【摘要】 通过多个高精度温度传感器DS18B20,采集建筑物室内不同位置的温度,然后将采集到的数据通过一线总线技术传送给精简指令单片机AT90S8515,单片机对采集到的数据进行分析,转换成实际温度值后,并将转换后的数据通过RS232串行接口传递给上位PC机,上位PC机对AT90S8515单片机上传的数据再进行处理,从而分析建筑物是否达到节能标准.更多还原

【Abstract】 This system is based on the temperature sensor DS18B20 and the RISC microchip AT90S8515,the DS18B20 sensors get the temperature in the room,then convert them into digit signal,after that the AT90S8515 gets the converted data into the microchip memory by using one-wire bus,the computer can use RS232 series interface communicate with the AT90S8515 microchip.When the data of the microchip are in the computer,the computer can analysis them and know the building’s energy saving quality.更多还原
