基于Cortex的公路可变情报板可靠性设计
Reliability Design for Highway LED Displayer Based on Cortex Processor
【摘要】 针对现有户外高速公路LED可变情报板系统复杂、可靠性、维护性差等缺点,提出了基于STM32Cortex-M3处理器的分布式显示架构。在仍使用传统公路显示屏体的前提下,对控制系统进行改造,提高了屏的可靠性与可维护性,延长了屏的寿命。
【Abstract】 Aim at the shortcomings of complex system,poor reliability,poor maintenance for highway electronic displayer,a distributed display architecture based on STM32Cortex-M3 processor is proposed.On the premise of using the traditional displayer,the control system is modified.Reliability and maintainability of the screen are improved,and the life of the screem is prolonged.
