Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
System construction drawing of the invention as shown in Figure 1, a kind of squatting pan auto-flushing paper extraction system on the whole by detection system
System, master control system and drive system composition.Detection system is made of infrared sensor and laser sensor.Infrared sensor is used to
Detect whether that someone goes to the toilet, laser sensor is for detecting whether paper extraction is finished.Nobody enters induction zone, and indicator light goes out；
When someone enters induction zone, indicator light is bright.When detecting that paper has been used up, then low paper indicator is bright.Master control system by
STM32F103ZET6 single-chip minimum system and power supply system composition, are the control cores of whole system.Drive system is for driving
Dynamic voice module and stepper motor, realize system voice broadcast and automatic paper extraction function.When someone enters induction zone, voice
System plays music or public service ads automatically, and paper extraction system completes automatic paper extraction under the drive of stepper motor.Relay module
For controlling the on and off of solenoid valve, to realize the function of auto-flushing.
Infrared sensor interface circuit of the invention is as shown in Fig. 2, the receiver SM0038 of infrared sensor is a one
The infrared remote control receiver of body, externally only 3 pins, pin 1 connect 12 volts of power supplys, and pin 2 is connected to by divider resistance R4
The port PG.15 of single-chip microcontroller, pin 3 are grounded.When someone enters induction range, infrared sensor will detect human body generation
Infra-red radiation, the signal of receiving end pin 2 becomes low level, and indicator light is bright；If nobody enters induction zone, indicator light off.
Laser sensor interface circuit of the invention as shown in figure 3, laser detection by Laser emission and laser pick-off module
Composition, judges whether there is paper by the way that whether laser detection receiving module receives laser.When lacking paper, laser sensor is not examined
Barrier is measured, then No. 2 pins are high level, are sent to control system, light low paper indicator by single-chip microcontroller.When there is paper, 2
Number pin is low level, and single-chip microcontroller control instructions lamp does not work.
The design of automatic flushing system circuit of the invention as shown in figure 4, automatic flushing system using electromagnetism relay
Device goes to control biggish electric current, higher voltage with lesser electric current, lower voltage as control circuit, realization.Described
Port PC3 connection resistance R12, the base stage of resistance R12 the connection R10 and triode Q1, the collector of the triode
Diode D5 and relay are connected, the transistor emitter connects power supply, is connected with rank above the electromagnetic relay
Iron, the green terminal base connection photodiode and R6.
The automatic flushing system controls solenoid valve by relay to control water yield and water discharging time.Solenoid valve
There is closed chamber in the inside, and through-hole is provided on different location, respectively connects different water pipes.The centre of chamber is piston, and two sides is electricity
Magnet.Electromagnet can generate magnetic attraction valve body after being powered, and solenoid valve is exactly that different drainings are controlled by the movement of valve body
The opening and closing in hole.Inlet opening be it is normally opened, water enters different drainpipes by inlet opening, and the pressure of water pushes water vat
Piston, piston driving piston rod, piston rod drive mechanical device, realize auto-flushing.
The stepping motor interface circuit that automatic paper extraction driving circuit of the invention uses is as shown in figure 5, the THB7128 used
Driving chip drives stepper motor to rotate one by the direction of setting after driving chip receives a pulse signal
Fixed angle, the rotation of stepper motor are carried out step by step with fixed angle, and the control of angular displacement is to pass through control
What the number of pulse processed was realized.Can control user to take the length of paper by stepper motor is every time 25 centimetres, reach saving paper,
Avoid the purpose of waste.
Voice broadcast circuit of the invention is using WT5001 voice module interface circuit as shown in fig. 6, WT5001-
48L is the MP3 speech chip of a OTP high tone quality, possesses 8-bit CISC, supports WAV and MP3 decoding；Peripheral hardware
Rich interface；One SPI supports DMA；16 ohm of earphones can be directly driven；Band real-time clock and permanent calendar function；Standard
RS232 serial ports control function；It is low in energy consumption, about 80 uA of standby current when suspend mode；Control plays response speed and is better than similar product；
It is applicable to the occasion for replacing voice or the music file time is longer, sound quality is more demanding[6].Included SPI-FLASH storage
Medium carries one watt of power amplifier；It download online music file or TF card or U disk can be passed through replaces music file.Voice is broadcast
The function of reporting module is to play music or public service ads automatically when infrared sensor detects that someone enters induction zone；Nobody
When, stop playing music.
Algorithm flow chart of the invention is as shown in fig. 7, system is based on Keil u Vision5 too development, with C voice work
For development language.Whole system software includes infrared detection module, fingerprint identification module, laser detection module, single chip control module, auto-flushing
Drive module, automatic paper extraction module and voice broadcast module.Firstly, detecting whether that someone enters by infrared sensor, will test
As a result it is sent to single-chip microcontroller.If someone enters, music is played by MCU driving voice broadcast module；It can be suspended by key
Play or switch song.MCU driving automatic flushing system works once at regular intervals.Postponing certain time, (program is set
It is fixed) after, it is detected by laser sensor either with or without paper, will test result and be sent to single-chip microcontroller.When without paper, lighted by single-chip microcontroller scarce
Paper indicator light；There is paper, then after people presses paper extraction key, certain length (25 centimetres) are released by MCU driving stepper motor
Paper.If infrared sensor detects nobody, analyze and determine previously whether someone if someone stops music and broadcasts by single-chip microcontroller
It puts, and is washed by water by MCU driving solenoid valve, closed after a certain period of time.It is used by software realization squatting pan unmanned
It does not wash by water when being used with someone, only postpone certain time (5 seconds) functions of washing by water after people leaves；Realize that people goes to the toilet
When, the function of the automatic paper for extracting equal length out.
System of the invention is in kind as shown in figure 8, whether meeting design requirement for each module performance of verifying system, to system
It is repeatedly tested, the table that obtains that test result is as follows.
Each module testing result of 1 system of table and test result
