A Simulation Calculation Method for the Dimension Parameters of Bulk Material in Stockyard

Abstract

The invention discloses a stockyard bulk cargo boundary dimension parameter analog calculation method. The stockyard bulk cargo boundary dimension parameter analog calculation method comprises the following steps of establishing a mathematical model; in the model, enabling a stacker-reclaimer to discharge to form into material piles W1, W2, W3 to Wn at operation positions and enabling the integral shape of a final article material pile to be formed by a series of cones and the cones to be mutually overlapped; obtaining the discharging amount C1, C2, C3, to Cn of the stacker-reclaimer at every operation position through a belt weigher; establishing an algorithm, calculating the appearance size of the material piles W1, W2, W3 to Wn according to the stacker-reclaimer displacement B1, B2, B3 to Bn in the article materials and the discharging amount C1, C2, C3, to Cn of the stacker-reclaimer at every operation position and accordingly obtaining the appearance size of the material piles in some article material. The stockyard bulk cargo boundary dimension parameter analog calculation method provides a reliable, rapid and economic mean for larger-sized bulk cargo stockyard managers and the larger-sized bulk cargo stockyard managers can timely grasp spatial states of the stockyard.

Description

technical field [0001] The invention belongs to the field of automatic control and management of a large-scale bulk cargo stockyard, and in particular relates to a method for simulating and calculating the external dimension parameters of a stockyard bulk material. Background technique [0002] At present, in the field of large-scale bulk cargo yard management, it is an important link in the management of large-scale bulk cargo yards to grasp the spatial status of the warehouse in a timely manner. It is related to the site allocation of incoming materials and directly affects the efficiency and benefits of stockyard operations. Since the raw materials of the large-scale bulk storage yard are constantly coming in and out, how to grasp the spatial status of the large-scale bulk storage yard in time is also a difficult point in the management of the large-scale bulk storage yard. At this stage, the inventory of materials and the space occupancy of the stockyard are mainly estim...

Problems solved by technology

[0004] The present invention aims at the problem that in the existing automatic control and management technology of large-scale bulk cargo yards, the space utilization of the yard cannot be grasped accurately and timely, and the distribution of incoming materials cannot be optimized, and a bulk material shape parameter of the yard is provided. Compared with the method of visual observation to observe the spatial state of the stockyard, the simulation calculation method is more accurate and reliable. At the same time, compared with the three-dimensional scanning method for measuring the shape parameters of each stockpile in the stockyard, the method of the present invention is lower in cost and easier to use. Fast and real-time
