The Building Research Of Wireless Network Fire Detection CPS Based On Multi-Agent

With the development of network and information technology, people have the higherrequirements for the fire early detection and the accuracy of the detection in intelligent building.Moreover, with the increase of the intelligent of modern buildings，the amount of datatransferred in the network also are increased. The issues of data transmission conflict in thenetwork and the real-time and accuracy of fire detection being affected emerge. So we need toimprove the real-time, reliability and validity of network transmission to ensure the real-timeand accuracy of fire early detection. The topic puts the technologies of Multi-Agent, wirelessnetworks, data fusion theory and the concept of CPS as the support and combines with thecharacteristics of the modern intelligent building environment to design the architecture,wireless network architecture, the software and hardware of the wireless Network fire detectionsystem based on Multi-Agent. And, the paper also studies data fusion algorithms andcommunication protocols of the system. Through the above research, improves accuracy andreliability of the fire early detection, and makes important theory and the application results.In this paper, the main contents include the following:(1) Research the theory, characteristics and features of Agent and Multi-Agent, and researchthe technical characteristics of the wireless network. The paper puts the wireless networktechnology as the support to research and design the wireless network fire detection systembased on Multi-Agent. And we put it apply in intelligent building environment.(2) The paper researches the theory of cyber physical system(CPS), puts the Agent theoryapply in the design of each node of the system, and uses the CPS thought to design thearchitecture model of the wireless network fire detection CPS based on Multi-Agent. Betweenthe same types of Agents use the blackboard structure to communicate.(3) The paper combines the intelligent building environment and the characteristics of thesystem to design the hardware architecture of the system and introduce the system functions,through a combination of both to achieve the modular design of the system. This can effectivelyimprove real-time and reliability of data transmission, thus improve real-time and accuracy ofthe fire early detection and reduce the rate of fire misstatement and under-reporting.(4)The paper designs hardware circuit of the system, and part of the software has beenachieved, and design the wireless network topology based on the specific circumstances ofintelligent building fire detection environment and the system architecture. The paper alsodesigns the communication protocol of the system based on Zombie technology, ensures thereal-time and reliability of data transmission.(5)Based on intelligence, autonomy and social characteristics of Agent, the paper uses D-S evidence theory algorithms for data fusion, then comparing the fusion results with the havingset threshold to see if there was a fire. The paper uses simulation software fuse the collection ofdata. The simulation results show that the more the number of fusion, the higher the rateaccuracy of early fire detection.(6)The topic introduces the theory, framework structure and each layer of norms of Zigbeeprotocol. Based on Zigbee technology, the topic also researches and designs the communicationprotocol of the system that is wireless network fire detection CPS based on Multi-Agent.
