Additionally, the electrical block diagram of the simplification of device controller in the embodiment of the present invention can be such as Figure 49Shown in circuit in middle dotted line frame.

Below each signal shown in Figure 49 is illustrated:

A, zero passage detection signal: the necessary signal of controllable silicon light modulation, only need not during switch bulb.

B, signal light control success feedback signal: this signal normality in the case of bulb is non-lit up is high level,When, after the instruction performing headlamp switch, controllable silicon outfan becomes with this signal of circuit onset of civil power zero line compositionFor low level.If after performing headlamp switch signal instruction, this signal, without low level output, i.e. can determine whetherGhyristor circuit has damage；If this signal has low level output, but bulb does not works and i.e. can determine whether that bulb isDamage.

C, SCR control signal: control unit output signal, it is achieved headlamp switch, dimming function.

D, mechanical switch actuating signal: this signal normality in the case of bulb is non-lit up is high level, when pressingAfter lower 86 box switches, this signal becomes low level, can notify that control unit needs and light bulb action(only switching, without dimming function).

E, relay control signal: this signal is used for headlamp switch function and protecting, when light control terminal electricityThis signal should be set to high level after connecting by source as early as possible, and the live wire that 86 box switches come directly is disconnected, nowThe control of light is actually got through bulb Firewire link by controllable silicon；When control unit Signal Fail, circuitPlate powers down or receive control unit require without situations such as SCR control signals time, relayThe default mode that automatic or controlled entrance inactivity requires, is now only capable of the switch with 86 boxes and carries out bulbSwitch motion, but now can lose the functions such as signal feedback, long-range control.

Additionally, for the relay shown in Figure 49, this relay by default, the 3rd foot and the 5thFoot is connected；After requiring the actuating of relay, the 3rd foot of relay and the 4th foot are connected.Additionally, work as relayWhen device is in state after action, if now power-supply system breaks down, relay can automatically switch to acquiescenceState.

First below by the work when mechanical switch directly controls of the said equipment controller shown in Figure 50Flow process illustrates, and then utilizes the said equipment controller shown in Figure 51 at home control terminal (such as handsMachine, panel computer etc.) workflow when being controlled illustrates；

In Figure 50, wall surface switch (namely the mechanical switch in above-mentioned) the control process of light is divided intoUnder several stages:

First stage: after whole light units wiring completes and powers on, first thing after control unit operationFeelings require the actuating of relay exactly, and relay output end (the 3rd foot) is received the unsettled pin (of relay4 feet), hereafter whether the opening and closing movement of wall surface switch is just energized without direct relation with bulb.Certainly list is controlledUnit requires that the signal of the actuating of relay is treated, if now control unit fails normally to work, and shouldDeficiency so that the actuating of relay, but is allowed relay be operated in default conditions by signal, i.e. relay output pin(the 3rd foot) is joined directly together with input pin (the 5th foot), and hereafter the opening and closing movement of wall surface switch is the most directly ledLead to bulb and process without control unit.

Second stage: the opening and closing movement of wall surface switch provides actuating signal, real 220V for control unitPower output is silicon controlled action.Illustrate the most whole control flow: after wall surface switch is pressedA point is energized, and after the process of U2, mechanical switch actuating signal can become from 0 level signal of normality1 level signal.After this 1 level signal being detected, control unit is it is thought that signal of turning on light, immediatelyBulb is made to light controlled silicon conducting by SCR control signal.When control unit sends conducting silicon controlledAfter order, detect that B point has 1 level signal, then it is assumed that control the most successful.

Phase III: after control unit sends conducting silicon controlled order, being not detected by B point has 1 electricityOrdinary mail number, then it is assumed that control unsuccessfully, and in product, subelement has damaged.Prolong through suitable MillisecondShi Houruo is also not detected by 1 level signal of B, and control unit can allow relay be operated in default conditions, i.e.Relay output pin (the 3rd foot) is joined directly together with input pin (the 5th foot), allows wall surface switch directly controlBulb.

Therefore when user's folding wall surface switch when, it may appear that four kinds of situations:

Situation 1: bulb normally shows and has feedback of status on the remote equipment such as flat board, mobile phone, then it is believed thatWhole equipment is working properly.

Situation 2: bulb normally show but on the remote equipment such as flat board, mobile phone stateless feedback, then it is believed thatEnvironment division disabler.

Situation 3: bulb the most normally shows but has feedback of status on the remote equipment such as flat board, mobile phone, then can recognizeDamage for bulb.

Situation 4: bulb the most normally shows and stateless feedback on the remote equipment such as flat board, mobile phone, then can recognizeDamage for bulb and equipment.

The device controller provided in the embodiment of the present invention can pass through WIFI and other devices interconnect, because ofThis available such as electronic equipment such as flat board, mobile phone installs corresponding application program and the communication of this product.It is excellentPoint is that in user's WIFI signal can cover region need not directly contact wall surface switch can set lightFor being controlled.

In Figure 51, by electronic equipment the control process of light is divided into following several stages:

First stage: with the wall surface switch in Figure 50 the first stage of the control of light equally belonged to and originally setThe automatic metamorphosis stage of preparation controller.

Second stage: facility registration stage, if user needs to utilize electronic equipment to be controlled light,So need to use WIFI wireless communication technique, this device controller employs the WPS skill of WIFIArt, a light key can be achieved with the pairing of equipment in specific WIFI network.

Phase III: user utilizes electronic equipment to control the light stage, and user passes through application program, to lightTerminal transmitting control commands.After light terminal receives control command, performed by SCR control signalThis order.After this order performs, whether control unit detection B point has corresponding signal to produce to judge that control isNo success.If having obtained the feedback signal turned off the light, user can see lighting of light on application program,Meanwhile it can be seen that the change of light in actual environment.If there being correct feedback on application program, butActual environment is not seen lighting of light, then can determine whether that bulb has damaged.

Fourth stage: if after light terminal performs action of turning on light and be not detected by B point and have 1 level signal,Then judgment part circuit is by damaging, and now relay can be reset to default conditions by light terminal automatically.HereafterOn the premise of being changed without equipment, user remains to continue to be controlled light with wall surface switch.

The device controller provided in the embodiment of the present invention has the advantage that

1, on the premise of being changed without the metope mechanical switch that user's family is traditional, it is achieved utilize flat board, handsThe electronic equipments such as machine carry out instant switch, dim and plan to control the light units of family, and notChange function and the feel of conventional mechanical switch.

2, for comparing the equipment of the popular touch control light in current market, the embodiment of the present invention providesDevice controller have after device controller interior section component wear still can be by metope machinerySwitch the advantage of the on-off control to light.

3, the device controller owing to providing in the embodiment of the present invention achieves the contact control of mechanical switchWith flat board, mobile phone, the Untouched control of apparatus such as computer, therefore the crowd of different age group is all suitable for.

4, user can also be helped while realizing signal light control to detect bulb the most to damage, it is achieved equipmentMaximized for user's service.

Obviously, those skilled in the art can carry out various change and modification without deviating from this to the present inventionBright spirit and scope.So, if the present invention these amendment and modification belong to the claims in the present invention andWithin the scope of its equivalent technologies, then the present invention is also intended to comprise these change and modification.
