摘 要
 隨著光電技術的發展，紅外線已經被人們運用到各行各業。傳統測溫儀--如熱電偶測溫，雖然測量溫度范圍廣、上限值高，但是必須是接觸式的。這就造成了許多不便，而且造價高、精度小，使用率很低，已經被逐漸淘汰。而現代測溫技術采用非接觸式方式，對于距離造成的問題，采用溫度補償，加大了靈活性。由于其非接觸，不僅大大延長了使用壽命，而且提高了精度。
 由于紅外測溫涉及到光學和復雜補償電路等知識以及高額的費用，我不能完成，而是采用另一種方法。
 主控制器則選用8位AVR型單片機，溫度傳感器為高精度AD590，通過16位A/D MAX1415 數模轉換得到數字量供單片機分析處理；然后單片機通過程序軟件運行計算后講溫度值通過12864液晶顯示，并在ISD1720語音芯片進行語音播報，同時將分析的數值通過紅外發射模塊發送出去，從而進行遠距離監控。該儀器能夠達到0.1攝氏度以內的測量精度，該系統同時設有可矩陣式鍵盤輸入功能，通過紅外遙控改變報警上線和下線值模塊，語音播報更具人性化，液晶界面友好，擁有擴展功能，是理想的溫度監控報警的方案設計。

關鍵詞：溫度；無線；紅外；AVR；報警 

Abstract
 With the development of photovoltaic technology, infrared has been applied to all walks of life. Traditional thermometer--such as thermocouple, although measurement temperature range, upper value is high, but must be a contact. It creates a lot of inconvenience and the cost is high, Precision is the low，Usage is not frequent, which has been eliminated. Modern temperature adopted a non-contact in the way technology, for the problems caused by distance, using temperature compensation, improved flexibility. Because of its non-contact, not only prolong service life but also improves accuracy.
 As the optical and infrared temperature measurement involves the knowledge of complex compensation circuits, and high costs, I can not be completed, instead of using another method.
 The temperature monitoring system-based single-chip 8-bit AVR-based controller for a high-precision temperature sensor AD590, AD MAX1415 through the 16-bit digital conversion to be for single-chip analysis; and then single-chip analysis by software After calculating the temperature stresses through 12864 LCD, ISD1720 voice chip through the broadcast, at the same time, the analysis of numerical sent through the RF module to facilitate remote monitoring and control people. The system can accurately measure the temperature of 0.1 degrees Celsius, the system can be adopted at the same time with infrared remote control and set the alarm off the value of on-line modules, voice broadcast more humane, user-friendly LCD, but also the expansion of functions, is an ideal Monitor the temperature of the design.
