Abstract: For the signal acquisition of inertial components such as accelerometers, A/D, Quantizers and I/F module are typically used for conversion. Through comparative analysis, a data conversion scheme based on I/F transformation was ultimately determined without sacrificing the original accuracy of the accelerometers. Firstly, the I/F module technology was studied, followed by software and hardware design to realize the quantization technology of the I/F module for accelerometers. Finally, the feasibility of the scheme was verified through dynamic testing of the I/F module single board and the system, meeting the requirements of single board and system indicators.
