Core technical advantages: First, intelligent micro-lubrication system, adopting oil-gas micro-lubrication technology, which can automatically and accurately control the lubrication amount according to the elevator operation times, car load, ambient temperature, and guide rail friction state. The lubrication amount per time is controlled at the level of 0.01ml, avoiding the shaft pollution and car slipping problems caused by excessive lubricating oil dripping, and the utilization rate of lubricating oil reaches more than 95%; Second, laser high-precision wear monitoring, equipped with high-precision laser displacement sensor, which can real-time monitor the wear amount, straightness and parallelism of the guide rail working surface, with a monitoring accuracy of ±0.01mm, automatically record wear data, generate wear trend curve, and early warn the hidden dangers of abnormal wear and deformation of the guide rail; Third, AI predictive maintenance, built-in AI algorithm, which can predict the remaining service life of the guide rail according to the guide rail wear data and operation data, automatically generate a maintenance plan, remind maintenance personnel to adjust and replace the guide rail in time, and realize "early warning and early disposal"; Fourth, environmentally adaptive design, the system can adapt to the wide temperature environment of -20℃~60℃, adapt to different application scenarios such as high-rise, super high-rise, heavy load, severe cold, high temperature, etc., with waterproof, dustproof and anti-vibration design, adapting to the complex operating environment of the elevator shaft; Fifth, convenient installation and strong adaptability, adopting modular design, no need to modify the original structure of the elevator, adaptable to all brands and models of elevator guide rails, the installation cycle is no more than 2 hours, and the lubrication status and wear data can be viewed remotely through the IoT platform, realizing remote monitoring and management.
