An integrated type fire alarm control panel which is for the purpose of the ubiquitous environment application is reported. For the ubiquitous environments, mainly three additional functions upon its inherent capabilities are implemented. That is, wireless technology with ZigBee capability is applied for the interface of ZigBee detectors. Camera images can be displayed in the fire alarm control panel in which images are transferred via ethernet. For the time synchronization of the distributed fire alarm control panel, GPS module is introduced and implemented in the system.

The modular beam made of steel material is wholly responsible for the load stress of the structure, therefore securing the fire-resistant capacity of the steel beam is absolutely important. The economic efficiency achieved by minimizing the thickness of the fire-resistant board attached, is also essential at the same time. Accordingly, a study of optimization of the thickness and interval of fire-resistant boards shall be conducted side by side. Therefore, in this study we have anticipated fire-resistant capacity by using a general-purpose S/W for finite elements, ABAQUS(6.7.1), in order to propose the configurable conditions that can secure the optimal fire-resisting capacity of modular beam. As a result of this analysis, it was impossible to secure the fire-resistance capacity when directly attaching fire-resistant board(30mm) on the modular board in accordance with KS F 2257-1, and the fire-resistant boards were manufactured in shape of module in consideration of its installation interval rather than direct application.

On this research, we show some concrete examples as software design, 2D/3D display, graph display, and gage display to develop a data monitoring system for real time safe fire testing. Developed software which is simulation software for live fire testing, has been designed to display informations about whole test status in a live fire testing, and with this, user can control a live fire testing under the safe environment. Beside, we increase a security by using a authority of user to access on this software. and we develop it based on module designed to apply a requirement of user later on.

Buildings are becoming more and more high-rise and large-scale in recent years, so in the event of a disaster such as a fire, enormous human and economic damage is expected. Therefore, management, security, and fire control are essential for large buildings in the city. Because these large buildings are very complex outside and inside, they need a three-dimensional control based on 3D modeling rather than a simple flat-oriented control. To do this, this paper designed and implemented a building control system based on 3D modeling. Specifically, we designed a 3D building / facility editing module for 3D modeling of buildings, a 3D based control module for building control, and a linkage module that connects information such as firefighting equipment, electrical equipment and IoT equipment. Based on this design, a building control system based on 3D modeling was implemented.

A Through Bulkhead Initiation Module(TBIM) has been designed which guarantees the seal property without using O-ring. The TBIM works as the shock wave generated by a donor charge transmits to the acceptor charge. The structural safety of TBIM housing has been calculated via modeling analysis, and the ignition performance has been proved by 10 cc closed bomb test. The reliability analysis has been made using Probit method on the base of performance test results. According to the reliability analysis the bulkhead thickness of TBIM which is the most important design parameter has been determined.

In this paper, an experiment was performed to confirm the effectiveness and the reliability of the wireless fire detector with a 2.4 GHz wireless module which is widely used for commercial purpose. It was the experiment of transmitted waves of wireless signals using samples of typical obstacles such as walls which may affect the wireless communication environment in the building. The experiment results show that the transmitted signal had differences in the response characteristics by wall types.

Korea Gas Safety Corporation is developing consequence analysis system for combustible materials release events to enhance risk assessment technology and its efficiency. Unlike general consequence analysis programs, the final consequence area was implemented through ETA analysis based on API-581 standard, and a convenient user interface was constructed based on HTML5-based responsive web technology. In addition, a phase equilibrium module using third-order state equations (such as Peng-Robinson, SRK, and RK) and fugecity was implemented to analyze the mixture quality. Also. using the consequence analysis algorithm introduced in CCPS books and TNO Yellow Book, we developed material leak analysis module, fireball, pool fire, jet fire, flash fire, and vapor cloud explosion consequence assessment module. In addition, the conditions for calculating the safety distance were prepared with using the control values in the EIGA standard, PAC, and Bevi Reference Book.

To provide pleasant building environment and the ease of maintenance and facility management, many new office buildings are being built as intelligent buildings. Building control systems which are employed in intelligent buildings require advanced types of controllers and varieties of control schemes. Designing and installation of these types of advanced building control systems take a lot of effort and also they are costly. In order to design these systems, it is necessary for the designers to have means to analyze and estimate the performance of control systems. The simulator which is presented in this paper is composed of three parts, HVAC simulation module, elevator simulation module, and evacuation modeling module for the outbreak of fire or similar disasters. In this paper, the functions and modelling method for each module are explained and simulation results are presented.

This paper deals with the paddle type end of arm tool for rescue robot instead of rescue worker in dangerous environments such as fire, earthquake, national disaster and defense. It is equipped at the dual arm manipulator of the rescue robot to safely lift up an injured person. It consists of the paddle for lifting person, sensors for detecting insertion of person onto the paddle, sensor for measuring the tilting angle of the paddle, and mechanical compliance part for preventing incidental injuries. The electronics is comprised of the DAQ module to acquire the sensors data, the control module to treat the sensors data and to manage the errors, and the communication module to transmit the sensors data. After optimally designing the mechanical and electronical parts, we successfully made the paddle type end of arm tool and evaluated its performance by using specially designed jigs. The developed paddle type end of arm tool is going to be applied to the rescue robot for performance verification through field testing.
