Problems solved by technology

However, because it uses a single-chip microcomputer or X86 CPU, the data acquisition accuracy is low, the control performance is poor, the control loops cannot be smoothly transitioned, and it is difficult to realize the three-closed-loop control. Many peripheral devices are supported, which leads to increased volume, high cost, and poor maintainability; in addition, due to the use of RS232 serial communication, the communication rate is low and the real-time performance is poor
