GPRS远程测控终端死机自动复苏电路的设计与实现

Design and Implementation of Automatic Recovery Circuit for GPRS Remote Measuring and Controlling Terminal Crash

GPRS网络的发展,使得GPRS远程终端迅速应用于各个领域。不过,在气象站使用GPRS的远程终端数据采集系统中发现,终端时常出现死机现象,常常需要派人去监控点进行人工断电复位,因此需要本文研制的GPRS的远程终端死机自动复苏电路来解决问题。

The development of GPRS network leads to the GPRS remote terminal being quickly applied to various fields. However it is found that the GPRS remote terminal data acquisition system used in weather stations often occur crash, therefore it is necessary to send staffs to recovery the power manually. In this article, an automatic crash recovery circuit for GPRS remote terminal is developed to solve the above problem.
