Control System of High Pressure Nitrogen Generator Based on Embedded Controller

According to the characteristics of PSA nitrogen production technology and the shortcomings of the existing nitrogen generator, such as unable to operate under centralized control, low efficiency and high energy consumption. A high pressure nitrogen generator control system based embedded controller is proposed. The STM32F407ZGT6 microcontroller is selected as the control core, and carried out the software and hardware design. The purpose of reducing energy consumption and improving nitrogen quality is achieved by modifying the adsorption and regeneration time. The high/low pressure nitrogen pressure is monitored in real time through the sensor and the pressurization process is automatically carried out. Through the design of touch screen human-computer interface program, it can complete the functions of authority management, real-time data display, parameter modification and so on. At the same time, the system also has GPRS-based data upload and remote control functions. After testing, the system has simple operation, stable work, strong practicability, and meets the expected requirements.
