摘要
针对当前的大区域内火情监控以人工为主,实时性较差,报警存在延时的问题;在需求分析的基础上,设计并实现了一种基于嵌入式与GPRS技术的大区域火情监控系统,硬件平台以嵌入式S3C2410芯片配合温度传感器LM75A以及相关外围电路,采集处理传感温度信息,利用GPRS网络的大范围数据通信能力传递各种火情信息,软件采用了分层的设计思想,将整个系统的软件设计分为用户应用层、网络集成层、硬件驱动层3个层次结构进行设计,利用SMS的方式进行火灾报警,避免了人工检测时主观强,实时性差的弊端;系统经过大量的实际数据测试证明,误差率基本能够保持在15%以内,比传统算法,报警准确率提高了27.4%,大区域控制范围在1平方公里,报警性能良好,具有很强的实际应用价值。
In view of the current fire monitoring is given priority to artificial, poor real--time performance, alarm delay problems, on the basis of demand analysis, designs and realizes a kind of large area fire monitoring system based on embedded technology, GPRS technology in embedded hardware platform S3C2410 chip cooperate LM75A temperature sensors and related peripheral circuit, sensing temperature infor marion collection and processing, using GPRS network of a wide range of various fire message data communication ability, and the software adopts the hierarchical design thought, the software design of the whole system is divided into user application layer, network integration, hardware driver layer three layers structure design, fire alarm in the form of using SMS to avoid the subjective strong artificial detection, the disadvantages of poor real--time performance. System test and a lot of actual data show, it can keep within 15% error rate, better than the traditional algorithm, the alarm accuracy increased by 27.4%, large area control in 1 square kilometers, alarm performance good, has the very strong practical application value.
