摘　　要： 当电信号比较微弱又需要远距离传输时,线路的电阻对电压信号的衰减将被放大.汽车制动力的检测装置中的芯片AD202可将电压信号转变成电流信号进行传输,实现电气隔离.以集微控制器与数据转换器于一体的芯片ADuC845为核心,所构成的汽车制动力检测台,可对汽车制动力信号进行在线检测和补偿.同时,简述了制动力的数据采集及检测原理,给出了系统的软硬件设计. When a electricity signal is weak,and need to be delivered for a long-distance, the attenuation of voltage signal will be enlarged with the resistance of circuitry in the automobile braking force detection system. The chip of AD202 in the automobile braking force detection system can achieve electric isolation by changing a voltage signal into a current signal. This paper introduced a sort of automobile braking force detection platform core of chip ADuC845 which gather tiny controller and data diversion, carry on the online examination and compensation for the automobile braking force. At the same time, the elements of the data collect and detection principle of automobile braking force is depicted,and the software and hardware design of the system is given.
