| The growing problem of environmental pollution and energy shortage has aroused high attention all over the world,People carried out corresponding measures from each aspect of the society to address the problem.In the northern area of our country,people need heating against the winter cold weather,the heating way to scattered boiler consumed a lot of energy,and caused serious pollution to the environment,so in recent years which has been gradually replaced by the centralized heating.The centralized heating is provided with heat from the heat source factory outside of the city,which can greatly reduce energy waste and environmental pollution.The heat transfer station as an intermediate link between heat source and heat users,is the key of the centralized heating.Through the system,all kinds of real-time parameters in heat transfer station and operation of each device can be monitored.It can adjust the running state of heat transfer station,so it plays an important role to ensuring the quality of heating and stable operation of the heat transfer station.The topic is engineering project of the enterprise of Shanxi Province,Xinzhou City,according to project requirements and the actual situation of the scene,the heat supply network monitoring system is designed to remote monitor and control the heat transfer stations of the city.This paper introduces the present status and development trend of domestic central heating,the structure and the working principle of the heat exchange station.Through the analysis and comparison of the heat exchange station control method,and considering various factors,the specific control of the project is determine.It Introduces the IC card prepayment system,which avoid accounting disputes from the energy supply and demand sides,it is convenient for management,and let the energy using units have a understanding of consumer.This topic uses the SHCAN2000 field bus control system to realize the data acquisition of heat transfer station and control of actuators on the scene.Using APN network realize the communication between the Thermotics Inc and the heat transfer station.In the free wiring case,the remote data transmission is realized. The touch screen is used in the station to realize the local control.In the monitoring and dispatching center,the FIX monitoring software is used to realize the remote control.Through the software,the unmanned operation is achieved.Various faults occurred in the network can be founded and treated effectively.The establishes a convenient, safe and stable monitoring system of heat supply network. |
