This thesis focuses on the optimum design of excitation module, filtering module, detector’s interference suppression and serial synchronization matching communication of terminal in multi-channel impedance detector of visualization system. And the optimized system has been tested, which confirms that the optimized system has improved the measurement accuracy performance. The thesis also briefly introduces whole meridian visualization system.%该文对可视化系统中多通道阻抗测试仪的激励模块、测试仪干扰抑制以及上下位机串口同步匹配通信模块进行了优化设计，并对优化后的系统进行测试，通过实验证实了优化后的系统在测量精度等性能指标上有较大的提高。该文还对整个经络可视化系统进行了简要介绍。
