Description

Technical Field

[0001] The invention belongs to the technical field of video monitoring, and in particular relates to a method for processing an isolating switch video detection fault and a related device. Background Art

[0002] Gas Insulated Metal Enclosed Switchgear (GIS) is one of the important components of the power system. It is an important device for protecting the safe operation of the power system and controlling the circuit of the power system. Therefore, the operating status of GIS is related to the safety of the entire power system. The structure of GIS equipment is complex. Due to unforeseen mechanical or electrical failures during long-term operation, the switch contact indication status often does not match the actual contact status, or the contact is not fully opened. Since the contacts are enclosed inside the GIS, the actual position of the contacts cannot be directly grasped, which poses a hidden danger to the safe operation of the GIS equipment. In order to directly monitor the switch status and avoid GIS operation accidents, video monitoring is gradually being used in actual projects as a direct and effective means.

[0003] After searching, the patent document with publication number CN104320614A discloses a GIS equipment internal video monitoring system and method, which digs a hole at the static contact of the isolating switch to install an observation window, observes the contact status of the isolating switch through a video sensor, isolates the power line of the video sensor only through a switch, and turns on the power when it needs to be started. Regardless of the position of the isolating switch, the video sensor is started, and the life of the video sensor is short.

[0004] In addition, when the GIS disconnector is in the process of opening or closing, the live side disconnector moves too slowly when cutting the GIS short pipe. Each operation of the disconnector in the GIS will cause dozens or even hundreds of re-ignitions. The voltage at both ends of the contact gap suddenly drops within a few nanoseconds, and the voltage steep wave continuously generates traveling waves in the GIS, resulting in complex refraction, reflection and superposition, and generating very fast transient overvoltage (VFTO). At this time, starting the video sensor will damage the video sensor, and it is even possible to import the VFTO into the video server equipment or even the power system through the video sensor transmission line, causing damage to the background system. Summary of the invention

[0005] The purpose of the present invention is to provide a method and a related device for processing video detection faults of an isolating switch, which solves the problem that VFTO may damage a video sensor or a background system when a video detection fault occurs in the prior art.

[0006] The present invention is achieved through the following technical solutions: A method for handling a disconnect switch video detection fault, comprising the following steps: S1. Get the auxiliary contact node status of the disconnector; Based on the state of the auxiliary contact node, it is judged whether the isolating switch is in the process of opening and closing. If so, the video sensor is controlled to be in a disconnected state; the disconnected state is to disconnect all the power lines and signal lines of the video sensor; If not, start S2; S2. Obtain the time of the disconnector opening and closing operation, and determine whether the current time of the disconnector is greater than the preset time from the last opening and closing operation; If not, the video sensor is kept in the disconnected state; if so, the video sensor is controlled to be in the connected state, and S3 is started; the connected state is to connect all the power lines and signal lines of the video sensor; S3, obtaining the temperature of the video sensor, and determining whether the temperature of the video sensor exceeds a preset temperature; If not, the video sensor acquires video information; If yes, the video sensor is turned off, and when the temperature drops below a preset temperature, the video sensor is turned on to obtain video information of the video sensor; S4, processing the video information, identifying the contact position state of the disconnector according to the processed video information, and comparing it with the auxiliary contact node state; If the two pieces of information are consistent, the fault judgment ends; If the information of the two is inconsistent, an error alarm will be issued.

[0007] Further, in S4, if the two pieces of information are consistent, the fault judgment is completed, the power line and signal line of the video sensor are disconnected, and the next startup is waited; Or after an error alarm, disconnect the power cord and signal cable of the video sensor and wait for the next startup.

[0008] Furthermore, there are three modes for the next automatic start, specifically: The first type is timed start: wait until the last video monitoring is finished, and then start the video monitoring process again after the first time; The second method is to obtain the auxiliary contact node status of the disconnector in real time. When the disconnector is detected to have an opening and closing operation, the video monitoring process is started again after a second period of time. The third method is that the operation and maintenance personnel manually start the video monitoring process.

[0009] The present invention also discloses an isolating switch video detection fault processing system of the isolating switch video detection fault processing method, comprising: A data acquisition module, used to obtain the auxiliary contact node status of the disconnector; The opening and closing state judgment module is used to judge whether the disconnector is in the opening and closing process based on the state of the auxiliary contact node. If so, the video sensor is controlled to be in the disconnected state; If not, start the time judgment module; The time judgment module is used to obtain the time of the disconnecting and closing operation of the isolating switch, and judge whether the time between the current time of the isolating switch and the last disconnecting and closing operation exceeds the preset time; if not, the video sensor is kept in the disconnected state; if so, the video sensor is controlled to be connected and the temperature comparison module is started; A temperature comparison module is used to obtain the temperature of the video sensor and determine whether the temperature of the video sensor exceeds a preset temperature; If not, the video sensor acquires video information; If yes, the video sensor is turned off, and when the temperature drops below a preset temperature, the video sensor is turned on to obtain video information of the video sensor; An identification and judgment module is used to process the video information, identify the contact position state of the disconnector according to the processed video information, and compare it with the auxiliary contact node state; If the two pieces of information are consistent, the fault judgment ends; If the information of the two is inconsistent, an error alarm will be issued.

[0010] The present invention also discloses a video detection fault processing device for an isolating switch, comprising a video sensor, a temperature sensor, a GIS control cabinet, a controllable switch, a video server, a processor and a power supply; The temperature sensor is used to monitor the temperature of the video sensor. Both the video sensor and the temperature sensor are connected to the processor; the processor is connected to the power supply; The GIS control cabinet is used to collect the auxiliary contact node status of the disconnector. The GIS control cabinet is connected to the processor; The controllable switch is arranged on the line connecting the video sensor and the video server, and on the line connecting the video sensor and the power supply; The processor includes the isolating switch video detection fault processing system, which is used to control the on / off state of the controllable switch and the start or disconnection of the video sensor through the collected video, temperature and auxiliary contact node status information; and to identify the contact position state of the isolating switch and make comparative judgments.

[0011] Furthermore, the video sensor and the temperature sensor are integrated in the metal shell, a light source and a power module are installed in the inner cavity of the metal shell, and an observation window is prefabricated on one side of the metal shell; The power module is respectively connected with the temperature sensor, the video sensor and the light source through the protection circuit. Furthermore, a partition is installed in the metal housing, and the video sensor and the light source are respectively fixed on both sides of the partition; The observation window is made of transparent plexiglass.

[0012] The present invention also discloses a computer device, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the isolating switch video detection fault processing method is implemented when the processor executes the computer program.

[0013] The present invention also discloses a computer-readable storage medium, wherein the computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, the isolating switch video detection fault processing method is implemented.

[0014] The present invention also discloses a computer program product, comprising a computer program / instruction, which implements the isolating switch video detection fault processing method when executed by a processor.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: The present invention discloses a method for handling faults in video detection of an isolating switch. Based on the auxiliary contact node state of the isolating switch, it is first determined whether the isolating switch is in the process of opening and closing. If it is in the process of opening and closing, in order to avoid the conduction interference of VFTO, the video sensor is in the disconnected state; if it is not in the process of opening and closing, it is necessary to further determine how long the last opening and closing operation of the isolating switch has been completed, which is also for the conduction interference of VFTO, because in a very short time after the isolating switch has been actuated, the overvoltage still exists, which will also interfere with the video sensor. The video sensor can only be started when the time for the isolating switch to meet the distance from the most recent operation exceeds the preset time. After starting, in order to avoid the video sensor temperature being too high, the present invention collects the temperature of the video sensor in real time. When the temperature is high, the video sensor still needs to be turned off to prevent the high temperature from affecting the working life of the video sensor; when the temperature is appropriate, the video sensor records the video information, and finally after processing, identifies the contact position state of the isolating switch, and then compares it with the auxiliary contact node state obtained at the beginning. When the information of the two is inconsistent, an error alarm is issued. Through the monitoring method of the present invention, the video sensor is started only when the GIS is running stably and safely, thereby avoiding the interference of VFTO on the background equipment and prolonging the service life of the video sensor.

[0016] The present invention also discloses a device for handling video detection faults of an isolating switch, including a video sensor, a temperature sensor, a GIS control cabinet, a controllable switch, a video server, a processor and a power supply. The temperature sensor is used to monitor the working temperature of the video sensor in real time. If the temperature exceeds the threshold, the video sensor is turned off in time to prevent the working life of the video sensor from being affected by excessive temperature; a controllable switch is set on the line connecting the video sensor and the video server, and on the line connecting the video sensor and the power supply, and the VFTO interference is isolated by disconnecting the controllable switch; the current position of the isolating switch is judged by the auxiliary contact of the isolating switch in the GIS control cabinet, so as to ensure that the video sensor cannot be started during the operation of the isolating switch and within a preset time after the operation, thereby isolating the VFTO interference.

[0017] Furthermore, the video sensor is fixed in the metal casing, and the video sensor is close to the observation window, so that the position of the video sensor and the light source is fixed. In engineering applications, the fixed position is useful for adjusting the focal length of the video sensor. The contact positions in different sensor images can be standardized with small differences. The sensor and light source positions are debugged before leaving the factory, and there will be no large displacement during transportation. Only simple adjustments are required on site, reducing the workload of on-site debugging.

[0018] Furthermore, after the last monitoring process is completed, three specific startup methods are designed for the next time. All three startup methods will trigger the monitoring process. Each startup method must be cycled according to the monitoring process. Different startup methods are designed mainly to meet different customer needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the purpose, technical solution and advantages of the present invention more clear, the following is further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention, that is, the embodiments described are only part of the embodiments of the present invention, not all embodiments.

[0022] The components described and shown in the drawings and embodiments of the present invention may be arranged and designed in various configurations. Therefore, the detailed description of the embodiments of the present invention provided in the following drawings is not intended to limit the scope of the claimed invention, but merely represents a selected embodiment of the present invention. Based on the drawings and embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0023] It should be noted that the terms "comprises", "includes" or any other variations are intended to cover non-exclusive inclusion, so that a process, element, method, article or equipment that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to the process, element, method, article or equipment.

[0024] The features and performances of the present invention are further described in detail below in conjunction with the embodiments.

[0025] Example 1 like Figure 1 and Figure 2 As shown, the present invention discloses a video detection fault processing device for an isolating switch, comprising a video sensor 4, a temperature sensor 5, a GIS control cabinet, a video server, a controllable switch, a processor and a power supply.

[0026] An observation window 2 is installed on the GIS disconnect switch equipment body, and the video sensor 4 collects the image information of the disconnect switch contacts through the observation window 2 , and the temperature sensor 5 collects the temperature of the video sensor 4 .

[0027] The signal lines of all sensors are connected to the video server through a controllable switch, the power lines of the sensors are connected to the power supply through a controllable switch, and the processor collects the auxiliary contact node status of the isolation switch through the secondary node in the GIS control cabinet. The processor controls the start or close of the controllable switch and determines the position of the isolation switch through the collected video, temperature, and auxiliary contact node status, and finally realizes intelligent judgment on whether the isolation switch has a fault in the opening and closing position.

[0028] The auxiliary contacts of the isolating switch act like a transfer switch, with a number of normally open and normally closed nodes that change position with the opening and closing positions of the isolating switch.

[0029] The auxiliary contact node status of the disconnector is as follows: Closed state: Indicates that the disconnector is in the on position and current can flow normally. For example, when the power system is operating normally, the auxiliary contacts of the disconnector are in the closed state to transmit the signal that the disconnector has been closed to the control system, thereby ensuring the normal operation of related equipment.

[0030] Disconnected state: means that the isolating switch is in the disconnected position, cutting off the current path. For example, when the equipment is overhauled or maintained, the isolating switch is operated to the disconnected position, and its auxiliary contacts are also in the disconnected state accordingly, sending a signal to the monitoring system that the isolating switch has been opened to ensure the safety of personnel and equipment.

[0031] like Figure 1 As shown, the controllable switch is arranged on the line connecting the video sensor 4 and the video server, and on the line connecting the video sensor 4 and the power supply.

[0032] The controllable switch is used to disconnect the electrical connection between the video sensor 4 and the video server. When the video sensor 4 needs to be started, the controllable switch contact is closed, the signal line of the video sensor 4 is connected to the video server signal, and the power line of the video sensor 4 is connected to the power supply. When the video sensor 4 is not started, the controllable switch contact is disconnected, so that the video sensor 4 is completely disconnected.

[0033] The present invention uses a controllable switch to connect the sensor installed on the primary body of the GIS with the wires of the background secondary equipment, and determines the current isolation position through the auxiliary contacts of the isolation switch. The switch connection wire is opened only when the GIS is running stably and safely, and the video monitoring system is started to avoid the interference of VFTO on the background equipment.

[0034] Example 2 Based on Example 1, the layout structure of the sensor is optimized.

[0035] Since the sensor is used outdoors, the metal protective shell has a high protection level and no heat dissipation channel, so the heat generated by the light source 8 cannot be dissipated quickly. The present invention uses a temperature sensor 5 to monitor the working temperature of the video sensor 4. When high temperature is found, the video sensor 4 is stopped in time to extend the working life of the video sensor 4.

[0036] like Figure 2 As shown, the observation window 2 is fixed at the opening of the GIS disconnector. The observation window 2 is two transparent organic glasses embedded in the metal shell 1. The light source 8 and the video sensor 4 illuminate and collect images through the organic glasses. The light source 8, the video sensor 4, the temperature sensor 5, the power module 7, the protection circuit 6 and other electronic devices are integrated in the metal shell 1. The temperature sensor 5 measures the working temperature of the video sensor 4, the protection circuit 6 provides an anti-interference circuit for each device, and the power module 7 receives the main power supply and supplies power to the sensor and the light source 8.

[0037] The protection circuit 6 is a prior art, mainly an anti-interference circuit and an overvoltage and overcurrent protection circuit 6, which reduces the impact of the voltage mutation of the primary body on the secondary equipment.

[0038] The video sensor 4 can be an infrared camera or a visible light camera. The infrared camera can be used to capture both thermal images and video images, and does not require a light source 8, so it can be used directly. The infrared camera can be extended by an optical fiber, and the optical fiber is aligned with the observation window 2, so that the camera can be prevented from being connected to the primary body.

[0039] Since there is no light source 8 inside the GIS, if a visible light camera is used, a light source 8 is required. The scattered light source 8 cannot be transmitted through the optical fiber, so the visible light camera cannot be extended using the optical fiber and can only be placed close to the observation window 2.

[0040] Figure 2 The power module 7 is used to receive power from the background and filter out interference in the power transmission line.

[0041] Specifically, Figure 2 As shown, a partition 3 is installed in the metal housing 1, and a video sensor 4 and a light source 8 are respectively fixed on both sides of the partition 3. The light source 8 and the video sensor 4 are fastened to the partition 3 to avoid displacement caused by vibration, etc. After the focal length is debugged in the factory test, the fastened installation can ensure that the focal length does not need to be readjusted after transportation to the project site.

[0042] Example 3 like Figure 3 As shown, the present invention discloses a method for processing a disconnect switch video detection fault, comprising the following steps: S1. The processor monitors the auxiliary contact node status of the isolating switch in the GIS control cabinet and obtains the auxiliary contact node status of the isolating switch.

[0043] Based on the state of the auxiliary contact node, it is judged whether the isolating switch is in the process of opening and closing. If so, the video sensor 4 is controlled to be in the disconnected state; the disconnected state is to disconnect all the power lines and signal lines of the video sensor 4; If not, start S2; S2, determine whether the current time of the disconnector is longer than the preset time from the last opening and closing operation; If not, the video sensor 4 is kept in the disconnected state; if so, the video sensor 4 is controlled to be in the connected state, and S3 is started; the connected state is to connect all the power lines and signal lines of the video sensor 4; S3, obtaining the temperature of the video sensor 4, and determining whether the temperature of the video sensor 4 exceeds a preset temperature; If not, the video sensor 4 acquires video information; If yes, the video sensor 4 is turned off, and when the temperature drops below the preset temperature, the video sensor 4 is turned on, and the video sensor 4 acquires the video information; S4: Process the video information, identify the contact position status of the isolating switch, and compare it with the auxiliary contact node status of the isolating switch obtained in S1. If the information of the two is inconsistent, an error alarm is issued.

[0044] In S1 and S2, when the isolating switch is in the process of opening and closing operation or the isolating switch is operated within N seconds, in order to avoid the conduction interference of VFTO, the controllable switch is not allowed to be opened, and the sensor and the background server are kept in a disconnected state. Waiting for the isolating switch to meet the conditions of opening and closing operation after N seconds, the video sensor 4 can be started.

[0045] Specifically, in S2, if it is determined that the current time of the isolating switch is longer than the preset time from the most recent opening and closing operation, it means that the isolating switch meets the opening and closing operation condition N seconds later. The controllable switch can be opened, the signal line and the power line between the video sensor 4 and the video server are connected, the power supply is started to energize the temperature sensor 5, and the temperature of the video sensor 4 is obtained.

[0046] Specifically, in S3, the temperature of the video sensor 4 is determined. If the temperature is too high, exceeding the preset temperature T, the power is turned off and waits for M seconds for natural cooling, or the operator is informed to take cooling measures and wait until the temperature is lower than the preset temperature T, then the video sensor 4 can be started.

[0047] When the temperature of the video sensor 4 is lower than the preset temperature T, the video sensor 4 is started to record M seconds of video, and the processor intelligently performs image analysis to determine the state of the disconnector contacts through the video image.

[0048] Specifically, in S4, the auxiliary contact node state of the isolating switch in the GIS control cabinet is compared with the isolating switch contact state identified by the processor. If the video image determines that the isolating switch contact state is in the open state, the auxiliary contact node state is determined to be in the closed state; or if the video image determines that the isolating switch contact state is not in the closed state, the auxiliary contact node state is determined to be in the closed state, that is, when the two judgments are inconsistent, an error alarm is issued.

[0049] Because of VFTO, the video sensor 4 cannot be turned on for a long time. After the video sensor 4 is turned on for M seconds, the fault judgment is completed, the power is turned off, the controllable switch is disconnected, and the next startup is waited.

[0050] In summary, the video sensor 4 is not allowed to be started during the opening and closing action, within N seconds after the action, or when the ambient temperature of the video sensor 4 is too high. The video sensor 4 is disconnected from the background video server through a controllable switch.

[0051] Example 4 There are three ways to start the video monitoring system next time, namely, timed start, start after a preset time after the isolating switch is actuated, and manual start by the operation and maintenance personnel.

[0052] The first type, timed start: after the current video recording is finished, the video monitoring process will be automatically started after the first time, and the process will jump to S1; The second type is to start after a preset time after the isolating switch is actuated: the processor monitors the isolation position status through the auxiliary contact node information of the isolating switch in the control cabinet. Once the isolating switch is detected to be opened or closed, the video monitoring process will be automatically started after a second time.

[0053] The purpose of this design is to start the video monitoring process immediately after the disconnector is actuated, capture the disconnector contact image, identify the disconnector position in the image, and report in time if the disconnector contact position is incorrect. Without this mechanism, if there is a fault after the disconnector is actuated, it will take until the next timing moment to identify it, and the fault cannot be discovered in time.

[0054] The third type is manual start by the operation and maintenance personnel. During operation, if the operation and maintenance personnel want to view the current contact image, they manually start the video monitoring process.

[0055] Traditional video monitoring is continuous monitoring. Since the video sensor 4 is installed on the GIS body, in an outdoor, strong electromagnetic environment, good protection and shielding are guaranteed. The video sensor 4 and the light source 8 are installed in a closed protective shell. The heat generated by the light source 8 during operation cannot be quickly dissipated. If it is operated for a long time, the video sensor 4 will reduce its working life due to high temperature or even be directly damaged. Therefore, each time the video monitoring process is started, only short-term video data is collected to prevent the temperature in the sensor protective shell from being too high due to long-term shooting. After shooting, disconnect the sensor from the background electrical connection to allow it to cool down slowly and wait for the next start.

[0056] Example 5 like Figure 4 As shown, the present invention also discloses a disconnector video detection fault processing system, comprising: A data acquisition module, used to obtain the auxiliary contact node status of the disconnector; A switch-on / off state judgment module, used to judge whether the disconnector is in the switch-on / off process based on the auxiliary contact node state, and if so, control the video sensor 4 to be in the disconnected state; If not, start the time judgment module; The time judgment module is used to judge whether the time between the isolating switch and the most recent operation exceeds the preset time. If not, the video sensor 4 is kept in the disconnected state; if so, the video sensor 4 is controlled to be connected and the temperature comparison module is started; A temperature comparison module, used to obtain the temperature of the video sensor 4 and determine whether the temperature of the video sensor 4 exceeds a preset temperature; If not, the video sensor 4 acquires video information; If yes, the video sensor 4 is turned off, and when the temperature drops below the preset temperature, the video sensor 4 is turned on, and the video sensor 4 acquires the video information; The identification and judgment module is used to process video information, identify the contact position status of the isolating switch, and compare it with the auxiliary contact node status of the isolating switch. If the information of the two is inconsistent, an error alarm is issued.

[0057] Example 6 The present invention also discloses a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, the isolating switch video detection fault processing method is implemented. The memory may include a memory, such as a high-speed random access memory, and may also include a non-volatile memory, such as at least one disk memory, etc. The processor, the network interface, and the memory are interconnected through an internal bus. The internal bus may be an industrial standard architecture bus, a peripheral component interconnection standard bus, an extended industrial standard structure bus, etc. The bus may be divided into an address bus, a data bus, a control bus, etc. The memory is used to store programs. Specifically, the program may include a program code, and the program code includes computer operation instructions. The memory may include a memory and a non-volatile memory, and provide instructions and data to the processor.

[0058] Example 7 The present invention also discloses a computer-readable storage medium, wherein the computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, the isolating switch video detection fault processing method is implemented. Specifically, the computer-readable storage medium includes, but is not limited to, for example, a volatile memory and / or a non-volatile memory. The volatile memory may include a random access memory and / or a cache memory, etc. The non-volatile memory may include a read-only memory, a hard disk, a flash memory, an optical disk, a magnetic disk, etc.
