Design of an embedded multi-function communications control system

An embedded multi-function communications control system is designed for data acquisition and processing in this paper. It consists of two parts by hardware and software. The main applications of the system are monitoring the environment of base station for mobile communications and telecommunications terminal board room. This system can deal the data acquisition and processing for Entrance guard system, Fire fighting apparatus, Dual -Technology Sensor, Explosion-proof device and other Electronic alarm equipments. The system can support a variety of transmission Medias, such as: DDN, Modem dial-up, E1, Ethernet LAN and so on. It can constitute a point-to-point Star Network with the entire remote base stations (End Stations) by above transmission Medias. Its software system can support for the network requirements with at least 64 base stations (End Stations) and even more. Meanwhile, the software system can support the functions of Active-Standby Routing and Handover, and alarm of abnormal communications.
