Abstract
The utility model relates to a urination alarm device, in particular to a safe, practical, low power- consumption urination alarm device, which is composed of a sensor, a control portion, and an alarm portion. The utility model has the advantages that: the sensor is two parallel bar-shaped electrodes which are made of conductive rubbers. The control portion is mainly composed of eight bit MCU 78P125. The utility model has the advantages of safety, practicality and low power-consumption.
Description
(1) technical field under
The utility model relates to a kind of urine-wet alarm device, particularly a kind of urine-wet alarm device safe, practical, low in energy consumption.
(2) background technology
Present urine-wet alarm device, its major defect is: 1. its urine wet sensor is that metal forming and rigid insulation material are made, and is dangerous, if expose, stabs user's skin easily.2. its warning system is made by discrete electronic devices and components, and the power consumption height generally uses the family expenses alternating current, uses dangerous.3. poor anti jamming capability causes wrong report easily.
(3) summary of the invention
The utility model provides a kind of urine-wet alarm device safe, practical, low in energy consumption in order to overcome above deficiency.
The utility model is realized by following measure:
Of the present utility model kind of urine-wet alarm device partly is made up of sensor, control section, warning.Its special feature is that described sensor is two parallel strip electrodes, and the material of strip electrode is a conductive rubber.
Urine-wet alarm device of the present utility model, described control section mainly constitutes control module by 8-bit microcontroller 78P156.
Owing to adopt 8-bit microcontroller 78P156 to constitute control module, make total system have little power consumption, safe in utilization and the characteristics of multiple type of alarm are arranged.The logical relation of every control function of single-chip microcomputer is realized by software, has simplified circuit structure, has reduced power consumption, and powered battery easy to use in addition, is controlled every function by software, can carry out the improvement of every function easily.Adopt the delayed alarm mode, effectively eliminated the wrong report that various interference cause.Urine wet sensor adopts the flexible material conductive rubber to constitute, and can not cause actual bodily harm to the user.
The beneficial effects of the utility model are to have advantage safe, practical, low in energy consumption.

(5) embodiment
The urine-wet alarm device of present embodiment partly is made up of sensor, control section, warning.Sensor is two parallel strip electrodes, and the material of strip electrode is a conductive rubber.Control section mainly constitutes control module by 8-bit microcontroller 78P156, and the logical relation of every control function is realized by software, and employing delayed alarm mode, has effectively eliminated the wrong report that various interference cause.
Circuit that the utility model is concrete and control principle are:
This circuit is divided into control and music alarm two parts, constitutes control section by IC1 (single-chip microcomputer 78P156) and peripheral cell, is responsible for urine-wetting signal collection, luminous warning, time-delay control music integrated circuit (IC2) work and adjusts music alarm sound size; Constituting music by music integrated circuit IC2 and main peripheral cell T3, T4 etc. takes place and volume control circuit.
Single-chip microcomputer IC1 (78P156) the 18th pin (PS1) meets urine wet sensor and pull-up resistor R8, and when the wet phenomenon of urine took place, this terminal potential became low level by high level, by software control single-chip microcomputer the 2nd pin (PS3) output pulse, and the luminotron alerting signal that flashes; If do not process this moment, after then delaying time 30 seconds, IC1 the 9th pin becomes high level, T2 conducting, music integrated circuit IC2 power connection, the alerting signal of sounding; When audible alarm began, IC1 control T3 conducting T4 ended, and report to the police for small volume this moment, avoids frightening the user, if this moment, monitoring person did not take measures, and then IC1 control T4 conducting after 15 seconds, the warning volume strengthens, and further reminds monitoring person to come to handle; Any time, push switch S1 makes IC1 the 7th pin (P61) become low level, can stop sound and light alarm; By switch S 2 positions are set, promptly change the level of 12,13 pin (P66, P67) of IC1, the software of IC1 inside solidification can change the output level of the 10th, 11 pin according to the logical relation of setting, and control triode T3, T4 on off state are realized the adjustment of warning volume.
