Multimedia central control device oriented system design of the soul, focused lighting, machinery, projectors and video and audio controls on the - body, provide users with a simple, straightforward control scheme, so that users can easily grasp the entire space environment of each device the status and function. The whole system central controller core. It is to control the bus and each device coupled to receive the control requirements manipulators issued, then the control device and the controlled device sends control commands to each extension. All control functions via a dedicated system software programming from the big screen to talk about multimedia, specific control via control panel or an ordinary PC implementation. Its user interface according to the actual requirements of the user, set to be intuitive and easy to understand (all Chinese, the graphics module), op. Control effect: ◇ according to the need to control the operation of various types of video and audio equipment (such as various function adjusts the projector, such as brightness, contrast, computer / video screen conversion, control video recorder functions such as play, fast forward, fast reverse, pause, stop, record, video and other functions, and set up the device and other senior adjustments); ◇ according to the need, through various professional matrix and related equipment control, to complete the handover of various types of audio / video / computer signals adjust the signal path; ◇ through the volume control box to complete the volume control; ◇ relay controller, complete electric curtains, electric screen control and electromagnetic lock switch and energize one through the glass of control; ◇ the central control device can be with different needs and design programs, such as sales of various lighting modes, dimming rate, password protection rights and other multimedia big screen, with the actual use of on-site adjustment. According to the specific needs of more large-screen multimedia users, preparation of operating procedures linked, only one command will be able to complete a number of actions. Composition 1. Multimedia PC machine (MPC) is the clearest explanation of the multimedia computer multimedia large-screen multimedia computer before, the traditional personal computer or information processing machines is often limited to text and numbers, can only be regarded as the initial stage of computer applications, Meanwhile, the way the interaction between man and machine only through the keyboard and monitor, so the lack of diversity in the exchange of information. In order to change human-computer interaction interface, enables the computer to set the sound, text, graphics, image processing in one, the invention of the computer has multimedia capabilities of the best multimedia big screen, Wuhan projector device (Certified), multimedia large Jiuhua video screen provided by the Wuhan Engineering Limited. Video Jiuhua Wuhan Engineering Co., Ltd. (www.jowa-tech.com) is a leader in Wuhan, control and adjustment of the equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs . Jiuhua video in Wuhan leadership with the staff warmly welcome all inquiries negotiations to create video Jiuhua Wuhan better future.
