A working device 9 such as a fertilizer spraying device, a plowing device, a pesticide spraying device, a sowing spraying device, and a harvesting device is detachably attached to the three-point link mechanism 5. In this embodiment, as shown in FIG. 16, the fertilizer application device is attached to the three-point link mechanism 5.

  As shown in FIG. 1, the control device 20 and the data communication device 30 are connected by a vehicle communication network (for example, Controller Area Network, FlexRay, etc.) N1. The control device 20 performs traveling system control, working system control, and the like of the tractor 1, and controls the operation of the engine as traveling system control or operation provided around the driver's seat as working system control. When an input from an operation tool such as a lever or an operation switch is received, operations such as raising and lowering of the three-point link mechanism 5 and output (rotation speed) of the PTO shaft are controlled according to the input value. Control signals for performing traveling system control and work system control of the tractor 1 and various detection signals for performing control (for example, signals detected by the sensors) are output to the vehicle communication network, and are transmitted to each part of the tractor 1. Communicated. The travel system control and work system control by the control device 20 are not limited to those described above.

  The data communication device 30 acquires various data relating to the tractor via the vehicle communication network N1, for example, various signals output to the vehicle communication network N1 (detection signals and control detected by various sensors). For example, a control signal for performing a warning, a warning signal indicating an abnormality, etc.). The data communication device 30 connects the tractor-side network (vehicle communication network N1) and a network outside the tractor (for example, a wide area network) in order to output various acquired data to the outside. It is something that can be done.

For example, in order to execute transmission / reception of data between onboard devices such as the control device 20 and the data communication device 30 belonging to the vehicle communication network N1 and the portable terminal 40a belonging to the wide area network, the data communication device 30 Conversion of communication protocols of different networks and various communication processes are performed.
The data communication device 30 includes a communication processing unit 32 that performs various communication processes. The communication processing unit 32 performs short-range wireless communication processing such as Wi-Fi (registered trademark). In this embodiment, the communication processing unit 32 performs processing for performing wireless communication using Wi-Fi (Wireless Fidelity, registered trademark) corresponding to the IEEE 802.11 series which is a communication standard.

On the other hand, the mobile terminal 40a is, for example, a portable computer such as a smart phone (multifunctional mobile phone) or a tablet PC having a relatively high computing capability. The portable terminal 40a performs short-range wireless communication such as Wi-Fi (registered trademark). The portable terminal 40a includes a communication unit (communication processing unit 41) that performs processing related to communication.
The first management server 50a mainly manages permission keys that permit authentication (pairing) between the data communication device 30 and the portable terminal 40a.

As shown in FIG. 2, in order to perform pairing between the data communication device 30 and the mobile terminal 40a, first, mobile terminal specifying information for specifying the mobile terminal 40a is transmitted from the mobile terminal 40a to the first management server 50a. At the same time, work implement specifying information for specifying the work implement associated with the data communication device 30 to be paired is transmitted (first step).
Next, the first management server 50a uses the first permission key based on the portable terminal identification information and work implement identification information output from the portable terminal 40a and the information registered in the user management database 60 of the first management server 50a. Is determined to be output to the portable terminal 40a (second step).

When the first management server 50a permits the output of the first permission key to the portable terminal 40a, the first permission key is output from the first management server 50a to the portable terminal 40a (third step).
When the portable terminal 40a acquires the first permission key from the first management server 50a, the portable terminal 40a outputs the first permission key to the data communication device 30 (fourth step). When the data communication device 30 receives the first permission key, the data communication device 30 performs authentication between the permission key (first permission key) stored in advance in the data communication device 30 and the first permission key. Is determined (fifth step).

When the validity of the first permission key is recognized, the data communication device 30 permits (outputs) data from the data communication device 30 to the portable terminal 40a (pairing is established), and the data communication device 30 Data can be transmitted to the portable terminal 40a.
Thus, the process from the first step to the fifth step, that is, the process between the portable terminal 40a and the first management server 50a, and the process between the portable terminal 40a and the data communication device 30 are performed. By passing, pairing with the data communication apparatus 30 and the portable terminal 40a can be performed.

  In addition, when performing pairing with the data communication apparatus 30 and the portable terminal 40a, the portable terminal 40a acquires the 1st permission key by transmitting portable terminal specific information and work machine specific information to the 1st management server 50a. However, if pairing has been established with the first permission key even once, the mobile terminal specifying information and work implement specifying information are sent from the mobile terminal 40a to the first management server after the second time. Pairing may be performed by transmitting the already acquired first permission key to the data communication device 30 without transmitting to 50a.

First, the first management server 50a will be described in detail.
The user management database 60 included in the first management server 50a stores information on work machines owned by the user (user), information on portable terminals owned by the user, and information on the user.
The information about the work machine, the information about the portable terminal, and the information about the user are obtained when the user purchases the work machine from the sales company or the like together with the data communication apparatus 30 or after the user purchases the work machine. It is stored (registered) when purchased separately.

For example, when the user purchases a work machine (such as a tractor) and the data communication device 30, FIG.
As shown in FIG. 4, the user's address, name, password, user ID, and the like are registered (stored) in the user management database 60 as information about the user. The user's address, name, password, and user ID are user identification information. The user specifying information may be any information for identifying the user.

Further, the user management database 60 stores the telephone number of the mobile terminal 40a owned by the user as information on the mobile terminal. The telephone number is mobile terminal specifying information for specifying the mobile terminal 40a. The mobile terminal specifying information may be any information as long as it is unique for identifying the mobile terminal 40a.
Further, as information on the work machine, there are a tractor manufacturing number and model for identifying the tractor 1 purchased by the user, a manufacturing number for identifying the control device 20, a manufacturing number for identifying the data communication device 30, and the like. be registered. The tractor manufacturing number and model, the control device 20 manufacturing number, and the data communication device 30 manufacturing number are work machine specifying information for specifying the work machine side. The work implement specifying information may be any information as long as it is unique for identifying the tractor 1, the control device 20, and the data communication device 30.

  Thereafter, the mobile terminal specifying information and work implement specifying information stored in the user management database 60 are stored in the user management database 60 in order to distinguish the mobile terminal specifying information and work implement specifying information output from the mobile terminal 40a. The portable terminal specifying information is referred to as “stored portable information”, the work machine specifying information stored in the user management database 60 is referred to as “stored work machine information”, and the portable terminal specifying information output from the portable terminal 40a. The information is referred to as “output portable information”, and the work machine specifying information output from the portable terminal 40a is referred to as “output work machine information”.

A method for registering various types of information (information related to work machines, information related to portable terminals, and information related to users) in the user management database 60 mainly uses a computer installed by a sales company or the like at the time of sales of the work machine. There are a first method for registration and a second method for a user to access and register the first management server 50a directly after purchasing the work implement.
As described above, in any of the first method and the second method, when various types of information are input to the first management server 50a, the registration unit 52 provided in the first management server 50a registers the various types of information. Done. The registration unit 52 includes a program stored in the first management server 50a.

  Specifically, the manufacturing number and model of the tractor, the manufacturing number of the control device 20, the manufacturing number of the data communication device 30, the telephone number, address, name, etc. of the mobile terminal are transmitted to the first management server 50a and the first When input to the management server 50a, the registration unit 52 associates the manufacture number and model of the tractor, the manufacture number of the control device 20, the manufacture number of the data communication device 30, the telephone number of the mobile terminal, the address, and the name, respectively. These are stored (registered) in the user management database 60.

Also, when the registration unit 52 has enough information to associate the mobile terminal 40a with the data communication device 30 (tractor), the registration unit 52 issues a first permission key used for pairing, and uses the first permission key. And stored in the user management database 60 in association with various information.
For example, portable terminal identification information (for example, a telephone number) of the portable terminal 40a owned by the user, and work machine identification information for identifying the work machine owned by the user (the tractor serial number and model, the manufacture of the control device 20) Registration number 52 issues a first permission key corresponding to the portable terminal identification information and the work implement identification information. Then, the first permission key, the portable terminal identification information, and the work machine identification information are associated and registered in the user management database 60. In addition to the portable terminal identification information and the work machine identification information, the registration unit 52 issues the first permission key when information related to the user and a user ID or password is input to the first management server 50a. May be performed.

As shown in FIG. 1, whether or not the first permission key can be output to the portable terminal 40 a owned by the user is determined by a user registration determination unit 53 provided in the first management server 50. The user registration determination unit 53 includes a program stored in the first management server 50a.
For example, when the user performs farm work in the field using a work machine (tractor), when the output portable information and work machine specifying information are output from the mobile terminal 40a owned by the user to the first management server 50a, the user registration determination First, the unit 53 determines whether the output portable information output from the portable terminal 40a and the output work machine information output from the portable terminal 40a are associated with each other and stored in the user management database 60. .

As shown in FIG. 3, in the state where various types of information are registered in the user management database 60, for example, “012-9354-2973” is output to the first management server 50a as output portable information, and output work machine information is output. It is assumed that “10013 (manufactured tractor number, M115A (tractor model)”) is output to the first management server 50a.
In this case, the output portable information “012-9354-2973” and the output work machine information “10013, M115A” are stored in the user management database 60 in association with each other. 53 permits the output of the first permission key corresponding to “012-9354-2973” and “10013, M135A”.

As shown in FIG. 1, the first permission key is output to the portable terminal 40 a owned by the user by a permission information output unit 54 provided in the first management server 50. The permission information output unit 54 includes a program stored in the first management server 50a.
When the user registration determination unit 53 permits the output of the first permission key, the permission information output unit 54 reads the first permission key corresponding to the output portable information and the output work machine information from the user management database 60, and The permission key is output to the portable terminal 40a. The permission information output unit 54 does not output the first permission key when the user registration determination unit 53 determines not to output the first permission key.

Next, the mobile terminal 40a will be described.
The portable terminal 40 a includes a machine information request unit 43, an information output unit 44, and a permission key output unit 45. The machine information request unit 43, the information output unit 44, and the permission key output unit 45 are configured by a program stored in the mobile terminal 40a.
The machine information request unit 43 requests the data communication device 30 for work implement specifying information stored in advance in the data communication device 30 when performing pairing between the portable terminal 40a and the data communication device 30. is there.

When the information output unit 44 acquires the first permission key from the first management server 50a, the information output unit 44 transmits the portable terminal specifying information, the work implement specifying information acquired by the machine information requesting unit 43, and the like to the first management server 50a. It is.
For example, when performing pairing, when a program for pairing of the mobile terminal 40a is started and a user ID or password is input to the mobile terminal 40a, the information output unit 44 receives the input user ID and password. Output to the first management server 50a. Moreover, when login with the 1st management server 50a and the portable terminal 40a is permitted with a user ID and a password, it acquired automatically from the portable terminal specific information stored in the portable terminal 40a, or the data communication apparatus 30 beforehand. The work machine specifying information is output to the first management server 50a.

Further, the mobile terminal 40 a includes a permission key output unit 45. The permission key output unit 45 includes a program stored in the mobile terminal 40a.
When the portable terminal 40a acquires the first permission key from the first management server 50a, the portable terminal 40a stores the first permission key. The permission key output unit 45 transmits the first permission key stored in the portable terminal 40 a to the data communication device 30 when performing pairing.

The permission key output unit 45 is output from the first management server 50a when performing pairing between the mobile terminal 40a and the data communication device 30 after acquiring the first permission key output from the first management server 50a. The first permission key is output to the data communication device 30.
Next, a configuration related to pairing in the data communication apparatus 30 will be described.
The data communication device 30 stores a first permission key necessary for pairing the data communication device 30 and the portable terminal 40a. The first permission key stored in the data communication device 30 is stored in advance when the data communication device 30 is manufactured.

In addition, the communication processing unit 32 of the data communication device 30 includes a communication permission unit 37. The communication permission unit 37 includes a program stored in the data communication device 30.
When receiving the first permission key output from the portable terminal 40a, the communication permission unit 37 authenticates with the first permission key stored in the data communication device 30 in advance, and transmits the first permission key transmitted from the portable terminal 40a. Determine the validity of the key. And the communication permission part 37 permits the pairing between the data communication apparatus 30 and the portable terminal 40a, when the validity of the permission key output from the portable terminal 40a is recognized. That is, the communication permission unit 37 permits the data collected by the data communication device 30 to be transmitted to the portable terminal 40a, and transmits the collected data to the portable terminal 40a to the portable terminal 40a. On the other hand, when the validity of the first permission key is not recognized, the communication permission unit 37 does not permit the data transmission from the data communication device 30 to the portable terminal 40a.

FIG. 4 summarizes the operations of the data communication device, the portable terminal, and the first management server. Based on FIG. 4, the operation of the data communication system 10a of the work machine will be described.
Before the data communication device 30 and the mobile terminal 40a are paired, information (user ID and password) for the user to log in to the first management server 50a is registered in the user management database 60. Further, before performing pairing, the work machine identification information owned by the user and the portable terminal identification information owned by the user are registered in the user management database 60.

When performing pairing between the data communication device 30 and the portable terminal 40a, as a first step, the network key stored in the portable terminal 40a is automatically output from the portable terminal 40a to the data communication device 30. (Step S100).
When the data communication device 30 receives the network key, the data communication device 30 authenticates the network key set in advance to the network key transmitted from the portable terminal 40a (step S101).

  The network key authentication performed between the data communication device 30 and the portable terminal 40a is performed in advance for pairing between the data communication device 30 and the portable terminal 40a. When authentication is established, wireless communication is established between the data communication device 30 and the portable terminal 40a. In a state where wireless communication with the network key is established, wireless communication can be performed between the data communication device 30 and the portable terminal 40a, but data collected by the data communication device 30 is not sent to the portable terminal 40a. Yes. Specifically, when the authentication by the network key is established, the machine information requesting unit 43 of the portable terminal 40a can request the work machine specifying information from the data communication device 30.

The portable terminal 40a requests the work machine specifying information stored in the data communication device 30 by the machine information request unit 43 (step S102).
When receiving a request for work implement specifying information from the portable terminal 40a, the data communication device 30 outputs the work implement specifying information to the portable terminal 40a (step S103). When the portable terminal 40a acquires the work implement specifying information, the portable terminal 40a stores the work implement specifying information.

Next, when a user ID or password is input to the mobile terminal 40a, the information output unit 44 outputs the user ID and password to the first management server 50a (step S200).
When the user ID and password output from the mobile terminal 40a are associated and stored in the user management database 60, the first management server 50a permits the login of the mobile terminal 40a (step S201). The first management server 50a makes a request for portable terminal specifying information and work implement specifying information for the portable terminal 40a permitted to log in (step S202). The information output unit 44 of the portable terminal 40a receives the request for the portable terminal identification information and the request for the work implement identification information from the first management server 50a, and sends the portable terminal identification information (output portable information) to the first management server. The work machine specifying information (output work machine information) acquired from the data communication device 30 is output to the first management server 50a (step S203).

  When the output portable information and the output work machine information are input to the first management server 50a, the user registration determination unit 53 of the first management server 50a includes the output portable information in the stored portable information stored in the user management database 60. It is determined whether there is stored portable information that matches the information, and whether there is stored work machine information that matches the output work machine information (step S204).

In addition, the user registration determination unit 53 of the first management server 50a includes the user management database 60.
If the stored portable information that matches the output portable information exists and the stored work machine information matches the output work machine information, the stored portable information and the storage work machine information are associated with each other. It is determined whether or not the process has been performed (step S205).
When the stored portable information and the stored work machine information are associated with each other, the user registration determination unit 53 grants permission key output to the portable terminal 40a corresponding to the output portable information (step S206). The permission information output unit 54 receives the output permission from the user registration determination unit 53, and outputs the first permission key to the portable terminal 40a (step S207).

When receiving the first permission key transmitted from the first management server 50a, the permission key output unit 45 of the portable terminal 40a transmits the first permission key to the data communication device 30 (step S208).
When the data communication device 30 receives the first permission key, the communication permission unit 37 of the data communication device 30 reads the first permission key stored in itself and authenticates with the received first permission key ( Step S209). When the authentication of the first permission key is established (when the validity of the first permission key is recognized), the communication permission unit 37 allows the data acquired by the data communication device 30 to be output to the mobile terminal 40a (step). S210). When transmission of data to the data communication device 30 is permitted, the data communication device 30 transmits data to the portable terminal 40a (step S211). Note that when the data communication device 30 and the mobile terminal 40a have been paired with the first permission key in the past, the above-described steps S200 to S207 are omitted in the second and subsequent pairings. In this case, when a program for executing pairing is started, the first permission key output unit 45 of the portable terminal 40a outputs the first permission key stored in the portable terminal 40a to the data communication device 30, The data communication device 30 authenticates whether or not to perform pairing using the first permission key transmitted from the mobile terminal 40a.

  As described above, according to the present invention, the portable terminal identification information and the work machine identification information are output to the first management server 50a, and the portable terminal identification information and the work machine identification information are stored in the user management database 60. Since the first permission key for pairing is output based on the terminal identification information and the work machine identification information, it is sold in order to acquire data from the data communication device 30 (work machine). The work machine and the portable terminal 40a linked to the work machine are registered in the user management database 60, and at the time of data acquisition, the registration of the work machine and the portable terminal 40a is proved from the first management server 50a. It is necessary to have you do. As described above, in order to acquire data from the work machine, since the data is acquired after the registration between the portable terminal 40a and the data communication device 30 (work machine) is performed, illegal data acquisition is performed. In addition, the reliability of acquired data can be improved.

In recent years, there is a desire to acquire work data during farm work when performing farm work on a farm field. However, in the conventional system, a method for acquiring work data when performing farm work safely and appropriately has not been constructed.
For example, when the user purchases an agricultural machine such as a tractor and the data communication device 30 attached to the agricultural machine, the user identification information, the work machine identification information, and the portable terminal identification information are registered in the user management database 60. Keep it. And when performing farm work using a tractor, after logging in to the 1st management server 50a using a personal digital assistant 40a which a user owns, the 1st permission key acquired from the 1st management server 50a is used. Thus, pairing between the mobile terminal 40a and the data communication device 30 is established. Since data is transmitted from the data communication device 30 to the portable terminal 40a after pairing is established, it becomes possible to save (store) the information on the tractor when the farm work is performed in the portable terminal 40a. .

As can be seen from this, it is possible to acquire work data during farm work only by combining the portable terminal 40a owned by the user and the agricultural machine (data communication device 30) on which the user performs farm work. A data structure in which three users, the user who operates the agricultural machine and the agricultural machine, are associated with each other can be used. The user transmits work data at the time of farm work stored in the mobile terminal 40a to, for example, a computer different from the mobile terminal 40a, and organizes the work data using the computer, for example, a work plan for each farm field. And can be used for work reports. In particular, in the present invention, since the correspondence relationship between the agricultural machine that actually moved when the data was acquired and the mobile terminal (the operator who moved the agricultural machine) that acquired the data is clear, If it is operated, it is possible to analyze whether the yield in the field can be improved according to the actual situation.

  In the embodiment described above, when the output management information (stored mobile information) and the output work machine information (storage work machine information) are already associated in the user management database 60, the first permission key is issued and output. Although it has been performed, the first permission key may be issued and output even when the output portable information and the output work machine information are not associated with each other when the output portable information and the output work machine information are input to the first management server 50a. In other words, registration of the output portable information and output work machine information in the user management database 60, and the issuance and output of the first permission key may be performed simultaneously.

  FIG. 5 shows a data communication system 10b of the work machine in the first modification (first modification). The registration unit 52 of the first management server 50b shown in FIG. 5 has already been output when mobile specific information (output mobile information) or work implement specific information (output work implement information) is output from the mobile terminal 40b to the management server 50b. Unless the output portable information and the output work machine information are stored in association with each other, the output portable information and the output work machine information are stored in the user management database 60 in association with each other.

In addition, the registration unit 52 stores the output portable information and the output work machine information in the user management database 60, and at the same time, issues a first permission key corresponding to the output portable information and the output work machine information. The permission key is stored in the user management database 60.
Upon receiving the first permission key issued by the registration unit 52 (when the first permission key is issued by the registration unit 52), the user registration determination unit 53 receives the output portable information and the output work machine information. It is determined that they are associated. When the user registration determination unit 53 determines that the association is performed, the permission information output unit 54 assigns the first permission key corresponding to the output portable information that is determined to be associated to the user management database 60. The first permission key is output to the portable terminal 40b. That is, when the first permission key is issued by the registration unit 52, the first permission key is output.

FIG. 6 summarizes the operations of the data communication device, the portable terminal, and the management server in the work machine data communication system 10b. Description of the same operation is omitted.
After permitting login to the first management server 50b, the management server 50b makes a request for portable terminal identification information and a work machine identification information of the portable terminal 40b permitted to log in (step S400). The information output unit 44 of the mobile terminal 40b receives the request for the mobile terminal specifying information and the request for the work implement specifying information from the first management server 50b, and sends the mobile terminal specifying information (output mobile information) to the first management server. The work machine identification information (output work machine information) acquired from the data communication device 30 is output to the first management server 50b (step S401).

When the output portable information and the output work machine information are input to the first management server 50b, the registration unit 52 of the first management server 50b adds the output portable information to the stored portable information stored in the user management database 60. It is determined whether or not there is stored portable information that matches, and it is determined whether or not there is stored work machine information that matches the output work machine information (step S402).
In addition, the registration unit 52 of the first management server 50b stores the stored portable information that matches the output portable information in the stored portable information stored in the user management database 60 and matches the output work machine information. If there is machine information, it is determined whether or not the stored portable information and the storage work machine information are associated (step S403).

Here, when the storage portable information and the storage work machine information are associated, since the output portable information and the output work machine information are already associated, the registration unit 52 of the first management server 50b Without issuing the first permission key, the process proceeds to the user registration determination unit 53, and the user registration determination unit 53 determines that the association has been made.
On the other hand, when the storage portable information and the storage work machine information are not associated with each other, the registration unit 52 of the first management server 50b associates the output portable information with the output work machine information (step S404). Is stored in the user management database 60, and the first permission key corresponding to the output portable information and the work machine specifying information is issued (step S405).

For example, as shown in FIG. 7A, it is assumed that stored portable information and stored work machine information are stored in the user management database 60. Here, “012-9354-2973” is output from the portable terminal 40b as output portable information to the management server 50b, and “20891 (Tractor serial number, M115A (tractor model)” is output as the management information on the management server 50b. Is output.
Looking in the user management database 60 (FIG. 7A), “012-9354-2973” which is output portable information output from the portable terminal 40b and “20891, M115A” which is output work machine information are Although already stored in the user management database 60, “012-9354-2973” is associated with “10013, M115A”, which is another storage work machine information.

That is, the output portable information (“012-9354-2973”) output from the portable terminal 40 b and the output work machine information (“20891, M115A”) are not associated with each other in the user management database 60.
Therefore, as illustrated in FIG. 7B, the registration unit 52 of the management server 50b associates “012-9354-2973” that is the output portable information with “20891, M115A” that is the output work machine information. The first permission key corresponding to these is issued while being stored in the user management database 60.

  When the first permission key is issued by the registration unit 52, the permission information output unit 54 associates the output portable information “012-9354-2973” with the output work machine information “20891, M115A” at the time of registration. Therefore, the first permission key is output (step S406). Authentication and the like for determining the validity of the first permission key are the same as in steps S208 to S210, and thus description thereof is omitted.

In the case of FIG.6 and FIG.7, since registration with permission authentication information (for example, mobile specific information, work machine specific information) can be performed simultaneously with authentication with the portable terminal 40b and the data communication apparatus 30, registration and The operation of obtaining the authorization key for authentication can be simplified.
FIG. 8 shows an overall view of a data communication system 10c for a working machine in a second modification (second modification) obtained by modifying the above-described embodiment. In this work machine data communication system 10c, the data structure of the user management database 60 in the first management servers 50a and 50b, the access method between the portable terminals 40a and 40b and the first management servers 50a and 50b, and the portable terminals 40a and 40b. The storage method of the acquired data is different.

First, the data structure of the user management database 60 in the second modification will be described.
As shown in FIG. 9A, the user management database 60 of the work machine data communication system 10c includes, as information on the work machine, the tractor serial number and model for identifying the tractor 1, and the manufacture of the control device 20. The number, the serial number of the data communication device 30 and the like are registered. The user management database 60 stores at least a machine management code for managing a work machine (tractor) in association with the work machine. This machine management code is unique, and the machine management code indicates a machine (equipment) such as the control device 20 attached to the work machine and the data communication device 30 attached to the work machine in addition to the work machine. It may be for management. Moreover, you may use the working machine specific information mentioned above as a machine management code.

  Further, as shown in FIG. 9B, the user management database 60 stores the user's address, name, password, user ID, etc. as information related to the user, and the mobile phone owned by the user as information related to the mobile terminal. The telephone numbers and the like of the terminals 40a and 40b are stored. The user management database 60 stores at least a user management code for identifying (specifying) a user. In addition to the user, the user management code may be allocated in association with the mobile terminals 40a and 40b owned by the user. In this embodiment, the user management code is uniquely assigned for management separately from the address, name, password, user ID, and mobile number, and is unique.

In this embodiment, the user management database 60 stores a machine management code uniquely assigned to manage the work machine and a user management code uniquely assigned to manage the user.
As shown in FIG. 9C, the user management database 60 has a management data table for extracting a work machine (tractor) and a user who owns the work machine from the machine management code and the user management code. I have. In this management data table, allocated machine management codes and allocated user management codes are arranged in a matrix, and when both codes are known, information on the work machine shown in FIG. (Production number and model of the tractor, production number of the control device 20, production number of the data communication device 30), information (phone number) and user identification information (address, name, Password, user ID) can be extracted.

Next, an access method between the portable terminals 40a and 40b and the first management servers 50a and 50b in the second modification will be described.
In the above-described embodiment, the first management servers 50a and 50b and the portable terminals 40a and 40b are directly accessed. In the second modification, the first management servers 50a and 50b and the portable terminals 40a and 40b are used. Is accessed via a second management server 71 provided separately from the first management servers 50a and 50b.

  Specifically, information (user ID, password, portable terminal identification information, work machine identification information) output (transmitted) to the first management servers 50a and 50b in order for the portable terminals 40a and 40b to obtain the first permission key. Is transmitted to the first management servers 50 a and 50 b via the second management server 71. Further, the first permission key transmitted from the first management server 50 a, 50 b to the portable terminal 40 a, 40 b is also transmitted to the portable terminal 40 a, 40 b via the second management server 71.

  In addition, when the first management server 50a, 50b transmits the first permission key to the portable terminals 40a, 40b via the second management server 71, the portable terminals 40a, 40b that receive the first permission key are: In order to allow access to the second management server 71, a permission key (second permission key) used at the time of authentication as to whether or not access (connection) to the second management server 71 is permitted is assigned to the second management server 71. Via the mobile terminal 40a, 40b. The first management servers 50a and 50b generate a second permission key that is different from the first permission key, such as when the first permission key is issued. This second permission key is different from the user ID and password issued when the user first registered in the first management server 50a, 50b, and the portable terminals 40a, 40b are connected to the first management server 50a, This is for logging in to the second management server 71 which is arranged separately from 50b and whose authority is lower when viewed from the first management servers 50a and 50b. The second permission key is used not only for accessing the second management server 71 but also for connecting to the work machine information database 70 provided in the second management server 71.

  That is, when summarizing the access method between the mobile terminals 40a and 40b and the first management servers 50a and 50b, the mobile terminal information of the mobile terminals 40a and 40b owned by the user, and the work machine identification information of the work machine owned by the user Is received by the first management server 50a, 50b, and the received mobile terminal information and work machine identification information are stored in association with the user management database 60, the first management server 50a, 50b 1 permission key is output to the second management server 71. The first management servers 50 a and 50 b also output a second permission key to the second management server 71.

When the second management server 71 receives the first permission key, the second management server 71 transmits (outputs) the first permission key to the portable terminals 40a and 40b that receive the first permission key, and sends the second permission server to the portable terminals 40a and 40b. The permission key is also transmitted (output).
Now, when transmitting the first permission key to the portable terminals 40a, 40b via the second management server 71, the first management servers 50a, 50b are not only the first permission key but also the user management code and machine management code. Also send. For example, the first management servers 50a and 50b extract, from the user management database 60, the user management code and the machine management code corresponding to the mobile terminal identification information and the work machine identification information associated with the first permission key. Then, the extracted user management code and machine management code are transmitted to the portable terminals 40a and 40b via the second management server 71 together with the first permission key.

Next, a method for storing data acquired by the mobile terminals 40a and 40b will be described.
In the above-described embodiment, the data transmitted from the data communication device 30 is stored in the mobile terminals 40a and 40b. However, in the second modification, the data acquired by the mobile terminals 40a and 40b is the second The work machine information database 70 of the management server 71 is stored.

Specifically, the portable terminals 40a and 40b access (log in) the second management server 71 using the second permission key issued from the first management servers 50a and 50b. If the second permission key transmitted from the portable terminals 40a and 40b is valid, the second management server 71 permits connection of the portable terminals 40a and 40b.
After the login to the second management server 71 is completed (after connection), the portable terminals 40a and 40b transmit the data acquired by the portable terminals 40a and 40b to the work machine information database 70 of the second management server 71. . Further, when the mobile terminals 40 a and 40 b transmit data to the work machine information database 70, the machine management code and the user management code issued from the first management servers 50 a and 50 b are also transmitted to the work machine information database 70.

When the second management server 71 (work machine information database 70) receives data from the portable terminals 40a and 40b, as shown in FIG. 10, the work machine information database 70 includes a user management code, a machine management code, and Information from the portable terminals 40a and 40b is stored in association with the data.
FIG. 11 summarizes the operations of the data communication device, the portable terminal, the first management server, and the second management server in the data communication system 10c of the work machine. FIG. 11 shows the operation (processing) after the first management servers 50a and 50b issue the first permission key. The processing until the first management server 50a, 50b issues the first permission key is performed by the information output from the portable terminals 40a, 40b to the first management server 50a, 50b via the second management server 71. Is the same as the processing from S200 to S405 shown in FIG. That is, in the second modified example, during the exchange between the mobile terminals 40a and 40b and the first management servers 50a and 50b from S200 to S405 shown in FIG. The request for the work machine identification information, the portable terminal identification information, and the transmission of the work machine identification information are not performed directly from the portable terminals 40a and 40b to the first management servers 50a and 50b, but via the second management server 71. Is replaced with the operation up to the issue of the first permission key in the second modification.

As shown in FIG. 11, when the issuance of the first permission key is completed, the first management servers 50a and 50b output the first permission key to the second management server 71 (step S500). When receiving the first permission key, the second management server 71 transmits (outputs) the first permission key to the portable terminals 40a and 40b that receive the first permission key (step S501).
The first management server 50a, 50b also includes a user management code associated with the user who owns the portable terminal 40a, 40b that receives the first permission key, and a machine management code associated with the portable terminal 40a, 40b. (The machine management code associated with the user management code) is transmitted to the second management server 71 (step S502). The second management server 71 transmits the user management code and the machine management code to the portable terminals 40a and 40b (step S503).

  Furthermore, the first management servers 50a and 50b transmit the second permission key to the second management server 71 (step S504). When receiving the second permission key, the second management server 71 stores the second permission key (step S505), and transmits the second permission key to the portable terminals 40a and 40b (step S506). When the first management server 50a, 50b issues the second permission key, instead of storing the second permission key in the second management server 71, the second permission key issued to the first management server 50a, 50b. May be saved. In this case, at the time of authenticating the second permission key, the second management server 71 may make an inquiry about the second permission key to the first management servers 50a and 50b.

When receiving the second permission key and the user management code, the portable terminals 40a and 40b store the received second permission key (step S507) and the user management code (step S508).
Further, when receiving the machine management code, the portable terminals 40a and 40b transmit the machine management code to the data communication device 30 (step S509). When receiving the machine management code, the data communication device 30 stores the machine management code (step S510).

  Next, when storing the data of the portable terminals 40a and 40b in the second management server 71 (work machine information database 70), the portable terminals 40a and 40b perform the second management on the second permission key stored therein. It transmits to the server 71 (step S511). When receiving the second permission key transmitted from the portable terminals 40a and 40b, the second management server 71 determines whether or not the second permission key corresponding to the portable terminals 40a and 40b is stored (Step S512). ), When the second permission key is stored, the second management server 71 permits (connects permission) access to the work machine information database 70 of the portable terminals 40a and 40b (step S513).

  After permitting access to the work machine information database 70 of the portable terminals 40a and 40b (after permitting login), the portable terminals 40a and 40b request a machine management code from the data communication device 30 (step S514). When the machine management code is acquired from the data communication device 30 (step S515), the mobile terminals 40a and 40b store the user management code stored therein, the acquired machine management code, and data to the second management server 71. Transmit (step S516). When the second management server 71 acquires the user management code, the machine management code, and the data, the second management server 71 associates and stores them in the work machine information database 70 as shown in FIG.

As described above, by accessing the mobile terminals 40 a and 40 b and the second management server 71, data associated with the user management code and the machine management code can be stored in the work machine information database 70.
As shown in FIG. 10, since the user management code stored in the work machine information database 70 is information (for example, digitization or symbolization) obtained by coding information about the user, the user management code is directly viewed. However, it is impossible to know who the user is, the user's name, the user's address, and the user's telephone number. In addition, if the machine management code stored in the work machine information database 70 is also a code obtained by coding information related to the work machine (for example, digitization or symbolization), even if the machine management code is directly viewed, It is desirable not to be able to grasp the machine, the work machine serial number, model, data communication device serial number, and the like.

In other words, the work machine information database 70 stores data in association with a user management code that encodes information about the user and information about the mobile terminal and a machine management code that codes the information about the work machine. The confidentiality of such information can be ensured.
Now, when visually checking which user's data is stored in the work machine information database 70 and which work machine's data, the second management server 71 to the first management server 50a, The user management code and the machine management code are transmitted to 50b (step S517). When receiving the user management code and the machine management code transmitted from the second management server 71, the first management servers 50a and 50b use the management data table or the like to obtain information about the user corresponding to the user management code (for example, the user Name, address, etc.), information on mobile terminals (telephone number, etc.), information on work equipment (manufacturing machine manufacturing number, data communication device manufacturing number, etc.) are extracted (step S518), and the extracted various information is extracted. It transmits to the 2nd management server 71 (step S519).

In this way, by collecting the user management database 60 of the first management servers 50a and 50b and the work machine information database 70 of the second management server 71, the data collected on the work machine via the data communication device 30 can be collected. It can be managed in association with a user and a machine (a work machine or a device attached to the work machine). Further, by organizing the data stored in the work machine information database 70, for example, it can be used for work plans and work reports in farm work, maintenance of work machines, or the like.
[Second Embodiment]
In the second embodiment, even when the mobile terminal identification information (output mobile information) output from the mobile terminals 40a and 40b is already registered in the user management database 60, the output work machine information corresponding to the output mobile information The registration of can be added. Registration of output work machine information is added by the registration unit 52 provided in the first management servers 50a and 50b described above. In the second embodiment, differences in configuration will be described. Other configurations are the same as those in the above-described embodiment.

  For example, as shown in FIG. 12 (a), “012-3456-7890” is output to the first management servers 50a and 50b as output portable information in the state where the portable terminal identification information and the work implement identification information are stored. Assume that “20112, M115A” is output to the first management servers 50a and 50b as the output work machine information. In this case, “012-3456-7890” that is the output portable information is already stored in the user management database 60 as the stored portable information, but “20112, M115A” that is the output work machine information is stored. There will be no. That is, “012-3456-7890” is already registered in the user management database 60, but “20112, M115A” is not registered in the user management database 60.

  Only when the first permission key has already been issued for the output portable information “012-3456-7890”, the registration unit 52 is the output portable information as shown in FIG. “012-3456-7890” and output work machine information “20112, M115A” are stored in association with each other, and “012-3456-7890”, “20112, M115A”, and the first permission key are stored. Correspondingly, “20112, M115A” is additionally registered in the user management database 60.

As described above, according to the present invention, even if the data communication device 30 is additionally mounted on the work machine, if the added data communication device and the portable terminals 40a and 40b are present, the newly added data communication device is used. Data on the work equipment can be easily acquired. For example, a data communication device can be temporarily added for maintenance of the work machine, and data for performing maintenance can be acquired using the added data communication device.
[Third Embodiment]
In the third embodiment, unlike the second embodiment, when the work machine specifying information (output work machine information) output from the mobile terminals 40a and 40b is already registered in the user management database 60, this output is performed. Registration of output portable information corresponding to work implement information can be added. The registration of the output mobile information is added by the registration unit 52 provided in the first management servers 50a and 50b. In the third embodiment, different points of the configuration will be described. Other configurations are the same as those in the above-described embodiment.

  For example, as shown in FIG. 13A, “012-9472-3000” is output to the first management server 50c as the output portable information in the state where the portable terminal identification information and the work implement identification information are stored. Assume that “10006, M135A” is output to the first management server 50c as work implement information. In this case, “012-9472-3000” that is output portable information is not stored in the user management database 60 as stored portable information, while “10006, M135A” that is output work machine information is stored. It will be. That is, “10006, M135A” is already registered in the user management database 60, but “012-9472-3000” is not registered in the user management database 60.

  Only when the first permission key has already been issued for “10006, M135A”, which is the output work machine information, the registration unit 52, as shown in FIG. "012-9472-3000" and output work machine information "10006, M135A" are stored in association with each other, and "012-9472-3000", "10006, M135A" and the first permission key Then, “012-9472-3000” is additionally registered in the user management database 60.

  As described above, according to the present invention, even when a mobile terminal and a data communication device (work machine) are already associated with each other, data from the data communication device can be easily obtained using the added mobile terminal. be able to. For example, it is possible to acquire data using a portable terminal of a service person of the work machine. Moreover, even when a plurality of operators use one work machine, data can be acquired using each operator's mobile terminal.

The above-described data communication device 30 may be any device that can acquire data on the work implement. However, the data communication device 30 may use various data (tractor data) when the work implement (for example, the tractor 1) is operating. 1) is preferably collected and stored automatically.
For example, when a cultivator is connected to the rear part of the tractor 1 as the working device 9 and the tractor 1 is operated, data such as the rotational speed of the rotary, the load of the rotary, the engine rotational speed, the vehicle speed, and the tilling depth are stored in the vehicle communication network The data communication device 30 acquires data such as the rotational speed of the rotary, the load of the rotary, the engine speed, the vehicle speed, and the tilling depth via the vehicle communication network.

  In addition, when the work device 9 is a fertilizer spraying device, a pesticide spraying device, or a seeding spraying device, data such as vehicle speed, engine speed, spraying amount (fertilizer spraying amount, pesticide spraying amount, seeding spraying amount) are stored in the vehicle communication network. The data communication device 30 outputs the vehicle speed, the engine speed, the fertilizer application amount, the agricultural chemical application amount, and the seeding application amount. Alternatively, when the work device 9 is a harvesting device, data such as the vehicle speed, the engine speed, and the harvest amount are output on the vehicle communication network, and the data communication device 30 acquires the vehicle speed, the engine speed, and the harvest amount. .

The collected data is stored in the data communication device 30. The data stored in the data communication device 30 is output to the mobile terminals 40a and 40b after the pairing between the data communication device 30 and the mobile terminals 40a and 40b is established (after the data transmission permission is given). It is preferable to make it. When the data communication device 30 is attached to an agricultural machine such as a tractor, a combiner, or a rice transplanter to which the work device 9 is attached, work data obtained by performing the farm work with the agricultural machine can be acquired.
[Fourth Embodiment]
In the second modified example described above, the work machine information of the second management server 71 in which the user management code and the machine management code and the data acquired by the portable terminals 40a and 40b are arranged separately from the first management servers 50a and 50b. Although it was made to preserve | save in the database 70, in the data communication system of the working machine of 4th Embodiment, as shown in FIG. 14, the user management code | cord | chord and machine management code | cord | chord, the data which portable terminal 40a, 40b acquired, Are stored in the work machine information database 70 provided in the first management server 50a, 50b.

  Similarly to FIG. 9, the work machine information database 70 provided in the first management server 50a, 50b is also associated with information related to the user and information related to the mobile terminal, and a user management code is allocated, and also related to information related to the work machine. And a machine management code is assigned. The work machine information database 70 stores a management data table for extracting information about the user, information about the mobile terminal, and information about the work machine from the user management code and the machine management code.

FIG. 15 summarizes the operation of the data communication system of the work machine in the fourth embodiment. Note that description of operations (processes) similar to those of the above-described embodiment is omitted.
As shown in FIG. 15, when the issuance of the first permission key is completed, the first management servers 50a and 50b output the first permission key to the portable terminals 40a and 40b (step S600). Further, the first management servers 50a and 50b receive the first permission key from the mobile terminals 40a and 40b, and the MAC addresses of the mobile terminals 40a and 40b (physical addresses on the network assigned to the mobile terminals 40a and 40b). Is requested (step S601).

Furthermore, the first management server 50a, 50b also assigns the MAC address of the data communication device 30 (assigned to the data communication device 30) to the data communication device 30 to which the portable terminals 40a, 40b that receive the first permission key are connected. A physical address on the network) is requested via the portable terminals 40a and 40b (step S602).
The portable terminals 40a and 40b transmit the MAC addresses of their own portable terminals 40a and 40b to the first management servers 50a and 50b in response to requests for the MAC addresses of the first management servers 50a and 50b (step S603). The data communication device 30 transmits the MAC address of its own data communication device 30 to the first management servers 50a and 50b via the portable terminals 40a and 40b in response to requests for the MAC addresses of the first management servers 50a and 50b ( Step S604).

When the mobile terminals 40a and 40b access the first management servers 50a and 50b,
If the first management servers 50a and 50b can already acquire the MAC addresses of the portable terminals 40a and 40b and the MAC address of the data communication device 30, the processing from step S601 to step S604 may be omitted.
When acquiring the MAC addresses of the mobile terminals 40a and 40b, the first management servers 50a and 50b use the MAC addresses of the mobile terminals 40a and 40b as user management codes, and store the user management codes in the user management database 60 (step S605). ). Further, when the first management server 50a, 50b acquires the MAC address of the data communication device 30, the MAC address of the data communication device 30 is used as a machine management code, and the machine management code is stored in the user management database 60 (step S606). ).

  Further, the first management server 50a, 50b issues a second permission key for accessing the work machine information database 70 after outputting the first permission key (step S607), and the first management server 50a, 50b. (Step S608). The first management servers 50a and 50b transmit the second permission key to the portable terminals 40a and 40b (step S609). When receiving the second permission key, the portable terminals 40a and 40b store the second permission key (step S610).

  Next, when the data of the portable terminals 40a and 40b are stored in the work machine information database 70, the portable terminals 40a and 40b transmit the second permission key stored therein to the first management servers 50a and 50b. (Step S611). When receiving the second permission key transmitted from the portable terminals 40a and 40b, the first management servers 50a and 50b determine whether or not the second permission key corresponding to the portable terminals 40a and 40b is stored ( When the second permission key is stored in step S612), the first management servers 50a and 50b permit (connection permission) access to the work machine information database 70 of the portable terminals 40a and 40b (step S613).

  After permitting access to the work machine information database 70 of the portable terminals 40a and 40b (after allowing login), the portable terminals 40a and 40b request the MAC address (machine management code) from the data communication device 30 (step S614). Then, when the mobile terminals 40a and 40b acquire the MAC address (machine management code) of the data communication device 30 (step S615), the mobile terminals 40a and 40b receive their own MAC address (user management code) and data communication. The MAC address (machine management code) of the device 30 and the data are transmitted to the first management servers 50a and 50b (step S616). When the first management servers 50a and 50b acquire the user management code, the machine management code, and the data, the first management servers 50a and 50b associate and store them in the work machine information database 70 as in FIG.

  When visually checking which user's data is stored in the work machine information database 70 and which work machine's data, the first management servers 50a and 50b store the data in the user management database 60. With reference to the user management code and machine management code (step S617), using the referenced user management code and machine management code, the management data table, etc., information on the user corresponding to the user management code, information on the mobile terminal, work Information on the machine (manufacturing machine serial number, data communication equipment serial number, etc.) is extracted (step S618).

As described above, according to the present invention, since a unique MAC address is used as a user management code or a machine management code, it becomes easy for a user, a machine, or the like to manage, and the use of the MAC address simplifies a database or performs communication processing. Can be simplified.
