Description

Technical Field

[0001] The invention relates to the technical field of elevators, and in particular to an intelligent control system of a construction elevator for both people and goods. Background Art

[0002] Construction elevators are also called construction elevators for buildings, outdoor elevators, and construction site hoist cages. They are manned and cargo-carrying construction machinery that is often used in construction. They are mainly used for the interior and exterior decoration of high-rise buildings, bridges, chimneys and other construction projects. Due to its unique box structure, construction workers can ride comfortably and safely. Construction elevators are usually used in conjunction with tower cranes on construction sites. The general construction elevator has a load capacity of 1-10 tons and a running speed of 1-60m / min.

[0003] (1) The mainstream construction elevators for both passenger and cargo use a handle (master switch) operation mode. The professional driver controls the elevator to go up / down by the control handle. The elevator needs to be repeatedly operated to accurately level the floor, which is complicated to operate and easy to cause fatigue to the personnel.

[0004] (2) Dual-purpose construction hoists for people and cargo are usually operated in a double-cage mode, with two dedicated drivers controlling the left and right cages respectively. The double cages operate independently, which easily leads to a situation where one cage is busy while the other is idle. The double cages cannot be reasonably scheduled for operation, resulting in low transportation efficiency.

[0005] (3) There is no effective protection measure for the floor door, which completely relies on the elevator driver or on-site workers to consciously close the floor door. If the floor door is not closed properly, the elevator can still operate normally, which poses a great safety hazard;

[0006] (4) The common inlet and outlet doors of the elevator are opened and closed manually, which has low working efficiency. Under manual operation, the service life of the inlet and outlet doors will be reduced;

[0007] (5) The left and right cage operating status displays are not configured at the door locations on each floor. On-site workers cannot understand the operating status of the double cages on the floor. If a malfunction occurs and the elevator cannot operate, it may cause on-site workers to wait blindly, affecting work progress. Summary of the invention

[0008] The purpose of the present invention is to provide an intelligent control system for a construction elevator for both passengers and cargo, so as to solve the problems raised in the above-mentioned background technology.

[0009] To achieve the above object, the present invention provides the following technical solutions:

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1-Figure 5 In an embodiment of the present invention, an intelligent control system for a construction elevator for both passenger and cargo use includes an external call part, a left cage part, and a right cage part;

[0039] The hall call part includes the hall call box on the first floor and the hall call boxes on the remaining floors;

[0040] The first-floor hall call box consists of a hall call control panel, a touch screen human-machine interface, the first LoRa wireless module, an LCD / digital tube display panel, and two sets of up / down buttons. It is externally connected to the left and right cage door limits, and communicates with the upper-floor hall call box through the CAN bus communication circuit on the hall call control panel; the first LoRa wireless module is placed in the first-floor hall call box, and the first LoRa wireless module communicates with the left and right cages to obtain the operating status information of the left and right cages, and automatically allocates the collected up / down button signals to the left and right cages according to the single-cage independent control or double-cage scheduling control logic to operate the floors.

[0041] The hall call boxes on the other floors are composed of a hall call control panel, an LCD / digital tube display panel, and two sets of up / down buttons. They are connected to floor door limit or floor door electromagnetic lock, and communicate with the hall call box on the upper floor through the CAN bus communication circuit on the hall call control panel. The floor door limit or floor door electromagnetic lock is used to realize the electromechanical interlocking function of the floor door.

[0042] The first floor exterior call box serves as the CAN bus communication host, and is used to receive the up / down button signals, outer cage door limit and floor door limit signals reported by all exterior call boxes; the exterior call boxes on the other floors serve as CAN bus communication slaves, and are responsible for receiving the left and right cage operation status information sent by the host; the first floor exterior call box and the exterior call boxes on the other floors are connected via CAN bus communication, and are used to report the up / down button signals and floor door limit signals to the communication host; when the floor door electromagnetic lock is equipped, when the cage stops at the corresponding exterior call box floor and meets the door opening conditions, the floor door electromagnetic lock is driven to close;

[0043] The external call box uses two sets of up / down buttons to realize the logic of single cage independent control or double cage dispatch control: when a single cage is controlled independently, the up / down button on the left side of the external call box is assigned to one cage, and the up / down button on the right side is assigned to the other cage; when a double cage is dispatched and controlled, the two up buttons of the external call box have the same function, and the two down buttons have the same function. After the first-floor external call box collects the up / down button signals of the external call boxes on all floors, they are intelligently assigned to the left and right cages according to the logic of forward priority and full load straight driving.

[0044] The first floor outside call box is connected with the left and right cage outer door limits, and the other floor outside call boxes are connected with the floor door limits or the floor door electromagnetic locks to realize the electromechanical interlocking function of the floor doors; when the outer cage door or any floor door limit is disconnected, the corresponding elevator is prohibited from running.

[0045] If the elevator is not parked at the floor where the hall call box is located, the electromagnetic lock will not work, the lock tongue will extend and jam the handle, and the floor door cannot be opened at this time. When the elevator is parked at the floor corresponding to the hall call box and the door opening conditions are met, the hall call box controls the electromagnetic lock to close and the lock tongue will automatically retract. At this time, the worker can control the floor door to open through the handle; after the floor door is closed, the permanent magnet and the magnetic proximity switch are close, and the hall call box detects that the floor door of that floor has been closed normally. If the floor door is not closed normally, the permanent magnet and the magnetic proximity switch are far away, and the hall call box cannot detect the normal closing signal of the floor door, and sends the signal that the floor door is not closed well to the hall call box on the first floor through CAN bus communication. The hall call box on the first floor sends the prohibition operation signal to the corresponding elevator through the LoRa wireless module to ensure that the elevator cannot run, thereby realizing the electromechanical interlocking function of the floor door;

[0046] The left cage part includes a door machine control box, an intelligent control box, a variable frequency drive integrated machine, an Internet of Things terminal, a number recognition camera and other protection sensors; the intelligent control box is composed of an intelligent control panel, a touch screen human-machine interface, a second LoRa wireless module, a number recognition camera and other protection sensors, a keypad, floor buttons and function buttons. The intelligent control box communicates with the first floor hall call box through the second LoRa wireless module to transmit the operating status data to the first floor hall call box and receive the operating target floor assigned by the first floor hall call box;

[0047] The door machine control box is composed of a door machine control panel and a door machine frequency converter. The door machine control panel is connected to the inlet and outlet door motors through cables, and the inlet and outlet doors are automatically opened and closed by the door machine frequency converter and the relay on the door machine control panel.

[0048] The variable frequency drive integrated machine is connected to the main drive motor through a cable, and is used to transmit the target floor to the variable frequency drive integrated machine through 485 communication after the intelligent control box receives the target floor assigned by the first floor hall call box. After receiving the target floor, the variable frequency drive integrated machine controls the main drive motor to automatically level the floor and reach the floor leveling position;

[0049] The main drive motor, the feed door motor and the discharge door motor are all equipped with brake devices.

[0050] The right cage part and the left cage part adopt the same solution, and the left / right cage is distinguished by software function setting.

[0051] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Although this specification is described in accordance with the implementation modes, not every implementation mode includes only one technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
