【摘要】：本文的目的是為長江航段水上設施拖載過載中的鋼絲繩受力狀況進行監(jiān)控而設計出一套監(jiān)控設備，系統(tǒng)由多個張力采集節(jié)點和一個接受節(jié)點組成，以一臺PC機為終端監(jiān)控設備，通過無線傳輸?shù)姆绞�，組成一個可實時采集各條鋼纜數(shù)據(jù)的無線通訊網絡。整個設計的工作模式為：整個無線網絡是一個星形的結構，各個節(jié)點的張力傳感器將鋼絲繩的受力數(shù)據(jù)進行采集，經AD轉換等處理后在單片機的控制下，以無線通訊的方式將數(shù)據(jù)發(fā)回給接收端點，接收端將信息接受后，通過USB接口傳遞到PC機上，利用Labview軟件設計的界面對數(shù)據(jù)進行實時的顯示及其他操作。本文從硬件、軟件以及網絡結構等三個方面分別進行了深入的研究。 硬件部分是按照模塊化的思想，分別對傳感器模塊、數(shù)據(jù)處理模塊、電源模塊、無線傳輸模塊、PC機模塊五個部分進行了設計。傳感器模塊主要涉及到傳感器類型及型號的選擇，AD轉換器的選取標準及選擇，本文采用的是北京中航科儀測控技術有限公司研制的CKY-126型張力傳感器以及美國AD公司出品的AD1674型AD轉換器。無線傳輸模塊式本文的重點，從芯片的性能、工作頻率、傳輸距離、編程難度、抗干擾能力、內部集成度等因素考慮，最終選擇的單片機是深圳宏晶公司生產的STC11F02E型微處理器以及挪威NORDIC VLSI公司推出的nRF905無線傳輸芯片，然后對系統(tǒng)的晶振電路、電源模塊、穩(wěn)壓電路進行了設計。上位機模塊主要的內容是接收端芯片與PC機連接方式的選擇，，在比較了USB接口方式和串口連接方式的優(yōu)劣后，選用了USB的連接方式，給出了USB芯片PL2303的電路圖和實物圖。 軟件部分主要同樣按照模塊化的思想，給出了各個模塊的程序流程圖及部分源程序、重點介紹了無線傳輸模塊nRF905無線芯片的初始化、寄存器配置以及如何通過SPI接口接受單片機的指令的工作原理。PC機模塊以Labview圖形化編程軟件為基礎設計了進行監(jiān)控的人機界面，包括主控界面、報警設置界面、歷史數(shù)據(jù)顯示界面和數(shù)據(jù)曲線顯示界面共四個界面。
[Abstract]:The purpose of this paper is to design a set of monitoring equipment for monitoring the stress condition of wire rope in the overloading of water facilities on the Yangtze River. The system consists of a number of tension acquisition nodes and a receiving node. With a PC as the terminal monitoring device, through wireless transmission. Constitute a wireless communication network which can collect the data of each cable in real time. The working mode of the whole design is as follows: the whole wireless network is a star structure. The tension sensor of each node collects the stress data of the wire rope and sends the data back to the receiving endpoint by wireless communication under the control of single chip microcomputer after AD conversion. After receiving the information, the receiver transmits the information to PC through USB interface, and uses the interface designed by Labview software to display the data and other operations in real time. The software and network structure are studied in detail. The hardware part is based on the idea of modularization, sensor module, data processing module, power module, wireless transmission module. The five parts of PC module are designed. The sensor module mainly involves the selection of sensor type and model and the selection standard and selection of AD converter. This paper uses the CKY-126 tension sensor developed by Beijing Aerospace instrument Measurement and Control Technology Co., Ltd. And the AD1674 type AD converter produced by AD Company of USA. The point. From the chip performance, working frequency, transmission distance, programming difficulty, anti-jamming ability, internal integration and other factors. The final choice of microcontroller is Shenzhen Hongjing company produced STC11F02E microprocessor and Norway's NORDIC VLSI nRF905 wireless transmission chip. Then the crystal oscillator circuit, power supply module, voltage stabilizer circuit are designed. The main content of the upper computer module is the choice of the connection mode between the receiving chip and PC. After comparing the advantages and disadvantages of USB interface mode and serial port connection mode, the connection mode of USB is selected, and the circuit diagram and physical diagram of USB chip PL2303 are given. In the software part, according to the idea of modularization, the program flow chart and part of the source program of each module are given, and the initialization of the wireless transmission module nRF905 wireless chip is emphasized. Register configuration and how to receive the instruction of MCU through SPI interface. PC module is designed based on Labview graphical programming software to monitor the man-machine interface. It includes four interfaces: main control interface, alarm setting interface, historical data display interface and data curve display interface.
