Abstract

The utility model discloses a printing quality monitoring system, belonging to the technical field of a computer control. The monitoring system consists of a host computer, a display screen, a monitoring hand piece, a sensor, three changeable camera lenses, a DV, a light source 1, a light source 2 and an intelligent exploitation board. Wherein, the monitoring hand piece is arranged the right upper part of a high speed running tested object to be vertical to the high speed running direction. The sensor is vertically arranged on the gear wheel on the device, whenever the sensor comes close to any gear of the gear wheel, the sensor generates an impulse signal. The impulse signal is transmitted to the hoist machine after being processed by the intelligent exploiting board. The host machine then processes the image and displays the image onto the display screen. The system can carry out real time on line monitoring operation the high speed running objects. The observed images are very clear and the color restoring level is fairly high. The image and the color are closely similar to the real object effect at best so as to facilitate to waste judging. Therefore, the production efficiency is improved, the product quality is controlled, the work intensity is reduced and so is the cost. A plurality of systems can be connected with the network to more intelligently manage the people and the objects.
