At present, the heat supply network is mainly operated under human monitoring system, so it is difficult to find out fault and issue fault alarm on time;while untimely maintenance may bring unnecessary losses even cause accidents. Aiming at this status, the heat supply network monitoring and remote maintenance system based on Internet has been designed and implemented. The Internet information server ( IIS) is setup and Android client is designed; the server and thermal station communicate with mobile phone via Socket protocol, data transmission unit ( DTU) and push module. The functions of data acquisition, real time monitoring fault alarm, and remote control of the heat supply network are implemented by mobile phone client with help of Baidu map by API call.%目前热网主要采用人为监控制度，存在难以及时发现故障和发出故障报警的弊端，维护不及时会造成不必要的损失甚至事故。针对该现状，设计并实现了基于互联网的热网监控及远程维护系统。搭建IIS服务器并设计Android手机客户端，服务器、热力站和手机通过Socket协议、DTU和推送模块进行数据通信，借助百度地图API 调用百度地图，实现手机客户端对热网系统的数据采集、实时监控、故障报警、远程控制等功能。
