  The fuel supply timing determination means P2 is configured to determine the fuel supply timing for each model information and machine number information based on the model supply information received by the reception control means P1 and the fuel supply information for each machine number information. In this example, the fuel supply timing is determined by detecting opening / closing information indicating whether or not a door (specifically, a fuel supply cap 170a) in the fuel tank 170 is opened / closed.

  The irregular fuel mixture detection means P3 is irregular depending on the difference between the engine exhaust temperature Te and the reference engine exhaust temperature Ts after the fuel supply timing for each model information and machine number information determined by the fuel supply timing determination means P2. It is configured to detect mixing of fuel for each model information and machine number information.

  Specifically, the storage unit 134 converts the engine speed C and the engine load factor R into a reference engine exhaust temperature Ts that is an engine exhaust temperature with normal fuel corresponding to the engine load factor R with respect to the engine speed C. A first conversion table TB1 (see FIG. 8 described later) is preset (stored) for each model information.

  Of the components in FIG. 7, components that are not described will be described later.

  FIG. 8 is a chart showing an example of the first conversion table TB1 of the reference engine exhaust temperature Ts with the normal fuel according to the engine load factor R with respect to the engine speed C.

  As shown in FIG. 8, in the first conversion table TB1, for example, the engine speed exceeds 0 rpm (revolution per minute) to 200 rpm or less, exceeds 200 rpm to 400 rpm, exceeds 400 rpm to 600 rpm, exceeds 600 rpm. 800 rpm or less, 800 rpm to 1000 rpm, 1000 rpm to 1200 rpm, 1200 rpm to 1400 rpm, 1400 rpm to 1600 rpm, 1600 rpm to 1800 rpm, 1800 rpm to 2000 rpm or less The engine load factor exceeds 0% to 10% or less, exceeds 10% to 20% or less, exceeds 20% to 30% or less, exceeds 30% to 40% or less, exceeds 40% to 50% 50% below The engine speed is divided into 10 categories: 60% or less, 60% to 70%, 70% to 80%, 80% to 90%, 90% to 100%. A temperature range of the reference engine exhaust temperature Ts corresponding to each section of the engine load factor for each section is set in advance. The temperature range of the reference engine exhaust temperature Ts can be obtained in advance through experiments or the like.

  The irregular fuel mixture detection means P3 (see FIG. 7) determines that the engine exhaust temperature Te is the reference engine exhaust temperature in the first conversion table TB1 from the time when the fuel supply timing determination means P2 determines that the fuel has been supplied. When it is within the temperature range of Ts, it is detected that the regular fuel is supplied to the fuel tank 170, and when it is not within the temperature range, it is detected that the irregular fuel is mixed into the fuel tank 170. It is supposed to be configured.

  In addition, the storage unit 134 (see FIG. 7) is provided with an initial state flag FL indicating an initial state (new state) in which no fuel has been supplied in the agricultural machine 110 for each model information and machine number information. In the initial state of the agricultural machine 110, the initial state flag FL for each model information and machine number information is in an off state (specifically, “0”).

  By the way, in the agricultural tanks 110,..., Normal fuel is normally stored in the initial state (when delivered).

  Therefore, in the present embodiment, the storage unit 134 includes a normal number corresponding to the engine load factor R with respect to the engine speed C from the engine speed C and the engine load factor R instead of or in addition to the first conversion table TB1. A second conversion table TB2 (see FIG. 9 to be described later) for conversion to the reference engine exhaust temperature Ts with the fuel is set (stored) for each model information.

  The control unit 132 includes a conversion table generating unit P4 (see FIG. 7) that generates the second conversion table TB2 for each model information.

  Specifically, the conversion table generating unit P4 performs the initial fuel supply from the initial state of each agricultural machine 110,... (Specifically, the initial state flag FL in the storage unit 134 is off) by the fuel supply timing determination unit P2. Model information and machine received by the reception control means P1 from each agricultural machine 110,... Until it is determined that there is (specifically, until the ON state of the initial state flag FL in the storage unit 134 is determined) The second conversion table of the storage unit 134 for each model information, with the temperature range from the minimum value to the maximum value of the engine exhaust temperature Te corresponding to the engine load factor R for the actual engine speed C for each number information as the reference engine exhaust temperature Ts. Set (store) in TB2. It should be noted that the temperature range of the reference engine exhaust temperature Ts set in the second conversion table TB2 can be set after a predetermined time has elapsed (after the engine exhaust temperature Te has stabilized to some extent). When the conversion table generating unit P4 determines that the first fuel supply has been made, the conversion table generating unit P4 cancels the initial state for each model information and machine number information (specifically, the initial state flag FL in the storage unit 134 is turned on). State "1").

  FIG. 9 is a chart showing an example of the second conversion table TB2 of the reference engine exhaust temperature Ts with the normal fuel according to the engine load factor R with respect to the engine speed C. The blank portion of the reference engine exhaust temperature Ts in FIG. 9 obtains the engine exhaust temperature Te corresponding to the engine load factor R with respect to the engine speed C until it is determined from the initial state that the first fuel supply has been performed. This indicates that there is no engine exhaust temperature data.

  Then, the irregular fuel mixture detection means P3 (see FIG. 7) determines that the engine exhaust temperature Te is the reference engine exhaust temperature in the second conversion table TB2 from the time when the fuel supply timing determination means P2 determines that the fuel is supplied. When it is within the temperature range of Ts, it is detected that the regular fuel is supplied to the fuel tank 170, and when it is not within the temperature range, it is detected that the irregular fuel is mixed into the fuel tank 170. It is supposed to be configured.

  By the way, the engine exhaust temperature Te usually changes according to the outside air temperature To. That is, the higher the outside air temperature To, the higher the engine exhaust temperature Te, and the lower the outside air temperature To, the lower the engine exhaust temperature Te.

  In this regard, in the present embodiment, in the storage unit 134, the first conversion table TB1 is preset (stored) for each set temperature range of the outside air temperature To, and the first conversion table TB1 is stored for each set temperature range of the outside air temperature To. 2 conversion table TB2 is set (stored).

  In this example, the first conversion table TB1 and the second conversion table TB2 are not shown, but the conversion table when the outside air temperature is 0 ° C. or lower and the conversion when the outside air temperature is higher than 0 ° C. and lower than 15 ° C. A table, a conversion table when the temperature exceeds 15 ° C. and 30 ° C. or less, a conversion table when the temperature exceeds 30 ° C. and 45 ° C. or less, and a conversion table when the temperature exceeds 45 ° C. Yes. In the example shown in FIGS. 8 and 9, the first conversion table TB1 and the second conversion table TB2 in the case where the outside air temperature exceeds 15 ° C. and is 30 ° C. or less are illustrated.

  In the present embodiment, the control unit 132 identifies the management source of the agricultural machine 110 based on the identification information (specifically, model information and machine number information) from which the irregular fuel has been detected. It is configured to further include mixing notification means P5 (see FIG. 7) for notifying that there is a possibility that an irregular fuel has been mixed into the agricultural machine 110 corresponding to the identification information.

  Specifically, the mixing notification means P5 is a management source of the agricultural machine 110 (for example, a rental company that manages the agricultural machine 110 or the like corresponding to the identification information (specifically, model information and machine number information) that detected the irregular fuel. (E-mail address of the service center) is identified, and the identified management source is notified that there is a possibility that the irregular fuel has been mixed in the agricultural machine 110 corresponding to the identification information in which the irregular fuel has been detected (for example, the agriculture concerned) Send an email to the email address of the rental company or service center that manages the machine 110).

  Further, in the present embodiment, the control unit 132 stores the possibility that the irregular fuel is mixed as a history in association with the identification information (specifically, model information and machine number information) in which the irregular fuel is detected. The storage unit P6 (see FIG. 7) is further provided.

  Specifically, the history storage unit P6 identifies the identification information that detected the irregular fuel and information indicating that the irregular fuel has been detected in association with the management source corresponding to the identification information (in this example, when the irregular fuel is detected). The date and time of the irregular fuel detection) is stored in the storage unit 134.

  FIG. 10 is a schematic diagram schematically showing a data structure including identification information, management source information, and irregular fuel detection date and time stored in the storage unit 134 when irregular fuel is detected.

  As shown in FIG. 10, when the irregular fuel is detected, the storage unit 134 detects the irregular fuel for the management source information corresponding to the identification information (specifically, model information and machine number information). In addition to the date, the engine speed C, the engine load factor R, the engine exhaust temperature Te, and the outside air temperature To are sequentially stored.

(Operation example by the control unit in the remote server of the first embodiment)
Next, an operation example by the control unit 132 in the remote server 130 of the first embodiment will be described below with reference to FIG.

  FIG. 11 is a flowchart illustrating an example of a control operation by the control unit 132 in the remote server 130 according to the first embodiment.

  In the flowchart shown in FIG. 11, the control unit 132 first obtains the acquisition date and time, position information G, fuel supply information F, engine speed C, engine load factor R, engine exhaust temperature Te, and outside air temperature To by the reception control means P1. Are received for each piece of identification information from each agricultural machine 110 (step S10).

  Next, has the controller 132 determined by the fuel supply timing determination means P2 that the first fuel supply has been made from the model information corresponding to the identification information received in step S10 and the fuel supply information for each unit number information? If it is determined whether or not the first fuel supply has been made (step S11: Yes), the initial state flag FL of the corresponding model information and machine number information is turned on “1”. In step S12, the process proceeds to step S13. In other cases (step S11: No), the process proceeds to step S13 as it is.

  Next, the control unit 132 has generated the second conversion table TB2 of the corresponding model information and the outside air temperature To (for example, the temperature range of the reference engine exhaust temperature Ts of the second conversion table TB2 shown in FIG. 9). It is determined whether or not all the data is available (step S13). If the second conversion table TB2 has been generated (step S13: Yes), the process proceeds to step S16 while the second conversion table TB2 Is not generated (step S13: No), the process proceeds to step S14.

  Next, the control unit 132 determines the on / off state of the initial state flag FL (step S14), and when the initial state flag FL is the on state “1” (when the agricultural machine 110 is not in the initial state) ( On the other hand, if the off state is “0” (when the agricultural machine 110 is in the initial state) (step S14: off state), the process proceeds to step S15.

  Next, the control unit 132 uses the engine speed C, the engine load factor R, the engine exhaust temperature Te, and the outside air temperature To sent from each agricultural machine 110 in step S10 by the conversion table generating unit P4. The second conversion table TB2 of the corresponding model information and the temperature range of the outside air temperature To (for example, the temperature range of ˜0 ° C., 0 ° C. to 15 ° C., 15 ° C. to 30 ° C., 30 ° C. to 45 ° C., 45 ° C.) Generate (step S15). For example, when the engine speed C is 1500 rpm, the engine load factor R is 55%, the engine exhaust temperature Te is 458 ° C., and the outside air temperature To is 25 ° C., the second conversion of 15 ° C. to 30 ° C. is performed as shown in FIG. In the table TB2, 458 ° C. is set as the maximum value of the engine exhaust temperature corresponding to the engine load factor of 50% to 60% with respect to the engine speed of 1400 rpm to 1600 rpm.

  Next, the control unit 132 selects the first conversion table TB1 and the second conversion table TB2 from the outside air temperature To by the irregular fuel mixture detection means P3 (step S16). For example, when the outside air temperature To is 25 ° C., the first conversion table TB1 and the second conversion table TB2 of 15 ° C. to 30 ° C. are selected.

Next, the control part 132 respond | corresponds to the engine load factor R with respect to the engine speed C received by step S10 in 2nd conversion table TB2 (refer FIG. 9) selected by step S16 by the irregular fuel mixing detection means P3. It is determined whether or not there is data in the temperature range of the reference engine exhaust temperature Ts (step S17). If the data does not exist (step S17: No), the process proceeds to step S18 while the data exists. If yes (step S17: Yes), the process proceeds to step S19 .
Next, the control unit 132 supplies the fuel supply determined by the fuel supply timing determination unit P2 in the second conversion table TB2 selected in step S16 by the engine exhaust temperature Te received in step S10 by the irregular fuel mixture detection unit P3. It is determined whether or not the engine exhaust temperature Ts is within the temperature range of the reference engine exhaust temperature Ts corresponding to the engine load factor R with respect to the engine speed C after the time (step S19), and the engine exhaust temperature Te is within the temperature range of the reference engine exhaust temperature Ts. If the engine exhaust temperature Te is not within the range (step S19: No), it is assumed that there is an irregular fuel mixture and the process proceeds to step S20. On the other hand, if the engine exhaust temperature Te is within the temperature range of the reference engine exhaust temperature Ts ( Step S19: Yes), it is considered that the irregular fuel has been mixed, and the process directly proceeds to Step S22. For example, when the engine speed C is 1500 rpm, the engine load factor R is 55%, and the outside air temperature To is 25 ° C., as shown in FIG. 9, the engine speed 1400 rpm˜ When the engine exhaust temperature Te is 460 ° C. in the temperature range 455 ° C. to 458 ° C. of the reference engine exhaust temperature Ts corresponding to the engine load factor 50% to 60% with respect to 1600 rpm (step S19: No), the mixture of irregular fuel is present. On the other hand, if the engine exhaust temperature Te is 456 ° C. (step S19: Yes), it is considered that the irregular fuel has been mixed, and the process proceeds to step S22 as it is.

  Next, the control unit 132 controls the management source of the agricultural machine 110 (for example, the agricultural machine 110) corresponding to the identification information (specifically, model information and machine number information) in which the irregular fuel is detected by the mixing notification unit P5. The e-mail address of the rental company or service center to be managed) is specified, and there is a possibility that an irregular fuel is mixed in the management source to the agricultural machine 110 (specifically, the fuel tank 170) corresponding to the identification information. It is notified (for example, an e-mail is transmitted to the e-mail address of the rental company or service center that manages the agricultural machine 110) (step S20).

  Next, the control unit 132 uses the history storage unit P6 to indicate identification information for detecting the irregular fuel and information indicating that the irregular fuel has been detected in association with the management source corresponding to the identification information (in this example, irregular fuel). (Fuel detection date) is stored in the storage unit 134 (step S21).

  On the other hand, in step S18, the controller 132 selects the engine exhaust temperature Te received in step S10 by the irregular fuel mixture detection means P3 in step S16 as in the case of the second conversion table TB2 in step S19. In the first conversion table TB1, it is determined whether or not it is within the temperature range of the reference engine exhaust temperature Ts corresponding to the engine load factor R with respect to the engine speed C after the fuel supply timing determined by the fuel supply timing determination means P2. (Step S18) When the engine exhaust temperature Te is not within the temperature range of the reference engine exhaust temperature Ts (Step S18: No), it is assumed that there is an irregular fuel mixture, and the routine proceeds to Step S20, while the engine exhaust temperature. When the temperature Te is within the temperature range of the reference engine exhaust temperature Ts (step S18: Y s), control proceeds to step S22 is regarded as contamination irregular fuel come true.

  Next, the control part 132 repeats the process of step S10-S22 until there is an instruction | indication of a process end (step S22: No), and if there exists an instruction | indication of an operation end (step S22: Yes), a process operation will be complete | finished. .

It is configured to detect that irregular fuel is mixed in the agricultural machine 110 having an engine exhaust temperature Te that deviates from the tendency of the exhaust temperature Te. That is, the control unit 132 of the second embodiment is provided with a setting table TB3 instead of the first conversion table TB1 and the second conversion table TB2 of the storage unit 134 in the control unit 132 (see FIG. 7) of the first embodiment. In addition, instead of the irregular fuel mixture detection means P3 and the conversion table generation means P4 of the processing unit 133, the irregular fuel mixture detection means P3a and the engine exhaust temperature setting means P4a are provided.

  In addition, in the control part 132 of 2nd Embodiment, the same code | symbol is attached | subjected to the component of the same structure as the control part 132 of 1st Embodiment, and the description is abbreviate | omitted.

  The engine exhaust temperature setting means P4a is provided under the same conditions (for example, the engine load factor R with respect to the engine speed C for each temperature range of the outside air temperature To in the same model, specifically, the temperature of the outside air temperature To in the same region in the same model. The engine exhaust temperature Te corresponding to the engine load ratio R) with respect to the engine speed C for each range is sequentially stored in the setting table TB3 of the storage unit 134.

  Then, the irregular fuel mixture detection means P3a detects that the engine exhaust temperature Te received by the reception control means P1 is a tendency of the engine exhaust temperature Ta of the setting table TB3 set by the engine exhaust temperature setting means P4a (for example, in the setting table TB3). When the engine exhaust temperature corresponding to an engine load ratio of 40% to 50% with respect to the engine speed of 1200 rpm to 1400 rpm is set to a large number of temperatures such as 385 ° C., 386 ° C., 387 ° C., and 388 ° C.) The engine exhaust temperature Te received in this manner is a temperature within the temperature range (for example, 385 ° C. to 388 ° C.) of the engine exhaust temperature Ta set in the setting table TB3 or a predetermined temperature with respect to the temperature range (Eg 5 ° C) temperature that is only off In the case of a temperature such as 389 ° C. which is only 1 ° C. deviated from 388 ° C.), it is detected that regular fuel has been supplied to the fuel tank 170, and the engine exhaust temperature Ta set in the setting table TB3 is detected. If the temperature is outside the temperature range (for example, 385 ° C. to 388 ° C.) by a predetermined temperature (for example, 5 ° C.) or more (for example, a temperature of 395 ° C. that is 5 ° C. or more out of 388 ° C.) It is configured to detect that regular fuel is mixed. Note that the temperature range of the engine exhaust temperature Ta set in the setting table TB3 can be set after a predetermined time has elapsed (after the engine exhaust temperature Te received by the reception control means P1 has stabilized to some extent).
