479176 A7 --------B7 五、發明說明（1 ) 〔發明所屬技術領域〕 (請先閱讀背面之注意事項再填寫本頁) 本發明有關複數個客戶器（Cllent )編輯伺服器（ Seiver )所控制的負料的主從式伺服系統（ciient/Server System )，特別是有關爲進行複數個客戶器之間的編輯資 料之排他控制（exclusive contr〇i )及同步（統一）之用的 技術。 經濟部智慧財產局員工消費合作社印製 例如，設想複數個客戶器將分頭進行編輯伺服器所控 制的地甲資料（例如客戶器A描寫道路A，客戶器B描寫 道路B之分別方式）的情形。關於複數個客戶器同時在進 行的編輯處理，伺服器必須保證其整合性及統一性。例如 ’從伺服器對客戶器P及客戶器Q同時提供如第丨圖（A )的地圖資料’客戶器P將如同圖（B )般進行道路 1〇0之編輯處理，客戶器Q則如同圖（C )般進行道路 2 0 0之編輯處理的情形，爲反映客戶器p、Q之各個意 思起見，伺服器必須如同圖（D )般認識最終結果並將其 最終結果亦讓各客戶器P、Q知道（編輯資料之同步亦即 統一）。又，對客戶器P所進行的編輯結果與客戶器Q所 進行的編輯結果已經整合，亦即，不會互相矛盾（例如客 戶器P、Q對同一道路1 0 〇不會同時編輯爲不同型態之 方式）之事實亦必須予以保證（編輯資料之整合性）。 因此，通常，伺服器將全資料分爲複數個資料群管理 ’進行對一個資料群僅分配一個客戶器的方式之排他控制 。亦即，伺服器對本身爲客戶器P之編輯對象的資料群， 以防止客戶器Q進行編輯之方式予以鎖定（lock )，待客 -4 -

Description of the invention (1) [Technical field to which the invention belongs] (Please read the notes on the back before filling out this page) The invention relates to a plurality of client (Cllent) editing servers (Seiver) controlled master-slave servo system (ciient / Server System), especially for the exclusive control (exclusive contr0i) and synchronization (unification) of editing data between multiple clients Used technology. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs situation. Regarding the editing process performed by multiple clients at the same time, the server must ensure its integration and uniformity. For example, 'from the server to the client P and the client Q at the same time as the map (A) map data' client P will be as shown in the map (B) edit road 100, client Q is as In the case of editing the road 2 0 as shown in Figure (C), in order to reflect the meanings of the clients p and Q, the server must recognize the final result as shown in Figure (D) and let the client to the final result. The controllers P and Q know (the synchronization of editing data is unified). In addition, the editing results performed by the client P and the editing results performed by the client Q have been integrated, that is, they will not contradict each other (for example, the client P, Q will not be edited into different types at the same time on the same road 100). State of affairs) must also be guaranteed (integrity of editing data). Therefore, in general, the server divides the entire data into a plurality of data group managements, and performs exclusive control of a method of allocating only one client to a data group. That is, the server locks the data group that is the editing object of the client P in order to prevent the client Q from editing, waiting for the guest-4-This paper standard applies to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 479176 A7 B7 V. Description of the invention (2) After the editing process of the client P is finished, the lock is released, so that it can become the editing target of the client Q. [Problems to be Solved by the Invention] The extent to which the volume of the data group that becomes one unit of the above-mentioned exclusive control is set is a major issue that affects the efficiency or ease of use of editing operations. For example, in the case of a map editing application, the entire map image can be divided into meshes according to a certain longitude and latitude in advance, and all graphics and text data existing in one of the meshes can be used as exclusive control. 1 unit. However, in this case, for example, a client machine starts to edit the graphics of most meshes like a long-distance railway. Before the editing is completed, other client machines cannot start the majority of its meshes, so that in fact, work cannot progress Problem. If you want to solve this problem, you can make the individual roads or buildings on the map as the unit of exclusive control (that is, you can use it as the minimum information that is not suitable for subdivision and editing). However, in such a way that the units under exclusive control are made small, it is necessary to generate and retrieve the graphic data from the map data managed as a data base. If the database is large, it will take a lot of time for this retrieval to cause the problem of poor operation efficiency. Furthermore, in the conventional master-slave servo system, the client notifies the server of the content of the editing process to be executed each time it executes each editing process. The server determines whether the notified editing process is allowed, and if it is allowed, updates the database according to its content, and then transfers the update result back to the client. The client machine receiving the updated result will reflect its update on its own application. This paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) _ 5-(Please read the precautions on the back before filling this page ) ¾ II ---------. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 479176 A7 B7 V. Description of Invention (3) Results. The server also notifies each client other than the client that has notified the editing process of the update result. Each client that receives the update result reflects its update result on its own application. In short, the client only communicates with the server for various notifications, and the actual editing process is performed under the guidance of the server. Therefore, if the number of clients increases, the amount of processing required for the server will increase and the burden on the server becomes very large. In addition, before the results of the editing process are reflected on the application of each client, there are various requests or notifications between the client and the server. It takes a lot of time to process them, and the editing results are reflected to others. The client takes a lot of time. Therefore, an object of the present invention is to provide a master-slave servo system in which each client can perform editing operations with good efficiency. Another object of the present invention is to provide a master-slave servo system that reflects the operation results of individual clients to other clients at a higher speed. [Method for Solving the Problem] The master-slave servo system according to the first aspect of the present invention includes: a lock list (丨 cked 1 ist) of cataloged objects whose objects have been determined because any client is being edited. ; Refer to its lock list, and notify the client's notification department of the fact that the objects that each client wishes to edit are locked. According to this, the client that has been notified only makes the unlocked object editable. The master-slave servo system of the second aspect of the present invention is that the paper size of the server is applicable to the Chinese National Standard (CNS) A4 (210 X 297 mm). 6 (Please read the precautions on the back before filling this page ) --------- Order --------- line 'Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 479176 A7 B7 V.

For example, 'can be used as the user can operate the mouse, and on the display, the cursor is placed on the desired object and the mouse button is pressed to designate the object to be edited. If the object is designated as the editing object, the client 3 a transmits the graphic 5 tiger code of the designated object to He Fu Po 1 and asks whether the object can be locked (s 7). The control unit 4 of the server 1 will refer to the graphic lock directory 1 1 and judge whether the inquired object can be locked (S 8). That is, the control section 4 will refer to the graphic lock directory 1 1 'as inquired from the client 3 a-11-this paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 76 A7 ---- -------- B7_ V. Description of the invention (9) (Please read the notes on the back before filling in this page) Objects on the graphics lock directory 1 1 indicate other clients (customer benefits 3 a Clients other than the client) are editing their objects, and judge that the client 3a cannot be edited, and transmit the figure number of the object and the fact that they cannot be locked (that is, cannot be edited) to the client as locked information Device 3 a (S 1 0). "If the object inquired from the client is not on the graphics lock: f directory 1 1", it means that no other user is editing the object. The control unit 4 will determine that the client 3 a can edit and lock the graphics. The directory 11 writes the figure number of its object (s 9), and transmits the figure number of its object and the fact that it can be locked (that is, editable) as lock information to the client 3 a (S 1 〇) . In this action of confirming whether the lock can be confirmed, “Just look at the lock list 11 of the graphic number of the locked object, and judge whether the lock is possible. It ’s the same as the past retrieval of the lock to be confirmed from the enlarged database. The comparison of the methods of the data can determine the lockability in a very short time. The consumer property cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs prints the client device 3 a to obtain the lock information from the server 1 (s 1 1) 'For the objects that are considered to be lockable, create an editable mode (S 1 2) . For example, it can be used as a client device 3 a to invert the display of objects that can be locked on the display, so as to indicate to the user that it can be edited, and not to reversely display objects that cannot be locked. A method of notifying the user by displaying a message such as "Cannot be edited" on the monitor. If the designated object is an editor, the user will perform various editing functions on the object (S 1 3).

Description of Invention (ίο) Changes, additions, deletions, etc. Secondly, the client 3a will judge whether the editing operations of the related objects being edited by the user are all completed (S 1 4). For example, if the user is editing a building on the map, if the user designates something other than his building, or when he finishes the operation of the map editing application, etc., the client 3a will judge the building. Editing of objects has all ended. If the editing job is not finished, the process returns to step S 1 3, and the user will continue to edit the job. If the editing operation is terminated, if the user wants to edit another object, the process returns to step S6 and a new object is designated. In parallel with this, the edit record creation unit 21a creates an edit record of an object that has just ended as an edit record file (S 1 5). The records stored in the edit log file here only represent the difference records of the change points according to the editing process, not the edited image log (image log) of the edited object itself. Then, the client 3a transmits the created edit file to the server 1 (S 1 6). The control unit 4 of the server 1 receives the transmitted edit record file (S 1 7) and sends it to the edit record analysis unit 13. The control unit 4 updates the content of the main file 9 (that is, updates the equivalent object to the edited state) based on the analyzed content (S 1 9). Accordingly, synchronization (unification) between the client 3a and the server 1 can be performed. In addition, the control unit 4 can synchronize the entire master-slave servo system (system k) (S 2 2) by assigning this edited record file to a client other than the client 3a.: ,, .

Description of the invention (11). On the one hand, the 'client 3a' will terminate the editing operation, decide to release the lock (S 1 9), and transmit the figure number of the object and the meaning of the unlocking to the server (s 2 0) as the lock information. The control unit 4 of the server 1 receives the lock information and deletes the figure number of the object shown in the lock information from the figure lock list 1 1 (S 2 2). Fig. 4 shows a processing flow for synchronizing the master-slave servo system to the entire system after step S 2 · 2 of Fig. 3. The control unit 4 of the server 1 logs in to the client 1 of the server 1 (hereinafter referred to as a client 3) for a client other than the client 3a (ie, the client 3 b ...) which transmits the edited record file. Log into the client) and ask if the map editing application has been launched (S 3 1). If each login client receives an inquiry (S 3 2) from the server 1, the answer to its inquiry is transmitted to the server 1 (s 3 3). The server determines whether a map editing application has been started for each login client based on its response (S 3 4). Next, the control section 4 transmits the edit record file received from the client 3 a only to the login client whose answer is A Yes (that is, the map editing application is started) (S 3 5). The editing record creation section 21 of the login client that has taken the edit record file will analyze the edit record file, and the login client will update the content of the local file 19 according to the parsed content. If the answer is “No” (that is, the map editing application is not started), the operation of the control section 4 is terminated. In this case, the login client without the map editing application started, and later the map paper 7 & used Chinese National Standard (CNS) A4 specification (210 X 297 mm) · 14-(Please read the precautions on the back first (Fill in this page again.) -------- Order -------.--- Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 479176 A7 --- B7 V. Description of the invention (12) Editing application When the program requests to edit the map data of the desired area, as explained in step S 3 of FIG. 3, the server will read the corresponding map file from the main file 9 and transfer it to its login client. Since the content of the file it transmitted was updated in step S 2 1 in FIG. 3, the content of the updated file in step S 4 in FIG. 3 will be reflected to the local file 19. For the client that has not logged into the server 1 at step S 31, as described above, when the map editing application is launched later, the content of the updated file in the main file 9 will be reflected to the local File 9. Due to the above actions, this master-slave servo system will synchronize (unify) the map data with the entire system. The above 'has described the preferred embodiment of the present invention, but the above embodiment is merely an illustration for the purpose of explaining the present invention, and is not intended to limit the scope of the present invention to this embodiment only. Those skilled in the art can implement the present invention in various other forms such as deformation, improvement, correction, and simplification in the above embodiment without departing from the gist of the present invention. For example, the configuration of the master-slave servo system is not limited to the centralized server-type master-slave servo system described above, but may be a distributed server-type master-slave servo system having a plurality of servers. In addition to the map editing application, this master-slave servo system can also be used in various applications such as an article making application or a table calculation application.
