Development of an Internet virtual layout system for improving workplace safety

Digital Training and Advanced Learning in Occupational Safety and Health Based on Modern and Affordable Technologies

Occupational safety and health (OSH) is a very important issue for both practical purposes in industry and business due to numerous reasons, so a number of software, educational and industrial solutions are available. In this paper, the cloud-based mobile application for digital training and advanced learning in the field of occupational safety was presented. The proposed framework architecture was based on a novel approach: Node.JS for the server backend and the React Native for the front-end development; while MongoDB was used for implementing the cloud data storage using sensors that are all available on the Android platform. In the development of this application, a number of options were developed (using open-source software) such as the reading of a QR code, usage of built-in sensors within android platforms, reporting, and voice messages. The developed SafeST solution is presented through a real industry example. It emphasizes two main possibilities of the solution, improving OHS reporting and significant empowerment of the students in the OHS field based on the learning-by-doing approach. In this way, the additional engagement (identification, recording and reporting of UA/UC) of OSH managers has been reduced to a minimum, taking into account requested reports from management and authorities, and the continual training of the employees and preparation of the students for future working activities. The system was tested for educational purposes with the initial idea to develop an application for smartphones which could be useful and well adopted among engineering students in the OSH field.

An Interactive Layout and Simulation System of Virtual Factory

Traditional simulation systems were capable of providing statistical evaluation of targeted factory design feasibility. But designers cannot experience the actual setting of factory design and simulation. This paper illustrates the implementation of virtual factory layout system in 3D virtual environment. Two key techniques and functionalities are presented and visualized in our system. Based on the model database, designers can select proportionate physical object from database and interactive layout them in virtual factory. Furthermore, we define the logical model and establish the communication between logical models for simulation.
