[0002] Surge arresters are an indispensable type of equipment in power systems, protecting electrical equipment from high transient overvoltages. During the discharge process, surge arresters are subjected to current surges, therefore it is necessary to monitor the leakage current generated by these surges and continuously record the number of times the arrester operates under these surges. Currently, monitoring of surge arresters is only performed in narrowband environments, resulting in limited current change data and making it difficult to comprehensively capture the detailed process of current changes. Summary of the Invention

A wake-up command is sent through the narrowband network to control the surge arrester monitoring device to switch from the shallow sleep state to the wake-up state. After receiving the monitoring data reported by the surge arrester monitoring device through the broadband network, the surge arrester monitoring device is controlled to switch from the wake-up state to the deep sleep state; In the deep sleep state, the narrowband module operates in a timed connection state; in the shallow sleep state, the narrowband module operates in a long connection state; and in the wake-up state, the broadband module operates in a long connection state.

If no response signal is received within the preset response time for sending the state switching command, the state switching of the surge arrester monitoring device is determined to have failed, and the process returns to the step of sending the state switching command to the narrowband module via the narrowband network based on the message queue telemetry transmission protocol.

[0007] In some embodiments, the number of surge arrester monitoring devices is multiple, and the step of sending a wake-up command through the narrowband network to control the surge arrester monitoring devices to switch from the shallow sleep state to the wake-up state includes: The wake-up command is sent cyclically to multiple surge arrester monitoring devices through the narrowband network.

[0009] In some embodiments, the control system includes a database and a file library. After sending a wake-up command via the narrowband network to switch the surge arrester monitoring device from the shallow sleep state to the wake-up state, the control method further includes: After receiving the monitoring data reported by the surge arrester monitoring device through the broadband network, the monitoring data is processed to determine the key data corresponding to the monitoring data. The key data includes any one or more of the extreme values, average values, and variances of the monitoring data. The key data is stored in the database, and the monitoring data is converted into monitoring files and saved to the file library.

[0010] The control device of this application embodiment is applied to a control system, wherein the control system is connected to a narrowband module of a surge arrester monitoring device via a narrowband network and to a broadband module of the surge arrester monitoring device via a broadband network, and the control device includes: The first control module is used to send a state switching command through the narrowband network to control the surge arrester monitoring device to switch from deep sleep state to shallow sleep state. The second control module is used to send a wake-up command through the narrowband network to control the surge arrester monitoring device to switch from the shallow sleep state to the wake-up state. The third control module is used to control the surge arrester monitoring device to switch from the wake-up state to the deep sleep state after receiving the monitoring data reported by the surge arrester monitoring device through the broadband network; In the deep sleep state, the narrowband module operates in a timed connection state; in the shallow sleep state, the narrowband module operates in a long connection state; and in the wake-up state, the broadband module operates in a long connection state.

Detailed Implementation

[0019] The embodiments of this application will be further described below with reference to the accompanying drawings. The same or similar reference numerals in the drawings denote the same or similar elements or elements having the same or similar functions throughout. Furthermore, the embodiments of this application described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of this application, and should not be construed as limiting this application.

[0020] Please see Figure 1 and Figure 2 This application provides a control method. The control method is applied to a control system 100, which is connected to a narrowband module 210 of a surge arrester monitoring device 200 via a narrowband network and to a broadband module 220 of the surge arrester monitoring device 200 via a broadband network. The control method includes: 010: Send a state switching command via narrowband network to control the surge arrester monitoring device 200 to switch from deep sleep state to shallow sleep state; 020: Send a wake-up command via narrowband network to control the surge arrester monitoring device 200 to switch from shallow sleep state to wake-up state; 030: After receiving the monitoring data reported by the surge arrester monitoring device 200 through the broadband network, control the surge arrester monitoring device 200 to switch from the wake-up state to the deep sleep state; In deep sleep mode, the narrowband module 210 operates in a timed connection state; in shallow sleep mode, the narrowband module 210 operates in a long connection state; and in wake-up mode, the broadband module 220 operates in a long connection state.

[0021] In the control method of this application, the surge arrester monitoring device 200 is in a deep sleep state. A state switching command is sent to control the surge arrester monitoring device 200 to switch from a deep sleep state to a shallow sleep state, keeping the narrowband module 210 continuously connected. Then, a wake-up command is sent to control the surge arrester monitoring device 200 to switch from a shallow sleep state to a wake-up state. After completing the reception of monitoring data, the surge arrester monitoring device 200 is controlled to switch back to a deep sleep state. In this way, while achieving the acquisition of millisecond-level monitoring data, the power consumption of the surge arrester monitoring device 200 can be saved, the number of battery replacements of the surge arrester monitoring device 200 can be reduced, and the operation and maintenance costs can be lowered.

[0022] Specifically, the control system 100 includes a server 10, which is connected to the surge arrester monitoring device 200 and used to control the surge arrester monitoring device 200. The control system 100 may also include an interactive interface, through which the surge arrester monitoring device 200 is controlled. The surge arrester monitoring device 200 includes a narrowband module 210 and a broadband module 220. The narrowband module 210 is connected to the server 10 via a narrowband network, and the broadband module 220 is connected to the server 10 via a broadband network.

[0023] Narrowband networks refer to low-bandwidth network connections, characterized by slower transmission speeds and lower power consumption, making them suitable for data transmission of small amounts of data. Broadband networks refer to high-bandwidth network connections, characterized by faster transmission speeds and higher power consumption, making them suitable for data transmission of large amounts of data.

[0024] The surge arrester monitoring device 200 can be applied in substations, converter stations and other scenarios. Taking a converter station as an example, when the power is cut off, a large instantaneous current may be generated. This current will be discharged through the surge arrester. The surge arrester monitoring device 200 is used to monitor the surge arrester during the power outage maintenance of the converter station, so as to improve the safety of the power outage maintenance process.

[0025] When the surge arrester monitoring device 200 is not required to perform monitoring tasks, it is in deep sleep mode. In deep sleep mode, the narrowband module 210 operates on a timed connection basis, meaning it connects to the control system 100's server 10 only once a day at a fixed time for time synchronization and other operations. The broadband module 220 is not connected.

[0026] When the surge arrester monitoring device 200 needs to perform a monitoring task, a state switching command can be sent to the narrowband module 210 via the narrowband network at a first preset time before the monitoring task is performed. The narrowband module 210, in a timed connection state, can listen in a time-division manner to receive the state switching command. The state switching command is used to switch the surge arrester monitoring device 200 from a deep sleep state to a shallow sleep state. In the shallow sleep state, the narrowband module 210 operates in a long-connection state, meaning that the narrowband module 210 is always connected to the server 10 of the control system 100, while the broadband module 220 is not connected.

[0027] It should be noted that the narrowband module 210 requires time to respond to state switching commands. In some cases, the response may be delayed by up to 24 hours, and there is a possibility that the state switching command may be lost. Therefore, the operation of sending the state switching command needs to be performed in advance of a first preset time. The first preset time can be set according to the actual application situation; for example, the first preset time can be 3 days, 4 days, 5 days, etc.

[0028] Subsequently, a wake-up command is sent to the narrowband module 210 via the narrowband network. The wake-up command is used to switch the surge arrester monitoring device 200 from a shallow sleep state to a wake-up state. In the wake-up state, both the narrowband module 210 and the broadband module 220 operate in a long-term connection state, meaning that both the narrowband module 210 and the broadband module 220 are always connected to the server 10 of the control system 100.

[0029] In the awakened state, the control system 100 can receive monitoring data reported by the surge arrester monitoring device 200 via a broadband network. Of course, a narrowband network can also be used for data transmission. It should be noted that to prevent duplicate command reception during data transmission, which could lead to execution errors, data transmission should only be performed through either the narrowband or broadband network. After the power outage maintenance is completed, i.e., the monitoring task is completed and the monitoring data has been reported, the control system switches the surge arrester monitoring device 200 from the awakened state to a deep sleep state.

[0030] The surge arrester monitoring device 200 monitors current change data. To better study the causes and patterns of current occurrence, it is desirable for the surge arrester monitoring device 200 to acquire millisecond-level current change data. However, the amount of data at the millisecond level is large, and it is necessary to report it using a broadband network. But the broadband module 220 consumes a lot of power, and the battery-powered surge arrester monitoring device 200 requires frequent battery replacements.

[0031] Furthermore, in the aforementioned application scenarios, the surge arrester monitoring device 200 is used infrequently, typically only once or twice a year in practice. Moreover, performing tasks such as battery replacement in substations and converter stations is extremely difficult. Related technologies only control the surge arrester monitoring device in narrowband environments, failing to obtain more detailed data on current changes.

[0032] In this embodiment, the surge arrester monitoring device 200 is kept in deep sleep mode most of the time, connecting to the server 10 only once a day at a fixed time for time synchronization and other operations, while simultaneously listening in a time-sharing manner to receive commands. When the surge arrester monitoring device 200 needs to perform a monitoring task, a state switching command is first sent to control the surge arrester monitoring device 200 to switch from deep sleep mode to shallow sleep mode, keeping the narrowband module 210 connected for a long time, so that it can quickly respond to the wake-up command later; then a wake-up command is sent to control the surge arrester monitoring device 200 to switch from shallow sleep mode to wake-up mode, and after completing the reception of monitoring data, the surge arrester monitoring device 200 can be controlled to switch back to deep sleep mode.

[0033] In this way, while acquiring millisecond-level monitoring data, the power consumption of the surge arrester monitoring device 200 can be saved, achieving the effect of not needing to replace the battery for several years. Studies have found that if the surge arrester monitoring device 200 is kept on for a long time for listening or connected to the network, the battery will be depleted in about one month and must be replaced. However, using the control method of the embodiment of this application, the battery of the surge arrester monitoring device 200 can be maintained for about 5 years.

[0034] Please see Figure 2 and Figure 3In some implementations, a state switching command is sent via a narrowband network to control the surge arrester monitoring device 200 to switch from a deep sleep state to a shallow sleep state (i.e., 010), including: 011: Through the narrowband network, a state switching command is sent to the narrowband module 210 based on the message queue telemetry transmission protocol. The state switching command is used to switch the narrowband module 210 from the timed connection state to the long connection state, so as to control the surge arrester monitoring device 200 to switch from the deep sleep state to the shallow sleep state. 012: Receive the response signal sent by the narrowband module 210 through the narrowband network based on the message queue telemetry transmission protocol to determine the state switching status of the surge arrester monitoring device 200; At this time, a wake-up command is sent via a narrowband network to control the surge arrester monitoring device 200 to switch from a shallow sleep state to a wake-up state (i.e., 020), including: 021: When the state switching of the surge arrester monitoring device 200 is successful, a wake-up command is sent through the narrowband network to control the surge arrester monitoring device 200 to switch from the shallow sleep state to the wake-up state.

[0035] Specifically, in deep sleep mode, the narrowband module 210 only connects to the server 10 periodically. Therefore, the state switching command must be transmitted through the narrowband network, and the state switching command needs to be stored in the wireless access point controller (AC) of the narrowband network for a period of time. Therefore, the message queuing telemetry transport (MQTT) protocol is used to send the state switching command.

[0036] The control system 100 includes a communication module. Inputting commands to switch the state of the surge arrester monitoring device 200 via the interactive interface notifies the communication module, which then sends a state switching command to the narrowband module 210 via a narrowband network based on a message queue telemetry transmission protocol. The state switching command sent by the control system 100 is stored on an MQTT server. The narrowband module 210 can actively retrieve the state switching command from the MQTT server when periodically connecting. Upon receiving the state switching command, the narrowband module 210 switches from a periodically connected state to a persistent connection state, causing the surge arrester monitoring device 200 to switch from a deep sleep state to a shallow sleep state.

[0037] After receiving a state switching command, the narrowband module 210 will send a response signal. Since the narrowband module 210 needs time to respond to the state switching command, and there is a possibility that the state switching command may be lost, the control system 100 can continuously monitor and receive the response signal sent by the narrowband module 210 through the narrowband network based on the message queue telemetry transmission protocol to determine the state switching status of the surge arrester monitoring device 200.

[0038] Please see Figure 2 In some implementations, receiving a response signal sent by the narrowband module 210 via a narrowband network based on a message queue telemetry transmission protocol to determine the state switching status (i.e., 012) of the surge arrester monitoring device 200 includes: If a response signal is received within the preset response time of sending the state switching command, the state switching of the surge arrester monitoring device 200 is determined to be successful. If no response signal is received within the preset response time for sending the state switching command, the state switching of the surge arrester monitoring device 200 is determined to have failed, and the process returns to the step of sending the state switching command to the narrowband module 210 via the narrowband network based on the message queue telemetry transmission protocol.

[0039] Specifically, within a preset response time after sending the state switching command, if the control system 100 receives a response signal sent by the narrowband module 210 based on the message queue telemetry transmission protocol, it determines that the state switching of the surge arrester monitoring device 200 is successful. Subsequently, when the surge arrester monitoring device 200 needs to perform a detection task, for example, when a power outage maintenance is imminent, a wake-up command can be sent via the narrowband network to control the surge arrester monitoring device 200 to switch from a shallow sleep state to a wake-up state.

[0040] In shallow sleep mode, although it consumes slightly more power than in deep sleep mode, it has an extremely fast response speed and can quickly switch to wake-up mode to perform monitoring tasks during power outage maintenance.

[0041] If, within a preset response time after sending the state switching command, the control system 100 does not receive a response signal from the narrowband module 210 based on the message queue telemetry transmission protocol, it indicates that the narrowband module 210 may not have received the state switching command, and the state switching of the surge arrester monitoring device 200 is determined to have failed. At this point, the process returns to the step of sending the state switching command to the narrowband module 210 via the narrowband network based on the message queue telemetry transmission protocol, and the state switching command is resent. This process is repeated until, within the preset response time after sending the state switching command, the control system 100 receives a response signal from the narrowband module 210 based on the message queue telemetry transmission protocol.

[0042] The preset response time can be set according to the actual application. For example, the narrowband module 210 may be delayed for 24 hours in responding to the status switching command, so the preset response time can be set to 24 hours.

[0043] Please see Figure 2 and Figure 4 In some embodiments, there are multiple surge arrester monitoring devices 200. A wake-up command is sent via a narrowband network to control the surge arrester monitoring devices 200 to switch from a shallow sleep state to a wake-up state (i.e., 020), including: 022: Wake-up commands are sent cyclically to multiple surge arrester monitoring devices 200 via a narrowband network. The wake-up commands are used to switch the broadband module 220 from an unconnected state to a long-connected state, so as to control the multiple surge arrester monitoring devices 200 to switch from a shallow sleep state to a wake-up state. 023: Receive heartbeat signals sent by multiple surge arrester monitoring devices 200 through a broadband network to determine the wake-up status of the multiple surge arrester monitoring devices 200; Control methods also include: 040: When multiple surge arrester monitoring devices 200 are successfully woken up, monitoring parameters are sent to the multiple surge arrester monitoring devices 200 so that the multiple surge arrester monitoring devices 200 can perform monitoring tasks and collect monitoring data.

[0044] Specifically, in the shallow sleep state, the narrowband module 210 is in a long-connected state, while the broadband module 220 is not connected. Therefore, the wake-up command must be transmitted through the narrowband network. The wake-up command can also be sent based on the message queue telemetry transmission protocol. There are multiple surge arrester monitoring devices 200 that need to be woken up, and all of them form a wake-up queue.

[0045] Due to various issues during command transmission, sending a single wake-up command may not be sufficient to successfully wake up all surge arrester monitoring devices 200. Therefore, a cyclical sending mechanism was designed. Wake-up commands are cyclically sent to the narrowband modules 210 of multiple surge arrester monitoring devices 200 via a narrowband network. Upon receiving a wake-up command, the narrowband module 210 within the surge arrester monitoring device 200 controls the corresponding broadband module 220 to switch from an unconnected state to a long-connected state, thus switching the surge arrester monitoring device 200 from a shallow sleep state to a wake-up state.

[0046] During the cyclic sending of wake-up commands, after the broadband module 220 of the surge arrester monitoring device 200 switches to a long-connection state, it can send a heartbeat signal through the broadband network. Upon receiving the heartbeat signal, the control system 100 can determine that the corresponding surge arrester monitoring device 200 has been successfully woken up.

[0047] It is understandable that, due to the time difference between the wake-up of the narrowband module 210 and the wake-up of the broadband module 220, the wake-up is considered successful only after the surge arrester monitoring device 200 sends a heartbeat signal through the broadband network. The heartbeat signal indicates that the surge arrester monitoring device 200 is still online, and when the surge arrester monitoring device 200 is in the wake-up state, the heartbeat signal can be continuously sent to the control system 100.

[0048] Once a surge arrester monitoring device 200 is successfully woken up, it can be removed from the wake-up queue and wake-up commands can be sent to the remaining surge arrester monitoring devices 200 in a loop until all surge arrester monitoring devices 200 are woken up.

[0049] When multiple surge arrester monitoring devices 200 are successfully woken up, the user can input the command to send monitoring parameters on the interactive interface to notify the communication module. This will send the monitoring parameters to the multiple surge arrester monitoring devices 200. The sending of monitoring parameters can also be based on a message queue telemetry transmission protocol. Monitoring parameters include standby time, task parameters, task start time, and task duration. The multiple surge arrester monitoring devices 200 can then execute corresponding monitoring tasks and collect monitoring data based on the monitoring parameters.

[0050] In some embodiments, after receiving heartbeat signals transmitted by multiple surge arrester monitoring devices 200 via a broadband network to determine the wake-up status of the multiple surge arrester monitoring devices 200, the control method further includes: A reply signal is sent to multiple surge arrester monitoring devices 200 via a broadband network to keep the multiple surge arrester monitoring devices 200 in an awake state.

[0051] Specifically, after the control system 100 receives the heartbeat signal sent by the surge arrester monitoring device 200 via the broadband network, it needs to respond, that is, send a response signal to the corresponding surge arrester monitoring device 200 via the broadband network. Upon receiving the response signal, the surge arrester monitoring device 200 will remain in an active state.

[0052] If the surge arrester monitoring device 200 sends a preset number of heartbeat signals and does not receive a reply signal, it indicates that the control system 100 or the broadband network may be malfunctioning. In this case, the surge arrester monitoring device 200 can switch to a shallow sleep state or a deep sleep state to reduce power consumption.

[0053] Please see Figure 2 and Figure 5 In some embodiments, the control system 100 is provided with multiple communication ports corresponding to multiple surge arrester monitoring devices 200. After sending a wake-up command via a narrowband network to switch the surge arrester monitoring device 200 from a shallow sleep state to a wake-up state (i.e., 020), the control method further includes: 050: Receives monitoring data reported by multiple surge arrester monitoring devices 200 via broadband network through multiple communication ports based on User Datagram Protocol.

[0054] Specifically, after the surge arrester monitoring device 200 acquires monitoring data, it can send a reporting signal to the control system 100. When the control system 100 needs to acquire monitoring data, it can schedule the monitoring data in the surge arrester monitoring device 200. Since multiple surge arrester monitoring devices 200 can monitor the surge arrester simultaneously and may report monitoring data simultaneously, the control system 100 is equipped with multiple communication ports, using User Datagram Protocol (UDP) for communication. The control system 100 can monitor multiple communication ports.

[0055] Each communication port is connected to a corresponding surge arrester monitoring device 200, so that the control system 100 can receive monitoring data reported by the surge arrester monitoring device 200 via a broadband network through multiple communication ports based on the User Datagram Protocol (UDP). After receiving the monitoring data, the control system 100 can organize the monitoring data to study the causes and patterns of current occurrence, and can also visualize the monitoring data for easier understanding and analysis.

[0056] In practical applications, network conditions may be unstable due to on-site environmental conditions. Using User Datagram Protocol (UDP) communication can prioritize the real-time performance and smoothness of communication.

[0057] In this embodiment, information transmitted via broadband and narrowband is strictly separated. Big data uploads are allocated only to broadband transmission to improve transmission rate, while state switching commands and wake-up commands are allocated only to narrowband transmission to save power for the surge arrester monitoring device 200.

[0058] Please see Figure 2 and Figure 6 In some embodiments, the control system 100 includes a database and a file library. After the surge arrester monitoring device 200 is switched from a shallow sleep state to a wake-up state (i.e., 020) by sending a wake-up command via a narrowband network, the control method further includes: 060: After receiving the monitoring data reported by the surge arrester monitoring device 200 through the broadband network, the monitoring data is processed to determine the key data corresponding to the monitoring data. The key data includes any one or more of the extreme values, average values, and variances of the monitoring data. 070: Store key data in the database and convert monitoring data into monitoring files and save them to the file library.

[0059] Specifically, the control system 100 includes a database and a file library. The network protocols (Internet Protocol, IP) and corresponding communication ports of multiple surge arrester monitoring devices 200 can be stored in the database. When controlling the surge arrester monitoring device 200 to switch states or send monitoring parameters on the interactive interface, the communication module is notified to send the corresponding command through the message queue telemetry transmission protocol. The status of the surge arrester monitoring device 200 in the database is set to "state switching". After receiving the response from the surge arrester monitoring device 200 after processing the command upon receiving it online, the status of the surge arrester monitoring device 200 in the database is then modified according to the status of the response.

[0060] After receiving monitoring data reported by the surge arrester monitoring device 200 via a broadband network, the control system 100 finds that the large volume and numerous monitoring points make direct storage in the database time-consuming. Therefore, the received monitoring data can be saved as a file and processed by a data processing thread. This thread calculates the extreme values, average values, variance, and current values ​​at each time point. The calculated data is stored as key data in the database, while the complete monitoring data is converted into monitoring files and saved to a file library. This achieves efficient data storage.

[0061] Please see Figure 2 In some implementations, the monitoring data includes multiple data packets. After receiving monitoring data (i.e., 050) reported by multiple surge arrester monitoring devices 200 via a broadband network through multiple communication ports based on the User Datagram Protocol, the control method further includes: After receiving the transmission completion signal sent by the surge arrester monitoring device 200 through the broadband network, the packet number of multiple data packets is checked to determine whether there is any packet loss. In the event of packet loss, the surge arrester monitoring device 200 is controlled to re-report the lost data packets via the broadband network based on the packet number of the lost data packets.

[0062] Specifically, due to the large volume of monitoring data, the monitoring data can be divided into multiple data packets for reporting. The control system 100 receives multiple data packets and can save the multiple data packets and their corresponding packet numbers. When the monitoring data reporting is completed, the surge arrester monitoring device 200 can send a transmission completion signal through the broadband network. After receiving the transmission completion signal, the control system 100 checks the packet numbers of the received multiple data packets to determine if there is any packet loss.

[0063] In the event of packet loss, a retransmission command is sent to the surge arrester monitoring device 200 based on the packet number of the lost data packet, controlling the surge arrester monitoring device 200 to re-report the lost data packet through the broadband network.

[0064] Please see Figure 2 and Figure 7 This application also provides a control device 300 applied to a control system 100. The control system 100 is connected to a narrowband module 210 of a surge arrester monitoring device 200 via a narrowband network and to a broadband module 220 of the surge arrester monitoring device 200 via a broadband network. The control device 300 includes a first control module 310, a second control module 320, and a third control module 330. The first control module 310 is used to send a state switching command via the narrowband network to control the surge arrester monitoring device 200 to switch from a deep sleep state to a shallow sleep state. The second control module 320 is used to send a wake-up command via the narrowband network to control the surge arrester monitoring device 200 to switch from a shallow sleep state to a wake-up state. The third control module 330 is used to control the surge arrester monitoring device 200 to switch from a wake-up state to a deep sleep state after receiving monitoring data reported by the surge arrester monitoring device 200 via the broadband network. In deep sleep mode, the narrowband module 210 operates in a timed connection state; in shallow sleep mode, the narrowband module 210 operates in a long connection state; and in wake-up mode, the broadband module 220 operates in a long connection state.

[0065] In some implementations, the first control module 310 is specifically used to send a state switching command to the narrowband module 210 via a narrowband network based on a message queue telemetry transmission protocol. The state switching command is used to switch the narrowband module 210 from a timed connection state to a long connection state, thereby controlling the surge arrester monitoring device 200 to switch from a deep sleep state to a shallow sleep state. The first control module 320 is specifically used to send a wake-up command via the narrowband network when the surge arrester monitoring device 200's state switching is successful, thereby controlling the surge arrester monitoring device 200 to switch from a shallow sleep state to a wake-up state.

[0066] In some implementations, the first control module 310 is specifically used to determine that the state switch of the surge arrester monitoring device 200 is successful if a response signal is received within a preset response time for sending the state switch command; and to determine that the state switch of the surge arrester monitoring device 200 fails if no response signal is received within the preset response time for sending the state switch command, and return to the step of sending the state switch command to the narrowband module 210 through the narrowband network based on the message queue telemetry transmission protocol.

[0067] Please see Figure 2 and Figure 8In some embodiments, there are multiple surge arrester monitoring devices 200. The second control module 320 is specifically used to cyclically send wake-up commands to the surge arrester monitoring devices 200 via a narrowband network. These wake-up commands cause the broadband module 220 to switch from an unconnected state to a long-connected state, thereby controlling the surge arrester monitoring devices 200 to switch from a shallow sleep state to a wake-up state. The control module 300 also receives heartbeat signals sent by the surge arrester monitoring devices 200 via the broadband network to determine the wake-up status of the surge arrester monitoring devices 200. The control device 300 further includes a parameter sending module 340, which, upon successful wake-up of the surge arrester monitoring devices 200, sends monitoring parameters to the surge arrester monitoring devices 200 to enable them to perform monitoring tasks and collect monitoring data.

[0068] In some embodiments, the control device 300 further includes a data receiving module 350. The control system 100 is provided with multiple communication ports corresponding to the multiple surge arrester monitoring devices 200. After sending a wake-up command via a narrowband network to switch the surge arrester monitoring device 200 from a shallow sleep state to a wake-up state, the data receiving module 350 is used to receive monitoring data reported by the surge arrester monitoring device 200 via the broadband network through the multiple communication ports based on the User Datagram Protocol (UDP).

[0069] In some embodiments, the control device 300 further includes a data processing module 360, and the control system 100 includes a database and a file library. After sending a wake-up command via a narrowband network to switch the surge arrester monitoring device 200 from a shallow sleep state to a wake-up state, the data processing module 360 ​​processes the monitoring data received from the surge arrester monitoring device 200 via a broadband network, determines the key data corresponding to the monitoring data, and the key data includes any one or more of the extreme values, average values, and variances of the monitoring data; stores the key data in the database, and converts the monitoring data into monitoring files and saves them to the file library.
