Description

Technical Field

[0001] The invention belongs to the technical field of building elevator design optimization, and in particular relates to a high-rise building elevator layout simulation optimization method. Background Art

[0002] The elevator design of high-rise buildings is a very important part of architectural design, which directly affects the efficiency of building use and the safety of personnel evacuation. However, the current regulations do not give clear regulations on the number of elevators in high-rise buildings. Usually, except for fire elevators, the number of ordinary passenger elevators is mostly based on empirical values. This empirical value lacks scientific basis and is difficult to meet the increasingly complex building functions and usage requirements.

[0003] Some existing standards provide quantitative references for elevator configuration. However, these references fail to effectively combine dynamic data such as elevator load, operating speed selection, and the number of people on each floor, resulting in limited applicability in actual use. Especially in super-high-rise buildings, due to the large number of users and complex distribution, the existing quantitative standards are often unconvincing when facing actual needs and cannot fully respond to actual conditions.

[0004] In addition, there is still a lack of effective means for the zoning design and quantity estimation of elevators, and designers lack scientific basis when making decisions, which affects the rationality of the overall configuration of the elevator system. Existing research schemes are also unable to flexibly adjust the number of elevators according to changes in building functions, resulting in insufficient design flexibility.

[0005] In summary, the prior art has many problems in the estimation process for the layout design of elevators. The utilization efficiency of elevator design solutions based on experience often does not match the actual needs. The purpose of the present invention is to propose an elevator design optimization method based on simulation of actual usage conditions to improve the design rationality and utilization efficiency of the elevator system.

[0046] The present disclosure is described below through several specific embodiments. In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits the detailed description of known functions and known components. Figure 1 The embodiment of the present invention provides a high-rise building elevator layout simulation optimization method, comprising the following steps:

[0047] S1. Acquire building element information, where the building element information includes podium height, standard floor height, elevator management target floor, and number of people on the target floor.

[0048] It should be understood that the elevator management target floor is understood as the floor that the elevator arrangement needs to cover, for example, in some embodiments, the elevator management target floor is 4 to 13 floors. The number of people on the target floor can be the maximum number of people that can be accommodated on each floor or every few floors when it is put into use according to the preset architectural design stage.

[0049] S2. Initialize an elevator layout plan, where the elevator layout plan includes the number of elevators, the floor area that each elevator is responsible for, and elevator parameters of each elevator.

[0050] The initialization of the elevator layout plan can be based on the current standards and experience to preliminarily determine the use of n elevators, whose running times in the real scene simulation are T1, T2, T i··· , and carry out running time calculation and efficiency evaluation work one by one, and then determine whether the number of elevators n meets the demand and make adjustments based on the evaluation results. The floor area of ​​the elevator is the division of the elevator management target floor by each elevator. For example, in an initial elevator layout plan, 4 elevators are preset. The floor area corresponding to elevator No. 1 includes floors 4 to 6, the floor area corresponding to elevator No. 2 includes floors 7 to 9, the floor area corresponding to elevator No. 3 includes floors 10 to 11, and the floor area corresponding to elevator No. 1 includes floors 12 to 13.

[0051] In some embodiments, the elevator parameters include a rated speed and a rated full load. Preferably, the elevator acceleration is also included. The selection of the elevator acceleration can be based on national standards such as the "Elevator Safety Specifications". The elevator acceleration value should range from 0.4 m / s² to 1.0 m / s². In one embodiment of the present invention, the value is 0.7.

[0052] S3. Determine an efficiency index of each elevator according to the building element information and the elevator layout plan, wherein the efficiency index includes a total transportation time required for the elevator to transport a maximum number of people in the corresponding floor area.

[0053] In some embodiments, in step S3:

[0054] Determine the number of stops and equivalent transport height required for the elevator to transport the maximum number of people on the floors it is responsible for;

[0055] Based on the equivalent transport height and the rated speed of the elevator, the transport time assuming a uniform speed throughout the journey is calculated as follows:

[0056] ,in represents the assumed uniform speed transportation time of the ith elevator. represents the equivalent transport height of the i-th elevator, represents the rated speed of the i-th elevator;

[0057] Based on the number of stops, the acceleration of the elevator and the rated speed, the additional transportation time of the acceleration and deceleration movement caused by the acceleration and deceleration movement of the elevator relative to the assumed uniform speed transportation time throughout the entire journey is determined, and the calculation formula is expressed as:

[0058] ,in represents the additional transportation time of the acceleration and deceleration motion of the i-th elevator, represents the number of stops of the i-th elevator, and a represents the acceleration of the elevator;

[0059] The current elevator quantity estimation algorithm generally assumes that the elevator runs at a constant speed, ignoring the time consumed by the elevator acceleration and deceleration, which further leads to the deviation between the calculation result and the actual usage. Therefore, in view of the various problems existing in the process of elevator quantity estimation, this paper proposes an elevator quantity optimization scheme based on building function, elevator load, running speed and dynamic distribution of personnel to improve the design rationality and utilization efficiency of the elevator system.

[0060] like Figure 2 middle Figure 2 a~ Figure 2 d, this formula is determined by the lifting distance equivalent area method, taking a single floor as the research object, and the elevator lifting height is fixed, so in the coordinate system with time as the horizontal axis and speed as the vertical axis, the area representing the displacement is a fixed value. Take the distance of acceleration and deceleration to half of the rated speed, and under uniform acceleration, the trapezoidal shadow can be converted into a rectangular area, and then the rectangle is translated to the left, and it can be found that the distance increased due to acceleration / deceleration is the time required for one-time acceleration to the rated speed.

[0061] At the same time, elevators often open their doors repeatedly during actual operation. Especially when the flow of people is continuously distributed, the time of each door opening cannot be predicted, which increases the inconvenience of using the elevator. The single door opening time can be optimized through on-site surveys and data collection.

[0062] The elevator door opening and closing time is determined based on the number of stops and the estimated time for a single door opening and closing. The calculation formula is expressed as:

[0063] ,in represents the opening and closing time of the door of the i-th elevator, Indicates the estimated time of a single door opening and closing;

[0064] Based on the assumed uniform transportation time throughout the entire journey, the additional transportation time for acceleration and deceleration, and the elevator door opening and closing time, the time required for the elevator to complete the transportation of the maximum number of people in the corresponding floor area is determined, and the calculation formula is expressed as:

[0065] ,in It represents the total transportation time required for the i-th elevator to transport the maximum number of people in the floor area it is responsible for.

[0066] In some embodiments, determining the number of stops required for an elevator to transport the maximum number of people on a floor for which the elevator is responsible includes:

[0067] The estimated number of elevator stops is calculated based on the maximum number of people in the elevator's floor area, the elevator's rated full load, the elevator's full load rate, and the number of stops in the podium. The calculation formula is:

[0068] ,in Table 1 Estimated number of stops for the i-th elevator, Indicates the maximum number of people in charge of the i-th floor area, represents the rated full load of the i-th elevator, k represents the elevator load rate, Indicates the number of times the podium stops.

[0069] In actual use, the full load rate of the elevator is usually low, especially when people are carrying goods. Elevators designed according to the rated load often cannot meet actual needs, resulting in large design errors.

[0070] As shown in Table 1 below, in some embodiments, the single door opening and closing time and full load rate are calculated based on the survey statistics of the number of people dining / getting off work during the peak period of three months in a certain office building. The survey result of the single door opening and closing time is an average time of 6.71 seconds. After investigation, it is known that the full load rate is about 89.92%. Since the items carried by people are random, the elevator will not be fully loaded every time. Preferably, in some embodiments, targeted surveys can be conducted on different types of buildings, and more realistic full load rates and door opening and closing times can be adopted. Number of stops at the podium The value can be determined according to the actual situation. If the function of the podium is different from that of the tower, the value can be 0.

[0071] Table 1 Survey statistics on elevator load rate and door opening and closing time in an office building

[0072]

[0073]

[0074] In some embodiments, it is defined that the i-th elevator corresponds to the i-th floor area in charge, and the serial numbers of the floor areas in charge increase from low to high;

[0075] Determine the equivalent transport height required for the elevator to transport the maximum number of people on the floors it is responsible for, including:

[0076] The elevator transportation equivalent height is determined based on the estimated number of elevator stops, podium height, standard floor height and number of floors in the responsible floor area. The calculation formula is expressed as:

[0077] ;

[0078] ;

[0079] in represents the elevator transportation equivalent height of the i-th elevator, represents the equivalent height of a single transport of the i-th elevator, Indicates the height of the podium. Indicates the standard floor height. Indicates the number of floors included in the i-th floor area.

[0080] Since the number of floors e1 that the elevator is in charge of is uncertain, it is assumed that the number of people on all floors is concentrated on the middle floor of the area in charge, and the number of people on the odd-numbered floors is concentrated on the middle plane of the area in charge (half the height of the middle floor), so that the equivalent height of a single operation can be obtained.

[0081] In one embodiment, a commercial-office complex is taken as an example, the building has 13 floors, of which the elevator is mainly used for the 4F-13F accommodation area, with a floor height of 3.6m, and the podium floor heights are 4.2m, 4.2m, and 4.5m respectively. Using the above-mentioned 4 elevators in charge of the 4th to 13th floors, under the elevator layout scheme with a rated speed of 2m / s, the calculation results are: the transportation time of elevator No. 1 is 17.99 minutes; the transportation time of elevator No. 2 is 22.97 minutes; the transportation time of elevator No. 3 is 12.06 minutes; and the transportation time of elevator No. 4 is 13.54 minutes.

[0082] S4. Modify the elevator arrangement plan based on the efficiency indicators so that the efficiency indicator of the modified elevator arrangement plan is better than that before the modification.

[0083] Specifically, if some elevators do not meet the satisfaction requirements, the calculation can be optimized by adjusting the following parameters:

[0084] Elevator product optimization: increase the rated speed of the elevator, increase the rated full load, and further determine it based on cost factors and civil engineering shaft size factors.

[0085] Building optimization: expand the shaft size, reduce the number of stops, reduce the height of the podium, and reduce the height of the standard floor.

[0086] Service zone optimization: If the speed of some elevators is slow, the service zones can be optimized to reduce the number of floors and the number of people in charge.

[0087] In some embodiments, making the efficiency index of the modified elevator arrangement scheme better than that before the modification in step S4 includes:

[0088] The average value or variance of the total transportation time of each elevator is reduced. It should be understood that reducing the variance will make the transportation time of each elevator closer, which will avoid the transportation time of some elevators being too long and not meeting the demand to a certain extent, while reducing the average value can improve the overall transportation efficiency.

[0089] In some embodiments, making the efficiency index of the modified elevator arrangement scheme better than that before the modification in step S4 includes:

[0090] Whether the elevator meets the requirements is determined based on the comparison between the efficiency index and the preset threshold range. If each elevator meets the requirements, the elevator layout plan is output; if there is an elevator that does not meet the requirements, the elevator layout plan is modified, and steps S3-S4 are returned to be re-executed until each elevator meets the requirements and the elevator layout plan is output.

[0091] In some embodiments, the preset threshold range is obtained by conducting satisfaction survey statistics.

[0092] Specifically, for example, Table 2 and Figure 3 As shown, in one embodiment, a satisfaction survey on the running time is conducted. Figure 3 The long line in each column represents the transportation time, and the short line represents the satisfaction score. The sources of satisfaction include: users, randomly select pedestrians for dialogue during a specific time period (morning rush hour, dining peak) (the number of samples is not less than 10), and take the average of the satisfaction values; the operation and maintenance party, dialogue with the person in charge of the logistics unit of the relevant agency to obtain the satisfaction value; the management party, dialogue with the relevant agency to obtain the satisfaction value. The satisfaction survey results are as follows: users: operation and maintenance party: management party = 4:3:3. Satisfaction is divided from high to low: 1-very dissatisfied, 2-unsatisfied, 3-basically satisfied, 4-relatively satisfied, 5-very satisfied.

[0093] Table 2 Statistics of Transportation Time Satisfaction Survey

[0094]

[0095]

[0096]

[0097]

[0098] Combination Figure 3 It can be seen that the basic satisfaction limit is 14.11 minutes, and the very satisfactory limit is 7.90 minutes. In some embodiments, the preset threshold range is set to an elevator less than 14.11 minutes as an elevator that meets the requirements. It should be understood that the limited threshold can be set according to other survey data and requirements.

[0099] In some embodiments, the modifying the elevator arrangement includes:

[0100] For the elevator with a higher total transport time, the rated speed and the rated full load are increased, and the number of floors and the number of people in the corresponding floor area are reduced.

[0101] Specifically, for the elevator layout plan of the above 4 elevators, it is not difficult to find that the longest transportation time is 22.97 minutes and the shortest transportation time is 12.06, which is relatively reasonable overall. Among them, the partition transportation time response of elevator No. 2 is relatively long, which can be adjusted through the following two strategies

[0102] The following modifications can be made:

[0103] 1. Raise the elevator speed to 2.5m / s and the elevator load to 18 people, and the new result for Elevator 2 is 15.03min. This strategy will increase the cost of a single elevator by 5%-15% (depending on the elevator brand) and expand the size of the civil engineering shaft by 5%-10% (depending on the elevator brand).

[0104] 2. Divert 1 / 6 of the transport passengers to Elevator No. 3 (through architectural design or usage planning adjustments), and the new transport time for Elevator No. 2 is 18.55 minutes.

[0105] Preferably, in some embodiments, several elevator layout schemes can be randomly initialized, and multiple situations can be formed by combining multiple different building element information, and the efficiency index calculation method provided by the embodiment of the present invention can be calculated and evaluated in parallel, and then the optimal design scheme can be selected according to the calculation results. The method of the present invention can provide a more scientific basis for building design.

[0106] In addition, in response to the problem of low vertical efficiency of existing high-rise buildings, we can analyze which variable changes will have the greatest improvement on the current situation, and improve transportation efficiency by adjusting the size of the elevator shaft, increasing the elevator speed and load, and upgrading the elevator door electronic control device.

[0107] The embodiment of the present invention provides a simulation optimization method that fits the actual situation and is easy to implement for the existing elevator layout design, improves the authenticity and rationality of elevator selection (load, speed), and ensures the rationality of personnel transportation efficiency. By breaking down the elevator transportation efficiency into multiple components, a method for estimating the vertical personnel transportation efficiency of a building can be used according to different application scenarios and elevator technical parameters, thereby improving the rationality of the evaluation. A scientific basis for planning the number of elevator zoning units is formed, which is convenient for management and control.
