Problems solved by technology
[0003] The communication between the existing experimental system and the computer adopts RS232 serial mode. Many notebook computers or desktop computers do not have RS232 serial interface, which makes the experimental system unusable. Some experimental systems use serial-to-USB modules designed by third parties. , can barely be used, but the performance is unstable. Once the connection fails, you must first shut down and then restart, which is extremely inconvenient to use and seriously affects the normal progress of the experiment; at the same time, when the existing experimental system communicates with the computer, the computer’s Most of the requirements are 32-bit operating systems, and there will be incompatibility problems on 64-bit operating systems
