An interlocking control device for a multiple-unit safety circuit is provided, which includes: a protective grounding switch control branch which includes: a pantograph rising pneumatic circuit cut-off valve, a protective grounding switch turn-off pneumatic circuit cut-off valve and a protective grounding switch turn-off solenoid valve which are connected in series. When high-voltage equipment of a multiple-unit train is under maintenance or is powered by an external power supply, a protective grounding switch is turned on, cocks of the pantograph rising pneumatic circuit cut-off valve and the protective grounding switch turn-off pneumatic circuit cut-off valve are rotated to open a cover of a key box, the protective grounding switch control branch is disconnected, the protective grounding switch turn-off solenoid valve connected in series in the protective grounding switch control branch is powered off to maintain the protective grounding switch in an on state.
