【摘要】：隨著國民經(jīng)濟(jì)的發(fā)展，人們對生活品質(zhì)的要求越來越高。制冷系統(tǒng)是提升人們生活品質(zhì)的重要設(shè)備之一，成為了人們家居必備產(chǎn)品。冰箱和冷柜提供的冷藏和冷凍方式，保證了食品新鮮，空調(diào)設(shè)備為居民提供了舒適的家居空氣環(huán)境。所以，對制冷系統(tǒng)的維修、維護(hù)顯得越發(fā)重要。保證制冷系統(tǒng)的良性運(yùn)行能夠有效地改善人居環(huán)境、節(jié)約能源、保護(hù)環(huán)境。 當(dāng)前對制冷系統(tǒng)進(jìn)行維保主要是傳統(tǒng)的機(jī)械式和查表法。本論文闡述了制冷系統(tǒng)監(jiān)測儀及其分析軟件的開發(fā)過程和測試結(jié)果，該系統(tǒng)克服了傳統(tǒng)方式的操作繁瑣、分析復(fù)雜、攜帶不便等缺點。具有一體化、便攜性、智能化等優(yōu)點，可有效地用于制冷系統(tǒng)的調(diào)試、安裝、檢修、維護(hù)等。 論文介紹了制冷系統(tǒng)國內(nèi)外研究現(xiàn)狀，在分析制冷原理、研究維修策略等基礎(chǔ)上，，提出了制冷系統(tǒng)監(jiān)測儀及其分析軟件的設(shè)計方案，詳細(xì)闡述了實現(xiàn)過程，分析了其中關(guān)鍵技術(shù)。經(jīng)過測試，系統(tǒng)功能完善、運(yùn)行穩(wěn)定。 制冷系統(tǒng)監(jiān)測儀用于對制冷系統(tǒng)各個參數(shù)的測量和分析。系統(tǒng)采用ARM Cortex-M3的低功耗微處理器STM32L151CB為核心，設(shè)計了顯示、采集、通信、控制等多個模塊的硬件系統(tǒng)，并編寫基于C語言的控制程序，使得各個模塊能夠協(xié)調(diào)統(tǒng)一地工作。并在此基礎(chǔ)上，分析了采集、標(biāo)定、功耗、抗干擾等方面的關(guān)鍵技術(shù)。 制冷系統(tǒng)分析軟件用于配合制冷系統(tǒng)監(jiān)測儀，進(jìn)行功能拓展、直觀顯示、深入分析等功能。軟件基于微軟公司的.NET平臺編寫，采用C#WinForm的編程方式，用SQL2005數(shù)據(jù)庫作為數(shù)據(jù)存儲。進(jìn)行了控制模塊、通信模塊、數(shù)據(jù)分析模塊、數(shù)據(jù)庫模塊、數(shù)據(jù)交互模塊的開發(fā)。并分析了數(shù)據(jù)加密、數(shù)據(jù)交互、壓焓圖等方面的關(guān)鍵技術(shù)。 最后對制冷系統(tǒng)監(jiān)測儀及其分析軟件分別進(jìn)行了測試。首先進(jìn)行了模塊測試，在各個模塊都正常工作的情況下再進(jìn)行集成測試。集成測試通過后，將系統(tǒng)放置于試驗臺，測試系統(tǒng)在真實制冷系統(tǒng)環(huán)境中的工作狀況。測試結(jié)果表明，系統(tǒng)功能完善、工作穩(wěn)定、抗干擾性強(qiáng)，可應(yīng)用于制冷系統(tǒng)中。
[Abstract]:With the development of national economy, people's demand for quality of life is higher and higher. Refrigeration system is one of the important equipments to improve people's quality of life. Refrigerators and refrigerators provide refrigerating and freezing methods to ensure fresh food, air conditioning equipment for the residents to provide a comfortable home air environment. Therefore, the maintenance and maintenance of refrigeration system becomes more and more important. Ensuring the benign operation of refrigeration system can effectively improve the living environment, save energy, and protect the environment. At present, the maintenance of refrigeration system is mainly based on the traditional mechanical and table checking method. This paper describes the development process and test results of the refrigeration system monitor and its analysis software. The system overcomes the shortcomings of the traditional operation, such as complicated operation, complex analysis, inconvenient carrying and so on. With the advantages of integration, portability, intelligence and so on, it can be effectively used in the commissioning, installation, overhaul and maintenance of refrigeration system. This paper introduces the current research situation of refrigeration system at home and abroad. Based on the analysis of refrigeration principle and maintenance strategy, the design scheme of refrigeration system monitor and its analysis software is put forward, and the realization process is described in detail. The key technologies are analyzed. After testing, the system function is perfect and the operation is stable. The refrigeration system monitor is used to measure and analyze the parameters of the refrigeration system. The system adopts ARM Cortex-M3 low power microprocessor STM32L151CB as the core, designs the hardware system of display, acquisition, communication, control and so on, and compiles the control program based on C language, which makes each module work harmoniously and uniformly. On this basis, the acquisition, calibration, power consumption, anti-interference and other key technologies are analyzed. The analysis software of refrigeration system is used to cooperate with the monitor of refrigeration system. The software is based on. Net platform of Microsoft Corporation. It uses C#WinForm programming method and SQL2005 database as data storage. Control module, communication module, data analysis module, database module, data interaction module are developed. The key techniques of data encryption, data interaction and enthalpy diagram are analyzed. Finally, the refrigeration system monitor and its analysis software are tested. First, the module test is carried out, and then the integration test is carried out under the condition that each module works normally. After the integrated test is passed, the system is placed on the test bench, and the working condition of the system in the real refrigeration system environment is tested. The test results show that the system has the advantages of perfect function, stable work, strong anti-interference, and can be used in refrigeration system.
