Problems solved by technology

[0005] 1. The existing gateway has low reliability
Once the gateway fails, the seamless switching of the gateway function cannot be realized, which will inevitably cause data loss and bring unpredictable operational risks to civil aviation, railway and other transportation systems
[0006] 2. The existing gateway cannot permanently retain the forwarded data
They support the easy-to-use Modbus protocol, but the Modbus protocol can only support short-distance transmission, and the implementation methods of the Modbus protocol by equipment manufacturers are not completely the same

Abstract

The invention discloses a gateway, and a gateway hot backup system and method. The gateway comprises a processor, a gateway interface and a storage. The processor comprises an input module, a configuration module, an analyzing module, a storage module and a forwarding module. The gateway hot backup system comprises at least two gateways which include a primary gateway and a secondary gateway. The primary gateway is connected with the secondary gateway. The primary gateway and the secondary gateway are connected to a joint lower computer and a joint upper computer. The primary gateway forwards acquired data packets and backs up data packets on the second gateway. The secondary gateway replaces the primary gateway when the primary gateway cannot operate normally. The gateway and the gateway hot backup system have the advantages that fast switching during gateway faults can be achieved, and integrity of forwarded data can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a gateway, a gateway hot backup system and a method thereof. Background technique [0002] Gateway, also known as network connector and protocol converter, is a facility used to provide network compatibility functions such as protocol conversion, routing selection, and data exchange when intercommunicating between networks using different architectures or protocols. In the fields of process automation, medicine, processing and manufacturing, transportation, national defense, aerospace, agriculture and buildings, gateways play an important role. [0003] Taking the field of transportation as an example, in industrial systems such as railways and aviation, a large amount of data is generated all the time, and these data need to be transmitted on networks of different protocols and network segments. Each piece of data is very important to the assessment and diagnosis of indu...
