Description

Elevator control method

Technical Field

The invention relates to the field of elevators, in particular to an elevator control method for realizing energy saving of an elevator by properly adjusting the elevator taking time of an elevator taking request signal.

Background

The present elevator generally arrives at the passenger's departure floor within a minimum time after receiving an immediate boarding request signal from the passenger to provide service to the passenger, or waits at the departure floor before the boarding time after receiving the boarding reservation of the passenger to provide service to the passenger. In fact, in most cases, the boarding time of passengers can be adjusted slightly within a certain range, such as: the elevator is taken from home to go downstairs to go to work in the morning, and the original departure time can be properly advanced (such as advanced by 2 minutes); when going out from home and going downstairs to walk after dinner, the user can slightly adjust the original departure time (for example, 10 minutes after going forward). That is, the elevator does not need to strictly and accurately follow the passenger's designated boarding timing when providing service to the passenger, but can be slightly adjusted within a certain range. On the other hand, for two sets of elevator-taking request signals which are identical except for the elevator-taking time, there may be a great difference in the operation efficiency of the elevator when the two sets of elevator-taking request signals are responded to and passenger transportation is completed, and in the required operation time, the number of stops, the moving distance, the power consumption, and the like. Thus, for a given set of elevator taking request signals, if the elevator taking time of the elevator taking request signals is allowed to be adjusted within a certain range, the moving distance of the elevator can be shortened and the electric energy consumption of the elevator can be reduced by properly adjusting the elevator taking time of the elevator taking request signals.

Thus, how to shorten the moving distance of the elevator and reduce the power consumption of the elevator by properly adjusting the boarding timing of the boarding request signal becomes a technical problem to be solved.

Detailed Description

Other advantages and effects of the present invention will become readily apparent to those skilled in the art from the following detailed description, wherein it is shown in the accompanying drawings, wherein the specific embodiments are by way of illustration. 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

As shown in fig. 1, the elevator control method of the present embodiment includes the steps of:

s2, taking the elevator taking request signal with the elevator taking time in the time window as a selected elevator taking request signal;

s3, judging whether the selected elevator taking request signal meets special conditions according to the elevator taking time, if so, turning to the S4, and if not, finishing;

s5, controlling the elevator according to the adjusted elevator taking time so as to provide transport service for passengers;

here, the elevator taking request signals are known in advance, and the sources of the elevator taking request signals are two, one is an elevator taking reservation request signal which is pre-established by a passenger by using a mobile phone or special equipment and is informed to an elevator control system to take an elevator from a certain departure floor (or also comprises going to a certain destination floor) at a certain future time; the other is the boarding law when the passenger gets on the elevator to go out, which is obtained by analyzing the historical boarding data of the passenger or the elevator (may be the regular trip when a specific passenger gets on the elevator from a certain departure floor (or also includes going to a certain destination floor) at a certain moment, or may be the boarding request signal regularly registered at a certain moment at a certain floor of the building where the elevator is located).

The foregoing specific conditions include:

a condition B, wherein the time interval tau between the earliest elevator taking time and the latest elevator taking time of the elevator taking request signal does not exceed a time threshold gamma (gamma is less than or equal to T);

the condition C, the boarding timing of each boarding request signal is adjustable within a given range ± β (β > 0).

Here, the parameter β satisfies: 0 ≦ β ≦ Γ/2, or more preferably, satisfies: beta is more than or equal to 0 and less than or equal to gamma/2.

Step S4, the elevator taking time of the selected elevator taking request signal is adjusted according to the starting floor and the elevator taking direction of the selected elevator taking request signal or according to the starting floor and the target floor, and the sequence of the elevator responding to the selected elevator taking request signal is adjusted by adjusting the elevator taking time of the selected elevator taking request signal, so that the elevator achieves the purpose that the passenger carrying of the selected elevator taking request signal achieves the preset optimized target

The optimization objectives include at least one of shortest travel distance, minimum power consumption, minimum number of stops, shortest runtime, and highest shipping efficiency.

Example two

In this embodiment, the step S4 is further described in detail based on the first embodiment.

The special conditions further include:

and according to the condition D, the maximum passenger number obtained by merging the passengers in the same elevator taking direction according to the elevator taking routes (namely the routes between the departure floor and the destination floor) does not exceed the rated passenger capacity of the elevator.

Said step S4 achieves a predetermined optimization goal from the passenger transport of the elevator fulfilling said selected elevator taking request signal by adjusting the order in which the elevator responds to said selected elevator taking request signal such that as many of said selected elevator taking request signals as possible are fulfilled on one upward or/downward trip of the elevator.

The step S4 further comprises the following substeps:

the substep S4-2 is used for sequencing the elevator taking request signals in the uplink selected elevator taking request signal group from bottom to top according to the corresponding elevator taking starting floors and sequencing the elevator taking request signals in the downlink selected elevator taking request signal group from top to bottom according to the corresponding elevator taking starting floors;

and a substep S4-3 of respectively adjusting the elevator taking time of the elevator taking request signals in the uplink selected elevator taking request signal group and the downlink selected elevator taking request signal group, so that the sequence of the departure floors of the selected elevator taking request signals sequenced according to the time sequence at the adjusted elevator taking time is respectively consistent with the sequencing result of the substep S4-2.

And the substep S4-3 realizes the adjustment of the elevator taking time by adding a time adjustment amount on the basis of the original elevator taking time.

The substep S4-3 selects the time adjustment amount according to the following adjustment principle:

the adjusted interval between two adjacent elevator taking time points and the movement time required by the movement of the elevator between two departure floors of the corresponding elevator taking request signalThe difference α satisfies: alpha is more than 0 ₁ ≤α≤α ₂ Wherein the parameter α ₁ And alpha ₂ Are all positive real numbers.

The adjustment sets the adjustment amount corresponding to the boarding timing of one of the selected boarding request signals in the signal group to 0.

The adjustment is made by setting the adjustment amount so that the sum of absolute values of the adjustment amounts at all times is the smallest.

For ease of illustration, consider the following simple application scenario:

only one elevator with the rated passenger carrying quantity of 10 is arranged in the building, and the elevator has 10 stopping floors from 1 floor to 10 floors. The selected elevator taking request signal includes:

1) 7, the lower storied building 10,8 descends to the lower storied building 1, 1 person;

2) 7, 3 people go downwards from the 12 th floor to the 9 th floor;

3) 7, floor 09,5 goes down to floor 1, 2 persons;

4) Floor 7, floor 11, floor 10 goes down to floor 1, 2 people.

If according to the conventional elevator control method, the elevator first responds 3), 2 passengers are sent from floor 5 to floor 1; then responding to 1), returning to the 8 th floor, and sending 1 passenger from the 8 th floor to the 1 st floor; then response 4), returning to the 10 th floor, and sending 2 passengers from the 10 th floor to the 1 st floor; and finally responding to 2), returning to the 9 th floor, and sending 3 passengers from the 9 th floor to the 1 st floor. Therefore, in order to transport passengers in a return journey at the time when the passengers take the elevator, the elevator needs to go back and forth for multiple times and stop for multiple times, the required moving distance and the required transporting time are long, and the transporting efficiency is obviously low.

The elevator control method of the present embodiment can appropriately control such a situation, and significantly improve the transportation efficiency.

For the aforementioned 4 selected elevator-taking request signals, all the signals are down going. The maximum number of passengers obtained after the corresponding elevator taking routes are combined appears in a section from the 5 th floor to the 1 st floor, and the number of the passengers is 9, so that the condition D is obviously met.

Considering that the building has 10 floors in total, the movement time required for the elevator to move from floor 10 to floor 9, from floor 9 to floor 8, and from floor 8 to floor 5 is very short, and therefore the movement time is ignored when adjusting the boarding timing.

In order to achieve the optimization goal, the elevator is allowed to finish the transportation of all passengers from the top to the next time, and the elevator taking time is directly and identically adjusted to the same elevator taking time, such as: 7, by informing all passengers to arrive at the elevator lobby before the moment and to board the elevator. The elevator will wait at floor 10 and be ready to go down no later than 7 c at 10 c (of course, even if both the elevator and the 10-floor passenger arrive 10 a lobby in advance, the elevator will not start earlier than 7 c.

Note: due to the simple application scene, the example elevator-taking time adjustment process is not carefully explained, and the elevator-taking time adjustment process needs to be supplemented if necessary.

EXAMPLE III

In the second embodiment, only the processing when the condition D is satisfied is considered, and in the present embodiment, the processing when the selected boarding request signal does not satisfy the condition D is considered.

When the condition D is not satisfied, any corresponding mode is adopted:

In the mode 2, the grouping processing follows at least one of the following grouping principles:

grouping principle 1, minimum group number;

grouping principle 2, the span range of the taking time of the taking request signal in the group is minimum.

Grouping operation is carried out according to the following steps:

When only the grouping principle 1 is adopted, the grouping operation is carried out according to the following steps:

and step B4, selecting the grouping result suitable for each special elevator riding distance from all the grouping results, and taking the grouping result with the minimum group number as a final grouping result and outputting the final grouping result.

Example four

This embodiment further describes step S4 in detail based on the first embodiment.

And the step S4 is used for adjusting the order of the elevators responding to the selected elevator taking request signals, so that the elevators respond to the floor distance between the first-out floor and the farthest destination floor in the uplink selected elevator taking request signal group and the downlink selected elevator taking request signal group in a priority mode.

The step S4 further comprises the following substeps:

substep S4-3, calculating respective distances for the uplink selected elevator taking request signal group and the downlink selected elevator taking request signal group, respectively;

and a substep S4-5 of adjusting the boarding moment of the selected boarding request signal in the set of priority response signals and/or the set of non-priority response signals so that the elevator will respond preferentially to the selected boarding request signal in the set of priority response signals.

Said sub-step S4-5 estimates the transportation time required for the elevator to complete the passenger transportation of the boarding request signal in said priority response signal group and then adjusts so that the boarding time of the earliest responded boarding request signal in the non-priority response signal group is later than the time at which the elevator completes the passenger transportation of the boarding request signal in said priority response signal group.

The present embodiment mainly deals with the situation when the selected elevator taking request signal includes both the upward elevator taking request signal and the downward elevator taking request signal. The core idea is as follows: the ascending and descending elevator taking times are decoupled by adjusting the elevator taking times, and then the method in the embodiment can be adopted to respectively process the ascending elevator taking request signal and the descending elevator taking request signal.

The present invention has been described in detail with reference to the specific embodiments, which are merely 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.
