Abstract
The utility model discloses an acousto-optic antitheft alarm device comprising an ABS housing. Hanging rope holes are disposed on the two sides of the housing. A battery case, a micro Arduino control board, an ultrasonic sensor, a buzzer, and a light emitting diode are installed in the housing. A 9V external DC power supply formed by six AAA common batteries is installed in the battery case. A power leading-out wire of the battery case is connected with the VIN pin of the Arduino control board. The D5 pin of the Arduino control board is connected with the buzzer and the light emitting diode in parallel. The D2 pin of the Arduino control board is connected with the SIG-marked pin of the ultrasonic sensor. The 5V pin of the Arduino control board is connected with the power pin of the ultrasonic sensor. The Arduino control board, the ground pin of the ultrasonic sensor, the buzzer, and the light emitting diode are all connected with ground. The acousto-optic antitheft alarm device is simple in circuit structure and small in size. An elastic rope may pass through the hanging rope holes to tie the acousto-optic antitheft alarm device to a luggage case or portable bag. Or the acousto-optic antitheft alarm device can be placed in a clothes pocket and is easy and flexible to use.
Description
Technical field
The utility model relates to a kind of alarm, especially relates to a kind of acousto-optic anti-theft alarm device.
Background technology
When people go out, do shopping or travel, the little article (as mobile phone, wallet) that often occur oneself to wrap in interior or pocket go adrift, and to people, cause loss economically, and people's normal life is disturbed.Existing alarm is mainly used in as automobile, motorcycle etc., but it is less that the little article of individual are carried out to real effectively antitheft alarm.Article anti-theft device described in patent 200520078901.9 must utilize and between control circuit board and antitheft article, be connected an outer plain conductor that is coated with insulation course, and only have thief to cut off plain conductor and just send alarm signal, yet this device cannot actually be applied, because antitheft article are not damaging the plain conductor that is difficult for connecting alarm control circuit board in article surface situation as mobile phone or wallet, even and the upper plain conductor of connection, if thief does not cut short plain conductor, still alerting signal cannot be sent, actual anti-theft function cannot be played.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of simple in structure, and volume is little and be convenient to a kind of acousto-optic anti-theft alarm device of practical application.
The utility model adopts following technical scheme: comprise ABS shell, it is characterized in that: shell both sides arrange lanyard hole, and battery case, miniature Arduino control panel, ultrasonic sensor, hummer, light emitting diode are housed in shell; No. seven common batteries of 6 joint are housed in battery case and form 9V external direct current power supply, battery case power supply is derived line and is connected with the VIN pin of miniature Arduino control panel, and D5 pin and hummer, the light emitting diode of miniature Arduino control panel are connected in parallel; The D2 pin of miniature Arduino control panel is connected with the pin of the SIG mark of ultrasonic sensor; The 5V pin of miniature Arduino control panel is connected with the power pins of ultrasonic sensor, the equal ground connection of grounding pin, hummer and light emitting diode of miniature Arduino control panel, ultrasonic sensor.
Good effect of the present utility model is as follows: the utility model circuit structure is simplified, and volume is little and independently-powered.By lanyard hole cross-under one stretch cord, it can be luggage case, portable package is wrapped, also can be placed in pocket, apply convenient, flexible, in the time that ultrasonic sensor detects people or thing and is less than near distance the safe distance setting in advance, hummer and light emitting diode send sound and light alarm signal simultaneously, play the caution anti-theft effect of pointing out, and ultrasonic sensor is not affected by light, applicable equally during detecting obstacles thing in the dark.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is circuit connection diagram of the present utility model.
Embodiment
As shown in accompanying drawing 1 and Fig. 2, the utility model comprises ABS shell 1, and shell 1 both sides arrange lanyard hole 2, and battery case, miniature Arduino control panel 3, ultrasonic sensor 4, hummer 5, light emitting diode 7 are housed in shell; No. seven common batteries of 6 joint are housed in battery case and form 9V external direct current power supply 6, battery case power supply is derived line and is connected with the VIN pin of miniature Arduino control panel 3, and the D5 pin of miniature Arduino control panel 3 is connected with hummer 5; The D2 pin of miniature Arduino control panel 3 is connected with the pin of the SIG mark of ultrasonic sensor 4; The 5V pin of miniature Arduino control panel 3 is connected with the power pins of ultrasonic sensor 4, the grounding pin of miniature Arduino control panel 3, ultrasonic sensor 4, hummer 5 and the equal ground connection of light emitting diode 7.
Preferably, miniature Arduino control panel 3 adopts Arduino Nano 3.0 ATmega328 development boards, and ultrasonic sensor 4 can adopt HY-SRF06 ultrasonic sensor, detection range: 2cm-450cm, precision can reach 1mm.Arduino Nano 3.0 ATmega328 development boards adopt Atmel Atmega328P-AU single-chip microcomputer, base and the extra small Simple i/o platform of opening source code, highly integrated, be beneficial to and dwindle machine volume, USB interface by miniature Arduino control panel 3 is connected communication with PC computer, can on PC computer, adjust the interior default critical distance value of miniature Arduino control panel 3.
The D2 pin of miniature Arduino control panel 3 is connected with the pin of the SIG mark of ultrasonic sensor 4, the 5V pin of miniature Arduino control panel 3 is connected with the power pins of ultrasonic sensor 4, make miniature Arduino control panel 3 can receive the signal that ultrasonic sensor 4 transmits, and realize and control ultrasonic sensor 4.Miniature Arduino control panel 3 is controlled ultrasonic sensor 4 and is sent a pulse signal, and receive the pulse signal return, utilize the principle that the signal backspace time is directly proportional to the distance of ultrasonic sensor 4 to object, miniature Arduino control panel 3 calculate ultrasonic sensor 4 in its measurement range hithermost object apart from the distance of sensor.In the time that the people who detects when ultrasonic sensor or article being less than near distance the safe distance setting in advance, the D5 pin output high level of miniature Arduino control panel 3, the hummer 5 being connected in parallel with the D5 pin of miniature Arduino control panel 3 sends sound and light alarm signal with light emitting diode 7, plays the effect of prompting caution anti-theft.
The utility model circuit structure is simplified, and volume is little and independently-powered.By lanyard hole cross-under one stretch cord, can be luggage case, portable package be wrapped, and also can be placed in pocket, is easy to apply.
