Abstract

The invention discloses a multi-serial port communication protocol converter based on an ARM. The multi-serial port communication protocol converter based on the ARM comprises a microprocessor, a plurality of expansion serial ports, a CAN interface and a data acquisition module. The expansion serial ports access the microprocessor through a serial port management module. The CAN interface access the microprocessor through a CAN controller. The data acquisition module is connected to the microprocessor through an A/D converter. The microprocessor is also provided with a network module and a memory. The beneficial effects of the present invention are that: networking and centralized management of the serial port devices are realized, and serial port data of exiting devices such as RS232, RS485 on industrial sites is converted to TCP/IP data, and data storage and management are carried out through an IP network.

Description

technical field [0001] The invention relates to a protocol converter, in particular to an ARM-based multi-serial port communication protocol converter. Background technique [0002] Protocol converter, referred to as co-conversion, also called interface converter, protocol converter is gateway, it can make hosts on the communication network using different high-level protocols still cooperate with each other to complete various distributed applications. [0003] With the advent of the network economy era, the IP network based on the TCP / IP protocol has been widely used, and the network access of equipment can be realized by using network resources. Equipment networking monitoring has become the development trend of industrial automation. [0004] The transformation of the existing serial port to TCP / IP communication protocol is to realize the remote monitoring and management of industrial field equipment, but this kind of protocol converter is generally a single serial port,...
