Description

Space three-dimensional interactive elevator calling system based on mobile terminal and working method

Technical Field

The invention belongs to the field of van elevator devices, and particularly relates to a space three-dimensional interactive elevator calling system based on a mobile terminal and a working method.

Background

With the continuous evolution of human society, the number of high-rise buildings gradually becomes one of the signs of urban prosperity, and elevators (mainly referred to as van elevators) are indispensable components in the high-rise buildings, so that the elevator technology is rapidly developed. With the increasing of the number and scale of floors of buildings, only one elevator is installed in high-rise buildings and medium-rise buildings to hardly meet the requirement of passenger flow, a plurality of elevators are installed mostly, most of the elevators are in a running state, the elevators form an elevator group, and an elevator group control system is used for uniformly dispatching each elevator in the elevator group. The elevator group control system regards a plurality of elevators as a combination, realizes the analysis of complex passenger traffic flow by using a unified management and coordination mode, and assigns reasonable elevators to complete the transportation task through scheduling optimization. For example, "debye tower" known as "first-rise building of the world" has over 160 floors, with 56 elevators; an elevator 61 is installed on the 88 th floor of the main building of the Shanghai Jinmao building.

With the rapid development and wide application of computers, elevators enter a group control stage in a real sense. And the parameters of the control algorithm are timely adjusted through a computer program. Meanwhile, the system also has a data recording function, and can record and analyze the running state of the elevator, the data of a target floor of a calling floor, the door opening and closing time, the monitoring and recording data of a fault part and the like, so that the aims of fault diagnosis and remote monitoring of an elevator group control system are fulfilled. At present, countries which are in the front of the research field of elevator group control technology in the world mainly comprise the United states and some European countries, OTIS in the United states, schindler in Switzerland, Thyssen Krupp in Germany, Kone in Finland, Mitsubishi in Japan, Hitachi, Toshiba, Fujite and the like are all elevator production enterprises with strong international strength at present. Yutae Lee analyzes the performance of the high-peak elevator system, adopts a stochastic theory aiming at the randomness of the elevator, firstly establishes a semi-Markov chain model of the number of passengers in the elevator system, deduces some important performance indexes of the elevator system by using the model, and simulates the distribution function of the passengers under the conditions of different arrival rates. The Nagatani.T aims at the situation that in actual traffic, the arrival rates of passengers are greatly different at different time intervals, and the situation that the arrival randomness and the arrival bursting performance of the passengers are high occurs in elevator traffic. Aiming at reducing energy consumption, the number of the running elevators and the passenger arrival rate are directly combined to establish a nonlinear mapping model of M elevators. Furthermore, nagatani.t establishes a modified period mapping model of elevator traffic characteristics, studying the dependence of elevator motion on load parameters and passenger flow inflow periods. Meanwhile, the fact that the motion characteristics of the elevator show periodic, aperiodic and chaotic motion along with the change of the operation time of the elevator when the operation speed of the elevator is not constant but variable is researched.

In addition, colleges, research institutes and enterprises are also performing intensive research and development on the group control system. Yan Zhen shan et al carry out the analysis to elevator system group operation, establish the mathematical model of elevator traffic system group component section operation based on optimization theory, this research provides important basis for the design of high-rise building vertical traffic system. Wangztong et al, when building an elevator traffic flow model, propose that the change law of the traffic flow is dense-rare-dense-rare, but the degree of the density and the rare is different with the change of time. Lijunfang carries out qualitative analysis and quantitative description on three flow characteristics of periodicity, randomness and burstiness, and meanwhile, flow prediction models with corresponding characteristics are respectively established from the three flow characteristics, so that a theoretical basis is provided for elevator group control scheduling.

Through the analysis of documents, the conventional group control elevator is simply treated as a simple set consisting of isolated individuals and is uniformly controlled. Such structures tend to have high floor space, high energy consumption and low carrying capacity. For example, in a 60-storey office building with a single floor area, 60 elevators need to be designed and configured, and if a floor-based floor-dividing management technology is used, 25 elevators need to be configured. If a high-speed elevator with the rated load of 1000kg, the speed of 4m/s and the power of 35kw is arranged, the floor of each floor of 1 elevator car of the elevator occupies 9 square meters, and the minimum floor occupies 13500 square meters. And the total power that these elevators need to consume is 875 kw.

In order to overcome the fundamental disadvantages of the existing group control elevator, the Chinese patent: an elevator system, application No.: 201610721723X, and Chinese patent: a hoistway multi-car autonomous transfer elevator system and a working method thereof apply for the numbers: 201710634429X proposes a completely different elevator structure, namely a seven-car structure in a hoistway, compared with the elevator system aimed at by the conventional group control theory. The novel elevator structure greatly saves the problems that the elevator shaft occupies too large area in high-rise buildings and no conversion channel exists between the cars, and greatly improves the elevator operation efficiency under the unit floor area; passengers can transfer in the car, and the transfer time is also saved.

However, for the brand new elevator structure, a plurality of existing elevator group control schemes are not suitable, and a control and dispatching method which can be suitable for the elevator system and can exert the advantages of the elevator system and a device or scheme matched with the control and dispatching method are urgently needed to meet the requirements of commercial operation and market popularization.

Detailed Description

The term is defined as:

call instruction: the steps that a passenger gives an issued call from a call floor to a destination floor, which call is to be executed by the elevator car, include: go to the calling floor to carry passengers, and then go up or down to the destination floor (or transfer floor) to unload passengers.

In this embodiment, for one elevator car, it can execute one call instruction in the process of executing another call instruction, such as: at the floor where the call is executed: 1 to the destination floor: 45, the call floor can also be executed in the process of the up call instruction: 5 to the destination floor: 20, up call instruction. However, according to the scheduling method provided by the embodiment, when the 1- >45 up call instruction is executed, the 20- >5 down call instruction is not received or executed.

An uplink set, a downlink set and a docking set: if the elevator car is in the uplink set, it indicates that one or more call instructions being executed by the elevator car are uplink call instructions, and for the scheduling method provided in this embodiment, it means that all call instructions in the call instruction set executed by the elevator car are uplink call instructions, and do not include downlink call instructions. And the reverse is true for the downlink set.

And the fact that the elevator car is in the stopping set means that at the current moment, the elevator car does not execute an up call instruction or a down call instruction, and the call instruction set executed by the elevator car is empty. For the present embodiment, the elevator car is now in a state to be assigned a call order, and various types of call orders can be accommodated.

In order to make the features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail as follows:

as shown in fig. 1 and 2, the present embodiment is based on a spatial three-dimensional interactive elevator apparatus in which seven elevator cars are disposed in the same hoistway, wherein the seven elevator cars belong to four carrying zones adjacent to each other and arranged in a matrix: car a is in flight zone a, car B1 and car B2 are in flight zone B and car B2 is above car B1, car C1 and car C2 are in flight zone C and car C2 is above car C1, car D1 and car D2 are in flight zone D and car D2 is above car D1; the face of each elevator car facing other elevator cars is provided with a transfer elevator door, and the face facing the outside of the shaft is provided with a connection elevator door.

The main innovation points of the embodiment are as follows: the calling call instruction is input through the mobile terminal and is sent to the elevator dispatching control center; the network entry of the elevator dispatching control center is provided by an information carrier. The mobile terminal is generally a smart phone.

This arrangement is an improvement over conventional elevator vans which are arranged in the interior (comprising a plurality of destination floor selection buttons) and in the exterior (comprising an up or down selection button) of the elevator car.

That is, in this arrangement, the destination floor of the passenger is determined before the passenger enters the elevator car, and even before the system allocates the elevator car, which is different from the conventional elevator call operation mode in which the passenger gives an up-going or down-going call command outside the hoistway, and enters the elevator car and then enters the destination floor.

Based on the setting mode of the embodiment, the calling instruction of the elevator car can be more efficiently and reasonably allocated, so that the efficiency is better compared with the traditional setting mode of the calling device. Meanwhile, the operation of calling the elevator is finished through the mobile terminal, so that convenience is undoubtedly and greatly improved.

In the present embodiment, there are also the following settings:

1. the information carriers are arranged on each floor; the information carrier is a two-dimensional code or a bar code. The arrangement mode can enable the passengers to enter the elevator taking state in the modes of scanning codes and the like on each floor where the passengers need to take the elevator, and is convenient and efficient.

2. The elevator taking scheme is issued to the mobile terminal by the elevator dispatching control center. By the mode, the mobile terminal can be used as a navigation device in the elevator taking process, and passengers can clearly finish the elevator taking and transfer actions according to the prompt of the mobile terminal, so that the situation of taking by mistake is avoided.

3. The call instructions include the destination floor and the number of people boarding the elevator. The elevator car dispatching method has the advantages that the elevator car can be dispatched in advance by fully utilizing the input of the number of passengers taking the elevator, so that the dispatching system can avoid the situation that the elevator is full of passengers in advance according to each call instruction. And the appointed calling call instruction comprising the target floor, the number of people taking the elevator and the elevator taking time is added, so that the advance planning and allocation of elevator car resources can be realized, the ordering of elevator dispatching is facilitated, the elevator taking efficiency is improved for passengers, and the advantage that the mobile terminal is used as an input end and an output end is utilized to the maximum extent.

The working method of the system according to the embodiment comprises the following steps:

For the working method, the embodiment provides a set of scheduling method adapted based on a spatial three-dimensional interactive elevator device with seven elevator cars in the same hoistway, and the method specifically comprises the following steps and flows:

step S1: constructing a set of car carrying sections: dividing the high building into four carrying sections from low to high along the extending direction of the shaft, wherein the car A runs in the first carrying section, the second carrying section, the third carrying section and the fourth carrying section; car B1 is traveling in the first carriage section; car B2 is traveling in the second, third, and fourth carriage sections; car C1 travels in the first carriage section, the second carriage section; car C2 travels in the third and fourth run; car D1 is traveling in the first, second, and third travel sections; car D2 is traveling in the fourth carriage section.

As shown in fig. 2, for the sake of greater clarity, the first carrier section is provided in 1-15 layers; the second carrying section is 16-30 layers; the third carrying section is 31-45 layers; the fourth carrier section is 45-60 layers. It should be noted that the protection scope of the present invention is not limited by the above floor division, and the car carrying sector set can be arbitrarily divided within the rule and allowed range according to the specific situation of the applicable high-rise.

Step S2: building a call instruction set, a car state set and a transfer table, wherein each call instruction is arranged in the call instruction set according to a generation sequence and is divided into an uplink call instruction set and a downlink call instruction set; the call instruction set is generated not only in the central control system of the elevator but also in each elevator car, and the call instruction set of the central control system is used for recording the call instruction triggered by the user, the generation time and the execution condition; while the call instruction set in the elevator car records the instance of the call instruction it is executing and preparing to execute.

The car state set divides the state of each elevator car according to the call command being executed into: an uplink set, a downlink set and a docking set; the transfer table comprises all possible solutions to reach by one transfer of an elevator car when going from a call floor to a destination floor needs to cross more than one carriage sector.

In the present embodiment, a transfer table of 1-60 floors is constructed as shown in table 1, where src denotes a call floor and des denotes a destination floor, and in the table, as [1,15] denotes 1 to 15 floors, that is, a first carriage section; b1 [ A, C1, D1] represents: from any floor of 1-15 floors to any floor of 16-30 floors, the car B1 is an available elevator car of the optional first transfer section, and [ A, C1 and D1] indicate that one of the available elevator cars of the corresponding second transfer section, the car A, the car C1 and the car D1 is optional.

TABLE 1

Step S3: execution of the Call instruction set: for the calling instructions which do not cross the carrying zones, taking one elevator car to complete the boarding according to a preset in-zone priority rule and a car carrying zone set; and for the call instruction crossing the carrying zone, completing the taking after taking one elevator car or performing one-time transfer of the elevator car according to a transfer table according to a preset cross-zone priority rule and the car carrying zone set.

In this embodiment, the available elevator cars that can complete a call without a transfer can be summarized as table 2:

TABLE 2

src denotes the call floor and des denotes the destination floor, in the table, as [1,15] denotes 1 to 15 floors, i.e. the first carriage sector, a, B1, C1, D1 in the table denotes: the elevator cars of the elevator system are all available elevator cars from any floor of 1-15 floors to any floor of 1-15 floors, namely the car A, the car B1, the car C1 and the car D1.

The present embodiment divides the rules of the schedule according to whether transfers are likely to be involved, where intra-zone priority rules do not involve transfers, and cross-zone priority rules involve scheduling of transfers.

As shown in fig. 3, in the present embodiment, the intra-segment priority rule includes the following steps:

step S11: searching whether an available elevator car exists in the car carrying zone set according to the call floor, if not, executing step S13, and if so, executing step S12; if it is desired to go from floor 1 to floor 15, it can be seen from the lookup table 2 that one of the cars a, B1, C1 and D1 can be selected theoretically.

Step S12: according to the fact that the call instruction is ascending or descending, whether an elevator car which is in the same direction set (namely the set where the elevator car is located and the call instruction are both ascending or descending) exists or not is searched in the available elevator cars, and the current position of the elevator car points to the elevator car with the vector direction formed by the call floors and the running direction of the elevator car consistent with the running direction of the elevator car, or whether the elevator car which is in the stopping set exists or not is searched; if not, go to step S13; if the elevator car exists, the elevator car which meets the condition and is closest to the calling floor is selected to execute the calling command.

By the arrangement, the call commands of the uplink and the downlink can be separated, and meanwhile, when a certain elevator executes the call commands, the call commands in the same direction and on the path can be executed in the same way, such as: at the floor where the call is executed: 1 to the destination floor: 45, the execution call floor can be added in the process of the up call instruction: 5 to the destination floor: 20, up call instruction.

In addition, elevator cars (in the stopping set) that are not currently executing call instructions are also optional.

That is, in this embodiment, whether the operating state of the available elevator cars match the call order is the first priority of choice (depending on the actual need, "in the same direction" may also be set and "in the same way" has a higher priority than the stopping set, which may be more energy efficient).

And the distance to the calling floor is taken as a second priority, in the embodiment, the elevator car closest to the calling floor is called preferentially to execute the calling instruction, so that the efficiency is optimal.

Step S13: waits for a preset time T0, and returns to step S11. That is, if there is no elevator car satisfying the conditions of step S11 or step S12, the call command is temporarily not executed, is not assigned to any one of the elevator cars, and waits until an elevator car satisfying the conditions appears. Further, taking the example from floor 1 to floor 15, if all of the car a, the car B1, the car C1, and the car D1 are in the descending set at the time of call command generation, the waiting is performed until any one of the cars is disengaged from the descending set, and the car is selected.

In order to avoid the situation that the passenger waits for the elevator for an unnecessary waiting drag, in step S11, when the distance between a certain available elevator car and the call floor is greater than the preset value M, the available elevator car is rejected. Taking the example from floor 1 to floor 15, when the car a is at floor 60 and in the parking set, although it is in the available state, it is obviously not suitable to dispatch to floor 1, so the exception is eliminated by the exceptional dispatching rule to ensure the efficiency and the economy.

As shown in fig. 4, in this embodiment, the cross-segment priority rule includes the following steps:

the above determination rule is the same as the intra-segment priority rule, and will not be described herein. The difference is that the selection and matching of transfer plans is performed if there are no elevators available that do not need a transfer.

step S25: waiting for a preset time T0, and returning to the step S21;

step S26: and after the available elevator car of the first transfer section executing the call instruction enters the transfer section, the transfer is completed through the available elevator car of the second transfer section corresponding to the transfer table.

That is, the same rules for selection of available elevator cars for the first transfer leg as the intra-zone priority rules.

However, in the transfer rules of the cross-zone priority rules, not only the condition of the first transfer zone but also the condition of the car of the second transfer zone need to be considered, otherwise, reasonable scheduling cannot be realized. Therefore, the following judgment rules are adopted to judge the condition of the elevator car of the second transfer section:

in step S24, if there is an available elevator car of the first transfer floor that meets the determination condition after the search, it is determined whether there is an elevator car of the second transfer floor that meets the availability status corresponding to the transfer table, and if there is no available elevator car of the first transfer floor, the available elevator car of the first transfer floor is regarded as not meeting the determination condition of step S24. That is, if the available elevator cars of a certain first transfer floor satisfy the determination condition of step S24, but the elevator cars of all the corresponding second transfer floors (based on the transfer table) do not satisfy the determination condition, indicating that even if the call command of the first transfer floor can be completed, the appropriate connection cannot be completed in the second transfer floor, and therefore, the option is abandoned.

The method for judging whether the elevator car of the second transfer section meeting the available state corresponding to the transfer table exists specifically comprises the following steps:

step S31: and according to the call instruction set currently received by the available elevator car of the first transfer section to be selected, measuring and calculating the time T1 of the available elevator car of the first transfer section to be selected entering the transfer section, namely estimating the time consumed by the elevator car from the current state to the call floor to finish the elevator taking and then to travel to the transfer section on the assumption that the elevator car receives the call instruction at the current moment.

The transfer section refers to a carrying section in which an area where the transfer can be performed this time is located, and the car B2 descending on the 60-1 floor is executed if necessary: the transfer of car C1, the second carrier sector is the transfer sector, and T1 represents the time spent by car B1 from the current state to crossing 30 floors.

In the aspect of time consumption estimation, the constant speed running, acceleration and deceleration of the elevator car and the stopping time of passengers on and off need to be considered.

Step S32: and according to the call instruction set currently received by the available elevator car of the second transfer section to be selected, calculating whether the condition matched with the transfer of the available elevator car of the first transfer section to be selected can be met in the transfer buffer time T2 after the time T1.

As shown in fig. 5, the specific determination method of whether the transfer buffer time T2 can satisfy the condition of transfer matching with the available elevator car of the first transfer segment to be selected is as follows:

step S33: the transfer buffer time T2 is made to be greater than or equal to the time required for an available elevator car of the first transfer leg to be selected to travel from entering the transfer sector in the direction of the call command to be performed to its carrying sector boundary.

Step S34: and dividing the available elevator cars of the first transfer section to be selected into a virtual car state set according to the instruction direction of the call to be executed (namely, if the call instruction is an uplink, the available elevator cars of the first transfer section are considered to be in an uplink set in judgment, and the same principle is applied to the downlink).

Step S35: and (3) according to the call instruction set currently received by the available elevator car of the second transfer section to be selected, calculating whether the second transfer section to be selected can satisfy the following conditions within the transfer buffer time T2: in the transfer section and belongs to the same direction set with the virtual car state set or in the stopping set.

The meaning of step S33-step S35 is: the limit operation time T2 of the first transfer elevator car in the transfer section is used as a judgment reference (taking the above-described transfer of the car B2 in the 60-1 floor-down: the car C1 as an example, T2, i.e., the time when the car B2 moves down from the 30 th floor to the 16 th floor, including the execution of the call command on the path), and whether the second transfer elevator car can be in a relatively usable state is judged.

The arrangement is considered to be: the first transfer elevator car can theoretically traverse each floor of the transfer section within the time T2, which means that each floor of the transfer section can be used as the actual floor of transfer, and at this time, the second transfer elevator car is satisfied at a certain moment: the elevator car is positioned in the transfer section and is in the same direction as the call instruction, or only needs to be positioned in a parking set, and the time difference (floor difference) between the elevator car of the first transfer section and the elevator car of the second transfer section when the condition is met can be closed by directly allocating the elevator car of the first transfer section and/or the elevator car of the second transfer section. Therefore, the efficiency can be optimized on the premise of finishing transfer.

It should be noted that the time of the judgment reference T2 can also be extended appropriately according to the actual situation, so that more transfer schemes can be matched to obtain, and the elevator peak use pressure can be relieved.

According to the above criteria, a final transfer scheduling implementation scheme can be obtained, as shown in fig. 5, the specific implementation steps of step S28 are:

step S282: according to the measurement of the time T3, the available elevator car of the first transfer section can drive at most a floor L4 after entering the transfer section within the time T3 after T1;

step S283: from the floors L3 and L4, a transfer floor L5 is determined, and the available elevator car of the first transfer floor and the available elevator car of the second transfer floor travel to the floor L5, respectively, as actual transfer floors, and transfer is completed.

The determination mode of L5 can be flexibly set according to specific requirements, such as L5= L3 or L5= L4 can be directly set, and the scheduling scheme of transfer can also be determined according to other criteria, such as determining whether L5 should be biased to L3 or L4 according to the current queuing call instruction condition (i.e. passenger flow pressure) of the first transfer section and the second transfer section. None of these determinations affect the implementation of this embodiment, as the reasonable interval of L5 (i.e., between L3 and L4, including L3 and L4 themselves) has been defined by this embodiment.

Car B2 still descending at 60-1 floor: for example, when the car B2 crosses the 30 th floor, the car C1 is in the ascending set, and when it ascends to the 20 th floor in the time T2, the judgment condition of step S35, that is, L3=20 is satisfied, and at this time, the position L4=22 of the car B2. If the next call command of the car C1 is a down call command, L5=20, and at this time, the car C1 waits slightly at the 20 th floor, the dispatching car B2 continues to travel to the 20 th floor, and the two cars open transfer doors respectively, thereby completing the transfer in the hoistway. Similarly, if the car C1 is in the stopping set at this time, it is also possible to make L5=22, at this time, the car B2 unloads passengers directly at the 22 floors, passengers wait slightly at the 22 floors, and after the car C1 arrives at the 22 floors, the off-hoistway transfer is completed.

In the present embodiment, as the second priority, in step S24, if there are a plurality of elevator cars of the second transfer floor that satisfy the available state, the elevator car of the second transfer floor that satisfies the condition and for which the measured time T3 is shortest is selected to perform the transfer, that is, the elevator car of the second transfer floor that enters the "idle" or "on-road" state most quickly is preferentially selected.

Similar to the intra-sector priority rule, it can also be set that, in step S21, when the distance between a certain available elevator car not requiring transfer and the call floor is greater than the preset value N, the elevator car is rejected to an available elevator car not requiring transfer, so as to ensure the efficiency of the finally executed dispatching plan.

Further, the rules may also extend to the screening of available elevator cars for the first transfer section.

In the present embodiment, the judgment that the elevator car is full is taken as a precondition for whether the call instruction object is included, and if the condition that the elevator car is full is triggered, the elevator car is taken as the highest priority, and the elevator car is not considered as an available elevator car:

if any of the available elevator cars is, for example, in a full state, that elevator car is deemed to be not present when the call command is executed.

The call instruction sets are executed in the order of generation in the up call instruction set and the down call instruction set, respectively, and when a preceding call instruction occupies a certain elevator car, the elevator car is considered to be absent when a subsequent call instruction is executed, even if the boarding operation corresponding to the preceding call instruction is not executed.

On the basis of the above, the device of the embodiment provides the input including the number of passengers in the call command, and the input value can be applied to the judgment of the full-passenger rule.
