【摘要】：為了解決高速轉(zhuǎn)動物體的溫度測量問題,設(shè)計了一種基于藍(lán)牙的多路無線測溫系統(tǒng)。該系統(tǒng)以熱電偶為信號來源,采用AD595和兩級放大電路進(jìn)行信號放大,以Silicon Labs公司研發(fā)的C8051F340單片機(jī)為控制核心,通過其內(nèi)部的ADC0子系統(tǒng)完成對溫度信號模擬量的采集。使用VC++6.0開發(fā)的上位機(jī)可以通過藍(lán)牙發(fā)送指令給C8051F340,使其執(zhí)行相應(yīng)的溫度采集動作,并將傳回的溫度值顯示出來。實(shí)驗(yàn)結(jié)果和在制動器測試機(jī)上的應(yīng)用表明,該無線測溫系統(tǒng)范圍在0~1 000℃,精度能達(dá)±0.3℃,而且系統(tǒng)穩(wěn)定性好,能很好地滿足各種工業(yè)溫度測量需要,特別是需要無線測溫的場合。
[Abstract]:In order to solve the temperature measurement problem of high speed rotating object, a wireless temperature measurement system based on Bluetooth is designed. The system uses thermocouple as the signal source. AD595 and two-stage amplifier circuit are used to amplify the signal. The control core is C8051F340 single-chip microcomputer developed by Silicon Labs Company. Through its internal ADC0 subsystem to complete the temperature signal analog acquisition. The host computer developed with VC 6.0 can send instructions to C8051F340 through Bluetooth. The result of the experiment and the application in the brake test machine show that the wireless temperature measuring system is in the range of 0 ~ 1 000 鈩，
