Problems solved by technology
The raw materials in the trough are transported separately by trolley. At present, the raw material trough always stops shaking due to insufficient raw materials, which makes the feeding efficiency very low.
In order to make the feeder work at the best efficiency and ensure that the most raw materials can be mixed during a working team, the current theoretical research on various optimal configurations and optimal operation methods is mostly in the stage of mathematical models and system simulations. practical application

Embodiment Construction
[0022] The present invention will be further described below in conjunction with specific examples and accompanying drawings.
[0023] The present invention provides a timing optimization method for the feeding trough of the raw material field based on the prediction principle, such as figure 1 with figure 2 As shown, the raw material 4 is fed to the trough 1 through the conveyor belt 2, and the conveyor belt 2 is transported to the feeding port of the trough by the trolley 3. The method is as follows: Figure 4 shown, including the following steps:
[0024] S1. Take the leftmost trough as the first trough, the coordinate of the first trough is 0, the distance between adjacent troughs is L, and the coordinate x of the i-th trough from the left i =(i-1)×L; Collect the weight of the trough by setting a weight sensor at the bottom of the trough, periodically collect the weight of the trough, and select several troughs lower than the lower weight limit LOW as the feeding trough...

The invention provides a method for optimizing the timing of feed troughs in the raw material yard based on the prediction principle. The weight of the troughs is collected periodically, and several troughs lower than the lower weight limit LOW are selected as the feeding troughs; the number of idle trolleys is calculated, And record the trough corresponding to the idle trolley; according to the number and position of the feeding trough and idle trolleys, obtain several feeding strategies according to the arrangement and combination, and calculate the movement time and moving mileage of each idle trolley under each strategy. , obtain the maximum value of the moving time of each idle car under each strategy and the sum of the moving mileage of the idle car; select the loading strategy corresponding to the objective function for loading; determine whether the working time of the car exceeds the maximum value; if so, then Output the loading sequence. The invention is based on the prediction principle, allowing the entire feeding trough to obtain the feeding sequence with the maximum unloading time, completing the feeding system to maximize the feeding amount per unit time, improving the productivity of the raw material plant, and saving productivity and energy.
Description
technical field [0001] The invention belongs to the design field of a feeding trough system in a raw material factory, and in particular relates to a timing optimization method for a feeding trough in a raw material field based on a prediction principle. Background technique [0002] The feeding system of the wharf raw material factory is a system that uses the trough to uniformly mix various raw materials according to a certain feeding rate. When the raw materials are mixed, each trough does not feed continuously. It is necessary to ensure that the raw materials in each chute can neither overflow nor be less than half the weight of the raw material chute. The raw materials in the trough are transported separately by trolleys. At present, the raw material trough always stops shaking due to insufficient raw materials, which makes the feeding efficiency very low. In order to make the feeder work at the best efficiency and ensure that the most raw materials can be mixed during...
