As shown in fig. 1, a self-adjusting power signal transceiver includes a main control module, a station identification module, a transmitting/receiving antenna, a power module and a power adjustment module. The main control module adopts a central processing unit based on ARM9, is respectively connected with the platform identification module, the transmitting/receiving antenna, the power supply module and the power regulation module through a PIO interface of the central processing unit, and then is electrically connected with the transmitting/receiving antenna to form a transceiver powered by the power supply module, the main control module controls the working power of the transmitting/receiving antenna through the power regulation module, the power regulation module at least comprises a normal power circuit and a high power circuit, and the platform identification module provides subway platform information for the main control module so that the main control module can select and judge which power circuit is switched on.

The self-power-adjusting signal transceiver of the embodiment is installed on a subway train so as to dynamically adjust the strength of wireless signals in a subway train carriage. Specifically, the transmitting/receiving antenna is a relay between the wireless mobile user terminal and the subway tunnel micro base station, and when the wireless mobile user terminal downloads data, the data is sent to the wireless mobile user terminal by the micro base station through the transmitting/receiving antenna; on the contrary, when the wireless mobile user terminal uploads data, the data is sent to the micro base station by the wireless mobile user terminal through the transmitting/receiving antenna.

In this embodiment, the power adjusting module includes a normal power circuit and a high power circuit, when the subway train is in a platform or operates in a short station tunnel interval, the main control module controls to switch on the normal power circuit, and the transmitting/receiving antenna operates at normal power; when the subway train runs between long station tunnels, the master control module controls to switch on the high-power circuit, the transmitting/receiving antenna operates with relatively large power, and wireless signals of a subway train carriage are increased, so that the subway train is guaranteed to keep relatively stable strength of the wireless signals in the carriage in the whole running process, and experience of passengers during riding is improved.

It should be noted that the identification signal of the platform identification module is the basis for the adjustment of the main control module, and the corresponding adjustment is performed only when the main control module can determine that the train is in the long-station tunnel interval. The platform identification module can be implemented in various ways, and in one embodiment, the platform identification module is directly connected with the train control host, and the arrival information of the train is directly sent to the platform identification module.

For example, the counting can be realized by a light sensor counting mode, when a train passes through a platform interval, the light intensity changes once, the counting is performed once, and the current running platform interval of the train running can be judged by combining the running line and the platform information of the train. In the embodiment, in order to improve the accuracy, counting initialization can be performed once when the train is ended, so that the automatic proofreading function is realized, and manual maintenance is reduced. In addition, the storage unit stores the information of the train operation line and the platform in the embodiment and is set by the maintenance personnel.
