Large Cloud Mirror Camera Control System Design And Implementation,

Camera integrated with large-size pan/tilt and lens is an important front part of videomonitor system. It is widely used in the following outdoor environments: bad weatherconditions, strong electro magnetic interference conditions and large sences etc. This papermainly discusses a method of design and implemention of controlling system topan-tilt-zoom camera. The primary work of this paper includes:◆According to specific requests, based on a single chip processor, the writer givesa total low-cost scheme of the design and implemention of pan/tilt and lenscontrolling system;◆Then the writer distinguishly discusses the method of realization of the modulesin the controlling system, including pan/tile control module, protocoltransforming module, lens communicating control module, and design peripheralcircuit and software process of each module;◆Using an on screen display chip, the writer designs and realizes a dynamiccharacter superimposition module for the controlling system. It can be used inhighway video monitoring system for overlapping time, date, address and chinesecharacters that needed. It greatly improves the work efficiency of the monitorsystem operators. It can also be transplanted and expanded for more applications.This paper designs and realizes a large-size pan/tilt and lens controlling system,including a character superimposition module. It costs little, so it's suitable for industryapplication. It can be a reference of front device in security monitoring system.
