Real time monitoring of the tower liquid level changes, monitoring process intelligent, LCD display realtime display of liquid level, when the level exceeds the set value of the upper or lower buzzer alarm, LED lights flashing alarm.According to the main function of the remote monitoring system, the design scheme is presented and demonstrated. Design includes two parts of hardware design and software design. The hardware includes the smallest singlechip microputer, the matrix keyboard module, the wireless transceiver module, the display module and the alarm module of the five parts. Singlechip selection macro crystal STC STC89C52。 matrix keyboard input level simulating data value is passed to the wireless module, and data processing。 1602 LCD display tower liquid level information, and a parison with the input value。 lightemitting diode and the buzzer to alarm for abnormal situation. Software using modular design method, mainly divided into main program, wireless transmitting subprogram module, wireless receive subroutine, key detection subroutine, liquid crystal display subroutines, alarm module subroutine six parts. The system of hardware and software debugging, the simulation level of data through nrf24l01 module is transmitted to another nrf24l01 wireless module, through the microcontroller decoding display on the LCD display, when the numerical received more than 1000 or less than 10 ,the buzzer and the lightemitting will give an alarm.Key Words: Nrf24l01。MCU。 Remote transmission。 Display鹽城工學院本科生畢業(yè)設計說明書( 2022)目 錄1 概述 ..................................................................................................................................1 課題研究背景與意義 ...........................................................................................1 課題設計內容 .......................................................................................................12 方案設計選擇 ..................................................................................................................2 單片機選擇 ............................................................................................................2 無線裝置選擇 ........................................................................................................3 顯示模塊選擇 ........................................................................................................4 總體方案 ................................................................................................................43 硬件電路設計 ..................................................................................................................5 最小系統(tǒng)模塊 ........................................................................................................5 矩陣鍵盤電路設計 ................................................................................................6 無線收發(fā)電路設計 ................................................................................................7 nrf24l01 概述 ...............................................................................................8 引腳功能及描述 ..........................................................................................8 工作模式 ......................................................................................................9 工作原理 ....................................................................................................10 配置字 ........................................................................................................10 LCD 顯示模塊 .....................................................................................................114 軟件系統(tǒng)設計 ................................................................................................................13 總流程圖設計 ......................................................................................................13 矩陣鍵盤電路軟件設計 ......................................................................................14 無線發(fā)射模塊軟件設計 ......................................................................................15 無線接收模塊軟件設計 ......................................................................................16 LCD1602 顯示器軟件設計 .................................................................................17 蜂鳴器報警電路 ..................................................................................................185 系統(tǒng)的調試及實驗結果 ................................................................................................20 調試步驟 .............................................................................................................20 實驗結果 ..............................................................................................................20結 論 ...............................................
