Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to GPS (Global).
The present invention relates to a position information transmission device for communicating the position of a person or an object by automatically acquiring position information by a positioning system satellite and outputting the position information by radio waves.

In mountain climbing, exploration, etc., it is very important socially to prepare a system for reporting the position of the climber or explorer in case of emergency such as a disaster, and receiving a rescue. Alternatively, taxi companies, logistics companies, etc. need to always manage the traveling positions of automobiles.

As described above, in a situation where it is difficult to be found by a third party because it is buried in a large area, the location of the person or thing is notified, and the third person can easily find the position of the person or thing. A device capable of confirming is required.

The present invention provides a position information transmitting device which can accurately and easily notify the position of the originator in an emergency in any place in the world.

[0005]

2. Description of the Related Art FIG. 13 shows a conventional method of notifying position information by a transceiver. Conventionally, a climber or the like communicates the location of a mountain by a transceiver.

In the figure, 200 is a transceiver on the transmitting side, 201 is a microphone of the transceiver 200, 202 is a transceiver on the receiving side, and 203 is a speaker of the transceiver 202. Reference numeral 204 is a sender, such as a mountaineer. Reference numeral 205 denotes a receiver, who is a third party who receives the contact of the sender.

[0007] Conventionally, when informing the location of a mountain climbing or the like, a mountaineer or the like carries the transceiver 200 and refers to the map from the surrounding conditions (mountain position, river position, etc.) to confirm the position by himself. Then, position information was voice-input to the microphone of the transceiver 200. Then, the position information input by voice by the sender 204 (climbing person, etc.) is output by radio waves. Then, the radio wave is transmitted to the transceiver (reception side) 2
When it is received by 02, the speaker 203 outputs the position information input by the caller by voice, and the receiver (third party) 205
Knows that the caller 204 is in distress and knows its location.

[0008]

Conventionally, the communication of the position of a climber or the like has been performed by the transceiver as described above, so that it is necessary for the transmitting side to operate the transceiver. The operation of the transceiver is complicated, and it is difficult to make a call when the caller's physical strength is weak.
Also, the receiving side is not always ready to receive, and cannot receive the caller's notification while doing other work or sleeping at night. In addition, the battery was exhausted so much that it could not be used continuously for a long time.

Further, since the caller needs to confirm the position himself / herself from the surrounding situation, it is difficult to notify the position accurately. It is an object of the present invention to provide a position information transmitting device that can output accurate position information by a simple operation and can make reliable contact.

[0010]

FIG. 4 shows the configuration of an embodiment of the present invention. (a) is Example 1.

Generally, the position information transmitting device is of a portable type, and the power source is a battery. The output must be as high as possible so that the outgoing signal can fly far. Also, the operating time must be as long as possible. The transmission intervals do not have to be continuous, and intermittent (for example, one minute intervals) is also sufficient. Therefore, in the figure, the battery life is extended by intermittently transmitting the transmission signal.

In the figure, 1 is a position information transmitting device, 2 is a GPS receiving unit, 3 is a clock unit, 4 is a recognition code holding unit, 5 is a transmission signal format holding unit, 6 is a transmission signal assembling unit, 7

By intermittently transmitting as described above,
The battery life can be extended. FIG. 4B shows the second embodiment.

(B) shows the configuration in the case of transmitting the outgoing signal by the Morse code. The Morse code transmission can reach a long distance with a small amount of power.
