Design of multifunctional data recording system based on CAN bus communication

Taking data collection and recording in special environments as the research object, for the characteristics of confined and narrow spaces, high anti-interference requirements, accurate and reliable data recording, a multi-functional data recording system which is applicable to the underwater unmanned vehicle (UUV) is designed. In this paper, the design of the data recording module, sensor module 1, sensor module 2, and video acquisition module based on CAN bus communication is introduced in detail. In addition, two types of underwater unmanned vehicles with multi-functional data recording system were used to take sailing verification, and the results show that the system has achieved the expected purpose.
