Description
Technical Field
The invention relates to the field of elevators, in particular to an elevator group management method for group management of a plurality of elevators.
Background
The elevator often encounters sporadic large passenger flows in the actual operation process, and the sporadic large passenger flows are random, so that measures for dealing with large passenger flows in preset time (whether self-identified on-duty peak passenger flows or large passenger flows caused by deterministic events of property management input) in the traditional group management algorithm cannot be effectively dealt with.
For example, for a museum, after a short peak of entry into the museum when the door is opened in the morning, a period of smooth passenger flow with relatively small passenger flow is entered, and only when a team visitor arrives, the passenger flow entering the museum is instantly increased to a very high level. Because the arrival time of the team visitors is random, the elevator group management algorithm cannot predict the change condition of elevator passenger flow, and cannot make effective correspondence. Further, the following scenario may occur: when a plurality of elevators finish the transportation of passengers, the elevators directly stop at the original places (usually some landings far away from a bottom building hall), at the moment, a visiting team of 40 persons arrives, team visitors need to take the elevators to reach a certain floor for collective visit after passing through an entrance gate, after the bottom building is registered, an elevator group management system generally responds to a bottom building calling request and dispatches an elevator to go to the bottom building, but the number of the team visitors far exceeds the rated passenger carrying number of one elevator (for example, the rated passenger carrying number is 21 persons), after the response elevator arrives at the bottom building, an ascending registration button is turned on and turned off, the team visitors continuously enter the elevator car (the ascending registration button cannot be operated in the process that the visitors enter the elevator car, otherwise, the door is opened reversely in the process of closing the door), and after the number of the visitors entering the elevator car reaches 21 persons, the elevator is fully closed and started to leave. At this point, the remaining visitors need to re-register uplinks and the elevator group management system again assigns elevators to floor call requests. Therefore, in the process, the team visitor needs to wait for the elevator twice and register for ascending twice at the longest, which seriously affects the elevator boarding experience and visiting experience of the visitor (the visitor arriving at the visiting floor first needs to wait for the visitor of the next elevator for a long time).
It is clear that for the aforementioned sporadic high traffic, existing elevator group management systems are not able to effectively identify and allocate sufficient elevators in time to cope with.
Disclosure of Invention
The invention aims to provide an elevator group management method, which can solve the problems of long waiting time of passengers, low conveying efficiency and poor passenger experience when the conventional elevator group management system processes sporadic large passenger flows.
In order to solve the above problems, the present invention provides an elevator group management method, wherein when an elevator stops at a landing and opens a door for passengers to enter the car, if the following conditions are satisfied simultaneously, it is determined that sporadic large passenger flow occurs at the landing, and an elevator group management system dispatches at least one redundant elevator to the landing, and all elevators dispatched to the landing run in the same direction:
condition C1, at time k 1 The car load rate of the elevator which is stopped at the landing and is used for the elevator waiting passengers to enter the car reaches a first set threshold value alpha;
condition C2, the elevator groupThe management system stores a running time range of a deterministic big-passenger-flow mode for dealing with the deterministic big-passenger-flow, and the time k 1 Outside the run time range.
Further, at least one of the following conditions is also simultaneously true:
condition C3, there is one at time k 1 Previous time k 2 In a time period [ k ] 2 ，k 1 ]The car load rate of the elevator having stopped at the landing for the waiting passengers to enter the car is continuously increased, and k 1 ﹣k 2 Beta is more than or equal to beta, wherein beta is a positive real number;
and C4, before the car load rate of the elevator stopped at the landing and allowing the elevator waiting passenger to enter the car reaches a first set threshold α, the utilization rate of the transport capacity of the elevator group controlled by the elevator group management system does not exceed a second set threshold γ.
Further, the following conditions are satisfied simultaneously:
condition C5, the redundant elevator dispatched by the group management system is in an idle state before being dispatched.
Further, the time that the redundant elevator is in an idle state before being dispatched is larger than a third set threshold value delta.
Further, when the elevator group management system determines to re-dispatch the redundant elevator, the prompt message containing the operation information of the dispatched redundant elevator and/or the information of the redundant elevator is generated and output.
Further, when the elevator which has stopped at the landing and allows the elevator waiting passenger to enter the car leaves the landing before the redundant elevator arrives at the landing, the direction information registered at the landing is kept displayed.
Further, the elevator group management system judges whether the landing is a landing which is likely to have sporadic large passenger flow according to the attribute information of the floor where the landing is located.
Further, after the elevator group management system finishes the transportation of the large passenger flow in a mode of dispatching the booster elevators, the related information is recorded, and whether the large passenger flow is real sporadic is verified through the recorded result.
Further, when the elevator group management system verifies through the recorded result that the large passenger flow transported by the redundant elevator is real sporadic large passenger flow, the elevator group management system analyzes whether a rule exists on the occurrence floor of the sporadic large passenger flow and/or the number distribution of passengers, and if so, adjusts the first set threshold value alpha according to the rule.
Further, the elevator group management system analyzes whether a rule exists on the occurrence floor of sporadic large passenger flow and/or the number distribution of passengers, and if so, the number of the rescue elevators is determined according to the rule.
Compared with the prior art, the invention can achieve the following beneficial effects:
firstly, the elevator can be allocated to the current floor in advance before the elevator car is detected to be fully loaded, so that the allocated elevator can reach the current floor earlier, and the elevator waiting time of passengers can be effectively shortened;
secondly, the invention automatically reserves a registration signal for the passenger needing to take the subsequently distributed redundant elevator without re-registering, thereby simplifying the passenger operation and improving the passenger taking experience;
thirdly, when the target floors of the sporadic large-passenger-flow passengers are the same, the waiting time of the passenger who arrives at the target floor first to wait for the passenger who arrives later can be shortened, and the riding experience of the passenger is improved;
fourthly, the invention can verify the large passenger flow after finishing the large passenger flow transportation, and can further adjust the dispatching time and the number of the assistance-increasing elevators according to the occurrence floor and/or the distribution regularity of the number of passengers when the large passenger flow is verified to be sporadic, thereby further improving the riding experience of the passengers.
Detailed Description
The following description of the embodiments of the present invention is provided by way of specific examples, and other advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure herein. In the following description, specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced or applied in different embodiments, and the details may be based on different viewpoints and applications, and may be widely spread and replaced by those skilled in the art without departing from the spirit of the present invention.
Example one
In the elevator group management method of the embodiment, when one elevator stops at a landing and is opened for a passenger to enter the car, if all conditions in any one of the following condition groups are simultaneously satisfied, the elevator group management system judges that accidental heavy passenger flow occurs at the landing, the elevator group management system dispatches at least one booster elevator to the landing, and all elevators dispatched to the landing run in the same direction, wherein the first condition group consists of a condition C1 and a condition C2, the second condition group consists of a condition C1, a condition C2 and a condition C3, the third condition group consists of a condition C1, a condition C2 and a condition C4, the fourth condition group consists of a condition C1, a condition C2, a condition C3 and a condition C4, the fifth condition group consists of a condition C1, a condition C2 and a condition C5, the sixth condition group consists of a condition C1, a condition C2, a condition C3 and a condition C5, the seventh condition group consists of a condition C1, a condition C2, a condition C4 and a condition C5, and the eighth condition consists of a condition C1, a condition C2 and a condition C5;
condition C1, at time k 1 The car load rate of the elevator which is stopped at the landing and is used for the elevator waiting passengers to enter the car reaches a first set threshold value alpha;
condition C2, the elevator group management system stores the operating time range of the deterministic traffic pattern for the deterministic traffic, time k 1 Outside the run time range;
condition C3, there is one at time k 1 Previous time k 2 In a time period [ k ] 2 ，k 1 ]The car load rate of the elevator having stopped at the landing for the waiting passengers to enter the car is continuously increased, and k 1 ﹣k 2 Beta is more than or equal to beta, wherein beta is a positive real number;
a condition C4 that the utilization rate of the transport capacity of the elevator group controlled by the elevator group management system (i.e., the ratio of the current passenger transport amount of the elevator group to the maximum transport capacity thereof) does not exceed a second set threshold γ before the car load factor of the elevator stopped at the landing for the waiting passenger to enter the car reaches a first set threshold α;
condition C5, the redundant elevator dispatched by the group management system is in an idle state prior to being dispatched.
This embodiment can be in advance for current floor allocation elevator before detecting elevator car and reaching full load for the elevator that is allocated can arrive current floor earlier, consequently can shorten passenger's the ladder time of waiting effectively.
Further, the time that the redundant elevator is in an idle state before being dispatched is greater than a third set threshold value delta.
The conditions C4 and C5 mainly limit the application of the elevator group management method of this embodiment to a time period when the elevator is relatively idle, so that even if the judgment of sporadic large passenger flow is incorrect, the whole transport efficiency of other passengers and the elevator group is not significantly affected.
And when the elevator group management system determines to dispatch the redundant elevators, generating and outputting prompt information containing the operation information of the dispatched redundant elevators and/or the information of the redundant elevators.
When the elevator, which has stopped at the landing and has the elevator waiting passenger entering the car, leaves the landing before the redundant elevator arrives at the landing, the direction information registered at the landing is kept displayed. Therefore, the registration signal can be automatically reserved for the passenger needing to take the subsequently distributed booster elevator, the passenger does not need to register again, the passenger operation is simplified, and the passenger taking experience is improved.
The landings are landings where sporadic large passenger flows are likely to occur. And the elevator group management system judges whether the landing is a landing which is possible to have sporadic large passenger flow, such as a bottom floor hall, a conference room layer, a movie theater layer and the like according to the attribute information of the floor where the landing is located.
When the target floor of the sporadic large-passenger-flow passenger is the same, the waiting time of the passenger who arrives at the target floor first to wait for the passenger who arrives subsequently can be shortened by the embodiment, and the riding experience of the passenger is improved.
Example two
In addition to the first embodiment, in this embodiment, after the elevator group management system completes the transportation of the current large passenger flow by dispatching a redundant elevator, the elevator group management system records the relevant information, which mainly includes the occurrence floor, the occurrence time, the actual number of passengers, the duration time, and the like of the large passenger flow.
Since the information related to the aforementioned conditions is limited and there is a possibility of misjudgment, it is possible to verify whether the mass flow is a real sporadic mass flow by using the recorded results (in combination with the operational data of the booster elevator).
When the elevator group management system verifies that the large passenger flow transported by the aid elevator is real sporadic large passenger flow through the recorded result, the elevator group management system analyzes whether a rule exists on the occurrence floor of the sporadic large passenger flow and/or the passenger number distribution, and if so, adjusts a first set threshold value alpha according to the rule.
The larger the first set threshold alpha is, the later the moment when the elevator group management system dispatches the booster elevator is; the smaller the first set threshold value alpha, the earlier the moment the elevator group management system dispatches a redundant elevator. For example, the number of people waiting for the elevator is small (for example, the number of people does not exceed 5) sometimes and large (for example, the number of people exceeds 10) sometimes in sporadic passenger flow on a certain floor, and the rated number of people carrying the elevator is 10, so that the increased-assistance elevator can be dispatched when the number of people in the elevator car is judged to exceed 8 according to the load of the elevator car, and the early increased dispatch can be realized, so that the waiting time of passengers needing to take the increased-assistance elevator can be shortened.
In a place where the number of people is large although the number of people is sporadically large, such as a hall of 1 st floor in a museum, for example, the first threshold value α may be set to be small so that the rescue elevator can arrive as early as possible. In other places where occasional large passenger flows occur but the number of passengers is not particularly large, in order to avoid misassignment of the enhanced elevator, the threshold α may be set to be slightly larger, for example, the maximum passenger capacity of the elevator is 20, the number of passengers is 33, and when the first set threshold α is set to 0.6, the elevator group management system assigns a first enhanced elevator and then assigns a second enhanced elevator, but actually does not need the first enhanced elevator, and when the first set threshold α is set to 0.8, the elevator group management system assigns the first enhanced elevator but does not assign the second enhanced elevator.
The elevator group management system analyzes whether the passenger number distribution of the occurrence floor of the sporadic large passenger flow has a rule or not, and if so, the number of the rescue elevators is determined according to the rule.
For example, in a 1-floor lobby of a museum, if the number of team visitors is approximately equal each time, the number of rescue elevators required can be calculated according to the number of visitors and the maximum number of passengers capable of being loaded in the elevator. For other floors, such as a show hall, the number of the reinforcement elevators required for transporting the audience can be calculated according to the number of seats of the show hall and the maximum number of passengers capable of carrying the elevator.
The present invention has been described in detail with reference to the specific embodiments, which are only preferred embodiments of the present invention, and the present invention is not limited to the above embodiments. Equivalent alterations and modifications made by those skilled in the art without departing from the principle of the invention should be considered to be within the technical scope of the invention.
