Abstract

To provide good transportation services for passengers in the modern buildings, a good elevator group control system (EGCS) is inevitably necessary. The viewpoint of designing the EGCS is very important. Passenger-based viewpoint proposed here provides a new way to think about this system. The capacity constraint following the thoughtfulness consideration for the passengers is utilized to make the performance better. Details of elevator dynamics are modeled to meet the requirements. A traffic database is constructed in order to rebuild the system environment containing information of passengers so that it can be made as close to the real environment as possible. The rescheduling ability is achieved by the new mechanism, which is a priority maker for hall calls. The control policy unit utilizes the traffic database to predict the floors where hall calls will very possibly take place, and parks idling elevators at those floors to reduce passengers' waiting time.

Description

发明 、 Explanation of the invention Material, hybrid H 3 dynamic call assignment unit, a traffic flow collection and processing unit, and a traffic capital ratio. Bu 1 set the elevator and forced to move as early as 70. See Figure 1 for the overall architecture of the system. The legend is mainly divided up and down. From the straight solid line == the actual elevator system ’is the elevator group control system. The traffic flow collection and processing unit will be two, ..., beibei (101), and the conversion result hall will be stored in the traffic database (102). When the real system calls lo / t floors, the environmental simulation unit will simulate the environment by combining the real system and the data mr in the traffic database, and the fitness assessment unit will evaluate the assignment result_, and the evaluation result will be two =: :: Γ is assigned to the decision unit (1 ° 5), and finally the group control system will _, ^ 2). It is expected that the traffic library will also provide information to the intermediary, Zaofan (107), to control the idle elevator in the system _). The detailed description of each unit is as follows. 1. Dynamic Call Assignment Unit Action 70 includes an environmental simulation unit, an assignment suitability assessment and assignment unit, and a call assignment decision unit. w 优 录 uEnvironmental simulation unit A · Elevator model A.1 Elevator movement submodule The group is responsible for controlling the movement behavior of the elevator in the simulation environment unit. The main purpose is to calculate the time it takes for the elevator's position to reach the destination. Different from the traditional calculation, the calculation method here is based on the elevator speed V, the elevator acceleration β, the elevator maximum speed, and the 4 parameters to calculate = interval 0 2 +-•, heart soil + · movement time = < —Case ( a) a 2 soil + 4 \ α 2α2 s v2c-+ — vma, 2av „

Case (b) -—, otherwise Case (c) a a.2 Elevator call placement sub-module This module is responsible for laying the call service behavior of the elevator in the simulated environment unit. Floor materials will be divided into three categories, namely forward, reverse, and backward. The service priority of the elevators for the three categories decreases in descending order. As for the floor call of the radio, the scale of the professional telecom Weida is taken as the priority of service. In addition to arranging the call service sequence of elevators, this module is also responsible for safely moving elevators that are not registered for service calls due to dynamic scheduling, and park safely on nearby floors based on their current position, speed, and acceleration. After secret scheduling, this module will send the new call assignment result to the actual elevator system for execution. In addition to the above functions, this module is used to issue express beer calls to idle elevators and force idle mine elevators to stop at appropriate floors. A. 3 Elevator Floor Service Sub-module This module is responsible for the floor service behavior in the electrical and environmental simulation unit. Different from the traditional fixed service time design ’Here we set the floor service time setting to be linearly proportional to the total number of passengers on the floor service. The total number of passengers on the floor is the number of passengers on the elevator and the number of passengers on the elevator. During the floor service, if the elevator is fully loaded, the elevator will have a strong side door. In addition, this module also considers that the elevator door will be reopened if a passenger arrives at _. B. Floor module Simulate a single μ in the% realm, and the high-rise building is composed of a combination of multi-health teams. Each module counts the privacy of the building, the weight of the passenger, the time of arrival at the floor, and the destination. The passenger's weight is related to the floor of the elevator. The service light is related to 'arrival floor_to calculate passenger waiting time' and the purpose is to determine the in-car call after the passenger = enters the elevator. 1.2 Assignment of fitness assessment unit to determine whenever we need to dynamically schedule the system, we need to evaluate the possible assignment results. The degree of call is pure and detailed-the appropriateness of the tender results. The items are as follows: Passengers waiting for coffee: The time for passengers to enter the elevator is reduced by the time for the passengers to reach the floor. Passenger boarding _: Silk passenger_elevator_ minus the time for passengers to enter the elevator. Power consumption refers to the distance traveled by the elevator. 1225030 The waiting time of unsuccessful passengers · It refers to the passenger waiting for service when the elevator is fully loaded. "Possible waiting time for passengers who are waiting for the service plus a fixed extra time. Each of the above four evaluation items has a weight value of ‘the evaluation value of the entire assignment result is the sum of the four items. Only 1.3 Call Priority Designation Unit Because the traffic conditions in the building are highly volatile, and each change is likely to affect the scheduled results, it is necessary to follow the return situation based on the building status. Fine _ is divided into two phases: the first section of the mine section, the second phase is call assignment, Ben Cui μ is responsible for the first phase of the red crop. Much detailed in this unit. See Step 1: Set up the simulation environment. Step 1. Select the floor call for which the priority record ρ has not been calculated. Step 3. • Cancel all floor calls except the floor call that is being served. Step 4 · Select the elevator y that has not been evaluated. Step 5 ... Calculate the evaluation value c7 of the elevator y. Step 6: Call / assign the floor to the elevator Step 7 ... Calculate the evaluation value c2 of the elevator y. Step VIII-Will-c / § have been described on the floor called z. Monk: No right 5 have recorded Z7!)]. If all elevators have been evaluated, skip to step 9. Otherwise skip back to step three. Step IX: Sort the values of the priority shots of the floor call. And delete by _ for] conversion. You have completed the priority record for floor shots, skip to step 10. Otherwise, skip back to step two. This sorting result is the floor call. Step 10: Sort the priority records of all floor calls in descending order, called the priority order. 1.4 Call Assignment Decision Unit 7 1225030 steps to resolve the result and be assigned to an appropriate elevator to serve. We also break this unit down into numbers. See Figure 9. Step 1: Establish a simulated environment Step 2: Cancel all floor calls except the floor call being served. Step Three ... Select a floor call z that has not been assigned to serve an elevator. Step 4: Select the elevator y that has not been evaluated. Step 5 · Calculate the evaluation value of the elevator /. Step 6: Call / assign the floor to the elevator y ·. Step 7: Calculate the evaluation value c2 of the elevator y. Step 8: Record C2-C / on the floor call, and the evaluation record is still. If all elevators have been evaluated, skip to step 9. Otherwise skip back to step 4. Step 9: Assign the floor call z • to the elevator with the smallest floor. All floor calls have been assigned. Go to step 10. Otherwise skip back to step three. Step 10: Transfer the assignment result to the real elevator system for execution. 2 · Traffic flow collection unit and traffic database In order to establish a simulated environment from the perspective of passengers, we have to search for traffic data in #Building n. This unit is responsible for this -X work. The delivery of materials is mainly divided into two categories—the average arrival rate of passengers on each floor, and the destination floor solution on each floor. This unit contains a three-year age structure to accumulate the number of passengers on each floor 楼层, record the number of guests entering elevator county on each floor (b), and record the number of passengers on other floors of each floor system (C). Below we explain the two data. Collection method. 2.1 The average passenger arrival rate η is actually shot with an elevator «-building materials, building and material calling services, and the flow rate female processing unit will use the elevator device _ to have a sense of weight and estimate. Electricity _ number of passengers, and this The number of people is tired of the data structure. Every time a segment unit is 0H1, the recorded traffic searches for money and materials, divides the accumulated number of people in the money layer by the early coffee, and reduces it to the riding order. 2.2 The probability of the destination floor is easy to explain. Now let the data structure (b) be a two-dimensional array •, and the data structure (C) be a two-dimensional array 8 1225030. All elements in these two arrays are set to the initial value of zero. When true There is an elevator in the system for a floor call service 2. The traffic flow collection processing unit will estimate the number of passengers entering the elevator by means of the weight sensor attached to the elevator device, and call all registered cars at that time ^ • Write this value in When the real system has an elevator to call a certain vehicle in the car, the traffic flow collection processing unit will estimate the number of passengers leaving the elevator by the weight sensor attached to the elevator device, and find out all ^ /] [ 〇 non-zero for all rows with only one non-zero element /,

PcXW] = Pcc [j] [i] + rnin {s [j] [i] 9L} L = L-min {s [j] [ilL} heart ·] [,] = 〇

If Z is still positive, use this number as pcc [j] [n ^ pjj] [n ^ WF] / 'where cctabli Σ heart] [Π: ctable [y] [/ ·]

The elements in the s array after xL are assigned to the remaining floors. The second term to the right of the equal sign in the above formula is to be adjusted according to the following formula. V s [k] [f] nonzero and A: s [k] [V] = s [k] [V] -SW] = 0 Every time & unit time, the traffic flow collection processing unit will link each building to other Cumulative points for floors

The number of assigned persons is divided by the sum of the number of H and points, and this is used as the destination floor probability for each floor of the cafe. ΡαΛβ [ί] = φ ^^

In the LPccUM 6 transportation warehouse, the above two kinds of data are already contained. The unit time can be set according to the characteristics of different high-rise buildings. The reference Lai type can also be adjusted according to the characteristics of high-rise buildings. For example, refer to the previous day, refer to 4 different modes for the previous week. 3. The establishment of passenger perspective simulation environment, U # ^ determination unit and call assignment decision unit We mentioned that the evaluation value is calculated. The evaluation is composed of four evaluation items included in the assigned suitability evaluation unit. Four reviews 9 Waiting passengers need three pieces of information, namely weight, arrival time, and purpose 2. There is a floor call on this floor, then the time of registration is expected to be the benchmark. Otherwise, the time of day_benchmark_Qiantong Information Pinchta speed turns to generate passengers. The ground floor is determined by the probability of the destination floor based on traffic information. 3.2 Passengers boarding an elevator Passengers also need three pieces of information, namely weight, time of entering the elevator and destination. The same as waiting for passengers on the floor. This is how the other two materials are created. We will use the elevator = reset sensor to estimate the number of passengers in the elevator. Then use the second type of data storage structure according to the traffic flow collection sheet to find all the rows with non-zero elements, and assign the number of passengers according to the numerical proportion of these rows as the probability to assign 'passengers entering the elevator_, that is, set to true The time of the elevator's most recent stop on the floor. The destination floor of the passenger is determined by the probability of the destination floor in the warehouse. -Once the simulation environment has been established, ‘we can evaluate the passenger waiting time, passenger rides, etc.’ and other evaluation items ’, and the evaluation value obtained in this way will be closer to the real situation, and the assignment result will be improved. 4. The function of the forced moving unit of the idle elevator The traffic database can be used to reward the occurrence of floor calls in our system. Below we explain how this unit works. Preparation Steps: Whenever transportation costs change with time, Xian will use the average arrival rate of passengers on each floor to calculate the electric power of each floor. The calculation method is ___ average passenger arrival rate divided by the average arrival rate of the whole building, the total number of elevators in the county. For floors where the number of elevators on the floor is less than i ', if the total number of floor elevator reservations in consecutive sections exceeds 丨, the midpoint floor of the section will obtain the right to reserve an idle elevator. Sort the floors with elevator reservations greater than zero in descending order. 1225030 When the elevator becomes idle due to the end of service, the idle elevator forces the mobile unit to perform the following steps. Step 1: Perform dynamic scheduling Step 2: If there is no elevator ·, the process ends. Otherwise, go to step three. · Step 3: Select-one idle elevator. If there are no idle elevators, the process ends. Step 4: According to the order of the floors in the preparation step, obtain a floor with an elevator that has not yet been saturated. Step 5. Designate the idle elevator to stop at the floor. Skip back to step three. In this way, the staircase can be parked in advance on the floor where the floor call may occur, so as to shorten the waiting time of passengers. See Figure 11. Graphic description Figure 2 This figure is an example of _ different moving modes of the elevator. Figure ⑻ shows that the elevator is too close to the destination floor, so it needs to move in the opposite direction after deceleration. This situation only occurs when the elevator only has one call registered. The graph () shows the situation where the elevator is advancing at an accelerated speed, but it has not been added to the maximum speed. The diagram (c) shows the situation where the elevator is advancing at an acceleration and accelerating to the maximum speed.

This figure illustrates the efficiency benefits that can be gained by a more precise consideration of elevator service time. If judged by a fixed service time, the traditional group control system will assign the left elevator to the seventh floor for service, but this is an incorrect assignment because the elevator will spend a lot of time on the fifth floor, and our system can detect this , And dispatch the right elevator to the seventh floor service. This figure illustrates the performance benefits that can be gained by considering elevator passenger capacity. If the current passenger capacity of the elevator is not considered, the traditional group control system will assign the left elevator to the third floor service because it is closer, but this is an incorrect assignment because the elevator is already fully loaded and our system is due to consideration Elevator capacity will be assigned to the right elevator. 11 1225030 Figure 5 The brother-in-law τ, the brother of Fanpu, who is sad and sad. Left _ is called |, and another sakura floor calls, at this time the group control system Fang elevator goes to service. If a new floor is called for printing, 4 | ° is as shown on the right. At this time, in order to provide two floors with good service quality at the same time, the previous assignment result must be changed to the seventh floor. ， ° 使 县 杂 五 _Right Electricity must illustrate the low-level advantages of designing group control _ Kexian from. First of all, Na does not consider waiting for passengers and only evaluates with axons. _ Tong Qun Control Wei will make Rugao's assignment. However, based on overall efficiency considerations, it should be assigned to the right gate, and the number of counties should be _. Interpretation_. On the left, most passengers want to go to the fifth floor, while a few passengers want to go to the seventh floor, while the right elevator is in the opposite state. The peaks of the material peaks are as follows, such as Xie Yi, Qi Nian Da elevator to the sixth floor services, such as rewards will delay electricity _ number of passengers arrived on the seventh floor _, _ _ __ passengers in the car to make the allocation as shown on the right. -This figure illustrates the efficiency advantages of Lai Traffic Database. First explain _. If you do not test the arrival rate of the county passengers, the traditional group «Unification will make the assignment on the left, but because the fifth floor of the county is high, the assignment is closer to the ladder to go to the service. Chance. In the middle of the picture, the third-floor silk guest wants to miscellaneous the seventh floor, and the fourth-floor silk guest wants to misunderstand. The traditional group control system will make the assignment as shown on the left without the information of the destination floor, and our system has mastered Destination floor information 'can make more appropriate assignments to reduce passenger waiting time and boarding time. Figure 10 This figure illustrates the performance benefits of predicting possible floor calls. The picture on the left shows the traditional group control system. When the elevator service is completed, it will stay in its original position, and the elevator will not start moving until the floor is called for registration. In our secret, when the elevator is forced, the elevator will force the scale shifter to send the elevator to the appropriate floor according to the arrival rate of the passengers on the floor, so the waiting time of the passengers can be reduced. 12 1225030 Brief description of the diagram Figure 1 is the overall architecture diagram of the system. Figure 2 shows the different elevator moving modes considered in the elevator moving sub-module. Figure 3 illustrates the performance advantages that can be brought into consideration in the elevator floor service sub-module by considering elevator service time and number of passengers served. Figure 4 illustrates the performance benefits that can be gained by considering elevator capacity constraints. Figure 5 illustrates the importance of dynamic scheduling capabilities in response to environmental changes. Figure 6 illustrates the efficiency benefits that can be brought by designing a group control system from the passenger's perspective.
