Abstract
Lift industry is a field that is mechanical, electrical and electronic technology and constantly requires inspection and maintenance considering various applications and various types. Recently, various lift control and monitoring technologies with IT are developing for lifts on land. But technologies with IT have been hardly done in ship’s lift that is consistently assured safety and reliability of life cycle for its parts in poor environment. Unlike general lifts, ship’s lifts should be able to operate reliably in rolling and pitching according to the operation of the ship. except the stop button operation by hand.

In addition, it has been designed and operated to withstand marine environments that are worse than general land lifts, as it has to satisfy specific performance requirements such as dust, vibration, shock, electromagnetic waves and noise on board.

However, the PLC-based lift which is limited to the simple function of lift operation control has no safety related control and monitoring system. In this paper, we implemented embedded main cotroller, floor controller and car controller that meet the requirements and use NMEA network protocol by analyzing home and abroad integrated lift operation and management systems. Especially, we secured reliability of maintenance by real-time fault diagnosis and control that was implemented with limit switch, gyro sensor, temperature / humidity / barometric pressure sensor and fire detection sensor thinking over the environmental conditions of terrestrial and ship’s lift. The remote safety diagnosis and maintenance system for maritime lift introduced in this paper is based on real - time remote safety diagnosis based on marine - land maritime broadband communication based on real - time remote diagnosis and quick maintenance system, which enables rapid maintenance, reduction of maintenance cost, And establishing a formalized safety inspection system.
