The high and low temperature alternating test chamber controllers are all based on embedded system research and development, and have obvious geographical distinction. European and American companies prefer to use the WinCE embedded system as the controller's operating system, while Asian companies prefer to use the Linux embedded system as the controller's operating system. The advantages and disadvantages of the two controller embedded systems of high and low temperature alternating test chamber are as follows: Embedded Linux has the following advantages over WinCE: Embedded Linux has the following weaknesses compared to WinCE: Article source: Beijing Yashilin Test Equipment Co., Ltd.

1. Linux is open source and has a high degree of development freedom. WinCE is a non-open OS, which makes third-party product customization costly.
2, Linux kernel is relatively small, high efficiency; and WinCE system is more bloated, taking up too much RAM, the application is also relatively large.
3. Linux not only supports x86 chips, but also a cross-platform system. So far, it can support 20 to 30 kinds of CPUs, develop products with Linux environment, and almost never suffer from changing platforms.
4, Linux in the design of the kernel structure to consider the requirements of the system can be reduced, Windows CE in the design of the kernel structure and consider the height of the system can be reduced.
1. Linux system application software development is difficult and requires high technical strength; WinCE platform can use most of Microsoft's programming tools, such as Visual Basic, Visual C++, etc., and because of the high popularity of Microsoft programming tools, Most applications can be used on the WinCE platform with a simple modification and porting.
2, Linux core debugging tools are not complete, debugging is not convenient, there is no good user graphical interface; and WinCE inherits the traditional Windows graphical interface, achieving HMI is very simple.
3. Although the simplified Linux takes up less memory, its stability is still relatively different from that of WinCE.
4. Some Linux applications require virtual memory, and there is no or no virtual memory in the embedded system, so not all Linux applications can run in the embedded system.
