Description

  The present invention relates to a pedometer that measures the number of steps during walking, and particularly to a pedometer that has a function of providing information for preventing heat stroke during walking, mainly in a season when the temperature is relatively high. It is related.

  Due to the recent increase in health consciousness, exercises that can be easily tackled regardless of age, such as jogging and walking, are actively performed. Such exercise can be done easily, but if it is not performed properly in consideration of the environment, heat stroke may occur. Heat stroke is a general term for symptoms that occur mainly due to high-temperature and high-humidity environments. It is broadly divided into heat syncope, heat fatigue, heat convulsions, and heat stroke. is there.

  A person who performs walking often carries a pedometer to grasp the amount of exercise and enhance motivation. For example, as disclosed in Patent Document 1, the distance to the ground, that is, the number of steps and calorie consumption are calculated. Pedometers with a display function are commercially available. In addition to this, Patent Document 2 discloses a device that integrates a mobile phone and a pedometer and can visualize information related to the amount of exercise on a display.

  Those equipped with such options are useful for the prevention of heat stroke to some extent because the amount of exercise can be grasped as described above. However, there is nothing that can provide information directly related to the prevention of heat stroke, and if there is a pedometer with such a function, it will contribute to the prevention of heat stroke and thus the health of the user. Are considered to be extremely large.

  Therefore, the subject of this invention is providing the pedometer which can display the information which leads to heat stroke prevention in view of the above backgrounds.

  Various thermal indices for evaluating high temperature and humidity have been proposed for the purpose of preventing heat stroke, but the present invention has been made as a result of studying the provision of a function for measuring and displaying a thermal index on a pedometer. It is a thing.

  That is, the present invention is a pedometer comprising a temperature sensor and a humidity sensor, and the pedometer includes an arithmetic device that calculates a thermal index from measured values of temperature and humidity, and a calculated numerical value and information based thereon. It has the device which displays.

  Further, the present invention is characterized by using WBGT (Wet Valve Globe Temperature) as a thermal index, but other thermal indices can also be used.

WBGT was proposed in the United States in the 1950s, and is calculated by the following equation based on the dry bulb temperature, wet bulb temperature, and black bulb temperature, and it is said that the hot and humid environment can be accurately evaluated.
(1) When there is solar radiation outdoors WBGT = (wet bulb temperature) × 0.7 + (black bulb temperature) × 0.2 + (dry bulb temperature) × 0.1
(2) When there is no solar radiation indoors WBGT = (wet bulb temperature) x 0.7 + (black bulb temperature) x 0.3

  Since the pedometer of the present invention includes the temperature sensor, the humidity sensor, the calculation device, and the display device as described above, the momentum can be grasped and the temperature index can be known in real time when used during walking. It is possible to accurately prevent heat stroke. Moreover, since the user does not always look at the display device during walking, an alarm can be issued by voice when the thermal index exceeds a certain value.

  Note that some pedometers use a pendulum sensor or an acceleration sensor as a pedometer, but any of the present invention can be used, and the type of temperature sensor or humidity sensor used is not limited. Of course.

  Next, embodiments of the present invention will be described with reference to specific drawings.

  FIG. 1 is a perspective view showing an example of a pedometer according to the present invention. In FIG. 1, 1 is a display device, 2 is a step count display section, 3 is a thermal index display section, 4 is a switch section, 5 is a sticker attaching section, and 6 is an openable cover.

  The display unit 1 includes a temperature sensor, a humidity sensor, and an arithmetic device for measuring dry bulb temperature, wet bulb temperature, and black bulb temperature, and is configured to display a thermal index. The sticker sticking part is not an essential element of the pedometer of the present invention, but a table of the thermal index value and the degree of risk is stuck on the back side surface of the openable cover 6, that is, the sticker sticking part 5, The convenience can be aimed at.

  In addition, the display unit 1 or the openable cover 6 is appropriately provided with a speaker, a buzzer, a vibrator, etc., so that when the thermal index reaches a dangerous value, an alarm is given to the user using sound or vibration. Can be emitted.

  FIG. 2 is a view showing an example in which a clip is provided on the pedometer according to the present invention, FIG. 2 (a) is a side view, and FIG. 2 (b) is a rear view. In FIG. 2, 7 is a clip. Using the clip 7, the user can wear the pedometer of the present invention on a part of the body via a belt or the like.

  FIG. 3 shows a procedure for outputting the measured values of the temperature sensor 9 and the humidity sensor 10 to the computing device 11 and outputting the thermal index calculated by the computing device 11 to the display device 12 in the pedometer 8a according to the present invention. It is a block diagram. In the pedometer of the present invention, data is processed and displayed in such a flow.

  FIG. 4 is a block diagram when an external data processing apparatus such as a personal computer is connected to the pedometer 8b according to the present invention. Here, a memory 13 for storing data and a communication circuit 14 for forming an interface with an external data processing apparatus are added. FIG. 5 is a diagram schematically showing data exchange between the pedometer 15 and the personal computer 16 according to the present invention.

  As described above, according to the present invention, when exercising, it is possible to provide a pedometer that can provide information relating to heat stroke prevention reflecting the state of the environment in real time. It can be prevented beforehand. It should be noted that the present invention is not limited to the above-described embodiment, and can be conceived by those having ordinary knowledge in the field of the present invention, and design changes within a range that does not depart from the gist including various modifications and corrections.
