A special data acquisition equipment was designed to meet requirements of miniaturized,generalized and multi-functional testing. DM642 is used as master control CPU. Several data acquisition functions,such as 100 M high-speed AD,dual-channel insulative AD,6-channel low-speed AD and DMM are all integrated in the equipment. The network control is achieved by DSP/BIOS operating system with DM642 embedded and NDK. The DSP/BIOS operating system is utilized to provide multiple threads mechanism for the implementation of mission management to data acquisition channel. The actual application of the equipment shows that the design of the equipment is reasonable,it works stable and can meet the practical requirements.
