Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an elevator security operation system for protecting passengers using the elevator from molesters, thugs, etc.

Conventionally, the security operation method for this type of elevator has been simple: by turning on a specially provided switch, the elevator is stopped at each floor while there is a car call; At present, elevators are rarely used because they take a long time to reach the destination floor, and this invention enables the elevator to be operated for security purposes at the landing, in the control room, or at certain times of the day. If a molestation etc. is discovered, we will take measures to eliminate it.
To provide a crime-prevention operation method for an elevator that is highly effective in preventing crime by notifying the user of this fact, stopping the car at a predetermined floor and waiting with the door open.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.

These are set in the control room, and the respective times are K so that they can be set manually. The time setting signal is supplied to each matching circuit 12, 13, and the matching circuit 12, 134C is designed to receive a time signal from the clock circuit 14. Reference numeral 15 denotes a flip-flop which is set by a coincidence signal from one of the coincidence circuits 12 and reset by a coincidence signal from the other coincidence circuit 13, and its Q output indicates that crime prevention driving is in progress via a selection switch 16. A display device 3 is connected. ′
4f and 17 are flip-flops that are set by operating the security driving request button 6, and the Q output of the flip-flop registers the security driving request and displays it via the button's built-in lamp 6a and the selection switch 16. The reset terminal of the flip-flop 17 is connected to the Q output terminal of the flip-flop 19 via the one-shot multivibrator 18, and the set terminal of the flip-flop 19 receives the driving signal S1 during crime prevention driving. , and the door fully open signal S2 is input to the reset terminal, respectively, and the one-shot multivibrator 18 is activated at the falling edge of the Q output of the flip-flop 19, that is, when the rear door of the car is opened. When the following flip-flop 1 is detected,
The trap is configured to send out a reset pulse to 7.

In Fig. 2, the part surrounded by broken lines constitutes a circuit means A for detecting when a passenger inside the car is attacked by a molester, etc., and as shown in Fig. A pressure sensor installed on the ceiling of the car detects the sounds of passengers' screams, etc.).

The pressure sensor n generates an output when a passenger is pressed against the handrail 21 by a molester or the like, and the output is compared. A reference value Vrefj is added to the other input of the comparator 5, which sets the output level of the pressure sensor ρ when a passenger is pressed against the handrail 21 by a molester or the like. The output of the comparator δ is connected to a timer 26 which sends out an output signal when a passenger is pressed against the handrail 21 inside the car for a certain period of time. It is adapted to be applied to an AND gate n which has one input as the output from 15 or 17.

Also, a filter 2 is provided which passes only the range of sounds corresponding to a woman's scream, etc. through the microphone 23I/'i amplifier 28.
9, and the output of this filter 4 is connected to comparator '(9)
is applied to one input terminal of the comparator I, and a reference value Vrsf2 for setting the output level from the filter 4 is applied to the other input terminal of the comparator I. The output in between is connected to a timer 31 that sends out an output signal when a sound equivalent to a screaming pregnancy continues for a certain period of time, and the signal to the output signal of this timer 31 is output from the flip-flop 15 or 17. It is adapted to be applied to an AND gate 32 which takes the output as one input.

Moreover, the above-mentioned rejection detection sensor detects the distortion when a passenger hits the inner wall of the car with his or her hands or feet, and sends out an output signal. TomoK is applied to one input terminal of the comparator, and a reference value Vr@f3 for setting the output level of the non-detection sensor is applied to the other input terminal of the comparator. A counter is connected to the output of the counter 35, which counts the output and operates just in case the car wall is struck a predetermined number of times within a predetermined time.
Also, an AND gate % that uses the output signal of C17 as one input.
can be added to.

The outputs of the AND gates 27, 32, and 36 are OR-
It is configured to be applied to the set terminal of the flip-flop through gate 37, and the Q when set is
Outputs include a notification signal S3 to the control room in the event of an abnormality such as when a molestation occurs, and a command signal 8aK that causes the elevator to run to the nearest floor or the entrance floor (first floor) and stop. At the same time, as a means to exclude molesters, etc., for example, as an activation command for an auto-announcement device 39 that records a voice saying "What are you doing?"
The information is also provided as an operation command for the display 4 that displays the occurrence of molestation, etc. Further, the Q output of the flip-flop blade is applied to an AND gate 40 which receives the door fully open signal S2 as one input, and the output of this AND gate 40 is applied as a trigger signal to the one-shot multivibrator 41. , this multivibrator 41 sends out a door closing prevention command signal S5 corresponding to about an additional second with one trigger operation. Further, a one-shot multivibrator 42 is provided which is triggered by the falling edge of the door closing prevention command signal S5, and the output signal of this multivibrator 42 is applied to the reset end of the flip 38.

Next, the operation of the inventive device configured as described above will be explained.

First, when the 1 selection switch 16 is connected to contact a, when the time measured by the clock circuit 14 reaches the set time of the crime prevention start time setting device 10, a match signal is sent from the match circuit 12, which causes the flip-flop 15, and its Q output "H" drives the display 3.
Displays the message ``In security operation'' on passengers and sets the elevator to security operation mode. Further, when the time measured by the 1-clock circuit 14 reaches the set time of the crime prevention end time setting device 10,
A coincidence signal is sent from the coincidence circuit 13, which resets the shift flip-flop 15 and cancels the security operation mode of the elevator.

Turn off the display 3. That is, when the selection switch 16 is connected to the contact a side, the elevator is connected to the setting device i.
The crime prevention driving state will be automatically set during the time period set by o and o.

In addition, when the selection switch 16 is connected to contact b (illK), the elevator is set to the security operation state each time the elevator is used according to the demands of passengers. When you press the crime prevention driving request button 6 installed in the hall, the flip-flop 17 is set by the signal, and when this flip-flop 70 knob 17 is set, its Q output becomes H'', which causes the request button to be pressed. The built-in lamp 6a is turned on and at the same time the display 3
The elevator also lights up to display the message ``In security operation'' to indicate to customers and others that the elevator is in security operation mode.

In this state, if the passenger presses the hall call button 5, gets into the car, and then presses the car call button (not shown) for the desired floor, the elevator door will close and the car will travel to the registered floor. The running signal s1 at this time is applied to the set end of the 7-lip flop 19, thereby keeping it in the set state.

Then, when the elevator car stops at the car call registration floor and the door is fully opened, the door fully open signal is applied to the reset terminal of the flip-flop 19.
At the same time, when the flip-flop 19 is reset, K,
At this time, the one-shot multivibrator 18 is triggered by the fall of the Q output, and its output resets the shift flip-flop 17, canceling the crime prevention operation of the elevator and returning to normal operation.

Note that when the crime prevention driving is automatically set by the time setting devices 10 and 11, the operation of the crime prevention driving request button 6 is not necessary.

In addition, when the flip-flop 15 or 17 is set, when the elevator is in security operation, if a passenger in the car leans against or is pushed against the handrail 21 inside the car. , a voltage corresponding to the pressing force is generated from the pressure sensor n, and this reaches a level exceeding the reference value Vr@f of the comparator section, and when the voltage at this level continues for a certain period of time set by the timer,
It is determined that the passenger in the car has been attacked by a molester, and a signal is sent from timer 26, which is then used as an andgo)2
Add to 7. Further, when the sound corresponding to a woman's scream continues for a certain period of time, the sound is picked up by a microphone and converted into an electrical signal, and then passes through a filter 29, and a comparator and a timer 31 are activated. Then, it determines that the passenger is being attacked by a molester, etc., and sends a signal to the AND gate 32. Furthermore, when a passenger who has boarded the car hits the inner wall of the car, a voltage corresponding to the impact force is generated from the strain detection sensor U, and this is the reference value Vref of the comparator 34.
When the level exceeding 1 is exceeded, a signal is sent from the comparator and the nuclear signal is counted by the counter 35. When the inner wall of the car is tapped for a certain period of time so that the output voltage exceeding the reference value Vref is obtained from the sensor, the counter counts up and it is determined that the passenger who got into the car has been attacked by a molester. 36.

That is, if it is determined that a molestation has occurred in at least one of the detection circuit systems of the pressure sensor n, the microphone device, or the strain detection sensor 24, the Q output of the flip-flop 15 or 17 is connected to one input. Anime game
) Since the AND condition of 27, 32 or 36 is satisfied, the output becomes ``H'', which sets the shift flip-flop 38. When the flip-flop blade is set, the output Q becomes ``H''. Therefore, the Q output is applied to the auto-announcement device 39 and the display 4 as a start command, and by driving the auto-announcement device 39, a warning such as [Colan, what are you doing, stop it] is issued, and By lighting up the display 4, a display stating "molestation has occurred" is displayed in the hall, and furthermore, the occurrence of molester etc. is reported to the manager. At the same time, the Q output is transmitted to the elevator control circuit (not shown) as a stop command to the nearest floor or entrance floor, thereby automatically moving the elevator car where the molestation occurred to the nearest floor or entrance floor. The vehicle runs and stops. Eley).

When the car stops at the nearest floor or the entrance floor, the door of the car opens, and when it is fully opened, the analog game (40) which inputs this door fully open signal S2 and the Q output is activated, and its output ``H'' is activated.
"The one-shot multivibrator 41 is triggered, and the one-shot multivibrator 41 sends a door closing prevention command signal s5 to keep the car door open for about a second. Then, when the second has elapsed, , the one-shot multivibrator 42 is triggered when the one-shot multivibrator 41 falls, thereby resetting the shift flip-flop 38 and canceling the molestation detection operation mode.

Note that when the 1 selection switch 16 is connected to the flip-flop 17, the elevator is returned from crime prevention operation to normal operation at the same time as the molestation detection operation mode is canceled. Further, when the selection switch 16 is connected to the 7-lip flop 15, the molester detection operation mode is only canceled and the elevator is set to the security operation mode button.

Next, various modifications of this invention will be listed.

(,) The means for inputting requests for crime prevention driving is not limited to buttons.
Input using a special magnetic card, code input using a numeric keypad, or next input method using voice recognition may be used.Also, the destination may be entered when entering the code, and car calls may be automatically registered. A method in which the switch is turned on in a passenger room or the like may also be used.

(b) The means for detecting molestation, etc. is not limited to those shown in the examples, but may include ITV, ultrasonic cameras, optical sensors, etc. For example, when there is sudden movement in the car, a weapon such as a knife, etc. It is also possible to perform pattern recognition and detect the occurrence of a ke.

(c) Sensors installed on the handrails inside the car or on the inner walls of the car may include, in addition to those described in the examples, microswitches, switches using capacitance, etc. A switch that can be turned on with a foot may be provided, and when this is turned on, it may be determined that a molestation has occurred.

(d) To detect the voice of a woman, etc. when encountering a molestation, etc.
Instead of using a bandpass filter as in the embodiment, the scream may be recognized by voice recognition.

(@) When a molestation occurs, the molestation may be recorded with a camera or VTR, and the voice may be recorded with a tape recorder to help identify the criminal.

(f) When a molestation or the like occurs, it may be automatically reported to 110, or the molestation or the like may be confined in a cage.

(g) Door opening time when stopping at the nearest floor or entrance floor is 9
It is not limited to seconds, but may be extended to infinity and manually reset υ.

As described above, according to this invention, when crime prevention operation of an elevator is automatically commanded by the hall, control room, or clock means, a button to that effect is displayed on the hall, etc., and when a molester or the like occurs while using the elevator. In addition to taking measures to eliminate such abuse, the elevator hall, control room, etc. are notified of this, and the car is stopped at a designated floor and the elevator is placed on standby. In addition to being highly effective, it is also possible to improve the reliability of elevators for users.
