摘　　要：为了对注型机生产过程中存在的异物残留、滑块错位、脱模不良等异常情况进行实时监控,以满足对注型模具的自动保护,设计并实现了一种基于DM6437微处理器的新型模具保护系统。使用Candence软件完成了DSP控制板高速电路部分的仿真及其硬件设计,考虑到实际生产中现场噪声、阴影以及机械振动造成的图像偏差,设计了基于FAST-9快速角点检测的匹配算法,以完成图像的实时配准,并与传统的模板匹配算法进行了比较,最后通过实验验证了硬件系统的可靠性和软件算法的有效性。A new mold protection system based on a DM6437 microprocessor was designed and implemented for injection molding machines. For mold protection, this system was designed to have the function of performing the realtime monitoring of an injection molding machine＇s abnormal situations of process residues, slider dislocation and other badness during its producing. The simulation of a part of the system＇s highspeed circuit on the DSP core board and the design of the system＇s hardware were accomplished by the Candence. Considering image offset caused by the noise, shadow and mechanical vibration, an efficient registration algorithm based on the FAST9, a fast comer detec tor, was applied to realizing the image registration, and then it was compared with the SAD （ sum of absolute differ ence） algorithm. The experimental results show that the hardware of the system is stable and the algorithm is effec tive.
