Zigbee protocol analyzing device

Abstract

The invention relates to an analyzing device, in particular to a Zigbee protocol analyzing device. The Zigbee protocol analyzing device comprises a radio-frequency transceiver module, a main controller module, a PC (personal computer) and a function indication module, wherein the radio-frequency transceiver module, the function indication module and the PC are connected with the main controller module respectively. The main controller module converts Zigbee signals sent by the radio-frequency transceiver module into frame signals in a USB format and then sends the signals to the PC; the main controller module judges the running state of a wireless sensing network; and the function indication module indicates the working state of the wireless sensing network. The Zigbee protocol analyzing device provides specific data support for reliability and stability of a network system, detects and analyzes the wireless sensing network constituted by Zigbee, and judges the working states of a network node, a router and a coordinator.

Problems solved by technology

However, there are many defects in the current protocol analyzers. First, the most commonly used one is the sniffer (Sniffer), which mainly monitors the network status and data flow, and monitors a single channel. It lacks the monitoring of wireless sensor networks. detection

Secondly, common protocol analyzers can only detect and analyze ZigBee signals in the ISM 2.4GHz frequency band, but when working in the ISM 780 / 868 / 915MHz frequency band, they have the characteristics of low power consumption, high sensitivity and strong penetration. In the case of the same transmission power, it has stronger penetration, longer communication distance and better communication quality than IEEE 802.15.4 in the ISM 2.4GHz frequency band

Therefore, the prior art cannot detect the ZigBee signal of the 700 / 800 / 900 frequency band, especially the 780MHz Chinese frequency band under the IEEE 802.15.4c standard
