Abstract
The utility model discloses a wireless article antitheft 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 vibrating motor are installed in the housing. A 9V Ni-MH rechargeable battery is installed in the battery case to form an external DC power supply. 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 vibrating motor 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 vibrating motor are all connected with ground. The wireless article antitheft device is simple in circuit structure and small in size. An elastic rope may pass through the hanging rope holes to tie the wireless article antitheft device to a luggage case or portable bag. Or the wireless article antitheft 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 wireless articles anti-theft 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 the plain conductor that is connected an outer painting insulation course between control circuit board and antitheft article, and only have thief to cut off plain conductor and just send alarm signal, but 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 cannot send alerting signal, cannot play actual anti-theft function.
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 wireless articles anti-theft device of 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, vibration motor are housed in shell; 9V nickel-hydrogen chargeable cell is housed in battery case and forms 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 vibration motor 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 vibration motor 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 vibration motor are sounded and lasting vibration 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, vibration motor 7 are housed in shell; 9V nickel-hydrogen chargeable cell is housed in battery case and forms 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, grounding pin, hummer 5 and the equal ground connection of vibration motor 7 of miniature Arduino control panel 3, ultrasonic sensor 4 ultrasonic sensors.
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 safe 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 that returns, 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 and the vibration motor 7 that are connected in parallel with the D5 pin of miniature Arduino control panel 3 are sounded and lasting vibration signal, play 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.
