[0044] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0045] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0046] A ground wire is a wire used in power systems and electrical equipment to connect the housing of an equipment or circuit to the earth. In power systems, ground wires help protect equipment from overcurrent and voltage fluctuations. By providing a path for fault current to be discharged, ground wires can prevent equipment from being damaged. When a fault occurs in the equipment (such as insulation damage), the ground wire can conduct the leakage current to the earth, thereby preventing people from touching live parts.

[0047] However, in actual applications, grounding wires are highly dependent on manual labor and have delayed status monitoring. In some cases, it is necessary to confirm the current status of the grounding wire before continuing the power operation based on the status of the grounding wire. If manual on-site verification is performed, it will not only be time-consuming and laborious, but may also result in errors and omissions.

[0048] The inventor proposed a technical concept that can deploy sensors and other equipment on the grounding wire to monitor in real time whether the grounding wire is in a hooked state, and summarize the status of the grounding wire that needs to be confirmed to the power control system through transmission between devices, so as to deploy the next task according to the status of the grounding wire.

[0049] However, some lines are complex in design, and it is difficult to efficiently sense and report the grounding wire status. For example, in a three-phase system (taking phases A, B, and C as an example), not only is it necessary to set a corresponding device on each of the three phases of the grounding wire to sense the grounding wire status, but it is also necessary to set an additional positioning device around the insulating operating rod. This positioning device can play a role in locating the grounding wire and summarizing the grounding wire status of the three phases, but how the positioning device can summarize the grounding wire status of each phase in a timely manner is a major problem. The inventor took into account the scenario where the grounding wire may be deployed outdoors, and connected each phase sensing device to the positioning device through a wire to transmit information such as the grounding wire status to the positioning device, but this requires three wires to be drawn from the positioning device to connect to the monitoring device at the grounding wire end. The additional connection may interfere with the original lines such as the grounding wire and the connection between the power equipment. If the original lines are relatively dense, the newly added connections are likely to cause safety risks.

[0050] The inventor therefore thought of configuring Bluetooth modules on the positioning device and the devices that monitor the grounding wires of each phase, so that the positioning device can obtain the status of the grounding wire from the device that monitors the grounding wire through Bluetooth. By configuring the relevant equipment in advance in this way, the real-time monitoring and reporting of the grounding wire status can be achieved without the need for the staff to connect the communication wires, so that the grounding wire status can be confirmed in time, improving work efficiency and reducing safety risks.

[0051] Based on this, the present application proposes a ground wire status detection method, device, equipment, storage medium and program product.

[0052] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0053] Figure 1 A schematic diagram of a grounding wire status detection method provided in this application Figure 1 ,like Figure 1As shown, the method includes:

[0054] Step S101, obtaining a device identification of a positioning monitor, and associating the positioning monitor with a ground wire to be tested according to the device identification.

[0055] The ground wire status detection method provided in the embodiment of the present application can be applied to a ground wire monitoring device, which includes a positioning monitor and a hooking status monitor.

[0056] The ground wire monitoring device can be applied to the monitoring of one or a group of ground wires. The positioning monitor can include a positioning module, a battery, a Bluetooth module, etc. The hooking status monitor can include a sensor, a battery, a Bluetooth module, etc. The sensor can be used to sense the hooking status of the ground wire.

[0057] Optionally, the hook-up status monitor can be installed at the conductor clamp of the ground wire, and the positioning monitor can be installed at the insulating operating rod.

[0058] Optionally, the battery module is a detachable structure so that the battery can be replaced when the battery of the positioning monitor and the hooking status monitor is low.

[0059] Step S102, setting a hooking state monitor to monitor the hooking state of the ground wire to be tested, and performing hooking and unhooking operations on the ground wire to be tested.

[0060] Step S103, controlling the positioning monitor to obtain the status detection information of the ground wire to be tested from the hooked status monitor via Bluetooth.

[0061] Step S104, transmitting the status detection information to the power control system.

[0062] In an embodiment of the present application, the unique identity of the positioning monitor can be confirmed in advance through the device identifier of the positioning monitor, and it can be associated with a grounding wire to be monitored in a background system, so that the system can identify the actual grounding wire corresponding to the received grounding wire status based on the association between the positioning monitor and the grounding wire.

[0063] The working principle of the ground wire status detection method in the embodiment of the present application is explained below with reference to a specific example.

[0064] Figure 2 A schematic diagram of an interactive timing involved in a ground wire status detection method provided in the present application.

[0065] For example, Figure 2As shown, first, the terminal device can be a smart phone, etc., which can send the scheduling operation to the terminal device used by relevant personnel, and determine the grounding wire involved and the grounding wire monitoring device used (including the positioning monitor and the hanging status monitor) according to the scheduling operation. By scanning the QR code and other identifications on the positioning monitor, its unique identity (such as the device ID of the positioning monitor) can be confirmed and associated with the grounding wire and synchronized to the system.

[0066] Secondly, after the equipment association is completed, the operator can hang or remove the grounding wire on site. After the hanging status monitor equipped at the grounding wire end senses the change in the state of the grounding wire (such as the grounding wire becomes hung state or becomes removed state), the hanging status monitor will first feedback the state of the grounding wire to the positioning monitor via Bluetooth, and the positioning monitor will summarize and report it to the power control system.

[0067] Finally, the power control system can display and process the grounding wire status reported by the underlying positioning monitor. If an abnormality occurs, it can also prompt relevant personnel to handle the abnormality.

[0068] In some possible implementations, the information reported by the positioning monitor may include, in addition to the ground wire status (attached or removed), positioning information (latitude, longitude, altitude, etc.), identity information such as the device ID of the positioning monitor, and the power level of the positioning monitor and the attachment status monitor.

[0069] In the above embodiment, the identity of the grounding wire can be identified by obtaining the device identification of the positioning monitor and associating it with the grounding wire, setting a hooking state monitor to monitor the hooking state of the grounding wire to be tested and performing hooking and disassembly operations on the grounding wire to be tested, and then controlling the positioning monitor to obtain the grounding wire status information from the hooking state monitor via Bluetooth and transmit it to the power control system. The hooking state monitor can sense the state changes of the grounding wire in real time, and the hooking state monitor and the positioning monitor can communicate via pre-configured Bluetooth without adding additional wires, which can reduce line safety risks, confirm the hooking state of the grounding wire in real time, and improve work efficiency.

[0070] Based on the usage scenario of the grounding wire, the hanging status monitor is installed at the conductor clamp of the grounding wire. In some cases, in order to ensure the three-phase hanging status detection, hanging status monitors need to be installed on phases A, B, and C, and the ground wire positioning monitor is installed at the insulating operating rod, so only one needs to be installed.

[0071] According to the inventive concept of this application, the hook-up status monitor and the positioning monitor can communicate via Bluetooth, but the Bluetooth device will occupy the resources of the Bluetooth chip when establishing a connection with other devices, and can generally only communicate with one device. Based on this, this application proposes a multi-point Bluetooth communication solution to achieve multi-way communication.

[0072] Figure 3 This is a schematic diagram of Bluetooth communication provided as an example in this application. Figure 3 As shown, the positioning monitor can be set to the master device mode, and multiple hooking status monitors can be set to the slave device mode. In this way, the positioning monitor can realize multi-channel communication with multiple hooking status monitors to meet the application requirements of the grounding wire monitoring device.

[0073] In one embodiment, the ground wire to be tested includes a plurality of ground wires corresponding to different phases, the positioning monitor has a built-in Bluetooth master controller, and the hook-up status monitor has a built-in Bluetooth slave controller;

[0074] The positioning monitor is configured to simultaneously establish independent Bluetooth connections with multiple hooking status monitors that monitor different phase grounding lines through a Bluetooth main controller, and obtain the hooking status of the corresponding phase grounding line from the hooking status monitor through the Bluetooth connection.

[0075] Exemplarily, the positioning monitor with a built-in Bluetooth master controller is the master device, and the attachment status monitor with a built-in Bluetooth slave controller is the slave device. The master device initiates pairing requests with each slave device in turn through time-division multiplexing to establish an independent point-to-point Bluetooth link. Each link is assigned an independent communication channel (Channel) or logical link identifier to ensure data isolation. Each slave device transmits the attachment status of its corresponding phase (such as attached or not attached) to the master device through a dedicated GATT (full name Generic Attribute Profile) service. Each slave device can enter a low-power mode during non-communication periods to save energy.

[0076] The master device adopts an event-driven mechanism (such as interrupt response) or a polling scheduling algorithm to ensure priority processing when the ground line status is updated.

[0077] In the above embodiment, the multi-connection management capability of the master device is used to realize physical layer time-sharing processing and logical simultaneous communication, and the sleep mode of the slave device during the idle period can adapt to the monitoring scenario with limited power, so that the present application scheme has the characteristics of concurrency and low power consumption. In addition, the independent communication link between the positioning monitor and the hook status monitor can avoid data conflicts and ensure the reliability of ground wire status transmission.

[0078] In one embodiment, the hooking state monitor is configured to: in response to detecting that the hooking and removing operation is completed, sense the hooking state of the ground wire to be tested; send the hooking state to a preset Bluetooth broadcast channel;

[0079] The positioning monitor is configured to: periodically scan the Bluetooth broadcast channel, parse the scanned broadcast packets, and generate status detection information according to the parsing results.

[0080] For example, if the operator performs a hooking or removal operation on the ground wire, the corresponding hooking status monitor can send the address and status information to the preset Bluetooth broadcast channel through a periodic broadcast packet after sensing the change in the ground wire state. The positioning monitor scans the Bluetooth broadcast channel, receives the broadcast data packet, and performs subsequent operations based on the information in the packet, such as integrating the ground wire hooking state into status detection information and whether to report to the power control system.

[0081] In the above embodiments, a multi-point Bluetooth communication solution is proposed for the situation in which the positioning monitor and the hanging status monitor are deployed on the same line or the same group of ground wires in actual application scenarios and are close to each other. The solution has the advantages of low power consumption, strong real-time performance, and no need for connection, and is suitable for scenarios with high response time requirements.

[0082] In one embodiment, Figure 4 As shown, transmitting the status detection information to the power control system may include:

[0083] Step S401, obtaining an interactive topic set based on the message queue telemetry transmission protocol MQTT.

[0084] Among them, MQTT (Message Queuing Telemetry Transport) is a message protocol based on the publish-subscribe model.

[0085] Step S402: Generate a data packet according to the device identification and the status detection information and publish it to the interactive topic, so that the power control system subscribing to the interactive topic can obtain the status detection information by parsing the data packet.

[0086] Figure 5 A schematic diagram of a message queue telemetry transmission protocol application provided for this application.

[0087] like Figure 5 As shown, the power control system can create products and devices as the platform domain of MQTT. The created device is a grounding wire monitoring device, and an interactive topic is set for communicating with the device at the grounding wire end.

[0088] For example, the interactive theme settings can refer to the following table:

[0089] equipment theme Function Ground wire monitoring device / iot / {deviceId} / {deviceType} / device / data Positioning monitor information upload Ground wire monitoring device / iot / {deviceId} / {deviceType} / device / reply Positioning monitor information response

[0090] The information sent through the interactive topic may include device identification, device ID, longitude and latitude of positioning information, ground wire attachment status, power level of the attachment status monitor, and power level of the positioning monitor.

[0091] In some possible implementations, the method further includes: setting a will message through the MQTT agent, and when a network abnormality or a client abnormality occurs in the positioning monitor, automatically publishing the will message to the interactive topic, and the will message is used to notify the power control system that the positioning monitor is in a communication interruption state.

[0092] The grounding wire monitoring device is used in conjunction with the system through 4G in a distribution network environment, and the network condition cannot be reliably guaranteed. In response to this situation, the positioning monitor can preset the Last Will message parameters, including the Will Topic and the Will Message, when establishing a connection with the MQTT proxy server. When the positioning monitor is abnormally disconnected due to network anomalies or client failures, the MQTT proxy server automatically publishes the Will message to the preset Will topic. The power control system can learn from the corresponding topic that the positioning monitor is disconnected, and take measures such as restarting the device or notifying relevant personnel to investigate, reduce the impact of network factors, and try to avoid communication failures due to network or client anomalies.

[0093] In the above embodiment, by adopting a message protocol in a publish-subscribe mode, one-to-many message publishing can be provided, and application coupling can be released, so that the communication between multiple grounding wire monitoring devices and a single server running the power control system can be satisfied. In addition, a small transmission method such as MQTT is adopted, which has lower overhead, which is in line with the situation that the grounding wire monitoring device is based on 4G transmission and is mostly used outdoors, thereby reducing network traffic.

[0094] In one embodiment, generating a data packet according to the device identification and the status detection information and publishing the data packet to the interaction topic may include:

[0095] An encryption chip is used to perform link encryption on the network transmission layer of the data packet to generate a session key; a preset encryption algorithm is used to perform group encryption on the plaintext data in the data packet to generate ciphertext data; the session key, the ciphertext data and the algorithm parameters are packaged in the format of the interactive topic and then published.

[0096] The encryption algorithm may be SM4 algorithm, which is a block encryption algorithm.

[0097] In the embodiment of the present application, the ground wire monitoring device transmits data with the background power control system, and the transmission content includes but is not limited to the ground wire connection status, ground wire positioning information, timestamp, equipment identification information, etc. In order to ensure the confidentiality, integrity and non-tamperability of the data transmission of the ground wire monitoring device and ensure the security of the data during transmission, a hierarchical structure can be used for encryption, which can specifically include two levels: hardware and software. The hardware part can use a dedicated encryption chip and network interface, and the software part is responsible for the relevant algorithms for data encryption and decryption.

[0098] Exemplarily, the SM4 national encryption algorithm can be used at the software level to encrypt data content, specifically including: generating an extended key based on a preset key, performing 32 rounds of iterative operations through the key extension module of the SM4 algorithm to generate a round key; inputting the data to be encrypted into the SM4 basic round function in 128-bit groups, performing 32 rounds of nonlinear transformation and obfuscation operations in combination with the round key to generate ciphertext data; transmitting the encrypted ciphertext data to the background system through the MQTT protocol, carrying the hardware encryption identifier and the SM4 algorithm version number for decryption verification during transmission.

[0099] In one embodiment, a specific design scheme of a grounding wire monitoring device is provided in combination with the application scenario of the grounding wire monitoring device. Considering certain specific limitations such as safety insulation distance, equipment installation time, usage scenario, fixing method, etc., the terminal using electricity mainly uses batteries as the power supply, and the grounding wire monitoring device of the present application is powered by batteries.

[0100] With the same amount of power, the terminal can work longer with a low-power design and is more suitable for grounding wire application scenarios. Whether from a cost perspective or a product performance perspective, it is essential to reduce power consumption for grounding wire monitoring devices.

[0101] Figure 6 The schematic diagram of the structure of a positioning monitor provided as an example in this application, wherein GNSS (Global Navigation Satellite System) is a global satellite navigation system, and the Beidou navigation system can be selected.

[0102] For example, to achieve low power consumption design, the following technical means can be used to achieve this goal:

[0103] a. Select a high-efficiency DC / DC power supply circuit and equip it with a suitable filter circuit to achieve high efficiency and low power ripple and improve the efficiency of electric energy utilization;

[0104] b. Considering both chip price and low power consumption, choose low power consumption chips and circuit designs to reduce power consumption from the device link;

[0105] c. Choose an MCU chip with appropriate computing power, strong anti-interference ability, and low power consumption as the main control. Under the premise of taking into account the response speed, set the appropriate main frequency and try to reduce the main frequency. Try to turn off the circuit parts of the MCU that are not used temporarily to reduce the power consumption of the MCU;

[0106] d. Set reasonable sleep and wake-up time intervals and methods for MCU to reduce MCU power consumption;

[0107] e. Determine various detailed technical solutions and implement them into product design, refine hardware design and embedded software design, and obtain the optimal low-power solution and low-power product design.

[0108] Based on the above technical means, from the current MCU model, the ground wire positioning monitor of the ground wire monitoring device can choose the STM32L431 ultra-low power microcontroller, which is based on the high-performance Arm ® Cortex ® -M4 32-bit RISC core ultra-low power microcontroller, operating frequency up to 80 MHz, designed to meet the functional performance requirements of this solution. The hardware composition includes MCU and its peripheral systems, Bluetooth communication module, 4G communication module, encryption module, audio module, vibration sensor, indicator light, power control, watchdog, debug serial port, debug JTAG, etc.
