technical field [0001] The invention belongs to the technical field of space optical remote sensors, in particular to an optical-mechanical collaborative design method for space optical remote sensors. Background technique [0002] At present, the optical-mechanical collaborative design method for space optical remote sensors mainly expresses the design information by optically outputting the interdisciplinary intermediate format file model. The optical-mechanical structure is based on the intermediate file to carry out the optical-mechanical design. Output a new intermediate model file, and the structural personnel design a new optical-mechanical structure scheme based on the new model, and each iteration is carried out serially. [0003] The problems of the traditional optical-mechanical collaborative design method are as follows: [0004] (1) The intermediate format file model information for transferring interdisciplinary design information is too small, and does not in...

Problems solved by technology

[0004] (1) The intermediate format file model information for transferring interdisciplinary design information is too small, and does not include all the optical system design parameters required by optical-mechanical structure designers. The accuracy cannot be guaranteed, and there is no unified language, unified data, and A unified coordinate system is not conducive to mutual coordination and communication

[0005] (2) Optic-mechanical structure design In general, a system is completed by multi-person collaboration. The team designs based on an intermediate file model. After the design is completed, it is assembled uniformly and stacked from bottom to top to form an overall optical-mechanical structure plan. The assembly workload of the whole machine is heavy, and the interface processing is complicated

[0006] (3) With the gradual refinement of the optical system scheme, the version of the optical design parameters is changed frequently, and a new intermediate model file is output every time a scheme of the optical system is changed. Which version is used by each person in the structural designer team to carry out the design, and the technical status Difficult to control, iteration efficiency is extremely low
