and the parallel port information acquisition module is used for acquiring the position information of the uplink and downlink switch at the current moment.
6. The cab signal on-line comprehensive detection device according to claim 5,
the locomotive signal online comprehensive detection device also comprises a timing module, wherein the timing module is used for presetting time for counting the number of times of the change of the light color, the CPU control module is used for backing up the current light color in real time and accumulating the number of times of the change of the light color, and if the number of times of the change of the light color is more than the specified number of times within the preset reasonable time range of the timing module, the locomotive signal is positioned on the loop in the garage; if the change of the light color is less than the specified times and the light color is continuously a colored light, the cab signal is positioned on the non-loop line; if the color of the lamp is continuously colorless, comparing the current code sending uplink and downlink information with the uplink and downlink switch position information, and if the current code sending uplink and downlink information is consistent with the uplink and downlink switch position information, indicating that the cab signal is positioned on a non-loop line; if not, comparing continuously until the uplink and downlink information are consistent, and then comparing the number of times of the color change of the lamp; or
The locomotive signal on-line comprehensive detection device also comprises a storage module used for storing the existing loop line code sending sequence and the lamp color change sequence, the CPU control module is used for backing up the current lamp color in real time, comparing the lamp color change sequence with the lamp color change sequence in the nonvolatile storage module if the lamp color changes, and indicating that the locomotive signal is positioned on the loop line in the garage if the lamp color change sequence is consistent with the lamp color change sequence in the nonvolatile storage module; and if the light color does not change, continuously acquiring the light color and judging in real time.
