Black screen operation
Thread Content
What is the concept and principle behind automated operation with a black screen in chemical plants these days?
No alarm was issued on the desktop; after a few minutes, the computer screen turned black. It operates in fully automatic mode, and if an alarm occurs, it exits this black-screen mode. Black screen mode can be used to evaluate the quality of operations, the level of automation, and so on. It doesn’t seem to be that many at the moment.
What systems or software does it consist of?
You may try moving this post to the petrochemical section; a small number of petrochemical companies are currently using this approach. Other industries are unaware of this.
As far as I know, no organization has yet been able to achieve true black-screen driving. The factors that influence this include: the design of the instrument system, procurement, installation (whether it is carried out in accordance with standards), routine maintenance, and the competence of the users; the configuration and setup of the DCS system; as well as the design and configuration of the SIS system. Implementing such systems requires significant investment, and results cannot be seen in a short period of time, which is why it’s not possible to achieve this goal
There are fairly advanced technologies, skilled operators, outstanding automation experts who are proficient in programming, as well as production equipment that offers reliable quality and stable performance. It is estimated that a black screen operation can be achieved.
From a system configuration perspective, during the initial stage of project design, what if optimization is carried out to achieve black-screen operation?
The key lies in the rigor and completeness of the control logic. By taking all possible scenarios into account and preparing plans for them, a high degree of automation can be achieved, with little to no need for human intervention – essentially operation without any visible interface.
This requires a very high level of automation, which is difficult to achieve in the chemical industry. Some industries in food and pharmaceutical manufacturing might be okay.
