The management server 3 is a server for managing the work information of the workers A, B, and C, and for causing the workers A, B, and C to browse the work information. The management server 3 provides the Web page to the worker terminals 2A, 2B, and 2C. The management server 3 is composed of a personal computer (PC), and includes a control device (PC main body) 31, a display 32, and an operation device 33 such as a mouse and a key hood. The control device 31 includes a CPU 31A, a memory 31B, a hard disk 31C, and the like.

The work information management table 41, the edit / reference authority table 42, the sharing request status table 43, and the like are stored in the hard disk 31C.
FIG. 4 is a schematic diagram showing an example of the contents of the work information management table 41.
In the work information management table 41, the worker ID, the worker name, the work area ID, the work name, the work machine, the positioning information at the time of work, the polygon, and the work are displayed for each work area (for each work period) in which the work is performed. Area, work start / end time and work cost are stored. Of these information, the work name, the work machine, the positioning information at the time of work, the polygon, the work area, the work start / end time, and the work cost are the work information.

The "worker ID" is a pre-registered worker ID. Here, the worker IDs of the worker A, the worker B, and the worker C are shown as A, B, and C, respectively.
The "worker name" is the name of the worker. In the following, for convenience of explanation, the worker names of the worker A, the worker B, and the worker C will be referred to as A, B, and C, respectively.
The "work area ID" is an ID for specifying the work area, and is assigned to each work area where the work is performed. Here, the work area IDs of the work area A1, the work area A2, the work area B1, the work area C1 and the work area C2 shown in FIGS. 2A to 2C are shown as A1, A2, B1, C1 and C2, respectively. There is.

Each worker A, B, C operates the worker terminals 2A, 2B, 2C, respectively, opens the homepage provided by the management server 3, and performs a login operation to acquire a Web page dedicated to himself / herself. Is possible. Then, each worker A, B, and C can view and edit work information related to the work performed by himself / herself on his / her own Web page.
Further, in this embodiment, each worker A, B, and C can make a sharing request for sharing work information with other workers on his / her own Web page. Further, each worker A, B, and C can allow or reject a sharing request from another person on his / her own Web page.

FIG. 5A is a schematic diagram showing an example of the contents of the edit / reference authority table 42.
In the edit / reference authority table 42, the worker ID of the worker who has the edit authority and the worker ID of the worker who has the reference authority are stored for each work area ID. In the example of FIG. 5A, the work area ID includes the above-mentioned A1, A2, B1, C1 and C2.
Editing authority means the authority to view and edit work information. In this embodiment, editing authority for a work area is given only to the worker who worked on the work area. Therefore, as shown in FIG. 5A, the worker A has the editing authority for the work areas A1 and A2, the worker B has the editing authority for the work area B1, and the work areas C1 and C2 have the editing authority. Worker C has editing authority for the above.

The reference authority means the authority to view the work information, although the work information cannot be edited. As will be described later, the reference authority is related to the sharing request to the first worker and the second worker when the sharing request from one first worker is granted by another second worker. It is given to the work area of the other party.
The example of FIG. 5A shows a state in which no sharing request is made. Therefore, reference authority is not given to any of the work areas A1, A2, B1, C1, and C2.

FIG. 6A is a schematic diagram showing a format example of the sharing request status table 43.
In the sharing request status table 43, when the management server 3 receives the sharing request command from a certain worker, the ID of the sharing target area, the ID of the request request source, the ID of the request request destination, and the ID of the request request destination are displayed. The request request date and the request expiration date are stored in the management server 3. When a worker makes a sharing request, specify the work area in which the work information is to be shared among the work areas in which the worker has worked. This designated work area is the shared area.

The "request requester" is the worker who made the sharing request.
The "request request destination" is a worker to whom a sharing request is requested. More specifically, the "request request destination" is a worker who has worked on an area other than the request request source that at least partially overlaps with the "shared target area". The "request request destination" is specified by the management server 3.

The "request request date" is the date and time when the sharing request was received.
The "request expiration date" is a date indicating an expiration date during which the management server 3 can make an inquiry to the "request request destination" whether to allow or deny the sharing request. The time may be included in the "request expiration date".
Returning to FIG. 1, the CPU 31A includes a work area designation unit 51, a work area identification unit 52, an inquiry unit 53, and a sharing unit 54 as functional processing units.

The work area designation unit 51 requests the first worker who wants to request sharing of work information among a plurality of workers A, B, and C to share the work information among the work areas of the first worker. The first work area (shared target area) is specified.
The work area specifying unit 52 is a second work performed by a second worker who is at least partially overlapped with the designated first work area and is a worker different from the first worker among a plurality of workers. Identify the area.

The inquiry unit 53 inquires whether or not to allow the second worker to share the work information with the first worker.
The sharing unit 54 permits the first worker to view at least a part of the work information in the second work area when the second worker permits the sharing of the work information with the first worker. Allow the second worker to view at least a portion of the work information in the first work area.

7A and 7B are sequence diagrams for explaining the operation of the work information management system 1.
Here, the operation of the work information management system 1 when the worker A designates the work area A2 as the sharing target area and makes a sharing request will be described.
Although not shown, the worker A operates the worker terminal 2A to open the homepage provided by the management server 3 and performs a login operation. As a result, the management server 3 (work area designation unit 51 of the management server 3) transmits the Web page dedicated to the worker A to the worker terminal 2A, so that the Web page dedicated to the worker A is the display of the worker terminal 2A. It is displayed on 22.

The worker A designates the work area A2 as the sharing target area on this dedicated Web page and makes a sharing request. As a result, as shown in FIG. 7A, a sharing request command including the work area ID of the work area A2 is transmitted from the worker terminal 2A to the management server 3 (step S1).
Upon receiving this sharing request command, the management server 3 (work area specifying unit 52 of the management server 3) performs data writing processing to the sharing request status table 43 (step S2).

Specifically, the management server 3 first identifies as a reference area an area that overlaps at least a part of the shared target area among the workers other than the request request source, and also selects the worker who worked on the reference area. Identify. In this example, since the request request source is the worker A and the sharing target area is A2, the management server 3 uses the work areas B1, C1 and C2 as reference areas that at least partially overlap with the area A2. Identify. Further, the management server 3 identifies the worker B as the worker who worked on the reference area B1, and identifies the worker C as the worker who worked on the reference areas C1 and C2.

Then, as shown in FIG. 6B, the management server 3 requests the sharing request status table 43 with the ID of the sharing target area (A2 in this example), the ID of the request request source (A in this example), and the request. The ID of the request destination (B, C in this example), the request request date, and the request expiration date are stored.
After that, if the worker B operates the worker terminal 2B to open the homepage provided by the management server 3 and then performs a login operation (step S3), the management server 3 is shared. It is determined whether or not the worker B is registered as the request request destination in the request status table 43 (step S4).

In this example, as shown in FIG. 6B, the worker B is registered as the request request destination in the sharing request status table 43. Therefore, since the affirmative determination is made in step S4 (step S4: YES), the management server 3 (inquiry unit 53 of the management server 3) shares the work information with the worker A who requested the request to the worker B. An inquiry Web page for inquiring whether to allow or not is created and transmitted (step S5).

Although not shown, if worker B is not registered as a request request destination in the sharing request status table 43 (step S4: NO), the management server 3 displays a normal Web page dedicated to worker B. Create and send to the worker terminal 2B.
Upon receiving the inquiry Web page, the worker terminal 2B displays the inquiry screen (step S6). FIG. 8 shows an example of the inquiry screen 101 displayed on the worker terminal 2B. On the inquiry screen 101, the work area A2, which is a shared target area, and the work area B1 worked by the worker B are displayed in an overlapping state. Further, on the inquiry screen 101, a message indicating that the sharing request has been made by the worker A who is the request request source, and an OK button 102 and a NO button 103 for selecting whether to allow or reject the sharing request are displayed. , Send button 104 and so on are displayed. The OK button 102 is selected when the sharing request is permitted, and the NO button 103 is selected when the sharing request is rejected.

The worker B selects one of the OK button 102 and the NO button 103, and then presses the send button 104. When the send button 104 is pressed (step S7), the permission / denial selection result is transmitted to the management server 3 (step S8).
When the management server 3 receives the permission / denial selection result from the worker terminal 2B, the management server 3 performs table update processing according to the selection result (step S9).

Here, it is assumed that the selection result is permission. In this case, as shown in FIG. 5B, the management server 3 (shared unit 54 of the management server 3) sets the reference authority item corresponding to the work area A2 in the edit / reference authority table 42 to the worker B. ID is written, and the ID of worker A is written in the item of reference authority corresponding to the work area B1. Further, the management server 3 deletes B from the ID of the request request destination for the work area A2 in the sharing request status table 43 of FIG. 6B. As a result, the contents of the sharing request state table 43 change as shown in FIG. 6C.

As a result, the worker A is given the right to browse the work information in the work area B1, and at the same time, the worker B is given the right to browse the work information in the work area A2.
The management server 3 transmits to the worker terminal a Web page dedicated to the worker B that reflects the contents of the updated edit / reference authority table 42 (reference authority after the update) (step S10). As a result, the worker B can browse the work information of the work area A2 on the Web page dedicated to the worker B.

Further, when the management server 3 sends the Web page dedicated to the worker A to the worker A, the management server 3 reflects the contents of the updated edit / reference authority table 42 (reference authority after the update). A dedicated Web page is sent to the worker terminal. As a result, the worker A can browse the work information in the work area B1 on the Web page dedicated to the worker A.
If the selection result is rejected, the management server 3 does not update the contents of the edit / reference authority table 42, and instead of updating the contents of the edit / reference authority table 42, the request request destination for the work area A2 of the shared request status table 43 in FIG. 6B. Delete B from the ID.

Further, as shown in FIG. 7B, when the worker C subsequently operates the worker terminal 2C to open the homepage provided by the management server 3 and then performs a login operation (step S11). ), The management server 3 determines whether or not the worker C is registered as the request request destination in the sharing request status table 43 (step S12).
In this example, as shown in FIG. 6C, the worker C is registered as the request request destination in the sharing request status table 43. Therefore, since the affirmative determination is made in step S12 (step S12: YES), the management server 3 (inquiry unit 53 of the management server 3) shares the work information with the worker A who requested the request to the worker C. An inquiry Web page for inquiring whether to allow or not is created and transmitted (step S13).

Although not shown, if worker C is not registered as a request request destination in the sharing request status table 43 (step S12: NO), the management server 3 displays a normal Web page dedicated to worker C. Create and send to the worker terminal 2C.
Upon receiving the inquiry Web page, the worker terminal 2C displays the inquiry screen (step S14). FIG. 9 shows an example of the inquiry screen 111 displayed on the worker terminal 2C.

On the inquiry screen 111, the work area A2, which is a shared target area, and the work areas C1 and C2 worked by the worker C are displayed in an overlapping state. Further, on the inquiry screen 111, a message indicating that the sharing request has been made by the worker A who is the request requesting source for the work area C1 and an OK for selecting whether to allow or reject the sharing request are displayed. Button 112 and NO button 113 are displayed. Further, on the inquiry screen 111, a message indicating that the worker A who is the request request source has made a sharing request to the work area C2, and an OK for selecting whether to allow or reject the sharing request. Button 115 and NO button 116 are displayed. Further, the transmission button 117 is displayed on the inquiry screen 111.

The worker C selects one of the OK button 112 and the NO button 113 for the work area C1. Further, the worker C selects one of the OK button 115 and the NO button 116 for the work area C2. After this, the worker C presses the send button 117. When the send button 117 is pressed (step S15), the permission / denial selection result for the work area C1 and the permission / denial selection result for the work area C2 are transmitted to the management server 3 (step S16).

When the management server 3 receives the permission / denial selection result from the worker terminal 2C, the management server 3 performs table update processing according to the selection result (step S17).
Here, it is assumed that the selection result for the work area C1 is rejected and the selection result for the work area C2 is permission. In this case, as shown in FIG. 5C, the management server 3 (shared unit 54 of the management server 3) sets the reference authority item corresponding to the work area A2 in the edit / reference authority table 42 to the worker C. ID is written, and the ID of worker A is written in the item of reference authority corresponding to the work area C2. Further, the management server 3 deletes C from the ID of the request request destination for the work area A2 of the sharing request status table 43 of FIG. 6C. As a result, the contents of the sharing request status table 43 change as shown in FIG. 6D.

As a result, the worker A is given the right to browse the work information in the work area C2, and at the same time, the worker C is given the right to browse the work information in the work area A2.
The management server 3 transmits to the worker terminal a Web page dedicated to worker C that reflects the contents of the updated edit / reference authority table 42 (reference authority after update) (step S18). As a result, the worker C can browse the work information in the work area A2 on the Web page dedicated to the worker C.

Further, when the management server 3 sends the Web page dedicated to the worker A to the worker A, the management server 3 reflects the contents of the updated edit / reference authority table 42 (reference authority after the update). A dedicated Web page is sent to the worker terminal. As a result, the worker A can browse the work information of the work areas B1 and C2 on the Web page dedicated to the worker A.
If both the selection result for the work area C1 and the selection result for the work area C2 are permitted, the management server 3 sets the reference authority item corresponding to the work area A2 in the edit / reference authority table 42. The ID of the worker C is written, and the ID of the worker A is written in the item of the reference authority corresponding to the work areas C1 and C2. Further, the management server 3 deletes C from the ID of the request request destination for the work area A2 of the sharing request status table 43 of FIG. 6C.

If both the selection result for the work area C1 and the selection result for the work area C2 are rejected, the management server 3 does not update the contents of the edit / reference authority table 42, and requests sharing of FIG. 6C. C is deleted from the ID of the request request destination for the work area A2 of the status table 43.
The data in the sharing request status table 43 created in step S2 is deleted when the expiration date has expired, regardless of whether or not there is a subsequent update.

According to the above-described embodiment, when different workers perform work in different areas in at least a partially overlapping area, sharing of work information among different workers is subject to the consent of the workers. It will be possible. As a result, the worker can know what kind of work the other worker has performed in the area where at least a part of the work area is overlapped with the work area in which the worker has performed the work.

Although the embodiment of the present invention has been described above, the present invention can also be implemented in other embodiments. For example, in the above-described embodiment, the work information includes a work name, a work machine, a positioning information at the time of work, a polygon, a work area, a work start / end time, and a work cost. Not limited.
Further, in the above-described embodiment, a worker who has been given reference authority to a certain work area can view all the work information in the work area. However, a worker who has been given reference authority to a certain work area may be allowed to view only a part of the work information in the work area. That is, the work information that can be viewed by the reference authority may be restricted.

Such restrictions on viewable work information may be set on the management server 3 side. Further, such a restriction on the work information that can be viewed may be set by the worker when the worker requests sharing of the work information. In this case, the worker of the sharing request source can set the restriction content for each sharing request.
Further, in the above-described embodiment, each worker terminal 2A, 2B, 2C is composed of a personal computer (PC), but each worker terminal 2A, 2B, 2C may be composed of a smartphone. ..
