Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an elevator control device that detects the presence or absence of passengers in a car and operates the elevator when the elevator is in an abnormal state, for example, when the car stops due to a power outage. It is something.

When an elevator is in an abnormal state, for example, there is a power outage, as disclosed in Japanese Patent Publication No. 2482-2482, private power generation is generated from among multiple elevators, regardless of whether there are passengers in the car or not. The number of cars that is less than the allowable number limited by the device is selected and operated one after another to a standard floor, for example, the first floor, and the operation to release passengers trapped in the car from the car, that is, operation during power outage is adopted. As a result, the rescue of passengers was sometimes delayed due to the operation of empty cars. For this reason, it has been proposed to operate the car only when there are passengers in the car.

However, the device for detecting the presence or absence of a passenger has generally been a load detection device operated by the weight of the passenger, as disclosed in, for example, Japanese Utility Model Publication No. 13327/1983. For this reason, if luggage is left in the car, it is assumed that there are passengers even though there are no passengers, and the elevator is operated in vain.

This invention was made in view of the above-mentioned problems, and when an abnormality occurs in the elevator, a sound is sent into the car of the elevator, and as a result, when no sound is detected as a response to the above-mentioned sound, the sound is sent to the car of the elevator. The purpose of this is to prevent elevators from being operated unnecessarily when no passengers are present.

An embodiment of the present invention will be explained based on FIGS. 1, 2a, and 2b. In the figures, 1 is a computer connected to an uninterruptible power supply (not shown), and 2 is a computer connected to this computer. A central processing unit (hereinafter referred to as CPU) of an electronic computer 1, a bus line 3 consisting of an address bus, a data bus, etc. connected to this CPU 2, a bus line 4 connected to this bus line 3, 2, a storage device in which programs and data for operating the elevator are stored, as shown in FIG. This is an abnormality detection device consisting of a detection device, which inputs power outage information to the computer 1 through the converter 5b. Reference numeral 6 denotes a speech synthesis device in which predetermined speech data is stored, which is connected to the bus 3 via a converter 6a, and which transmits and receives signals to and from the computer 1 to synthesize the above-mentioned speech data. It extracts the necessary audio data from the audio, edits the audio, and plays it back. 7 is a speaker provided in the car 8 and transmits the sound reproduced by the voice synthesizer 6 to the passenger 9; 10 is provided in the car 8;
A microphone 11 converts the voice emitted by the passenger 9 into an electrical signal, which is connected to the bus 3 via a converter 11a.
A voice recognition device connected to the electronic computer 1 and controlled by sending and receiving signals to and from the computer 1 converts the electric signal from the microphone 10 into a digital signal, and converts the electrical signal from the microphone 10 into a digital signal. It compares the voice data to find a match, detects the voice uttered by the passenger 9, and recognizes the content of the voice. Reference numeral 12 denotes an elevator state detection device comprising a contact 12a that is closed when the car 8 is running, a contact 12b that is closed when the car 8 is in the door zone, and a contact 12c that is closed when the door is open. , 12d is a converter that converts the signal from the state detection device 12 into a signal from the computer 1, and 13 is connected to the bus 3 via the converter 13a to operate the elevator according to the command from the computer 1 during abnormal times. This is a power outage operation circuit which is a control circuit.

The operation of the elevator control system constructed as described above will be explained with reference to the flowcharts shown in FIGS. 2a and 2b.

First, when regular power is being supplied, no signal is output from the power failure detection device 5, so the determination in step 4a is "no" and the program waits. Meanwhile, the elevator operates normally.

If a power outage occurs, the elevator will stop at any location. Further, the power outage detection device 5 detects a power outage and inputs the detected power to the computer 1 via the converter 5b. The computer 1 detects a power outage, and the determination in step 4a is "yes", and the process proceeds to step 4b, where the computer 1 issues an operation command to the speech synthesizer 6 via the converter 6a. In response to this activation command, the voice synthesizer 6 calls out to the car 8 via the speaker 10, "Who is there?" Meanwhile, the program proceeds to step 4c and waits until the speech synthesizer 6 finishes its operation. When the speech synthesizer 6 finishes operating, a termination signal is output and input to the computer 1 via the converter 6a. When the above-mentioned end signal is input, it is judged as "yes" in step 4c and the process proceeds to step 4d, where the voice recognition device 11 receives an activation command via the converter 11a and operates, We aim to detect the voice of

Meanwhile, the program proceeds to step 4e. If no voice is detected, the determination is "no" and the process proceeds to step 4f. Until a predetermined time has elapsed, the process cycles between step 4e and step 4f and waits while checking whether or not a voice has been detected. If no voice is detected even after the predetermined time has elapsed, the process proceeds to step 4g.
If the activation command to the voice synthesizer 6 is less than the predetermined number of times, the determination is "no" and the process returns to step 4b.
The speech synthesizer 6 receives an operation command again and operates,
Call to car 8. Thereafter, the speech recognition device 11 operates as described above to detect speech.
When the above operation is repeated a predetermined number of times without detecting a voice, it is assumed that there are no passengers in the car, and the process proceeds to step 4r, in which a command is issued to disconnect the power outage operating circuit 13. The elevator will be stopped until power is restored. If a voice is detected, it is assumed that there are passengers 9, 9 in the car 8, and the process proceeds from step 4e to step 4h, and an operation command is issued to the power outage operation circuit 13 via the converter 13a. The elevator is operated by the power outage operating circuit 13 to drive the car to the nearest floor. The program proceeds to step 4i, and checks whether the car 8 is in the door zone via the contact 12b, whether the car 8 is stopped via the contact 12a, and whether the door of the car 8 is open via the contact 12c. to decide. If the contact 12a
is open and contacts 12b and 12c are not closed, step 4i
If the result is “no”, the system waits. If the contacts 12a, 12b, and 12c are in the above state, the determination is "yes" and the program is executed in step 4.
Proceed to step j and issue an operation command to the speech synthesizer 6. The voice synthesizer 6 calls out to the car 8 via the speaker 10, "Have you gotten off the car?" On the other hand, the program proceeds to step 4k and waits until the operation of the speech synthesizer 6 is completed. When the operation is completed, the program determines "yes" and proceeds to step 4l, in which an operation command is issued to the speech recognition device 11. In response to the voice synthesizer 6, the passenger 9
The determination in step 4m is "no" and the process waits until a predetermined time period, which is sufficient time for the user to make a sound, has elapsed. When the predetermined time has elapsed, the determination is "yes" and the process proceeds to step 4m. When the voice recognition device 11 detects the voice, a "yes" determination is made in the step 4n, and the program returns to the means 4j. If no voice is detected, the determination is "no" and the process proceeds to step 4p. If the processing from the means 4j to step 4n is not repeated a predetermined number of times, the determination is "no" and the process returns to step 4j. If it is repeated a predetermined number of times, it is determined as "yes". That is, it is determined that there are no passengers in the car 8, and the process proceeds to step 4b, where a command is issued to the power outage operation circuit 13 to close the door. “No” in step 4r until the door closes
It is determined that this is the case and the system waits. When the door closes, contact 12c
The computer 1 inputs that the circuit has been opened, and when it determines "yes", the process proceeds to step 4s, and a command is issued to disconnect the power outage operating circuit. This will cause the elevator to stop until power is restored.

In the above embodiment, the speech synthesis device 6
When the voice of the passenger 9 in the car 8 is detected after the voice is emitted by the car 8, operation during power outage is performed as if there is a passenger, and when no voice is detected, it is assumed that there is no passenger and operation during power outage is not performed. Even if the luggage in the car 8 is left unattended, the car 8 will not be operated in vain if there are no passengers. In addition, normally during power outage operation, elevators are operated one by one, so it takes a long time until the last passenger 9 is released from the car 8. However, according to the above implementation, the empty car 8 Passenger 9 will be left alone.
can be released from car 8 quickly.

Furthermore, when a power outage occurs, passengers tend to feel anxious, but the broadcast by the voice synthesizer 6 can give them a sense of security. For example, "There's a power outage, but don't worry. We'll be driving to the nearest floor soon, so please wait quietly."
This broadcast can ease the tension of passengers 9. This makes it possible to prevent the occurrence of secondary disasters such as falling accidents caused by forcibly trying to escape from the inside of the car 8.

In the above embodiment, the case where the application is applied to operation during a power outage has been described, but when the elevator is out of order and the car 8 stops between floors, the car 8
drive to the nearest floor. It functions similarly even when applied to so-called bottling rescue operation. That is, in FIG. 1, a conventionally known packing detection device is used in place of the power outage detection device 5 as the abnormality detection device, and a conventionally known packing detection device is used in place of the power outage operation circuit 13 as the abnormality operation circuit. By using the rescue operation circuit, it is possible to avoid unnecessary operation of a car with no passengers even if a baggage is left in the car 8.
In addition, the voice synthesizer 6 broadcasts the information to the passengers 9.
It can also provide a sense of security.

Furthermore, the earthquake operation specified by the Japan Elevator Association is generally used as an operation method when an earthquake occurs, and if an earthquake occurs while car 8 is traveling in an express zone, After the car 8 is brought to an emergency stop, the car is driven in a direction away from the counterweight to stop the car 8 at the nearest floor. In such earthquake operation, by using a seismic sensor as an abnormality detection device and an earthquake operation circuit as an abnormality control circuit, it is possible to prevent empty cars from being operated in vain, as in the above embodiment. It can be avoided. In particular, when an elevator is operated during an earthquake, if the elevator has already been damaged by the earthquake, there is a risk that the damage will be increased by operating the elevator. By avoiding operating an empty car 8 during such earthquake operation, damage to the elevator can be minimized. Further, the broadcasting of the voice synthesizer 6 can also give a sense of security to the passengers 9.

Furthermore, in the above embodiment, the voice output device is a voice synthesis device, but it is clear that it can also function as a magnetic tape device for reproducing voices recorded on a magnetic tape in the same manner as in the above embodiment.

Furthermore, in the above embodiment, the sound detection device is a sound production recognition device, but the sound pressure level is higher than a predetermined value with respect to the sound pressure level of background noise detected in the car 8 when no passenger is on board. It is clear that the present invention functions similarly to the above embodiment even if a sound pressure level detection device that operates when a level is detected is used.

As mentioned above, this invention is useful when an abnormality occurs in an elevator due to, for example, a power outage or an earthquake.
an abnormality detection device that detects this, a voice transmission device that is activated by the signal of the abnormality detection device and sends a voice to the elevator car to call out to passengers, and A voice recognition device that recognizes the voice of a passenger by detecting the voice of the passenger and comparing this detection result with pre-stored voice data, and an abnormality in which the elevator is operated based on the output signal of this voice recognition device. Since the car is equipped with a time control circuit, no sound will be detected if there are no passengers and only objects are loaded in the car. Therefore, this has the effect that an elevator without passengers will not be operated in the event of an abnormality.
