"无线数据传输系统设计与实现--毕业设计摘要"

本文介绍了一种无线数据传输系统的设计与实现方法，主要包括了无线数据传输系统的组成、AT89C51单片机串行口的工作方式以及其与无线数字电台接口的软硬件设计与实现方法。一般的数字采集系统通过传感器将捕捉的现场信号转换为电信号，经模/数转换器ADC采样、量化、编码后，形成数字信号，存入数据存储器，或送给微处理器，或通过无线方式将数据发送给接收端进行处理。无线数据传输系统是一种利用无线手段，将采集的数据由测量站发送到主控站的设备。关键字：无线数据传输，AT89C51单片机，模/数转换器，ADC采样，采集，信号。Abstract: This paper introduces a design and implementation method for a wireless data transmission system, including the components of the wireless data transmission system, the working mode of the AT89C51 single-chip microcontroller serial port, and the hardware and software design and implementation method of its interface with the wireless digital radio. In general, the digital acquisition system converts captured field signals into electrical signals through sensors, and after ADC sampling, quantization, and coding, it forms digital signals, which are stored in the data storage, sent to the microprocessor, or transmitted wirelessly to the receiving end for processing. The wireless data transmission system is a device that uses wireless means to transmit collected data from the measurement station to the main control station. Keywords: wireless data transmission, AT89C51 single-chip microcontroller, analog-to-digital converter, ADC sampling, acquisition, signal.
