Abstract

Conventional fire fighting robots are controlled by a remote control to monitor the fire scene or to suppress the fire. However, this method has a problem that it takes a long time to prepare robot and input it to fire place in the golden time after the fire, so that it can not sufficiently serve as a fire fighting robot. Using the autonomous driving fire monitoring robot, when a fire signal is generated, in conjunction with a fire receiver a moving robot takes a video of the fire scene and delivers the image to the fire department, so that the fire fighter can decide if it is real fire or not. Thereby it is possible to prevent a sudden spread of an accident by providing a quick judgment opportunity and at the same time suppressing the fire early. In this paper, we propose an architecture of the autonomous mobile fire monitoring robot and the communication protocol required for the robot to work with the fire receiver. A communication protocol is designed to control multiple fire monitoring robots in real time, and a communication with a fire receiver is designed as a hierarchical network to serve as an interface of an Ethernet network using wireless Wi-Fi. The fire monitoring robot and the wireless communication of the fire receiving period are implemented and the effectiveness of the operation is confirmed through the field test.

기존의 화재 관련 소방로봇들은 원격조종기로 제어되어 화재현장에서 화재 상황을 감시하거나 화재를 진압하는데 사용되고 있다. 그러나 이러한 방식은 화재 발생 후 골든타임 안에 로봇을 준비하고 투입하는데 많은 시간이 소요되어 소방로봇으로서의 역할을 충분히 다하지 못한다는 문제점을 가지고 있다. 자율 주행 화재감시로봇을 활용하면 화재수신기와 연동하여 화재 신호 발생 시 출동한 로봇이 화재 현장의 동영상을 촬영하여 방재 담당자에게 영상을 전달함으로써 실제로 화재가 발생했는지 또는 오보인지를 확인 할 수 있도록 정확하고 빠른 판단 기회를 제공하고 동시에 화재를 초기 진압함으로써 대형 사고로 확산되는 것을 방지할 수가 있다. 본 논문에서는 자율이동 화재감시로봇의 구성과 이 로봇이 화재수신기와 연동하는데 필요한 통신 프로토콜을 제안한다. 실시간으로 다수의 화재감시로봇을 제어할 수 있는 통신 프로토콜을 설계하며 화재수신기와의 통신을 무선 Wi-Fi를 이용하여 이더넷 네트워크의 인터페이스 역할을 수행하도록 계층적 네트워크로 구성한다. 설계하는 화재감시로봇과 화재수신기간의 무선통신을 구현하고 필드시험을 통하여 동작의 유효성을 확인한다.
