【摘要】：在现代社会,科技迅猛发展,LED显示屏在众多行业被推广和应用。在国防行业,军队数据信息的显示、国防系统的展示,在公交、地铁、高铁站台等交通行业的数据显示,在矿产、工厂等实时监控领域的应用,囊括了大部分行业都有的LED点阵显示系统的身影。本论文的研究内容是,信号源如何通过相应的网传设备完整、即时的传输到相应的显示设备,具体的就是GSM网络短信的发送,通过短信来实时的监测控制改变LED显示屏的显示内容,成为一套比较独立的系统。使工作的速度得到大幅的提升,实现智能化的生活。本论文主要从以下四个方面来介绍描述本系统工作的主要步骤:1.实时更新LED输出信息,实现信息更新的实时性。2.将所有的字符建立对应的字符模的一一映射,输入LED点阵,传输到LED屏幕上。3.从PDU码中提取有用的信息对应到相应的字符。4.通过GSM网络获取资源。本论文所讨论的重点是如何通过GSM网络获取资源、从PDU码中提取有用的信息对应到相应的字符、实时更新LED输出信息。其中有三个难点:1.资源的获取2.通过PDU编码获取有用的资源3.通过点阵使字模在LED屏幕上显示本论文的开发环境是Linux,上位机是由32位ARM微处理器完成数据的传输,下位机则是LED显示屏作为其控制平台和硬件框架。
[Abstract]:In modern society, the rapid development of science and technology LED display screen in many industries have been promoted and applied. In the defense industry, the display of military data and information, the display of national defense systems, the display of data in transportation industries such as public transport, subway and high-speed rail stations, and the application of data in real-time monitoring fields such as minerals, factories, etc. Includes the majority of industries have a LED lattice display system shadow. The research content of this thesis is how to transmit the signal source to the corresponding display device through the corresponding network transmission equipment, specifically the sending of GSM network short message. Through short message to monitor and control real-time change the display content of LED display, become a set of relatively independent system. So that the pace of work has been greatly improved to achieve intelligent life. This paper mainly introduces the following four aspects to describe the main steps of the system work: 1. Update the output information of LED in real time, realize the real time. 2. 2. All the characters to establish the corresponding character module one mapping, input LED lattice, transfer to the LED screen. 3. Extract useful information from the PDU code corresponding to the corresponding character. 4. 4. Access to resources through the GSM network. This paper focuses on how to obtain resources through GSM network, extract useful information from PDU code to corresponding characters, and update LED output information in real time. There are three difficulties: one. Access to resources. Get useful resources through PDU coding. The development environment of this thesis is Linux. the upper computer is completed by 32-bit ARM microprocessor and the lower computer is LED display screen as its control platform and hardware frame.
