The utility model has the advantages of simple structure, easy manufacture, credible work and unnecessary frequent battery replacing.

Description

The electronic telecontrol alarm

The utility model relates to a kind of electronic telecontrol alarm, particularly a kind ofly carries out improved electronic telecontrol alarm on remote control doorbell basis, belongs to the electric anti-thief device technical field.

At present, though existing electronic telecontrol alarm is a lot, but generally all exist complex structure, shortcoming that cost of manufacture is high, particularly in the signal receiver of existing electronic telecontrol alarm, for the purpose of using reliably, generally all adopt battery as unique power supply, because receiver is in running order for a long time, its battery can exhaust very soon, the necessary running check battery status of user, as untimely replacing, side will lose the effect of alarm, and therefore existing electronic telecontrol alarm is still not ideal in use.

The purpose of this utility model provide a kind of simple in structure, make easily, reliable operation and need not often change the electronic telecontrol alarm of battery.

The utility model is to constitute like this: it is to improve to form on the basis of existing remote control doorbell, it comprises transmitter (1), receiver (2), common remote control doorbell signal transmission circuit IC1 is installed in transmitter (1), common remote control doorbell signal receiving circuit IC2 is housed in receiver (2), and in transmitter (1), be in series with power switch K1 and gauge tap K2 on the direct supply E1 of IC1, the power supply of IC2 input link a in receiver (2), be connected with power of alterating and direct current automatic transfer equipment (3) on the b, on conversion equipment (3), transformer B is housed, duplex is moved K switch, commutation diode D1, D2, luminotron D3, resistance R 1～R3, potentiometer RP, capacitor C 1～C3, triode V, ac power plug CD, relay J and direct supply E, plug CD is connected with the primary coil of B, and on primary coil, also be in series with a switch in the moving K switch of duplex, the secondary coil of B meets D1 and D2 respectively, the secondary coil neutral earthing of B, the negative pole of D2 meets C2, the collector of R1 and V, the negative pole of D1 meets C1, the normally opened contact J-1 of R3 and J, another termination C3 of R3, the emitter of J and V, the base stage of V by R2 and RP after ground connection, normally opened contact J-1 and the normally closed contact J-2 of one termination J of another switch of the moving K switch of duplex, the anode connection terminal a of its another termination IC2, the positive pole of another termination E of J-2, the negative pole of E, C1, C2, the other end of C3 and J and D3 negative pole be ground connection all, and the D3 positive pole meets R1; Gauge tap K2 is made up of fixed touching plate (4), movable flexure strip (5) and spring (6), fixed touching plate (4), movable flexure strip (5) and spring (6) all are installed in the back side of transmitter (1) housing, and spring (6) is connected with movable flexure strip (5), spring (6) movable flexure strip (5) when confined state not contact with fixed touching plate (4), and spring (6) activity flexure strip (5) and fixed touching plate (4) when compressive state disengage.

Because the utility model is to improve to form on the basis of existing remote control doorbell, and that existing remote control doorbell generally all has is simple in structure, reliable operation, cheap characteristics, therefore after adopting technique scheme to improve, the utlity model has simple in structure, make easily, reliable operation and need not often change the advantage of battery.During use, transmitter of the present utility model (1) is fixed on door or the window earlier, at door or window when closing, make the spring (6) of K2 be in compressive state, at this moment movable flexure strip (5) disengages with fixed touching plate (4), receiver (2) is placed on indoor suitable place, and plug CD is connected on the AC power, then K switch is closed, when alternating current, V work, make the relay J action, its normally opened contact J-1 closure, normally closed contact J-2 disconnects, and at this moment alternating current arrives IC2 after the D1 rectification, when AC power has a power failure, V ends, the J outage, and its normally opened contact J-1 disconnects, normally closed contact J-2 closure, thereby automatically standby direct supply E is connected with IC2, when AC power had electricity, power of alterating and direct current automatic transfer equipment (3) cut off direct supply E automatically, recovered the power supply of AC rectification stream again, because direct supply E does not often use, so just do not need often to change battery yet; When the robber opens door or window, the spring of K2 (6) loses compression, thereby movable flexure strip (5) recovers to contact with fixed touching plate (4), transmitter (1) is worked and is sent signal, receiver (2) receives and sends alarm sound behind the signal of transmitter (1) or alerting signal is notified owner, thereby reaches antitheft purpose.
