The control method of the elevator according to claim 1 or 2, characterized in that the elevator uses a mechanical linkage, the two sides under the cage door (8) pass through the pallet means (30), the pallet means (30) is composed of a supporting hook (21), a torsion spring (22) and a second positioning plate (23), the landing door (25) is provided with a stop (24); when the suspension cage door (8) rises, the supporting plate device (30) automatically pops up to bring the landing door (25) to rise simultaneously; the lifting cage door (8) and the landing door (25) are opened simultaneously, when the lifting cage door (8) descends, the second positioning plate (23) automatically recovers the jacking block, and the landing door (25) is closed simultaneously;
the specific working process is as follows:
1) electric door control system: firstly, a right-angle hollow speed reducer (19) is controlled by a PLC to drive a lifting shaft (18) to rotate, then the lifting shaft (18) drives chain wheels (16) at two ends of the lifting shaft to rotate, so that a chain (7) on the chain wheel (16) moves along with the lifting shaft, a cage door (8) and a balance weight (9) are driven to synchronously move, and a jacking block device on the cage door (8) automatically pops up through a torsion spring to drive a landing door (25) to move up and down; when the suspension cage door (8) stops at the base layer, the coil of the door entrance contactor is electrified; the PLC drives the frequency converter, the door inlet contactor and the motor 2 to form a main circuit, the door inlet of the suspension cage door (8) is automatically opened and automatically stopped when colliding with the door opening limit, the door inlet of the suspension cage door (8) is automatically closed when reaching the set time, and the door inlet of the suspension cage door automatically stops when colliding with the door closing limit; when the suspension cage door (8) stops at other target floors, the contactor coil of the landing door (25) is electrified; the PLC driving frequency converter, the door inlet contactor and the motor 1 form a main circuit, the cage lifting door (8) drives the landing door (25) to be automatically opened, and the landing door automatically stops when colliding with the door opening limit; after stopping for a period of time, the cage door (8) drives the landing door (25) to automatically close, and the landing door automatically stops when colliding with a door closing limit; when the door of the suspension cage door (8) is opened or closed and the limit switch is invalid, PLC software is programmed to carry out time protection;
2) the intelligent driving and controlling system controls a double-cage linkage mode by an outbound button in the using process:
(2-1) when the double cages are static, the cage (5) of the nearest landing is used for priority;
(2-2) the direction of the operation suspension cage (5) is the same, and the operation suspension cage (5) takes precedence; in the opposite direction of the operation cage (5), the target floor of the operation cage (5) is higher than the outbound floor, and the static cage (5) takes precedence; the target floor of the operation cage (5) is lower than the outbound floor, and the operation cage (5) takes precedence;
(2-3) double-cage operation, wherein the cage (5) is operated in the same direction preferentially; in the opposite direction of the operation cage (5), the operation cage (5) of the nearest target floor is prioritized;
(2-4) the rules (2-1), (2-2) and (2-3) are met, when the cage (5) which should respond has a fault, including if the cage (5) is opened, the fault is automatically recovered by the non-fault cage (5) preferentially; if the recovery is not carried out within the time limit, the fault-free cage (5) responds; non-automatic recovery failure, responded by the non-failure cage (5).
