The change position setting unit 35b outputs a change command to the change acquisition unit 31 of the control device 30 when the output change position acquired by the change position acquisition unit 35a matches the mechanical position detected by the position detection device 41. . For example, when the ignition switch of the tractor 1 is turned on, the change position setting section 35b refers to the output change position stored in the storage section 32. FIG. The change position setting unit 35b does not output a change command to the change acquisition unit 31 when the mechanical position detected by the position detection device 41 after the ignition switch is turned on does not match the output change position referred to. In this case, the prime mover 4 is controlled by the standard control section 33 based on the standard control map SCM. On the other hand, when the machine position detected by the position detection device 41 after the ignition switch is turned on matches the output change position, that is, when the tractor 1 enters the field A, the change position setting unit 35b sends a change command to the change acquisition unit. 31. In this case, the control in the control device 30 is switched from the control by the standard control section 33 to the control by the change control section 34, and the prime mover 4 is controlled based on the change control map PCM.

According to the first example described above, the maximum output of the prime mover 4 can be selectively used between the standard maximum output and the changed maximum output according to the mechanical position of the tractor 1 . For example, when working across a plurality of fields, in field B, tractor 1 (work device 2) works at the standard maximum output, and in field A, tractor 1 (work device 2) works at the standard maximum output. Work can be done at high modified maximum power. Further, when the tractor 1 is self-propelled on farm roads and roads other than agricultural fields, the tractor 1 can be driven at the standard maximum output.

Next, the configuration and operation of the controller 30 changing the maximum output of the prime mover 4 with time will be described in detail.
The control device 30 has a change time acquisition section 36a and a change time setting section 36b. The change time acquisition unit 36a and the change time setting unit 36b are composed of electric/electronic components provided in the control device 30, programs incorporated in the control device 30 and the like. When the change information received by the communication device 101 includes the output change time, the change time acquisition unit 36a acquires the output change time received by the communication device 101 . The storage unit 32 of the control device 30 stores the output change time acquired by the change time acquisition unit 36a.

The change time setting unit 36b issues a change instruction to the change acquisition unit 31 of the control device 30 when the output change time acquired by the change time acquisition unit 36a matches the time measured by the time measurement unit 42 (measured time). Output. For example, after the ignition switch of the tractor 1 is turned on, the change time setting unit 36b refers to the output change time stored in the storage unit 32. FIG. The change time setting unit 36b does not output a change command to the change acquisition unit 31 if the time of the clock unit 42 does not match the output change time referred to after the ignition switch is turned on. based on the standard control map SCM. On the other hand, when the time of the clock unit 42 matches the output change time after the ignition switch is turned on, that is, from 8:00 on June 2nd to 18:00 on June 2nd, the change time setting unit 36b changes the change command. It is output to the acquisition unit 31 . Therefore, from 8:00 on June 2nd to 18:00 on June 2nd, the prime mover 4 is controlled based on the modified control map PCM.

According to the second example described above, the maximum output of the prime mover 4 can be selectively used between the standard maximum output and the changed maximum output according to the arbitrary time of the tractor 1 . Normally, the tractor 1 (working device 2) is used at the standard maximum output, and if a situation arises where you want to temporarily use the tractor 1 (working device 2) at the changed maximum output, the time (output change time) can be used with a modified maximum output by setting

Next, the configuration and operation of the control device 30 changing the maximum output of the prime mover 4 by the work device 2 will be described in detail.
The control device 30 has a changing device acquiring section 37a and a changing device setting section 37b. The changing device acquisition unit 37a and the changing device setting unit 37b are composed of electrical/electronic components provided in the control device 30, programs incorporated in the control device 30, and the like. When the change information received by the communication device 101 includes the device information, the changed device acquisition unit 37a acquires the device information received by the communication device 101 . The storage unit 32 of the control device 30 stores the device information acquired by the changed device acquisition unit 37a.

The change device setting unit 37b outputs a change command to the change acquisition unit 31 of the control device 30 when the device information acquired by the change device acquisition unit 37a indicates the work device 2 connected to the connection unit 8. . For example, after the ignition switch of the tractor 1 is turned on, the changing device setting unit 37b refers to the device information stored in the storage unit 32 (referred to as storage device information). Further, after the ignition switch of the tractor 1 is turned on, the changing device setting section 37b requests the working device 2 connected to the connecting portion 8 for device information (mounting device information). When the storage device information indicates the mounting device information transmitted from the work device 2 (the name indicated by the storage device information and the name indicated by the mounting device information match), the changing device setting unit 37b If the model or model number indicated in the storage device information and the model or model number indicated in the mounting device information match, the identification information indicated in the storage device information and the identification indicated in the mounting device information information matches), a change command is output to the change acquisition unit 31 of the control device 30 . In other words, the change device setting unit 37b outputs a change command to the change acquisition unit 31 of the control device 30 when the storage device information and the mounting device information correspond (are linked). In this way, when the storage device information and the mounting device information correspond, the prime mover 4 is controlled based on the change control map PCM.

On the other hand, the change device setting unit 37b does not output a change command to the change acquisition unit 31 when the storage device information and the mounting device information do not correspond after the ignition switch is turned on. That is, the changing device setting unit 3 7 b does not output a change command to the change acquiring unit 31 when the device information acquired by the changing device acquiring unit 3 7 a does not indicate the work device 2 . In this case, the prime mover 4 is controlled based on the standard control map SCM.

According to the third example described above, the maximum output of the prime mover 4 can be selectively used between the standard maximum output and the changed maximum output according to the working device 2 connected to the tractor 1 .
Next, the configuration and operation of the control device 30 changing the maximum output of the prime mover 4 by the work device 2 will be described in detail.
As shown in FIG. 1, after the ignition switch of the tractor 1 is turned on, if the change information received by the communication device 101 includes output information, the control device 30 refers to the output information. When the maximum output indicated by the output information is the maximum output indicated by the modified control map PCM, the control device 30 (modified control map PCM) switches the control of the prime mover 4 from the standard control map SCM to the modified control map PCM, Control is performed based on the change control map PCM.

According to the fourth example described above, the prime mover 4 can change the maximum output of the prime mover 4 based on the output information (output of the prime mover) transmitted from the outside. According to this, the operator can arbitrarily set the maximum output of the tractor 1 at the timing desired to be changed by the external device 100 and transmit the maximum output to the tractor 1 to change the maximum output of the prime mover 4 of the tractor 1. can be changed.

In the above-described embodiment, the control device 30 is provided with the change position acquisition unit 35a, the change position setting unit 35b, the change time acquisition unit 36a, the change time setting unit 36b, the change device acquisition unit 37a, and the change device setting unit 37b. However, at least one or all of these may be provided in the display device 50 . As described in the first to fourth examples, the tractor 1 has the changed position acquisition unit 35a,
It is not necessary to include all of the change position setting unit 35b, the change time acquisition unit 36a, the change time setting unit 36b, the change device acquisition unit 37a, and the change device setting unit 37b. It suffices to have a configuration in which

In the above-described embodiment, the system for changing the output of the working machine is a system for changing the maximum output of the prime mover 4 , but it may be a system for changing the output of the prime mover 4 instead of the maximum output. For example, the standard control map SCM and the modified control map PCM may have the same maximum output but different output characteristics. In such a case, the control device 30 controls the prime mover 4 using the standard control map SCM having the same maximum output as the modified control map PCM and having different output characteristics before changing the output of the prime mover 4. 4, the motor 4 is controlled using a modified control map PCM having the same maximum output as the standard control map SCM and different output characteristics. That is, the output of the prime mover 4 can be changed by switching between the standard control map SCM and the modified control map PCM, which have different output characteristics, according to modification information and the like.

The work machine output change system includes a control device 30 and an external device 100 , and the control device 30 changes the output of the prime mover 4 based on change information output from the external device 100 . Therefore, the output of the prime mover 4 of the tractor 1 can be changed simply by outputting the change information using the external device 100 different from the tractor 1 by the user or the like using the tractor 1 or the like.
The external device 100 has an output setting section 113 that sets the output of the prime mover 4 as change information.

The work machine output change system includes a clock unit 42 , and the external device 100 has a time setting unit 111 for setting the output change time. In addition, the external device 100 outputs the output change time as change information. The control device 30 changes the output of the prime mover 4 when the time measured by the timer 42 matches the output change time. Therefore, the user or the like uses the external device 100 to set the output change time for which the output of the prime mover 4 is desired to be increased and the output change time for which the output of the prime mover 4 is decreased. The output of the prime mover 4 can be changed.

The work machine output changing system includes the work device 2, and the external device 100 has a device setting section 112 for setting device information. In addition, the external device 100 outputs the device information of the work device 2 as change information. The control device 30 changes the output of the prime mover 4 when the device information indicates the work device 2 provided on the tractor 1 . For this reason, a user or the like uses the external device 100 to set the work device 2 that is desired to work with the output of the prime mover 4 increased and the work device 2 that is desired to work with the output of the prime mover 4 decreased. The output of the prime mover 4 can be arbitrarily changed according to the work device 2 attached to the tractor 1 .

Note that the external device 100 does not need to include all of the position setting section 110, the time setting section 111, the device setting section 112, and the output setting section 113, and may include at least one of the above-described configurations, or a combination of a plurality of configurations. Be prepared.
Also, the external device 100 may be a mobile terminal, and it is preferable that the mobile terminal be provided with one of the position setting section 110 , the time setting section 111 , the device setting section 112 and the output setting section 113 . In this case, by carrying the mobile terminal when performing work, the user can change the change information (output change location, output change time, device information, output information, etc.) before, during, or after work. can also be set. The mobile terminal can transmit change information (output change location, output change time, device information, output information, etc.) after setting to the communication device 101 .

Also, the external device 100 may be only a management computer, and it is preferable that the management computer be provided with one of the position setting section 110, the time setting section 111, the device setting section 112, and the output setting section 113. The management computer can transmit change information (output change location, output change time, device information, output information, etc.) after setting to the communication device 101 .
Also, the external device 100 may be an arbitrary combination of a mobile terminal, a management computer, an electronic storage medium, and a server. In this case, it is preferable to provide any one of the position setting section 110, the time setting section 111, the device setting section 112, and the output setting section 113 in any one of the mobile terminal, the management computer, and the server.

[Second embodiment]
FIG. 5 shows a work machine output change system according to the second embodiment. In the second embodiment, a configuration different from that of the first embodiment will be described.

The work machine output change system notifies the operator or the like who drives the tractor 1 of the cost before changing the output of the prime mover 4, and the operator confirms (approves) the notification of the cost. It is a system that can change the maximum output when
The tractor 1 has a display device 50 . The display device 50 is a device for displaying various information, and is composed of a liquid crystal panel or the like. The display device 50 displays the costs incurred by changing the output of the prime mover 4 . When changing the maximum output of the prime mover 4 (when the machine position matches the output change position, when the clock time matches the output change time, when the work device indicates device information), as shown in FIG. Then, the display device 50 displays a confirmation screen M5 showing the costs incurred by changing the output, and displays the costs on the cost display section 81 assigned to the confirmation screen M5. When the confirmation member [button indicating confirmation (approval) that costs are incurred] 57 displayed on the confirmation screen M5 is selected, the control device 30 changes the output of the prime mover 4, for example, the standard maximum output Change from to change maximum output. The display device 50 may display the maximum output to be changed on the output display section 82 assigned to the confirmation screen M5.

The cost is between the user side of the tractor 1 (operator, worker, manager, company, etc.) and the provider side of the tractor 1 (tractor service company, tractor rental company, tractor manufacturing company, etc.) It is used to perform a monetary transaction (financial transaction) to be paid, and is money or points set in advance in the service. Also, when the modified maximum output is increased with respect to the standard maximum output (V1<V2), the cost on the user side (the cost displayed on the tractor 1) is indicated by plus. On the other hand, if the modified maximum power is decreased with respect to the standard maximum power (V1>V2), the cost to the user is shown as a minus.

Note that the relationship between the changed maximum output after the change and the cost is stored in the control device 30, the display device 50, and the like. For example, the cost paid by the user is increased for each 1 PS increase of the modified maximum output with respect to the standard maximum output, and the cost paid by the provider is increased for each 1 PS modified maximum output with respect to the standard maximum output. The cost setting method and the like are not limited to the methods described above.
As shown in FIG. 6, when the confirmation member 57 of the confirmation screen M5 is selected and the user approves the payment, the server 100a or the like processes the payment.

As shown in FIG. 5, the server 100a includes a financial processing unit 71 and a user database (DB) 72. As shown in FIG. 7, the user database 72 stores the identification information of the tractor 1 (machine identification information) and the identification information of the user (user identification information) in association with each other. The identification information of the tractor 1 is the name, model, serial number, manufacturing number, etc. of the tractor 1, and unique information specific to the tractor 1 is assigned. The user's identification information is the user's name, address, telephone number, e-mail address, etc., and is assigned unique information of the user. The identification information of the tractor 1 and the identification information of the user are associated with each other when the user uses the tractor 1, such as when the tractor 1 is purchased or when the tractor 1 is rented.

The financial processing unit 71 is composed of electrical/electronic components provided in the server 100a, programs installed in the server 100a, and the like. The financial processing unit 71 performs financial processing related to finance for the user associated with the tractor 1 whose output has been changed. As financial processing, the financial processing unit 71 identifies a user (user identification information) associated with the tractor 1 from the identification information of the tractor 1, and generates cost information (cost information) for the user. When the user charges the user, the financial processing unit 71 generates billing data for the user as cost information, performs predetermined processing with the server of the financial institution, etc., and then sends the data to the financial institution. Submit billing data. Based on the billing data sent from the financial processing unit 71, the financial institution charges the user for the expenses, and then transfers the expenses paid by the user to the user. .

On the other hand, when the user pays the user, the financial processing unit 71 generates payment data of the user as the cost information, performs predetermined processing with a server of a financial institution, etc., and then processes the data. Send payment data to the institution. Based on the payment data transmitted from the financial processing unit 71, the financial institution deposits the fee into the user's predetermined account. Note that the processing of the financial processing unit 71 is an example, and is not limited to the method described above.

The cost may be displayed using management software or the like for managing work. In this case, as shown in FIG. 5, the server 100a includes a cost management unit 115 and a machine database (DB) 116. The expense management unit 115 is composed of electric/electronic components provided in the server 100a, programs installed in the server 100a, and the like. The cost management unit 115 displays at least the cost when setting a work plan or the like for work using a tractor or the like. As shown in FIG. 8, the machine database 116 stores identification information for identifying the tractor 1, the relationship between the output of the tractor 1 (standard maximum output, modified maximum output), and cost.

Specifically, when the management computer 100b logs in to the server 100a and performs a predetermined operation, as shown in FIG. display. The setting screen M10 has a field setting portion 121 for setting a field, a date setting portion 122 for setting time, a work setting portion 123 for setting work, and a machine setting portion 124 for setting a machine. The field setting unit 121 sets field names, field areas, and the like in which work is to be performed. The date setting section 122 sets the time (date, etc.) for performing the work. The work setting unit 123 sets work such as plowing, fertilizer application, chemical application, mowing, and harvesting. The machine setting unit 124 sets machine information (name, model, serial number, manufacturing number, etc.) of the tractor used for the work, and device information (name, model, serial number, etc.) of the working device connected to the tractor. Settings (inputs) in the field setting unit 121, the date setting unit 122, and the machine setting unit 124 can be performed using an input interface (keyboard, mouse, etc.) of the management computer 100b.

Further, the setting screen M10 has a guidance display section 125. As shown in FIG. The guidance display section 125 displays guidance when the maximum output of the tractor set by the machine setting section 124 is changed from the standard maximum output to the changed maximum output. For example, the guidance display unit 125 displays the cost when changing from the standard maximum output to the changed maximum output and the merit (benefit) when changing the work indicated in the work plan from the standard maximum output to the changed maximum output. .

For example, after specifying the tractor 1 based on the machine information set by the machine setting unit 124, the cost management unit 115 refers to the machine database 116 to calculate the cost corresponding to the changed maximum output of the specified tractor 1. Extract. The cost management unit 115 then displays the extracted cost and changed maximum output on the guidance display unit 125 .
The expense management unit 115 also uses various evaluation parameters such as work and machine to calculate an evaluation value when the work indicated in the work plan is changed from the standard maximum output to the modified maximum output.
For example, if the evaluation parameter is "number of days", the expense management unit 115 calculates the difference in days between the normal number of days when working with the standard maximum output and the special number of days when working with the changed maximum output as the evaluation value. . The expense management unit 115 sets the normal number of days indicated by the date setting unit 122 to the number of days when working with the standard maximum output. The expense management unit 115 calculates the ratio (standard maximum output/changed maximum output) by dividing the standard maximum output by the changed maximum output, and calculates the special days by multiplying the normal days by the ratio [special days = normal days × ratio (standard maximum output/changed maximum output)], and the difference in days is obtained by calculating the difference between the special days and the normal days. Note that the special number of days, the difference between the normal number of days and the special number of days, and the like are not limited to the methods described above. In addition, the evaluation parameter of the cost management unit 115 is not limited to the number of days, and may be labor costs such as fuel consumption and personnel costs, or may be other parameters without limitation.

Expense management unit 115 displays the calculated evaluation value on guidance display unit 125 . For example, when the evaluation value is the number of days difference as described above, the expense management unit 115 displays the guidance display unit 125 as follows: "If you change the maximum output from 180PS to 200PS and work, the number of days can be shortened by D1 days. is displayed.
In the above-described embodiment, the cost is calculated as money, but instead of this, points (service points) set by the provider may be used. When the user side pays the cost to the provider, the service points assigned to the user are subtracted, and when the provider pays the cost to the user, the service points assigned to the user are added. When the service points exceed a predetermined value, the user can receive services (part replacement, repair, work machine maintenance, etc.) provided by the provider by paying service points to the provider.
[Third Embodiment]
FIG. 10 shows a working machine output changing system according to the third embodiment. 3rd Embodiment demonstrates the structure different from 1st Embodiment or 2nd Embodiment.

As shown in FIG. 10, the server 100a transmits authentication information (stored authentication information) to the tractor 1 (communication device 101). When the communication device 101 receives the authentication information, the received authentication information is stored in the storage unit 32 of the control device 30 .
For example, when performing user registration when renting or purchasing the tractor 1 , the server 100 a transmits the stored authentication information to the tractor 1 (communication device 101 ) and stores the stored authentication information in the storage unit 32 . On the other hand, the user gives the user the key device 73, which is one of the external devices that stores authentication information (external authentication information) corresponding to the stored authentication information notified by the server 100a. The key device 73 is a device for turning on an ignition switch, and is a start key, an IC card, a portable terminal, or the like.

If the key device 73 is a starting key, the starting key can be inserted into a key cylinder 74 provided on the tractor 1 . The start key transmits external authentication information to the control device 30 via the key cylinder 74 when inserted into the key cylinder 74 . The control device 30 turns the ignition switch from OFF to ON after the authentication of the external authentication information and the stored authentication information is established. The control device 30 switches the change of the output of the prime mover 4 from invalid to valid after authentication by the authentication information is established when the prime mover 4 is started. That is, the control device 30 authenticates the stored authentication information and the external authentication information, and permits the change of the output of the prime mover 4 when the authentication is successful.

Further, when the key device 73 is an IC card, the IC card can output external authentication information to a reading device (reader device) 75 provided on the tractor 1 . After acquiring the external authentication information, the reading device 75 transmits the acquired external authentication information to the control device 30 . As with the start key, when the authentication information is established, the control device 30 turns the ignition switch from OFF to ON and switches the change of the output of the motor 4 from invalid to valid.

If the key device 73 is a mobile terminal, the mobile terminal transmits the external authentication information to the communication device 101 provided on the tractor 1 when starting the engine 4 starts. After acquiring the external authentication information, the communication device 101 transmits the acquired external authentication information to the control device 30 . As with the start key, when the authentication information is established, the control device 30 turns the ignition switch from OFF to ON and switches the change of the output of the motor 4 from invalid to valid. The configuration shown in the external device 100 may be provided in the key device 73 (external device) described above.

Therefore, the control device 30 authenticates the stored authentication information and the external authentication information, and permits the change of the output of the prime mover 4 when the authentication is successful. In this way, the authentication information is authenticated when the prime mover 4 is started, and the output of the prime mover 4 can be changed after the authentication is established, thereby preventing the output of the prime mover 4 from being changed by illegal means. can be suppressed.
It should be considered that the embodiments disclosed this time are illustrative in all respects and not restrictive. The scope of the present invention is indicated by the scope of the claims rather than the above description, and is intended to include all modifications within the scope and meaning equivalent to the scope of the claims.

In the above-described embodiment, the output of the prime mover 4 is changed according to time (output change time), position (output change position), device (device information), and output information. The output of the prime mover 4 may be changed. For example, if an operator, the controller 30 changes the power output of the prime mover 4, eg, standard maximum power, to a modified maximum power when the operator associated with the tractor 1 enters. For the detection of the operator, whether or not the operator is tied to the tractor 1 is determined by an imaging device such as a camera provided on the tractor 1, fingerprint authentication, or the like.

In addition, when the external device 100 such as a server transmits the output change time, the output change position, the device information, and the output information to the tractor 1 (communication device 101), the data of the change control map PCM having the maximum output or the setting parameter may be sent. In this case, the control device 30 transfers the change control map PCM to the storage unit 32 after the communication device 101 receives it, and stores it temporarily. Further, the control device 30 deletes the change control map PCM stored in the storage unit 32 after the change of the maximum output is completed. In this way, the maximum output and the like can be changed even if the change control map PCM is not stored in the storage unit 32 of the control device 30 in advance. In addition, since the change control map PCM is stored in the storage unit 32 only when changing the maximum output, it is possible to prevent unauthorized change of the maximum output and improve security.
