Abstract

The invention belongs to the technical field of industrial automatic control, relating to a method for encoding embedded human-machine interface configuration information. Generally, the embedded human-machine interface configuration software comprises a configuration development environment part and an operating environment part; the configuration information mainly includes system parameter information, menu information, correspondence address list information, character information and image lattice information; and the above information is encoded in the data areas of a configuration information profile. The configuration information encoding is of multi-layer nested indexing structure. The outer-layer index is the positioning data of all the data areas and is encoded at the start position of the configuration information profile. After that, the data of all the data areas is encoded sequentially. Inner-layer indexes are arranged in the data areas according to needs to position the internal data information in the data areas. The positioning of the data areas and the skip among the data areas can be realized according to the outer-layer index information. The invention has the beneficial effect that a method for encoding the configuration information is provided. With the method, the information is convenient to read and resolve, the storage room can be saved, the problems in storage and conversion of the embedded human-machine interface configuration information can be solved, and the interaction of the development environment and the operating environment can be realized.

Description

technical field [0001] The invention belongs to the technical field of industrial automation control and relates to a configuration information encoding method of an embedded man-machine interface. Background technique [0002] Configuration is the use of software tools to configure various resources of the computer and software, so that the computer or software can automatically perform specific tasks according to the preset settings and meet the requirements of users. The human-machine interface of the control system is the medium for transmitting and exchanging information between the user and the control equipment. The user can configure different screens according to the control needs, and use text, graphics, buttons, charts and other components on different screens. Monitor the working status of field devices. [0003] The embedded human-machine interface system is a graphic software and hardware system used to monitor, display and change a specific process or machine...
