Description
Technical Field
The invention mainly relates to the technical field of elevators, in particular to a dynamic zone control method for an elevator group.
Background
At present, high-rise buildings with comprehensive services are gradually increased, the comprehensive services are office services, hotel services, apartment services, commercial services and the like in one high-rise building, however, the current single-part and parallel operation mode cannot meet the passenger flow of the high-rise building and the high requirement of people on the elevator operation efficiency, so the research of the elevator partition method is carried out on multi-target parameters of an elevator group control system: the passenger's waiting time, riding time and energy consumption have profound significance.
The introduction of PLC in elevator industry greatly increases the stability and anti-interference performance of elevator operation, and because the function of PLC controller is gradually strengthened, its input and output capability and number, communication, numerical calculation, program design, etc. are all greatly improved, the realization possibility of algorithm is increased, and the system design is more flexible.
Static partitioning method: the method is characterized in that the overall area of the vertical floor of the building is divided into fixed sub-areas, and a certain elevator is allocated to fixedly serve a certain sub-area. The high-rise building of the comprehensive service has the functions of offices, hotels, apartments, businesses and the like. The existing elevator group with static partitions the areas according to the functional characteristics of the building floors and then sets the number of elevators served by the area in advance according to the prediction of the passenger flow of different areas. However, the method does not consider the time-varying characteristic of the passenger flow between zones, so that the number of the elevators is unevenly distributed, the task load of the elevator in the zone with large passenger flow is heavy, and the task load of the elevator in the zone with small passenger flow is low, so that the elevator resource allocation is uneven, the running efficiency is low, and the energy consumption is high.
The dynamic partitioning method comprises the following steps: the dynamic partition method is an improvement of the static partition method, generates new partitions according to a preset rule, and dynamically allocates the partitions to each elevator. Because the dynamic partitioning considers the time-varying characteristics of passenger flow and space, although theoretically, the dynamic partitioning has better dynamic performance than the static partitioning, the change of the partitioning is to seek uniform partitioning, mainly reflects the balance of single-elevator task load, and sometimes can be used for multiple target parameters: the passenger waiting time, the taking time and the energy consumption cause bad influence.

The invention will be described in further detail below with reference to the drawings and specific examples.
Fig. 1 to 3 show an embodiment of the elevator group dynamic zone control method of the present invention, in which a building is provided with a waiting zone 2 around an elevator group 1 and is further provided with an external call registration port 3, the elevator group 1 includes a plurality of hoistways 5 and self-driven cars 4 whose number is greater than that of the hoistways 5, each car 4 is disposed in a corresponding hoistway 5, and each car 4 can perform track-changing operation in a single hoistway 5 and in each hoistway 5, specifically including the following steps:
s1: the external call registration port 3 records the destination layer of each passenger;
s2: counting all destination floor numbers and the number of people at each destination floor;
s3: matching the elevator cars 4 in the subareas according to the total span of the target floor, and matching the number of the elevator cars 4 according to the number of people in each subarea;
s4: each car 4 arrives at the lobby area 2 to receive passengers of the corresponding zone floor according to the zone matching result of step S3;
s5: each car 4 travels to the matching destination floor.
The invention records the destination floor of each passenger in real time through an external call registration port 3, counts all destination floor numbers and the number of people of each destination floor, matches the subarea elevator cars 4 through the group controller according to the total span of the destination floor, matches the number of the elevator cars 4 through the group controller according to the number of people of each zone, aims at the buildings with dense people flow, particularly the peak time of working, obtains the optimal ratio of the subarea elevator cars 4 matched with the total span and the elevator cars 4 matched with the number of people of each zone through the dynamic statistics of the destination zone floor, realizes the function of dynamic subarea, reduces the stopping times of the elevator through the mode of conveying the centralized zone floor, improves the whole carrying efficiency, can be applied to the traditional elevator and the multi-elevator cars 4, particularly the multi-elevator cars 4, reduces the running stroke of the single elevator car 4 and the stopping times, and can also reduce the rail change avoiding times of the elevator caused by the stopping of the elevator in front, the overall smoothness of the multi-car 4 in the hoistway is improved.
