Cascade system capable of realizing automatic line bridging and method

Abstract

The invention discloses a cascade system capable of realizing automatic line bridging and a method. The cascade system comprises a central controller and a plurality of cascaded functional subunits, wherein each functional subunit comprises a micro-control module which is used for transmitting bridging control information when the result of the heartbeat detection of the environment monitoring board of the functional subunit of the level is abnormal; a drive module which is used for generating a bridging drive signal according to the received bridging control information transmitted by the micro-control module; and a line switching module which is used for bridging the functional subunit of the lower level with the functional subunit of the upper level or the central controller through a transmission line according to the bridging control signal transmitted by the drive module to realize the automatic bridging of the line. In the invention, through using the line switching module to bridge the functional subunit of the lower level with the central controller or the functional subunit of the upper level when the functional subunit of the level is failed, the range affected by the failure is reduced and the operation reliability of the system is improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a cascade system and method capable of realizing automatic line bridging. Background technique [0002] At present, many systems use a daisy chain cascading method to form a network in order to save the wiring cost of the line, such as figure 1 As shown, the functional subunit 3 is connected to the functional subunit 2 through the transmission line, the functional subunit 2 is connected to the functional subunit 1 through the transmission line, and the functional subunit 1 is connected to the central controller through the transmission line. [0003] However, the above-mentioned networking method has the following defects: when the functional subunit 2 fails, the functional subunit 3 cannot work normally, especially if the functional subunit 1 fails, a large area will be paralyzed, affecting the system normal work. Contents of the invention [0004] The purpose o...
