Bidirectional wireless communication method, device and terminal

Abstract

The present invention provides a bidirectional wireless communication method, a device and a terminal, and relates to the technical field of communication. The invention is applied to a system including a host and a plurality of slave computers. The host and the plurality of slave computers are configured to sequentially and cyclically send out heartbeat packets at the interval of a fixed period of time. The method comprises the steps of receiving a host heartbeat packet sent from the host and a first slave computer heartbeat packet sent from a first slave computer by a second slave computer, wherein the host heartbeat packet contains the information of the host and the first slave computer heartbeat packet contains the information of the first slave computer; broadcasting a second heartbeat packet to the host and other slave computers by the second slave computer, wherein the second heartbeat packet contains the information of the host, the information of the first slave computer and the information of the second slave computer. Based on the bidirectional wireless communication method, the device and the terminal, the bidirectional interaction of the information between the host and the slave computers is realized. Meanwhile, the information of the host and the information of the slave computers can be forwarded among the slave computers. The interaction with the host is realized through the information sharing with other slave computers. Therefore, the success rate of communication between the slave computers and the host is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a two-way wireless communication method, device and terminal. Background technique [0002] The use of wireless technology in smart devices is becoming more and more common. However, most of the wireless communications in the market for a system composed of a master and multiple slaves are one-way, and only the slave can report to the master for operation. state, the master cannot send information to the slave. And because the distance between the master of the smart device and multiple slaves is relatively long, not all of them are within the coverage of the same wireless network, resulting in communication failure between the slave and the master. At the same time, due to the short-term disconnection of individual slaves, the communication between the slaves and the master will also fail. [0003] For the above-mentioned communication problems existing in the sy...

[0002] The use of wireless technology in smart devices is becoming more and more common, but currently on the market, most of the wireless communications for a system composed of a master and multiple slaves are one-way, and only the slave can report to the master for operation. state, the host cannot send information to the slave

And due to the long distance between the host and multiple slaves of the smart device, not all of them are within the coverage of the same wireless network, resulting in communication failure between the slave and the host

At the same time, due to the short-term disconnection of individual slaves, the communication between the slaves and the host will also fail.

[0003] Aiming at the above-mentioned communication problems existing in the system composed of master and slave in the prior art, no effective solution has been proposed yet
