Embodiment Construction

[0029] In order to make the above content, features and advantages of the present invention clearer and easier to understand, the detailed implementation steps of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0030] The invention is based on the concept of object-oriented software development, and decouples the core computing task of the controller from other tasks. The middle-level language is used to realize the interpretation and execution mechanism, and the control strategy of multi-cycle operation task operation is realized, and it supports multi-category and multi-quantity debugging instructions. The whole scheme mainly includes four parts, namely, establishing the task control block structure, establishing the first-level task control process, establishing the debugging instruction preprocessing process, and establishing the second-level task control process supporting the breakpoint debugging function.

Abstract

The invention provides a multi-task breakpoint debugging method based on an improved task scheduling mechanism, comprising the following steps: a) according to the coordination and management requirements among multi-operation tasks, a first-level task control block is defined, and one or more first-level task control blocks constitute a first-level task control queue; (b) defining a secondary task control block according to the operation requirement of a single operation task and the storage requirement of breakpoint information; C) Establishment of a first-level task management mechanism among multi-computing tasks; (d) according to the category of breakpoint debugging function, establishing corresponding instruction preprocessing mechanism for each debugging instruction, realizing the conversion of debugging instruction to structured task control description and adding the debugging instruction to the secondary task control block; E) defining a plurality of operation states of the operation tasks, and realizing the conversion between different operation states of the operation tasks. The invention ensures the execution of the operation tasks with high priority and the full utilization of the processor resources to the maximum extent, and realizes the breakpoint debugging function of the control logic.

Description

technical field [0001] The invention belongs to the field of industrial automation control, and in particular provides a multi-task breakpoint debugging method based on an improved task scheduling mechanism, which is used for the software kernel design of a distributed controller in an industrial process control system. Background technique [0002] With the continuous improvement of the industrial production process to the automation level, the DCS / PLC control system has been widely used in various fields. In the occasions where the process is complicated and the real-time and accuracy of the control are high, the distributed controller (hereinafter referred to as the controller) not only needs to have conventional control functions, but also needs to support multiple periodic computing tasks to meet the needs of different objects in the same system. Control requirements. [0003] The complexity of the application scenario directly leads to the increase of the complexity o...
