Control, Monitoring and Warning Computerized System for a Semi-Automated Sliding System of Assembled Roof

Faced by a need to overcome work force shortage and vanishing skill replacement, to avoid dangerous works and to reduce cost, a semi-automated sliding system of assembled roof is developed to build a roof of machine room within underground power plant. The semi-automated sliding system will improve working conditions, since it performs certain repetitive dangerous operation without fatigue and errors that often occur when workers perform these tasks. Of necessity here is a control, monitoring and warning computerized system to monitor the behavior of the assembled roof being slid; check whether its behavior is approaching its safety operating limits under operations; and automatically stop its behavior in emergency. First, this paper describes problems and motive in this study, Secondly, presented in detail is the implementation of the monitoring and warning computerized system being developed. Finally, the field evaluation and remarks are reported.
