The invention discloses a semi-physical
simulation platform for vehicle-mounted controller test. The semi-physical
simulation platform comprises a sensor operation
system, a vehicle-mounted controller, a
software simulation train system and a power supply
system, wherein the sensor operation system comprises a rotating bracket, a driving motor, an acceleration sensor, a Doppler
radar, an annunciator searcher and a speed sensor, wherein the driving motor is used for driving the rotating bracket to rotate; the acceleration sensor and the Doppler
radar are fixed on the rotating bracket; the speed sensor is used for measuring the speed of the rotating bracket; and the speed sensor, the acceleration sensor, the Doppler
radar and the annunciator searcher are models actually used in a railway
train. According to the semi-physical simulation platform for the vehicle-mounted controller test, real rail
train sensors are adopted; the speed sensor, the acceleration sensor, the Doppler radar and an annunciator antenna are arranged at the different positions of the rotating bracket, the sensors are operated according to real work theories, the inputs and outputs of real sensors are provided for the vehicle-mounted controller, so that an environment extremely simulated with a real operation environment is provided for the vehicle-mounted controller.
