This technology uses the unified architecture and flexible assembly characteristics of the Dianhong IoT operating system to achieve the intelligence, interconnection and collaboration of power equipment, providing strong support for the digital transformation of the power industry.

[0018] As a new generation of industrial Internet of Things operating system for power industry terminals, Dianhong IoT operating system has the characteristics of unified system, unified standards, interconnection of all things, and safety and reliability. For the first time, it has realized a system covering large and small power equipment, and through a unified protocol, equipment from different manufacturers can be intelligently interconnected. All key technologies of this system are self-developed, including soft bus communication for power detection scenarios, near-field discovery and connection functions. Through Dianhong IoT operating system, we can realize intelligent management of power equipment, improve equipment operation efficiency, and reduce operation and maintenance costs.

[0019] The Dianhong IoT operating system and soft bus self-discovery technology can be widely used in power production links such as power generation, transmission, transformation, distribution, power consumption, dispatching, new energy, water storage and energy storage. For example, in the power transmission scenario, this technology can be used for self-discovery and connection of terminal equipment such as patrol inspection, environmental monitoring, and online monitoring; in the power distribution scenario, it can be used for intelligent management of environmental collection terminals, equipment collection terminals, circuit breakers, monitoring, security and other equipment.

[0020] In this regard, the present invention provides a soft bus self-discovery technology for running a lightweight Dianhong IoT operating system, and the implementation process of the technology is as follows:

[0021] 1. Device Scan

[0022] The Dianhong IoT operating system broadcasts a scan request in the substation network through soft bus technology. The request contains necessary information such as device type and communication protocol so that the IoT device can respond based on this information.

[0023] 2. Device Identification

[0024] After receiving the scanning request, the IoT devices in the substation system will respond according to their own device type and communication protocol. The response information includes device identification, device status, etc., so that the Dianhong IoT operating system can accurately identify the device and determine whether it meets the connection conditions.

[0025] 3. Device connection

[0026] According to the device identification results, the Dianhong IoT operating system establishes a connection with the IoT device through soft bus technology. During the connection process, communication and data exchange between devices are realized, providing a basis for subsequent device management.

[0027] 4. Equipment Management

[0028] Once the device is successfully connected, the Dianhong IoT operating system will add the device to the management list and manage the connected IoT devices in a unified manner. Management functions include device status monitoring, data collection, remote control, etc., to ensure stable operation and efficient collaboration of the devices.

[0029] The following is a further description of the preferred embodiment of the present invention in conjunction with specific implementation methods;

[0030] 1. Device Scan

[0031] After the Dianhong IoT operating system is started, it will immediately start the device scanning process. Through the soft bus technology, the system will broadcast a device scanning request in the substation system network. The request not only contains basic information such as device type and communication protocol, but may also include other specific requirements for the equipment required by the system, such as device performance, safety level, etc.

[0032] In order to ensure that the scan request can be received by each IoT device in the substation system network, the system may use multiple broadcasts or incremental broadcast radius to ensure that the scan request can cover the entire substation system network.

[0033] Specifically, the in-depth and example description of device scanning:

[0034] In the substation system, when the Dianhong IoT operating system starts the device scanning process, it will use the soft bus technology to broadcast a scanning request with specific protocols and parameters in the network. For example, the system may need to find a smart meter that supports the Modbus communication protocol or a surveillance camera with a specific security level.

[0035] Scan requests are not only sent through broadcast, but may also be sent through multicast or unicast to perform more accurate scanning for specific areas or specific devices. For example, in a specific area of ​​a large substation, the system can use multicast to scan only the devices in that area, improving scanning efficiency.

[0036] 2. Device Identification

[0037] After receiving a scan request, the IoT device in the substation system will first check the device type and communication protocol in the request to ensure that it meets the requirements. Then, the device will generate a response message based on the instructions in the scan request.

[0038] The response information usually includes the unique identification of the device (such as MAC address or device serial number), the current status of the device (such as online, offline, busy, etc.), device performance parameters (such as processing power, storage capacity, etc.) and security level, etc. This information will be packaged into a standard format and returned to the Dianhong IoT operating system through soft bus technology.

[0039] After receiving the response information, the Dianhong IoT operating system will parse and verify it to ensure the accuracy and completeness of the information. Then, the system will store this information in the device list for subsequent connection and management operations.

[0040] Specifically, the refinement and example description of device identification:

[0041] After receiving the scan request, the device generates a response message according to the instructions in the request. For example, a smart meter may return its serial number, current power, voltage, current and other real-time data, as well as its online status and communication protocol version.

[0042] After receiving this information, the Dianhong IoT operating system will verify and analyze it, store it in the database, and create a file for each device. The system can also use this information to classify and group devices for subsequent management and operation.

[0043] 3. Device connection

[0044] Device connection is a key step in establishing communication between the Dianhong IoT operating system and IoT devices. Based on the device identification results, the system will determine which devices to connect to and select the appropriate communication protocol and connection method.

[0045] During the connection process, the system may use encryption technology to ensure the security of communication. At the same time, the system will monitor and record the connection process so that it can locate and solve problems in time when the connection occurs.

[0046] Once the connection is successful, the Dianhong IoT operating system can conduct two-way communication and data exchange with IoT devices, including sending control instructions, receiving device status information, and obtaining device data.

[0047] Specifically, the detailed description and example of device connection:

[0048] During the device connection phase, the Dianhong IoT operating system will select the appropriate connection method based on the device type and communication protocol. For example, for devices that support TCP / IP protocol, the system may use socket connection; for devices that support Bluetooth, the system will use Bluetooth connection.

[0049] During the connection process, the system may also use handshake protocols and encryption technology to ensure the security and stability of the connection. For example, when establishing a connection, both parties will exchange and verify keys to ensure that only legitimate devices can access the system.

[0050] 4. Equipment Management

[0051] Device management is the process by which the Dianhong IoT operating system manages and controls connected IoT devices in a unified manner. The system will add connected devices to the management list and assign a unique management ID to each device.

[0052] Through the management list, the system can monitor the status, performance and data of the equipment in real time. At the same time, the system can also remotely control the equipment according to needs, such as adjusting equipment parameters, executing specific tasks, etc.

[0053] In addition, the Dianhong IoT operating system also has equipment fault detection and early warning functions. When a device fails or an abnormal situation occurs, the system can detect it in time and issue early warning information so that operation and maintenance personnel can handle it quickly.

[0054] Specifically, the extension and instance description of device management:

[0055] Device management is one of the core functions of the Dianhong IoT operating system. The system can not only monitor the status and data of the device in real time, but also perform remote control, parameter adjustment and other operations.

[0056] For example, when the system detects abnormal data from a smart meter, it can automatically trigger an alarm mechanism to notify the operation and maintenance personnel to handle it. At the same time, the system can also predict and analyze the operating status of the equipment based on historical data and real-time data to provide decision support for the operation and maintenance personnel.

[0057] In addition, the system can also discover the operating patterns and potential problems of the equipment through data analysis and mining, providing a basis for equipment optimization and upgrading.

[0058] In summary, through the four steps of device scanning, device identification, device connection and device management, the Dianhong IoT operating system can realize automatic discovery, connection and management of IoT devices in the substation system, improving the intelligence level and operation efficiency of the system. In short, through in-depth expansion and example illustration, we can have a more comprehensive understanding of the specific methods and processes of the Dianhong IoT operating system to realize automatic discovery, connection and management of devices in the substation system. This not only improves the intelligence level of the system, but also improves the operation efficiency and management level of the substation system.
