摘要
针对目前管道在线监测用电功率大、网络通信不稳定和系统时间不同一的缺陷,设计了一种基于嵌入式PC104的管道泄漏检测定位系统。应用GPS授时技术和局域网连接中心PC与远程监测终端,详细分析了其系统检测原理、硬件结构和软件设计方案。通过实际测试和应用表明:该系统运行稳定,低功耗,且保证了远距离数据传输的完整性、可靠性和实时性,能够对管道泄漏进行正确的识别,并做出准确的定位。
Aiming at the shortage of large power consmnption, unreliable network communication and different system time on pipeline online monitoring, a new oil pipeline leakage detection and positioning system based on embedded PC104 is designed. Use the GPS time service technology and LAN between central PC and remote terminal unit. The detection principle, hardware structure and software design of the system are introduced in detail. The test and actual application show that the system operates stably, and its power consumption is low and integrity, reliability and real-time performance of remote data transmission is guaranteed. It is able to correctly identify the pipeline leakage, and nlake accurate positioning,
