Description

Micro Energy Lose intelligence bed-wetting alarm device

Technical field

This utility model relates to a kind of Micro Energy Lose intelligence bed-wetting alarm device.

Background technology

Society steps into aging society now, and the open two tire policies of country, the old man making each family is doubled with child, and owing to old man can cause the bed-wetting phenomenon that sleeping at night can not get up in the night to urinate in time after ill, and easily cause with Body contact after urine soaks bedding as you know and contact skin allergy and inflammation, make the matter worse to ill old people, how nursing staff could can change bedding for old man timely and become a social difficult problem after old people wets the bed.

Summary of the invention

The purpose of this utility model is to provide a kind of Micro Energy Lose intelligence bed-wetting alarm device, utilizes the programme-control of single-chip microcomputer can receive urine-wetting signal in time, power consumption less, alarm sound crescendo, easy to use, can get help in time, from the hardship of immersion.

Above-mentioned purpose is realized by following technical scheme:

A kind of Micro Energy Lose intelligence bed-wetting alarm device, its composition includes: electric wire 2, one end of described electric wire 2 connects base stage b of NPN type triode Q3, the other end of described electric wire 2 connects the probe of humidity sensor RV1, described NPN type triode Q3 loads warning box 3, warning circuit is had in described warning box 3, described circuit for alarming plate includes single-chip microcomputer U1, the P3.1 pin of described single-chip microcomputer U1 connects one end of resistance R8, the other end of described resistance R8 connects base stage b of PNP type triode Q2, the colelctor electrode c of described PNP type triode Q2 connects one end of buzzer LS1, the other end ground connection of described buzzer LS1；

The P3.2 pin connecting valve button S4 of described single-chip microcomputer U1；

One end of the colelctor electrode c and resistance R11 of P3.3 pins in parallel NPN type triode Q3 of described single-chip microcomputer U1, the other end connecting luminous diode D2 of described resistance R11, the emitter e ground connection of described NPN type triode Q3, base stage b of described NPN type triode Q3 connects humidity sensor RV1.

The P3.5 pin of described single-chip microcomputer U1 connects one end of resistance R9, the other end connecting luminous diode D1 of described resistance R9.

Described Micro Energy Lose intelligence bed-wetting alarm device, described switch key S4 is arranged on bed 1 limit.

Beneficial effect:

Sensor circuit part the most of the present utility model power consumption when not having signal goes to zero, and reduces energy consumption.

Single chip part the most of the present utility model takes full advantage of power down arousal function, and when not having input signal, single-chip microcomputer is in power down operations pattern, and operating current is less than one microampere, and power consumption goes to zero.

3. this utility model is owing to introducing single-chip microcomputer, enormously simplify hardware components, reduce rate of false alarm, audible alarm mode is more intimate, such as warning volume is similar to alarm clock on cell phone wake-up mode crescendo, tonequality, tone are the most able to programme, reduce to greatest extent and bother periphery personnel's sleep in the dead of night when；Fundamentally having stopped that the tinkle of bells is little not to be heard, the tinkle of bells is big may be the loftiest, and user causes the situation of scaring.

4. this utility model is in the case of hardware circuit is constant, by programming, can realize old man and urinate wet call service (urinate wet rear delayed alarm, after nursing staff hears warning, can the most more changing babies' napkin)；Preventing child is wet the bed (a little urinating wet horse back to report to the police, prompting child get up toilet), and baby's urinating is it is contemplated that only light warning, it is to avoid child causes the functions such as scaring.

Accompanying drawing illustrates:

Accompanying drawing 1 is circuit theory diagrams of the present utility model.

Accompanying drawing 2 is structural representation of the present utility model.

Detailed description of the invention:

Embodiment 1

Embodiment 2

Micro Energy Lose intelligence bed-wetting alarm device described in embodiment 1, described switch key S4 is arranged on bed 1 limit.Facilitate old man just to stretch out one's hand can get at, it is also possible to being used as calling set by this utility model, a tractor serves several purposes, the scope of application is more extensive.

When there being urine-wetting signal, LED light is bright, and meanwhile, output low level is to single-chip microcomputer, and single-chip microcomputer exports audible ringing signal after being identified signal.This signal can be according to user requirement, instant output or time delay output, and warning volume is gone forward one by one the functions such as enhancing；When single-chip microcomputer receives call signal, drive buzzer output acoustical signal.

Sensor section

(1) urine wet sensor part composition.

RV1 is humidity sensor, and when not having urine-wetting signal, RV1 resistance is infinitely great, and audion Q3 ends, and D2 display lamp goes out, and now base stage leakage current ICEO is microampere order, and power consumption goes to zero.

When there being urine-wetting signal, RV1 resistance diminishes, audion Q3 saturation conduction, the bright warning of D2 display lamp, and is exported to single-chip microcomputer by P3.3 pin.

(2) call button

When user calls, press switch, by P3.2 pin output low level to single-chip microcomputer, by single-chip microcomputer identification and export tone calling signal.

(3) single-chip microcomputer selects STC series (preferably STCL1001W), 8 foot dual-in-line package；When having warning or during call signal, the verity of signal can be verified (avoiding wrong report), after send audible ringing signal again.

Fully take into account old man's duration reason when urinating, this utility model can also by programming realization urinate wet after delayed alarm, estimate duration of urinating, thus can directly change bedding when nursing staff arrives old man's bedside, it is not necessary to wait.

For child's user, for the custom of getting up in the night to urinate formed, make child's user be issued by alarm sound when just starting and urinating and go toilet to wake up child up.

Loading display lamp in having indicator lamp hole and buzzer hole, described indicator lamp hole on warning box, when utility model works, display lamp separated in time flashes, it is ensured that one can see that it is normal operating conditions.

Certainly; described above is not to restriction of the present utility model; this utility model is also not limited to the example above, change that those skilled in the art are made in essential scope of the present utility model, retrofits, adds or replaces, and also should belong to protection domain of the present utility model.
