Recent years, with the rapid development of the power system needs to improve, advanced and practical dispatching automation system to be guaranteed. To meet the growing highly intelligent real-time data acquisition, processing, monitoring and control automation systems require. Dispatching automation system usually contains a large screen integrated display system, which bear the main control system, Monitoring System Computer, network, centralized display video signals applied to different scales the control of power distribution system.
Systems make full use of ultra-high resolution digital mosaic wall, high-contrast display features, combined with GIS And GPS Powerful space management system capacity, accurate collection of multi-display system status and operation of electrical equipment real-time information, will provide the equipment location, power geographical distribution, information statistics, query, intuitive graphical display and management functions. Can partition or the entire screen display SCADA / EMS systems, transformer operation management systems, electrical goods and materials management system, DTS system, scheduling production management (DMIS) system, electricity billing system, GIS and GPS applications and other related information. Of the power system running the analysis, helping dispatchers to understand and master the power system operating state, to ensure network operation Security Nature of decision making for the scheduling of a modern, fast visual display means.
View of the high reliability of power distribution system for the special requirements of the professional projector manufacturer tend to have high resolution and high reliability Technology Used to carry out continuous daily work among projector manufacturers.
Order to make the projector more suitable for multi-screen rear-projection mosaic application for the type of projector manufacturers are often given special features:
A. color temperature adjustment function. The projection function of the continuous adjustment of image color temperature, or even the red, green and blue single color light to be adjusted. The characteristics of a single-screen display can be used to ensure the projected image and Monitors Exactly the same; in multiple projector display wall, it can ensure the screen and the screen the exact same color between.
B. lamp power conversion function. The projector's lamp power can be adjusted. General There are 3 modes: automatic brightness adjustment mode, the maximum brightness mode brightness mode and the economy. Users may need to decide their own. Automatic brightness adjustment mode is most important, in this mode, the sensor inside the projector will automatically Detect Projector's output brightness, and adjust the light bulb through the closed loop power control system in order to ensure the lifetime of the bulb, projectors can maintain a constant brightness output. This not only extends the lamp life, reduce operating costs, and splicing in a multi-screen applications to ensure the brightness between the screen and the screen is always uniform.
C. light features continuously improve the stability of its spectrum with the use of the image colors do not change time.
D. long-life light source designed to reduce operating costs. In addition to raising the brightness of the projector lamp, lamp life up to have more than 6,000 hours.
E. To ensure the projector has a high reliability machine, projector manufacturers in the design of various components to assure reliability. Currently, advanced projector, the average time to failure (MTBF) has more than 40,000 hours.
In the design and manufacture of dedicated multi-screen display wall projector, most manufacturers are drawn to rear integrated design not only saves space, but also easy to install. 127cm (50 inch) rear projection about the depth of integration of DLP projector is only about 67cm, is suitable for the use of space is very tight places.
Order to maximize the consistency of the screen wall projection screen, reducing the sense of isolation, the most advanced seamless technology is used, that each piece of the wall projection screen, no borders, from the front, with o screen close together, space is less than 1mm. However, seamless technology is often used to the environment temperature and relative humidity have more stringent requirements to ensure that no large deformation of the screen.
Choice for the screen, the key or select the high-gain wide-screen, this center of the screen up to three times the general gain to 5 times the horizontal angle can reach 180 , with good clarity and color reproduction for display high-resolution computer graphics and video signals.
