Description

Technical Field

[0001] This invention relates to the field of construction elevators, and in particular to a digital intelligent management system for construction elevators. Background Technology

[0002] During the construction of high-rise buildings, multiple construction elevators are usually configured to meet the vertical transportation needs. However, existing construction elevators generally lack scheduling systems and rely more on the operator's judgment and rough manual scheduling. This seriously affects their efficiency, wastes resources, and increases costs.

[0003] Patent CN104709785B discloses an intelligent group control scheduling and safety control system, including a crane control system for collecting operating parameters of the elevator cage and sending them to the dispatch center, and receiving dispatch commands from the dispatch center to control the elevator cage; a floor call system for inputting floor request information and displaying dispatch-related information; a rotary track changing control system for collecting operating parameters of the rotary track changing device and sending them to the dispatch center, and receiving commands from the dispatch center to control the rotary track changing device to drive the elevator cage to rotate and change tracks; and a dispatch center for receiving floor request information or user input information, and issuing elevator cage dispatch commands based on the collected operating parameters. By adopting the scheduling system and method of this invention, comprehensive scheduling of single-tower multi-cage cyclic operation construction elevators is realized, fully utilizing the efficiency of single-tower multi-cage cyclic operation construction elevators, while improving their reliability and ensuring their safety.

[0004] However, the model it adopts is based on actual user scheduling data on site, rather than physical ride data. Its scheduling is based on human demand rather than objective environment, which makes it difficult to guarantee its operational efficiency and is greatly affected by non-objective factors, resulting in poor stability.

[0005] Therefore, a construction elevator management system that requires no human intervention throughout the entire process is needed to solve the above problems. Summary of the Invention

[0006] This invention addresses the problem that existing technologies rely on on-site user scheduling data rather than physical passenger data. The scheduling is based on human demand rather than objective environmental factors, leading to inconsistent operational efficiency, susceptibility to non-objective influences, and poor stability. This invention provides a digital intelligent management system for construction elevators that allocates transport capacity based on objective data throughout the entire process, reducing human intervention and solving the aforementioned problems.

[0007] This invention provides a digital intelligent management system for construction elevators, including a construction elevator body, an elevator-end sensor group, a lifting mechanism, and a remote manager. The construction elevator body is located inside and outside the building and moves vertically. The lifting mechanism is located at the top of the building, and its output end is connected to the construction elevator body. The remote manager controls the movement of the lifting mechanism. The elevator-end sensor group is a position sensor with a timestamp. The elevator-end sensor group is connected to the remote manager via a signal connection. The elevator-end sensor group is fixed on the car of the construction elevator body.

[0008] The remote manager includes an elevator status simulation module, a timetable module, a real-time position module for the construction elevator in the upward direction, a real-time position module for the construction elevator in the downward direction, a construction elevator operation count control module, and a monitoring module. The real-time position modules for the construction elevator in the upward direction, the real-time position modules for the construction elevator in the downward direction, and the monitoring module transmit data to the elevator status simulation module. The timetable module and the construction elevator operation count control module receive the data output by the elevator status simulation module and control the lifting mechanism.

[0009] The real-time location modules for the upward and downward construction elevators are used to collect the real-time floor coordinates of the construction elevators in the upward and downward directions, respectively. The monitoring module is used to collect the number of personnel entering and exiting the construction elevators and the construction materials accompanying them. The construction elevator operation count control module sequentially calls the construction elevator first-floor travel timetable model, construction elevator operation count model, and simulation model of the elevator status simulation module to obtain the construction elevator operation count that best meets the constraints of the project construction. The timetable module sequentially calls the construction elevator first-floor travel timetable model, construction elevator operation count model, and simulation model of the elevator status simulation module to obtain the construction elevator first-floor travel timetable that best meets the constraints of the project construction. The elevator status simulation module is used to perform real-time calculations using the construction elevator first-floor travel timetable model, construction elevator operation count model, and simulation model.

[0031] In a preferred embodiment of the digital construction elevator intelligent management system described in this invention, the operating timetable calculation module specifically calculates the following values ​​in sequence:

[0032] After the construction elevator reaches floor L for the i-th time, and after all the personnel and construction materials accompanying them have left the elevator, the remaining number of personnel and construction materials on the elevator is UiL:

[0033] ;

[0034] After the construction elevator reaches floor L for the i-th time, and after the personnel and construction materials accompanying them have left the elevator, the upper bound ViL is the number of personnel and construction materials that the construction elevator on floor L can still accommodate.

An upward construction elevator trip from the first floor to the top floor is counted as one trip according to the upward time axis, and a downward construction elevator trip from the top floor to the first floor is counted as one trip according to the downward time axis. The total number of trips by the construction elevator is the sum of the number of trips by the construction elevator from the first floor to the top floor on the upward time axis and the number of trips by the construction elevator from the top floor to the first floor on the downward time axis.

[0066] Using the waiting time for personnel and accompanying construction materials to the construction elevator as constraints, and the elevator's load capacity as another constraint, a dynamic optimization control chart for the construction elevator is established using a computer simulation method, based on a mathematical model of the elevator's first-floor travel timetable and a model of the number of elevator operations. Based on this dynamic optimization control chart, the optimal first-floor travel timetable and the number of elevator operations suitable for the specific construction project are selected.
