Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] refer to Figure 1 ~ Figure 3 , a sorting car path planning method suitable for matrix warehouses, the method includes the following steps:

[0029] Step 1. Establish a database A, the database A stores the number and location information of the trolleys that have completed the sorting of goods and have not been assigned a parcel distribution point;

[0030] Step 2, establish a database B, the real-time information of each parcel distribution point is stored in the database B, and the real-time information includes the number d(x) of sorting cars assigned to each parcel distribution point at the current moment, and the x represents is the package distribution point number;

[0031] Step 3. Traverse the status information of all sorting carts, and refresh database A and database B.

[0032] At the current moment, the information in database A is shown in Table...

Abstract

The invention provides a sorting trolley scheduling method suitable for a matrix warehouse. Two databases are established and store information of trolleys to be dispatched and information of each parcel delivery point. A batch-wise scheduling scheme is employed, after trolleys to be dispatched reach a certain amount, the overall scheduling plan planning of the batch of trolleys is carried out. Before a specific scheduling plan for the trolleys is formed, first a parcel delivery point with many trolleys is filtered, then a concept of an exclusion factor is introduced, the exclusion factor hasa positive correlation with a travel distance in a trolley return process and a number of trolleys in a parcel delivery point, and a scheduling plan with a small exclusion factor is searched preferentially in searching a scheduling plan. The invention provides the sorting trolley scheduling method suitable for the matrix warehouse, the return scheduling is effectively realized, and the sorting efficiency is improved.

Description

technical field [0001] The invention relates to the field of sorting trolley scheduling methods, in particular to a sorting trolley scheduling method suitable for matrix warehouses. Background technique [0002] In recent years, the logistics industry has developed rapidly, and the requirements for the sorting speed of express delivery are getting higher and higher. Traditional express sorting adopts manual sorting mode, but manual sorting has problems such as high cost, high error rate, and low efficiency. Therefore, the automatic express sorting method has become a research problem with strong academic significance and practical application value. [0003] In order to solve the above problems, Wang Guoping disclosed a visual recognition-based mobile robot path planning and scheduling method in the patent "A Mobile Robot Path Planning and Scheduling Method Based on Visual Recognition". Hua Songhui and others mentioned in the patent "A Robot Scheduling Method, Device and S...
