Only the controller 13 that manages the above is illustrated.

  FIG. 2 shows a control system configuration diagram in the air conditioning control support device according to one embodiment of the present invention. As shown in FIG. 2, this system is functionally divided and configured by processing blocks of a pre-registration unit 1121, an authentication unit 131, an electric lock / door control unit 132, a storage unit 110, and an air conditioning control unit 1201.

  The pre-registration unit 1121 has a function of registering information necessary for personal verification at the time of entry / exit authentication, such as card information, finger vein information, fingerprint information, ear shape information, and body temperature information, from the client machine to the storage unit 110. The body temperature is measured and stored in the storage unit 110 simultaneously with the registration of the authenticator's biometric authentication information. Body temperature measurement at the time of pre-registration uses finger vein authentication and fingerprint authentication to measure the voltage with a temperature sensor (thermistor) placed at the authentication site of the finger vein device for registration and the fingerprint device for registration. Convert and measure. In ear-shaped authentication, brightness (infrared heat radiation intensity) is measured by a temperature sensor (thermistor) disposed at an authentication site of the authentication device, and body temperature is converted from the measured brightness. The body temperature may be registered in the storage unit 110 by manual input from the client machine.

  The authentication unit 131 functions to read the card information, finger vein information, fingerprint information, ear shape information, etc. of the authenticator at the time of entrance / exit authentication, and collate with information pre-registered in the storage unit 110 by the pre-registration unit 1121 Have The body temperature is measured simultaneously with the verification of the certifier and stored in the storage unit 110. Body temperature at the time of authentication is finger vein authentication or fingerprint authentication. The finger vein authentication device and the temperature sensor (thermistor) placed at the authentication part of the fingerprint authentication device measure the voltage, and the body temperature is converted from the measured voltage. . In ear-shaped authentication, brightness (infrared heat radiation intensity) is measured by a temperature sensor (thermistor) disposed at an authentication site of the authentication device, and body temperature is converted from the measured brightness. In addition, the body temperature measurement at the time of authentication may be limited to the time of the first room entry authentication on that day.

  The electric lock / door control unit 132 has a function of performing electric lock unlocking / door opening / closing according to the verification result of the authentication unit 131. The entry / exit history data such as the verification result, electric lock unlocking / door opening / closing operation result, etc. is stored in the storage unit 110.

  The storage unit 110 has a function of storing pre-registration information input by the pre-registration unit 1121, body temperature measured by the authentication unit 131, and entry / exit history data stored by the electric lock / door control unit 132. .

  The air conditioning control unit 1201 has a function of performing air conditioning control using the information stored in the storage unit 110 as a parameter.

  FIG. 3 is a process flowchart of the air conditioning control support device according to the embodiment of the present invention.

  When the certifier performs biometric verification at the time of entering and leaving the room (S501), it is confirmed whether the validity period of the passage authority of the certifier is valid (S502). If the passage authority is valid (S502 “Yes”), it is confirmed whether the passage area is a permitted area (S503). If the passage area is a permission area (S503 “Yes”), door unlock control processing is performed (S504, S505). History data (133 in FIG. 2) associated with this verification operation is stored in the entry / exit management server 112 as entry / exit history data. The facility management server 111 refers to the history data 133 and confirms whether the cumulative number of people in the room exceeds a certain number or whether there is a high fever (S506, S507). When the cumulative number of people in the room exceeds a certain number (S506 “Yes”), individual parameter control is performed (S508). The individual parameter control when the cumulative number of people in the room exceeds a certain number of people, for example, is to lower the air conditioning target temperature in the air conditioning area than usual. It is also possible to incorporate other controls that enhance the arousal effect.

  On the other hand, when there is a high fever (S507 “Yes”), individual parameter control is performed (S508). The individual parameter control in this case will be described next with reference to FIGS. 4A and 4B.

  When the cumulative number of people in the room does not exceed a certain number (S506 “No”) or when there is no high fever (S507 “No”), air conditioning control is performed according to a normal schedule (S509).

  4A and 4B show an example of biometric history data and air conditioning control. When the building user enters the room, if biometric verification such as finger veins, fingerprints, and ears is performed, personal information such as personal ID, room area, air-conditioning area, and normal body temperature is recalled as shown in FIG. 4A. The entry time and body temperature at the time of authentication are newly written. From this history data, the cumulative number of people in the room and the presence or absence of high fever are determined. As for the presence or absence of a high fever, it is determined that there is a high fever when there is a certifier who has a positive difference between the normal body temperature and the body temperature during authentication.

  In the case of the data in FIG. 4A, the room occupant whose personal ID is 19 is determined to be a high fever of 38 degrees by authentication. Therefore, the parameter control of the air conditioning equipment is started for the entire air conditioning areas A to H shown in FIG. 4B.

  The parameter control here refers to air-conditioning control using the cumulative number of people in the room and the presence or absence of high heat as parameters. If there is a person with high fever, it is judged that there is a suspicion of influenza infection. For example, the temperature is set to around the temperature and humidity (eg, relative temperature 20 ° C, relative humidity 50%), which is said to deactivate the influenza virus. Change the control method to change the value, or add weak chlorine-based disinfectant to the humidifier, adjust the amount of disinfectant, increase the number of ventilation.

  In the example of FIGS. 4A and 4B, the room occupant whose personal ID is 64 is also determined to be a high fever of 38 degrees by authentication. Therefore, the parameter control of the air conditioning equipment is started also for the air conditioning areas I to J shown in FIG. 4B.

  Economic losses associated with the spread of influenza and other infectious diseases are enormous, and places where people gather, such as office buildings, contribute to the spread of infection. For occupants in a building, an air environment that is constantly exposed is extremely important for improving health promotion. According to the present invention, air-conditioning control according to the actual condition of the occupant can be performed, which is useful for measures against influenza infection and improvement of air-conditioning control accuracy.
