目前,随着生活水平的提高,人们对自身居住环境的要求也越来越高,除了舒适便捷外,安全性更是首要考虑的问题。针对如今大多数小区普遍安装的固定方向监控摄像头监视效果常常不尽如人意的问题,提出一种借助单片机、热释电红外传感器实现的自动跟踪监视系统设计方法。 At present, with the improvement of living standards, people’s requirements for their living environment are also getting higher and higher. In addition to being comfortable and convenient, safety is the primary consideration. Aiming at the problem that the surveillance effect of the fixed direction monitoring camera, which is commonly installed in most of the communities, is often unsatisfactory, an automatic tracking and monitoring system design method based on a single chip microcomputer and a pyroelectric infrared sensor is proposed.
