Description

Elevator destination floor allocation method

Technical Field

The present invention relates to elevator destination floor allocation, and more particularly, to an elevator destination floor allocation method capable of coping with a situation in which an elevator user stays.

Background

Generally, elevators provide two ways for elevator users to register a request for boarding: one is that the passengers input the elevator taking direction information to the elevator by pressing the buttons in the corresponding direction by utilizing the up-down buttons arranged in the elevator waiting hall; the other method is that the passenger inputs the destination floor information to the elevator by using the destination floor registration device or the mobile terminal of the passenger in the elevator waiting hall. The group management system of the elevator can realize more efficient and reasonable allocation by using the destination floor information input by the passenger, so in recent years, the group management system which is provided with a destination floor registration device in a waiting hall or uses a personal mobile terminal of the passenger to input the destination floor information and adopts the destination floor information based on the passenger to allocate the elevator group is more widely applied.

At present, a group management system based on passenger destination floor information assumes that all elevator waiting passengers can register destination floor information, and all elevator waiting passengers can take the elevator after the elevator arrives. In fact, however, a plurality of passengers having the same destination floor may register only once, which may cause a part of passengers not to get into the elevator car and to stay in the elevator hall when the elevator is fully loaded. In addition, it may happen that passengers refuse to take the current elevator because of congestion in the suspected car. When passengers are detained due to full load, congestion and the like, the conventional group management system based on the destination floor information of the passengers cannot effectively and reasonably deal with the detained passengers.

In order to solve this problem, chinese patent application publication No. CN111137762A proposes that, when it is determined that all cars traveling to a destination floor (input from a destination floor registration device in a hall) are full, all cars are output to a hall display device. Therefore, the technical scheme of the application only provides information notification of full elevator cars for passengers, and does not solve the problem of how to deal with the full elevator cars by the group management system.

Therefore, it is a problem to be solved to provide a destination floor allocation method that can deal with the situation where passengers are not able to get in an elevator car due to full car or the like and stay in a landing.

Disclosure of Invention

The invention aims to provide a destination floor allocation method capable of dealing with the situation that passengers can not be loaded into an elevator car due to full load of the elevator car and the like and stay on a landing.

In order to solve the problems, the invention provides an elevator destination floor allocation method, which comprises the following steps:

step S1, receiving destination floor information from elevator users;

step S2, allocating the elevators by adopting an elevator group management method based on the destination floor information, and outputting allocation results to elevator users;

and 2, after the elevator car finishes getting on or off the passenger, the difference value between the weighing result of the elevator car weighing device and the rated load capacity of the elevator car is less than or equal to a first set threshold value alpha.

In a further improvement, in step S5, when the elevator car stops at the registered floor and the elevator users going to get off the car do not leave the car, if the sum of the remaining number of passengers that can be taken by the elevator car and the number of elevator users who will leave the car at the registered floor is less than the number of elevator users waiting to take the elevator at the landing where the registered floor is located and whose elevator taking direction is expected to coincide with the elevator car running direction, it is determined that the elevator user detention phenomenon occurs at the registered floor.

In a further improvement, the step S5 determines the remaining number of passengers of the elevator car according to any one of the following manners:

mode 1, the remaining loadable mass of an elevator car is obtained by using the weighing result of an elevator car weighing device, and then the remaining loadable mass and the standard weight of a common passenger are converted into the remaining number of passengers of the elevator car;

mode 2, the remaining available area of the elevator car is obtained by using an image recognition mode, and then the number of the remaining available passengers of the elevator car is converted into the number of the remaining available passengers of the elevator car according to the remaining available area and the standard car floor projection area occupied by the general passengers for taking the elevator.

In a further improvement, in step S5, when the elevator car stops at the registered floor and the elevator user going to get off does not leave the car, if the sum of the remaining available area of the elevator car and the actual occupied area of the elevator user leaving the car at the registered floor in the car is smaller than the required occupied area of the elevator user waiting for boarding at the landing where the registered floor is located and expecting the boarding direction to be consistent with the running direction of the elevator car, it is determined that the elevator user staying phenomenon occurs at the registered floor.

In a further improvement, the required occupied area of an elevator user waiting for the elevator to be taken at the landing where the registered floor is located and desiring to take the elevator in the direction consistent with the running direction of the elevator car is obtained by any one of the following methods:

the method comprises the following steps that 1, calculation is carried out according to the number of different registered destination floors or the total number of registered passengers and the standard car floor projection area occupied by general passengers to board an elevator;

mode 2, the identification is obtained according to the identity information of the elevator user, wherein the identity information contains the content of the occupied area for taking the elevator.

In a further development, the remaining available space of the elevator car is obtained in any of the following ways:

mode 1, according to the image recognition result in the elevator car;

in the mode 2, for all elevator users who get in and out of the elevator car, the occupied area required when the users take the elevator is detected when the users get in and out of the elevator car, the actual occupied area of the elevator car is calculated, and the occupied area is obtained according to the total area of the elevator car and the actual occupied area of the elevator car;

and in the mode 3, for the elevator users in the elevator car, the occupied area required for the elevator to take is identified according to the identity information of the elevator users, the actual occupied area of the elevator car is calculated, and the actual occupied area is obtained according to the total area of the elevator car and the actual occupied area of the elevator car, wherein the identity information contains the content of the occupied area required for the elevator to take.

In a further improvement, when the ratio of the actual occupied area of the elevator car to the total area of the elevator car exceeds a second set threshold β, the step S5 determines that the registered floor has an elevator user retention phenomenon.

In a further improvement, in step S5, it is determined whether or not the registered floor is in an elevator user retention state based on an influence factor affecting the elevator user to take the elevator and a corresponding threshold value. The method comprises the following specific steps:

In a further improvement, in the step a3, the possibility that the elevator user stays at the destination floor to be processed is judged according to the remaining available resources of the elevator car which is driven away from the registered floor to the destination floor to be processed or stopped at the registered floor but the elevator user has completed the elevator getting on and off, and the required resources of the destination floor to be processed.

A further improvement is characterized in that the original allocation result is retained when at least one of the following conditions is true:

condition 1, the number of elevator taking requests of the elevator which finishes the transportation of passengers in the elevator car in the current running direction and is served by the allocated elevator taking requests in the running direction of the elevator going to the floor where the detained elevator users are located again is less than a third set threshold value;

condition 2, the distance between the floor where the detained elevator user is located and the farthest target floor in the current running direction of the elevator is smaller than a fourth set threshold;

condition 3, the waiting time required for the detained elevator users or the elevator users not responding to the elevator taking request to be transported by other elevators is longer than the waiting time for the original elevator to finish the transportation of passengers in the elevator car and return to the transportation after the allocated elevator taking request is served;

condition 4, the overall operating efficiency of the elevator group remains unchanged.

The further improvement is that the required resources for stopping at the target floor to be processed are estimated and determined according to the total number of people registered at the floor, the number of the registered target floors and historical data.

condition 2 is that the difference between the weighing result of the weighing device of the elevator car and the nominal load capacity of the elevator car after the end of the boarding and disembarking of the elevator car (closing of the elevator car door) is less than or equal to a first set threshold value α, which is usually less than the weight of one passenger, e.g. 50 kg.

Second mode

When the elevator car stops at the registered floor and the elevator users going off the elevator car do not leave the elevator car, if the sum of the number of the remaining passengers of the elevator car and the number of the elevator users going off the elevator car at the registered floor is less than the number of the elevator users waiting for the elevator at the landing of the registered floor and expecting the elevator to have the same elevator taking direction as the running direction of the elevator car, the phenomenon that the elevator users are detained at the registered floor is judged.

Wherein the remaining number of persons that can be picked up in the elevator car is determined in any one of the following manners:

EXAMPLE III

In addition to the first embodiment, the present embodiment will further describe in detail various ways of determining the destination floor of the elevator user staying at the registered floor and the destination floor of the elevator user riding in the car from the registered floor in step S6.

First way-elevator users riding in the car register their destination floors again

Specifically, the elevator user who gets into the car from the registered floor is prompted to register the destination floor by the in-car floor registration device, and the destination floor of the elevator user who gets into the car from the registered floor is obtained based on the registration result. The destination floor of the elevator user staying at the registered floor is determined according to the destination floor registered by the elevator user and received by the destination floor registration device on the landing of the registered floor and the destination floor of the elevator user taking the car from the registered floor.

The car floor registration device provides only destination floor registration options registered by an elevator user, which are received by a destination floor registration device at a landing of the registered floor. For example, there are 1 to 10 floors in total, and when the destination floors registered by the elevator users received by the destination floor registration device on the landing are 8, 9, and 10, the in-car floor registration device (usually, a touch screen) provides only the registration options of 8, 9, and 10.

And further, providing the obtained destination floor of the elevator user staying at the registration floor to the staying elevator user for confirmation or modification, or simultaneously prompting the staying elevator user to confirm or modify.

Second way-the detained elevator user registers his destination floor again

Specifically, the elevator user who stays at the registered floor is prompted to register the target floor again by using the target floor registration device on the landing, and the target floor of the elevator user who stays at the registered floor is obtained based on the registration result. And determining the destination floor of the elevator user taking the elevator car from the registered floor according to the destination floor registered by the elevator user and the destination floor of the elevator user staying at the registered floor received by the destination floor registration device on the landing of the registered floor.

Further, the obtained destination floor of the elevator user who gets into the car from the registered floor is provided for confirmation or modification of the elevator user who gets into the car from the registered floor, or the confirmation or modification of the elevator user who gets into the car from the registered floor is simultaneously prompted.

Third mode-elevator users riding in the car and detained elevator users register their destination floors again

Prompting an elevator user who takes the car from the registered floor to register a target floor of the elevator user by using an in-car floor registration device, and obtaining the target floor of the elevator user who takes the car from the registered floor according to a registration result; at the same time, the elevator user staying at the registered floor is prompted to register the target floor again by using the target floor registration device on the landing, and the target floor of the elevator user staying at the registered floor is obtained according to the registration result.

The car floor registration device provides only destination floor registration options registered by an elevator user, which are received by a destination floor registration device at a landing of the registered floor.

Example four

In addition to the first embodiment, the present embodiment will further describe in detail a specific method of determining the destination floor of the elevator user staying at the registered floor and the destination floor of the elevator user riding in the car from the registered floor in step S6.

Specifically, the target floors of elevator users who take the car from the registered floor and the target floors of elevator users who stay at the registered floor are distinguished according to the following steps:

step B2, determining the target floor registered on the registration floor according to the identity characteristics (biological characteristics or carrying objects such as intelligent mobile terminals and cards) of the elevator user;

EXAMPLE five

In addition to the first embodiment, the present embodiment will further describe in detail how elevator users staying at a registered floor are allocated.

In step S8, an elevator is allocated to an elevator user staying at a registered floor in two ways:

mode 1, a conventional elevator group control strategy based on destination floor information is adopted to reallocate elevators for elevator users staying at the registered floor, wherein the allocated elevators are all elevators;

mode 2 is to reserve the original allocation result for the elevator user staying at the registered floor, so that the elevator user staying at the registered floor is still in charge of transportation by the original elevator in charge of transportation of the staying elevator user in the original allocation result.

In the method 1, when re-allocation is performed by using a conventional elevator group control strategy based on destination floor information, the waiting time of the elevator user staying at the registered floor includes the waiting time that has occurred before the staying occurs.

When at least one of the following conditions is established, the original distribution result is retained in the mode 2:

In addition, the original elevator adopting the original distribution result has the following three response modes for the newly added elevator taking request in the process of conveying the detained elevator users:

Mode 1, newly-added elevator taking requests are distributed to other elevators except the original elevator which is responsible for conveying the detained elevator users in the whole process from the time when the detaining occurs to the time when the original elevator finishes the conveying of the elevator users detained at the registration floor;

mode 2, the newly increased elevator taking request is only distributed to other elevators except the original elevator which is responsible for transporting the detained elevator users in the whole process from the time when the detaining occurs to the time when the original elevator finishes the transportation of the existing elevator users in the elevator car, the distributed elevator taking request service and the returning of the detained elevator users to the floor where the detained elevator users are located;

in the method 3, the newly added elevator taking request is only distributed to other elevators except the original elevator which is responsible for transporting the detained elevator users in the whole process from the time when the detaining occurs to the time when the original elevator finishes the transportation of the existing elevator users in the elevator car and the distributed elevator taking request service.

EXAMPLE six

On the basis of the first embodiment, step S7 of this embodiment further includes:

Responding to the ignored elevator taking request in any one of the following modes:

mode 1, the elevator is reallocated for the overlooked elevator taking request by adopting a conventional elevator group control strategy based on destination floor information, wherein the allocated object elevator is all elevators;

and 2, reserving the original allocation result for the ignored elevator taking request, so that the ignored elevator taking request is still responded by the original elevator in the original allocation result, which is responsible for responding to the ignored elevator taking request.

When the mode 2 responds to the neglected elevator taking request, the newly increased elevator taking request is only distributed to other elevators except the original elevator responsible for responding to the neglected elevator taking request in the whole process from the moment when the neglected elevator taking request is generated to the moment when the original elevator finishes the transportation of the elevator user generating the neglected elevator taking request.
