Summary of the Invention

Problems to be Solved by the Invention

[0004] In some cases, the administrator who manages the building cannot appropriately handle the above alarms. For example, there are cases where the administrator leaves the alarms unconfirmed. Or, although it could be handled by the administrator alone, there are cases where an unnecessary report is made to a maintenance company that maintains the above system, assuming there is a system malfunction.

[0005] This is because the above system simply issues alarms, and there is a problem in that it is difficult for the administrator to know how to handle the alarms.

[0006] The present disclosure has been made to solve the above problems, and an object thereof is to provide an alarm analysis system and a control method thereof that make it easy for an administrator to know how to handle an alarm when an alarm related to a facility in a building is issued.

The alarm analysis system comprises a storage device that stores a database containing the history of alarm occurrences, the causes of alarm occurrences, and countermeasures for those alarms; a processing device that uses the content of the generated alarm and the database to output the causes of the generated alarm and countermeasures as analysis results; and a display device that displays the analysis results. The display device displays a floor plan of the building along with information about the equipment. The display device displays the analysis results of the generated alarms at the locations of the equipment on the floor plan.

[0008] The control method relating to this disclosure is a control method for an alarm analysis system that analyzes alarms related to equipment installed in a building. The alarm analysis system comprises a storage device that stores a database including alarm occurrence history, alarm causes, and countermeasures for the alarms, a processing device, and a display device. The control method comprises the steps of the processing device outputting the cause and countermeasures for the generated alarm as analysis results using the content of the generated alarm and the database, and the display device displaying the analysis results. The display step includes the steps of the display device displaying a floor plan of the building along with equipment information, and the display device displaying the analysis results of the generated alarms at the location of the equipment on the floor plan. [Effects of the Invention]

[0009] This disclosure makes it clear how administrators should respond when an alarm related to building equipment is triggered. [Brief explanation of the drawing]

[Figure 8] This figure shows an example of a database of countermeasures. [Figure 9] This is a flowchart of the processes performed by the alarm analysis system. [Modes for carrying out the invention]

[0011] The embodiments will be described below with reference to the drawings. In the following description, identical parts are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed descriptions of them will not be repeated.

[0012] Figure 1 shows a schematic configuration of the alarm analysis system 100. The alarm analysis system 100 is a system that analyzes alarms related to equipment installed in a building and also monitors and manages the equipment installed in the building. The alarm analysis system 100 is installed inside the building. In this embodiment, the building is an office building. However, it is not limited to this, and the building may be a commercial building, factory, hospital, school, etc.

[0013] The building is divided into several sections, including living quarters, and each section can be accessed by opening either an electric lock door 200 or an automatic door 300. Employees working in the building carry ID cards.

[0014] When an employee holds an ID card (IC card) near the contactless card reader 202 of the electric lock door 200, the electric lock 201 (Figure 2) is unlocked. Thereby, the employee can open the electric lock door 200. The entry / exit management system 90 acquires the information of the IC card from the card reader 202 and controls the unlocking of the electric lock 201 when the owner of the IC card has the right to enter the room.

[0015] Above the automatic door 300 (under the ceiling 61), a door sensor 302 is provided. When the door sensor 302 detects a person, the automatic door 300 opens. Note that a card reader 202 may also be provided on the automatic door 300 so that the automatic door 300 can be opened by authenticating the IC card.

[0016] The alarm analysis system 100 includes a server device 10, a terminal 80, an air-conditioning management system 70, an entry / exit management system 90, a plurality of electric lock doors 200, and a plurality of automatic doors 300.

[0017] The air-conditioning management system 70 is a system that manages a plurality of air-conditioning devices (not shown) installed in the building. The entry / exit management system 90 is connected to a plurality of electric lock doors 200 and a plurality of automatic doors 300, and is a system that manages the entry and exit to each section through these doors. The entry / exit management system 90 controls the opening and closing of the electric lock doors 200 and the automatic doors 300.

[0018] The server device 10 manages facilities installed in the building, such as the air-conditioning management system 70 and the entry / exit management system 90. In addition, the server device 10 also manages a monitoring camera system that monitors the building.

[0019] The terminal 80 is a device used by the administrator (user) of the building. The terminal 80 can be communicatively connected to the server device 10. The terminal 80 can acquire information from the server device 10 and display it. For example, the terminal 80 displays information about the facilities in the building that the server device 10 has acquired from the air-conditioning management system 70 and the entry / exit management system 90, etc.

[0020] Figure 2 is a diagram showing the hardware configuration of the alarm analysis system 100. The server device 10 includes a processor 11, a memory 12, a storage device 14, and a communication IF (Interface) 15. These exchange various data through a communication path 16.

[0021] The processor 11 is, for example, a CPU (Central Processing Unit). The memory 12 includes a ROM (Read Only Memory) and a RAM (Random Access Memory). The storage device 14 is, for example, a HDD (Hard Disk Drive) or a SSD (Solid State Drive). The processor 11 expands and executes a program stored in the storage device 14 or the ROM in the RAM. This program describes the processes executed by the server device 10.

[0022] The communication IF 15 is an input / output device for exchanging data with the air-conditioning management system 70, the entry / exit management system 90, and the terminal 80. The storage device 14 is a storage for storing various information. In the storage device 14, there are stored a generation history DB 501 for recording the generation history of alarms, a generation cause DB 502 for recording the generation causes of alarms, a countermeasure method DB 503 for recording countermeasure methods for alarms, etc., which will be described later.

[0023] Similar to the server device 10, the entry / exit management system 90 is configured to include a processor 91, a memory 92, a storage device 94, and a communication IF 95. The entry / exit management system 90 can communicate with the server device 10, the electric lock door 200, and the automatic door 300 by resolving the communication IF 95.

[0024] The electric lock door 200 includes an electric lock 201 and a card reader 202. The automatic door 300 includes a door device 301 and a door sensor 302 that control the opening and closing of the door. The air conditioning management system 70 similarly includes a processor, memory, storage device and communication interface (not shown). The air conditioning management system 70 is connected to several air conditioning units (not shown).

[0025] The terminal 80 comprises a control unit 81, an input unit 82, and a display unit 83. The control unit 81 is similarly configured to include a CPU, RAM, ROM, storage device, and communication interface. The display unit 83 displays various types of information. The display unit 83 can be, for example, a liquid crystal display, a display, or a touch panel. The input unit 82 receives input from the user to the terminal 80. The input unit 82 can be, for example, a keyboard, a mouse, or a touch panel.

[0026] Figure 3 shows an example of a display on the display unit 82. Figure 3 shows the display screen 400 displayed on the display unit 82 of the terminal 80. The terminal 80 acquires building information from the server device 10 and displays various information such as alarms, along with floor plans for each floor of the building, on the display screen 400.

[0027] The display screen 400 shows four sections (living spaces, etc.) labeled A to D within the floor, with a door at the entrance to each section. Section A has an electric lock door 200 with device ID "X001" at its entrance. The screen displays "X001" indicating the device ID, "E" indicating that it is an electric lock door 200, and a round icon indicating that the electric lock door 200 is unlocked.

[0028] An automatic door 300 with device ID "X002" is installed at the entrance to section B. The screen displays "X002" indicating the device ID, "A" indicating that it is automatic door 300, and a round icon indicating that automatic door 300 is locked (closed).

[0029] At the entrance to section C, there is an electric lock door 200 with device ID "X003". On the screen, "X003" indicating the device ID, "E" indicating that it is an electric lock door 200, and a round icon indicating that the electric lock door 200 is unlocked are displayed.

[0030] At the entrance to section D, there is an electric lock door 200 with device ID "X004". On the screen, "X004" indicating the device ID, "E" indicating that it is an electric lock door 200, and a round icon indicating that the electric lock door 200 is generating an alarm and that the alarm is occurring frequently.

[0031] The following describes the displays that appear when an alarm occurs. Alarms related to doors include an electric lock malfunction related to the operation of the electric lock installed on the door (first alarm) and a prolonged open state due to the door being open for a period of time exceeding the set time of the time-based open detection timer (timer time) (second alarm).

[0032] Figure 4 shows an example of the display on the display unit 82 when an electric lock malfunction occurs. In this example, an alarm (electric lock malfunction) has occurred on the electric lock door 200 with device ID "X001" located at the entrance of section A. The causes of the electric lock malfunction include improper door installation and malfunction due to an object being caught in the door.

[0033] When an alarm occurs, the server device 10 analyzes the cause and countermeasures for the alarm and displays them on a floor plan. When a user (administrator) using terminal 80 moves the mouse cursor over the location of the electric lock door 200 displayed on the screen, a pop-up message is displayed. The pop-up message is determined based on the occurrence history DB 501, the cause DB 502, and the countermeasure method DB 503, which will be described later.

[0034] The pop-up message displays something like, "The electric lock has malfunctioned 10 times in the last hour. Possible causes include: 1. Poor door alignment. 2. An object is stuck near the deadbolt." In this way, the cause is displayed when it is determined that electric lock malfunctions are occurring frequently (for example, if they occur more than the specified number of times in the last hour). Note that the cause may be displayed regardless of the frequency of occurrence.

[0035] The message indicates that the most common cause of the alarm is "a door not opening properly" (Cause 1), and the second most common cause is "something stuck near the deadbolt" (Cause 2). Although not illustrated, the third most common cause (Cause 3) and the fourth most common cause (Cause 4) are also shown. Furthermore, a pie chart showing the percentage of causes 1 to 4 is displayed. This makes it easy to intuitively understand the cause of the alarm.

[0036] In this example, the cause and the solution are the same. That is, the solution for cause 1 is to check the door's alignment and correct it. The solution for cause 2 is to check if anything is stuck near the deadbolt and remove it if any is found. In cases like this, where the cause and solution are two sides of the same coin, only the cause may be displayed.

[0037] In addition, for example, the system may be designed to show the cause of the alarm and countermeasures for cases such as when the ID card is touched to the card reader 202 but the card reader 202 does not react, or when the card reader 202 reacts but the door does not open.

[0038] Figure 5 shows an example of the display on the display unit 82 during a prolonged period of openness. The countermeasure against prolonged openness includes changing the setting time (timer time) of the prolonged openness detection timer to a new setting value (change time) that is greater than the current setting value. When the display unit 83 of the terminal 80 displays the analysis results of prolonged openness, it displays the screen for changing the setting time (timer time) of the time openness detection timer.

[0039] In this example, an alarm has been triggered on automatic door 300 with device ID "X002" located at the entrance to section B. When a user using terminal 80 places the mouse cursor over the location of automatic door 300 displayed on the screen, a pop-up message is displayed. The pop-up message is determined based on the incident history DB501, incident cause DB502, and countermeasure method DB503, which will be described later.

[0040] The pop-up message displays, "Long-duration openings have occurred 15 times in the last hour. You can reduce the frequency of alarms by changing the long-duration opening detection timer." A "Settings screen" button is also displayed. In this way, the system displays countermeasures when it determines that long-duration openings are occurring frequently (for example, if they occur more than a specified number of times in the last hour). Alternatively, the system may display countermeasures regardless of the frequency of long-duration openings.

[0041] The reason for frequent prolonged door openings is the high volume of people entering and exiting the area. Automatic door 300 detects "prolonged opening" and issues an alarm if the door remains open for longer than the set "timer period." The alarm is deactivated when the door closes. High and continuous foot traffic makes prolonged openings more likely. In cases of prolonged openings, a pop-up message displays countermeasures.

[0042] When the user clicks the "Settings" button, a screen appears where the timer duration for the long-term open detection timer can be changed. The current timer duration is "30 seconds," and it is indicated that it can be changed to "40 seconds" (change duration). Clicking the "YES" button changes the timer duration from "30 seconds" to "40 seconds." Clicking the "NO" button exits the change screen without changing the timer duration.

[0043] The server device 10 determines the change time for the timer. For example, the change time may be determined based on the average actual door opening time (for example, if the average is 30 to 40 seconds, the "change time" may be set to "40 seconds", and if the average is 40 to 50 seconds, the "change time" may be set to "50 seconds"). In this example, "40 seconds" is displayed as the change time, but this may be changeable by user (administrator) input.

[0044] Alternatively, the "change time" for the timer may be determined according to the use, condition, and purpose of the building or section. For example, the "change time" for the timer may be set longer (set to "50 seconds") for entry into and exit from sections with a high volume of cargo, while the "change time" may be set shorter (set to "40 seconds") for entry into buildings with high security, such as data centers, or into sections with high security.

[0045] As a variation of this embodiment, the flow of people passing through the automatic door 300 may be measured (the number of people passing through the automatic door 300 is measured by a sensor) over a predetermined period of time (for example, one month), and the aggregated results may be displayed simultaneously. For example, the total number of people passing through the automatic door 300 (flow of people) may be aggregated on a daily basis, and the average value for each day of the week may be displayed in a bar graph. In the example shown in the figure, it can be seen that the flow of people is higher from Monday to Friday than on Saturdays and Sundays, and that the flow of people is highest on Mondays.

[0046] Furthermore, the total number of people passing through these 300 automatic doors (pedestrian flow) is tallied every hour, and the average value for each time period is displayed as a bar graph. In the example shown in the figure, it can be seen that the pedestrian flow is highest in the 9 AM hour. For example, if there is a lot of cargo being delivered in the 9 AM hour, the alarm will be triggered frequently.

[0047] In this modified example, the server device 10 determines a value greater than the current timer setting as the setting value (change time) during periods of high foot traffic. For example, if the average foot traffic for a given time period exceeds the first person, the change time is set to a value 10 seconds greater than the current setting value. If it exceeds the second person, which is greater than the first person, the change time is set to a value 20 seconds greater than the current setting value. In this example, since the foot traffic from 9:00 to 10:00 exceeds the second person, the change time for 9:00 to 10:00 is set to "50 seconds," which is 20 seconds greater than the current setting value of "30 seconds."

[0048] When the user clicks the "Settings" button, a screen appears where the timer duration for the long-loose detection timer can be changed. The current timer duration is "30 seconds," and it is indicated that this can only be changed to "50 seconds" (change duration) between 9:00 and 10:00. Clicking the "YES" button changes the timer duration from "30 seconds" to "50 seconds" between 9:00 and 10:00, while the timer duration for other time periods remains at "30 seconds." Clicking the "NO" button exits the change screen without changing the timer duration.

[0049] In this way, the server device 10 determines a new setting value (change time) based on the history of door open times when prolonged opening occurs. The display unit 83 of the terminal 80 displays a change screen for changing the setting time (timer time) of the time-open detection timer to the new setting value. The server device 10 also aggregates the flow of people passing through the door for each time period. The display unit 83 of the terminal 80 applies the current setting value as the setting time (timer time) of the time-open detection timer during time periods when the flow of people is below the standard value, and displays a change screen for applying a new setting value (change time) as the setting time (timer time) during time periods when the flow of people exceeds the standard value.

[0050] The following describes the various databases stored in the memory 12 of the server device 10. Figure 6 shows an example of the occurrence history DB 501. The occurrence history DB 501 records the history of alarms.

[0051] The incident history DB501 shows that at time T1, an alarm "Electric Lock Malfunction" occurred for electric lock door 200 (Type: Electric Lock) with device ID "X001". This alarm was resolved (ended) at time T2.

[0052] The incident history DB501 shows that at time T3, an alarm for "long-term open" occurred for automatic door 300 (type: automatic door) with device ID "X002". This alarm was reset at time T4. This means that the timer setting value (30 seconds) was reached at time T3, and the alarm continued to be active until time T4. In this case, the door was open for 30 seconds + (time T4 - time T3).

[0053] The incident history DB501 shows that at time T5, an alarm for automatic door 300 with device ID "X002" was triggered for "prolonged open status". This alarm was resolved at time T6. This example shows that the "prolonged open status" alarm for automatic door 300 with device ID "X002" occurred repeatedly.

[0054] The average door opening time, as explained in Figure 5, is calculated based on data obtained from the incident history database 501. The pedestrian flow graph shown in Figure 5 is also created based on data obtained from the incident history database 501.

[0055] Figure 7 shows an example of the Cause Database (DB502). The Cause Database (DB502) records the cause of each alarm that occurred and its ranking (No.). The Cause Database (DB502) records that the most common cause (No. 1) of the "electric lock malfunction" alarm for the electric lock door 200 is "poor door alignment" (occurrence count: "N1"), followed by the second most common cause (No. 2) being "object stuck near the deadbolt" (occurrence count: "N2"). N1 > N2.

[0056] In the example shown in Figure 4, when displaying a pop-up message regarding an electric lock malfunction, information is retrieved and displayed from the cause database DB502. In the example in Figure 4, the causes are listed and displayed in descending order of priority. Alternatively, only causes with an occurrence frequency above a predetermined value may be displayed.

[0057] The cause of the problem DB502 may be configured so that data previously distributed by the maintenance company is stored in the storage device 14. In this case, the cause of the problem DB502 may be historical data of similar items or equipment of the same model accumulated by the maintenance company.

[0058] Alternatively, the building administrator (user) may configure the terminal 80 to update the cause database 502. For example, if an electric lock malfunction occurs and the problem is addressed, the cause is selected and recorded from the terminal 80. For example, in the case of an electric lock malfunction, options such as "faulty door installation" or "object stuck near the deadbolt" recorded in the cause database 502 are displayed on the terminal 80. When the administrator selects an option and sets it, the "number of occurrences" for the selected option in the cause database 502 is updated by incrementing by one. If no option exists, the administrator can enter one. In this case, a new "cause" item is added to the cause database 502. In this way, the cause database 502 is updated for each building.

[0059] Furthermore, the cause database 502 may be stored on a cloud server managed by the maintenance company. The servers 10 in each building may be configured to access the cause database 502 on the cloud server. In this case, the cause database 502 may be managed on a per-device-model basis, on a per-building basis, or on a per-area basis within a building.

[0060] The pie chart shown in Figure 4 is generated based on the cause database DB502. In this case, the number of occurrences for cause 1 is "N1", the number of occurrences for cause 2 is "N2", the number of occurrences for cause 3 is "N3", and the number of occurrences for cause 4 is "N4" (N1>N2>N3>N4). The pie chart shown in Figure 4 is a graph of the ratios of N1, N2, N3, and N4.

[0061] Figure 8 shows an example of countermeasure DB503. Countermeasure DB503 records countermeasures for alarms that occur. Countermeasure DB503 records the countermeasure for the alarm "long-term open" of the automatic door 300: "By changing the long-term open detection timer, the frequency of alarm occurrences can be reduced."

[0062] In the example in Figure 5, when displaying a pop-up message for a prolonged open state, information is retrieved and displayed from the countermeasure DB503. If there are multiple countermeasures, the system should be configured to record the "countermeasure" along with its "rank" and "number of times," similar to the cause DB502.

[0063] The countermeasure DB503 may be configured so that data distributed in advance by the maintenance company is stored in the storage device 14. In this case, the countermeasure DB503 may be historical data of similar properties or equipment of the same model accumulated by the maintenance company. Alternatively, the building administrator (user) may be configured to update the countermeasure DB503 using the terminal 80. The update method is the same as the update method for the cause DB502.

[0064] The following explanation will use a flowchart. Figure 9 is a flowchart of the processes performed by the alarm analysis system 100. Hereafter, "step" will also be simply referred to as "S".

[0065] The processes performed by the alarm analysis system 100 include server-side processes performed by the server device 10, terminal-side processes performed by the terminal 80, and processes performed by the access control system 90. These processes only need to be started periodically (for example, every 100 msec).

[0066] The server device 10 uses the content of the generated alarm and the database (incident history DB501, cause DB502, countermeasures DB503) to output the cause of the generated alarm and countermeasures as analysis results. The display unit 83 of the terminal 80 displays the floor plan of the building along with the equipment information. The display unit 83 displays the analysis results of the generated alarm at the location of the equipment on the floor plan. The display unit 83 displays the analysis results when the mouse cursor is moved to the location of the equipment on the floor plan.

[0067] As explained using Figure 7, suppose the administrator sets the information about the cause of the alarm from terminal 80. When the server device processing starts, the server device 10 updates the cause DB 502 based on the information about the cause entered by the administrator (S100).

[0068] When the access control system 90 receives alarm information from an electric lock door 200 or an automatic door 300, it transmits the alarm information to the server device 10. The server device 10 updates the occurrence history DB 501 based on the received alarm information (S101, see Figure 6). Furthermore, the server device 10 compiles the alarm occurrence status based on the received alarm information (S101). This generates information such as the frequency of electric lock malfunctions and pie charts, as shown in Figure 4.

[0069] If the server device 10 detects an alarm exceeding a certain threshold (YES in S102), it proceeds to S103. On the other hand, if the server device 10 does not detect an alarm exceeding a certain threshold (NO in S102), it terminates this process. If an alarm exceeding a certain threshold occurs, for example, in the example explained using Figure 4, it means that "electric lock malfunctions have occurred more than the specified number of times in the last hour." In the example explained using Figure 5, it means that "long-term open locks have occurred more than the specified number of times in the last hour." Note that the system may be configured to execute the processes from S103 onwards each time an alarm occurs.

[0070] The server device 10 obtains information from the cause DB 502 and the countermeasure DB 503, and generates the cause of the alarm and the countermeasure (S103). This generates the information for the pop-up message explained using Figures 4 and 5.

[0071] The server device 10 aggregates the pedestrian flow information (S104). This generates the pedestrian flow graph information explained using Figure 5. The server device 10 calculates the timer change time (S105). This determines the "change time" of the long-time open detection timer explained using Figure 5.

[0072] The server device 10 transmits display information to the terminal 80 (S106). Display information is information to be displayed on the display screen 400 of the terminal 80. This is information such as the pop-up message explained using Figures 4 and 5, and is information generated by the processing in S101 to S105.

[0073] Terminal 80 updates the display on the display screen 400 based on the display information received from the server device 10 (S201). This updates the content to be displayed in the pop-up messages, etc., as shown in Figures 4 and 5.

[0074] If terminal 80 detects a change in the timer time (YES in S202), it proceeds to S203. On the other hand, if terminal 80 detects no change in the timer time (NO in S202), it terminates this process. A change in the timer time means that the "YES" button was clicked on the timer time change screen in Figure 5. When the administrator moves the mouse cursor over the location of the equipment (door) displayed on the screen, a pop-up message with updated content is displayed.

[0075] Terminal 80 transmits the changed timer time (changed time) to the server device 10 (S202). This transmits the "changed time" information shown in Figure 5 to the server device 10. The server device 10 transmits a timer time change command based on the changed time received from terminal 80 to the access control system 90. The access control system 90 commands the electric lock door 200 or automatic door 300 to change the timer time to the received changed time.

[0076] As described above, the alarm analysis system 100 is a system that analyzes alarms related to equipment installed in a building. The alarm analysis system 100 includes a storage device 14 that stores a database (incident history DB501, incident cause DB502, countermeasure DB503) containing the history of alarm occurrences, the causes of alarm occurrences, and countermeasures for the alarms; a processor 11 that uses the content of the generated alarm and the database to output the cause of the generated alarm and the countermeasures as analysis results; and a display unit 83 that displays the analysis results. The display unit 83 displays a floor plan of the building along with information about the equipment. The display unit 83 displays the analysis results of the generated alarms at the location of the equipment on the floor plan.

[0077] In this way, when an alarm occurs, the display unit 83 shows the cause of the alarm and the countermeasures to be taken at the location of the equipment on the floor plan, allowing the building manager to deal with the alarm appropriately. This reduces the frequency of subsequent alarms and makes the system easier to use. It also reduces unnecessary reports and communications to the maintenance company. In this way, it is easy for the manager to understand how to deal with an alarm when one is issued regarding the building's equipment.

[0078] A mouse (input unit 82) is used as an input device for the display unit 83. The display unit 83 displays the analysis results when the mouse cursor is positioned over the location of the equipment on the floor plan. This allows for quick confirmation of countermeasures against alarms when necessary.

[0079] The equipment includes doors (200 electric lock doors, 300 automatic doors). Alarms related to the doors include electric lock malfunctions (first alarm) related to the operation of the electric lock installed on the door, and prolonged opening due to the door being left open for longer than the set time (second alarm). Causes of electric lock malfunctions include poor door installation and objects being caught in the door. Countermeasures for prolonged opening include changing the set time to a new set value that is greater than the current set value. This makes it easy for administrators to understand how to respond when an alarm is issued due to an electric lock malfunction or prolonged opening of a door.

[0080] The display unit 83 displays a screen for changing the set time when displaying the analysis results of prolonged opening. This allows for a quick reduction in the frequency of alarms caused by prolonged opening if they occur frequently.

[0081] The processor 11 determines a new setting value based on the history of door open times when prolonged opening occurs. The display unit 83 displays a change screen for changing the setting time to the new setting value. This allows for the setting of an appropriate new setting value according to the actual door open time when alarms due to prolonged opening occur frequently. This effectively reduces the frequency of alarms due to prolonged opening.

[0082] The processor 11 aggregates the flow of people passing through the door for each time period based on the history of how long the door was open when it was left open for an extended period. The display unit 83 applies the current setting value as the set time during time periods when the flow of people is below the standard value, and displays a change screen to apply a new setting value as the set time during time periods when the flow of people exceeds the standard value. This allows the set time to be extended only during time periods with high flow of people if alarms due to prolonged door opening occur frequently during those times.

[0083] The embodiments disclosed herein are illustrative and not limited to those described above. The scope of the present invention is defined by the claims, and all modifications within the meaning and scope equivalent to the claims are intended. [Explanation of symbols]
