Prior to the description of the operation system of the work machine, the work machine rental system will be described. The operation system of the work machine can be applied to other than the work machine rental, and is not limited to the work machine rental system described later.

FIG. 1 is a schematic diagram of a work machine rental system.
The work machine rental system 1 is a system that performs a work machine rental system such as a construction machine (for example, a backhoe) and an agricultural machine (for example, a tractor, a combine, a rice transplanter).
As shown in FIG. 1, the work machine rental system 1 includes a first management server 2 and a second management server 3.

  The first management server 2 is a server that manages the rental of the work machine 4 and is owned by, for example, a rental company. The second management server 3 is owned by a manufacturer or the like that manufactures or sells the work machine 4. The first management server 2 and the second management server 3 can exchange information with each other through the network N. The second management server 3 can provide, for example, various information (part information, specification information, operation manual, maintenance information, etc.) related to the manufacture or sale of the work machine 4 to the first management server 2. . On the other hand, the 1st management server 2 can provide the information regarding a rental to the 2nd management server 3 so that it may mention later.

  Various devices (referred to as communication devices) 5 can be connected to the first management server 2 through the network N. For example, the first management server 2 can be connected to a communication device 5 such as a personal computer (PC), a smartphone (multifunctional mobile phone), a PDA (mobile terminal), a tablet, or the like. By connecting the communication device 5 to the first management server 2, processing related to the rental of the work machine 4 can be performed.

  In order to rent the work machine 4, first, the communication device 5 is connected to the first management server 2. In response to the connection of the communication device 5, the first management server 2 displays an input screen (for example, a Web screen) on the communication device 5. On the input screen displayed on the communication device 5, items (information) necessary for renting can be input. For example, on the input screen, the borrower information (debitor's address, name, phone number, etc.), which is information related to the person (debiter) who rents the work machine, debit request information (the model of the work machine desired to be rented, the model concerned) Desired number of units, lending period, etc.).

  Based on the debit request information, the first management server 2 determines whether or not the desired work machine 4 can lend during the desired lending period, and if the work machine 4 can be lent during the desired lending period The second management server 3 is inquired about rental permission. When the second management server 3 permits the rental, the first management server 2 performs a predetermined process so that the work machine can be rented. Thus, in the work machine rental system 1, the work machine 4 is rented by linking the first management server 2 and the second management server 3.

Hereinafter, the first management server and the second management server will be described in detail.
The first management server 2 includes a first storage unit (first work machine information storage unit) 10, a second storage unit (rental information storage unit) 11, a processing unit (first processing unit) 12, and a first communication. Part 13. The 1st memory | storage part 10 and the 2nd memory | storage part 11 are comprised by the non-volatile memory. The first processing unit 12 and the first communication unit 13 are configured by electric / electronic components, programs, and the like incorporated in the first management server 2.

  The first storage unit 10 stores work machine information (work machine information) owned by the rental company. The first storage unit 10 stores, for example, a work machine management number, work machine identification information, a work machine model, and the like, as shown in FIG. 2A. The management number of the work machine is a number assigned for rental management by the rental company. The work machine identification information is information that identifies the work machine and is unique information (for example, a manufacturing number, a serial number, etc.) assigned to the work machine. The model of the work machine is a name uniquely set by the manufacturer according to the specifications of the work machine, the size of the work machine, and the like.

  The second storage unit 11 stores information on rental of the work machine (referred to as rental information). For example, as shown in FIG. 2B, the second storage unit 11 stores, as rental information, a management number of the working machine that has rented, identification information of the working machine, permission information, debiter information, a lending period, and the like. Yes. The permission information is a number (permission instruction information) indicating the permission of rental notified from the second management server 3 when performing the rental.

The 1st communication part 13 is an apparatus which transmits / receives various information with the 2nd management server 3, the communication apparatus 5, etc. FIG. The first communication unit 13 transmits and receives predetermined information according to the processes of the first management server 2, the second management server 3, and the communication device 5.
The first processing unit 12 is a part that performs various processes related to rental. For example, when the communication device 5 is connected to the first management server 2 and there is a request (input screen request) to rent the first management server 2, the first processing unit 12 To display the input screen. In addition, when the debitor information, the debit request information, etc. are input on the input screen, the first processing unit 12 determines whether or not the desired working machine can lend during the desired lending period based on the debit request information. Perform a process to determine. Specifically, the first processing unit 12 refers to the model of the work machine stored in the first storage unit 10 and calculates how many kitchens the model of the work machine desired to be rented has. That is, the first processing unit 12 calculates the number of rental companies owned by the model desired to be rented. Note that the number of possessed machines may be stored in the first storage unit 10 by arranging the work machines in advance for each model.

Then, the first processing unit 12 refers to the second storage unit 11 to calculate the number of working machines that have already been rented during the lending period (the number of lending), and the rental is determined from the number of lending and the number of owned units. Calculate the number of work machines that can be rented. The first processing unit 12 determines that the desired working machine can be lent when the rentable number is equal to or larger than the desired number.
For example, when the rentable number is three and the desired number is five, at least three working machines that are lent can be rented. In this case, the first processing unit 12 notifies the communication device 5 of the rentable number, asks the communication device 5 to change the desired number, and if the desired number after the change is less than the rentable number, the first processing unit 12 The processing unit 12 determines that lending can be performed.

  After determining that the desired working machine can be rented, that is, when a rental reservation is made for a predetermined working machine, the first processing unit 12 sends the first information to the first communication unit 13. To the second management server 3 is performed. The first information is information on a predetermined work machine, that is, a work machine that can be rented, and is information managed by the first management server 2. The first information includes a work machine management number, identification information for identifying the work machine, a model of the work machine, and the like.

In this embodiment, when a rental reservation is made for a work machine, the first processing unit 12 refers to the first storage unit 10 and the second storage unit 11 and the same work machine as the desired work machine. Specific information (referred to as first specific information) is extracted. The first communication unit 13 transmits the first information including the first specific information extracted by the first processing unit 12 and the rental permission request to the second management server 3.
The second management server 3 includes a third storage unit (second work machine information storage unit) 20, a second communication unit 21, and an issuing unit 22. The third storage unit 20 is configured by a non-volatile memory or the like. The second communication unit 21 and the issuing unit 22 are configured by electric / electronic components, programs, and the like incorporated in the second management server 3.

The 3rd memory | storage part 20 has memorize | stored the information of the manufactured working machine, or the information of the sold working machine. Information on manufactured work machines or sold work machines is referred to as second information. For example, as illustrated in FIG. 3A, the third storage unit 20 stores work machine identification information, a work machine model, and the like as the second information.
The 2nd communication part 21 is an apparatus which transmits / receives various information with the 1st management server 2 grade | etc.,. The second communication unit 21 receives or transmits predetermined information according to processing of the first management server 2, the second management server 3, and the like.

  The issuing unit 22 first refers to the first information transmitted from the first management server 2 and the second information stored in the third storage unit 20, and permits a work machine (referred to as a rental work machine) to permit the rental. Is determined. Specifically, when the first management server 2 receives the first information including the first specific information and the rental permission request, the issuing unit 22 starts the indexing process in response to the rental permission request. The issuing unit 22 determines whether or not the second specific information that matches the first specific information received by the first management server 2 is stored in the third storage unit 20.

  For example, as illustrated in FIG. 3B, when the first specific information is “K-RX253200”, the issuing unit 22 refers to the third storage unit 20 and stores “K− It is determined whether the second specific information indicated by “RX253200” is stored. In this case, since “K-RX253200” is stored as the second specifying information in the third storage unit 20, the issuing unit 22 stores the second specifying information that matches the first specifying information ( It is determined that there is a work implement.

  When there is a work machine, the issuing unit 22 sets the work machine corresponding to the first specific information (“K-RX253200”) that matches the second specific information (“K-RX253200”) as a rental work machine that permits rental. Authorize and issue command information (permission command information) indicating that it has been certified. The permission command information is information (information indicating rental permission) indicating that the work machine of the first specific information is certified as a rental work machine, and is indicated by a number of digits. The permission command information is associated with the work machine in advance, and the second specifying information (“K-RX253200”) and the permission command information are associated with each other in advance. That is, the issuing unit 22 issues permission command information associated with the second specific information in advance.

Accordingly, the issuing unit 22 issues rental permission to the work machine of the first specific information by issuing the associated permission command information to the first specific information notified from the first management server 2. I do.
In the above description, the issuing unit 22 uses the flag indicating rental permission or the like as permission command information (permission information) in the first identification information notified from the first management server 2, so that the first identification is performed. Rental permission may be given to the information work machine.

On the other hand, when the first specific information is “K-253800”, the issuing unit 22 does not store “K-253800” as the second specific information in the third storage unit 20. Determines that the second specific information that matches the first specific information is not stored (no work implement).
If there is no work machine, the issuing unit 22 sets the work machine corresponding to the first specific information (“K-253800”) as a work machine that cannot be rented, and non-permission instruction information indicating that the rental is not permitted. Issue. In this case, the disapproval command information is information (information indicating that the rental is not permitted) indicating that the work machine of the first specific information is a work machine that cannot issue a rental permission.

The second communication unit 21 of the second management server 3 transmits the permission command information or the non-permission command information to the first management server 2 when the issuing unit 22 issues the permission command information or the non-permission command information.
When the first communication unit 13 of the first management server 2 receives the permission command information or the non-permission command information, the first processing unit 12 performs processing corresponding to the permission command information or the non-permission command information. When the first management server 2 receives the permission command information, the first processing unit 12 indicates that the rental machine has been rented and the work device desired by the debiter can be rented. To be notified. In addition, the first processing unit 12 and the second storage unit 11 perform a process of updating information in the second storage unit 11. The first processing unit 12 stores, in the second storage unit 11, the management number, the first specific information of the work machine (rental work machine) for which the rental permission has been granted, permission information (permission command information), debiter information, the lending period, and the like. Send. The second storage unit 11 stores a management number, first specifying information, permission information (permission command information), debiter information, a lending period, and the like.

  On the other hand, when the first management server 2 receives the non-permission command information, the first processing unit 12 continues the process on the assumption that the rental of the work machine having the first specific information corresponding to the non-permission command information is not permitted. For example, the first processing unit 12 extracts a work machine that can be lent during the lending period, sets the work machine as a substitute machine that replaces the work machine that is not permitted to rent, and uses the first specific information of the substitute machine as the first specification information. 2 By making a notification to the management server 3, a rental permission request for an alternative device is made. The second management server 3 performs a process for determining whether or not the substitute machine is authorized as a rental work machine in the same manner as described above. When the rental permission is given to the substitute machine (receives the permission command information corresponding to the substitute machine), the first processing unit 12 rents the substitute machine instead of the work machine desired by the borrower. Information that it is possible is transmitted to the communication device 5. When receiving information indicating that the first management server 2 may be an alternative device, the first processing unit 12 notifies the communication device 5 of information indicating that the rental reservation has been completed.

Then, the first processing unit 12 obtains the management number, the management number, the first specifying information of the alternative machine (rental work machine) for which the rental permission has been granted, the permission information (permission command information), the debiter information, the lending period, etc. Transmit to the second storage unit 11. The second storage unit 11 stores a management number, first specifying information, permission information (permission command information), debiter information, a lending period, and the like.
Next, processing after the rental work machine is determined will be described. The processing after the rental work machine is determined is not limited to the following embodiment.

First, the working machine 4 will be described in detail.
FIG. 5 shows a backhoe which is an example of the work machine 4.
As shown in FIG. 5, the backhoe 4 includes a lower traveling device 40 and an upper body 41.
The traveling device 40 has a traveling body 42 having a rubber cover. A crawler type traveling device is adopted in which the traveling body 42 is driven by a traveling motor. A dozer 43 is provided at the front of the traveling device 40.

The machine body 41 includes a swivel base 44 and a work device (excavation device) 45. The swivel base 44 is supported on the traveling device 40 via a bearing 58 so as to be pivotable about a swivel axis. The work device 45 is provided at the front portion of the swivel base 44. On the swivel base 44, an engine, a radiator, a driver's seat 46, a fuel tank, a hydraulic oil tank, and the like are provided.
The work device 45 includes a swing bracket 47, a boom 50, an arm 51, and a bucket 52. The swing bracket 47 is supported by the support 48 so as to be swingable about the vertical axis. The swing bracket 47 swings due to the expansion and contraction of the swing cylinder provided in the swivel base 44. The boom 50 is supported by the swing bracket 47 so as to be swingable about the horizontal axis. The boom 50 swings by expansion and contraction of a boom cylinder 54 interposed between the boom 50 and the swing bracket 47. The arm 51 is supported at the tip of the boom 50 so as to be swingable about the horizontal axis. The arm 51 swings due to the expansion and contraction of an arm cylinder 55 interposed between the arm 51 and the boom 50. The bucket 52 is provided at the tip of the arm 51 so that a squeeze / dump operation is possible. The bucket 52 is squeezed and dumped by expansion and contraction of a bucket cylinder 53 interposed between the bucket 52 and the arm 51.

As shown in FIG. 1, the backhoe includes a control device 60 that performs various controls related to driving (operation) of the work machine. The control device 60 performs various controls such as auto idle control (AI control) and flow rate control. In addition, control in working machines, such as a backhoe, is not limited to what is demonstrated below.
The control device 60 includes an operation amount of an operation member (for example, an operation lever 49 and an operation switch shown in FIG. 5) for operating various actuators such as a swing cylinder, a boom cylinder 54, an arm cylinder 55, and a bucket cylinder 53, and from a governor sensor. Various control signals such as a governor angle (a governor position), an operation amount (angle) of an accelerator lever, an on / off signal of an idle switch (AI-SW), and an engine speed from an engine rotation sensor are input.

In the AI control, when an operation member for operating the arm 51 (arm cylinder 55), the boom 50 (boom cylinder 54) or the like is operated, the engine speed is increased / decreased according to the operation amount of the accelerator lever. When is not being operated, the engine speed is fixed to the idling state.
Specifically, in the AI control by the control device 60, when an idle switch ON signal is input with the operation lever 49 in the neutral position, an idle signal is output to the auto idle motor regardless of the operation amount of the accelerator lever. The auto idle motor is driven to set the engine speed to the idle speed. In the AI control by the control device 60, when an idle switch OFF signal is input by swinging the operation lever 49 back and forth or left and right, an operation signal is output to the auto idle motor based on the accelerator position signal. Drive. When the auto idle motor is driven, the governor lever is actuated and the engine speed becomes the speed corresponding to the accelerator lever.

In the flow rate control, the actuator is operated according to the operation amount of the operation member.
In the flow rate control by the control device 60, for example, when the operation lever 49 is swung from the neutral position, a current (actuated) of a predetermined value corresponding to the operation amount of the operation lever 49 is applied to the solenoid of the electromagnetic proportional valve provided in the work implement. Signal). Then, the electromagnetic proportional valve opens according to the current value (operation amount), the pilot pressure of the control valve corresponding to the actuator is controlled, and the actuator operates.

  The control device 60 includes a fourth storage unit 61 and a third communication unit 64. The fourth storage unit 61 is configured by a non-volatile memory or the like, stores identification information (third identification information) of the work implement, and stores determination information corresponding to the third identification information. The determination information is used for determination when control is performed by the control device 60, as will be described later. For example, the determination information is the same information as the permission command information issued by the issuing unit 22. The third specifying information and the determination information are written in the fourth storage unit 61 when the work machine 4 is manufactured or when the work machine 4 is sold.

The third communication unit 64 can communicate various information. The third communication unit 64 is a device that performs wireless communication such as WiFi (R), Bluetooth (R), and ZigBee (R), for example. Note that the third communication unit 64 may be a communication device that can be connected to a mobile phone communication network.
As shown in FIG. 1, the operating system of the work machine includes a control device 60, a command device 30, and a writing device 31. The command device 30 is a device capable of storing command information and measuring time (time). That is, the command device 30 has a calculation unit (processing unit) such as a CPU that can measure at least the time and perform a predetermined process, and is, for example, a tag or an IC card having a CPU. Note that the command device 30 is a device different from an RFID or the like that does not have a calculation unit such as a CPU. The command device 30 is a device that can communicate with the third communication unit 64.

  The writing device 31 can be connected to the first management server 2 or the second management server 3 through a network. For example, rental information including permission command information can be acquired through the network. When the rental information of a predetermined work machine (rental work machine) is acquired from the first management server 2 and connected to the command device 30, the writing device 31 writes the rental information into the command device 30.

For example, when the writing device 31 acquires the rental information of the rental work machine whose first specific information is “K-RX253200”, the writing device 31 indicates “K-RX253200” indicating the first specific information, the lending period (9 / 1˜ 9/25), “015501-389761” indicating permission command information is written in the command device 30.
The command device 30 includes an acquisition unit 32, a time calculation unit (timer unit) 33, a fourth communication unit 34, and a processing unit (second processing unit) 35. The command device 30 includes an acquisition unit 32, a time calculation unit (timer unit) 33, a fourth communication unit 34, and a second processing unit 35, which are configured by electric / electronic components, programs, and the like incorporated in the command device 30. . The second processing unit 35 is configured by a CPU or the like.

  The acquisition unit 32 acquires rental information including a lending period (expiration date), and acquires rental information by writing by the writing device 31. For example, the writing device 31 gives the command device 30 the first specific information indicated by “K-RX253200”, the lending period indicated by “9/1 to 9/25”, and the permission command information (permission information). When written, the acquisition unit 32 acquires “K-RX253200”, “9/1 to 9/25”, permission command information, and the like.

The acquisition unit 32 acquires the rental information transmitted from the first communication unit 13 of the first management server 2 via the fourth communication unit 34 instead of acquiring the rental information via the writing device 31. May be. The time calculation unit 33 is a timer for obtaining the current time.
The fourth communication unit 34 can communicate various information. The fourth communication unit 34 is a device that performs short-range wireless communication or short-range wireless communication such as IWiFi (R), Bluetooth (R), and ZigBee (R), for example.

  When the fourth communication unit 34 of the command device 30 and the third communication unit 64 of the control device 60 enter the communicable range (within the communication area), the command device 30 notifies the control device 60 of the third specific information and the determination information. Make a request. Thereafter, the command device 30 acquires the third specifying information transmitted from the control device 60. Then, the second processing unit 35 authenticates the third specific information and the first specific information, and authenticates the determination information and the permission command information when the third specific information matches the first specific information. When authentication of the determination information and the permission command information is established (the determination information and the permission command information match), the second processing unit 35 determines whether or not the current time (time) is within the lending period. That is, it is determined whether or not the current time has reached the expiration date.

For example, the second processing unit 35 refers to the current time (time) obtained by the time calculation unit 33 when the specific information matches (authentication establishment) and the permission information matches (authorization information authentication establishment). Then, it is determined whether or not the current time is within the lending period. That is, based on the time obtained by the time calculation unit 33, it is determined whether or not the current time has reached the expiration date.
The expiration date is the last day of the lending period and does not exceed the last day. For example, if the lending period is 9/1 to 9/25, “9 / 25,23: 59: 59 "is the expiration date.

  If the current time has not reached the expiration date, the second processing unit 35 determines that control by the control device 60 is not restricted. If the second processing unit 35 determines not to limit the control, the fourth communication unit 34 outputs a permission command (second command) not to limit the control to the control device 60. When the control device 60 acquires the permission command (second command) transmitted from the command device 30 (fourth communication unit 34), the control device 60 performs control as usual without restricting the control of the traveling system and the working system.

  On the other hand, the second processing unit 35 limits the control by the control device 60 when the current time (time) obtained by the time calculating unit 33 exceeds the lending period, that is, when the current time reaches the expiration date. Judge to do. When the second processing unit 35 determines that the control device 60 restricts the control, the fourth communication unit 34 outputs a restriction command (first command) for restricting the control to the control device 60. When the control device 60 obtains the restriction command (first command) transmitted from the command device 30 (fourth communication unit 34), the control device 60 restricts control of the traveling system and the working system. For example, the control device 60 limits the normal control of the work machine 4 so as not to perform AI control or flow rate control. That is, when the control of the control device 60 is restricted, the work machine 4 cannot perform normal control, and the operation of the work machine 4 can be stopped.

In the above-described embodiment, the work machine 4 cannot be moved when the lending period expires (the expiration date expires), but in addition to this, the lending period may be extended. A modification of extending the lending period will be described.
The first processing unit 12 of the management server 2 is able to lend the work machine desired by the debiter even after the lending period has elapsed (when it can be estimated that lending can be continued after the lending period). The first processing unit 12 sets in advance an extension period that is continuous to the lending period within a range in which lending is possible. For example, if the lending period is 9/1 to 9/25 and the lending period is 10 days, the extension period is set to 9/26 to 10/5.

  The first processing unit 12 issues an extended period associated with permission information (permission command information). The second storage unit 11 stores an extension period associated with the permission information separately from the lending period. Further, the extension period associated with the permission information is transmitted from the first management server 2 simultaneously with the command device 30 when the command device 30 (writing device 31) acquires the rental information, that is, when the permission command information is acquired. It is transmitted to (writing device 31).

  The acquisition unit 32 of the command device 30 can acquire the extended period associated with the permission information. When the writing device 31 writes the extension period associated with the permission information to the command device 30, the acquisition unit 32 acquires the written extension period. The command device 30 is provided with a switch. When the switch is pressed in a state where the permission information matches the determination information and the extension period associated with the permission information is held in the command device 30, the second processing unit 35 of the command device 30 Allow use of extended period. That is, the second processing unit 35 extends the expiration date to the last day of the extension period.

  Note that the first processing unit 12 may issue a code (permission code) different from the permission information, apart from the extension period. In this case, the second storage unit 11 stores an extension period and a permission code separately from the lending period. Further, the extension period and the code are obtained from the first management server 2 at the same time when the command device 30 (writing device 31) acquires rental information, that is, when permission command information is acquired. Sent to.

  The acquisition unit 32 of the command device 30 can acquire the extension period and the permission code. When the writing device 31 writes the extension period and the permission code to the command device 30, the acquisition unit 32 acquires the written extension period and the permission code. On the other hand, a code (external code) can be input to the display device or the like mounted on the work machine 4. When a switch or the like provided in the commanding device 30 is turned on, the second processing unit 35 of the commanding device 30 requests the control device 60 for an external code. On the other hand, when an external code is input to the display device or the like after requesting the external code from the command device 30, the control device 60 transmits the external code to the command device 30. When the external code transmitted from the control device 60 matches the permission code, the second processing unit 35 of the command device 30 permits the use of the extended period. That is, the second processing unit 35 extends the expiration date to the last day of the extension period.

In this way, after the rental of the work equipment 4 is started, the extension period is written in the command device 30, so that when the user wishes to extend, the command device 30 is connected to the first management server 2. Even without it, you can easily extend the expiration date offline.
The writing device 31 has written permission command information (permission information) indicated by numbers or the like to the command device 30, but instead of writing “015501-389761” indicated by numbers or the like to the command device 30 During the period (9 / 1-9 / 25), a flag indicating that the rental work machine whose first specific information is “K-RX253200” is permitted to be rented (even if the normal control is performed without restriction) Information may be written to the command device 30. In this case, when the current time has not reached the expiration date and the permission information has been acquired, the command device 30 determines that the control device 60 does not restrict the control. On the other hand, the command device 30 restricts the control by the control device 60 when the permission information cannot be acquired even if the current time has not reached the expiration date.

  As described above, by linking the first management server 2 owned by the rental company and the second management server 3 owned by the manufacturer, the management of the work machine 4 by the rental company can be simplified. For example, since the manufacturer gives permission for rental and permission command information (permission information) for driving the work machine 4 is issued by the manufacturer, the rental company drives a number of work machines 4 owned by the rental company. Can be saved the trouble of managing the key (permission information). That is, by using information (work machine information) managed by the manufacturer at the time of manufacture or sale, a key for operating the rental work machine can be easily generated and provided to the rental company.

In addition, since the first management server 2 owned by the rental company and the second management server 3 owned by the manufacturer are linked, information sharing between the rental company and the manufacturer can be performed, and the rental of the work machine 4 can be performed smoothly. It can be carried out.
In addition, since the command device 30 has the authority to measure the time and what kind of control the control device 60 performs, the command device 30 controls the work device 4 when the lending period has elapsed. The work implement 4 can be stopped without making a determination at 60. That is, it is not necessary to provide a timing unit for the control device 60 or a determination unit for determining whether or not the expiration date has come.
[Second Embodiment]
FIG. 4 shows another work machine rental system.

The work machine rental system shown in FIG. 4 is a system in which the second management server 3 is eliminated and the first management server 2 issues permission command information (permission information). The description of the same configuration as the above-described embodiment is omitted.
The first management server 2 includes an issuing unit 23. The issuing unit 23 includes electrical / electronic components, programs, and the like incorporated in the first management server 2. After determining that the work machine desired by the first processing unit 12 can be rented, the issuing unit 23 recognizes that the work machine that has been lent is authorized as a rental work machine that permits rental. The command information (permission command information) indicated is issued. After issuing the permission command information, the first processing unit 12 notifies the communication device 5 of information indicating that the rental reservation has been completed, assuming that the work machine desired by the debiter can be rented. In addition, the first processing unit 12 and the second storage unit 11 perform a process of updating information in the second storage unit 11. The first processing unit 12 sets the management number, the management number, the first specific information of the work machine (rental work machine) for which the rental permission has been granted, the permission information (permission command information), the debiter information, the lending period, etc. The data is transmitted to the storage unit 11. The second storage unit 11 stores a management number, first specifying information, permission information (permission command information), debiter information, a lending period, and the like.

  When renting a work machine, the writing device 31 is connected to the first management server 2 through a network, and acquires rental information including permission command information through the network. Then, when the command device 30 is connected to the writing device 31, rental information such as the first specifying information of the rental work machine, the rental period, and the permission command information is written in the command device 30. The command device 30 in the second embodiment is the same as that in the above-described embodiment.

As described above, since the command device 30 has the authority to measure the time and what kind of control is performed in the control device 60, the command device 30 allows the work machine 4 to be used when the lending period has elapsed. The work machine 4 can be stopped without making a determination to the control device 60.
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 embodiment described above, the second management server 3 issues permission command information corresponding to work machine specific information, while the control device 60 stores in advance determination information corresponding to work machine specific information. By doing so, in the work machine having the same specific information, the permission command information and the determination information match, and the normal control by the control device 60 can be performed without restriction. Instead of this, the control device 60 may be configured to perform normal control by the control device 60 without limitation without storing the determination information.

  In this case, the first specifying information is encrypted using the permission command information issued by the issuing unit 22 of the second management server 3. Then, the second management server 3 transmits the encrypted first identification information, the unencrypted first identification information, and the permission command information to the first management server 2. The writing device 31 writes the encrypted first specific information, permission command information, and lending time limit to the command device 30. In the command device 30, the second processing unit 35 restores the first specific information encrypted by using the encrypted first specific information and the permission command information, the third specific information, and the first specific information after the restoration. It is determined whether or not the information matches. Also in this case, it is possible to determine whether or not the permission command information is valid without writing the determination information in the control device 60.

  In the embodiment described above, the control device 60 does not perform AI control or flow rate control as a control restriction. However, the control device 60 is not limited to this as a matter of course. For example, the engine speed is fixed at a low speed, The work machine 4 may be prevented from moving normally by stopping the start itself (prohibiting engine start) or restricting various other controls.

  In the embodiment described above, the rental information including the permission command information (permission signal) transmitted from the first management server 2 is written in the command device 30, but the rental information is obtained from the first management server 2. It does not have to be. For example, the command device 30 may be connected to a personal computer or the like, information corresponding to rental information may be created by the personal computer, and the created rental information may be written into the command device 30.
