【摘要】：石油天然气的运输方式主要是管道运输。腐蚀是影响管道工作效率及寿命长短的重要因素,腐蚀不可避免,怎样缓解腐蚀速率是经久不衰的话题。目前被广泛应用的做法是对管道添加内外防腐层与采用管道阴极保护技术,两种措施相辅相成,共同维护管道的安全,减缓腐蚀速率,保证运输安全,杜绝资源浪费与环境污染,通过对管道阴极保护参数的采集来反应管道腐蚀程度,评价管道防腐级别是保证管道安全的重要环节之一。各类管道阴极保护参数采集系统技术日趋成熟,但未被广泛应用,因为部分系统在实际应用有一些问题有待解决。大多数地区还是采用人工沿线巡检的方式。传统的管道阴极保护数据采集传输系统虽然能满足采集与传输的功能,但部分存在采集覆盖面不广、耗资大、不能实现远程控制的问题。为扩大传统管道阴极保护参数采集系统的采集覆盖面积,实现远程控制数据收发功能。本文通过对目前应用于管道检测的各种方法及管道阴极保护理论的分析,设计基于NRF905与GSM的数据采集传输系统。系统由9组1对14的由多种功能模块构成的分机与结点机组成的星型网络构成,并通过多点跳频方式与上位机进行通信,通过短信与通话可实现远程控制功能。本文主要介绍系统结构组成,硬件设计与软件开发流程。测试结果表明,系统中9组1对14的星型网络数据采集传输系统运行稳定,通过手机短信或通话可以实现远程控制功能。
[Abstract]:The transportation mode of oil and gas is mainly pipeline transportation. Corrosion is an important factor affecting the working efficiency and life span of pipelines. Corrosion is inevitable. How to alleviate the corrosion rate is an enduring topic. At present, it is widely used to add inner and outer anticorrosion coating to pipeline and adopt cathodic protection technology of pipeline. The two measures complement each other to maintain pipeline safety, slow down corrosion rate and ensure transportation safety. To eliminate the waste of resources and environmental pollution, it is an important link to ensure the safety of pipeline by collecting the parameters of cathodic protection to reflect the corrosion degree of pipeline and evaluate the anticorrosion grade of pipeline. All kinds of pipeline cathodic protection parameter acquisition systems are becoming more and more mature, but they have not been widely used, because some of the systems have some problems to be solved in practical application. Most areas still use manual inspection along the way. Although the traditional data acquisition and transmission system for pipeline cathodic protection can satisfy the functions of acquisition and transmission, some problems exist such as the acquisition coverage is not wide, the cost is high, and the remote control cannot be realized. In order to expand the coverage area of the traditional pipeline cathodic protection parameter acquisition system, the remote control data transceiver function is realized. In this paper, a data acquisition and transmission system based on NRF905 and GSM is designed by analyzing various methods used in pipeline detection and the theory of pipeline cathodic protection. The system is composed of 9 groups of 1-14 star network composed of multi-function modules and node computers. The system communicates with the host computer by multi-point frequency hopping mode. The remote control function can be realized by short message and communication. This paper mainly introduces the system structure, hardware design and software development process. The test results show that the star network data acquisition and transmission system of 9 groups 1 to 14 runs stably, and remote control function can be realized by SMS or phone call.
