Problems solved by technology
When the host has communication links of multiple communication protocols, if the host detects that the communication link of a certain communication protocol fails, based on the dual-machine redundancy mechanism, the communication links of multiple communication protocols will be switched at the same time , the faulty communication link will be switched, and the normal communication link will also be switched. Due to the switching delay, the communication efficiency between the host and the communication device is reduced.

Embodiment Construction
[0058] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of them. Based on the embodiments of the present application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present application.
[0059] The communication method based on dual-machine redundancy provided by the embodiment of the present invention can be applied in figure 1 In the communication management system shown, the system may include a first terminal and a second terminal. The communication management system may be a gateway system, so the first terminal and the second terminal are respectively the first gateway and the second gateway.
[0060] In order to ensure the accu...

The application discloses a communication method and device based on dual-machine redundancy. In this method, the main protocol module in the first terminal sends the first request message including the device identification to the communication device; within the receiving time period set by the communication protocol, if it is detected that there is a communication device that has not sent the first response message The communication device sends a second request message including the device identification of the communication device that has not sent the first response message to the backup protocol module in the second terminal according to the preset dual-machine redundancy configuration information, so that the backup protocol The module sends a second request message to the communication device that has not sent the first response message, and receives the second response message sent by the communication device that has not sent the first response message according to the second request message. The method improves the anti-risk capability and communication efficiency.
Description
technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method and device based on dual-device redundancy. Background technique [0002] Dual-machine redundancy means that two devices will be installed as mutual backups, and only one device will collect data at the same time. Under normal circumstances, the device that performs tasks is called the host. When the communication link of the running host fails, the communication link of the host is switched to the communication link of the standby machine to continue to perform corresponding tasks, such as data collection, access and other tasks. The standby machine then feeds back the corresponding execution results to the main machine to restore the normal operation of the entire system. [0003] However, the inventors found that the above-mentioned dual-machine redundancy means that the host switches over the communication link after determining tha...
