Solution for safety monitoring system of cable crane

1. Industry pain points

​Three major operational risks need to be addressed urgently​

• ​The terrain span leads to blind spots in supervisionThe ropeway often crosses hills and canyons, with the spacing of the supports exceeding 100 meters. The operation sections above 90% cannot be monitored in real time, and the position of the materials is "out of contact" throughout the process.
• ​Overloading operations cause safety hazardsSimple ropeways generally lack weighing devices. Under high-load transportation, the weight of goods is not supported by data, which accelerates the wear of steel cables and doubles the risk of overturning.
• ​The ability to position the entire process is lackingThe current equipment only supports local observation. Construction personnel cannot obtain the progress of material transportation in real time and rely on manual visual inspection, with a response lag rate of over 70%.

2. Solution

​All-domain intelligent monitoring system​
"Build""Centimeter-level positioning +AI security protection + remote centralized controlThe Trinity System

• ​Full-trajectory precise trackingThe Beidou satellite RTK positioning technology is adopted to capture the three-dimensional coordinates, speed and time data of the running trolley in real time, with an error of no more than 3cm.
• ​Five-level security guarantee mechanism​：
  • Dynamic anti-collision warning
  • Infrared personnel intrusion identification in the loading/unloading area
  • High-definition video surveillance of gantry (supporting remote view adjustment)
  • Real-time feedback of the load-bearing cable/traction cable force
  • Overload automatic disconnection protection
• ​Intelligent operation and maintenance management hub​：
  The new energy power supply system ensures a 30-hour battery life in rainy and cloudy weather
  Real-time transmission across multiple 5G/4G terminals (PC/ mobile phone/large screen)
  The centralized console enables one-click scheduling of all equipment along the entire line
