"无线数据采集与显示系统设计及实现"

本系统是一个无线数据采集系统，使用两片单片机作为控制和处理核心，由数据采集和数据显示两个分系统组成。系统核心模块采用了两块NRF509无线收发模块来完成数据的无线传输。在数据采集系统中，通过五路DS18B20和五路DHT11进行数据采集，并使用红外遥控指定数据的发送，LED灯和1602液晶的显示使得数据传输更加直观。数据显示系统中采用了友好的中文显示和12864液晶显示屏，同时还集成了DS1302时钟、EEPROM数据存储和报警模块，通过操作键盘可以实现五路温度接收显示、五路湿度接收显示、数据实时保存和可查询，以及可设定数据报警范围并实时监测报警等功能。 关键字：单片机、NRF509无线收发、DS18B20、DHT11、12864液晶 Abstract: The system uses two single-chip microcontrollers as control and processing cores, with two subsystems for data acquisition and data display. The core module of the system uses two NRF509 wireless transceiver modules to complete wireless data transmission. In the data acquisition system, data is collected using five DS18B20 and five DHT11, and then the specified data is transmitted using infrared remote control, with LED lights and a 1602 LCD display for more intuitive presentation. The data display system features a user-friendly Chinese display and a 12864 LCD screen, along with a DS1302 clock, EEPROM data storage, and an alarm module. Data can be received and displayed for five temperature and humidity sensors, with real-time data saving and querying, as well as the ability to set data alarm ranges and monitor alarms in real time. Keywords: microcontroller, NRF509 wireless transceiver, DS18B20, DHT11, 12864 LCD.
