带GPRS短信功能的双CPU小电流接地选线装置

Dual CPU Non-Solid Earthed Line Selection Device with GPRS Short Message Function

为了提高小电流接地系统的供电可靠性,提出了一种双CPU结构并带有GPRS短信功能的选线装置。采用单片机与DSP构成双CPU结构能充分利用单片机的硬件资源和DSP强大的数据处理能力,完全可以满足小电流接地保护装置的数据采集和各种保护算法的要求;采用GPRS短信技术可以实现远程报警和数据传输。本装置适用于配电系统,能达到较好的选线效果。

In order to raise power reliability for non-solid earthed system, a kind of dual CPU structured non-solid earthed system device with GPRS short message function was raised. Microcontroller and DSP constituted dual CPU structure which made full use of the hardware resources of microcontroller and data processing ability of DSE The system completely met requirements of non-solid earthed system protection device and various protection algorithms. Adopting GPRS technology can realize remote alarm and data transmission. This device is applicable for power distribution system, being able to get better line selection effect.
