Embodiment Construction

[0024] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] The invention is a multi-interface protocol bidirectional conversion device, which uses FPGA as a control core unit to realize mutual conversion among four common interface protocols of RS232, RS485, SPI and IIC.

[0026] Step 1) Prepare to build the structure diagram of the multi-interface protocol conversion device

[0027] Such as figure 1 Shown: The multi-interface protocol conversion device includes: RS232, RS485, SPI and IIC external interfaces, FPGA control unit, protocol conversion parameter configuration module, TFT display module, power supply module and clock management module. First, set the protocol conversion parameters through the protocol conversion parameter configuration module, then collect the data into the FPGA through the interface, convert the external clock through the DCM clock management module to obtain th...

Abstract

The invention discloses a multi-interface protocol bidirectional conversion device and an implementation method. According to the invention, data communication among a plurality of different application systems is realized to open up a data path among a plurality of different communication protocols. A multi-interface protocol bidirectional conversion device is designed. An FPGA serves as a core control platform and a mutual conversion module supporting four common communication protocols of RS232, RS485, SPI and IIC and a TCP/IP protocol is designed through Verilog language programming.

Description

technical field [0001] The invention specifically relates to a multi-interface protocol bidirectional conversion device and an implementation method, belonging to the technical field of various interface protocol conversions. Background technique [0002] The role of data communication and transmission in the Internet of Things is particularly important. At present, a variety of data communication protocol standards are popular. Due to the incentives of competition, no one protocol or several protocols can unify the entire market. These communication protocols are used in many fields. play an important role. This leads to different communication standards, various communication protocols, and incompatibility of protocols for a large number of sensors, which greatly reduces the operability and connectivity between devices. At present, there is no breakthrough in the architecture design of the protocol conversion system. Most of the protocol conversions are conversions betwee...
