FIG. 3 is a diagram for explaining a method for editing personal information in an entrance / exit controller of the entrance / exit management system used in the power management system according to Embodiment 1 of the present invention.

  As shown in FIG. 3, an edit screen 13 is displayed on the display unit of the entrance / exit controller 4. On the editing screen 13, a “personal number” field, a “name” field, and a “special person attribute” check box 14 are displayed. The personal information 10 is edited using these fields. That is, a personal number or the like is added, changed, or deleted.

  For example, when a personal attribute is a special attribute, “re” is added to the check box 14. If the personal attribute is not a special attribute, “Re” is removed from the check box 14. If the registration button 15 is selected in this state, the personal attributes are updated. If the cancel button 16 is selected, the displayed personal information 10 is deleted.

Next, the internal processing of the entrance / exit controller 4 will be described with reference to FIG.
FIG. 4 is a flowchart for explaining the internal processing of the entrance / exit controller of the entrance / exit management system used in the power management system according to Embodiment 1 of the present invention.

  In step S <b> 1, the entrance / exit controller 4 waits for a traffic notification from the entry card reader 2 or the exit card reader 3. When the entrance / exit controller 4 receives the traffic notification, the process proceeds to step S2. In step S2, the entrance / exit controller 4 searches the area information 11 with the card reader identifier specified in the traffic notification, and specifies the corresponding area number and the type of the card reader. Thereafter, in step S3, the entrance / exit controller 4 determines the type of the card reader.

  If the card reader is the incoming card reader 2 in step S3, the process proceeds to step S4. In step S <b> 4, the entrance / exit controller 4 adds a record having the area number and the personal number designated in the traffic notification to the area presence information 12.

  Thereafter, the process proceeds to step S5, and the entrance / exit controller 4 counts the number of records having “special person attribute” of “Yes” for all the personal numbers of the records having the area number existing in the area presence information 12. Thereafter, in step S6, the entrance / exit controller 4 sends the area number, the number of people in the area, and the number of records having “special person attribute” to “present” to the demand monitoring control device 8 as presence / absence information for each area. Notice. Thereafter, the operation from step S1 is repeated.

  If the card reader is the outgoing card reader 3 in step S3, the process proceeds to step S7. In step S7, the entrance / exit controller 4 deletes the record of the personal number specified in the traffic notification from the record having the area number specified in the traffic notification of the area presence information 12.

  Thereafter, the process proceeds to step S5, and the entrance / exit controller 4 counts the number of records having “special person attribute” of “Yes” for all the personal numbers of the records having the area number existing in the area presence information 12. After that, in step S6, the entrance / exit controller 4 monitors the demand by using the area number, the number of persons in the area, and the number of records having “special person attribute” in the area as “present” as presence / absence information for each area. The control device 8 is notified. Thereafter, the operation from step S1 is repeated.

Next, information managed by the demand monitoring control device 8 will be described with reference to FIG.
FIG. 5 is a diagram for explaining information managed by the demand monitoring control device of the building management system used in the power management system according to Embodiment 1 of the present invention.

  As shown in FIG. 5, the demand monitoring control device 8 manages demand control level information 17, area facility information 18, area occupant information 19, and demand control state information 20. The demand control level information 17, area facility information 18, area occupant information 19, and demand control status information 20 are stored on the memory of the demand monitoring control device 8.

  In the demand control level information 17, “usage amount”, “area number”, and “light control level” are associated with levels that determine priority within the demand time period. “Usage amount” is electric power used. The “area number” is an area number corresponding to an area belonging to the level. The “dimming level” is the ratio of the brightness to the total luminance of the illumination 7.

  In the area facility information 18, “air conditioner signal” and “light control signal” are associated with the area number. The “air conditioner signal” is an operation instruction signal for the air conditioner in the area corresponding to the area number. The “light control signal” is a signal related to the illuminance of the illumination 7 in the area corresponding to the area number.

  In the area occupant information 19, “the number of occupants” and “special number of people” are associated with the area numbers. “Number of people in the room” is the number of individuals in the area corresponding to the area number. The “special number of people” is the number of individuals whose “special person attribute” is “Yes” in the area corresponding to the area number.

  In the demand control state information 20, “control” is associated with a level. “Control” indicates whether or not the level is subject to demand control.

Next, presence / absence information reception processing for each area by the demand monitoring control device 8 will be described with reference to FIG.
FIG. 6 is a flowchart for explaining presence / absence information reception processing for each area by the demand monitoring control device of the building management system used in the power management system according to Embodiment 1 of the present invention.

  In step S11, the detection unit 8a waits for reception of the area number from the entrance / exit controller 4, the number of people in the area, and the number of records in which the “special person attribute” is “present”. Thereafter, in step S12, the control unit 8b updates the “number of occupants” and “special number of people” in the record of the area in the area occupant information 19.

Next, the demand control that is always performed by the demand monitoring control device 8 will be described with reference to FIG.
FIG. 7 is a flowchart for explaining demand control by the demand monitoring control device of the building management system used in the power management system according to Embodiment 1 of the present invention.

  In step S31, the control unit 8b predicts the power within the demand time period based on the power usage amount within the demand time period obtained from the power meter 9. First, the control unit 8b obtains a predicted value of power in a state where demand control is not performed at all levels. In step S32, the level (Lv value) is set to 1. In step S33, the control unit 8b determines whether or not the predicted power value exceeds the target value.

  If the predicted power value does not exceed the target value in step S33, the process proceeds to step S34. In step S34, the control unit 8b determines whether or not the level is the maximum level. If the level is the highest level in step S34, the operation from step S31 is repeated.

  If the predicted power value exceeds the target value in step S33, the process proceeds to step S35. In step S35, the control unit 8b refers to the area occupant information 19 from the area number of the level in the demand control level information 17, and refers to the “special number of people” in the area of the level. Thereafter, the process proceeds to step S36, and the control unit 8b determines whether or not the “special number of people” in the area is zero.

  If the “special number of people” in the area is 0 in step S36, the process proceeds to step S37. In step S <b> 37, the control unit 8 b determines whether the level is “present” or “not present” in the demand control state information 20.

  If the level is “none” in step S37, the process proceeds to step S38. In step S38, the control unit 8b updates the level in the demand control state information 20 to the control “present”. Then, it progresses to step S39 and the control part 8b controls the object installation of the area of the said level. For example, the control unit 8b outputs an air conditioner signal for turning off the air conditioner 6 and a dimming signal related to the dimming level of the illumination 7.

  When the level is “Yes” in step S37 and after step S39, the process proceeds to step S40. In step S40, the control unit 8b subtracts the power usage amount of the area of the level from the predicted power value.

  Then, it progresses to step S41 and the control part 8b increments Lv value. Then, it progresses to step S42 and the control part 8b determines whether the predicted value of electric power exceeded the target value.

  If the predicted power value does not exceed the target value in step S42, the operation from step S34 is repeated. On the other hand, if the predicted power value exceeds the target value, the process proceeds to step S43. In step S43, it is determined whether the level is the maximum level.

  If the level is not the maximum level in step S43, the operation from step S35 is repeated. On the other hand, if the level is the maximum level, the process proceeds to step S44. In step S44, the control unit 8b determines that an abnormal demand control abnormality has occurred. Thereafter, the operation from step S31 is repeated.

  If the “special number of people” in the area is not 0 in step S36, the process proceeds to step S45. In step S45, the control unit 8b determines whether the level is “present” or “not present” in the demand control state information 20.

  If the level is “Yes” in step S45, the process proceeds to step S46. In step S46, the control unit 8b updates the level in the demand control state information 20 to control “none”. Then, it progresses to step S47 and the control part 8b returns the object installation of the area of the said level. For example, the control unit 8b outputs an air conditioner signal for restoring air conditioning in the air conditioner 6 and a dimming signal for returning the dimming level of the illumination 7.

  In the case where the level is “none” in step S45 and after step S47, the predicted power value is maintained exceeding the target value. In this case, the operation from step S41 is repeated.

  If the level is not the highest level in step S34, the process proceeds to step S48. In step S <b> 48, the control unit 8 b determines whether or not the level is “control” in the demand control state information 20.

  If the level is “control”, the process proceeds to step S49. In step S49, the control unit 8b updates the level in the demand control state information 20 to control “none”. Then, it progresses to step S50 and the control part 8b returns the object installation of the area of the said level. For example, the control unit 8b outputs an air conditioner signal for restoring air conditioning in the air conditioner 6 and a dimming signal for returning the dimming level of the illumination 7.

  If the level is “none” in step S48 and after step S50, the process proceeds to step S51. In step S51, the control unit 8b increments the Lv value. Thereafter, the operation from step S34 is repeated.

  According to the first embodiment described above, based on the attributes of individuals in an area, the priority order when performing demand control of equipment in the area is temporarily changed. For this reason, demand control can be performed in consideration of an individual who exists in the area. As a result, discomfort can be reduced for special individuals.

  For example, when a cleaner, a coordinator, or the like is in a room that is not often used, or in a showroom that is usually unattended, the air conditioner 6 can be stopped to reduce the amount of power used. On the other hand, “special person attributes” may be set for important customers, overseas guests, senior executives of the company, and the like. In this case, when using a room in which these persons are not frequently used, such as a showroom that is usually unattended, the environment-related equipment such as the air conditioner 6 and the lighting 7 can be operated as usual.

  In addition, the authentication result of the entrance / exit management system 1 is used to enter and exit the area. For this reason, it is possible to reduce discomfort for a special individual while increasing the security of the area.

  In addition, when “special person attribute” is set for an individual who enters the area when the power supply to the facility in the area is cut off, the power is supplied to the facility in the area. For this reason, when a special individual enters the area, discomfort can be reduced for the special individual.

  Further, when a special individual leaves the area, the priority order when performing demand control of equipment in the area returns to the preset priority order. For this reason, fair demand control can be maintained.

  Note that the demand control may be performed based on the number of special individuals in the area after the level reaches the maximum level. In this case, an area with a small number of special individuals may be subjected to demand control preferentially over an area with a large number of special individuals. As a result, the effect of demand control can be obtained even when there are special individuals in all areas.

  In addition, special personal attributes may be set to multilevel levels. In this case, based on the level of a special individual who is present in the area after the level reaches the maximum level, the priority order for the demand control of the facilities in each area may be changed. For example, the most important customers may be given higher priority than senior executives in the company. In this case, the priority order for controlling the facilities in each area may be determined based on the sum of the levels of special individuals in the area or the level of the attributes of special individuals in the area.

  In addition, traffic may be permitted on a schedule for guests who suddenly visit. That is, you may designate the time slot | zone which permits passage of guests etc. with respect to the area where guests etc. may pass. In this case, a guest or the like is set as a special individual, and the facility in the area may be excluded from demand control even if the individual does not actually exist in the area in the time zone indicated by the schedule. At this time, the guest area may be cooled or warmed before the guest passes the area.

  The target of demand control may be equipment other than the air conditioner 6 and the illumination 7. That is, it is only necessary to associate the facilities subject to demand control with the facilities in the area where there is a possibility that a special person exists.

  In addition, an identification device other than a card reader may be used as long as it can identify an individual. For example, an individual may be identified based on the result of fingerprint authentication by the fingerprint authentication device.

  The power management system may be applied to buildings other than buildings such as factories.
