Example Embodiment

[0061] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described The embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0062] Aiming at the communication process of the ZigBee system, it is relatively susceptible to interference from other interference sources, such as being easily interfered by the relatively strong signal WIFI, which causes the problems of the ZigBee signal being prone to packet loss and high bit error rate. Methods,...

Abstract

The invention provides methods and device for improving anti-interference performance of a ZigBee system and terminal equipment. Two or more antennas are set in the ZigBee system. Specifically, a radio frequency field form graph of each antenna is drawn according to receiving sensitivity of each antenna; the radio frequency field form graph of each antenna is divided into a plurality of angle intervals; through comparison of the receiving sensitivity of the radio frequency field form graph of each antenna in the same angle interval, the angle intervals with the highest receiving sensitivity are selected as valid radio frequency angle intervals; and signals received by each antenna in the selected radio frequency angle intervals are integrated as complete signals received by the antennas ofthe ZigBee system. Compared with a mode of receiving the signals through adoption of a single antenna, the mode of screening the antennas and integrating the signals received by the antennas has theadvantages that a part of interfered weak signal distribution areas in the antennas can be eliminated, transformation from weak signals to strong signals is realized, and the anti-interference performance of the ZigBee system is realized.

Description

technical field [0001] The present disclosure relates to the technical field of wireless communication, and in particular to a method, device and terminal equipment for improving the anti-interference performance of a ZigBee system. Background technique [0002] With the higher and higher requirements for the intelligence of home appliances, and the advantages of low energy consumption and low cost based on ZigBee wireless communication, many home appliances are now equipped with ZigBee wireless systems. [0003] Among them, ZigBee technology complies with the IEEE802.15.4 standard low-power LAN protocol, which is based on the 2.4GHZ wireless communication technology of the ISM (Industrial Scientific Medical) frequency band, and is in the same frequency band as WIFI and Bluetooth. With the popularization of wireless communication technology, the possibility of ZigBee and WIFI (WIreless-Fidelity, wireless fidelity) systems coexisting and working at the same time is increasing...
