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.
