Background technology
The feature of humistor is that the resistance value of element all increases when the humidity of in the air increases.Current humidity mistake
High autoalarm, complex structure, relatively costly.
Content of the invention
The present invention relates to the too high automatic control alarm system of humidity, described system includes: dew cell, long resistance, first
Power supply, second source, pressure cell, adjustable resistance, audion, switch and music module；
Described dew cell (rs) one end connect in circuit with one end of a long resistance (r), the first power supply (e0) just
Pole connects the other end of described dew cell, and the negative pole of described first power supply connects the other end of described long resistance；Second source
(e1) positive terminal and can slide on described long resistance；
The other end of the negative pole end of described second source and described long resistance is added in the two ends of described pressure cell respectively；Institute
State between positive pole and one end of described dew cell that switch is located at described first power supply；First pin of described music module and
Second pin is connected between one end of described adjustable resistance and described switch, the colelctor electrode of three-prong connecting triode, institute
The other end stating adjustable resistance connects the other end of described long resistance；The base stage of described audion also connects the another of described long resistance
One end.
Brief description
Be more fully described the exemplary embodiment of the present invention by referring to accompanying drawing, the above and other aspect of the present invention and
Advantage will become more easily clear, in the accompanying drawings:
Fig. 1 is dew cell annexation schematic diagram of the present invention；
Fig. 2 is the fundamental diagram of the too high automatic control alarm system of humidity of the present invention.
Specific embodiment
Hereinafter, it is more fully described the present invention now with reference to accompanying drawing, various embodiments shown in the drawings.So
And, the present invention can be implemented in many different forms, and should not be construed as limited to embodiment set forth herein.Phase
Instead, these embodiments are provided so that the disclosure will be thoroughly and completely, and fully convey the scope of the present invention to ability
Field technique personnel.
Hereinafter, it is more fully described the exemplary embodiment of the present invention with reference to the accompanying drawings.
As shown in figure 1, dew cell rsResistance r long with one connects in circuit, e0For a power supply.Another power supply e1's
Can slide on resistance r in one end 0, other end is c.When humidity meet require, the voltage drop corresponding to resistance between od with
e1Equal, between cd electric potential difference uvIt is zero.As humidity increase, the voltage drop corresponding to resistance between od and e1Compare relatively low, e1With
Resistance between od and the element between cd constitute loop, there is electric potential difference between cd, and direction is to point to c from d.
As shown in Fig. 2 after switch closure, requiring when humidity meets, the potential u at cd two endsvIt is added in pressure cell ryOn, ry
Resistance be zero, voltage's distribiuting is in adjustable resistance rpTwo ends, audion is in cut-off state, and the warning circuit of music module is not sent out
Go out alarm signal；When humidity raises, the Hall voltage at cd two ends raises, and the resistance of pressure cell tends to infinitely great, rpTwo ends are divided
The voltage obtaining diminishes, and works as ryWhen both end voltage is more than the conduction value of audion, audion is in the conduction state, and music module sends
Alarm sound.
The foregoing is only embodiments of the invention and oneself, be not limited to the present invention.The present invention can have various conjunctions
Suitable change and change.All any modification, equivalent substitution and improvement made within the spirit and principles in the present invention etc., all should
It is included within protection scope of the present invention.
