Specific embodiment
As shown in Fig. 1～Fig. 2, this utility model three-wire system switch includes: control chip 1, sensor 2, drive module 3 and
Relay 4.
Wherein, control chip 1 is connected with sensor 2 and drive module 3 respectively, and it is used for controlling cutting of switching relay 4
Move work.
Sensor 2 is used for sensing the movement of human body or object and feedback information delivers to control chip 1.
Drive module 3 is used for driving relay 4.
The control loop of relay 4 is connected with drive module 3, and its switching circuitry has three-line to access and pick out, relay
Device 4 is used for this three-line being turned off or connecting.
Specifically, as shown in Figure 1.This utility model is mainly by control chip 1, sensor 2, drive module 3 and relay 4
Composition.
Wherein, control chip 1 is connected with sensor 2 and drive module 3 respectively；Relay 4 is connected with drive module 3.
Sensor 2 is microwave remote sensor in this embodiment, but not limited to this, its also can with infrared sensor,
Combination of voice operated sensor and multiple sensors etc..When sensor 2 has perceived human body or object in its sensing range
When mobile, feedback information is delivered to control chip 1 by sensor 2, and control chip 1 passes through to control drive module 3 to realize relay 4
The switching of action.Wherein, control chip 1 can achieve the intellectuality to relay 4 according to concrete application environment of the present utility model
Control, such as delays time to control etc..
Multiloop loop system or many complete equipments are started due to needing in many occasions simultaneously or closed.For example exist
In Modern Smart Home life, it is desirable to sensing apparatus are sensing the situation of human body when people are by outdoor entrance room
Under can at once open multiple home equipments, for example open air-conditioning, computer and curtain controller etc. simultaneously.And the said equipment is often each
From having different electric attributes, need to set up controlling switch independent of each other.When extensive popularization above-mentioned smart home design
When, then need substantial amounts of controlling switch, so that build remaining high with maintenance cost.
In the design, relay 4 can be turned off to the three-line with different electric attributes simultaneously or be connected,
So that need occasion multiloop loop system or many complete equipments being started or being closed to be greatly lowered to switch simultaneously
The demand of quantity.
In this utility model, the switching circuitry of relay 4 has wire l1, wire l2 and wire l3 to access and difference respectively
Wire l4, wire l5 and wire l6 is had to pick out.
When do not have in the sensing range of sensor 2 human body or object mobile when, relay 4 will keep wire l1 and lead
The off-state of line l4, keeps the off-state of wire l2 and wire l5, and the off-state keeping wire l3 and wire l6.
When have in the sensing range of sensor 2 human body or object mobile when, wire l1 is connect by relay 4 with wire l4
Logical, wire l2 is connected with wire l5, and wire l3 and wire l6 is connected.
The action of above-mentioned relay 4 is all driven down by drive module 3 and completes.Drive module 3 includes resistance r1, resistance
R2, audion q1, diode d1.Wherein, the base stage of audion q1 is connected with control chip 1 through resistance r1, and audion q1 sends out
Emitter grounding, between the base stage of audion q1 and emitter stage and be connected to resistance r2, the colelctor electrode of audion q1 connects through diode d1
Power supply vcc, diode d1 is in parallel with the control loop of relay 4.
In said structure, resistance r1 is used for limiting the electric current flowing through audion q1, and resistance r2 is used for guaranteeing audion q1 energy
Enough reliably turned off, prevent from disturbing.Audion q1 is used for opening or turning off the electric current flowing through its colelctor electrode.Diode d1 uses
The electric current producing in the moment turning off in the control loop of relay 4 of releasing.
When control chip 1 connect drive module 3 pin send low level in the case of, all do not have in resistance r1 and resistance r2
Electric current is had to flow through, the voltage between the base stage of audion q1 and emitter stage is not up to cut-in voltage, audion q1 is in cut-off shape
State.Between the colelctor electrode of audion q1 and emitter stage, resistance thinks infinitely great, and the colelctor electrode of audion q1 does not have electric current to flow through, therefore
Send into relay 4 without electric current, relay 4 is failure to actuate.
In the case that the pin that control chip 1 connects drive module 3 sends high level, all have in resistance r1 and resistance r2
Electric current flows through, and the voltage between the base stage of audion q1 and emitter stage exceedes its cut-in voltage, and audion q1 turns on.Audion q1
Colelctor electrode and emitter stage between resistance become very little, the colelctor electrode of audion q1 has electric current to flow through, thus have electric current send into continue
Electrical equipment 4, relay 4 action.
Now wire l1 and wire l4 are connected by relay 4, and wire l2 is connected with wire l5, and by wire l3 with lead
Line l6 connects.
When control chip 1 connect drive module 3 pin status be transformed into by high level low level in the case of, resistance r1
With the electric current vanishing in resistance r2, the voltage between the base stage of audion q1 and emitter stage is less than its cut-in voltage, audion
Q1 is turned off.Resistance approach infinity between the colelctor electrode of audion q1 and emitter stage.Because audion q1 colelctor electrode is succeeded
Electrical equipment 4 is inductive load, thus can not be mutated to the electric current of audion q1 colelctor electrode from power supply vcc, and this electric current passes through diode
D1 is released.
Now wire l1 and wire l4 are turned off by relay 4, and wire l2 and wire l5 is turned off, and by wire l3 with lead
Line l6 turns off.
Fig. 2 is the structural representation of relay 4.Relay 4 is provided with the coil 41 as control loop, this coil 41 with
Diode d1 is in parallel.Relay 4 is provided with the switching circuitry for cutting off or connecting multigroup circuit, and this switching circuitry is main
It is made up of sound contact, comprising:
First movable contact 42, this first movable contact 42 is connected with wire l1；
Second movable contact 43, this second movable contact 43 is connected with wire l2；
3rd movable contact 44, the 3rd movable contact 44 is connected with wire l3；
