This paper applies China-made PLC to the refueling control system,and the China-made ChaoYu large IL40 series PLC is selected as the main control device.The CPU redundancy,link redundancy,IO redundancy,and power supply redundancy are designed to improve the continuity,stability,and reliability of the control system.The test results indicate that the redundant mechanism can be used to keep the system running normally when some faults occur.The error of refueling time and volume of the system is smaller than those of the Siemens system,and PLC performance is comparable to that of Siemens.The system can operate automatically during the refueling process and has precise control over the speed and flow rate of refueling.The system operates stably and reliably,meeting the control and reliability requirements of the refueling system.
