区块链在公共消防应急服务中的应用及研究

Application and Research of Blockchain in Public Fire Emergency Service

针对公共消防应急服务存在不可预见性、及时性、服务透明度和信任的问题,把区块链技术应用到公共消防应急服务中,以公平地实时处理公共消防应急服务请求,该系统包括三层:基础设施层、边缘层和区块链层。使用边缘计算服务器,以提高本地数据处理速度和数据存储。探讨了智能城市不同分区下智能家庭的基于区块链的物联网智能城市安全可信公共消防应急服务模型。实验结果表明,所提出的系统模型能够有效地将公共消防应急服务请求调度到合适的公共消防应急服务部门,并最大限度地减少到智能消防传感器位置的延迟。

There are some problems in the public fire emergency service,including unforeseen situations,timely service realization,service transparency and trust in public fire emergency service.The research applies blockchain technology to public fire emergency services,so as to handle public fire emergency service requests in a fair and real-time manner.The system consists of three layers:infrastructure layer,edge layer and blockchain layer.Edge computing servers are used to improve local data processing speed and data storage.The paper explores a blockchain-based IoT smart city secure and trusted public fire emergency service model for smart homes under different partitions of the smart city.Experimental results show that the proposed system model can effectively dispatch the smart home public fire emergency service requests to the appropriate public fire emergency service and minimize the delay in reaching the smart home location.
