Smooth migration, worry free! We offer a "three-step worry free upgrade":
- free system evaluation and customized solutions;
- Program intelligent conversion tool+protocol adaptation gateway;
- Staged debugging, key nodes for nighttime construction. Multiple customers have achieved "simultaneous production and upgrade", reducing comprehensive operation and maintenance costs by 35% and extending system lifespan by over 8 years.
Born specifically for strictness! The circuit board is coated with three anti paint and industrial grade wide temperature element devices, which have undergone -40 ℃ cold start and 70 ℃ high temperature aging tests. Batch application in northwest mining areas, coastal salt spray environments, high dust workshops and other scenarios, with a failure rate lower than the industry average of 50%, truly "able to withstand and rely on".
The dual rack redundant CPU architecture is the core! Real time synchronization of data between the primary and backup CPUs, with a fault switching time of less than 100ms (imperceptible to the human eye), coupled with MRAM non-volatile memory, ensuring that the program is not lost during power outages. We have been operating stably for over 5 years in multiple multi million ton steel mills, with annual downtime approaching zero, safeguarding the core productivity of the enterprise.
