Embodiment 1

[0045] Embodiments of the present invention provide a method for storing grain in a tall flat room, such as figure 1 As shown, the method includes:

[0046] Step S101: Obtain the data parameters of the warehouse, warehouse door, grain to be stored and storage equipment;

[0047] Here, the data parameters for obtaining the warehouse include: length of the warehouse, width of the warehouse, and height of grain stacked in the warehouse.

[0048] The data parameters for obtaining the warehouse door include: door center position, door width, door height, and sealing plate height (when grain is stacked at the warehouse door, a sealing plate needs to be installed).

[0049] The data parameters for obtaining the grain to be stored include: the type of grain, the bulk density, and the gravity angle of the grain when stacking the grain.

[0050] The data parameters of the silo loading equipment include: forearm length, maximum telescopic length, slewing height, maximum grain throwing ...

Embodiment 2

[0061] Further, in the embodiment of the present invention, as figure 2 As shown, the method for obtaining multiple grain storage paths through the ant colony algorithm based on the positions of the workable station and the export station is:

[0062] Step S411: Generate an initial ant colony with a size of m, and randomly place m ants on the m operable workstations;

[0063] Step S412: Calculate the probability of each ant moving to the exit station;

[0064] Here, the formula for calculating the probability of each ant moving to the exit station is:

[0065]

[0066] Wherein, the i represents the starting point, the j represents the end point, and the k represents a node between the starting point and the end point;

[0067] The η ij =1 / d ij Visibility is the reciprocal of the distance between two points i and j;

[0068] The τ ij (t) is the pheromone intensity from i to j at time t;

[0069] The allowed k A collection of nodes that have not been visited;

[007...

Embodiment 3

[0103] Further, as image 3 As shown, in the embodiment of the present invention, the method of selecting the optimal grain storage path according to the predetermined target is:

[0104] Step S511: Determine whether the evolution algebra is satisfied, wherein the evolution algebra refers to the number of algorithm iterations;

[0105] Step S512: If not satisfied, repeat the steps based on the positions of the workable station and the exit station, and obtain multiple grain storage paths through the ant colony algorithm until the evolution is complete, and output the optimal path.

Abstract

The embodiment of the invention discloses a grain storage method of a tall and flat warehouse. The method comprises the following steps: acquiring data parameters of a warehouse, a warehouse gate, to-be-stored grains and binning equipment; according to the data parameters, determining a position that a grain discharging opening of the binning equipment can reach in the warehouse, and determining grain bulk morphology at each point in the warehouse; determining an operable path in the warehouse, dividing the operable path into m operable stations, and setting an exit station; based on locationsof the operable stations and the exit station, obtaining multiple grain storage paths by virtue of an ant colony algorithm; and according to a predetermined target, selecting an optimal grain storagepath. Therefore, transfer probability of each operable hole location in the warehouse towards the exit station is calculated by virtue of the ant colony algorithm, and then the optimal grain storagepath is selected according to the predetermined target, so that binning quantity of a binning machine is high when grain storage is performed in the warehouse, a warehouse supplementing quantity is low, grain surface is flat, and grain surface flattening workload is less.

Description

technical field [0001] The invention relates to a method for storing grain, in particular to a method for storing grain in a tall flat warehouse. Background technique [0002] The tall flat warehouse used for grain storage is the main type of warehouse invested and built in my country in recent years. The research focus on this type of warehouse is mainly on the grain storage technology, management system, related equipment and safety operation procedures. At present, the binning machines developed by many enterprises have added driving devices, which have made good improvements in terms of conveying distance, height, binning efficiency, and safety, but lack an efficient, orderly, convenient, and safe grain binning machine. The silo process is used to guide the staff of the grain depot to load the silo in a standardized and efficient manner, so that the number of times the silo loader moves in the warehouse is small, and the silo loader and the operators maintain a certain s...
