1 //通信9个字节，前3个字节为帧头，均为0xff；第四个字节为距离，a路占高4位
2 //bc路占低4位；第五个字节位速度a路占高4位，bc路占低4位；第六个字节为A路衰减量；
3 //第7个字节为B路衰减量；第8个字节为c路衰减量；第9个字节为控制开关信号，8位分别为
4 //* * * * 相参开关，c路开关，b路开关，a路开关，其中1为开，0为关
5 //系统采用15M晶振，每100ms更新一次距离延时，每秒钟更新10次对应速度分别0，100m/s
6 //200m/s，300m/s，400m/s，500m/s，所以每100ms应该更新的距离分别为0m，10m，20m，30m
7 //40m，50m。15M的晶振一个脉冲对应的距离是10m。所以0m，10m，20m，30m
8 //40m，50m对应的脉冲改变量分别为0，1个，2个，3个，4个，5个。
