2、perative sensing and the ability to interpret data from the environment. In this paper, we propose a fire alarm system called firealarming system indoor environment (fasie), which innovatively integrates wireless fire alarm network with hand fire extinguishing rescue support system. Unlike tradition
3、al wireless sensor networks that implement fire networks, the fasie is able to fire into fire, including fire alarms, providing full range of services, firerescuing and Firefighter positioning. In order to explain Fahey better, we first give a general description of fasie and introduce the architect
4、ure of the system. Then, the hardware and system performance are introduced. Key words: Wireless Sensor Networks (WSN), indoor environment, fire alarm system, handheld fire rescue support system 1 Introduction With the new manufacturing and integration technology, reduce the cost, the size of the wi
5、reless sensor, we have witnessed another revolution, is conducive to the control and observation of our life and the physical world, as the network technology to do, micro sensors connected to each individual and organization deeply embedded into the physical environment of information exchange netw
6、ork we can observe with the environment and in a loyal, previously not real-time human-computer interaction. As one of the most influential aspects of fire protection applications, public safety activities have also achieved significant benefits in the emergence of wireless sensor networks and their
7、 further development in 2. In this paper, we propose a wireless fire alarm system fire alarm system for indoor environment (fasie) the main contribution is the introduction of the wireless network and handheld fire alarm fire rescue fire alarm and rescue support system to provide comprehensive techn
8、ical support. The rest of this article is organized as follows. Section 51.2 describes the state-of-the-art of existing fire alarm systems. In the 51.3 section, fasie is introduced from the point of view of system composition and function. The 51.4 section describes the fasie layered architecture. T
9、he 51.5 section introduces the key hardware of fasie. The 51.6 part analyzes the performance of fasie. Finally, conclusions and future work are presented in sect. 51.7. 2 related work Because wireless sensor networks have great potential in the field of fire protection, many fire protection systems
10、have been developed based on WSN. But in most cases, the only purpose of the network is to obtain environmental data, which are collected and displayed in a base station, stored in a database, or sent to a remote location 3,4. Here, several representative proposals differ from the traditional paradi
11、gm as follows: (1) CFFDRS 5 is a forest fire that has been extensively implemented in the United States and new zealand. The main component of the system is the fire weather index (FWD), and this index is the key meteorological element through the fire, such as temperature, evaluation of relative hu
12、midity, wind speed and precipitation. The acquisition of CFFDRS information relies on wireless sensor nodes deployed in thousands of forested areas. The CFFDRS monitoring network collects various information (e.g., temperature, wind speed, and humidity). The base station of the monitoring network pr
13、ovides environmental information directly to the remote server.(2) scier 6 is a comprehensive system for the detection, monitoring and prediction of natural disasters. Sciers target applications are urban and rural areas. The unique component in scier is the local alarm control unit, used to control
14、 the wireless sensor network (WSN) and is responsible for the early detection, location and subsequent fire alarm function of the fire. Scier develops wireless sensor nodes in two different urban and rural areas: citizens, masters, public sensors, sensors. The citizens of the owners, sensors, and se
15、nsors of public ownership, sensors, and installations are different, depending on their application scenarios. (3) Eidos 7 is a comprehensive system including alarm, fire alarm and rescue. The main component of the system is a network composed of thousands of sensor nodes, deployed in the field of u
16、nmanned aerial vehicles (UAV). Another key element of the system is the handheld device that firefighters carry. The network is responsible for monitoring the monitoring area and sending environmental information to remote servers. Handheld devices are integrated with lightweight browsers that have access to remote databases or data centers. In summary, although the sys
