摘　　要：为解决在人工抄录居民燃气表数据的过程中存在的错抄、漏抄及工作效率低等问题,设计了一种基于复合通信网络的燃气表自动抄表系统。该系统由燃气表、采集器、集中器、主站和通信信道五个模块构成。选取RS-485总线、型号为Si4432的RF芯片和GPRS网络构成复合通信网络服务系统通信信道的底层、中间层和上层,并对系统的采集器、集中器的相关模块电路分别进行了设计。For the sake of solving the problems of the wrong check, lack reading and inefficiency in the process of gas meter reading by manual meter reading, an automatic meter reading system based on the composite communication network was presented. This system consisted of five modules which are automatic gas meter, data collector, concentrator, master station and communication channel. The composite communication network has RS--485 for bottom communication, Si4432 RF chip for mid-level communication and GPRS network for upper-layer communication. And the modules of data collector and concentrator were designed respectively.
