Abstract
An elevator system includes elevator cars connected to a controller having a channeling program which controls car dispatching during up-peak. The channeling program automatically or dynamically adjusts or changes the number of cars controlled by the channeling program, dependent upon various service parameters such as Lobby Arrival Interval, Average Waiting Time, Overall Service Time or Hall Call Registration Time.
Description
Technical field
The present invention relates to the scheduling of elevator, particularly relate to a kind of channel allocation of using during the up peak phase, wherein pinao nobile or the marshalling of the building floor segmentation more than the hall, each section comprises one group of continuous floor, and is that each section is distributed a car.
Prior art
During the up peak phase, if there is the car of two part cargo shipments to leave the hall in the predetermined time cycle, the elevator dispatching system will call out all cars as usual again and get back to the hall, so that handle the passenger flow volume that enters from the hall.Start known channel operation like this.
In a kind of known channel allocation operating period, controller or operation control subsystem (OCSS) is divided into several sections to the building.The quantity that this hop count equals to move car subtracts 1; So just stayed a vacant car.The scope of each section comprises the service floor of equal number.
The US Patent 4 that people such as Bittar authorized on December 20th, 1988,792, No. 019, promptly in " Contiguous Floor Channeling With Up Hall CallElevator Dispatching " a kind of representative type channel allotment program has been proposed, for example herein shown in Fig. 2 A-2C, Fig. 2 A-2C in the corresponding US Patent of these figure ' 019.The lift car 1-4 that returns to Chinese Taiwan as the part of elevator group control system is a building service, and there are a plurality of floors in the building, for example has 12 layers at pinao nobile or more than the hall.Referring to Fig. 1, Fig. 1 of this figure correspondence ' No. 019 patent, but a following only repeat specification part wherein is used to explain operating environment of the present invention.Each self-contained cage operating panel 12 of car 1-4 sends out car call toward a floor thereby the passenger can press button on it, produces a signal (CC) of discerning passenger's whereabouts floor.An entrance hall equipment 14 is arranged on each floor, and the passenger on this floor produces the hall call signal (HC) of an indication service direction by it.Another hall call equipment 16 has been located in hall (L), and the passenger calls out the sedan-chair Room by it and gets back to the hall.Situation about describing among Fig. 1 is, to the selection of car, at this moment the floor 2-13 more than the pinao nobile has been divided into three sections (SN) during the up peak phase, and every section comprises four floors.In the time in office, have only one of four car 1-4 in service in each continuous section.With reference to the diagram of circuit of Fig. 2 A-2C more detailed explanation has been made in this channel allocation operation, all the other can be referring to as No. the 4th, 792,019, the US Patent of the application's bibliography.As shown in Figure 1, a car is idle as car 1.Each car 1-4 only respond in car, send from the hall go to the section of distributing to this car the car call of several layers of floor that conforms to.For example car 4 only responds the car call of going to floor 10-13 from the hall.Some other known access to elevators allocation scheme also, for example US Patent the 4th, 804, No. 069; 4,846, No. 311 and 5,183, No. 981, these all are the bibliographys of this paper.
In channel allocation operating period, the passenger flow of intermediate floor appears through regular meeting.The intermediate floor passenger flow for example is the above normal passenger flow between the layer of continuing in hall.In the prior art, descending hall call is to utilize known relative system response (RSR) program of separating with channel allotment program to be handled by the car that moves on the down direction.For example US Patent the 4th, 363, and 381 and 4,323, the RSR program described in 142, these files also are the bibliographys of this paper.Utilize known RSR program, the up Room is called out by the car for that section service of sending hall call and is replied.Yet the car of serving top, building 2/3 all can be assigned with replys these entrance halls and exhales.Therefore, the passenger who goes to upper sector from the hall can feel that the performance of elevator device has descended, and this is because will stop once at least in order to respond hall call, and also will stop once more probably, so that the car call that the passenger that response enters from the hall sends.
Whether therefore, for the very heavy building of intermediate floor passenger flow volume, if adopt known channel allotment program, no matter combine with known RSR program, the passenger who goes to upper sector from the hall can feel the elevator device performance decrease during the up peak phase.In addition, this situation can increase the round time of run that returns the hall, and just arrival interval, hall (LAI), this leaves the hall to the time of returning the hall from car during being meant the up peak phase at interval.The inventor thinks and can realize further improving to channel operation.

In Fig. 1, as the part in the elevator group control system.Four lift car 1-4 are arranged for having the building service of a plurality of (for example 13) floor.Each car 1-4 comprises a cage operating panel 12, sends out toward the bridge railway carriage or compartment of a floor and calls out thereby the passenger can press button on it, produces a signal CC who discerns passenger's whereabouts floor.An entrance hall equipment 14 is arranged on each continues layer, and the passenger on this floor produces the hall call signal HC of an indication service direction by it.L place, hall is provided with a hall call equipment 16, and the passenger calls out car by it and gets back to the hall.In Fig. 1, the above floor 2-13 in pinao nobile or hall is divided into three sections, and every section comprises four floors.In the time in office, have only in continuous every section one of four car 1-4 to be its service.A kind of channel allotment program of prior art has been described in Fig. 2 A-2C, N=hop count wherein, NC=car sum, SN is a segment number, and CN is a car number.Each car 1-4 repercussion should in car, send from the hall go to the section of distributing to this car a car call of sending out the floor that layer conforms to.For example car 4 only responds the car call of going to floor 10-13 from the hall.Car can be carried to these floors (10-13) to the passenger from the hall, (so long as the car call of going to these floors is arranged), sky is sailed and is got back to the hall then, only uses other scheduler programs to distribute this car to remove to reply upstream or downstream hall call on a certain floor.Enterable other scheduler programs are exemplified below under up peak phase (channel allocation) state: the US Patent 4 of Bittar " Relative System Response CallAssignments " by name, 363, the US Patent 4 of No. 381 and Bittar " Dynamically Reevaluateo Elevator Car Call Assignments " by name, 323, No. 142, the full text of these files can be used as the bibliography of this paper.
In Fig. 1, each car 1-4 is connected to and drives and operation controller 30.Each operation controller 30 is connected to a group control device 32.The structure of having described to use another kind of elevator device of the present invention in No. 5,202,540, the US Patent of Two-Way RingCommunication System For Elevator Goroup Control by name (Fig. 3) can supply this paper reference.Although do not illustrate among the figure, described in above-mentioned patent of authorizing Bittar, the position of each car in the building is by controller not providing by the position indication.Controller 30,32 contains CPU (central processing unit or signal processor), is used to execute instruction and/or handles data from system.Group control device 32 uses the signal of self-driven and operation controller 30, sets the section by each car service.Each operation controller 30 receives HC and CC signal, and SI provides drive signal to service indicator.Each operation controller also receives the data from car, control car load signal LW.It also will be measured the elapsed time (being commonly referred to " wait time ") of opening the door at the place, hall.Represented driving and operation controller in very simple mode in this article, this is to have described the driving that is used for elevator and the details of operation controller in many patents and the technical press fully because have.
Therefore, can make it carry out program described herein to the programming of the CPU in the controller 30,32, thereby realize the scheduling operation mode of Fig. 2 A-2C, and one day sometime or under fixing building condition, carry out the alter mode shown in Figure 3 that the present invention proposes.And the supposition controller can take different scheduling degree at other times, for example adopts the program described in the patent of above-mentioned Bittar.This system can collect the data of whole day according to the requirement of independent and team control, thereby obtain the passenger flow volume demand history record (for example LAI or the like) of every day in the week, and it is compared with actual demand, be used to regulate the single-piece dispatching sequence, thereby obtain the desired indicator of system and cage operation performance independently.By following processing mode, but also to the big passenger flow volume of car load be analyzed by signal LW from the reflection car load of each car.Also can use the human body sensor (not shown) that is located at the hall to detect actual passenger flow volume.Be awarded two US Patent of Otis Eleiator Company, be the US Patent 4 of name such as Donofrio for " Elevator Cab Load MeasuringSystem ", 330, the US Patent 4 of No. 836 and Mottier " People andObject Counting System " by name, the scheme that can be used for producing sort signal has been described in 303, No. 8521.Adopt this data, and with the time in itself and one day, every day in one week, and the car call and the hall call of actual input interrelate, just can obtain significant statistics, during the whole up peak phase, use the signal conditioning of being implemented by the described flow sequence of Fig. 2 A-2C to come segmentation, thereby make the wait time in hall reduce to minimum.
According to the present invention (Fig. 3), as shown in the program of Fig. 3, the number of elevator of distributing to channel allotment program dynamically changes according to program.As a result, the quantity of the car B that floats also changes, and therefore, A+B=C, C wherein are the lift car sums of the service of dropping into.Usually, whole cars of group control system all can drop into service.The program of Fig. 3 can be used to the step S3 (Fig. 2 A) in the channel allotment program of alternative such as prior art; In this case, can optimally save step S29 and S30 (Fig. 2 C).Like this, the unsteady car number of intermediate floor (or the additional floor of even number) passenger flow volume can dynamically be regulated rather than fixing owing to be used to handle, and the elevator integrity service performance in the channel allocation cycle can be further improved.The program of Fig. 3 can be encoded and store (combining with the appropriate step among Fig. 2 A-2C) in the memory device M of controller 32, or deposits the memory device of OCSS (referring to ' No. 540 patents) in.
In Fig. 3, to be identified for handling all cars that enter passenger flow volume according to arrangement of the present invention and count A, and will be identified for handling the remainder B of the car of intermediate floor (or the additional floor of even number) passenger flow volume.A+B=C, C wherein are the car sums (for example being 4) of the service of dropping into.According to the present invention, car under channel allotment program control is counted A and is depended on such as arrival interval, hall or integrity service time, or average latency (AWT), or any required combination of these factors that record in " I " time gap in the past.I can be selected by the supvr in building or programme voluntarily, for example be decided to be 5,10,15 minutes or any other required time at interval.Unsteady car dispatching is controlled by other (being non-channel allocation) scheduling degree, for example Bittar ' 381 or ' program described in No. 142 patents.
If LAI or AWI or integrity service time are greater than a certain upper limit (can select or able to programme), the solution of the present invention can automatically increase the car of distributing to channel allocation and count A, and automatically reduce and distribute to unsteady car and count B, be i.e. A=A+1, B=B-1.The condition of the limit is A=C and B=0, thereby makes A+B=C.The car of distributing to channel allocation is counted the scope that the increase of A can the section of making and is dwindled, and can improve the service at place, hall.
If LAI or AWT are less than or equal to the upper limit, and, just increase by 1, so that handle intermediate floor (or the additional floor of the even number) passenger flow volume that increases A minimizing 1 and B more than or equal to a certain lower limit.B is a quantity of distributing to the car that floats.The limiting conditions of this moment are A=0 and B=C, thereby make A+B=C.This is brightly can regulate the passenger flow volume that enters during the up peak phase, also can handle the passenger flow volume of heavy intermediate floor (or the additional floor of even number) simultaneously.
In the program of Fig. 3, at first read arrival interval, hall (step 100), set C=A+B, the step 110.If LAI is not less than or equals for example is 60 seconds the upper limit, just go on foot 125 from going on foot 120.In the step 125,,, just set A=A+1 and set B=B+1 if A is not equal to C if A=C just sets A=C.Withdraw from then.If LAI is less than or equal to the upper limit, just go on foot 130.In the step 130,, just enter the step 135 if LAI is not greater than or equal to a lower limit (for example 20 seconds).In the step 135, if A=0 just sets A=0; If A is not equal to 0, just set A=A-1.If B=C just sets B=C; If B is not equal to C, just make B=B+1.
According to the solution of the present invention that comprises program shown in Figure 3, distribute to the unsteered lift car number of channel allocation and change according to upper and lower limit with the car number that floats.Certainly, except LAI, average latency or integrity service time with and any combination also can by be used as the step in 120,130 measurement or read criterion.
Fig. 4 shows an additional embodiment of the present invention.Wherein up hall call enrollment time (UHC) is determined criterion as one, rather than adopt LAI, AWT or integrity service time.UHC enrollment time is meant from up hall call time registered and begins time cycle of finishing when a car is replied this calling.The hall is left until the time that arrives between the hall from car during being meant the up peak phase in arrival interval, hall (LAI).Average latency was meant from passenger's in-track platform (being the hall) up to passenger's cycle between the ladder from the platform.The integrity service time is to arrive the cycle that begins in the building up to the passenger finishes from the passenger when the destination platform is walked out car.Average enrollment time is meant the cycle platform begins to open from passenger's in-track platform to car door.The definition of intermediate floor and additional floor passenger flow volume can be referring to U.S. Patent application ' No. 019, or a middle thread layer passenger flow volume is decided to be: the normal passenger flow volume of the above floor gap in intermediate floor passenger flow volume=hall.
Although more than be with accompanying drawing and text description most preferred embodiment of the present invention, those skilled in the art obviously can also make various changes and modification under the condition that does not break away from notion of the present invention and scope, the present invention only is subjected to the restriction of accessory claim.
