Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pedestrian navigation device, and more particularly to a pedestrian navigation device suitable for use in combination with a mobile phone.

[0002]

2. Description of the Related Art As a pedestrian navigation device, Japanese Patent Laid-Open No. 10-318777 discloses a GPS positioning means for positioning an initial position of a pedestrian before moving based on positioning information received from GPS satellites. An azimuth detecting unit that is mounted and detects azimuth data before the pedestrian moves, a pedestrian detecting unit that is mounted on the pedestrian and detects step number data when the pedestrian moves, and a pedestrian mounted pedestrian , Angular velocity detection means for detecting angular velocity data acting on the pedestrian when moving, azimuth data detected by the azimuth detection means, step count data detected by the step count detection means,
Self-supporting positioning means for positioning the post-movement position of a pedestrian from the angular velocity data detected by the angular velocity detecting means;
It is disclosed that the present position calculation means calculates the current position of a pedestrian using the initial position measured by the positioning means and the moved position measured by the independent positioning means.

[0003]

According to the conventional pedestrian navigation device described above, there is an advantage that the position information of the pedestrian can be accurately obtained, but various devices for obtaining the position information are provided. There is a problem that it is necessary to wear it, it is troublesome when going out, and it is easy to forget to attach the device. In addition, for a pedestrian who walks to improve his / her health, the information on the walking speed cannot be obtained, which is unsatisfactory.

An object of the present invention is to provide a pedestrian navigation device which is extremely useful for pedestrians who walk to improve their health, while reducing the trouble of going out and forgetting to wear the device as much as possible.

[0005]

Means for Solving the Problems and Effects of the Invention A pedestrian navigation device according to the present invention requires a GPS receiver, a direction sensor indicating the direction in which the tip of the footwear is facing, a step counter for counting the number of times the footwear has landed, The transmitter for transmitting the information of the above to the base station and the power supply for supplying power to these are incorporated in the footwear main body, and the walking information processing means provided in at least one of the footwear main body and the base station,
It has a calculating means for obtaining a walking distance and a walking speed from the step width of the footwear wearer, the number of steps of the step counter and the walking time which are measured in advance.

The footwear body can be used in various forms according to the purpose, and for walking for health promotion, for example,
Walking or jogging shoes are used, and short shoes without boots, boots, sandals, etc. are also used as appropriate. Further, in order to incorporate various devices such as a GPS receiver, a direction sensor, a step counter, a transmitter, and a power source into the footwear body, for example, a hollow portion is provided at the bottom of the heel of the footwear body, and water is especially used among the various equipment. Built into this is something weak to
Items that do not fit here may be integrated with the body of the footwear by an appropriate method such as attaching to the outer surface of the heel. The hollow portion may be provided on the toe side instead of the heel. The walking information processing means is in the form of an IC chip and is housed in the hollow portion of the footwear body. This walking information processing means does not necessarily have to be provided on the footwear side, but a part or all of it can be provided on the base station side.

According to the pedestrian navigation device of the present invention, the current direction of travel of the footwear wearer can be confirmed by the direction sensor, and the footwear wearer can be worn by multiplying the step count of the footwear wearer by the footwear wearer's average stride. The approximate distance from the departure point of the person can be confirmed. Further, the current position of the footwear wearer can be obtained by adding the walking distance of the footwear wearer in a vector manner. Then, by combining the current position calculation by adding the walking distance of the footwear wearer in a vector manner and the position detection by GPS (= Global Positioning System), the roughness of GPS detection accuracy is compensated for With high position detection,
The position of the wearer of footwear can be detected even in an underground shopping area where it is difficult to receive radio waves with a GPS receiver.

Further, as described above, not only can the present position of the footwear wearer be detected from a remote place, but also the number of steps, walking time and walking speed can be obtained.
It is also useful for pedestrians who walk to improve their health. The footwear is always worn when going out, and since the means for transmitting position information and walking information is incorporated into the footwear, it is time-consuming to get out with the means necessary for detecting the position. And it is possible to reduce forgetting to put it on as much as possible.

In the above device, the base station is fixed at the home, school, hospital, or other facility of the footwear wearer, and the display device of the personal computer is used as a means for displaying the footwear wearer information. But of course,
The transmitter on the footwear side has a mobile phone terminal function of transmitting footwear wearer information to a mobile phone as a base station and displaying the information on the display, and a message corresponding to the footwear wearer information is sent to the mobile phone. It is preferable that the sender can reply to the transmitter. In this way, even when you go out from home, when you come home from school, hospital, etc.,
This navigation device can be used.

On the footwear body side, a transmitter, a receiver,
A battery is required to supply power to the step counter, orientation sensor, etc., but this battery may be energized at all times, and a piezoelectric element that energizes when pressure is applied is used. Alternatively, it may be turned on only when a small amount of pressure is applied to the bottom of the body of the footwear by wearing the footwear. If the device is turned on only when pressure is applied to the bottom of the footwear body, the battery is consumed less and the information transmission function can be maintained for a long time because electricity is supplied only when the wearer wears it. To do this, it is of course possible that there is a gap between one of the conducting wires and the battery when not worn, and the conducting wire contacts the battery only when worn.

Further, the above battery is used as a secondary battery, and a piezoelectric power generator for charging the secondary battery with electric energy obtained by vibrating a diaphragm composed of a metal plate and a piezoelectric element with walking is provided. You may use a power supply that has power. The secondary battery is not limited to being rechargeable, but may be a capacitor that only stores electricity. Piezoelectric generators, for example, have piezoelectric elements attached to both sides of a metal plate and vibrate to obtain electric energy. The obtained electric energy is stored in a secondary battery. The problem that the device cannot be used is solved.
