DCS系统和基于DCS系统的延迟焦化焦炭塔顺序控制系统
摘要：
本发明公开了一种基于DCS系统的延迟焦化焦炭塔顺序控制系统和DCS系统，该控制系统包括：处理装置（20），被配置成执行与焦炭塔相关联的顺序控制过程；接收装置（10），被配置成从多个现场设备接收信号，并将该信号传送到所述处理装置（20）；其中，所述顺序控制过程分成按顺序的多个操作步骤，在该多个操作步骤中的一个操作步骤中，在所述处理装置（20）指示了操作并通过所述接收装置（10）接收到指示所述多个现场设备中的至少一个现场设备完成该操作的信号时，所述处理装置（20）才开始执行下一个操作步骤。
摘要（英）：

The invention discloses a delayed coking coke drum sequence control system based on a DCS and the DCS. The control system comprises a processing device (20) and a receiving device (10), wherein the processing device (20) is configured for executing a sequence control process associated with coke drums; the receiving device (10) is configured for receiving signals from multiple field devices and transmitting the signals to the processing device (20). The sequence control process is divided into multiple operating steps in sequence. In one of the operating steps, only when the processing device (20) indicates operation and receives the signals indicating at least one of the field devices to complete the operation through the receiving device (10) can the processing device (20) start to execute the next operating step.
