Abstract

The application discloses a distance measuring system and a distance measuring method. The system includes a detection unit, a signal processing unit and a distance determination unit; Connected amplifying module and detection module; the output end of the amplifying module of the previous stage amplifying and detecting circuit is connected with the input end of the amplifying module of the latter stage amplifying and detecting circuit; the output end of the detection unit is connected with the first stage amplifying and detecting circuit The input end of the amplification module is connected; the distance determination unit is used to move forward step by step from the last stage until it is judged that the output of the current stage amplification and detection circuit is less than the current stage voltage saturation threshold, and according to the mapping between voltage and distance relationship, to determine the distance corresponding to the output of the current level of amplification and detection circuit. The scheme has the advantages of small size, high real-time performance, low energy consumption, wide dynamic range and high precision.

Description

technical field [0001] The present invention generally relates to the technical field of distance measurement, and in particular to a distance measurement system and a distance measurement method. Background technique [0002] In recent years, with the in-depth research on autonomous docking and recovery of underwater unmanned vehicles (AUV), the demand for underwater ranging has become increasingly urgent. , to avoid collisions during the recovery process and ensure the safety of the sensor; on the other hand, the AUV autonomous docking recovery path planning and power control system needs, different action distances require corresponding path planning and power control algorithms; in addition, during the recovery process, The complex and changeable sea conditions cause the positional relationship between the AUV and the recovery station to change all the time, which puts forward higher requirements for the underwater ranging function. [0003] At present, the commonly use...
