Cascade system capable of realizing automatic line bridging and method

Abstract

The invention provides a cascade system and method for realizing an automatic circuit bridge connection. The cascade system comprises a central controller and multiple cascaded functional sub-units, wherein each functional sub-unit comprises: a micro-control module, for transmitting bridge control information to a drive module, when the heartbeat detection result of the environment monitoring plate of the current level functional sub-unit is abnormal, after the cascade system powers on; a drive module, for generating a bridge drive signal according to the received bridge connection control information transmitted by the micro-control module; a circuit switching module, for bridge-connecting, according to the bridge connection control signal transmitted by the drive module, the functional sub-unit of the lower level to the functional sub-unit of the upper level or the central controller via a transmission wire, which realizes the automatic bridge connection of the circuit. In the present invention, by using the circuit switching module to bridge-connect the functional sub-unit of the lower level to the central controller or the functional sub-unit of the upper level when the functional sub-unit of the current level has a fault, the effect range of the fault 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...
