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

A kind of sorting trolley scheduling method suitable for matrix warehouses. Two databases are established to store the information of trolleys to be dispatched and the information of each package distribution point. A batch scheduling scheme is adopted. First, wait for the trolleys to be dispatched to reach a certain level. quantity, and then plan the overall dispatching plan for this batch of cars; before forming the specific dispatching plan for the cars, first filter out the parcel delivery points with a larger number of cars, and then introduce the concept of exclusion factor. The rejection factor is related to the return process of the cars. There is a positive correlation between the travel distance and the number of cars at the parcel distribution point. When searching for scheduling plans, priority is given to searching for scheduling plans with small rejection factors. The invention provides a sorting trolley scheduling method suitable for matrix warehouses that effectively realizes return trip scheduling and improves sorting efficiency.

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...
