Description

  The present invention relates to elevator control technology.

  As one index indicating the quality of service in an elevator, there is a time required for a passenger (user) to start waiting for an elevator at a boarding floor and to get on the elevator and arrive at a destination floor (hereinafter, referred to as “required time”). In an elevator system in which a plurality of elevators cooperate, a plurality of elevators are integrated and managed, and efficient operation of the plurality of elevators is scheduled to reduce the time required for each passenger.

  In addition, as an index of time affecting the required time of each passenger, a time during which the elevator stops at a floor (hereinafter referred to as “intermediate floor”) that is present on the way from the passenger's boarding floor to the destination floor (hereinafter, “stop”) I have time. The stop time on the middle floor occurs because another passenger gets on the elevator or gets off the elevator on the middle floor for the passenger. If the stopping time at the middle floor can be shortened, the time required for each passenger can be shortened, and the energy efficiency of the entire elevator system can be improved. In order to reduce the stop time, it is effective to reduce the time during which the elevator door is kept open at the stop floor (hereinafter referred to as “door open time”).

  Patent Literature 1 discloses a technique for determining the timing of closing a door based on an image captured by a camera. In this technique, a moving direction of a passenger getting on and off is detected using a camera capable of photographing both the inside of an elevator car and the floor. If the passenger is moving away from the elevator, the passenger is deemed not to be riding, and the timing to close the door is advanced.

  Patent Literature 2 discloses a technique in which an elevator operating system and a weight sensor cooperate to detect various types of information in an elevator. This technique detects the presence or absence of a passenger in an elevator, the number of passengers in the elevator, and detects a rampage of the passenger in the elevator. In order to detect the getting on / off of the passenger and the presence / absence of the passenger in the elevator based on the information detected by the weight sensor, a threshold value used for determination based on the sensor data output from the weight sensor or a correction value for correcting the sensor data is calculated. Patent Document 2 also discloses using the number of objects sensed by a photoelectric (infrared) sensor as an alternative to sensor data of a weight sensor.

  FIG. 9 is an example of a flowchart for processing operation information in the analyzer 300.

  In step 901, operation information is obtained. Specifically, the observation information input unit 301 receives the observation information 450 from the elevator 200, and the operation information generation unit 302 gets on the elevator 200 based on the observation information 450 received by the observation information input unit 301. Operating information 400 including operating information for each passenger who is present.

  In step 902, user information is obtained. Specifically, the user information extraction unit 303 identifies each passenger based on the operation information for each passenger included in the operation information 400 generated in step 901. As an identification method, for example, there is a method of performing face recognition using camera information 407 included in operation information, voice recognition using microphone information 408, individual identification using weight change using weight information 409, or a combination thereof. Then, the user information extracting unit 303 searches the user information database 308 for the user information 700 corresponding to each identified passenger using the operation information for each passenger as a search key.

  In step 903, it is determined whether the passenger riding the elevator 200 is a passenger registered in the user information database 308. More specifically, the user information extraction unit 303 determines whether or not the user information 700 including the operation information 705 corresponding to the search key has been found based on the search result of step 902. The process proceeds to step 904 as a registered passenger (Yes in step 903), and if not found, proceeds to step 905 as an unregistered passenger (No in step 903).

  In step 904, the operation information is associated with the existing user information 700. Specifically, the user information extracting unit 303 stores the user information 700 as the search result in step 902 in the user information database 308 as the operation information 705 in association with the operation information used as the search key.

  In step 905, a new user is added to the user information database 308 and the operation information is associated. Specifically, the user information extraction unit 303 creates new user information 700 and stores the new user information 700 as operation information 705 in the user information database 308 in association with operation information used as a search key.

  In steps 904 and 905, after storing the user information 700 including the operation information 705 in the user information database 308, the operation information analysis unit 304 performs an operation based on the stored user information 700 and the analysis setting 600 included in the analysis setting database 307. The analysis of the passenger is performed, and the identifier 702 in the elevator of the user information 700, the tag 703 as the passenger attribute, and the status 704 are set.

  Specifically, the operation information analysis unit 304 sets a value capable of uniquely identifying a passenger who is riding in the elevator 200 in the elevator identifier 702 of the user information 700. The operation information analysis unit 304 compares the weight information (information indicating a temporal change in weight) of the operation information 705 of the user information 700 with the data 614 of the analysis data 610 and determines that the coincidence rate is equal to or more than the reference value. , The tag 613 associated with the data 614 is set as the tag 703 of the user information 700. The operation information analysis unit 304 compares the behavior of the passenger acquired based on, for example, the button information, the camera information, the microphone information, the weight information, or a combination of these pieces of information of the user information 700 with the condition 602 of the analysis setting 600 and determines the condition. If satisfied, the process associated with the condition is executed, and the status 704 and the like of the user information 700 are set. In addition, the exit floor of the passenger is predicted based on the past operation information 705 included in the user information 700 and is included in the status 704. Further, the predicted accuracy of the drop-off floor may be calculated and included in the status 704.

  FIG. 10 is an example of a flowchart of a process of creating control information of the elevator 200 in the analyzer 300.

  In step 1001, the control information calculation unit 305 creates an empty control process list that can store zero or more control processes.

  In step 1002, the control information calculation unit 305 starts the repetition processing between step 1008 and each user information 700 stored in the user information database 308.

  In step 1003, the control information calculation unit 305 determines whether or not the status 704 of the user information 700 is the exit completion, that is, whether or not the user information 700 of the passenger who does not exist in the elevator 200. If it is the user information 700 of the passenger existing in the elevator 200, the process proceeds to step 1004 (No in step 1003), and if it is the user information 700 of the passenger not existing in the elevator 200, the process proceeds to step 1008 ( Yes in step 1003).

  In step 1004, the control information calculation unit 305 starts the repetition processing with step 1007 for each control setting 800 set in the control setting database 309.

  In step 1005, the control information calculation unit 305 determines whether the condition 802 set in the control setting 800 is satisfied based on the control setting 800 and the user information 700. If satisfied, in step 1006, control processing information including the processing 803 and the priority 804 corresponding to the condition 802 is added to the control processing list created in step 1001.

  In step 1009, the control information calculation unit 305 determines whether the control processing list is empty. If the control processing list is empty, the process ends (Yes in step 1009), and if the control processing list is not empty, the process proceeds to step 1010 (No in step 1009).

  In step 1010, when one or more pieces of control processing information are set in the control processing list, the control information calculation unit 305 creates the control information 500 from the control processing information including the highest priority 804 and performs control. The information output unit 306 transmits the information to the elevator 200. The elevator 200 operates the driving device 207 such as the door 215 and the motor 216 based on the control information 500.

Specifically, the user information console 1100 includes an operation information list 1101, a data selection button 1102, user information 1103, sensor / user interface information 1104, a play button 1105, and a seek bar 1106.

  For example, as in the example of FIG. 11, in the operation information list 1101, an excerpt of the operation information for each user included in the operation information 400 is displayed, and specific operation information is selected and the data selection button 1102 is operated. By clicking (for example, selecting with a mouse and clicking), information on the user related to the selected operation information is displayed in the user information 1103 and the sensor / user interface information 1104.

  An excerpt of the user information 700 is displayed in the user information 1103, and each data item can be changed by means of selection from a list or direct input.

  The sensor / user interface information 1104 includes, for example, an image captured by the camera 211 and a temporal change in the weight of the elevator 200 measured by the weight sensor 212, an operation state of the button 213, and an input to the microphone 214. The information of the sensor and the user interface such as a voice waveform is displayed, and the information can be confirmed. In addition, the user's tag (passenger attribute) estimated by analyzing the information and the estimation accuracy are displayed. Further, by using the play button 1105 and the seek bar 1106 for displaying a playback position, each piece of information can be displayed for each time, and a change in the information over time can be confirmed.

  As described above, according to the elevator system of the present embodiment, the analyzer 300 identifies the passenger based on the observation information 450 output by the elevator 200, and the operation information 400 including the operation information in which the observation information 450 is grouped for each passenger. Generate The operation information for each passenger is included in the user information 700 on the passenger and stored in the user information database 308. The attribute of the passenger estimated based on the operation information for each passenger is included in the user information 700 regarding the passenger as a tag 703 and stored in the user information database 308. If the user information 700 regarding the passenger identified based on the new observation information 450 is already stored in the user information database 308, the control information 500 is generated based on the tag 703 included in the user information 700 and output to the elevator 200. I do. Because of this, the attributes of the passengers of the elevator 200 are estimated, the tag 703 indicating the attribute is stored in the user information database 308, and the tag 703 based on the passenger tags stored in the user information database 308 is stored. Thus, the elevator 200 can be controlled. As a result, it is possible to perform advanced elevator control according to the attributes of the passenger.

  In addition, the elevator 200 includes a sensor 205 including a camera 211 that captures an image in the elevator 200, and outputs an image captured by the camera 211 as observation information 450. The analysis device 300 identifies the passenger of the elevator 200 based on the image included in the observation information 450, estimates the passenger status indicating the behavior state of the passenger, sets the status as the status 704 in the user information 700, and sets the user related to the passenger. The control information 500 is generated based on the tag 703 and the status 704 of the information 700. By doing so, the control is determined based on the combination of the passenger's attribute and the behavioral state, so that suitable control can be performed according to the passenger's state and attribute.

  In addition, the elevator 200 includes a sensor 205 including a weight sensor 212 that measures a temporal change in the weight of the elevator 200, outputs the temporal change in the weight as the observation information 450, and the analyzer 300 determines the type 612 indicating the attribute of the passenger. Analysis data 610 is stored in advance in which data 614 indicating a typical time change of weight when a passenger having the attribute indicated by the type 612 enters the elevator 200 is stored in advance, and the time change of the measured weight is stored. Based on the data 614 of the analysis data 610, the passenger attribute of the passenger who has entered the elevator 200 may be estimated. By doing so, it is possible to satisfactorily estimate the attributes of the passenger exhibiting characteristic weight fluctuations.

  In addition, the analysis device 300 stores in advance a control setting 800 in which a condition 802 which is a condition relating to a passenger, a process 803 to be executed when the condition is satisfied, and a priority 804 of the process are associated. . Then, when each of the plurality of passengers identified based on the new observation information 450 satisfies the condition 802 of the control setting 800, the process 803 in which the highest priority 804 is satisfied among the satisfied conditions 802 is executed. The control information 500 for making it perform is generated. With this configuration, when there are a plurality of control processes to be performed on the passengers of the elevator 200, the control process with the higher priority is performed. Therefore, a configuration in which a suitable process is selected and performed when there are a plurality of passengers is configured. Can be easily realized.

  Note that the priority 804 is omitted from the control setting 800, and the control setting 800 in which the condition 802, which is a condition relating to a passenger, and the process 803 to be executed when the condition is satisfied is stored in advance, and a new setting is stored. When the passenger identified based on the detailed observation information 450 satisfies the condition 802 of the control setting 800, the control information 500 for executing the process 803 associated with the satisfied condition 802 may be generated. By doing so, the control information 500 can be generated by a simple process when there is no need to consider the priority for each passenger attribute.

  The condition 802 of the control setting 800 includes a passenger attribute and a passenger status indicating a behavior state of the passenger, and the process 803 is a process of setting a door opening time according to the passenger attribute. In this way, the control setting 800 in which the passenger attribute and the door opening time are associated with each other is stored in advance, and when the passenger gets off the vehicle, the door is continuously opened for the door opening time according to the attribute of the passenger. Therefore, the door can be opened for an appropriate time according to the attributes of the passenger.

  In addition, the elevator 200 includes a camera 311 that captures an image of the inside of the elevator 200 and a sensor 205 including a weight sensor 212 that measures the weight of the inside of the elevator 200, and includes a microphone 214 that obtains a sound in the elevator 200, The image, weight, and sound are output as observation information 450. The analyzer 300 identifies the passenger by using a combination of at least two of the image, weight, and audio information included in the observation information 450, and transmits the operation information including the image, the weight, and the audio information to the passenger. The information may be included in the user information 700 about the passenger and stored in the user information database 308. By doing so, the passengers are identified based on any combination of the image, weight fluctuation, and audio by the camera, and therefore the passengers can be identified well.

  Further, the analyzer 300 associates the user 701 included in the user information 700 with the tag 703 indicating the passenger attribute on the user information console 1100 which is an operator screen, and sets and changes the tag 703 for the user 701. Displayed as acceptable. By doing so, it is possible to easily confirm and change the association between the user 701 and the tag 703 included in the user information 700.

  The elevator 200 includes a sensor 205 including a camera 211 that captures an image in the elevator 200, and outputs the image as observation information 450. The analysis device 300 stores the operation information including the image in the user information database 308 by including it in the user information 700, and displays the image included in the user information 700 on the user information console 1100. By doing so, the user information 700 can be confirmed based on the image.

  Next, an elevator system 100A according to a modified example in which a part of the configuration of the above-described embodiment is changed will be described. This elevator system 100A includes the elevator 200 and the analyzer 300 described above, and has control settings shown in FIG. 12 instead of the control settings shown in FIG. The elevator system 100 </ b> A is such that a passenger who gets on the vehicle automatically conveys to a desired exit floor without operating the button 213.

  FIG. 12 shows an example of a control setting 1200 used in place of the control setting 800.

  The control setting 1200 is composed of one or more data tables (in this embodiment, one row is one data table and a total of five data tables).

  As shown in FIG. 12, in the control setting 1200, similarly to the control setting 800, an identifier, a condition, a process, and a priority are associated with each other, and these constitute a data table.

  The table 1201 is set with control for reproducing guidance voice for passengers (users) whose landing floor is unknown or whose prediction accuracy is less than 90%.

  In the table 1202, the control when the passenger inputs the disembarkation floor by voice is set.

  The table 1203 is set with a control for automatically inputting the exit floor without waiting for the passenger to operate the button 213 if the predicted accuracy of the exit floor of the passenger is 90% or more.

  The table 1204 is set with control when a passenger utters a voice to open the door.

  The table 1205 is set with control when a passenger utters a voice to close the door.

  For example, the processing of the table 1204 and the processing of the table 1205 are contradictory, but since the priority is set, if both conditions are satisfied, only the processing of the table 1204 having the higher priority is executed.

  The elevator system 100A identifies the passengers who have boarded the elevator 200, and predicts the exit floor for each identified passenger and automatically carries the passenger to the predicted exit floor. Specifically, for the passenger identified on the basis of the observation information 450, the analyzer 300 aggregates information about the past exit floor from the operation information 705 of the user information 700 on the passenger, and predicts the exit floor, The prediction accuracy is calculated. And the control information 500 for carrying a passenger to the said getting-off floor is produced | generated. For example, if a passenger has got off only on the first floor and the tenth floor in the past and gets on from the first floor this time, the tenth floor is predicted as the getting off floor, and the prediction accuracy is set to 100%. Or, if the passenger has previously got off 70 times on the 10th floor and got off 30 times on the 9th floor and got on from the 1st floor this time, the 10th floor is predicted as the getting off floor, and the prediction accuracy is 70 %.

  Then, based on the control setting 1200, for example, when the passenger's drop-off floor cannot be predicted, or when the passenger's drop-off floor is predicted but the prediction accuracy is less than 90%, the user is prompted to input the drop-off floor to the button 213. The control information 500 for reproducing the guidance voice is generated.

  Alternatively, when the passenger utters a voice designating the disembarkation floor, the floor indicated in the voice is set as the disembarkation floor, the prediction accuracy is set to 100%, and control information 500 for transporting the passenger to the predicted disembarkation floor is generated.

  Alternatively, when the predicted accuracy of the passenger drop-off floor is 90% or more, the control information 500 for transporting the passenger to the predicted drop-off floor is generated.

  Alternatively, when the passenger utters a voice for opening the door, control information 500 for setting the door open time to 5.0 seconds is generated.

  Alternatively, when the passenger utters a voice for closing the door, the control information 500 for setting the door open time to 0.0 seconds is generated.

  Then, the control information 500 generated by the analyzer 300 is transmitted to the elevator 200. When a plurality of pieces of control information 500 are generated at the same time, the control information 500 having the highest priority is transmitted to the elevator 200.

  The analyzer 300 of the elevator system 100A creates operation information including information indicating the floor at which the passenger got off from the observation information 450 output by the elevator 200, and includes this operation information in the user information 700 relating to the passenger and the user information. Store and accumulate in the database 308. Then, the analyzer 300 predicts the exit floor at which the passenger identified from the new observation information 450 will get off based on the user information 700 stored in the user information database 308, and control information for stopping at the predicted exit floor. Generate Thus, since the control information for predicting the passenger's disembarkation floor from the past disembarkation floor of the identified passenger and stopping to the disembarkation floor is generated, the stop floor according to the passenger can be automatically set.

  In addition, the analysis device 300 calculates the prediction accuracy when predicting the passenger's drop-off floor, and generates a guidance voice that prompts the passenger to input the drop-off floor if the prediction accuracy is lower than a predetermined threshold. Generate control information. Thereby, when the prediction accuracy of the landing floor is low, it is possible to urge the passenger to input the landing floor, so that it is possible to reliably stop at the appropriate landing floor.
