1、 智能远程控制 LED 显示设备设计 设计总说明 随着社会不断发展， LED 在当今社会生活中的应用已经越来越多， 越来越普 及。它的高效、环保、节能、低成本等优点使它倍受青睐，在显示领域受到了 广泛应用。然而目前采用有线方式传输、显示数据的 LED 点阵屏幕安装不便， 移动性较差，另外，LED 点阵屏尺寸多为整块固定的，安装时不能根据需要进行 调整。针对以上不足，本课题研制了一种采用智能远程控制的新型 LED 点阵屏 系统，系统通过无线方式进行通讯控制，同时，采用模块化 LED 显示屏设计， 使得屏幕尺寸大小可以根据实际需要来拼装，提高其实用性，避免了上述 LED 显示设备的缺点。 首先需要

2、进行总体方案设计，由设计需求确定系统结构，由此再得到硬件 选型。然后分模块设计具体系统电路，设计上位机、下位机端的软件程序，最 终制作实验室原型进行测试。本系统硬件部分单片机选择 STC89C52RC，无线数 据传输模块采用WSN-1101无线透传模块， LED显示模块采用74HC595和74HC164 进行控制，电源使用 7V 蓄电池转 5V 供电。经最终调试，系统稳定可靠，基本 达到设计要求。 关键词：单片机；点阵 LED；无线控制 Design of Intelligent Wireless Control LED Display Equipment Design Description

3、 With the continuous development of the society, the application of LED in the social life has become more and more popular Its high efficiency, environmental protection, energy saving, low cost and so on the advantages make it popular, in the display field has been widely used. However, the wired t

4、ransmission, display data led dot matrix screen to install the inconvenience, poor mobility. In addition, LED dot matrix screen size for block fixed, the installation can not according to need to adjust. To solve the above problem, this topic developed a using intelligent remote control model of LED

5、 lattice screen system, system by wireless communication control. At the same time, using modular design of LED display screen, makes the screen size can assembled according to the actual need, to improve the practicability and avoid the shortcoming of the LED display device. At first, we need to ca

6、rry out the overall plan design, the system structure is determined by the design requirements, and then the hardware selection.Then the sub module design of the specific system circuit, the design of the upper computer, the lower end of the software program, the final production of laboratory tests.The hardware part of the system is microcontroller STC89C52RC and wireless data transmission module, the wireless WSN-1101 for transparent transmission module, LED display module using 74HC595 and 7
