More specifically, the “request request destination” is, among the workers other than the request request source, a worker who has worked on an area at least partially overlapping with the “sharing target area”. The “request request destination” is specified by the management server 3.
　「要求依頼日」は、共有化要求を受信した日時である。 “Request date” is the date and time when the sharing request was received.
　「要求有効期限」は、管理サーバ３が「要求依頼先」に対して、当該共有化要求を許可するか拒否するかの問合せを行うことが可能な期限を示す年月日である。「要求有効期限」に、時刻を含めてもよい。 The “request expiration date” is the date and time when the management server 3 can inquire of the “request request destination” whether to permit or reject the sharing request. The “request expiration date” may include the time.
　図１に戻り、ＣＰＵ３１Ａは、機能処理部として、作業領域指定部５１と、作業領域特定部５２と、問合せ部５３と、共有化部５４とを含む。 Returning to FIG. 1, the CPU 31A includes a work area designating unit 51, a work area specifying unit 52, an inquiry unit 53, and a sharing unit 54 as functional processing units.
　作業領域指定部５１は、複数の作業者Ａ，Ｂ，Ｃのうち作業情報の共有化を要求したい第１作業者に、第１作業者の作業領域のうち作業情報の共有化を要求する領域である第１作業領域（共有化対象領域）を指定させる。 The work area designation unit 51 is an area of the work areas of the first worker that requests sharing of work information from a first worker who wants to share work information among the plurality of workers A, B, and C. The first work area (shared area) is designated.
　作業領域特定部５２は、指定された第１作業領域と少なくとも一部が重なりかつ複数の作業者のうち第１作業者とは異なる作業者である第２作業者が作業を行った第２作業領域を特定する。 The work area specifying unit 52 is a second work in which a second worker who is a worker different from the first worker among the plurality of workers at least partially overlaps the designated first work area Identify the area.
　問合せ部５３は、第２作業者に第１作業者との作業情報の共有化を許可するか否かを問い合わせる。 The inquiry unit 53 inquires whether the second worker is allowed to share the work information with the first worker.
　共有化部５４は、第２作業者が第１作業者との作業情報の共有化を許可した場合に、第１作業者に第２作業領域の作業情報の少なくとも一部の閲覧を許可しかつ第２作業者に第１作業領域の作業情報の少なくとも一部の閲覧を許可する。 The sharing unit 54 allows the first worker to view at least a part of the work information in the second work area when the second worker permits sharing of the work information with the first worker, and The second worker is permitted to view at least a part of the work information in the first work area.
　図７Ａおよび図７Ｂは、作業情報管理システム１の動作を説明するためのシーケンス図である。 7A and 7B are sequence diagrams for explaining the operation of the work information management system 1.
　ここでは、作業者Ａが作業領域Ａ２を共有化対象領域として指定して共有化要求を行った場合の作業情報管理システム１の動作について説明する。 Here, the operation of the work information management system 1 when the worker A designates the work area A2 as a sharing target area and makes a sharing request will be described.
　図示はしていないが、作業者Ａは、作業者端末２Ａを操作して、管理サーバ３が提供するホームページを開き、ログイン操作を行う。これにより、管理サーバ３（管理サーバ３の作業領域指定部５１）は、作業者Ａ専用のＷｅｂページを作業者端末２Ａに送信するので、作業者Ａ専用のＷｅｂページが作業者端末２Ａのディスプレイ２２に表示される。 Although not shown, the worker A operates the worker terminal 2A to open the home page provided by the management server 3 and perform 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 displayed on the display of the worker terminal 2A. 22 is displayed.
　作業者Ａは、この専用Ｗｅｂページ上で、作業領域Ａ２を共有化対象領域として指定して共有化要求を行う。これにより、図７Ａに示すように、作業者端末２Ａから管理サーバ３に、作業領域Ａ２の作業領域ＩＤを含む共有化要求コマンドが送信される（ステップＳ１）。 The worker A makes a sharing request by designating the work area A2 as a sharing target area on this dedicated Web page. As a result, as shown in FIG. 7A, the 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).
　管理サーバ３（管理サーバ３の作業領域特定部５２）は、この共有化要求コマンドを受信すると、共有化要求状態テーブル４３へのデータ書込処理を行う（ステップＳ２）。 When the management server 3 (work area specifying unit 52 of the management server 3) receives this sharing request command, it performs a data writing process to the sharing request status table 43 (step S2).
　具体的には、管理サーバ３は、まず、要求依頼元以外の作業者のうち、共有化対象領域と少なくとも一部が重複する領域を参照領域として特定するとともに、参照領域を作業した作業者を特定する。この例では、要求依頼元は作業者Ａであり、共有化対象領域はＡ２であるので、管理サーバ３は、参照領域として、領域Ａ２と少なくとも一部が重複する作業領域Ｂ１、Ｃ１およびＣ２を特定する。また、管理サーバ３は、参照領域Ｂ１を作業した作業者として作業者Ｂを特定し、参照領域Ｃ１およびＣ２を作業した作業者として作業者Ｃを特定する。 Specifically, the management server 3 first identifies, from among workers other than the request request source, a region that at least partially overlaps the sharing target region as a reference region, and identifies the worker who worked on the reference region. Identify. In this example, since the request requester is the worker A and the sharing target area is A2, the management server 3 uses the work areas B1, C1, and C2 that at least partially overlap with the area A2 as the reference area. Identify. Further, the management server 3 specifies the worker B as a worker who has worked on the reference area B1, and specifies the worker C as a worker who has worked on the reference areas C1 and C2.
　そして、管理サーバ３は、図６Ｂに示すように、共有化要求状態テーブル４３に、共有化対象領域のＩＤ（この例ではＡ２）と、要求依頼元のＩＤ（この例ではＡ）と、要求依頼先のＩＤ（この例ではＢ，Ｃ）と、要求依頼日と、要求有効期限とを記憶する。 Then, as illustrated in FIG. 6B, the management server 3 sets an ID of the sharing target area (A2 in this example), a request requester ID (A in this example), and a request in the sharing request state table 43. The ID of the request destination (B, C in this example), the request request date, and the request expiration date are stored.
　この後において、作業者Ｂが、作業者端末２Ｂを操作して、管理サーバ３が提供するホームページを開いた後、ログイン操作を行った場合には（ステップＳ３）、管理サーバ３は、共有化要求状態テーブル４３に作業者Ｂが要求依頼先として登録されているか否かを判定する（ステップＳ４）。 After that, when the worker B operates the worker terminal 2B to open the home page provided by the management server 3 and then performs a login operation (step S3), the management server 3 is shared. It is determined whether the worker B is registered as a request request destination in the request status table 43 (step S4).
　この例では、図６Ｂに示すように、共有化要求状態テーブル４３に作業者Ｂが要求依頼先として登録されている。したがって、ステップＳ４において肯定判定されるので（ステップＳ４：ＹＥＳ）、管理サーバ３（管理サーバ３の問合せ部５３）は、作業者Ｂに要求依頼元の作業者Ａとの作業情報の共有化を許可するか否を問い合わせるための問合せＷｅｂページを作成して送信する（ステップＳ５）。 In this example, as shown in FIG. 6B, the worker B is registered as a request request destination in the sharing request status table 43. Therefore, since an affirmative determination is made in step S4 (step S4: YES), the management server 3 (the 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 permit is created and transmitted (step S5).
　なお、図示しないが、共有化要求状態テーブル４３に作業者Ｂが要求依頼先として登録されていない場合には（ステップＳ４：ＮＯ）、管理サーバ３は、通常の作業者Ｂ専用のＷｅｂページを作成して作業者端末２Ｂに送信する。 Although not shown, when the 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 the worker B. It is created and transmitted to the worker terminal 2B.
　作業者端末２Ｂは、問合せＷｅｂページを受信すると、問合せ画面を表示する（ステップＳ６）。作業者端末２Ｂに表示される問合せ画面１０１の一例を図８に示す。問合せ画面１０１には、共有化対象領域である作業領域Ａ２と、作業者Ｂが作業した作業領域Ｂ１とが重なり合った状態で表示される。また、問合せ画面１０１には、要求依頼元である作業者Ａから共有依頼があったことを示すメッセージと、共有依頼を許可するか拒否するかを選択するためのＯＫボタン１０２およびＮＯボタン１０３と、送信ボタン１０４とが表示される。共有依頼を許可する場合にはＯＫボタン１０２が選択され、共有依頼を拒否する場合にはＮＯボタン１０３が選択される。 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, a work area A2, which is a sharing target area, and a work area B1 in which the worker B has worked are displayed in an overlapping state. Further, on the inquiry screen 101, a message indicating that a sharing request has been made by the worker A who is the request requester, and an OK button 102 and a NO button 103 for selecting whether to permit or reject the sharing request. , And a send button 104 are displayed. The OK button 102 is selected to allow the sharing request, and the NO button 103 is selected to reject the sharing request.
　作業者Ｂは、ＯＫボタン１０２およびＮＯボタン１０３のうち一方を選択した後、送信ボタン１０４を押す。送信ボタン１０４が押されると（ステップＳ７）、許可・拒否の選択結果が、管理サーバ３に送信される（ステップＳ８）。 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/rejection selection result is sent to the management server 3 (step S8).
　管理サーバ３は、作業者端末２Ｂからの許可・拒否の選択結果を受信すると、選択結果に応じて、テーブル更新処理を行う（ステップＳ９）。 When the management server 3 receives the selection result of permission/rejection from the worker terminal 2B, the management server 3 performs a table update process according to the selection result (step S9).
　ここでは、選択結果が許可であったとする。この場合には、図５Ｂに示すように、管理サーバ３（管理サーバ３の共有化部５４）は、編集・参照権限テーブル４２内の作業領域Ａ２に対応する参照権限の項目に、作業者ＢのＩＤを書き込むとともに、作業領域Ｂ１に対応する参照権限の項目に、作業者ＡのＩＤを書き込む。また、管理サーバ３は、図６Ｂの共有化要求状態テーブル４３の作業領域Ａ２に対する要求依頼先のＩＤから、Ｂを削除する。この結果、共有化要求状態テーブル４３の内容は、図６Ｃのように変化する。 　Here, it is assumed that the selection result is permission. In this case, as shown in FIG. 5B, the management server 3 (sharing 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. The ID of the worker A is written in the reference authority item 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 status table 43 change as shown in FIG. 6C.
　これにより、作業者Ａに作業領域Ｂ１の作業情報の閲覧権限が与えられると同時に、作業者Ｂに作業領域Ａ２の作業情報の閲覧権限が与えられる。 As a result, the worker A is given the authority to browse the work information in the work area B1, and at the same time, the worker B is given the authority to browse the work information in the work area A2.
　管理サーバ３は、更新後の編集・参照権限テーブル４２の内容（更新後の参照権限）を反映した作業者Ｂ専用のＷｅｂページを作業者端末に送信する（ステップＳ１０）。これにより、作業者Ｂは、作業者Ｂ専用のＷｅｂページ上で、作業領域Ａ２の作業情報の閲覧が可能となる。 The management server 3 transmits the Web page dedicated to the worker B, which reflects the content of the updated editing/reference authority table 42 (the updated reference authority) to the worker terminal (step S10). Accordingly, the worker B can browse the work information in the work area A2 on the Web page dedicated to the worker B.
　また、管理サーバ３は、作業者Ａに対して作業者Ａ専用のＷｅｂページを送信する際には、更新後の編集・参照権限テーブル４２の内容（更新後の参照権限）を反映した作業者Ａ専用のＷｅｂページを作業者端末に送信する。これにより、作業者Ａは、作業者Ａ専用のＷｅｂページ上で、作業領域Ｂ１の作業情報の閲覧が可能となる。 Further, the management server 3, when transmitting the Web page dedicated to the worker A to the worker A, reflects the content of the updated editing/reference authority table 42 (the updated reference authority). A Web page dedicated to A is transmitted to the worker terminal. Thereby, the worker A can browse the work information in the work area B1 on the Web page dedicated to the worker A.
　なお、選択結果が拒否であった場合には、管理サーバ３は、編集・参照権限テーブル４２の内容を更新することなく、図６Ｂの共有化要求状態テーブル４３の作業領域Ａ２に対する要求依頼先のＩＤから、Ｂを削除する。 If the selection result is rejection, the management server 3 does not update the contents of the edit/reference authority table 42, and requests the requesting destination of the work area A2 of the sharing request status table 43 of FIG. 6B. Delete B from the ID.
　また、図７Ｂに示すように、この後において、作業者Ｃが、作業者端末２Ｃを操作して、管理サーバ３が提供するホームページを開いた後、ログイン操作を行った場合には（ステップＳ１１）、管理サーバ３は、共有化要求状態テーブル４３に作業者Ｃが要求依頼先として登録されているか否かを判定する（ステップＳ１２）。 Further, as shown in FIG. 7B, when the worker C thereafter operates the worker terminal 2C to open the home page 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 a request request destination in the sharing request state table 43 (step S12).
　この例では、図６Ｃに示すように、共有化要求状態テーブル４３に作業者Ｃが要求依頼先として登録されている。したがって、ステップＳ１２において肯定判定されるので（ステップＳ１２：ＹＥＳ）、管理サーバ３（管理サーバ３の問合せ部５３）は、作業者Ｃに要求依頼元の作業者Ａとの作業情報の共有化を許可するか否を問い合わせるための問合せＷｅｂページを作成して送信する（ステップＳ１３）。 In this example, as shown in FIG. 6C, the worker C is registered in the sharing request status table 43 as a request request destination. Therefore, since an affirmative decision is made in step S12 (step S12: YES), the management server 3 (inquiry section 53 of the management server 3) shares the work information with the worker C who made the request request to the worker C. An inquiry Web page for inquiring whether to permit is created and transmitted (step S13).
　なお、図示しないが、共有化要求状態テーブル４３に作業者Ｃが要求依頼先として登録されていない場合には（ステップＳ１２：ＮＯ）、管理サーバ３は、通常の作業者Ｃ専用のＷｅｂページを作成して作業者端末２Ｃに送信する。 Although not shown, when the 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 the worker C. It is created and transmitted to the worker terminal 2C.
　作業者端末２Ｃは、問合せＷｅｂページを受信すると、問合せ画面を表示する（ステップＳ１４）。作業者端末２Ｃに表示される問合せ画面１１１の一例を図９に示す。 Upon receiving the inquiry Web page, the worker terminal 2C displays the inquiry screen (step S14). An example of the inquiry screen 111 displayed on the worker terminal 2C is shown in FIG.
　問合せ画面１１１には、共有化対象領域である作業領域Ａ２と、作業者Ｃが作業した作業領域Ｃ１およびＣ２とが重なり合った状態で表示される。また、問合せ画面１１１には、作業領域Ｃ１に対して、要求依頼元である作業者Ａから共有依頼があったことを示すメッセージと、共有依頼を許可するか拒否するかを選択するためのＯＫボタン１１２およびＮＯボタン１１３とが表示される。また、問合せ画面１１１には、作業領域Ｃ２に対して、要求依頼元である作業者Ａから共有依頼があったことを示すメッセージと、共有依頼を許可するか拒否するかを選択するためのＯＫボタン１１５およびＮＯボタン１１６とが表示される。さらに、問合せ画面１１１には、送信ボタン１１７が表示される。 On the inquiry screen 111, the work area A2, which is the sharing target area, and the work areas C1 and C2 in which the worker C worked are displayed in an overlapping state. Further, in the inquiry screen 111, a message indicating that there is a sharing request from the worker A, who is the request requester, to the work area C1 and OK for selecting whether to permit or reject the sharing request Button 112 and NO button 113 are displayed. Further, in the inquiry screen 111, a message indicating that there is a sharing request from the worker A, who is the request requesting source, to the work area C2, and OK for selecting whether to permit or reject the sharing request Button 115 and NO button 116 are displayed. Further, a send button 117 is displayed on the inquiry screen 111.
　作業者Ｃは、作業領域Ｃ１に対して、ＯＫボタン１１２およびＮＯボタン１１３のうち一方を選択する。また、作業者Ｃは、作業領域Ｃ２に対して、ＯＫボタン１１５およびＮＯボタン１１６のうち一方を選択する。この後、作業者Ｃは、送信ボタン１１７を押す。送信ボタン１１７が押されると（ステップＳ１５）、作業領域Ｃ１に対する許可・拒否の選択結果と、作業領域Ｃ２に対する許可・拒否の選択結果が、管理サーバ３に送信される（ステップＳ１６）。 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. Then, the worker C presses the send button 117. When the send button 117 is pressed (step S15), the selection result of permission/rejection for the work area C1 and the selection result of permission/rejection for the work area C2 are transmitted to the management server 3 (step S16).
　管理サーバ３は、作業者端末２Ｃからの許可・拒否の選択結果を受信すると、選択結果に応じて、テーブル更新処理を行う（ステップＳ１７）。 When the management server 3 receives the selection result of permission/rejection from the worker terminal 2C, the management server 3 performs a table update process according to the selection result (step S17).
　ここでは、作業領域Ｃ１に対する選択結果が拒否であり、作業領域Ｃ２に対する選択結果が許可であったとする。この場合には、図５Ｃに示すように、管理サーバ３（管理サーバ３の共有化部５４）は、編集・参照権限テーブル４２内の作業領域Ａ２に対応する参照権限の項目に、作業者ＣのＩＤを書き込むとともに、作業領域Ｃ２に対応する参照権限の項目に、作業者ＡのＩＤを書き込む。また、管理サーバ３は、図６Ｃの共有化要求状態テーブル４３の作業領域Ａ２に対する要求依頼先のＩＤから、Ｃを削除する。この結果、共有化要求状態テーブル４３の内容は、図６Ｄのように変化する。 Here, it is assumed that the selection result for the work area C1 is rejection and the selection result for the work area C2 is permission. In this case, as shown in FIG. 5C, the management server 3 (sharing unit 54 of the management server 3) selects the worker C in the reference authority item corresponding to the work area A2 in the editing/reference authority table 42. The ID of the 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 in the sharing request status table 43 of FIG. 6C. As a result, the content of the sharing request status table 43 changes as shown in FIG. 6D.
　これにより、作業者Ａに作業領域Ｃ２の作業情報の閲覧権限が与えられると同時に、作業者Ｃに作業領域Ａ２の作業情報の閲覧権限が与えられる。 As a result, the worker A is given the authority to browse the work information in the work area C2, and at the same time, the worker C is given the authority to browse the work information in the work area A2.
　管理サーバ３は、更新後の編集・参照権限テーブル４２の内容（更新後の参照権限）を反映した作業者Ｃ専用のＷｅｂページを作業者端末に送信する（ステップＳ１８）。これにより、作業者Ｃは、作業者Ｃ専用のＷｅｂページ上で、作業領域Ａ２の作業情報の閲覧が可能となる。 The management server 3 transmits the Web page dedicated to the worker C, which reflects the content of the updated editing/reference authority table 42 (updated reference authority) to the worker terminal (step S18). Thereby, the worker C can browse the work information of the work area A2 on the Web page dedicated to the worker C.
　また、管理サーバ３は、作業者Ａに対して作業者Ａ専用のＷｅｂページを送信する際には、更新後の編集・参照権限テーブル４２の内容（更新後の参照権限）を反映した作業者Ａ専用のＷｅｂページを作業者端末に送信する。これにより、作業者Ａは、作業者Ａ専用のＷｅｂページ上で、作業領域Ｂ１およびＣ２の作業情報の閲覧が可能となる。 Further, the management server 3, when transmitting the Web page dedicated to the worker A to the worker A, reflects the content of the updated editing/reference authority table 42 (the updated reference authority). A Web page dedicated to A is transmitted to the worker terminal. Thereby, the worker A can browse the work information of the work areas B1 and C2 on the Web page dedicated to the worker A.
　なお、作業領域Ｃ１に対する選択結果および作業領域Ｃ２に対する選択結果が共に許可であった場合には、管理サーバ３は、編集・参照権限テーブル４２内の作業領域Ａ２に対応する参照権限の項目に、作業者ＣのＩＤを書き込むとともに、作業領域Ｃ１およびＣ２に対応する参照権限の項目に、作業者ＡのＩＤを書き込む。また、管理サーバ３は、図６Ｃの共有化要求状態テーブル４３の作業領域Ａ２に対する要求依頼先のＩＤから、Ｃを削除する。 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 editing/reference authority table 42 as follows. The ID of the worker C is written, and the ID of the worker A is written in the item of 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 in the sharing request status table 43 of FIG. 6C.
　なお、作業領域Ｃ１に対する選択結果および作業領域Ｃ２に対する選択結果が共に拒否であった場合には、管理サーバ３は、編集・参照権限テーブル４２の内容を更新することなく、図６Ｃの共有化要求状態テーブル４３の作業領域Ａ２に対する要求依頼先のＩＤから、Ｃを削除する。 If both the selection result for the work area C1 and the selection result for the work area C2 are rejects, the management server 3 does not update the contents of the editing/reference authority table 42 and requests the sharing of FIG. 6C. C is deleted from the ID of the request request destination for the work area A2 in the state table 43.
　ステップＳ２で作成された共有化要求状態テーブル４３のデータは、その後の更新の有無にかかわらず、有効期限が切れた時点で削除される。 The data in the sharing request status table 43 created in step S2 is deleted when the expiration date expires, regardless of the presence or absence of subsequent updates.
　前述の実施形態によれば、少なくとも一部が重なる領域において異なる作業者が異なる期間において作業を行った場合に、異なる作業者間での作業情報の共有化が、作業者間の同意を条件として可能となる。これにより、作業者は、自己が作業を行った作業領域と少なくとも一部が重なる領域において、他の作業者がどのような作業を行ったかを知ることが可能となる。 According to the above-described embodiment, when different workers perform work in different periods in at least a part of overlapping areas, sharing of work information between different workers is subject to agreement between the workers. It will be possible. This allows the worker to know what kind of work another worker has performed in a region at least partially overlapping with the work region in which the worker has performed the work.
　以上、この発明の実施形態について説明したが、この発明はさらに他の形態で実施することもできる。例えば、前述の実施形態では、作業情報は、作業名、作業機械、作業時の測位情報、ポリゴン、作業面積、作業開始・終了時刻および作業コストからなるが、これらは一例であって、これらに限られない。 The embodiments of the present invention have been described above, but the present invention can be implemented in other forms. For example, in the above-described embodiment, the work information includes work name, work machine, positioning information at work, polygon, work area, work start/end time, and work cost. Not limited.
　また、前述の実施形態では、ある作業領域に対して参照権限が与えられた作業者は、その作業領域の作業情報の全てを閲覧可能であった。しかし、ある作業領域に対して参照権限が与えられた作業者に対して、作業領域の作業情報の一部のみ閲覧可能とするようにしてもよい。つまり、参照権限によって閲覧が可能となる作業情報に制限をかけてもよい。 Further, in the above-described embodiment, a worker who is given reference authority to a certain work area can browse all work information of the work area. However, a worker who is given reference authority to a certain work area may be allowed to view only a part of the work information of the work area. That is, the work information that can be browsed by the reference authority may be restricted.
　このような閲覧可能な作業情報への制限は、管理サーバ３側で設定してもよい。また、このような閲覧可能な作業情報への制限は、ある作業者が作業情報の共有化を要求する際に、当該作業者が設定するようにしてもよい。この場合には、共有化要求毎に共有化要求元の作業者が制限内容を設定することが可能となる。 The limitation on the work information that can be browsed may be set on the management server 3 side. Further, such a restriction on the work information that can be browsed may be set by a certain worker when a certain worker requests sharing of the work information. In this case, the sharing request source worker can set the limitation content for each sharing request.
　また、前述の実施形態では、各作業者端末２Ａ，２Ｂ，２Ｃは、パーソナルコンピュータ（ＰＣ）から構成されているが、各作業者端末２Ａ，２Ｂ，２Ｃは、スマートフォンから構成されていてもよい。 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. ..
　本発明の実施形態について詳細に説明してきたが、これらは本発明の技術的内容を明らかにするために用いられた具体例に過ぎず、本発明はこれらの具体例に限定して解釈されるべきではなく、本発明の範囲は添付の請求の範囲によってのみ限定される。 Although the embodiments of the present invention have been described in detail, these are merely specific examples used for clarifying the technical content of the present invention, and the present invention is construed as being limited to these specific examples.
