2. Full data collection and real-time uploading

The module has powerful data acquisition capabilities and can connect 32 digital input signals (DI) and 16 digital output signals (DO) to real-time collect information such as switch status, fault signals, and operation instructions of power distribution equipment; Simultaneously supporting the collection of electrical parameter data (such as current, voltage, power, electrical energy, etc.) from intelligent instruments and protection devices through RS485 interface. After being processed by the module, the collected data will be uploaded to the monitoring center or cloud platform with a response speed of milliseconds, ensuring that the upper level system can grasp the real-time operation status of the distribution network.

3. Remote control and command issuance

Based on bidirectional communication capability, the module can receive remote control instructions issued by the upper level monitoring system, such as circuit breaker opening and closing, equipment start and stop, parameter configuration, etc., and accurately transmit the instructions to the executing device through the DO interface or communication bus. Data encryption and verification mechanisms are used during instruction transmission to prevent instruction loss or tampering, ensuring the security and reliability of remote operations. In addition, the module supports switching between local manual operation and remote control, and emergency control can be achieved through local buttons in case of communication interruption, improving the system's fault tolerance.

4. Fault warning and diagnostic function

The module has built-in fault monitoring and diagnostic logic, which can monitor its own communication status, interface connection status, and abnormal operation of connected devices (such as communication interruptions, signal abnormalities, etc.) in real time. When a fault is detected, it will immediately trigger a local indicator light alarm and send fault alarm information to the monitoring center through the communication network, including detailed data such as fault type, occurrence time, and fault location. At the same time, the module can store the last 100 fault records, providing strong support for operation and maintenance personnel to trace the cause of faults and quickly troubleshoot problems.

5. Redundant backup and security protection

To ensure the continuity of the communication system, the module supports dual network port redundancy backup function. When the main communication link fails, it can automatically switch to the backup link with a switching time of less than 100ms, ensuring uninterrupted data transmission. In terms of security protection, the module has an IP30 protection level and integrates overvoltage and overcurrent protection circuits internally, which can effectively resist power grid fluctuations and instantaneous impacts; Simultaneously supporting access permission management, restricting illegal operations by setting usernames and passwords to prevent malicious intrusion into the system.
