摘　　要：设计一种基于嵌入式系统的无线汽车动态称重系统。采用ARM7处理器SEP4020、实时操作系统(RTOS)、图形用户界面(GUI)设计一台手持式终端,通过2.4GHz无线通信模块与单片机数据采集系统建立通信,单片机数据采集系统通过仪表放大器和模数转换芯片Max186采集压力传感器信号传送给手持终端。实践证明该系统是切实可行的。Wireless car dynamic weighing system based on embedded system is designed. SEP4020 ARM7 processor, re- al-time operation system and GUI technology are used and a handheld terminal is designed. Communication is established by 2.4GHz wireless communication module and the microcontroller data acquisition system. Signals are sent to hand-held termi- nals through instrumentation amplifier and analog to digital converter chip Max186 acquisition pressure sensor. Practice shows that the system is feasible.
