Description

  The present invention relates to a change management analysis method, a change management analysis apparatus, and a change management analysis program. Specifically, it is possible to quickly and efficiently provide a user with impact information on installation layout changes in an entrance / exit management system. Regarding technology.

The entrance / exit management system plays a central role in physical security in security measures in companies and organizations. Prior to the introduction of such an entry / exit management system, physical locks were attached to the entrances of buildings and doors of rooms, and the keys to open the locks were managed by the general affairs department or guardhouses. In this case, passers-by often filled out the ledger and rented and returned the keys. On the other hand, after the introduction of the entrance / exit management system, an authentication device is installed at the entrance of the building, the door of the room, etc., and non-contact IC cards are distributed to the passers-by in advance, and the passers-by are as shown below. Came to limit.
・ Install a numeric keypad and unlock the door when a specified secret code is entered.
・ A non-contact IC card reader is installed, and the door is unlocked when a predetermined IC card is held over.
-Install biometrics sensors (fingerprints, veins, faces, irises, voiceprints, etc.), and unlock doors when given biometrics are presented.
・ When an intercom is prepared and the secretary in the room determines that the person is the correct passerby through conversation, the door is unlocked by pressing the unlock button.

  Such an entrance / exit management system is installed according to the layout of buildings and rooms, and the required security level. The layout of buildings and rooms is different for each company and organization, and the entrance / exit management system can be installed flexibly according to such various layouts. In addition, depending on the security level of the building or room to be protected, there are various authentication means to be applied, such as when a secret code authentication means such as a personal identification number is used or when a strict authentication means such as biometrics is adopted.

  As such entry / exit management technology, for example, authentication with each of a plurality of card readers is performed on each card for the purpose of realizing entrance / exit management through various entrance / exit routes according to entrance / exit conditions. The combination of the assigned ID code and the unlock flag set for each of the individual cards and the individual card readers determines whether to permit or disallow entry / exit, and There has also been proposed an entrance / exit management method (see Patent Document 1), which dynamically changes the setting state of the lock flag in accordance with the entrance / exit status of the card owner.

  Further, a room layout file in which a recognition place where each recognition device is attached and another recognition place that can be directly moved from the recognition place are associated in advance, and a room file in which a predetermined room where each user should be registered is registered. Measured recognition information measured by the recognizing device and missing measurement (recognition information that should have been originally obtained due to card reading failure or companion cannot be obtained in the entrance / exit management system) A recognition information file for storing the recognition information, an occupancy status file for storing the latest recognition location of each user, and whether or not the latest recognition location can be directly moved from the previous recognition location. A determination is made with reference to the room layout file, and the missing recognition device on the movement route estimated based on the room layout file is detected only when the movement is impossible. In addition to setting the information, if the latest recognized place is other than the predetermined room, when the predetermined time has passed without being recognized next, the predetermined room is estimated to be the latest recognized place. An entrance / exit management device (see Patent Document 2) characterized by including a processing device that sets a recognition device that is missing at the latest recognition location as the missing recognition information has also been proposed. .

  However, if the installation layout of the entrance / exit management system can be configured with high flexibility, the user can grasp the affected area, affected area, affected contents, etc. when changing the entire system or a part of the system. It becomes difficult.

For example, in the current situation, entrance / exit management is performed for only one floor in a building, but in a situation where entry / exit management is performed for all floors in a building by changing this, the building tenant differs from floor to floor = It is difficult for the user to quickly and efficiently grasp the scope of management authority change management and the like in the entrance / exit management system, taking into consideration that the scope of authority for exit management is different.
Also, for example, when a card reader used for entrance / exit management is changed to a biometric authentication device for security enhancement, the user can quickly and efficiently know which device should be changed and how. It is difficult.
In addition, for example, when some equipment in the entrance / exit management system breaks down, the user has information such as what kind of influence is caused and how far the affected area is, and which equipment should be suspended when repairing. It is difficult to grasp quickly and efficiently.
In other words, when the installation layout is configured with high flexibility regarding the entrance / exit management system, information to be grasped by the user is not provided promptly and efficiently.

--- Example 1 ---
Hereinafter, embodiments of the present invention will be described with reference to the drawings as appropriate. FIG. 1 is a diagram showing an entire system including a change management analysis apparatus 1. The change management analysis apparatus 1 is an apparatus that analyzes an influence or the like when changing the configuration of an entrance / exit management system 10 installed in a building such as a company, and assumes an information processing apparatus such as a PC. To do.

  The change management analysis device 1 is a terminal operated by a change manager 30 such as an administrator of the entrance / exit management system 10 or a salesperson who proposes a change of the entrance / exit management system 10 to the manager. Since this terminal is likely to exert great power in business activities related to the entrance / exit management system 10, it is more preferable that the terminal be portable. The change management analyzer 1 is assumed to be connected to the entrance / exit management system 10 through the communication line 41 so as to be communicable and further connected to the Internet 20 through the communication line 40. Of course, the type of network and the communication protocol are not questioned.

  On the other hand, the entrance / exit management system 10 is an existing computer system having a configuration information table 11, a schedule table 12, and an authentication information table 13. The entrance / exit management system 10 uses these tables 11 to 13 to issue an operation command to a door opening / closing mechanism, locking / unlocking, or the like so as to appropriately limit passers-by entering and exiting the building or room.

  On the Internet 20, a situation is assumed in which the change scenario table 21, the operation scenario table 22, and the product information table 23 are managed by a development vendor or a maintenance vendor of the entry / exit management system 10. Further, the map information table 24 is a table storing map data of buildings and the like that are operated by the entrance / exit management system 10, and is map information that can be used on the Internet 20. Of course, copies of these tables 21 to 24 may be held and managed in the storage unit 203 of the change management analyzer 1 periodically or irregularly. The location of the tables 21 to 24 is not limited as long as the change management analyzer 1 can access.

  FIG. 2 is a block diagram showing the internal structure of the change management analysis apparatus 1. Then, the structure and function with which the change management analyzer 1 is provided are demonstrated. The change management analysis apparatus 1 is a CPU (Central Processing Unit) 201 that is a central processing unit that controls the apparatus and calculates and processes data, and is provided as an information processing apparatus, and temporarily stores data and programs. Can be directly read / written, a non-volatile storage unit 203 that stores data and programs so that data and programs are not lost even when the power is turned off, and communication with the communication line 40 or the communication line 41 in a wired or wireless manner. A communication unit 204, an output unit 205 for displaying the result of data calculation / processing on the display or the like for the change manager 30, and an input unit 206 for receiving keyboard input, mouse input, or the like from the change manager 30. However, the hardware configuration is mutually connected by the bus 207.

  For example, the storage unit 203 holds a configuration information input unit 2, a change scenario input unit 3, an influence location analysis unit 4, and an operation simulation unit 5 as programs, and the CPU 201 reads and executes these programs. By doing so, the necessary functions can be implemented.

  Hereinafter, functional units of the change management analysis apparatus 1 realized by a program will be described. The change management analyzer 1 reads the layout information of the devices constituting the entrance / exit management system 10 in a predetermined area from the entrance / exit management system 10 (or the storage unit 203 in which data necessary for the entrance / exit management system 10 has been stored). A configuration information input unit 2 is provided. The configuration information input unit 2 in this embodiment accesses the room entry / exit management system 10 via the network 41, reads the configuration information table 11, schedule table 12, and authentication information table 13, and reads the map via the Internet 40. The information table 24 is read, and the layout information is created by arranging the icons and the like of the devices for room entry / exit management on the map showing the room entry / exit management area based on the information.

  The configuration information input unit 2 accepts the addition of device or function information to the product information table 23 from another device that is communicably connected via the input unit 206 or the networks 40 and 41, and the product information. The table 23 may be updated.

  In addition, the change management analysis apparatus 1 displays the layout information on the output unit 205 and receives from the input unit 206 a change scenario including the change location and change contents of the configuration in the layout of the entrance / exit management system 10. An input unit 3 is provided.

  The change scenario input unit 3 displays a list of location information included in the layout information on the output unit 205 such that a pull-down menu or the like can be selected. The change scenario input unit 3 accepts selection of the change location from the location list, If the change scenario stored in 203 is displayed on the output unit 205 in a selectable manner such as a pull-down menu, and the change scenario is accepted from the change content list, the change scenario is accepted. Is preferred.

  Here, the change scenario input unit 3 of the present embodiment includes a change scenario table 21 that stores a list of the location information that accepts selection of the change location and a list of change content that accepts selection of the change content. It is held in the storage unit 203. In this case, the change scenario input unit 3 adds location information to the list of location information in the change scenario table 21 from the other device connected to be communicable through the input unit 206 or the networks 40 and 41, or the contents of the change. It is preferable that the change scenario table 21 is updated by accepting the change content addition to the list.

  Further, when the change scenario indicates addition or change of a device or function, the change management analysis device 1 stores the change content in a product information table 23 that stores function information of devices that can constitute the entrance / exit management system 10. Collate and identify candidate devices that have the function of satisfying the change request, and add candidate devices to the change location in the layout, or display replacement of existing devices and candidate devices at the change location When the designation information indicates deletion of a device or a function, the influence location analysis unit 4 is provided to delete the device at the change location in the layout and display it on the output unit 205 as a changed configuration plan.

  In addition, when the change scenario indicates addition or change of a device or a function, the influence location analysis unit 4 collates the change content with the product information table 23 and has a function that satisfies the request for the change content. A plurality of candidate devices, and display a change configuration proposal that satisfies the change scenario by adding candidate devices to the change location in the layout or displaying replacement of existing devices and candidate devices at the change location for each candidate device. A plurality may be generated and displayed on the output unit 205. For example, it is assumed that a person in charge of sales activities for the change of the entrance / exit management system 10 carries the change management analyzer 1 and makes a system proposal at the customer. In such a situation, generally speaking, it is more preferable to present a plurality of the modified configuration proposals and to give the customer a room for selection than to present only one modified configuration proposal.

  Further, the influence location analysis unit 4 reads out data of necessary costs for addition, change, or deletion from the product information table 23 for the device to be added, changed, or deleted indicated by each changed configuration plan, It is preferable that the estimated price is calculated by adding the necessary expenses for each modified configuration plan and is output while the corresponding modified configuration plan is displayed. For example, when a certain device group is additionally introduced, the estimated price is calculated by extracting the costs related to each device from the product information table 23 and adding them together. The same applies to other operations.

  In addition, the change management analysis apparatus 1 accepts the specification of operation conditions for the change configuration proposal by the input unit 206 and applies the operation conditions to the function information of the device in the product information table 23 under the operation conditions. An operation simulation unit 5 is provided for simulating the behavior when the device is operated and outputting the simulation result while the changed configuration plan is displayed. As an operation condition, for example, it can be assumed that 1000 employees enter / exit in one gate (= location condition) in one hour (= condition of operation content). Therefore, in this case, the operation simulation unit 5 uses the product information table for the functions provided in the entry / exit management device installed at “a certain gate”, for example, the processing time “1 second” required for one authentication. 23, information is extracted. Then, when trying to process “3000 people entering / leaving an hour”, it is calculated that “60 × 60/1” = 3600 people> 3000 people, and it can be determined that the operation conditions can be satisfied, "3000/1" = 3000 seconds = 50 minutes.

  In addition, the operation simulation unit 5 affects, affects, and affects the addition, replacement, or deletion of the device based on the change scenario, or the stop or replacement of the device under a predetermined operation condition determined by the simulation. It is preferable to highlight at least one piece of information of the influence contents while displaying the changed configuration plan. This is a process for making it easy to visually recognize the corresponding part as well as changing the display of the existing device to the display of a new device, for example, by replacing the device. For example, regarding the display of the device after the change, the line type may be made thicker than the other, the color or pattern may be changed, or the text or icon for notifying the change may be arranged.

  Further, the operation simulation unit 5 executes the simulation for each changed configuration plan, outputs a simulation result for each changed configuration plan while displaying the corresponding changed configuration plan, and displays the changed configuration plan that the operator has determined to be optimal. It is preferable that the designation is received by the input unit 206 and the corresponding changed configuration plan is displayed on the output unit 205 as the optimal plan.

  Further, the operation simulation unit 5 displays a list of location information included in the layout information in a selectable manner using a pull-down menu or the like. The operation simulation unit 5 accepts selection of a location among the operation conditions from the location list, and stores it in the storage unit 203 in advance. It is preferable to accept the specification of the operation condition by displaying a list of the operation contents that are held so that it can be selected from a pull-down menu or the like, and accepting selection of the operation contents from the operation conditions from the operation content list. It is.

  In addition, the operation simulation unit 5 holds, in the storage unit 203, an operation scenario table 22 that stores a list of the location information that accepts selection of a location among the operation conditions and a list of the operation contents. This is preferable. In this case, the operation simulation unit 5 adds the location information to the list of the location information in the operation scenario table 22 from the other unit connected to be able to communicate with the input unit 206 or the networks 40 and 41, or the operation content. It is preferable to accept the addition of the operation content to the list and execute the process of updating the operation scenario table 22.

The change scenario table 21 includes change pattern information 411 and change correspondence information 412 as one line, and has data of a table structure including a plurality of lines. The change pattern information 411 in the change scenario table 21 includes change place information (“place” in the drawing) and change content information.

  Examples of the change location information include “A building 1F in the XX district”, and examples of the change content information include “door and card reader addition”. As the change contents, for example, an addition of a door, a change of a device, cooperation with another system, an arbitrary request, and the like can be assumed. Further, the change correspondence information 412 is set as a result of specifying the candidate device having a function that the affected part analysis unit 4 collates the change content with the product information table 23 and satisfies the request for the change content. The

--- Processing flow example ---
The processing procedure of the change management analysis method according to the present embodiment will be described with reference to FIGS. 5 to 9 in consideration of the functions of the change management analysis apparatus 1 described above and the available tables. FIG. 5 is a flowchart showing the processing procedure of the change management analysis method of this embodiment. Here, for example, it is assumed that the change manager 30 activates the change management analysis apparatus 1 as an information processing apparatus and the change management analysis process is started.

  At this time, first, the configuration information input unit 2 accesses the entry / exit management system 10 via the network 41, reads the configuration information table 11, schedule table 12, and authentication information table 13, and reads the map via the Internet 40. The information table 24 is read (step 501).

  Further, the configuration information input unit 2 displays, on the map indicating the entry / exit management area (= map data acquired from the map information table 24) on the basis of the information read in step 501, an icon of an entry / exit management device. Etc. are arranged at a position (such as a coordinate value on the map) indicated by the installation location information 311 of the corresponding device, layout information is created, and displayed on the output unit 205 (step 502). Thereby, the manager 30 can check the layout of the entrance / exit management system 10 = the layout of the devices and edit the layout. In other words, the configuration information input unit 2 receives the layout editing work by the manager 30 through the layout information displayed on the output unit 205.

  FIG. 6A shows an example of a screen interface 600 in layout editing. The screen interface 600 includes a button group 601 for editing the corresponding element and an installation layout drawing area 602. In the example shown in FIG. 6A, on the floor having “compartment 1” and “compartment 2”, “door 1” is arranged at the entrance of “compartment 1” and “door 2” is arranged at the entrance of “compartment 2”. Has been. Furthermore, the “door 1” is provided with an electric lock “EK1”, which is used when a person enters the “compartment 1” and a card reader “CR1” used when the person enters the “compartment 1”. A card reader “CR2” is installed. “EK1”, “CR1”, and “CR2” are connected to “controller 1” by a serial cable. The “controller 1” is connected to the “management server 1” with a LAN cable.

  Note that the configuration information input unit 2 reads the installation device information 312 and displays it on the output unit 205 when the installation location information 311 in the configuration information table 11 is insufficient to create such a layout, and displays these installation devices. The installation location and connection method may be designated by the change manager 30 through the input unit 206.

  Subsequently, the change scenario input unit 3 receives, from the input unit 206, an input of the change scenario including the change location of the configuration and the change contents on the layout displayed on the output unit 205 as described above (step 503). . The change scenario input unit 3 adds location information to the list of location information in the change scenario table 21 from the other units connected to be able to communicate with the input unit 206 or the networks 40 and 41, or the contents of the change. The change scenario table 21 may be updated by accepting the addition of changes to the list. Such processing leads to an increase in user options.

  FIG. 6B shows an example of the screen interface 610 in the change scenario input in step 503. The screen interface 610 includes a button group 611 for scenario input and an installation layout designation area 612. In the example shown in FIG. 6B, it is assumed that “add door” is clicked from the button group 611 for scenario input. At this time, it is assumed that the change scenario input unit 3 displays a list of change locations by a pull-down menu or the like, and receives a selection from the manager 30 for the entrance / exit of “section 2”, for example. Receiving this, the change scenario input unit 3 reads and draws the icon data of “door 2” at the predetermined location. It is assumed that this “door 2” is clicked. In this case, the change scenario input unit 3 performs a drawing process of surrounding the “door 2” with a rectangle 613 in the designated area 612. If the rectangle 613 is clicked, the change scenario input unit 3 pops up a device change content list, for example, and “EK addition”, “CR addition” for entry, “CR addition” for exit. The designation of the change contents is accepted from the list.

  Subsequently, when the change scenario indicates addition or change of a device or a function, the influence point analysis unit 4 is applied with a function that matches the change content with the product information table 23 and satisfies the request for the change content. Possible product = candidate device is identified (step 504). Further, the influence location analysis unit 4 generates a changed configuration plan by adding a candidate device to the change location in the layout or displaying a replacement of the existing device and the candidate device at the change location, and outputs the change configuration plan 205. Displayed above (step 505). When the designation information indicates the deletion of the device or function, the affected part analysis unit 4 deletes the device at the changed place in the layout and displays it on the output unit 205 as a changed configuration plan.

  FIGS. 7C-1 and 7C-2 and FIG. 8C-3 show examples of the screen interfaces 700, 710, and 800 of the modified configuration plan. The screen interface 700 includes a tab list 701 indicating a list of changed configuration proposals, a layout drawing area 702 after the change, and a price estimation button 703. In the example shown in FIG. 7 (c-1), “EK 2”, “CR 3”, and “CR 4” are newly provided in “Door 2” and “Controller 2” that is serially connected to them is proposed as a modified configuration plan 1. The layout is such that the “controller 2” is newly connected to the existing “management server 1” via a LAN connection. In this example, since “EK2”, “CR3”, “CR4”, and “controller 2” to be newly established are affected parts, the display is highlighted such as a thick line. The same applies to other examples.

  In the example shown in FIG. 7C-2, the existing “controller 1” is newly changed to “controller 3”, and “door 2” is changed to “EK2” and “CR3” as proposed change configuration 2. And “CR4” are newly installed, they are serially connected to the newly installed “controller 3”, and the newly installed “controller 3” is connected to the existing “management server 1” via a LAN connection.

  Further, in the example shown in FIG. 8C-3, as the proposed modified configuration 3, the existing “controller 1” is newly changed to “controller 4”, and “EK2” and “CR3” are changed to “door 2”. And “CR4” are newly installed, they are serially connected to the newly installed “controller 4”, and in addition to the existing “management server 1”, the entrance / exit can be managed by a Web browser.

  In other words, in response to the addition of “EK”, “CR” for entering the room, and “CR” for leaving the room in the change scenario input in FIG. 6B, the influence point analyzing unit 4 adds such devices. At this time, the controller information required for operating the device is searched in the product information table 23 to obtain “controller 2” and “controller 3”. This shows a situation where three types of “controller 4” have been identified. Since “controller 3” and “controller 4” have twice the number of devices that can be controlled as “controller 1” and “controller 2”, the existing controller can be replaced. FIG. ), And the layout shown in FIG.

  For example, it is assumed that the person in charge of sales activities for the change of the entrance / exit management system 10 = the manager 30 who carries the change management analyzer 1 and makes a system proposal at the customer. In such a situation, generally speaking, as shown in FIGS. 7 (c-1), (c-2), and FIG. 8 (c-3), rather than presenting only one modified configuration proposal. Presenting multiple items and giving room for selection on the customer side has the advantage that it is easier for the customer to make a selection, and that the sales representative can propose a system using comparative theory, so it is easier to make a contract.

  Note that when the price estimation button 703 is pressed on the changed configuration plan screen interface shown in FIG. 7C-1 or the like, the influence location analysis unit 4 changes to the layout of the corresponding changed configuration plan. The estimated amount will be calculated and displayed. In this process, the influence point analysis unit 4 reads out data of necessary costs for addition, change, or deletion from the product information table 23 for the device to be added, changed, or deleted indicated by the corresponding changed configuration proposal, The estimated price is calculated by adding the necessary costs for the proposed change composition. It is preferable that the calculated estimated amount information is output while the corresponding changed configuration plan is displayed.

  Subsequently, the operation simulation unit 5 receives an operation condition designation for the changed configuration proposal at the input unit 206 and applies the operation condition to the function information of the device in the product information table 23 under the operation condition. The behavior when the device is operated is simulated, and the simulation result is output while the changed configuration plan is being displayed (step 506).

  As the operation condition, for example, “passage rush” at a certain door (= location condition) = 1000 employees enter / exit in one hour (= condition of operation contents) can be assumed. Therefore, in this case, for example, the operation simulation unit 5 has the product information about the function provided in, for example, the card reader “CR4” installed in the “door 2”, for example, the processing time “1 second” required for one authentication. Information is extracted from the table 23. Then, when trying to process “3000 people entering / leaving an hour”, it is calculated that “60 × 60/1” = 3600 people> 3000 people, and it can be determined that the operation conditions can be satisfied, "3000/1" = 3000 seconds = 50 minutes. These results are output during the display of the corresponding modified configuration proposal.

  FIG. 8D shows an example of the screen interface 810 during operation simulation. The screen interface 810 includes a button group 811 used for inputting operation contents in the operation conditions, and a drawing area 812 for inputting a place condition in the operation conditions and confirming the result. In the example shown in FIG. 8D, it is assumed that “log storage period” is clicked from the button group 811 as the operation content, and “door 1” is designated in the drawing area 812. Receiving this, the operation simulation unit 5 receives the specification of the length of the log storage period and the entry / exit frequency as operation simulation information corresponding to the operation content “log storage period”. Also, the operation simulation unit 5 wants to store “entrance / exit log for one year (= the length of the storage period) as operation simulation information in response to the display of“ door 1 ”. In the case of leaving frequency), information such as “how much GB is necessary for storage?” Naturally, the operation simulation unit 5 executes the simulation of the step 506 according to such operation conditions.

  Similarly, it is assumed that “passage rush” is clicked from the button group 811 as the operation content, and “door 2” is designated in the drawing area 812. Receiving this, the operation simulation unit 5 receives, as the operation simulation information corresponding to the operation content “traffic rush”, the input unit 206 accepts specification of the time zone during which the rush occurs and the entrance / exit frequency. In addition, the operation simulation unit 5 responds to the display of “door 2” as operation simulation information “when 1000 employees pass in the morning (= rush hour) (= entrance / exit frequency)”. , How long is the waiting time? Naturally, the operation simulation unit 5 executes the simulation of the step 506 according to such operation conditions.

  The change manager 30 browses the result of operation simulation under a predetermined operation condition in the changed configuration plan, determines whether there is a problem related to the changed configuration plan, and inputs the determination result through the input unit 206. The operation simulation unit 5 receives the determination result and determines the content (step 507). If it is determined that there is no problem (step 507: no problem), the operation simulation unit 5 uses the changed configuration plan as an optimal plan, an electronic file, a paper document, and other means that can be stored. (Step 508). On the other hand, if the result of the determination is that there is a problem (step 507: there is a problem), the operation simulation unit 5 returns the processing to step 505 again, and performs simulation under the operation conditions for other modified configuration proposals. And check again for problems.

  In addition, the operation simulation unit 5 affects, affects, and affects the addition, replacement, or deletion of the device based on the change scenario, or the stop or replacement of the device under a predetermined operation condition determined by the simulation. It is preferable to highlight at least one piece of information of the influence contents while displaying the changed configuration plan. This is a process for making it easy to visually recognize the corresponding part as well as changing the display of the existing device to the display of a new device, for example, by replacing the device. For example, regarding the display of the device after the change, the line type may be made thicker than the other, the color or pattern may be changed, or the text or icon for notifying the change may be arranged.

  In addition, the operation simulation unit 5 holds, in the storage unit 203, an operation scenario table 22 that stores a list of the location information that accepts selection of a location among the operation conditions and a list of the operation contents. This is preferable. In this case, the operation simulation unit 5 adds the location information to the list of the location information in the operation scenario table 22 from the other unit connected to be able to communicate with the input unit 206 or the networks 40 and 41, or the operation content. It is preferable to accept the addition of the operation content to the list and execute the process of updating the operation scenario table 22.
