摘要
设计一种通用云台控制器。系统以新型单片机P89V51RD为核心,硬件设计采用RS 485通信专用器件MAX 485和新型感性负载专用驱动芯片ULN2803,软件采用模块化设计思想,实现对图像监控系统中多种云台以及摄像机和监控现场辅助设备的控制。新型单片机、专用通信和驱动器件的采用简化了系统硬件结构、提高了整个系统的性能和可靠性。经测试通用云台控制器性能稳定、兼容性好。
A universal PTZ controller is designed in detail. The hardware system is implemented using P89V51RD,new inductive load drive chip ULN2803 and communication chip MAX485. Then introducing modularization, software is developed. It realizes the different PTZs, the cameras and auxiliary equipments which can be controlled in image supervisory control system. Adopting new type MCU and the special IC,the hardware system is simplified and the whole performance is increased. Experimental results indicate that the new high quality PTZ controller system is simplicity,stability and compatibility.
