Description

A kind of humidifier intelligence control system

Technical field

The utility model relates to humidifier technical field, particularly be a kind of humidifier intelligence control system.

Background technology

Existing humidifier generally uses hand switch, user is needed to open and close humidification action as required, certain running time is needed because humidifier reaches humidifying effect, this humidifier in use,, there is the problem of excessive humidification and dry combustion method, be unfavorable for health in the humidity change big rise and fall of indoor environment, there is potential safety hazard, operate also very loaded down with trivial details.

Utility model content

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of humidifier intelligence control system.

The utility model solves the technical scheme that its technical problem adopts: a kind of humidifier intelligence control system, include temperature sensing module, level sensor module, microprocessor, humidifier module and display module, the output signal of described level sensor module is transferred to microprocessor through A/D module, the output signal of described microprocessor is transferred to humidifier module, described microprocessor respectively with temperature sensing module and display module bidirectional data communication.

Further, described temperature sensing module adopts DS18B20 temperature sensor IC3.

Further, described level sensor module is connected successively by HM21 sensor IC 4 and output thereof resistance R5, electric capacity C4, resistor R8 and LTC1297 integrated chip IC2 are formed.

Further, described microprocessor adopts AT89C51 single-chip microcomputer IC1.

By adopting above-mentioned technical scheme, the beneficial effects of the utility model are: the utility model is reasonable in design, with low cost, realize the display of anti-dry in humidification, intelligent switch and real-time parameter, substantially realize the intellectuality of humidification, be suitable for large-scale mass production.

Accompanying drawing explanation

Fig. 1 is frame assumption diagram of the present utility model;

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

Detailed description of the invention

The utility model is further illustrated below in conjunction with the drawings and specific embodiments.

As shown in Figure 1, a kind of humidifier intelligence control system of the present utility model, include temperature sensing module, level sensor module, microprocessor, humidifier module and display module, the output signal of described level sensor module is transferred to microprocessor through A/D module, the output signal of described microprocessor is transferred to humidifier module, described microprocessor respectively with temperature sensing module and display module bidirectional data communication.Described temperature sensing module detects indoor temperature, level sensor module detecting humidifier water level inside (needing AD conversion), data reach microprocessor in real time, by making comparisons with the temperature preset and waterlevel data, control the switch motion of humidifier module and make humidifier work, temperature information when display module shows this and humidifier water level inside information.

As shown in Figure 2, described temperature sensing module adopts DS18B20 temperature sensor IC3, and due to this built-in chip type AD conversion, output signal is required binary code.Signal pins is driven high through resistance R2 to VCC, when exporting " 0 ", electric current flows into DS18B20 temperature sensor IC3, be low level with AT89C51 single-chip microcomputer IC1 connecting line, when exporting as " 1 ", be high level with AT89C51 single-chip microcomputer IC1 connecting line, a signal is transmitted 12 times in same intervals.

The resistance R5 that described level sensor module is connected successively by HM21 sensor IC 4 and output thereof, electric capacity C4, resistor R8 and LTC1297 integrated chip IC2 are formed, HM21 sensor IC 4 good stability, and full scale, zero-bit long-time stability can reach 0.1%FS/.HM21 sensor IC 4 exports corresponding voltage value according to present position hydraulic pressure dynamics by its 1st pin, the adjustable output amplitude of resistance R5, electric capacity C4 is to signal filtering, and resistance goes R8 current limliting, and voltage signal is inputted by the 2nd pin of LTC1297 integrated chip IC2, be 12 binary codes by this level by internal conversion through A/D chip, 1st, 6,7 pin of LTC1297 integrated chip IC2 and the 21st of AT89C51 single-chip microcomputer IC1 the, 22,23 pin form IIC tie line.At all after dates of a simulated clock simulation clock, data import AT89C51 single-chip microcomputer IC1 into, for preventing data signal and analog signal from interfering with each other, here will digitally and in analog be connected in series with the resistance of one 0 ohm.

Humidifier module is by resistance R1, and R3, R6, optocoupler U1 and humidifier switch are formed.When having abundant water resources but temperature is too high, the P1.2 pin that AT89C51 single-chip microcomputer IC1 is connected with optocoupler U1 exports a low level, and the anode of optocoupler receives VCC end by resistance R6, now optocoupler U1 conducting, humidifier circuit turn-on.Described display module is external liquid crystal interface, facilitates dismounting and the maintenance of liquid crystal.Because the P0 port (inside does not have pull-up resistor, if need to draw high level as during common I/O mouth) of AT89C51 single-chip microcomputer IC1 linked by 8 bit parallel data lines, an external pull-up resistor draws high I/O level.The human-computer interaction interface that display module provides, to information displaying such as temperature humidity.

Above-describedly be only a preferred embodiment of the present utility model, the scope that the utility model is implemented can not be limited, every equalization change of doing according to the utility model claim and decoration, all should still belong in scope that the utility model contains.
