Next,numerals 10 designate hall call registration devices RSa - RSn which are furnished with hall call registration buttons, and which perform the hall call registration controls of respective floors. These hall call registration devices RSa - RSn are also connected with theelevator control circuit 3 through atransmission line 12.
In addition, theelevator control circuit 3 is configured of anelevator control circuit 30 and atransmission interface 31, and thetransmission interface 31 controls transmissions with the hallcall registration devices 10 and thedevices 80, 90 and 91 in theelevator cage 8. - Fig. 3 is a block diagram showing the
elevator control unit 30. By the way, in Fig. 3, the same constituents as in Fig. 2 are assigned the same reference numerals.
Theelevator control unit 30 is configured of a central processing unit (hereinbelow, termed "CPU") 3001 which is control means for executing various arithmetic processes, apulse count unit 3004 which counts the pulse outputs of thepulse encoder 2, aROM 3005 in which the control programs of the CPU are stored, a 2-port RAM 3003 which exchanges data with thetransmission interface 31, aRAM 3002 in which the arithmetic data of the CPU, etc. are stored, and thePWM unit 3006 which outputs PWM instructions for controlling the ascent and descent of theelevator cage 8 in accordance with the arithmetic results of the CPU. - Next, the operation of the

Fig. 1 is a block diagram of the respective S/W functions of theelevator control unit 30, while Fig. 4 is a flow chart for incarnating the S/W function blocks in Fig. 1, and this program is stored in theROM 3005.
Referring to Fig. 1,numeral 301 designates load-in-elevator-cage detection means, which detects a load in theelevator cage 8 on the basis of a weighing signal WH from theweighing device 81. Numeral 302 designates picture-in-cage detection means for detecting a passenger in the cage by a camera picture PT which is sent from a camera (not shown) mounted in theelevator cage 8. Numeral 303 designates elevator running mode detection means, which detects that the elevator has shifted into a closed-door running-cessation state having no direction.
Numeral 304 designates pseudo-confinement detection means. In general, a situation where the elevator cage 8 stops in a non-floor-arrival state and where a passenger is confined therein is termed a "confinement state". This embodiment 1, however, deals with a state where theelevator cage 8 has arrived at a predetermined floor, and where a passenger has not gotten off the elevator cage for such a reason as failing to get off or where he/she cannot get off. This state shall be termed "pseudo confinement", and the passenger shall be termed a "pseudo-confined passenger". The pseudo-confinement detection means 304 detects the pseudo-confined passenger who remains in the cage without getting off (being able to get off) the cage for such a reason as having failed to get off the cage, on the basis of detection signals from the load-in-cage detection means 301 or picture-in-cage detection means 302 and the elevator running mode detection means 303. Numeral 306 designates announcement issue means for issuing a getting-off prompt announcement ANE for prompting the passenger to a movement for getting off, on the basis of an announcement ringing instruction from the pseudo-confinement detection means 304.

Referring to Fig. 4, at astep 41, it is decided if the running cessation state of the elevator has continued for a predetermined time period (60 sec in this example). Here, the "running cessation state of the elevator" signifies a state where the elevator has fallen into a closed-door running-cessation state having no direction, or a state where the rescue running operation of causing the elevator to arrive at a refuge floor or the nearest floor has been performed at the occurrence of a disaster, and where the elevator has been thereafter brought into a closed-door running-cessation state for the sake of safety, so that a user passenger cannot use the elevator any longer.
When the elevator running-cessation state does not continue for, at least, the predetermined time period, the decision result of thestep 41 becomes "NO", and the routine proceeds to astep 48, at which an ordinary running operation is continued.
On the other hand, in a case where the elevator running-cessation state has continued for, at least, the predetermined time period, the decision result of thestep 41 becomes "YES", and the routine proceeds to astep 42, at which the existence or nonexistence of a passenger in theelevator cage 8 is decided. At thestep 42, it is decided, for example, if a weighing detection value is equal to, at least, a predetermined value of 30 kg. Although the existence or nonexistence of the passenger in theelevator cage 8 is decided by the weighing detection value here, a camera may be installed in theelevator cage 8 so as to decide the existence or nonexistence of the passenger by a picture-in-cage PT, or these measures may well be combined.
When the weighing detection value is less than the predetermined value, the decision result of thestep 42 becomes "NO" with the passenger regarded as being nonexistent in the elevator cage, the routine proceeds to astep 49, at which the running cessation state is continued. In a case where the weighing detection value is equal to, at least, the predetermined value, the decision result of thestep 42 becomes "YES" with the passenger regarded as being existent in theelevator cage 8, the routine proceeds to astep 43, at which a getting-off prompt announcement issue ANE for prompting the passenger to a movement for getting off the elevator cage is made, for example, "Please push the door opening button" is announced. Simultaneously, in a case where a door-opening-button lamp and an illuminator in the cage are put out, they are lit up at astep 44.
At astep 45, it is decided if the door opening button in theelevator cage 8 has been depressed. In a case where the button has been depressed, the decision result of thestep 45 becomes "YES", and the routine proceeds to astep 46, at which the door of theelevator cage 8 is opened. Simultaneously, "Please get off when the door is opened" is announced at astep 47.
In a case where the door opening button has not been depressed, the decision result of thestep 45 becomes "NO", and if the non-depressed state of the button has continued for a predetermined time period (for example, 60 sec) is decided at astep 50. In a case where the state has not continued for the predetermined time period, thestep 45 is repeated.
In a case where it has been decided at thestep 50 that the non-depressed state has continued for, at least, the predetermined time period, the decision result of thestep 50 becomes "YES". Then, it is judged that the passenger in theelevator cage 8 is in a situation where he/she cannot perform the movement for getting off the cage, and the door of theelevator cage 8 is opened at astep 51. Simultaneously, "Boo Xn" is announced at astep 52.
The announcement at thestep 52 is not the getting-off prompt announcement issue ANE for prompting the passenger to the movement for getting off the cage, but it is a caution announcement ANC for reporting that the passenger might be in an immobile state in theelevator cage 8, to the surrounding dwellers, etc. outside the elevator cage. - As described above, the elevator control apparatus is configured so as to make the getting-off prompt announcement issue which prompts the passenger having failed to get off the cage, to the movement for getting off the cage. Therefore, even in a case where the passenger has failed to escape from the cage after the elevator has arrived at the refuge floor or the nearest floor on account of the rescue running operation at the occurrence of the disaster, or the like, the apparatus has the advantage that the pseudo confinement state is avoidable.
Besides, the elevator control apparatus is configured so that, even in the state where the passenger in the cage cannot get off the cage for any reason, the door may be forcibly opened when the predetermined condition has held true. Therefore, the apparatus has the advantages that the safety is enhanced more, and that a suspicious person, a child, an elderly person or the like can be prevented from staying in the cage for a long time.
