摘要
溫度監控在醫學工程、機械電機產業、綠能產業、工廠鍋爐及農漁民養殖業，皆可看到它的應用，但昂貴的資料擷取卡、無線傳輸設備及監控系統，使得此系統不易建置。在本研究中，我們將研製一套無線溫度即時監控系統，本系統皆採用簡單自製的軟硬體來實現此系統，本系統係由溫度感測元件AD590、ADC0804類比轉數位晶片電路、8051單晶片微處理器電路、RF無線收發模組、PC-based 個人電腦及人機操控界面組合而成，不僅價格便宜且容易實現，量測誤差小。系統由溫度感測電路來擷取類比溫度訊號，由A/D轉換電路轉換為數位訊號傳送至單晶片微處理器電路取樣、分析、儲存再透過串列埠RS232介面傳送訊號至RF無線模組，再由RF無線模組發射給遠端的RF無線模組接收，再經由RF無線模組經RS232介面傳送資料給人機電腦接收、儲存、研判，在回傳判斷後的控制信號給遙控端的資料擷取模組，將結果以燈號顯示，並作出控制動作達到即時監控的目的，若程式完全自動化後，更可進一步達到無人化高安全性的溫度監控功能。而未來運用此系統可有效掌握遠端機台的溫度、濕度、電壓、電流、壓力等多種重要類比訊號，並達到人員安全的保障及節省大量人力資源的耗費，測試結果顯示本系統可即時顯示溫度狀況並回傳信號，成功執行遠端警示顯示及安全。

Temperature monitoring in medical engineering, electrical machinery industry, green energy industry, factory boilers and aquaculture farmers and fishermen, can see its application, but expensive data acquisition card, wireless transmission equipment and monitoring systems, making the system easy to establishment . In the present study, we will develop a set of real-time wireless temperature monitoring system, the system's hardware and software are made using a simple to implement this system, the system line by the temperature sensing element AD590, ADC0804 analog switch digital chip circuit, 8051 single chip microprocessor circuits, RF wireless transceiver module, a combination of PC and PC-based man-machine control interface is made not only cheap and easy to implement, nor large measurement error. System consists of temperature sensing circuit to capture analog temperature signal, the A / D converter circuit to convert to digital transmission of signals to a single-chip microprocessor circuit sampling, analysis, storage and then transmitted through the serial port RS232 interface signals to RF wireless module then transmitted by RF wireless module to the far-RF wireless module receives, and then transfer the information received by the RS232 interface gives local computer via RF wireless module, storage, analyzing, after the return control signal to the remote end of the judgment data acquisition module, the results in light display and control action to achieve the purpose of real-time monitoring, the latter if the program is fully automated, it can further achieve unmanned high security temperature monitoring function. Using this system can effectively control the temperature of the distal end of the machine, humidity, voltage, current, pressure, and other important analog signal, and achieve security and safety of personnel save a lot of human resources, cost, test results show that the system can immediately display the temperature status and the return signal, the successful implementation of the distal end of the warning display and security.
