An elevator refers to a permanent transport device serving a number of specific floors within a building with its car running in at least two columns of rigid rails running perpendicular to the horizontal or inclined at an angle of less than 15 ° to the plumb line. The use frequency of elevators is higher and higher in our daily work and life, and particularly in high-rise buildings, the elevator is the only tool for going upstairs and downstairs. People can call the elevator to run to the waiting floor through the button of the calling device of the elevator door. After entering the elevator, the passenger can designate the elevator to run to the destination floor through the calling equipment in the elevator car, but if the passenger forgets to use the equipment in the elevator car to designate the elevator to run to the destination floor after entering the elevator and no floor selection prompt exists in the elevator car, the elevator cannot identify the destination floor of the passenger. Elevators often wait on a floor due to preset mechanisms, thereby delaying passenger time, and also occupying limited space of the elevator, increasing elevator run time and energy consumption.
Therefore, the application provides a reminding method and a reminding system for elevator calling in a car, which are characterized in that real-time images in the car are acquired, then identification and detection are carried out on the real-time images, elevator calling information of one or more passengers in the real-time images is acquired, then whether elevator calling operation is carried out on the one or more passengers within preset time is judged according to the elevator calling information, and if the elevator calling operation is not carried out on the passengers, reminding is sent to the passengers. By the method, passengers who do not call the elevator within the preset time can be reminded to call the elevator, so that time waste caused by forgetting to call the elevator by the passengers is avoided, limited space of the elevator is also avoided, and the running time and energy consumption of the elevator are reduced.
Referring to fig. 1, in an embodiment of the present invention, there is provided an elevator including an image capturing apparatus 101, an acousto-optic apparatus 102, a car 103, an inward calling apparatus 104, a car door 105, and a server 106. The image capturing device 101 may be disposed on top of the car 103, and is configured to capture a real-time image of the car 103 and transmit the real-time image to a remote server for further data processing. The acousto-optic device 102 may also be provided on top of the inside of the car 103 or at any position inside the car 103 that is easily observed by the passengers, for alerting passengers who have not performed a elevator call for a preset time. An elevator call apparatus 104 is provided in the car 103 for designating an elevator to travel to a destination floor. The image capturing device 101 may monitor the area of the call device 104 to confirm whether the passenger performs a call operation, or may install a sensor in the area of the call device 104, and detect whether the passenger performs a call operation through the sensor. The car door 105 is connected to a remote server 106 through a bus module, and the server 106 can acquire the open/close state of the car door 105. It should be noted that in the embodiments of the present application, only a part of the modules of the elevator is given by way of example, and the elevator may also include other components included in other existing elevator devices to implement the corresponding functions, which are not limited in particular.
Based on the elevator shown in fig. 1, as shown in fig. 2, the present embodiment provides a reminding method for elevator calling in a car, including but not limited to steps S201, S202, S203 and S204:
s201, acquiring a real-time image in the car.
The real-time image in step S201 includes an image of the passenger in the car 103, image information of the area of the call device 104, and time information corresponding to the real-time image. The passenger image in the real-time image and the image information of the region of the recall device 104 can be obtained by shooting through the image capturing device 101. It will be appreciated that the image information of the area of the recall device 104 is used to determine whether a passenger has performed a recall operation. When there are many passengers, a blocking situation may occur, thereby affecting the operation of the image capturing apparatus 101. Accordingly, a sensor may be installed in the area of the recall device 104 to detect whether a passenger has performed a recall operation, thereby better replacing the image capture device 101 for operation.
S202, identifying and detecting the real-time images, and acquiring elevator calling information of one or more passengers in the real-time images.
In step S202, the call information includes face image information, which can be identified and classified from real-time images obtained from the image capturing device 101 by methods such as RCNN, fastRCNN and YOLO (You Only Look Once), and the positions of the face, the human body, and the call device 104 in the car 103 are marked and classified into corresponding groups. The generic name of R-CNN is Region-CNN, which is the first algorithm to successfully apply deep learning to target detection. The R-CNN is based on algorithms such as Convolutional Neural Network (CNN), linear regression, support Vector Machine (SVM) and the like, and the target detection technology is realized. FastRCNN, YOLO and R-CNN are both one of the target detection models, and a convolution layer can be used to extract image features as well, and a full-link layer can be used to predict image position and class probability values. Specifically, the elevator taking analysis model is built on a remote server by using methods such as RCNN, fastRCNN and YOLO, and the image capturing device 101 transmits real-time images in the car 103 in real time. The elevator taking analysis model on the remote server receives the real-time image and marks and classifies the human body, the human face and the call-in equipment 104 in the real-time image, thereby obtaining the human face image information in the car.
In step S202, the call information further includes a call state, and the call state may be identified from the real-time image obtained by the image capturing apparatus 101 by methods such as CPM (Convolutional Pose Machine), hourgals, CPN (Cascaded Pyramid Network), and the like. CPM, hourgalss and CPN are both one of the gesture estimation models, and the gesture estimation problem is to determine the azimuth direction of a certain three-dimensional target object, and the method has application in many fields such as robot vision, motion tracking, single camera calibration, and the like, and can be used for identifying the elevator calling state of passengers in the application. Specifically, a real-time image obtained from the image capturing apparatus 101 is marked, resulting in a punctuation map of the real-time image. Then, the joints of the wrist of the human body are marked, and the coordinates (x, y) of the joints of the wrist of the human body are obtained. By calculating whether the human wrist joint point coordinates (x, y) in each frame punctuation chart fall in the calling equipment area A, whether the passengers have calling elevator operation or not can be judged. If the coordinates (x, y) of the wrist joint point of the human body are in the area A of the internal calling equipment, judging that the calling state is called; if the coordinates (x, y) of the wrist joint point of the human body do not fall in the area A of the calling equipment, judging that the calling state is a calling state. It will be appreciated that the coordinates (x, y) of the wrist of the human body are a subset of the coordinates of the skeletal joints, and in practical situations, there are situations where the passenger does not touch the recall device 104 with his or her hands, and those skilled in the art can replace the coordinates (x, y) of the wrist of the human body with the coordinates of other skeletal joints according to practical situations, so as to better meet the practical requirements.
In step S202, the elevator call information further includes an elevator taking time, which can be calculated from the current time obtained from the image capturing apparatus 101 and the passenger entering elevator time. The real-time image includes an image of the passenger, image information of the region of the recall device 104, and time information corresponding to the real-time image. It will be appreciated that different passengers correspond to different boarding times. Specifically, when the remote server detects that the car door is changed from the door-open state to the door-closed state through the bus, the image capturing device 101 is controlled to acquire a real-time image, the passenger-elevator analysis model marks face image information in the real-time image and the current time, such as passenger a, passenger b, passenger c, and the like, and acquires the current time, such as 13:45, record passenger a, passenger b, and passenger c, respectively, as passenger a, passenger b, and passenger c are at t1=13: 45 into the elevator. And then when the remote server detects that the car door is changed from the door-closed state to the door-open state through the bus, the image capturing device 101 is controlled to pause the acquisition of the real-time image, thereby reducing the energy consumption. Then, when the remote server detects the transition of the car door from the door-open state to the door-closed state again through the bus, then, the image capturing apparatus 101 acquires a real-time image, marks and records the passenger a, passenger c, and passenger d and acquires the current time t2 as in 13:47. passenger a, passenger b, passenger c, and passenger d are recorded, respectively. Because passenger b is not detected for the second time, the server determines that passenger b has arrived at the specified floor and left the elevator, and that the boarding time for passenger a and passenger c is t2-t1, i.e., that the boarding time for passenger a and passenger c is 2 minutes, and that passenger d is the first time to enter the elevator, then record that passenger d is at t2=13: and 47 into the elevator.
S203, judging whether one or more passengers perform elevator calling operation within a preset time according to elevator calling information.
In step S203, it is necessary to determine the elevator calling state and the elevator taking time of each passenger, that is, whether the elevator calling state is an unhooked state or not, and whether the elevator taking time is longer than a preset time. If the elevator calling state is the elevator calling state and the elevator taking time is longer than the preset time, judging that the passengers do not call an elevator in the preset time. The preset time is related to the running speed of the elevator, the density of people flow, the stopping times and other factors, and can be set by a person skilled in the art according to specific situations. For example, assuming that the preset time is 1 minute, that is, more than 1 minute, the passenger is determined that the elevator calling operation is not performed within the preset time, and the passenger is reminded. When the remote server detects that the car door 105 is changed from the door open state to the door closed state through the bus, the image capturing apparatus 101 is controlled to acquire a real-time image, mark face image information in the real-time image, such as passenger a, passenger b, passenger c, and the like, and acquire the current time as 13:45 as the first moment, record passenger a, passenger b, and passenger c, respectively, as passenger a, passenger b, and passenger c at t1=13: 45 into the elevator. Meanwhile, the remote server analyzes the real-time image acquired by the image capturing device 101 in real time, and determines whether the coordinates (x, y) of the human wrist joints of the passenger a, the passenger b and the passenger c fall in the calling device area a, for example: and displaying that the passenger a and the passenger b perform elevator calling operation in the real-time image, identifying that the passenger a and the passenger b finish elevator calling operation according to the coordinates of the human wrist joints of the passenger a and the passenger b and recording the elevator calling operation in a database of the remote server by the remote server, and judging that the elevator is not called by the passenger c.
Then, when the remote server detects that the car door 105 is changed from the door-closed state to the door-open state through the bus, the image capturing apparatus 101 is controlled to suspend capturing of the real-time image, thereby reducing power consumption. Next, when the remote server detects the transition of the car door 105 from the door open state to the door closed state again through the bus, the image capturing apparatus 101 acquires a real-time image, marks and records to the passenger a, the passenger c, and the passenger d, and acquires the current time such as t2=13: 47, records passenger a, passenger b, passenger c, and passenger d, respectively. The server determines that passenger b has arrived at specified floor b and left the elevator because passenger b is not detected a second time passenger a and passenger c have a boarding time t2-t1, i.e., passenger a and passenger c have a boarding time of 2 minutes, wherein passenger a has completed the elevator-calling operation and recorded in the database of the remote server, and thus will not alert passenger a. However, the passenger c is judged to be in an unbroken state and the boarding time is 2 minutes and more than the preset time is 1 minute, so that the passenger c is reminded on the acousto-optic device 102 inside the car 105. While passenger d is the first time entering the elevator, passenger d is recorded at t1=13: and 47 into the elevator. If the passenger d performs the elevator calling operation in the period, the information that the passenger d has completed the elevator calling operation is stored in a database of a remote server.
S204, if the passenger is judged not to carry out elevator calling operation within the preset time, reminding the passenger.
In step S204, the passenger who does not perform the elevator calling operation in the preset time is reminded, but the method is not limited to reminding only the passenger who does not perform the elevator calling operation in the preset time, and the passengers who do not take the elevator in a rule may be reminded, which is not limited specifically herein. When the remote server recognizes that the passenger does not call for a preset time, the elevator calling information of the passenger is acquired, the acousto-optic device 102 is controlled to display the elevator calling information, and the passenger is reminded. The elevator calling information comprises a passenger face image, passenger basic information and layer selection information. The acousto-optic device 102 includes a display screen for emitting an image alert to the passenger and a speaker for emitting an audible alert to the passenger. The passenger face image, passenger basic information and layer selection information can be input into a database of a remote server in advance. If the visitor of the building is, the information can be input in real time at the foreground of the building, so that the elevator calling information is ensured to be acquired. Illustratively, when the remote server recognizes that the passenger c does not call for a preset time, the remote server controls the display screen of the acousto-optic device 102 to display the name of the passenger c, the face image of the passenger c and the possible destination floor of the passenger c, and uses a speaker to prompt the passenger c in voice.
Optionally, the reminding method for calling elevator in the car according to the embodiment of the application may further include the following steps:
acquiring the opening and closing state of a car door;
if the car door enters a door closing state from a door opening state, executing the step of acquiring a real-time image in the car; if the car door enters the door-open state from the door-closed state, the step of acquiring a real-time image of the inside of the car is not performed.
In this embodiment, when the remote server detects that the car door 105 is changed from the door-closed state to the door-open state through the bus, the image capturing apparatus 101 may be selectively controlled to suspend capturing of the real-time image, thereby reducing power consumption.
Optionally, the reminding method for calling elevator in the car according to the embodiment of the application may further include the following steps:
and sending the elevator calling information corresponding to one or more passengers to a database in a server for storage.
In this embodiment, the elevator calling information corresponding to the passenger is sent to the database in the server for storage, and the destination floor selected by the passenger can also be stored, and when the remote server detects that the car door 105 is changed from the door open state to the door closed state through the bus, the data is updated. According to the elevator system, the elevator calling information and the target floors corresponding to the passengers are stored in the database, and the elevator calling information and the target floors of the passengers can be learned through the deep learning module, so that the elevator system can directly determine the target floors corresponding to the passengers by identifying the faces. Through this embodiment can make the passenger need not to carry out the operation of calling the ladder and can appointed the elevator and arrive the target floor, not only avoid the passenger to forget to call the ladder and waste time, still avoid taking the elevator limited space, reduced elevator operating time and energy consumption.
Based on the foregoing description, taking an elevator as an example, as shown in fig. 4, a reminding method for calling an elevator in a car in the embodiment of the application specifically includes the following steps:
s201, acquiring a real-time image in a car;
s202, identifying and detecting the real-time images to obtain elevator calling information of one or more passengers in the real-time images;
s203, judging whether one or more passengers perform elevator calling operation within a preset time according to elevator calling information;
s204, if the passenger is judged not to carry out elevator calling operation within the preset time, reminding the passenger.
For example, assuming that the preset time is 1 minute, that is, more than 1 minute, the passenger is determined that the elevator calling operation is not performed within the preset time, and the passenger is reminded. After the passenger a, the passenger b, and the passenger c enter the car, when the remote server detects that the car door 105 is changed from the door opening state to the door closing state through the bus, the image capturing device 101 is controlled to obtain a real-time image, mark face image information in the real-time image, such as the passenger a, the passenger b, the passenger c, and the like, and obtain the current time, such as 13:45 as the first moment, record passenger a, passenger b, and passenger c, respectively, as passenger a, passenger b, and passenger c at t1=13: 45 into the elevator. During this period, passenger a and passenger b perform a elevator calling operation. Meanwhile, the remote server analyzes the real-time image acquired by the image capturing device 101 in real time, and respectively judges whether the coordinates (x, y) of the human wrist joints of the passenger a, the passenger b and the passenger c fall in the calling device area a, and the remote server recognizes that the passenger a and the passenger b have completed the calling operation according to the coordinates of the human wrist joints of the passenger a and the passenger b and records the calling operation in the database of the remote server, and the passenger c judges that the calling state is not called.
Then when the remote server detects a transition of the car door 105 from the closed to the open state over the bus, passenger b leaves the elevator and passenger d enters the car and uses the recall device. Meanwhile, the server controls the image capturing apparatus 101 to suspend capturing of real-time images, thereby reducing power consumption. Next, when the remote server detects the transition of the car door 105 from the door open state to the door closed state again through the bus, the image capturing apparatus 101 acquires a real-time image, marks and records to the passenger a, the passenger c, and the passenger d, and acquires the current time such as t2=13: 47, records passenger a, passenger b, passenger c, and passenger d, respectively. Because passenger b is not detected a second time, the server determines that passenger b has reached designated floor b and left the elevator. The boarding time of the passenger a and the passenger c is t2-t1, namely the boarding time of the passenger a and the passenger c is 2 minutes, wherein the passenger a finishes the boarding operation and records the boarding operation into a database of a remote server, so that the passenger a is not reminded. However, the passenger c is judged to be in an unhooked state and the boarding time is 2 minutes and is longer than the preset time by 1 minute, so that the passenger c is reminded on the acousto-optic device 102 in the car 105, for example, the display screen of the acousto-optic device 102 is controlled to display the name of the passenger c, the face image of the passenger c and the possible target floor of the passenger c, and the loudspeaker is used for reminding the passenger c in a voice manner. While passenger d is the first time entering the elevator, passenger d is recorded at t1=13: and 47 into the elevator. Because the passenger d performs the elevator calling operation, the server stores information that the passenger d has completed the elevator calling operation into the database.
From the above, the present application obtains a real-time image in the car, then identifies and detects the real-time image, obtains elevator calling information of one or more passengers in the real-time image, then determines whether the one or more passengers perform elevator calling operation within a preset time according to the elevator calling information, and if it is determined that the passengers do not perform elevator calling operation, sends a reminder to the passengers. By the method, passengers who do not call the elevator within the preset time can be reminded to call the elevator, so that time waste caused by forgetting to call the elevator by the passengers is avoided, limited space of the elevator is also avoided, and the running time and energy consumption of the elevator are reduced.
Referring to fig. 3, a reminding system for calling elevator in a car according to an embodiment of the present invention includes:
the first module is used for acquiring real-time images in the car;
the second module is used for identifying and detecting the real-time images and acquiring elevator calling information of one or more passengers in the real-time images;
