Abstract
The utility model discloses a standby anti-eavesdrop device for a telephone. The device comprises an external human body sensor, a single-chip microcomputer, an incoming call receiving circuit, lamplight, a receiver, a microphone and an electronic switch. The single-chip microcomputer is respectively connected with the incoming call receiving circuit, the lamplight, the receiver and a vibrator of the telephone, simultaneously connected with the sensor, and connected with the microphone through the electronic switch. The standby anti-eavesdrop device for the telephone is provided with the single-chip microcomputer for recognizing rings or the vibrator or the lamplight of incoming call signals and signals of the external phone answering human body sensor. When only tow signals appear at the same time, the single-chip microcomputer connects the microphone into a connected calling state. If only signals of incoming calls appear and nobody answers the phone, or a wiretap method of no ring for the incoming calls appears, the microphone is in a disconnected state. Even other circuits are in a normal working state when the telephone is turned on, no speech information can be sent out, thereby having a reliable standby anti-eavesdrop function.
Description
Technical field
The utility model relates to the Computer Control Technology field, is specifically related to phone standby anti-eavesdrop device.
Background technology
Along with the high speed development of telecommunications industry, home phone number and personal mobile phone are constantly intelligent, and owning amount sharply rises.In using the smart phone process, when tap phone is called in, phone is that No ringing or vibrations or light are bright.If at this moment use old-fashioned smart phone, the circuit of transmitter is communicated with, so, can have no under the situation about discovering owner and eavesdropped.These illegal means are to use wireless device to eavesdrop the bad phenomenon that others talks, and can make country in case succeed, army, and commerce, group and personal user are leaked secret, and national interests and individual privacy have received serious infringement, suffer unnecessary loss.Phone anti-eavesdrop technology in the past is to adopt the encoding and decoding cipher mode to encrypt, and shortcoming is that password is decrypted easily, is not reliable anti-eavesdrop technology.
Summary of the invention
The purpose of the utility model provides a kind of phone standby anti-eavesdrop device, and this apparatus structure is simple, uses telephone set custom control transmitter switch in conjunction with people, reaches the purpose of highly reliable standby anti-eavesdrop.
For realizing above-mentioned purpose, the technical scheme of the utility model is: phone standby anti-eavesdrop device comprises external human inductor, monolithic computer; The incoming call receiving circuit, light, receiver; Transmitter and electronic switch, said monolithic computer are connected with incoming call receiving circuit and light, receiver, electromagnetic shaker respectively, are connected with inductor simultaneously; Be connected with transmitter through electronic switch, described incoming call receiving circuit is connected with receiver.
Described external human inductor is a metal material.
On the described receiver ring is set.
Described electromagnetic shaker is an eccentrically weighted motor.
Described light is semiconductor light-emitting-diode.
Also be provided with hand switch on the described electronic switch.
The utility model phone standby anti-eavesdrop device takes monolithic computer to be connected with external human inductor; So that judge whether external induced signal of making a phone call to produce; Be connected with the phone receiving circuit, having judged whether incoming telephone signal, thereby accurately control the transmitter output.Transmitter is connected with the emission modulation circuit through the anti-eavesdrop electronic switch, and the anti-eavesdrop electronic switch can not connect transmitter yet and connects the circuit of controlling transmitter unit.The utility model has monolithic computer to discern ring or electromagnetic shaker or the light and the external human body inductor signal of answering the call of the signal of calling automatically; With the human-induced signal is main; When having only two signals to occur simultaneously, but monolithic computer connects the talking state into conducting with transmitter, the eavesdropping mode of No ringing if the signal no one who only calls answers the call or calls; Transmitter is for disconnecting state; Even remaining circuit is in normal start operating state, also can't any voice messaging be sent, thereby play reliable standby anti-eavesdrop function.
Description of drawings
Accompanying drawing 1 connects schematic block diagram for the utility model.
