With the advancement of intelligent computerised buildings in recent years, there has been strong demands for intelligent elevator control with more sophistication and diverse functions. The design criteria of an intelligent elevator control system would include optimising the movement of a group of elevators with respect to time, energy, load, etc. In this paper, a new elevator group superviso...
An elevator fault diagnosis method based on Sequential Probability Ratio Test (SPRT) is proposed in this paper. In order to verify the effectiveness of the method, this paper designed the fault diagnosis experiment for elevator mechanical system. Firstly, the wavelet transformation is used to filter the noise of the vibration signal collected in the experiment. Then the kurtosis value of the fi...
A fairly general model of the elevator system is presented. Coloured Petri Nets (CPN) and CPN tools are adopted as modeling tools. The model, which is independent of the number of floors and elevators, covers different stages of the elevator system in substantial detail. The model assists simulation-based analysis of different algorithms and rules which govern real elevator systems. The results...
this paper studies the extension mechanisms of the UML in the object oriented application and it introduces a new approach of using Stereotypes and shows its usefulness by implementing in an elevator control system. This paper also discusses the process of specifying, translating and verifying UML specifications for an elevator system. Different kinds of existing UML Meta-models used in an elev...
Background and Objectives: Work-related injuries are considered as the third cause of mortality across the world and have been introduced as one of the health, social and economic risk factors amongst industrial and developing communities. The present epidemiologic survey aimed to assess the work-related accidents among Iranian workers who were insured by the Social Security Organisation . ...
background: there is a high prevalence of occupational injuries due to accidents in construction industries which affect human health. therefore, the exploration and analysis of contributing factors of such accidents can lead to their prevention and the reduction of their consequences. this study was conducted with the aim to identify factors related to occupational injuries and the severity o...
