Transmitter, RF Keyless Entry System
1.
Constitution of the Radio Frequency Keyless Entry
System for vehicle
The radio frequency keyless entry is a system that it controls locking and unlocking the door and alarm
the horn by wireless remote controller. This system consists of threecomponents. The TRANSMITTER is a
device that transmits the signal when the button is pressed.
The transmission signal consists of several
synchronous codes, unique identification code, securitycodeandfunctioncode.The RECEIVER is fixed inside
the vehicle. It works intermittently to prevent the battery exhaustion. When the receiver detects the
synchronouscode,itrunscontinuouslyto receive the signals completely. Afterreceiving the signal, the receiver
decides which operation will be performed. The user can select the following operations by pressing the
button of the remote transmitter.
OPERATION

LOCK
When you push the LOCK button, all the doors will lock.
You cannot lock any of the doors with the remote transmitter if any door is open or the key is the
ignition switch.
UNLOCK
When you push the UNLOCK button, all the doors will unlock.
You cannot unlock any of the doors with the remote transmitter if any door is open or the key is in the
ignition switch.

4.Features
4.1 Transmission frame
The transmission begins immediately in case of LOCK and UNLOCK and PANIC button is pressed.
The transmission frame consists of the synchronous frame and the data frame. The synchronous frame
has 30 synchronous codes that it will be used for the receiver to wake up. The data frame consists of
24bit length identificationcode,16bit security code and function code. 16million different identification codes
are available.
The security code is always changed in case of any of the buttons is pressed. The transmission time is
typically 300 milliseconds.
4.2
Battery saving
To prevent the battery exhaustion , the micro-computer of the transmitter is usually inactive. When the button
will be pressed, the micro-computer wakes up immediately and judges which button is pressing. Then the
micro-computerconstructs the transmission frame and radiates it from the antenna .Aftertransmitting , the
micro-computer switches stand-by mode by itself.
