摘要:

针对建筑垃圾中烧结砖块和混凝土块的混合物的分离难题,介绍了一种基于色选技术的建筑垃圾自动化分选系统软硬件设计实现及其实验验证。该系统基于机器视觉求取传送带上目标烧结砖块的质心坐标的方法,通过在上位机上编写相应的C++算法程序,利用OPC客户/服务器模式和PLC进行通讯,以实现对高压气阀的实时控制。为了提高系统的实时性,采用了环形队列数据存取方式。最后介绍了通过计算目标物的质心坐标,以实现其精确的定时和定位。实验结果表明：在传送带速度为1.00m/s时,分拣系统的识别率为96.8%,分选率为91.7%。烧结砖块和混凝土块高效分离回收后的经济价值将得到极大的提高,有助于解决目前城市固体建筑垃圾围城的环境难题。

Abstract:

Aiming at the problem of separation of the mixture of sintered bricks and concrete blocks in construction waste, this paper introduces the design of hardware and software of construction waste automatic sorting system based on color selection technology and its experimental verification.The system is based on the machine vision to get the center of mass of the target block on the conveyor belt, By writing the corresponding C++ algorithm program on the PC , using the OPC client /server mode and PLC (programmable logic controller) to communicate,so as to achieve real-time control of high-pressure air valve. In order to improve the real-time system, using a circular queue of data access mode. Finally,It is introduced that by calculating the center of coordinate of the target to achieve its precise timing and positioning. The experimental results show that the recognition rate is 96.8% and the separation rate is 91.7% when the conveyor speed is 1.00 m/s.The economic value of the efficient separation and recovery of sintered bricks and concrete blocks will be greatly improved, which will help solve the current environmental problems of the siege of solid municipal solid waste.
