As an important detecting, perception and monitoring equipment, the optoelectronic platform is always equipped with a series of optoelectronic devices such as optical imaging device, photoelectric encoder and fiber optic gyroscope. These devices all require high-precision data acquisition systems. As the basic method of sensing a variety of mass physical changes, data acquisition systems have been increasingly used in optical sensing, photoelectric platform control and many other fields. The traditional optoelectronic platform design method uses distributed device for assembly, which occupies a large volume. In this paper, we take the multi-channel acquisition system in consideration, instead of the acquisition circuit scattered in each device, during the optoelectronic platform design process, which can effectively improve the system integration. The characteristics of multi-channel and high-precision data acquisition system are studied, and a multi-channel, high-precision AD data acquisition system is designed and verified. The system provides 16 parallel channels, each channel supports 32-bit sampling accuracy, we adopts FPGA as the core processing device, with gigabit network port for data reporting, this scheme has been applied in gyro test systems and weak signal acquisition systems.
