Zusammenfassung:The invention aims to disclose a control method for realizing equipment interlocking according to an equipment operation current signal, which comprises the following steps of: (1) realizing by DCS (Distributed Control System) logic configuration, when the current of operation equipment is lower than a set value, delaying or after the operation equipment fails, sending pulse interlocking to start standby equipment logic; (2) normal operation of the system can not be influenced by operation equipment faults; compared with the prior art, cables do not need to be laid, any hardware does not need to be added, interlocking starting can be achieved only through logic configuration when equipment breaks down, normal production is not affected, the monitoring workload of personnel can be reduced, and the purpose of the invention is achieved. 本发明的目的在于公开一种根据设备运行电流信号实现设备联锁的控制方法,包括如下步骤:(1)通过DCS系统逻辑组态实现,运行设备电流低于设定值时,延时或者运行设备故障后发脉冲联锁启动备用设备逻辑;(2)运行设备故障可不影响系统正常运行;与现有技术相比,无需敷设电缆、不增加任何硬件,仅通过逻辑组态即可实现设备故障时的联锁启动,不影响生产正常进行,还可减少人员监
