Problems solved by technology

[0003] However, due to the fact that the communication core networks between different countries have not realized interconnection and interoperability, the current solution can only work normally when operating in one country, and cannot use a set of radio stations to communicate with the station normally when operating across borders

Embodiment 1

[0035] A method for automatically switching radio stations of a power-concentrated EMU operating across borders, comprising the following steps:

[0036] (1) After the EMU enters country B from country A, the locomotive remote monitoring and diagnosis system 200 obtains the latitude and longitude of the location of the EMU.

[0037] Further, before the EMU runs, the latitude and longitude information of the countries passed through is input into the central control unit 300 .

[0038] Moreover, the on-board communication station 100 sends the longitude and latitude information of the location of the EMU to the locomotive remote monitoring and diagnosis system 200 in real time.

[0039] In this step, the in-vehicle communication station 100 obtains the positioning information of the EMU in real time through the GPS positioning module installed inside, that is, the latitude and longitude information, and transmits the real-time latitude and longitude information to the locomotiv...

Embodiment 2

[0049] In order to realize the method of embodiment 1, such as figure 1 As shown, the present invention also provides a radio station automatic switching system for a cross-border operation of centralized power EMUs, including a vehicle communication station 100, a locomotive remote monitoring and diagnosis system 200, a central control unit 300, a digital output unit 400, a Country decoding module 500, country B decoding module 600, vehicle communication station host 700 and vehicle communication station microphone 800, wherein: vehicle communication station 100 is used to locate the real-time latitude and longitude information of the EMU, and judge the location of the EMU according to the latitude and longitude information In the country; the locomotive remote monitoring and diagnosis system 200 is used to record the operation information of the EMU and transmit it to the ground equipment, the locomotive remote monitoring and diagnosis system 200 is connected with the vehicle...

Abstract

The invention provides an automatic radio station switching method for a power-concentrated motor train unit running in a cross-border mode, and relates to the technical field of radio station cross-border switching. A locomotive remote monitoring and diagnosis system obtains the longitude and latitude of the position where the motor train unit is located and forwards the longitude and latitude information of the position where the motor train unit is located in real time to a central control unit; and the central control unit compares and confirms, and sends a confirmation result to the digital quantity output unit, the digital quantity output unit controls a corresponding decoding module to supply power, sends decoding information to a vehicle-mounted communication radio host, and contacts with a station through a vehicle-mounted communication radio microphone to complete automatic switching of the vehicle-mounted communication radio. According to the invention, automatic switching of the cross-border operation vehicle-mounted communication radio stations of the power-concentrated motor train unit is realized, safety accidents caused by human factors are avoided, the application range of the power-concentrated motor train unit is widened, and one set of railway transportation equipment can meet communication systems of multiple countries.

Description

technical field [0001] The invention relates to the technical field of cross-border switching of radio stations, in particular to a method for automatically switching radio stations of a power-concentrated EMU running across borders. Background technique [0002] The concentrated power EMU is composed of power cars, trailers, and control cars. According to the needs of railway transportation, long groups (1 power car + 9-18 trailers + 1 power car) and short groups (1 power car + 7 cars) are formed. Trailer + 1 control vehicle), wherein the power vehicle is a locomotive with power, the trailer is a vehicle for carrying passengers, and the control vehicle is a vehicle for carrying passengers with a driver's cab and the function of controlling the power vehicle. The power-concentrated EMU can realize double-end operation. When running on the railway line, there is no need to perform a U-turn operation, and the reversing operation can be completed after directly changing the end...
