Problems solved by technology

[0002] In recent years, due to the respective advantages of wifi technology, bluetooth technology and zigbee technology, they have all made great progress in their respective related fields. However, since the frequency band used by these three modes is 2.4GHz, the mode gateway, the problem of radio frequency coexistence and mutual interference will inevitably occur
When these kinds of services interfere with each other seriously, the respective transmission quality will be greatly reduced, which will easily cause communication blockage or interruption, which will seriously affect user experience.
[0003] At present, there are some methods for suppressing mutual interference, which need to change the frame structure of information transmission, and need to greatly modify the software system architecture of the original module, which is very complicated and error-prone to implement; some even need to modify the hardware structure of the original module , increase hardware overhead, this method will lead to cost increase and system structure changes, it is not suitable for existing mature modules

specific Embodiment approach

[0041] The following describes the specific implementation as follows:

[0042]According to the actual situation, set the priorities of the wifi module, the bluetooth module and the zigbee module respectively: the wifi module has the highest priority, the bluetooth module has the lowest priority, and the zigbee module has the lowest priority. Then the wifi module needs to have a high packet sending rate, the bluetooth module needs to have two kinds of high and medium packet sending rates, and the zigbee module needs to have three kinds of high, medium and low packet sending rates. If the priority settings are different, the corresponding module needs to have a corresponding packet sending rate.

[0043] Case 1: No module is currently communicating, and the Bluetooth module requests to initiate communication, then set the packet sending rate of the Bluetooth module to high. If no other module requests to initiate communication before the Bluetooth module communication is compl...

Abstract

The invention discloses an anti-mutual interference method of a multimode gateway, and belongs to the technical field of Internet information interaction. The anti-mutual interference method comprises the following steps: controlling the priority of multiple different types of communication modules and packet delivery rates corresponding to the priority with a master control module on the multimode gateway, so as to implement the anti-mutual interference communication among the communication modules. The communication modules comprise a wifi module, a Bluetooth module and a zigbee module. The priority of the communication modules is set and controlled through the master control module; the master control module dynamically regulates the packet delivery rate of the modules according to the priority of multiple modules and the communication requesting conditions of the communication modules, so that the probability of collisions between data packets of the modules is reduced, the mutual interference between the modules is improved, the stability of data transmission is enhanced, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of Internet information interaction, in particular to an anti-interference method of a multi-mode gateway. Background technique [0002] In recent years, due to the respective advantages of wifi technology, bluetooth technology and zigbee technology, they have all made great progress in their respective related fields. However, since the frequency band used by these three modes is 2.4GHz, the For the gateway of the mode, there will inevitably be the problem of radio frequency coexistence and mutual interference. When these types of services interfere with each other seriously, the respective transmission quality is greatly reduced, which may easily cause communication blockage or interruption, thereby seriously affecting user experience. [0003] At present, there are some methods for suppressing mutual interference, which need to change the frame structure of information transmission, and need to greatly m...
