On the other hand, the working device 2 is operated by the driving force of the prime mover 2 while the change control unit 34 sets the maximum output of the prime mover 4 to a changed maximum output (for example, 200 PS) that is increased from the standard maximum output. Can be made. Even if the standard maximum output of the prime mover 4 is 180 PS, the work device 2 can be operated with the driving force of the prime mover 4 with the maximum output temporarily increased to 200 PS.

Next, the configuration and operation in which the control device 30 changes the maximum output of the prime mover 4 according to the machine position will be described in detail.
The control device 30 includes a change position acquisition unit 35a and a change position setting unit 35b. The change position acquisition unit 35a and the change position setting unit 35b are configured by electric / electronic components provided in the control device 30, a program incorporated in the control device 30 and the like. The change position acquisition unit 35a acquires the output change position received by the communication apparatus 101 when the output change position is included in the change information received by the communication apparatus 101. The storage unit 32 of the control device 30 stores the output change position acquired by the change position acquisition unit 35a.

  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 machine position detected by the position detection device 41. . For example, when the ignition switch of the tractor 1 is set to ON, the change position setting unit 35b refers to the output change position stored in the storage unit 32. The change position setting unit 35b does not output a change command to the change acquisition unit 31 when the machine position detected by the position detection device 41 after the ignition switch is ON does not match the output change position referred to. In this case, the prime mover 4 is controlled by the standard control unit 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 coincides with the output change position, that is, when the tractor 1 enters the field A, the change position setting unit 35b changes the change command to the change acquisition unit. To 31. In this case, the control in the control device 30 is switched from the control by the standard control unit 33 to the control by the change control unit 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 as 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, the tractor 1 (working device 2) works at the standard maximum output in the field B, and the tractor 1 (working device 2) at the field A exceeds the standard maximum output. Work can be done with a high maximum output. In addition, when the tractor 1 is traveling on a farm road or road in a place other than the farm field, it can be driven at the standard maximum output.

Next, a configuration and operation in which the control device 30 changes the maximum output of the prime mover 4 with time will be described in detail.
The control device 30 includes a change time acquisition unit 36a and a change time setting unit 36b. The change time acquisition unit 36a and the change time setting unit 36b are configured by electric / electronic components provided in the control device 30, programs installed 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 command 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 (time measurement time). Output. For example, the change time setting unit 36b refers to the output change time stored in the storage unit 32 after the ignition switch of the tractor 1 is turned on. Since the change time setting unit 36b does not output a change command to the change acquisition unit 31 when the time of the time measuring unit 42 does not coincide with the referred output change time after the ignition switch is turned on, the motor 4 is not connected to the standard control unit 33. Is controlled based on the standard control map SCM. On the other hand, when the time of the timing unit 42 coincides with the output change time after the ignition switch is turned on, that is, from 8 o'clock on June 2 to 18:00 on June 2, the change time setting unit 36b changes the change command. It is output to the acquisition unit 31. For this reason, in the case of from 8:00 on June 2 to 18:00 on June 2, the prime mover 4 is controlled based on the change control map PCM.

  According to the second example described above, the maximum output of the prime mover 4 can be selectively used as the standard maximum output and the changed maximum output according to an arbitrary time of the tractor 1. Usually, when the situation where you want to use the tractor 1 (working device 2) at the standard maximum output and temporarily use the tractor 1 (working device 2) at the changed maximum output, time (output change time) By setting, it can be used at the changed maximum output.

Next, the configuration and operation in which the control device 30 changes the maximum output of the prime mover 4 by the work device 2 will be described in detail.
The control device 30 includes a change device acquisition unit 37a and a change device setting unit 37b. The change device acquisition unit 37a and the change device setting unit 37b are configured by electrical / electronic components provided in the control device 30, programs installed in the control device 30 and the like. When the change information received by the communication device 101 includes the device information, the change 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 change 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 device information (referred to as storage device information) stored in the storage unit 32. In addition, after the ignition switch of the tractor 1 is turned on, the changing device setting unit 37b requests device information (attaching device information) to the work device 2 connected to the connecting unit 8. When the storage device information indicates the mounting device information transmitted from the work device 2, the changing device setting unit 37b matches the name indicated by the storage device information and the name indicated by the attachment device information. If the model or model number indicated by the storage device information matches the model or model number indicated by the attachment device information, the identification information indicated by the storage device information and the identification indicated by the attachment device information When the information matches, the change command is output to the change acquisition unit 31 of the control device 30. That is, 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 attachment device information are associated (linked). In this way, when the storage device information and the attachment device information correspond, the prime mover 4 is controlled based on the change control map PCM.

  On the other hand, the change time setting unit 36b does not output a change command to the change acquisition unit 31 when the storage device information does not correspond to the attachment device information after the ignition switch is turned on. That is, the change time setting unit 36 b does not output a change command to the change acquisition unit 31 when the device information acquired by the change device acquisition unit 36 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 as the standard maximum output and the changed maximum output in accordance with the work device 2 connected to the tractor 1.
Next, the configuration and operation in which the control device 30 changes the maximum output of the prime mover 4 by the work device 2 will be described in detail.
As illustrated in FIG. 1, after the ignition switch of the tractor 1 is turned on, the control device 30 refers to the output information when the change information received by the communication device 101 includes the output information. When the maximum output indicated by the output information is the maximum output indicated by the change control map PCM, the control device 30 (change acquisition unit 31) switches the control of the prime mover 4 from the standard control map SCM to the change 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 output information (output of the prime mover) transmitted from the outside. According to this, the operator can set the maximum output of the prime mover 4 of the tractor 1 by simply setting the maximum output of the tractor 1 to be changed at the timing at which the operator wants to change and transmitting it to the tractor 1 arbitrarily. Can be changed.

  In the above-described embodiment, 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 are provided in the control device 30. 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 includes 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. It is not necessary to include all of the part 37b, and it is sufficient to provide at least one or a combination of a plurality of the above-described configurations.

  In the embodiment described above, the output change system of the work machine is a system that changes the maximum output of the prime mover 4, but it may not be the maximum output and may be a system that changes the output of the prime mover 4. For example, the standard control map SCM and the change control map PCM may be maps having the same maximum output but different output characteristics. In such a case, before changing the output of the prime mover 4, the control device 30 controls the prime mover 4 using the standard control map SCM having the same maximum output as the change control map PCM and different output characteristics. 4 is changed, the prime mover 4 is controlled using the change 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 the standard control map SCM and the change control map PCM having different output characteristics according to the change information.

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 the change information output from the external device 100. Therefore, a user who uses the tractor 1 or the like can change the output of the prime mover 1 of the tractor 1 simply by outputting the change information using the external device 100 different from the tractor 1.
The external device 100 has an output setting unit 113 that sets the output of the prime mover 4 as change information. For this reason, the user or the like can increase or decrease the output of the prime mover 4 simply by setting the output of the prime mover 4 using the external device 110.

For this reason, the user or the like uses the external device 100 to set an output change position (location) where the output of the prime mover 4 is to be increased and an output change position where the output of the prime mover 4 is reduced, so that the output change position can be changed. The output of the prime mover 4 can be arbitrarily changed.

  The work machine output change system includes a timer 41, and the external device 100 includes a time setting unit 111 that sets an output change time. 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 time measuring unit 41 coincides with the output change time. For this reason, the user or the like uses the external device 100 to arbitrarily set the output change time for increasing the output of the prime mover 4 and the output change time for reducing the output of the prime mover 4 according to the output change time. The output of the prime mover 4 can be changed.

  The work machine output change system includes a work device 2, and the external device 100 includes a device setting unit 112 that sets device information. 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 in the tractor 1. For this reason, by setting the working device 2 that the user or the like wants to work by increasing the output of the prime mover 4 and the working device 2 that wants to work by reducing the output of the prime mover 4 by using the external device 100, 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 have to include all of the position setting unit 110, the time setting unit 111, the device setting unit 112, and the output setting unit 113. You just have to prepare.

Can also be set. The mobile terminal can transmit the changed information (output change location, output change time, device information, output information, etc.) after setting to the communication device 101.

Further, the external device 100 may be only the management computer, and it is preferable to provide any one of the position setting unit 110, the time setting unit 111, the device setting unit 112, and the output setting unit 113 in the management computer. The management computer can transmit post-setting change information (output change location, output change time, device information, output information, etc.) to the communication device 101.
Further, the external device 100 may be configured by arbitrarily combining a portable 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 unit 110, the time setting unit 111, the device setting unit 112, and the output setting unit 113 in any of the portable terminal, the management computer, and the server.

FIG. 5 shows an output change system for a work machine in the second embodiment. In the second embodiment, a configuration different from the first embodiment will be described.

Prior to changing the output of the prime mover 4, the work machine output changing system notifies the operator, etc., operating the tractor 1 of the expense, and the operator confirms (acknowledges) the expense notification. It is a system that can change the maximum output in the case of.
The tractor 1 includes a display device 50. The display device 50 is a device that displays various types of information, and includes a liquid crystal panel or the like. The display device 50 displays the cost generated by changing the output of the prime mover 4. When changing the maximum output of the prime mover 4 (when the machine position coincides with the output change position, when the timekeeping time coincides with the output change time, or when the work device indicates the device information), as shown in FIG. In addition, the display device 50 displays the confirmation screen M5 on which the cost generated by the output change is displayed, and displays the cost on the cost display unit 81 assigned to the confirmation screen M5. When the confirmation member [button that confirms (acknowledges that costs have been generated)] 57 displayed on the confirmation screen M5 is selected, the control device 30 changes the output of the motor 4, for example, the standard maximum output Change from maximum to maximum output. The display device 50 may display the maximum output scheduled to be changed on the output display unit 82 assigned to the confirmation screen M5.

  The cost is between the tractor 1 user side (operator, operator, manager, company, etc.) and the tractor 1 provider side (tractor service company, tractor rental company, tractor manufacturing company, etc.) It is for conducting a financial transaction (financial transaction) to be paid, and is a currency or a point set in advance by a service. When the changed maximum output is increased with respect to the standard maximum output (V1 <V2), the cost on the user side (cost displayed on the tractor 1) is indicated by plus. On the other hand, when the changed maximum output is decreased with respect to the standard maximum output (V1> V2), the cost on the user side is indicated by minus.

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, each time the changed maximum output is increased by 1 PS with respect to the standard maximum output, the cost paid by the user is increased, and the changed maximum output is increased by 1 PS with respect to the standard maximum output. The method for setting the cost is not limited to the method described above.
As shown in FIG. 6, when the confirmation member 57 on the confirmation screen M5 is selected and the user accepts the expense, the server 100a or the like performs the process for the expense.

The identification information of the tractor 1 is the name, model, machine number, manufacturing number, etc. of the tractor 1, and unique information unique to the tractor 1 is assigned thereto. The user identification information includes the user name, address, telephone number, e-mail address, and the like. The association between the identification information of the tractor 1 and the identification information of the user is performed 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 includes 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 on the user associated with the tractor 1 whose output has been changed. The financial processing unit 71 specifies a user (user identification information) associated with the tractor 1 from the identification information of the tractor 1 as financial processing, and generates information (cost information) about the cost for the user. When the user charges the user from the user side, the financial processing unit 71 generates user billing data as the cost information, performs a predetermined process with a server such as a financial institution, and then asks the financial institution. Send billing data. The financial institution performs a billing process on the user based on the billing data transmitted from the financial processing unit 71, and then, the user pays the cost paid by the user to the user side. .

  On the other hand, the financial processing unit 71 generates payment data of the user as cost information when paying a cost from the user side to the user, and after performing predetermined processing with a server such as a financial institution, Send payment data to the institution. Based on the payment data transmitted from the financial processing unit 71, the financial institution executes payment of expenses to a predetermined account of the user. The processing of the financial processing unit 71 is an example and is not limited to the method described above.

  In addition, you may display expense etc. using the management software etc. which manage work. In this case, as illustrated in FIG. 5, the server 100 a includes a cost management unit 115 and a machine database (DB) 116. The cost management unit 115 is composed of electrical / electronic components provided in the server 100a, programs incorporated in the server 100a, and the like. The expense management unit 115 displays at least an expense when setting a work plan or the like in work using a tractor or the like. As shown in FIG. 8, the machine database 116 stores the relationship between the identification information for identifying the tractor 1, the output of the tractor 1 (standard maximum output, changed 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. 9, the expense management unit 115 sets a work plan in the management computer 100b. Is displayed. The setting screen M10 includes an agricultural field setting unit 121 that sets an agricultural field, a time setting unit 122 that sets time, a work setting unit 123 that sets work, and a machine setting unit 124 that sets a machine. The farm field setting unit 121 sets a farm field name, a farm area, and the like on which work is performed. In the date setting unit 122, a time (date or the like) for performing work is set. The operation setting unit 123 sets operations such as tillage, fertilizer application, drug application, mowing, and harvesting. The machine setting unit 124 sets machine information (name, model, number, serial number, etc.) of a tractor used for work, and device information (name, model, number, etc.) of a work device connected to the tractor. Setting (input) in the field setting unit 121, the time setting unit 122, and the machine setting unit 124 can be performed by an input interface (keyboard, mouse, or the like) of the management computer 100b.

  The setting screen M10 includes a guidance display unit 125. The guidance display unit 125 displays guidance when the maximum output of the tractor is changed from the standard maximum output to the changed maximum output in the tractor set by the machine setting unit 124. 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 (advantage) when the work indicated in the work plan is changed from the standard maximum output to the changed maximum output. .

For example, the cost management unit 115 identifies the tractor 1 based on the machine information set by the machine setting unit 124, and then refers to the machine database 116 to thereby calculate the cost corresponding to the identified maximum output of the tractor 1. Extract. Then, the cost management unit 115 displays the extracted cost and the change maximum output on the guidance display unit 125.
Further, the expense management unit 115 calculates an evaluation value when the work indicated in the work plan is changed from the standard maximum output to the changed maximum output by using various evaluation parameters such as work and machine. For example, when the evaluation parameter is “days”, the expense management unit 115 calculates, as an evaluation value, the difference between the normal days when working with the standard maximum output and the special days when working with the changed maximum output as the evaluation value. . The expense management unit 115 sets the number of days when working with the standard maximum output to the normal number of days indicated by the date setting unit 122. The cost management unit 115 obtains a ratio (standard maximum output / change maximum output) obtained by dividing the standard maximum output by the change maximum output, and calculates the special days by adding the ratio to the normal days [special days = normal days × ratio (Standard maximum output / change maximum output)], and the difference in days is obtained by dividing the special days and the normal days. The special days, the difference between the normal days and the special days, etc. are not limited to the method described above. In the cost management unit 115, the evaluation parameter is not limited to the number of days, and may be labor cost such as fuel consumption and labor cost, or may be other.

The cost management unit 115 displays the calculated evaluation value on the guidance display unit 125. For example, when the evaluation value is a difference in days as described above, the expense management unit 115 displays the guidance display unit 125 as follows: “If the maximum output is changed from 180 PS to 200 PS and the work is performed, the number of days can be shortened by D1 days. Is displayed.
In the above-described embodiment, the cost is calculated as money. Instead, it may be replaced with a point (service point) set by the provider. When the user pays the cost to the provider, the service point assigned to the user is subtracted, and when the provider pays the cost to the user, the service point assigned to the user is added. When the service point reaches a predetermined level or more, the user pays the service point to the provider, so that the service provided by the provider (part replacement, repair, work machine maintenance, etc.) can be received.
[Third Embodiment]
FIG. 10 shows an output change system for a work machine according to the third embodiment. In the third embodiment, a configuration different from the first embodiment or the third embodiment will be described.

As illustrated 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 at the time of rental or purchase of the tractor 1, the server 100 a transmits the storage authentication information to the tractor 1 (communication device 101) and stores the storage authentication information in the storage unit 32. On the other hand, the user gives the user a key device 73 that is one of external devices that store 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 the ignition switch, and is a start key, an IC card, a portable terminal, or the like.

  When the key device 73 is a start key, the start key can be inserted into a key cylinder 74 provided in the tractor 1. When the start key is inserted into the key cylinder 74, the external authentication information is transmitted to the control device 30 via the key cylinder 74. The control device 30 turns the ignition switch from OFF to ON after the authentication between the external authentication information and the stored authentication information is established. The control device 30 switches the change in 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 in the prime mover 4 when the authentication is established.

  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 in 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 in the output of the prime mover 4 from invalid to valid.

  When the key device 73 is a mobile terminal, the mobile terminal transmits external authentication information to the communication device 101 provided in the tractor 1 at the start of starting of the prime mover 4. The communication apparatus 101 transmits the acquired external authentication information to the control apparatus 30 after acquiring the external authentication information. 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 in the output of the prime mover 4 from invalid to valid. The above-described configuration of the external device 100 may be provided in the key device 73 (external device).

Therefore, the control device 30 authenticates the storage authentication information and the external authentication information, and permits the change of the output in the prime mover 4 when the authentication is established. 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 by an unauthorized means by enabling the change of the output of the prime mover 4 after the authentication is established. Can be suppressed.
The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

  In the above-described embodiment, the output of the prime mover 4 is changed by 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, in the case of an operator, when an operator associated with the tractor 1 gets on, the control device 30 changes the output of the prime mover 4, for example, the standard maximum output to the changed maximum output. The operator is detected by determining whether or not the operator is associated with the tractor 1 by an imaging device such as a camera provided in the tractor 1, fingerprint authentication, or the like.

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