Abstract
The invention provides an automobile remote key system which comprises an automobile remote key and a car-mounted remote key servo system. The automobile remote key sends control information to the car-mounted remote key servo system, and the car-mounted remote key servo system executes control commands and simultaneously sends out confirmation response information to the automobile remote key. The design enables the automobile remote key and the car-mounted remote key servo system to possess a two-way communication link, the automobile locked condition can be directly reflected in a display alarming module of the automobile remote key, and therefore the safety problem caused by the fact that criminals adopt a car alarm jammer to interfere and shield is fundamentally eradicated.
Description
Technical field
The present invention relates to auto parts and components, particularly relate to a kind of automobile remote-control key system.
Background technology
Automobile has incorporated people's life.For the automobile that is convenient for people to use, automobile vendors have all generally used the design of remote-control key, and remote-control key can remote lock, and the automotive ignition that also is designed with that has starts function.The principle of operation of automobile remote control lock mainly is to utilize telepilot to launch one group of code signal, after receiver carried by automobile receives, will carry out driver's command adapted thereto.If have stronger microwave interference or close wave band electromagnetic wave in the surrounding enviroment, remote-controlled lock just may be malfunctioning.Some offenders adopt the car alarm interference unit, can send the high reject signal of a plurality of frequency ranges, and telepilots all in 40 meters scopes all can be interfered, shield and can't descend lock.Though the car owner presses the remote control locking key, automobile is " vacation is locked " attitude in fact, and the car owner rear robber that leaves just implements theft into the car.
For this safety problem, existing various methods based on wireless mechanism all can not overcome.These methods comprise employing coded lock, encryption lock, spread spectrum lock etc., because they all are one-way communications, send instruction by key, automobile receives signal and does not reply affirmation, cause the car owner habitually to think pressing the remote control locking key just having locked, just obviously can not tackle the problem at its root by reminding the car owner to lock car post-tensioning one door of pulling a cart.
Summary of the invention
For the problems referred to above, the present invention proposes a kind of automobile remote-control key system.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of automobile remote-control key system comprises automobile remote-control key and vehicle-mounted remote-control key servo-drive system; Described automobile remote-control key comprises control knob, first signal processing module, first signal receiver module, first signal transmitter module, display alarm module; Described vehicle-mounted remote-control key servo-drive system comprises secondary signal receiver module, secondary signal processing module, vehicle-mounted servo module, secondary signal transmitter module; In the described automobile remote-control key, described control knob connects described first signal processing module, described first signal processing module connects described first signal transmitter module, described first signal receiver module receives the affirmation signal of described automobile mounted remote-control key servo-drive system secondary signal transmitter module, described first signal receiver module is given described first signal processing module the signal that receives, described first signal processing module is analyzed the information that receives, and analysis result is by described display alarm module prompting car owner; Described automobile remote-control key display alarm module has comprised a LED lamp, a mechnical oscillator and an acoustic device; In the described vehicle-mounted remote-control key servo-drive system, described secondary signal receiver module receives the signal of described automobile remote-control key first signal transmitter module, described secondary signal receiver module is given described secondary signal processing module the signal of accepting and is processed, described secondary signal processing module is given vehicle-mounted servo module result and is carried out, simultaneously, described secondary signal processing module is given described secondary signal transmitter module after processing the confirmation coding, described secondary signal transmitter module sends to described confirmation the first signal receiver module of automobile remote-control key; Wireless channel is divided into up channel and down channel between described automobile remote-control key and the vehicle-mounted remote-control key servo-drive system, up channel refers to the communication channel between described automobile remote-control key first signal transmitter module and described vehicle-mounted remote-control key servo-drive system secondary signal receiver module, down channel refers to the communication channel between described automobile remote-control key first signal receiver module and described vehicle-mounted remote-control key servo-drive system secondary signal transmitter module, up channel and down channel adopt frequency division multiplexing or time division multiplex or code division multiplexing mode, on avoiding, channel disturbance between down channel.
Adopted technical scheme as above, the invention has the beneficial effects as follows: the present invention is because vehicle-mounted servo-drive system has increased a signal emission module, automobile remote-control key has increased a signal receiving module, so that automobile remote-control key and vehicle-mounted servo-drive system have had bidirectional communication link, the automobile locking situation directly is reflected in the display alarm module of automobile remote-control key, has fundamentally stopped to disturb, shield the safety problem that can't descend lock because the offender adopts the car alarm interference unit.
