The specific embodiment
Touch smoke exhaust ventilator controller as shown in Figure 1, place five metal touch key-press 9 of welding on the wiring board 8 in the housing 7, each touch key-press 9 outer leaded light circle 10 that are with, the bottom of leaded light circle 10 has two and is symmetrically arranged breach, the built-in light emitting diode 11 of breach, light emitting diode 11 welding in the circuit board.The sidewall of touch key-press forms step, form the boss that is used with step on the madial wall of leaded light circle, the upper surface of touch key-press protrudes from the upper surface of leaded light circle, after installing like this upper surface of touch key-press is exposed on the household electrical appliances panel, the convenient finger manipulation touch key-press of using.Described touch key-press and light emitting diode are connected in the controller circuitry, controller circuitry is by touch signal treatment circuit 1, display circuit 2, governor circuit 3, load control circuit 4, buzz circuit 5 and power circuit 6 are formed (as shown in Figure 2), the human body sensing voltage signal passes through user's finger touch to the metal touch key-press, through touch signal treatment circuit 1, connect governor circuit 3, governor circuit 3 is according to the signal of touch signal treatment circuit 1, output signal is controlled display circuit 2 respectively, load control circuit 4, buzz circuit 5, power circuit 6 are used for the power supply of each circuit and load and supply with.
As shown in Figure 3-4, touch signal treatment circuit 1 (is example with 1 road touch key-press circuit wherein) is by the metal touch key-press, not gate IC1E, IC1F, resistance R 1, R6, R11, compositions such as capacitor C 1, C14.When user's finger does not contact membrane keyboard, touch key-press is pulled to supply voltage+5V by resistance R 6, therefore after importing not gate IC1F, the output output low level of IC1F, i.e. the just very low level of diode D1, the negative pole of diode D1 is by R1 ground connection (promptly connecing low level), therefore diode D1 ends, capacitor C 1 two ends potential difference is 0V, so the input of not gate IC1E is low level, and promptly the IC1E output is a high level.When user's finger contacts membrane keyboard, the input of IC1F promptly has been injected into induced voltage signal (as the ac voltage signal of 50HZ), because not gate IC1F is a cmos circuit, input impedance is very high, induced voltage signal is sent into IC1F undampedly, output of IC1F output and the identical high-low level signal of input induced voltage frequency, wherein during high level by diode D1 to capacitor C 1 charging, the charge constant τ of electric capacity=RC, because equivalent current-limiting resistance R numerical value is very little in the charge circuit, be R ≈ 0, so capacitor C 1 is charged to high level, when capacitor C 1 was charged to high level, promptly the input of not gate IC1E was a high level, at this moment the output output low level of not gate IC1E.After user's finger leaves touch key-press, the output of not gate IC1F becomes low level, diode D1 answers reverse bias and ends, capacitor C 1 charge stored is released by resistance R 1 rapidly, the input of not gate IC1E becomes low level very soon, this moment, the output of 1C1F became high level again, this procedure declaration when user's touch key-press and not during touch key-press the level of IC1E output change, be that high level is a not touch key-press of user, low level is just touching button for the user, governor circuit 3 is 1 one chip microcomputer (being called for short " single-chip microcomputer "), and whether single-chip microcomputer is discerned the user by the high-low level signal of the output of differentiation IC1E touch key-press.Single-chip microcomputer detects the once level of each button input every 10ms, continuous when detecting to low level 2 times, think user's touch key-press operation, by programming, realization by user's touch key-press to the control logic of controlling each road loaded work piece state, in this example, totally 5 road touch key-press, corresponding respectively illumination (LAMP) key, (HI) at a high speed, middling speed (MID), low speed (LOW) and delay switching-off (TMR_OFF) button, as pressing a LAMP button, single-chip microcomputer is 1 output output high level wherein, this output links to each other with the end of triode Q5 base stage current-limiting resistance R29, and the other end of resistance links to each other with the base stage of triode Q5, and Q5 is the triode of 1 NPN, grounded emitter, one end of collector connecting relay RL4 coil, 1 termination of RL4 coil+9V, triode Q5 conducting this moment, the relay adhesive, control circuit output is because the voltage of lighting load work.Meanwhile; 2 LEDs 1, LED2 being loaded on illumination key light guide circle below in the display circuit 2 light; indicate current illumination functions to be in opening; the resistance R 16, the R17 that are series on LED1, the LED2 are current-limiting resistance; the parallel connection of connecting respectively behind 1 resistance of 2 light emitting diodes can be avoided causing brightness irregularities because of the inconsistent light emitting diode parallel operation of light emitting diode operating voltage; diode D18 is used to the reverse protection diode of LED1, LED2, is used to prevent LED1, LED2 reverse breakdown.When the user touches the illumination button once more, throw light on to export to close, light emitting diode extinguishes thereupon.The positive pole of buzzer BUZ1 connects+the 5V power supply by resistance R 31, negative pole connects the colelctor electrode of triode Q1, Q1 is the NPN triode, its grounded emitter, base stage connects wherein 1 output of single-chip microcomputer by current-limiting resistance R30, when having button operation or other, the user need remind user's the moment, this output output hundreds of millisecond is used for the frequency signal that buzzer takes place, buzzer sound a buzzer one the prompting user, buzzing finishes, this output output low level of single-chip microcomputer, resistance R 31 are used to prevent that triode Q1 overcurrent when driving buzzer from damaging, and can prevent the interference of right+5V power supply.The high speed of motor, middling speed, low speed control principle are the same, repeat no more.The function of delay switching-off button can be according to actual needs when SCM program designs the design function corresponding, as touching once delay time button disable motor and illumination immediately, or touch disable motor and the illumination etc. after 3 minutes of time-delay button.Be used for power circuit 6 to each circuit supply by protective tube FUSE1, safety capacitor C 16, C21～C24, power transformer T1, commutation diode D10～D13, compositions such as mu balanced circuit IC5,220V 50HZ alternating current becomes the 8V low-voltage ac voltage by transformer T1, through diode D10～D13 rectification, capacitor C 21, become the direct current of 9V after the C22 filtering, be used for providing power supply to the coil of relay, simultaneously, the input that+9V DC voltage is gone back mu balanced circuit IC5 links to each other, the common end grounding of IC5, output be exportable stable+the 5V DC voltage, be used for touch signal treatment circuit 1, display circuit 2, governor circuit 3 and buzz circuit 5 power supplies.
