A Simulator for the Design and Evaluation
of Elevator Safety Systems
ABSTRACT
We developed a simulator to evaluate the safety of elevator. This simulator includes a dynamic model with a normal state and some abnormal states and a safety logic model. These models are described with a state transition model. This report outlines this simulator, and we show its effectiveness paring the simulator's results with experimental results.
KEY WORDS Safety System, Elevator, Simulator, State Transition Model
1. INTRODUCTION
We developed a simulator to evaluate safety of an elevator. There are some simulators which
simulate the dynamics of an elevator [1] [2]. These have a model that shows when the elevator is normal or has a specific error. There are no simulators which can simulate the state transition of an elevator. A transition of the dynamic characteristics of an elevator according to the operation of the safety logic has a high level of influence in terms of elevator safety. To accurately evaluate safety of an elevator, we need a simulator that can continuously and precisely simulate the state transitions of a running elevator. Therefore, we developed a
simulator bines a safety logic simulation model and a dynamic simulation model, which
expresses the consecutive transitions of states of the elevator. Using this simulator allowed us to
precisely express the continuous transitions of an elevator
This simulator posed by the following state transition models.
(1) Dynamic
simulates
simulation model: this precisely the continuous transitions of a running elevator's state.
(2) Safety logic simulation model: this simulates safety logic operations according to the continuous
