Multi-interface self-adaptive wireless heterogeneous network protocol conversion method and communication device

Abstract

Provided is a multi-interface self-adaptive wireless heterogeneous network protocol conversion method and a communication device. The communication device comprises a processor connected with a SPI communication module, a RS485 / RS232 serial communication module, a CAN communication module, an Ethernet interface communication module, a SDRAM internal storage unit, a Nand Flash memory, a WIFI wireless radiofrequency transceiver module, and a ZigBee wireless radiofrequency transceiver module via a bus. The processor is used for storing a conversion mapping relation among the interfaces by means of a mode control word, autonomously analyzing and scheduling corresponding resources, achieving conversion between multiple protocols and IEEE802.11 and 802.15.4 standard protocol and wired / wireless data analysis and forwarding. The multi-interface self-adaptive wireless heterogeneous network protocol conversion method achieves data forwarding functions between different wired interfaces and different wireless interfaces so as to achieve multi-protocol multi-interface intercommunicated characteristics.

Description

technical field [0001] The invention relates to the field of embedded heterogeneous network communication, in particular to an adaptive conversion wireless heterogeneous network communication method and device with multiple interfaces. Background technique [0002] In the industrial site, the wired communication method needs to preset the engineering wiring pipeline, the construction cost is high, and it is greatly affected by the geographical environment, which is not conducive to maintenance and secondary upgrades. Simple, convenient maintenance, good adaptability and other advantages. In addition, the bus interfaces used in the industrial field bus are different, so a heterogeneous network communication device integrating multiple protocol interfaces is required. [0003] Among existing communication technologies, wired and wireless network interworking technologies are very common. For example: Chinese patent application number is: 201120572125.3, the patent named "ser...

Problems solved by technology

However, the device has a single use condition and does not take into account the communication problems between different bus interfaces

Another example, the Chinese patent application number is: 201110423393.3, the patent titled "a multi-protocol multi-interface wireless sensor network gateway", the device solves the problem of wireless / wired data fusion in the existing wireless sensor network by designing a protocol conversion program , but the device cannot meet the requirements of intelligent wired / wireless data communication between RS485 / RS232 bus, CAN bus, SPI bus equipment and wireless gateways in industrial sites

[0004] It can be seen from the above that the existing electronic communication devices are too simple in equipment and principle, and cannot intelligently select the interface mode to communicate with other different interface devices, so it is difficult to adapt to the current requirements of the electronic communication industry or industrial sites, so a new one is urgently needed Electronic communication device to solve the above problems
