Wireless City Fire Remote Monitoring System Design And Implementation Based On Internet Of Things

With the rapid development of science and technology,the links between various economic activities and objects and objects are more and more frequent.With the increase of fire numbers,the demand for real-time monitoring and remote monitoring of various fire fighting facilities in buildings becomes urgent.It is a work that must be put forward.The existing remote fire control system of the city has the intelligence and low degree of networking,and the duty personnel in the fire control room is high,which can not meet the demand for fire fighting work in modern society.Based on the technology of Internet of Things and NBIOT technology,this paper proposes the wireless city fire protection remote monitoring system,and the design of the wireless monitoring node of the sensing layer.The key technologies are studied.The main contents of the paper are as follows:The main contents are as follows:(1)the framework of wireless urban fire control remote monitoring system based on Internet of things technology is constructed,the wireless Internet of things monitoring node is designed,the urban fire control remote monitoring system is designed and implemented,the NB-IoT technology is studied,and all kinds of fire work state information in the building is collected and transmitted.(2)for the networked users of wireless urban fire remote monitoring system,a computer web page application program is developed to realize the functions of real-time monitoring,real-time alarm,real-time query,historical query,maintenance management,route guidance and user management.The system database is designed,and the entity relationship attribute diagram and database table of the system are introduced.(3)the hardware part of the fire remote monitoring system is designed,and each part is described in detail,including hardware selection and hardware circuit design,including hardware reset circuit,drive motor circuit and GSM communication circuit.(4)The system tests and tests the system core functions such as login and the user's addition and deletion,and the system performance test,and the test results show that the system operation achieves the expected effect.The main innovation of this paper is to propose a framework of wireless urban fire control remote monitoring system based on Internet of things technology,design wireless Internet of things monitoring node,mobile phone App and other key components,study NB-IoT technology,and realize the collection and transmission of all kinds of fire work statusinformation in buildings.This paper mainly designs and implements a remote urban fire control system.At the end of the paper,the system is tested.The test results show that the system can realize all the functions of fire control,and the performance of the system also meets the expected requirements.The system has great use value for the whole city fire control.
