Description
Technical field
Circuit is controlled the present invention relates to a kind of wall touch switch, control wall touch switch control electricity more than particularly single live wire
Road.
Background technology
Wall touch switch and multipath multi-control wall touch switch are controlled single channel dual control, single channel in electronic touch Switch more
Occupy larger ratio in not, can be to user using bringing the convenience of many, but still suffer from during popularization and application many ask
Topic, have impact on the development and popularization of such switch.Control wall touch switch more existing single channel and be essentially relay（KA）Class and
IGCT（SCR）Class soft-touch control, it was found from Current electronic soft-touch control control of product circuit structure and control mode analysis, after
Electrical equipment（KA）Class and IGCT（SCR）Class is not ideal enough.
Relay（KA）The relay coil used in class wall touch switch must during adhesive and maintenance adhesive
Need have certain operating current, due to the load of single channel dual control, many control wall touch switchs be largely low-power LED lamp,
The LED of electricity-saving lamp and fluorescent lamp etc., especially 1W, its operating current is less than the operating current of coil, it is impossible to inhale relay
Close, although the slightly larger light fixture of power can make relay adhesive and keep, the 60% of undertension rated voltage during work, the
Two lamps just can not adhesive.Nominal increase coil resistance can effectively reduce operating current, but for the relay of small package, inhale
Power is difficult to ensure that.Particularly inductance type fluorescent lamp, starter operating current before build-up of luminance is very small, the adhesive of relay coil one,
Electric energy is without supplement, the first storage capacitor repid discharge, circuit automatic clear, it is impossible to normal work, and this is needed the first energy storage electricity
Hold the starter for increasing and selecting quick build-up of luminance, this not only adds volume, cost, trouble is also brought to circuit design.When
So, maximally effective solution is selection twin coil magnetic latching relay, and operating current is equal to zero after adhesive.But this relay
The price of device is 3-5 times of common relay, and user is difficult to receive.
And current IGCT（SCR）Wall touch switch is controlled the single channel dual control of class, single channel more, typically all being compared using function
Powerful single-chip microcomputer, to recognize respective frequencies change and corresponding digital signal after human body touch, this configuration can bring three
Problem：One is that each controlling switch structure is identical, is required to one as the IGCT of main switch and using a list
Piece machine is as control process core, and price is of a relatively high, it is difficult to realize popular；Two be that the static standby current of on-off circuit is up to
More than 60 μ A, glimmer phenomenon occurs in low-power LED lamp, it is impossible to completely close；Three be due to that each controlling switch structure is
Identical, the control signal that each controlling switch is sent must could differentiate by coding, complex circuit designs, therefore use it
Preceding needs are to code, and domestic consumer is often not easy to grasp, using cumbersome, while wiring is also more complicated when installing；Four are
Because the pulse antijamming capability that control signal is used is not high.

Include DC power supply circuit, power drive and on-off circuit, some groups of body capacitance touch detection units and touch output circuit；
The power drive and on-off circuit include the triggers circuit of electronic switch and control electronic switch conducting, the electronic switch string
It is connected in the main circuit of this ON-OFF control circuit；Body capacitance touch detection unit with body capacitance by detecting function, stable state
Constituted for low level monostable circuit, positive pulse letter is exported during the input end capacitor increase of body capacitance touch detection unit
Number；The touch output circuit is made up of bistable circuit, and the touch output circuit input is constituted provided with RC parallel branches
Anti-jamming circuit；The output end of all some groups of body capacitance touch detection units by line or in the way of be commonly connected to
The input for touching output circuit, the output end and the power drive of the touch output circuit and touching for on-off circuit
The triggers circuit of the input connection control electronic switch of Power Generation Road；The DC power supply circuit is power drive and switch electricity
Road, body capacitance touch detection unit and touch output circuit provide DC supply.
Compared with prior art, the present invention is by setting the detection of multigroup body capacitance input circuit and one shared to touch
Output circuit is touched, each controlling switch only needs lineup's body capacitance input circuit to detect, all body capacitance touch detection units
Output end by line or in the way of be commonly connected to the input of the touch output circuit and respectively control to touch output circuit
Output, and then power drive and on-off circuit are controlled, reach the purpose controlled more.During applied to many control wall touch switchs, only
One switch（Master switch）Need to touch inspection comprising DC power supply circuit, power drive and on-off circuit, lineup's body capacitance
Survey unit and touch output circuit, and remaining is switched（From switch）Only need to comprising DC power supply circuit and lineup's body electricity
Hold touch detection unit, material cost is lower, and all the remaining is with line by wire between switch and master switch
Or the mode input of touch output circuit that is commonly connected on master switch be controlled, without the side using coding
Formula differentiates that circuit design is simpler to signal, and the holistic cost of product is greatly lowered.Further, since the present invention takes
Body capacitance input circuit and output circuit is touched in the way of monostable circuit and bistable circuit are combined, and described
Touch output circuit input and be provided with the anti-jamming circuit that RC parallel branches are constituted, the frequency control that will be commonly used in existing more-control switch
