For reaching above-mentioned purpose, the application's technical scheme is as follows:
It comprises intelligent regulator and is installed in temperature sensor and electric control valve in the building water return pipeline of heat supply unit, temperature sensor is connected with the temperature signal input interface of intelligent regulator by lead, and electric control valve is connected with the motor valve output interface of intelligent regulator by lead.
The circuit structure of above-mentioned intelligent regulator is: a whole set of circuit adopts modularized design, and it comprises hardware mainboard CPU MSP430F123 (mainboard comprises I/O interface and modular jack, display interface socket, A/D converting unit and power subsystem), temperature sensor signal input interface, cold-junction compensation circuit, built-in comparator, temperature indicator, communication interface, clock module, clock setting display, relay and the motor valve interface of high universalizable.Input working procedure in the mainboard, the size that intelligent controller regularly opens or closes electric control valve or opens electrically operated valve according to the height of temperature according to the temperature of each time period of setting, thereby the flow of control thermal source.
In addition, also can on intelligent regulator, be furnished with the interface that is applicable to LAN, link to each other with industrial computer, printer in the control room by RS232/485 converter and RS-485 transmitting device.By the monitoring software of special use, realize following function:
1) monitors each building return water temperature in real time, in time adjust the heat exchange station operational factor, reach the purpose that guarantees normal heat supply and energy savings.
2) real time record Information Monitoring forms history curve, trend curve and various form, is convenient to statistics and heat supply analysis.
3) can adjust design temperature in real time according to Changes in weather and heat supply needs, the by-pass valve control aperture satisfies heat supply needs and energy savings to greatest extent indirectly.
4) make up perfect man-machine interface, make the adjusting of device directly perceived, simple, easy row.
5) can make full use of user's LAN resource, be connected on the management level microcomputer, make administrative staff retrieve for examination the heating situation at any time by switch.
The application's effect is: improved the utilization rate of heat energy, realized the heat supply equilibrium, thereby reached energy saving purposes.
