  "abstract": "An industrial vehicle work guide system is disclosed. An industrial vehicle work guide system according to an embodiment of the present invention includes: a memory configured to store engine used data, a driving time, a fuel consumption amount, and reference fuel efficiency; a display module configured to output a guide message; and an analysis module configured to calculate actual fuel efficiency by using the engine used data, the driving time, and the fuel consumption amount, compare the actual fuel efficiency with the reference fuel efficiency, and control the display module so that the display module outputs a guide message when the actual fuel efficiency is lower than the reference fuel efficiency.",
  "claims": [
    "1. An industrial vehicle work guide system, comprising: a memory configured to store engine used data, a driving time, a fuel consumption amount, and reference fuel efficiency; a display module configured to output a guide message; an analysis module configured to calculate actual fuel efficiency by using the engine used data, the driving time, and the fuel consumption amount, compare the actual fuel efficiency with the reference fuel efficiency, and control the display module so that the display module outputs a guide message when the actual fuel efficiency is lower than the reference fuel efficiency; and a load sensor configured to measure weight of the cargo loaded on the industrial vehicle, wherein the reference fuel efficiency includes a work amount per hour defined with a work cycle per driving time, and wherein the analysis module is configured to define one work cycle from a time point in which a pressure sensed by the load sensor is increased to a time point in which the pressure sensed by the load sensor is decreased, to calculate the number of work cycles based on the pressure measured by the load sensor, and to calculate the work amount per hour using the calculated work cycles.",
    "2. The industrial vehicle work guide system of claim 1, wherein the engine used data includes information about an engine speed and an engine output.",
    "3. The industrial vehicle work guide system of claim 2, wherein the analysis module extracts a most frequently used engine speed from the engine used data, compares the most frequently used engine speed with a preset most efficient engine speed, and outputs the guide message through the display module so that the most frequently used engine speed is close to the most efficient engine speed.",
    "4. The industrial vehicle work guide system of claim 1, wherein the reference fuel efficiency is fuel efficiency when reference work consisting of two or more of load loading/unloading work, inching work, traveling work, and complex operation work is performed.",
    "5. The industrial vehicle work guide system of claim 1, wherein the reference fuel efficiency includes fuel efficiency defined with a fuel consumption amount per driving time.",
    "6. The industrial vehicle work guide system of claim 1, wherein the reference fuel efficiency includes work efficiency defined with a fuel consumption amount per work cycle.",
    "7. The industrial vehicle work guide system of claim 1, wherein the reference fuel efficiency is set based on each cargo located on the industrial vehicle and each engine speed."

  "description_excerpt": "The present invention relates to an industrial vehicle work guide system.\n\nA forklift is a representative industrial vehicle used for lifting and loading and unloading cargo having relatively large weight or used for lifting cargo having large weight and transporting the cargo to a position desired by a worker. An excavator operates working machinery by using an operation lever, an operation pedal, and the like within a cabin or an operating room. When the operation lever, the operation pedal, and the like are operated in the state where the forklift starts, a hydraulic cylinder or a hydraulic actuator is operated, so that the working machinery performs work.\n\nThe representative work of the forklift is work of lifting and loading and unloading cargo having large weight, work of transporting cargo, and the like, and in the repeated work, it is known that a work operation pattern of a skilled operator improves efficiency of an operation capacity and considerably improves fuel efficiency.",
