摘　　要：针对机房监控系统中底层设备与上层软件因紧密耦合导致系统维护困难的问题,采用适配器模式和桥接模式设计了底层数据采集接口,实现现场设备、远程监控端、数据网关之间的松散耦合,将DCOM技术作为数据处理的模型,使网关服务器可以提供远程分布式监控服务。实验结果表明,该设计方式实现了底层设备的多型号多协议兼容,降低维护成本,具有较好的可复用性和可扩展性。Aiming at the problem of the difficult circumstances of system maintenance caused by tight coupling of bottom equipments and upper software in many engine monitoring systems, this paper uses the combination of bridge and adapter pattern to design the bottom data acquisition interfaces, which implements the loose coupling between field devices, remote monitoring clients and data gateway. The technology of Distributed Component Object Model（DCOM） is made as the data processing model, so that the server can provide remote distributed database services. Experimental result proves that this design approach implements multi-protocol and multi-model compatible of the bottom equipment, reduces maintenance costs, and has better reusability and scalability of the system architecture.
