CDMA20001X/EVDO-based high-speed train state train-ground transmission device

Abstract

The invention discloses a CDMA20001X/EVDO-based high-speed train state train-ground transmission device. The device consists of a main control module, a universal serial bus (USB) module, a universal asynchronous receiver/transmitter (UART) module, an Ethernet module, a CDMA20001X/EVDO2G/3G adaptive module, a global positioning system (GPS) module, an antenna feeder module, a voice prompt module, an all-in-on (AIO) module, a data input/output (DIO) module, a multifunction vehicle bus (MVB) module and a working power supply module. The device has the advantages that: the modules implement acquisition of running state parameters of a high-speed train at the traveling time and acquisition of high-speed train video monitoring information, passenger information and high-speed train running position information together, the information is transmitted to a motor car base or a locomotive depot dispatching center through a CDMA20001X/EVDO adaptive 2G/3G wireless network in real time, and the motor car base or the locomotive depot dispatching center monitors the running condition of the high-speed train in real time, early warns the faults of the high-speed train in time and implements command and dispatch, so that running safety of the high-speed train is ensured. Meanwhile, the modernized and information-based development requirement in Chinese railways at present is met.

Description

technical field [0001] The invention relates to a remote wireless transmission device, in particular to a CDMA20001X / EVDO-based high-speed train state vehicle-to-ground transmission device. Background technique [0002] In the past 15 years, my country's railway construction has developed rapidly. It has experienced electrification transformation, heavy-duty transportation, construction of intercity railway lines, and construction of express railways and high-speed railways, which have effectively promoted the sound and rapid development of my country's national economy. At present, my country's railway operating mileage has reached 90,000 km, ranking second in the world, and the operating mileage of high-speed railways has reached 8,358 km. By 2015, my country's railway operating mileage will reach more than 120,000 kilometers, of which high-speed railways will reach more than 16,000 kilometers. With the high-speed railway as the framework, a 50,000-kilometer express railw...

Problems solved by technology

[0003] Existing wireless transmission devices for locomotives and high-speed trains are all based on GSM/GSM-R and GPRS wireless communication networks, and these networks cannot meet the transmission of large-capacity data such as high-speed train video surveillance

At the same time, the above-mentioned devices basically do not have the function of detecting the running state of the high-speed train, that is to say, such a wireless tra...
