Strategy of Reliable Connection for People Aerial Defence Alarm Central-controlled System
Chen Yong-sheng · Jisuanji gongcheng · 2007
The control-net for people aerial defence alarm system is an important subsystem and frail part,because the failure of it may directly lead to the failure of all the system.This paper proposes a communicate mechanism at the base of individual control-net,in order to improve the reliability for the connection between control-center and alarm end.Then the redundancy technique is introduced to our work based on the implement of control-net between control-center and alarm end through GPRS and PSTN.At the last part of the paper,the two control-nets are integrated seamlessly,when one control-net fails,the data would transmit through another one transparently,so the possibility of the failure of communication is decreased.
