[0021] The technical effects obtained by the module are as follows: First, by integrating a multi-protocol conversion chip and a level conversion circuit, a perfect signal adaptation and protocol conversion hardware platform is constructed, which can effectively solve the problem of level mismatch between different devices, and provides a physical basis for the access of various heterogeneous equipment (such as battery management systems and environmental monitoring units of different manufacturers) and intelligent devices (such as intelligent circuit breakers and digital protection units), and eliminates technical obstacles for device interconnection from the hardware level.

[0022] Second, the IEC104 protocol stack and the configurable special protocol driver built-in the module realize the bidirectional conversion function between the standard power protocol and the private protocol. This configuration not only supports flexible configuration of communication parameters, enabling devices using different communication protocols to exchange data without obstacles, but also enables dynamic mapping of data models, enabling devices following different communication standards to exchange data at the semantic level; and successfully connects key devices (such as auxiliary contacts and fault signals of dual-power switching devices) that use special protocols to the unified monitoring system.

[0023] Third, by pre-setting the key communication parameters such as baud rate, data bits, stop bits, and check bits, the module realizes self-adaptation to different physical interfaces such as RS-485 and Ethernet and various communication scenarios. This highly flexible configuration strategy not only effectively solves the problem of device access caused by communication parameter mismatch, but also fundamentally breaks the long-standing data island phenomenon in power monitoring systems. By seamlessly connecting various heterogeneous devices (such as intelligent circuit breakers and battery monitoring units) that use different communication specifications to the unified system, the device compatibility and system expandability of the entire monitoring platform are significantly improved, laying a solid technical foundation for building a truly open and integrated intelligent monitoring platform.

The over-voltage protection circuit is composed of a zener diode and a field effect transistor, which are connected in parallel. When the output voltage exceeds the threshold, the power supply is cut off. The over-current protection circuit is composed of a current detection resistor and a comparator, which are connected in parallel. When overcurrent is detected, the protection action is triggered to ensure the safe and stable operation of the gateway.

[0029] The technical effects achieved by the module are as follows: First, in terms of power quality, the module adopts high-efficiency switching power supply combined with rectification, filtering, voltage conversion, and voltage stabilization function units, which can convert fluctuating external input power into the precise and stable voltage required by each module. This precise power processing technology provides pure and reliable power supply for the precision electronic components inside the gateway, ensuring the stability of the system operation.

[0030] Second, in terms of safety protection, the module's overvoltage and overcurrent protection circuit forms a perfect safety protection system. The overvoltage protection circuit can quickly cut off the power supply when the voltage abnormally rises to prevent high-voltage impact from damaging sensitive components. The overcurrent protection circuit can monitor the load current in real time and trigger protection action immediately when short circuit or overload occurs, effectively preventing accidents from expanding.

[0031] Third, in terms of environmental adaptability, the module's reinforced design enables it to withstand common power fluctuations and transient pulses in industrial environments.

At the same time, the circuit breaker is equipped with auxiliary contacts and fault signal nodes, which can be monitored by the acquisition gateway in real time to monitor the power on-off state and collect fault signals, achieving comprehensive monitoring of system operation status. It can solve the reliability problem of high-frequency power switch cabinet AC switching system and monitoring system. By using a dual-power automatic switching device with mechanical and electrical double locking functions, the power supply reliability of the high-frequency power switch cabinet AC switching system is significantly improved, reducing the wiring between components, increasing the mechanical locking between the two power supplies, reducing the contactor action, and effectively avoiding the risk of two-way AC power loop operation. At the same time, the auxiliary contacts and fault signal nodes of the circuit breaker in the device, combined with the new acquisition gateway and multiple sensors, achieve comprehensive real-time monitoring of the power on-off state, fault signals, battery voltage and internal resistance, as well as cabinet hydrogen, smoke sensing, and temperature and humidity environmental parameters, and comprehensively enhance the system's state awareness ability and operation reliability.
