摘要
电视监控系统是一种典型的分布式计算机信号采集系统。为了提高监控的范围和效果,云台控制器的优劣直接影响监控的范围和效果,因此对云台控制器的设计具有重要的意义。本系统采用串型通信,通过Modbus协议把控制信号输入单片机,经过对AT89S52单片机的编程,从而对八路继电器输出进行控制。系统不仅结构简单,而且还可以方便的对镜头、防护罩的控制进行扩展,功能强大,可以广泛应用于电视监控系统中的云台控制。
TV monitoring system is a typical distributed computer signal acquisition system.The quality of Haeundae controller directly effects the scope and results of monitoring,so the design of Haeundae controller is of great significance.The system uses string-based communication,through the Modbus Protocol to control signal input SCM,after the AT89S52 MCU programming,then control the eight-way relay output.System is not only simple structure,but also convenience of the camera,protective mask to expand the control and powerful,can be widely used in television monitoring system in Haeundae control.
