initialize the HSR virtual network card and automatically generate the relevant parameters of the virtual network card IP address, thereby forming a ring debugging network. When generating the relevant parameters of the virtual network card IP address, the ID of the ring network terminal device mounted by the HSR virtual network card, namely DEVID, is used as the host ID in the IP address, and the ring network ID of the ring network terminal device mounted by the HSR virtual network card, namely HSRID, is used as the subnet ID in the IP address; the IP address related parameters are initialized as: IP = 192.88.HSRID.DEVID, MASK = 255.255.0.0. After the HSR virtual initialization of all ring network terminal devices in the ring network m is completed, the ring debugging network is automatically constructed successfully. At this time, the debugging server can access the debugging server corresponding to any terminal device in the ring through the communication interface of the HSR switch and the IP address of each virtual network card. When the debugging personnel implement the debugging, by checking the network topology diagram of the ring network terminal device, confirming the ring network number ID: m and the device number ID: n where the object to be debugged is located, the debugging IP address (192.88.mn) of the debugging object can be confirmed.

[0023] The debugging client and the debugging server exchange data through TCP service. In order to improve the security of the debugging network, the server provides an IP whitelist authentication mechanism, that is, the source IP address of the client requesting access must be secure, otherwise the server will reject the client's connection request.

[0024] The debugging client is a visual graphical tool running on a PC. Various remote debugging functions are displayed in a graphical manner, which improves the friendliness of human-computer interaction. The debugging client and debugging server provide functions such as remote virtual LCD, remote configuration, remote control, and remote file services. For example, through the remote virtual LCD service, the status of the indicator lights such as the operation and alarm of the ring network terminal equipment can be monitored, and the sampling values ​​of the voltage, current, and non-electrical quantities of the terminal equipment can be read; through the remote configuration service, the terminal equipment operation protection constant, sampling coefficient, IP address and other operating parameters can be modified; through the remote control service, the fan outlet relay action, fan start and stop and other operations can be controlled; through the remote file service, the software, equipment log, action report, recording and other file upload and download functions can be realized.

[0025] The remote debugging system for wind turbine ring network terminal equipment of the present invention provides a safe, stable and efficient remote debugging means for the equipment in the ring network; the HSR ring network virtual network card technology realizes the data independence between the business service and the debugging service, ensures that the debugging service is not affected by the specific business, and improves the stability of the service; the automatic construction of the ring debugging network technology makes the remote debugging service more efficient, and the debugging network is completely decoupled from the complex and changeable application network topology architecture, and is fully adaptive to various application scenarios based on the ring network. The debugging server and the client cooperate with each other, and provide rich debugging means such as remote virtual LCD, remote configuration, remote control, and remote file service through a specific private protocol, so that the user only needs to be in the main control room, through the debugging client on the PC to accurately control and monitor each terminal device. The invention realizes the goal that the debugging personnel can complete the debugging and maintenance of the terminal equipment without leaving the room, improves the work efficiency of the debugging personnel and users, makes the debugging and operation and maintenance work simpler and safer, and saves a lot of manpower, material resources and financial resources.
