[0042] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0044] Figure 1Schematic diagram of a state monitoring system for a switch-on and switch-off pressure plate provided by an embodiment of the present invention. This embodiment can be applied to monitoring the state of a switch-on and switch-off pressure plate in a power system, such as Figure 1 As shown, the state monitoring system 100 of the opening and closing pressure plate includes: an acquisition module 1 and a processing module 2; the acquisition module 1 is used to acquire the working parameters of multiple opening and closing pressure plates 3; wherein the working parameters include the position parameters and pulse parameters of the opening and closing pressure plates 3; the input end of the processing module 2 is connected to the output end of the acquisition module 1, and is used to determine the initial working state of the multiple opening and closing pressure plates 3 according to the position parameters and the pulse parameters.

[0045] Specifically, the opening and closing pressure plate 33 is a key component in the power system for controlling the tripping and closing of the circuit breaker. It receives signals from the protection device or control system to perform tripping or closing operations, thereby ensuring the safe and stable operation of the power system. When the opening and closing pressure plate 3 is not put into or withdrawn according to the regulations, it is very likely that the power system cannot be started normally as expected. Therefore, real-time status monitoring of the opening and closing pressure plate 3 is crucial to the safe and stable operation of the power system. The state monitoring system provided in this embodiment collects the working parameters of multiple opening and closing pressure plates 3 through the acquisition module 1 and sends them to the processing module 2. The working parameters of each opening and closing pressure plate 3 include the position parameter and pulse parameter of the opening and closing pressure plate 3, wherein the position parameter can be an identity mark of the opening and closing pressure plate 3, which is used to distinguish different opening and closing pressure plates 3 during the monitoring process, thereby ensuring that the processing module 2 can accurately determine the initial working state of different opening and closing pressure plates 3; the pulse parameter can be a pulse signal containing the information of the opening and closing pressure plate 3 being put in or out, and the processing module 2 can determine the opening and out state of the opening and closing pressure plate 3 at this time by analyzing the pulse parameters collected by the acquisition module 1. Based on the position parameter, the processing module 2 compares the opening and out state corresponding to the position parameter with the preset state. If the opening and out state corresponding to the position parameter is the same as the preset state, it is determined that the initial working state of the opening and closing pressure plate 3 represented by the position parameter is normal; if the opening and out state corresponding to the position parameter is different from the preset state, it is determined that the initial working state of the opening and closing pressure plate 3 represented by the position parameter is abnormal, thereby realizing real-time monitoring of the state of the opening and closing pressure plate 3.

[0046] Exemplarily, the position parameter can be stored in the electronic tag, and the pulse parameter can include a low-level pulse signal and a high-level pulse signal, wherein the low-level pulse signal indicates that the opening and closing switch is in the exit state, and the high-level pulse signal indicates that the opening and closing switch is in the input state. When the opening and closing switch is monitored in real time, the acquisition module 1 obtains the position parameter of the opening and closing pressure plate by reading the information in the electronic tag, and collects the pulse parameter of the opening and closing pressure plate at this time, and outputs the position parameter and the pulse parameter to the processing module 2 to determine the opening and closing state of the opening and closing switch. The processing module 2 can compare the opening and closing state under the position parameter with the preset state based on the internally stored position parameter-preset state table to determine the initial working state of the opening and closing pressure plate. If the pulse parameter collected by the opening and closing switch A corresponding to the position parameter is a low-level pulse signal, the processing module 2 determines that the opening and closing state of the opening and closing switch A is the exit state, and the preset state of the opening and closing switch A is queried according to the position parameter as the input state. The processing module 2 compares the opening and closing state of the opening and closing switch A and finds that it is different from the preset state, thereby determining that the initial working state of the opening and closing switch A is abnormal; if the pulse parameter collected by the opening and closing switch B corresponding to the position parameter is a high-level pulse signal, the processing module 2 determines that the opening and closing state of the opening and closing switch B is the input state, and the preset state of the opening and closing switch B is queried according to the position parameter as the input state. The processing module 2 compares the opening and closing state of the opening and closing switch B and finds that it is the same as the preset state, thereby determining that the initial working state of the opening and closing switch B is normal.

[0047] In this embodiment, the acquisition module acquires the position parameters and pulse parameters of the multiple opening and closing pressure plates and outputs them to the processing module, so that the processing module can determine the initial working states of the multiple opening and closing pressure plates according to the position parameters and pulse parameters, thereby realizing real-time monitoring of the states of the multiple opening and closing pressure plates. The real-time monitoring of the working states of the opening and closing pressure plates avoids the problem of untimely monitoring of the states of the opening and closing pressure plates due to manual inspection and maintenance, improves the timeliness and accuracy of the monitoring of the states of the opening and closing pressure plates, and ensures the reliability and safety of the power system.

[0048] Based on the above embodiments, Figure 2 is a structural schematic diagram of another state monitoring system for a closing and opening pressure plate provided by an embodiment of the present invention, Figure 2 The timing module in the state monitoring system of the opening and closing pressure plate is explained. Figure 2 As shown, the status monitoring system also includes a timing module 4; the input end of the timing module 4 is connected to the acquisition module 1, and the output end is connected to the processing module 2, which is used to record the acquisition time of the pulse parameters and output the acquisition time to the processing module 2; the processing module 2 is also used to determine the initial working state of the opening and closing pressure plate 3 based on the acquisition time according to the acquisition time, position parameters and pulse parameters.

[0049] Specifically, the power system may have different requirements for the on / off state of the same opening and closing switch in different time zones, that is, the preset state of the same opening and closing switch is different in different time zones, and thus the processing module 2 determines the working state of the opening and closing pressure plate 3 based on the pulse parameters collected by the acquisition module 1. Therefore, when the acquisition module 1 collects the pulse parameters of the opening and closing pressure plate 3, the trigger timing module 4 records the current acquisition time and outputs it to the processing module 2. The processing module 2 can determine the time zone in which it is located according to the acquisition time, and match the position parameter-preset state table with the on / off state according to the time zone. After the processing module 2 determines the on / off state of the opening and closing switch at this time according to the pulse parameters, it compares the position parameter-preset state table corresponding to the time zone in which the acquisition time is located with the real-time detected position parameters and on / off state, and determines the initial working state of the opening and closing pressure plate 3 based on the acquisition time.

[0050] Exemplarily, a day can be divided into three time zones, namely 0:00-7:59, 8:00-15:59 and 16:00-23:59. Position parameter-preset state table A, position parameter-preset state table B and position parameter-preset state table C corresponding to the three time zones can be pre-set in processing module 2, wherein each position parameter-preset state table is set based on the requirements for the throw-in and throw-out states of the opening and closing switches under multiple position parameters in the time zone, that is, it includes multiple preset states corresponding to multiple position parameters in the time zone. When the acquisition module 1 acquires the position parameters and pulse parameters of the opening and closing pressure plate A, the trigger timing module 3 records the current acquisition time and outputs it to the processing module 2. For example, the acquisition time received by the processing module 2 is 6:45, and it is determined that the current acquisition time is in the time zone of 0:00-7:59, then the position parameter-preset state table A is matched as a reference table for determining the initial working state of the opening and closing pressure plate A. After the processing module 2 determines the throw-in / out state of the opening / closing pressure plate A according to the pulse parameter, the preset state corresponding to the position parameter is queried based on the position parameter, and then the processing module 2 determines the initial working state of the opening / closing pressure plate A at this time according to whether the throw-in / out state is the same as the preset state. It should be noted that the above is only an exemplary division of a time zone, and is not a specific limitation of this embodiment.

[0051] This embodiment records the collection time of the opening and closing pressure plate through the timing module, and then the processing module matches the state requirements of the opening and closing pressure plate according to the collection time, and determines the initial working state of the opening and closing pressure plate based on the collection time according to the state requirements of the opening and closing pressure plate at this time, thereby improving the accuracy of the opening and closing pressure plate monitoring.

[0052] Based on the above embodiments, Figure 3 is a structural schematic diagram of another state monitoring system for a closing and opening pressure plate provided by an embodiment of the present invention, Figure 3The control module in the state monitoring system of the opening and closing pressure plate is described. Figure 3 As shown, the state monitoring system also includes a control module 5; the input end of the control module 5 is connected to the output end of the processing module 2, and the output end is connected to the opening and closing pressure plate 3, which is used to adjust the initial working state of the opening and closing pressure plate 3 according to the initial working state and the preset demand state.

[0053] Specifically, the processing module 2 can determine the throw-in / out state of the opening and closing pressure plate 3 at this time according to the pulse parameters collected by the processing module 2 through the analysis of the acquisition module 1. Based on the position parameter, the processing module 2 compares the throw-in / out state corresponding to the position parameter with the preset state. If the throw-in / out state corresponding to the position parameter is the same as the preset state, it is determined that the initial working state of the opening and closing pressure plate 3 represented by the position parameter is normal; if the throw-in / out state corresponding to the position parameter is different from the preset state, it is determined that the initial working state of the opening and closing pressure plate 3 represented by the position parameter is abnormal, and then the processing module 2 sends the determined initial working state and the preset demand state of the opening and closing pressure plate 3 to the control module 5, and the control module 5 adjusts the initial working state of the opening and closing pressure plate 3 according to the received initial working state and the preset demand state. When the initial working state is normal, the control module 5 does not adjust the initial working state of the opening and closing pressure plate 3; when the initial working state is abnormal, the control module 5 adjusts the initial working state of the opening and closing pressure plate 3 to the preset demand state according to the preset demand state.

[0054] Exemplarily, when the opening and closing pressure plate A is in the engaged state and the processing module 2 determines that the initial working state of the opening and closing pressure plate A is abnormal, the preset required state of the opening and closing pressure plate A is called the exit state, and the abnormal initial working state and the preset required state are output to the control module 5. After the control module 5 identifies the abnormal initial working state signal of the opening and closing pressure plate A, it generates a control signal based on the exit state, and then controls the opening and closing pressure plate A to be adjusted from the engaged state to the exit state, so that the initial working state of the opening and closing pressure plate A is adjusted from abnormal to normal.

[0055] In this embodiment, when the control module detects that the opening and closing pressure plate is in an abnormal working state, the real-time on / off state of the opening and closing pressure plate is adjusted based on the preset demand state of the opening and closing pressure plate, so that the opening and closing pressure plate can participate in the system operation normally and in a timely manner, thereby avoiding the abnormal working state of the opening and closing pressure plate that causes the power system to be unable to start normally as expected, thereby improving the reliability and safety of the power system.

[0056] Based on the above embodiments, Figure 4 is a structural schematic diagram of another state monitoring system for a closing and opening pressure plate provided by an embodiment of the present invention, Figure 4 The control module in the state monitoring system of the opening and closing pressure plate is described. Figure 4As shown, the status monitoring system also includes a warning module 6; the initial working state includes a normal working state and an abnormal working state; the warning module 6 is connected to the processing module 2 and is used to issue a warning reminder when the working state is an abnormal working state.

[0057] Specifically, when the processing module 2 determines that the throw-in / out state corresponding to the position parameter is different from the preset state, it determines that the initial working state of the opening and closing pressure plate 3 represented by the position parameter is an abnormal working state; when the processing module 2 determines that the throw-in / out state corresponding to the position parameter is the same as the preset state, it determines that the initial working state of the opening and closing pressure plate 3 represented by the position parameter is a normal working state. When the processing module 2 determines that the initial working state of the opening and closing pressure plate 3 is an abnormal working state, a warning signal is generated and output to the warning module 6. The warning module 6 issues a warning reminder according to the warning signal. The warning reminder may include but is not limited to at least one of a voice reminder, a buzzer reminder, a light reminder, etc., and this embodiment does not specifically limit this.

[0058] In this embodiment, when the processing module determines that the opening and closing pressure plate is in an abnormal working state, a warning reminder is issued through the warning module, so that the staff can be informed of the abnormal working state of the opening and closing pressure plate in time and adopt corresponding countermeasures to improve the safety of power system operation.

[0059] Optional, Figure 5 is a schematic diagram of a warning module provided by an embodiment of the present invention, referring to Figure 5 The warning module 6 includes a light unit 61 and a sound unit 62; the light unit 61 is used to emit a first color warning light when the initial working state is a normal working state; and emit a second color warning light when the initial working state is an abnormal working state; the sound unit 62 is used to emit a first warning sound when the initial working state is a normal working state; and emit a second warning sound when the initial working state is an abnormal working state; the frequency of the second warning sound is greater than the frequency of the first warning sound.

[0060] Specifically, when the processing module 2 determines that the initial working state of the opening and closing pressure plate 3 is a normal working state, the light unit 61 is controlled to emit a first color warning light and the sound unit 62 is controlled to emit a first warning sound; when the processing module 2 determines that the initial working state of the opening and closing pressure plate 3 is an abnormal working state, the light unit 61 is controlled to emit a second color warning light and the sound unit 62 is controlled to emit a second warning sound, wherein the frequency of the second warning sound is greater than the frequency of the first warning sound, so that when the initial working state of the opening and closing pressure plate is an abnormal working state, the sound unit 62 can provide a stronger sound warning reminder, which is convenient for the staff to promptly discover the abnormal state of the opening and closing pressure plate, thereby improving the monitoring efficiency and the operation safety of the power system.

[0061] Exemplarily, the first color may be green, the second color may be red, the first warning sound may be an intermittent beep, and the second warning sound may be a continuous beep, which is not specifically limited in this embodiment.

[0062] Based on the above embodiments, Figure 6 is a structural schematic diagram of another state monitoring system for a closing and opening pressure plate provided by an embodiment of the present invention, Figure 6 The digital management module in the state monitoring system of the opening and closing pressure plate is described. Figure 6 As shown, the state monitoring system also includes a digital management module 7; the input end of the digital management module 7 is connected to the output end of the acquisition module 1, and the output end is connected to the processing module 2, for converting the working parameters into analog signals and outputting them to the processing module 2.

[0063] Specifically, the digital management module 7 can be a digital-to-analog converter, which converts the working parameters in the form of digital signals into continuous analog signals and outputs them to the processing module 2. It adopts efficient digital quantity processing technology, can automatically process large amounts of data, and can quickly process and analyze data, thereby significantly improving management efficiency and greatly reducing the time and cost of manual operations, ensuring that the digital parameters output by the acquisition module 1 can be correctly identified and executed by the processing module 2, thereby determining the initial working state of the opening and closing pressure plate.

[0064] This embodiment sets the digital management module between the acquisition module and the processing module, so that the digital signal output by the acquisition module can be converted into an analog signal and transmitted to the processing module, thereby reducing electromagnetic interference in the transmission process of working parameters, improving the accuracy of monitoring the status of the opening and closing pressure plate, and reducing the time and cost of manual operation.

[0065] Based on the above embodiments, Figure 7 is a structural schematic diagram of another state monitoring system for a closing and opening pressure plate provided by an embodiment of the present invention, Figure 7 The communication module in the state monitoring system of the opening and closing pressure plate is described. Figure 7 As shown, the status monitoring system further includes a communication module 8 ; the communication module 8 connects the processing module 2 and the terminal 9 , and is used to establish a communication connection between the processing module 2 and the terminal 9 , so that the processing module 2 transmits an initial working state to the terminal 9 .

[0066] Specifically, the terminal 9 can be a main station of the power grid, and the communication module 8 can use wired or wireless communication technology to connect the processing module 2 and the terminal 9, so that the staff can promptly know whether the initial working state of the opening and closing pressure plate is normal. Exemplarily, when the communication module 8 connects the processing module 2 and the terminal 9 through wired communication technology, Ethernet, RS-232, RS-485 or universal serial bus can be used; when the communication module 8 connects the processing module 2 and the terminal 9 through wireless communication technology, WIFI technology, ZigBee technology, LoRa technology, 4G technology or 5G technology can be used, and this embodiment does not specifically limit this.

[0067] This embodiment realizes the communication connection between the processing module and the terminal through the communication module, realizes real-time, remote and accurate monitoring of the status of the opening and closing pressure plate, improves the monitoring efficiency of the opening and closing pressure plate, and enhances the power system's rapid response capability and operational stability to potential risks during the operation of the opening and closing pressure plate.

[0068] Optional, Figure 8 is a structural schematic diagram of another state monitoring system for a closing and opening pressure plate provided by an embodiment of the present invention, with reference to Figure 8 The status monitoring system further includes an encryption module 10; the encryption module 10 is disposed between the communication module 8 and the terminal 9, and is used for encrypting the initial working status.

[0069] Specifically, the encryption module 10 can be a 4G encryption module, which is used to encrypt the initial working state of the transmission to ensure the security and privacy of the data during the transmission process. Through advanced encryption algorithms, it can effectively prevent data from being illegally stolen, tampered with or leaked. The 4G encryption module supports a variety of communication protocols, including commonly used network protocols such as TCP / IP. The communication method between the 4G encryption module and the terminal 9 is wireless communication. The wireless communication method has the advantages of high flexibility, strong scalability and low cost-effectiveness. The 4G encryption module and the terminal 9 can realize real-time data transmission between the communication module 8 and the terminal 9 by using the high-speed transmission characteristics of the 4G network. Whether it is monitoring video, real-time data or control instructions, the transmission can be completed in a short time, which improves the response speed and efficiency of the state monitoring system. The 4G encryption module and the terminal 9 use wireless communication, and the terminal 9 can remotely monitor and control the equipment connected to the 4G encryption module. In emergency situations such as natural disasters and emergencies, wired communications may be damaged or interrupted, and the wireless communication between the 4G encryption module and the terminal 9 can provide reliable communication guarantee in this case, ensuring the timely transmission of the initial working state of the opening and closing pressure plate and the accurate execution of the instructions issued by the terminal 9.

[0070] Based on the above embodiments, Fig. 9is a structural diagram of a collection module provided by an embodiment of the present invention, Fig. 9 The acquisition module in the state monitoring system of the opening and closing pressure plate is described. Fig. 9 As shown, the acquisition module 1 includes a position sensing unit 11 and a pulse acquisition unit 12; the position sensing unit 11 is used to acquire the position parameters of the opening and closing pressure plate 3; the pulse acquisition unit 12 is connected to the opening and closing pressure plate 3 and is used to acquire the pulse parameters of the opening and closing pressure plate 3.

[0071] Specifically, the position parameters of the opening and closing pressure plate 3 can be stored in an electronic tag, such as a QR code. When monitoring the state of the opening and closing pressure plate, the position sensing unit 11 can capture the image of the QR code and recognize the QR code, thereby extracting the position parameters of the opening and closing pressure plate; the pulse acquisition unit 12 is connected to the two contacts of the opening and closing pressure plate 3 through wiring, wherein, before connecting the pulse acquisition unit 12 and the opening and closing pressure plate 3, it is necessary to check whether the two contacts of the opening and closing pressure plate 3 are clean, free of rust or damage, to ensure that the insulation between the contacts is good and there is no risk of short circuit, and then connect one end of the wire or cable to the corresponding terminal on the pulse acquisition unit 12, and connect the other end of the wire or cable to the two contacts of the opening and closing pressure plate 3, so that the pulse acquisition unit 12 can accurately collect the pulse parameters of the opening and closing pressure plate 3.

[0072] This embodiment collects the position parameters of the opening and closing pressure plate through the position sensing unit, and collects the pulse parameters of the opening and closing pressure plate through the pulse collection unit, thereby realizing online status monitoring of multiple opening and closing pressure plates, improving the monitoring efficiency of the opening and closing pressure plates, and greatly reducing the time and cost of manual operation.

Fig.10 As shown, the state monitoring system further includes a power module 13 ; the power module 13 is connected to the acquisition module 1 and the processing module 2 respectively, and is used to provide electric energy to the acquisition module 1 and the processing module 2 .

[0074] Specifically, the power module 13 can be composed of a lithium battery, a solar photovoltaic panel and a power management chip. The power management chip is responsible for monitoring, controlling and protecting the lithium battery to ensure the safety of the battery and the stability of the power supply of the insulating leakage device. When the sun is abundant, the power generation efficiency of the photovoltaic panel is sufficient to meet the daily power demand of the insulating leakage device. At this time, the photovoltaic panel directly supplies power to the insulating leakage device. However, once the power demand of the insulating leakage device increases, the photovoltaic panel cannot maintain a stable voltage output, and the power management chip will mobilize the lithium battery to supply power in coordination to ensure the continuous and stable operation of the insulating leakage device. In addition, when the power of the lithium battery is lower than the safety threshold, the photovoltaic panel will automatically switch to charging mode to replenish the lithium battery. In the face of thunderstorms or night time, the power generation efficiency of the photovoltaic panel drops significantly and cannot meet the voltage requirements of the insulating leakage device. At this time, the lithium battery assumes the main power supply responsibility to ensure the uninterrupted operation of the insulating leakage device.

[0075] In this embodiment, the power module is used to supply power to each module in the state monitoring system of the opening and closing pressure plate, thereby improving the stability and flexibility of the operation of the state monitoring system of the opening and closing pressure plate.

[0076] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
