【摘要】：針對(duì)分布式光纖拉曼測(cè)溫系統(tǒng)中定標(biāo)光纖和雪崩光電二極管(APD)的溫控要求,設(shè)計(jì)了一套基于STM32的高精度恒溫控制系統(tǒng)。系統(tǒng)采用上下位機(jī)結(jié)構(gòu),上位機(jī)負(fù)責(zé)設(shè)定溫度值和顯示溫度數(shù)據(jù),下位機(jī)根據(jù)上位機(jī)的設(shè)定值利用PID算法對(duì)恒溫箱的溫度進(jìn)行控制。實(shí)驗(yàn)結(jié)果表明:在22℃的室溫下,定標(biāo)光纖溫度穩(wěn)定在(10±0.1)℃,APD溫度穩(wěn)定在(5±0.005)℃,上位機(jī)可準(zhǔn)確反映溫度的數(shù)值和變化趨勢(shì)。整套恒溫系統(tǒng)能夠滿足分布式光纖拉曼測(cè)溫系統(tǒng)的溫控要求。
[Abstract]:The temperature control requirements of calibrated fiber and avalanche photodiode (APD) in distributed fiber Raman temperature measurement system are discussed. A high precision constant temperature control system based on STM32 is designed. The system adopts the structure of upper and lower computer, and the upper computer is responsible for setting temperature value and displaying temperature data. The PID algorithm is used to control the temperature of the thermostat box according to the set value of the host computer. The experimental results show that the temperature of the calibrated fiber is stable at 10 鹵0.1 鈩，
