We participated in the world elevator congress held in Langfang, China. International authorities and experts shared various lift and escalator code standards ; and regulations adopted in Asia-Pacific and America. Other topics such as lift operation during emergency evacuation and artificial intelligence were also presented. We would like to thank all the speakers for their knowledge sharing which have benefited all of us.
We participated in the Beijing-Tianjin-Hebei Elevator Engineering And Safety Development Forum 2019 held in Langfang, China on 24th April 2019. It was a fruitful sharing session with experts, discussing topics pertaining to lift safety, latest add-ons to support the safety requirements and the practical approaches to resolve lift breakdowns. We also shared many common views particularly on artificial intelligence (AI) vs human approach in identifying the causes of lift breakdowns.
In short, a good knowledge of elevators both theoretical and practical are essential requirements to resolve lift issues. For AI to be able to identify the root cause of lift breakdown, a substantial amount of data that matches the profile of the defective lift is required. Lifts with similar specifications may have different types of lift faults. The smooth operation of the lift system depends, not just on the electronic and control operation, but also on the proper installation of the lift. If the AI programmer does not have the required experience in interpreting the lift faults, the AI system may not be programmed correctly. This may lead to inaccurate lift diagnosis. Lift diagnosis cannot be solely determined by the frequency or probability of lift faults. Detailed engineering is required to identify the fault and solution to support the diagnosis.
Though a well programmed AI system is a good aid to support lift diagnosis, engineers and specialists cannot forgo the basics of engineering troubleshooting. With or without AI, they still need to have the necessary experience in handling lift breakdown through fundamental engineering methods such as analyzing the circuit system diagram and/or mechanical system ; and practical experience in troubleshooting through real time lift faults.
We were one of the 78 delegates in 11 countries who participated in the 8th Symposium on Lift and Escalator Technologies, held in Hong Kong from 15 – 16th May 2018. It was a great opportunity for us to learn from the best engineering practices and technologies globally as well as sharing our experiences and opinions on how we can raise the lift & escalator industry standards that comprise both safety and traffic management including engineering design, equipment maintenance and passenger operation. We would like to thank the Lift & Escalator Symposium Committee and the host city for their efforts to organise the event.
An article of the symposium was also featured in the “Elevator World” magazine in August 2018, Page(s) 158-160.
