Refueling management system

The invention discloses a refueling management system comprising a data server, a modem, a serial port server, and multiple refueling machines. The data server is configured to be connected to the serial port server through the modem to output or receive network data. The serial port server is configured to be connected to the multiple refueling machines to output control signals or receive state signals. The serial port server of the refueling management system completely replaces a multi-serial port card in function. The problems existing in the use of a multi-serial port server are solved. The embedded programmable serial port server is easier to use and more convenient to install.
