1. Problem Introduction
Urban thermo stations are scattered around all over the city. The admin department needs to monitor the parameters like temperature, pressure, flow, level etc. at real-time and control the linkage operation of equipment in thermo stations. Meanwhile, in order to keep stable operation every day in winter, managers have to make adjustment according to the parameters they monitored of each station. The condition is that our operation management I s under manual operation which causes problems like less comprehensive parameters measurements, operation under imperfect thermo parameters and so on.
Based on that, Micro sensor explores a set of urban thermo monitor system to solve the problem. By measuring, control and transmission of the temperature, pressure, flow and switches, this system can remotely measure, sense, control and adjust the thermo process effectively. It helps to know the operation at real time and comprehensively, monitors the differential pressure of the adverse condition spot. The whole system can ensure the urban thermo system run safe and reasonably and adjust automatically due to the data and offer accurate effective and key data for the thermo department.
2. System Introduction and Work Flow
Our central heating supply system includes three parts: thermo power, thermo network, thermo customers. The thermo power creates steam or hot water and offer all urban customers with industrial and livelihood thermo. The thermo exchange station is the connection of thermo network and thermo customers, the “thermo exchange station” between the thermo power and thermo customers. The efficient operation of the exchange station plays a role in improving the strength and quality of thermo supply.
Thermo exchange station consists of primary net return water system, second net return water system, supply water system and thermo measurement system and all parts effect each other. Water in thermo power connects to thermo exchange station with the primary supply water pipes and circulate back to thermo power by the primary net return pipes. After thermo exchange in the exchange station, water in second net is offered to customers through the pipes and return through the second net return network and offer thermo to customers circularly.
3.The system topological graph
The thermo exchange station monitor the temperature, pressure, flowmeter thermo parameters. The whole system includes local sense, data process, net transmission and systematic application.
Local sense includes gauges like site equipment, temperature transmitter, pressure transmitter, flow meter, water pump/valve control, monitoring parameters at real time.
4.Monitoring terminal of Thermo Exchange Station
This terminal includes data collection, local control, display and remote communication. It is set by website and can connect many pressure sensors, pressure transmitters as well as controllers.
This terminal is Saturn500. We use it to collect both the primary and second net monitor data, communicate with monitor center and company control center through different ports.
5. Monitor Platform
Micro sensor has developed our independent management platform for the urban thermo supply monitoring system, both PC and mobile version are available. This plat form can be used for real-time monitoring, history check, trace analysis and display visibly.
