[0002] Power line carrier is a communication method unique to power systems. Power line carrier communication refers to the technology of using existing power lines to transmit analog or digital signals at high speed through carriers. Data transmission can be carried out without rebuilding the network.

[0003] Climbing frame refers to the attached lifting scaffolding used in construction, also called "climbing frame". It is a scaffolding system that relies on its own power system to climb up and down along the building structure. The construction site environment is complex, and laying dedicated communication lines will increase costs and difficulties. At this time, power line carrier communication technology can use the existing temporary building power supply network (power lines) to transmit control and monitoring data, and realize remote control and automatic monitoring of the climbing frame.

[0004] The stability of the climbing frame is very important. The climbing frame is usually used in the construction of high-rise buildings, and workers need to operate on the frame. If the climbing frame is not stable enough, it may cause tilting, shaking or even collapse, directly threatening the lives of construction workers. A stable climbing frame can ensure that workers are standing, walking and operating in a safe state during the construction process. In the prior art, the stability of the climbing frame is usually detected in real time, and no corresponding control is made in advance according to the trend of stability changes, which may increase safety hazards.

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] Figure 1 It is a flow chart of a climbing frame control method of a power line carrier according to the present invention. DETAILED DESCRIPTION

[0032] 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.

[0033] See also Figure 1 As shown, the present invention is a power line carrier climbing control method, including a ground control center, including the following steps:

[0034] S1: Acquire stability parameters of the climbing frame, wherein the stability parameters are parameters that affect the stability of the climbing frame, and send the stability parameters to a ground control center based on a power line carrier. In the ground control center, a stability score of the climbing frame is determined based on a superior-inferior solution distance method and the stability parameters;

[0035] S2: Periodically obtain the stability scores, sort them according to the time axis order to obtain a first order, and calculate the stability difference ΔD i =D i+1 -D i , D i represents the stability score of the ith position in the first ranking, and determines the change value X i , when the stability difference ΔD i-1 When <0, the change value X i =-1; when the stability difference ΔD i-1 >0, the change value Xi=1;

[0036] The change values ​​are sorted in time axis order to obtain a second sorting, and a judgment parameter is obtained based on the second sorting, wherein the judgment parameter includes the ratio of the number of change values ​​1 to the total number of change values ​​C + , the ratio of the number of change values ​​of -1 to the total number of change values ​​C - , the sort length L whose change value is continuously 1 + and the sort length L whose changing value is continuously -1 - ;

[0037] S3: Calculate the judgment value. When the judgment value is greater than or equal to a preset value, the ground control center sends a stability warning signal for prompting.

[0038] It should be noted that by collecting the stability parameters of the climbing frame, it is ensured that the key factors affecting the safety of the climbing frame can be monitored in real time. Only by mastering the actual operating status of the climbing frame can its safety and stability be evaluated. The power line carrier technology is used to send data to the ground control center, which can achieve stable data transmission without the need for additional communication infrastructure. This method reduces system costs while ensuring the stability of data transmission. By periodically obtaining and sorting the stability scores, the state changes of the climbing frame at different time points can be monitored to discover potential trends and anomalies. By analyzing the changing trends, the direction of continuous changes in the stability scores can be identified. This information helps to further analyze the overall operating status of the climbing frame and is an important factor in predicting future risks. The key steps are as follows; by counting the number of change values ​​1 and -1 and their continuous sorting length, the frequency and intensity of changes in the stability of the climbing frame can be determined. A change value of 1 indicates an increase in the stability score, and a change value of -1 indicates a decrease in the stability score. These parameters provide a basis for determining whether the climbing frame is in a potentially dangerous state; by segmenting the persistence of the statistical change trend, it can be seen whether the climbing frame is in a stable (continuously rising) or unstable (continuously declining) state, and the state changes of the climbing frame are visualized as specific judgment parameters, so that the system can evaluate the stability of the climbing frame with a basis to avoid false alarms or missed alarms; by accurately calculating the judgment value and setting a reasonable threshold, the system can issue a warning signal in time before the danger occurs, effectively ensuring the safe operation of the climbing frame.

[0039] In another preferred implementation of the present invention, in step S3, the process of calculating the judgment value specifically includes:

[0040] The judgment value K is calculated by the following formula:

[0041]

[0042] Wherein, η is a preset correction coefficient, and m represents the total number of stability scores obtained.

[0043] In another preferred implementation of the present invention, in the step S1, when the stability score is less than a preset score threshold, the ground control center sends a stability warning signal for prompting.

[0044] It is understandable that the preset score threshold is a safety limit, indicating that when the stability score is lower than this value, the operation of the climbing frame may be in an unsafe state, and the operators need to be warned in time so that they can take appropriate measures to prevent accidents, such as slowing down or stopping the operation, checking and repairing potential faults in the system, or strengthening the fixing and stabilization measures of the climbing frame.

[0045] In another preferred implementation of the present invention, the step S2 further includes the following steps:

[0046] determining the monotonicity of the first sorting;

[0047] When the first ranking is monotonically increasing, the ground control center does not send a stability warning signal;

[0048] When the first ranking is monotonically decreasing, the ground control center sends a stability warning signal for prompting.

[0049] It should be noted that a monotonic increase indicates that the stability score of the climbing frame is gradually increasing, the system status is continuously improving, and there is no dangerous trend; a monotonic decrease indicates that the stability score of the climbing frame is gradually decreasing, the system status is continuously deteriorating, and there is a potential risk of instability. At this time, a direct judgment can be made to save the time required for subsequent steps.

[0050] In another preferred embodiment of the present invention, in step S2, when the stability difference ΔD i = 0, remove the stability score of the i+1th position in the ranking and recalculate the stability difference ΔD i .

[0051] In another preferred implementation of the present invention, in the step S1, the stability parameters of the climbing frame are acquired based on sensors, and the stability parameters include inclination angle, vibration frequency and amplitude.

[0052] It can be understood that the inclination angle indicates the degree of inclination of the climbing frame relative to the building structure, usually expressed in degrees; the vibration frequency and amplitude respectively indicate the vibration amplitude and frequency generated by the climbing frame when it is in operation or under the influence of external forces. In actual situations, staff can choose to increase or decrease the number and types of stability parameters according to actual needs.

[0053] A climbing frame control system of a power line carrier includes a ground control center, including:

[0054] Acquisition module: acquiring stability parameters of the climbing frame, the stability parameters being parameters that affect the stability of the climbing frame, and sending the stability parameters to a ground control center based on a power line carrier, where a stability score of the climbing frame is determined based on a superior-inferior solution distance method and the stability parameters;

[0055] Analysis module: periodically obtain the stability scores, sort them according to the time axis to obtain the first sorting, and calculate the stability difference ΔD i =D i+1 -D i , D i represents the stability score of the ith position in the first ranking, and determines the change value X i , when the stability difference ΔDi-1 When <0, the change value X i =-1; when the stability difference ΔD i-1 >0, the change value Xi=1;

[0056] The change values ​​are sorted in time axis order to obtain a second sorting, and a judgment parameter is obtained based on the second sorting, wherein the judgment parameter includes the ratio of the number of change values ​​1 to the total number of change values ​​C + , the ratio of the number of change values ​​of -1 to the total number of change values ​​C - , the sort length L whose change value is continuously 1 + and the sort length L whose changing value is continuously -1 - ;

[0057] Early warning module: calculates the judgment value. When the judgment value is greater than or equal to the preset value, the ground control center sends a stability early warning signal for prompting.

[0058] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
