Description
Affiliated technical field
The utility model relates to a kind of intelligent radio remote control switch device.
Technical background
" intelligent radio remote control switch " is the inexorable trend that development is used in electric lights such as modern house, office space, electrical control.Each big electric manufacturer is is all competitively actively researching and developing its series of products.But existing electronic switch majority adopts active devices (field effect transistor or controllable silicon etc.) as switching device, serious, the poor stability of its load capacity poor (general one tunnel load can only reach 200 watts) and heating; If adopt passive step-down or active pulse power-supply circuit, exist then that heating is serious, circuit is complicated, work is unreliable, power supply quality is poor, easily to shortcomings such as CPU and wireless receiving circuit generation interference.
Summary of the invention
The purpose of this utility model is that a kind of intelligent radio remote control switch device will be provided, and this device does not only have High-frequency Interference, and good energy-conserving effect.
The utility model is to constitute like this, it comprises remote controller and has power-supply circuit, the electronic switching circuit of wireless receiving module and relay switching circuit, it is characterized in that: (1) has the power-supply circuit of live wire power getting unit and switch closure power taking unit, for the live wire that exchanges 220 volts is received through just, oppositely mutually and an end of the diode that connects, just, oppositely mutually and the other end of the diode that connects receive the ac input end of a rectifier bridge again, another ac input end of rectifier bridge is received an end of capacitor C, the other end of capacitor C arrives the zero line of 220 volts of interchanges through a load such as bulb, load and an electric capacity are in parallel, (2) in the switch closure power taking unit just, the diode that oppositely joins also connects a step-up transformer, boost current produces the output of two-way direct voltage after rectification, be made for the power supply of wireless receiving module and relay switching circuit, one end of the relay normally open contact of relay switching circuit connects load, the other end is connected in two power taking unit, (3) output of the rectifier bridge in the live wire power getting unit connects two voltage-stabiliser tube output two-way direct voltages that are in series, and, be made for the working power of electronic switching circuit by the corresponding output in parallel in live wire power getting unit with the two-way direct voltage that produces by switch closure power taking unit.
The utility model is in the control switch of " live wire " that enter switch enclosure and first via load between (number of switches of this patent design can by one to a plurality of), some two power-supply circuits forming by passive device have been sealed in: " the live wire power getting unit 9 " formed by forward and reverse phase and the diode circuit that connects and step-up transformer in parallel with it, " switch closure power taking unit 10 " by capacitor C and bridge rectifier are formed provides working power for other circuit respectively under closure and open circuit situation.Its operation principle is such: as shown in the figure, when relay switch 1 is not closed, load 5 bulbs are not bright, at this moment power taking process is that power firestreak 11 warp " live wire power getting unit 9 ", " switch closure power taking unit 10 ", load 5 constitute the closed-loop path with civil power 220V, flow through less current in the loop, make " switch closure power taking unit " obtain direct current, through voltage-stabiliser tube W1, W2 supply with respectively+17.6V and+DC power supply of 5.6V; When relay switch K1 is closed, load 5 bulbs are lighted, " switch closure power taking unit 10 " exported by the short circuit non-transformer, during diode but load current is flowed through in " live wire power getting unit 9 ", produced 1～2 volt voltage drop, after small transformers in parallel with it boosts rectification, provide equally+17.6V and+the DC power supply power supply of 5.6V, and connect together with the output of " switch closure power taking unit 10 ", kept normal power supply.Because two power-supply circuits of this patent design have all been selected passive device for use, its reliable working performance, stable, and out-put supply is pure, can not produce interference to CPU14 and wireless receiving module 15.In this patent circuit, also have two critical elements, the first is attempted by the Transient Suppression Diode D1 of bridge rectifier diode output in " live wire power getting unit 9 ", its function is the heavy-current discharge of absorption of K 1 closure moment capacitor C, if there is not D1, the big electric current of C sparks and will be easy to damage voltage stabilizing didoe W1 and W2.Certainly, other has a circuit design is the relay that relay switch 1 is selected two-way contact for use, can save Transient Suppression Diode D1, and this local circuit is also as the accessory circuit of this patent circuit.It two is the capacitor C ' that are attempted by the load two ends because load 5 is if not during the ohmic load of incandescent lamp and so on (as electronic energy-saving lamp), " live wire power getting unit 9 " will not have Weak current to flow through and get less than.Add capacitor C ' then just there have not been these problems.
Than existing intelligent radio remote control switch device, the utlity model has following remarkable advantage:
What (1) power-supply circuit of this patent adopted is passive component, does not therefore have High-frequency Interference.
(2) power-supply circuit of this patent has " live wire power getting unit " and " switch closure power taking unit " two parts to form, and the control by relay contact reaches energy-conservation effect.
(3) relay switching circuit of this patent has adopted the power saving design, only in the time of relay adhesive high power supply power supply is arranged, in case just become the power supply power supply of low-voltage after the relay adhesive automatically, thus reach purpose of power saving.
