Description

  The present invention relates to a mobile communication device. Moreover, it is related with the relief assistance method. For example, it relates to disaster relief in mountainous areas and desert areas, sea rescue in the sea and rivers.

As a conventional technique, there is a distress relief system using a low altitude orbiting satellite (LEO) mainly in the United States, Canada, France and Russia.
The LEO satellite receives a distress beacon from a dedicated wireless device possessed by the victim when passing over the victim and then transmits a signal when passing over 39 dedicated ground stations located in the world. The ground station estimates the position of the victim with accuracy of 30 km using the Doppler information of the signal, etc., issues a command to the rescue center, and performs rescue activities. The LEO satellite can be contacted only when it passes over the victim, so there will be a time delay, but it is said that the real-time performance has been improved by adding a disaster rescue function to the geostationary satellite.

The Journal of the Institute of Electronics, Information and Communication Engineers (Vol. 82, No. 12, pp. 1207-1215) describes GPS (Global Positioning System) technology.
According to the Journal of the Institute of Electronics, Information and Communication Engineers, GPS has four artificial satellites arranged in six orbits with different ascending point inclination angles of 55 degrees and ascending intersection longitudes of 60 degrees, and 24 satellites cover the whole earth. It is said to cover and fulfill the positioning function. The positioning method is supposed to be performed as follows. First, the time taken for radio waves emitted from any of the four satellites to reach the user receiver is measured, and the distance to the satellite is measured by multiplying by the speed of light C. Then, the four satellites are divided into two groups, and the two satellites are composed of the rotational hyperbola focusing on the two satellites composed of the difference in distance from the two satellites in one group and the difference in distance from the two satellites in the other group. Find the intersection on the earth with a rotating hyperbola with the focus on. The position of the user receiver is obtained from this intersection.

By adding the case where the sea level position is 0 m, that is, when the user is on the sea surface, to the determination condition, the erroneous detection of the landing detection unit 62 that is simply wet with water is eliminated, and the need for rescue is more accurately detected. Judgment can be made.

In the above description, the determination unit 40 may determine after a predetermined delay time has elapsed when determining that the user needs to be rescued.
For example, when the landing is detected from the ship and the landing detection unit 62 has detected the landing even after 5 minutes have elapsed from the detection of the landing, the determination unit 40 can provide relief to the user. Judge that it is necessary. It is also envisaged that the user will be able to crawl on the ship and others or be helped by friends within 5 minutes.
In addition, for example, the flow velocity detection unit 61 detects the water pressure by the ocean current, estimates that the relative velocity between the ocean current velocity and the moving velocity of the user is small based on the water pressure, and detects the predetermined water pressure even after 5 minutes. In the case where it is left as it is, the determination unit 40 determines that the user needs to be rescued. If it is within 5 minutes, it is assumed that the user is merely playing.
In addition, for example, when the predetermined water pressure remains detected even after three hours have elapsed after the water amount detected by the detection unit 60 via the water amount detection unit 64 is less than the predetermined water amount, The determination unit 40 determines that the user needs help. If it is within 3 hours, it is assumed that the user can evacuate to a nearby safe area by himself / herself.
