数据存储和GPS定位在冷藏机组控制器中的应用

Application of Data Storage and GPS Positioning in Refrigeration Unit Controller

本文研究了一种基于ATMEGA644PA-AU单片机的具有数据存储和GPS定位功能的冷藏机组控制器,其将冷藏运输车辆在运行过程中冷藏箱体内温度、冷藏制冷机组运行时各参数、GPS定位信息以逗号分隔文档的形式存储于USB闪存盘中,用以实现冷藏机组运行时的全过程参数的存储与查询,为冷藏机组的维修、运输货物的保存、品质的查询提供详实、可靠数据。

In this paper,a refrigeration unit controller with data storage and GPS positioning function based on ATMEGA644PA-AU single-chip microcomputer is studied.The parameters of the refrigerated transport vehicle during operation,the parameters of the refrigerating and cooling unit,and the GPS positioning information are stored in a USB flash drive as comma-separated document,in order to store and query the entire process parameters of the refrigeration unit during operation,providing detailed and reliable data for the maintenance of the refrigeration unit and the storage quality of the transported goods.
