Abstract
The invention relates to an intelligent control system of a valve, which is suitable for a warming system for residents. The intelligent control system is characterized by comprising a temperature controller and an executer which are connected, wherein the temperature controller comprises a singlechip which is respectively connected with a clock chip module, a liquid crystal display module, a key module, a temperature sensor module and a power supply module; and the executor comprises a motor drive circuit and a direct current motor which are connected, the signal input end of the motor drive circuit is connected with the signal output end of the singlechip, and the power supply end of the motor drive circuit is connected with the power supply module. The intelligent control system has the beneficial effects that the valve is opened automatically by outage, indoor temperature is effectively prevented from being overflow or a pipe is prevented from being frost-split; the valve is controlled to be flexibly opened, impact caused by water current to the pipe is avoided; the valve is rotated once every other a time interval, and is prevented from being corroded; and the valve is automatically opened, closed or rotated according to a power supply condition, an indoor temperature and a set time interval.
Description
Technical field
The present invention relates to a kind of valve intelligent control system of the resident's of being applicable to heating system.
Background technology
In recent years, valve control system was widely used in market, office building, supermarket and the household heating system.At present, most valve control systems all comprise temperature controller and electrically operated valve (comprising YE and valve) two parts.Indoor thermostat compares with the temperature value of setting after gathering room temperature, output signal is moved accordingly according to fiducial value control YE, this action drives valve open or closes, and then the circulation fluid of certain heat sent into cooling system by pipeline, so that cooling system begins or quits work, the final purpose that realizes the regulation and control indoor temperature.
There is wretched insufficiency in above-mentioned valve control system, and it can't solve the problem of outage heating.After the outage, valve remains the state before the outage, and this often makes valve be in for a long time closed condition, then makes the indoor temperature continuous decrease, even Indoor Temperature occurs and spend the phenomenons such as low, water pipe from freezing crack.
Summary of the invention
The purpose of this invention is to provide a kind of valve intelligent control system, thereby can prevent that effectively Indoor Temperature from spending low or frost crack pipe at when outage Open valve.
A kind of valve intelligent control system, its special feature is: be comprised of the temperature controller that is connected and actuator, wherein temperature controller comprises single-chip microcomputer, this single-chip microcomputer is connected with clock chip module, LCD MODULE, key-press module, temperature sensor module and power module respectively, and actuator comprises motor-drive circuit and the direct current generator that is connected, wherein the signal input part of motor-drive circuit is connected with the signal output part of aforementioned single-chip microcomputer, and the power end of this motor-drive circuit is connected with the aforementioned power source module.
Wherein the power end of motor-drive circuit is connected with power module by voltage conversion circuit.
The invention has the beneficial effects as follows: 1, outage is automatically with valve opening, and lasting maintenance often opens shape, prevents that effectively Indoor Temperature from spending low or frost crack pipe; 2, by-pass valve control is flexible opens the impact of having avoided current that pipeline is caused; 3, rotate a valve every a period, the corrosion of prevention valve; 4, can according to electric power thus supplied, indoor temperature and setting period, automatically open, close or rotating valve.Control and need not manually, simple and convenient safe and reliable.

Accompanying drawing 2 is logic theory block diagram of the present invention;
Accompanying drawing 3 is control flow chart of the present invention.
The specific embodiment
As shown in Figure 1, 2, valve intelligent control system of the present invention, formed by the temperature controller that is connected and actuator, wherein temperature controller comprises single-chip microcomputer, this single-chip microcomputer is connected with clock chip module, LCD MODULE, key-press module, temperature sensor module and power module respectively, and actuator comprises motor-drive circuit and the direct current generator that is connected, wherein the signal input part of motor-drive circuit is connected with the signal output part of aforementioned single-chip microcomputer, and the power end of this motor-drive circuit is connected with the aforementioned power source module.The power end of motor-drive circuit is connected with power module by voltage conversion circuit in addition.
Operation principle of the present invention is as follows:
Mode of operation 1: when external power cut off the power supply, the battery in the power module of valve intelligent control system was powered to motor-drive circuit.Start working after the motor-drive circuit energising, by direct current generator with valve open after, guaranteed that valve still is in opening when outage.
Mode of operation 2: when external power was powered, valve intelligent control system gathered indoor temperature by temperature sensor module, and the temperature value of single-chip microcomputer and setting compares, and exported corresponding control signal again.Simultaneously, the clock chip module is also started working, and it can export corresponding signal instruction according to the period of setting.
When indoor temperature was lower than design temperature, single-chip microcomputer sent the signal of Open valve.After receiving output signal, motor-drive circuit drives the direct current generator forward, then with valve opening.The circulation fluid of certain heat enters cooling system by pipeline, and after the cooling system heat radiation, indoor temperature continues to rise to the temperature value of setting.
When indoor temperature was higher than design temperature, single-chip microcomputer sent the signal instruction of valve-off.The counter-rotating of direct current generator drive motors is then with valve closing.Cooling system stops heat radiation because can not get replenishing of new thermal source, thereby indoor temperature is remained in the zone of reasonableness.
When integration time of clock chip module when setting the period, single-chip microcomputer sends the signal of rotating valve.After receiving this signal instruction, the motor-drive circuit drive motors is positive and negative respectively to be turned once, to prevent that effectively valve is owing to the corrosion phenomena that is in for a long time single duty and occurs.
Claims (2)
