On the base of the overseas advanced technology,a city central heating network automation system,which is suitable for China,has been developed and used.

View of remote distance monitor and detection on operation parameters of boiler in the city heating supply network, the communication scheme based on public telephone network is proposed, and hardware.

In view of the remote distance monitor and detection on operation parameters of boiler in the city heating supply network, the wireless communication scheme based on GSM is proposed, and hardware system of double micro-controllers is designed.

Calculation and analysis on insulation thickness of heating pipes;

Harms of corrosion of heating pipe and reasons of causing corrosion are analysed.

Research on the economic analysis software of heating network;

Failure rate statistics and spectrum analysis of heating network components based on an investigation;

Analysis on first adjustment measures of heating pipe network;

The failure reasons and prevention measures of corrugated expansion joint in heating pipe network;

It develops the network distributed fault monitoring system, solves the questions of heating pipe network fault real-time monitor and special fault incentive discrimination and reduces the error rate of system fault.
