[0002] In recent years, with the continuous deepening of unmanned operation in hydropower plants, most hydropower plants have entered the unmanned operation mode, and the number of on-site operation personnel in hydropower plants has decreased year by year. In the unmanned operation mode, on the one hand, the main equipment of the hydropower plant is required to be reliable and stable, and on the other hand, it is necessary to use intelligent technology to assist remote monitoring. The traditional industrial TV system can only view the position that needs to be monitored by manually calling the camera and adjusting the camera position. Due to peak regulation, frequency regulation, and water-photovoltaic complementary load adjustment, the number of automatic start and stop times of the hydropower plant is as high as more than 10 times a day. During the automatic start and stop process, the industrial TV system screen needs to be called to align with the important positions of the automatic start and stop units, such as the unit water machine room, the unit slip ring room, the unit outlet circuit breaker, etc. The traditional industrial TV system needs to call multiple pictures for different units, and the calling process is time-consuming and laborious.

[0007] A fourth object of the present application is to provide a computer program product.

[0008] To achieve the above-mentioned purpose, the first embodiment of the present application proposes a linkage method for automatically starting and stopping the industrial television system to retrieve the screen, including:

[0009] When the unit is automatically started or stopped, the hydropower computer monitoring system LCU sends a signal during the automatic start-up or automatic stop process;

[0010] The signal is sent to the main server of the computer monitoring system, and the main server of the computer monitoring system pushes the signal to the data push server of zone II through the horizontal firewall of zone I / II;

[0011] The zone II data push server pushes the signal to the zone III data receiving server via the zone II / III lateral isolation device;

[0012] The zone III data receiving server converts the data communication protocol of the signal into a MODBUS TCP communication protocol, and sends the converted signal to the industrial television system linkage server;

[0013] The industrial television system linkage server acquires the image information according to the converted signal and sends it to the industrial television system server;

[0014] Based on the retrieved picture information, the industrial television system server adjusts the camera position through a preset position to obtain the retrieved picture, and presents the retrieved picture on the large screen of the industrial television system.

[0015] Optionally, also include:

[0016] When the signal disappears during the automatic startup process or the automatic shutdown process, the picture retrieved on the large screen of the industrial television system is automatically exited and restored to the original retrieved picture of the industrial television system.

[0025] To achieve the above-mentioned purpose, the fourth aspect of the present application provides a computer program product, which implements any method in the first aspect when executed by a processor.

[0026] The linkage method, device, electronic device and storage medium for automatically starting and stopping and retrieving the screen of the industrial television system provided in the present application connect the data link between the computer monitoring system of the hydropower plant with water and photovoltaic complementary power in safety zone I of the electric power monitoring system and the industrial television system in safety zone III of the electric power monitoring system, and transmit the automatic start-up and automatic shutdown signals of the hydropower units to the industrial television system on the premise of meeting the network security of the electric power monitoring system. When the industrial television system receives the automatic start-up and automatic shutdown signals, it retrieves the screen of the industrial television system server, adjusts the camera position through preset positions, and presents the screen on the large screen of the industrial television system for remote operation on-duty personnel to monitor.

[0028] The above and / or additional aspects and advantages of the present application will become apparent and easily understood from the following description of the embodiments in conjunction with the accompanying drawings, in which:

[0029] Figure 1 A flowchart of a linkage method for automatically starting and stopping and retrieving images of an industrial television system provided in an embodiment of the present application. DETAILED DESCRIPTION

[0030] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0031] In recent years, with the continuous deepening of unmanned operation in hydropower plants, most hydropower plants have entered the unmanned operation mode, and the number of on-site operation personnel in hydropower plants has decreased year by year. In the unmanned operation mode, on the one hand, the main equipment of the hydropower plant is required to be reliable and stable, and on the other hand, it is necessary to use intelligent technology to assist remote monitoring. The traditional industrial TV system can only view the position that needs to be monitored by manually calling the camera and adjusting the camera position. Due to peak regulation, frequency regulation, and water-photovoltaic complementary load adjustment, the number of automatic start and stop times of the hydropower plant is as high as more than 10 times a day. During the automatic start and stop process, the industrial TV system screen needs to be called to align with the important positions of the automatic start and stop units, such as the unit water machine room, the unit slip ring room, the unit outlet circuit breaker, etc. The traditional industrial TV system needs to call multiple pictures for different units, and the calling process is time-consuming and laborious.

[0032] To address this problem, the present application provides a linkage method for automatically starting and stopping the system to retrieve images of an industrial television system. Figure 1 The present invention provides a flowchart of a linkage method for automatically starting and stopping the industrial television system to retrieve the screen. Figure 1 As shown, the method comprises the following steps:

[0033] Step 101, when the unit is automatically started or automatically stopped, the hydropower computer monitoring system LCU sends a signal of the automatic start-up process or the automatic stop process.

[0034] In the embodiment of the present application, the hydropower computer monitoring system LCU (Local Control Unit) is a control unit directly connected to the hydropower unit, responsible for monitoring the operating status of the unit, such as temperature, pressure, flow, etc.

[0035] When the unit is automatically started or stopped, the LCULCU will generate a signal containing the unit status information, which can be in binary code, digital or text format. This signal represents the state change of the unit, which may be a status flag, operation instruction or fault alarm.

[0036] Step 102, the signal is sent to the main server of the computer monitoring system, and the main server of the computer monitoring system pushes the signal to the data push server of zone II through the zone I / II horizontal firewall.

[0037] In an embodiment of the present application, the signal is transmitted to the main server via a wired or wireless data link. During the transmission process, the signal may be checked and encrypted to ensure the integrity and security of the data.

[0038] In addition, the lateral firewall in Zone I / II will check the legitimacy of the signal to prevent malware or unauthorized access. Moreover, the firewall may filter out unnecessary data packets and only allow signals that comply with security policies to pass through.

[0039] Step 103: The zone II data push server pushes the signal to the zone III data receiving server through the zone II / III lateral isolation device.

[0040] In the embodiment of the present application, the II / III zone horizontal isolation device further ensures the security of data, and it may adopt physical isolation or logical isolation technology.

[0041] It can be understood that both the zone I / II horizontal firewall and the zone II / III horizontal isolation device have data filtering and security protection functions.

[0042] Further, the signal is pushed to the Zone III data receiving server, which usually involves the conversion and optimization of the network protocol.

[0043] Step 104, the zone III data receiving server converts the data communication protocol of the signal into the MODBUS TCP communication protocol, and sends the converted signal to the industrial television system linkage server.

[0044] In a possible embodiment, the zone III data receiving server is MODBUS data transmission software, which is software for implementing MODBUS protocol communication, and allows information to be exchanged between different devices and systems.

[0045] It can be understood that MODBUS is a widely used serial communication protocol, mainly used in industrial environments, such as supervisory control and data acquisition systems (SCADA), distributed control systems (DCS), etc., and this application does not make specific limitations on this.

[0046] In the embodiment of the present application, the zone III data receiving server converts the signal from the original communication protocol to the MODBUS TCP protocol. MODBUS is a communication protocol suitable for industrial environments. The conversion may include data format adjustment, rate adaptation, error detection and correction, etc., which should be determined according to the actual scenario.

[0047] Step 105: the industrial television system linkage server obtains the image information according to the converted signal and sends it to the industrial television system server.

[0048] In the embodiment of the present application, the industrial television system linkage server is responsible for parsing the signal and determining the image to be retrieved based on the signal content. The server may parse specific fields in the signal, such as the camera number, preset position number, etc.

[0049] Furthermore, the linkage server determines the image information to be retrieved based on the parsed signal, which may include the position of the camera, parameters of the preset position, resolution of the retrieved image, etc.

[0050] In addition, the process in which the linkage server transmits the retrieved picture information to the industrial television system server is usually carried out through TCP / IP or other industrial communication protocols, and this application does not make specific limitations on this.

[0051] Step 106, based on the retrieved picture information, the industrial television system server adjusts the camera position through the preset position to obtain the retrieved picture, and presents the retrieved picture on the large screen of the industrial television system.

[0052] In a possible embodiment, the industrial television system server is industrial television management software, which is an application specially designed for monitoring and managing industrial television systems. This application does not specifically describe or limit the software code. At present, the industrial television system has the function of realizing video screen linkage through the industrial television system software. Sending the relevant operating data of the hydropower unit to the industrial television system can realize the function of automatically starting and stopping and retrieving the screen of the industrial television system.

[0053] In the embodiment of the present application, the industrial television system server controls the camera to move to a specified position according to the preset position parameters in the retrieved picture information. Specifically, the server sends a control command to the camera, such as a PTZ (Pan-Tilt-Zoom, i.e., horizontal rotation, tilt, and zoom) command, and the camera adjusts its position according to the server's instructions to capture the required picture.

[0054] Furthermore, the server may compress, enhance, and process the images to meet network transmission and display requirements, and then display the processed images on a large screen of the industrial TV system for operators to monitor.

[0055] In addition, in some embodiments of the present application, when the signal disappears during the automatic startup process or the automatic shutdown process, the picture called up on the large screen of the industrial television system is automatically exited and restored to the original called up picture of the industrial television system.

[0056] It can be understood that the entire process above is automated, reducing human intervention, improving response speed and accuracy of operations. At the same time, through multi-layer security measures, data security and system stability are ensured.
