Description

  The present invention relates to an air-conditioning control technique, and more particularly to an air-conditioning set temperature calculation technique for automatically calculating an air-conditioning set temperature according to the preference of a room occupant.

  Conventionally, as an air conditioning control technology according to the preference of the occupant, when the occupant is personally identified and air-conditioning is performed so as to achieve the optimum environmental conditions according to the occupant's personal preference, a camera provided indoors At least one of the information on the occupants and the information on the occupants who have been detected by the camera provided outside the room, and are individually identified based on the information on the occupants or the occupants. A technique for controlling the continuous rotation of an air conditioner based on information about a room person or a room person has been proposed (see, for example, Patent Document 1).

  In addition, personal information including the sex and age of the user acquired from the entrance / exit management system is acquired, and the users are classified and aggregated by sex and by age for each room, and the total results and metabolic rate by age by sex A technique for controlling the operation of the air conditioner by correcting the output amount from the air conditioner based on a preset reference count in consideration of the above has been proposed (see, for example, Patent Document 2).

JP 2005-172288 A JP 2013-088105 A

  However, in such a conventional technique, general trends related to air conditioning control are estimated for each gender and age, and correction counts corresponding to these tendencies are set in advance for each gender and age. The set temperature of the room is corrected based on the correction count of each occupant specified based on the personal information, so the personal preference of the occupant cannot be directly reflected in the set temperature. There was a problem.

For example, just because a resident is in his twenties does not mean that every resident prefers stronger air conditioning, but just because a resident is a woman, all resident are weaker. I don't like air conditioning. Each occupant has a personal preference for air conditioning control.
The present invention is for solving such problems, and an air conditioning set temperature calculation technique for calculating an air conditioning set temperature that sufficiently reflects the personal preference of each room occupant for air conditioning control. It is intended to provide.

  In order to achieve such an object, the air conditioning set temperature calculation apparatus according to the present invention stores, for each user who uses the target section, the user's preference set temperature related to the air conditioning set temperature as a user-specific preference set temperature. Based on the temperature DB and the occupancy status acquired from the entry / exit management system that manages the entry / exit of the target section, a resident identification unit that identifies a user in the target section as a resident The user-specific preference temperature for the user identified as the occupant is acquired from the preset temperature DB, and the user-specific preference temperature is statistically processed to calculate a new preset temperature for the target section. A set temperature calculation unit for notifying an air conditioning system that controls the air conditioning environment of the target section.

  In addition, according to a configuration example of the air conditioning set temperature calculation device according to the present invention, when the set temperature calculation unit is less than a preset minimum number of people in the room, the air conditioning The notification of the new set temperature to the system or the calculation of the new set temperature is stopped.

  In addition, one configuration example of the air conditioning set temperature calculation device according to the present invention is directed to the air conditioning system when the set temperature calculation unit is not included in a preset temperature range in which the new set temperature is set in advance. The notification of the new set temperature is stopped.

  In addition, the air conditioning set temperature calculation method according to the present invention includes, for each user who uses the target section, a set temperature storage step of storing the user's preference set temperature related to the air conditioning set temperature as a user-specific preference set temperature in the set temperature DB; An occupant identification step for identifying a user in the target section as a resident based on the occupancy status acquired from the entrance / exit management system that manages the entrance / exit of the target section; User-specific preference temperature for a user identified as a room person is acquired from the preset temperature DB, and the user-specific preference temperature is statistically processed to calculate a new preset temperature for the target zone, and the target zone And a preset temperature calculation step for notifying the air conditioning system for controlling the air conditioning environment.

  Moreover, the program concerning this invention is a program for a computer to function as each part which comprises one of the air-conditioning preset temperature calculation apparatuses mentioned above.

  According to the present invention, a new set temperature related to the target section is calculated based on the preference set temperature registered in advance by each user in the target section. Therefore, when calculating the air conditioning set temperature compared to correcting the room set temperature with a correction count according to the gender and age of the occupants, each occupant has a personal control over the air conditioning control. It is possible to calculate the air conditioning set temperature that sufficiently reflects the preference. For this reason, it becomes possible to provide a more comfortable air-conditioning environment according to the preference of the occupants.

  In addition, in calculating a new set temperature, it is only necessary to register the preferred set temperature reported by each user in the set temperature DB. Based on the relationship with other users, a correction count and a weight are set for each user feature. Since it is not necessary to set in advance, the preparatory work burden required for calculating the set temperature can be greatly reduced.

Have.

  The entrance / exit management system 20 is a general entrance / exit management system that determines whether or not a user can enter / exit the target section 40 based on a user's card operation in a card reader installed at the entrance / exit of the target section 40. This entrance / exit management system 20 is based on the determination result of whether entrance / exit is possible or not, in response to a function for managing the occupancy status indicating the user in the target section 40 and an acquisition request from the air conditioning set temperature calculation device 10. Accordingly, it has a function of notifying the occupancy status to the air conditioning set temperature calculation device 10 via the communication line L.

  The air conditioning system 30 is a general air conditioning system that controls the air conditioning environment of the target section 40 by controlling the temperature and humidity of the air supplied to the target section 40. The air conditioning system 30 has a function of controlling the air conditioning environment of the target section 40 based on the set temperature notified from the air conditioning set temperature calculating device 10 via the communication line L.

Next, with reference to FIG. 1, the structure of the air-conditioning preset temperature calculation apparatus 10 concerning this Embodiment is demonstrated in detail.
The air conditioning set temperature calculation device 10 includes, as main function units, a communication I / F unit 11, an operation input unit 12, a screen display unit 13, a set temperature DB 14, an occupant identification unit 15, a set temperature calculation unit 16, A set temperature notification unit 17 is also provided.

The set temperature DB 14 is composed of a storage device such as a hard disk or a semiconductor memory, and has a function of storing various processing information used for air conditioning set temperature calculation as a database.
Main processing information stored in the set temperature DB 14 includes a user-specific preference set temperature and a section-specific determination criterion.

  FIG. 2 is a configuration example of the user-specific preference temperature. The user-specific preference temperature is a preset temperature of air conditioning that is set by each user and is preferred by the user. Here, for each user ID for identifying a user, a user name and a preference setting temperature are registered as a set. As for the preference set temperature, the cooling time and the heating time are individually registered.

  FIG. 3 is a configuration example of the determination criterion for each section. The determination criterion for each section is a reference for determining the reliability of the new set temperature calculated for the section for each section. Here, the minimum number of people in the room, the upper and lower limit temperature, and the lower limit temperature are registered as a set for each section ID for identifying the section. The upper and lower limit temperatures and the lower limit temperature are individually registered for cooling and heating.

  The minimum occupancy is the number of users who should be present in the target section 40. If the number of occupants of the user is less than the minimum occupancy, a new set temperature calculated from the user's preference set temperature Is determined to be unreliable due to poor reliability. The upper and lower limit temperatures and the lower limit temperature indicate the effective range of the new set temperature. If the upper and lower limit temperatures and the lower limit temperature are out of the range of the upper and lower limit temperatures and the lower limit temperature, it is determined that the new set temperature is not reliable and cannot be notified.

  As for these user-specific preference set temperatures and section-specific determination criteria, those input by the operator from the operation input unit 12 may be registered in the set temperature DB 14, and those created by an external device may be registered from the communication I / F unit 11.

  The occupancy status is updated by the entry / exit management system 20 when a user enters or exits the target section 40. For this reason, the occupancy status may be periodically acquired from the occupant identification unit 15 from the entry / exit management system 20, but the occupancy management system 20 notifies the air conditioning set temperature calculation device 10 according to the update, The occupant specifying unit 15 may acquire this.

  The set temperature calculation unit 16 statistically calculates the user-specific preference set temperature for the user identified as a resident by the occupant identification unit 15 from the set temperature DB 14 and the obtained user-specific preference set temperature of the user.

  The set temperature notification unit 17 has a function of notifying the air conditioning system 30 of the new set temperature determined to be notified by the set temperature calculation unit 16 via the communication I / F unit 11 and the communication line L. Yes.

[Operation of this embodiment]
Next, with reference to FIG. 5, operation | movement of the air-conditioning preset temperature calculation apparatus 10 concerning this Embodiment is demonstrated. FIG. 5 is a flowchart showing the air conditioning set temperature calculation process.
The air conditioning set temperature calculation device 10 executes the air conditioning set temperature calculation processing of FIG. 5 periodically or according to a change in the occupancy status for each preset target section 40. In executing the air conditioning set temperature calculation process, it is assumed that the user-specific preference set temperature and the section-specific determination criteria are registered in advance in the set temperature DB 14.

  First, the occupant specifying unit 15 acquires the occupancy status from the entrance / exit management system 20 via the communication I / F unit 11 and the communication line L (step 100), and based on the occupancy status, The user who is in the room is specified as a person in the room (step 101).

  Next, the set temperature calculation unit 16 acquires a user-specific preference set temperature related to the user specified as a resident by the occupant specifying unit 15 from the set temperature DB 14 (step 102), and acquires the acquired user-specific user-specific temperature. A new set temperature for the target section 40 is calculated by statistically processing the preferred set temperature (step 103). At this time, regarding the statistical process for the user-specific preference temperature, a process for calculating a representative value representing the user-specific preference temperature, such as an average value or a mode value, may be used.

  Subsequently, the set temperature calculation unit 16 acquires a section-specific determination criterion for the target section 40 from the set temperature DB 14 (step 104), and based on this section-specific determination criterion, to the air conditioning system 30 having the calculated new set temperature. Whether or not notification is possible is determined.

First, the minimum occupancy number included in the section-by-zone determination criteria is compared with the occupancy number by the user identified as a occupant by the occupant identification unit 15 (step 105).
Here, when the number of people in the room is lower than the minimum number of people in the room (step 105: NO), it is determined that notification is impossible, and the series of air conditioning set temperature calculation processing is ended. Thereby, the notification of the new set temperature to the air conditioning system 30 can be automatically stopped, and the disturbance of the air conditioning environment that may occur in the target section 40 can be avoided in advance.

On the other hand, when the number of people in the room is equal to or greater than the minimum number of people in the room (step 105: YES), the set temperature calculation unit 16 calculates the upper and lower limit temperatures and the lower limit temperatures included in the section-specific determination criteria and the calculated new set temperature. Compare (step 106). At this time, in step 106, the cooling time and the heating time are individually compared.
Here, when the new set temperature is outside the range of the upper and lower limit temperatures and the lower limit temperature (step 106: NO), it is determined that the notification is impossible, and the series of air conditioning set temperature calculation processing ends. Thereby, the notification of the new set temperature to the air conditioning system 30 can be automatically stopped, and the disturbance of the air conditioning environment that may occur in the target section 40 can be avoided in advance.

  On the other hand, when the new set temperature is within the range of the upper and lower limit temperatures and the lower limit temperature (step 106: YES), the set temperature calculation unit 16 outputs the new set temperature to the set temperature notifying unit 17, thereby communicating. The air conditioning system 30 is notified via the I / F unit 11 and the communication line L (step 107), and a series of air conditioning set temperature calculation processing ends.

  FIG. 6 is an example of calculating the air conditioning set temperature. Here, the number of people in the target section 40 of the section ID “0001” is 12, the cooling set temperature is calculated as 22 ° C., and the heating set temperature is calculated as 25 ° C. Here, in the judgment criteria according to the section relating to the section ID “0001” in FIG. 3, the minimum number of people in the room is 5, the upper and lower limit temperatures and the lower limit temperature during cooling are 29 ° C. and 23 ° C., respectively, Upper and lower limit temperatures and lower limit temperatures are 25 ° C. and 20 ° C., respectively.

  Therefore, in this example, it is determined that the number of people in the room and the heating set temperature satisfy the criteria, but the cooling set temperature does not meet the criteria. For this reason, when the air conditioning system 30 performs the heating operation, the heating set temperature is notified to the air conditioning system 30, and when the cooling operation is performed, the cooling set temperature is not notified to the air conditioning system 30.

  In the air conditioning set temperature calculation process of FIG. 5, the processing procedure may be changed as necessary. For example, in the example of FIG. 5, after calculating the new set temperature in step 103, the number of people in the room is compared with the minimum number of people in the room, but the new set temperature is not used for this comparison. The comparison may be performed after obtaining the determination criteria in step 104 after step 101 and before step 103. As a result, when the number of people in the room is less than the minimum number of people in the room, it is possible to omit the process of obtaining the preference set temperature in step 102 and the process of calculating the new set temperature in step 103.

[Effects of the present embodiment]
As described above, in the present embodiment, for each user who uses the target section 40, the set temperature DB 14 stores the user's preference set temperature related to the air conditioning set temperature as the user-specific preference set temperature. 15 identifies a user who is present in the target section 40 as a resident based on the occupancy status acquired from the entrance / exit management system 20, and the set temperature calculator 16 is identified as a resident. User-specific preference temperature related to the user is acquired from the preset temperature DB 14, and the user-specific preference temperature is statistically processed to calculate a new temperature setting for the target section 40 and notify the air conditioning system 30 of the new temperature setting. It is.

  Accordingly, a new set temperature for the target section 40 is calculated based on the preference set temperature registered in advance by each user in the target section 40. Therefore, when calculating the air conditioning set temperature compared to correcting the room set temperature with a correction count according to the gender and age of the occupants, each occupant has a personal control over the air conditioning control. It is possible to calculate the air conditioning set temperature that sufficiently reflects the preference. For this reason, it becomes possible to provide a more comfortable air-conditioning environment according to the preference of the occupants.

  Further, in calculating a new set temperature, it is only necessary to register the preferred set temperature reported by each user in the set temperature DB 14, and based on the relationship with other users, a correction count and a weight are set for each user feature. Since it is not necessary to set in advance, the preparatory work burden required for calculating the set temperature can be greatly reduced.

  Further, in the present embodiment, when the set temperature calculation unit 16 does not satisfy the preset minimum number of people in the room, the new set temperature is notified to the air conditioning system 30 or is newly set. It is also possible to cancel the calculation of a set temperature. As a result, when the number of people in the room is small and the reliability related to the new set temperature calculated is low, the notification of the new set temperature to the air conditioning system 30 can be automatically stopped and is generated in the target section 40. Possible disturbance of the air-conditioning environment can be avoided in advance.

  In the present embodiment, the set temperature calculation unit 16 stops notifying the air conditioning system 30 of the new set temperature when the calculated new set temperature is not included in the preset set temperature range. You may do it. Thereby, when the calculated new set temperature is out of the set temperature range and the reliability regarding the new set temperature is low, the notification of the new set temperature to the air conditioning system 30 can be automatically stopped, and the target section The disturbance of the air conditioning environment that may occur at 40 can be avoided in advance.

Various changes that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention. In addition, each embodiment can be implemented in any combination within a consistent range.

  For example, when the number of people in the room is less than the preset minimum number of people or when the calculated new set temperature is not included in the preset set temperature range, the air conditioning system 30 Instead of canceling the notification of the new set temperature, the air conditioning system 30 may be notified of the reference set temperature of the target section 40 that has been set in the set temperature DB 14 in advance.

  In the above description, the case where the target section 40 is commonly controlled by air conditioning over the entire area has been described as an example. However, when individual areas in the target section 40 can be controlled by a separate air conditioner, each user is controlled. An area normally present in the target section 40, for example, an area where the user's desk is present is registered in advance in the set temperature DB 14 as a home position, and the set temperature calculation unit 16 performs the process for each of the areas. Based on the user's preference setting temperature for each user who uses the area as the home position, a new setting temperature for the area may be calculated and notified to the air conditioning system 30.

  In the above, the case where the set temperature of the target section 40 is calculated has been described as an example. However, the present invention is not limited to this. Similarly to the set temperature, a new set air volume and a new set ventilation volume can also be calculated.

  In the above, the case where the air conditioning set temperature calculation device 10 is realized by a device independent of the entrance / exit management system 20 and the air conditioning system 30 has been described as an example, but the present invention is not limited thereto. For example, each functional unit of the air conditioning set temperature calculation device 10 may be mounted in the entrance / exit management system 20 or the air conditioning system 30.
