Abstract
The present invention is an electronic induction type automation switch.It utilizes human body sensing and realizes Push And Release.When nobody was near inductor at ordinary times, the resistance between the field effect transistor drain-source utmost point was less, output low level, and circuit is an ON state.When 1.5 meters of people's distance-sensor, the resistance between the field effect transistor drain-source utmost point increases, and the output high level can trigger the controllable silicon conducting, and circuit is an OFF state, and the delay adjustments time, only carries naturally then.Utilize this switch both to realize the electrical equipment control automation, prolonged appliance life again, saved the energy.
Description
1. this is the automation switch of an electronic induction type.2. it is a multifunction switch that can be widely used in the automatic electronic field.3. along with the progress of science, automatic electronic begins to use in the every field stealthily.But because putting upon the full stretch of the energy will appear in the finiteness of the energy.So, when pursuing automatic electronic, necessarily require to realize energy savings again.Such as this switch, just can realize above-mentioned two conditions simultaneously, and have the effect that prolongs appliance life, saves material or the like concurrently.4. it is that utilization is responded to ripple and realized Push And Release.Circuit theory is as figure.When nobody is near inductor at ordinary times, field effect transistor BG
1The drain-source utmost point between resistance value less, the IC that is connected with source plate
2The pin current potential is higher than
The SCR Triggerless, actuating switch is not an ON state.During near inductor, the induction ripple is added to BG by the line of induction as the people
1Grid on, BG
1By moment pinch off, BG
1Resistance between the drain-source utmost point increases, IC
2Pin current potential step-down (
) 3 pin output high level, triggering the SCR conducting, switch is OFF state and time-delay HR
2C
2At this moment C
2Charging, 3 pin current potentials raise gradually, when being raised to threshold value
The time, 3 pin output low levels, SCR is triggered, and switch is again an ON state.5. this switch is compared with the power down switch of existing simple function, and it had both realized automation, and saves energy has prolonged circuit lifetime again, and has good exploration.
This switch can be made the minimum product of a garden shape, preferably is contained in the box with function of shielding, in order to avoid misoperation.
Claims (1)
