摘要
系统以W77LE58单片机作为控制器核心,采用单总线温度传感器DS18B20进行多点温度检测,64Mb串行闪存M25P64进行数据存储,并配以键盘和显示电路,地温数据导出可以选择使用无线传输方式或USB接口传输方式。系统具有快捷、精度高、低功耗、存储容量大、抗干扰能力强等优点,实际使用中取得了良好的效果。
The W77LE58 MPU was taken as the controller core of system, 1-wire bus temperature sensor DS18B20 was carried on the multipoint temperature measurement devices, 64Mb serial flash memory M25P64 was used to save the measuring data, and the keyboard and the display circuit were also used in the system. The earth temperature data exporting could choose one of wireless transmission mode and USB transmission mode. Because of the merits of the high precision, the low power consumption, the large storage capacity and the strong antijamming ability, the system had obtained the good effect in the practical application.
