Description

Intellectual multipurpose automobile lock controller

Technical field

The present invention relates to multipurpose automobile lock controller, particularly incorporate automobile ignition switch, central controlled lock, engine lock in the intellectual multipurpose automobile lock controller of one.

Background technology

Current automobile on the market does not all install special engine lock additional, more ignition lock, central controlled lock is not integrated, and generally still stirs ignition lock with mechanical key, there is quilt cover and open hidden danger; Car owner will for a remote controller door opening, a slice key start a car, and boot opened by a key, extremely bothers; Especially current ignition lock is multifarious, is unfavorable for regulation and standardization.

Summary of the invention

Not installing special engine lock additional for overcoming, having the hidden danger that quilt cover is opened; Overcome the trouble of the many keys of a car; Overcome the present situation that existing ignition lock five changes eight.The invention provides a kind of intellectual multipurpose automobile lock controller, it has installed special engine lock additional, and engine lock, ignition lock, central controlled lock is integrated, only control with a remote controller, there is not quilt cover and open hidden danger, this system is convenient to standardization, normalisation.

The technical scheme that the present invention adopts for solution existing technologies problem is: engine lock, ignition lock, central controlled lock are integrated, be placed in a custom-designed short-distance wireless receive-transmit system, this system is made up of remote controller and master controller.Remote controller is by a slice microcontroller chip, a slice radio transmitting and receiving chip, 6 button switches connect to form, 6 I/O mouths of microcontroller are connected with 6 function control ends of wireless chip, another 6 I/O mouths are connected with 6 button switches, and when pressing next button, microcontroller detects that this key is pressed, just controlling wireless chip and launch corresponding center frequency signal, address signal, control command, is open the door, close the door, auxiliary power supply, startup, stop working, open boot control command respectively.Master controller is a reception template, and it is connected to form by a slice microcontroller chip, a slice radio transmitting and receiving chip, 9 executive circuit control modules.6 I/O mouths of microcontroller are connected with 6 function control ends of wireless chip, in another 9 I/O mouths, 4 I/O mouths are connected with ignition lock composite module, auxiliary power supply control module, two main power control module, starter motor energy supply control modules respectively, 4 I/O mouths are connected with central controlled lock composite module, be enabling control module respectively, close door control module, open boot control module, close boot control module, 1 I/O mouth is connected with engine lock control module.When master controller receives the signal of remote controller transmitting, first identify center frequency signal, address signal, confirm as true, then decoding function control signal, worked by the control command control corresponding units executive circuit of microcontroller according to decoding: first driver presses enabling key, open car door, enter operator's compartment, then press start key, automotive ignition starts, this moment microcontroller automatically control disconnect starter motor, automatically close car door, ensure safe driving.During parking, press flame-out key, automobile flameout, then press enabling key, car door opening, driver gets off, and presses key of closing the door, and shuts car door, leaves automobile.A remote controller is only used in whole operation, simply, safely, reliably.

The invention has the beneficial effects as follows: incorporate ignition lock, central controlled lock, engine lock function, intelligent control; Only control with a remote controller, conveniently, safely, reliably, high-tech, achieves a kind of brand-new full car without key system; Recoded by central frequency, address signal, control command three, coded combination has more than trillion groups, and mutual opening rate is less than 1/,000,000,000,000; Because master controller is loaded in headstock, where operator's compartment just can't see ignition lock at all, thinks that cover is opened and all has no way of doing it!
