Abstract
The utility model relates to an automobile burglar alarm comprising a host machine and a remote controller. The host machine comprises a power supply module, a host machine controller, an alarm module and a radio receiving and sending module. The remote controller comprises a remote control device, a radio receiving and sending module and a control button. The radio receiving and sending module of the host machine and the remote controller comprises a 2.4G radio communication unit. The utility model has the benefit that the whole body adopts 2.4G radio units, so bidirectional data communication is conducted between the host machine and the remote controller based on 2.4GHz, and one radio communication unit can integrate original wafer locking functions; 2.4G work has frequency modulation characteristics, fuel circuit connection and disconnection codes are updated every time, the codes automatically change in case of external interference, communication content can not be duplicated, coped and decoded by a third party in communication process, and vehicle anti-theft and tamper-proof performance is ensured.
Description
[technical field]
The utility model relates to a kind of car alarm, refers in particular to a kind of anti-snatch car alarm based on the 2.4G wireless telecommunications.
[background technology]
The early stage Car Burglar Alarm that is open to the traffic, usually the form that adopts a relay to add waved switch forms the automobile Fuel path lock and realizes, mechanical manual anti-joyride device of the more knowledge of its essence, the car owner gets on or off the bus at every turn and must waved switch can realize the unlatching of anti-theft feature.Comparing comparatively advanced later stage car alarm then is by being equipped with short range wafer lock, thereby realize antitheft open function apart from the internal induction pairing by short, but also have problem be all wafer must be locked in before each car owner drives after the induction of certain specified location can, this also can cause many inconvenience to the car owner.
Therefore, remote control class car alarm has just arisen at the historic moment, and it can be by the wireless communication mode remote control automobile unlocking operation of locking, and is very convenient, yet this also provides opportunity for the lawless person.The remote control class car alarm product institute frequency of utilization of market is 315MHZ, 316MHZ or two kinds of frequency ranges of 433MHZ, 434MHZ at present, cooresponding, it is very many that existing frequency at this frequency covers device, so-called frequency covers device as its name suggests, in case unlatching is the communication between maskable remote controller and Car Burglar Alarm, disturbs the normal use of common Car Burglar Alarm product even directly make Car Burglar Alarm lose efficacy.And this type of covers the device product frequently, and the lawless person can obtain easily by buying promptly, and therefore many lawless persons disturb the normal use of car alarm with this frequency fraud device, cause car alarm can't arrive antitheft purpose, finally allow the car owner sustain a loss.
[summary of the invention]
The purpose of this utility model is to have overcome above-mentioned defective, and the anti-snatch car alarm of the public frequency range of a kind of 2.4G of utilization as wireless telecommunications is provided.
The purpose of this utility model is achieved in that a kind of anti-snatch car alarm, it comprises main frame and remote controller composition, described main frame comprises power module, console controller, alarm module and wireless interface sending module, described remote controller comprises remote controller, wireless interface sending module and control button that its improvements are: the wireless interface sending module of described main frame and remote controller comprises the 2.4G radio communication unit;
In the said structure, described console controller is connected with relay, and central controller links to each other with automobile oil circuit motor by relay;
In the said structure, the alarm module of described main frame includes loudspeaker unit.
Than common car alarm, the beneficial effects of the utility model are that integral body has adopted the 2.4G radio-cell, thereby between main frame and remote controller, carry out two-way data communication based on 2.4GHZ, a radio communication unit can have both original wafer lock function whereby, 2.4G work has frequency modulation characteristic in addition, the password of oil circuit connecting and disconnecting upgrades at every turn, in case be subjected to the i.e. tripping automatically of external disturbance, can't duplicate, copy, decode in the communication process external world, ensure the antitheft interference protection performance of vehicle.
