Abstract

The invention provides a climate compensator for saving energy, which is mainly applied to a central heating system. The compensator essentially consists of a CPU circuit, a top right corner memory circuit, a right above clock circuit, a top left corner three-way acquisition circuits, a right left operating indicating circuit, a communication circuit and a PWM output interface, a left lower cornercontrolling outputting circuit, a right below keyboard input circuit, a right lower corner acquiring inputting circuit, a right chip selecting circuit and a display circuit. According to the change of the outdoor temperature, an outdoor temperature parameter is acquired by the acquiring circuit; and according to a set temperature-water supplying compensation curve and by computing with a main CPU, the climate compensator solves a proper water supplying temperature, automatically controls the water supplying temperature by adjusting an electric three-way valve to change the water flow size ofa pipeline, and realizes the climate compensation of the water supplying temperature and the outdoor temperature of a heat supplying system, so as to guarantee that a heating object (room temperature)to be stabilized in a temperature range needed by a customer.

Description

Climate compensator

Affiliated technical field:

It is purpose with energy-conservation that the utility model relates to a kind of, can be in central heating system according to the variation of outdoor temperature, by gathering the outdoor temperature parameter, obtain appropriate adjusting supply water temperature according to the curve of setting, automatically control supply water temperature, the weather compensation of supply water temperature in the realization heating system is stabilized in the interior climate compensator of temperature range that the user needs to guarantee heating object (room temperature).

Background technology:

At present, known climate compensator is external production, is made up of indicating graduation table, knob, the time relay, signals collecting, output, and climate compensator is controlled supply water temperature by gathering outdoor temperature by the variation of outdoor temperature, reaches energy-conservation purpose.But because the difference of domestic construction thing heat insulating ability, the resistance of ducting, boiler thermal output, the setting of compensated curve can not be general, and being inconvenient to of setting, the use difficulty when causing actual use, makes the energy-saving effect of climate compensator not reach designing requirement.

Summary of the invention:

For the complexity that overcomes existing climate compensator curve setting, the deficiency of using inconvenience, the utility model provides a kind of climate compensator, this climate compensator can not only make things convenient for setting curve, and can pass through self-learning function, adjustment curve is obtained appropriate supply water temperature automatically in real time, controls supply water temperature automatically, and adopt Chinese liquid crystal display, keyboard operation makes the user can easily setup parameter and use, has increased the network communication function simultaneously.

The technical scheme that its technical problem that solves the utility model adopts is: autonomous Design goes out special-purpose single chip circuit, the control software that comprises control circuit, memory circuit, Acquisition Circuit, output circuit, display circuit, communicating circuit and independently write.Gather, show and export by the control of the master cpu in the single-chip microcomputer.Carry out computing by gathering the data of coming, obtain appropriate numerical value output (control supply water temperature), and can set by the parameter of user's reality according to the parameter of curve of setting, automatically computing memory, provide best curve, user's operation is convenient in Chinese liquid crystal display simultaneously.

The beneficial effects of the utility model are, 1, the user can come setup parameter easily according to the heating equipment performance of oneself.2, according to user's the setup parameter and the outdoor temperature of collection, to obtain appropriate supply water temperature value, regulate the electric three passes valve opening by output signal and control supply water temperature, reach energy-conservation purpose.3, master controller (CPU) adopts Philips 80C552, controls collection, storage, demonstration, output circuit respectively, and overall structure is integrated.Can report to the police automatically when 4, breaking down, and stop to regulate electric T-shaped valve, recover the electric control valve original state, be applicable to the automatic adjusting of central heat supplying system.

Description of drawings:

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a schematic block circuit diagram of the present utility model.

Fig. 2 is circuit theory diagrams of the present utility model.

Fig. 3 is the control flow chart of climate compensator.

Digital ID among Fig. 1 is corresponding with Fig. 2.Among Fig. 1, the 1st, host CPU (80C552), the 2nd, storage chip (27C512, HY62256), the 3rd, clock chip (DS12C887), 4 is 3 tunnel Acquisition Circuit (LM258), the 5th, RS232 communicating circuit and PWM output interface, the 6th, control output (HC245), the 7th, gather input (HC245), 8 chip select circuits (GAL22V10D), 9 display circuits (KS0108B), 10 running status indicating circuits (HC573), 11 keyboard input circuits (HC245, HC573).

Fig. 3 is the control flow chart of an embodiment of climate compensator, gather signal by Acquisition Circuit (4), be that parameter of user is given host CPU (1) by keyboard input (7) simultaneously, process is stored in the computing of the program of storage chip (2) lining, show that (9) are on liquid crystal display, according to computing relatively, output (6) needs controlled element to control, reaches the adjusting purpose.

The specific embodiment:

At the main circuit control chip is the upper right corner layout memory circuit (2) of host CPU (1), directly over arrange (3) clock circuit, (4) eight tunnel Acquisition Circuit have been arranged in the upper left corner, front-left is arranged (10) operation indicating circuit and (5) communicating circuit and PWM output interface, (6) control output circuit is arranged in the lower left corner, arranged just beneath (11) keyboard input circuit, the lower right corner are arranged (7) collection input circuit, and front-right is arranged (8) chip select circuit and (9) display circuit.

After this climate compensator system powers on, gather signal by Acquisition Circuit (4), be about to outdoor temperature, supply water temperature, the return water temperature sensor signal, convert the 4-20mA current signal to, be connected with host CPU (1), be the parameter of user signal by keyboard input (7) simultaneously, give host CPU (1), generate to regulate and use compensated curve, process is stored in the computing of the program of storage chip (2) lining, show that (9) are on liquid crystal display, simultaneously according to the PID computing relatively, output (6) control signal is transferred to needs controlled element: electric T-shaped valve, rationally control valve opening, make supply water temperature constant in range of set temperature, reach make user indoor temperature be stabilized in 18 the degree about the adjusting purpose.When breaking down, as sensor fault, electric T-shaped valve fault, system's automatic forced adjustment electric three passes valve opening is to maximum.
