Abstract

The invention discloses a Beidou message communication terminal suitable for a one-cable access network with low-power power supply and high-power emission. The Beidou message communication terminal is formed by a power supply / charging management circuit, an energy storage circuit, a Beidou transmission and reception circuit and an antenna circuit, an output terminal of a power supply voltage-reduction circuit is connected to an input terminal of the charging management circuit, and an output terminal of the charging management circuit is connected to an input terminal of the energy storage circuit. The charging management circuit and the energy storage circuit are combined so that the charging current and capacitance can be accurately controlled, and the access to a low-power network by an emission Beidou terminal is realized.

Description

Technical field [0001] The patent of the invention belongs to the technical field of satellite navigation applications, and relates to a Beidou message communication terminal, especially a Beidou message communication terminal suitable for accessing a wired data network. Background technique [0002] The Beidou system has the functions of positioning and message communication, and the Beidou terminal access to the information system can realize a variety of integrated applications. The Beidou message communication terminal is a commonly used Beidou terminal mode, which can be connected to the information system to send and receive information and data. [0003] In 2003, the IEEE issued the IEEE802.3af standard, and Ethernet can realize the power supply function. Network equipment can realize data and power supply through a network cable. But there is a limit to the power consumption of the access device, which is usually 12.95W. With the development of technology, the output pow...
