Embodiment Construction

[0015] The technical scheme of the present invention will be further analyzed in detail below with reference to the accompanying drawings and specific examples.

[0016] Such as figure 1 A block diagram of the analyzer is shown. It includes two parts: the wireless data acquisition module and the upper computer decoding analysis part. The wireless data acquisition part includes a main controller, a 2.4GHz wireless radio frequency transceiver 1, a 2.4GHz wireless radio frequency transceiver 2, a USB interface module, and a power management module. The upper computer decoding analysis part includes system setting module, data processing module and man-machine interface.

[0017] figure 2 Shown is the schematic structure diagram of the wireless data acquisition module. The main controller adopts the newly released Cortex-M0 core of the microprocessor chip ARM Company, which is the smallest and lowest energy consumption ARM processor in the market. The wireless radio frequenc...

Abstract

The invention provides a two-channel data detection and protocol analysis meter based on 6LowPAN and a method and relates to the technical field of wireless sensor network. The analysis meter comprises a wireless data acquisition module, an upper computer decoding analysis part, a wireless RF (radio frequency) transceiver 1 and a wireless RF (radio frequency) transceiver 2. The method comprises the following steps: continuously monitoring if wireless data message exists in the channel; to the data message, packaging the message header and the channel signal by a main controller and sending to the upper computer; using an upper computer data processing module to confirm the frame type according to a frame type subsection in a frame control field of MAC (media access control) layer message header of the received data message; if being 6LowPAN packet, analyzing the protocol message header of the 6LowPAN packet layer by layer according to a protocol rule of a 6LowPAN protocol model; and performing analytic statistics and displaying on a man-machine interface.

Description

technical field [0001] The present invention relates to the technical field of wireless sensor networks, in particular to data detection and protocol analysis of 6LowPAN (IPv6 over LR_WPAN, 6LowPAN for short) wireless sensor networks. Background technique [0002] With the rapid development of wireless communication technology in the field of industrial control, an industrial wireless communication technology for information interaction between devices has emerged. In the research and development and testing of wireless sensor technology, data detection and protocol analysis between devices in the wireless sensor network are required. [0003] There are many communication network protocol analysis devices, mainly to analyze the protocol and provide specific data support for the reliability and stability of the network system. However, current protocol analyzers have many defects. First of all, the most commonly used one is the sniffer, which mainly monitors the network sta...
