Abstract

The invention discloses a speed testing device of an onboard apparatus of a CTCS level 2 train control system and a testing method. The speed testing device comprises a computer host, a display and aspeed simulation module; the speed simulation module comprises a communication module and a timer module; the computer host is electrically connected with the display, the computer host is electrically connected with the communication module, and the communication module is electrically connected with the timer module. The testing method comprises the following steps of: 1.settingparameters; 2. calculating the speed, the acceleration and jerk of the train at the current moment; 3. calculating and obtaining, according to the calculated speed of the train at the current moment, the speed of thetrain needed to be simulated; and 4. obtaining, according to the simulation speed meter, the speed of the train needed to be simulated. According to the speed testing device and the testing method based on an onboard apparatus of a CTCS level 2 train control system, the simulation of the train speed can be realized, and the operation flexibility and the simulation accuracy are high.

Description

technical field [0001] The invention relates to the technical field of train control system testing, in particular to a speed test device and a test method for CTCS-2 train control vehicle equipment with strong flexibility and high accuracy. Background technique [0002] At present, the existing train control system testing technologies all use motors and motor drivers to match the maximum speed of the motor with the maximum speed regulation range of the motor speed regulator. In addition, a locomotive speed sensor is also used to sense the position change of the gear, obtain the speed signal of the gear, and transmit the speed signal to the locomotive, or use a multivibrator to simulate the speed signal. In the above two methods, the former has a single function and is inflexible in operation, while the latter has poor simulation accuracy. [0003] In response to some of the above problems, the Chinese patent announcement number is CN205786681U. On December 7, 2016, a CRH5...
