Problems solved by technology

However, most of the existing interface conversion devices realize a single conversion of one interface to another interface, which is not universal
Moreover, the main idea of ​​these devices is the conversion of one interface level standard to another interface level standard, which is only the conversion of the underlying physical layer and does not involve the conversion of the upper layer net

Abstract

The invention discloses a multifunctional interface conversion device, which can realize interconversion among a USB interface, an Ethernet interface, a serial port RS232, a serial port RS422, a serial port RS485 and a CAN bus interface by installing a physical layer processing unit and a network layer processing unit corresponding to various conventional bus interfaces; realizes the setup of a work mode and the real-time display of data transmission by installing a man-machine interactive module, thus having better visuality and operability; realizes error recovery regeneration of original data information by the error recovery mechanism of the network layer protocol of various bus interfaces, thus effectively lowering the error rate of data transmission and improving the whole performance and reliability of the system; facilitates testing and functional expansion for users by installing an interface expansion module like adding a new lower computer device or a storage device; and realizes program overloading by a JTAG allocation interface, thus achieving the purpose of upgrading performance parameters.

Description

technical field [0001] The invention relates to the technical field of electronic communication, in particular to a multifunctional interface conversion device, which realizes mutual conversion and processing among various interfaces. Background technique [0002] At present, there are many bus standards in the electronic communication industry, and major electronics manufacturers or alliances have launched their own defined and designed bus standards, such as the LVDS standard proposed by National Semiconductor and Texas Instruments, and the I2C standard proposed by Philips. These standards can maintain the intellectual property barriers of various electronics manufacturers or alliances, but due to the inconsistent protocol standards, it brings great inconvenience to ordinary users when they choose products with various interfaces designed by different manufacturers for interconnection and intercommunication. Various interfaces bring great difficulties to system integration...
