Problems solved by technology

[0002] At present, in terms of signal acquisition and detection software systems, a special acquisition card is generally used for data exchange with a computer. This acquisition card has the advantages of fast transmission speed and wide measurement range, but because of its high price and poor compatibility with the computer, at the same time It also faces many problems such as the difficulty of upgrading the driver program, and its scope of use is limited; Chen et al. proposed a physiological signal acquisition and processing system based on a sound card to better solve the above problems. It has low cost and superior performance. Good compatibility and other advantages, especially when the user system is upgraded, the developer hardly needs to care about the driver upgrade issues involved in the agreement with the new machine or system and control channel, but if the collected signal is more than two channels, it needs to use There are enough sound card channels or position control lines, showing the problem of low utilization rate of control lines, especially in wireless control mode, it is more likely to show the problem of low utilization efficiency of control lines
