In order to solve the problem that the PKE (passive keyless enter) with a fixed-frequency used in middle and low grade
cars was interfered and broken easily, which
led to the damage of anti-theft system and even the loss of cars, and in order
to ensure the PKE can be used long and be expanded and upgraded in the future, a new, low power consumption and high reliability
PKE was designed with the S3C2410 microprocessor which is based on ARM9 and the
RF transceiver chip nRF905 which has the function of frequency modulation. As
frequency-hopping communication technology was used in the system, the information would not be disturbed
or blocked in the communication process, which increased the reliability of the
system. With reasonable power-management module, the system power consumption
was greatly reduced. Test shows that the new PKE can well meet the practical
application.
