Problems solved by technology

[0002] The existing RS232 and RS485 serial bus communication has low communication rate and short communication distance (the maximum transmission distance of RS232 is about 15m, and the maximum transmission rate of RS485 generally 100m long twisted pair is only 1Mb / s), and the nodes cannot Disadvantages such as free communication and difficult installation
Low communication rate will bring system positioning tracking error, and the existing multi-channel positioning control system does not have networking capability, or has RS232, USB or RS485 interface, the cable connection distance of the first two is limited, and it cannot be controlled remotely. The latter has a limited transmission rate and poor data communication capabilities

Abstract

The invention provides an Ethernet and serial port / CAN protocol conversion device based on STM32. The device comprises an STM32 embedded processor, an Ethernet interface module, an A / D module, a D / A module, a CAN transceiver, a RS232 interface module, a RS485 interface module, a storage module, a power supply module, a crystal oscillator module, a JTAG interface module, a reset module and a 74LVX4245 chip logic level conversion module, wherein the Ethernet interface module, the CAN transceiver, the RS232 interface module and the RS485 interface module are all connected with the STM32 embedded processor. The Ethernet and serial port / CAN protocol conversion device based on STM32 of the invention can achieve the function of mutual conversion of multiple communication fusion technologies.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an STM32-based Ethernet and serial port / CAN protocol conversion device. Background technique [0002] The existing RS232 and RS485 serial bus communication has low communication rate and short communication distance (the maximum transmission distance of RS232 is about 15m, and the maximum transmission rate of RS485 generally 100m long twisted pair is only 1Mb / s), and the nodes cannot Disadvantages such as free communication and difficult installation. Low communication rate will bring system positioning tracking error, and the existing multi-channel positioning control system does not have networking capability, or has RS232, USB or RS485 interface, the cable connection distance of the first two is limited, and it cannot be controlled remotely. The latter has a limited transmission rate and poor data communication capabilities. So how to design a technology that can reali...
