Data acquisition system design of bridge rubber bearing test machine on ARM9

Considering the real-time and stability for data acquisition in bridge rubber bearing test machine, the hardware platform used em9260 core board and Constructed the Embedded data acquisition system based on ARM9 With dialgauge, load sensors, data acquisition cards and other hardware. The system of the structure is discussed in the Article, which presents the External hardware circuit and the flow chart of the embedded system control software and PC control software. After a series of actual tests, it is proved that the system is reasonable, and the system works stably. It achieves the design requirements.
