Description

Technical Field

[0001] This invention relates to the field of construction equipment control technology, and in particular to a control method, device and electronic equipment for a construction hoist. Background Technology

[0002] Construction hoists are crucial vertical transportation equipment used in building construction to transport personnel and materials. Currently, construction hoists typically require specialized operators for operation and control, but this traditional method has several drawbacks. Firstly, operators are prone to fatigue from prolonged work, potentially leading to operational errors and compromising the safe operation of the hoist. Secondly, manual operation increases construction costs. With the development of artificial intelligence and automation technologies, achieving intelligent and unmanned operation of construction hoists has become an industry trend, thus necessitating a smart control method for construction hoists. Summary of the Invention

[0003] The purpose of this invention is to provide a construction hoist control method, device, and electronic equipment to alleviate the technical problems of high labor costs and error rates in the control of construction hoists in the prior art, and to improve the operating efficiency of construction hoists.

[0004] In a first aspect, the present invention provides a construction hoist control method, comprising: receiving a user's call request and determining the target floor to which the call request belongs; determining a target hoist cage for responding to the call request based on the target floor; after determining that the target hoist cage has reached the target floor and all users have entered the target hoist cage, acquiring ambient wind speed and load data of the target hoist cage; and, if it is determined that the ambient wind speed is less than a preset wind speed threshold and the load data is less than a preset load threshold, determining the operating speed at which the target hoist cage moves to the user-specified floor based on the ambient wind speed and load data.

[0005] In an optional implementation, determining the target hoist cage for responding to the call request based on the target floor includes: acquiring ambient wind speed, the height of the guide rail frame of the construction hoist, and load data and coordinate data of the two hoist cages of the construction hoist; determining a dynamic height difference threshold between the two hoist cages based on the ambient wind speed, guide rail frame height, and load data; and determining the target hoist cage for responding to the call request based on the dynamic height difference threshold, coordinate data, and target floor, with reducing the height difference between the two hoist cages as the priority scheduling condition.

[0006] In an optional implementation, after determining the target hoist cage for responding to the call request, the method further includes: during the movement of the target hoist cage, calculating in real time the height difference between the target hoist cage and another hoist cage to obtain a target difference value; if the target difference value gradually increases and approaches a dynamic height difference threshold, then obtaining the operating status of the other hoist cage; if the other hoist cage is in an unloaded state, then adjusting the movement position of the other hoist cage to keep the height difference between the target hoist cage and the other hoist cage within the dynamic height difference threshold; if the other hoist cage is in a working state, then adjusting the movement status of the hoist cage with the relatively lower priority among the target hoist cage and the other hoist cage to keep the height difference between the target hoist cage and the other hoist cage within the dynamic height difference threshold.

[0007] In an optional implementation, each hoist cage is equipped with distance sensors at its top and bottom edges facing the building. After determining the target hoist cage for responding to a call request based on the target floor, the method further includes: acquiring coordinate data of the target hoist cage; if the distance between the target hoist cage and the target floor is determined to be less than a first distance threshold based on the coordinate data, activating the distance sensors on the target hoist cage to acquire the distances between the top and bottom edges of the target hoist cage and the building; if the target hoist cage is in a downward state, after the distance between the bottom distance sensor and the building is less than a second distance threshold and then jumps to a value greater than the second distance threshold, and the distance between the top distance sensor and the building is less than the second distance threshold, determining that the target hoist cage has reached the target floor; if the target hoist cage is in an upward state, after the distance between the top distance sensor and the building is less than the second distance threshold and then jumps to a value greater than the second distance threshold, and the distance between the bottom distance sensor and the building is less than the second distance threshold, determining that the target hoist cage has reached the target floor.

[0008] In an optional embodiment, a millimeter-wave radar device is installed on the outside of the cage, a tilt sensor is installed at the top inside the cage, and strain gauges are installed at the four corners of the bottom of the cage support. The millimeter-wave radar device, tilt sensor, and strain gauges are all connected to a host computer. The millimeter-wave radar device is used to monitor the distance between objects around the cage and the cage in real time. When it is determined that a foreign object is gradually approaching the cage, it sends a first warning signal to the host computer so that the host computer can control the cage to stop running before the foreign object intrudes into the cage. The tilt sensor is used to monitor the tilt angle of the cage in real time. When it is determined that the tilt angle of the cage is greater than a preset tilt angle threshold, it sends a second warning signal to the host computer so that the host computer can control the cage to stop running. The strain gauges are used to monitor the pressure at the bottom corners of the support and feed the pressure value back to the host computer. When the host computer determines that the deviation of the pressure value change at the four bottom corners is greater than a preset threshold, it controls the cage to stop running.

This represents the wind speed attenuation coefficient. Indicates ambient wind speed. This indicates the preset wind speed threshold. This represents the nonlinear exponent of wind speed.

[0012] Thirdly, the present invention provides an electronic device, including a memory and a processor, wherein the memory stores a computer program that can run on the processor, and the processor executes the computer program to implement the construction hoist control method described in any of the foregoing embodiments.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0018] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0019] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0020] Example 1 Figure 1 A flowchart of a construction hoist control method provided in an embodiment of the present invention is shown below. Figure 1 As shown, the method specifically includes the following steps: Step S102: Receive the user's call request and determine the target floor to which the call request belongs.

[0021] Step S104: Determine the target hoist cage for responding to the call request based on the target floor.

[0022] The construction hoist control method provided in this invention aims to eliminate the traditional construction hoist operator position and intelligently control the construction hoist to operate safely, stably, and efficiently through a preset algorithm process.

[0023] Before the construction hoist starts operation, a self-inspection should be performed. The self-inspection items should include at least: whether the cage door and landing door open and close normally, whether there are foreign objects on the guide rails, the no-load / initial load, and whether the cage door and landing door are interlocked. Once it is confirmed that the doors open and close normally, there are no foreign objects on the guide rails, the cage door and landing door are interlocked, and the hoist is unloaded, it can be started. The above self-inspection items can be performed by configuring sensing devices / sensors to send the feedback detection data (numerical and / or image data) to a host computer. The host computer then determines whether the self-inspection passes based on the detection data. The host computer is also the executing entity of the method provided in this embodiment of the invention.

[0024] After the construction hoist starts operating, it can receive and respond to user call requests. Specifically, when a user sends a call request, the host computer can determine the target floor corresponding to the request, that is, determine which floor requires the use of the hoist cage. In this embodiment of the invention, the construction hoist refers to a device with two independent hoist cages on a guide rail frame. Therefore, after receiving a call request, the host computer should select one hoist cage from the two hoist cages to respond to the call request according to a preset control strategy, that is, determine the target hoist cage. This embodiment of the invention does not specifically limit the preset control strategy. Users can refer to the response strategy of passenger elevators in the prior art, or simply determine the target hoist cage according to the principle of proximity, etc.

[0025] Step S106: After confirming that the target hoist cage has reached the target floor and all users have entered the target hoist cage, acquire the ambient wind speed and the load data of the target hoist cage.

[0026] Step S108: If the ambient wind speed is less than the preset wind speed threshold and the load data is less than the preset load threshold, determine the operating speed of the target cage to move to the user-specified floor based on the ambient wind speed and load data.

[0027] In existing technologies, hoist cage movement typically employs a fixed operating speed. This method, to some extent, limits the operational efficiency of construction hoists. Therefore, this invention proposes a strategy for dynamically adjusting the hoist cage's operating speed. Once a user enters the hoist cage, if it is determined that there is no overload and the ambient wind speed does not reach a preset wind speed threshold, the operating speed at which the target hoist cage will transport the user to their designated floor is calculated based on the current ambient wind speed and the load data of the target hoist cage. Higher wind speeds and heavier loads result in lower operating speeds. To balance operational safety and efficiency, a combination of exponential decay and polynomial coupling can be used to achieve a synergistic effect of wind speed and load on the operating speed.

[0028] If the hoist cage is overloaded and / or the ambient wind speed exceeds a preset wind speed threshold, the hoist cage will be stopped to ensure safety. Ambient wind speed can be measured by installing a meteorological sensor on the outside of the hoist cage or at a designated location on the construction hoist. Furthermore, during hoist cage operation, if a sudden strong wind occurs and the meteorological sensor detects a sharp increase in ambient wind speed exceeding the preset wind speed threshold, the host computer can choose to keep the hoist cage stationary or move it at a preset minimum operating speed to the nearest floor to allow the user to escape. Further, if the meteorological sensor is capable of detecting various severe weather conditions, the control logic following a sudden strong wind can be referenced; when extreme weather affecting the safe operation of the hoist cage is determined, the movement of the hoist cage can be stopped immediately.

[0029] The construction hoist control method provided in this invention eliminates the need for traditional construction hoist operators, reducing labor costs and avoiding human error. Furthermore, the hoist cage's operating speed can be dynamically adjusted based on ambient wind speed and load data. Compared to traditional fixed operating speeds, this method improves the operating efficiency of the construction hoist while ensuring its safe operation.

[0030] In one alternative implementation, such as Figure 2 As shown, step S104 above, which determines the target hoist cage for responding to the call request based on the target floor, specifically includes the following steps: Step S1041: Obtain ambient wind speed, height of the guide rail frame of the construction hoist, load data and coordinate data of the two cages of the construction hoist.

[0031] Step S1042: Based on the ambient wind speed, guide rail height, and load data, determine the dynamic height difference threshold between the two cages.

[0032] Step S1043: Based on the dynamic height difference threshold, coordinate data, and target floor, the target hoist is determined to respond to the call request with the priority scheduling condition of reducing the height difference between the two hoists.

[0033] Specifically, given that a double-cage construction hoist consists of two independently operating cages mounted on a guide rail frame, when the height difference between the two cages is too large, the eccentric load on the guide rail frame increases significantly. In extreme cases (such as one cage at the top and the other at the bottom), the center of gravity of the entire system shifts severely, the anti-overturning stability decreases sharply, and operational safety is affected. Generally, the maximum height difference between the two cages is fixed, but this fixed height difference design has significant limitations on the operational efficiency of some construction scenarios.

[0034] To ensure the safe and efficient operation of the hoist cages, this invention proposes the concept of a dynamic height difference threshold. Specifically, based on ambient wind speed, guide rail height, and load data, the height difference threshold between the two hoist cages is dynamically determined. In other words, given a fixed guide rail height, the safe height difference between the hoist cages is dynamically adjusted based on the ambient wind speed and their respective load data.

[0035] In one alternative implementation, the formula for the dynamic height difference threshold between the two cages is: ; This indicates the preset static height difference threshold. This indicates the load difference ratio between the two cages. , These represent the load data for the two hoist cages, Indicates the preset load threshold. Indicates the load difference ratio threshold. Indicates ambient wind speed. This indicates the preset wind speed threshold. Indicates the height of the guide rail bracket. Indicates the guide rail height threshold. , , All represent preset weighting coefficients.

[0036] Based on the above formulas, it can be seen that the greater the ambient wind speed, the greater the load difference ratio between the two cages, and the higher the guide rail frame, the smaller the dynamic height difference threshold between the two cages. The aforementioned preset weighting coefficients can be set empirically, or they can be used as model optimization parameters and determined after training the model with a large amount of measured data.

[0037] Based on the coordinate data of the two hoist cages and the target floor for sending the call request, the relative positional relationship between the user and the two hoist cages can be determined. To ensure a safe height difference between the hoist cages, the host computer calculates the vertical distance between the two hoist cages multiple times per second. After calculating the dynamic height difference threshold between the two hoist cages, this embodiment of the invention selects the hoist cage that can reduce the height difference between the two hoist cages as the target hoist cage for priority scheduling.

[0038] To facilitate understanding, the following example illustrates that, based on the method provided in this embodiment of the invention, the height difference between the two hoists is ensured to be within the corresponding dynamic height difference threshold at any given time. Therefore, if the target floor is located between the floors where the two hoists are located, then either hoist can obviously reduce the height difference between the two hoists by using either hoist as the target hoist. Thus, the host computer can randomly select one of them as the target hoist, or select the hoist closest to the target floor as the target hoist. If the target floor is located above the floors where the two hoists are located, then, unlike the response strategy of traditional passenger elevators, in order to avoid the height difference between the hoists increasing and affecting the safety of elevator operation, the lower hoist moves upward to respond to the user's call request, that is, the lower hoist is the target hoist. Similarly, if the target floor is located below the floors where the two hoists are located, the higher hoist moves downward, that is, the higher hoist is the target hoist.

[0039] To ensure that the height difference between the two cages is within the corresponding dynamic height difference threshold at any given time, thereby improving the operational safety of the two cages of the construction hoist, after determining the target cage for responding to the call request, the embodiments of the present invention further include the following: During the movement of the target cage, the height difference between the target cage and another cage is calculated in real time to obtain the target difference value.

[0040] If the target difference gradually increases and approaches the dynamic height difference threshold, then the operating status of the other cage is obtained.

[0041] If the other cage is unloaded, adjust the position of the other cage to keep the height difference between the target cage and the other cage within the dynamic height difference threshold.

[0042] If the other cage is in operation, adjust the movement state of the target cage and the cage with the lower priority among the other cages to keep the height difference between the target cage and the other cage within the dynamic height difference threshold.

[0043] In other words, during the movement of the target hoist cage, if the height difference between the hoist cages approaches the dynamic height difference threshold, the movement state of one of the two hoist cages needs to be adjusted to ensure that the height difference no longer increases. Specifically, if the other hoist cage is not occupied, its movement direction is immediately adjusted to follow the movement direction of the target hoist cage to maintain the height difference between them; however, if the other hoist cage is also in operation, it is necessary to ensure that the higher-priority hoist cage is delivered to the user first. That is, the lower-priority hoist cage passively adjusts its movement state to follow the higher-priority hoist cage to maintain the height difference between them. After the higher-priority hoist cage completes its transport task, the lower-priority hoist cage continues to perform its transport task.

[0044] In this embodiment of the invention, the priority of the hoist cage is not specifically limited. It can be specified in advance, or a user priority authentication device can be deployed in the hoist cage. After the user enters the hoist cage, priority authentication must be performed first, and then the destination floor to be reached must be specified. At this time, the priority of the hoist cage is the highest priority among the users it carries.

[0045] During the process of moving the target cage to the target floor, its spatial position can be roughly determined based on the cage's coordinates. However, given the deviation in coordinate data collection, it is difficult to maintain high leveling accuracy based solely on the cage's coordinate data. If the height deviation between the bottom of the cage and the floor plane is large when the cage stops at the target floor, it will inevitably affect the safety of users getting on and off the cage.

[0046] In view of this, in an optional embodiment, distance sensors are provided at the top and bottom of the outer edge of each hoist cage facing the building. After determining the target hoist cage for responding to the call request based on the target floor, the embodiment of the present invention further includes the following: Obtain the coordinate data of the target cage.

[0047] If the distance between the target hoist cage and the target floor is determined to be less than a first distance threshold based on coordinate data, the distance sensor on the target hoist cage is activated to obtain the distance between the top and bottom edges of the target hoist cage and the building.

[0048] If the target cage is in a downward state, after the distance between the bottom distance sensor and the building is less than the second distance threshold and then jumps to be greater than the second distance threshold, when the distance between the top distance sensor and the building is less than the second distance threshold, it is determined that the target cage has reached the target floor.

[0049] If the target cage is in an upward state, after the distance between the top distance sensor and the building is less than the second distance threshold and then jumps to be greater than the second distance threshold, when the distance between the bottom distance sensor and the building is less than the second distance threshold, it is determined that the target cage has reached the target floor.

[0050] Specifically, in this embodiment of the invention, distance sensors are configured at the top and bottom of the outer edge of the hoist cage facing the building. The principle described above for determining whether the target hoist cage has reached the target floor is as follows: when the edge of the hoist cage moves to the floor slab, the distance between the distance sensor deployed along that edge and the building is relatively small; however, when the edge of the hoist cage moves to the landing door opening, the distance between the distance sensor and the building is relatively large. This embodiment of the invention is based on the distance changes sensed by the distance sensors during the hoist cage's up-and-down movement between floors, and the above-mentioned execution strategy is designed accordingly.

[0051] It should be noted that the precise installation position of the top / bottom distance sensor needs to be adaptively set according to the actual floor thickness and the width of the hoist cage edge. This is so that when the hoist cage is moving up or down, the change in the transient distance measurement result of the top / bottom distance sensor described above can immediately trigger the target hoist cage to stop running. This ensures that when the target hoist cage reaches the target floor, the height deviation between the bottom surface of the hoist cage and the floor plane is maintained within a very small range (±2mm), thereby improving the leveling accuracy of the hoist cage when it reaches each floor.

[0052] After the target hoist cage reaches the target floor, the user enters the target hoist cage. As described above, in this embodiment of the invention, if it is determined that the target hoist cage is not overloaded and the wind speed does not exceed a preset wind speed threshold, the operating speed of the target hoist cage under the current load needs to be calculated. In an optional embodiment, the formula for the operating speed of the target hoist cage moving to the user-specified floor is: ;in, This indicates the rated maximum speed at which the target cage moves. This represents the wind speed attenuation coefficient, used to control the attenuation rate. The larger the value, the more sensitive the wind speed effect. Indicates ambient wind speed. This indicates the preset wind speed threshold. This represents the nonlinear exponent of wind speed, with a value greater than 1, used to achieve rapid attenuation near the threshold region. This represents the minimum load compensation coefficient, used to ensure that there is still a base speed under heavy load (to prevent stalling). This indicates the load ratio of the target cage. , This indicates the actual load on the target cage. Indicates the preset load threshold. This represents the load nonlinearity index, with a value greater than 1, used to enhance the heavy load penalty effect. Represents the load saturation constant, so that When =1, the load term decreases to approximately .

[0053] In this embodiment, the formula for operating speed can be decomposed into a wind speed attenuation term. and load adaptation items According to the expression for the wind speed attenuation term, at low ambient wind speeds (e.g., ), the operating speed does not decrease significantly; at medium wind speeds (e.g. The operating speed decreases to some extent; at high wind speeds (e.g.) This can lead to an exponential collapse, with a sharp decrease in operating speed. For example, if... The value is 2.5. If the value is 3, the calculated result of the wind speed attenuation term is about 1 when the wind speed is low, and about 0.3 when the wind speed is high, which means the speed is reduced by 70%.

[0054] According to the expression for the load adaptation term, when the cage is lightly loaded (e.g., The operating speed remains essentially unchanged when the cage is under load (e.g., when the cage is loaded with load). The operating speed will decrease to some extent when the cage is heavily loaded (e.g., when the cage is under heavy load). The running speed will decrease sharply. For example, if The value is 0.4. The value is 1.8. If the value is 1.2, the calculated result of the load adaptation term is approximately 1 under light load, while under heavy load, the calculated result of the load adaptation term is approximately 0.5, that is, maintaining 50% of the base speed.

[0055] In one alternative embodiment, to further improve the operational safety of the construction hoist, a millimeter-wave radar device is installed on the outside of the cage, a tilt sensor is installed at the top inside the cage, and strain gauges are installed at the four corners of the bottom of the cage support; the millimeter-wave radar device, the tilt sensor, and the strain gauges are all connected to a host computer.

[0056] Millimeter-wave radar equipment is used to monitor the distance between objects around the hoisting cage and the hoisting cage in real time. When it is determined that a foreign object is gradually approaching the hoisting cage, it sends a first warning signal to the host computer so that the host computer can control the hoisting cage to stop operating before the foreign object invades the hoisting cage.

[0057] The tilt sensor is used to monitor the tilt angle of the hoist cage in real time. When it is determined that the tilt angle of the hoist cage is greater than the preset tilt angle threshold, a second warning signal is sent to the host computer so that the host computer can control the hoist cage to stop running.

[0058] Strain gauges are used to monitor the pressure at the base corners of the support structure and feed the pressure values ​​back to the host computer. If the host computer determines that the deviation in pressure values ​​at the four base corners exceeds a preset threshold, it will control the cage to stop operating. In other words, the purpose of installing strain gauges at each base corner of the cage support is to monitor the foundation settlement of the support in real time. If inconsistent pressure changes are detected at the base corners—for example, if the pressure at one base corner is significantly higher than the others—it is determined that the cage support is at risk of tilting, and to ensure safety, the cage operation should be terminated immediately.

[0059] Furthermore, to ensure the safety of users getting on and off the hoist cage, visual sensors can be installed inside and outside the hoist cage door. When the hoist cage reaches the designated floor, the hoist cage door and the floor door will automatically open. After confirming that personnel and goods have completely left / entered the hoist cage, the doors will automatically close, and the hoist cage door and the floor door will be interlocked for confirmation.

[0060] To further enhance the operational safety of construction hoists, cameras / laser scanners can be installed on the guide rails to monitor for issues such as foreign objects, structural deformation, and corrosion. Once an abnormality is detected, it will be immediately reported to the host computer, thereby triggering appropriate safety response strategies.

[0061] Furthermore, the host computer can also run algorithms to predict the remaining lifespan and potential failures of key components on the construction hoist (e.g., motors, gears, wire ropes / racks, brakes, bearings, etc.). Optionally, a neural network model can be used to predict the remaining lifespan and potential failures of key components on the construction hoist, so as to remind workers to perform equipment maintenance in advance to avoid sudden failures. This embodiment of the invention does not specifically limit the method for predicting the remaining lifespan / potential failures of key components; users can choose any existing method with this function.

[0062] Example 2 This invention also provides a construction hoist control device, which is mainly used to execute the construction hoist control method provided in Embodiment 1 above. The construction hoist control device provided in this invention will be described in detail below.

[0063] Figure 3 A functional block diagram of a construction hoist control device provided in an embodiment of the present invention is shown below. Figure 3 As shown, the device mainly includes: a receiving module 10, a first determining module 20, an acquiring module 30, and a second determining module 40, wherein: The receiving module 10 is used to receive the user's call request and determine the target floor to which the call request belongs.

[0064] The first determining module 20 is used to determine the target cage for responding to the call request based on the target floor.

[0065] The acquisition module 30 is used to acquire ambient wind speed and load data of the target hoist cage after determining that the target hoist cage has reached the target floor and all users have entered the target hoist cage.

[0066] The second determining module 40 is used to determine the operating speed of the target cage to move to the user-specified floor based on the ambient wind speed and load data when the ambient wind speed is less than a preset wind speed threshold and the load data is less than a preset load threshold.

[0067] The construction hoist control device provided in this invention eliminates the need for traditional construction hoist operators, reducing labor costs and avoiding human error. Furthermore, the cage's operating speed can be dynamically adjusted based on ambient wind speed and load data. Compared to traditional fixed operating speeds, this device improves the operating efficiency of the construction hoist while ensuring its safe operation.

[0068] Optionally, the first determining module 20 is specifically used for: Acquire ambient wind speed, the height of the guide rail frame of the construction hoist, and the load and coordinate data of the two cages of the construction hoist.

[0069] Based on environmental wind speed, guide rail height, and load data, the dynamic height difference threshold between the two cages is determined.

[0070] Based on dynamic height difference threshold, coordinate data, and target floor, the target cage for responding to call requests is determined with reducing the height difference between the two cages as the priority scheduling condition.

[0071] Optionally, the device is also used for: During the movement of the target cage, the height difference between the target cage and another cage is calculated in real time to obtain the target difference value.

[0072] If the target difference gradually increases and approaches the dynamic height difference threshold, then the operating status of the other cage is obtained.

[0073] If the other cage is unloaded, adjust the position of the other cage to keep the height difference between the target cage and the other cage within the dynamic height difference threshold.

[0074] If the other cage is in operation, adjust the movement state of the target cage and the cage with the lower priority among the other cages to keep the height difference between the target cage and the other cage within the dynamic height difference threshold.

[0075] Optionally, distance sensors are installed on the top and bottom of the outer edge of each cage facing the building. This device is also used for: Obtain the coordinate data of the target cage.

[0076] If the distance between the target hoist cage and the target floor is determined to be less than a first distance threshold based on coordinate data, the distance sensor on the target hoist cage is activated to obtain the distance between the top and bottom edges of the target hoist cage and the building.
