Abstract

An embedded gateway for WiFi and ZigBee wireless network protocol conversion belongs to the wireless communication network technology field, the embedded gateway comprises a microprocessor, a system bus and a peripheral circuit which is connected with the microprocessor, and the peripheral circuit comprises a Flash memory, a SDRAM memory, an asynchronous serial communication port, an Ethernet interface, a JTAG interface, a USB interface, a USB wireless network card, a GPIO interface and a ZigBee wireless transceiving module. The embedded gateway has the advantages of low cost and small size, and the embedded gateway is applicable to mass production and fixed-point layout in project development; the data processing speed is fast; the reliability is high, the functions are powerful; the power consumption is lower and the embedded gateway can be used for a long time under special circumstances. The embedded gateway can realize the protocol conversion and data forwarding between the wireless ZigBee network and the wireless WiFi network, thereby realizing the interoperability between the two wireless networks.

Description

(1) Technical field [0001] The invention relates to the technical field of wireless communication networks, in particular to an embedded gateway for protocol conversion between WiFi and ZigBee wireless networks. (2) Background technology [0002] ZigBee is a two-way wireless communication technology with short distance, low complexity, low power consumption, low data rate and low cost. It works in the 2.4GHz ISM frequency band without registration, the transmission rate is 10~250kb / s, and the transmission distance is 10~75m. It looks closer to Bluetooth, but it is simpler than Bluetooth. It has the advantages of low power consumption and strong networking capabilities. Most of the time it is in sleep mode, and it is more suitable for occasions that do not require real-time transmission or continuous updates to achieve short-range wireless connect. It has its own radio standard that coordinates communication between thousands of tiny sensors. These sensors require very lit...
