Description

  The present invention relates to an information providing apparatus, an information providing system, and an information providing program, and more particularly to providing information related to movement of a user's location where a location is determined in a room by installing a seat (desk).

  Conventionally, a card reader is installed at the entrance and exit of the room where the workplace is located, and when the employee enters the room, the card reader can read the identification card carried by the card reader so that the location of each employee can be detected. Many companies have introduced management systems. In recent years, a system that effectively uses this room entrance / exit management system has been proposed. For example, if the positional relationship between the employee's seat position and lighting in a room with a workplace is stored in a database in advance, and the employee causes the card reader to read the identification card, only the lighting corresponding to the employee's seat position is provided. There has been proposed a system in which an entrance / exit management system and a lighting system are interlocked to turn on or automatically adjust the illuminance.

  Patent Documents 1 and 2 propose a system that turns on illumination or registers an elevator car according to the current location of a resident moving in a building.

The room 2 to which the present embodiment is applied is assumed to be one room in a building where employees work. In the description of the drawings, when a configuration with a subscript such as the illumination 8a is described generically, a subscript such as the illumination 8 is used. The room 2 shown in FIG. 1 is provided with three entrances, and a door 4 having an electric lock 3 and a card reader (CR) 5 as a reading means are installed at each entrance. The electric lock 3 is normally locked, and the ID controller 6 stores personal information stored in the user identification information obtained by the user holding an identification card such as an employee ID card carried on the card reader 5. If the authentication is successful, the electric lock 3 is unlocked.

  In the room 2, desks 7 used by each employee are arranged. That is, the location of each employee in the room 2 is determined by the arrangement of the desk 7. In the present embodiment, the desk 7 and the seat are used as synonymous words because they specify the location of each employee in the room 2. A lighting 8 is attached to the ceiling of the room 2. In FIG. 1, the attachment position of the illumination 8 is indicated by a wavy line. As illustrated in FIG. 1, the lighting 8 is distributed and arranged at eight locations above the desk 7 in the present embodiment. A switch panel including one or a plurality of switches (SW) 9 for turning on and off the respective lights 8 is provided on the wall where the room 2 enters from the entrance / exit. Although all the switches 9 included in the switch panel may be configured in the same manner, in the present embodiment, it is assumed that only the switch 9 corresponding to the illumination 8 close to each door 4 is included. For example, the switch panel corresponding to the door A in FIG. 1 includes switches 9 for the lights 8a, 8b, 8c, and 8d corresponding to the island 10a and the island 10b of the desk 7, respectively. The switch panel corresponding to the door B includes the switches 9 for the lights 8c, 8d, 8e, and 8f corresponding to the island 10b and the island 10c of the desk 7, respectively.

It transmits to the control system 20. In the traffic history information, date information specifying the date and time when the card reader 5 read the identification card, user identification information of the user specified from the identification card read by the card reader 5, and the entrance and exit where the user entered the room are specified. As information, door identification information for identifying a door installed at the entrance is included. The lighting control system 20 detects a switch operation by the user via the controller 12 and performs lighting control such as lighting and extinguishing of the corresponding lighting 8 and dimming. The administrator terminal 13 is a terminal device used by the administrator of this system. The entrance / exit management system 11, the lighting control system 20, and the manager terminal 13 exchange information via a network 14 such as a LAN.

An input / output controller 29 for connecting each display 28 and a network controller 30 provided as a communication means are connected to an internal bus 31.

  Although there may be a difference in performance, since the entrance / exit management system 11 and the administrator terminal 13 are also computers, the hardware configuration can be illustrated in the same manner as in FIG. Moreover, although the entrance / exit management system 11 and the lighting control system 20 are illustrated as being realized by one computer in FIG. 2, they may be realized by a plurality of computers.

  FIG. 4 is a block configuration diagram of the illumination control system 20 in the present embodiment. The illumination control system 20 in the present embodiment includes an illumination control system function processing unit 32, an equipment position information acquisition unit 33, a traffic history information acquisition unit 34, a learning unit 35, a change detection unit 36, a notification unit 37, and a learning information storage unit. 38. The illumination control system function processing unit 32 is a means for realizing a processing function of a conventional illumination control system. The equipment position information acquisition unit 33 acquires equipment position information sent when the lighting control system function processing unit 32 detects a switch operation by the user. The traffic history information acquisition unit 34 acquires the traffic history information generated when the card reader 5 reads the identification card carried by the user who enters the room from the entrance. The learning unit 35 includes the lighting 8 specified from the equipment position information acquired when the operation of the switch 9 is detected, the user specified from the traffic history information acquired immediately before the operation of the switch 9 is detected, and From the door 4, the user-door relevance degree representing the strength of the relation between the user and the door 4, the user-lighting relevance degree representing the strength of the relation between the user and the light 8, and the combination of the door 4 and the light 8. The door-lighting relevance degree that represents the strength of the association is calculated. The change detection unit 36 detects a change in related strength relationship for each degree of association. The notification unit 37 notifies the system administrator by transmitting to the administrator terminal 13 information indicating that a change in the related strength relationship has been detected at each relevance level by the change detection unit 36. The learning information storage unit 38 stores the result of learning by the learning unit 35.

  Each component 32-37 in the illumination control system 20 is implement | achieved by cooperation operation | movement with the program which operate | moves by the computer which forms the illumination control system 20, and CPU21 mounted in the computer. Further, the learning information storage unit 38 is realized by the HDD 24 mounted in the lighting control system 20. Alternatively, the learning information storage unit 38 may be configured by an external storage device, and necessary information may be acquired from the external learning information storage unit 38 via the network 14 when necessary.

  Further, the program used in this embodiment can be provided not only by communication means but also by storing it in a computer-readable recording medium such as a CD-ROM or DVD-ROM. The program provided from the communication means or the recording medium is installed in the computer, and various processes are realized by the CPU of the computer sequentially executing the installation program.

  Next, the operation in this embodiment will be described. The entrance / exit management system 11 and the lighting control system 20 are in a state of being constantly operated by being activated. First, the operation in the entrance / exit management system 11 will be described.

  When an employee or the like enters the room 2, the employee or the like holds an employee ID card or the like over the card reader 5 installed at the entrance / exit. In the present embodiment, each employee is assumed to enter the room from the entrance / exit closest to the place where his / her desk 7 is located. When the card reader 5 reads the identification information recorded on the employee ID card or the like, the card reader 5 transmits the read identification information to the ID controller 6. When the identification information is transmitted, the ID controller 6 compares the identification information with the personal information stored therein to perform user authentication. If the authentication is successful as a result of the authentication, the electric lock 3 of the door 4 at the doorway is unlocked, and entry into the room 2 is permitted. Then, the ID controller 6 transmits to the entrance / exit management system 11 traffic information including the date and time of traffic, the traffic type (in this example, “entry”), identification information of the user who has passed, name, affiliation, and the like. In this way, the traffic type is generated each time the user enters the room, and is transmitted to the entrance / exit management system 11.

  When the entrance / exit management system 11 is sent from the ID controller 6, a section name (in this example, an entrance or door 4) that identifies the place where the entrance has been made can be specified from the identification information of the ID controller 6. To generate traffic history information and store it in an internal traffic history information storage unit (not shown). In the above processing, the traffic history information accumulated in the traffic history information storage unit is generated with the above data structure. For example, personal information such as time, name, affiliation and the like is entered / exit management system 11 side. May be added.

  The function for managing the person's entry into the room 2 as described above is realized by the ID controller 6, its connected devices, and the entrance / exit management system 11. This function uses the previous entrance / exit management system as it is. May be realized.

  Next, the operation in the illumination control system 20 will be described. When the employee who first enters the room 2 at the start of work hours is allowed to enter the room 2 as described above, the door is turned on in order to turn on the light 8 corresponding to the position of the desk 7. The corresponding switch 9 is operated from the switch panel beside 4. In the present embodiment, it is assumed that only the lighting 8 corresponding to a certain position of the desk 7 is turned on. When the controller 12 detects this user operation, the controller 8 turns on the illumination 8 corresponding to the operated switch 9. The controller 12 transmits operation information including illumination identification information to the illumination control system 20 as information for specifying the date and time of operation based on this operation, the operation type (“lighting” in this example), and the operated illumination 8. . When the operation information is sent, the illumination control system function processing unit 32 in the illumination control system 20 stores the operation information as operation history information in an internal operation history information storage unit (not shown). The operation history information is also information for specifying the position of the illumination 8 corresponding to the operated switch 9, and is used as facility position information described below.

  The present embodiment is characterized in that, in conjunction with the entrance / exit management system 11, it is detected that the seat (the installation position of the desk 7) for specifying the location of the employee has moved, and is notified to the administrator. This process will be described with reference to the flowcharts shown in FIGS.

  When any one of the switches 9 is operated, the lighting control system function processing unit 32 generates the operation history information as described above, and immediately passes the generated operation history information to the equipment position information acquisition unit 33. The equipment position information acquisition unit 33 acquires the operation history information sent from the lighting control system function processing unit 32 as equipment position information for specifying the position of the lighting 8 corresponding to the operated switch 9 (step 110). . When the facility position information acquisition unit 33 detects that the facility position information has been acquired, the traffic history information acquisition unit 34 immediately acquires the traffic history information from the entrance / exit management system 11 (step 120).

  The employee is authenticated by holding the employee card over the card reader 5, thereby generating traffic history information. Subsequently, the employee operates the switch 9 corresponding to the arrangement position of his / her desk 7 in order to enter the room 2 and turn on the lighting 8, thereby generating operation history information. In step 110 and step 120, operation history information and traffic history information generated by this series of employee operations are acquired, and the following processing is performed in association with these pieces of information.

  Note that in the relationship between the operation history information and the passage history information to be associated, the operation history information acquired in step 110 is generated after the passage history information acquired in step 120. Therefore, strictly speaking, it is necessary to acquire the traffic history information generated immediately before the operation date and time set in the operation history information.

  When the operation history information and the traffic history information are acquired, the learning unit 35 specifies the illumination 8 corresponding to the operated switch 9 from the operation history information. Furthermore, the learning unit 35 specifies the user who has operated the switch 9 located near the door and the door 4 and the door 4 that has entered the room 2 from the traffic history information (step 130). In the present embodiment, the user who has entered the room 2 from the door 4 immediately before the operation of the switch 9 is detected in this way is regarded as the user who has operated the switch 9 installed on the side of the door 4. .

  If the user, the door 8 that the user entered / exited into the room 2 and the lighting 8 corresponding to the switch 9 operated by the user can be identified, the learning unit 35 performs the following learning (step 140), The learning result is stored in the learning information storage unit 38 (step 150).

  FIG. 7 is a diagram illustrating an example of a data configuration of learning results stored in the learning information storage unit 38 according to the present embodiment.

  That is, the learning unit 35 performs learning described later to obtain three types of learning results. First, for example, a cumulative learning value representing the strength of association for a combination of a user and each door, such as user a, door A, and door B, is obtained as the user-door association degree. First, for example, a cumulative learning value representing the strength of association for a combination of a user and each illumination such as the user a, the illumination 8a, and the illumination 8b is obtained as the user-illumination association degree. The other is, for example, a cumulative learning value representing the strength of association for the combination of the door and each light such as the door A, the light 8a, and the light 8b is obtained as the door-light relevance degree. The specific contents of learning are as follows.

First, as a user-door relevance degree, a learning cumulative value between the user and each door is calculated for each door. The learning accumulated value is obtained by the accumulated value, the differential value, and the accumulated deviation of the traffic amount (number of times of entering each door) of each door, as expressed by the following equation.
x [t] = x [t−1] + (a × Δy × | z [t] ⁻¹ |)
However,
x: Learning cumulative value. x [0] = Accumulated value of traffic at the start of calculation y: Traffic. Δy is a fluctuation value of the traffic amount during a certain period (Δt). There are positive and negative.
z: Deviation value of traffic amount a: Learning sensitivity adjustment parameter (constant)
t: time

  For the deviation, a discrete deviation value is calculated from the standard deviation based on the amount of traffic in the past fixed period. For example, the deviation takes the following values. In other words, if the number of users entering or exiting the door 4 that is not frequently used increases rapidly, the number rapidly increases. If the traffic volume remains high, the value stabilizes. When the number of users entering and exiting the door 4 that is frequently used is reduced, it gradually decreases. As the deviation of the door 4 where traffic has ceased increases, it rapidly decreases. After a certain period of time, the traffic volume does not fluctuate and the value stabilizes.

  FIG. 8 is a graph showing the relationship between time and the degree of user-door relevance represented by the cumulative learning value described above. A solid line and a wavy line indicate cumulative learning values of different doors A and B for the same user a. It means that the larger the accumulated learning value representing the degree of user-door relevance is, the more times the user enters the room through the door. According to the example shown in FIG. 8, at the beginning of learning, the user a frequently uses the door A, but the accumulated learning value of the door A decreases as the number of times the door A is used decreases. As the number of times B is used increases, the cumulative learning value of the door B increases, and as a result, the cumulative learning value at the point D is replaced.

  The learning cumulative value is calculated by repeating learning with the same calculation method for the user-lighting degree and the door-lighting degree. Note that the above-described learning method for obtaining each degree of association is an example, and is not necessarily limited to the above calculation formula.

  Each time the switch 9 is operated, the above learning is performed, and each degree of association is sequentially updated. In the present embodiment, while the above process is always executed, the process shown in FIG. 6 is separately executed as a scheduled process. In the present embodiment, the change detection unit 36 executes the process shown in FIG. 6 once a day, for example, at a predetermined time on each day.

  First, the change detection unit 36 refers to the user in the user-door association degree table shown in FIG. 7 and the learning value of each door, and compares the accumulated learning values for one day to be detected (step 210). And when the door which becomes the maximum value is not replaced (N in Step 220), it is determined that there is no change in the door used by the user. There is no change, so notification to the administrator is not necessary.

  On the other hand, by recognizing that the door having the maximum accumulated learning value has been replaced (Y in step 220), it is detected that the related strength relationship regarding the combination of the user and the door has changed. According to the example shown in FIG. 8, the detection is performed at the detection point D where the maximum value of the accumulated learning value is switched. This means that the frequency of use of the door used by the user has changed, that is, that the user has changed the door 4 used so far, the door used by the user's seat until now Is likely to have moved to a seat near another different door. Therefore, in the present embodiment, the replacement of the door 4 that is the maximum accumulated learning value is regarded as the seat of the user moving. In this case, the notification unit 37 notifies the manager terminal 13 by transmitting information indicating that a change in the related strength relationship regarding the combination of the user and the door has been detected (step 230). The user-lighting relevance level and the door-lighting relevance level are processed in the same manner.

  As described above, the occurrence of a change in the related strength relationship regarding the combination of the user and the door is considered to be highly likely that the user's seat has moved. Therefore, in the present embodiment, when a change in the related strength relationship regarding the combination of the user and the door is detected, the administrator is notified. The manager who has received this notification confirms whether the seat is moving, and if the administrator can confirm that the seat is actually moving, the administrator may update the database used by the lighting control system for lighting control. In other words, the administrator can know the possibility of movement of the employee's seat only by waiting for a notification from the lighting control system 20 without making an inquiry to each department or visiting each room. Depending on the management / operation method of the lighting control system, there may be a mechanism in which the database user is requested to update the database from the user side of the room to the manager. In such a case, the manager can estimate the employee's destination as preliminary information before receiving an update request, and can use it as information useful for database update.

  In the present embodiment, the user-door relevance degree is used as an index for determining whether or not the seat has moved. However, in FIG. 1, for example, when a certain user moves from the island 10a of the desk 7 to the island 10b, the use frequency of the user's door B may increase, but the user may continue to use the door A. There is a possibility that the movement of the seat will not be detected even if it is learned. In this case, referring to the user-lighting relevance level, a change appears in the lighting 8 corresponding to the switch 9 operated by the user, so that the movement of the seat can be detected. For example, if the user moves from the position of the illumination 8b on the island 10a of the desk 7 to the position of the illumination 8d on the island 10b, the user may continue to use the door A, but the switch 9 of the illumination 8b can be operated. On the other hand, the number of times the switch 9 of the illumination 8d is operated increases rapidly. Therefore, even if the movement of the seat is not detected only by the relationship between the user and the door A, the possibility of the movement of the seat can be found by referring to the relationship between the user and the lighting 8d (or the lighting 8b). become able to.

  Here, the degree of user-lighting relevance is information that clarifies the relationship between the user and the light 8, and is considered to be very effective information for knowing the possibility of movement to the seat. However, since the user-lighting relevance level is information based on operation history information obtained only when the user operates the switch 9, the operation history information is provided to employees who work late than other employees. May not be obtained at all. On the other hand, the degree of user-door relevance is an index obtained from the traffic history information. This traffic history information is information that is reliably collected every time the user enters the room 2. Therefore, in the present embodiment, without detecting the possibility of seat movement only by the user-lighting degree, only the user-door degree, or the user-door degree and the user-lighting degree are detected. The possibility of moving to the seat is detected by using both the index of degree. This is not to use only the user-door association degree as the cumulative learning value to be compared in step 210, but to obtain and compare the added value of the user-door association degree and the user-lighting association degree. Of course, instead of simply adding, it is also possible to add after weighting any degree of association. That is, the data to be compared in step 210 is not limited to comparing each relevance level alone, but the user-door relevance level, the user-lighting relevance level, and the door-lighting relevance level are obtained in any combination. You may do it.

  Furthermore, in this embodiment, a comparison was made using the accumulated learning value at the time of execution of the scheduled process shown in FIG. 6, but for example, the accumulated learned value at the time of the scheduled process performed in the past is stored, In step 210, a comparison may be made in consideration of past accumulated learning values.

  Further, the door-lighting degree of association is useful information for grasping a change in the layout of the room 2, for example. As described above, it has been described that the switch panel provided on the side of each door A, B, C in FIG. 1 includes the switch 9 of the illumination 8 close to each door A, B, C. It is possible to detect the possibility that the configuration of the device has changed.

  Hereinafter, a specific example will be described.

  Consider a user X who has a large amount of traffic for both door A and door B (high frequency of use) but rarely turns on lighting. FIG. 9 shows the relationship between the relevance levels in this case. In FIG. 9, it is assumed that the relevance is high in the order of high relevance, medium relevance, and low relevance. In this example, it is assumed that the user X uses the door A most frequently and uses the door B subsequently. In this case, since the cumulative learning value of [X]-[A] and [A]-[a] is maximized in the relationship between the user X and each of the lights a and b, the desk of the user X Estimated to be in the area. When the usage frequency of the door B becomes higher than that of the door A (that is, [X]-[A] is the medium relevance level and [X]-[B] is the high relevance level), and the cumulative learning value is reversed, the user The seat position of X is estimated to have moved to the area of illumination b, and this is notified to the administrator. If the degree of association between ([X]-[A], [A]-[a]) and ([X]-[B], [B]-[b]) is antagonizing, the reversal is Since the possibility of frequent occurrence arises, the learning sensitivity adjustment parameter (a in the above equation) may be adjusted to prevent the notification from being overrun.

  Next, when the layout inside the room 2 is changed, the relationship between the door A and the illumination a is reduced ([A]-[a] is a low relevance), and the relationship with the illumination c is increased ([A]-[ FIG. 10 shows the relationship between the relevance levels of [c] is the high relevance level). When the strength relationship of each relevance level is switched as in this example, it is estimated that the layout has changed, and the seat position of the user X is estimated to have moved to the area of the lighting c, and these facts are notified to the administrator. Notice.

  In the present embodiment, it is possible to detect the possibility of moving the seat as described above and notify the administrator to that effect.

  In the present embodiment, the case where the information providing measure according to the present invention is incorporated in the lighting control system 20 has been described as an example, but may be configured as a separate device. In this embodiment, lighting has been described as an example of equipment, but may be applied to other equipment installed in the room 2 such as air conditioning.

  Another embodiment of the information providing apparatus of the present invention will be described. In the information providing apparatus described above, the degree of association was calculated when the equipment position information was acquired.In this embodiment, the traffic history information when there is no equipment position information is also the target of calculating the degree of association. When there is equipment location information, the degree of relevance is calculated greatly.

Moreover, in this embodiment, the lighting control system 20 is registered in advance in the database with the desk 7 and the corresponding lighting 8 being located for each user, and receives the traffic history information from the entrance / exit management system 11 when the user enters the room. The lighting 8 at the location of the user is controlled to automatically turn on. That is, in FIG. 1, it is assumed that the initial user location is the desk 7 in the area of the lighting 8b on the island 10a. In this case, when the user enters the room from any one of the doors A to C, the illumination control system 20 automatically turns on the illumination 8b (if not illuminated).

  When the user enters the room, the entrance / exit management system 11 reads the user's identification card as described above, the date / time information specifying the date / time of passing, the user's user identification information, and the passage history including the door identification information identifying the entrance / exit Information is generated, stored and managed inside, and transmitted to the lighting control system 20. The lighting control system 20 receives the traffic history information, queries the database for the user identification information, and lights up when the lighting 8b is not lit and maintains it as it is when the lighting 8b is lit. Thereby, the user can start work at the seat without requiring the operation of the switch 9.

  Further, the traffic history acquisition unit 33 of the lighting control system 20 receives the traffic history information every time the user enters the room and sends it to the learning unit 35. The learning unit 35 determines the degree of association between the user identification information and the door identification information included therein. calculate. Since the degree of association is calculated according to the door through which the user has passed, in this embodiment, there are three types of combinations of the user identification information and the door identification information of the doors A to C.

  The calculation result of the learning unit 35 is stored as a cumulative value for each combination in the learning information storage unit 38. Here, since the initial location of the user is the island 10a, the degree of association between the user and the door A (the degree of association between the user identification information and the door identification information) is initially stored as the highest value, If there is no change, it should not change.

  On the other hand, for example, when the user passes through door B exclusively, the cumulative value of the learning information storage unit 38 based on the calculation result of the learning unit 34 indicates that the degree of association between the user and door B is greater than the degree of association with door A. Become. The change detection unit 36 detects such a change. And the notification part 37 notifies that the user may have moved to the door B side.

  However, it is possible that the user may select the door 4 regardless of the movement of the seat, and it may take a considerable amount of time to detect the change. Improve accuracy.

  For example, it is assumed that the user's seat has moved to the desk 7 in the area of the lighting 8f on the island 10c. Here, if the movement of the user is not changed and registered in the database of the lighting control system 20, the lighting 8f is not turned on even if the user enters the room. In that case, the user must turn on the illumination 8f by operating the switch 9 in the vicinity of the door B after entering the room.

  When the user operates the switch 8 near the door B to turn on the lighting 8f, the lighting control system function processing unit 32 determines whether the target lighting is the specific lighting registered in the database based on the facility position information obtained from the operation information. Determine whether or not. In this case, since it is the illumination 8b that is initially registered in the database, it is determined as NO.

  In addition, the equipment position information acquisition unit 33 acquires equipment position information including a determination result that the lighting is not specific lighting, and sends the equipment position information to the learning unit 35.

In addition, when the learning unit 35 receives the equipment position information within a specific time later than the date and time information included in the traffic history information and includes a determination result that it is not specific lighting, the user identification information and the door identification information The relevance of is calculated to be much larger than usual. As a result, the accumulated value stored in the learning information storage unit 38 also becomes larger, exceeds the point D in FIG. 8 at an early stage, and has a degree of relevance in a substantially constant state on the right side thereof.
In this embodiment, the learning unit 35 determines whether or not the specific illumination is in the case where the equipment position information is within 15 seconds after 1 second from the date and time information. This time may be set to the time required for the user to read the identification card and enter the room, confirm the lighting state, and operate the switch, depending on the situation of the room, door, equipment arrangement, etc. You only have to set it.

  In addition, the change detection unit 36 estimates that the user has moved when the change is detected to a substantially constant state on the right side from the point D where the magnitude of the relevance shown in FIG. A change result with the 8f area as a destination candidate is sent to the notification unit 37, and a notification to that effect is transmitted from the notification unit 37 to the administrator terminal 13.

  In this embodiment, the destination candidate is estimated based on the comparison result of the user-door relevance level and the contents of the equipment position information. However, as in the above-described embodiment, the user relevance level and the lighting- The door relevance degree may be calculated, and the destination candidate may be estimated using the comparison result.

  As described above, according to the information providing apparatus according to this embodiment, in addition to the degree of association between the user and each doorway, using the operation information by the user, the presence / absence of movement of the seat and the probability of the destination are increased, and the user Since the manager is informed of the destination and the destination of the change as a result of the change, the administrator can use the information for updating the database.
