摘要
针对目前国内外温度检测仪器存在的问题,采用无线通讯技术和单片机技术,研制了便携式智能温度自动记录仪,该仪器实现了温度信号的无线传输,可以同时对多个通道的信号进行采集和处理,并智能判断温度变化是否异常并进行预警,具备温度记录查询、在温度超过设定值时报警、掉电自动保存数据、大容量存储、打印,与PC机进行通讯等功能,同时具有价格低、体积小、功耗小等优点。详细叙述了该仪器的软硬件组成和实现原理。
Based on the disadvantages of present temperature measuring instruments of home and abroad,has designed and developed a portable,intelligent and wireless instrument by employing the technology of wireless communication and single-chip microcomputer.Temperature signals can be transmitted wirelessly.This instrument can collect and process signals of multi channels.It can identify the abnormal temperature fluctuation and pre-alarm.It can record and search temperature,alarm when temperature exceeds the set value,print the temperature of certain period and communicate with personal computer and lodge much data and store them automatically when power is off.In addition,it is cheap,small and consumes less power.Introduced its constitution of hardware,software and theory in detail.
