Device for detecting ATP (Automatic Train Protection) system

The utility model discloses a device for detecting an ATP (Automatic Train Protection) system. The device comprises main control equipment, ATP interface equipment and a line simulation equipment, wherein a control instruction is sent by the main control equipment; the ATP interface equipment receives the control instruction, sends a speed testing signal according to the control instruction, converts the control instruction into a control signal and converts the control instruction into a testing signal received by the ATP system to be tested according to the control signal; and the ATP system to be tested receives the testing signal for testing, feed backs a digital signal to the line simulation equipment and feed backs the digital signal to the main control equipment by the ATP interface equipment. The device disclosed by the utility model has the advantages that the whole ATP system to be tested can be tested, so that the problem that whether the quality of the whole ATP system is qualified can not be conf
