In a building should have a good security system,especially Emergency Exit (emergency evacuation path).Emergency Exit is important because when an emergency occursin the building, the first thing to do is get out of the lab building.One thing to note is the emergency exit door. With the emergencydoor that can be opened quickly so all workers can get outquickly as well from the building when an emergency occurs.So,we need a model (prototype) controlling an emergency door thatcan function properly in an emergency. Prototype newemergency door controller is expected to be implemented intoactual emergency door. Prototype can be accessed with a pushbutton by the user facility. The prototype controller usemicrocontroller ATMega16. And for each emergency exitmovement is monitored and its status is expressed in LEDindicator lights and LCD display on 16x2. Modeling controllingemergency exit of a series of tests using a prototype have workedwell except on the 3rd test caused an error when calibrating thedistance between Ultrasonic sensor with Emergency Door.

Abstract. One of the main problems of rescue workers in confrontation of fired complex buildings is the lack of sufficient information about the building indoor environment and their emergency exit ways. Building information modeling (BIM) is a database for building a 3D model of building information to create a 3D building geometry network model. This paper has implemented some GIS and BIM integration analyses to determine the shortest and safest paths to people under fire risk and simulate their movement in the building. Plasco building was a multi-story shop in Tehran which has been fired in 2017 and destroyed. This paper attempts to simulate the firefighting and rescue operations in Plasco Building using an integration of BIM and GIS. There is no detailed information about the building and the fire incident, therefore the developed BIM and corresponding geometric network might differ slightly. The shortest and safest paths to the exit door or windows where the fire ladders are located are computed and analyzed. As a result of 15 scenarios developed in this paper, it was found that at 87% of the cases, the safest paths for the emergency exit of the people at risk were longer than the shortest paths. This study has evaluated different scenarios for the shortest and safest paths using Dijkstra algorithm considering different origins and destination points in the 3D indoor environment to assist the rescue operations.

Fikri Musthofa, Heru Winarno, in this paper explain that along with the high number of accidents on the highway at this time of course must be a special concern for motorists. There are many factors that underlie the occurrence of an accident in driving, the most important of which is the factor of driver error in driving, such as drowsiness or lack of rest, lack of concentration, and much more. Besides the security system in vehicles is also very influential in reducing the number of accidents in driving. With the development of today's technology, it is necessary to create a speed deceleration system on the motor based on the distance to the barrier objects in front of the vehicle using ultrasonic sensors. Ultrasonic sensor which is a type of proximity sensor is a sensor that can detect distances so that it can be used as a sensor in this system. This system can reduce motor speed automatically when the sensor detects a barrier object in front with a distance of less than 300 cm. This system will be active when the ultrasonic sensor detects a distance of less than 300 cm. At that distance the Arduino Mega 2560 will adjust the PWM value of the motor, the motor PWM value will decrease 12% every second so that within a period of 8 seconds the motor will have a speed of 0 rpm which means the motor will stop. This system is expected to reduce the number of road accidents due to motorists' faults. Keywords: Speed Deceleration, PWM Method, Ultrasonic Sensor, Arduino Mega 2650.ReferencesAgus Setya Abadi, Delta. 2008.

Perimeter intrusion detection systems are an integral part of most physical security systems. Perimeter fencing is widely used to isolate and protect public and private places such as airports, military bases, power stations and security related applications. Fence structures merely prevent a percentage of intrusions or postpone them. A higher level of security needed to monitor and investigate activities on or around the university. Perimeter Intrusion Detection System (PID) focusing on the fence intrusions. The system used major components as Arduino board, 8x8 LED display, ultrasonic sensor, 16x2 LCD display module and speaker. The unauthorized person who tries to intrude the university would be sensed, detected and alarm would generate a signal that an intruder was trying to enter the university. The sound level depended on the distance, the nearer the intruder and stronger would be the alarm signal. PID system displayed the distance of the object or personal found in its region on the LCD display. This system was very useful for security applications. Ultrasonic sensor would be searching if there was a motion in its range.

AbstractDue to safety issues when passengers get on and off the subway and spend a lot of time on the subway, this makes subway station signs very important. Moreover, in case of fire and other dangerous situations and emergency evacuation, the guiding signs must be able to guide passengers to leave the station and dangerous areas efficiently and orderly, so as to protect the personal and property safety of passengers. The purpose of this study was to analyze the decision response of subway evacuation signs using the characteristics of the brain components. In this study, subway model is constructed. When you perform simulation using software, you need to fine tune the parameters to get the best simulation effect. A questionnaire survey was made on the components of the subway sign. The results show that the number of people who think that the standard font of the blackboard logo is the most representative of the emergency exit, accounting for 78.2% of the total number of people, taking the image as the first choice accounted for 52.9% of the total number of people, and the green sulfur powder logo as the first choice accounted for 69.8% of the total number. This study makes an important contribution to the research of subway traffic safety problems.

A simple model to handle the flow of people in emergency evacuation situations is considered: at every point x, the velocity U (x) that individuals at x would like to realize is given. Yet, the incompressibility constraint prevents this velocity field to be realized and the actual velocity is the projection of the desired one onto the set of admissible velocities. Instead of looking at a microscopic setting (where individuals are represented by rigid discs), here the macroscopic approach is investigated, where the unknown is a density ρ(t,x). If a gradient structure is given, say U = -∇D where D is, for instance, the distance to the exit door, the problem is presented as a Gradient Flow in the Wasserstein space of probability measures. The functional which gives the Gradient Flow is neither finitely valued (since it takes into account the constraints on the density), nor geodesically convex, which requires for an ad hoc study of the convergence of a discrete scheme.

This paper USES the probability analysis method, Markov model to predict fire personnel safety evacuation design rationality in public places. In a large public fire safety evacuation for example is analyzed, the results showed that: Markov model can be scientific, accurate and effective to predict the export flow density of the extreme cases within the limited time and emergency exit door set minimum traffic. In order to ensure the fire after the personnel to evacuate to the safe zone within the time allowed.
