Abstract

The utility model relates to an antitheft alarm for car, utilizing the bluetooth technology, which consists of a core processor, a blue tooth communication module group, an antitheft speaker control loop, a direction light control loop, a door lock starter control loop and a power steady pressure circuit. Using by cooperating with the internally built bluetooth communication module group of the mobile phone, the utility model not only releases the burden of the user carrying the remote control, but adopts the frequency hopping mode through the wireless channel of the bluetooth, being not apt to be interrupted; and moreover, by means of the 128 bits protection coding, the utility model increases the safety, comparing to the single transmission method of the traditional remote control. Through the double way transmission, the utility model affirms the user bluetooth mobile phone and the antitheft alarm, and after affirming the user identity, instantly opens the automatic door lock, promising the user easily and conveniently drive the auto.

Description

Use the car alarm of blue bud technology

Technical field

The utility model is the car alarm that uses blue bud technology about a kind of, be meant especially and a kind ofly frequency existed by blue bud technology: between 2400～2483.5MHZ with 1600 times/second mode frequency hopping, and at every turn the mode with the frequency interval of 1MHZ changes, add the two-way safety coding high with 128bits, and can allow the user set up remote operated distance on their own, make convenient and take into account wireless untouchable key safely to be achieved.

Background technology

Progress along with science and technology, the more and more miniaturization of the volume of remote controller and weight, but because the relation that can't effectively integrate, therefore people's key and remote controller quantity on one's body will get more and more now, so the user is produced the inconvenience of carrying, and automobile on the living conditions institute's role heal come important more, therefore regular meeting sees that the user is in inconvenience, still need to come the switch of control vehicle door lock and Car Burglar Alarm with remote controller, as: when going out shopping, two hands have been carried big and small shopping bag, also need seek remote controller and push button and remove antitheft and the unlatching door lock; Or because of repair, carwash gives the third party with remote controller, the problem that then is copied; The generation of the problems referred to above has caused cooresponding burden really for busy modern.

At present, when realizing anti-theft warning, Door Lock unlatching or locking function with Car Burglar Alarm, the mode of the low frequency that is not to use lower cost but is subject to disturb, it is exactly the higher high-frequency mode of use cost, but both have a unique common ground is exactly function singleness, and the function that can only reach anti-theft warning, door lock for vehicle unlatching or lock can't expand other functions, use the low frequency mode if consider cost, then can't accomplish bidirectional transmission and tight safety.

Now the mobile phone that belongs to wireless product gradually become the indispensable daily necessities of modern, blue bud wireless communication technique is also ripe gradually simultaneously, how it being combined applies on the car alarm, is being subjected to people's attention to improve user's convenience in life.

This shows that above-mentioned known devices has many shortcomings and deficiency, real non-one kindhearted design, and demand urgently being improved.

Every shortcoming that the utility model applicant derives in view of above-mentioned known car alarm is urgently to think to be improved innovation, and after concentrating on studies through taking great pains to attain one's goal for many years, successfully the car alarm that this part uses blue bud technology is finished in research and development finally.

The utility model content

The purpose of this utility model is to provide a kind of car alarm that uses blue bud technology, it utilizes the function of blue bud bidirectional transmission, replace the shortcoming that the original remote controller of Car Burglar Alarm can only the unidirectional transmission data, and allow the user not need to go again ammonium key by on the remote controller, just can reach the purpose of antitheft setting and antitheft releasing, and, safety and reliability have more been increased because coded system is tighter.

Of the present utility model time a purpose is to provide a kind of car alarm that uses blue bud technology, it can increase user's convenience, also can allow the hommization more of automobile burglar function, hereafter the user does not need to carry a plurality of remote controllers again, in the time of just reaching flame-out the driving, automatic antitheft is set, and automatic antitheft is removed when preparing to drive near vehicle, it is antitheft that the user does not need to worry whether forgotten setting, realizes wireless key.

Another purpose of the present utility model is to provide a kind of car alarm that uses blue bud technology, it allows the user to set up the distance of control Car Burglar Alarm on their own, wish to open the door as soon as possible can with distance setting far away promptly move, and wish to worry a bit safely too early to open the door and can be invaded by the ruffian, then more nearer apart from setting.

Another purpose of the present utility model is to provide a kind of car alarm that uses blue bud technology, adopt the utility model user as long as when installing for the first time, after allowing anti theft host and mobile phone authenticate mutually, just do not need the problem of worrying that again remote control problem and remote controller can be copied and duplicate later on.

The utility model purpose again is to provide a kind of car alarm that uses blue bud technology, but sacrificial vessel has the mobile phone of blue bud communication module to carry out the setting or the releasing of Car Burglar Alarm with induction or manual key mode.

To achieve these goals, the utility model uses the technical scheme of the car alarm of blue bud technology to be: be made up of system core treater, blue bud communication module group, anti-theft loudspeaker control loop, indicator control loop, door lock actuator control loop and power supply stabilization circuit, when the utility model Car Burglar Alarm, the blue bud mobile phone that detects the user enters in the communication context of blue bud, confirm identity immediately mutually, begin swap date after determining, Car Burglar Alarm automatically terminates antitheft immediately when signal strength arrives the intensity of user's setting; Otherwise after vehicle was flame-out, the user left vehicle, and signal strength when being lower than the intensity that the user sets Car Burglar Alarm automatic setting is antitheft immediately.

The car alarm of the blue bud technology of utilization provided by the utility model when comparing mutually with other prior aries, has more following advantage:

One, is provided with blue bud communication module group in the utility model anti theft host, as long as the user is when installing for the first time, allow anti theft host and blue bud mobile phone mutually after the authentication, later user does not just need the problem of worrying that again remote control problem and remote controller can be copied and duplicate.

Two, after the utility model anti theft host is set and is finished, just can offer convenience for the user immediately, hereafter the user does not need to carry a plurality of remote controllers, just can reach flame-out when leaving vehicle automatic setting antitheft, automatically terminate antitheft when preparing to drive near vehicle.

Three, the blue bud communication module group in the utility model anti theft host has complicated signal distance calculation procedure, and that the user can set is antitheft, set and the theft-proof distance of releasing.

Four, the utility model is considered also that mobile phone there is not electricity or also can be by manually being reached the purpose of antitheft setting and antitheft releasing when not taking with oneself, and utilize and manually also do not lose safety, because must be, therefore must there be key could allow the setting of anti theft host antitheft and remove antitheft action through Door Lock and the steering lock twice outpost of the tax office.

Five, the utility model uses the car alarm of blue bud technology, but sacrificial vessel has the mobile phone of blue bud communication module to carry out the setting or the releasing of Car Burglar Alarm with induction or manual key mode.
