Abstract

The invention relates to a ZigBee network based multi-gateway transmission system, in particular toa multi-gateway transmission system of the single ZigBee network with same domain network markers. Reported data in the network are divided into multiple parts to transmit to a plurality of gateways, and the gateways perform data conversion between the sensor network and the Ethernet. The ZigBee network based multi-gateway transmission system mainly comprises a terminal node, a routing node, a gateway node and a PC (personal computer) server, wherein the terminal node is connected with a sensor and / or controlled equipment and used for reporting acquired sensor data to a father node, the routing node is used for selecting the optimum reported gateway and transferring data, the gateway node is used for completing data address and protocol conversion between the ZigBee network and the Ethernet, and the PC server is used for gathering data of the gateways to centralized process. The ZigBee network based multi-gateway transmission system can adjust the number of the gateways and can solve the problem of network time delay caused by massive data according to needs.

Description

technical field

[0001] The invention belongs to the technical field of wireless communication, and relates to a ZigBee network-based multi-gateway transmission system, in particular to a single ZigBee network multi-gateway transmission system with the same personal area network identifier. Background technique

[0002] ZigBee (transliterated as "Zigbee" in Chinese) is an emerging short-distance, low-speed wireless network technology, which has the advantages of low power consumption, low cost, low complexity, and flexible networking, and is gaining popularity in wireless sensor network applications. More and more attention. ZigBee protocol layers from bottom to top are physical layer (PHY), media access control (MAC) layer, network layer (NWK), application layer (APL), etc. Among them, MAC layer and PHY layer adopt IEEE 802.15.4 protocol standard , the upper layer protocol is defined and standardized by the ZigBee Alliance. ZigBee can work in three frequency bands of 868MH...
