基于 RFID 的公交自动报站器摘 要系统是基于 RFID 的公交自动报站器，主要的核心器件是 STC89C52 单片机。工具包括显示控制、主控制器、语音播报控制、按键输入、IC 卡识别。在基于 RFID的公交自动报站器硬件设计中，选择单片机作为系统的核心控制原件，具体设计内容包含选取的基于 RFID 的公交自动报站器设计方案、单片机以及传感器的种类及型号，此外还需结合各部件进行显示模块的设计；在系统软件设计中，最核心的内容为系统程序的设计，程序运算结果可由显示模块加以呈现。系统有两种运行模式包括手动报站模式，自动报站模式，手动报站通过按键控制报站，自动模式在 IC 卡识别后进行报站。IC 卡识别选择 RC522。语音播报选择 WT588 模块。选取 C 语言实现代码开发，选取 Keil 工具实现代码开发运行。不断优化，完成设计。关键词：RFID；公交自动报站器；语音播报；RC522IAbstractThe system is an automatic bus stop announcer based on RFID. The main core device is STC89C52 single chip computer. Tools include display control, main controller, voice broadcast control, key input, IC card recognition. In the hardware design of bus automatic stop announcer based on RFID, single-chip computer is selected as the core control original of the system. The specific design includes the design scheme of bus automatic stop announcer based on RFID, the types and types of single-chip computer and sensors. In addition, the display module needs to be designed in combination with various components. In the software design of the system, the core content is the system process. The result of program operation can be presented by display module. There are two operation modes in the system, including manual mode and automatic mode. The manual mode controls the station by pressing keys. The automatic mode reports the station after the IC card recognition. IC card identification selection RC522. WT588 module is selected for voice broadcasting. Select C language t...
