Abstract

A management server for a working machine, including: a reception unit that receives a sensor output from a working machine; a regular report creation unit that creates, for each predetermined period of time, a regular report indicating an operation state of the working machine within the predetermined period of time based on the sensor output; an emergency report creation unit that creates at least one emergency report upon detecting abnormality data representing abnormality of the working machine based on the sensor output; an important report creation unit that creates an important report upon detecting predictive data indicating a sign of the abnormality based on the sensor output; and a delivery unit that delivers the regular report, the at least one emergency report, and the important report, respectively, to a regular report delivery target, an emergency report delivery target, and an important report delivery target.

Claims

1. A management server (500) for a working machine, comprising:

a reception unit (510) (S400) that receives a sensor output from the working machine (100);

a regular report creation unit (510) (S330) that creates, for each predetermined period of time, a regular report (150) indicating an operation state of the working machine within the predetermined period of time based on the sensor output;

an emergency report creation unit (510) (S450) that creates at least one emergency report (250) (350) upon detecting abnormality data representing abnormality of the working machine based on the sensor output;

an important report creation unit (510) (S500) that creates an important report (450) upon detecting predictive data indicating a sign of the abnormality based on the sensor output; and

a delivery unit (510) (S350) (S470) (S520) that delivers the regular report, the at least one emergency report, and the important report, respectively, to a regular report delivery target, an emergency report delivery target, and an important report delivery target.

2. The management server for a working machine according to claim 1, further comprising:

a first data base (700) that stores first information relating to a language; and

a language determination unit (510) (S320) (S440) (S490) that determines the language referring to the first information, wherein;

the regular report creation unit, the emergency report creation unit, and the important report creation unit creates the regular report, the at least one emergency report, and the important report in the language determined by the language determination unit.

3. The management server for a working machine according to claim 2, further comprising:

a delivery target identification unit (510) (S340) (S460) (S510) that identifies the regular report delivery target, the emergency report delivery target, and the important report delivery target, wherein;

in the first database, second information relating to the regular report delivery target, the emergency report delivery target, and the important report delivery target is further stored; and

the delivery target identification unit refers to the second information to identify

as the emergency report delivery target, a first delivery target that corresponds to a purchaser of the working machine and a second delivery target that corresponds to a seller of the working machine,

as the important report delivery target, the second delivery target that corresponds to the seller, and

as the regular report delivery target, the first delivery target that corresponds to the purchaser and the second delivery target that corresponds to the seller.

4. The management server for a working machine according to claim 1, further comprising:

a second database (600) that stores third information relating to tuning executed to the working machine by an external terminal device; and

a control unit (510) that receives the third information from the external terminal device and stores the received third information at the second database, wherein;

if the second database stores the third information when creating the regular report, the regular report creation unit creates the regular report including the third information.

5. The management server for a working machine according to claim 1, wherein:

the regular report creation unit additionally describes in the regular report an average value of any one of fuel consumption, operation fluid temperature, water temperature, and pump pressure based on sensor outputs from a plurality of other working machines of the same model as the working machine.

6. The management server for a working machine according to claim 1, wherein:

the emergency report creation unit switches a mode for detection of the abnormality data depending on a type of the sensor output to one selected from a mode in which the abnormality data is detected if the sensor output exceeds a predetermined threshold value once (S4310), a mode in which the abnormality data is detected if the sensor output exceeds the predetermined threshold value a plurality of times consecutively (S4350), or a mode in which the abnormality data is detected if the sensor output exceeds the predetermined threshold time a specified number of time within a fixed period of time (S4330), when detecting the abnormality data based on the sensor output.

7. The management server for a working machine according to claim 3, wherein:

the at least one emergency report includes a first emergency report and a second emergency report that contains an amount of information larger than the first information; and

the delivery target identification unit identifies the first delivery target that corresponds to the purchaser as the emergency report delivery target that corresponds to the first emergency report, and the second delivery target that corresponds to the seller as the emergency report delivery target that corresponds to the second emergency report.

8. The management server for a working machine according to claim 1, wherein:

at least one of the regular report creation unit, the emergency report creation unit, and the important report creation unit indicates, as an item of fuel consumption of the working machine to be described in at least one report selected from the regular report, the at least one emergency report, and the important report, in an item indicating region provided corresponding to a date indicating region in which a numerical value of each date within the predetermined period of time is indicated, the fuel consumption on the each date corresponding to the numerical value indicated in the date indicating region; and

in the at least one report, the date indicating region and the item indicting region are arranged in numbers corresponding to a number of days within the predetermined period of time in a matrix form.

9. A method for managing a working machine, comprising:

receiving a sensor output from the working machine;

creating, for each predetermined period of time, a regular report (150) that indicates an operation state of the working machine within the predetermined period of time based on the sensor output;

creating at least one emergency report (250) (350) each time when abnormality data representing abnormality of the working machine is detected based on the sensor output;

creating an important report (450) each time when predictive data indicating a sign of the abnormality is detected based on the sensor output; and

delivering the regular report, the at least one emergency report, and the important report, respectively, to a regular report delivery target, an emergency report delivery target, and an important report delivery target, which are predetermined in advance.

10. The method for managing a working machine according to claim 9, wherein

a mode for detection of the abnormality data is switched depending on a type of the sensor output to one selected from a mode in which the abnormality data is detected if the sensor output exceeds a predetermined threshold value once, a mode in which the abnormality data is detected if the sensor output exceeds the predetermined threshold value a plurality of times consecutively, and a mode in which the abnormality data is detected if the sensor output exceeds the predetermined threshold time a specified number of time within a fixed period of time, when detecting the abnormality data based on the sensor output.
