欧洲核子研究中心的大型强子对撞机于2015年重新启动，质心能量更高，为13TeV。预计在接下来的几年里，瞬时光度将显著增加。在紧凑型Muon螺线管实验中部署了升级的1级触发系统，以保持与前一次运行中实现的搜索和精确测量相同的效率。该系统由100个电路板组成，通过3000个光链路级相连，必须通过软件进行一致性控制和监测，运行效率高。本文介绍了用于控制和监测升级后的一级触发系统的软件框架的设计，以及使用该软件调试升级系统的经验。
The Large Hadron Collider at CERN restarted in 2015 with a higher centre-of-mass energy of 13TeV. The instantaneous luminosity is expected to increase significantly in the coming years. An upgraded Level-1 trigger system has been deployed in the Compact Muon Solenoid experiment, in order to maintain the same efficiencies for searches and precision measurements as those achieved in the previous run. This system consists of the order of 100 electronics boards connected by the order of 3000 optical links, which must be controlled and monitoring coherently through software, with high operational efficiency. In this paper, we present the design of the software framework that is used to control and monitor the upgraded Level-1 trigger system, and experiences from using this software to commission the upgraded system.
