The utility model discloses Radio-frequency remote control receiving switch with magnetic latching relay, comprising a filter-press filtering unit and at least a group of magnetic latching replies matching with the switch of electrical appliances, wherein the output end of the filter-press filtering unit is provided with a radio frequency receiving module, a digital decode module, a function producing unit and an executive instructive module, the radio frequency receiving module, the digital decode module, the function producing unit and the executive instructive module are electric connected orderly, a trigger switch unit is arranged between the executive instructive module and the magnetic latching relay, and the trigger switch unit can be a silicon controlled rectifier, and can also be a field effect triode, and a current-limit unit is arranged between the magnetic latching relay and the electric network power supply. The radio-frequency remote control receiving switch with magnetic latching relay does not require to storage energy in advance, saving electric energy, moreover, fulfilling the requirement that the over-current protection or earth leakage protection circuit can not wait for delaying, is safe and reliable.
Description
Technical field
The utility model relates to the remote control switch that a kind of remote control lamp, electrical equipment are used, and is a kind of RF remote-controlled receiving key with magnetic latching relay specifically.
Background technology
At present, the RF remote-controlled receiving key of the band magnetic latching relay that common remote control lamp, electrical equipment are used, as long as receive an extraneous pulse signal, the actuating of relay, this state will be memorized, and does not need later on chargedly will keep set state.But in use, it is bigger to promote the required electric current of the pulse signal of magnetic latching relay, and for energy-conservation, generally it is carried out the current limliting power supply in the remote control switch, for this reason, the voltage input end of magnetic latching relay generally also is provided with storage capacitor, promote the actuating of relay with big electric current output behind the capacitance energy storage, therefore, switch must be to electric capacity energy storage in advance, and because the remote control receiving key connects electrical network for a long time, when switch was not worked, circuit still had power consumption, and the supply current when its energy storage is when big, though can shorten energy storage time, the loss of electric energy is just big more.In addition; the remote control switch of this structure; the inverse relation that the reaction time of relay and the size of supply current become to be similar to; the circuit that is used for having overcurrent protection when this type of switch; if waits for too long; overcurrent protective device does not have corresponding effect, burns out power consumption equipment easily, and the actual security reliability of using is relatively poor.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of RF remote-controlled receiving key of saving electric energy, safe and reliable band magnetic latching relay is provided.
Goal of the invention of the present utility model is achieved in that a kind of RF remote-controlled receiving key with magnetic latching relay, comprise voltage regulation filtering unit and at least one group of magnetic latching relay that matches with the electrical appliance switch, the output of voltage regulation filtering unit is provided with Receiver Module, digital decoding module, function generation unit and execution command module, the electrical connection in turn of Receiver Module, digital decoding module, function generation unit and execution command module is characterized in that: be provided with the trigger switch unit between described execution command module and the magnetic latching relay.
Be provided with the current limliting unit between described magnetic latching relay and the electric network source.
Described trigger switch unit is a controllable silicon.
Described trigger switch unit is a fet.
Described current limliting unit is a current-limiting resistance.
Described current limliting unit is made up of current-limiting resistance that is connected in series and diode.
The utility model improves the RF remote-controlled receiving key of the band magnetic latching relay of prior art, make high-voltage switch gear with controllable silicon or fet, magnetic latching relay directly guarantees the action pulse electric current that it is required by electrical network, need not energy storage in switch, saves electric energy greatly.And the remote control switch of this kind structure is swift in motion, and has satisfied the requirement that overcurrent protection or leakage protection circuit can not latency delays, and is safe and reliable.
Description of drawings
Accompanying drawing 1 is the principle schematic of the utility model most preferred embodiment.
Accompanying drawing 2 is the principle schematic of another embodiment of the utility model.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
According to illustrated in figures 1 and 2, the RF remote-controlled receiving key of the utility model band magnetic latching relay, comprise voltage regulation filtering unit 1 and magnetic latching relay 2, the output of voltage regulation filtering unit 1 is provided with Receiver Module 3, digital decoding module 4, function generation unit 5 and execution command module 6, voltage regulation filtering unit 1 power supply to external world carries out after step-down, rectification, voltage stabilizing and the Filtering Processing the power supply of connected correlation module unit, and magnetic latching relay 2 be at least one group and with the use that matches of the K switch of electrical appliance.The electrical connection in turn of Receiver Module 3, digital decoding module 4, function generation unit 5 and execution command module 6, between execution command module 6 and magnetic latching relay 2, be provided with trigger switch unit 7, this trigger switch unit 7 can be controllable silicon, also can be fet, controllable silicon or fet all should be connected use with magnetic latching relay 2 in pairs.Be provided with current limliting unit 8 between magnetic latching relay 2 and the electric network source, when trigger switch unit 7 was controllable silicon, the current limliting unit was a current-limiting resistance 81, as shown in Figure 1; And when trigger switch unit 7 was fet, 8 of current limliting unit were made up of current-limiting resistance 81 that is connected in series and diode 82, as shown in Figure 2.During remote control switch work, magnetic latching relay 2 is simultaneously then by electrical network 8 power supplies through the current limliting unit, during this time, when Receiver Module 3 receives extraneous radio frequency transmissions, each circuit module is handled and is delivered to execution command module 6 in switch, execution command module 6 is sent signal and is made controllable silicon or fet conducting in the trigger switch unit 7, and the break-make control to the electrical appliance K switch is finished in magnetic latching relay 2 actions.The RF remote-controlled receiving key of the utility model band magnetic latching relay need not energy storage in advance, saves electric energy, and, also satisfied the requirement that overcurrent protection or leakage protection circuit can not latency delays, safe and reliable.
