Description

[Technical Field]

[0001] The present invention relates to the technical field of building elevator design optimization, and more particularly to a simulation optimization method for elevator layout in high-rise buildings. [Background technology]

[0002] Elevator design in high-rise buildings is a very important part of building design, directly affecting the building's utilization efficiency and the safety of personnel distribution. However, traditional standards do not clearly define the number of elevators in high-rise buildings. Generally, the number of passenger elevators, apart from fire elevators, is determined by empirical values, which lack scientific basis and are difficult to meet the increasingly complex needs of building functions and utilization.

[0003] Some existing standards provide numerical references for elevator placement. However, these references cannot effectively incorporate dynamic data such as elevator load, operating speed selection, and the number of passengers on each floor, limiting their applicability in actual use. Especially in high-rise buildings, where the number of passengers is large and the distribution is complex, traditional quantitative standards often lack persuasive power when faced with actual demand and cannot adequately respond to actual situations.

[0004] In addition, there is still a lack of effective methods for elevator partition design and number estimation, which means that designers lack scientific basis for decision-making, which affects the rationality of the overall elevator system layout. Previous research proposals also lack the flexibility to flexibly adjust the estimated number of elevators according to changes in building functions, resulting in a lack of design flexibility.

[0005] As described above, in the prior art, due to various problems in elevator layout design and estimation processes, the utilization efficiency of elevator design proposals based on experience often does not match actual demand. Therefore, the object of the present invention is to propose an elevator design optimization method based on actual utilization simulations in order to improve the design rationality and utilization efficiency of elevator systems.

[0021] The present disclosure will be described below with reference to several specific embodiments. In order to maintain clarity and simplicity in the following description of the embodiments of the present invention, the present invention will omit detailed descriptions of known functions and components. Referring to Figure 1, the embodiments of the present invention provide a simulation optimization method for elevator layout in a high-rise building, which includes the following steps:

[0022] S1, acquire building element information including the height of the skirt building, the height of the standard floor, the floors subject to elevator management, and the number of people on the target floors.

[0023] It should be understood that the elevator management floors are floors that need to be covered by the elevator layout plan, for example, in some embodiments, the elevator management floors are floors 4 to 13. The number of people on the target floors may be the maximum number of people that can be accommodated on each floor or on each of several floors at the start of use, which is preset at the building design stage.

[0024] S2, initialize an elevator layout plan including the number of elevators, the management floor area for each elevator, and the elevator parameters for each elevator.

[0025] The elevator layout plan can be initialized based on the conventional criteria and experience to determine the number of elevators to be adopted. The elevator operation times in the simulation of the real scene are T1, T2, and T i··· Then, the operation time and efficiency are calculated for each elevator, and then, based on the evaluation results, it is determined whether the number of elevators n meets the demand and adjusted accordingly. Here, the control floor area of ​​an elevator is the division of the floors that each elevator controls; for example, in the initial elevator layout plan, four elevators are preset, and the control floor area corresponding to elevator No. 1 includes floors 4 to 6, the control floor area corresponding to elevator No. 2 includes floors 7 to 9, the control floor area corresponding to elevator No. 3 includes floors 10 to 11, and the control floor area corresponding to elevator No. 1 includes floors 12 to 13.

[0026] In some embodiments, the elevator parameters include rated speed and passenger capacity, and preferably further include elevator acceleration, and the elevator acceleration may be selected in accordance with Chinese standards, such as the "Elevator Safety Standards", and the elevator acceleration value range is 0.4 m / s 2 ~1.0m / s 2 and in one embodiment of the present invention the value is 0.7.

[0027] S3: Based on the building element information and the elevator allocation plan, an efficiency index including a total transportation time required for each elevator to complete transportation of the maximum number of people in the management floor area corresponding to the elevator is determined.

[0028] In some embodiments, in step S3, Determine the number of stops and equivalent transport height required for the elevator to complete transporting the maximum number of people to its own control floor; Based on the equivalent transport height and the elevator rated speed, the assumed constant speed transport time for the entire process is calculated, and the calculation formula is as follows: t ia =H i / v i , where t iarepresents the assumed constant speed transportation time for the i-th elevator, and H i represents the equivalent transport height of the ith elevator, and v i represents the rated speed of the i-th elevator, Based on the number of stops, the acceleration of the elevator, and the rated speed, the additional transportation time for the acceleration / deceleration movement of the elevator relative to the assumed constant speed transportation time for the entire process is determined, and the calculation formula is as follows: t ib =n i *v i / a, where t ib represents the additional transportation time for the acceleration / deceleration motion of the i-th elevator, and n i represents the number of stops of the i-th elevator, a represents the acceleration of the elevator, Current elevator number estimation algorithms generally assume that elevators operate at a constant speed, ignoring the time it takes for elevators to accelerate and decelerate, which leads to deviations between the calculation results and actual usage. To address the various issues that exist in the elevator number estimation process, the present invention proposes an elevator number optimization plan based on building functions, elevator load, operating speed, and dynamic occupancy distribution to improve the rationality of elevator system design and usage efficiency.

[0029] As shown in Figures 2a to 2d in Figure 2, this formula is determined using the distance-rise equivalent area method. Since the elevator is studying a single floor and the lift height is fixed, the area representing the displacement is a fixed value in a coordinate system with time on the horizontal axis and speed on the vertical axis. Accelerating to half the rated speed and then using the distance decelerated, in the case of uniform acceleration, the shadow of the trapezoid is converted into a rectangular area. Then, by translating the rectangle to the left, the distance increased by acceleration / deceleration is found to be the time required to accelerate to the rated speed in one go.

[0030] In addition, elevators often open their doors repeatedly during actual operation, and the opening time for each door cannot be predicted, especially when there is continuous human traffic dispersion, which increases the inconvenience of using the elevator. Therefore, the door opening time can be optimized through on-site surveys and data collection.

[0031] Based on the number of stops and the predicted time for one door opening and closing, the elevator door opening and closing time is determined, and the calculation formula is as follows: t ic =n i *t0, where t ic represents the door opening / closing time of the i-th elevator, t0 represents the predicted time for one door opening / closing, Based on the assumed constant speed transport time for the entire process, the additional transport time for acceleration / deceleration movement, and the elevator door opening / closing time, the time required for the elevator to complete transporting the maximum number of people in the corresponding management floor area is determined, and the calculation formula is as follows: T i =t ia +t ib +t ic , where T i represents the total transportation time required for the i-th elevator to complete the maximum number of people transported in the control floor area.

[0032] In some embodiments, the step of determining the number of stops required for the elevator to complete a maximum passenger transport for the floor it serves comprises: The method includes a step of calculating an estimated number of elevator stops based on the maximum number of people in the elevator control floor area, the elevator capacity number of people, the elevator occupancy rate, and the number of elevator stops in the elevator control floor area, the calculation formula being expressed as follows:

number

[0033] In actual use, the elevator occupancy rate is usually low, especially when people are carrying luggage. An elevator designed with a rated load cannot meet the actual demand, and large design errors often occur.

[0034] As shown in Table 1 below, in some embodiments, the door opening / closing time and occupancy rate are calculated based on survey statistics of the number of people eating / leaving work during peak hours within three months in an office building. The survey results for the door opening / closing time show that the average time is 6.71 seconds. As can be seen from the survey, the occupancy rate is 89.92%, and since the items people carry are random, the elevator is not always full. Preferably, in some embodiments, more accurate surveys can be conducted for different types of buildings, and more realistic occupancy rates and door opening / closing times can be adopted. Number of stops in a skirt building n q can take on values ​​according to the actual situation, and can take 0 if the function of the skirt building is different from that of the tower building.

[0035] Survey statistics on elevator occupancy rates and door opening and closing times in an office building [Table 1] JPEG0007774763000006.jpg168170

[0036] In some embodiments, an i-th management floor area is defined corresponding to the i-th elevator, and the numbers of each management floor area increase in ascending order.

[0037] The step of determining an equivalent transport height required for the elevator to complete transporting the maximum number of people to the floor it controls comprises: The method includes a step of determining an elevator transport equivalent height based on the estimated number of elevator stops, the height of a skirt building, the height of a standard floor, and the number of floors in a management floor area, and the calculation formula is as follows:

number

[0038] Since the elevator control floor number e1 has not been determined, we assume that the number of people on all floors is concentrated on the central floor of the control area, and that the odd-numbered floors are concentrated on the central plane of the control area (half the height of the central floor), and we can obtain the equivalent height for one operation.

[0039] In one example, a commercial and office building is used. The building has 13 floors, and elevators are mainly used to service the accommodation area from floors 4 to 13. The floor heights are 3.6m, while the heights of the skirt building floors are 4.2m, 4.2m, and 4.5m, respectively. The four elevators mentioned above are used to manage the management floor area divisions from floors 4 to 13. For the elevator layout plan with an elevator rated speed of 2m / s, the calculated results are: Elevator 1 travel time 17.99 points, Elevator 2 travel time 22.97 points, Elevator 3 travel time 12.06 points, and Elevator 4 travel time 13.54 points.

[0040] S4: Based on each of the efficiency indices, the elevator location plan is modified so that the efficiency indices of the modified elevator location plan are better than those of the plan before modification.

[0041] Specifically, if some elevators do not meet the satisfaction requirements, the calculation can be optimized by adjusting the following parameters:

[0042] Elevator product optimization: Improve the elevator rated speed and passenger capacity, and determine it together with cost factors and civil shaft dimensions.

[0043] Building body optimization: Enlarge shaft dimensions, reduce the number of stops, reduce skirt building height, and reduce standard floor height.

[0044] Service partition optimization: When some elevators have slow speeds, the number of floors in the management area and the number of management personnel can be reduced by optimizing the service partition.

[0045] In some embodiments, the step of making the efficiency index of the modified elevator allocation plan better than that before the modification in step S4 includes: The method includes a step of reducing the average value or variance of the total transport time for each elevator. It should be understood that by reducing the variance, the transport time for each elevator can be made closer to each other, and some elevators can be prevented from having their transport times be too long and not meet the demand to some extent, and by reducing the average value, the overall transport efficiency can be improved.

[0046] In some embodiments, the step of making the efficiency index of the modified elevator allocation plan better than that before the modification in step S4 includes: The method includes a step of determining whether the elevators meet the requirements based on a comparison between the efficiency index and a predetermined threshold range, outputting an elevator layout plan if all the elevators meet the requirements, modifying the elevator layout plan if any elevator does not meet the requirements, and returning to re-executing steps S3-S4 until all the elevators meet the requirements and an elevator layout plan is output.

[0047] In some embodiments, the predetermined threshold range is obtained by performing a satisfaction survey statistic.

[0048] Specifically, as shown in Table 2 and Figure 3, in one embodiment, a satisfaction survey is conducted for driving time. In Figure 3, the long lines in each column represent transportation time, and the short lines represent satisfaction scores. Sources of satisfaction include the following: User side: Randomly select pedestrian conversations (with a sample size of 10 or more) during specific time periods (morning peak, meal peak) to calculate the average satisfaction score; Operation and maintenance side: Obtain satisfaction scores by communicating with the heads of the working departments of related institutions; Management side: Obtain satisfaction scores by communicating with related institutions. The ratio of satisfaction survey results is 4:3:3 for User side, Operation and maintenance side, and Management side. Satisfaction scores are ranked as follows, in descending order: 1 - Very dissatisfied, 2 - Dissatisfied, 3 - Generally satisfied, 4 - Satisfied, 5 - Very satisfied.

[0049] Transportation time satisfaction survey statistics [Table 2] JPEG0007774763000009.jpg255159JPEG0007774763000010.jpg255163JPEG0007774763000011.jpg189170

[0050] As can be seen from Figure 3, the basic satisfactory limit is 14.11 minutes and the critical satisfactory limit is 7.90 minutes. In some embodiments, elevators with a predetermined threshold range set to less than 14.11 minutes are elevators that meet the requirements. It should be understood that this preset threshold can be set based on other survey data and demand.

[0051] In some embodiments, the step of modifying the elevator deployment proposal comprises: The method includes the steps of increasing the rated speed and capacity of elevators with high total transit times, and reducing the number of floors and the number of people in the corresponding management floor area.

[0052] Specifically, for example, from the elevator layout plan in the above four elevator example, it can be easily seen that the longest transport time is 22.97 min and the shortest transport time is 12.06, which is generally reasonable. Here, the transport time response of elevator partition No. 2 is long, which can be adjusted by the following two policies:

[0053] The following modifications are possible:

[0054] 1. By improving the elevator speed to 2.5m / s and the elevator load to 18 people, the new result of elevator No. 2 is obtained as 15.03min, and this policy will increase the cost of one elevator by 5%-15% (depending on the elevator brand) and increase the dimension of the building hoistway by 5%-10% (depending on the elevator brand).

[0055] 2. By diverting 1 / 6 of the passengers to elevator No. 3 (by adjusting the building design or usage plan), the new transportation time result for elevator No. 2 is 18.55 min.

[0056] Preferably, in some embodiments, several elevator layout plans may be randomly initialized, and several situations may be formed according to several different building element information, and these may be calculated and evaluated in parallel by the efficiency index calculation method according to the embodiment of the present invention, and a selection may be made based on the calculation results, so that the optimal design plan can be selected according to demand. The method of the present invention can provide a more scientific basis for architectural design.

[0057] In addition, regarding the problem of low vertical transport efficiency in existing high-rise buildings, it is possible to analyze which variable changes will bring about the greatest improvement over the current situation, and improve transport efficiency by means such as adjusting the dimensions of the elevator shaft, increasing the elevator speed and load, and upgrading the elevator door electrical control device.

[0058] The present invention provides a simulation optimization method that is adaptable to actual situations and easy to implement for the traditional elevator layout design, improving the authenticity and rationality of elevator model selection (load, speed) and ensuring the rationality of passenger transport efficiency. The elevator transport efficiency is decomposed into multiple components, and the vertical passenger transport efficiency of a building can be estimated according to different application scenarios and elevator technical parameters, improving the rationality of the evaluation. This provides a scientific basis for planning the number of elevators per partition, facilitating management control.
