Lift is one of the most important transportation means in our daily life. It provides great convenience to the public especially for elderly and disabled person. However, poor levelling accuracy may cause serious bodily injuries to passengers. In order to improve the situation, we propose to develop a plug-and-use levelling alarm device for the aged lifts. The main features of this levelling alarm device are low product cost, low installation cost and instant alarm signal (both visual and audio) to the users.
Expected Outcome
This project aims to develop a plug-and-use levelling alarm device which is of low cost and can be adopted in over 25,000 lifts of age 30 years and above in Hong Kong. If the level difference between the lift car and the platform exceeds the pre-set value, the device will provide instant visual and audio alarm to alert passengers to prevent injury. The device will also use Artificial Intelligence for self-calibration of machine and perform Big Data Analysis on the trend of the levelling problems to provide useful information to the owners for considering lift modernisation.
Expected Trial Duration
