系统投用10多年间，在装置开停车及异常工况或在用设备出现故障时，通常需要进行主、备机切换。操作主要以人工操作为主，操作过程风险大、强度高，控制精度难把握容易出现装置运行参数大幅波动或导致非计划停车，因此迫切需要一种智能切机控制功能，实现切机过程的自动化。有时候会存在快速把主备机切换完成，一旦出现在用机组设备故障，需要立即进行切机，减少装置运行风险，实现主备风机组一键全自动切机

During the more than 10 years since the system was put into operation, it is usually necessary to switch between main and standby machines in case of unit startup and shutdown, abnormal working conditions or failure of in-service equipment. The operation is mainly manual operation. The operation process has high risk, high intensity, difficult to grasp the control accuracy, and is prone to large fluctuations in the operating parameters of the device or unplanned shutdown. Therefore, there is an urgent need for an intelligent machine cutting control function to realize the automation of the machine cutting process. Sometimes, the main and standby units are switched quickly. In case of equipment failure of the unit in use, it is necessary to cut off the unit immediately to reduce the operation risk of the unit and realize the one key automatic cut-off of the main and standby air units
