Detailed Description

In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

In order to explain the technical means of the present invention, the following description will be given by way of specific examples.

In order to facilitate that users on each floor in the building can use the elevator to reach each floor, elevator cars on each floor are provided with elevator riding buttons comprising an ascending button and a descending button (generally, only the descending button is arranged on the top floor, and only the ascending button is arranged on the 1 st floor), when the users press the ascending button or the descending button, the elevator reaches the floor where the users are located, and therefore the users can use the elevator to reach the selected floor.

The existing elevator directly runs to the floor after receiving an instruction of pressing an elevator taking button by a user in the running process, and whether the user stays at the floor where the elevator taking button is pressed is not further confirmed, if the elevator runs to the floor, the user leaves the floor (for example, the user returns to a room, selects to walk a staircase or takes other elevators to leave), the stay of the elevator at the floor is invalid, and the running efficiency of the elevator is greatly reduced.

Referring to fig. 1, in order to avoid invalid stop during elevator operation and improve the operation efficiency of an elevator, an embodiment of the present invention provides an elevator operation control system 10, which includes a control module 11, a first obtaining module 12, and a second obtaining module 13, where the first obtaining module 12 and the second obtaining module 13 are both connected to the control module 11. For convenience of description, it is considered that at least one elevator is in a building, an elevator selected by a user to take an elevator in the building is a target elevator, and a floor where the user to take the elevator is located is a floor to take. Every floor of this building all is provided with the elevator room, and the elevator room of every floor all is provided with first acquisition module 12, all is provided with second acquisition module 13 in every elevator, and first acquisition module 12 that every floor set up and the second acquisition module 13 that sets up in every elevator all are connected with control module 11, and it can gather corresponding data under control module 11's control to and provide corresponding information for the user. Of course, the elevator operation control system 10 may also include other modules, such as a speaker disposed in the elevator car at each floor, through which voice information is played to the user.

The information acquired by the first acquiring module 12 may be set as needed. For example, referring to fig. 2, the first obtaining module 12 may include a first command obtaining unit 121, configured to obtain a first elevator taking command of a user outside the target elevator, and transmit the first elevator taking command to the control module 11. The first instruction acquisition unit 121 may include a sound collection unit, such as a microphone; a gesture recognition unit, such as an infrared sensing gesture recognition unit, may also be included. For another example, the first obtaining module 12 may further include a first image capturing unit 122, configured to obtain a first image of the user outside the target elevator, and transmit the first image to the control module 11, so that the control module 11 may determine the number of users according to the first image.

The information acquired by the second acquiring module 13 may be set as needed. For example, referring to fig. 2, the second obtaining module 13 may include a second instruction obtaining unit 131, configured to obtain a second elevator taking instruction of the user in the elevator, and transmit the second elevator taking instruction to the control module 11. For another example, the second obtaining module 13 may further include a second image capturing unit 132 for obtaining a second image of the users in the elevator and transmitting the second image to the control module 11, so that the control module 11 may determine the number of the users in the elevator according to the second image. For another example, the second obtaining module 13 may further include a pressure sensing unit 133 disposed in the elevator, where the pressure sensing unit 133 is configured to obtain total user pressure data borne by the elevator, and the control module 11 may determine the total weight in the elevator according to the pressure data, so as to further determine the remaining number of people that can be accommodated in the elevator.

In order to better control the operation process of the elevator and improve the operation efficiency, the embodiment of the invention also provides an elevator operation control method, which can be realized by the elevator operation control system and also can be realized by other devices or systems, and the method is not limited here. The embodiment of the invention takes the elevator operation control system as an example to explain the implementation process of the elevator operation control method.

Referring to fig. 3, an elevator operation control method provided in an embodiment of the present invention includes the following steps:

step S21: and determining elevator taking information of the user according to the acquired first elevator taking instruction, wherein the elevator taking information at least comprises the floor to be taken where the user is and a target elevator selected by the user.

In this embodiment, the target elevator is one of the elevators in the building, and is determined according to the actual selection of the user, that is, the elevator for which the user inputs the first elevator riding command is the target elevator. The control module 11 acquires a first elevator taking instruction of a user through the first acquisition module 12; after the first elevator taking instruction is obtained, elevator taking information of the user can be determined according to the first elevator taking instruction, the elevator taking information can comprise a floor to be taken where the user is located, when more than one elevator in the building, a target elevator selected by the user can be further included, and information such as the elevator taking direction of the user can be further included.

Step S22: and determining the target floor and the remaining number of passengers of the user in the target elevator according to the acquired second elevator taking instruction of the user in the target elevator and the user information.

In the embodiment, when the number of elevators in the building is one, the elevator is a target elevator selected by a user to take the elevator; when the number of the elevators is two or more, the target elevator is one of all the elevators selected by the user. The second elevator taking command comprises the floor information pressed by the user in the elevator through the buttons in the elevator, and therefore the target floor required by the user in the elevator can be determined. The user information may include the number of users in the running elevator, which may be determined by the second image collected by the second image collecting unit 132 of the second obtaining module 13 in conjunction with the control module 11; the user information may also include the total weight of the user in the running elevator, which may be determined by the total pressure data collected by the pressure sensing unit 133 of the second acquisition module 13 in conjunction with the control module 11.

Step S23: and determining the floor to which the target elevator is to arrive according to the current floor where the target elevator is located, the target floor, the number of remaining passengers and the floor to be taken.

In this embodiment, when a user in the target elevator selects a target floor, or a user outside the target elevator selects a floor to be taken, the target elevator starts to operate, and the control module 11 may preliminarily determine a floor to be stopped in the process of the target elevator operating in the operating direction, that is, a floor to which the target elevator will arrive, according to the current floor where the target elevator is located, the target floor selected by the user in the elevator, the number of remaining persons that can be taken, and the floor to be taken selected by the user outside the elevator. It is understood that the destination elevator, i.e. the floor to be reached, may be one of the destination floors or one of the floors to be taken.

Step S24: and when the destination elevator is the floor to be taken, acquiring the number of users of the floor to be taken.

As seen from step S23, the floor to which the target elevator is going to arrive may be one of the target floors or one of the floors to be occupied. When the floor to which the target elevator is going to arrive is a floor to be taken, the floor to which the elevator needs to stay next is the floor to be taken, the number of users of the floor to be taken needs to be determined, and whether the elevator needs to stay on the floor is determined according to the number of the users. For example, when the number of users at the floor to be taken is zero, it means that although there is a need for taking a car at the floor, when the destination elevator is going to reach the floor, the user is not at the floor, and it is necessary to determine whether there is a need to stop at the floor according to the actual number of users at the floor to be taken.

Step S25: and when the number of the users of the floor to be taken is less than a preset value, determining the stop floor of the target elevator according to the current floor where the target elevator is located and the target floor.

After the number of users on the floor to be occupied is obtained, whether the number of users is smaller than a preset value needs to be judged. The preset value here may be 1, or may be another value. It can be understood that when the preset value is 1 and the number of users is less than 1, it means that no user needs to take the elevator at the floor, and at this time, the floor to which the elevator will arrive needs to be determined again. When the floor to which the elevator is to arrive is re-determined, the determination is only needed according to the current floor where the target elevator is located and the target floor, and the determined floor to which the elevator is to arrive is a stopping floor.

Step S26: and when the number of the users of the floor to be taken is not less than a preset value, determining the floor to be taken as the stop floor of the target elevator. When the number of users is not less than 1, it means that there is a need for a user to take the elevator at the floor, and thus the floor to be taken is a stop floor at which the target elevator is to be stopped.

Step S27: controlling the target elevator to travel to the stopping floor.

After determining the stop floor, the control module 11 may control the destination to travel to the stop floor. It is understood that after the above step S26 is completed, the process returns to step S21, that is, the above process is repeated, so that the elevator can be dispatched and the operation control of the elevator can be realized.

The elevator operation control method provided by the embodiment of the invention has the beneficial effects that at least: the embodiment of the invention acquires the number of users of the floor to be occupied in the running process of the elevator, controls the running of the elevator by combining the number of users of the floor to be occupied, and when the number of users of the floor to be occupied is zero, the number means that no person is actually present in the floor to be occupied when the elevator is about to run to the floor to be occupied, and at the moment, the floor to be reached by the elevator is re-determined, so that the elevator does not stop at the floor to be occupied, the invalid stop of the elevator at the floor is avoided, and the running efficiency of the elevator is effectively improved.

Referring to fig. 4, in one embodiment, step S21 may include the following steps:

step S211: the method comprises the steps of obtaining a first elevator taking instruction, wherein the first elevator taking instruction comprises the elevator taking direction and position information of a user.

For the users on the 1 st floor, the direction of riding the stairs is usually upward; for the users in the middle floor, the elevator taking direction can be upward or downward, and the selection is carried out according to the actual situation; for the users on the top floor, the direction of riding the elevator is usually downward. In this embodiment, the first obtaining module 12 arranged on the floor to be taken along obtains the direction of taking the elevator by the user, and also obtains the position information of the user, and forms a first elevator taking instruction and then sends the first elevator taking instruction to the control module 11.

The manner in which the first obtaining module 12 obtains the first elevator taking instruction may be selected as needed. For example, the first obtaining module 12 may obtain the elevator taking command by an elevator taking button corresponding to the target elevator and arranged on the floor to be taken, and when the user presses the elevator taking button, the first obtaining module 12 obtains the elevator taking command. For another example, the voice information may be sent to the voice collecting unit when the user needs to take the elevator, the voice may include information including the elevator taking or taking direction, such as "i want to take the elevator", "i want to take the elevator to go upstairs", "i want to take the elevator to go downstairs", and the like, the voice collecting unit obtains the voice information and then sends the voice information to the control module 11, and the control module 11 obtains the elevator taking direction and the position information of the user according to the collected voice information. In some embodiments, in consideration of security issues of the community, the identity authentication of the user may also be implemented by the control module 11 performing voiceprint recognition on the voice, and the voice information is extracted only after the identity authentication is passed. For another example, the gesture recognition unit corresponding to the target elevator is set on the floor to be taken, when the user needs to take the elevator, the user can make a corresponding gesture in front of the gesture recognition unit, and the gesture recognition unit recognizes the gesture after acquiring the gesture to obtain a first elevator taking instruction of the user and send the first elevator taking instruction to the control module 11. Of course, in other embodiments, the first boarding command may be obtained in other manners, and is not limited to the above-mentioned case.

Step S212: and determining the target elevator selected by the user and the floor to be taken according to the position information contained in the first elevator taking command.

Here, the location information includes a floor on which the user is located; when each floor has multiple elevators, the location information also includes which elevator of the floor the user selected. It is understood that the number of floors to be occupied may include more than one, and when the users on different floors respectively issue the first elevator riding command, the control module 11 correspondingly marks the floors to be occupied where the different users are located after receiving the first elevator riding command.

Referring to fig. 5, in one embodiment, step S22 may include the following steps:

step S221: and determining a target floor of the user in the target elevator according to the acquired second elevator taking instruction of the user in the target elevator, wherein the second elevator taking instruction is acquired through an elevator taking button arranged in the target elevator. Of course, in other embodiments, the second elevator taking instruction may be obtained in other manners, which is not limited herein.

The second elevator taking command includes information on the floor where the user presses the button in the elevator, and the control module 11 can determine the destination floor where the user needs to go in the destination elevator.

Step S222: and determining the number of the remaining passengers in the target elevator according to the acquired user information in the target elevator, wherein the user information comprises the number of the users in the target elevator and/or the total weight of the users in the target elevator.

Referring to fig. 6, when the user information includes the number of users in the target elevator, step S222 may include the steps of:

step S311: and controlling a second image acquisition unit in the target elevator to acquire a second image in the target elevator.

A second image capturing unit 132 is provided in the target elevator for capturing a second image of the user in the elevator. The second image capturing unit 132 may be a general camera, or a general camera + TOF depth camera. The frequency of the second image capturing unit 132 for capturing images may be set as required, for example, the images may be captured when the second elevator instruction is obtained, or the images may be captured when the elevator is started every time, and the like, which is not limited herein.

Step S312: and performing image recognition on the second image, and confirming the number of users in the second image so as to acquire the number of users in the target elevator.

After obtaining the second image, the control module 11 may identify people in the second image based on a head detection method of Hough transform, so as to determine the number of users. The Hough transform is a parameter estimation technology using a voting principle, and the principle is that the detection problem in an image space is converted into a parameter space by using the point-line pair duality of the image space and the Hough parameter space, so that the Hough transform can be applied to the field of image processing and is used for people counting. Firstly, according to an input image (here, a second image), obtaining a difference image through interframe difference method processing, and carrying out binarization processing on the difference image to obtain a region with a person in the image; secondly, carrying out edge detection and extraction on the region with people through a Sobel operator or a Canny operator to obtain the contour of the target; then, randomly sampling three or more points which are not on the same straight line, determining to perform random Hough transformation to implement circle detection, and extracting a human head region; finally, the number of people is obtained by counting the heads. Of course, in other embodiments, the image recognition may be performed in other manners to obtain the number of users in the second image.

Step S313: and determining the remaining number of passengers capable of taking in the target elevator according to the rated carrying capacity of the target elevator and the obtained number of the users in the target elevator. Specifically, the number of persons in the target elevator is subtracted from the rated number of persons in each running elevator, and the remaining number of persons in the target elevator is obtained.

Referring to fig. 7, when the user information includes the total weight of the users in the target elevator, step S222 may include the steps of:

step S314: and controlling a pressure sensing unit in the target elevator to acquire the total weight of the user in the target elevator. The pressure sensing unit 133 is configured to obtain user total pressure data received in the elevator, and the control module 11 may determine the total weight in the elevator according to the pressure data.

Step S315: and determining the residual load capacity of the target elevator according to the rated load capacity of the target elevator and the total weight of users in the target elevator. Specifically, the residual load capacity in the target elevator is obtained by subtracting the total weight in the target elevator from the rated load capacity of the target elevator.

Step S316: and determining the number of remaining passengers capable of taking in the target elevator according to the remaining load capacity of the target elevator and the preset per capita weight. Specifically, the remaining carrying capacity of the target elevator is divided by the preset per-capita weight, and the result is rounded, so that the remaining number of passengers in the target elevator can be obtained.

When the method is adopted to determine the remaining number of people capable of taking, the number of people in the elevator is not directly estimated according to the total weight in the elevator, but the remaining number of people capable of taking is estimated according to the remaining load capacity in the elevator, so that the influence of interference factors such as other heavy objects in the elevator is avoided, and the estimation result is more accurate.

Referring to fig. 8, in one embodiment, step S23 may include the following steps:

step S231: and determining the floor to be ridden which is closest to the current floor in the floors to be ridden and is not reached as a candidate floor to be ridden according to the running direction of the target elevator and the current floor. For example, the traveling direction of the target elevator is upward traveling, the current floor is floor 1, the floors to be ridden include floors 3 and 5, and if the floor to be ridden closest to the current floor among the floors to be ridden which are not reached is floor 3, floor 3 is determined as a candidate floor to be ridden.

Step S232: and determining a target floor closest to the current floor in the target floors which are not reached as a candidate target floor according to the running direction of the target elevator and the current floor. For example, if the traveling direction of the destination elevator is upward traveling, the current floor is floor 1, the destination floors include floors 4 and 7, and the destination floor closest to the current floor among the floors to be ridden that have not arrived is floor 4, then floor 4 is determined as the candidate destination floor.

Step S233: and judging whether the number of the remaining persons is not less than a preset value. The preset value here may be 1. Of course, in other embodiments, the preset value may be other values.

If the remaining number of passengers is not less than the preset value, it means that the target elevator can continue to take a new elevator user, and at this time, step S234 may be performed;

step S234: and judging whether the distance between the candidate floor to be ridden and the current floor is greater than the distance between the candidate target floor and the current floor.

If the distance between the candidate floor to be ridden and the current floor is not greater than (i.e. less than or equal to) the distance between the candidate target floor and the current floor, then:

step S235: and determining the floor to which the target elevator is about to arrive as the candidate floor to be taken.

Taking the foregoing example as an example, if the current floor is floor 1, the candidate floor to be ridden is floor 3, and the candidate target floor is floor 4, then the distance between the candidate floor to be ridden and the current floor is less than the distance between the candidate target floor and the current floor, and therefore the floor to which the target elevator is going to arrive is determined to be the candidate floor to be ridden.

If the remaining number of passengers is less than the preset value, it means that the remaining number of passengers of the target elevator is 0, and a new user for taking the elevator cannot be accommodated, and then step S236 may be performed.

If the distance between the candidate floor to be ridden and the current floor is greater than the distance between the candidate target floor and the current floor, step S236 may be performed.

Step S236: determining the candidate target floor as a stopping floor of the target elevator. In one embodiment, when the floor to which the target elevator is going to arrive is a candidate target floor, the number of users who take the elevator floor does not need to be judged.

In one embodiment, when the floor to which the target elevator will arrive is the candidate floor, it means that the target elevator will stop at the candidate floor, and the number of users at the candidate floor needs to be acquired. Referring to fig. 9, step S24 may include the following steps:

step S241: and controlling a first image acquisition unit of the floor to be taken to acquire a first image of the floor to be taken.

The first image collecting unit 122 may be a general camera, or a general camera + TOF depth camera, and is configured to collect an image. The frequency of the first image capturing unit 122 for capturing images can be set according to needs, for example, images can be captured at preset intervals.

Step S242: and performing image recognition on the first image to acquire the number of users in the first image.

After obtaining the first image, the control module 11 may identify people in the first image based on a head detection method of Hough transform, so as to determine the number of users. Of course, in other embodiments, the image recognition may be performed in other manners to obtain the number of users in the first image.

Step S243: and confirming the number of the users on the floor to be taken according to the number of the users in the first image.

After the number of users in the first image is obtained, the number of users on the floor to be taken needs to be further determined according to different situations. Referring to fig. 10, in the present embodiment, the step S243 may include the following steps:

step S321: and judging whether the number of the users in the first image is smaller than a preset value, wherein the preset value is preferably 1, namely judging whether the number of the users in the first image is 0.

If the number of users in the first image is not less than a first preset value, which means that users wait for taking the elevator, then:

step S322: and confirming that the number of users in the first image is the number of users on the floor to be taken.

If the number of users in the first image is smaller than a preset value, that is, the number of users identified in the first image is 0, different methods can be adopted for processing.

Referring to fig. 10, in the first mode, if it is necessary to further confirm whether no one takes the elevator, step S323 is performed:

step S323: and playing voice inquiry instructions of preset times to the floor to be taken in a voice broadcasting mode. If no one answers, it means that the floor to be taken is not waiting for the elevator by the user at the moment, so that the floor to be taken can be cancelled, and the target elevator does not need to stay at the floor to be taken, then:

step S324: and confirming that the number of users in the first image is the number of users of the floor to be taken, and canceling the floor to be taken.

If someone answers the voice inquiry command, it means that there is a user waiting for the elevator on the floor to be taken, then step S325 is performed:

step S325: and recognizing the response voice and confirming the number of the recognized users as the number of the users on the floor to be occupied.
