Description

TECHNICAL FIELD

[0001] The present application relates to the elevator technical field, and in particular to an elevator dynamic adjustment method and system, a computer device and a readable storage medium. BACKGROUND

[0002] As an indispensable vertical transportation tool in modern urban buildings, the comfort and reliability of elevator operation have always been the focus of attention. The sound environment in the car is an important parameter for measuring passenger comfort. For passengers, a quiet and comfortable car environment can improve the riding experience and reduce irritation and discomfort.

[0003] In an elevator system, components such as hoisting machines and cars are provided with exhaust devices to dissipate heat and exchange air. These exhaust devices produce sound when running, and this part of the sound is transmitted to the car interior and is one of the important sources of car noise. Therefore, effectively controlling the sound produced by components such as hoisting machine fans and car fans is of great significance to improving the overall ride comfort of the elevator.

[0004] Currently, most exhaust devices such as hoisting machine fans and car fans on the market use a constant speed working mode, that is, as long as the elevator is in operation, the exhaust fan will continue to run at a fixed speed. Although this traditional working mode can meet the basic heat dissipation and air exchange needs of the elevator to a certain extent, it lacks flexibility and cannot be dynamically adjusted according to the actual elevator car position and the specific situation inside the car, affecting the passenger's ride experience.

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0053] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0054] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0055] In a preferred embodiment of the present invention, based on the above-mentioned problems existing in the prior art, a dynamic adjustment method and system for an elevator are provided. When applied to the operation of the elevator, the fan speed of the exhaust system in key components such as the traction machine and the car can be dynamically adjusted to achieve the multiple goals of energy saving, noise reduction and comfort improvement.

[0056] like Figure 1 As shown, the elevator system includes a car 1, a traction machine 2, a car fan 3, a traction machine fan 4, and an electronic monitoring device 5. The car fan 3 is installed on the car 1, the traction machine fan 4 is installed on the traction machine 2, and the electronic monitoring device 5 is installed on the top of the car 1.

[0057] like Figure 2 As shown, the elevator dynamic adjustment method includes:

[0058] Step S1: Obtain the elevator car position X, the number of passengers in the car N, and the decibel level D of the passengers' voices in real time;

[0059] The elevator car position X can be obtained using the hoisting machine encoder and the car leveling mark. The hoisting machine encoder records the rotation of the hoisting machine. By counting the pulses of the hoisting machine encoder, the approximate travel distance and position of the elevator can be obtained. Combined with the car leveling mark, the real-time position of the elevator car can be determined.

[0060] The number of passengers N in the elevator car can be obtained via the electronic monitoring device 5. The electronic monitoring device 5 includes a visual signal acquisition component for identifying incoming passengers. To improve recognition accuracy and reliability, the visual signal acquisition component preferably utilizes a high-definition camera equipped with infrared sensing and object posture recognition capabilities. Its operation is as follows: when the infrared function of the HD camera detects human movement, it immediately activates the visual system. By tracking and identifying the person's specific posture, it can determine whether a passenger has entered the elevator car and the specific number of passengers N in the elevator car.

[0061] The passenger's voice decibel level (D) can also be obtained through the electronic monitoring device 5. The electronic monitoring device 5 also includes a signal acquisition component for identifying human voices and detecting their level. To more accurately capture human voice information, a decibel meter configured to capture specific frequencies and harmonic energy of human voices is preferably used. Its operation is as follows: When the decibel meter captures characteristic data of human voices with frequencies between 85Hz and 300Hz, and harmonic energy concentrated between 300Hz and 4kHz, it records the level of the captured sound signal (in decibels), which is the passenger's voice decibel level (D).

[0062] Step S2, adjusting the speed of the traction machine fan according to the position of the elevator car;

[0063] Step S3: adjusting the speed of the car fan according to the number of passengers in the car and the decibel level of the passengers' voices.

[0064] Specifically, this embodiment dynamically adjusts the speed of the hoist fan 4 based on the distance between the elevator car position X and the hoist by monitoring the elevator car position X, the number of passengers N in the car, and the decibel level D of the passengers' voices in real time. When the car 1 is close to the hoist, the speed of the hoist fan 4 is appropriately reduced, thereby reducing the noise level of the hoist fan 4 and the noise transmitted into the car 1, thereby improving the passenger experience.

[0065] At the same time, under the premise of ensuring smooth air circulation based on the number of passengers N in the car, the speed of the car fan 3 is dynamically adjusted according to the decibel D of the passengers' voices, thereby controlling the noise level generated by the rotation of the car fan 3. The noise generated by the fan is masked by the sound made by the passengers, reducing the passengers' perception of the fan noise and improving riding comfort.

[0066] The embodiment of the present invention dynamically adjusts the rotation speed of the traction machine fan 4 and the car fan 3 by real-time monitoring of the elevator car position X, the number of passengers in the car N, and the decibel level D of the passengers' voices, thereby controlling the noise level generated by the fan rotation, thereby improving the passenger riding experience while ensuring the safe operation of the elevator.

[0067] As a preferred embodiment, wherein Figure 3 As shown, step S2 includes:

[0068] Step S21, determining whether the distance between the elevator car position and the elevator traction machine position exceeds a preset threshold, and executing step S22 if it exceeds the preset threshold, and executing step S23 if it does not exceed the preset threshold;

[0069] Step S22, adjusting the rotation speed of the traction machine fan 4 to a first preset rotation speed V11;

[0070] In step S23 , the rotation speed of the traction machine fan 4 is adjusted to a second preset rotation speed V12 , wherein the second preset rotation speed V12 is lower than the first preset rotation speed V11 .

[0071] Specifically, first, a threshold value of the position of the car 1 from the hoisting machine 2 is set: when the distance between the car and the hoisting machine does not exceed a preset threshold value L, the position is set as the threshold position X'.

[0072] The rotation speed of the hoisting machine fan 4 is set to V1.

[0073] During actual operation, the speed of the traction machine fan 4 is dynamically adjusted based on the comparison of the collected value of the elevator car position X with the threshold position X'. When the car is close to the traction machine, the speed of the traction machine fan 4 is appropriately reduced, thereby reducing the sound generated by the traction machine fan 4 and ultimately reducing the noise transmitted to the car.

[0074] When the collected value of the elevator car position X exceeds the threshold position X', the distance between the car and the hoist is relatively large. At this point, the speed of the hoist fan 4 is dynamically adjusted to the first preset speed V11. At this speed, the noise generated by the hoist fan 4 is D1, which meets the requirements for heat dissipation and ventilation. Although the noise D1 is relatively loud, the long distance has little impact on the interior of the car.

[0075] When the collected value of the elevator car position X is less than or equal to the threshold position X', it indicates that the distance between the car and the traction machine is relatively close. At this time, the speed of the traction machine fan 4 is dynamically adjusted to the second preset speed V12, V12 <V11。该转速下曳引机风扇4产生的噪音为D2,D2<D1,能够降低风扇产生的噪音,从而减少传递到轿厢内的噪声,提升乘客的乘坐舒适性。

[0076] It should be noted that the specific values ​​of the preset threshold value L, the threshold position X′, the first preset rotational speed V11 and the second preset rotational speed V12 can be set according to actual needs and are not limited here.

[0077] As a preferred embodiment, a plurality of passenger threshold intervals are preset corresponding to the number of passengers in the car, a plurality of decibel threshold intervals are preset corresponding to the decibel of the passenger voice in each passenger threshold interval, and each decibel threshold interval corresponds to a preset speed;

[0078] like Figure 4 As shown, step S3 includes:

[0079] Step S31, determining a corresponding passenger threshold interval based on the number of passengers in the car obtained in real time;

[0080] Step S32, determining a corresponding decibel threshold interval and a corresponding preset speed based on the determined passenger threshold interval and the real-time acquired passenger voice decibels;

[0081] Step S33: adjusting the speed of the car fan according to the preset speed corresponding to the determined decibel threshold range.

[0082] Specifically, in this embodiment, the speed of the car fan is dynamically adjusted based on the number of passengers N in the car and the decibel level D of the passengers' voices, so as to further optimize the environment in the car and enhance the passengers' riding experience.

[0083] Specifically, multiple passenger threshold intervals are pre-set for the number of passengers N in the car, and within each passenger threshold interval, multiple decibel threshold intervals are correspondingly set for the passenger sound decibel D, and each decibel threshold interval corresponds to a preset speed.

[0084] During actual operation, after obtaining the number of passengers in the car in real time, it is compared with the pre-set passenger threshold range to determine the specific passenger threshold range in which the current number of passengers is located.

[0085] After determining the passenger threshold range, combined with the real-time passenger voice decibels, the decibel threshold range in which the current passenger voice decibel is located is further determined among the multiple decibel threshold ranges corresponding to the passenger threshold range, and the corresponding preset speed is found to dynamically adjust the speed of the car fan 3.

[0086] As a preferred embodiment, wherein Figure 6 As shown, the passenger threshold interval includes a first passenger threshold interval (N≤A), a second passenger threshold interval (A<N≤B)和第三乘客阈值区间(N> B);

[0087] In the first passenger threshold interval (N≤A), the decibel threshold interval includes a first decibel threshold interval (D≤a1), a second decibel threshold interval (a1<D≤a2)和第三分贝阈值区间(D> a2); wherein the first decibel threshold interval (D≤a1) corresponds to the first speed V21, and the second decibel threshold interval (a1<D≤a2)对应于第二转速V22,第三分贝阈值区间(D> a2) corresponds to the third speed V23;

[0088] In the second passenger threshold interval (A <N≤B)内,分贝阈值区间包括由第三分贝阈值a3、第四分贝阈值a4划分形成的第四分贝阈值区间(D≤a3)、第五分贝阈值区间(a3<D≤a4)和第六分贝阈值区间(D> a4); wherein the fourth decibel threshold interval (D≤a3) corresponds to the fourth speed V24, the fifth decibel threshold interval (a3<D≤a4)对应于第五转速V25,第六分贝阈值区间(D> a4) corresponds to the sixth speed V26;

[0089] In the third passenger threshold interval (N>B), the decibel threshold interval includes a seventh decibel threshold interval (D≤a5), an eighth decibel threshold interval (D≤a5) formed by dividing the fifth decibel threshold a5 and the sixth decibel threshold a6.<D≤a6)和第九分贝阈值区间(D> a6); wherein the seventh decibel threshold interval (D≤a5) corresponds to the seventh speed V27, the eighth decibel threshold interval (a5<D≤a6)对应于第八转速V28,第九分贝阈值区间(D> a6) corresponds to the ninth speed V29.

[0090] Specifically, in this embodiment, passenger number thresholds A, B, and C are set, and the passenger number distribution range is divided into several passenger threshold intervals from 0 to A to B to full load, where C represents full load; and at the same time, the car fan speed is set to V2.

[0091] For different passenger threshold ranges, the corresponding decibel thresholds of passenger voices are set, namely:

[0092] In the interval N≤A, set the first decibel threshold a1 and the second decibel threshold a2;

[0093] In the range of A<N≤B, the third decibel threshold a3 and the fourth decibel threshold a4 are set;

[0094] In the interval B<N (or B<N≤C), the fifth decibel threshold a5 and the sixth decibel threshold a6 are set.

[0095] During actual operation, the number of passengers N in the car and the decibel level D of the passengers' voices are obtained in real time and compared with a preset range to determine the corresponding rotation speed of the car fan 3.

[0096] Specifically, when N≤A and D≤a1, the rotation speed of the car fan 3 is adjusted to the first rotation speed V21;

[0097] When N≤A and a1<D≤a2, the rotation speed of the car fan 3 is adjusted to the second rotation speed V22;

[0098] When N≤A and a2<D, the rotation speed of the car fan 3 is adjusted to the third rotation speed V23, wherein the first rotation speed V21 is less than the second rotation speed V22, and the second rotation speed V22 is less than the third rotation speed V23.

[0099] When A<N≤B and D≤a3, the speed of the car fan 3 is adjusted to the fourth speed V24;

[0100] When A<N≤B and a3<D≤a4, the speed of the car fan 3 is adjusted to the fifth speed V25;

[0101] When A<N≤B and a4<D, the rotation speed of the car fan 3 is adjusted to the sixth rotation speed V26, wherein the fourth rotation speed V24 is less than the fifth rotation speed V25, and the fifth rotation speed V25 is less than the sixth rotation speed V26.

[0102] When B<N and D≤a5, the speed of the car fan 3 is adjusted to the seventh speed V27;

[0103] When B<N and a5<D≤a6, the speed of the car fan 3 is adjusted to the eighth speed V28;

[0104] When B<N and a6<D, the rotation speed of the car fan 3 is adjusted to the ninth rotation speed V29, wherein the seventh rotation speed V27 is less than the eighth rotation speed V28, and the eighth rotation speed V28 is less than the ninth rotation speed V29.

[0105] While ensuring smooth air circulation within the cabin, the embodiments of the present invention dynamically adjust the cabin fan speed based on the number of passengers N and the decibel level D of their voices. When passengers are speaking loudly, the fan speed is appropriately increased. Because the passengers' voices can mask the fan noise, the passenger's perception of fan noise is reduced, improving passenger comfort.

[0106] Furthermore, the first speed V21 is less than the fourth speed V24, the fourth speed V24 is less than the seventh speed V27; the second speed V22 is less than the fifth speed V25, the fifth speed V25 is less than the eighth speed V28; the third speed V23 is less than the sixth speed V26, the sixth speed V26 is less than the ninth speed V29.

[0107] It should be noted that the specific values ​​of the above-mentioned first passenger threshold A, second passenger threshold B, first decibel threshold a1, second decibel threshold a2, third decibel threshold a3, fourth decibel threshold a4, fifth decibel threshold a5, sixth decibel threshold a6, first speed V21, second speed V22, third speed V23, fourth speed V24, fifth speed V25, sixth speed V26, seventh speed V27, eighth speed V28, and ninth speed V29 can be set according to actual needs and are not limited here.

[0108] In addition, the above-mentioned passenger threshold, decibel threshold and corresponding interval division are only examples and are not limited to this. In actual applications, the passenger threshold, decibel threshold and corresponding interval division can be increased or decreased as needed and the speed corresponding to each interval can be set.

[0109] In a preferred embodiment of the present invention, a dynamic adjustment system for an elevator is also provided. Figure 6 Shown, including:

[0110] Data acquisition unit 6, used to obtain the elevator car position, the number of passengers in the car, and the decibel level of passengers' voices in real time;

[0111] The traction machine fan control unit 7 is connected to the data acquisition unit 6 and is used to adjust the speed of the traction machine fan 4 according to the position of the elevator car;

[0112] The car fan control unit 8 is connected to the data acquisition unit 6 and is used to adjust the speed of the car fan 3 according to the number of passengers in the car and the decibels of the passengers' voices.

[0113] Specifically, in this embodiment, by real-time monitoring of the elevator car position, the number of passengers in the car, and the decibels of the passengers' voices, the rotation speed of the traction machine fan and the car fan is dynamically adjusted, thereby controlling the noise level generated by the fan rotation, thereby improving the passenger riding experience while ensuring the safe operation of the elevator.

[0114] During the operation of the elevator, the position of the car keeps changing. When the car rises, it gradually approaches the traction machine; when the car descends, it gradually moves away from the traction machine.

[0115] The elevator car position X is collected through the traction machine encoder and the car leveling mark.

[0116] When the car 1 approaches the traction machine 2 and the elevator car position X satisfies X≤X', the speed of the traction machine fan 4 is reduced to the first preset speed V11 while ensuring normal heat dissipation of the traction machine. By reducing the fan speed, the noise generated by the traction machine fan 4 and transmitted to the car is reduced, thereby creating a quieter car riding environment.

[0117] When the car 1 moves away from the traction machine 2 and reaches the elevator car position X satisfying X>X', the traction machine fan speed is increased to the second preset speed V12 to give priority to enhancing the heat dissipation of the traction machine.

[0118] When a passenger enters the cabin, an electronic monitoring device monitors the number of passengers. While ensuring adequate air circulation, the cabin fan speed is adjusted based on the number of passengers. If the cabin is lightly populated, the speed of cabin fan 3 is appropriately reduced to minimize noise; if the cabin is heavy, the speed is appropriately increased.

[0119] Furthermore, after determining the number of passengers in the cabin, the electronic monitoring device also collects the decibel level of the passengers' voices, thereby more precisely controlling the speed of the cabin fan 3. For example, when the passengers in the cabin are relatively quiet or their voices are relatively low, the fan speed will be appropriately reduced to prevent the fan noise from becoming a disturbing factor. Conversely, when the passengers in the cabin are slightly louder, the speed will be appropriately increased, using the passengers' voices to mask the sound generated by the fan operation, thereby reducing the passengers' perception of fan noise.

[0120] By continuously and uninterruptedly monitoring the status of the car and passengers, the system can dynamically adjust the speed of equipment such as the traction motor fan and car fan in real time, so that the passengers in the car can perceive the sound in the optimal state, greatly improving the passenger comfort while ensuring basic requirements such as traction motor heat dissipation and ventilation in the car.

[0121] As a preferred embodiment, the traction machine fan control unit 7 includes:

[0122] A judgment module 71 is used to judge whether the distance between the elevator car position and the elevator traction machine position exceeds a preset threshold and output a judgment result;

[0123] a first adjustment module 72 connected to the judgment module 71 and configured to adjust the rotation speed of the traction machine fan 4 to a first preset rotation speed when the judgment result indicates that the distance between the elevator car position and the elevator traction machine position exceeds a preset threshold;

[0124] The second adjustment module 73 is connected to the judgment module 71 and is used to adjust the speed of the traction machine fan 4 to a second preset speed when the judgment result indicates that the distance between the elevator car position and the elevator traction machine position does not exceed the preset threshold, wherein the second preset speed is less than the first preset speed.

[0125] Specifically, a threshold value of the distance between the car 1 and the traction machine 2 is preset in the judgment module 71. When the distance between the car 1 and the traction machine does not exceed the preset threshold value L, the position is set as the threshold position X'.

[0126] The module also sets the rotation speed of the traction machine fan 4 to V1.

[0127] During actual operation, the speed of the traction machine fan 4 is dynamically adjusted based on the comparison of the collected value of the elevator car position X with the threshold position X'. When the car is close to the traction machine, the speed of the traction machine fan 4 is appropriately reduced, thereby reducing the sound generated by the traction machine fan 4 and ultimately reducing the noise transmitted to the car.

[0128] When the collected value of the elevator car position X exceeds the threshold position X', the distance between the car and the hoist is relatively large. At this point, the speed of the hoist fan 4 is dynamically adjusted to the first preset speed V11. At this speed, the noise generated by the hoist fan 4 is D1, which meets the requirements for heat dissipation and ventilation. Although the noise D1 is relatively loud, the long distance has little impact on the interior of the car.
