Embodiment 1

[0049] refer to Figure 1 to Figure 6 , is the first embodiment of the present invention, this embodiment provides a kind of three-dimensional warehouse location coordinate calculation method, comprising:

[0050] S1: Transform the physical three-dimensional warehouse into a three-dimensional warehouse model, and build a cargo location coordinate value calculation network based on the neural network.

[0051] (1) Transform the solid three-dimensional warehouse into a three-dimensional warehouse model through UG software:

[0052] ①Draw the borders of all cargo locations;

[0053] The edge of the inner space of each position is the inner border of the position. Assuming that A and B are two positions, and position A is on the left side of position B, then the straight line between the right inner border of position A and the left inner border of position B is the position of position A. The right outer border and the left outer border of position B; there is an outer border b...

Embodiment 2

[0134]In order to verify and explain the technical effect adopted in this method, this embodiment chooses the coordinate calculation method based on the two-dimensional coordinate system theory and adopts this method for comparative testing, and compares the test results by means of scientific demonstration to verify the advantages of this method. real effect.

[0135] (1) The coordinate calculation model based on the two-dimensional coordinate system theory is:

[0136]

[0137] Among them, n is the number of squares from the target location to the X-axis; m is the number of squares from the target location to the Y-axis.

[0138] (2) This method divides the cargo location coordinate data in the three-dimensional warehouse model into 280 groups of training data and 32 groups of test data, tests the cargo location coordinate value calculation network in matlab, and calculates the output value; then calculates the error function value; if the value of the error function is ...

Abstract

The invention discloses a stereoscopic warehouse goods allocation coordinate calculation method, which comprises the steps of converting an entity stereoscopic warehouse into a three-dimensional stereoscopic warehouse model, and constructing a goods allocation coordinate value calculation network based on a neural network; utilizing the goods allocation coordinate data in the three-dimensional warehouse model to train a goods allocation coordinate value calculation network, and judging whether the training is completed or not through a training mechanism; if the training is completed, inputting the position data of any one goods allocation into the goods allocation coordinate value calculation network so as to obtain the coordinate value of the goods allocation. According to the method, the goods allocation coordinate value calculation network is constructed based on the neural network, and different sub neural networks are automatically activated according to the change of the input parameters, so that the output result conforming to the actual change condition is generated; meanwhile, a transformation function is designed to prevent abnormal data, and the method has higher adaptive capacity and expansibility.

Description

technical field [0001] The invention relates to the technical field of coordinate calculation of warehouse cargo locations, in particular to a calculation method for cargo location coordinates of a three-dimensional warehouse. Background technique [0002] In the three-dimensional warehouse control system, the palletizer moves to the position of the designated storage space and obtains the pallet. In order to determine the position of the cargo space, a two-dimensional coordinate system is established on the surface of the three-dimensional warehouse, so each cargo space has a definite coordinate. In order to calculate the coordinates of the specified cargo location, the mathematical model for calculating the coordinates of the cargo location is an indispensable content. [0003] When the three-dimensional warehouse increases, decreases or moves the storage space, the mathematical model based on the theory of the two-dimensional coordinate system is no longer applicable. I...
