AP box infinite power supply system and power supply method based on same

Abstract

The embodiment of the invention discloses an AP box infinite power supply system and a power supply method based on the same to reduce construction difficulty, save cost and improve reliability of power supply. The system comprises a charging module, an energy receiving antenna and an energy storage device, wherein the charging module is disposed on a train and is configured to send energy wirelessly when the energy receiving antenna is within an energy receiving range; the energy receiving antenna is laid on train operation tracks and connected to the energy storage device for receiving the energy transmitted by the charging module and converting the energy into voltage to be supplied to the energy storage device; and the energy storage device is configured to charge its own energy storage apparatus by using the voltage provided by the energy receiving antenna, wherein the energy stored by the energy storage apparatus is used for powering an AP box.

Description

technical field [0001] The embodiment of the present invention relates to the communication field, and in particular to an AP box unlimited power supply system and a power supply method based on the system. Background technique [0002] At present, my country's urban rail transit has entered the peak period of development, and CBTC (communication-based train control technology) has become the mainstream system for the selection of my country's urban rail transit signaling system. Basic technical characteristics of the CBTC system: [0003] (1) Use wireless methods such as free wave directional antennas, cross loops, wave guides, and leaky cables to replace traditional track circuits; realize high-speed information transmission between trains and ground; [0004] (2) Relying on query transponders or beacons to realize train positioning verification; [0005] (3) Based on the line database, the train sends a position report in real time and accepts the movement authorization...

AI Technical Summary

Problems solved by technology

[0009] 1. The distance between urban rail transit stations is about 2 kilometers. Considering the redundant network, 20 pairs of cables need to be laid along the line. The construction is difficult, and the workload of cable maintenance will be huge in the future;

[0010] 2. For intercity railways, if the distance between stations is greater than 20 kilometers, if the power line of the AP box transmits 20 kilometers, the voltage drop of the power supply will basically be reduced by half, and it will not work normally.
