带钢表面缺陷检测仪通讯接口的设计与实现
Design and Realization of Communication Interface for Strip Surface Quality Inspection Instrument

某镀锌生产线新增带钢表面缺陷检测仪，该设备是目前具有国际领先地位的带钢表面质量检测装置，可为镀锌线表面质量分析与决策提供数据依据。该设备与现有产线控制系统无通讯接口，因此亟待设计与实现该功能。本通讯接口与产线PLC系统和PCS系统均建立通讯，以西门子系统底层通讯Libcom为基础，分别获取产线信号点和钢卷信息，同时，将该设备处理完成的缺陷信息上传至大数据平台，实现数据的存储与共享。程序用C++语言编写，该接口设计通讯稳定，传输速度快，灵活性强，基本满足了该镀锌产线的使用需求。
A new strip surface quality inspection instrument is added to a galvanizing production line. This equipment is an internationally leading strip surface quality detection device, which can provide data basis for surface quality analysis and decision-making of galvanizing line. The equipment has no communication interface with the existing production line control system, so it is urgent to design and implement this function. This communication interface establishes communication with the PLC system and PCS system of the production line. Based on the bottom communication Libcom of Siemens system, it obtains the signal point and steel coil information of the production line respectively. At the same time, it uploads the defective information processed by the equipment to the big data platform to realize data storage and sharing. The program is written in C++ language. The interface design has stable communication, fast transmission speed and strong flexibility, which basically meets the use requirements of the production line.
