Abstract

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.
