在进行系统方案设计时，考虑到以后系统的扩展及有关部门需求的增加，没有采用集中式的主机系统结构，决定用网络结构，以便扩充和设备的更新;进行网络选型论证时，考虑到系统扩充及维护的简易性，决定选用总线形结构的网络：为了提高系统的稳定性、可靠性，没有采用单主机总线网络结构，采用多主机网络总线结构。F7133 HIMA

采用多主机分布式监测方式，它具有以下特点：
适应能力强，可以通过选用适当数量的上位机和数据采集站来构成相应规模的系统，便于扩展。
可靠性高，某个主机或采集站出现故障，不会对系统的其他主机或采集站造成影响。当一个采集站出现故障时，只影响本采集站的功能。当一个主机出现故障时，可由其他主机“代管”。
实时响应性好，各个数据采集站之间是真正“并行”工作，因此，系统的实时响应性好。
与单主机监测系统相比，不易造成“瓶颈”现象。
整个系统上位机选用工控机，下位机选用智能测控前端，每台上位机配有1台UPS，主控室和集控室分别配1台打印机。系统总体结构如图1所示。
