基于反馈式可定位云台控制系统设计与实现

Addressed PTZ Control System Design and Implementation Based on Feedback

摘要:

在样品外观状况试验中,原值实时监测是发现检测对象缺陷变化不可缺少的手段,针对原值监测对样品应具备准确定位监测及信息可控的要求,在云台中建立了偏转角度检测装置,采集云台偏转角度脉冲信息并反馈到解码器中,对脉冲信号通过建立偏转角度计算公式处理云台偏转角度信息,并反馈给上位机,从而在上位机操作台、解码器、云台三者间形成了反馈式可定位云台控制系统;实践表明,通过这种反馈式偏转角数据的引入,上位机随时根据下位机反馈的云台偏转角数据实时监控云台工作状态,实现操作台对云台的精确控制,从而提高云台的易操作性和智能化水平。

Abstract:

In the test of sample appearance condition, the original value of real-time monitoring is an indispensable means for detecting defects changes of object , In view of the requirements that the original value monitoring of the information Should have accurate positioning monitoring and controlled information of sample, deflection angle detection device is built up for Pan-Tilt Zoom(PTZ), feedback deflection angle pulse information to the decoder, the pulse signal is processed by the establishes deflection angle calculation formula, then feedback to the host, thus work station in the upper machine (PC), decoder, together with Pan-Tilt constitute the feedback location PTZ control system, Practice shows that the introduction of this feedback deflection angle data, the upper machine (PC) can master PC instruction execution status at any time, according to the feedback data of Pan-Tilt deflection angle from the lower computer, precise control of PTZ is achieved, thus the operability and intelligent level of PTZ is raised.
