on the same floor, an upper secondary leveling zone is adjacent to the upper side of a leveling target zone, a lower secondary leveling zone is adjacent to the lower side of the leveling target zone, an upper door zone is adjacent to the upper side of the upper secondary leveling zone, a lower door zone is adjacent to the lower side of the lower secondary leveling zone, the upper leveling zone is adjacent to the upper side of the upper door zone, and the lower leveling zone is adjacent to the lower side of the lower door zone;
the elevator car position sensor also comprises an upper leveling position sensor (DZU) and a lower leveling position sensor (DZD);
when the elevator car sill is positioned in an upper leveling zone, an upper door zone, an upper releveling zone or a leveling target zone of a floor where an upper leveling position sensor (DZU) is positioned, the upper leveling position sensor (DZU) outputs a first state signal, otherwise, a second state signal is output;
when the sill of the elevator car is positioned in a lower leveling zone, a lower door zone, a lower re-leveling zone or a leveling target zone of a floor where a lower leveling position sensor (DZD) is positioned, the lower leveling position sensor (DZD) outputs a first state signal, otherwise, a second state signal is output;
when the controller or the elevator car accidental movement protection system outputs a second state signal by an upper leveling position sensor (DZU) or a lower leveling position sensor (DZD) on the same floor, the controller or the elevator car accidental movement protection system judges that the elevator car is out of an upper door area, a lower door area, an upper re-leveling area, a lower re-leveling area and a leveling target area.
11. The elevator car accidental movement protection system function test device of claim 1,
the elevator car accidental movement protection system sends UCMP action signals to the controller if UCMP emergency stop protection is triggered;
and the controller is used for sending the received UCMP action signal to a display screen of the human-computer interaction device for display.
