[0042] In addition, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0043] It should be noted that the term "comprising" will be used in the embodiments of the present application to indicate the existence of the features declared thereafter, but does not exclude the addition of other features.

[0044] With the advancement of industrial automation and intelligence, traditional circuit breakers are gradually evolving into intelligent circuit breakers with communication capabilities to meet the needs of real-time monitoring and remote control of power system operating status. Currently, intelligent circuit breakers mostly use wired communication methods (such as RS-485) for networking. This method has improved the interconnection and interoperability between devices to a certain extent, but it still has many limitations in practical applications.

[0045] Although the traditional RS-485 bus communication method has a simple structure, low cost, and is widely used in industrial fields, its performance bottleneck is becoming increasingly prominent:

[0046] 1. It is difficult to balance high speed and long distance: The higher the RS-485 communication rate, the shorter the transmission distance. If long-distance communication is required, a repeater must be introduced, which increases system complexity and deployment costs.

[0047] 2. Limited number of nodes: The standard RS-485 bus supports a maximum of 32 nodes, which limits the system's scalability and makes it difficult to adapt to the needs of large-scale device access.

[0048] 3. High delay in master-slave communication mode: RS-485 usually uses the master device to poll the slave device for communication. The slave device cannot actively report information, resulting in high response delay and affecting the real-time performance of the system.

[0049] 4. Difficult wiring and complex maintenance: RS-485 communication requires matching terminal resistance (usually 120Ω) to prevent signal reflection; at the same time, its series structure leads to complex wiring, and the installation and subsequent maintenance workload is large.

[0050] 5. Single topology: RS-485 only supports bus topology and cannot flexibly adapt to diversified network structures such as star and ring, which limits its applicability in different application scenarios.

[0051] To overcome the drawbacks of wired communication, some smart circuit breakers have begun to adopt wireless communication methods in recent years, such as Bluetooth and Wi-Fi (wireless local area network). However, these technologies also have obvious drawbacks:

[0052] 1. Bluetooth communication distance is short and the number of node connections is limited: Bluetooth has a short effective communication distance (usually within 10 meters) and can only support a small number of device connections (generally no more than 7), which makes it difficult to meet the needs of networking a large number of devices in industrial environments.

[0053] 2. Wi-Fi communication has weak anti-interference ability and high power consumption: Although Wi-Fi communication has high bandwidth and good network access capabilities, its anti-interference ability is poor and it is easily interfered by signals from other electronic devices, causing packet loss or communication interruption. In addition, the Wi-Fi module has high power consumption and is not suitable for applications in low-power scenarios.

[0054] 3. Security risks: Wi-Fi communication has security risks such as illegal access and data eavesdropping, and lacks sufficient security protection mechanisms, which is not conducive to the safe operation of industrial equipment.

[0055] In summary, existing intelligent circuit breakers generally rely on traditional wired or short-range wireless communication technologies for communication, which have problems such as short communication distance, poor networking flexibility, limited number of nodes, difficult deployment and maintenance, and poor real-time performance, which seriously restrict their application and promotion in complex industrial environments.

[0056] Based on this, this solution provides a circuit breaker networking system. By configuring a first target communication chip for each circuit breaker device in the circuit breaker cluster and a second target communication chip for each communication gateway in the gateway cluster, the first target communication chip and the second target communication chip are both integrated with at least the Star Flash communication protocol, so that the communication gateway can establish a network topology with the circuit breaker device through the Star Flash communication protocol. Since the Star Flash communication method combines the advantages of traditional wireless communications such as Bluetooth and Wi-Fi, it has lower latency, lower power consumption, wider coverage, and a higher safety factor connection technology. It can effectively improve the data transmission efficiency and transmission distance between the circuit breaker device and the communication gateway, and overcome the problem of limited number of circuit breaker device connections. While ensuring communication reliability, it can improve networking capabilities, reduce deployment and maintenance costs, and meet the needs of industrial-grade remote monitoring and management.

[0057] Figure 1 A schematic diagram of the architecture of a circuit breaker networking system provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the system may include: a circuit breaker cluster, a gateway cluster, a cloud service platform and a mobile terminal; the circuit breaker cluster includes multiple circuit breaker devices, each of which is equipped with a first target communication chip; the gateway cluster includes multiple communication gateways, each of which is equipped with a second target communication chip; the first target communication chip and the second target communication chip are at least integrated with the Star Flash communication protocol; each communication gateway establishes a network topology with each circuit breaker device through the Star Flash communication protocol; each communication gateway is also interconnected with the cloud service platform through the local area network communication protocol; the cloud service platform establishes a communication connection with the mobile terminal through the network communication protocol.

[0058] Communication gateways and circuit breaker devices can be networked together in a one-to-many networking mode. This means that a communication gateway can establish connections with one or more circuit breaker devices, forming a relay communication path to improve overall network coverage and stability. Networks between gateway clusters and circuit breaker clusters can be established using various topologies, including star, mesh, and hybrid topologies.

[0059] The Star Flash communication protocol supports Mesh network topology and multi-hop relay to expand communication coverage.

[0060] In this embodiment, the system can flexibly build the network topology according to the actual situation:

[0061] Among them, the star topology is suitable for centralized deployment, where all circuit breaker devices are directly connected to the communication gateway; the mesh topology is suitable for wide-area distribution scenarios, where circuit breaker devices can serve as relays for each other; and the hybrid topology combines star and mesh structures, taking into account both communication efficiency and coverage.

[0062] The system can automatically identify different topologies and build optimal communication paths to improve networking flexibility.

[0063] The circuit breaker devices in the circuit breaker cluster can refer to the aforementioned intelligent circuit breakers. The first target communication chip configured in the circuit breaker device and the second target communication chip configured in the communication gateway can be the same chip. The first target communication chip can be embedded in the circuit breaker device to serve as the core communication unit for the circuit breaker device. Similarly, the second target communication chip can be embedded in the communication gateway to serve as the core communication unit for the communication gateway. Both the first target communication chip and the second target communication chip integrate at least the StarFlash communication protocol, enabling the circuit breaker cluster to be networked with the gateway cluster using the StarFlash communication protocol.

[0064] In some embodiments, the communication gateway can establish a network interconnection with the cloud service platform via Wi-Fi. The cloud service platform can communicate with the mobile terminal via a network security communication protocol such as MQTT (Message Queuing Telemetry Transport) / HTTP (Hypertext Transfer Protocol) / CoAP (Constrained Application Protocol) to establish a data synchronization channel.

[0065] Each circuit breaker device uploads the circuit breaker operating parameters to the cloud service platform through the communication gateway.

[0066] Optionally, the circuit breaker device may send the collected circuit breaker operating parameters to the corresponding communication gateway in real time, and the communication gateway may upload the circuit breaker operating parameters to the cloud service platform.

[0067] The circuit breaker operating parameters uploaded by the circuit breaker device include but are not limited to:

[0068] Electrical parameters: synchronous collection of current, voltage, power factor, harmonic components, etc.; protection parameters: three-stage protection curve (long-time protection, short-time protection, instantaneous protection), action setting value, time setting value; operation log: fault recording data, fault information data, equipment health status.

[0069] It is worth noting that the above electrical parameters are collected and uploaded in real time, while the protection parameters and operating parameters are uploaded when changes or updates are detected.

[0070] The communication gateway has the ability to cache and forward data, and can receive and broadcast control instructions from the cloud service platform while the circuit breaker device actively uploads the circuit breaker operating parameters.

[0071] The cloud service platform sends the circuit breaker operating parameters of each circuit breaker device to the mobile terminal, which then displays them visually.

[0072] The cloud service platform is equipped with a circuit breaker device management interface and a real-time database to receive and store circuit breaker operating parameters uploaded by the circuit breaker device through the communication gateway. At the same time, the cloud service platform can also send the received circuit breaker operating parameters to the mobile terminal for visual display.

[0073] The mobile terminal responds to the user's operation on the application interface, generates a remote control instruction, and sends the remote control instruction to the cloud service platform to remotely control the specified circuit breaker device based on the cloud service platform.

[0074] Optionally, the mobile terminal can send opening and closing control instructions to the cloud service platform. Of course, in addition to this, parameter configuration instructions, protection parameter reading instructions, fault record information reading instructions, health information reading instructions, etc. can also be sent.

[0075] The mobile terminal is installed with management application software, which integrates a device status visualization module and a remote control module. The remote control module receives actions triggered by the user through the application interface, generates remote control commands, and sends these commands to the cloud service platform. The cloud service platform then sends the remote control commands to the designated circuit breaker device through the communication gateway to achieve remote control of the circuit breaker device. The management application software provides the user with an application interface, and the device status visualization module can visualize the various data received or read.

[0076] This embodiment uses remote control and two-factor authentication mechanisms to enhance data management and control. The following describes how to implement the remote control function and its security measures.

[0077] Users submit remote control commands to the cloud service platform through the mobile terminal's application interface; the commands must be verified by a two-factor authentication mechanism, which includes: device fingerprint binding: each circuit breaker device has a unique ID, and only authorized users are allowed to operate; dynamic verification code verification: a one-time verification code must be entered before each operation; after the remote control command is signed by the cloud service platform, it is broadcast to the designated circuit breaker device through the communication gateway for execution; after the designated circuit breaker device completes the execution, the feedback information is sent back to the cloud service platform and synchronized to the mobile terminal; the entire process supports operation log recording to facilitate subsequent auditing and tracing.

[0078] In summary, the circuit breaker networking system provided in this embodiment includes: a circuit breaker cluster, a gateway cluster, a cloud service platform, and a mobile terminal; the circuit breaker cluster includes multiple circuit breaker devices, each of which is equipped with a first target communication chip; the gateway cluster includes multiple communication gateways, each of which is equipped with a second target communication chip; the first target communication chip and the second target communication chip are integrated with at least the Star Flash communication protocol; each communication gateway establishes a network topology with each circuit breaker device through the Star Flash communication protocol; each communication gateway is also interconnected with the cloud service platform through the local area network communication protocol; the cloud service platform establishes a communication connection with the mobile terminal through the network communication protocol; each circuit breaker device uploads circuit breaker operating parameters to the cloud service platform through the communication gateway; the cloud service platform sends the circuit breaker operating parameters of each circuit breaker device to the mobile terminal, which visually displays them;

[0079] The mobile terminal responds to user operations on the application interface, generates remote control instructions, and sends remote control instructions to the cloud service platform to remotely control the specified circuit breaker equipment based on the cloud service platform. This method configures a communication chip integrated with the Star Flash communication protocol in the circuit breaker equipment and the communication gateway, so that a network topology can be established between the circuit breaker cluster and the gateway cluster through the Star Flash communication protocol, realizing Star Flash communication, improving the data transmission efficiency and transmission distance of the circuit breaker equipment, improving the network coverage and stability, and expanding the number of connections of the circuit breaker equipment. While ensuring communication reliability, it can improve networking capabilities, reduce deployment and maintenance costs, and meet the needs of industrial-grade remote monitoring and management.

[0080] Figure 2 This is a schematic diagram of the architecture of another circuit breaker networking system provided in an embodiment of the present application. Optionally, the first target communication chip and the second target communication chip further integrate a Bluetooth communication protocol and a local area network communication protocol.

[0081] In some embodiments, the first target communication chip and the second target communication chip may integrate, in addition to the StarFlash communication protocol, a Bluetooth communication protocol and a local area network communication protocol (Wi-Fi communication protocol). The first target communication chip and the second target communication chip may be tri-mode communication chips, supporting StarFlash communication, Bluetooth communication, and Wi-Fi communication.

[0082] If the communication gateway detects that the signal strength of the Star Flash communication link between the circuit breaker device is lower than the preset threshold, the Star Flash communication protocol communication mode between the circuit breaker device will be switched to the Bluetooth communication mode through the Bluetooth communication protocol or to the LAN communication mode through the LAN communication protocol.

[0083] Of course, in addition to integrating the Star Flash communication protocol, the first target communication chip and the second target communication chip may also integrate the Bluetooth communication protocol or the LAN communication protocol, that is, at least one of the Bluetooth communication protocol and the LAN communication protocol may be integrated.

[0084] By integrating other communication protocols besides the StarFlash protocol into the first and second target communication chips, a multi-protocol redundant transmission mechanism can be implemented. When the communication gateway detects that the StarFlash communication link signal strength between it and the circuit breaker device is below a preset threshold, it deems the StarFlash communication link signal weak and potentially at risk of interruption. At this point, it can automatically switch to a Bluetooth or Wi-Fi communication link.

[0085] Among them, it is possible to switch to the Bluetooth communication mode through the Bluetooth communication protocol, or to switch to the Wi-Fi communication mode through the Wi-Fi communication protocol.

[0086] In one possible scenario, under normal working conditions, the circuit breaker device and the communication gateway mainly communicate through the Star Flash communication protocol; when the signal strength of the Star Flash communication link is lower than the set threshold, the system automatically switches to the Bluetooth communication protocol for data transmission; if the Bluetooth signal is also interfered with, the Wi-Fi communication protocol is enabled as a backup communication channel.

[0087] The Bluetooth communication protocol serves as auxiliary communication, providing short-distance redundant connection when the star flash signal is weak; the Wi-Fi communication protocol realizes local debugging and data upload functions of circuit breaker equipment in specific scenarios.

[0088] Among them, the switching mechanism can be automatically completed by the built-in algorithm of the second target communication chip configured in the communication gateway without human intervention; all communication protocols support data encryption and identity authentication to prevent illegal access and data tampering.

[0089] Through the above-mentioned multi-protocol redundancy design, the system can still maintain stable communication quality in complex industrial environments, meet the business requirements of high availability and high reliability, and ensure that data is not lost.

[0090] Optionally, the communication gateway is connected to the encrypted tunnel of the cloud service platform through the local area network communication protocol to realize the uplink transmission of the circuit breaker operating parameters and the downlink distribution of the remote control instructions of the circuit breaker equipment.

[0091] In some embodiments, each communication gateway in the gateway cluster can access a local router via the Wi-Fi communication protocol and establish an encrypted tunnel with an external cloud service platform. The encrypted tunnel can be built based on the TLS (Transport Layer Security) / SSL (Secure Sockets Layer) protocol or other symmetric / asymmetric encryption algorithms to ensure the confidentiality and integrity of the transmitted data.

[0092] The gateway cluster supports dynamic switching of master nodes. When a communication gateway encounters network anomalies or performance bottlenecks, tasks will be automatically migrated to other normal communication gateways.

[0093] During the tunnel establishment process, the cloud service platform can authenticate the identity of the accessed communication gateway to prevent illegal devices from accessing.

[0094] Through the above methods, the communication security between the communication gateway and the cloud service platform is improved, data leakage and illegal access are prevented, the system availability and scalability are enhanced, and it is suitable for large-scale Internet of Things deployment; load balancing and fault transfer between communication gateways are achieved, improving the overall system stability; and communication efficiency and service quality are optimized to meet the needs of various application scenarios such as industrial control and smart home.

[0095] Figure 3 This is a schematic diagram of the architecture of another circuit breaker networking system provided in an embodiment of the present application. Optionally, as shown in FIG. Figure 3 As shown, the management application software on the mobile terminal also integrates a parameter configuration module.

[0096] Optionally, the mobile terminal also responds to the user's parameter configuration operation on the application interface, generates circuit breaker configuration parameters, and sends them to the cloud service platform; the circuit breaker configuration parameters include: protection setting values.

[0097] Users can also configure parameters of circuit breaker equipment through the parameter configuration module. Among them, users can set some protection setting values ​​such as current protection setting value, voltage protection setting value, power protection setting value, etc. through the application interface.

[0098] The mobile terminal can send the circuit breaker configuration parameters set by the user to the cloud service platform.

[0099] The cloud service platform sends the circuit breaker configuration parameters to each circuit breaker device through the communication gateway.

[0100] The cloud service platform can send user-defined circuit breaker configuration parameters to each circuit breaker device through various communication gateways. The circuit breaker device can perform circuit protection based on the real-time collected main circuit signals and the set protection setting values.

[0101] For example, if the current protection setting value set by the user is 1500A and the main circuit current collected by the circuit breaker device is 2000A, the circuit breaker device can actively trip to cut off the current fault.

[0102] Continue as Figure 3 As shown, the management application software of the mobile terminal also integrates a firmware upgrade module.

[0103] The mobile terminal also sends firmware upgrade information of the target circuit breaker device to the cloud service platform.

[0104] In some embodiments, the mobile terminal may also push firmware upgrade information to the cloud service platform through the firmware upgrade module to control the firmware upgrade of the circuit breaker device.

[0105] The cloud service platform sends the firmware upgrade information to the target circuit breaker device via the communication gateway to upgrade the firmware of the target circuit breaker device.

[0106] The cloud service platform sends the received firmware upgrade information to the target circuit breaker device via the communication gateway, which may be sent to the processor of the target circuit breaker device, and the processor controls the firmware upgrade of the target circuit breaker device according to the firmware upgrade information.

[0107] Optionally, the cloud service platform verifies the firmware upgrade information according to the verification information in the firmware upgrade information, and executes the update after the verification passes.

[0108] In some embodiments, the firmware upgrade information may include verification information, such as a verification code, which indicates the identity of the mobile terminal and the integrity of the upgrade package. Upon receiving the firmware upgrade information, the cloud service platform may use the verification information contained in the firmware upgrade information to verify the integrity and compliance of the firmware upgrade information. It may also verify the identity of the mobile terminal that sent the firmware upgrade information. If the verification is successful, the cloud service platform sends the firmware upgrade information to the processor of the target circuit breaker device, which then controls the firmware upgrade of the target circuit breaker device. This verification ensures the accuracy of the firmware upgrade.

[0109] In some cases, after receiving the firmware upgrade information, the processor of the target circuit breaker device may perform a secondary verification and execute the update after the verification is correct.

[0110] During the upgrade process, you can keep the old version of the firmware package as a backup to prevent the system from crashing and becoming inoperable.

[0111] Figure 4 This is a schematic diagram of the architecture of another circuit breaker networking system provided in an embodiment of the present application; Figure 4As shown, the data analysis module on the cloud service platform has a pre-trained machine learning model deployed in the data analysis module;

[0112] Based on the machine learning model, the cloud service platform predicts the life of the circuit breaker equipment and warns of circuit risks according to the received circuit breaker operating parameters, and generates warning information.

[0113] In some embodiments, the cloud service platform can identify and process the received circuit breaker operating parameters based on a machine learning model to perform life prediction of the circuit breaker equipment and circuit risk warning, and generate warning information.

[0114] The machine learning model can be trained by learning historical current, voltage and other data.

[0115] On the one hand, the machine learning model can predict the remaining service life of the circuit breaker equipment based on the aging model; on the other hand, the machine learning model can also identify abnormal power usage behavior, such as leakage, overload, short circuit, etc.

[0116] For example, when it is identified that the current gradually increases, a warning message indicating that the current exceeds the set value may be generated; when the current suddenly changes significantly, a warning message indicating that the system is unstable may be generated, and the like.

[0117] The cloud service platform sends the warning information to the mobile terminal for visual display.

[0118] Optionally, the cloud service platform can push the warning information to users via mobile terminals, that is, visualize the warning information through mobile terminals to achieve intelligent operation and maintenance.

[0119] Of course, in some cases, when a downward trend in equipment performance is detected, maintenance reminders can also be pushed to users via mobile terminals.

[0120] Optionally, the communication gateway initiates a star flash broadcast scan to identify at least one circuit breaker device; the communication gateway establishes a network topology with the at least one circuit breaker device.

[0121] In some embodiments, the communication gateway serves as the central node in the Star Flash network and is responsible for initiating Star Flash broadcast scanning to actively discover and access circuit breaker devices within its communication coverage, thereby completing the automatic construction of the Star Flash network topology structure.

[0122] Optionally, the communication gateway can periodically send broadcast frames containing specific identification information and receive response frames from each circuit breaker device, parse the device identification, version information and capability information therein, and then form a complete Star Flash network node list for subsequent data communication management.

[0123] Optionally, the link establishment process between the circuit breaker device and the communication gateway can also be implemented using a two-way handshake mechanism, thereby significantly reducing the device access delay and improving the overall response efficiency of the Star Flash network.

[0124] When a circuit breaker device enters the communication range of a communication gateway, it proactively sends a connection request frame to the communication gateway, containing fields such as device identification, version information, and capability information. Upon receiving the request, the communication gateway determines whether to allow the circuit breaker device to access based on the pre-set security policy. It then generates a connection confirmation frame containing network configuration parameters (such as the assigned logical address, communication channel, and time slot number) and sends it back to the circuit breaker device that initiated the connection request.

[0125] Through this two-way handshake process, the communication gateway and the circuit breaker device complete identity recognition, resource allocation, and link parameter synchronization, establishing a stable point-to-point communication link. This mechanism eliminates the need for the circuit breaker device to send a confirmation frame to the communication gateway, effectively reducing access latency while ensuring security and reliability. It is particularly suitable for scenarios with large-scale concurrent device access.

[0126] The link establishment process is closely integrated with the construction of the StarScan network topology. The communication gateway, as the core controller of the StarScan network, records the network status information of the corresponding circuit breaker device after each successful two-way handshake and updates the global topology table. This topology table includes, but is not limited to, device hierarchical relationships, connection status, communication quality indicators, routing paths, and other information for subsequent data forwarding, resource scheduling, and fault recovery.

[0127] Optionally, the communication gateway receives the circuit breaker operating parameters sent by the circuit breaker device and converts the circuit breaker operating parameters into star flash frame data; after data verification, the star flash frame data is encapsulated into a network communication protocol message, and transmitted to the cloud service platform through the local area network communication protocol.

[0128] After each circuit breaker device is connected to the Starflash network, it collects operating parameters such as voltage, current, power and fault status in its circuit in real time and uploads them to the communication gateway. The communication gateway encapsulates the received raw data into Starflash frame format data for local caching and periodic reporting.

[0129] Optionally, when the original data of the circuit breaker device arrives at the communication gateway, the registered callback function parses the data and converts it into a unified data format according to preset protocol mapping rules to facilitate subsequent encapsulation and forwarding.

[0130] During the data uplink phase, the communication gateway re-encapsulates the converted Star Flash frame data according to the MQTT protocol specification and appends a CRC checksum to ensure data integrity. The MQTT message is then uploaded to the cloud service platform via the WiFi communication protocol using 1024-QAM modulation. 1024-QAM modulation significantly improves the spectrum utilization of wireless links, enabling higher data transmission rates and lower latency within limited bandwidth, making it suitable for concurrent uploads from large-scale circuit breaker equipment.

[0131] The system also includes an anomaly detection and retransmission mechanism. If the communication gateway detects that a circuit breaker device has repeatedly failed to respond to broadcast requests or data uploads have failed, it triggers a reconnection and retransmission process and records relevant logs for operation and maintenance personnel to review. Meanwhile, the cloud service platform unpacks, stores, and analyzes received MQTT messages, and uploads them to mobile terminals for visual display.

[0132] In summary, the circuit breaker networking system provided in this embodiment includes: a circuit breaker cluster, a gateway cluster, a cloud service platform and a mobile terminal; the circuit breaker cluster includes multiple circuit breaker devices, each of which is equipped with a first target communication chip; the gateway cluster includes multiple communication gateways, each of which is equipped with a second target communication chip; the first target communication chip and the second target communication chip are at least integrated with the Star Flash communication protocol; each communication gateway establishes a network topology with each circuit breaker device through the Star Flash communication protocol; each communication gateway is also interconnected with the cloud service platform through the local area network communication protocol; the cloud service platform establishes a communication connection with the mobile terminal through the network communication protocol; each circuit breaker device uploads the circuit breaker operating parameters to the cloud service platform through the communication gateway; the cloud service platform sends the circuit breaker operating parameters of each circuit breaker device to the mobile terminal, which is visually displayed by the mobile terminal; the mobile terminal responds to the user's operation on the application interface, generates a remote control instruction, and issues the remote control instruction to the cloud service platform to remotely control the specified circuit breaker device based on the cloud service platform. This method configures a communication chip integrated with the StarFlash communication protocol in the circuit breaker equipment and the communication gateway, so that a network topology can be established between the circuit breaker cluster and the gateway cluster through the StarFlash communication protocol, realizing StarFlash communication, improving the data transmission efficiency and transmission distance of the circuit breaker equipment, improving the coverage and stability of the network, and expanding the number of connections of the circuit breaker equipment. While ensuring communication reliability, it can improve networking capabilities, reduce deployment and maintenance costs, and meet the needs of industrial-grade remote monitoring and management.

[0133] In addition, by embedding a three-mode communication chip that integrates the Star Flash communication protocol, Bluetooth communication protocol, and Wi-Fi communication protocol, a multi-protocol redundant transmission mechanism can be implemented to maintain stable communication quality in complex industrial environments, meet business needs for high availability and high reliability, and ensure that data is not lost.
