Introduction
RGVs losing connection mid-run and stopping for half an hour — on ceramic storage lines, this isn’t an occasional glitch; it’s a daily reality for many factories. High temperatures, dust, electromagnetic interference, plus incompatible communication protocols between different equipment, turn a fully automated production line into one that frequently stalls, waiting for network recovery.
This case comes from a Foshan ceramic manufacturer with a kiln line over 300 meters long. With KAXA’s wireless solution, they achieved 6 months of zero communication failures, 99.99% equipment online rate, and a 25% increase in blank transport efficiency.
Background
A ceramic manufacturer in Foshan operates a kiln line over 300 meters in length. The company upgraded to an automated storage and handling system, enabling “unmanned transport, precise storage, and coordinated scheduling” of ceramic blanks from the forming workshop to the kiln entry. However, frequent communication interruptions between system modules, delayed equipment status feedback, and lagging dispatch commands severely constrained production efficiency.
Challenges
The ceramic storage line faced particularly acute communication pain points:
- Inconsistent Communication Protocols: Transport equipment, storage equipment, and inspection/control equipment used different communication protocols, making data exchange difficult and creating “information silos.” Without a unified communication standard, real-time coordination between modules was nearly impossible, leading to frequent miscommunication and production delays.
- Harsh Environment: High temperatures (locally reaching 45°C-60°C), heavy dust, and strong EMI near the kiln line caused frequent failures of standard equipment. Standard commercial networking gear simply couldn’t survive the extreme heat and dust — components degraded rapidly, leading to constant replacements and unplanned downtime.
- Mobile Equipment Roaming Dropouts: RGVs and stacker cranes experienced long handover times and frequent dropouts when moving across zones, resulting in lost dispatch commands and disrupted continuous production. Each dropout meant the RGV would stop mid-operation, requiring manual intervention to restart — a process that could take 30 minutes or more per incident.
Solution
KAXA built a stable, efficient, and anti-interference communication network tailored to the automated storage and handling system:
- RGV/Stacker Wireless Communication: KXC1100-5N industrial wireless clients were installed on RGV onboard controllers, supporting 802.11r/k/v fast roaming protocols to complete AP handovers within milliseconds — ensuring uninterrupted command and data transmission between RGVs and the dispatch center during operation. This eliminated the “stop-and-wait” delays that previously plagued the system.
- Full-Area Wireless Coverage: KXA5100-5N industrial wireless APs were deployed at high positions on both sides of the aisle, with carefully planned spacing to ensure ≥30% signal overlap, providing ample buffering for RGV roaming handovers. This overlapping coverage design ensures that as an RGV moves from one AP’s coverage zone to the next, there is always a strong signal available — no dead zones, no sudden drops.
- Industrial Ring Network Backbone: KXS308G industrial switches were deployed to form a redundant ring network architecture, capable of automatic failover to backup links within 50ms in case of main link interruption — ensuring continuous network availability even during unexpected cable cuts or switch failures.
- Device Data Interconnection: KXN2210 serial device servers were installed in conveyor motor control cabinets to convert RS485 to Ethernet, translating motor operating parameters and sensor status signals into standard TCP/IP protocol data, eliminating information silos. This unified all equipment communication into a single standard, enabling seamless data flow across the entire production line.
- Centralized Network Management: All network components are managed through the KX-WLC5508 wireless controller, providing the facility’s IT team with a single pane of glass for monitoring, configuration, and troubleshooting — significantly reducing response time to any network events.
Results
- The system achieved 6 months of zero communication failures with 99.99% equipment online rate — maintaining zero packet loss and zero latency during peak production. Production no longer stops due to network issues.
- Information silos were eliminated, enabling real-time data exchange and coordinated operation across all modules, with blank transport efficiency increased by 25%.
- Stable communication links and real-time fault alerts reduced troubleshooting time, with unplanned downtime reduced by 40-50%.
- Equipment lifespan in high-temperature zones extended significantly, reducing replacement frequency and maintenance costs.
- The IT team now proactively monitors network health through the centralized controller, identifying potential issues before they impact production.
Customer Testimonial
“Our RGV used to lose connection mid-run and stop for half an hour. Now with 6 months without a single communication failure, production has been incredibly stable. The system just works — we don’t have to think about it anymore.”
