Abstract
At least an embodiment may provide a remote server that can predict overheating of an engine. A remote server may receives an engine rotational speed, an engine load factor, and a cooling-water temperature. The remote server calculates a moving average of the engine load factor during a predetermine time, and calculates a correlation between the moving average of the engine load factor and the cooling-water temperature. If the correlation during a predetermined period is in the status of a predetermined difference from the correlation up to the predetermined period, the remote server predicts occurrence of overheating in a swing working vehicle that is used by a user.
Claims4
A remote server that receives information on a rotational speed of an engine, information on a load factor of the engine, and information on a temperature of cooling water of the engine, wherein
- the remote server calculates a moving average of the load factor during a predetermined time, and calculates a correlation between the moving average of the load factor of the engine and the temperature of the cooling water, and if the correlation during a predetermined period is in a status of a predetermined difference from the correlation before the predetermined period, the remote server predicts occurrence of overheating.
A remote server that receives information on a rotational speed of an engine, information on a load factor of the engine, and information on a temperature of cooling water of the engine, wherein
- the remote server calculates an engine output from the information on the rotational speed of the engine and the information on the load factor of the engine, calculates a moving average of the engine output during a predetermined time, and calculates a correlation between the moving average of the engine output and the temperature of the cooling water, and if the correlation during a predetermined period is in a status of a predetermined difference from the correlation before the predetermined period, the remote server predicts occurrence of overheating.
