Abstract
The invention provides an elevator pre-starting control method, which comprises the following steps: the passenger finishes the floor registration, and the elevator executes the door closing action; in the door closing process, detecting and judging whether the elevator meets a pre-starting condition, and if so, enabling the operating contactor to be closed; the suction feedback of the running contactor is made to the elevator system, and the elevator car is at zero speed; and opening the band-type brake, making band-type brake opening feedback to the elevator system, and accelerating the lift car. The pre-starting conditions include: the car is in the openable door area, and the current running speed is lower than a preset speed value. Under the condition of ensuring safety, after the passenger registers the floor information, a series of action time sequences are completed in advance in the door closing process of the lift car, thereby realizing pre-starting, improving the running efficiency of the lift and reducing the waiting time of the passenger.

Technical Field
The invention belongs to the technical field of elevators, and particularly relates to an elevator pre-starting control method.
Background
At present, the sequence of a series of actions of closing a door and conveying a passenger to a destination floor after an elevator receives passenger registration information is as follows: registration-safety loop connection-door closing in-place feedback-operation contactor actuation feedback-elevator zero speed-brake opening feedback-elevator acceleration. The time from registration to the beginning of the elevator operation is about 1-2 seconds, which is not in accordance with the requirement of high efficiency.
Disclosure of Invention
In order to overcome the problems in the prior art, the invention provides an elevator pre-starting control method, aiming at improving the operation efficiency of an elevator and saving the waiting time for passengers to take the elevator; the specific technical content is as follows:
an elevator pre-starting control method comprises the following steps:
s01, the passenger completes the floor registration, and the elevator executes the door closing action;
s02, detecting and judging whether the elevator meets the pre-starting condition or not in the door closing process; when the pre-starting condition is met, the elevator is started.
Further, step S02 includes the following sub-steps:
s021, detecting and judging whether the elevator meets a pre-starting condition, and enabling the running contactor to be closed if the elevator meets the pre-starting condition;
s022, performing suction feedback of a running contactor to an elevator system, and enabling the elevator car to be at zero speed;
s023, opening a band-type brake, making feedback of opening the band-type brake to an elevator system, and accelerating the car.
In one or more embodiments of the present invention, the pre-boot condition includes: the car is in the openable door area, and the current running speed is lower than a preset speed value. The preset speed value is preferably 0.3 m/s.
In one or more embodiments of the present invention, the elevator system is connected to and obtains the states of the landing switch and the door zone switch to determine whether the car is in the openable door zone.
In one or more embodiments of the invention, the door-to-position switch is connected in series with the operating contactor; a bypass connected with the in-place switch in parallel is arranged, the bypass is controlled by a safety relay to realize on/off control, and the safety relay is controlled by an elevator system; when the pre-starting condition is met, the elevator system conducts the safety relay to enable the operation contactor to be attracted, and then the car is started.
In one or more embodiments of the invention, the door-to-location switches include a gate-to-location switch and a hall-to-location switch connected in series.
The invention has the beneficial effects that: under the condition of ensuring safety, after the passengers register floor information, a series of action time sequences are completed in advance in the door closing process of the lift car, pre-starting is realized, the operation efficiency of the elevator is improved, and the waiting time of the passengers is reduced. Specifically, by additionally arranging a bypass on a circuit of the operation contactor, when the elevator meets certain conditions (if a car is in an openable door area and the operation speed is less than 0.3 m/s), the hall door in-place switch and the car door in-place switch are bypassed, and the operation contactor is directly conducted to realize the advance acceleration of the elevator when the doors are not closed in place.

FIG. 2 is a flow chart of the pre-start control of the present invention.
Detailed Description
The scheme of the present application is further described below with reference to figures 1 and 2:
an elevator pre-starting control method adopts an elevator wiring structure as follows:
the door-in-place switch is connected with the operation contactor KM in series and is provided with a bypass connected with the door-in-place switch in parallel, the bypass is controlled to be switched on/off by a safety relay K4, and the safety relay K4 is controlled by an elevator system; the door-in-place switch comprises a sedan door-in-place switch K2 and a hall door-in-place switch K3 which are connected in series.
Which comprises the following steps:
after the passenger finishes the floor registration, the safety switch K1 is closed, and the elevator performs the door closing action;
in the door closing process, whether the elevator meets a pre-starting condition is detected and judged, wherein the pre-starting condition comprises the following steps: the car is in an openable door area, and the current running speed is lower than 0.3 m/s; the elevator system is connected with and acquires states of a leveling switch and a door area switch so as to judge whether the car is in the openable door area;
if the safety relay K4 is met, the elevator system conducts the safety relay K4, and the car door in-place switch K2 and the hall door in-place switch K3 are bypassed, so that the running contactor KM is attracted;
after the operation contactor KM is attracted, attraction feedback of the operation contactor KM is made to the elevator system, and the elevator car is at zero speed;
the contracting brake KBR is opened, and contracting brake opening feedback is given to an elevator system, so that the car is accelerated in advance when the car is not closed, the running efficiency of the elevator is improved, and the waiting time for passengers to take the elevator is saved.
The above preferred embodiments should be considered as examples of the embodiments of the present application, and technical deductions, substitutions, improvements and the like similar to, similar to or based on the embodiments of the present application should be considered as the protection scope of the present patent.
