闡述了一個(gè)由上位PC機(jī)和AT89C52下位單片機(jī)組成的主從分布式溫度巡回檢測(cè)系統(tǒng)。主從機(jī)采用RS-485 串行通訊標(biāo)準(zhǔn)進(jìn)行通信,可在下位單片機(jī)實(shí)現(xiàn)基本的溫度數(shù)據(jù)巡回檢測(cè)基礎(chǔ)上,由上位PC機(jī)實(shí)現(xiàn)綜合處理功能或擴(kuò)展為遠(yuǎn)程操作。整個(gè)系統(tǒng)具有巡檢速度快,擴(kuò)展性好的特點(diǎn)。
Abstract:
In this paper,a top PC and AT89C52 under-bit microcontrollers from the main component of the tour distributed temperature detection system is presented. Master and slave can use RS-485 serial communication standards for communications.Based on next-bit machine for basic goods temperature detected data Tour, the top can achieve the integrated treatment of PC functions or for the expansion of long-distance operation. The entire inspection system is fast, expansion.
