Description

Technical Field

[0001] This invention relates to the field of elevator technology, specifically providing a motor control method. Background Technology

[0002] Most elevator systems now use physical buttons for floor selection. The number of buttons increases with the number of floors, so in buildings with many floors, the height difference between the buttons can be significant. Furthermore, since the button height is fixed and designed for the average adult height, elevator users are diverse, including the elderly, children, adults, and wheelchair users. When a child is allowed to press a button on a higher floor, they may not be able to reach it or may accidentally press another button.

[0003] Although some elevators in the current technology use virtual buttons on touch screens instead of physical buttons, the display area of ​​these buttons cannot be adjusted. Therefore, situations may still occur where the buttons cannot be reached or are accidentally pressed. Summary of the Invention

Therefore, it should not be construed as a limitation of this invention.

[0050] like Figure 1 The first embodiment of the present invention shown discloses an elevator control method. The elevator includes a car 10, a touch screen 20, and sensors. The touch screen 20 and sensors are both installed inside the car 10. The touch screen 20 has a rectangular structure and is vertically installed on the inner wall of the car 10, near the side of the elevator door. The top of the touch screen 20 is located at the position of an adult's head when standing, and the bottom of the touch screen 20 is located near the elevator floor. There are multiple display areas between the top and bottom of the touch screen 20 for displaying virtual buttons, so that passengers of different heights, such as adults, children, or wheelchair users, can operate the touch screen 20.

[0051] In this embodiment, the sensor is a millimeter-wave radar. Two millimeter-wave radars are respectively installed at two opposite corners of the top of the car 10 to ensure that there are no blind spots in the car 10. The millimeter-wave radar can detect the body parameters and position information of the passengers in the car 10.

[0052] The elevator control method includes the following steps:

[0053] Step S110: Obtain the location information between the passenger and the touchscreen 20;

[0054] Step S120: Based on the location information, select the passenger closest to the touchscreen 20 as the operating passenger;

[0055] Step S130: Obtain the body parameters of the passenger being operated on;

[0056] Step S140: Based on the physical parameters of the operating passenger, control the touch screen 20 to display virtual buttons in the display area located within the touch range of the operating passenger.

[0057] When in use, if the user is a tall adult, the virtual buttons will be displayed at a higher position on the touchscreen 20 for easier use. If the user is a short child or an elderly person in a wheelchair, the virtual buttons will be displayed in a lower area of ​​the touchscreen 20 for easier operation, thus improving user convenience.

[0058] It should be noted that the elevator control method of the present invention uses millimeter-wave radar to acquire the position information between passengers and the touch screen 20, which can determine the distance t between each passenger and the touch screen 20. Then, by comparing the distances between each passenger and the touch screen 20, the passenger closest to the touch screen 20 is selected as the passenger who needs to operate the elevator, i.e., the operating passenger. The height parameters of the operating passenger are then acquired using millimeter-wave radar, and based on these parameters, the touch screen 20 is controlled to display virtual buttons in a display area matching the operating passenger's height, thereby improving user convenience. This design is because, typically, when a passenger wants to operate the elevator, they walk to the elevator button location, observe the button, and then operate it. During this process, there are generally no other passengers between the passenger and the elevator operation button. In other words, the passenger closest to the elevator operation button is the operating passenger. Using this method, when there are multiple passengers in the car 10, the operating passenger and non-operating passenger can be accurately distinguished, improving the accuracy of the judgment.

[0059] It should also be noted that in this embodiment, millimeter-wave radar is used to acquire the positional information between the operator and the touchscreen 20. However, this is not limiting. In some other embodiments not shown in the figures, other sensors can be used instead of millimeter-wave radar, as long as they can acquire the positional information between the operator and the touchscreen 20, such as lidar. Compared with other sensors, using millimeter-wave radar has the following advantages:

[0060] (1) Small antenna aperture and narrow beam: It has high angular resolution for area imaging and target monitoring; high anti-interference performance of narrow beam; high antenna gain; easy to detect small targets and has high accuracy for personnel identification.

[0061] (2) High Doppler frequency: strong anti-interference ability, easy to use the target Doppler frequency characteristics for target feature recognition, and good stability.

[0062] It should also be noted that the touch range of the operator is the range that the operator's arm can reach. More specifically, it refers to the range that the operator's arm can reach when the operator is standing still without tiptoeing or squatting. Displaying virtual buttons within this touch range ensures that the operator can operate the virtual buttons by raising their arm while standing still.

[0063] Furthermore, the body parameters include height parameters, and step S140 specifically includes the following steps:

[0064] Step S141: Based on the height parameters of the passenger being operated, retrieve the corresponding arm parameters from the database;

[0065] Step S142: Determine the touch range of the operating passenger based on the passenger's height parameters, arm length parameters, and position information;

[0066] Step S143: Based on the touch range of the operating passenger, determine the display area within the touch range, and control the touch screen 20 to display the virtual buttons in the display area within the touch range.

[0067] Specifically, the relationship between the passenger's arm reach and height is as follows: Figure 1 As shown, taking the height parameter x of the operating passenger as an example, the shoulder height corresponding to the operating passenger is obtained from the database as 7x / 8 and the arm length as x / 3. Then, the circle with the shoulder position of the operating passenger as the center and the arm length as the radius is the touch range of the operating passenger's arm. Part of the touch screen 20 is located within the touch range of this arm. The touch screen 20 controls the virtual buttons to be displayed in the display area within the touch range of this arm, thereby realizing the purpose of the operating passenger to touch the buttons by simply moving the arm, improving the operating experience of the passenger and reducing accidental touches.

[0068] It should be noted that the height parameter x of the operating passenger refers to the distance from the top of the operating passenger's head to the ground. For example, when the operating passenger is standing, the height parameter x is equivalent to the operating passenger's actual height. When the operating passenger is in a wheelchair, the height parameter x is the height from the top of the operating passenger's head to the floor of the car.

[0069] Furthermore, when the display area cannot accommodate all virtual buttons, a multi-page display method is used to show the virtual buttons within the display area. By employing a multi-page display method, when there are many virtual buttons to be displayed but the display area is small, only some virtual buttons can be displayed within the display area, while other virtual buttons can be displayed by flipping through pages, thus making operation more convenient. It should be noted that the page-flipping method can be swiping or button-based, etc.

[0070] It should also be noted that when the millimeter-wave radar detects that there is no one in the car 10, the touch screen 20 and other devices in the car 10 are in standby mode and the lights are turned off to save energy; when the elevator predicts that there is a floor that needs to be stopped, the touch screen 20 and the lights in the elevator are turned on in advance and enter the working state.

[0071] like Figure 4 The illustrated embodiment two discloses an elevator control method. The elevator includes a car 10, a touchscreen 20, and sensors. The touchscreen 20 has a rectangular structure and is mounted on the inner wall of the car 10. The sensors are millimeter-wave radars, with two radars respectively installed at two opposite corners of the top of the car 10 to ensure there are no blind spots inside the car 10. The millimeter-wave radars can detect the vital signs, body parameters, and position information of passengers inside the car 10. Multiple touchscreens 20 are included, each with multiple display areas for displaying virtual buttons. The elevator control method includes the following steps:

[0072] Step S210: Obtain passenger's body posture information;

[0073] Step S220: Based on the passenger's body posture information, obtain the position information between the passenger and the touch screen 20 corresponding to the body posture information;

[0074] Step S230: Based on the acquired location information, select the passenger closest to the touchscreen 20 from among passengers of the same body type as the operating passenger;

[0075] Step S240: Obtain the body parameters of the passenger being operated on;

[0076] Step S250: Based on the body parameters of the operating passenger, control the touch screen 20 to display virtual buttons in the display area located within the touch range of the operating passenger.

[0077] In this embodiment, by detecting passenger posture information using millimeter-wave radar, it is possible to distinguish between passengers who are standing normally and those who are sitting. Passengers in a sitting position are those using wheelchairs, such as the elderly, wheelchair users, or people with mobility impairments. By differentiating passengers in different postures, the display position of the virtual buttons on the touchscreen 20 can be adjusted accordingly, allowing passengers of all postures to operate the touchscreen 20 and improving user convenience.

[0078] It should also be noted that in this embodiment, millimeter-wave radar is used to acquire the positional information between the passenger and the touchscreen 20. However, this is not limiting. In some other embodiments not shown in the figure, other sensors can be used instead of millimeter-wave radar, as long as they can acquire the positional information between the passenger and the touchscreen 20, such as lidar. Compared with other sensors, millimeter-wave radar is small in size, easy to install and conceal, and does not occupy elevator space. Its millimeter-wave frequency band has high discrimination capability, which can quickly and accurately determine the characteristics of people in the elevator and respond rapidly. Moreover, millimeter-wave radar has strong anti-interference capability and high object filtering resolution, avoiding misjudgment and affecting the elevator's interactive system.

[0079] It should be noted that the touchscreen 20 includes a main touchscreen 21 and a secondary touchscreen 21. The main touchscreen 21 has a rectangular structure and is vertically mounted on the inner wall of the car 10, near the elevator door, for operation by standing passengers. The top of the main touchscreen 21 is positioned at the head level of an adult standing, and the bottom is located near the elevator floor. Multiple display areas for virtual buttons are located between the top and bottom of the main touchscreen 21, allowing operation by passengers of different heights, including adults and children. The secondary touchscreen 21 also has a rectangular structure and is horizontally mounted on the inner wall of the car 10 for operation by wheelchair users. Step S220 further includes the following steps:

[0080] If all passengers are standing, then obtain the position information between all passengers and the main touch screen 21;

[0081] If all passengers are in a seated posture, then obtain the position information between all passengers and the secondary touchscreen 21.

[0082] If all passengers are standing, it means that all passengers in the elevator car 10 are standing. Therefore, the elevator needs to be operated through the main touch screen 21. Thus, it is necessary to obtain the position information between each passenger and the main touch screen 21.

[0083] If all passengers are in a seated position, it means that all passengers in the elevator car 10 are in wheelchairs. Therefore, passengers in wheelchairs need to operate the elevator through the secondary touch screen 21. Thus, it is necessary to obtain the position information between each passenger and the secondary touch screen 21.

[0084] Furthermore, if some passengers are standing and some are sitting, then the position information between all standing passengers and the main touchscreen 21 is obtained, and the position information between all sitting passengers and the secondary touchscreen 21 is also obtained; and step S230 further includes the following steps:

[0085] Based on the obtained passenger location information, among standing passengers, the passenger closest to the main touchscreen 21 is selected as the first operating passenger, and among sitting passengers, the passenger closest to the secondary touchscreen 21 is selected as the second operating passenger.

[0086] Furthermore, step S240 also includes the following steps:

[0087] Obtain the body parameters of the first operating passenger and the body parameters of the second operating passenger; and step S250 further includes the following steps:

[0088] Based on the body parameters of the first operating passenger, the main touch screen 21 is controlled to display virtual buttons in the display area located within the operating passenger's touch range;

[0089] Based on the body parameters of the second operating passenger, the control sub-touchscreen 21 displays virtual buttons in the display area located within the operating passenger's touch range.

[0090] If some passengers are standing and some are sitting, it means that there are both standing and wheelchair users in the car 10. Therefore, it is necessary to obtain not only the position information between the standing passengers and the main touch screen 21, but also the position information between all sitting passengers and the secondary touch screen 21. Among the standing passengers, the passenger closest to the main touch screen 21 is selected as the first operating passenger, and among the sitting passengers, the passenger closest to the secondary touch screen 21 is selected as the second operating passenger. This allows the main touch screen 21 to display the virtual button positions based on the height of the standing passengers, and the secondary touch screen 21 to display the virtual button positions based on the height of the wheelchair users, thus ensuring that both standing and wheelchair users can easily operate on their respective touch screens 20.

[0091] It should be noted that because the main touchscreen is located near the elevator door and in a corner of the car, the space in front of it is limited, making it very difficult for wheelchair users to move their wheelchairs to the front of the screen. By adding a secondary touchscreen, which is positioned further away from the elevator door, wheelchair users have ample space to move their wheelchairs to the side of the secondary screen, avoiding the problem of inconvenient button operation due to limited wheelchair positioning.

[0092] Furthermore, the body parameters include height parameters, and step S240 specifically includes the following steps:

[0093] Step S241: Based on the height parameters of the passenger being operated, retrieve the arm length parameters corresponding to the height parameters from the database;

[0094] Step S242: Determine the touch range of the operating passenger based on the passenger's height parameters, arm length parameters, and position information;

[0095] Step S243: Based on the touch range of the operating passenger, determine the display area within the touch range, and control the touch screen 20 to display the virtual buttons in the display area within the touch range.

[0096] Specifically, if the passenger is standing, the calculation method is the same as in Example 1, and will not be repeated here. If the passenger is in a wheelchair, the relationship between the passenger's arm reach and height is as follows: Figure 4 As shown, taking the height parameter y of the operating passenger as an example, the shoulder height corresponding to the operating passenger is obtained from the database as 3y / 4 and the arm length as y / 2. Then, the circle with the shoulder position of the operating passenger as the center and the arm length as the radius is the touch range of the operating passenger's arm. Part of the touch screen 20 is located within the touch range of this arm. The touch screen 20 controls the virtual buttons to be displayed in the display area within the touch range of this arm, thereby realizing the purpose of the operating passenger to touch the buttons by simply moving the arm, improving the operating experience of the passenger and reducing accidental touches.

[0097] It should be noted that the height parameter y of the operating passenger refers to the distance from the top of the operating passenger's head to the ground. For example, when the operating passenger is standing, the height parameter y is equivalent to the operating passenger's actual height. When the operating passenger is in a wheelchair, the height parameter y is the height from the top of the operating passenger's head to the floor of the car.

[0098] Furthermore, when the display area cannot accommodate all virtual buttons, a multi-page display method is used to show the virtual buttons within the display area. By employing a multi-page display method, when there are many virtual buttons to be displayed but the display area is small, only some virtual buttons can be displayed within the display area, while other virtual buttons can be displayed by flipping through pages, thus making operation more convenient. It should be noted that the page-flipping method can be swiping or button-based, etc.

[0099] It should also be noted that when the millimeter-wave radar detects that there is no one in the car 10, the touch screen 20 and other devices in the car 10 are in standby mode and the lights are turned off to save energy; when the elevator predicts that there is a floor that needs to be stopped, the touch screen 20 and the lights in the elevator are turned on in advance and enter the working state.
