System and method for automatically switching device identities to provide wireless communication

Abstract

The invention discloses a system and a method for automatically switching the identity of devices to provide wireless communication. After multiple working devices connected with the same wired network exchange the time of connection with the same wireless network, the identity of the devices is decided automatically. The working device becoming a main device can transmit survival information to the working devices becoming backup devices. When the backup devices cannot receive the survival information transmitted by the main device or the backup devices receive a switching notice transmitted by the main device, that the main device can no longer function properly is judged, and a new main device is automatically decided again. The stability of wireless communication on moving vehicles is improved. When there is no main device in a wireless network environment, the working devices can decide a new main device automatically and quickly.

Description

technical field [0001] The present invention relates to a mobile wireless communication system and method, in particular to a system and method for automatically switching device identities to provide wireless communication. Background technique [0002] A wireless network is a computer network that uses any one or more types of radio. The biggest difference from a wired network is that each node (node) in a wireless network can be connected to each other without cables. [0003] When there is a need for communication when wired networks cannot be used, wireless networks are often used for communication. For example, wireless networks can be used to communicate with trains, cable cars, and ships around railway stations, cable car tracks, docks, or canals. Time. However, since vehicles such as trains, cable cars, and ships will continue to move during wireless communication, the connection between the working device on the vehicle and the wireless access point is not stable...

AI Technical Summary

Problems solved by technology

However, since vehicles such as trains, cable cars, and ships will continue to move during wireless communication, the connection between the working device on the vehicle and the wireless access point is not stable, and may be affected by the environment from time to time. to interrupt

[0004] In order to solve the above problems, some vehicles currently have more than one working device. When the working device originally connected to the wireless access point cannot be connected to the wireless access point, other working devices installed on the vehicle will Try to connect with the wireless access point to maintain the stability of the wireless network through redundancy. The interval between the successful connection of the access point is often more than a few seconds. Such a time cannot be ignored in the use environment of the wireless network, and the data transmission process of the terminal device in the wireless network is often interrupted.

[0005] To sum up, it can be known that the prior art has long existed the problem of unstable wireless communication on mobile vehicles, so it is necessary to propose improved technical means to solve this problem
