Description

  The present invention relates to a work machine such as a tractor and a backhoe, and a payment system for the work machine.

Conventionally, work machines such as tractors and backhoes are manufactured by a manufacturing company (manufacturer), and the manufactured work machines are delivered to a store (dealer) consigned for sale by the manufacturing company to customers at the store. Sold. Payment of the price of the work machine sold is often made through a financial company, and payment may be made in installments.
Here, if there is no restriction on the operation of the work equipment for which payment has not been completed, it is possible to continue using the work equipment without paying the price even if the payment due date has passed. it can. In order to prevent such a situation, a technique has been developed that restricts the operation (operation) of a work machine when payment is not made when the due date of the work machine arrives (for example, Patent Documents). 1).

  In Patent Document 1, the payment date set at the time of the purchase contract of the work machine is stored in the work machine, and it is determined whether or not the current date has passed the payment date stored in the work machine when the work machine is started. The operation machine is disabled by the operation stop unit only when it is determined by the means and it is determined that the current time has passed the due date.

[First embodiment]
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows an overall view of a price payment management system for a work machine.
The work machine price payment management system 1 includes a payment management server 3 that manages the price payment status of the work machine 2, a wireless terminal 4 provided in the work machine 2, and a control device 5 provided in the work machine 2. I have.

  In the work machine price payment management system 1, when the work machine 2 is paid for, a signal (permission signal) S for payment from the payment management server 3 via the network N is sent to the wireless terminal 4 of the work machine 2. And when the wireless terminal 4 receives the permission signal S, the use of the work machine 2 is extended. On the other hand, when the work machine 2 is not paid, the permission signal S is transmitted to the work machine 2. The use of the work machine 2 is not extended.

First, the working machine 2 will be described in detail.
FIG. 8 shows a tractor that is an example of the work machine 2.
As shown in FIG. 8, the tractor 2 is configured by mounting an engine (for example, a diesel engine) 11, a transmission device 12, and the like on a traveling vehicle body 10 having front and rear wheels. A three-point link mechanism 16 is provided at the rear portion of the traveling vehicle body 10 so as to be movable up and down. Various working devices (in the illustrated example, a tilling device) 13 are detachably attached to the three-point link mechanism 16. Power from the engine 11 is transmitted to the work device 13 via the PTO shaft. In addition, an independently mounted cabin 14 is provided behind the engine 11, and a driver seat 15 is provided in the cabin 14. The tractor 22 is configured to be able to run and work by the working device 13.

  FIG. 2 shows the control device 5. The control device 5 controls the traveling system and the working system in the tractor 2 and is composed of a CPU and the like. In the tractor 2, the control of the traveling system and the control of the work system are performed by a plurality of (for example, two) control devices 5 (5A, 5B). In this embodiment, the tractor 2 is controlled by the plurality of control devices 5A and 5B. However, the number of the control devices 5 may be one or more, and is not limited to the following.

The first control device 5A controls the entire tractor 2, and can perform mutual communication with another control device 5B, that is, the second control device 5B.
The first control device 5A is inputted with an operation amount of the accelerator pedal when the accelerator pedal is operated, a shift lever position when the shift lever for shifting is operated, and the like.

  The first control device 5A outputs a control command to the second control device 5B so that the engine 11 reaches a predetermined rotational speed based on the operation amount of the accelerator pedal, and controls the transmission device 12 based on the shift lever position. (Shift control) can be performed. In addition, the engine control upper limit value, the accelerator lever amount, the engine speed, and the like are input to the first control device 5A. The engine rotation upper limit value can be set by a volume provided in the vicinity of the driver seat 15, and the accelerator lever amount can be set by an accelerator lever provided in the vicinity of the driver seat 15.

  When the engine rotation upper limit value is input, the first control device 5A outputs a control command to the second control device 5B so that the rotation speed of the engine 11 does not exceed the engine rotation upper limit value. When the accelerator lever amount is input, the first control device 5A sends a control command corresponding to the accelerator pedal operation amount to the second control device 5B if the accelerator pedal operation amount is equal to or greater than the accelerator lever amount. However, when the operation amount of the accelerator pedal is less than the accelerator lever amount, the control command according to the operation amount of the accelerator pedal is not performed, and the rotation speed of the engine 11 is not controlled according to the operation amount of the accelerator pedal. It has become.

Further, the first control device 5A controls the display device 24 that displays various information of the tractor 2 such as the engine speed, the shift speed, the oil temperature, and the like, and based on the input from the operation member, the three-point link mechanism 16 Elevation is controlled (3P elevation control).
The second control device 5B (engine computer unit) mainly controls the engine 11, and is used to input the operation amount of the accelerator pedal, the crank position, the cam position, etc. output via the first control device 5A. Based on this, the injector 27, common rail 28, supply pump 29 and the like are controlled. A signal indicating ON or OFF of the ignition switch 30 is input to the second control device 5B. When the on signal of the ignition switch 30 is input via the engine start key, the engine control of the second control device 5B can be performed, and when the off signal of the ignition switch 30 is input, the engine of the second control device 5B. Control cannot be performed (stops). Further, the first control device 5A can be controlled by inputting the ON signal of the ignition switch 30, and the first control device 5A cannot be controlled by the OFF signal of the ignition switch 30. Yes. The engine control in the second control device 5B is the same as general diesel engine control. For example, in the control of the injector 27, the fuel injection amount, the injection timing, and the fuel injection rate are set, and the supply pump 29 and the common rail are set. In the control 28, the fuel injection pressure is set.

The traveling system and working system of the tractor 2 can be controlled by the first control device 5A and the second control device 5B described above. Note that the control of the traveling system and the working system of the tractor 2 is not limited to that described above.
A wireless terminal 4 is connected to the first control device 5A. The wireless terminal 4 is capable of receiving various information from outside and transmitting information on the tractor 2 to the outside. For example, the wireless terminal 4 receives the permission signal S from the outside or transmits unique information for specifying the tractor 2 to the outside. The wireless terminal 4 only needs to be capable of exchanging information between the work implement 2 and the outside (network N) within a predetermined wireless communication area 7. Wi-Fi (registered trademark), Bluetooth ( Registered trademark), zigbee (registered trademark), and the like, for example, are general wireless communication apparatuses having a communication distance of several tens to several hundreds of meters.

In the tractor 2, while the control of the traveling system and the working system is normally performed within a predetermined use time limit, the control of the traveling system and the work system is limited when the use time limit is exceeded. ing. These controls are performed by the first control device 5A and the second control device 5B. Hereinafter, the first control device 5A will be described as an example.
The first control device 5 </ b> A includes an expiration date storage unit 40, an operation limitation unit 41, and an expiration date extension unit 42.

The expiration date storage means 40 stores the expiration date used by the tractor 2, that is, the expiration date (usage date) that can be used as usual, and a storage unit (nonvolatile memory) provided in the first control device 5A. Etc.
The expiration date is, for example, the remaining time (remaining time) that can be used and the date (date) until it can be used. When the expiration date is the remaining time, the remaining time is counted down by an internal timer such as the first control device 5A, and the remaining time counted down is updated in the storage unit 40. The remaining time may be a numerical value expressed in hours and minutes or a numerical value expressed in remaining days.

When the expiration date is a due date, the due date is stored in the storage unit 40. The expiration date may be set using a mounting device (for example, a display device) mounted on the tractor 2 and stored in the storage unit 40, or may be set and stored using an external device separately from the tractor 2. You may make it memorize | store in the part 40. FIG.
The operation restricting means 41 restricts the operation of the drive unit when the expiration date is reached, and is composed of a stored program or the like stored in the first control device 5A.

  When the expiration date is the remaining time as shown in FIG. 3 (a), the operation limiting means 41 is displayed when the remaining time decreasing with the passage of time becomes zero, or as shown in FIG. 3 (b). Thus, when the expiration date is a due date, if the permission signal S corresponding to the due date is not input by the due date, for example, even if the accelerator pedal operation amount is input, the accelerator pedal operation amount is zero (operating Normal control to the second control device 5B is limited. That is, when the operation restricting means 41 is activated, the second control device 5B cannot perform normal control corresponding to the accelerator pedal, the operation of the engine 11 is restricted, and the traveling of the tractor 2 can be stopped.

   The stop (restriction) of the normal control of the operation unit by the operation restriction unit 41 is not limited to that described above. For example, the first control device 5A controls the transmission (operation unit) 12 based on the shift lever position, but the operation restriction means 41 performs normal control of the transmission 12 based on the shift lever position. Alternatively, the normal control of the three-point link mechanism (operation unit) 16 may not be performed.

  In addition, when the operation restriction means 41 is provided in the second control device 5 instead of being provided in the first control device 5A and the operation restriction means 41 is operated, the second control device 5B cannot perform normal control of the engine 11. Thus, the engine 11 may be completely stopped. Normal control refers to all control operations that the first control device 5A and the second control device 5B can perform without restriction.

  As described above, the operation restricting means 41 restricts the normal control of the control device 5 such as the first control device 5A and the second control device 5B when the expiration date is reached, and thereby the engine 11, the transmission device 12, The operation of the drive unit such as the three-point link mechanism 16 is limited. Although the operation restriction means 41 restricts the operation of the operation unit, the restriction here includes not only stopping a part of the operation but also stopping the operation completely.

The expiration date extension means 42 extends the expiration date when the wireless terminal 4 receives the permission signal S when the tractor 2 enters the wireless communication area 7, and is stored in the first control device 5A. It is composed of stored programs.
Specifically, the expiration date extension means 42 receives the permission signal S corresponding to the tractor 2 when the wireless terminal 4 receives the permission signal S and inputs the permission signal S to the first controller 5A via the wireless terminal 4. As shown in FIG. 4A, when the expiration date stored in the storage unit 40 is the remaining time, the remaining time stored in the storage unit 40 is lengthened, as shown in FIG. If the expiration date stored in the storage unit 40 is a due date, the due date is updated to a new due date that is earlier than the current date. When a plurality of due dates are stored in advance in the storage unit 40 as the expiration date, each time the permission signal S is input, the due date used for the next operation restriction is made newer than the current date. . As shown in FIG. 4C, there are three due dates, and each time the permission signal S is input, the expiration date extension means 42 slides the due date for limiting the operation to a new due date. For example, the expiration date extension means 42 changes the date for limiting the operation from April 20, 2011 to May 20, 2011, which is a new date.

Now, when the wireless terminal 4 receives the permission signal S from the outside, the expiration date extension means 42 collates whether or not the received permission signal S is a signal for its own tractor 2, and when the collation is established. The expiration date may be extended by accepting the permission signal S.
Specifically, the expiration date extension means 42 includes a collation unit 45 that collates the unique information transmitted together with the permission signal S from the outside with its own unique information stored in the storage unit 40 of the first control device 5A, and a collation unit An extension permission unit 46 is provided that extends the expiration date by the permission signal S when the verification is established by 45 and does not extend the expiration date by the permission signal S when the verification is not established by the verification unit 45.

Thus, by providing the collation part 45 and the extension permission part 46, it is possible to extend the expiration date more reliably.
Next, the price payment management system 1 for the work machine according to the present invention will be described in detail together with the operation of the work machine 2 described above.
As shown in FIG. 1, in order to receive the permission signal S, the wireless communication area 7 of the wireless terminal 4 is set to be approximately the same size as the storage location for storing the purchased tractor 2. That is, in the work machine price payment management system 1, the permission signal S can be received by the wireless terminal 4 when the tractor 2 is in the storage location, and the tractor 2 is separated from the storage location and detached. The wireless terminal 4 cannot receive the permission signal S. As a result, the permission signal S cannot be received unless the tractor 2 purchased by the purchaser of the tractor 2 is placed in the storage location, and the expiration date cannot be extended outside the storage location. The storage location (wireless communication area 7) differs depending on the purchaser. For example, when a farming user is a purchaser, a farmer's warehouse or the like serves as a storage location, and a rental company engaged in a rental business. Is a purchase place, the place for temporarily storing the tractor 2 to be rented is the storage place. The size of the wireless communication area 7 of the wireless terminal 4 may be set as appropriate by the purchaser. For example, a transmitter / receiver 8 that can perform wireless communication with the wireless terminal 4 and perform communication with the network N is installed in a storage location, and the wireless communication area 7 is set according to the settings of the transmitter / receiver 8 and the wireless terminal 4. Is preferably set.

  The payment management server 3 is installed in a financial company (finance company) that pays the purchase price of the tractor 2 on behalf of the purchaser to a seller such as a dealer or a manufacturing company. As shown in FIG. 5, the payment management server 3 includes unique information for specifying the tractor 2 purchased by the purchaser, purchaser information for specifying the purchaser, and purchase price payment status (payment). Information) is stored in association with each other.

  The unique information stored in the payment management server 3 is, for example, the manufacturing number and model of the tractor 2 manufactured by the manufacturing company and the storage location of the tractor 2. The unique information may be any information as long as it can identify the tractor 2. The purchaser information is the purchaser's address, telephone number, and the like. The purchaser information may be any information as long as it can identify the purchaser.

The payment information of the purchaser is a payment date, information on whether or not the payment is made by the payment date, a payment amount, and the like, and it is possible to know the purchaser's present or past payment.
The payment management server 3 includes an expiration date output unit 50 and a permission output unit 51. The expiration date output means 50 and the permission output means 51 are constituted by programs stored in the payment management server 3.

The expiration date output means 50 and the permission output means 51 will be described in detail.
When a financial company pays the purchase price of the tractor 2 on behalf of the purchaser to the seller in advance, prior to the collective payment of the purchase price by the financial company, as shown in FIG. Thus, a payment plan table 52 for making installment payments is created. In the payment plan table 52, payment information such as the number of payments made by the purchaser to the financial company, payment date, payment amount, etc. is shown. Such payment information is stored in the payment management server 3. The

  The expiry date output means 50, when the financial company completes the payment of the purchase price of the tractor 2 to the manufacturer of the tractor, for example, on behalf of the purchaser, , The data is output to the wireless terminal 4 of the tractor 2 for which payment settlement is completed via the network N. At this time, by outputting (transmitting) the unique information of the tractor 2 together with the payment due date to the wireless terminal 4, the payment due date can be easily notified to the tractor 2.

  As shown in FIG. 6B, for example, when the due date for the tractor 2 whose unique information is “manufacturing number 10012, model M115A” is determined by the payment plan table 52, the expiration date output means 50 transmits each payment due date for six times to the network N together with unique information (manufacturing number 10012, model M115A). When the wireless terminal 4 receives the payment due dates for six times transmitted from the expiration date output means 50, the tractor 2 whose unique information is “manufacturing number 10012, model M115A” uses the expiration date storage means 40 for each payment date. Store in (storage unit 40).

The purchaser pays a predetermined payment amount by the due date to the financial company that has paid for the tractor 2 collectively. When payment is made from the purchaser by the due date, payment is notified to the payment management server 3, and the payment information of the purchaser of the payment management server 3 is automatically updated.
As shown in FIG. 7A, for example, suppose that the third payment date (payment time limit) is April 20, 2011 for the tractor 2 whose unique information is “manufacturing number 10012, model M115A”. As shown in FIG. 7B, when the purchaser completes the third payment on April 10, 2011, the third payment is made, and the payment management server 3 receives the payment corresponding to the third payment. It is updated to "No" (with payment). As shown in FIG. 7C, the permission output means 51 transmits a permission signal S for the unique information “manufacturing number 10012, model M115A” to the network N at the time when the third payment is made and updated. If the purchaser has not completed the third payment by April 20, 2011, the permission output means 51 does not transmit the permission signal S.

When the tractor 2 whose unique information is “manufacturing number 10012, model M115A” receives the permission signal S in the third payment at the wireless terminal 4, the expiration date extension means 42 sends the fourth payment due date (May 20, 2011 Day) is a due date for limiting the operation.
In this way, the payment management server 3 informs the tractor 2 of the expiration date (payment due date) through wireless communication means and outputs a permission signal S through the communication means when a predetermined amount is paid by the payment due date. The expiration date of the tractor 2 can be extended. On the other hand, if the predetermined amount is not paid by the payment date, the permission signal S is not output, so that the operation of the tractor 2 can be limited and stopped (after the payment date, the operation of the tractor 2 is limited). Is added). And the payment management server 3 transmits the permission signal S whenever payment is completed. When the last payment date is completed, a signal indicating that the last payment has been completed is added to the permission signal S, and when the last payment completion permission signal S is received on the tractor 2 side, the expiration date is set to indefinite (use The tractor 2 can be used for a long period of time. When receiving the final payment completion permission signal S, the tractor 2 side (first control device 5A) switches the operation restricting means 41 from valid to invalid and holds the invalidity.

  As described above, according to the present invention, since the work implement 2 includes the expiration date storage means 40, the operation restriction means 41, the expiration date extension means 42, and the wireless terminal 4, the permission signal is displayed before the expiration date. The use of the work implement 2 can be extended by receiving S, and the work implement 2 can be used repeatedly over a long period by repeatedly extending the expiration date. On the other hand, if the expiration date comes, the use of the work machine 2 can be restricted.

  In particular, when the expiration date is the payment date for the work machine 2, the purchaser of the work machine 2 can continue to use the work machine 2 by paying the price before the payment date. If the price cannot be paid before, the operation of the work machine 2 can be restricted by restricting the operation of the work machine 2. If the financial company pays the price of the work machine 2 on behalf of the purchaser, the operation of the work machine 2 can be restricted and stopped when the payment is delayed. 2 can be recovered. Therefore, it is possible to improve the creditworthiness at the time of purchase of the work machine 2.

  Now, it is common to use the work equipment 2 after purchase after leaving or returning from the storage location (while going back and forth), and usually it will not return to the storage location for a long time. There is no. In the present invention, the permission signal S for extending the expiration date can be received only at the storage location (wireless communication area 7) determined by the purchaser or the like. As a result, it is possible to prevent the abuse of the work machine 2 after purchase. For example, even if the purchaser is unable to pay the price due to financial difficulties during the payment period and the purchaser makes a plan to forcibly resell the work equipment 2, the work equipment 2 remains in the storage location. Since the use of the work machine 2 cannot be extended unless it returns, resale of the work machine 2 due to such circumstances can be suppressed.

Also, even if the purchaser plans to take the work equipment 2 away from the storage location during the payment period and make a plan to escape, the use of the work equipment 2 will be extended unless it returns to the storage location in the same way as resale. Since it becomes the structure which cannot be performed, the escape of the working machine 2 by such a situation 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.

The expiration date storage means 40, the operation limitation means 41, the expiration date extension means 42, etc. are not limited to being provided in the control device 5 described above, but the control device 5 mounted on the tractor 2 (work machine 2) 1. Any device may be used as long as it is. As described above, the work machine 2 is not limited to the tractor 2 and may be a backhoe, a combiner, or a transplanter.
As described above, the expiration date output means 50 transmits the payment due date determined in the payment plan table 52 to the wireless terminal 4 as the expiration date. However, the expiration date may not be the same as the payment due date. The due date may be a payment date plus a grace period (for example, one week). Further, the expiration date output by the expiration date output means 50 is a due date designated as a date, but it may be the number of days. In the price payment management system 1, when the expiration date is the number of days, it may be the number of days from the previous payment date to the next payment date, or may be the number of days plus a grace period.
