Description

Technical Field

[0001] The invention relates to the technical field of road and bridge construction, and in particular to an automatic control method for rotation that can be started with one button. Background Art

[0002] In the construction and installation of large bridges, buildings and heavy machinery and equipment, the rotation construction method is widely used due to its flexibility, efficiency and safety. Traditional rotation construction often relies on manual operation and experience judgment, which not only increases the difficulty and cost of construction, but also makes it difficult to ensure the accuracy and safety of the rotation process. Therefore, it is particularly important to develop a method that can achieve one-button start and automatic control of the rotation process.

[0003] Most of the existing rotation construction control methods have the following problems: First, there is a lack of systematic monitoring and feedback mechanism, and the key parameters of the rotation process cannot be obtained in real time, which makes it difficult to predict and control construction risks; second, the speed control is not accurate, and the speed changes during starting, running and stopping are difficult to achieve a smooth transition, affecting the stability and efficiency of the rotation construction; third, there is a lack of automatic correction function, and the deviation of the rotation angle is difficult to be corrected in time, affecting the construction accuracy; fourth, the fault diagnosis and alarm functions are not perfect. Once a fault occurs, it is difficult to detect and deal with it in time, which may cause a safety accident. Summary of the invention

[0004] The object of the present invention is to provide a method for automatically controlling a rotation body by starting it with one key, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a method for realizing automatic control of rotation by one-key start, the method comprising the following steps: 1 to 4 monitoring systems are set up to provide monitoring data only during the rotation process; The rotation angle is preset in the control host, and the rotation angle data is provided in real time through the angle monitoring system. When the rotation angle does not reach the preset value, the drive system continues to work.

[0006] Preferably, it also includes: The control host controls the speed of the rotation process according to the settings of the rotation start speed, average speed and maximum speed; In the first minute after the rotation starts, run at the starting speed; After all data are normal, it will automatically adjust to the preset average speed; The maximum speed is used as the upper limit of the speed during the rotation process.

[0007] Preferably, the speed control further comprises: If the rotation process stops due to abnormal circumstances, after restarting, the rotation speed will be adjusted according to the time limit, but not exceeding the maximum speed.

[0008] Preferably, it also includes: The pressure monitoring system monitors the pressure under the support leg in real time and sets the pressure limit value to 2000KN in the control host; When the monitored pressure exceeds 2000KN, the drive system stops working.

[0009] Preferably, it also includes: The stress monitoring system monitors the concrete stress value under the ball joint in real time and sets the stress limit value in the control host; When the monitored stress value exceeds the limit value, the drive system stops working.

[0010] Preferably, the pressure and stress monitoring are not controlled by the control host, and when any monitoring value exceeds the limit value, the oil pump drive motor will be stopped.

[0011] Preferably, it also includes: When the rotation process cannot be completed within the specified time due to lack of time, a time shortage warning is issued.

[0012] Preferably, it also includes an automatic deviation correction function: Based on the rotation angle information fed back by the angle sensor, the control host calculates the deviation between the actual rotation angle and the preset target angle in real time; When the deviation exceeds the allowable range, the control host automatically adjusts the direction and speed of the drive motor to achieve automatic correction.

[0013] Preferably, speed adaptive control is also included: According to the speed data collected by the speed sensor and the load changes during the rotation process, the control host automatically adjusts the output power of the drive motor to keep the rotor at a stable and reasonable speed.

[0014] Preferably, it also includes fault diagnosis and alarm functions: The control host continuously monitors the data of each sensor and the working status of each component; When a sensor failure, motor abnormality, or communication interruption is detected, the fault information is displayed on the display terminal, and an alarm signal is sent to the remote monitoring center. At the same time, emergency measures are taken, such as stopping the rotation operation.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The automatic control method for rotation that can be started with one button proposed in the present invention effectively solves the problems existing in the prior art through innovative points such as system monitoring and feedback, precise speed control, automatic deviation correction function, speed adaptive control, fault diagnosis and alarm function, one-button start and automatic control, and improves the accuracy, stability and safety of rotation construction, with significant social and economic benefits.

[0016] By setting up 1 to 4 monitoring systems, key parameters in the rotation process, such as angle, pressure, stress, etc., can be obtained in real time to provide accurate data support for construction control. These monitoring systems can monitor changes in the rotation process in real time, detect potential risks in a timely manner, and ensure the stability and safety of the construction process.

[0017] The control host precisely controls the rotation process according to the preset rotation start speed, average speed and maximum speed. A slower speed is used in the startup phase to ensure a smooth start; the preset average speed is used in the normal operation phase to improve construction efficiency; at the same time, the maximum speed is set as the speed limit to prevent safety risks caused by excessive speed. If the rotation process stops due to abnormal conditions, the rotation speed can be adjusted according to the time limit after restarting to ensure that the rotation is completed within the specified time.

[0018] Based on the rotation angle information fed back by the angle sensor, the control host can calculate the deviation between the actual rotation angle and the preset target angle in real time, and automatically adjust the direction and speed of the drive motor to achieve automatic deviation correction. This function ensures accurate control of the rotation angle and improves construction accuracy.

[0019] According to the speed data collected by the speed sensor and the load changes during the rotation process, the control host can automatically adjust the output power of the drive motor to keep the rotation at a stable and reasonable speed. This function makes the rotation process more stable and efficient, reducing energy consumption and wear.

[0020] The control host continuously monitors the data of each sensor and the working status of each component. Once a sensor failure, motor abnormality or communication interruption is found, detailed fault information will be immediately displayed on the display terminal, and an alarm signal will be sent to the remote monitoring center. At the same time, emergency measures such as stopping the rotation operation and cutting off the power supply will be taken to prevent the fault from further expanding or causing a safety accident. This function improves the safety and reliability of the construction process.

[0021] The entire rotation process can be started with one button to achieve automatic control, which greatly simplifies the operation process and reduces the risk and cost of manual intervention. At the same time, automatic control improves construction efficiency and accuracy, providing a more convenient, efficient and safe solution for the construction and installation of large bridges, buildings and heavy machinery and equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figure 1 This is a system architecture diagram of the present invention. DETAILED DESCRIPTION

[0023] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit 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.

[0024] Embodiment 1, the present invention provides a technical solution: basic implementation of a one-button start rotation automatic control method: This embodiment describes in detail a basic process of a method for realizing automatic control of rotation with one-button start. First, two monitoring systems are set up to monitor key parameters in the rotation process. Then, the rotation angle is preset to 45 degrees in the control host, and the rotation angle data is obtained in real time through the angle monitoring system. When the rotation angle does not reach 45 degrees, the drive system continues to work to ensure that the rotation process proceeds smoothly.

[0025] In terms of speed control, the control host accurately controls the rotation process according to the preset rotation start speed (such as 5 degrees / minute), average speed (such as 10 degrees / minute) and maximum speed (such as 20 degrees / minute). In the first minute after the rotation starts, it runs at a speed of 5 degrees / minute to ensure a smooth start. When all data are normal, it automatically adjusts to an average speed of 10 degrees / minute. If the rotation process stops due to abnormal conditions, after restarting, the rotation speed is adjusted according to the time limit (such as half of the remaining time), but does not exceed the maximum speed of 20 degrees / minute.

[0026] Embodiment 2, based on embodiment 1, proposes pressure and stress monitoring and safety control: This embodiment focuses on the application and safety control function of the pressure and stress monitoring system. During the rotation process, the pressure monitoring system monitors the pressure under the support leg in real time and sets the pressure limit value to 2000KN in the control host. When the monitored pressure exceeds 2000KN, the drive system immediately stops working to prevent damage to the support leg or other safety accidents.

[0027] At the same time, the stress monitoring system monitors the concrete stress value under the ball joint in real time, and sets the stress limit value (such as 80% of the concrete compressive strength) in the control host. When the monitored stress value exceeds the limit value, the safety mechanism of the drive system stopping working will also be triggered. It is worth noting that the pressure and stress monitoring are not controlled by the control host. When any monitoring value exceeds the limit value, the oil pump drive motor will be stopped independently to ensure the safety of the rotation process.

[0028] Embodiment 3, based on embodiment 2, proposes automatic deviation correction and speed adaptive control: This embodiment describes the automatic deviation correction and speed adaptive control functions in detail. During the rotation process, based on the rotation angle information fed back by the angle sensor, the control host calculates the deviation between the actual rotation angle and the preset target angle (such as 45 degrees) in real time. When the deviation exceeds the allowable range (such as ±1 degree), the control host automatically adjusts the direction and speed of the drive motor to realize the automatic deviation correction function and ensure accurate control of the rotation angle.

[0029] In addition, the speed adaptive control function controls the host to automatically adjust the output power of the drive motor according to the speed data collected by the speed sensor and the load changes during the rotation process (such as the support foot pressure, ball joint stress, etc.). For example, at the beginning of the rotation or when the load is large, the host increases the output power to provide greater torque; when the load is stable during the rotation process, the output power is reduced to maintain a stable speed. This speed adaptive control function makes the rotation process smoother and more efficient.

[0030] Embodiment 4, based on embodiment 3, proposes the realization of fault diagnosis and alarm function: This embodiment focuses on the implementation of fault diagnosis and alarm functions. During the rotation process, the control host continuously monitors the data of each sensor and the working status of each component. When a sensor failure (such as angle sensor, pressure sensor, etc.), motor abnormality (such as overheating, overload, etc.) or communication interruption is detected, the control host immediately displays detailed fault information on the display terminal and sends an alarm signal to the remote monitoring center.

[0031] At the same time, the control host will also take emergency measures, such as stopping the rotation operation, cutting off the power supply, etc., to prevent the fault from further expanding or causing a safety accident. This fault diagnosis and alarm function enables operators to discover and handle fault problems in a timely manner, ensuring the smooth progress of the rotation process and the safe operation of the equipment.
