[Operation of First Embodiment]
Next, the operation of the facility management system 1 according to the present embodiment will be described.
First, the operation of the management apparatus 40 will be described with reference to FIG. FIG. 6 is a flowchart illustrating the entrance / exit determination processing of the management device according to the first embodiment.
In response to the determination request from the reader terminal 22, the management device 40 executes the entrance / exit determination process of FIG.

The determination processing unit 45 first obtains the destination management section ID from the section information in the storage unit 44 based on the door ID specified in the determination request (step 100), and also based on the user ID specified in the determination request. An entry / exit permission section ID is acquired from the determination information in the storage unit 44 (step 101).
Thereafter, the determination processing unit 45 compares the destination management section ID with the entry / exit permission section ID and confirms whether or not the destination management section ID is included in the entry / exit permission section ID (step 102).
Here, when the destination management section ID is not included in the entrance / exit permission section ID and it is determined that the entrance / exit is impossible (step 102: NO), the determination processing unit 45 ends the series of entrance / exit determination processes. To do.

  On the other hand, when the destination management section ID is included in the entry / exit permission section ID and it is determined that entry / exit is possible (step 102: YES), the determination processing unit 45 starts from the communication I / F unit 41 to the control device 30. The door is instructed to unlock the electric lock 23 of the door 21 (step 103). Thereby, the door 21 is unlocked and the user can move to the destination management section.

  In addition, when the determination processing unit 45 determines that the user can enter and leave the management section 20, the occupancy number updating unit 46 determines from the section information in the storage unit 44 based on the door ID specified in the determination request. The source management partition ID and the destination management partition ID are acquired (step 104).

Subsequently, the occupancy number update unit 46 subtracts one person from the occupancy number of the movement source management section ID in the occupancy information of the storage unit 44 and adds one person to the occupancy number of the movement destination management section ID. Thus, the number of people in these sections is updated and stored in the storage unit 44 (step 105), and a series of entrance / exit determination processing is completed.
As a result, the number of people in the movement source management section and the movement destination management section is updated in real time in accordance with the determination of whether the room can be entered or exited.

Next, the overall operation of the facility management system 1 will be described with reference to FIG. FIG. 7 is a sequence diagram showing the operation of the entire facility management system.
When a user operation with the ID card 10 is performed at the reader terminal 22 (step 110), a determination request is notified from the reader terminal 22 to the management device 40 accordingly (step 111).

In response to this determination request, the management device 40 determines whether the user can enter or leave the room in response to the determination request, and if it is determined that the user can enter or leave the room (step 112), the management device 40 instructs the electric lock 23 to unlock. (Step 113). Thereby, the electric lock 23 is unlocked (step 114).
In addition, the management device 40 updates the occupancy number of the movement source management section and the movement destination management section by the occupancy number update unit 46 (step 115).

  After that, the management device 40 manages the occupancy status notification trigger by the occupancy status notification section 47, and is stored in the occupancy information of the storage section 44 when the notification trigger arrives (step 120). The occupancy status including the set of the management section ID and the number of people in the room is notified to the air conditioning control device 50 (step 121).

In the air conditioning control device 50, the outside air intake amount calculation unit 51 calculates the outside air intake amount of the section according to the number of people in the room according to the occupancy status from the management device 40 (step 122), and the air conditioning control. The unit 52 calculates a target opening degree of the outside air intake valve of the section corresponding to the outside air intake amount (step 123), and air-conditions a valve opening instruction with the opening degree of the outside air intake damper as the target opening degree. The data is transmitted to the facility 60 (step 124).
The air conditioning facility 60 controls the outside air intake damper according to the valve opening instruction from the air conditioning control device 50 to adjust the valve opening to the target opening (step 125).

[Effect of the first embodiment]
As described above, in the present embodiment, in the management device 40, when the determination processing unit 45 determines that the user can enter and leave the management section in response to a determination request from the reader terminal 22, the number of people in the room The update unit 46 updates the number of people in the source management section and the destination management section and saves them in the storage unit, and the occupancy status notification unit 47 saves each number of people in the storage unit 44. Is periodically notified to the air conditioning control device 50.

Further, in the air conditioning control device 50, the outside air intake amount calculation unit 51 calculates the outside air intake amount required in the section corresponding to the number of people in the room, according to the number of people in the room notified from the management device 40. Based on the outside air intake amount, the air conditioning control unit 52 obtains a target opening degree related to the outside air intake damper of the air conditioning equipment 60 corresponding to the section so that the opening degree of the outside air intake damper becomes the target opening degree. The air conditioner 60 is controlled.
In the present embodiment, the configuration is shown in which the target opening degree of the outside air damper is changed according to the number of people in the room notified from the management device 40. However, the air conditioning control device 50 uses the outside air enthalpy and the indoor load state value. When the outside air intake control based on the above is performed, the minimum setting opening degree of the outside air intake damper may be changed according to the number of people in the room notified from the management device 40.

  Accordingly, the outside air intake amount can be automatically adjusted based on the number of people in each section updated in real time for each entry / exit determination. Therefore, compared with the case where the outside air intake control is turned on / off in conjunction with the person's entry / exit room, it is possible to incorporate an optimum intake amount according to the number of people existing in the section. For this reason, when the number of persons is small, an excessive intake amount is not taken in, and for example, the COS concentration can be adjusted without increasing the outside air load in the temperature control.

  In the present embodiment, the case where the management device 40 periodically notifies the air conditioning control device 50 of the occupancy status of each management section has been described as an example. It is not limited to this. For example, the occupancy status notification unit 47 may notify the air conditioning control device 50 of the occupancy status regarding the management section when the number of people in the occupancy is updated for an arbitrary management section. Thereby, the occupancy status can be notified only when the number of people in the room changes and it is necessary to execute new outside air intake control.

  Further, in the present embodiment, the case has been described as an example in which the management device 40 notifies the air conditioning control device 50 of the occupancy status indicating the number of people in each section. The situation level may be notified. The occupancy status level is a level indicating the result of threshold processing for classifying the number of people in a plurality of stages. When an arbitrary occupancy status level is assigned to an arbitrary division, the presence of the division is indicated. It can be seen that the number of rooms belongs to the preset number of people in the room.

Therefore, in the outside air intake amount calculation unit 51 of the air conditioning control device 50, if the target opening degree of the outside air intake damper for each occupancy status level is registered in advance as a table, the presence information notified from the management device 40 is obtained. The target opening according to the room status level can be calculated by a very simple process, and the processing load on the air conditioning control device 50 can be greatly reduced.
Note that the threshold processing for deriving the occupancy level from the number of people in the room may be executed by the outside air intake amount calculation unit 51 of the air conditioning control device 50 instead of the management device 40.

[Second Embodiment]
Next, the facility management system 1 according to the second embodiment of the present invention will be described.
In the first embodiment, a case has been described as an example in which a management section, which is a management unit for entering and leaving a room, and an air conditioning section, which is a control unit for air conditioning control, have a one-to-one correspondence. In the present embodiment, a case will be described in which these management sections and air conditioning sections do not correspond one-to-one.

  FIG. 8 shows another configuration example of the partition. Here, as in FIG. 3, seven management sections R1-R7 are arranged so as to surround the shared portion. In the present embodiment, among these management sections R1-R7, the management sections R1-R3 are collectively controlled by the same air conditioning equipment 60 as one air conditioning section K1, and the management sections R4-R7 are one air conditioning section. The air conditioning is collectively controlled by the same air conditioning equipment 60 as K2.

  Such a correspondence relationship between the management section and the air conditioning section is registered in advance as air conditioning section information in the storage unit 44 of the management apparatus 40. FIG. 9 is a configuration example of air conditioning section information. Here, for each management section ID for identifying the management section, an air conditioning section ID indicating an air conditioning section corresponding to the management section is registered.

  FIG. 10 is a configuration example of the air-conditioning occupancy information. Here, for each air conditioning section ID for identifying each air conditioning section, the total number of people present in the management section belonging to the air conditioning section is registered as the number of people in the room. The number of people in the room is updated according to the entry / exit of the person in each management section belonging to the air conditioning section.

  In the present embodiment, the occupancy number update unit 46 of the management device 40 has a function of updating the occupancy number for each air conditioning section instead of the management section when updating the occupancy number. Specifically, when the determination processing unit 45 determines that the user can enter or leave the management section 20 in response to a determination request from the reader terminal 22, the information is stored based on the door ID specified in the determination request. By referring to the function of acquiring the movement source management partition ID and the movement destination management partition ID from the partition information of the unit 44 and the air conditioning partition information of the storage unit 44, the movement source management partition ID and the movement destination management partition ID It has a function of identifying the corresponding movement source air conditioning section ID and the movement destination air conditioning section ID.
