中文摘要：

为了开发电子耳蜗调试平台的体内系统,帮助电子耳蜗佩戴者个体选择最适用的言语编码策略并对其工作参数进行调试,本研究采用数据扩展编码和嵌入式脉冲控制的方式,由单片机采集言语编码序列的数据帧并解码得到刺激参数,控制输出刺激脉冲。刺激脉冲的输出通道和幅度由前一帧的刺激参数决定,脉冲宽度由当前帧的长度控制,实现了调试平台的工作参数对输出刺激脉冲的控制功能。完成了基于嵌入式脉冲控制功能的电子耳蜗调试平台体内系统的设计与调试,通过对调试平台的单电极刺激模式和非实时模式的测试,验证了所设计的调试平台体内系统具有输出连续、稳定的刺激脉冲的功能。

英文摘要：

In order to develop an in-vivo system of cochlear implant debugging platform, help individual cochlear implant user to choose the most suitable speech coding strategy and debug the working parameters, this study applies extended data coding and embedded pulse control method, makes use of microcontroller to collect the data frames of the speech coding sequence and decode to get the stimulation parameters, and controls the output stimulation pulses. The pulse output channel and amplitude of the stimulation pulses are determined by the stimulation parameters of previous frame, the pulse width is controlled by the length of current frame, thus the control function of the working parameters of the debugging platform to the output stimulus pulse is achieved. This study completes the design and debugging of the in-vivo system of cochlear implant debugging platform based on embedded pulse control mode. The debugging platform was tested in single electrode stimulation mode and non-real-time mode, which verifies that the designed in-vivo system of the debugging platform has the functions, such as continuous output and stable stimulation pulse.
