為提高溫度測量效率，降低系統(tǒng)的成本，擴(kuò)展傳輸距離，設(shè)計(jì)出一種新型溫度采集系統(tǒng)。單片機(jī)通過控制具有單總線方式的溫度傳感器DS18B20實(shí)現(xiàn)對溫度的測量，同時單片機(jī)通過控制具有單總線方式300～450MHz頻率范圍內(nèi)的MAX7044與MAX7033無線發(fā)射與接收芯片實(shí)現(xiàn)溫度數(shù)據(jù)的無線傳輸。與傳統(tǒng)溫度采集系統(tǒng)相比，該系統(tǒng)利用單總線方式連接，采用無線傳輸方式實(shí)現(xiàn)遠(yuǎn)距離通信，易于系統(tǒng)的集成與擴(kuò)展。實(shí)驗(yàn)結(jié)果表明，該系統(tǒng)結(jié)構(gòu)簡單、方便移植，能夠同時實(shí)現(xiàn)多達(dá)上百點(diǎn)溫度的測量與500m范圍的傳輸。 Abstract: To improve the temperature measurement efficiency and reduce system cost,expansion of transmission distance,a new type of temperature acquisition system is designed.Microcontroller controlled temperature sensor DS18B20which has a single-bus achieves temperature measurement,while microcontroller by controlled the MAX7044and MAX7033chip with a single-bus and having300~450MHz radiofrequency to achieve the wireless transmission of temperature data.Compared with conventional temperature acquisition system,the system uses single-bus connected,and uses wireless transmission means to achieve long-distance communications,easy-to-system integration and expansion.The experimental results show that the system is simple,convenient transplantation,and can be implemented in as many as a hundred-point temperature measure-ment and the transmission range of500meters.
