Background technology:
China is energy shortage country, also is power consumption big country.Root a tree name national statistics department announces that 100,000,000 tons in China's annual urban heating quota of expenditure coal is equivalent to consume hundred million tons of raw coal 1.4-1.5, and its heating power consumption does not also comprise the power consumption of rural area heating power consumption and urban electric power, rock gas, oil.
The existing heat supply heating mode of China mainly shows as: 1, the heat supply zone is big, has caused the uneven in temperature of heat supply temperature; The too hot heat radiation of need opeing the window wastes energy, the too cool effect that does not have heating installation.Can't regulate heating-amount according to the time when 2, heating, for example: office needs heating during working, does not After Hours need heating; Dormitory will heat when staying evening, did not need heating during unmanned live.But present heating all is uninterrupted heating in 24 hours, and awareness of saving energy is poor, has wasted a large amount of energy.3, extensive style operation, heating press area and is charged, thin user's awareness of saving energy.4, the area of heat-supply service owing to each caliber is different with heating demand in heating system, causes uneven heating weighing apparatus between each heat supply unit.
Summary of the invention:
The application's purpose is the above-mentioned deficiency that overcomes existing heating system, proposes a kind of building heat supply intelligent regulating system, thus design temperature heat supply in reaching automatically on time, heat supply on a time period and and the purpose of heat supply equilibrium, and then energy savings.
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 modular 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 supply unit), temperature sensor signal input interface, cold junction compensation circuit, built-in comparer, temperature indicator (TI), 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 of the LAN (Local Area Network) of being applicable to, link to each other with industrial computer, printer in the pulpit by RS232/485 converter and RS-485 transmission system.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 system directly perceived, simple, easy row.
5) can make full use of user's LAN (Local Area Network) resource, be connected on the administration and supervision authorities microcomputer, make managerial personnel retrieve for examination the heating situation at any time by switch.
The application's effect is: improved the utilization factor of heat energy, realized the heat supply equilibrium, thereby reached energy saving purposes.

Embodiment
With reference to the accompanying drawings embodiment is described in detail below.
As shown in Figure 1: the original-pack infinite variable speed multifunctional motor-driven variable valve 3 with electronic actuator of temperature sensor (platinum resistance thermometer sensor) 2 and Germany is installed in the building water return pipeline 1 of each water supply unit, and temperature sensor 2 is connected with intelligent regulator 4 by lead with electric control valve 3.Temperature sensor 2 is measured the water temperature in the water return pipeline constantly, and measured temperature is passed to the CPU center of intelligent regulator 4, clock module 16 is connected with CPU, measure temperature and after 12 compensation of cold junction compensation circuit, compare (relatively) by built-in comparer 13 with design temperature (setting) by establishing temperature indicator (TI) 14, when if the measurement temperature is lower than setting value, intelligent regulator 4 is just exported high level signal and is given electric control valve 3, at this moment electric control valve 3 valve open maximums; If when the measurement temperature was higher than setting value, intelligent regulator 4 was given electric control valve 3 with regard to the output low level signal, this moment, electric control valve 3 valve closings stopped heat supply.When the closed condition of clock setting, measure temperature temperature compensated with design temperature relatively after, if when measuring temperature and being lower than setting value, intelligent regulator 4 is just exported high level signal and is given electric control valve 3, this moment, electric control valve 3 valves appropriateness was opened; If when the measurement temperature was higher than setting value, intelligent regulator 4 was given electric control valve 3 with regard to the output low level signal, at this moment electric control valve 3 valve closings.Intelligent regulator 4 can manually be provided with temperature and time as special product independently, also can be connected on the industrial computer 6 by RS485/RS232 converter 5, carries out Long-distance Control.Industrial computer 6 is loaded onto special-purpose monitoring software, is regulated and control by computer real-time.Monitoring in real time, managerial personnel can in time adjust the operational factor of heat exchange station, reach the purpose that guarantees normal heating and energy savings; And can the real time record Information Monitoring, forming history curve, trend curve and various form are then by the needed information of printer 7 printouts.Industrial computer 6 can also be connected on the administration and supervision authorities microcomputer 9 by the network switch 8, calls at any time for managerial personnel and checks.
