It is single, small power consumption, convenient for universal in large-scale public lavatory.Entire alert device, also has the characteristics that hommization.
As shown in Figure 1, U1, U2 are external excuse, external pressure sensor, power supply B1 is supplied to external pressure sensor
Electricity, resistance R1 are current-limiting resistance, prevent from, because supply voltage is excessive, causing circuital current, voltage excessive, to burn out pressure sensing
Device and microcontroller.K1 is flush button, and the effect of power supply B2 is that electric current, voltage signal are generated when K1 is connected, and is sent into microcontroller
In, resistance R2 is current-limiting resistance.The circuit to connect with XTAL1, XTAL2, RST is to play seismoelectric road necessary to microcontroller work.
Microcontroller is powered by start-oscillation circuit, and display screen is powered by microcontroller.The constituted circuit of B1, R1, pressure sensor is pressure sensing
Circuit（It is located under closet people's foot standing place）, the constituted circuit K1, B2, R2 is circuit of washing by water in door（It is located at chamber pot flushing water
At button）.U3 is external interface, external ventilation fan, and V1, V2 are external power supply, and power supply V1 is start-oscillation circuit external power supply, power supply
V2 powers to ventilation fan.Inductance L1 and switch K3 constitutes electromagnetic valve inside flushing toiler, and inductance L1 and switch K4 constitute control
The electromagnetic switch of ventilation fan work.
Detailed process describes：When people goes to toilet, on pressure sensor, force-sensing resistor reduces people's foot, is sent into
Signal increases in microcontroller, and microcontroller control LCD display LCD1 shows " paying attention to bath after an action of the bowels " prompt, is pressed after upper complete lavatory
Force snesor does not have microcontroller still control display screen when pressure to work a period of time, i.e. LCD display late release time（It has gone up
Lavatory would generally first leave pressure sensor position and flush the toilet again）, when pressing flush button K1, bath circuit generates telecommunications
Number and be sent into microcontroller, single chip machine controlling circuit shows " you washed by water prompt ", while microcontroller exports high level, inductance L1
Voltage, which increases, generates magnetic field, and switch K3, K4 are closed under magnetic fields, and electromagnetic valve is closed inside flushing toiler, closestool release
Detergent, ventilation fan circuit are connected, ventilation fan work, after microcontroller controls the LCD display late release time, microcontroller
It controls LCD display to close, no longer by magnetic fields, switch K3, K4 disconnection, ventilation fan is stopped by switch K3, K4.
Reset circuit of SCM：To ensure the circuit stability reliably working in systems of microcontroller 2, reset circuit is must can not
First function of a few part, reset circuit is electrification reset, and since 2 circuit of microcontroller is sequential digital circuit, it is needed
Stable clock signal, in power supply electrifying, only when VCC is more than that 4.75V is less than 5.25V and crystal oscillator steady operation
When, reset signal is just removed, and circuit starts to work normally.Therefore it needs to reset in microcontroller RST and connects an electricity on input pin
Hold to the ends Vcc, under connect a resistance to.
Singlechip clock oscillating circuit：In the system of multiple chips composition, in order to which the clock signal between each chip is same
XTAL1, frequently with external clock mode, i.e., is grounded by step, and external crystal oscillator and capacitance composition oscillator access XTAL1 and XTAL2.
Above in association with attached drawing, the specific embodiments of the present invention are described in detail, but the utility model is not
It is limited to the above embodiment, within the knowledge of a person skilled in the art, this practicality can also be not being departed from
Various changes can be made under the premise of novel objective.
