FIG. 2 is a diagram illustrating an example of hardware resources of the elevator control device 100 according to the first embodiment. 3 and 4 are operation flowcharts showing the operation of the elevator control apparatus 100 according to the first embodiment.

First, the configuration of the elevator control device 100 shown in the present embodiment will be described. In FIG. 1, an elevator control device 100 is connected to an elevator car 200 that carries passengers and a plurality of landings 300 that are places where the elevator car 200 is stopped and the passengers are waiting.
In each hall 300, a hall camera 310, a hall speaker 320, a hall microphone 330, and a hall monitor 340 are installed. The hall camera 310 is a camera that captures the situation of the hall as a video or an image. For example, the hall camera 310 is provided on the upper part of the elevator door, and can photograph a person on the hall. The video taken by the hall camera 310 is input to the elevator control device 100 as a hall video. The hall speaker 320 is a device that outputs sound from the elevator control device, and outputs, for example, sound input (recorded) in an elevator car 200 described later. The hall microphone 330 is a device for inputting (recording) voice or the like. For example, the hall microphone 330 inputs voice of a person 390 at the hall 300. The hall monitor 340 is an output device that displays video and images, and displays video of passengers 290 in the elevator car 200, for example.

  In the elevator car 200, an in-car monitoring camera 210, an in-car speaker 220, an in-car microphone 230, an in-car monitor 240, a car button 250, and a scale device 260 are installed. The in-car monitoring camera 210 is a camera that captures the situation in the elevator car 200 as a video or an image. The video taken by the car monitoring camera 210 is input to the elevator control apparatus 100 as a car video. The car speaker 220 is a device that outputs sound or the like from the elevator control device 100, and outputs sound or the like input by the hall microphone 330 installed in the above-described hall 300 through the elevator control device 100, for example. The in-car microphone 230 is a device that inputs (records) voices and the like in the elevator car 200, and inputs, for example, voices of passengers in the elevator car 200 and outputs them to the elevator control device 100. The in-car monitor 240 is a device that displays video and images, and displays, for example, a landing video taken by the landing camera 310. The car button 250 is a destination button for inputting a signal for instructing a destination where the passenger 290 in the elevator car 200 travels the elevator car 200, and an open / close button for instructing opening / closing of the door of the elevator In addition, when an abnormality occurs in the elevator car, an input device is provided with a contact button or the like for a passenger in the elevator car to notify the outside of the abnormality. The scale device 260 detects the load (for example, passenger weight: hereinafter referred to as passenger weight) of the passenger 290 who gets on the elevator car 200, and inputs the detected load (passenger weight) to the elevator control device 100. The scale device 260 detects the load when the passenger 290 gets on the elevator car 200, and stores the boarding floor indicating the landing 300 and the load (passenger weight) when the load is detected.

The elevator control device 100 includes a car passenger abnormality detection unit 120, a landing person detection unit 130, a car operation unit 140, and a video / audio control unit 150.
The in-car passenger abnormality detection unit 120 detects a passenger abnormality (for example, the fall of a suddenly ill person or a suspicious person) generated in the elevator car 200 based on signals from the in-car monitoring camera 210, the car button 250, and the scale device 260. When the occurrence of an abnormality is detected, a passenger abnormality signal indicating that an abnormality has occurred in the passenger in the elevator car 200 is output. The in-car passenger abnormality detection unit 120 may detect an abnormality of the passenger from the in-car voice input by the in-car microphone 230. For example, the car interior microphone 230 inputs loud voices, crying voices of children, voices calling for help, etc., and the passenger anomaly detection unit 120 analyzes the voice in the car and an abnormality occurs in the passengers. May be output.

  As a method for detecting an abnormality of a passenger that has occurred in the elevator car 200, for example, there are the following methods. Image analysis of the acquired in-car image is performed, and it is checked whether a person has fallen by performing pattern matching. The movement of a specific part (face or hand) is tracked, and if the movement is fast, it is determined that the suspicious person is rampant. Further, when the passenger weight measured by the scale device 260 is smaller than a predetermined value, it is determined that the infant is a single passenger of the infant left behind in the elevator by mistake.

  The landing person detection unit 130 acquires a landing video from the landing camera 310 and determines whether there is a person on the landing from the acquired landing video. When it is determined that there is a person at the hall, a specific hall signal indicating the hall where it is determined that there is a person is output. As a method of determining the presence or absence of a person, the front and back of the acquired hall image are compared, and if there are many different parts compared to the image at normal time (no people on the hall), it is determined that there are passengers There is a method and a method of detecting a person by image analysis and pattern matching.

  The hall person detection unit 130 acquires hall images of each hall from the hall cameras 310 installed at a plurality of halls 300 and detects the presence or absence of a person 390 at each hall 300. When it is detected that a person 390 is present at a plurality of halls, the hall 300 closest to the current position of the traveling elevator car 200 is selected from the halls determined to have the person 390, and the selected hall 300 is selected. The specific hall signal shown is output.

The car operation unit 140 controls the traveling of the elevator car 200 and the opening and closing of the elevator doors. Moreover, the car driving | operation part 140 controls the elevator car 200 as follows, for example.
When the car operation unit 140 acquires only the passenger abnormality signal output from the passenger abnormality detection unit 120 in the car and cannot acquire the specific landing signal of the landing person detection unit 130, it indicates that there is no person at any landing. As shown, the main floor (for example, the first floor where many people go in and out) is set as the return floor (the floor on which the elevator car is intended to travel, an example of a predetermined floor), and the elevator car 200 is driven on the return floor. Let the door open.

  The car operation unit 140 has acquired a passenger abnormality signal indicating that an abnormality has occurred in the passenger output from the passenger abnormality detection unit 120 in the car and a specific hall signal indicating the hall where the person is present output from the hall person detection unit 130. In this case, the elevator car 200 is caused to travel to the specific floor with the hall indicated by the specific hall signal as the specific floor. When the elevator car 200 arrives at a specific floor, the elevator door is opened on the specific floor to be on standby (door open standby). When the elevator car 200 waits for the door to open, the person 390 at the hall 300 can rescue passengers in the car.

When the car driving unit 140 travels the elevator car 200 to a specific floor and then determines by a predetermined means that the person 390 of the hall 300 has boarded on the specific floor, the return floor that is the destination of the elevator car 200 Is the main floor and the elevator car 200 is driven to the return floor. When the elevator car 200 arrives at the return floor, the elevator car 200 is made to stand open on the return floor. After confirming that the passenger of the elevator car 200 has got off with the rescuer, the vehicle returns to normal operation.
The predetermined means for determining that the person on the boarding place on the specific floor is, for example, a means for detecting and determining that the weight of the passenger has increased from the predetermined weight by the scale device 260, or a video in the car. There are means for confirming passenger boarding by image analysis, and means for judging by a passenger pressing a button for closing the door.

  The video / audio control unit 150 controls the hall video captured by the hall camera 310, the car audio input by the car microphone 230, and the like. For example, when an abnormality occurs in a passenger in the elevator car 200, the video and audio of the hall and the car can be interconnected so that the person 390 in the hall 300 and the passenger in the elevator car 200 can communicate with each other by video or audio. Like that.

  The video / audio control unit 150 includes a first video / audio control unit 151, a second video / audio control unit 152, a third video / audio control unit 153, a fourth video / audio control unit 154, a fifth video / audio control unit 155, and a sixth video. A voice control unit 156 is included.

  The first video / audio control unit 151 obtains an in-car image taken by the in-car monitoring camera 210 when the car operation unit 140 specifies a specific floor, and is installed on the specific floor and displays the video. In 340, the acquired in-car image is output.

  When the car operation unit 140 specifies a specific floor, the second video / audio control unit 152 acquires the hall image captured by the specified hall camera 310 on the specific floor as the specific hall image and puts it in the elevator car 200. The acquired specific hall image is output to the in-car monitor 240 that is installed and displays the image.

  When the car operation unit 140 identifies a specific floor, the third video / audio control unit 153 obtains the in-car audio input from the in-car microphone 230 that is installed in the elevator car 200 and inputs the sound. The acquired in-car audio is output to the hall speaker 320 installed on the specific floor and outputting the audio.

  When the car operation unit 140 specifies a specific floor, the fourth video / audio control unit 154 acquires the hall audio input by the hall microphone 330 that is installed on the specified specific floor and inputs the audio, and the elevator car 200 The hall voice is output to the car speaker 220 that is installed inside and outputs the voice.

  When the car operation unit 140 specifies a specific floor, the fifth video / audio control unit 155 outputs a predetermined audio signal indicating an abnormality of the passenger to the hall speaker 320 installed on the specified specific floor and outputting sound. . The predetermined audio signal is an audio signal stored in advance in the elevator control device 100. For example, an audio signal indicating that an emergency has occurred: “An emergency has occurred. A suddenly ill person arrives at this landing.” The predetermined audio signal may be a simple warning sound. The fifth video / audio control unit outputs a predetermined audio signal from the hall speaker 320, thereby making a voice announcement to the person 390 of the hall 300 on the specific floor and notifying that an emergency has occurred.

  When the car operation unit 140 specifies a specific floor, the sixth video / audio control unit 156 displays a predetermined abnormality indicating an abnormality of the passenger 290 in the elevator car 200 on the hall monitor 340 installed on the specified specific floor and displaying an image. Video signal is output. The predetermined video signal is a video signal stored in the elevator control device 100 in advance. For example, the text information “emergency occurred” is displayed on the hall monitor 340 and the person 390 in the hall 300 on the specific floor is displayed. Announce that an emergency has occurred.

<In-car passenger abnormality detection process Step S101 to Step S107>
First, the passenger in-car abnormality detection process until it is determined whether or not an abnormality has occurred in the passenger 290 in the elevator car 200 will be described.
In step S101, the car operation unit 140 of the elevator control apparatus 100 acquires a car call signal and detects whether or not the car call is running. When it is detected that the car operation unit 140 is traveling with a car call (in the case of Yes), the process proceeds to step S102. If there is no car call (in the case of No), the process returns to step S101.

  In step S <b> 102, the in-car passenger abnormality detection unit 120 acquires an in-car image from the in-car monitoring camera 210 installed in the elevator car 200. Further, the scale device 260 measures the weight of the passenger 290 in the elevator car 200, and the passenger abnormality detecting unit 120 in the car acquires the measured weight of the passenger. When the scale device 260 stores the landing 300 that was stopped when the weight of the passenger was measured, the passenger abnormality detection unit 120 in the car acquires the landing as the boarding floor on which the passenger got.

  In step S <b> 103, the passenger abnormality detection unit 120 in the elevator control device 100 determines whether the in-car monitoring camera 210 installed in the elevator car 200 has detected a sudden fall of a sick person or a suspicious person. To do. That is, the in-car passenger abnormality detection unit 120 determines whether an abnormality has occurred in the passengers in the elevator car 200 using the in-car image acquired from the in-car monitoring camera 210. When it is determined that an abnormality has occurred in the passenger 290 (in the case of Yes), the process proceeds to step S104. At this time, the passenger abnormality detection unit 120 in the car outputs a passenger abnormality signal indicating that a passenger abnormality has occurred. When it is determined that no abnormality has occurred in the passenger 290 (in the case of No), the process proceeds to step S105.

  In step S <b> 104, the car operation unit 140 sets a return floor serving as a landing on which the elevator car 200 travels as the main floor. The reason for setting the floor on the main floor is that if the patient is suddenly ill, it can be smoothly transported to the hospital. In addition, since a suspicious person has many people coming and going, there is a high probability that the victim will be rescued and the suspicious person will be protected. After the return floor is set as the main floor, the process proceeds to step S107.

  In step S <b> 105, the passenger abnormality detection unit 120 in the car determines whether the single passenger of the infant has been detected using the weight of the passenger measured by the scale device 260 and the in-car image taken by the in-car monitoring camera 210. To do. For example, when the weight of the passenger measured by the scale device 260 is equal to or less than a predetermined value, the passenger 290 determines that the passenger 290 is an infant. If the infant's single rider is not detected (No), it is determined that no abnormality has occurred in the passenger 290, and the process returns to S101. If an infant single rider is detected (Yes), the process proceeds to step S106. Similar to step S103, the in-car passenger abnormality detection unit 120 outputs an in-car passenger abnormality signal.

  If the passenger abnormality detection unit 120 in the car detects a single-seat infant, it is highly likely that the infant has left the parent and accidentally got on the elevator. Therefore, in step S106, the car operation unit 140 sets the return floor to the boarding floor stored in the scale device 260. After the car operation unit 140 sets the return floor as the boarding floor, the process proceeds to step S107. When the boarding floor is unknown, the car driving unit 140 may set the return floor as the main floor.

  In step S107, the car operation unit 140 cancels the car call in order to stop in an emergency. This is because the elevator car 200 is dispatched quickly to the set landing.

<People Detection Process Step S108 to Step S109>
Next, a description will be given of a landing person detection process for determining whether or not there is a person at each landing when an abnormality occurs in the passenger 290 in the elevator car 200.

In step S <b> 108, the hall person detection unit 130 acquires a hall image from the hall camera 310 installed at each hall.
In step S109 shown in FIG. 4, the presence / absence of a person in the hall 300 to be rescued from the hall camera 310 installed in each hall 300 is confirmed. That is, the hall person detection unit 130 detects (determines) whether or not there is a person 390 at each hall 300 from the obtained hall video. When the boarding person detection unit 130 detects that there is no person 390 at any boarding (in the case of No), the process proceeds to S115. When it is detected that there is a person at a certain hall 300 (in the case of Yes), a specific hall signal indicating the hall where it is determined that there is a person at the hall is output. When there are a plurality of halls 300 that are determined to have a person in the hall 300, the hall 300 that is closest to the current position (the hall) where the elevator car 200 exists is selected from the halls that are determined to have the person 390. The specific hall signal indicating the boarding place 300 is output.
The car driving unit 140 specifies the hall 300 indicated by the specific hall signal as a specific floor on which the elevator car 200 travels (distributes). After specifying a specific floor, the process proceeds to step S110.

<Video and Audio Interconnection Processing Steps S110 to S111>
In step S110, the fifth video / audio control unit 155 of the video / audio control unit 150 outputs a predetermined audio signal to the landing speaker 320 to the nearest hall (specific floor) that has been determined to have a person, so that the specific floor is set. Announcing that a person 390 has an emergency or being rescued. In step S110, the sixth video / audio control unit 156 may display a predetermined video informing that the emergency has occurred on the hall monitor 340 on the specific floor. After announcing an emergency in the elevator car 200 to a specific floor, the process proceeds to step S111.

In step S111, the video / audio control unit 150 uses the in-car monitoring camera 210, the hall monitor 340, and the like to interconnect each other so that audio and video between the elevator car 200 and a specific floor can be input and output. The situation inside can be monitored.
More specifically, the first video / audio control unit 151 of the video / audio control unit 150 connects the in-car monitoring camera 210 and the hall monitor 340 on a specific floor, and the in-car monitoring camera 210 is photographing. The video is output to the hall monitor 340. The second video / audio control unit 152 of the video / audio control unit 150 acquires the hall image captured by the hall camera 310 on the specific floor as the specific hall image and outputs the specific hall image to the in-car monitor 240. The third video / audio control unit 153 of the video / audio control unit 150 acquires the in-car audio input by the in-car microphone 230 in the elevator car 200 and outputs it to the hall speaker 320 on the specific floor. The fourth video / audio control unit 154 of the video / audio control unit 150 acquires the hall audio input by the hall microphone 330 on the specific floor, and outputs the hall audio to the car speaker 220 in the elevator car 200. After the video / audio control unit 150 connects the video and audio of the specific floor and the elevator car 200 to each other, the process proceeds to step S112.

  The video / audio control unit 150 is preferably connected so that video and audio can be input and output between the elevator car 200 and the hall on the specific floor, but outputs video and audio from the elevator car 200 to the hall on the specific floor. It may be one-way. You may only output a video and an audio | voice to the elevator car 200 from the landing of a specific floor. Further, either video or audio may be output.

<Elevator car travel processing steps S112 to S113>
In step S112, the car operation unit 140 causes the elevator car 200 to travel (distribute) to a specific floor. When the elevator car 200 arrives at the specific floor, the process proceeds to the next step S113.
In step S113, after confirming that the elevator car 200 has arrived at a specific floor, the car operation unit 140 opens the door of the elevator and causes the elevator car 200 to wait. The person 390 on the specific floor gets into the elevator car 200 and rescues the passenger 290 in which an abnormality has occurred.

<Person ride confirmation process Step S114>
In step S114, the car operation unit 140 determines whether or not the person 390 at the hall 300 on the specific floor has entered the elevator car 200 according to a predetermined procedure. The predetermined procedure for the determination may be a procedure in which the person 390 who enters the vehicle pushes down the door closing button that closes the door of the car button 250. The scale device 260 may measure the weight in the elevator car 200 and determine that it has entered. When the car driving unit 140 determines that the person 390 has boarded (boarded) (in the case of Yes), the process proceeds to the next step S117. If it is determined that the person 390 has not boarded (No), the process proceeds to step S119. The case where it is determined that the person 390 has not boarded is, for example, the case where the person 390 takes the passenger 290 out of the elevator car 200 and rescues it.

<Return Floor Contact Processing Step S115 to Step S116>
In step S115, if the hall person detection unit 130 determines that there is no person 390 in any hall 300, it is useless to dispatch or stop at another hall in order to seek rescue. The elevator car 200 is driven (allocated) to the return floor. On the return floor, the video / audio control unit 150 announces that there is an emergency in the elevator car 200 to the return floor set in advance so that a response can be taken as soon as possible. The fifth video / audio control unit 155 outputs a predetermined audio signal to the hall speaker 320 installed on the return floor. The sixth video / audio control unit 156 may output a predetermined video to the landing floor hall monitor 340.
