Abstract
The invention discloses an electronic anti-theft alarm, which comprises a battery, resistors from a first to a third, capacitors from a first to a third, a diode, a voltage regulator tube, a time-base integrated chip, a microwave induction chip, a thyristor and a loudspeaker. In comparison with the prior art, whether a human body passes is induced via the microwave induction chip; when a person is detected in a range, a control signal is sent to a time delay circuit formed by the time-base integrated chip, a fourth resistor and the third capacitor, the time delay circuit outputs high level to the control end of the thyristor, the thyristor is conducted, and the loudspeaker is connected to give an alarm sound. The electronic anti-theft alarm can be hidden in a secret place, mechanical triggering is not needed, the electronic anti-theft alarm can also be hidden in a wall body and can be prevented from being found out by an illegal person, the feasibility is high, and the promotion value and the use value are provided.
Description
Technical field
The present invention relates to a kind of anti-theft device, particularly relate to a kind of electronic anti-theft alarm.
Background technology
Guard against theft and alarm system is by physical method or electronic technology, automatically detects and occurs in the intrusion behavior deployed troops on garrison duty in monitored area, produces alarm signal, and points out operator on duty that the region portion reported to the police occurs, and display is likely to the system taken some countermeasures.But burglar alarm of the prior art is all mounted in daylight can be implemented, infrared ray, sound, vibrations etc. sense, and are required for being arranged on daylight, it is easy to be found and destroy, accordingly, there exist room for improvement.
Summary of the invention
The purpose of the present invention is that provides a kind of electronic anti-theft alarm to solve the problems referred to above.
The present invention is achieved through the following technical solutions above-mentioned purpose:
nullThe present invention includes battery、First resistance is to the 3rd resistance、First electric capacity is to the 3rd electric capacity、Diode、Stabilivolt、Time base integrated chip、Microwave induced chip、Controllable silicon and speaker，The positive pole of described battery simultaneously with the first end of described first resistance、First end of described first electric capacity、First end of described speaker connects，The negative pole of described battery simultaneously with described silicon controlled the first end、The positive pole of described stabilivolt、First end of described second electric capacity、The negative pole of base integrated chip time described、First end of described 3rd electric capacity and the negative pole of described microwave induced chip connect，Second end of described first electric capacity simultaneously with the second end of described first resistance、The positive pole of described diode and the negative pole of described stabilivolt connect，The negative pole of described diode simultaneously with the second end of described second electric capacity、The reset terminal of base integrated chip time described、The positive pole of base integrated chip time described、First end of described 3rd resistance and the positive pole of described microwave induced chip connect，The signal output part of described microwave induced chip simultaneously with the second end of described 3rd resistance、Second end of described 3rd electric capacity and described time base integrated chip input connect，Time described, the outfan of base integrated chip is connected with the first end of described second resistance，Second end of described second resistance controls end with described silicon controlled and is connected，Described silicon controlled the second end is connected with the second end of described speaker.
The beneficial effects of the present invention is:
The present invention is a kind of electronic anti-theft alarm, compared with prior art, the present invention is by whether the sensing of microwave induced chip has human body to pass through, when detect have people in scope time, to by time base integrated chip and the delay circuit that constitutes of the 4th resistance and the 3rd electric capacity send control signal, delay circuit is made to control end output high level to silicon controlled, controlled silicon conducting, connect speaker and send chimes of doom, the present invention can be hidden in the position of secret, touch without machinery, or it is hidden in body of wall, prevent lawless person from finding, there is higher feasibility, there is the value promoted the use of.
Accompanying drawing explanation
Fig. 1 is the circuit structure schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
nullAs shown in Figure 1: the present invention includes battery E、First resistance R1 to the 3rd resistance R3、First electric capacity C1 to the 3rd electric capacity C3、Diode VD、Stabilivolt DW、Time basis set become chip IC 1、Microwave induced chip IC 2、Controllable silicon SCR and speaker Y，The positive pole of battery E simultaneously with first end of the first resistance R1、First end of the first electric capacity C1、First end of speaker Y connects，The negative pole of battery E simultaneously with the first end of controllable silicon SCR、The positive pole of stabilivolt DW、First end of the second electric capacity C2、Time basis set become the negative pole of chip IC 1、First end of the 3rd electric capacity C3 and the negative pole of microwave induced chip IC 2 connect，Second end of the first electric capacity C1 simultaneously with second end of the first resistance R1、The positive pole of diode VD and the negative pole of stabilivolt DW connect，The negative pole of diode VD simultaneously with second end of the second electric capacity C2、Time basis set become the reset terminal of chip IC 1、Time basis set become the positive pole of chip IC 1、First end of the 3rd resistance R3 and the positive pole of microwave induced chip IC 2 connect，The signal output part of microwave induced chip IC 2 simultaneously with second end of the 3rd resistance R3、Second end of the 3rd electric capacity C3 with time basis set become the input of chip IC 1 to connect，Time basis set become first end of the outfan of chip IC 1 and the second resistance R2 to connect，Second end of the second resistance R2 is connected with the control end of controllable silicon SCR，Second end of controllable silicon SCR is connected with second end of speaker Y.
When the present invention works, whether sensed by microwave induced chip IC 2 has human body to pass through, when detect have people in scope time, to by time basis set become the delay circuit that chip IC 1 and the 4th resistance R4 and the three electric capacity C3 are constituted to send control signal, delay circuit is made to export high level to the control end of controllable silicon SCR, controllable silicon SCR turns on, connect speaker and send chimes of doom, the present invention can be hidden in the position of secret, touch without machinery, or it is hidden in body of wall, it is prevented that lawless person finds, has higher feasibility.
The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described.Skilled person will appreciate that of the industry; the present invention is not restricted to the described embodiments; described in above-described embodiment and description is that principles of the invention is described; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements both fall within the claimed scope of the invention.Claimed scope is defined by appending claims and equivalent thereof.
