Agricultural work vehicle and system and method for monitoring state of agricultural work vehicle

A system for monitoring a state of an agricultural work vehicle, the system comprising:

• a state information receiving device that receives state information of an agricultural work vehicle from one or more agricultural work vehicles when a working machine attached to the agricultural work vehicle performs agricultural work;
• a monitoring device that determines at least one of whether there is an abnormality in a temperature of a coolant for the agricultural work vehicle, whether there is an abnormality in a pressure of an engine oil, and whether there is an abnormality in an engine when the working machine performs work based on the state information;
• and
• a determination result transmitting device that transmits a result of determination to a driver terminal of the agricultural work vehicle when a determination is made that an abnormality occurs in at least one of the temperature of the coolant, the pressure of the engine oil, and the engine,
• wherein the monitoring device calculates a difference between an outside air temperature of a place in which the agricultural work vehicle is located and a current temperature of the coolant and determines that an abnormality occurs in the temperature of the coolant when the difference departs from a predetermined normal range.

A method for monitoring a state of an agricultural work vehicle, the method comprising:

• causing an agricultural work vehicle to acquire state information of the agricultural work vehicle when a working machine attached to the agricultural work vehicle performs agricultural work;
• causing the agricultural work vehicle to transmit the state information of the agricultural work vehicle to a control server ;
• causing the control server to determine at least one of whether there is an abnormality in a temperature of a coolant for the agricultural work vehicle, whether there is an abnormality in a pressure of an engine oil, and whether there is an abnormality in an engine when the working machine performs work based on the state information;
• causing the control server to transmit a result of determination to a driver terminal of the agricultural work vehicle when a determination is made that an abnormality occurs in at least one of the temperature of the coolant, the pressure of the engine oil, and the engine;
• and
• causing the driver terminal to display the result of determination received from the control server to a driver,
• wherein a difference between an outside air temperature of a place in which the agricultural work vehicle is located and a current temperature of the coolant is calculated and a determination is made that an abnormality occurs in the temperature of the coolant when the difference departs from a predetermined normal range.
