Dual-redundancy communication device and method

Abstract

The embodiment of the invention discloses dual-redundancy communication a dual-redundancy communication device which comprises a functional board card which at least has one of the functions of data collection, data processing, data exchange and data storage; a controller performing data interaction with the functional board card and used for at least partially managing and controlling the dual-redundancy communication device; a bus set providing at least part of communication links for data interaction between the function board card and the controller and between the function board cards. The bus set comprises a first bus set, which is connected with the function board card and the controller to achieve at least part of data interaction between the function board card and the controllerand comprises an input data bus used for transmitting data from the function board card to the controller, and a second bus set which is used for redundant backup of the first bus set and shares a setof input data bus with the first bus set. The invention is used for solving the problem of unsmooth data transmission.

Description

technical field [0001] The invention relates to the field of communication equipment, in particular to a dual redundant communication equipment and method. Background technique [0002] At present, the technology of communication equipment is developing rapidly, and the efficiency and stability of data processing have become one of the directions of technical development in this field. When the amount of data processed by the communication device is large or the amount of data processing fluctuates greatly, it is inevitable that the data transmission on the bus is not smooth. Moreover, with the improvement of the integration level of communication equipment, the problem of unsmooth data transmission on the bus becomes more serious. [0003] Furthermore, there are many usage scenarios of communication equipment, especially in the case of harsh conditions such as high-speed transportation, it is inevitable that the main control board will work abnormally due to factors such a...

Problems solved by technology

When the amount of data processed by the communication device is large or the amount of data processing fluctuates greatly, it is inevitable that the data transmission on the bus will not be smooth.

Moreover, with the improvement of the integration of communication equipment, the problem of unsmooth data transmission on the bus is more serious

[0003] Furthermore, there are many usage scenarios of communication equipment, especially in the case of harsh conditions such as high-speed transportation, it is inevitable that the main control board will work abnormally due to factors such as the equipment usage environment is too bumpy or the ambient temperature, making the communication equipment function unable to function properly

[0004] Furthermore, the design of redundant backup for the components of communication equipment further causes data fluctuations in the process of switching between redundant components, and even the hidden danger of data loss, which will cause equipment paralysis

[0005] Therefore, how to ensure the data transmission capacity of the bus, how to ensure the working capacity of the main control board, and further avoid the phenomenon of unsmooth data transmission during the switching process between redundant components has become an urgent problem to be solved
