Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a sales system diagram of a work machine.
First, a work machine sales system, that is, a work machine sales method will be described.
The work machine sales system 1A sells, for example, a work machine 2 such as a tractor, a backhoe, and a combiner at a store 3, and the work machine 2 is manufactured from the manufacturing company 4 that manufactures the work machine 2 at each store 3. (For example, the store A and the store B) are delivered and the work machine 2 is placed in each store 3 for sale. Sales management of the work machine 2 is performed by a sales management company 5 entrusted by the manufacturing company 4. A management server 6 for managing sales of the work machine 2 is installed.

The management server 6 can be connected to a computer of the manufacturing company 4 or a store terminal 7 installed in the store 3 via a wired or wireless network (electric communication network) 8.
This management server 6 is, for example, how many working machines 2 are sold at each store 3 (each dealer) that sells the working machines 2, and how many working machines 2 are not sold. It is for grasping the sales situation.

As shown in FIG. 2 (a), the management server 6 stores unique information (manufacturing number, model) of the work machine 2 delivered for each store 3. In other words, the unique information of the work machine 2 delivered to each store 3 from the manufacturing company 4 via the network 8 is notified to the management server 6, whereby the delivery status in the management server 6 is updated. . Further, the management server 6 stores the price of the work machine 2 and the management sales status indicating whether the work machine 2 has been sold at the store 3.

Therefore, by looking at the information stored in the management server 6, it is possible to know which work machine 2 is sold at which store 3.
For example, as shown in FIG. 2A, the management and sales status of the store A, the production number “10004”, and the model “M135A” is already sold “O”, so this work machine 2 is sold. It turns out that.

On the other hand, since the management sales status of the store B, the production number “10201”, and the model “M135A” is not sold “×”, the work machine 2 is not sold.
The unique information of the work machine 2 is information for identifying the work machine 2. For example, an ID (identification) assigned to each work machine 2 may be used as the unique information of the work machine 2, but in this embodiment, it is combined with the manufacturing number and model of the work machine 2. Since the work machine 2 can be specified by this, it is made up of a production number and a model.

The store terminal 7 installed in the store 3 is composed of a personal computer, for example, and can access the management server 6 via the network 8. The store terminal 7 notifies the management server 6 of the sales status of the work machine 2 in the store 3 and the delivery status of the work machine 2. The store terminal 7 may be anything as long as it notifies the management server 6 of the sales status and delivery status of the work machine 2, and may be a communication terminal such as a mobile computer.

The method of notifying the management server 6 of the sales status and delivery status in the store 3 at the store terminal 7 is as follows.
First, when a salesperson belonging to the store 3 accesses the management server 6 using the store terminal 7, the management server 6 permits access to the store terminal 7. Then, the management sales status and delivery status (delivery information) in the management server 6 can be rewritten using the store terminal 7.

For example, as shown in FIG. 2B, in the management server 6, the management sales status of the store A, the production number “10004”, the model “M135A” is not sold, and the delivery status is not yet. Delivery is “×”. Here, by accessing the management server 6 at the store terminal 7 of the store 3 (store A), the management sales status of the store A, the production number “10004”, and the model “M135A” is rewritten to “sold” “O”. At the same time, the delivery status can be rewritten to “○”.

In this embodiment, the management server 6 is accessed from the store terminal 7 and the management sales status and delivery status in the management server 6 are rewritten using the store terminal 7. As shown in FIG. 2 (c), the management server 6 is prepared by creating a sales situation and a delivery situation in advance using the store terminal 7 and uploading the sale situation and the delivery situation from the store terminal 7 to the management server 6. You may rewrite the management sales status and delivery status. Further, an employee of the sales management company 5 or the like may be able to rewrite the management sales status and delivery status in the management server 6 using a computer installed in the sales management company 5.

As described above, in the sales system 1A for the work machine 2, the work machine 2 is delivered from the manufacturing company 4 to the store 3, and the work machine 2 is sold in the store 3. For example, when a sales contract with the customer is established, the salesperson belonging to the store 3 uses the store terminal 7 to access the management server 6 installed in the sales management company 5 and the work machine 2 is sold. The sales status of the work machine 2 is notified. And the management sales situation of the management server 6 is rewritten by operation of the terminal 7 for shops. In addition, the work machine 2 is handed over to the customer, and the work machine 2 disappears from the store 3.

Here, in the operation restriction system for the work machine 2 according to the present invention, before the work machine 2 has been sold (for example, before the work machine 2 is delivered to a customer), the operation of the work machine 2 is restricted to the store 3. The disposed working machine 2 is prevented from being stolen.
The working machine operation restriction system of the present invention will be described below.
As described above, the operation restriction system for the work machine 2 includes the management server 6 that manages the sales of the work machine 2, and the work machine 2 that controls the work machine 2 and performs normal control of the work machine 2. A control device (for example, the first control device 20) to be performed, and a work machine wireless terminal 9 provided in the work machine 2 and connectable to the management server 6 through the network 8 are provided.

First, the configuration of the work machine 2 will be described using a tractor as an example. Further, when describing the work machine 2, the control device and the work machine wireless terminal 9 will also be described.
As shown in FIG. 6, the tractor 2 is configured by mounting an engine (for example, a diesel engine) 11, a transmission 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. Drive 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 2 can run and work by the working device 13.

FIG. 7 shows a control device that controls the traveling system and the working system in the tractor 2.
As shown in FIG. 7, the traveling system and the working system in the tractor 2 are controlled by, for example, three control devices (first control device 20, second control device 21, and third control device 22). Yes.
The first control device 20 controls the entire tractor 2 and can communicate with other control devices, that is, the second control device 21 and the third control device 22.

The first control device 20 is input 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 20 outputs a control command to the second control device 21 so that the engine 11 has 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 first control device 20 is input with an engine rotation upper limit value and an accelerator lever amount. 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 20 outputs a control command to the second control device 21 so that the rotation speed of the engine 11 does not exceed the engine rotation upper limit value. Further, when the accelerator lever amount is input, the first control device 20 sends a control command corresponding to the accelerator pedal operation amount to the second control device 21 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 20 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 a three-point link based on the input from the third control device 22. The raising / lowering of the mechanism 16 is controlled (3P raising / lowering control).
The first control device 20 is provided with a lock means 30 that locks the normal control of the tractor 2. That is, the lock means 30 holds that the sales incomplete signal S1 is input when the sales incomplete signal S1 indicating that the work machine 2 is incompletely sold is input as will be described later. The first control device 20 is restricted so as not to perform normal control. The lock unit 30 is configured by a program written in the first control device 20. In addition, unique information for specifying the tractor 2 is stored in the internal memory 25 of the first control device 20.

The second control device 21 (engine computer unit) mainly controls the engine 11 and is based on inputs such as an accelerator pedal operation amount, a crank position, and a cam position from the first control device 20. 27, the common rail 28, the supply pump 29 and the like are controlled. The engine control in the second control device 21 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 controlled. In the control 28, the fuel injection pressure is set.

The third control device 22 sends a predetermined input signal to the first control device 20 or the second control device 21 based on an input of an operation system (such as a switch) input to the first control device 20 or the second control device 21. Is output.
The work machine wireless terminal 9 is connected to the first control device 20 described above. The work machine radio terminal 9 can communicate with a radio transceiver installed in the store 3 and can communicate with the management server 6 via the radio transceiver 33.

The work machine radio terminal 9 is an active radio terminal (radio machine) that emits radio waves. For example, the work machine radio terminal 9 transmits the unique information of the work machine 2 (tractor 2) stored in the first control device 20 to the outside. Or various tractor 2 information can be transmitted to the outside. In addition, the work machine wireless terminal 9 can receive various information from the outside and transmit the received information to the first control device 20. For example, when receiving the sales incomplete signal S1 transmitted from the management server 6, the work equipment wireless terminal 9 transmits the sales incomplete signal S1 to the first control device 20.

As described above, in such a tractor 2, when the work machine wireless terminal 9 receives the sales incomplete signal S <b> 1 transmitted from the management server 6 and the sales incomplete signal S <b> 1 is input to the first control device 20, The lock means 30 of the first control device 20 works to hold the lock signal in the internal memory 25 of the first control device 20 or the like. When the lock signal is held in the first control device 20, for example, even if the operation amount of the accelerator pedal is input by the lock means 30 of the first control device 20, the control command is not output to the second control device 21, The normal control to the second control device 21 is not performed.

In other words, the first control device 20 locks the normal control to the work implement 2 when the lock means 30 is activated therein, so that the engine 11 is not started as described above.
Note that the normal control is all control operations that can be performed by the first control device 20, and that the normal control is locked (stopped or limited) is part of the control that can be performed by the normal control. The control is stopped or restricted, that is, the control is not intentionally performed. That is, when the normal control is stopped (restricted), as described above, even if the engine 11 does not move or the engine 11 moves, the engine speed or the like does not increase according to the operation amount of the accelerator pedal.

The stop (restriction) of the normal control by the first control device 20 is not limited to the one described above. For example, the first control device 20 controls the transmission 12 based on the shift lever position. When the locking unit 30 is activated in the first control device 20, the transmission 12 may not be controlled based on the shift lever position. In addition, the first control device 20 is configured to control the lifting and lowering of the three-point link mechanism 16 based on the input from the third control device 22, but when the lock means 30 works in the first control device 20. The three-point link mechanism 16 may not be lifted or lowered based on the input from the third control device 22, and for example, the three-point link mechanism 16 may be lowered so that it cannot be raised.

As described above, the tractor 2 stops normal operation when the sales incomplete signal S1 is input to the work equipment wireless terminal 9 (first control device 20), and does not operate normally. That is, the operation of the tractor 2 is limited.
Since the tractor 2 may be operated until the tractor 2 is delivered from the manufacturing company 4 to the store 3 (until delivery is completed), the first control is performed while the tractor 2 is delivered from the manufacturing company 4 to the store 3. The device 20 is in a state where normal control can be performed. In other words, when the tractor 2 comes out of the manufacturing company 4, it is assumed that the normal control is not stopped by the first control device 20.

In addition, once the lock unit 30 is activated, the first control device 20 preferably continuously holds the lock signal.
Next, the management server that transmits the sales incomplete signal will be described in detail.
When the tractor 2 delivered to the store 3 has not been sold, that is, when the sale has not been completed, the management server 6 has the tractor 2 (work equipment wireless terminal) arranged in the store 3 via the network 8 when the sale is not completed. 9) means for transmitting (incomplete transmission means 40). For example, the management server 6 may include the tractor 2 (work equipment wireless terminal) disposed in the store 3 immediately after the store 3 is notified that the tractor 2 has been delivered to the store 3 (delivery of the tractor 2 is completed). 9) A sales incomplete signal S1 is transmitted.

As shown in FIG. 3, when the store A notifies that the delivery of the tractor 2 having the production number “10004” and the model “M135A” is completed, the delivery status is updated in the management server 6 (delivery “ X "to delivery" ○ "). At the time when the delivery completion of the management server 6 is notified, the incomplete delivery signal S1 of the management server 6 is sent to the tractor 2 of the production number “10004” and the model “M135A”.

Accordingly, since the management server 6 transmits the sales incomplete signal S1 to the tractor 2 whose sales are not completed (sales are not completed), the operation of the tractors 2 whose sales are not completed may be limited. it can.
The delivery status may be updated by a salesperson in the store 3 accessing the management server 6 using the store terminal 7, or an employee of the sales management company 5 may store the store terminal in the management server 6. 7 may be performed by accessing the management server 6 using a terminal different from 7 or the like, and is not particularly limited.

Further, the method for specifying the work equipment wireless terminal 9 mounted on the tractor 2 is not particularly limited. For example, a wireless address (address in the wireless network 8) is allocated in advance to the work machine wireless terminal 9, and the management server 6 associates and stores the unique information of the tractor 2 and the wireless address. May transmit the unique information and the communication information to the wireless transceiver 233 when transmitting the sales incomplete signal S1, so that the work equipment wireless terminal 9 can be identified. Further, if the unique information of the tractor 2 is known on the wireless transceiver 233 side, the work equipment wireless terminal 9 may be specified.

According to the operation restriction system for the work machine 2 of the present invention, the management server 6, the first control device 20 that is provided in the work machine 2 and controls the work machine 2, and the work machine wireless terminal 9 are provided. The management server 6 includes incomplete transmission means 40 for transmitting a sales incomplete signal S1 indicating that sales are incomplete to the work equipment wireless terminal 9 via the network 8 when the work equipment 2 is incomplete sales. The work machine wireless terminal 9 is configured to output the received sales incomplete signal S1 to the first control device 20, and the first control device 20 operates when the sales incompletion signal S1 is input. It is configured to restrict normal control to the machine 2.

According to this, since the sales incomplete signal S1 is transmitted to the work implement 2 by the management server 6 that manages the sale, the operation is restricted for the work implement 2 that has not been sold. Since the working machine 2 cannot be moved normally, it is possible to prevent the working machine 2 from being stolen.
4 and 5 show a modified example in which a sales incomplete signal S1 is transmitted from the management server 6 to the work equipment wireless terminal 9 of the tractor 2.

In FIG. 4, when the management server 6 requests a response to the work equipment wireless terminal 9 and the work equipment wireless terminal 9 receives a response to the response request, the sales incomplete signal S1 is transmitted. This is an example.
More specifically, when the tractor 2 is sent from the manufacturing company 4 to the store 3 and delivered to the store 3, the work equipment wireless terminal 9 of the delivered tractor 2 can be used (wireless transmission / reception provided in the store 3). Ready to wirelessly communicate with the device 233). For example, a salesperson of the store 3 turns on the power of the work machine wireless terminal 9.

Note that the method for making the work equipment wireless terminal 9 ready to use is not limited to the method of turning on the power, but the setting is made to enable the network 8 between the wireless transceiver 233 and the work equipment wireless terminal 9. Or other methods may be used.
The management server 6 transmits a response signal (response request) to the radio transceiver 233 of the store 3 so as to respond to a predetermined tractor 2 (work machine radio terminal 9). Then, a response command is transmitted to the work machine radio terminal 9 via the radio transceiver 233.

Here, if the work equipment wireless terminal 9 can perform wireless communication with the wireless transmitter / receiver 233, that is, can receive a response signal, the work equipment wireless terminal 9 receives the response signal and transmits / receives the wireless signal. A response to the response request is sent to the device 233. The wireless transceiver 233 notifies the management server 6 of a response from the work machine wireless terminal 9. When a response is received from the work machine wireless terminal 9, the management server 6 transmits a sales incomplete signal S 1 to the work machine wireless terminal 9 that has responded.

In this way, it is possible to notify the management server 6 that the delivery of the tractor 2 to the store 3 has been completed (delivery completed) by simply using the wireless terminal 9 for the work machine, which is very simple. The sales incomplete signal S1 can be input to the tractor 2 (first control device 20).
FIG. 5 shows that after the tractor 2 is delivered to the store 3, when the sales status is notified from the store terminal 7, the sales status is sold to the work equipment wireless terminal 9 of the tractor 2 that is not yet sold. An example in which the incomplete signal S1 is transmitted by the management server 6 is shown.

Specifically, when the tractor 2 is sent from the manufacturing company 4 to the store 3 and delivered to the store 3, as described above, the salesperson of the store 3 uses the store terminal 7 and the like to the management server 6 The stored information indicating completion of delivery of the tractor 2 is updated (from delivery “×” to delivery “O”).
Thereafter, when the sales status at the store 3 is notified using the store terminal 7, the management server 6 notifies the work equipment wireless terminal 9 of the tractor 2 that has not been sold yet when the sales status is notified. A sales incomplete signal S1 is transmitted.

For example, it is assumed that delivery of the tractor 2 with the production number “10005” and the model “M135A” and the tractor 2 with the production number “10006” and the model “M135A” is completed.
It is assumed that, of the two tractors, the sales number of the tractor 2 having the production number “10006” and the model “M135A” has been sold, and the sales status of the two tractors 2 is notified to the management server 6. At this time, the sales of the tractor 2 with the production number “10006” and the model “M135A” has been completed, but the tractor 2 with the production number “10005” and the model “M135A” has not been sold. Then, the management server 6 transmits a sales incomplete signal S1 to the tractor 2 having the production number “10005” and the model “M135A”.

In this way, after the delivery of the tractor 2 to the store 3 is completed, the sales incomplete signal S1 can be transmitted only to the unsold tractor 2 when the sales situation changes. As a result, since the sales incomplete signal S1 is not transmitted to the tractor 2 which has been sold immediately after the delivery is completed, the tractor 2 sold immediately after the delivery is completed can be moved immediately.
In the embodiment described above, the lock means 30 is activated when the sales incomplete signal S1 is input to the first control device 20, but instead, the management server 6 and the wireless You may change operation | movement of the transmitter / receiver 233, the radio | wireless terminal 9 for work machines, and the 1st control apparatus 20. FIG.
For example, when the information indicating delivery completion in the management server 6 is rewritten to delivery completed, the management server 6 sends the unique information of the tractor 2 that has been delivered together with the sales incomplete signal S1 to the wireless transceiver 233. Send. When the wireless transceiver 233 receives the sales incomplete signal S1 and the unique information of the tractor 2 from the management server 6, the wireless transceiver 233 transmits the sales incomplete signal S1 and the unique information of the tractor 2 to the plurality of work equipment wireless terminals 9. To do. The work machine radio terminal 9 outputs the sales incomplete signal S1 and the unique information of the tractor 2 to the first control device 20.

The first control device 20 collates the unique information stored therein with the unique information sent from the work equipment wireless terminal 9, and the unique information sent from the work equipment wireless terminal 9 becomes the first control device. If it is stored in 20, the input of the sales incomplete signal S1 is valid and the lock means 30 is activated. Here, when the first control device 20 collates the unique information stored therein with the unique information sent from the work equipment wireless terminal 9 and the collation is not established, the first control device 20 The input of the incomplete signal S1 is invalid, and the lock unit 30 is not activated (normal control is not stopped).

In the embodiment described above, the lock signal is held when the locking means 30 of the first control device 20 is activated. However, the lock signal is released (cancellation of normal control stop, normal control). The method for releasing the lock is not particularly limited, and the following method is preferable.
First, when the managed sales status in the management server 6 is rewritten from unsold to sold, the management server 6 transmits a lock release signal to the work equipment wireless terminal 9 of the tractor 2 that has been sold. When the first control device 20 receives the lock release signal via the work machine radio terminal 9, the lock signal is deleted, that is, the operation of the lock means 30 is stopped.

Alternatively, when the management sales situation in the management server 6 is rewritten to sold, the management server 6 uses the wireless transceiver 233 to transmit the unique information of the sold tractor 2 together with the lock release signal. Transmit to the wireless terminal 9. The work machine wireless terminal 9 outputs unique information to the first control device 20 together with the lock release signal. The first control device 20 collates the unique information stored therein with the unique information sent from the work equipment wireless terminal 9, and the unique information sent from the work equipment wireless terminal 9 becomes the first control device. If it is stored at 20, the lock release signal is accepted as valid, and the normal control lock is released. When the first control device 20 collates the unique information stored therein with the unique information sent from the work equipment wireless terminal 9 and the collation is not established, the first control device 20 It is assumed to be invalid and the normal control lock is not released.

Further, after the sale of the tractor 2 is finished (at the time of delivery), a salesperson belonging to the store 3 operates the work implement 2 (operates a display device mounted on the work implement 2 to perform a special operation). The lock signal may be erased. In addition, a terminal that allows the salesperson to access the first control device 20 is prepared, and a special code (such as a password) is transmitted to the first control device 20 by this terminal, and the first control device 20 inputs the special code. When this is done, the lock signal may be erased.

FIG. 8 shows a sales system diagram for selling a work machine at a store.
This work machine sales system 1B sells the work machine 2 such as a tractor at the store 3 in the same manner as in the above-described embodiment. 3 is delivered and the work machine 2 is placed in the store 3 for sale. Hereinafter, a tractor will be described as an example. In addition, the description of the configuration (common part) similar to that of the tractor 2 described above will be omitted, and different configurations will be described.

In the store 3, a storage place (work machine display area) E for displaying the tractor 2 is determined, and the tractor 2 is arranged in the work machine display area E. Further, in the store 3, for example, a store terminal 4 composed of a personal computer is installed. The store terminal 4 performs various management such as the sales status of the tractor 2. For example, the store terminal 4 can manage on the computer whether or not the tractor 2 placed in the work machine display area E of the store 3 has been sold. It is like that.

Furthermore, in the work implement display area E, a wireless transceiver 133 for performing wireless communication with the work implement wireless terminal 109 mounted on the tractor 2 is provided. Description of the wireless transceiver 133 that is common to the wireless transceiver 33 described above is omitted. In addition, you may install the radio | wireless transmitter / receiver 133 around the working machine display area E (for example, in the building of the store 3). Further, the wireless communication range between the work machine wireless terminal 109 and the wireless transceiver 133 is not limited, but is preferably set to be approximately the same size as the work machine display area E. For example, the work machine wireless terminal 109 may be set so that the radio wave of the work machine wireless terminal 109 reaches the wireless transceiver 133 regardless of where the tractor equipped with the work machine wireless terminal 109 is located in the work machine display area E. preferable. The wireless communication range is preferably set to 500 m or less, for example.

In the work machine operation restriction system 1B shown in FIG. 8, when the tractor 2 is in the work machine display area E, the tractor 2 can be moved as usual, and the sale of the tractor 2 is not completed. When the tractor 2 comes out of the work implement display area E, the operation of the tractor 2 can be restricted.
As described above, the work machine operation restriction system 1B includes a wireless transceiver 133, a control device (first control device 120) that is provided in the work machine 2 and controls the operation of the work machine 2. The work machine wireless terminal 109 is provided in the machine 2 and performs wireless communication with the wireless transceiver 133.

As shown in FIG. 9, the tractor 2 includes, for example, three control devices (a first control device 120, a second control device 121, and a third control device 122). Hereinafter, the first control device 120, the second control device 121, and the third control device 122 are different from the above-described first control device 20, the second control device 21, and the third control device 22 by omitting the description. The configuration will be described.
The first control device 120 is provided with external input means 123 for inputting a signal from the outside (for example, a sales incomplete signal indicating that sales of the tractor 2 are not completed). This external input means 123 inputs infrared rays (infrared data), inserts an IC card, connects to a USB (Universal Serial Bus) memory, connects to an IEEE 1394 terminal, and connects to an SD card. Whatever is done, it can be anything. The first control device 120 is provided with a signal storage unit 125 that stores an external signal.
The signal storage unit 125 is an internal memory provided in the first control device 120, and can hold a sales incomplete signal S1. In the case where the external input unit 123 accepts an external storage medium (media), the storage medium received by the external input unit 123 may be used as the signal storage unit 125. The signal storage unit 125 stores unique information for specifying the tractor 2.

The first control device 120 is provided with a lock unit 130 that locks the normal control of the tractor 2 (limits normal control). As will be described later, the lock unit 130 is configured so that the reception intensity of the work equipment wireless terminal 109 is predetermined in a state where the sales incomplete signal S1 indicating that the tractor 2 is incomplete is stored in the signal storage unit 125. When the value is equal to or less than the value, the normal control is not performed as in the case of the lock unit 30 described above. The lock unit 130 is configured by a program or the like written in the first control device 120.

Note that in a state where the sales incomplete signal S1 is not stored in the signal storage unit 125 (blank), the lock unit 130 does not operate even if the reception intensity of the work equipment wireless terminal 109 is equal to or lower than a predetermined value, and the first The control device 120 performs control as usual.
Furthermore, a work machine wireless terminal 109 is connected to the first control device 120. The work machine wireless terminal 109 can communicate with a wireless transceiver 133 installed in the store 3. The work machine wireless terminal 109 is, for example, an active wireless terminal (radio device) that transmits radio waves. The work machine radio terminal 109 is provided with a signal measurement unit that measures the reception intensity (reception signal intensity) of the radio wave transmitted from the radio transceiver 133, and the reception intensity measured by the signal measurement unit is a first control. It is input to the device 120.

FIG. 10 shows a flow from input of the sales incomplete signal S1 to prevention of theft. As shown in FIG. 10, first, the tractor 2 is delivered from the manufacturing company to the store 3, and the tractor 2 is placed in the work implement display area E. In addition, the salesperson of the store 3 inputs the sales incomplete signal S1 to the signal storage unit 125 of the first control device 120 of the work machine 2 placed in the work machine display area E using the external input means 123 such as infrared communication. . That is, the sales non-completion signal S <b> 1 is stored in the first control device 120 of the work machine 2 placed in the work machine display area E of the store 3.

In addition, in the work machine 2 placed in the work machine display area E, communication between the work machine wireless terminal 109 mounted on the work machine 2 and the wireless transceiver 133 placed in the store 3 (work machine display area E). On a regular basis (for example, every few minutes, every day, every week).
Now, in such a state, it is assumed that the work machine 2 placed in the work machine display area E is moved and is attempted to be carried from the work machine display area E to the outside. When there is a work implement 2 in the work implement display area E and the distance between the work implement wireless terminal 109 of the work implement 2 and the radio transceiver 133 is short, the received signal strength at the work implement radio terminal 109 is strong. . If the work implement 2 is taken out of the work implement display area E, the distance between the work implement radio terminal 109 and the radio transceiver 133 is increased, and thus the received signal strength at the work implement radio terminal 109 is weakened ( descend).

Here, for example, when the received signal strength decreases and the received signal strength falls below a predetermined value, the locking means 130 of the first control device 120 of the work machine 2 operates. When the locking means 130 is activated, for example, the first control device 120 does not output a control command to the second control device 121 even when an operation amount of the accelerator pedal is input, and normal control to the second control device 121 is performed. Do not do. In other words, the first control device 120 locks the normal control to the work implement 2 when the locking means 130 is activated therein, and stops the engine 11 as described above, or even if the engine 11 is running, Correspondingly, the speed and engine speed should not be increased.

Note that the received signal strength is equal to or less than a predetermined value because the work implement 2 is out of the work implement display area E or the work implement 2 is located at the boundary between the work implement display area E and the outside. It is set so that it can be determined whether or not there is a specific numerical value. In other words, the setting of the received signal strength for operating the lock means 130 is performed when the work implement 2 goes out of the work implement display area E and the radio between the work implement radio terminal 109 and the radio transceiver 133 is interrupted. The value may be a value, or may be a value when the work machine 2 is located at the boundary between the work machine display area E and the outside.

According to the work machine operation restriction system 1B, the wireless transmitter / receiver 133, the first control device 120 provided in the work machine 2 and controlling the operation of the work machine 2, and the work machine 2 provided for wireless use. The work machine wireless terminal 109 that performs wireless communication with the transceiver 133 is provided, and the first control device 120 is provided with a signal storage unit 125 that stores the sales incomplete signal S1. When the received signal strength of the wireless terminal for work implement 109 becomes a predetermined value or less in a state where the sales incompletion signal S1 is stored in the signal storage unit 125, normal control to the work implement is limited. Yes.

According to this, even if the unsold work machine 2 placed in a storage place such as the work machine display area E is moved from the work machine display area E to another place for the purpose of theft, Since the operation of the machine 2 is limited, it cannot be moved normally.
Therefore, even if the work machine 2 is stolen from the work machine display area E, the work machine 2 does not move as usual, which serves as a deterrent and can prevent the work machine 2 from being stolen.

FIG. 11 shows a modification of the work machine operation restriction system. The description of the same configuration as that of the above-described embodiment is omitted.
As shown in FIG. 11, the sales incompletion signal S <b> 1 may be transmitted to the work machine wireless terminal 109 of the tractor 2 using the store terminal 4 installed in the store 3. Specifically, the sales incompletion signal S <b> 1 output from the store terminal 4 is transmitted to the work machine radio terminal 109 via the radio transceiver 133. For example, the unique information of the tractor 2 delivered to the store 3 is stored in the store terminal 4, and the delivery status that indicates whether or not the delivery is completed for each tractor 2 is also stored.

Then, the delivery status can be rewritten at the store terminal 4, and the delivery to the store 3 in the work machine 2 is completed and the delivery status is rewritten from undelivered to delivered (after delivery is completed). In addition, a sales incomplete signal S1 is transmitted from the store terminal 4 to the tractor 2 which has been delivered.
In the operation restriction system for the work machine 2 according to the modified example, the store 3 is provided with a store terminal 4 that transmits a sales incompletion signal S1 to the radio transceiver 133, and the radio transceiver 133 receives the sales incompletion signal S1. Is transmitted to the work machine radio terminal 109, the work machine radio terminal 109 is configured to output a sales incomplete signal S1 to the first control device 120, and the signal storage unit 125 performs the first control. When the sales incomplete signal S1 is input to the device 120, the sales incomplete signal S1 is stored.

According to this, for example, since the sales incomplete signal S1 can be transmitted to the work machine 2 placed in the store 3 using the store terminal 4, it is sold to the first control device 120 (signal storage unit 125). The work of storing the incomplete signal S1 is very easy.
In the above-described embodiment, a method for erasing the sales incomplete signal S1 stored in the first control device 120 (signal storage unit 125) is not described. For example, after the sales of the tractor 2 is completed ( The salesperson belonging to the store 3 at the time of delivery) operates the work machine 2 (operates a display device mounted on the work machine 2 to perform a special operation) so that the sales incomplete signal S1 is erased. May be. In addition, a terminal that allows the salesperson to access the first control device 120 is prepared, and a special code (such as a password) is transmitted to the first control device 120 by the terminal, and the first control device 120 inputs the special code. When it is done, the sales incomplete signal S1 may be deleted.

FIG. 12 shows a sales system diagram of the work machine.
In this work machine sales system 1 </ b> C, the work machine 2 is delivered from the manufacturing company that manufactures the work machine 2 to each store 3 (for example, store A, store B), and the work machine 2 is placed at each store 3. It is supposed to sell. Sales management of the work machine 2 is performed by a sales management company 5 entrusted by the manufacturing company 4. The sales management company 5 is provided with a management server 206 for managing the sales of the work machine 2. Hereinafter, the configuration of the management server 206 that is different from that of the management server 6 will be omitted and different configurations will be described. In addition, description of common parts of the store 3 and the store terminal 7 is omitted.
In the work machine operation system 1C, before the tractor 2 is sold (for example, before the tractor 2 is handed over to the customer), it is not moved as usual, and after the sale is finished (for example, after the tractor 2 is handed over) Therefore, a certain condition is set for the operation of the tractor 2 before and after the sale of the tractor 2.

As described above, the work machine operation system 1C includes a management server 206 that manages sales of the tractor 2, and a lock signal that is provided in the tractor 2 to control the tractor 2 and lock the normal control of the tractor 2. The control apparatus (for example, 1st control apparatus) hold | maintained and the work radio | wireless terminal 209 which is provided in the tractor 2 and can be connected to the management server 206 via the network 8 are provided.

As shown in FIG. 13, the tractor 2 includes, for example, three control devices (a first control device 220, a second control device 221, and a third control device 222). Hereinafter, the first control device 220, the second control device 221, and the third control device 222 are common to the first control devices 20, 120, the second control devices 21, 121, and the third control devices 22, 122 described above. Will be omitted, and different configurations will be described.

The first control device 220 holds a lock signal that locks the normal control of the tractor 2. That is, when the manufacturing company 4 ships the tractor 2 to the store 3, a lock signal (a flag for locking) is written in the internal memory 225 of the first control device 220. In other words, the lock signal is written in the first control device 220 while the tractor 2 is moving from the manufacturing company 4 to the store 3 or until the arrangement at the store 3 is completed. The internal memory 225 stores unique information for specifying the tractor 2.

Also, the work machine wireless terminal 209 is connected to the first control device 220 described above. The work machine radio terminal 209 can communicate with the radio transceiver 233 installed in the store 3 and can communicate with the management server 206 via the radio transceiver 233. The wireless transceiver 233 will not be described in common with the wireless transceivers 33 and 133 described above.

The work machine radio terminal 209 is an active radio terminal (radio machine) that emits radio waves. For example, the work machine radio terminal 209 transmits the unique information of the tractor 2 (work machine) stored in the first control device 220 to the outside. The information of various tractors 2 can be transmitted to the outside. The work machine wireless terminal 209 can receive various information from the outside and transmit the received information to the first control device 220. For example, when the work machine wireless terminal 209 receives the lock release signal S <b> 1, the work machine wireless terminal 209 transmits the lock release signal S <b> 1 to the first control device 220.
As described above, in such a tractor 2, in a state where the lock signal is held in the first control device 220, for example, the first control device 220 controls the second control device 221 even when an operation amount of the accelerator pedal is input. A command is not output and normal control to the 2nd control device 221 is not performed like the embodiment mentioned above. That is, the first control device 220 locks (limits) the normal control to the work machine 2 so that the engine 11 does not start as described above in a state where the lock signal is held therein.

When the work machine wireless terminal 209 receives the lock release signal S1 and the lock release signal S1 is input to the first controller 220, the lock of the normal control by the lock signal is released, and the first controller 220 Based on the operation amount of the accelerator pedal, a control command is output to the second control device 221 so that the engine 11 has a predetermined rotational speed, and normal control is performed.
The first control device 220 is configured to hold the normal control unlock when the normal control lock is released by the lock release signal S1. That is, when the unlock signal S1 is input to the first control device 220 and the normal control that has been locked by the input of the unlock signal S1 is released even once, the unlock of the normal control is continuously maintained. It will be.

Thus, although the tractor 2 operates normally only when the unlock signal S1 is input, the unlock signal S1 is transmitted from the management server 206 described above. For example, the management server 206 transmits a lock release signal S1 for releasing the normal control lock to the work equipment wireless terminal 209 via the network 8 in response to a command from an external terminal such as the shop terminal 7. Release transmission means 240 is provided.

For example, when the sales status in the store 3 is notified from the store terminal 7 to the management server 206 and the management sales status in the management server 206 is already sold, it is sent to the work equipment wireless terminal 209 of the tractor 2 that has been sold. On the other hand, the management server 206 outputs the unlock signal S1 (the unlock signal S1 is output by the unlock transmission means 240).
Specifically, as shown in FIG. 2B, in the management server 206, the management sales status of the store A, the production number “10004”, and the model “M135A” is not sold “×”, but the same store 3 It is assumed that the management sales status of the store A, the production number “10004”, and the model “M135A” is rewritten to “sold” “O” by accessing the management server 206 at the store terminal 7 of (store A).

Then, the management server 206 (unlock transmission means 240) first sends an unlock signal S1 to the wireless transceiver 233 installed in the store A, and the unique information is serial number “10004” via the wireless transceiver 233. And the lock release signal S1 is sent to the work equipment wireless terminal 209 of the tractor 2 of the model “M135A”.
The method for specifying the work equipment wireless terminal 209 mounted on the tractor 2 is not particularly limited. For example, a wireless address (such as an address in the wireless network 8) is allocated to the work machine wireless terminal 209 in advance, and the management server 206 stores the unique information of the tractor 2 and the wireless address in association with each other. By transmitting the unique information and the communication information to the wireless transceiver 233 when the lock release signal S1 is transmitted, the work machine wireless terminal 209 may be identified. Further, if the unique information of the tractor 2 is known on the wireless transceiver 233 side, the work equipment wireless terminal 209 may be specified.

As shown below, the operations of the management server 206, the wireless transceiver 233, the work equipment wireless terminal 209, and the first control device 220 may be changed.
For example, the sales rewriting of the management sales status in the management server 206 may be performed by an external terminal other than the store terminal 7 or an input device (for example, a mouse, a keyboard, etc.) provided in the management server 206 You may rewrite using When the sales status in the management server 206 is changed to sold, the management server 206 transmits the unique information of the sold tractor 2 to the wireless transceiver 233 together with the unlock signal S1. When the wireless transceiver 233 receives the unlock signal S1 and the unique information of the tractor 2 from the management server 206, the wireless transceiver 233 transmits the unique information together with the unlock signal S1 to the plurality of work equipment wireless terminals 209. The work machine wireless terminal 209 outputs the unique information to the first control device 220 together with the lock release signal S1. The first control device 220 collates the unique information stored therein with the unique information sent from the work machine radio terminal 209, and the unique information sent from the work machine radio terminal 209 is the first control device. If it is stored in 220, the lock release signal S1 is accepted as valid, and the lock of the normal control is released. When the first control device 220 collates the unique information stored therein with the unique information sent from the work machine wireless terminal 209 and the collation is not established, the first control device 220 sends the lock release signal S1. Is invalid and the normal control lock is not released.

The renewal of the managed sales status in the management server 206 may be rewritten to sold when the deposit process is completed from an external terminal such as a bank.
According to the work machine operation system 1 </ b> C, the management server 206 includes a management server 206, a first control device 220, and a work machine wireless terminal 209, and the management server 206 normally connects to the work machine wireless terminal 209 via the network 8. The work machine wireless terminal 209 is configured to output the lock release signal S1 transmitted from the management server 206 to the first controller 220. The control device is configured to release the lock of the normal control by the lock signal when the lock release signal S1 is input.

According to this, the lock signal can be held in the first control device 220 before the sales are completed, and the operation of the work machine 2 can be restricted until the work machine 2 is sold. Further, since the lock release signal S1 can be transmitted from the management server 206 to the work machine 2 after the sale is completed after the sale is completed, the work machine 2 can be freely moved after the sale is completed. That is, the work machine can be prevented from being stolen by temporarily restricting the operation of the work machine, and the work machine can be moved as usual by releasing the restriction on the operation of the work machine after the sales are completed.

The first control device 220 is configured to hold the normal control unlock when the normal control lock is released by the lock release signal S1.
According to this, once unlocking is performed, the work implement 2 can be moved as usual.
The command from the external terminal to the management server 206 is made by the store terminal 7 installed in the store 3 where the work machine 2 is sold.

According to this, when the work machine 2 is sold, that is, when the work machine 2 is handed over to a customer, the work machine that has sold the unlock signal S1 via the management server 206 in response to a command from the store terminal 7 The work machine 2 can be moved as usual when the store side wants to move the work machine 2.
