Problems solved by technology
[0003] In the existing technology, whether the remote operation station on land can connect to the signal of the offshore platform is used as a basis. Once the monitoring equipment used in typhoon mode detects that the connection on the land is interrupted, it will directly trigger the SIS of the offshore platform to execute the shutdown procedure, resulting in the inability to achieve effective shutdown. stop, ultimately affecting production
If the satellite signal is only briefly interrupted, such as 10s, it will trigger the SIS to execute the shutdown procedure, which will lead to invalid shutdown

Embodiment Construction
[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of this application.
[0038] The core of the present application is to provide a method, device and medium for triggering effective shutdown of SIS, for triggering effective shutdown of SIS.
[0039] figure 1 It is a signal architecture diagram of an offshore platform. Such as figure 1 As shown in Fig. 1, a remote operation client is deployed on land, and the signal is sent to the offshore platform remote communication server of the offshore platform through a dedicated satellite li...

The invention discloses a method and device for triggering effective shutdown of an SIS and a medium, and relates to the field of industrial control. According to the method, firstly, a heartbeat signal of a remote operation station located at a land end is obtained, and in a typhoon mode, when the received heartbeat signal is interrupted and the interruption time is longer than or equal to preset time, a shutdown execution signal is fed back to an SIS so as to trigger the SIS to be shut down. According to the method, when a received heartbeat signal is interrupted and the interruption time is greater than or equal to the preset time, a signal for executing shutdown is fed back to the SIS to trigger the shutdown of the SIS. Therefore, in the method, the SIS is not immediately triggered to be shut down after the interruption of the heartbeat signal is received, so that the invalid shut down of the SIS can be prevented.
Description
technical field [0001] The present application relates to the field of industrial control, in particular to a method, device and medium for triggering an effective shutdown of an SIS. Background technique [0002] The production environment of some industrial site users is on the offshore platform. Under normal circumstances, personnel are required to control the distributed control system (Distributed Control Systems, DCS) and safety interlocking system (Safetyinstrumentation System, SIS) system to manage production on the offshore platform. But there is a typhoon season every year, and the typhoon season is when people need to be evacuated from offshore platforms. In this case, remote monitoring is carried out through satellites. When the signal is interrupted, in order to ensure that the offshore platform has a typhoon mode, once the signal with the land is interrupted in the typhoon mode, the SIS system needs to execute the shutdown procedure and shut down the production...
