As shown in FIG. 5, the tree structure data includes a service node 51 in the hierarchy 1 defined by the service provider side, site management nodes 52 and 53 in the hierarchies 2 and 3 that perform necessary definitions for each site management, It is composed of a level 4 facility management node 54 and the like for performing necessary definitions for each management. The overall hierarchical structure and the number of hierarchies of each node can be freely set, and the internal data for each hierarchy can be freely selected and set from the management items of FIGS. For example, in the service node 51, the site management ID 51a, the service name 51b, the link address 52c of the child node, etc. are set. Each subordinate node is created by tracing from the service node 51 as a parent node, so that the management structure can be changed for each service provider. For example, in FIG. 5 (a), there is only one on-site management node in the hierarchy 2, but if necessary, the number of nodes in the hierarchy 2 can be two as shown in FIG. 5 (b).

  The tree structure data for each service exists in series in the same memory area in the tree structure data storage unit 44 as shown in FIG. For example, the service node 51 in the hierarchy 1 in FIG. 5A is stored like the service node block 51 in the data structure block in FIG. A node address “N00” block 51a corresponding to the site management ID 51a and a service name block 51a corresponding to the service name 51b are provided, and a child node address “N1001” block 51c which is a link address 51c of the child node is provided below the block 51a. . The blank block usually contains tree data for other services, but all nodes have parent node information, so data management is hindered even if they are arranged in series in the memory area. There is no. By not providing a frame in the memory area in this way, the entire memory area can be used effectively.

  The remote monitoring server control unit 31 receives a request from the user, and executes the target application processing unit 33. Further, the user management authentication processing unit 32 is requested to control whether the user can access the application.

  The user management authentication processing unit 32 performs authentication processing when the user logs in and logs out of the site monitoring system. In addition, the access right to each application, data access, and access right to the facility management unit 35 are controlled.

  The application processing unit 33 executes various programs (applications) for providing services. The application creator uses the task management unit 34, the facility management unit 35, and the data access processing unit 36 to create a plurality of processing logics. This processing logic can be created individually according to a plurality of different user requests, for example, a restaurant request, a telephone company request, and the like.

  The task management unit 34 executes task processing that cannot be executed as a Web application such as the application processing unit 33. The task management unit 34 is a part of the remote monitoring server 3 in FIG. 2, but may exist as a separate device. The task management unit 34 is not only activated when a task is requested and outputs the result, but also has a function of activating and storing a plurality of tasks, a function of activating according to a schedule, and an automatic restart function in case of an abnormality. .

  The facility management unit 35 manages the sites managed by the site monitoring system 100 in a hierarchical manner. The equipment management unit 35 can also manage hierarchies of signals other than the site as equipment, and in order to perform this management operation, a tree structure creation means 35a, a new registration means 35b, an update means 35c, a display means 35d, a search means 35f and deletion means 35e.

  The tree structure creating means 35a reads necessary data from the data holding server 4 and constructs the tree structure data shown in FIGS. 5 and 6 for each piece of information required by the user.

  The new registration unit 35b newly registers the tree structure data in the tree structure data storage unit 44. The updating unit 35c updates the tree structure data. The display means 35d outputs the tree structure data on the output device 38. The search means 35f searches for necessary data from the tree structure data in accordance with a user request. The deleting unit 35e deletes unnecessary data in the tree structure data.

  The data access processing unit 36 passes the time series data (analog value), alarm, and digital data (digital input DI, digital output DO) of each signal to the application processing unit 33. As data access arguments, information in the user information table 41a in FIG. 3 and signal IDs in the signal management table 42e are used. In the data access, the facility management unit 35 and the user management authentication processing unit 32 are used to determine whether the user who has requested the data has an access right to read or write data. If the service provider to which the user belongs is different, the data access processing unit 36 locks the data so that information is not leaked to other users, and security is maintained. Data access can be plugged in, and even if data transmission / reception and access methods differ from site to site, it can be handled.

  The input device 37 is an interface that receives an input signal from a keyboard, a mouse, or the like. It may be input via an external storage device such as a floppy (registered trademark) disk or hard disk. The output device 38 is a device for outputting tree structure data, analysis results, and the like, and specifically refers to a liquid crystal display, a CRT display, a printer, and the like. The communication control device 39 generates a control signal for transmitting / receiving data to / from another device. The main storage device 40 temporarily stores a program describing a processing procedure and data to be processed as a main memory, and delivers a machine instruction and data of the program according to a request from the CPU 30. Data processed by the CPU 30 is written to the main storage device 14. The main storage device 14 and the CPU 30 are connected by an address bus, a data bus, a control signal, and the like.

(Operation of on-site monitoring system)
Next, the overall operation of the site monitoring system 100 will be described with reference to the flowchart of FIG.

(A) In step S101, the on-site monitoring devices 8a and 8b monitor the connected devices 9a to 9d to be monitored. The on-site monitoring devices 8a and 8b perform monitoring setting for each monitoring target such as a refrigerator, lighting, generator, and air conditioner. For example, when the connected device is a refrigerator and lighting, the monitoring data is transmitted to the on-site monitoring devices 8a and 8b only when the temperature of the refrigerator is detected every hour and when an abnormality is detected with respect to lighting. The on-site monitoring devices 8a and 8b appropriately receive these monitoring data and transmit the data to the on-site communication control devices 7a and 7b.

(B) In step S102, the on-site communication control devices 7a and 7b transmit the monitoring data to the central gateway device 5 on the center side via the communication network 6. The central gateway device 5 receives this monitoring data and creates data that is the basis of this tree structure. For example, as shown in FIG. 5, when the service A of a convenience store or the service B of a restaurant B holds service information as a parent node, the child node is “field information” and the grandchild node is “equipment management information”. The upper node information is added so that it can be identified. As a result, the upper node information is always attached to the head of the lower node information, and the higher the node information, the larger the amount of upper node information added.

(B) In step S <b> 103, the central gateway device 5 delivers the tree structure base data to the remote monitoring server 3. Next, user authentication processing by the user management authentication processing unit 32 of the remote monitoring server 3 of FIG. 2 is performed, and tree structure data creation by the tree structure creation means 35a of the facility management unit 35 is performed. Details will be described later.

(C) In step S104, the created tree structure data is presented on the information display terminal 1 of FIG. 1, and processing such as new registration, update, display, search, and deletion is performed according to a user request.

(Operation for creating tree structure data of remote monitoring server)
Hereinafter, the operation of the remote monitoring server 3 when creating the tree structure data in step S103 will be described in detail with reference to the flowchart of FIG.

(A) In step S201, when the remote monitoring server control unit 31 in the CPU 30 in FIG. 2 receives a request for creating tree structure data from the user, the user management authentication processing unit 32 performs the user affiliation for user authentication. Get permission. Furthermore, in step S202, the user inputs the equipment management ID for which the user wants to perform the tree structure data creation processing via the input device 37 of FIG. The facility management ID is any one of the service ID, the site management ID, the facility ID, and the signal ID in FIG. In step S203, the user management authentication processing unit 32 checks whether or not the user has the authority to belong and the authority to manage the equipment. The affiliation authority and equipment management authority may be checked individually at the time of acquisition. The affiliation authority check is performed based on the user information table 41a of the user management information storage unit 41 of FIG. 4, and the facility management authority check is performed based on the ownership authority management table 41b of FIG. If the user does not have the affiliation authority and the facility management authority, this process is terminated.

(B) In step S204, the facility management unit 35 extracts a service name based on the service ID in the service management table 42a of FIG. In step S205, preparation is made for creating data relating to the service as a hierarchy, that is, tree structure data. The hierarchy is represented by N and has an initial value of 0, and the hierarchy increases by 1 for each loop. That is, the hierarchy is deeper and goes from the upper node to the lower node. The hierarchy may be different for each service handled. For example, the A service performed by the A convenience store may be tree-structured data of five layers, and the B service performed by the B restaurant may be tree-structured data of three layers.

(C) In step S206, the tree structure creation unit 35a in FIG. 2 searches the stage N of the site management table 42b in FIG. 3 based on the service ID and the parent site management ID. In step S207, it is determined whether or not the search result of the stage of level N is 0. If there are one or more search results, the process proceeds to step S208. If there is no search result, it is determined that the tree structure data creation processing has been completed at the stage of the immediately preceding hierarchy N-1, and there is no other data to select. If so, this process ends.

(D) In step S208, a search result is added for each element of the facility management ID to be acquired. In step S209, the field management ID of the first record in the search result is retrieved and set as the parent field management ID. For example, the site management ID 51 a of the “service” node 51 in FIG. 5 is the parent site ID of the site management 1 node 52, and the site management ID 52 a of the site management 1 node 52 is the parent site ID of the site management 2 node 53.

(E) When the association between the service node 51 (parent) in FIG. 5 and one or more site management nodes 52 and 53 (child) is completed in this way, in step S210, the element of the facility management node that becomes the grandchild node Is stored. Details will be described later.

(F) The processing of S205 to S210 is performed for all the hierarchies N, and when the creation of the tree structure data for all the nodes is completed, the tree structure creation means 35a finishes this program processing.

  Next, the facility management node creation process in step S210 will be described in detail with reference to the flowchart of FIG.

(A) In step S301, the tree structure creation unit 35a in FIG. 2 causes the user to input the site management ID for which the tree structure data creation process is to be performed via the input device 37 in FIG. 2, and acquires this as facility information. . In step S302, preparation is made for creating data relating to facility management as tree structure data. The hierarchy value N, the initial value 0, and the hierarchy increase by 1 for each loop.

(B) In step S303, the tree structure creation unit 35a searches for the stage of the hierarchy N in the equipment management table 42d of FIG. 3 based on the site management ID and the parent equipment management ID. In step S304, it is determined whether or not the search result of the stage of level N is zero. If there are one or more search results, the process proceeds to step S305. If there is no search result, it is determined that the tree structure data creation processing has been completed at the stage of the immediately preceding hierarchy N-1, and there is no other data to select. If so, this process ends.

(C) In step S305, a search result is added for each element of the facility management ID to be acquired. In step S306, the equipment ID of the first record in the search result is searched and set as the parent equipment ID. For example, the equipment ID in the link address 53 c of the child node of the site management 2 node 53 in FIG. 5 becomes the parent equipment ID of the equipment management node 54.

(D) When the association between the child node and one or more facility management nodes 54 (grandchild) is completed in this way, in step S307, the signal management table 42e of FIG. 3 is searched based on the facility ID, and the result Is stored as an element.

(E) The processing of S302 to S307 is performed for all the hierarchies N, and when the creation of the tree structure data for all the nodes is completed, the tree structure creation means 35a returns to step S205.

Judging. If it is a parent hierarchy display request, the process proceeds to step S403, and if it is not a parent hierarchy display request, the process proceeds to step S404.

(B) In step S403, the parent data ID of the currently displayed hierarchy N and the hierarchy information corresponding to the hierarchy N-1 are acquired. In step S404, the child data ID of the current display hierarchy and the hierarchy information corresponding to the hierarchy N + 1 are acquired.

(C) In step S405, the display unit 35d acquires the tree structure data of the target hierarchy from the tree structure data storage unit 44 and displays it on the output device 38 of FIG.

  The deletion operation will be described with reference to the flowchart of FIG.

(A) In step S501, when the deletion unit 35e acquires a tree structure data deletion request from the user via the input device 37 of FIG. 2, in step S502, the deletion unit 35e displays an ID list to which the data ID requested by the user belongs. get.

(B) In step S503, the link from the parent node to which the requested data ID belongs is deleted. In step S504, the device-specific information and the clause information corresponding to the data ID list are deleted from the data holding server 4.

(C) In step S505, the tree structure creation unit 35a creates tree structure data again as necessary.

  The update operation will be described with reference to the flowchart of FIG.

(A) In step S601, when the updating unit 35c obtains a tree structure data update request from the user via the input device 37 in FIG. 2, in step S602, the update unit 35c updates the data holding server 4 that matches the requested data ID. Change the table to be retained.

(B) Further, in step S603, the location to be updated in the tree structure data is updated.
