设计一种由STC89C52单片机和nRF24L01无线模块等组成的自动报站系统。该系统主要由发射模块和接收模块两部分组成，接收模块通过接收无线模块发送的信号，再通过CPU发出指令，控制语音模块，从而达到自动识别、自动报站的功能。该系统解决了一对一的单信道信息发送接收模式，实现了一对多的多信道信息发送接收模式，在设计成本上有极大的优越性，提高了站台的利用率，减少空间的占用，实现了城市公交报站的智能化。
設計一種由STC89C52單片機和nRF24L01無線模塊等組成的自動報站繫統。該繫統主要由髮射模塊和接收模塊兩部分組成，接收模塊通過接收無線模塊髮送的信號，再通過CPU髮齣指令，控製語音模塊，從而達到自動識彆、自動報站的功能。該繫統解決瞭一對一的單信道信息髮送接收模式，實現瞭一對多的多信道信息髮送接收模式，在設計成本上有極大的優越性，提高瞭站檯的利用率，減少空間的佔用，實現瞭城市公交報站的智能化。

An automatically stops system composed of STC89C52 microcontroller, NRF24L01 wireless module, and other components is designed. The system is mainly composed with transmitting module and receiving module. The receiving module receives signals which are sent by the wireless module, then sends instructions by CPU to control voice module, and realizes the function of automatic identification and automatic stop announcing. The proposed system replaces one?to?one single channel infor?mation sending and receiving mode, while realizes one?to?many multi?channel information sending and receiving mode, also has great advantages in design cost, improves the utilization rate of the platform and reduces the occupied space, realizes the intelli?gence of city bus stops.
