【Abstract】 To solve the examination of information in studying Jingluo, we managed to design the multi-channel signal examination system of Jingluo. The system was PC-based and instant data acquisition on multi-point.The hardware system included electrodes,analogue part, interface circuit and PC system.The software was a special program, in which the data process program, such as GRAPHTOOL could be used flexibly.In addition, the system was provided with high amplification(0 ~ 60dB) program-controlled) ,high input resistant ( l00MΩ ), high CMRR ( l00dB), low noise, reliable security simultaneously.The system turned out to be stable and equitable designed through practical use in science research.The human-computer intercourse mode was applied in the whole examination which was easily operated and could process data flexibly as well. Besides the study of electrical property of Jingluo, the system could be applied in the study of the optical, mechanics and chemistry property of Jingluo. The systme would be prosperous in the future clinical application,as well as a valuble instrument in the experiment on Jingluo.更多还原
