在LHC运行1期间，紧凑型μ子螺线管（CMS）实验的运行控制系统中的许多操作程序已经自动化。当探测器高电压斜升或斜降时，或者在LHC的某些束流模式改变时，DAQ系统会自动地用新参数进行部分重新配置。某些类型的错误（例如由单事件扰乱引起的错误）可能会触发自动恢复过程。此外，顶层控制节点连续地执行交叉检查以检测由于配置密钥的改变、所包括的前端驱动器的集合的改变或由于潜在的时钟不稳定性而变得必要的子系统动作。操作员通过用户界面中相关命令按钮旁边显示的图形指示器进行必要的操作。通过这些指标，确保CMS配置的一致性。然而，手动跟踪指标有时仍然效率低下。因此，开发了一种新的操作员助手，可以以简化的顺序自动执行所有必要的操作。如果出现其他问题，新助手将尝试自动从这些问题中恢复。使用新的助手，只需单击一下，即可从子系统的任何状态开始运行。一旦选择了适当的恢复操作，可以通过单击恢复正在进行的运行。我们回顾了CMS Run Control的自动化功能，并详细讨论了新助手，包括第一次操作经验。
During Run-1 of the LHC, many operational procedures have been automated in the run control system of the Compact Muon Solenoid (CMS) experiment. When detector high voltages are ramped up or down or upon certain beam mode changes of the LHC, the DAQ system is automatically partially reconfigured with new parameters. Certain types of errors such as errors caused by single-event upsets may trigger an automatic recovery procedure. Furthermore, the top-level control node continuously performs cross-checks to detect sub-system actions becoming necessary because of changes in configuration keys, changes in the set of included front-end drivers or because of potential clock instabilities. The operator is guided to perform the necessary actions through graphical indicators displayed next to the relevant command buttons in the user interface. Through these indicators, consistent configuration of CMS is ensured. However, manually following the indicators can still be inefficient at times. A new assistant to the operator has therefore been developed that can automatically perform all the necessary actions in a streamlined order. If additional problems arise, the new assistant tries to automatically recover from these. With the new assistant, a run can be started from any state of the sub-systems with a single click. An ongoing run may be recovered with a single click, once the appropriate recovery action has been selected. We review the automation features of CMS Run Control and discuss the new assistant in detail including first operational experience.
