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。Aiming at the problem of separation of mixture of sintered bricks and concrete blocks in the construction waste,this paper introduces the design of prototype implementation of a construction waste automatic sorting system based on color selection technology and its experimental verification.Machine vision approach is adopted to get the mass center of the target block on the conveyor belt,By performing the corresponding color selecting algorithm on the computer and using the OPC client/server mode and PLC(programmable logic controller)to communicate,the real-time control of high-pressure air valve is achieved.To improve the real-time performance,a circular queue of data access mode is employed.Finally,the precise timing and positioning is carried out by calculating the center of coordinate of the target.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 benefits will be greatly improved after the efficient separation and recovery of sintered bricks and concrete blocks.At the same time,it will help solve the current garbage siege problems.
