Background technology
The humidity control and management in the indoor places such as warmhouse booth, experiment production, grain reserves, laboratory at present, most sensation and experiences that still rely on the people, adopt the mode of craft or semi-hand, so not only taken a large amount of tour time of workman, and can not be in time, accurately and efficiently humidity is regulated.
Summary of the invention
The purpose of this utility model is to utilize computer automatic control system management humidity, realize humidity collection and intelligent control and networking, save a large amount of human resources, and can be in time, accurately humidity is regulated, avoid causing damage, the utility model adopts following technical scheme for this reason:
A kind of automatic humidity control system, comprise: sensor, signal processor, watch-dog, controller, overrun alarm and peripherals, the indoor temperature signal of described sensor collection is passed to watch-dog by signal processor, the output terminal of described signal processor is connected with the input end of controller, the input/output terminal of described watch-dog is connected with the input/output terminal of controller, the first output terminal of described controller is connected with overrun alarm, and the second output terminal of described controller is connected with peripherals.
The beneficial effects of the utility model: the utility model is realized the warning to the humidity overrun condition by controller and overrun alarm, by controller and peripherals, makes peripherals carry out running automatically, completes the automatic control of indoor humidity.The utility model circuit is simple, volume is little, cost is low, function is strong, has realized humidity collection and intelligent control, networking, has saved a large amount of human resources, and can be in time, complete humidity regulated accurately.
The accompanying drawing explanation
Fig. 1 is the one-piece construction schematic diagram of the utility model automatic humidity control system;
Fig. 2 is humidity measuring circuit figure;
Fig. 3 is the structural representation of controller;
Fig. 4 is the structural representation of overrun alarm.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail: the present embodiment is implemented take technical solutions of the utility model under prerequisite, provided detailed embodiment, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure 1, a kind of automatic humidity control system that the present embodiment is related, comprise: sensor 1, signal processor 2, watch-dog 3, controller 4, overrun alarm 5 and peripherals 6, the indoor temperature signal that described sensor 1 gathers is passed to watch-dog 3 by signal processor 2, the output terminal of described signal processor 2 is connected with the input end of controller 4, the input/output terminal of described watch-dog 3 is connected with the input/output terminal of controller 4, the first output terminal of described controller 4 is connected with overrun alarm 5, the second output terminal of described controller 4 is connected with peripherals 6.
As optionally, as shown in Figure 2, sensor is selected humidity sensor HS1101.In testing circuit, because HS1101 is capacitance type humidity sensor, its electric capacity is not directly measured, so need utilize NE555N multi resonant oscillating circuit frequency first to be detected, calculate capacitance value by single-chip microcomputer again, finally according to capacitance, calculate corresponding humidity value.The work period of testing circuit:
Charge cycle is T
1=0.7 (R
2+ R
3) C
x;
Discharge cycle is T
2=0.7R
2* C
x;
The output square wave frequency is: f=1/ (T
1+ T
2)=1/[0.7 * (2R
2+ R
3) * C
x]
Visible, when indoor humidity changes, the electric capacity at HS1101 two ends changes, and the output frequency of circuit is also changed along with being inversely proportional.Like this, just can record humidity as long as measure the output frequency of NE555N.Finally control executive circuit and control topworks by the output switch amount of single-chip microcomputer.
As optionally, as shown in Figure 3, controller 3 can adopt single chip computer AT 89S51, utilize the output switch amount of single-chip microcomputer to control peripherals, and single-chip microcomputer adopts photoelectrical coupler to carry out the isolation of light current and forceful electric power, considers that output signal will be triggered controllable silicon, in order to connect executive circuit, therefore by thyristor, realizes and being connected of peripherals, generally thyristor selects existing Trigger Function that the MC3041 of photoelectricity isolation features is arranged again.When peripherals, while being a plurality of, each peripherals is connected respectively with described controller by thyristor.Wherein peripherals can be the equipment such as solenoid valve, sunshade net, blower fan, skylight and wet curtain in Fig. 3.
As optionally, as shown in Figure 4, overrun alarm 5 adopts the low pressure audio-frequency power amplifier, generally select have that low in energy consumption, supply voltage scope is large, the audio frequency integrated amplifier LM386 of voltage gain capable of regulating, the advantage such as element is few and distortion is little, when controller detect that actual humidity surpasses or lower than standard value, surpass higher limit or during lower than lower limit, the voltage signal of the pin output certain frequency of controller 2, after audio-frequency power amplifier amplifies, promote loudspeaker and send identical or different alarm sound.
The beneficial effects of the utility model: controller is mainly realized the detection of humidity and adjusting, the humidity digital signal of indoor each sensor collection is stored, then with the target humidity of deposit, compare, through controlling, calculate, provide the execution instruction, peripherals is turned round automatically, thereby guarantee that indoor humidity is basicly stable.And watch-dog also can be stored data, shown, management and statistical study.
The above; it is only preferably embodiment of the utility model; these embodiments all are based on the different implementations under the utility model general idea; and protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
