[0069] like Figure 1 As shown, an embodiment of the present application proposes a subway platform door control device, including a SIG logic control circuit, a PSL logic control circuit, an IBP logic control circuit, and a switch door control circuit arranged on a PCB board.

[0070] The SIG logic control circuit is used to output a SIG enable control signal and a corresponding gate control signal according to the SIG switch enable signal, the PSL enable terminal control signal, the IBP enable terminal control signal and the SIG switch control signal.

[0071] The above-mentioned PSL enable end control signal and IBP enable end control signal both include an enable control signal and an enable non-control signal. For example, the PSL enable end control signal can be a PSL enable control signal or a PSL enable non-control signal. The IBP enable end control signal can be an IBP enable control signal or an IBP enable non-control signal.

[0072] In some embodiments, when the PSL enable end control signal and the IBP enable end control signal are the PSL enable non-control signal and the IBP enable non-control signal, the SIG logic control circuit outputs the SIG enable control signal and the corresponding gate control signal according to the SIG switch enable signal, the PSL enable non-control signal, the IBP enable non-control signal and the SIG switch control signal. In some embodiments, when the PSL enable end control signal and the IBP enable end control signal are the PSL enable control signal and the IBP enable control signal, the SIG logic control circuit outputs the SIG enable control signal and the corresponding gate control signal according to the SIG switch enable signal, the PSL enable control signal, the IBP enable control signal and the SIG switch control signal. In other embodiments, the PSL enable end control signal and the IBP enable end control signal can also be the PSL enable control signal and the IBP enable non-control signal, or the PSL enable non-control signal and the IBP enable control signal.

[0073] Among them, the priority of the IBP enable end control signal is higher than the priority of the PSL enable end control signal, and the priority of the PSL enable end control signal is higher than the priority of the SIG enable control signal.

[0074] The PSL logic control circuit is used to output a corresponding gate control signal according to the PSL enable terminal control signal, the IBP enable terminal control signal, the PSL switch enable signal and the PSL switch control signal.

[0075] In some embodiments, the PSL enable end control signal can be a PSL enable control signal or a PSL enable non-control signal; the IBP enable end control signal can be an IBP enable control signal or an IBP enable non-control signal, and the PSL logic control circuit outputs a corresponding gate control signal according to the PSL enable end control signal, the IBP enable end control signal, the PSL switch enable signal and the PSL switch control signal.

[0076] The IBP logic control circuit includes at least one switch tube, which is used to output a corresponding gate control signal according to an IBP switch enable signal and an IBP switch control signal.

[0077] The door opening and closing control circuit is connected to the SIG logic control circuit, the PSL logic control circuit, and the IBP logic control circuit, and is used to control the opening or closing of the subway platform door according to the door control signal.

[0079] Specifically, when the IBP switch enable signal is a high level signal, if the IBP door opening control signal is a high level, the output door opening control signal controls the subway platform door to open, and if the IBP door closing control signal is a high level, the output door closing control signal controls the subway platform door to close. When the IBP switch enable signal is a low level signal, and the PSL switch enable signal is a high level signal, if the PSL door opening control signal is a high level, the output door opening control signal controls the subway platform door to open, and if the PSL door closing control signal is a high level, the output door closing control signal controls the subway platform door to close. When the IBP switch enable signal is a low level signal, and the PSL switch enable signal is a low level signal, and the SIG switch enable signal is a high level signal, if the SIG door opening control signal is a high level, the output door opening control signal controls the subway platform door to open, and if the SIG door closing control signal is a high level, the output door closing control signal controls the subway platform door to close.
