Transmission light path route planning method, device, electronic equipment and storage medium Technical Field The present invention relates to the field of route planning technologies, and in particular, to a transmission optical path route planning method, a device, an electronic apparatus, and a storage medium. Background With the rapid development of the emerging technologies such as 5G, the Internet of things, cloud computing and the like, the network bandwidth requirement is continuously increased, and the service types are also diversified day by day. The method not only puts higher requirements on the transmission speed and the reliability of the network, but also makes the route planning in the optical network a key link for ensuring the optimal configuration of network resources and the high-efficiency and stable operation of the network. In the prior art, the task of routing transmission paths is typically performed manually by a network operation and maintenance engineer. Specifically, when receiving a new service opening requirement, an operation and maintenance engineer needs to first query and comb massive network resource data such as a topology structure, distribution and occupation conditions of optical cable cores, fiber jump information of an optical distribution frame and the like in the current optical network. Then, based on personal expertise and operation and maintenance experience, engineers manually design a transmission optical path meeting basic connectivity requirements in the mind or by means of some simple drawing tools, comprehensively considering various factors such as the starting point and the end point of service, path length, available resources and the like. However, the above-described manner of performing the light path planning depending on the manual experience has the following disadvantages. Firstly, the planning mode is seriously dependent on manual operation, the whole process involves a large number of data inquiry, comparison and decision links, the processing efficiency is low, and the requirements of quick opening and dynamic adjustment of the current service are difficult to meet. Secondly, in the face of multiple mutually restricted planning targets such as path length, resource utilization rate, fiber hopping times and the like, comprehensive and quantitative comprehensive evaluation is often difficult to perform by manual decision, the planning result is usually a compromise choice under subjective judgment of engineers, rather than an optimal solution balanced among the multiple targets, which easily causes excessive centralized use of partial optical cable resources in the network and long-term idle of other resources, so that the utilization rate of the whole network resources is not ideal. Disclosure of Invention The invention provides a transmission light path route planning method, a device, electronic equipment and a storage medium, which are used for solving the defects that light path planning in the prior art depends on manual operation, has low efficiency and is difficult to meet the requirement of quick service, and a plurality of constraint targets are processed by lacking quantitative comprehensive evaluation, so that the planning result is subjective, the resources are not utilized uniformly, and a global optimal solution cannot be obtained.
