Wireless multi-channel communication device and multi-channel real-time communication method

Abstract

The invention discloses a wireless multi-channel communication device and a multi-channel real-time communication method. The device comprises receiving units, sending units and a central coordination processing unit, wherein the receiving units are used for receiving data on a set wireless channel, the sending units are used for sending data on an appointed wireless channel, and the central coordination processing unit is electrically connected with the receiving units and the sending units and used for acquiring the data received by the receiving units in real time. When data need to be emitted, an idle wireless channel used by the sending units is appointed according to states of the current wireless channels, and the data needing to be sent on the idle wireless channel are transmitted to the sending units. By means of the device and method, the conditions of the channels can be monitored at the same time, accurate channel busy and idle distinguishing threshold values are acquired according to effectively receiving and continuous sampling, whether collisions or distortion is produced or not can be judged according to a data package emitted by the device, very high real-time performance is achieved, and communication delay caused by channel conflict can be avoided.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a wireless multi-channel communication device and a multi-channel real-time communication method. Background technique [0002] At present, most of the communication devices in the wireless communication network transmit and receive data for a single channel, and there is a competition for channel use rights among the communication nodes in the wireless communication network. When two or more wireless signals are sent at the same time, the communication will be destroyed due to the mutual interference of the signals. There have been a variety of channel competition protocols to solve this problem, but the essence is to organize the nodes that need to send wireless signals at the same time sequentially, which will cause communication delays for some nodes. In situations where real-time wireless communication is required, this delay is unbearable, such as communicat...

[0002] At present, most of the communication devices in the wireless communication network transmit and receive data for a single channel, and there is a competition for channel use rights among the communication nodes in the wireless communication network. When two or more wireless signals are sent at the same time, the communication will be destroyed due to the mutual interference of the signals.

There have been a variety of channel competition protocols to solve this problem, but the essence is to organize the nodes that need to send wireless signals at the same time in sequence, which will cause communication delays for some nodes

In situations where real-time wireless communication is required, this delay is unbearable, such as communication between cars driving on the highway through a vehicle-mounted wireless system, and the interaction of driving information through wireless signals is required to provide drivers with more safety guarantees In this case, the delay of hundreds of milliseconds caused by wireless communication conflicts may cause accidents between vehicles
