GDS system
Thread Content
Dear seniors, each workshop has its own GDS cabinet, and these cabinets are connected to each other via fiber optics; all of them are displayed on an operator station in the central control room. Is that acceptable?
It can be said that it is possible to do it this way, but adjustments will likely be needed in the future. I’m currently working on a project in which, originally, the GDS systems of the entire factory were centralized in one control room for monitoring; but now each workshop needs to be monitored separately, with each workshop having its own independent GDS system
Flammable gas alarm system – I’ve been working on this as well recently. I was thinking of skipping the GDS; is that possible?
GDS cannot be skipped. If you want to get it right from the start, follow the DCS standards directly, even if it means using a low-quality domestic DCS system. It will save a lot of trouble in the future.
Take a look at WORKBENCH: the upper-level system is from Zhejiang University’s Zhongkong, while the lower-level system is WORKBENCH. In our factory, the GDS data is transmitted from the on-site cabinets to the central control room via fiber optics.
They were together before; why separate them now? Are there any regulatory guidelines?
Since I’m new, I can’t tell you what the standards are; it’s just a self-improvement initiative by the factory, not as a result of any issues being identified during an inspection. According to feedback, for large refineries, it is not practical to monitor so many workshops (along with separate plant areas and storage areas) from just one central control room; therefore, it was decided to implement a system where each workshop is monitored separately.
The GDS should be set up independently, and be completely separate from the entire system. It is intended only for alarm purposes, and an independent DCS or PLC can be used. To standardize the acceptance process, it’s better to have a separate set. Regarding the fiber optic connection mentioned by the poster, centralized display is also an option; many locations are too scattered.
