The invention discloses a full-automatic material carrying system for a square freeze dryer. The system comprises the square freeze dryer, a material transfer trolley, an automatic guide transport vehicle, a butt joint auxiliary device, a vehicle-mounted locking mechanism and a fleet management system. The automatic guided vehicle is a low-temperature-resistant condensation-preventing AGV, a hybrid navigation mode with two-dimensional code navigation as a main part and laser radar as an auxiliary part is adopted, the working part of the automatic guided vehicle is provided with an active temperature control cabin, self-adaptive switching between a low-temperature mode and a normal-temperature mode can be achieved according to the environment temperature, and the problem that the automatic guided vehicle carries out transportation across an ultra-low-temperature area is solved. Seamless butt joint between the butt joint auxiliary device and a guide rail arranged in the drying box is achieved. And the AGV is changed from carrying to pushing in front of the drying box, so that the interference of narrow gaps between the heating plates in the freeze-drying box on the movement and unloading of the AGV is well solved. Through cooperative control of the motorcade management system, the whole-process unmanned carrying of the material transfer trolley in the loading area, the pre-freezing warehouse, the drying box and the packaging area is achieved.

The invention provides a fusion map generation method and an intelligent car control method. The fused map generation method comprises the following steps: mapping original map data of a plurality of navigation modes into a plurality of logic sub-layers of a fused map, and generating standard map data in different logic sub-layers; when the navigation mode is the laser radar navigation mode, generating standard map data in the background sub-layer; and when the navigation mode is the linear navigation mode or the matrix two-dimensional code navigation mode, generating standard map data in the path sub-layer. Original map data from different sources are fused into unified standard map data in a plurality of logic sub-layers of a fused map through a mapping relation, isomerism is digested through the fused map, and the problem of complexity of an original system is solved. According to the method, the existing facts are respected, the data consistency and uniformity are realized, the universality and usability of the fused map are enhanced, and the adaptability of the fused map is improved.
