Abstract

PROBLEM TO BE SOLVED: To provide a method for aiding a rescue operation by a mobile phone of a rescuer side without using a communication line.SOLUTION: By adding functions of a rescue signal transmission system and a rescue signal reception system to one mobile phone, a disaster victim can continually transmit a rescue pulse signal as a rescue signal asking for rescue by the rescue signal transmission system as long as the functions of the mobile phone work even in the case a communication line is unable to use at the time of a disaster or the phone is out of a service area. A searcher side, by the rescue signal reception system, locates a place where the rescue pulse signal transmitted by the disaster victim can be received, and narrows down a search area to a place indicating a strong level to be able to aid rescue operation.

Description

  This invention allows a mobile phone to have a rescue signal transmission function, and a rescue-side mobile phone to have a rescue signal reception function, so that even if the telephone line is paralyzed during a major disaster, the mobile phone holder can carry out rescue activities. Regarding the method.

  The rescue signal transmission system and the reception system using a conventional mobile phone were able to specify the rescue signal transmission location through the base station and perform the rescue operation. However, in the event of a major disaster, the base station cannot be used or the telephone line The receiving system function could not be used due to paralysis, etc., and rescue activities could not be performed.

  The rescue signal transmission system and the rescue signal reception system function are provided to the mobile phone, and the rescue signal transmitted from the mobile phone of the victim without using the communication line can receive the rescue signal from the mobile phone of the rescuer. The challenge is to provide a way to help activities.

In order to solve the above problems, the first invention provides a rescue signal transmission system function to a mobile phone. The rescue signal transmission system is provided with an SOS key on the key of the mobile phone and operates when a distress presses the SOS key. The rescue pulse signal that transmits a rescue pulse signal for several seconds at regular intervals is a weak radio wave that reaches a radius of 10 to 20 m from the source, and can continue to be transmitted until the battery of the mobile phone runs out.
In addition, the second invention adds a rescue signal receiving system function to the mobile phone. The rescue signal receiving system is provided with an SOS reception key on the mobile phone and operates when a rescuer presses the SOS reception key. It can be received directly by the mobile phone without passing through the base station. The received rescue pulse signal can display the level of the strength of the rescue pulse signal on the display screen of the mobile phone.

  According to the first invention and the second invention, by providing a portable telephone with a rescue signal transmission system and a rescue signal receiving system function, the victim can be rescued by pressing the SOS key of the portable telephone. You can work to maintain your physical strength. The rescuer can go near the distress site, specify a strong place where the rescue pulse signal can be received by pressing the SOS reception key of the mobile phone, and narrow down the search range to perform a quick rescue operation.

  In the event of a major disaster, when a communication line is paralyzed, it is not possible to seek rescue with a mobile phone. Many mobile phones on the rescuer side will be used as investigative devices by the spread of mobile phones with a rescue signal transmission system and a rescue signal reception system function in mobile phones possessed by many people at high penetration rates. A quick rescue operation is possible.

It is a block diagram which shows the structure of the rescue signal transmission system which concerns on one Embodiment of this invention, and a mobile telephone with a rescue signal receiving system function.

One embodiment of the present invention is shown in FIG.
The rescue signal transmission system is provided with a SOS transmission key 2 for transmitting a rescue signal on the mobile phone 1. When the SOS transmission key 2 is pressed, the SOS pulse transmission unit 3 is activated and the signal transmitted by the control unit 4 at regular intervals. As a rescue pulse signal transmitted for several seconds, it is transmitted as a rescue pulse signal by the wireless unit 5 and the antenna 6. The signal generated by the SOS pulse transmission unit 3 is common to all mobile phones, and even if a SOS transmission key 2 is pressed due to a malfunction and a rescue pulse signal is transmitted, a general communication line and radio wave use device It is set to a weak radio field strength and frequency band that does not affect. The rescue pulse signal is a radio wave intensity that reaches within a radius of 10 to 20 m from the transmission source, and the signal generated by the SOS pulse transmission unit 3 is a frequency determined differently from noise generated from general electric equipment, and is constant. It can be transmitted continuously for several seconds at intervals, and can continue to be transmitted until the mobile phone 1 is turned off.

In the rescue signal receiving system, the mobile phone 1 is provided with the SOS reception key 7. When the SOS reception key 7 is pressed, the SOS reception sensitivity detection unit 8 operates and the weak radio wave received from the antenna 6 is transmitted to the radio unit 5 control unit 4. The SOS reception sensitivity detection unit 8 determines that the rescue pulse signal is a radio wave having a frequency registered in the memory unit 10, and displays the level sensitivity level on the level display 9 in the case of the rescue pulse signal. The level display 9 displays the strength of the rescue pulse signal as a bar graph in several stages, and can display the approximate distance to the transmission source.

Effects of the embodiment

  According to this embodiment, by adding a rescue signal transmission system and a rescue signal reception system function to a single mobile phone, it can be used as a rescue signal transmitter in the event of a disaster, and the rescue side in the event of a disaster In this situation, any person who has a mobile phone with a function of receiving a rescue signal can cooperate in the search activities and inform the rescue workers of the location of the victim.

Claims (3)

  Eliminates troublesome operations in the event of a disaster and can send a rescue pulse signal continuously for a few seconds at regular intervals with a single button. The rescue pulse signal is sent directly from a mobile phone without using a communication line. A portable telephone with a rescue signal transmission system function.   To be able to cooperate in investigation activities at the time of a disaster, it is possible to receive a rescue pulse signal without using a communication line with a single button, display the level according to the strength of the rescue pulse signal, and display the distance to the source A mobile phone with a rescue signal receiving system function.   A cellular phone provided with the rescue signal transmission system function according to claim 1 and the rescue signal reception system function according to claim 2.
