Taking LQG as an example, as shown in fig. 6, the logic check circuit: JLJ normally is to suck, when the train is pressed into the last section of the departure route (taking 3DG as an example) after the departure signal to the XF port is opened, XFCZJ falls down, and the first self-closing circuit of X1LQG-JLJ is cut off. Meanwhile, as XFCZJ falls, the 3DGJ falling mechanism is connected with a second self-closing circuit (as JLJ loses power at the moment of relay conversion, a JWXC-H340 slow-release relay is adopted at JLJ). When the train sequentially occupies X1LQG, X1LQG-QGJF falls down, the second self-closing circuit is cut off, and X1LQG-JLJ is in loss of magnetism and falls down, so that the BJ relay circuit cannot be constructed because the X1LQG-QGJF relay falls down, and the train belongs to normal occupation. As X1LQG-QGJF falls down, and meanwhile X1LQG-JLJ falls down, after a train is cleared of 3DG, the 3DGJF relay is sucked up, and XFCZJ excitation is sucked up and self-closed. When the train continues to run and is pressed into X2LQG, X2LQG-GJ falls down, and after the train is cleared of X1LQG, the X1LQG-QGJF relay is sucked up, and a JLJ exciting circuit is switched on at the moment, JLJ is excited to suck up and self-close. Analog test circuit of the device of this embodiment: checking the logic checking section JLJ for excitation and self-closing circuits through the analog interface condition "(2), (4) and (5)" status lines, and checking the corresponding interface lines; the present logic section is simulated to check the output status lines "(1), (3), (6)", the corresponding relays xfzczj, X2LQJ-JLJ status and interface lines by simulating the box-packed circuit.

Take 3JG as an example, as shown in fig. 7.

Logic checking circuit: JLJ normally is to suck, when the X-port car receiving signal is opened, the train is pressed in 2JG,2JG-QGJF, JLJ falls down, 2JG-GJF falls down, and the first self-closing circuit of 3JG-JLJ is cut off; when the train sequentially occupies 3JG, 3JG-QGJF falls down, the second self-closing circuit is cut off, and 3JG-JLJ is in loss of magnetism and falls down, so that the 3JG-QGJF relay falls down, and the BJ relay circuit cannot be connected, and the train belongs to normal occupation. When the train continues to run in the pressing station (IAG for example), the XLXJF falls down, and the XJZ exciting circuit is cut off to communicate with the XJZ self-closing circuit. When the train goes out of 3JG, the XJZ is used for sucking up and restarting the communication 3JG-JLJ exciting circuit to suck up and automatically close.

Analog test circuit of the device of this embodiment: checking the logic checking section JLJ excitation and self-closing circuits through the analog interface condition "(1) and" (4) "status lines, and checking the corresponding interface lines; the analog box circuit simulates the output state lines (2) and (3) of the logic section to check the states and interface lines of the corresponding relays X-JZJ and 2 JG-JLJ.
