【摘要】：目前管道检测仪器仪表种类繁多,采用各种原理和复合技术的仪器快速发展,也要求对使用者给予培训,掌握其使用要领,提高操作技术水平,提高管道泄漏检测水平,为管道运行和维护提供可靠的技术数据。系统由上位控制计算机和现场信号控制板卡构成。上位计算机是一台台式计算机或者一台便携式笔记本,台式计算机置于室内,为系统的远程控制端;便携式笔记本使用灵活,可以置于室外现场,方便出题与考评工作的协调进行。现场信号控制板卡主要有通讯系统、信号控制器和信号发生器组成。其中通讯系统由RS-485有线模块和Zig Bee蜂窝移动通讯模块构成,用来实现远程有线和无线控制泄漏点信号的功能;信号控制器基于STM32F103ZET6芯片开发,通过芯片的I/O输出控制每一个泄漏点泄漏信号的状态和强度;信号发生器基于STM32F103ZET6,通过PWM信号的输出,经过低通滤波器产生目标的正弦波形,最后经过功放输出泄漏信号。运行在上位控制计算机上的远程控制软件,基于Windows操作系统,使用Visual Basic开发工具开发,具有远程控制现场泄漏点信号和学员成绩数据库管理功能。其中远程控制现场泄漏点信号主要分为随机设置和手动设置两种功能;学员成绩数据库管理利用Visual Basic的OLE组件管理控制Excel表格处理文档,实现学员信息的管理和成绩录入功能。埋地金属管道防腐层缺陷检测仿真系统经过实验室的功能调试和现场实地使用测试,各项功能均已实现,在现场实地测试中通过了经验丰富的测试人员的测试,并且连续可靠运行24小时,取得了成功。
[Abstract]:At present various pipeline inspection instrument types, the rapid development of instruments using a variety of principle and composite technology, is also required to give training to the users to master the using method, improve the technological level of operation, improve the level of pipeline leak detection technology, to provide reliable data for pipeline operation and maintenance. The system consists of host computer and field control signal control board. Host computer is a desktop computer or a laptop, desktop computer in the room, for the remote control system of portable terminal; the use of flexible, can be placed in the outdoor scene, coordinate with the title appraisal work convenient. The field signal control board are mainly composed of signal communication system, controller and communication signal generator. Cable communication system consists of RS-485 module and Zig Bee cellular mobile module, used to achieve the remote line and have no Control the leak signal; signal controller STM32F103ZET6 chip is developed based on the control of every leak leakage signal of the state and strength through the I/O chip output; signal generator based on STM32F103ZET6, the output PWM signal, sine wave low-pass filter produced from target, finally through the amplifier output signal. In the operation of leakage the remote control software on the computer, based on the Windows operating system, using Visual Basic development tools, with remote control on-site leak signal and student score database management function. The remote control on-site leak signal is divided into random set and manually set the two functions; student achievement database management using Visual OLE management module the control of the Basic Excel form processing documents, implementation of student information management and record function. The buried metal pipe The simulation system of defect detection and Simulation of the anticorrosive coating has been realized through laboratory function debugging and on-the-spot field test. All the functions have been realized, and in the field test, the experienced tester has been tested, and has been running reliably for 24 hours, and has achieved success.
