【摘要】：智能电网是当今世界电力系统发展变革的最新动向,被认为是21世纪电力系统的发展趋势。智能电能表及其配套设备所组成的高级量测体系是智能电网建设的关键之一,因而智能电能表的质量将影响到智能电网建设的成效。在此背景下,智能电能表的质量一致性问题日益受到关注。质量一致就是要求中标的智能电能表和现场运行表的质量状况一致,包括PCB(印刷电路板)质量、电能表软件质量和电能表材质质量。智能电能表PCB的一致性是表计质量一致性的关键部分。随着生产技术的不断提高,PCB技术向着高精度化、超细微化和多层化方向发展,加上智能电能表的需求日益增大,建立一套能够对智能电能表PCB的一致性进行快速批量自动比对的检测系统显得尤为重要。本文首先列举当前常用的PCB自动检测技术,通过比较分析选择应用AOI技术,采用基于分级模板匹配的PCB检测算法。然后提出五轴联动控制子系统开发智能电能表的PCB一致性检测系统,设计系统的总体架构,并对系统的核心部分进行详细叙述,即五轴联动控制子系统和基于分级模板匹配的PCB板检测算法。五轴联动控制子系统作为智能电能表的PCB一致性检测系统硬件的关键部分,使摄像机不仅能够对PCB进行平面扫描,还能通过定位台实现PCB的X,Y及Z轴方向移动和水平旋转、摆动,即五轴运动,从而进行侧面和多角度扫描,提高检测系统的能力和精准度。基于分级模板匹配的PCB板检测算法用于实现快速可靠的图像识别和匹配。系统研发完成后应用于实践,并通过测试,分析存在问题,提出解决方法。
[Abstract]:Smart grid is the latest trends of development of power system reform, is considered to be the development trend of power system. The amount of twenty-first Century advanced intelligent electric energy meter and its supporting equipment consisting of the measuring system is one of the key smart grid construction, so the quality of the intelligent electrical energy table will affect the construction of smart grid in this effect. Under the background of quality consistency problem of intelligent electric energy meter is attracting more and more attention. The quality is consistent with the requirements of the intelligent electric energy meter line and on-site operation table quality, including PCB (printed circuit board) the quality of electric energy meter power meter software quality and material quality. The consistency of the intelligent electric energy meter PCB the table is a key part of quality consistency. With the continuous improvement of production technology, PCB technology with high precision, ultra fine and multi direction, and the intelligent electrical energy table of increasing demand, establish a Capable of quick detection system of automatic batch alignment consistency of intelligent electric energy meter PCB is particularly important. This paper lists the commonly used PCB automatic detection technology, through the comparative analysis of selection and application of AOI technology, using PCB classification detection algorithm based on template matching. Then put forward the consistency of PCB detection system for five axis control the development of intelligent electric energy meter system, the overall system architecture design, and the detailed description of the core part of the system, namely the five axis control subsystem and PCB plate classification detection algorithm based on template match. The key part of five axis control system as an intelligent electric energy meter PCB conformance testing system hardware. The camera can not only scan on the PCB plane, but also can realize the PCB positioning stage by X, Y and Z axis movement and rotation, swing, five axis motion, thus in the side The PCB board detection algorithm based on hierarchical template matching is used to realize fast and reliable image recognition and matching. After completion of the research and development, the system is applied to practice, and through testing, problems are analyzed and solutions are put forward.
