Excavator control program PLC code automatic generation method, test method and visual test system

Abstract

The invention discloses an excavator control program PLC code automatic generation method, a test method and a visual test system. The method comprises the steps of building a control strategy model according to user requirements; performing error checking and parameter configuration on the control strategy model; selecting a compiling environment according to the target controller; packaging the control strategy model to automatically generate a PLC code; placing the generated PLC codes in the selected compiling environment to be integrated, and generating an executable program file; and downloading the generated executable program file into a controller to be tested of the established visual test system, performing testing through a driving simulation operation table according to a test case, and checking whether the control program can operate normally and whether result output meets requirements. According to the invention, the engineering machinery excavator control program PLC code can be visually and rapidly generated, visual simulation verification is carried out, logic deviation can be found as early as possible, errors can be modified, and the working efficiency is improved.

Description

technical field [0001] The invention relates to an excavator control program PLC code automatic generation method, a test method and a visual test system, belonging to the technical field of engineering machinery. Background technique [0002] In recent years, with the emergence and development of high-tech, the technical level of construction machinery has been continuously improved. The construction machinery industry has provided a strong guarantee for the country's infrastructure construction and is one of the areas that the country encourages development. With the continuous development of the national economy and the advent of the era of the Internet, electronic information technology, and artificial intelligence, more requirements have been placed on the development of the construction machinery industry, and more and more traditional construction machinery products are shifting from manual operation to automation and intelligence. With the development in the directio...

Problems solved by technology

In the existing manual programming method, developers not only need to be proficient in the use of the software development platform, but also spend a lot of energy troubleshooting non-technical problems in the coding process. The development efficiency is low, there are many errors, and it is difficult to adapt to the follow-up system with complex functions.

Due to the poor readability of handwritten code and everyone's writing style is very different, it brings a lot of inconvenience to later maintenance and experience reference

After the program is written, the accuracy of the simulation test is low, the simulation modeling process is cumbersome, the visualization ability is poor, the human-computer interaction cannot obtain intuitive control effects, and the dynamic change process of the control cannot be seen as soon as possible before the actual vehicle test of the program. Environmental conditions, lack of sufficient verification of the road environment, relying entirely on the actual vehicle test in the later stage is time-consuming and laborious
