Abstract:Under the background of the?requirement?of?the national information security with independent controllable weapon electronic equipment, a Local Monitoring and Control System is developed. According to the functional requirements and communication interface requirements of the system,the system requirements are analyzed,the scheme of the monitoring system based on Loongson processor and NeoKylin operating system is introduced,the principle of domestic hardware design,software framework,development process of interface driver,surface design method are described,the domestic monitoring system, realize four way CAN totaled 3600 frames per second,1400 IO acquisition points by Ethernet,it has cross platform portability,reusability and scalability.It was confirmed by the experimental results,the system owns communication redundancy and reliability,high surface and background execution efficiency and stability,the environmental adaptability meets the requirements of electronic equipment engineering,it improves the independence and controllability of Supervisory Control And Data Acquisition system,with popularization and application value for the design and operation of independent controllable system.
