Abstract: A photoacoustic spectrum phase locking method, apparatus, and system are provided. The photoacoustic spectrum phase locking method includes: acquiring a mapping relationship between an output amplitude and an output phase of a photoacoustic spectrum system; determining a reference phase of the photoacoustic spectrum system according to the mapping relationship; and adjusting scanning parameters of a laser in the photoacoustic spectrum system according to the reference phase, so that an output phase in a current preset cycle of the photoacoustic spectrum system is equal to the reference phase.

Abstract: The present invention is to provide a solution of high density storage and goods-to-man picking by proposing a three dimensional warehouse system for accurate inbound and outbound operation and management and improved space utilization rate of the warehouse. The technical solution includes a rack, containers, carrier vehicles, and track-switching devices. The rack includes a track structure and defines at least one load-bearing platform. The track structure includes running tracks, and the at least one load-bearing platform located below the running track. Each container stores goods, and part of the containers are stacked and placed on the at least one load-bearing platform. The carrier vehicle moves back and forth on the running tracks to perform storage and retrieval operations in the container storage system. The track-switching device is configured to switch the carrier vehicle from a current running track where the carrier vehicle is located to a target running track.
