It is below 12V with power supply 102, the resistance value of the 7th resistance 206 is 1K ohms, the 8th resistance 208 and the 9th resistance
209 be 10K ohms, and the capacitance of the first electric capacity 207 is 100uF, and the conducting voltage of the first MOS pipes 204 is 1V, i.e., first is electric
When to hold 207 capacitance cathode voltages be 2V, exemplified by the conducting of the first metal-oxide-semiconductor, the charging complete voltage of final first electric capacity 207 is V1 ginsengs
See formula (2), then the charging interval, discharge time was referring to formula (4) referring to formula (3).
V1=12 × (10K+10K) ÷ (10K+10K+1K)=11.42V (2)
T chargings=1K × 100uF × Ln [(11.42-0) ÷ (11.42-2)]=0.019s (3)
T electric discharge=(10K+10K) × 100uF × Ln [(0-11.42) ÷ (0-2)]=3.48s (4)
It will thus be seen that the charging interval of charge/discharge unit is very fast, therefore when sensor 101 exports high level
So that transmission module 306 rotates.When sensor 101 is not blocked, sensor 101 exports low level, and charge/discharge unit 203 will
After a period of time, when discharging into so that the voltage of C points drops to critical value, it can just cause the shut-off of the first metal-oxide-semiconductor 204, after arriving
Continuous transmission module 306 is inoperative.Therefore the time length of the control signal of Duration Ratio first of the second control signal.Second control
The more durations of the control signal of signal first processed be charge/discharge unit from starting to discharge, drop to critical electricity to C point voltages
The time of pressure.Serve the effect of delays time to control.Those skilled in the art are by the parameter of configuration circuit element according to actual feelings
Condition rationally sets charging interval and discharge time.
A kind of sensor delay control circuit that the utility model embodiment provides, passes through simple sensor, electric capacity, electricity
Resistance, diode, triode and metal-oxide-semiconductor, the stable running of transmission module 306 such as direct current generator, fan, electromagnet is realized,
Successfully realize when sensor 101 is not blocked by barrier, due to the discharge process of charge/discharge unit 203 for some time
It is also possible that the normal table running of transmission module 306, plays a part of delays time to control transmission module 306, whole sensor
Delay control circuit is only with simple electrical equipment, low manufacture cost, and delays time to control effect is simply easily realized.Due to the biography
Sensor delay control circuit does not have the resistance in voltage range and circuit using power supply, exports and is adapted to transmission module 306
The voltage range of access needed for normal operation.
Pay attention to, above are only preferred embodiment of the present utility model and institute's application technology principle.Those skilled in the art's meeting
Understand, the utility model is not limited to specific embodiment described here, can carried out for a person skilled in the art various bright
Aobvious change, readjust and substitute without departing from the scope of protection of the utility model.Therefore, although passing through above example
The utility model is described in further detail, but the utility model is not limited only to above example, is not departing from
