  In this example, the other server 200 is owned by a software developer who develops software for processing various types of information. The other server 200 is desired by users of a plurality of terminals 210 to 210 connected via the Internet 400 (for example, users and owners of the work machines 500 to 500) based on the received information RI and the display information DI. An information processing service that processes data to be processed is provided. That is, the other server 200 configures a client side (for example, an HTML (Hyper-Text Mark-up Language) client side) with respect to the web server 140.

  The other servers 200 are used by the users of the terminals 210 to 210 when the processed data is taken into the terminals 210 to 210 (client computers). That is, the other server 200 forms a server side (for example, JAVA (registered trademark) server side) with respect to the terminals 210 to 210. Terminals 210 to 210 are connected to another server 200 by a predetermined authentication means (for example, a login ID and password input operation).

[Specific web server configuration]
The web server 140 includes a web application programming interface (WebAPI) (hereinafter simply referred to as “Web API”) and a data access object (DAO) (hereinafter simply referred to as “DAO”). ing.

  Here, the web API is a method for calling and using the function provided by the developer of the application program of the other server 200 in the web server 140 from the application program of the other server 200 via the Internet 400. That is, the web API can be used via the Internet 400 to process the data desired by the user of the terminals 210 to 210 based on the received information RI and the display information DI from the web server 140. Is. By using this web API, there is an advantage that a developer of an application program of another server 200 can develop high-functional content of the web server 140 in a shorter period of time and at a lower cost. The DAO is an object for the web server 140 to access data in the database server 110 using the web API.

  The web server 140 has a function of returning a necessary result from another server 200 via the Internet 400 using HTTP (Hypertext Transfer Protocol) communication. HTTP is a protocol used for transmitting and receiving data between the web server 140 and another server 200, and in this example, is HTTP (Hypertext Transfer Protocol Secure). HTTPS represents a state where HTTP is encrypted. By using this HTTPS, communication between the web server 140 and another server 200 can be encrypted, and wiretapping on the communication path and spoofing by a third party can be prevented. In this example, the login ID and password for identifying the user of the terminals 210 to 210 are encrypted using a common key method (specifically, an encryption algorithm AES: Advanced Encryption Standard).

(System requirements)
Operates in the web server 140

  -Data according to the request condition from the other server 200 is transmitted as text data in the markup language format.

  Here, the markup language is for describing the meaning and structure of a document or data. In this example, the markup language is XML (Extensible Markup Language). XML is an evolution of HTML. By using this XML, a user can create a markup language having a unique meaning and structure while using a unified notation.

As described above, according to the present embodiment, the remote server 100 can read the received information RI received from the work machines 500 to 500 and the display information DI processed based on the received information RI by other servers 200. The data disclosure configuration for cooperating with the information processing service provided by the other server 200 can be presented because the configuration is disclosed to the Internet 400 in a simple format. It can be used for.

(About work area judgment)
By the way, in the remote server 100 (specifically, the database server 110), when the work machine 500 performs work on a plurality of work areas (specifically, farm fields), each work area (specifically, from the work machine 500). In particular, operation information may be acquired separately for each field. The operation information can be used as display information DI processed based on the reception information RI.

  FIG. 2 is a conceptual diagram illustrating an example in which the remote server 100 obtains operation information by distinguishing each field H to H from the work machine 500 when the work machine 500 performs work on a plurality of fields H to H. It is. In addition, in FIG. 2, although the six farm fields H are illustrated, it cannot be overemphasized that the farm fields H of 2-5, 7 or more may be sufficient. Moreover, the symbol in the corner | angular part of the agricultural field H has shown the value of the latitude and the longitude of the vertex which comprises the polygonal shape (this example rectangular shape) which shows the outline of the agricultural field H.

  As shown in FIG. 2, when the work machine 500 performs work on a plurality (six in this example) of the farm fields H to H, operation information is obtained from the work machine 500 for each farm field H to H. In doing so, the remote server 100 needs to recognize which field H of the plurality of fields H to H the work machine 500 is working on.

  From this point of view, the remote server 100 uses the work area selection information (specifically, the field selection) for the operator to select the work area (specifically, the field H on which the work machine 500 is working) in the received information RI from the work machine 500. No. SNO) is included, it is possible to make the remote server 100 recognize which field H among the plurality of fields H to H the work machine 500 is working on. Here, a unique field number HNO (in this example, “203” to “208”) is assigned in advance to each of the fields H to H as work area identification information.

  Specifically, the work machine 500 includes a storage unit 510 and a display unit 520. The work machine 500 includes a plurality of pieces of work area selection information (specifically, field selection numbers SNO to SNO, in this example, “203” to “208”) respectively corresponding to the field numbers HNO to HNO of the plurality of fields H to H. Is stored in the storage unit 510 in advance. The work machine 500 displays the work area selection information (specifically, the field selection numbers SNO “203” to “208”) in the storage unit 510 on the display unit 520 so that the operator can select and input the work area selection information. . As a result, the operator can select any one of the work area selection information (work information) among the work area selection information (specifically, the field selection numbers SNO “203” to “208”) displayed on the display unit 520 of the work machine 500. The field selection number SNO) corresponding to the field H on which the machine 500 is working can be selected.

  However, if the operator correctly selects the work area selection information (specifically, the field selection numbers SNO “203” to “208”) corresponding to the field H on which the work machine 500 is working, there is no problem. If the operator does not select the work area selection information, forgets to select the work area, or selects the work area selection information in error, the work machine 500 can select any of the fields H to H. The remote server 100 cannot recognize at all whether the work is being performed, or cannot be recognized accurately.

  Therefore, even if the operator does not select the work area selection information, forgets to select it, or makes a mistake in selecting the work area selection information, the work machine 500 can select any of the plurality of farm fields H to H. It is desired that the remote server 100 can recognize whether the work is being performed on the farm field H.

  In this regard, the remote server 100 processes as follows based on the reception information RI.

  That is, the remote server 100 does not select the work area selection information (specifically, the field selection numbers SNO “203” to “208”) by the operator, or the work area selection information (specifically, selected by the operator). If the field selection number SNO “203” to “208”) is not accurate, the position information PI (latitude, longitude) sent from the work machine 500 is used. . Here, the working machine 500 acquires information including position information PI (latitude and longitude) using a global positioning system (for example, GPS: Global Positioning System).

  FIG. 3 is a schematic diagram illustrating a working state of the work machine 500. FIG. 3A shows a work state 1 in which the field identification information HID obtained based on the field selection number SNO and the temporary field identification information THID obtained based on the position information PI of the work machine 500 match. Show. FIG. 3B shows that the field identification information HID obtained based on the field selection number SNO and the temporary field identification information THID obtained based on the position information PI of the work machine 500 do not match, and The work state 2 in which the field polygon information HPI obtained based on the field identification information HID and the buffer area information BPI obtained based on the position information PI of the work machine 500 overlap is shown. FIG. 3C shows that the field identification information HID obtained based on the field selection number SNO does not match the temporary field identification information THID obtained based on the position information PI of the work machine 500, and The work state 3 in which the field polygon information HPI obtained based on the field identification information HID and the buffer area information BPI obtained based on the position information PI of the work machine 500 do not overlap is shown.

  FIG. 4 shows the field selection number SNO, the field identification information HID, the temporary field identification information THID, and the presence / absence of matching between the field identification information HID and the temporary field identification information THID for the working state of the work machine 500 shown in FIG. It is a table | surface which shows the presence or absence of the overlap of field polygon information HPI and buffer area information BPI, and the set field number HNO. In FIG. 4, “◯” indicates that the farm field identification information HID and the temporary farm field identification information THID match, or that the farm field polygon information HPI and the buffer area information BPI overlap. “X” indicates that the farm field identification information HID and the temporary farm field identification information THID do not match, or the farm field polygon information HPI and the buffer area information BPI do not overlap.

  In the present embodiment, the remote server 100 uses the work area selection information (specifically, the field selection number SNO “203”) to specify the first work area identification information (specifically, the field identification information HID “88”). And the second work area specifying information (specifically, temporary farm field identification information THID “88” or “89”) is obtained based on the position information PI (latitude, longitude) of the work machine 500, and the first work It is determined whether or not the area specifying information (specifically, the field identification information HID “88”) matches the second work area specifying information (specifically, the temporary agricultural field identification information THID “88” or “89”). If they match (see the temporary field identification information THID “88” in FIG. 3A), the operator selects the work area selection information (specifically, the field selection number SNO “203”) as correct. Two types of work areas A work area (specifically, a work area in which the work machine 500 works in an area identified by the specific information (specifically, the farm field H corresponding to the farm field identification information HID “88” or the temporary farm field identification information THID “88”)). Is set as the farm field H) of farm field number HNO “203” (see work state 1 in FIG. 4).

  On the other hand, the remote server 100 is a case where the first work area specifying information (specifically, the field identification information HID) and the second work area specifying information (specifically, the temporary field identification information THID) do not match. As a case where the first work area specifying information (specifically, the field identification information HID) and the second work area specifying information (specifically, the temporary field identification information THID) do not match, a global positioning system (for example, GPS) The position information PI (latitude and longitude) sent from the work machine 500 due to the performance limit is not good because the position accuracy is not good. In fact, it does not match and the operator does not select work area selection information. It can be considered that the selection is forgotten or the selection does not actually match due to a selection error.

  Therefore, in the present embodiment, the remote server 100 includes the first work area specifying information (specifically, the farm field identification information HID “88”) and the second work area specifying information (specifically, the temporary farm field identification information THID “ 88 ”or“ 89 ”) (see the temporary field identification information THID“ 89 ”in FIGS. 3B and 3C), the first work area specifying information (specifically, the field identification) Based on the information HID “88”), the first specific range information (specifically, see the field polygon information HPI in FIGS. 3B and 3C) is acquired, and the position information PI (latitude of the work machine 500) , Longitude) based on the second specific range information (specifically, the buffer area information BPI in FIGS. 3B and 3C) is acquired.

  Here, the field polygon information HPI is the latitude and longitude values (see FIG. 2) of the vertices constituting a polygonal shape (in this example, a quadrilateral shape) indicating the contour of the field H. The buffer area information BPI is predetermined area information centered on the position information PI (latitude, longitude) of the work machine 500. In this example, the buffer area information BPI is a predetermined radius r (for example, 10 m) centered on the position information PI (latitude, longitude) of the work machine 500 (see FIGS. 3B and 3C). ) Circle information.

  The remote server 100 determines whether or not the first specific range information (specifically, the field polygon information HPI) and the second specific range information (specifically, the buffer area information BPI) overlap. When the first specific range information (specifically, the field polygon information HPI) and the second specific range information (specifically, the buffer area information BPI) overlap (see FIG. 3B), the remote server 100 The 1 work area specifying information (specifically, the farm field identification information HID) and the second work area specifying information (specifically, the temporary farm field identification information THID) are the positional accuracy of the position information PI sent from the work machine 500. The region (specifically, the field identification) is identified by the first work area identification information (specifically, the field identification information HID “88”). The farm field H) corresponding to the information HID “88” is set as a work area where the work machine 500 works (specifically, the farm field H of the farm field number HNO “203”) (see work state 2 in FIG. 4). On the other hand, the remote server 100 has a case where the first specific range information (specifically, the field polygon information HPI) and the second specific range information (specifically, the buffer area information BPI) do not overlap (see FIG. 3C). ), The first work area specifying information (specifically, the field identification information HID) and the second work area specifying information (specifically, the temporary field identification information THID) are the non-selection or selection of the work area selection information by the operator. Forgetting to do so, it is assumed that they do not actually match due to a mistake in selection, and the area (specifically temporary area) specified by the second work area specifying information (specifically temporary field identification information THID “89”) The farm field H corresponding to the farm field identification information THID “89” is set as a work area where the work machine 500 works (specifically, the farm field H of the farm field number HNO “204”) (see work state 3 in FIG. 4).

  Thus, for example, when the work area is moved (specifically, the field number HNO) based on the work area selection information (specifically, the field H of the field selection number SNO “203”) selected by the operator. For example, the operator forgets to change the work area selection information (specifically, the field selection number SNO “204”) from the field H of “203” to the field H of the field number HNO “204”. Even if the selection of the work area selection information (specifically, the field selection number SNO “204”) is wrong, the correction based on the position information PI (latitude, longitude) of the work machine 500 is possible.

  Specifically, the database server 110 in the remote server 100 has the following control configuration.

  That is, the database server 110 (see FIG. 1) includes a control device 111 (see FIG. 1) composed of a microcomputer such as a CPU (Central Processing Unit), a mass storage device (specifically a hard disk device), a ROM (Read). A storage device 112 (see FIG. 1) including a non-volatile memory such as Only Memory) and a volatile memory such as RAM (Random Access Memory). The database server 110 controls the operation of various components by causing the control device 111 to load and execute a control program stored in advance in the ROM of the storage device 112 on the RAM of the storage device 112. .

  The control device 111 acquires the temporary farm field identification information THID based on the position information PI (latitude, longitude) of the work machine 500.

  FIG. 5 is a schematic diagram showing an example of the data structure of the first database DB1 stored by associating the temporary field identification information THID with the field polygon information HPI. In FIG. 5, the latitude and longitude are indicated by symbols instead of actual values.

  As shown in FIG. 5, the first database DB1 is stored in the storage device 112 (see FIG. 1). In the first database DB1, temporary field identification information THID is stored in advance in association with the field polygon information HPI using the field polygon information HPI (latitude, longitude) as a search key. Thereby, the control apparatus 111 can acquire temporary field identification information THID using the field polygon information HPI corresponding to the position information PI (latitude, longitude) of the work machine 500.

  The control device 111 acquires the field identification information HID based on the field selection number SNO.

  As shown in FIG. 6, the second database DB2 is stored in the storage device 112 (see FIG. 1). In the second database DB2, the field identification information HID is stored in advance in association with the field selection number SNO using the field selection number SNO as a search key. Thereby, the control apparatus 111 can acquire the field identification information HID using the field selection number SNO.

  The control device 111 acquires the field polygon information HPI based on the field identification information HID.

  FIG. 7 is a schematic diagram showing an example of the data structure of the third database DB3 stored in association with the field polygon information HPI with the field identification information HID. In FIG. 7, the latitude and longitude are indicated by symbols instead of actual values.

  As shown in FIG. 7, the third database DB3 is stored in the storage device 112 (see FIG. 1). In the third database DB3, field polygon information HPI (latitude and longitude) is stored in advance in association with the field identification information HID using the field identification information HID as a search key. Thereby, the control apparatus 111 can acquire the field polygon information HPI using the field identification information HID.

  FIG. 8 and FIG. 9 are flowcharts respectively showing a first half part and a second half part of an example of a determination control operation of a work area in which work is performed by the work machine 500.

  In the control operation of the inconvenience handling system according to the present embodiment, as shown in FIG. 8, first, control device 111 acquires temporary farm field identification information THID based on position information PI (latitude, longitude) of work implement 500. (Step S1). Specifically, the control device 111 temporarily uses the first database DB1 (see FIG. 5) in the storage device 112 (see FIG. 1) from the field polygon information HPI corresponding to the position information PI (latitude, longitude) of the work machine 500. The field identification information THID (for example, “88” or “89”) is acquired.

  Next, the control device 111 determines whether or not the temporary farm field identification information THID can be acquired (step S2). When the temporary farm field identification information THID is acquired (step S2: No), the step shown in FIG. On the other hand, if the temporary farm field identification information THID has not been acquired (step S2: Yes), the process proceeds to step S3.

  Next, the control device 111 determines whether or not the field selection number SNO cannot be acquired (step S3), and when the field selection number SNO is not acquired (step S3: Yes), the temporary field identification information THID. Is set to a null value (empty value) (step S7), and when the field selection number SNO is acquired (step S3: No), the field identification information HID is acquired based on the field selection number SNO ( Step S4). Specifically, the control device 111 acquires the field identification information HID from the field selection number SNO using the second database DB2 (see FIG. 6) in the storage device 112 (see FIG. 1).

  Next, the control device 111 determines whether or not the field identification information HID cannot be acquired (step S5). When the field identification information HID is acquired (step S5: No), the field is added to the temporary field identification information THID. The identification information HID is set (step S6), and when the field identification information HID is not acquired (step S5: Yes), a null (NULL) value is set to the temporary field identification information THID (step S5). S7).

  Next, as shown in FIG. 9, the control device 111 determines whether or not the field selection number SNO has been acquired (step S8). Specifically, the control device 111 selects one of the field selection numbers SNO (for example, “203”) from among the field selection numbers SNO displayed on the display unit 520 of the work machine 500, and sets the field selection number SNO. It is determined whether or not it has been acquired.

  When the control device 111 has not acquired the field selection number SNO (step S8: No), the control device 111 identifies the area (for example, the temporary field identification information THID “88”) specified by the temporary field identification information THID (for example, “88”). Is set as the field H (for example, field H of field number HNO “203”) on which the work machine 500 works (step S16), and the processing operation is terminated.

  On the other hand, when acquiring the field selection number SNO (step S8: Yes), the control device 111 acquires the field identification information HID based on the field selection number SNO (step S9). Specifically, the control device 111 uses the second database DB2 (see FIG. 6) in the storage device 112 (see FIG. 1) from the field selection number SNO (eg, “203”) to identify the field identification information HID (eg, “88”). To get.

  Next, the control device 111 determines whether or not the field identification information HID (for example, “88”) matches the temporary field identification information THID (for example, “88” or “89”) (Step S10). When the identification information HID and the temporary field identification information THID match (see work state 1 in FIG. 3A) (step S10: Yes), the field selection number SNO selected by the operator is regarded as correct, and the field The work machine 500 uses the area identified by the identification information HID or the temporary farm field identification information THID (the field H corresponding to the farm field identification information HID “88” or the temporary farm field identification information THID “88” in the example of FIG. 3A). The field H to be operated (field H of field number HNO “203” in the example of FIG. 3A) is set (step S11), and the processing operation is terminated.

  On the other hand, when the field identification information HID and the temporary field identification information THID do not match (step S10: No), the control device 111 acquires the field polygon information HPI based on the field identification information HID (step S12). Specifically, the control device 111 uses the third database DB3 (see FIG. 7) in the storage device 112 (see FIG. 7) from the farm field identification information HID (eg, “88”) to display the field polygon information HPI (eg, “A1, B1”). , “A2, B2”, “A3, B3”, “A4, B4”).

  Next, the control device 111 acquires the buffer area information BPI based on the position information PI (latitude, longitude) of the work machine 500 (step S13). Specifically, the control device 111 acquires predetermined area information centered on the position information PI (latitude, longitude) of the work machine 500 as the buffer area information BPI. In this example, the buffer area information BPI is a circle having a predetermined radius r (for example, 10 m) (see FIGS. 3B and 3C) centered on the position information PI (latitude, longitude) of the work machine 500. Information. Here, the setting of the predetermined area information can be changed for each work machine 500.

  Next, the control device 111 determines whether or not the field polygon information HPI and the buffer area information BPI overlap (step S14).

  When the field polygon information HPI (see the bold line in FIG. 3B) and the buffer area information BPI (see the circle in FIG. 3B) overlap, the control device 111 (see work state 2 in FIG. 3B). (Step S14: Yes), the field identification information HID and the temporary field identification information THID are not matched because the position accuracy of the position information PI sent from the work machine 500 is not good. The region identified by the field identification information HID (“88” in the example of FIG. 3B) (the field H corresponding to the field identification information HID “88” in the example of FIG. 3B). It is set as the field H (the field H of the field number HNO “203” in the example of FIG. 3B) on which the work machine 500 works (step S15), and the processing operation is terminated.

  On the other hand, the control device 111 does not overlap the field polygon information HPI (see the bold line in FIG. 3C) and the buffer area information BPI (see the circle in FIG. 3C) (working state in FIG. 3C). 3) (step S14: No), the field identification information HID and the temporary field identification information THID actually match because the operator has not selected or forgotten to select the field selection number SNO, and the selection is wrong. The field H corresponding to the area (in the example of FIG. 3 (c), the temporary farm field identification information THID “89”) identified by the temporary farm field identification information THID (“89” in the example of FIG. 3 (c)). ) Is set as the field H (the field H of the field number HNO “204” in the example of FIG. 3C) on which the work machine 500 works (step S16), and the processing operation ends. When processing step S16, a message indicating that the field selection number SNO selected by the operator has changed the field selection number SNO corresponding to the temporary field identification information THID is displayed on the display unit 520 to notify the operator. It may be.

  In this example, the fields H and H of the field numbers HNO “203” and “204” are illustrated, but it is needless to say that other fields H may be used.
