Abstract

The invention relates to a portable Beidou communication emergency terminal hardware structure with low power consumption. In the communication technical scheme, a universal series bus (USB) interface is connected with an intelligent terminal (such as an intelligent mobile phone, a tablet computer and the like) so that the intelligent terminal completes the man-machine interaction; and the emergency communication information can complete the Beidou communication task in a keying manner via the terminal. The invention further discloses a power supply design relevant to the portable terminal and an input and output (IO) sharing method for reducing the used singlechip pins; and the portable Beidou terminal realized by the way is combined with the application software customized on a special Beidou information service centre and the intelligent terminal, so that the emergency communication application under the environment without communication network signals can be effectively met.

Description

technical field [0001] The invention relates to a low power consumption portable Beidou communication emergency terminal hardware structure. Background technique [0002] Emergency communication is of great significance in many fields of production and life. At present, most of them use GSM or 3G communication methods. However, due to the coverage of communication base stations in different communication systems, there are blind or weak areas of the signal, which makes it difficult for emergency applications. Large uncertainty, and it is mainly used for the call function, and the positioning cannot be realized through the signal, or even if it can be positioned, it is highly dependent on the base station, and it is still difficult to apply to the application of emergency communication (such as outdoor sports). Contents of the invention [0003] The purpose of the present invention is to provide a low-power portable Beidou communication emergency terminal hardware structure...
