Research On Telecommunication Line Thrust Robot System Based On Machine Vision

For the telecom operator and the maintenance organization of telecom special network, line test is a high intensity and repeatability work. The existing hand held ADSL test instrumentation is inefficiency with low accuracy, and require experienced operators, therefore can not realize automatic test and remote test. It is urgent to develop an automatic line thrust system with high accuracy and fix the above problem. Utilize the available hardware to the demand, a telecommunication line thrust robot system based on machine vision is designed to realize the automatic line thrust in telecommunication field.This paper designs the whole machine vision based thrust line test robot, including control system and hardware configuration. Calibration and auxiliary image processing are used to realize orientation. Calibration is used to achieve approximate orientation of the line and image processing technology is used to achieve its accurate orientation. The combination of the two technology realize the pull and plug action of the line. With PC as the core, the upper computer of the system is developed by VC++6.0 and images of the line is acquired by CCD and image acquisition card. Image acquisition algorithm is developed according to the actual situation. The lower computer uses motion control card as the core to realize the direction control of X, Y and Z of the step motor. The system can be remote controlled through network using TCP/IP protocol. Tests are also conducted according to the actual need.The telecommunication line thrust test robot based on machine vision has been successfully developed and applied in telecommunication field. It not only solves the problem of available broadband equipment which can not thrust line and, but also provide a unified parameter standard for fix network communication line test. At the same time, the application of the robot reduces the cost and response time. Test results also indicate that the system developed in this paper can accomplish the test work of the assigned line with 98% accuracy. It is a effective and reliable line thrust equipment and has a good application prospect.
