Problems solved by technology

[0005] The current simulation system cannot take advantage of the characteristics of Internet interconnection and timely communication with third parties. It can only install special simulation software on a single computer for simulation, and cannot share the simulated system, program or circuit with others, and cannot directly Obtain the same or similar system, program or circuit as its application by downloading from the Internet, modify the results of others, and at the same time, it is difficult to interact with third parties such as equipment suppliers
[0006] Before purchasing a programmable controller, users can only learn about the functions and performance of the controller in detail by reading manuals and other materials or downloading special software for installation and simulation; however, the amount of information obtained through graphic materials is limited, and it is impossible to understand the controller deeply However, the process of downloading and installing software is extremely cumbersome and has great information security risks, which does not conform to the trend of e-commerce.

Abstract

The invention provides an online simulation method and system of a programmable controller based on a web page. The online simulation system runs on a web browser, and simulates the appearance, control logic, user interface, etc. of the programmable logic device through JavaScript scripting language, html controls, etc., and the logic control program is written and stored by the user, and the interface is provided by the user. Change the operating parameters of the program and input information for debugging, and simulate the output status with sound and graphics; at the same time, establish a communication channel connected to the Internet and real devices for users to communicate with third parties in real time through the network and seek third-party assistance . Therefore, the user does not need real equipment and software installation, but only needs to download the online simulation system from the specified url on the browser, and then the simulation programming and debugging of the programmable logic controller can be carried out.

Description

technical field [0001] The invention relates to the computer field, in particular to an online simulation method and system of a programmable controller based on a web page. Background technique [0002] With the rapid development of microprocessor and computer technology, automatic control has gradually penetrated into almost all production fields. In this context, programmable logic controller (PLC) (hereinafter referred to as programmable controller) has been widely used; it is a simple computer dedicated to various types of machinery or production process control, which can be controlled by the user Customize the logic control program and store it in the internal memory, perform operations such as logic operation, sequence control, timing, counting, and arithmetic operations according to these programs, and control the frequency converter, stepper motor, water pump, water Valves, solenoid valves, cylinders, air pumps and other electrical equipment are controlled to real...
