Line RF remote is with anti theft host one-way communication；Can be locked with remote control control arrangements for automotive doors, be unlocked, while allow automobile prevent
Steal device to set up defences or withdraw a garrison；This unidirectional automobile burglar alarm price is cheap, easy to use, but has the disadvantage that security performance is relatively low and easily receive
Lawless person disturbs；Main cause is this unidirectional alarm, set up with remote control it is anti-after, the prompting that anti theft host is given is general
Only the indicator of vehicle dodges or loudspeaker pipe；In some parking sites, such as big parking lot has many to this prompting mode simultaneously
People car owner where with remote pilot car alarm or acousto-optic interference be easily disturbed and cannot certainly whether oneself
Car has been remotely-controlled antitheft.And, unidirectional automobile burglar alarm mistake of setting up defences because of firing order mistake when remote control failure or few electricity
It is common occurrence to lose.
In addition, some lawless persons implement Radio frequency interference when car owner's remote control is set up defences with powerful transmitter now, allow
Car alarm can not receive fortification command and car locking fails, and be then carried out stealing.Lawless person also have it is a kind of steal car method be：
Stealthily aside the radio frequency code of car owner's remote control is intercepted and captured with scanner when car owner is set up defences to automobile with remote control car is replicated with it
Main remote control；Then the burglary-resisting system of automobile is released with this remote control for replicating, and car is stolen.And now car owner cannot be timely
Know that car alarm is illegally withdrawn a garrison, so as to automobile cannot be prevented stolen.
The content of the invention
In order to solve the above problems, the present invention proposes the emitter of vehicle wireless alarm device, and the emitter passes through nothing
Line radio frequency sends arrangements for automotive doors to the hand-held terminal device of user and locks or unlock（Set up defences or withdraw a garrison）Deng change information, with

From the above-mentioned description of this invention, compared to the prior art, the invention has the advantages that：
The emitter of the wireless alarm of the present invention, turns to modulating signal by gathering, using automobile locking（Set up defences）Or
Person unlocks（Withdraw a garrison）Etc. the change of steering indicating light cue when state change, detect whether automobile is successfully locked or opened
Lock, and cue is sent to the hand-held terminal device of user by less radio-frequency.
Therefore, when automobile remote-control is locked（Set up defences）When, lock unsuccessful or be subject to lawless person to be disturbed with radiofrequency signal,
Cause automobile normally cannot lock, unsuccessful due to locking, turn signal state is constant, and at this moment emitter is not detected by
Upper lock signal, does not send information, and user does not receive the successful cue of locking of handheld terminal feedback, it becomes possible at once
Know that automobile is not successfully locked, effectively prevent not anti-molecule from vehicle is stolen by the method for Radio frequency interference.
When the remote control of car owner is replicated by lawless person, if lawless person is unlocked with the remote control for replicating（Withdraw a garrison）
When, the emitter of the present invention is detected unlocking signal in time, and the signal is sent to the hand of user by less radio-frequency
Terminal device is held, by the cue of hand-held terminal device, car owner knows that automobile is illegally unlocked in time, can take in time and arrange
Apply, prevent vehicle stolen.
In addition, when automobile is by illegal invasion or improper startup, in-car original alarm will send alarm signal（One
As for steering indicating light dodge simultaneously loudspeaker）, the present invention wireless alarm emitter also can by the signal be timely transmitted to use
Family hand-held terminal device, allows car owner to learn the situation of automobile in time, and takes measures.
