摘要
为了防止汽车闯红灯,初步设计了一个智能小车自动识别十字路口红绿灯的系统。以STC89C52最小操作系统为控制核心、采用nRF24L01无线通讯等智能模块,实现车自动识别十字路口红绿灯功能。小车通过nRF24L01无线通讯识别直行方向是红灯还是绿灯,绿灯则通行、红灯则等待。主要给出了设计方案、无线通信模块的原理和2.4G通讯流程图。
In order to prevent the car ran a red light, a smart car＇ s system recognizing traffic lights automatically was prehiminary desiyned in this paper. It bases on the minimum operating system of STC89C52 for the controlling core, uses nRF24L01 wireless communications for intelligent modules, then to achieve identifying traffic lights automatically. It identifies whether the direction of the light is red or green by NRF24L01 wireless communication. If the light is green, the car will go straight. If the light is red, the ear will wait until the light turn green. The design scheme, principle of wireless communication module and 2.4 G communication flow chart was given in this paper.
