Embodiment

[0025] as attached figure 1 As shown, a time window path planning method is characterized in that it comprises the following steps:

[0026] (1) Establish a grid landmark on the path that needs to pass, using RFID electronic tags as landmarks, internal information that can be erased and rewritten, and has its own fixed and unique UUID, which is convenient for system maintenance and modification.

[0027] (2) Establish a gridded electronic map based on the gridded landmark scheduling server in step (1), avoid obstacle blocks, and find all feasible routes in space.

[0028] (3) Set the starting point and ending point in the electronic map;

[0029] (4) Use the space planning algorithm to analyze and calculate the next step from the starting point to the spatially feasible plan; according to the time window, verify the feasibility of the feasible route obtained by the space planning algorithm in time, and judge the priority according to the time set by the route Level, so as to...

Abstract

The invention provides a time window path planning method. According to the method, a mode of simulating the machine time is adopted; the requirement of a time window in a storage intelligent control system on the time precision is reduced; the requirement of the whole system on the task time precision is reduced, so that the system can deal with various emergency conditions without making mistakes.

Description

technical field [0001] The invention belongs to the technical field of intelligent storage equipment, and specifically relates to a time window path planning method based on simulated maneuvering time, which reduces the time accuracy requirements of the time window in the storage intelligent control system, and relaxes the entire system for task time accuracy requirements, so that the system can respond to various emergencies without errors. Background technique [0002] With the rapid development of the economy, the logistics industry has also been greatly developed. For the turnover of goods, it is usually necessary to build a logistics warehouse. Due to the increasing volume of goods, the workload of warehousing is also increasing and becoming more and more complex. There is an urgent need Automatic unloading and automatic loading of stored goods are realized through intelligent transformation. The intelligent warehousing system means that the logistics and transportatio...
