Abstract

In the industrial and network monitoring field, there are several protocols such as Pelco D/P used for remote operation and widely applied to control the pan/tilt/zoom (PTZ) camera systems. But for universal CCD camera, a lot of incompatible communication protocols have be developed by different manufacturers. To extend these cameras' application in remote monitoring field and improving its compatibility with controlling terminal, it's necessary to design a reliable protocols conversion module. This paper aimed at realizing the conversion and recognize of different protocols for CCD camera. Protocol conversion principle and algorithm are analyzed to implement instruction transformation for any camera protocols. An example is demonstrated by converting Protocol Pelco D/P into Protocol 54G30 using Micro Controller Unit (MCU). High performance hardware and rapid software algorithm was designed for high efficient conversion process. By means of serial communication assistant, Video Server and PTZ controlling keyboard, the stability and reliability of this module were finally validated.
