摘　　要：为消除ADS 25 MeV超导质子直线加速器在束流调试、运行过程中误触发现象,主要对其机器保护系统软件进行优化设计.通过优化底层FPGA和上层LabVIEW程序,增加三选二表决机制的判断逻辑相关代码,提高了数据传输的可靠性和保护动作判断逻辑严谨性,彻底消除了系统的误触发和误动作现象.In order to eliminate the phenomenon of false trigger during beam tuning and operation of ADS 25 MeV superconducting proton linear accelerator,we optimized the machine protection system software.By optimizing the underlying FPGA and upper LabVIEW program and adding three-choice and two-vote mechanism and the judgment of related logic codes,we not only improved the reliability of data transmission and the logic rigor of protection action but also completely eliminated the phenomenon of false trigger and false action of the system.
