A multi-input zigbee receiving device and method thereof

Abstract

The invention relates to a multi-input Zigbee receiving device which comprises two or more radio frequency antennas, a radio frequency module, a detection module, a data processing module, a memory and a combiner. The two or more radio frequency antennas are respectively connected with the radio frequency module, and the radio frequency module, the detection module, the data processing module, the memory and the combiner are connected mutually in sequence according to a signal processing flow. The invention further provides a multi-input Zigbee receiving method. According to the multi-input Zigbee receiving device, due to the fact that a plurality of antennas independent mutually are adopted, the sensitivity of system received signals is improved greatly, moreover interference and attenuation of erasure signals are improved greatly, the multi-input Zigbee receiving device can also be suitable for a complex environment, and the problems of a single-input mode in the complex environment are solved, wherein the problems include that in a wireless multipath transmission process, the quality of received signals is reduced seriously, even no signals are received, the signal cover is reduced sharply, thruput or a frequency spectrum of the received signals is reduced obviously and the like.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically, relates to a multi-input Zigbee transmitting device and a method thereof. Background technique [0002] Zigbee (short-range, low-power wireless communication technology) is an emerging wireless network technology with short-distance, low complexity, low power consumption, low data transmission rate, and low cost. A technical proposal between Bluetooth, which is mainly used for short-range wireless connections. It coordinates and communicates among thousands of tiny sensors based on the 802.15.4 standard. These sensors require very little power to relay data from one sensor to another via radio waves, so they communicate very efficiently. [0003] The existing Zigbee technology uses a single-channel input mode. The Zigbee module in this single-channel input mode is easily affected by the field environment. In a relatively complex environment, the sig...
