Specific embodiment
It is started switch currently, the Starting mode netted clearly to electrical equipment is substantially in addition to configure for electrical equipment, Such as it is arranged in pin hole gap and starts switch, or started switch in concealed location setting.Both equipment started switch Mode is provided to that user is avoided accidentally to touch.But the operation that can also start clear net program to user simultaneously is made troubles.In addition, right In the certain electrical equipments for being mounted on specific position, such as suspended ceiling lamp, air-conditioning etc., to control and start switch, it is necessary to use Its peripheral devices is climbed or even is dismantled at family, is further made troubles the operation of user.
Other than above-mentioned control mode, clear net operation can also be started by the way of powering off to electrical equipment. But it is often complex based on the circuit inside electrical equipment, if with the storage such as inductance, capacitor in the circuit of electrical equipment It can element.Such as the controller of control electrical equipment, the alternating current for the 220V that operating voltage is inputted not by power switch Pressure, it is therefore desirable to using the operating voltage for needing 220V voltage modulated to controller by voltage modulation circuit.And this electricity Pressure modulation circuit can make power switch generate time delay to the power-off of controller, if power-off of the power switch to electrical equipment Time is shorter, and controller does not just receive the signal of power-off yet, causes controller that can not start clear net program.
In conclusion control starts the control of clear net program in the case where user is shorter to electrical equipment power-off time Device does not often receive electrical equipment and the signal powered off occurs, or the electric signal for being only deemed as inputting generates of short duration fluctuation; In other words electrical equipment is powered off and reaches the mode for starting clear net program, there is certain want to user's control power-off duration It asks, there is a problem of detecting inaccuracy to power-off signal.In addition, being powered off to electrical equipment and closing to electrical equipment or open again There is also certain similarities for dynamic equal operation, and also then track control unit mistake starts the risk of clear net program to a certain extent.
For this purpose, the clear net device of a kind of electrical equipment provided herein, directly break to power switch in the device Electricity condition is detected, and continues to can be detected too long without power switch power-off time, in addition, only breaking within a preset time Electric number, which reaches preset times, could start clear net program, avoid accidentally touching situation.And power supply is taken full advantage of on this basis The power down function of switch, so that the function of power switch is extended.The clear net device will be carried out with specific embodiment below Detailed description.
In order to enable those skilled in the art to better understand the solution of the present invention, with reference to the accompanying drawings and detailed description The present invention is described in further detail.Obviously, described embodiments are only a part of the embodiments of the present invention, rather than Whole embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise Under every other embodiment obtained, shall fall within the protection scope of the present invention.
3, as shown in FIG. 1, FIG. 1 is the signals of the circuit structure of the clear net device of electrical equipment provided in an embodiment of the present invention Figure, the clear net device may include:
Power failure detection circuit 2 and controller 3;
Wherein, the output end electrical connection of the power switch 1 of the power failure detection circuit 2 and the electrical equipment, for examining Survey the off-position of the supply voltage of 1 output end of power switch;
The controller 3 is connected with the power failure detection circuit 2, for detecting when the power failure detection circuit 2 pre- If power-off number reaches preset times in the period, then start clear net program.
For general electrical equipment, power switch 1 is its essential component.1 one end of power switch connects External power supply 4, the power load 5 of one end connecting circuit equipment are connect, if power switch 1 disconnects, electrical equipment and external electrical Source 4 powers off.
As shown in Figure 1, power failure detection circuit 2 is when user once powers off electrical equipment by power switch 1 An off-position can be detected, and generate corresponding electric signal and be sent to controller 3, controller 3 is according to the power-off received The number of electric signal count cumulative, if cumulative power-off number reaches preset times within a preset period of time, open Move clear net program.
The power down function that power switch 1 is taken full advantage of in the present embodiment is specifically started switch without being in addition arranged, is kept away Exempt from electrical equipment and starts switch the inconvenient problem of control;Power failure detection circuit 2 is directly connected with the output end of power switch 1 It connects, as long as power switch 1 generates power-off, detection circuit 2 can be powered down and detected;And it requires on this basis only default Period interior power-off number reaches preset times and just starts clear net program, can either avoid the operation restarted repeatedly with electrical equipment It is overlapped, and can be avoided user accidentally there are unstable fluctuations to cause for touching or power grid, cause what clear net program surprisingly restarted to ask Topic.
In conclusion clear net device provided herein, sufficiently extension and the power down function using power switch 1, On the basis of the circuit components for simplifying electrical equipment as far as possible, the accuracy of the clear net program starting of electrical equipment ensure that, User is improved to the usage experience of electrical equipment.
For detect 1 off-position of power switch power failure detection circuit 2, can there are many, below with a kind of specific electricity Road is illustrated.As shown in Fig. 2, Fig. 2 is the circuit diagram of power failure detection circuit provided in an embodiment of the present invention, power-off inspection Slowdown monitoring circuit may include:
Zero crossing comparison module, output resistance Ro, discharge capacity Ci, isolation optocoupler OC and switch detection module;
The first input end of zero crossing comparison module is connected with the first output end of power switch 1, the second input terminal and electricity The second output terminal of source switch 1 is connected;The output end of zero crossing comparison module and the first end of output resistance Ro and isolation light The cathode input terminal of coupling OC connects;
The second end of output resistance Ro is connect with the anode input terminal of the first end of discharge capacity Ci and isolation optocoupler OC;
The second end of discharge capacity Ci and the second input terminal of zero crossing comparison module connect;
Zero crossing comparison module is used to carry out zero passage detection to supply voltage, and is discharge capacity Ci in supply voltage zero passage Discharge loop is provided;
If the supply voltage that power switch 1 accesses is DC voltage, the conducting phenomenon mark direct current of isolation optocoupler OC The raw power-off of pressure;If supply voltage is alternating voltage, it is greater than the signal of alternating voltage when the conduction interval time of isolation optocoupler When the period, mark alternating voltage is powered off;
The input terminal of switch detection module is connect with the output end of isolation optocoupler OC, switchs output end and the control of detection module Device 3 processed is connected, and the on-off for exporting isolation optocoupler OC to controller 3 detects signal.
As shown in Fig. 2, in power failure detection circuit provided herein, when the power supply electricity of 1 output end of power switch output Pressure Vin is alternating voltage, and the size of supply voltage Vin is periodically variable.When supply voltage Vin is high level, electric discharge Capacitor Ci is in charged state, and B point voltage is not higher than A point voltage, and the light emitting diode in isolation optocoupler OC is not turned on, and is isolated Phototriode in optocoupler OC is in an off state;
When supply voltage Vin variation is low level, the conducting structure switching of zero crossing comparison module internal circuit, for electric discharge Capacitor Ci provides discharge loop;At this point, B point voltage is higher than A point voltage since discharge capacity Ci both end voltage cannot be mutated, put Capacitor Ci discharges so that isolation optocoupler OC is connected, and the conducting duration of isolation optocoupler OC is electric depending on the electric discharge of discharge capacity Ci The duration of stream.With the cyclically-varying of voltage Vin, when voltage Vin becomes high level again, discharge capacity Ci restores Charged state, isolation optocoupler OC are then still in an off state.
From the foregoing, it will be observed that when the supply voltage Vin that power switch 1 exports is alternating voltage, in alternating voltage period of change, The electric discharge phenomena of discharge capacity Ci only occur once, that is, occur at the time of supply voltage Vin is reduced to a certain extent such as zero passage, Also only conducting is primary by isolation optocoupler OC.So in the case where 1 output end of normal condition, that is, power switch does not power off generation, Isolation optocoupler OC is with the variation of alternating voltage, periodically conducting and disconnection.
Generally, the supply voltage Vin of used exchange is alternating current, signal period 20ms.However, once inputting Voltage Vin open circuit has occurred, affect supply voltage Vin variation continuity, between the conducting that isolation optocoupler OC will certainly be enabled It is greater than originally fixed period of change every the time, thus can determine that open circuit has occurred in supply voltage Vin.
When the supply voltage Vin that power switch 1 inputs is direct current signal, the first end input terminal of zero crossing comparison module is accessed The positive terminal of direct current signal, second end input end grounding.In normal state, supply voltage Vin is constant high level, B point electricity Pressure is not higher than A point voltage, and isolation optocoupler OC is in an off state.And open circuit occurs for the supply voltage Vin once inputted, then is putting Capacitor Ci will carry out primary of short duration discharge process, while primary of short duration conducting phenomenon also occurs in isolation optocoupler OC.As a result, When detecting the conducting phenomenon of isolation optocoupler OC input supply voltage Vin can determine that for the supply voltage Vin of direct current Open circuit has occurred.
It should be noted that either alternating voltage or DC voltage that power switch 1 inputs, in above-mentioned detection process In, since the discharge process of discharge capacity Ci can terminate quickly, the on state of isolation optocoupler OC is moment to complete switching , isolation optocoupler OC is in off state within the most of the time, is not turned on electric current, therefore significantly reduce system function Consumption.
