Hot backup communication system and communication interface control module thereof

Abstract

The invention provides a hot backup communication system and a communication interface control module thereof. The communication interface control module is provided with a main / standby switching logic control unit and a selector switch, the main / standby switching logic control unit is connected with a main module and a standby module; the main / standby switching logic control unit is existent independent from the main module and the standby module, a switching instruction of the main module or the standby module can be acquired only through the main / standby switching logic control unit, which communication system module should be set as the working state and which communication system module should be set as the backup state can be obtained according to the switching instruction of the main module and the standby module; especially, when the communication between the main module and the standby module is abnormal, and the main module and the standby module monitors each other, the switching of the main module and the standby module can be realized through the respective monitoring of the main / standby switching logic control unit, the reliability of the switching between the main module and the standby module in the hot backup communication system is improved, and the communication suspension situation is reduced.

Description

technical field [0001] The invention relates to the technical field of data communication hot backup, in particular to a hot backup communication system and a communication interface control module thereof. Background technique [0002] In the communication network, the communication system provides technical support for wireless signal coverage in various places. [0003] During the communication process, the communication system equipment often has abnormal conditions such as power failure, network congestion, communication system equipment hang-up, chip abnormality, program runaway, etc. At this time, the communication in this area will not be guaranteed, and the equipment needs to be repaired, or Replace the failed equipment in the system with a new communication system equipment. Due to equipment failure, it will affect the quality of the mobile communication network in this area and cause unnecessary losses. Conventional communication system equipment lacks considera...

Problems solved by technology

Due to the failure of the equipment, it will affect the quality of the mobile communication network in the area and cause unnecessary losses

Conventional communication system equipment lacks consideration of system backup during system design, and with the requirements for network coverage stability in some scenarios, it is necessary to carry out hot backup for communication system equipment, power supply modules, digital modules, signal The processing module and power amplifier module are backed up, so it is necessary to carry out hot backup for the communication system equipment, such as backing up the power supply module, digital module, signal processing module and power amplifier module in the communication system equipment, so that when the system fails, it can Quickly switch to the backup system to ensure continuous coverage of the network

[0004] To solve the problem that the communication system equipment cannot provide the network by backing up the communication system equipment, the current solution is that the main module and the standby module monitor each other. When one module fails, notify the other module, and then Switch to another module, but if the two modules cannot communicate for some reason, the timely switching of the two modules cannot be realized, resulting in the suspension of communication
