Automatic Control System of the Inflator Based on PC and MCU

The control technology of the automatic inflator was introduced, which mainly consist of PC and MCU for automobile tyre charging. This technology takes MAX232SE as the key conversion component for the circuit interface, which help to establish a control system based on the RS232C protocol of serial port communication with the connection between the RS232C serial port of PC and the UART serial port of 89C52 MCU.This system is suitable for the small and medium department of automobile maintaining and assembling for its simple structure, low cost and friendly interface.
