Zigbee and Z-Wave technology-based wireless gateway

Abstract

The invention relates to a Zigbee and Z-Wave technology-based wireless gateway, which comprises a Z-Wave antenna, a Z-Wave module, a protocol conversion module, a Zigbee module and two or more Zigbee antennas, which are connected with one another in sequence, wherein the Zigbee module is a multi-input multi-output wireless Zigbee module. According to the wireless gateway disclosed by the invention, the problem of relative fluent interconnection and interworking between a Z-Wave wireless communication network and a Zigbee wireless network is solved, and a system adopting the gateway is enabled to have a wider signal covering range without laying too many communication nodes through the Z-Wave and Zigbee technology; the wireless gateway has the advantages of simple structure, lower cost, less energy consumption, higher efficiency and the like; besides, by adopting the multi-input multi-output Zigbee technology, the gateway is higher in signal sensitivity, and the signal reception throughput is improved.

Description

technical field [0001] The present invention relates to the field of wireless communication, more specifically, to a wireless gateway based on Zigbee and Z-Wave technology. Background technique [0002] Z-Wave is an emerging short-range wireless communication technology based on radio frequency, low cost, low power consumption, high reliability, and suitable for networks. The working frequency band is 908.42MHz (USA) ~ 868.42MHz (Europe), using frequency shift keying FSK (BFSK / GFSK) modulation mode, the data transmission rate is 9.6kbps, the effective coverage of the signal is 30m indoors, and more than 100m outdoors , suitable for narrow bandwidth applications. With the increase of communication distance, the complexity, power consumption and system cost of equipment are all increasing. Compared with various existing wireless communication technologies, Z-Wave technology will be the technology with the lowest power consumption and lowest cost, which will effectively Drivi...

Problems solved by technology

When two or more networks with different protocols are in the process of signal transmission and data access, the gateway needs to perform protocol conversion to achieve communication. At present, in the field of smart home applications, Zigbee wireless communication and Z-Wave wireless communication are The two most commonly used communication methods, but there is no gateway for Zigbee wireless communication and Z-Wave wireless communication to realize the protocol conversion between the two. Moreover, most Zigbee gateways currently use single input or single output The signal transmission mode, when in a relatively complex environment, the signal will be interfered and attenuated by the external environment during the on-site transmission process, and the receiving sensitivity is low, so that the signal quality received by the system will be seriously reduced, or even no signal can be received
