An intelligent gateway module for building electrical monitoring system is designed based on the microcontroller STC12CSA60S2. In the module,the independent L-N fieldbus interface is designed to support the communication with the lower-layer monitoring LAN, and the USB interface chip PDI- USBD12 and integrated Wi-Fi module HLK-RMO4 are adopted to support the upper-layer USB or Wi- Fi communication. It implements the conversion between the underlying communication protocol and the upper-layer communication protocol. Thus the monitoring server or the mobile client can be sup- ported to control the electrical equipment that is linked to the underlying fieldbus node through I/O interfaces. The results of experimental and application tests show that the designed gateway module is of high reliability and real-time performance, and can meet the application needs for developing the in- dependent building electrical monitoring system.
