Embodiment Construction

[0024] Combine below figure 1 , figure 2 The specific implementation of the sequence control method based on the task queue is illustrated by the flowchart of the sequence control method based on the task queue of the converter batching system.

[0025] Such as figure 1 Shown: the sequential control method in the present specific embodiment comprises the steps:

[0026] Step 100: Invoking the module of "maximum set of materials with the same scale" module, scanning the formula table after the formula is confirmed and approved, and generating a queue of "maximum sets of materials with the same scale" marked with several My. The value of element My in the "maximum set of materials with the same scale" queue records the discharge sequence of these "maximum sets of materials with the same scale", and the subscript y=1 to m is the "maximum set of materials with the same scale" in the queue Number, the My value of the adjacent element number, may be equal or increase relative to...

Abstract

The control process based on task queue includes the following steps: the step of creating 'maximum same-weighing unit material variety set' queue including confirming recipe and scanning recipe list to create several My labeled 'maximum same-weighing unit material variety set'; the step of writing in task queue to establish for each material compounding weighing unit one circulating task queue and several interruption task queues controlled with separate task writing in pointer and task executing pointer; the step of interruption processing to write the task to the interruption task queue and create interruption request label; and the step of processing task to write different kinds of task to the queue. The present invention simplifies complicated technological process via writing task queue and control system configuration.

Description

technical field [0001] The invention relates to a task queue-based control method for an automatic control system of an industrial and mining enterprise, in particular to a task queue-based control method for multiple multi-material batching scale systems. Background technique [0002] The automatic control system of industrial and mining enterprises needs to implement complex and changeable control commands in order to cope with complex process requirements. [0003] For example, multiple batching scales are often used for the input system of auxiliary raw materials and alloy materials in steelmaking plants. Each batching scale corresponds to multiple upper silos, so that multiple materials can be prepared together. This type of system is a system of multiple multi-material batching scales. The batching system of ordinary industrial and mining enterprises has simple process requirements. Usually, when setting the feeding formula, there are only requirements for the type ...
