On the other hand, the air curtain device control unit 72 of the processing server 7 outputs an operation command signal to the air curtain device 5 when the entry / exit management system 3 determines that the room can be entered. The air curtain device 5 starts blowing out air in response to an operation command signal (step S103 in FIG. 3).

The information collecting unit 70 of the processing server 7 acquires at least one of today's pollen scattering information and today's PM2.5 scattering information at the location of facility 1 from an external system (FIG. 3, step S104).

The spray device control unit 73 of the processing server 7 determines that the entry / exit management system 3 can enter the room, and at least of the pollen scattering information and the PM2.5 scattering information acquired from the external system via the information collecting unit 70. When one of them is scattered (YES in step S105 of FIG. 3), an injection command signal is output to the spray device 6. The spraying device 6 sprays the particle removing agent in the form of mist in response to the jet command signal (step S106 of FIG. 3).

The spray device control unit 73 determines that the entry / exit management system 3 can enter the room, and today's pollen scattering information and today's PM2.5 scattering information at the location of the facility 1 acquired from the external system are not scattered. If (NO in step S104), the injection command signal is not output.

FIG. 4 is a view of the doorway 4 as viewed from the inside of the facility 1. By the processing of steps S102 to S105, the door of the entrance / exit 4 is opened, and the air in which the particle removing agent is diffused in a mist form is blown out from the air curtain device 5. The particle removing agent (static electricity removing agent) can easily remove pollen and PM2.5 adhering to the hair and clothes of the occupant by removing the static electricity of the hair and clothes of the occupant. In this way, pollen and PM2.5 adhering to the hair and clothes of the occupants can be blown off.
In this embodiment, the air curtain device 5 takes in the air in the facility 1 and removes dust such as pollen by a filter to purify the air curtain device 5, but it is essential to provide the air curtain device with a filter function in the present invention. It is not a component of.

When the automatic door device 40 detects the passage of an occupant (YES in step S107 of FIG. 3), the automatic door control unit 71 outputs an automatic door closing command signal to the automatic door device 40. The automatic door device 40 closes the door of the doorway 4 in response to the automatic door closing command signal (step S108 in FIG. 3).

The air curtain device control unit 72 outputs a stop command signal to the air curtain device 5 when the automatic door device 40 detects the passage of an occupant. The air curtain device 5 stops the air blowout in response to the stop command signal (step S109 in FIG. 3).

When the automatic door device 40 detects the passage of an occupant, the spray device control unit 73 outputs a stop command signal to the spray device 6. The spraying device 6 stops the injection of the particle removing agent in response to the stop command signal (step S110 in FIG. 3).

In this way, in this embodiment, pollen and particulate matter such as PM2.5 adhering to the body and clothing of the occupant can be removed more effectively than the conventional air curtain.

[Second Example]
If the amount of pollen scattering information and the amount of PM2.5 scattering information can be collected from an external system, the amount of the particle removing agent may be adjusted. Also in this embodiment, since the configuration of the particulate matter removal system is the same as that in the first embodiment, the reference numerals of FIGS. 1 and 2 will be used for description.

FIG. 5 is a flowchart illustrating the operation of the particulate matter removal system of this embodiment. The processing of steps S100 to S105 of FIG. 5 is as described in the first embodiment.

When the entry / exit management system 3 determines that the room can be entered and the amount of pollen and PM2.5 scattered is less than the threshold value (YES in step S111 in FIG. 5), the spray device control unit 73 of the present embodiment sets the spray device 6. Outputs a small amount injection command signal. The spraying device 6 sprays a predetermined amount (first injection amount) of the particle removing agent in the form of mist in response to the small amount injection command signal (FIG. 5, step S112).

When the information collecting unit 70 collects only the pollen scattering information, the process of step S112 may be performed when the pollen scattering amount is less than the threshold value, and when the information collecting unit 70 collects only the PM2.5 scattering information, When the amount of PM2.5 scattered is less than the threshold value, the process of step S112 may be performed.
In this embodiment, for example, the ^{amount of pollen per cm 2} is 30 per day as the threshold value for the amount of pollen scattered. Further, for example, ^{a concentration of 35 μg / m 3} per day is set as a threshold value for the amount of PM2.5 scattered.

Further, when the spray device control unit 73 determines that the room entry / exit management system 3 can enter the room and at least one of the pollen scattering amount and the PM2.5 scattering amount is larger than the corresponding threshold value (NO in step S111). A large amount of injection command signal is output to the spray device 6. The spraying device 6 atomizes a predetermined amount (second injection amount) of the particle removing agent so as to be larger than that at the time of the small amount injection in step S112 in response to the large amount injection command signal (FIG. 6). 5 steps S113).

Similar to the first embodiment, the spray device control unit 73 does not output the injection command signal when the pollen scattering information and the PM2.5 scattering information are not scattered.
The processing of steps S107 to S110 of FIG. 5 is as described in the first embodiment.

Thus, in this embodiment, the injection amount of the particle removing agent can be adjusted according to the amount of scattered pollen and PM2.5.
In the first and second embodiments, it is sufficient if the entry of a person into the facility 1 can be detected, and authentication and identification of an individual are not essential requirements. Therefore, for example, a person using infrared rays, ultrasonic waves, visible light, or the like is used. A motion sensor that detects the presence of a person may be installed at the entrance / exit 4 to detect the entry / exit of a person.

[Third Example]

When the entry / exit management system 3 determines that entry is possible (YES in step S101 of FIG. 7), the automatic door control unit 71 of the processing server 7 automatically sets the place where the person permitted by the entry / exit management system 3 intends to enter the room. An automatic door open command signal is output to the door device 40. The automatic door device 40 opens the door of the doorway 4 in response to the automatic door open command signal (step S102a in FIG. 7).

When the entry / exit management system 3 determines that the entry / exit management system 3 can enter the room, the air curtain device control unit 72 of the processing server 7 sends an operation command signal to the air curtain device 5 at the place where the person permitted by the entry / exit management system 3 intends to enter the room. Is output. The air curtain device 5 starts blowing out air in response to an operation command signal (step S103a in FIG. 7).
The processes of steps S104 and S105 in FIG. 7 are as described in the first embodiment.

In the spray device control unit 73 of the processing server 7, the entry / exit management system 3 determines that the entry is from outside the facility (YES in step S114 of FIG. 7), and the amount of pollen and PM2.5 scattered is a threshold value, respectively. When the number is less (YES in step S111 in FIG. 7), a small amount injection command signal is output to the spray device 6 provided at the entrance / exit 4 of the facility 1. The spraying device 6 sprays a predetermined amount (first injection amount) of the particle removing agent in the form of mist in response to the small amount injection command signal (FIG. 7 step S112a).

In addition, the spray device control unit 73 determines that the person entering the room is a person entering the room from outside the facility by the entry / exit management system 3 (YES in step S114), and at least one of the amount of pollen scattered and the amount of PM2.5 scattered. Is greater than the corresponding threshold value (NO in step S111), a large amount of injection command signal is output to the spray device 6 provided at the entrance / exit 4 of the facility 1. In response to the large-volume injection command signal, the spraying device 6 atomizes a predetermined amount (second injection amount) of the particle removing agent so that the amount is larger than that at the time of small-quantity injection in step S112a (FIG. 6). 7 steps S113a).

Further, when the room entry / exit management system 3 determines that the person entering the room is not a person entering the room from outside the facility but a person entering the room 10 by moving inside the facility 1 (step S114). NO), a small amount injection command signal is output to the spray device 6 at the place where the person permitted by the entry / exit management system 3 intends to enter the room. The spraying device 6 ejects a predetermined amount of the particle removing agent in the form of mist in response to the small amount injection command signal (step S112a).

When the automatic door device 40 detects the passage of an entrant (YES in step S107a in FIG. 7), the automatic door control unit 71 outputs an automatic door closing command signal to the automatic door device 40 at the place where the occupant has passed. .. The automatic door device 40 closes the door of the doorway 4 in response to the automatic door closing command signal (step S108a in FIG. 7).

When the automatic door device 40 detects the passage of the occupant, the air curtain device control unit 72 outputs a stop command signal to the air curtain device 5 at the place where the occupant has passed. The air curtain device 5 stops the air blowout in response to the stop command signal (step S109a in FIG. 7).

When the automatic door device 40 detects the passage of the occupant, the spray device control unit 73 outputs a stop command signal to the spray device 6 at the place where the occupant has passed. The spraying device 6 stops the injection of the particle removing agent in response to the stop command signal (step S110a in FIG. 7).

Thus, in this embodiment, the amount of the particle removing agent sprayed is reduced when the room is not entered from outside the facility.
In this embodiment, it is premised that the entry / exit management system 3 can identify an individual and can grasp the movement of an individual in the facility 1, but it goes without saying that such a system has been put into practical use. stomach.
