一种基于PLC的无损检测平台设计与实现

Design and implementation of a nondestructive testing platform based on PLC

鉴于当前我国在评价木材内部健康状况、建筑用木材内部形态等领域遇到的诸多难题,课题组开发了一种基于西门子S7-1200 PLC的无损检测平台。从机械结构、工作原理、控制系统硬件设计、控制系统程序设计以及人机交互界面5个方面,对无损检测平台进行论述与分析。开发的检测平台可以实现对木材的无损检测,具有稳定、高效、便捷等特点。

In view of the difficulties in evaluating the internal health status of wood and the internal shape of wood used in construction,the research group developed a nondestructive testing platform based on Siemens S7-1200 PLC.This paper expounds and analyzes the NDT platform from five aspects:mechanical structure,working principle,hardware design of control system,program design of control system and human-computer interaction interface.The testing platform developed can realize the nondestructive testing of wood,which has the characteristics of stability,efficiency and convenience.
