The normal operation of deaerator provides water for steam generator. The stability of deaerator liquid level is of great significance to ensure core cooling. This paper introduces the principle of three-impulse control of deaerator level controller, and analyses the system response and response measures under abnormal input parameters of deaerator level controller. The main function

Action analysis is an important method to improve production line. Taking the assembly line of a company’s body radio frequency controller as the research object, the operation time of the production line’s bottleneck position was measured by the method of time measurement (MTM). The problems in the production process were analyzed and found. Aiming at

Based on MSP430F169 single-chip computer, Hall sensor, LCM12864, IR2130 special MOSFET chip, the brushless DC motor control system is composed of electric vehicle. The MSP430 C program is written into MSP430F169 chip, and the PWM signal is generated by the built-in timer of the single chip computer to realize voltage regulation. The position signal of

In the past, PLC control and computer control have always been the two main control modes in industrial control. In the past, the process of monitoring the state of construction machinery by PLC control system is complex and time-consuming, thermostatic element which makes the working efficiency of construction machinery low and difficult to meet the

At present, there is a general contradiction between the demand for enterprise talents and the cultivation of university talents in China’s higher education, which reflects the separation of theoretical teaching and practical teaching in teaching. This paper takes Electrical Appliances and Programmable Controller as an example to discuss the application of project-driven teaching mode. This
