Description

Technical Field

[0001] The present invention relates to the field of lift technology, and specifically to an intelligent control system based on a lift.

Background Art

[0002] A lift is a vertical transportation device and is widely used in fields such as construction, warehousing, and industry. Thereby, smooth lifting and lowering between different floors of people and goods are realized by motor drive and mechanical transmission. The lift has characteristics such as a firm structure, simple operation, and high loading capacity, greatly improving work efficiency, ensuring transportation safety, and providing a convenient solution for various high-altitude operations and material transportation.

[0003] The invention patent with the application number 202111608853.X discloses a lift lifting safety intelligent operation control system including a lift. The system includes a collection module for collecting the weight and position data of a user entering the lift, a monitoring module for monitoring the stop position and operating state of the lift, an interaction module for interacting with the user to present the execution of control operations to the user, an alarm module for emitting an alarm signal to the user and presenting the execution of an emergency descent operation to the user when an emergency occurs, and a processor respectively and controllably connected to the collection module, the monitoring module, the interaction module, and the alarm module. The collection module includes a collection unit for collecting the actions of the user entering the lift and presenting to the user in cooperation with the alarm module and the interaction module, and a sensing unit for collecting the positions of the users in each lift. The sensing unit is provided on the bottom wall of the lift cabin and includes a sensing plate for collecting the weight of the user and several position sensing members distributed at equal intervals along the longitudinal direction of the sensing plate for collecting the standing positions of the users.

[0004] This application aims to solve the problem that "existing technology for lifts has a low level of intelligence, lacks emergency self-response capabilities, has insufficient self-diagnostic capabilities, and cannot intelligently perform human-machine interaction."

[0005] However, in the case of lifts used for transporting materials and cargo, the lifting and lowering of cargo and materials is often done manually controlled by humans. When a lift handles the task of transporting cargo and materials of different weights, the lift power is mostly fixed, and as a result, the operating cost of the lift is evaluated solely by the usage time, which leads to the problem of low energy efficiency during lift operation. [Overview of the Initiative] [Problems that the invention aims to solve]

[0006] In response to the aforementioned shortcomings of existing technologies, the present invention provides a lift-based intelligent control system that solves the technical problems raised in the background technology described above. [Means for solving the problem]

[0007] To achieve the above objectives, the present invention is realized by the following technical solutions.

[0008] An intelligent control system based on a lift, wherein the system is The system includes a main control unit, a control terminal for issuing execution commands, a collection module for collecting characteristic parameters of the objects to be transported by the lift, a setting module for acquiring the characteristic parameters of the objects to be transported by the lift and setting the lift's operation logic based on those parameters, a monitoring module for monitoring whether the most recently collected characteristic parameters of the objects to be transported by the lift by the collection module are reusable parameters, a drive module for receiving the lift's operation logic set in the setting module and applying that logic to control the lift's operation, and an output module for outputting lift operation messages.

[0009] Furthermore, a sub-module is provided below the aforementioned collection module. An identification unit for capturing the external appearance and quality of the transported object, Includes an identification unit for receiving the appearance image and quality of the transported object, and a storage unit for storing the appearance image and quality of the transported object, Here, the identification unit captures the appearance image and quality of the transported object, i.e., the characteristic parameters of the transported object. When the storage unit stores the appearance image and quality of the transported object, it synchronously compares the similarity between the appearance image and quality of the transported object to be stored and the appearance image and quality of the transported object already stored in the storage unit. If similar items are found as a result of the comparison, the appearance image and quality of the transported object to be stored are discarded.

[0010] Furthermore, the similarity of the appearance image and quality of the transported object is calculated using the following formula:

[0012] Furthermore, the operating logic set for the lift in the aforementioned setting module includes the lifting height and the motor power when the lift is lifting and lowering for transport. In the operating logic set for the aforementioned lift, the lifting height is set by the system user, and the motor power used when the lift is raised and lowered for transport is pre-calculated and applied based on the characteristic parameters of the transported object.

[0014] Furthermore, the monitoring module monitors whether the characteristic parameters of the transportation target of the lift newly collected by the collection module are reuse parameters, that is, operates the operation of monitoring the comparison result of the similarity between the appearance image and quality of the transportation target to be stored in the storage unit and the appearance image and quality of each group of transportation targets stored in the storage unit. If there is one group of appearance images and quality of transportation targets with a similarity greater than 95%, the monitoring result of the monitoring module is "yes"; otherwise, the monitoring result of the monitoring module is "no". When the monitoring result of the monitoring module is "yes", the calling unit is triggered to operate.

Moreover, through the control of the operation power of the lift, the energy-saving management of the operation is further realized, and the operation cost of the lift is no longer restricted by the operation time.

[0018] To more clearly explain the technical solutions in the embodiments of the present invention or the prior art, hereinafter, the drawings necessary for describing the embodiments or the prior art will be briefly introduced. Obviously, the drawings described below are only some embodiments of the present invention, and those skilled in the art can obtain other drawings based on these drawings without creative labor. [Figure 1] It is a schematic structural diagram of an intelligent control system based on a lift.

Modes for Carrying Out the Invention

[0019] To further clarify the object, technical solution, and advantages of the embodiments of the present invention, the technical solution in the embodiments of the present invention will be described clearly and completely below with reference to the drawings of the embodiments. It is clear that the described embodiments are only a selection of embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art without creative work based on the embodiments of the present invention are all within the scope of protection of the present invention.

[0020] The present invention will be further described below with reference to the examples.

[0021] (Example 1) The intelligent control system based on the lift in this embodiment includes a control terminal, a data collection module, a configuration module, a monitoring module, a drive module, and an output module, as shown in Figure 1. The control terminal is the main control unit of the system and is used to issue execution commands. The collection module is used to collect characteristic parameters of the objects transported by the lift. Below the collection module, An identification unit for capturing the external appearance and quality of the transported object, A submodule is provided which includes a storage unit for receiving the appearance image and quality of the transported object captured by the identification unit and for storing the appearance image and quality of the transported object. Here, the identification unit captures the appearance image and quality of the transported object, i.e., the characteristic parameters of the transported object. When the storage unit stores the appearance image and quality of the transported object, it synchronously compares the similarity between the appearance image and quality of the transported object to be stored and the appearance image and quality of the transported object already stored in the storage unit. If similar items are found as a result of the comparison, the appearance image and quality of the transported object to be stored are discarded. The similarity of the appearance image and quality of the transported items is calculated using the following formula:

number

[0022] In this embodiment, the control terminal controls and operates the collection module to collect characteristic parameters of the objects to be transported by the lift. During the operation phase of the collection module, the identification unit synchronously captures the appearance image and quality of the objects to be transported. The storage unit receives the appearance image and quality of the objects captured by the identification unit in real time and stores the appearance image and quality of the objects to be transported. Subsequently, the setting module operates to acquire the characteristic parameters of the objects to be transported by the lift and sets the operation logic of the lift based on the characteristic parameters of the objects to be transported. The binding unit synchronously receives the pre-calculated motor power results when the lift is moving up and down from the setting module, applies the pre-calculation results to the lift, and further feeds the pre-calculation results back to the storage unit, which then retrieves the appearance image and quality of similar objects to be transported stored in the storage unit, or attempts to store them. The monitoring module binds to similar transport object appearance images and quality, and further monitors whether the most recently collected feature parameters of the lift transport object by the collection module are reuse parameters. If the monitoring module's result is "yes", the calling unit retrieves from the storage unit pre-calculated results bound to transport object appearance images and quality with a similarity of more than 95% to the transport object appearance image and quality to be stored. If the monitoring module's result is "no", the jump unit activates to jump to the activation of the setup module, after which the drive module receives the lift operation logic set in the setup module, applies the lift operation logic to control the lift operation, and finally outputs a lift operation message via the output module.

[0023] The system in the above embodiment enables intelligent control of the lift's operating power, thereby allowing the lift to stably perform lifting and lowering transport tasks while reducing energy waste due to operating power.

[0024] (Example 2) In terms of specific implementation, this embodiment will provide a more detailed explanation of the lift-based intelligent control system in Embodiment 1, based on Embodiment 1 and with reference to Figure 1.

[0025] The operating logic set for the lift in the configuration module includes the lifting height and the motor power used when the lift is moving up and down. In the operating logic set for the lift, the lifting height is set by the system user, and the motor power used when the lift is lifting and lowering is pre-calculated and applied based on the characteristic parameters of the transported object. The motor power required for lifting and lowering during transport is calculated in advance using the following formula:

number

[0026] In this embodiment, the above-described setup limits the pre-calculation logic for motor power during transport when the lift is raised or lowered, and based on the operation of the binding unit, the pre-calculation results are bound and stored with the appearance image and quality parameters of the transported object stored in the storage unit.

[0027] (Example 3) In terms of specific implementation, this embodiment will provide a more detailed explanation of the lift-based intelligent control system in Embodiment 1, based on Embodiment 1 and with reference to Figure 1.

[0028] The monitoring module operates to monitor whether the feature parameters of the transported objects of the lift most recently collected by the collection module are reusable parameters. Specifically, it monitors the comparison of the similarity between the appearance image and quality of the transported object to be stored in the storage unit and the appearance image and quality of the transported objects of each group stored in the storage unit. If the comparison results show that there is one group of transported object appearance images and quality with a similarity greater than 95%, the monitoring module's result is "yes." Conversely, if the similarity is greater than 95%, the monitoring module's result is "no." If the monitoring module's monitoring result is "yes", the call unit is triggered and starts operating. The calling unit is used to retrieve pre-calculated results from the storage unit that are bound to the appearance image and quality of the transport object to be stored, and whose similarity to the appearance image and quality of the transport object to be stored is greater than 95%. If the monitoring module's monitoring result is "No", the jump unit is triggered and activated. The jump unit is used to jump to and activate the configuration module; While the call unit is running due to being triggered, after the call unit's operation ends, the drive module continues to operate. With the jump unit triggered and operating, the system proceeds to the operation phase of the configuration module, and after the configuration module has finished operating, the drive module then starts operating.

[0029] In this embodiment, the above-described installation provides further operational logic support to the system in Embodiment 1, and the installation in Embodiment 3 further assists the system in Embodiment 1, ensuring that continuous intelligent control of the lift can be achieved.

[0030] In summary, the system in the above embodiment collects visual images and quality parameters of the transported object during operation, thereby setting a targeted operating logic for the lift. This controls the lift's operating power, achieving the objective of matching the lift's operating power to the transport target. As a result, the lift's operating power is adjusted according to the actual conditions of the transported object, ultimately achieving intelligent control of the lift's operating power. Furthermore, this control of the lift's operating power enables energy-saving management of the operation, and the lift's operating cost is no longer limited by operating time.

[0031] The above embodiments are merely for illustrating, and not limiting, the technical solutions of the present invention. While the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that it is still possible to modify the technical solutions described in the above embodiments or to make equivalent substitutions to some of their technical features, and that such modifications or substitutions do not deviate from the spirit and scope of the technical solutions of the respective embodiments of the present invention.
