远程数据自动录取系统数据采集终端设计

为实现对远程数据的自动录取设计数据采集终端。终端由数据采集子系统、数据预处理子系统和后备电源子系统构成，实现对现场数据的实时采集、处理、存储及保护。后备电源子系统中的电网供电模块为终端提供所需各种电源，当电网供电监测模块检测到电源电压的异常时，后备电源供电模块为系统进行应急供电，并控制数据预处理子系统将采集数据存储、保护到冗余存储电路

The Design of the Data Acquiring Terminal on the Long-range Data Automatic Recording System

For realizing the data long range acquiring,the data acquiring terminal is designed.The terminal is made up of a data acquiring sub system,a data pre processing sub system and a back up power sub system.It is used to realize the scene data acquiring,processing,storing and protecting at the same time.The electrified wire netting supplying module in the back up power sub system provides power sources.When an unusual state is detected by the power detecting module,the module of back up power provides an emergency power for the system,and then the data acquired are stored and protected in the memory circuit.
