Embodiment Construction

[0021] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0022] The present embodiment gateway (C / R) conforms to Zigbee2006 agreement standard, comprises coordinator (CD) and router (RD), adopts asynchronous serial port to establish data connection between the two; CD and RD are in different WPAN, and The other nodes of the respective networks are connected.

[0023] The device selected by the gateway in this embodiment is an SOC (System On Chip) device that organically combines an ordinary MCU (microprocessor) and an RF (radio frequency) chip, thereby minimizing the occupation of system resources by RF tasks , to ensure that limited MCU management resources are used to maintain the real-time and reliability of Zigbee network data transmission to the greatest extent.

[0024] In order to ensure the forwarding efficiency and forwarding capability of C / R, the network tries to transmit effective data in...

Abstract

The invention discloses a method for extending a Zigbee network gateway and transmitting data, which belongs to the wireless communication filed. The invention uses Zigbee protocol standard, and includes a router(RD) and a coordinator (CD) which uses asynchronous serial port to build a data connection; the router and the coordinator is respectively located in different Zigbee network, and is respectively connected to other nodes of each network. The use method includes that: the coordinate receives the data from local network and forwards the data to the router, the router transmits the data to peripheral equipment; the router receives the data from the peripheral equipment and forwards the data to the coordinate, the coordinate transmit the data to an internal plant in local network. Theinvention is also used for extending the Zigbee network.

Description

technical field [0001] The invention relates to a gateway for extending a Zigbee network and a data transmission method thereof, belonging to the field of wireless communication. Background technique [0002] Zigbee (Zigbee technology) is a new short-distance wireless communication technology with the advantages of low cost, small size and low power consumption. It works in three frequency bands, which are 868MHz, 915MHz and 2.4GHz. Among them, 2.4GHz is the universal industrial, scientific, and medical (ISM) frequency band, and the data transmission rate in this frequency band is 250kbps. The establishment of a wireless personal area network (WPAN) in this frequency band has the advantages of easy installation, short-distance communication, and data transmission. Reliable and other advantages, it is one of the preferred technologies for building wireless sensor networks. [0003] For the purpose of expanding the number of network nodes, networking layers and spatial cover...
