The wheel flat detection equipment is a device with high requirements in security, efficiency and intelligence. Therefore we propose a new data acquisition and processing system for wheel flat detection using high-speed floating-point DSP chip TMS320c6xxx, muhi-channel parallel AD converter chip ADSxxxx , complex programmable logic device EMP7xxx and dual port RAM chip IDT7xxxx. The design and implementation methods were presented.Moreover the communication of the system with upper system and the anti-jamming design of the circuit board were explained in detail. Finally the system performance was analyzed.
