摘　　要：针对入场汽车煤人工采样方式劳动强度大、单纯的人为操作机械采样装置很难控制入场煤弄虚作假等问题,文章介绍了一套入场汽车煤智能采样控制系统的设计。该系统由车厢定位选点子系统、采样点坐标转换子系统、现场控制子系统、数据库子系统和通信子系统组成,采用数字图象处理技术和改进的模糊边缘检测算法实现车厢自动定位选点,采样点坐标经转换处理后,由PLC完成现场自动采样控制。实际应用表明,该系统精度高,可靠性好,操作简便,能满足实际需要。Aiming at the problems that labor intensity of manual sampling way for entree truck coal was great and only human operating mechanical sampling equipment was difficult to control falsification phenomena of entree coal, the paper introduced design of a intelligent sampling and control system for entree truck coal. The system is composed of carriage positioning and siting subsystem, coordinate transformation of sampling points subsystem, field control subsystem, database subsystem and communication subsystem, adopts digital image processing technology and improved fuzzy edge-detection algorithm to realize automatic positioning and siting of carriage and field automatic sampling control is completed by PLC when coordinate of sampling points is transferred. Practical application showed the system has high precision, good reliability, convenient operation and can meet practical need.
