Embodiment

For making the purpose of this utility model, technical scheme and beneficial effect clearly, below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.Should be appreciated that specific embodiment described herein only for explaining the utility model, instead of limit the utility model.

Fig. 1 is overall structure figure of the present utility model, mainly comprises switch linkage unit 1, supply module unit 2, detection of power loss unit 3, radio-frequency nodes unit 4.After alternating current passes into this switch, two lines can be drawn by switch panel 5 and be connected with group relay changed 6 of below, and supply module unit 2 can process alternating current, for relay 6 and radio-frequency nodes unit 4 after process.Thus can manually console switch panel 5 or receive wireless signal by radio-frequency nodes unit 4 and carry out control relay 6 and carry out switching manipulation, and "on" position can be fed back to radio-frequency nodes unit 4 by detection of power loss unit 3, so just can the switch of control apparatus 7.

Switch linkage unit of the present utility model as shown in Figure 2, comprises the relay 10 of switch panel 9, group conversion.The live wire 8 of alternating current passes into one end of switch panel, and draws two wires from switch panel and be connected with two pins of relay, so namely by the break-make of switch panel control circuit, also can be carried out the break-make of control circuit by control relay.Switch panel chooses common single-pole double-throw switch (SPDT) panel, choosing of relay is then more exquisite, because the power-on surge current that larger all can be had during most electrical equipment start, if general relay, inherently damage the contact of relay, so relay must be selected have the strong relay of Antisurge current ability, can prevent power-on surge current from causing damage to relay like this.

The hardware circuit of supply module unit as shown in Figure 3.Supply module unit is primarily of current rectifying and wave filtering circuit, and change-over circuit, voltage stabilizing circuit is formed.Simultaneously alternating current passes into switch panel and supply module, after supply module passes into alternating current, can by AC rectification and filtering, afterwards direct current is passed to transformer and control chip, after control chip powers on, by ceaselessly switch, carry out the turn-on and turn-off of control transformer primary side, thus produce specific alternating current in primary side, the alternating current of primary side is after over commutation and filtering, power to relay on the one hand, pass to voltage stabilizing circuit on the other hand, the chip that voltage stabilizing circuit adopts is AMS1117, to the burning voltage of 3.3V be produced for radio-frequency nodes after voltage stabilizing.Wherein, no matter be the rectification circuit of primary side or the rectification circuit of primary side, all halfwave rectifier is adopted.Because the frequency of alternating current is lower, therefore the diode IN4007 of slow recovery has been selected in primary side rectification, and primary side due to the frequency of switch chip switch higher, the ac frequency induced is larger, so adopt the fast diode US1D recovered, the voltage that such primary side exports is still more stable.

The hardware circuit of detection of power loss unit as shown in Figure 4.Detection of power loss unit is primarily of current rectifying and wave filtering circuit, current-limiting circuit, optocoupler composition.Whether there is electricity by detecting relay output end, detecting the energising situation of whole circuit.The alternating current of relay output end becomes direct current after rectifying and wave-filtering, because the electric current by optocoupler can not be too large, so must through current limliting, therefore a large resistance has been connected in series in circuit, the primary side of optocoupler is passed into again after large resistance current limliting, simultaneously the primary side of optocoupler is an in parallel relatively little resistance, this resistance is in order to optocoupler primary side when ensureing to power on has certain voltage can make optocoupler conducting.When optocoupler primary side does not have conducting, detecting pin is high level, and when optocoupler luminescence causes primary side conducting, it is low level for detecting pin, and the low height of this level represents the break-make of alternating current, and this signal will feed back to radio-frequency nodes.

The hardware circuit of radio-frequency nodes unit as shown in Figure 5.Radio-frequency nodes forms primarily of microcontroller chip STM8 and radio frequency chip SI4438, and both are by SPI communication.After radio frequency chip receives signal, can pass to microcontroller, microcontroller can send the switch that control signal removes control relay, thus controls the break-make of alternating current.Feedback signal then to be passed to the microcontroller in radio-frequency nodes unit by the break-make of alternating current by power-fail detection circuit, microcontroller is by signal transmission to radio frequency chip, and this signal transmission is gone out by antenna by radio frequency chip.

The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all make in spirit of the present utility model and principle any amendment, equivalently to replace and improvement etc., all should be included in protection range of the present utility model.
