  In recent years, the traffic of people on a global scale has become active, and passengers suffering from diseases with infectious fever have been detected at an early stage in transportation such as airplanes, ships, and railways that are used as mass transit means for passengers. Social security is required to take necessary security measures.

However, the techniques disclosed in Patent Documents 1 and 2 do not meet this requirement.
The seating monitoring system described in Patent Document 1 includes a body temperature detection sensor. This body temperature detection sensor identifies whether a load load body on a seat is a person or an object. It does not measure body temperature. Therefore, crew members and the like cannot grasp the passenger's body temperature using this system. In addition, the seat device described in Patent Document 2 manages and controls the state of facilities related to safety rules such as a seat back, a legrest, and a seat belt, and manages the body temperature of the passenger. It is not a thing.

  Among them, aircraft and ships are often used for long distances and long-time movements, and passengers are restrained in closed spaces such as cabins. For this reason, it is conceivable that the passenger's physical condition changes during movement, but it is difficult for the crew to notice the passenger's physical condition change. On the other hand, non-contact body temperature measurement using infrared rays is suitable for measuring body temperature without causing the passenger to feel stress. However, since the infrared detectors that are usually used are large and large, the installation location is limited, and the body temperature of people coming and going at airports and ports, and at customs gates is often measured. This method slows the discovery and may spread the infection if, for example, there is a passenger with an infection that needs to be isolated.

  As described above, the case of transportation such as an aircraft or a ship has been described as an example. However, medical institutions such as hospitals have the same problem. That is, when a plurality of patients are hospitalized, there is a need for a system that allows doctors and nurses to quickly grasp changes in body temperature of individual patients and take prompt actions.

  The present invention has been made in order to solve the above-described problems. For example, the body temperature of a plurality of persons can be detected by a simple method in a transportation system such as an aircraft or a ship, and an abnormality can be detected early.

[First Embodiment]
Hereinafter, the seat apparatus of 1st Embodiment of this invention is demonstrated using FIGS. 1-3. The seat device of this embodiment is an example of a seat device used for an aircraft.
In FIG. 1 to FIG. 3, in order to make each component easy to see, depending on the component, the dimensional scale may be changed.

  As shown in FIG. 1, the seat device 1 of the present embodiment includes a plurality of seats 2, an infrared sensor 3 (infrared detector) that detects the body temperature of a passenger M <b> 1 (detected person) seated in each seat 2, and It has. The infrared sensor 3 is embedded in the rear surface 4a of the backrest 4 of each seat 2, and is installed at a height substantially corresponding to the position of the face of the passenger M1 seated on the rear seat. However, the position of the infrared sensor 3 can be automatically finely adjusted, and the visual field detected by the infrared sensor 3 can be finely adjusted. In FIG. 1, only two seats 2 arranged in the front-rear direction are illustrated, but actually, a large number of seats are arranged in the front-rear direction and the left-right direction.

  The infrared sensor 3 is made of a material having a large dielectric constant, such as a ferroelectric such as lead zirconate titanate (PZT), a semiconductor such as lithium niobate, or a ferroelectric resin such as polyvinylidene fluoride. It is a pyroelectric infrared sensor utilizing a phenomenon that generates electric charges when a temperature change of a material occurs, that is, a so-called pyroelectric effect. When the infrared sensor 3 receives an infrared ray emitted from the human body of the passenger M1, polarization occurs in the above material to generate a charge corresponding to the amount of infrared ray, and the body temperature is measured by detecting the charge amount.

  The infrared sensor 3 of the present embodiment is not a type that measures the body temperature of one point of the human body of the passenger M1, but is a type that can capture the body temperature distribution of the face as an infrared image. The detection wavelength range of the infrared sensor 3 is desirably 8 to 12 μm. The detection wavelength range of 8 to 12 μm of the infrared sensor 3 corresponds to about 34 to 42 ° C. in the detection temperature range. Therefore, an infrared sensor having this detection wavelength range is suitable for measuring human body temperature.

  As shown in FIG. 2, the seat device 1 according to the present embodiment has a system configuration other than the seat 2 and the infrared sensor 3 described above. Unit 9 and a plurality of portable display units 10. The input interface 5 receives output signals from the plurality of infrared sensors 3. The communication unit 6 performs A / D conversion on an output signal from the infrared sensor 3 input via the input interface 5.

  The parameter setting unit 8 sets various parameters necessary for the crew member to grasp the body temperature of the specific passenger M1. The parameters include, for example, the position of the seat (seat number), the passenger's name, age, sex, display body temperature, measurement sensitivity and resolution, body temperature threshold, position of the infrared sensor 3, and the like. Based on the output signal from the infrared sensor 3 and the parameters set by the parameter setting unit 8, the control unit 7 generates a control signal for controlling the display unit 9 and the portable display unit 10 to be described later. 9 and the portable display unit 10.

  The display unit 9 is configured by a display installed on a wall surface of a cabin crew room, a cockpit, or the like, for example. The display unit 9 displays various types of information including information on the body temperature of the passenger M1 and the passenger M1 based on the control signal from the control unit 7. Examples of the passenger-related information include a seat position (seat number), a passenger name, a thermo image of a face (infrared image), and the like. In addition to the above information, the display unit displays a seat layout, a body temperature display cursor, and the like.

  The portable display unit 10 is configured by a display mounted on an arbitrary portable device carried by, for example, a flight attendant. Therefore, the control signal from the control unit 7 is transmitted to the portable display unit 10 by wireless communication. Similar to the display unit 9, the portable display unit 10 displays various types of information including information about the body temperature of the passenger M <b> 1 and the passenger M <b> 1 based on the control signal from the control unit 7. The display items on the mobile display unit 10 may be the same as or different from the display items on the display unit 9. Since the portable display unit 10 is generally smaller than the display unit 9, the portable display unit 10 displays only the seat position (seat number), the passenger's name, and the passenger's body temperature among the display items of the display unit 9. The structure to display may be sufficient.

  FIG. 3 is a diagram illustrating a display example of the display unit 9. In this example, the display unit 9 has two screens, the left screen is a seat layout display screen 9a showing the layout of the seats of the entire cabin, and the right screen is a specific passenger M1 selected by the crew. It is the individual information display screen 9b which shows body temperature and various information. In FIG. 3, information is already displayed on both the seat layout display screen 9a and the individual information display screen 9b. The seat layout display screen 9a and the individual information display screen 9b may be configured to be spatially separated as in this example, or the entire display unit 9 may be switched to one of the screens in time.

  In this example, for example, it is assumed that “37.0 ° C.” is set as the body temperature threshold in the parameter setting unit 8. In this case, the control unit 7 extracts only the passenger M1 having a body temperature of 37.0 ° C. or more from the plurality of passengers M1 whose body temperature is detected by the infrared sensor 3 of each seat 2, and sends a control signal to the display unit 9. Send. Then, on the seat layout display screen 9a of the display unit 9, the lamp indicating the seat of the passenger M1 having a body temperature of 37.0 ° C. or higher is turned on, and the lamp indicating the seat of the passenger M1 having a body temperature of less than 37.0 ° C. is Turns off. For example, assume that the lamps of seats with seat numbers 15-K and 20-C are lit. The crew member grasps that the body temperature of the two passengers M1 seated in the seat with the seat number 15-K and the seat with the seat 20-C is 37.0 ° C. or more by looking at the seat layout display screen 9a. be able to.

  Next, when the crew member wants to particularly monitor a passenger whose seat number is 15-K among the passengers M1 whose body temperature is 37.0 ° C. or higher, the parameter setting unit 8 sets the parameter seat number to “15- K ”is set. At this time, a thermo image S (infrared image) of the face of the passenger M1 is displayed on the individual information display screen 9b, and the seat number and body temperature are indicated as “seat No .: 15-K, body temperature: 37.2 ° C.”. Is displayed. If the crew member sees the individual information display screen 9b, it can grasp that the body temperature of the passenger M1 whose seat number is 15-K is actually 37.2 ° C. At the same time, since the thermo image S of the face is displayed, the crew member, for example, the body movement such as whether the passenger M1 frequently moves or stays still, or only part of the face generates heat. It is possible to grasp the state of heat generation such as whether or not the neck and hand are generating heat in addition to the face.

  As described above, according to the seat device 1 of the present embodiment, the crew member can sequentially grasp the body temperature of the passenger M1 and detailed information about the passenger M1 for each seat by looking at the display unit 9, so Passengers and their situation can be grasped early. Furthermore, since the seat device 1 of the present embodiment includes the portable display unit 10, the passenger who has generated heat and the situation thereof can be grasped even when the crew member is outside the crew room, that is, away from the display unit 9. Can do. This allows the crew to take the necessary action as soon as possible and contain the risk of infection with fever at the water's edge. Thus, the seat device 1 of the present embodiment can contribute to safe and secure passenger transportation.

  Further, the pyroelectric infrared sensor 3 can detect infrared rays emitted from the human body in a non-contact manner, and the passenger M1 is sitting on the seat 2 and the body temperature is measured sequentially. Therefore, the passenger M1 hardly feels the sense that the body temperature is measured, and hardly feels stress. Further, since the pyroelectric infrared sensor 3 is small and does not require cooling, it can be easily incorporated into the backrest 4 of the seat 2 and a simple device can be configured.

[Second Embodiment]
Hereinafter, the seat apparatus of 2nd Embodiment of this invention is demonstrated using FIG.

However, depending on the class of aircraft seat, even if an infrared sensor is installed on the back of the seat back, the infrared sensor may not be able to detect infrared rays emitted from passengers in the rear seat. In this embodiment, an example corresponding to such a case is given.

  The seat device 11 of the present embodiment is assumed to be used in an aircraft business class or first class. As shown in FIG. 4, the seat device 11 of the present embodiment is an independent compartment type seat in which the individual seats 12 are accommodated in a capsule-like structure 13. The infrared sensor 14 is embedded in the rear surface 13a of the front seat structure 13, and is installed at a height substantially corresponding to the position of the face of the passenger (detected person) seated in the rear seat. For the front row seat, the infrared sensor 14 is embedded in the front wall surface 15. Even in this configuration, the infrared sensor 14 can capture a thermo image (infrared image) of the passenger's face. Other system configurations are the same as those in the first embodiment.

  Also in this embodiment, the same effect as 1st Embodiment that the passenger's body temperature can be detected with a simple method and an abnormality such as an infection with fever can be detected at an early stage can be provided.

[Third Embodiment]

Unlike the first and second embodiments, the present embodiment is an example of a human body support device used in a hospital.

  As shown in FIG. 5, the human body support device 16 of this embodiment includes a bed 17 (human body support) and an infrared sensor 18. The human body support device 16 of the present embodiment is assumed to be used in, for example, an inpatient ward of a hospital, and only one bed 17 is shown in FIG. 5, but a plurality of beds are arranged in a hospital room. The infrared sensor 18 is installed on the ceiling 19 of the hospital room facing the human body support surface 17 a of the bed 17. The infrared sensor 18 is installed on the ceiling 19 of the hospital room at a position substantially above the face when the patient M2 (detected person) sleeps on the bed 17. One infrared sensor 18 is installed for each bed 17.

  Other system configurations are the same as those in the first embodiment. For example, each bed 17 is assigned a number for identifying the bed 17 such as 201-A, 201-B,..., 205-C, 205-D,. ing. The parameter setting section, control section, display section, etc. are installed in the nurse station, and doctors and nurses carry the portable display section. Doctors and nurses can instantly grasp the patient's body temperature for each bed 17 in each hospital room by looking at the display unit or portable display unit of the nurse station. Further, the doctor or nurse can select a bed number such as 201-A, for example, to see a thermo image of the specific patient M2 and grasp a detailed condition such as the fever status of the patient M2.

  Conventionally, when grasping a patient's body temperature, a method in which a nurse patrols a hospital room every predetermined time and asks the patient to perform a temperature measurement has been common. Accordingly, even if the body temperature at the time when the nurse patrols can be grasped, if the body temperature changes before the next patrol, the body temperature change may not be grasped. In that respect, according to the human body support device 16 of the present embodiment, the body temperature of the patient M2 can be grasped sequentially, and the detailed situation of the patient M2 to be particularly careful can be known, so that necessary measures can be taken immediately. Can do. Further, in the human body support device 16 of the present embodiment, it is not necessary to use a thermometer, and the body temperature is measured by a non-contact method using the infrared sensor 18, so that secondary infection is not caused without imposing a burden on the patient M2. Occurrence can be suppressed.
