| Abstract: | By analyzing the generation mechanism of mileage signal,this paper presented a mileage optimization algo rithm based on FPGA architecture,presented the hardware architecture diagram of the algorithm,and designed the corre sponding hardware circuit and simulation experiment.The results show that this algorithm can select and collect the pulse signals of three speedwheels,and give the correct pulse control signals when the speedwheels are in overspeed or stop state. |
