The technical scheme of the invention is further explained by combining the drawings and the embodiment.
The invention firstly discloses a Human Machine Interface (HMI) configuration system based on a binary file, which mainly comprises an upper computer configuration system (simply called an upper computer) and a lower computer running environment (simply called a lower computer). The upper computer can run in a windows system environment, and runs configuration software based on a net technology platform, wherein the configuration software is responsible for configuration of a protocol, configuration of elements, configuration page storage and final compiling to generate a configuration file (a binary file). On the other hand, a set of Graphical User Interface (GUI) platform constructed based on c + + language is operated in the lower computer environment, the platform can dynamically load a binary file generated by the upper computer, construct a configuration page configured by a User through the binary file, and finally display the configuration page on the HMI screen.
It should be understood by those skilled in the art that the host computer of the present invention can also be applied to other systems besides Windows, including but not limited to migrating corresponding software to other systems by using virtual machine technology, and is also included in the technical solution of the present invention.
Referring to fig. 1, in the upper computer system, the upper computer may select an HMI model first, and then select related information according to the HMI model to create a new project. In the process of newly building a project, the upper computer selects a preset project template in the system according to the HMI model, wherein the project template comprises initial project information and data required by the operation of the lower computer. After the project is newly built, the upper computer initializes a configuration interface, and configuration can be newly added according to needs.
As a preferred embodiment of the present invention, the project of the upper computer may include more than one configuration element.
After a new project is built, the upper computer selects a corresponding Programmable Logic Controller (PLC) device drive which needs to be connected with the HMI according to the HMI. In the upper computer system, each optional PLC device includes a corresponding driver file (suffix of.so file) and configuration information (suffix of.cfg file) corresponding to the driver file. The drive file comprises serial port and network port types according to different equipment types, and can also comprise different drive file types. The driver file determines the key to whether subsequent communication with the PLC is possible in the HMI.
And after the PLC equipment drive selection is completed, the upper computer selects the configuration elements and edits the configuration elements. Before the upper computer carries out configuration editing, the protocol document of the configuration element needs to be defined. The protocol document defines all configuration elements and data structures of the overall configuration of the configuration elements, and the upper computer and the lower computer can be normally matched according to the data structures. After the protocol document is defined, the upper computer can provide the functions of adding and editing the configuration elements in the configuration interface for the user according to needs. A set of data structure corresponding to the protocol document is arranged behind each configuration element edited by the upper computer, and the data structure of the configuration element can be converted into the data structure defined in the protocol document in the compiling operation after the configuration is completed.
And compiling the project, the PLC equipment driver and the configuration element by the upper computer after the project is built, the designated PLC equipment driver is selected and the configuration element is built. Before the compiling is started, the upper computer checks all data of the new project once, and after the data are checked to be correct, the upper computer starts to compile. The compiling operation of the upper computer is to compile the PLC device driving file into a file which can be run by the lower computer, compile all configuration element data of the new project into a data structure defined by a protocol document and generate a binary file, namely a bin file, and the bin file can be correspondingly encrypted and obfuscated.
