Detailed Description

In the following description, for purposes of explanation and not limitation, specific details are set forth such as the particular system architecture, techniques, etc., in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application 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 application with unnecessary detail.

It should be understood that the terms "comprises" and/or "comprising," when used in this specification and the appended claims, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

Furthermore, the terms "first," "second," "third," and the like in the description of the present specification and in the appended claims, are used for distinguishing between descriptions and not necessarily for indicating or implying a relative importance.

The elevator management method applied to the building can be applied to electronic equipment capable of controlling an elevator, such as a desktop computer, a server, a notebook computer, an ultra-mobile personal computer (UMPC) and a smart phone. In particular, the electronic device is in particular a control device of an elevator, such as a central control terminal of an elevator.

Fig. 1 schematically illustrates an elevator management system according to an embodiment of the present application. Referring to fig. 1, the elevator management system includes: an elevator 11 and an electronic device 12, wherein the electronic device 12 can control the elevator 11 to move within various floors in a building. The elevator 11 comprises an elevator cabinet 111, a counterweight 112 and a counterweight rail 113. A first inductance coil 114 is disposed on the counterweight 112, a second inductance coil 115 is disposed on the counterweight rail 113, and the first inductance coil 114 is electrically connected to a storage battery 116 in the elevator.

In the present embodiment, when the second induction coil 115 is energized, the first induction coil 114 generates an induction current due to the electromagnetic induction effect, and then charges the power storage battery 116 electrically connected to the second induction coil 115. At the same time, since the second inductance coil 115 generates an inductance current, a magnetic field opposite to the first inductance coil 114 is generated, so that a corresponding electromagnetic induction force is generated, and the direction of the electromagnetic induction force is different from the moving direction in the descending process of the elevator, so that the acceleration in the descending process of the elevator is reduced, and the descending speed of the elevator is reduced. In order to avoid the situation that the user needs to wait for a long time due to too slow speed, the electronic device 12 can control the energizing current of the first induction coil 114, so that the induction current on the second induction coil 115 can be controlled, the purpose of precisely controlling the electromagnetic induction force is achieved, and the accuracy of elevator speed control is improved.

Referring to fig. 2, fig. 2 shows an implementation schematic diagram of an elevator management method applied to a building, where the management method is applied to an electronic device provided by the embodiment of the present application, and the electronic device may be an electronic device 12 in fig. 1, where the electronic device 12 may be disposed on an elevator 11, or may be an independent control terminal, that is, may control multiple elevators 11 in the building at the same time, and may specifically be set according to practical situations. Specifically, the method comprises the following steps:

in S201, a user action of any user in the building is acquired.

In this embodiment, at least one distributed terminal may be disposed in each floor of the building, where the distributed terminal may be a camera module, or may be another module that may be used to collect user action information, such as an infrared thermal sensing module, where an electronic device may establish communication connection with each distributed terminal in a wired manner or a wireless manner, and then receive collected data fed back by each distributed terminal, and obtain, by analyzing the collected data, user actions of any user that is active in the building.

In one possible implementation manner, the collected data fed back by the distributed terminal is video data. In this case, the electronic device may be configured with a face recognition algorithm, import the video data into the face recognition algorithm, determine whether the video data includes a face, and mark at least one video image frame including a face region in the video data. Based on a plurality of continuous video image frames containing the same face, user actions of the user corresponding to the face are determined.

In this embodiment, the user actions include: characteristic information of at least one dimension such as motion amplitude, motion type and motion orientation of a user. Wherein the motion amplitude can be used to determine the speed at which any of the users moves in the corridor, so that the length of time the user needs to move to the elevator hoistway can be determined by the speed of movement; the action type can be used for determining the moving mode of the user, such as slow walking, quick action, standing and stopping, and the like, so that whether the follow-up departure condition is met can be judged; the above-described motion direction can determine the moving direction of the user, i.e., determine whether the user moves in the direction of the elevator car for determining whether the following departure condition is satisfied.

In S202, if the user action satisfies the departure condition corresponding to the any user, determining an elevator moving direction of the elevator according to the current first floor of the elevator and the second floor where the user is located.

In this embodiment, after obtaining a user action of any user in a building, the electronic device may obtain a departure condition corresponding to the any user, and match the user action with the departure condition. If the user action matches the departure condition, indicating that the user needs to take an elevator, and executing the operation of S202; otherwise, if the user action does not match the departure condition, the user does not need to take the elevator, and at this time, the elevator can be controlled to operate according to the original action rule.

In one possible implementation, the departure conditions corresponding to different users may be the same, in which case the electronic device may match the user action with a general departure condition to determine whether the user needs to take an elevator.

In one possible implementation, the departure conditions corresponding to different users may be different. Since different users have different behavior habits, the same actions have different meanings for different users. Based on this, the electronic device may store behavior records corresponding to each user, and generate departure conditions corresponding to the user based on a plurality of historical behavior records. After the electronic device obtains the user action of any user, the electronic device can obtain the corresponding departure condition according to the user identification (such as face information or house number in building) corresponding to the user, and match the user action with the departure condition.

In this embodiment, when the electronic device detects that the user operation satisfies the corresponding departure condition, it indicates that the user needs to take an elevator, and at this time, the user does not reach the elevator hall and does not light the control button corresponding to the elevator hall. In this case, the electronic device will acquire the floor of the building where each elevator is currently located, i.e. the first floor described above, and determine the corresponding elevator movement direction based on the second floor where the user predicted to be in need of an elevator is located.

If the second floor where the user is located is lower than the first floor where the elevator is located, namely the moving direction of the elevator is a downlink moving direction; conversely, if the second floor where the user is located is higher than the first floor where the elevator is located, the moving direction of the elevator is the upward moving direction.

In one possible implementation, if the direction of movement is in the upward direction, power is supplied to the motor on the counterweight guide rail by means of a battery to control the position of the counterweight on the counterweight guide rail, moving the elevator to the second floor. Because in the process of upward movement of the elevator, gravitational potential energy cannot be converted into electric energy, at the moment, relevant judgment operation of power generation control is not needed, and the counterweight can be directly controlled to move on the counterweight guide rail through the energy storage battery so as to lift the elevator to a second floor where a user is located.

In one possible implementation, the electronic device can determine the current use status of the respective elevator. If the elevator is in a use state, such as that there is a user in the elevator and the elevator corresponds to a target floor, or other users on other floors click a corresponding control button (such as an up button or a down button) to instruct the elevator to move towards other floors on which other users are located, at this time, the electronic device will determine the target moving direction of the elevator in the use state, if the target moving direction is inconsistent with the determined moving direction, that is, the elevator will not pass through the second floor on which the user is located in the process of completing the existing instruction, and at this time, the operation of S202 will be executed after the elevator completes the existing instruction.

The floor on which the user is located is illustratively floor 10, at which time the elevator is at floor 9 and the other users are transported to floor 1, in which case the elevator does not pass the floor on which the user is located during the transportation of the other users, at which point the electronic device will perform the relevant operation at S202 after the elevator transports the other users to floor 1.

In some implementations, if the target moving direction is consistent with the determined moving direction, that is, the elevator passes through the second floor where the user is located in the process of completing the existing instruction, at this time, the relevant operations of S202 to S204 may be performed to determine whether to convert gravitational potential energy into electric energy, and store the electric energy in the energy storage battery.

The floor on which the user is located is illustratively 10 floors, at which time the elevator is at 20 floors, and the other users are transported to 1 floor, in which case the elevator passes the floor on which the user is located during the transportation of the other users, at which time the electronic device may perform the operations associated with S202-S204.

In one possible implementation manner, if a building includes a plurality of elevators, the electronic device will first control the elevators in the in-use state and having the target moving direction the same as the moving direction to move to a second floor where any user is located; if all the target moving directions of the elevators in the using state do not pass through the second floor where the user is located, judging whether an idle elevator exists or not, and executing the related operations of S202-S204 on the elevators in the idle state.

In S203, if the elevator moving direction is the downward direction, the energizing current of the second induction coil is determined based on the current first weight of the elevator and the floor difference between the second floor and the first floor.

In this embodiment, the electronic device may calculate a floor difference between the second floor and the first floor, and according to the floor height between each floor, may calculate a movement distance corresponding to the elevator, and according to the movement distance, may determine a desired movement speed corresponding to the elevator. Because the main source of acceleration is gravity acceleration in the descending process of the elevator, and an electromagnetic induction force opposite to the gravity direction is generated in the process of generating electric energy, the actual acceleration of the elevator in the descending process is determined according to the difference between the gravity and the electromagnetic induction force. The magnitude of the electromagnetic induction force is related to the energizing current of the second induction coil, based on the magnitude of the electromagnetic induction force, the electronic equipment can determine the expected moving speed of the elevator according to the floor difference, then determine the expected acceleration, calculate the corresponding electromagnetic induction force according to the first weight and the expected acceleration, and obtain the energizing current according to the electromagnetic induction force, the first inductance of the first induction coil and the second inductance of the second induction coil.

The electromagnetic induction force may be expressed as:

Wherein, Is the desired acceleration described above; m is the first weight described above; the electromagnetic induction force is as described above; g is a gravitational constant.

In S204, the second electricity-sensitive coil is energized based on the energizing current, and the elevator is controlled to move in the downward direction to charge the electricity-storage battery.

In this embodiment, after the current flowing through the second inductance coil is determined, the electronic device determines the current flowing through the second inductance coil, and then controls the acceleration of the elevator moving from the first floor to the second floor through controlling the current flowing through the second inductance coil, so that the elevator can be lowered to the second floor where any user is located within the preset moving duration, and accurate control of elevator movement is achieved.

It should be noted that, since the elevator includes an acceleration stage, a uniform movement stage and a deceleration stage in the movement process, the electronic device may determine the corresponding current according to the acceleration requirements corresponding to each stage, that is, the determined current is not a fixed value, but is related to the stage in the movement process, and the electronic device may determine the corresponding current according to the stage in the movement process of the elevator.

In this embodiment, the electronic device may not only control the movement speed of the elevator by controlling the current, but also move the elevator to the second elevator within a preset movement time period, and since the first inductive coil may generate a corresponding inductive current, the loop where the first inductive coil is located may charge the storage battery, so as to achieve the purpose of converting gravitational potential energy into electric energy. The power storage battery can be used for controlling the operation of an engine on the counterweight guide rail, so that the floor corresponding to the elevator is adjusted by controlling the position of the counterweight on the counterweight guide rail. In some implementations, a display module may also be included in the elevator, and the above-described storage battery may also be used to power the display module and also may be used to power a lighting module in the elevator.

As can be seen from the foregoing, in the elevator management method applied to a building provided by the embodiment of the present application, a relevant distributed terminal may be configured in the building, user actions of a user in the building are collected, and whether the user has a need to take an elevator is determined according to the user actions, that is, whether the user actions meet the above-mentioned departure conditions is determined, when the departure conditions are detected to be met, a moving direction of the elevator can be determined, and in the case that the moving direction of the elevator is in a downlink direction, that is, gravitational potential energy of a cabinet of the elevator can be converted into electric energy for storage, and in order to improve accuracy of elevator control, the electronic device may determine corresponding current according to current weight of the elevator and user actions, so as to generate corresponding induced current due to an inductive effect through a first inductive coil disposed on a counterweight and a second inductive coil disposed on a counterweight guide rail, and store the electric energy into an electric storage battery for use of the elevator, thereby achieving the purpose of saving energy. Different from the existing elevator management technology, in the process of converting gravitational potential energy of an elevator into electric energy, the embodiment of the application can dynamically adjust corresponding electrifying current according to floor difference between the elevator and a user, can control the elevator to move in advance, reduce waiting time of the user, can determine electrifying current in the power generation process, control resistance generated by power generation in the descending process, accurately control speed of the elevator in the descending process, and simultaneously ensure that the elevator reaches the floor where the user is located when the user arrives at the elevator room of the floor while saving energy, and improve use experience of the user.

Fig. 3 is a flowchart showing a specific implementation of an elevator management method applied to a building in S203 according to a second embodiment of the present application. Referring to fig. 3, with respect to the embodiment described in fig. 2, S203 in an elevator management method applied to a building provided in this embodiment includes: S2031-S2035 is specifically described as follows:

Further, if the moving direction of the elevator is a downward direction, determining the energizing current of the second inductance coil according to the current first weight of the elevator and the floor difference between the second floor and the first floor, including:

in S2031, a downlink movement distance is determined from the first floor and the second floor.

In this embodiment, the electronic device may calculate a floor difference between the first floor and the second floor, and calculate a downlink movement distance corresponding to the elevator descending from the first floor to the second floor based on the floor difference and a floor height corresponding to each floor.

Illustratively, the floor difference is FloorDis, each floor height is FloorHeight, and the following moves by: ldown = FloorDis × FloorHeight. If the inter-floor distances are not uniform, the above-mentioned downlink travel distance can be expressed as: ldown = FloorHeight (1) + FloorHeight (2) + … + FloorHeight (FloorDis), i.e. the corresponding floor heights of FloorDis floors are superimposed.

In S2023, the estimated movement time of the user is calculated from the user movement distance between the room position of the user and the elevator car of the floor where the user is located and the user action.

In this embodiment, the user action includes an action type and an action amplitude. The electronic device may determine a movement speed range of the user according to the action type in the user action, and then determine an expected movement speed matching the action amplitude in the movement speed range according to the action amplitude. For example, if the user action is of the jog type, the corresponding movement speed range is: a range of 0.5m/s to 1 m/s; the user action is of jogging type, and the corresponding moving speed range is 1 m/s-4 m/s. The electronic device may also determine the estimated movement speed corresponding to the movement speed range from the movement speed range according to the movement amplitude of the user, for example, if the movement speed range is a slow-walking type and the movement amplitude is a large amplitude, the corresponding estimated movement speed is 1m/s.

In this embodiment, the electronic device may obtain the location of the user, that is, the above-mentioned room location, through the distributed terminal, for example, determine the house number of the user, and since the electronic device may store the structure of each floor in the building, after determining the room location, the distance value between the room location and the elevator cab where the floor is located, that is, the estimated moving distance, may be calculated.

In this embodiment, the electronic device determines the estimated movement distance from the room position, and determines the estimated movement speed of the user from the user action, so as to calculate the ratio between the estimated movement distance and the estimated movement speed, thereby being able to calculate the estimated movement time required for the user to move to the elevator cab.

In S2033, a desired movement speed of the elevator is calculated from the downstream movement distance and the estimated movement time period.

In this embodiment the electronic device can control the speed of movement of the elevator so that the elevator can move to the second floor where the user is located when the user arrives in the elevator hoistway. Based on this, the above-mentioned estimated movement time period is the time period required for the user to move to the elevator car, and thus, the elevator movement time period can be determined based on the estimated movement time period. For example, the electronic device may take the estimated movement time period as the elevator movement time period, and in some implementations, may calculate a product between the estimated movement time period and a weighting coefficient, where the weighting coefficient may be any value less than 1 and greater than 0.

In some implementations, when determining the elevator movement duration of the elevator, the weighting coefficient may be a positive number greater than 1, in which case, the movement duration of the elevator may be slightly greater than the time required for the user to move to the elevator cabin, and the value of the weighting coefficient may be statistically determined according to historical experience, so that the power generation efficiency of the elevator can be considered, and the waiting duration required by the user can be reduced at the same time.

In this embodiment, since the elevator is not in a uniform motion process during operation, the elevator includes an acceleration stage, a uniform motion stage, and a deceleration stage, the electronic device may determine a stage duration corresponding to each stage according to the downlink movement distance, so as to determine, according to each stage duration, an expected movement speed corresponding to the uniform motion stage.

For example, the ratio of the time durations of the acceleration stage, the constant velocity stage and the deceleration stage is 1:3:1, and the expected movement time is 50s, where the time duration of the acceleration stage is 10s, the time duration of the constant velocity stage is 30s, and the time duration of the deceleration stage is 10s, and since the downlink movement distance is fixed, the expected movement speed corresponding to the constant velocity stage can be determined according to the time durations corresponding to the stages.

In S2034, a maximum drag coefficient is determined from the first weight and the desired movement speed.

In this embodiment, the electronic device may calculate, according to the acceleration duration corresponding to the acceleration stage and the desired movement speed, the desired acceleration corresponding to the acceleration stage. And determining an offset acceleration according to the difference between the expected acceleration and the gravity acceleration, determining an expected resistance value according to the first weight and the offset acceleration, and calculating the electromagnetic induction force according to the expected resistance value.

Illustratively, FIG. 4 shows a schematic diagram of the maximum drag coefficient provided by an embodiment of the present application. Referring to fig. 4, in the descending process of the elevator, the counterweight generates an upward gravity force due to the traction of the elevator, the gravity force is G, and at this time, due to the electromagnetic induction effect of the first inductance coil, a downward electromagnetic induction force, fb, is generated, and the electromagnetic induction force is the maximum resistance coefficient. The actual acceleration of the counterweight is (G-Fb)/Weight, which is the first Weight, under the influence of the maximum drag coefficient.

In some implementations, the maximum coefficient of resistance may be an electromagnetically induced force generated by the first electrically-conductive coil.

In some implementations, the maximum resistance coefficient may be a sum of an electromagnetic induction force generated by the first inductance coil and a friction force of the counterweight during movement of the counterweight guide rail. Specifically, the calculation of the friction force may be determined according to the historical movement condition of the counterweight, for example, a difference between the historical actual speed of the counterweight and the corresponding historical expected speed is measured, so that the friction force is determined according to the difference.
