Description

TECHNICAL FIELD

[0001] The utility model relates to high -speed rail JRU test technical field especially, and relates to a kind of high-speed rail JRU test adaptation device. BACKGROUND

[0002] JRU (Juridical Recording Unit) is the event recording equipment installed under the UNISIG framework for running in high-speed rail motor train unit, commonly known as the black box of high-speed train. JRU is used to record the original information collected by on-board equipment during train operation and the control information output by on-board equipment. It records all key data during high-speed train operation. Currently, high-speed trains running at 300 km / h are equipped with JRU certified by ETCS, while signal systems on lines running at 200 km / h use domestic LKJ (Train Operation Monitoring and Recording Device) recorders. The data recorded in JRU not only ensures the safety of train operation, but also has great significance for the research of high-speed trains and railway technology.

[0003] JRU data provides first-hand data materials for the construction of high-speed railways, helping technical personnel better locate problems, solve problems and propose better solutions. Therefore, the analysis of JRU data is very important. Currently, some research institutions have made certain achievements in studying the operation of high-speed trains using JRU data and are leading in the world. Research results include real-time transmission of train data, analysis of messages, and intuitive display of train operation status, thereby providing a basis for analysis and maintenance of equipment failures and providing an effective monitoring means for safe operation of trains.

[0004] HFT-01 hardware function test equipment (hereinafter referred to as "JRU test equipment") is used for hardware function test of JRU. During testing, multiple cables are used to connect the test equipment and the JRU under test directly.
