Research And Practice Of Large Scale Semiconductor Full-Color Illuminating Control System

On the model of concentrate management and distributed control, the article, which combined with the application of Semiconductor Illuminating in the special domain of landscape ornament, not only analyze and study how to establish a system of semiconductor full-color ornament lighting but also put forward a theory model and a real example in project. With the analyse of two traditional control model, the author put forward the system model of delamination management firstly, and then demonstrate the feasibility of realizing the full-color change with semiconductor based on the theory of LED and mixture color of light. In writing this article, the author try to give some useful suggestion on how to construct a whole software system and illustrate detailly how to establish a model for LED with adopting the technique of Object Oriented. Beyond what has been stated above, there is another important thing must to be mentioned: some new method was used in this application.Such as, it separate the data code explaim, LED control and data transmit into different model in order to parallel process. Furthermore, consider the double-buffer technique used in deal with move picture, it put forward a double-buffer mechanism that devide the communication area and the play area into two different logical parts in order to make full use of the limited resource of storage; and adopt the multi-purpose of the bus to extend the I/O capable of processor; and use the many of output PWM ,which was produced by timer used in firmware, to control the brightness of LED. At last, the author take the code explain model and the LED fulcolor control model as an example, illustrate its data structure and programme flow chart in detail, and give the implement of this system. In a word, the whole project is worthy to be apply and become widespread.
