The body temperature calculation unit 53 determines the position of a part (hereinafter referred to as a body temperature measurement part) that is predetermined as a body temperature measurement location on the body of the pet 2 based on the position of the pet 2 detected by the posture detection unit 51 and its posture. The body temperature of the body temperature measurement part is calculated using the output of the temperature sensor 10. The posture evaluation system 1 may have a configuration in which the temperature sensor 10 and the body temperature calculation unit 53 are further provided in the configuration of the first embodiment.

  A plurality of temperature sensors 10 are arranged in the bed 3 so as to extend in the horizontal direction. These temperature sensors 10 are arranged in a uniform manner in a matrix. When the pet 2 gets on the bed 3, the temperature sensor 10 measures the temperature of the part where the pet 2 is in contact with the bed 3, and sends the measured value information to the body temperature calculation unit 53. The installation position of the temperature sensor 10 is not limited to the inside of the bed 3 and may be in the vicinity of the bed 3.

  The body temperature calculation unit 53 includes a microprocessor and a flash memory in which position coordinate information of the temperature sensor 10 is stored. The body temperature calculation unit 53 and the posture detection unit 51 may share a microprocessor. The microprocessor calculates the body temperature of the body temperature measurement portion of the pet 2 using the output of the temperature sensor 10. By measuring a body temperature measurement location in advance and measuring the body temperature at that location, it is possible to eliminate the influence of the body temperature variation associated with the change in the measurement location, and to detect the body temperature variation of the pet 2 with high accuracy. In the flash memory, the body temperature calculated by the microprocessor is sequentially stored in association with the calculated date and time information, and the flash memory holds the body temperature history of the pet 2. Details of processing contents from body temperature calculation to body temperature history storage in the body temperature calculation unit 53 will be described later.

  In addition, the microprocessor of the body temperature calculation unit 53 refers to the body temperature history in the flash memory of the body temperature calculation unit 53, and calculates the average value of body temperature over a predetermined past period, that is, normal heat. Furthermore, the microprocessor uses the primary storage memory to compare the above normal heat with the current body temperature and obtain the difference between them. When the difference is equal to or greater than a predetermined threshold, the microprocessor notifies the display unit 6 as an abnormal situation.

  The display unit 6 receives the notification from the body temperature calculation unit 53 and displays that the body temperature of the pet 2 is abnormal. The display unit 6 may display the current body temperature of the pet 2. The display showing the abnormal body temperature can inform the owner of the poor physical condition of the pet 2.

  In addition, the display part 6 may be provided in portable terminals, such as a mobile phone which an owner can carry. In this case, the body temperature calculation unit 53 transmits a mail using a predetermined mail address of the portable terminal as a transmission destination using a communication unit (not shown) configured by an interface connectable to the Internet. This e-mail includes text notifying the abnormality of the body temperature of the pet 2. The content of the mail is displayed on the display unit 6 of the portable terminal. Therefore, even when the owner is out, the owner can be notified of the poor physical condition of the pet 2.

  FIG. 9 shows the processing contents by the microprocessor of the body temperature calculation unit 53. First, the position coordinates of the body temperature measurement portion of the pet 2 are calculated based on posture data created by the posture detection unit 51 (S1). Next, the position coordinate information of the temperature sensor 10 stored in the flash memory is referred to, and among all the temperature sensors 10, a plurality of temperature sensors 10 whose position coordinates are in the vicinity of the position coordinates of the body temperature measurement part are selected. (S2). Based on the output of the selected temperature sensor 10, the body temperature of the body temperature measurement part is calculated using a two-dimensional interpolation method, and the calculated body temperature is estimated as the body temperature of the pet 2 (S3). The body temperature calculation process using the two-dimensional interpolation method will be described later. The estimated body temperature is sequentially stored in the flash memory, and the body temperature history is stored in the flash memory (S4).

  Next, a body temperature calculation process using a two-dimensional interpolation method, particularly a linear interpolation method, by the body temperature calculation unit 53 will be described with reference to FIG. This figure is a plan view of the pet 2 (shown by a broken line) on the bed 3 when viewed from above, the body temperature measurement portion 23 of the pet 2 is shown by a dotted circle, and the pressure sensor 4 is not shown. . Here, the symbols of the four temperature sensors 10 that take the coordinates in the vicinity of the position coordinates of the body temperature measurement portion 23 are 10A, 10B, 10C, 10D (hereinafter referred to as 10A, etc.).

  The body temperature calculation unit 53 calculates the temperature at the position coordinate of the body temperature measurement portion 23 by linearly combining the temperature (measured value) measured by the temperature sensor 10A or the like according to the position coordinate of the temperature sensor 10A or the like. The linear combination in the linear interpolation is performed using a known technique. As the two-dimensional interpolation method, in addition to the linear interpolation method, a cubic interpolation method or a cubic spline interpolation method may be used.

  In the present embodiment, since the body temperature of the pet 2 can be measured simply by the pet 2 getting on the bed 3, the measurement is simplified and the physical condition management of the pet 2 is facilitated. In addition, it is possible to prevent the pet 2 from being stressed during measurement. In addition, the body temperature calculation unit 53 stores the body temperature history of the pet 2, calculates the normal heat of the pet 2 based on the body temperature history, and compares the normal heat of the pet 2 with the current body temperature. Body temperature fluctuations can be detected with high accuracy.

  Further, even when the position coordinates of the body temperature measurement portion 23 of the pet 2 are between the position coordinates of the temperature sensor 10, the body temperature of the body temperature measurement portion 23 is calculated using the two-dimensional interpolation method. The body temperature of the portion 23 can be estimated with high accuracy. Further, the number of temperature sensors 10 can be reduced, and the manufacturing cost can be reduced.

The temperature sensor 11 is installed on the side wall or ceiling in the pet shed 31. The air conditioning unit 12 includes a heater, an air conditioner, and the like.

  Furthermore, in the posture evaluation system 1, the lighting apparatus 14 that irradiates light on the bed surface 3a of the bed 3 and the sleep state estimation unit 54 are able to sleep the pet 2 during a predetermined time period, as compared with the configuration of the second embodiment.

The posture detection time interval may be set in advance when the arithmetic device 5 is manufactured, or may be set by the owner as a user using an operation unit (not shown). The posture comparison unit 52 compares the current posture data with the posture data immediately before it to create comparison information, and sends the comparison information to the sleep state estimation unit 54.

  The sleep state estimation unit 54 is configured by a microprocessor. This microprocessor determines whether the pet 2 is sleeping based on the comparison information sent from the posture comparison unit 52, and detects the amount of body movement of the pet 2 during sleep when it is determined that the pet 2 is sleeping. Whether or not the user is sleeping is determined based on whether or not a time period in which posture data does not substantially change exceeds a predetermined time.

  Further, the microprocessor of the sleep state estimation unit 54 estimates the sleep depth of the pet 2 based on the transition of the body movement amount of the pet 2. Specifically, when the time when the amount of body movement is equal to or greater than a threshold value exceeds a predetermined time, it is estimated that there has been a wake-up action, turning over, or awakening in the middle, and the sleep of the pet 2 is estimated to be shallow. Instead of or in addition to sleep depth, sleep time may be estimated. The microprocessor sends a signal indicating the estimation result, for example, a signal indicating that the sleep is shallow, to the air conditioning control unit 13 and the lighting control unit 15. The sleep state estimation unit 54 may share a microprocessor with the posture comparison unit 52.

The air conditioning unit 12 operates based on a control signal from the air conditioning control unit 13 and adjusts the temperature of the space where the pet 2 above the bed 3 is located.

  The air conditioning control unit 13 includes a microprocessor that sends a control signal to the air conditioning unit 12 and a flash memory that stores an ideal temperature comfortable for the pet 2. When the microprocessor receives a signal indicating that the sleep of the pet 2 is shallow from the sleep state estimation unit 54, the microprocessor compares the measured value by the temperature sensor 11 with the ideal temperature with reference to the flash memory, and detects the difference between them. To do. Then, the microprocessor sends a control signal instructing cancellation of this difference to the air conditioning unit 12. The air conditioning unit 12 is driven according to this control signal, and the temperature around the pet 2 becomes the ideal temperature.

  In addition, the attitude | position detection part 51 is comprised with the temperature sensor, and this temperature sensor may be embed | buried under the bed 3. FIG. In this case, even if the air conditioning unit 12 is operated, since the temperature sensor is inside the bed 3, the temperature sensor is hardly affected by the air conditioning unit 12, and the accuracy of posture detection can be prevented from being lowered.

  The lighting fixture 14 includes a light source and a lighting control circuit that turns on, turns off, or dimmes the light source based on a control signal from the lighting control unit 15. The luminaire 14 is a fluorescent lamp luminaire provided with a diffusion panel on the wall surface or ceiling surface in the pet shed 31, a stand-type luminaire provided in the pet shed 31 or in the room, or a ceiling provided in the room. Consists of direct-mounted ceiling light fixtures.

  The illumination control unit 15 includes a timer that counts the current time and a microprocessor. When the microprocessor receives a signal indicating that the sleep of the pet 2 is shallow from the sleep state estimation unit 54, the microprocessor measures the reception time with a timer. Then, when the reception time is within a preset time zone, the microprocessor sends a control signal instructing lighting of the light source to the luminaire 14. The time zone is set by the owner using an operation unit (not shown). As the time zone to be set, for example, a morning time zone in which sleep is shallow is assumed.

  In this embodiment, since the body movement during sleep of the pet 2 is detected based on the posture change of the pet 2 from the sleep state estimation unit 54, the sleep state that appears during the sleep of the pet 2 and indicates the quality of sleep, It is possible to detect body movement such as movement or movement caused by mid-wakening. For this reason, the quality of sleep of the pet 2 can be detected.

  In addition, when the pet 2 is lightly sleep, the air-conditioning control unit 13 adjusts the temperature to an ideal temperature comfortable for the pet 2, so that the comfort of the pet 2 due to the cold and cold is eliminated and the pet 2 sleeps deeply. It can be.

  In addition, when the pet 2 is lightly sleep in the set time zone, the illumination light of the lighting device 14 is irradiated to the pet 2, so that the pet 2 can be awakened during the set time zone, and the pet 2 gets up. Can be encouraged. For this reason, it becomes possible to maintain the health of the pet 2 by making the life rhythm of the pet 2 regular. As a result, the pet 2 comes to sleep at night, and it is possible to prevent the owner and the neighborhood from being disturbed by screaming at night. In this embodiment, the same effect as any of the first to third embodiments can be obtained.

  The present invention is not limited to the configurations of the first to fourth embodiments, and various modifications can be made according to the purpose of use. For example, the pressure sensor 4 may be installed near the center of the bed 3 where the pet 2 often rides at a higher density than the end of the bed 3. Further, the posture data stored in the flash memory of the posture comparison unit 52 may be only data for one posture detection. Further, the speaker may notify the owner of the comparison information output from the posture comparison unit 52 with a sound instead of the display unit 6.
