Abstract

To guide workers so as to form optimal population density, for each region having different air-conditioning temperature distribution.SOLUTION: Since an air conditioning system recognizes the preference data of the thermal sensation of a worker 24 by a questionnaire, etc. in advance, and further consider the attendance information of the worker 24 before the day of air conditioning control (for example, the day before), the air conditioning system can determine, on the day of the air conditioning control, a temperature range from the start of work (that is, from an initial stage), so as to adjust the air conditioning according to the worker 24 who works on the day of the air conditioning control. Consequently, the worker 24 can work at a comfortable temperature from the start of the work.SELECTED DRAWING: Figure 5

Description

  The present invention relates to an air-conditioning control system and an air-conditioning control program that can partition a living room space without partitions into a plurality of areas and air-condition each area with different temperature settings.

  For example, in air-conditioning control of a free-address type office, in consideration of individual differences in the thermal sensation of each worker, a set temperature is set for each area that divides one living room space, and the worker is given freedom of seat selection. It is known to The area has a temperature gradient in which the set temperature gradually changes in one direction (changes upward or downward) from one wall to the other wall of the living room space.

  Patent Literature 1 proposes a control unit that periodically reviews the area ratio (temperature gradient) of each set temperature region in order to avoid a population density becoming excessive in a specific set temperature region. I have.

  More specifically, Japanese Patent Application Laid-Open No. H11-163873 aims to keep the comfort of a user (worker) as much as possible when performing air conditioning control so as to form a plurality of air conditioning environment areas for one living room space. Forming a plurality of air conditioning environment areas in which different air conditioning environments are set in the living room space, and controlling the air conditioning equipment so as to change the distribution of the air conditioning environment areas in the living room space based on the determined distribution of the people. , The distribution status of a plurality of air conditioning environment regions in the space is displayed on a display device.

  In Patent Literature 1, the initial setting of the air conditioning environment at the start of operation is started from a predetermined fixed value because the attendance of the user on the day of the air conditioning control is not specified.

  In this regard, the paragraph number 0046 of Patent Document 1 states that "... the initial setting contents of the air-conditioning environment may be generated by a learning process using past results or the like." By averaging the distribution status of the air-conditioning environment area on the day with similar attributes (similar day), it is possible to generate some reasonable initial settings, but the workforce differs between the similar day and the day of the air-conditioning control. However, it is not possible to set the air conditioning environment area in accordance with the preference of the worker on the day of air conditioning control.

  Patent Literature 2 discloses that in an address environment of free address, one day of an employee registered in a schedule database for the purpose of supporting and promoting energy saving without forcing an employee (worker) to move a seat. It states that seats are allocated based on a schedule. More specifically, a configuration is described in which overtime employees are gathered in one place and air-conditioned.

  Even if an employee's day schedule registered in the schedule database described in Patent Literature 2 is used in Patent Literature 1, the air conditioning environment area is adjusted to the preference of each employee who works at the start of the air conditioning control day. I can't.

Japanese Patent Application Laid-Open No. 2014-85077 (Japanese Patent No. 5984011) JP 2013-186861 A

  For this reason, in the conventional air-conditioning control, the temperature is optimal, but the comfort may be low as a working environment due to overpopulation. Also, there may be workers who choose seats that have the right population density but not the best temperature. Further, with the review of the temperature gradient during the work, the seat may be moved, and the work efficiency of the work itself may be reduced.

  An object of the present invention is to provide an air conditioning control system and an air conditioning control program that can guide a worker so that an optimal population density is formed for each area having a different air conditioning temperature distribution.

  The air-conditioning control system according to the present invention is an air-conditioning control system corresponding to a free address office, and a database storing worker preference data on thermal sensation, and data on scheduled work of the worker on an air-conditioning control day, Setting means for setting an air-conditioning temperature distribution that divides a working space into regions having different set temperatures, based on the preference data and the going-to-work data, and based on the air-conditioning temperature distribution set by the setting means. Control means for controlling the air conditioning of the working space, and notifying means for notifying a worker of the air conditioning temperature distribution set by the setting means.

  In the present invention, the definition of “population” refers to the number of workers working in the area, and the definition of “population density” refers to the degree of density of workers working in the area.

  According to the present invention, the setting unit is configured to divide the working space into regions having different set temperatures based on the preference data of the worker regarding the thermal sensation and the schedule data of the worker on the air conditioning control day. Set the distribution.

  The control means controls the air conditioning of the working space based on the air conditioning temperature distribution set by the setting means, and notifies the worker of the air conditioning temperature distribution set by the setting means by the notifying means.

  Thereby, the workers can be guided so that the optimum population density (that is, the degree of the density of the workers working in the areas) is formed for each of the regions having different air conditioning temperature distributions.

  The present invention expands the area where the population is overcrowded on the day of the air conditioning control day, based on the actual worker population (ie, the number of workers working in the area) and distribution in the area, Further, it is characterized by further comprising changing means for changing the size of the area of the air-conditioning temperature distribution so as to reduce the area where the population distribution is sparse.

  In the changing means, on the day of the air-conditioning control day, based on the actual population and distribution of workers in the area, the area where the distribution of the population is dense is expanded, and the area where the distribution of the population is sparse is reduced. In addition, the size of the air conditioning temperature distribution area can be changed.

  In the present invention, the notifying unit further notifies the worker of the air conditioning temperature distribution changed by the changing unit.

  The worker can be notified of the air-conditioning temperature distribution changed by the changing unit from the initial state of the air-conditioning temperature distribution.

  The present invention is characterized in that it further comprises identification means for identifying the worker, and when the position of the identified worker is a predetermined exception area, the position is excluded from the change by the change means.

  For example, in the case where the position where the user temporarily works, such as a meeting, is changed, it is excluded from the change in the area of the air conditioning temperature distribution.

  In the present invention, further comprising identification means for identifying a worker, on the day of the air-conditioning control day, based on the result of selecting the area of the air-conditioning temperature distribution for each of the identified worker, stored in the database And updating means for updating the preference data.

On the day of the next air conditioning control day, an air conditioning temperature distribution area can be set based on the preference data updated by the updating means.
The present invention is characterized in that when the position of the identified worker is a predetermined exception area, the position is excluded from updating by the updating means.
For example, in the case where the position where the user is to work temporarily is changed, such as a meeting, the position is excluded from updating the preference data.

  In the present invention, the notifying unit notifies the air-conditioning temperature distribution via a display medium that can be browsed visually by the worker or a speech medium that can be heard by the worker through hearing.

  By installing the display medium and the utterance medium on the way to the free address office, the worker can go to the area of the air-conditioning temperature distribution that suits his / her preference.

  The present invention is characterized in that the notifying unit notifies the air conditioning temperature distribution by notifying a communication terminal carried by the worker.

  For example, when the temperature region of the air-conditioning temperature distribution is changed by the changing unit, the worker can be notified of the change in the temperature region of the air-conditioning temperature distribution by notifying the communication terminal carried by the worker.

  An air conditioning control program according to the present invention is characterized by causing a computer to operate as each function of the air conditioning control system according to the present invention.

  As described above, the present invention has an effect that a worker can be guided so that an optimal population density is formed for each region having different air conditioning temperature distributions.

  FIG. 1 is a schematic diagram of an air conditioning control system at a free address according to the present embodiment. The free address refers to a style in which a worker selects a seat in the office space, for example, in the office 10 as shown in FIG.

  In the office 10 having a free address, a network (for example, LAN or WAN) 12 is laid.

  The network 12 is connected to a worker monitoring control unit 14, a temperature monitoring unit 16, and an air conditioning control unit 18.

  The temperature monitoring unit 16 aggregates temperature information from each of the temperature sensors 20 attached to an appropriate part of the office 10.

  The air-conditioning control unit 18 controls each operation of the air-conditioning equipment 22 installed at an appropriate place in the office 10.

  The worker monitoring and control unit 14 grasps the attendance status of the worker 24 who works in the office 10, the working position of the worker who has gone to work, the temperature (thermal sensation) preference of each worker 24, and the like. Set the slope.

  It should be noted that the temperature gradient is easier to control when the inclination direction of the temperature change is constant so that the temperature gradually increases or decreases from one wall to the other wall, for example, so-called uneven shape. It does not deny setting the temperature in an annular shape.

  The air conditioner controller 18 controls the operation of each air conditioner 22 based on the temperature information from the temperature sensor 20 collected by the temperature monitor 16 so as to have the set temperature gradient. The ten spaces are divided into a plurality of temperature regions.

  Here, in the present embodiment, as an initial setting, all the workers 24 who are likely to work in the office 10 are surveyed (questionnaire) for the preference of thermal sensation, and a preference data profile is generated. It is managed by the preference data management unit 26.

  That is, in the preference data management unit 26, for example, as shown in FIG. 5A, when there is a possibility that a total of 12 workers 24 (workers 24A to 24L) may work in the office 10, Investigation of the thermal sensation preference data indicates that the worker 24 is comfortable at 24 ° C. (worker 24A to worker 24C), and the worker 24 at 26 ° C. is comfortable (worker 24D to worker 24I). ) And a worker 24 (worker 24J to worker 24L) that is comfortable at 28 ° C. is managed.

  (Adjustment control based on attendance status)

  FIG. 2 is a functional block for adjusting air conditioning according to a situation of a worker executed by a worker monitoring control unit (see FIG. 1). In FIG. 2, each control is divided into blocks for each function, and the hardware configuration of the worker monitoring control unit 14 is not limited. For example, part or all of the processing may be processing based on a software program (air conditioning control program).

  As shown in FIG. 2, the worker monitoring control unit 14 includes an attendant preference data reading unit 28, reads preference data of each worker 24 from the preference data management unit 26 (see FIG. 1), -Send to the number correlation specifying unit 32.

  The air-conditioning temperature-number-of-person correlation specifying unit 32 divides the office 10 into temperature areas having an area corresponding to the number of persons based on the attendees and taste data, and sends the divided areas to the initial temperature area determining unit 34.

  That is, the temperature region of 24 ° C. is set to the entire office area × (１ ／), the temperature region of 26 ° C. is set to the entire office area × (１ ／), and the temperature region of 28 ° C. is the entire office area × (1/4). (1/4) is set.

  In addition, the worker monitoring and control unit 14 includes an attendance confirmation unit 36, acquires attendance information on the day of attendance from the attendance schedule management unit 30, and sends it to the initial temperature area determination unit 34.

  The total number of the workers 24 who may work in the office 10 is 12, but not all of them work on the day of the air conditioning control.

  That is, some workers 24 may be absent due to going out or vacations.

  Therefore, in the present embodiment, the attendance schedule management unit 30 recognizes attendance information on the day of the air conditioning control. For example, as shown in FIG. 5 (B), the worker 24B who is comfortable at 24 ° C. is absent for going out, and the worker 24E who is comfortable at 26 ° C. is absent for going out, In addition, it recognizes that the worker 24L who is comfortable at 28 ° C. is absent for vacation.

  Therefore, the total number of the workers 24 working in the office 10 on the day of the air conditioning control is nine, the temperature area of 24 ° C. is set to the total office area × (2/9), and the temperature area of 26 ° C. is the entire office area. × (5/9), and the temperature region of 28 ° C. is set to the entire office area × (2/9) (see FIG. 5C).

  The initial temperature region determining section 34 determines an initial temperature of each of the divided temperature regions and sends it to the air-conditioning control instructing section 38. The air-conditioning control instruction unit 38 controls the air-conditioning control unit 18 to perform air-conditioning control.

  Further, the air-conditioning control unit 18 outputs information on the temperature region of the office 10 to the temperature region information notification unit 40 (see FIG. 1). As shown in FIG. 1, the temperature area information notifying unit 40 notifies the worker 24 of the information on the temperature area using the notifying means (the monitor 42 and / or the speaker 44).

  For example, a digital signage or the like as the monitor 42 is installed on the way to enter the office 10 (such as at the entrance of a building) to notify the temperature area information of the office 10 visually, or the speaker 44 installed on the way. , The temperature area information of the office 10 can be notified through hearing.

  By the time the worker 24 arrives at the office 10, he or she can grasp the temperature region of his / her preference and aim for a seat in the temperature region.

  As shown in FIG. 1, when the worker 24 has a portable terminal 46 (for example, a smart phone) and installs a temperature region notification application in advance, the communication I / F 48 is transmitted from the temperature region information notification unit 40. , The Internet 50, and the wireless communication device 51, the temperature range of the office can be notified to the portable terminal 46.

  (Adjustment control based on the worker's seating status "change of preference")

  As shown in FIG. 1, a transmission / reception unit 52 is connected to the network 12. The transmission / reception unit 52 is a short distance using an electromagnetic wave between the RFID tag 54 carried by each worker 24 (for example, a range of several centimeters to several meters covering part or all of the area of the office 10). And has a function of reading ID information identifying the worker 24 embedded in the RFID tag 54.

  On the day of the air-conditioning control, the workers 24 working in the office 10 (for example, the nine workers 24 whose attendance was clarified in FIG. 5B) have the temperature set for each preference (thermal sensation). It is assumed that a seat is selected from the area.

  However, the preference changes depending on the environment on the day of the air conditioning control of the worker 24, the health condition of the worker 24, and the like, and the worker 24 may select a temperature region different from the thermal sensation of the preference registered in advance. .

  Therefore, as shown in FIG. 2, the worker identification unit 56 of the transmission / reception unit 52 specifies the worker 24 (collation with the ID information) by communication with the RFID tag 54.

  Further, the transmitting / receiving unit 52 includes an intensity distribution capturing unit 58, which captures the intensity of the radio wave received from the RFID tag 54, and monitors the position of the worker 24.

  For example, as shown in FIG. 4, the position of the worker 24 can use the difference between the reception intensities of the plurality of transmission / reception units 52.

  That is, as shown in FIG. 4A, in the office 10, four transmission / reception units (the first transmission / reception unit 52A to the fourth transmission / reception unit 52D) correspond to the specific RFID tag 54 within the transmittable / receivable range. Consider the case where it exists.

  The communication strength of the first transceiver 52A is “strong”, the communication strength of the second transceiver 52B and the third transceiver 52C is “medium”, and the communication strength of the fourth transceiver 52D is “weak”. Suppose there was.

  As shown in FIG. 2, the transmitting / receiving section 52 is connected to the worker position specifying section 60, and as shown in FIG. 4B, the shorter the distance between the transmitting / receiving section 52 and the RFID tag 54, the more the communication. Since it is known that the strength is high, the position of the specific RFID tag 54 can be specified by drawing a circle corresponding to the communication strength centering on each transmission / reception unit 52 (see FIG. 4A). .

  In FIG. 4A, each area surrounded by a dotted-line grid indicates the resolution for specifying the position, and the minimum distance between the working seats, for example, 0.5 m to 1.0 m square. It is sufficient that the position of the worker 24 can be grasped for each area.

  As shown in FIG. 5D, when the position of the RFID tag 54 is known, the worker 24 in the office 10 can be identified and the position can be specified.

  At this time (FIG. 5D), the temperature gradient of the office 10 is set based on the attendance information on the day of the air-conditioning control and personal preference data. It is not taken into consideration that a different temperature region is selected, and some or all of the temperature regions do not have an area corresponding to the number of workers 24 (the situation on the day).

  In the present embodiment, by identifying each worker 24 working in the office 10 and grasping the position, each worker 24 works in the temperature region according to the preference data, or contrary to the preference data. Recognizing whether or not the user works in another temperature area, the area of the temperature area is changed with an exception (described later).

  That is, the worker position identification unit 60 is connected to the change necessity determination unit 62. The change necessity determination section 62 determines whether or not the area of the temperature region needs to be changed.

  Here, the exception information storage unit 64 is connected to the change necessity determination unit 62. The exception information storage unit 64 stores exception conditions that are not changed even when the position of the worker 24 is in a temperature region that is contrary to the preference data.

  As an example of the exceptional condition, there is a case where a plurality of workers having different preferences in a comfortable temperature region temporarily gather to have a meeting. The change necessity judging section 62 does not change the worker 24 in a predetermined meeting room in the office 10 (change unnecessary judgment).

  The change necessity determination unit 62 is connected to the temperature region change unit 66 and sends out the position of the worker 24 and the necessity information of the change. The temperature region changing unit 66 notifies the air conditioning control instruction unit 38 of the temperature region to be changed.

  For example, FIG. 6A shows a state before the change on the day (the same as FIG. 5D). Before the change on the day, the worker 24H and the worker 24I read the ID information of the RFID tag 54 and received the signal, and the worker 24H and the worker 24I were able to obtain a temperature of 28 ° C. even though the temperature range of 26 ° C. was comfortable in the initial taste data. You can see that you are working in the area.

  For this reason, the temperature region of 24 ° C. is in an appropriate state, the temperature region of 26 ° C. is in a sparse state, and the temperature region of 28 ° C. is in a dense state.

  Therefore, as shown in FIG. 6B, a temperature gradient in which the area of each temperature region is changed is set so as to narrow the temperature region of 26 ° C. and expand the temperature region of 28 ° C. (after the change on the day).

  After the change on the day, all the temperature regions are in the appropriate state, and all the workers 24 can execute the work under the comfortable temperature region.

  In this case, if the destination of the worker 24H and the worker 24I is a predetermined meeting room, the exceptional condition is satisfied, and no change is made.

  (Learning control)

  As shown in FIG. 2, the change necessity determination unit 62 is connected to the preference data update unit 68. In the preference data update section 68, when the change is necessary in the change necessity determination section 62, the preference data management section 26 is accessed to update the preference data of the worker 24 which causes the change.

  The update of the preference data of the worker 24 is not performed every time the worker 24 works in a different temperature region, and is performed N times (N is an integer of 2 or more) continuously in a different temperature region. It may be performed.

  The operation of the present embodiment will be described below with reference to the flowchart of FIG. In executing the air-conditioning control in the present embodiment, it is assumed that a preference database of the thermal sensation of the worker 24 has been generated in advance by a questionnaire or the like and stored in the preference data management unit 26.

  As shown in FIG. 3, in step 100, the worker 24 who goes to work on the day of the air conditioning control (for example, the next day) is confirmed.

  In the next step 102, the preference data (thermal sensation information) of the worker 24 who goes to work is read out based on the preference database stored in advance, and the process proceeds to step 104.

  In step 104, the correlation between the air-conditioning temperature and the number of persons is specified based on the preference data (thermal sensation information) for each worker 24, and the process proceeds to step 106 to determine the initial temperature region (temperature gradient). Then, the process proceeds to step 108.

  In step 108, the air conditioning control unit 18 instructs the air conditioning control of the air conditioning equipment 22 so as to be in the determined initial temperature range (temperature gradient).

  By the air-conditioning control based on this initial temperature range, as shown in FIG. 5C, a temperature gradient is formed with a correlation between the number of workers 24 and the temperature range in which each worker 24 feels comfortable. . That is, when the number of workers 24 having the same comfortable temperature is small, the area is narrow, and when the number of workers 24 having the same comfortable temperature is large, the area is wide.

  In the next step 110, the status of the temperature range where the air conditioning is controlled is notified to the worker 24 who goes to work. For example, a monitor 42 (digital signage, etc.) or a speaker 44 is installed in a building entrance, a passage, or the like, which always passes when the worker 24 goes to work, or in the office 10, and the worker 24 is notified. Can recognize the temperature range on the day of the air conditioning control.

  As described above, in order to recognize the attendance information of the worker 24 in advance and determine the temperature range and control the air conditioning in the initial stage in accordance with the worker 24 who goes to the office on the day of the air conditioning control and works. 24 can work at a comfortable temperature from the start of the work.

  By the way, there is no problem if the worker 24 sits and works in the temperature range as declared (responded to the questionnaire) as it is, but differs from the declared temperature range due to, for example, physical condition on the day of the air conditioning control. In some cases, the user prefers to sit in an area.

  Therefore, in the present embodiment, the temperature region is changed by identifying the worker 24 and specifying the position where the worker 24 is working.

  That is, in the next step 112, the worker 24 is identified by transmission / reception to / from the RFID tag 54 in the transmission / reception unit 52, and then the process proceeds to step 114 to capture the reception intensities of the plurality of transmission / reception units 52 and proceeds to step 116. .

  That is, as shown in FIG. 4 (A), a circle of a receiving distance corresponding to each intensity can be drawn according to the difference of the reception intensity, and the signal is transmitted from an overlapping point of a plurality of circles (worker 24). Is present).

  In step 116, the position of the identified worker 24 is specified based on the difference in reception strength, and the process proceeds to step 118.

  In step 118, the situation of the population density in each temperature region is determined, and it is determined whether there is a depopulated (or overcrowded) temperature region. In FIG. 5 (D), the workers 24H and 24I, which should originally work in the temperature range of 26 ° C., work in the temperature range of 28 ° C., and the temperature range of 26 ° C. becomes depopulated, and The temperature region of 28 ° C. is in an overcrowded state. In this case, an affirmative determination is made in step 118.

  If a negative determination is made in step 118, that is, for example, if all the workers 24 are sitting and working according to the predetermined preference data in the temperature area initially set on the day in FIG. 5C, the temperature area is changed ( Since there is no need to enlarge or reduce the size, the process proceeds to step 130.

  If an affirmative determination is made in step 118 (that is, a situation as shown in FIG. 5D), the process proceeds to step 120. In step 120, based on the exception information, it is determined whether or not the temperature area needs to be changed (enlarged or reduced), and the process proceeds to step 122 to determine whether or not the temperature area needs to be changed.

  For example, work in a space where a predetermined number of people or more gather, such as a meeting room, is determined to be temporary work, and an exception is made to a change in the temperature region.

  When a negative determination is made in step 122, that is, when it is determined that the change of the temperature region is unnecessary, the process proceeds to step 130.

  Further, if an affirmative determination is made in step 122, it is determined that at least on the day of the air-conditioning control, it will be permanently operated at the current location, and the process proceeds to step 124, where the temperature is changed to the size of the temperature region where the population density is averaged. . That is, the area of the dense environment is enlarged and the area of the sparse area is reduced (see the change from FIG. 6A to FIG. 6B).

  In the next step 126, the change status of the temperature region where the air conditioning is controlled is notified to the worker 24 who goes to work. In this case, since the worker 24 is already in the air-conditioned office 10, the worker 24 may notify the portable terminal 46 (smartphone or the like) carried by the worker 24, for example.

  In the next step 128, the preference data is updated based on the worker 24 located in the changed temperature region, and the process proceeds to step 130. Note that, here, the preference data is changed when the position where the worker 24 works is at least once in a different temperature range. However, it is also considered that the preference data is changed to a different temperature range only for that day due to physical condition or the like. Alternatively, a history of the temperature range in which the same worker 24 works may be kept for a certain period of time, and whether to change the preference data may be determined based on the history.

  In step 130, it is determined whether the air-conditioning control has ended on the day of the air-conditioning control, that is, whether or not the operation has ended, and if a negative determination is made, the process returns to step 112 and repeats the above steps.

  If an affirmative determination is made in step 130, the process proceeds to step 132 to instruct the air conditioning control unit 18 to end the air conditioning control of the air conditioning equipment 22, and this routine ends.

  As described above, in the present embodiment, the preference data of the thermal sensation of the worker 24 is recognized by a questionnaire or the like, and the attendance information of the worker 24 is provided before (for example, the day before) the day of the air conditioning control. In addition, on the day of the air-conditioning control, from the start of employment (that is, from the initial stage), the temperature range is determined and the air-conditioning control is performed in order to determine the temperature region according to the worker 24 who goes to the office and works. The person 24 can work at a comfortable temperature from the start of the work.

  Further, when the population density is depopulated, the area size can be changed (enlarged / reduced).

  Further, by notifying the change of the temperature region, the movement of the work position of the worker can be promoted.

  Further, based on the position where the worker 24 has actually worked, the worker's future preference data can be changed.

  Further, when the worker is working at a position contrary to the intention of the worker, such as a meeting, it can be excluded from the change of the preference data.
