[0098] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of the present application, and cannot be understood as limiting the embodiments of the present application.

[0099] In the related art, the Global Positioning System (GPS) and / or Beidou positioning modules are usually used to provide accurate location information. These systems determine the exact location of the device by receiving signals from satellites. However, these systems may not be able to provide accurate positioning information indoors or in obstructed environments. In order to improve the accuracy and efficiency of positioning, auxiliary technologies such as infrared technology, ultra-wideband (UWB) technology and / or visible light cameras are often introduced to enhance positioning.

[0100] Infrared technology can determine the location of an object by detecting infrared signals and is suitable for short-distance positioning. Ultra-wideband technology measures distance by sending and receiving extremely short pulse signals, thereby achieving high-precision indoor positioning. Visible light cameras can identify and locate objects through image recognition technology.

[0101] However, the introduction of these technologies also brings additional challenges. First, the cost of the equipment will increase because more sensors and communication modules need to be integrated. Second, the complexity of installing and deploying these devices will also increase, requiring more expertise and time. In addition, these devices will also require regular maintenance and calibration to ensure their accuracy and reliability.

[0102] Based on the above questions, please refer to Figure 1 An embodiment of the present application provides a communication module, which includes a first wireless communication chip and a second wireless communication chip, wherein the communication protocols of the first wireless communication chip and the second wireless communication chip are different.

[0103] The first wireless communication chip can scan the location to obtain the first neighbor node information table.

[0104] The second wireless communication chip can scan the location to obtain a second neighbor node information table.

[0105] The communication module can upload the first communication module identification code, the location of the communication module, the first neighbor node information table and the second neighbor node information table of the communication module to the operation and maintenance platform that is communicatively connected to the communication module. The operation and maintenance platform generates a positioning heat map according to the first communication module identification code, the location of the communication module, the first neighbor node information table and the second neighbor node information table, and constructs a positioning library according to the positioning heat map to locate the communication module according to the positioning library.

[0106] Specifically, the communication module refers to a module that integrates the first wireless communication chip and the second wireless communication chip to achieve the coexistence of two wireless communication technologies. In addition, the communication module can support the national encryption SM01-09 algorithm through a built-in power-specific encryption chip (i.e., the security chip mentioned later) to ensure communication security.

[0107] The first wireless communication chip refers to the wireless communication chip in the communication module, which supports the Bluetooth protocol and is responsible for realizing the wireless communication function of the module. It is suitable for short-distance communication and connection between devices. The first wireless communication chip supports the latest Bluetooth 6.0 standard and has functions such as high-precision distance measurement, secure communication, and collaboration with the second wireless communication chip.

[0108] High-precision distance measurement is achieved through Bluetooth channel sounding (BCS) and master-slave ranging mode. Channel sounding (BCS) is a technology introduced by Bluetooth 6.0 that can achieve high-precision distance measurement. It calculates the distance between two devices by analyzing the attenuation of the signal during transmission between them. The master-slave ranging mode refers to measuring the distance of a third node through a relay node. This means that even if the target device is out of the coverage range of the second wireless communication chip, it can still be located through the BLE signal.

[0109] Secure communication is achieved through SM04 hardware encryption and decryption and power-specific encryption chips. SM04 hardware encryption and decryption refers to the SM04 hardware encryption and decryption function that supports the use of security chips to ensure the security of communications. The power-specific encryption chip refers to the integration of the first wireless communication chip and the power-specific encryption chip, which supports the national secret SM01-09 algorithm, has a built-in chip ID, can be used for entity security identification, and supports cryptographic service management platform identity authentication and digital certificate storage. The national secret SM01-09 algorithm refers to a series of cryptographic standards designed to ensure the security of commercial cryptography, including SM1 (SCB2), SM2, SM3, SM4, SM7, SM9 and Zu Chongzhi Cryptography Algorithm (ZUC), which are widely used in various fields.

[0110] Collaboration with the second wireless communication chip means that the first wireless communication chip and the second wireless communication chip coexist in the communication module without interfering with each other. In addition, the first wireless communication chip supports the master-slave mode and can be used as both a server and a client to achieve a flexible communication method. In addition, when the second wireless communication chip is in sleep mode, the second wireless communication chip can be awakened by the first wireless communication chip.

[0111] The second wireless communication chip refers to the wireless communication chip in the communication module, which supports the WiFi protocol and is responsible for realizing the wireless communication function of the module, and can realize the positioning and network security access of the communication module. The second wireless communication chip has the functions of communication positioning, secure communication and collaboration with the first wireless communication chip.

[0112] Communication positioning refers to scanning the surrounding WiFi signals to obtain the MAC address, signal strength and other information of the WiFi access point / router, and combining it with the geographic location information to achieve device positioning. In addition, the second wireless communication chip can access the power-specific WAPI wireless LAN for network security access, replacing Ethernet / optical fiber / 4G / 5G, saving traffic fees or facilitating deployment and implementation.

[0113] Secure communication refers to the integration of the second wireless communication chip and the power-specific encryption chip, which supports the national encryption SM01-09 algorithm, has a built-in chip ID for body security identification, and supports identity authentication and digital certificate storage for the cryptographic service management platform. In addition, it supports hardware acceleration and is not limited by the performance of the security chip SM04 encryption and decryption algorithm and the communication interface performance, ensuring communication efficiency.

[0114] The first neighbor node information table refers to information generated by the first wireless communication chip, including relevant information of the first neighbor node scanned by the communication module at its location. The first neighbor node refers to other devices or nodes based on the Bluetooth protocol that are directly connected to the communication module in a wireless network or can communicate with each other, such as base stations, routers, other communication devices, etc. The first neighbor node information table includes a node identifier (i.e., the first communication module identification code), signal strength, network information, and other parameter information. The node identifier is a unique identifier for each neighbor node, such as a device MAC address. The signal strength is the signal strength between the communication module and the neighbor node, which can be used to estimate the distance between the two. The network information is the network information to which the neighbor node belongs. Other parameter information refers to other relevant information such as timestamps, node types (such as base stations, routers, etc.), and node status.

[0115] The second neighbor node information table refers to information generated by the second wireless communication chip, including relevant information of the second neighbor node scanned by the communication module at its location. The second neighbor node refers to other devices or nodes based on the WiFi protocol that are directly connected to the communication module in a wireless network or can communicate with each other, such as base stations, routers, other communication devices, etc. The second neighbor node information table includes node identification, signal strength, network information and other parameter information. The node identification is a unique identifier for each neighbor node. The signal strength is the signal strength between the communication module and the neighbor node, which can be used to estimate the distance between the two. The network information is the network information to which the neighbor node belongs, such as SSID. Other parameter information refers to other relevant information such as timestamp, node type (such as base station, router, etc.), node status, etc.

[0116] Positioning heat map refers to a visualization tool used to display the wireless signal distribution or device distribution in the area where the communication module is located, thereby helping to achieve more accurate positioning.

[0117] First, the first wireless communication chip scans the surrounding environment and obtains the surrounding BLE device information (i.e., relevant information of devices communicating based on the Bluetooth protocol), including the device MAC address, signal strength, etc., to form a first neighbor node information table. At the same time, the second wireless communication chip scans the surrounding environment and obtains the surrounding WiFi device information (i.e., relevant information of devices communicating based on the WiFi protocol), including the device MAC address, signal strength, etc., to form a second neighbor node information table.

[0118] Next, the communication module uploads its own identification code, location information, and the "first neighbor node information table" and "second neighbor node information table" to the operation and maintenance platform.

[0119] Then, the operation and maintenance platform generates a positioning heat map based on the uploaded information and builds a positioning library. The positioning heat map reflects the distribution of WiFi and BLE devices in the surrounding environment and can be used as a positioning reference. The positioning library records the location information of the communication module and the surrounding neighbor node information for subsequent positioning.

[0120] Finally, the communication module scans the surrounding environment again to obtain the latest neighbor node information. The operation and maintenance platform matches the latest neighbor node information with the positioning library, and generates the coordinate position with the highest probability based on the matching results to achieve positioning.

[0121] In certain embodiments, see Figure 2 , Figure 2 The figure is a schematic diagram of the operation status of the communication module. Among them, the communication module processes wired and wireless communication port requests, and distinguishes between northbound wired interfaces and wireless connection channel interfaces according to the communication module connection interface. After receiving a wired connection request, WiFi and Bluetooth (i.e., Bluetooth communication) communications are distinguished according to the communication protocol type, with WiFi corresponding to northbound uplink and Bluetooth corresponding to southbound downlink. A connection channel is established according to the protocol type, and the data communication process begins after the connection is established. If the connection establishment times out, it will be fed back that the current network is unavailable, and the connection request establishment failure will be returned. When a WiFi connection request or a Bluetooth connection request is received, it is determined whether it is a module body communication information request or a relay forwarding requirement based on the request data type.

[0122] In summary, in the communication module of the embodiment of the present application, the communication module includes a first wireless communication chip and a second wireless communication chip, wherein the communication protocols of the first wireless communication chip and the second wireless communication chip are different. The first wireless communication chip is configured to scan the location to obtain a first neighbor node information table. The second wireless communication chip is configured to scan the location to obtain a second neighbor node information table. The communication module is configured to upload the first communication module identification code of the communication module, the location of the communication module, the first neighbor node information table and the second neighbor node information table to the operation and maintenance platform connected to the communication module communication, and the operation and maintenance platform generates a positioning heat map according to the first communication module identification code, the location of the communication module, the first neighbor node information table and the second neighbor node information table, and constructs a positioning library according to the positioning heat map to locate the communication module according to the positioning library. In this way, the communication module collects the first neighbor node information table and the second neighbor node information table by using two wireless communication chips with different communication protocols and uploads them to the operation and maintenance platform to build a positioning library, which can significantly improve the accuracy and reliability of positioning, expand the positioning coverage, optimize network planning and management, support multi-technology integration, enhance user experience, and reduce maintenance costs, thereby comprehensively improving the performance and efficiency of the communication system.

[0123] In some embodiments, the first wireless communication chip can scan the location to obtain the first wireless name, second communication module identification code and first signal strength of the neighboring node near the location, and construct a first neighboring node information table according to the second communication module identification code and the first signal strength.

[0124] Specifically, the first wireless name refers to the Bluetooth name of the neighbor node, that is, the network information node identifier.

[0125] The second communication module identification code refers to the MAC address of the neighboring node, which is used to uniquely identify the device, that is, the node identification.

[0126] The first signal strength refers to the Bluetooth signal strength of the neighboring node, which is used to evaluate the distance to the node.

[0127] The first wireless communication chip will scan the surrounding environment, find other Bluetooth devices, and obtain the first wireless name, the second communication module identification code and the first signal strength. The other Bluetooth devices scanned are called first neighbor nodes. Then, the chip will construct a first neighbor node information table including the first wireless name, the second communication module identification code and the first signal strength of the first neighbor node based on the scanned information.

[0128] In this way, the first wireless communication chip can construct a first neighbor node information table, which can provide a detailed mapping of the surrounding environment of the communication module for subsequent positioning or other purposes.

[0129] In some embodiments, the second wireless communication chip can scan the location to obtain the second wireless name, second communication module identification code and second signal strength of the neighboring node near the location, and construct a second neighboring node information table based on the second communication module identification code and the second signal strength.

[0130] Specifically, the second wireless name refers to the WiFi name of the neighboring node, that is, network information.

[0131] The second communication module identification code refers to the MAC address of the neighboring node, which is used to uniquely identify the device, that is, the node identification.

[0132] The second signal strength refers to the WiFi signal strength of the neighboring node, which is used to evaluate the distance to the node.

[0133] The first wireless communication chip will scan the surrounding environment, search for other WiFi devices, and obtain the second wireless name, the second communication module identification code, and the second signal strength. The scanned other WiFi devices are called second neighboring nodes. Then, the chip will construct a second neighboring node information table including the first wireless name, the second communication module identification code, and the second signal strength of the second neighboring node based on the scanned information.

[0134] In this way, the second wireless communication chip constructs a second neighbor node information table, which can provide a detailed mapping of the surrounding environment of the communication module for subsequent positioning or other purposes.

[0135] In some embodiments, the communication module can record the first neighbor node information table and the second neighbor node information table based on a preset period, and when the first neighbor node information table and the first neighbor node historical information table are inconsistent, and the second neighbor node information table and the second neighbor node historical information table are inconsistent, the first neighbor node information table and the second neighbor node information table are reported to the operation and maintenance platform.

[0136] Specifically, the communication module can monitor changes in the surrounding network environment by periodically scanning the surrounding devices equipped with the first wireless communication chip and the second wireless communication chip, and recording their MAC addresses and signal strengths. When changes in neighbor node information are detected, that is, when the first neighbor node information table and the first neighbor node historical information table are inconsistent, and the second neighbor node information table and the second neighbor node historical information table are inconsistent, such as when a device is added, a device disappears, or the signal strength changes, it can be determined that the network status has changed, and a network dynamic change event will be generated and reported to the operation and maintenance platform.

[0137] The newly added device event means that when a new device equipped with the first wireless communication chip and the second wireless communication chip is detected, its MAC address and signal strength will be recorded and reported to the operation and maintenance platform.

[0138] The device disappearance event refers to when it is detected that the device equipped with the first wireless communication chip and the second wireless communication chip disappears from the network, its MAC address and signal strength will be recorded and reported to the operation and maintenance platform.

[0139] Signal strength change event means that when the signal strength of the device equipped with the first wireless communication chip and the second wireless communication chip is detected to have changed, its MAC address and signal strength will be recorded and reported to the operation and maintenance platform. For example, if the device equipped with the first wireless communication chip and the second wireless communication chip is moved, the strength and MAC address of its Wi-Fi and Bluetooth signals may change, and thus be recognized by the communication module.

[0140] In this way, changes in the network environment can be automatically monitored and reported to the operation and maintenance platform in a timely manner, which helps to ensure stability and reliability while also improving management efficiency.

[0141] The first wireless communication chip can support Bluetooth channel detection and high-precision distance measurement based on the Bluetooth 6.0 standard.

[0142] Specifically, Bluetooth channel detection high-precision distance measurement based on the Bluetooth 6.0 standard refers to a ranging technology that uses new features in the Bluetooth 6.0 core specification to accurately measure the distance between two Bluetooth devices through phase ranging (Phase-Based Ranging, PBR) or round-trip time (Round-Trip Time, RTT).

[0143] The high-precision distance measurement based on Bluetooth channel detection of the Bluetooth 6.0 standard can achieve higher-precision distance measurement. Compared with traditional Bluetooth positioning technology, the positioning accuracy can be improved to the centimeter level. In addition, by measuring the distance between the surrounding Bluetooth devices, the location information of the device can be obtained to realize the positioning function. In this way, it is possible to sense whether the device equipped with the first wireless communication chip enters or leaves a specific area, such as a safe area, a dangerous area, etc.

[0144] In this way, by supporting channel detection and high-precision distance measurement of the Bluetooth 6.0 standard, the first wireless communication chip can provide more accurate location data, thereby improving the user experience.

[0145] In some embodiments, the communication module also includes a security chip, and the communication module can send a first communication module identification code to the operation and maintenance platform so that the operation and maintenance platform can perform identity authentication processing. Receive verification feedback information issued by the operation and maintenance platform to establish a communication connection with the operation and maintenance platform, wherein, when the operation and maintenance platform receives the first communication module identification code sent by the communication module for the first time, or the communication connection with the communication module is abnormal, the verification feedback information is generated according to the first communication module identification code and the security certificate associated with the first communication module identification code, and the security certificate is generated according to the first communication module identification code. When the first communication module identification code sent by the communication module is not received for the first time and the communication connection with the communication module is normal, the verification feedback information is generated according to the first communication module identification code.

[0146] Specifically, when the operation and maintenance platform receives the first communication module identification code sent by the communication module for the first time, or when an abnormality occurs in the communication connection with the communication module, the communication module sends its unique first communication module identification code to the operation and maintenance platform. Then, the operation and maintenance platform queries the database according to the identification code to confirm the identity of the communication module. Then, the operation and maintenance platform generates a security certificate associated with the communication module according to the identification code. Subsequently, the operation and maintenance platform sends the verification feedback information and the security certificate to the communication module. Finally, the communication module uses the security certificate to establish a secure communication connection with the operation and maintenance platform.

[0147] When the communication module receives the first communication module identification code sent by the communication module for the first time and the communication connection with the communication module is normal, the communication module sends its first communication module identification code to the operation and maintenance platform. Then, the operation and maintenance platform confirms the identity of the communication module based on the first communication module identification code. Subsequently, the operation and maintenance platform sends the verification feedback information to the communication module. Finally, the communication module establishes a secure communication connection with the operation and maintenance platform.

[0148] In this way, the communication module can securely establish a communication connection with the operation and maintenance platform and ensure security throughout the communication process, helping to prevent unauthorized access and data leakage while ensuring the stability and reliability of communication.

[0149] In some implementations, the first wireless communication chip is capable of encrypting or decrypting using a preset encryption algorithm in the security chip.

[0150] Specifically, the security chip refers to a built-in power-specific encryption chip that supports the national encryption SM01-09 algorithm and can provide data encryption, decryption, digital signature, identity authentication and other functions to ensure the security of data during transmission and processing.

[0151] The first wireless communication chip can convert plaintext data into ciphertext data through the security chip through an encryption algorithm to ensure that the data is not stolen or tampered with during transmission. Alternatively, the ciphertext data can be converted into plaintext data through a decryption algorithm to ensure that the data can be correctly interpreted and used.

[0152] In this way, by encrypting and decrypting using the encryption algorithm pre-set in the security chip, the first wireless communication chip can provide stronger data protection measures, help prevent data leakage, unauthorized access and other network security threats, thereby ensuring the confidentiality and integrity of communications.

[0153] In some embodiments, the second wireless communication chip includes an accelerator unit, and the second wireless communication chip can implement accelerated encryption or decryption based on the accelerator unit.

[0154] Specifically, the accelerator unit refers to a hardware module specifically used for data encryption and decryption, which is integrated inside the second wireless communication chip and can increase the speed of encryption and decryption.

[0155] The second wireless communication chip can realize accelerated encryption or decryption based on the accelerator unit. The accelerator unit can realize hardware acceleration and is not limited by the performance of the software algorithm, so it can provide higher performance. By using the accelerator unit, the encryption and decryption speed of the communication chip can be significantly improved, thereby improving the performance of the entire communication system.

[0156] In this way, by integrating the accelerator unit, the second wireless communication chip can provide faster and more secure encryption and decryption processing, thereby ensuring the real-time nature of communication.

[0157] In some implementations, the communication module can perform identification processing based on the encrypted information obtained by the first wireless communication chip to ensure the security of the communication connection with the communication module.

[0158] Specifically, the communication module can receive connection requests from external devices (devices equipped with the communication module), and can identify whether the request is legal based on the protocol type, data format and other information of the connection request. The communication module has a built-in SM04 power-specific encryption algorithm that can encrypt and decrypt the transmitted information. For information that has not been encrypted, the communication module will consider it an unsafe access and refuse to receive the information, thereby effectively distinguishing between unencrypted Bluetooth communication and encrypted Bluetooth communication to prevent malicious attacks. In addition, the communication module will use the SM04 encryption algorithm to encrypt the connection request. Only authorized users or devices with the correct key can decrypt the connection request and establish a connection. This can effectively prevent malicious users or devices from establishing a connection and ensure the security of the communication connection.

[0159] Thus, with this configuration, the communication module is able to provide a higher level of security, ensuring the confidentiality and integrity of data transmission while preventing unauthorized access and potential cyber attacks.

[0160] In some embodiments, the communication module can wake up the second wireless communication chip based on the first wireless communication chip.

[0161] Specifically, in the communication module, the first wireless communication chip is responsible for receiving connection requests from external devices and controlling the entire communication process. When no external device is connected, the second wireless communication chip is in a dormant state to save power consumption. When an external device initiates a connection request through the first wireless communication chip, the first wireless communication chip will wake up the second wireless communication chip and put it into working state to perform operations such as data transmission or positioning.

[0162] See also Figure 3 , Figure 3 The figure is a schematic diagram of the communication module state transition process. The communication module determines whether the current state is idle based on the wired connection port and the wireless air interface. When there is no connection established or there is no data communication for a period of time, the communication state is switched to the sleep state. The standby state starts the periodic network neighbor node status scan. When an external connection is established or internal data needs to be sent out, the standby idle state is switched to the communication state and the periodic scanning work is stopped.

[0163] In certain embodiments, see Figure 4 , Figure 4 Figure 1 is a schematic diagram of the sleep state of the communication module. The communication module performs the network neighbor node scanning process when there is no external device connection and no data communication, that is, during the sleep state. The WiFi and Bluetooth dual-mode scanning work is turned on. The second wireless communication chip scans the APs and routers existing in each channel in turn, records the channel number, MAC address and signal strength, and then the first wireless communication chip starts to scan the MAC addresses and signal strengths of the three public channels, and records the channel number, MAC address and signal strength. The second wireless communication chip and the first wireless communication chip inform each other of the idle and busy states through the status pin. The WiFi and Bluetooth scans do not interfere with each other and use the public spectrum 2.4G resources in a time-division manner. It should be noted that the second wireless communication chip generally starts scanning from the 5GHz frequency band to the 2.4GHz frequency band, and the first wireless communication chip uses the 2.4G frequency band and uses it in staggered time-division. After completing the full-band scan, the communication module compares the historical information with the network information table of the current network neighbor node. When the number of MAC addresses changes by more than a certain value, the current stored network neighbor information table is updated and reported to the operation and maintenance management information platform for this scan record. When the change is small, the periodic scanning process continues. The scanning period can be set and adjusted, supporting local settings and remote parameter delivery.

[0164] Thus, through this configuration, the communication module can achieve efficient energy management while maintaining the system's fast responsiveness and communication reliability.

[0165] In some embodiments, the second wireless communication chip is capable of accessing a power-specific wireless local area network.

[0166] Specifically, the second wireless communication chip can replace the traditional Ethernet or optical fiber connection to achieve network access for power equipment, simplify wiring, and reduce construction costs.

[0167] Thus, through this configuration, in terms of monitoring and management of the power system, the second wireless communication chip can provide efficient, safe and reliable wireless communication, thereby improving the efficiency and reliability of the power system and reducing operating costs.

[0168] In some embodiments, the communication module enables the first wireless communication chip to communicate with the second wireless communication chip.

[0169] Specifically, the first wireless communication chip and the second wireless communication chip communicate with each other to achieve functions such as joint positioning, data transmission, system control, and network expansion, providing a more flexible, efficient, and reliable communication solution for power equipment.

[0170] Thus, through this configuration, the communication module can provide more flexible and reliable communication while optimizing performance and power consumption, thereby meeting diverse communication needs and improving user experience.

[0171] In some embodiments, the communication module can implement ranging based on the first wireless communication chip.

[0172] Specifically, the specific location of the target device can be calculated using the distance information between multiple Bluetooth devices using a triangulation positioning algorithm.

[0173] Thus, through this configuration, the communication module can provide efficient and accurate ranging functions, thereby optimizing positioning services and improving user experience.

[0174] An embodiment of the present application provides an electronic device, and the electronic device includes the above-mentioned communication module.

[0175] Specifically, electronic devices can access the power-specific WAPI wireless LAN to achieve high-speed and secure network connection. In addition, they can transmit data with other devices equipped with communication modules, such as uploading device status information and downloading software updates. In addition, electronic devices can use WiFi and Bluetooth joint positioning technology to achieve high-precision positioning and real-time tracking of device location information, which is suitable for scenarios such as on-site operation and maintenance of power equipment and safety monitoring.

[0176] In this way, in the electronic device of the implementation mode of the present application, by integrating the above-mentioned communication module, the electronic device can provide an efficient and accurate ranging function, thereby optimizing the positioning service, improving the user experience and meeting diverse needs.

[0177] In some embodiments, the electronic device includes a mobile terminal and / or a power device.

[0178] Specifically, the mobile terminal can collect the status information and operation data of the power equipment and upload them to the operation and maintenance platform. It can also remotely control the power equipment, such as switchgear, adjust parameters, etc. In addition, the mobile terminal can use WiFi and Bluetooth joint positioning technology to achieve high-precision positioning and navigation, which is convenient for operation and maintenance personnel to perform on-site operations. In addition, the mobile terminal can sense the approach of people around and report security incidents, such as illegal people approaching and abnormal stay.

[0179] Power equipment can transmit its own status information, operating data, etc. to the operation and maintenance platform. In addition, power equipment can perform self-control according to preset programs or instructions, such as automatically switching equipment on and off, adjusting parameters, etc. Power equipment can use built-in WiFi and Bluetooth chips for positioning, which facilitates equipment management by operation and maintenance personnel. In addition, power equipment can sense the approach of people around it and report security events, such as equipment being moved, blocked, covered, etc.

[0180] In this way, by connecting through the communication module, functions such as data collection, equipment control, positioning navigation, and security monitoring can be realized, providing guarantees for the safe operation and efficient management of electronic equipment.

[0181] The embodiment of the present application provides an operation and maintenance platform, which can generate a positioning heat map according to the first communication module identification code of the communication module uploaded by the communication module connected to the operation and maintenance platform, the location of the communication module, the first neighbor node information table and the second neighbor node information table, wherein the first neighbor node information table is obtained by scanning the location of the communication module by the first wireless communication chip of the communication module, and the second neighbor node information table is obtained by scanning the location of the communication module by the second wireless communication chip. A positioning library is constructed according to the positioning heat map to locate the communication module according to the positioning library.

[0182] Specifically, first, after the communication module establishes a connection with the operation and maintenance platform, the information uploaded by the communication module includes: the first communication module identification code, the location of the communication module (such as longitude and latitude), the first neighbor node information table, and the second neighbor node information table. Then, the operation and maintenance platform maps the WiFi and Bluetooth signal strengths to the map based on the received information to generate a positioning heat map. The positioning heat map can intuitively display the distribution of WiFi and Bluetooth signal strengths around the communication module. Then, the operation and maintenance platform stores the positioning heat map information together with the communication module identification code, location and other information to build a positioning library. The positioning library records the WiFi and Bluetooth signal strength information of each communication module at different locations.

[0183] When a communication module needs to be located, the operation and maintenance platform can query the WiFi and Bluetooth signal strength information of the communication module from the positioning library. The operation and maintenance platform compares the queried signal strength information with the currently scanned signal strength information to determine the possible location of the communication module.

[0184] It should be noted that in some embodiments, when building the positioning library, a drone with a high-speed positioning module is used to fly around the power infrastructure to record the network SSID, MAC address, signal strength, and three-dimensional coordinate network information table of the WiFi and Bluetooth scans above the current building and power infrastructure, and transmit them back to the operation and maintenance platform.

[0185] In this way, the operation and maintenance platform receives the first neighbor node information table and the second neighbor node information table collected by the wireless communication chip using two different communication protocols to build a positioning library, which can significantly improve the accuracy and reliability of positioning, expand the positioning coverage, optimize network planning and management, support multi-technology integration, enhance user experience, and reduce maintenance costs, thereby comprehensively improving the performance and efficiency of the communication system.

[0186] In some embodiments, the operation and maintenance platform can perform identity authentication processing on the first communication module identification code when the first communication module identification code sent by the communication module is received for the first time, or when an abnormality occurs in the communication connection with the communication module. Then, if the identity authentication processing passes, a security certificate associated with the first communication module identification code is generated according to the first communication module identification code. Subsequently, verification feedback information associated with the communication module is generated according to the security certificate and the first communication module identification code. Finally, the verification feedback information is sent to the communication module to establish a communication connection with the communication module.

[0187] Specifically, when the operation and maintenance platform receives the first communication module identification code sent by the communication module for the first time, or when an abnormality occurs in the communication connection with the communication module, the operation and maintenance platform will initiate an identity authentication request. Then, the operation and maintenance platform performs identity authentication based on the first communication module identification code, such as querying the database, comparing information, etc. After the identity authentication process is passed, the operation and maintenance platform will send the relevant information to the authentication server, and the authentication server will generate a security certificate associated with the first communication module identification code. Subsequently, the operation and maintenance platform generates verification feedback information associated with the communication module based on the security certificate and the first communication module identification code, including security certificates and configuration parameters. Finally, the operation and maintenance platform sends the verification feedback information to the communication module. After receiving the verification feedback information, the communication module will use the security certificate to establish an encrypted communication connection with the operation and maintenance platform.

[0188] In this way, the operation and maintenance platform can securely establish a communication connection with the communication module and ensure security throughout the entire communication process, helping to prevent unauthorized access and data leakage while ensuring the stability and reliability of communication.

[0189] In some embodiments, the operation and maintenance platform can perform identity authentication processing on the first communication module identification code when it is not the first time to receive the first communication module identification code sent by the communication module and the communication connection with the communication module is normal. Then, if the identity authentication processing passes, verification feedback information associated with the communication module is generated according to the first communication module identification code. Finally, the verification feedback information is sent to the communication module to establish a communication connection with the communication module.

[0190] Specifically, first, when the operation and maintenance platform receives the first communication module identification code sent by the communication module for a non-first time and the communication connection with the communication module is normal, it will initiate an identity authentication request. Then, the operation and maintenance platform performs identity authentication based on the first communication module identification code, such as querying the database, comparing information, etc. After the identity authentication process is passed, the operation and maintenance platform will generate verification feedback information associated with the communication module. The operation and maintenance platform sends the verification feedback information to the communication module. After receiving the verification feedback information, the communication module will use the verification feedback information to establish a communication connection with the operation and maintenance platform.

[0191] In this way, the operation and maintenance platform can securely establish a communication connection with the communication module and ensure security throughout the entire communication process, helping to prevent unauthorized access and data leakage while ensuring the stability and reliability of communication.

[0192] See also Figure 5 An embodiment of the present application provides a communication system, which includes the electronic device and operation and maintenance platform as described above.

[0193] Specifically, by connecting electronic equipment with the operation and maintenance platform, remote monitoring, management and maintenance of power equipment are achieved, improving the operating efficiency and security of the communication system.

[0194] For example, see Figure 6 , Figure 6 It is a schematic diagram of the power communication system architecture. Among them, the mobile operation terminal, concentrator and measurement terminal are all integrated with communication modules. The communication methods used by other devices have been marked in the figure. For example, the switch and the measurement terminal communicate based on the power line transmission technology (Broadband Power Line Communication, BPLC). The power line transmission technology realizes the transmission of data on the power line by modulating the data signal to the high frequency band of the power line, thereby realizing power line communication. 4 / 5G is used for communication connection between the measurement terminal and the distribution automation master station. The operation and maintenance platform includes an intelligent operation and maintenance platform, a unified cryptographic service management platform, an identification server and a positioning database. It should be noted that in some embodiments, except for the mobile operation terminal, the concentrator and the measurement terminal, the above-mentioned equipment can be connected to the communication by an externally connected router or other communication connection device. In addition, the intelligent operation and maintenance platform, the unified cryptographic service management platform, the identification server and the positioning database can also be implemented by different devices respectively.

[0195] Thus, through this configuration, the communication system can provide efficient and accurate communication and positioning services, thereby improving system efficiency.

[0196] In some embodiments, the electronic device includes a mobile terminal, and the mobile terminal can upload the scanned information obtained by scanning to the operation and maintenance platform, and the scanned information includes a first neighbor node information table and a second neighbor node information table. Then, the operation and maintenance platform can determine the current positioning information from the positioning library based on the scanned information and send it to the mobile terminal. Then, the mobile terminal can receive the current positioning information sent by the operation and maintenance platform. Finally, the mobile terminal can determine the target navigation route based on the received target location, the scanned information and the current positioning information.

[0197] Specifically, the mobile terminal scans the surrounding devices equipped with communication modules, obtains neighbor node information, and forms a first neighbor node information table and a second neighbor node information table. Subsequently, the mobile terminal uploads the scan information to the operation and maintenance platform. Then, the operation and maintenance platform searches for matching records in the positioning library based on the scan information to determine the current location of the mobile terminal. After determining the current location of the mobile terminal, the operation and maintenance platform sends the positioning information of the mobile terminal to the mobile terminal. Then, the mobile terminal receives the positioning information sent by the operation and maintenance platform. Then, the mobile terminal uses a path planning algorithm to determine the target navigation route based on the received target location, scan information, and current positioning information.

[0198] Continuing with the above example, see Figure 6 When the mobile operation terminal enters the distribution automation master station area, the mobile operation terminal first uses the first wireless communication chip based on the Bluetooth protocol to communicate with each device in the distribution automation master station area. After each device in the distribution automation master station area identifies the data information sent by the mobile operation terminal, it determines that the mobile operation terminal is legal. Subsequently, the first wireless communication chip in the measurement terminal will wake up the second wireless communication chip. Then, the communication module in each device in the distribution automation master station area starts scanning and obtains scanning information. The mobile operation terminal sends the obtained scanning information to the wireless access point through the measurement terminal, and then uploads it to the operation and maintenance platform.

[0199] The operation and maintenance platform searches for matching records in the positioning database based on the scan information to determine the current location of the mobile operation terminal. After determining the current location of the mobile operation terminal, the operation and maintenance platform sends the positioning information of the mobile operation terminal to the wireless access point, then to the measurement terminal, and finally to the mobile operation terminal. In this way, the mobile operation terminal obtains the current positioning information and can perform subsequent operations based on the positioning information to complete different tasks.

[0200] It should be noted that when the mobile operation terminal enters the power consumption information collection master station area, the processing methods of the mobile operation terminal and each device in the power consumption information collection master station area are similar to those of entering the distribution automation master station area mentioned above, and will not be repeated here.

[0201] In this way, the mobile terminal can upload scanning information to the operation and maintenance platform and receive the current positioning information issued by the platform. By combining the target location, scanning information and current positioning information, real-time positioning and navigation of the mobile terminal can be achieved, which facilitates the operation and maintenance personnel to conduct inspections and maintenance of power equipment, improves operation and maintenance efficiency, reduces operation and maintenance costs, and improves safety.

[0202] In some embodiments, the electronic device further includes a power device, and the mobile terminal can determine a first navigation route according to the target location and the current positioning information. Then, based on a preset ranging method, the second navigation route is determined according to the signal strength of the first wireless communication chip in the power device located on the first navigation route, the multiple temporary scanning information obtained by moving along the first navigation route, and the positioning information corresponding to each temporary scanning information. Finally, the target navigation route is determined according to the first navigation route and the second navigation route.

[0203] Specifically, the first navigation route refers to a rough route determined based on the target location and current positioning information, without taking the actual situation into consideration.

[0204] The preset distance measurement method refers to a high-precision distance measurement method.

[0205] The second navigation route refers to a relatively safe and convenient route obtained by continuously scanning data information using the first wireless communication chip and continuously correcting based on the data information.

[0206] The mobile terminal uses WiFi and Bluetooth signals to locate and obtain the current location. The mobile terminal determines the target location based on task requirements or input from operation and maintenance personnel.

[0207] First, the mobile terminal plans a first navigation route based on the current position and the target position. Then, the mobile terminal moves along the first navigation route and uses a preset ranging method to measure the signal strength of the first wireless communication chip in the power equipment along the way. In addition, the mobile terminal scans at different locations along the way, obtains temporary scanning information and uploads it to the operation and maintenance platform. The operation and maintenance platform determines the temporary location of the mobile terminal based on the temporary scanning information and sends the positioning information to the mobile terminal. Subsequently, the mobile terminal plans a second navigation route based on the signal strength and temporary location of the power equipment along the way. Finally, the mobile terminal determines an optimal target navigation route based on the first navigation route and the second navigation route, taking into account factors such as signal strength, distance, and environment. In this way, by measuring the signal strength of the power equipment along the way in real time, the mobile terminal can dynamically adjust the navigation route according to signal changes, avoid areas with weak signals or interference, and ensure communication quality.

[0208] In this way, the mobile terminal can achieve more accurate navigation route determination by integrating the signal strength of the power device and the temporary scanning information. Furthermore, by combining the first navigation route and the second navigation route, the mobile terminal can consider the influence of the power device and other potential navigation obstacles, thereby determining the optimal target navigation route.

[0209] In some embodiments, the electronic device includes an electric device, and the electric device can scan the location based on a first preset period to obtain a first neighbor node information table. Then, the electric device can determine an unauthorized electronic device record table based on the first neighbor node information table and a pre-constructed historical access record table, and the unauthorized electronic device is an electronic device that accesses the electric device at intervals of multiple preset periods. Finally, the electric device can report access anomalies to the operation and maintenance platform based on the access status of the unauthorized electronic device.

[0210] Specifically, the first preset period refers to a period during which the power equipment performs scanning and reporting, and is used to confirm access status of other equipment.

[0211] At preset intervals (for example, every minute), the power equipment uses WiFi and Bluetooth to scan the surrounding neighbor node information, including MAC addresses and signal strengths. The scanned neighbor node information table is compared with the pre-built historical access record table. If it is found that some neighbor nodes (electronic devices) only access the power equipment at multiple preset intervals (for example, a few days), they are identified as unauthorized electronic devices. Based on the access of unauthorized electronic devices, the power equipment will report access abnormalities to the operation and maintenance platform. In this way, by analyzing the access frequency of neighbor nodes, unauthorized electronic devices can be identified, such as devices that enter the area around the power equipment without permission. In addition, the ability to detect access by unauthorized devices in a timely manner helps to improve the security of power equipment and prevent potential damage or attacks.

[0212] In this way, power equipment can detect and report abnormal access through periodic scanning and pre-built historical access record tables, thereby ensuring the security and reliability of the communication system.

[0213] In some embodiments, the power equipment can scan the location based on the second preset period to obtain the first neighbor node information table and the second neighbor node information table. Then, the first neighbor node information table is compared with the first historical neighbor node information table in the historical area positioning heat map. Subsequently, the second neighbor node information table is compared with the second historical neighbor node information table in the historical area positioning heat map. Finally, when the first neighbor node information table is inconsistent with the first historical neighbor node information table, and the second neighbor node information table is inconsistent with the second historical neighbor node information table, the location change of the power equipment is confirmed and reported to the operation and maintenance platform.

[0214] Specifically, the second preset period refers to a period during which the power equipment performs scanning, and is used to confirm the location of the equipment. The first preset period may be the same as or different from the second preset period, and is not limited here.

[0215] The power equipment uses WiFi and Bluetooth to scan the surrounding neighbor node information every preset period (for example, every minute), and obtains the first neighbor node information table and the second neighbor node information table respectively. The first neighbor node information table is compared with the first historical neighbor node information table in the historical area positioning heat map, and the second neighbor node information table is compared with the second historical neighbor node information table in the historical area positioning heat map. If the first neighbor node information table is inconsistent with the first historical neighbor node information table, and the second neighbor node information table is inconsistent with the second historical neighbor node information table, it means that the location of the power equipment has changed. The power equipment reports the location change event to the operation and maintenance platform. In this way, by comparing the neighbor node information table, it can be determined whether the power equipment has been moved, and reported in time so that the operation and maintenance personnel can take corresponding measures. In addition, if the power equipment is illegally moved or stolen, the location change reporting function can be used to timely discover and take measures to prevent the loss of the equipment. In addition, timely understanding of the operating status of the power equipment can help the operation and maintenance personnel to better maintain and manage it and improve the operation and maintenance efficiency.

[0216] This allows power equipment to detect and report location changes through periodic scans and historical area location heat maps, thereby ensuring the security and reliability of the communication system.

[0217] In certain embodiments, the power equipment can confirm that a regional power outage has occurred at the location of the power equipment when neither the power equipment nor its neighbor nodes report the first communication module identification code of the power equipment, the location of the power equipment, the first neighbor node information table, and the second neighbor node information table for at least one period.

[0218] Specifically, the power device reports its first communication module identification code, location, first neighbor node information table and second neighbor node information table at a preset period (e.g., every 10 minutes). In addition, the neighbor nodes of the power device (e.g., other power devices or WiFi / Bluetooth access points) also regularly report their first communication module identification code, location, first neighbor node information table and second neighbor node information table.

[0219] If the power equipment and all neighboring nodes do not report information for at least one period, it means that a power outage may occur in the area. The operation and maintenance platform determines that a power outage has occurred in the power equipment in the area. In this way, by detecting the reporting status of the power equipment and its neighboring nodes, the power outage area can be quickly identified and the operation and maintenance personnel can be notified in time to handle it. In addition, timely understanding of the power outage situation can help the operation and maintenance personnel take quick measures to restore power supply and reduce the impact of the power outage on users.

[0220] In this way, power equipment can detect and report regional power outages by performing periodic scans, thereby ensuring the security and reliability of the communication system.

[0221] An embodiment of the present application provides a positioning method, which is implemented based on the above-mentioned communication system.

[0222] Specifically, when a power inspector needs to locate a distribution box for maintenance, the inspector starts the handheld terminal, turns on the positioning function of the handheld terminal, and connects to the nearby WiFi network. The handheld terminal obtains the MAC address and signal strength of the surrounding WiFi access points by scanning the WiFi signal, and performs rough positioning in combination with the historical record information to determine the approximate area of ​​the distribution box. The inspector approaches the distribution box based on the approximate location displayed by the handheld terminal. When the handheld terminal is close to the distribution box, the Bluetooth channel sounding function is activated to perform high-precision distance measurement to determine the specific location of the distribution box. Based on the positioning information, the handheld terminal provides the inspector with a navigation route to guide them to the distribution box.

[0223] In this way, through the positioning function, inspection personnel can quickly find the electrical equipment that needs maintenance, saving time and energy.
