Design of the wireless code update system based on the tire pressure monitoring transmitter

The design scheme of a wireless code update system based on the tire pressure transmitter is presented by the introduction of tire pressure monitoring transmitter working environment and structure. The scheme consists of microprocessor, low frequency LF transmitter and high frequency RF receiver. The binary data of low frequency LF transmitter is responsible for sending flash, high frequency RF receiver is responsible for recording monitoring results of the transmitter. The key technologies in the hardware and software design of the system are discussed in detail.
