Research On The Design Of Intelligent Fire-control Supervision And Alarm Processing Systems

With the substantial increase in urban electricity equipment and population intensity,the probability of fire is increasing and the harm caused by the fire is also increasing.Nowadays,the large number of fire systems in society is still inadequate,such as: the wired transmission of the fire information collection,the need of personnel scheduling in on-site escape and so on.In this paper,the demands of intelligent fire alarm system in modern society are investigated and analyzed.The analysis results show that the achievement of large-scale distributed fire monitoring,multi-mode alarm,escape induction and other functions is necessary.Advances in modern technologies such as electronics,communications,and computers provide technical support for the implementation of these functions.The overall design scheme of intelligent fire alarm system is proposed in this paper.In this scheme,fire monitoring sensor nodes are arranged in multi-area and multi-site,and a wide range of distributed fire monitoring is implemented using the same set of network data servers and data processing systems.The large-screen display on duty room,mobile phone text messages,remote information push and other multi-way alarms are achieved.And the functions of inducing escape are achieved by using the lower computer(single-chip)to drive display module and Dijkstra algorithm to calculate the shortest path.The information collection system is designed in this paper,including a fire detection system and a wireless transmission system.The fire detection sensor and the passive infrared sensor information is transmitted to the data server in real time.In particular,when the passive infrared data is valid,it indicates that there is a need to be rescued on the site to guide the rescue operation.The system also uses GPRS wireless transmission technology to achieve the remote transmission of fire data,so that the use of the system can be used without geographical restrictions.The intelligent fire comprehensive information management system is designed in this paper,and the Oracle database is constructed.The system implements the fire location,early warning and query function,and the user interface is friendly.Finally,the fire alarm processing system,the bell alarm,elevator landing,textmessages sent,escape induction,fire scene video display and other functions are designed,and the alarm processing are achieved automatically.The system innovatively applies the Dijkstra algorithm to the fire escape induction scenes.The test results show that under the premise of following the national standard,the intelligent fire control system can achieve the real-time collection of fire information,the wireless transmission of fire information,the timely alarm and the quick escape at the scene.And the expected design goals of the fire alarm system are achieved.The innovations of this paper are as follows:(1)The overall design scheme of the intelligent fire alarm system presented in this paper has realized new functions;(2)This system innovatively applies Dijkstra algorithm to the fire escape guidance of corridor model.
