Design of Intelligent Concentrator basing on M-BUS and Embedded Linux

摘要

Design an intelligent concentrator of heat meter reading system for residence. ARM9 processor is adopted to be the core of the hardware construction; modular hardware drivers and functional design are placed in this device. The software of the concentrator adopted embedded Linux. M-BUS communication protocol is used to implement the data transmission between the concentrator and the heat meters. This device has the features of security data transmission, convenient reading and strong realtime.
