Abstract
The utility model relates to a remote control burglar alarm, whose proposal is that the remote control burglar alarm comprises an emitter part and a receiver part, and the remote control burglar alarm is characterized in that the emitter is composed of a wireless transceiver IC 1 of a built-in aerial, a power DC 1 and a switch K, the receiver is connected by a wireless transceiver IC 2 of the built-in aerial and is composed of an electronic switch circuit which is composed by a triode T which is connected by a resistance R1 and a alarm circuit which is composed of a resistance R2, an integrated circuit IC 3 (LC179) which is special used for alarming and a high loudness trumpet L. The remote control burglar alarm has advantages of simple structure, convenient manufacture, low manufacture cost and high sensitivity, and the emote control burglar alarm is worth to be popularized and utilized.
Description
Technical field
The utility model relates to a kind of distant control anti-theft alarming device.
Background technology
In bank, important department or family, antitheft extremely important, but robber's theft technology is also more and more higher, existing alarm adopts infrared mostly or vibrations are sensing media, if the robber easily opens the door or drives drawer or proof box and don't cause that then existing alarm will be ineffective when shaking.
Summary of the invention
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of features simple structure, highly sensitive is provided, and the cheap burglar alarm of cost of manufacture.
Its technical scheme is: comprise transmitter and receiver two parts composition, it is characterized in that: transmitter is made up of radio receiving transmitting module IC1, power supply DC1 and the K switch of concealed antenna; Receiver connects the electronic switching circuit of being made up of resistance R 1 connection triode T by the radio receiving transmitting module IC2 of concealed antenna, is made up of the warning circuit that resistance R 2, warning special IC IC3 (LC179) and high loudness loudspeaker L form.
The utlity model has simple in structurely, easy to make, cost of manufacture is low, and highly sensitive, and utilization is worthy to be popularized.
Description of drawings
Accompanying drawing 1 is the structure principle chart of middle transmitter of the present utility model;
Accompanying drawing 2 is structure principle charts of middle receiver of the present utility model;
Among the figure IC1 and IC2 be concealed antenna radio receiving transmitting module (existing product ICM-1A, ICM-1B).
Embodiment
Be further described with regard to its principle of work below in conjunction with accompanying drawing: resistance R 1 connects triode T and forms electronic switching circuit; Resistance R 2 connects warning special IC IC3 (LC179) and high loudness loudspeaker L forms warning circuit.Transmitter is worn on one's body the one of own side, and receiver is installed in the other or safety cabinet of the door that needs etc., and K connects with the unlatching of door.
During 8 meters left and right sides of principle of work: IC1 and IC2 distance, the 2 pin output high level of IC2,3 pin output low levels exceed beyond 8 meters as IC1 and IC2 distance, the 2 pin output low levels of IC2 then, 3 pin output high level;
Close the K switch 1 of transmitter and the power supply DC2 of receiver respectively, K connected after the one of own side opened the door, connect the warning circuit that warning special IC IC3 (LC179) and high loudness loudspeaker L form by resistance R 2, with energized, but because the 3 pin output low levels of IC2, so do not worked by the electronic switching circuit that resistance R 1 connection triode T forms, IC3 can not get triggering and do not work, high loudness loudspeaker L is noiseless.
After the one of own side leaves, when opening the door as the robber, K connects, connect the warning circuit that warning special IC IC3 (LC179) and high loudness loudspeaker L form by resistance R 2, with energized, at this moment because 3 pin of IC2 are exported high level, so connect the electronic switch circuit for working that triode T forms by resistance R 1, IC3 obtains triggering and works, and high loudness loudspeaker L sends alert sound.
Claims (1)
