introduction In recent years, with the rapid development of the LED industry, the display models and specifications are very numerous, and the flowers are released, giving users more choices and making the LED display more colorful. However, too many models and specifications have brought some difficulties in engineering applications. Due to the large number of manufacturers and the lack of uniform standards, the installation and debugging of LED displays has become a very heavy task. In addition, installation and commissioning involves more than 20 parameters, which are very demanding and can only be completed by professional technicians. In fact, most of the installation and commissioning is repetitive work, which has caused many professional and technical personnel to be involved in the commissioning of various projects, resulting in great waste of manpower. Therefore, it has been suggested that it is possible to debug and form data files in advance. Professional technicians do not need to go to the site, and general engineers can download and complete the debugging on site, so LED intelligent configuration technology emerges as the times require. After market research, some LED control software also implements the function of intelligent configuration, but the effect is not ideal, such as too many steps, not intuitive, complicated and so on. Based on this, after research, this paper proposes a method of intelligent configuration, allowing users to make choices only through the "next step" way, at least seven steps can automatically complete the intelligent configuration, debugging is successful, generate data files for storage And download to use. 1. Analysis of main functional requirements and model construction Due to different manufacturers, the number of parameter items of the display screen is also different, but basically there are more than twenty items in each display screen. After analysis and classification, it can be divided into three types: core parameters, basic parameters and auxiliary parameters. (1) Core parameters The core parameters are the parameters necessary for the display. If the settings are not correct, the light is not displayed, and the screen is burned. The core parameters include cascading direction, OE polarity, data polarity, display type, color, scanning mode, walking order and line order. (2) Basic parameters The basic parameters are the basic parameters of the display. If the settings are not correct, they cannot communicate, display or display abnormally. The basic parameters include display width, display height, control card address, baud rate, IP address, port number, MAC address, subnet mask, gateway, display refresh rate, shift clock frequency, and line blanking time. 12 items.
