Abstract

The invention relates to the field of control system software design, and provides a control system software design method in order to improve the development efficiency, reduce the maintenance cost and facilitate system upgrading, which comprises the following steps of: 1, defining a control parameter to be changed as a variable; 2, dividing a compiled target file into a logic area and a data area; 3, writing a control parameter value into a memory; 4, reading the control parameter value; and 5, forming a control parameter information table. The invention discloses a control system software change method. The control system software change method comprises the steps of 1, loading a target file; 2, loading a control parameter information table; 3, visually displaying related values of thecontrol parameters; 4, changing the value of each control parameter in a visual interface, and changing the value of the control parameter related to the value; and 5, forming a new .HEX or .BIN file.By using the technical scheme provided by the invention, the development efficiency is improved, the maintenance cost is reduced, and system upgrading is facilitated.

Description

technical field [0001] The invention relates to the field of control system software design, in particular to a control system software design method and modification method. Background technique [0002] The main function of air-conditioning product software is to realize the control of compressors, fans and other actuators according to certain control logic according to various control parameters to meet the user's setting requirements. The control parameters include compressor speed, fan speed, frequency jump point, exhaust temperature protection, protection current, etc. The control logic of products of the same series and the same function is the same, and the difference in control software is mainly in the control parameters. For example, the difference between 1P on-hook and 3P cabinet is the difference in parameters such as compressor speed, fan speed, and frequency jump point protection parameters, and the control logic is the same. The control parameters of the co...
