Embodiment Construction

[0015] The personal emergency radio communication device provided by the present invention includes a power supply unit, a control unit, an information transceiver unit and an antenna unit.

[0016] The starting circuit 14 in the power supply unit is divided into automatic starting and manual starting. The automatic starting is mainly realized by the automatic induction device on the shell, and the manual starting is controlled by an external switch. It starts automatically when in distress, and does not work normally to save electricity. The battery 13 is a special 10000mAH disposable battery with a validity period of 5 years, which can ensure the normal operation of the system for 48 hours. The start-up circuit 14 is composed of two MOS tubes, and its function is to control the power supply of each part; the voltage-stabilizing circuit 10 is realized by 1117 series voltage-stabilizing chips.

[0017] When the power management circuit 9 is in operation, the voltage regulator ...

Abstract

The invention discloses a personal emergency wireless communication device which comprises a power supply unit, a control unit, a message receiving and sending unit and an antenna unit; each unit is electrically connected; the power supply unit is composed of a power supply management circuit 9, a voltage-stabilized circuit 10, a battery 13 and a starting circuit 14; the control unit is composed of a single chip control circuit 5; the message receiving and sending unit is composed of a GPS module 2, a flash lamp 3, a DDS chip 6, a mirror filter amplifier 11, a power amplifier 12, a power feedback controller 8, an output filter 7 and a message input module 15; the antenna unit is composed of a receiving antenna 1 and a sending antenna 4. The personal emergency wireless communication device solves the problems that work in waiting time is invalid and the technical means for bidirectional message transmission is lacking and is characterized by dynamically adjusting the modulation manner and the message format of an emission signal, receiving and sending the message in multiple working modes and miniaturized antenna, and the device is compatible with a GMDSS.

Description

technical field [0001] The invention relates to an electronic device used for radio positioning and emergency information transmission for ship drivers, aircraft users and land explorers when they are in distress. Background technique [0002] See the article "Low Polar Orbiting Satellite Search and Rescue System" published by Qiu Hongyun and Long Xinguang of Chongqing Institute of Communications in February 2006 in "Space Electronics Technology" magazine, and Wang Haizhu of Tianjin Ocean Shipping Company in "Tianjin Navigation" magazine in January 1997 The article "Development and Application of the COSPAS / SARSAT Search and Rescue Satellite System" was published. The COSPAS / SARSAT system is a global satellite search and rescue system jointly developed by Canada, France, the United States and the former Soviet Union. It is a global maritime distress system promoted by Inmarsat. One of the important components of the security system (GMDSS). The system uses low-altitude pola...
