Power quality monitoring device is a long-term continuous, real-time and online monitoring device with various and comprehensive power quality parameters. From the aspect of software platform, Linux system is adopted.

       Linux is a popular open source operating system. Many hardware and software manufacturers design and develop products using Linux operating system. As a professional power quality monitoring device manufacturer, Linux system is also used in software design mainly because of its several characteristics.

1. Linux system is free software. Linux system is free software through GPL.

2. Good portability of hardware platform. Hardware platform portability refers to that when the operating system is transferred from one hardware platform to another, only a small amount of code at the bottom needs to be changed without changing its operation mode.

3. Fully comply with POSIX standard.

4. It has a good graphical user interface.

5. It has powerful network function. Because Linux system is developing rapidly on the Internet platform, it also has powerful network functions.

6. Rich application programs and development tools.

7. Good safety and stability.

Just because Linux has the above characteristics, the power quality online monitoring device products can be modified and improved according to the needs of customers or the site when designing the software platform to ensure the high reliability of the software system.
