【摘要】：隨著肺癌發(fā)病率和死亡率的提高,人們越來越重視肺癌的檢測。對肺癌的研究發(fā)現(xiàn),肺癌患者呼出的氣體中含有可用于檢測肺癌的物質(zhì)——肺癌標志物。本課題組提出了一種利用卟啉傳感器陣列檢測肺癌的新型檢測方法。隨著研究的不斷深入,需要經(jīng)常調(diào)整肺癌檢測儀器的軟件功能。如果使用常規(guī)的軟件開發(fā)方式,存在開發(fā)周期長,不易擴展等不足。本文旨在基于Qt插件技術(shù)設計和實現(xiàn)一套具有高擴展性和復用性的用于肺癌氣體檢測的嵌入式控制軟件系統(tǒng)。為了完成這個目標,本文的研究工作從以下幾個方面展開:(1)做出軟件的需求分析,并基于Qt插件技術(shù)完成系統(tǒng)的設計。通過系統(tǒng)設計,將本軟件總體上分兩部分。一部分運行在PIC16F877A型單片機構(gòu)成的下位機,一部分運行在Tiny6410嵌入式平臺構(gòu)成的上位機。在每個部分又將程序進行了模塊劃分。將下位機分為簡單IO口模塊,微型氣泵模塊,溫濕度采集模塊,串口通信模塊和“看門狗”模塊。將上位機分為簡單類插件和復雜類插件。(2)下位機程序中,分別實現(xiàn)了簡單IO口模塊,微型氣泵模塊,溫濕度采集模塊,串口通信模塊和 看門狗‖模塊的功能。(3)在上位機程序中,分別實現(xiàn)了簡單類插件、復雜類插件、GUI界面、主體程序的功能。主體程序中使用任務池的類,實現(xiàn)了在配置文件中指定器件動作的功能。并使用該方法,完成了富集循環(huán)任務,檢測循環(huán)任務和攝像頭的采集等任務。在GUI界面的設計中遵循統(tǒng)一的風格,設計出實用、美觀的登錄界面、執(zhí)行界面和結(jié)果顯示界面。(4)將宿主機中的軟件交叉編譯后移植到嵌入式設備中,并測試它的功能正確性、容錯性、可擴展性和可復用性。為了測試功能正確性,在室溫為25攝氏度,濕度為67%的環(huán)境下進行大量的實驗,結(jié)果軟件均能正常的運行。為檢測系統(tǒng)的容錯性,分別做了登錄驗證容錯性測試、溫度超閾值容錯性測試、串口通信容錯性測試,結(jié)果軟件在各種錯誤條件下均能提示出錯。為檢測軟件的復用性和可擴展性,以擴展一個直通電磁閥為例,復用直通電磁閥插件完成了程序的擴展。經(jīng)過以上的工作,本文基于Qt插件技術(shù)實現(xiàn)了肺癌氣體檢測控制軟件系統(tǒng)。該軟件系統(tǒng)實現(xiàn)了預期的功能,具有良好的擴展性、可復用性和容錯性。
[Abstract]:With the increasing incidence and mortality of lung cancer, more and more attention has been paid to the detection of lung cancer. Lung cancer studies have found that lung cancer markers are found in the gases exhaled by lung cancer patients. A new detection method for lung cancer using porphyrin sensor array was proposed. With the development of research, the software functions of lung cancer detection instruments need to be adjusted frequently. If the conventional software development mode, there are long development cycle, not easy to expand, and so on. The purpose of this paper is to design and implement an embedded control software system for lung cancer gas detection based on QT plug-in technology. In order to achieve this goal, the research work of this paper starts from the following several aspects: 1) makes the software requirement analysis, and completes the system design based on QT plug-in technology. Through the system design, the software is divided into two parts. One part runs in the lower computer composed of PIC16F877A single chip computer, and another part runs in the upper computer composed of Tiny6410 embedded platform. In each part, the program is divided into modules. The lower computer is divided into simple IO port module, micro air pump module, temperature and humidity acquisition module, serial communication module and "watchdog" module. The upper computer is divided into simple class plug-in and complex class plug-in. 2) in the lower computer program, the simple IO port module, the micro air pump module, the temperature and humidity collection module are implemented, respectively. The function of serial communication module and watchdog module. In the upper computer program, the functions of simple class plug-in, complex class plug-in and GUI interface and main program are realized respectively. The main program uses the class of task pool to realize the function of specifying device action in configuration file. By using this method, the tasks of enrichment cycle, detection of cycle and acquisition of camera are accomplished. Following the unified style in the design of GUI interface, designing a practical and beautiful login interface, executing interface and result display interface. 4) transplanting the software in host computer to embedded device after cross-compiling, and testing its function correctness. Fault tolerance, extensibility and reusability. In order to test the correctness of the function, a large number of experiments were carried out at room temperature of 25 鈩，
