Abstract

The utility model discloses an electronic and mechanical combined car alarm. The car alarm is mainly composed of a controller, a wireless communication module and a gasoline pipeline controller. After a car door is opened, the controller sends a short message to a car owner through the wireless communication module so as to confirm whether a gasoline pipeline is recovered or not; if the alarm does not receive a short message containing a gasoline pipeline relieving order of the car owner, the limit to the gasoline pipeline is maintained, and therefore the alarming function is achieved. According to the car alarm, through short message verification, operation is simple, anti-cracking capacity is strong, reliability is high, the car locking function and the remote alarming function are integrated, and therefore the defects of existing mechanical and electronic car alarms are overcome.

Description

A kind of car alarm

Technical field:

The utility model belongs to electronic device field.

Background technology:

Automobile has become people's a kind of general vehicle in daily life.It is expensive very easily stolen again, so car alarm more and more promoted in the middle of life now, thereby has guaranteed people's property safety.Common mechanical type car alarm is as simple in handle lock, clutch brake lock or gear lever lock structure, is easily cracked.And get on and off at every turn and all need manual unlocking, very inconvenience.Although electronic formula car Car Burglar Alarm has added electronics built-in lock on the circuit of automobile or oil circuit, yet the mortal wound of this electronic anti-theft is its electronic cipher and remote manipulation mode.When car owner is during with remote controller close door, hide nigh car thief, can steal radiowave or the infrared ray that remote controller sends with receptor or scanning device, through decoding, anti-theft system that just can opening automobile.Therefore be just necessary to provide a kind of reliably, easily, by controlling the electric mechanical mating type car alarm of petrol line switch.

Utility model content:

The utility model discloses a kind of electric mechanical mating type car alarm.

The technical solution of the utility model is: a kind of car alarm, comprise controller, wireless communication module, petrol line controller, also comprise that the first resistance R 1, the second resistance R 2, the 3rd resistance R 3, the first capacitor C 1, the second capacitor C 2, the 3rd capacitor C 3, the first crystal resonator Y1, the first K switch EY1, second switch KEY2, first aerotron Q1 the first crystal oscillator Y1, the second capacitor C 2 and the 3rd capacitor C 3 set up into the crystal oscillating circuit of controller; The first resistance R 1, the first K switch EY1 and the first capacitor C 1 are set up into the reset circuit of controller; The 1st, 2,3 interfaces of controller are connected with the 3rd, 2,1 interface of wireless communication module; The 32nd pin of controller connects current-limiting resistance R3 and controls petrol line controller by aerotron Q1; The 21st pin KEY2 of controller is connected with current-limiting resistance R2, forms car door opening trigger circuit.

After car door opening, controller is sent short messages and is confirmed whether to recover petrol line to car owner by wireless communication module; If Car Burglar Alarm is not received car owner's releasing petrol line instruction note, keep the restriction to petrol line, realize antitheft function.The utility model is by short-message verification, and simple to operate, the anti-ability of cracking is strong, reliability is high, integrates Vehicle locking and remote anti-theft function.Thereby solved the drawback of current mechanical type, electronic formula car Car Burglar Alarm.

Accompanying drawing explanation:

For ease of explanation, the utility model is described in detail by following concrete enforcement and accompanying drawing.

The specific embodiment:

For making the purpose of this utility model, technical scheme and advantage more cheer and bright, below by the specific embodiment shown in accompanying drawing, the utility model is described.But should be appreciated that, these descriptions are exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, omitted the description to known configurations and technology, to avoid unnecessarily obscuring concept of the present utility model.

This Car Burglar Alarm comprises: controller U1, wireless communication module GSM, petrol line controller L1, the first resistance R 1, the second resistance R 2, the 3rd resistance R 3, the first capacitor C 1, the second capacitor C 2, the 3rd capacitor C 3, the first crystal resonator Y1, the first K switch EY1, second switch KEY2, the first aerotron Q1, and the first crystal oscillator Y1, the second capacitor C 2 and the 3rd capacitor C 3 are set up into the crystal oscillating circuit of controller U1; The first resistance R 1, the first K switch EY1 and the first capacitor C 1 are set up into the reset circuit of controller U1; The 1st, 2,3 interfaces of controller U1 are connected with the 3rd, 2,1 interface of wireless communication module GSM; The 32nd pin of controller U1 connects current-limiting resistance R3 and controls petrol line controller L1 by aerotron Q1; The 21st pin KEY2 of controller U1 is connected with current-limiting resistance R2, forms car door opening trigger circuit.

The utility model working process is: during use, first car alarm is placed on to concealed location in car, then petrol line controller L1 is connected on petrol line, finally by K switch EY2 with to Door Lock, be connected; When chaufeur extinguishes automotive engine, leave after automobile closed door, K switch EY2 connects, and at controller the 21st pin, produces a lasting low-potential signal; Control detects after the low-potential signal of 21 pins, controls the 33rd pin output high potential signal, connects aerotron Q1, makes petrol line controller L1 operation; The core of petrol line controller L1 is electromagnetic relay, after connecting, aerotron Q1 will form electric current in relay coil, thereby generation galvanomagnetic effect, be arranged on the pulling force that pipeline barrier flaps in petrol line will overcome return spring under the effect of electromagnetic attracting force and inhale to iron core, thereby intercept petrol line; When car door is opened again, K switch EY2 disconnects, at controller the 21st pin, produce a high potential signal, this Time Controller is sent short messages and is confirmed whether to unlock to car owner's mobile phone by wireless communication module 6SM, if not returning, car owner do not remove instruction note, the 33rd pin of controller U1 keeps high level so, and petrol line controller L1 continuous firing, realizes antitheft object.

More than show and described groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
