1. A system for providing information about fuel efficiency of construction machinery and driving the construction machinery accordingly, comprising:

  • a hydraulic pump;

    a tele management system (TMS) controller configured to obtain information about reference fuel efficiency through a communication network from a server; and

    provide the information about the reference fuel efficiency as display information; and

    an equipment controller configured to;

    calculate information about current fuel efficiency by analyzing operations of constituent elements of the construction machinery,wherein the information about the reference fuel efficiency includes a plurality of tables and records and fields of the respective tables,wherein the plurality of tables is configured for each type of construction machinery, and the records and the fields of the tables include at least one of best fuel efficiency equipment for each operation place condition, daily best fuel efficiency equipment, weekly best fuel efficiency equipment, monthly best fuel efficiency equipment, and annually best fuel efficiency equipment,wherein the records and the fields of the tables include at least one of revolutions per minute of an engine, a discharged flow rate, horsepower, a driving speed, and a use time with no load,wherein the information about the current fuel efficiency is transmitted to the server, and compared with the information about the reference fuel efficiency,wherein the compared information is calculated as fuel efficiency learning information to be provided to an operator through a personal terminal, andwherein the fuel efficiency learning information includes a use time with no load of the best fuel efficiency equipment, a difference in the use time with no load between the best fuel efficiency equipment and current equipment, a recommended operation mode through an analysis of corresponding information, revolutions per minute of the engine, and a use time with no load required to be decreased;

    display the information about the current fuel efficiency calculated by analyzing operations of constituent elements of the construction machinery and the information about the reference fuel efficiency obtained from the TMS controller together on a gauge;

    display variances of the information about the reference fuel efficiency and the information about the current fuel efficiency according to a time in a graph form on the gauge; and

    induce generation of a manipulation signal that drives a working device of the construction machinery according to the fuel efficiency learning information, wherein hydraulic oil is outputted from the hydraulic pump to the working device according to the manipulation signal.
