[0001] This invention relates to the field of high-precision DC speed control technology for heavy-duty testing equipment, and particularly to a method, device, and electronic equipment for the smooth start-up of heavy-duty testing equipment. Background Technology

[0002] With the increasing demand for hypergravity environment simulation in fields such as aerospace, military training, and high-end sports training, the stability and safety of manned centrifuges, as core equipment for simulating hypergravity environments, have become key considerations. Manned centrifuges generate centripetal acceleration through high-speed rotation to simulate hypergravity environments of varying intensities, providing pilots, astronauts, or athletes with opportunities for adaptive training.

[0003] In this process, the DC speed controller, as the core component controlling the centrifuge's rotational speed, directly affects the centrifuge's start-up smoothness, operational stability, and safety protection capabilities. Traditional overweight training equipment typically uses a single acceleration curve or directly sets the target speed for start-up control, with the DC speed controller directly driving the motor to achieve the operating speed. Summary of the Invention

[0004] In view of this, the present invention provides a method, device and electronic equipment for the smooth start of a heavy-duty test equipment, the main purpose of which is to solve the problems of large impact and low safety factor of the current method of starting a heavy-duty test equipment by using a single acceleration curve or directly setting the target speed.

Based on the performance parameters and predetermined test requirements of the target overweight test equipment, the start-up acceleration phase of the target overweight test equipment is planned to obtain multi-level acceleration curves; When the detection result indicates that the input voltage is within the preset voltage range and the operating status parameters are in normal operating condition, the output voltage of the DC speed controller is adjusted using a dynamic proportional gain adjustment method based on the multi-level acceleration curve, so as to control the target overweight test equipment to perform multi-stage smooth start-up.

[0006] Optionally, the method further includes: When the detection result indicates that the input voltage is not within the preset voltage range and / or the operating status parameter is in an abnormal operating state, the target overload test equipment shall be prohibited from being started and an abnormal warning shall be issued based on the detection result.

[0007] Optionally, the step of adjusting the output voltage of the DC speed controller based on the multi-stage acceleration curve using a dynamic proportional gain adjustment method to control the target overweight test equipment to perform multi-stage smooth start-up specifically includes: The output voltage of the DC speed controller is adjusted based on the first acceleration and first duration corresponding to the first start-up acceleration stage of the multi-level acceleration curve, so as to control the target overweight test equipment to start smoothly in the first stage. The output voltage of the DC speed controller is adjusted based on the second acceleration and the second duration corresponding to the second start-up acceleration stage of the multi-level acceleration curve, so as to control the target overweight test equipment to start smoothly in the second stage. Based on the target acceleration corresponding to the third start-up acceleration stage of the multi-stage acceleration curve, the output voltage of the DC speed controller is adjusted using a dynamic proportional gain adjustment method to control the target overweight test equipment to start smoothly in the third stage. The multi-stage smooth start includes a first-stage smooth start, a second-stage smooth start, and a third-stage smooth start.

[0008] Optionally, the output voltage of the DC speed controller is adjusted based on the first acceleration and first duration corresponding to the first start-up acceleration stage of the multi-level acceleration curve to control the target overweight test equipment to perform a smooth start-up in the first stage, specifically including: Step 1: When the current operating state is detected to be the first start-up acceleration stage, the main shaft acceleration of the target overweight test equipment is accumulated according to the first acceleration and a predetermined time step to obtain the first current acceleration; Step 2: Determine whether the first current acceleration is equal to the first target acceleration, and obtain the determination result; Step 3: If the determination result is that the first current acceleration is less than the first target acceleration during the first start-up acceleration phase, repeat step 1 to update the first current acceleration. Step 4: If the judgment result is that the first current acceleration is equal to the first target acceleration in the first start-up acceleration phase, control the main shaft acceleration of the target overweight test equipment at the first target acceleration until the first duration is reached, so as to control the target overweight test equipment to start smoothly in the first phase.

[0009] Optionally, the second acceleration and second duration corresponding to the second start-up acceleration phase of the multi-stage acceleration curve adjust the output voltage of the DC speed controller to control the target overweight test equipment to perform a smooth start-up in the second stage, specifically including: Step 1: When the current operating state is detected to be the second start-up acceleration stage, the main shaft acceleration of the target overweight test equipment is accumulated according to the second acceleration and a predetermined time step to obtain the second current acceleration; Step 2: Determine whether the second current acceleration is equal to the second target acceleration, and obtain the determination result; Step 3: If the determination result is that the second current acceleration is less than the second target acceleration during the second start-up acceleration phase, repeat step 1 to update the second current acceleration.

[0010] Optionally, the target acceleration corresponding to the third start-up acceleration stage based on the multi-stage acceleration curve is adjusted by using a dynamic proportional gain regulation method to regulate the output voltage of the DC speed controller, so as to control the target overweight test equipment to perform a smooth start-up in the third stage, specifically including: Obtain the real-time rotational speed of the target overload test equipment; When the real-time rotational speed is less than the preset rotational speed threshold, the proportional gain of the DC speed controller that adjusts the speed of the target overload test equipment is updated to the first proportional gain in order to improve the real-time rotational speed. When the real-time rotational speed is greater than the preset rotational speed threshold, the proportional gain of the DC speed controller used to adjust the speed of the target overload test equipment is updated to the second proportional gain in order to reduce the real-time rotational speed.

[0011] Optionally, during the process of controlling the target overweight test equipment to perform a multi-stage smooth start-up, the real-time acceleration of the target overweight test equipment at the current moment is obtained; The acceleration difference is obtained by subtracting the real-time acceleration from the planned acceleration of the multi-level acceleration curve at the current moment. When the absolute value of the acceleration difference is greater than or equal to a preset difference threshold, the output voltage of the DC speed controller used to adjust the speed of the target overweight test equipment is adjusted to control the real-time acceleration of the target overweight test equipment to change according to the multi-level acceleration curve.

[0012] Optionally, after adjusting the output voltage of the DC speed controller using a dynamic proportional gain adjustment method based on the multi-stage acceleration curve to control the target overload test equipment to perform a multi-stage smooth start-up, the method further includes: When the real-time rotational speed of the target overweight test equipment is equal to the set rotational speed and the real-time acceleration of the target overweight test equipment is stable within the set range, it is determined that the target overweight test equipment has completed startup and entered normal operation mode.

[0013] To address the aforementioned problems, this application provides a smooth start-up device for overweight testing equipment, comprising: The detection module is used to detect the input voltage of the DC speed controller used to adjust the speed of the target overload test equipment and the operating status parameters of the target overload test equipment in response to the start operation of the target overload test equipment, and to obtain the detection results; The planning module is used to plan the start-up acceleration phase of the target overweight test equipment according to the performance parameters and predetermined test requirements of the target overweight test equipment, and obtain multi-level acceleration curves.

[0025] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0026] This application provides a method for the smooth start-up of an overload testing device, such as... Figure 1 As shown, it includes: Step S101: In response to the start-up operation of the target overload test equipment, the input voltage of the DC speed controller used to adjust the speed of the target overload test equipment and the operating status parameters of the target overload test equipment are detected, and the detection results are obtained; In the specific implementation process of this step, before starting the target overweight test equipment, the input voltage of the DC speed controller is detected by the voltage monitoring module to ensure that the voltage is within the normal range. At the same time, the operating status parameters of the target overweight test equipment are detected, including parameters such as current and speed, to ensure that the equipment is in normal condition.

[0027] Step S102: Based on the performance parameters and predetermined test requirements of the target overweight test equipment, plan the start-up acceleration phase of the target overweight test equipment to obtain a multi-level acceleration curve; In this step, the performance parameters of the target overweight test equipment include maximum power parameters, rated current, etc.; the predetermined test requirements can be manned test requirements, etc.; based on the performance parameters and predetermined test requirements of the target overweight test equipment, the starting acceleration phase of the target overweight test equipment is divided into multiple acceleration phases. The multiple acceleration phases include a first starting acceleration phase, a second starting acceleration phase, and a third starting acceleration phase. Acceleration and duration are configured for each of the multiple acceleration phases to obtain a multi-level acceleration curve; the first starting acceleration phase is the first acceleration, with a duration of the first duration; the second starting acceleration phase is the second acceleration, with a duration of the second duration; the third starting acceleration phase is the target acceleration, with a duration equal to the moment the target rotational speed is reached. In each phase, once the rotational speed reaches the set speed, the acceleration will remain at the set acceleration.

[0028] Step S103: When the detection result shows that the input voltage is within the preset voltage range and the operating status parameters are in normal operating condition, the output voltage of the DC speed controller is adjusted using a dynamic proportional gain adjustment method based on the multi-level acceleration curve, so as to control the target overweight test equipment to perform multi-stage smooth start-up.

[0029] In this specific implementation process, the output voltage of the DC speed controller is adjusted based on the first acceleration and first duration corresponding to the first start-up acceleration stage of the multi-level acceleration curve to control the target overweight test equipment to perform a first-stage smooth start; the output voltage of the DC speed controller is adjusted based on the second acceleration and second duration corresponding to the second start-up acceleration stage of the multi-level acceleration curve to control the target overweight test equipment to perform a second-stage smooth start; and the output voltage of the DC speed controller is adjusted using a dynamic proportional gain adjustment method based on the target acceleration corresponding to the third start-up acceleration stage of the multi-level acceleration curve to control the target overweight test equipment to perform a third-stage smooth start; wherein, the multi-stage smooth start includes the first-stage smooth start, the second-stage smooth start, and the third-stage smooth start.

[0030] This application employs a multi-stage acceleration control strategy, dividing the startup process into multiple phases for gradual acceleration. This avoids the abrupt acceleration issues common in traditional methods, minimizing the impact on trainees. A dynamic proportional gain adjustment mechanism is introduced at the acceleration phase switching points, dynamically adjusting the speed controller parameters based on the actual rotational speed. This effectively eliminates abrupt changes in control parameters during phase switching, resulting in smoother and more stable acceleration changes. A real-time monitoring and feedback adjustment closed loop is established, enabling timely adjustment of control parameters based on actual operating conditions. This adapts to different equipment operating conditions and training needs, improving the system's robustness. Through initial state detection and real-time monitoring during startup, abnormal situations can be detected promptly, allowing for protective measures to be taken, reducing the risk of equipment failure and personnel injury.

[0031] Another embodiment of this application provides a different method for the smooth start-up of an overload testing device, such as... Figure 2 As shown, it includes: Step S201: In response to the start-up operation of the target overload test equipment, the input voltage of the DC speed controller used to adjust the speed of the target overload test equipment and the operating status parameters of the target overload test equipment are detected, and the detection results are obtained; In the specific implementation process of this step, before starting the target overload test equipment, the input voltage of the DC speed controller is detected by the voltage monitoring module to ensure that the input voltage is within the normal range. At the same time, the operating status parameters of the target overload test equipment are detected, including parameters such as current and speed, to ensure that the equipment is in normal condition.

[0032] Step S202: Based on the performance parameters and predetermined test requirements of the target overweight test equipment, plan the start-up acceleration phase of the target overweight test equipment to obtain a multi-level acceleration curve; In this step, the performance parameters of the target overweight test equipment include maximum power parameters, rated current, etc.; the predetermined test requirements can be manned test requirements, etc.; based on the performance parameters and predetermined test requirements of the target overweight test equipment, the starting acceleration phase of the target overweight test equipment is divided into multiple acceleration phases. The multiple acceleration phases include a first starting acceleration phase, a second starting acceleration phase, and a third starting acceleration phase. Acceleration and duration are configured for each of the multiple acceleration phases to obtain a multi-level acceleration curve; the first starting acceleration phase is the first acceleration, with a duration of the first duration; the second starting acceleration phase is the second acceleration, with a duration of the second duration; the third starting acceleration phase is the target acceleration, with a duration equal to the moment the target rotational speed is reached. In each phase, once the rotational speed reaches the set speed, the acceleration will remain at the set acceleration. For example, for a heavy-duty testing equipment with a maximum power of 520kW, a rated current of 1080A, and a training requirement of manned testing, the first acceleration in the first start-up acceleration phase is 0.1g, lasting for 8 seconds; the second acceleration in the second start-up acceleration phase is 0.2g, lasting for 5 seconds, with control logic similar to the first start-up acceleration phase; the target acceleration in the third start-up acceleration phase is the set acceleration, and the duration is until the target speed is reached. In each phase, once the speed reaches the set speed, the acceleration will remain at the set acceleration, thus forming a multi-stage acceleration curve.

[0033] Step S203: When the detection result is that the input voltage is within the preset voltage range and the operating status parameters are in normal operating condition, the output voltage of the DC speed controller is adjusted based on the first acceleration and first duration corresponding to the first start-up acceleration stage of the multi-level acceleration curve, so as to control the target overweight test equipment to start smoothly in the first stage. This step, in its specific implementation, includes the following steps: Step S2031: When the current operating state is detected to be the first start-up acceleration stage, the spindle acceleration of the target overweight test equipment is accumulated based on the first acceleration according to a predetermined time step to obtain the first current acceleration; the spindle acceleration gradually increases. Each accumulation step is a fixed step size, and the first acceleration can be 0.1g. The current operating state is determined to be the first start-up acceleration stage by comparing the magnitude of the current acceleration with the first target acceleration; if the current acceleration is less than or equal to the first target acceleration, the current operating state is determined to be the first start-up acceleration stage.

[0034] Step S2032: Determine whether the first current acceleration is equal to the first target acceleration, and obtain the determination result; Step S2033: If the determination result is that the first current acceleration is less than the first target acceleration in the first start-up acceleration phase, step S2031 is repeated to update the first current acceleration.

[0035] Step S2034: If the determination result is that the first current acceleration is equal to the first target acceleration of the first start-up acceleration phase, the spindle acceleration of the target overload test equipment is controlled at the first target acceleration until the first duration is reached, so as to control the target overload test equipment to perform a smooth start-up in the first stage. In the first start-up acceleration phase, the output voltage is kept stable, and the acceleration is gradually increased to the first target acceleration. After the first target acceleration is reached, the system smoothly transitions to the second start-up acceleration phase.

[0036] Step S204: Adjust the output voltage of the DC speed controller based on the second acceleration and the second duration corresponding to the second start-up acceleration stage of the multi-level acceleration curve, so as to control the target overweight test equipment to start smoothly in the second stage. This step, in its specific implementation, includes the following steps: Step S2041: When the current operating state is detected to be the second start-up acceleration stage, the spindle acceleration of the target overweight test equipment is accumulated based on the second acceleration according to a predetermined time step to obtain the second current acceleration; the spindle acceleration is gradually increased, with a fixed step size each time, and the second acceleration can be 0.2g. The current operating state can be determined to be the second start-up acceleration stage by comparing the current acceleration with the first target acceleration and the second target acceleration; if the current acceleration is greater than the first target acceleration and less than or equal to the second target acceleration, the current operating state is determined to be the second start-up acceleration stage.

[0037] Step S2042: Determine whether the second current acceleration is equal to the second target acceleration, and obtain the determination result; Step S2043: If the determination result is that the second current acceleration is less than the second target acceleration in the second start-up acceleration phase, step S2041 is repeated to update the second current acceleration.

[0038] Step S2044: If the determination result is that the second current acceleration is equal to the second target acceleration of the second start-up acceleration phase, the spindle acceleration of the target overload test equipment is controlled at the second target acceleration until the second duration is reached, so as to control the target overload test equipment to perform a smooth start-up in the second stage. In the second start-up acceleration phase, the output voltage is kept stable, and the acceleration is gradually increased to the second target acceleration. After the second target acceleration is reached, the system smoothly transitions to the third start-up acceleration phase.

[0039] Step S205: Based on the target acceleration corresponding to the third start-up acceleration stage of the multi-stage acceleration curve, the output voltage of the DC speed controller is adjusted using a dynamic proportional gain adjustment method to control the target overweight test equipment to start smoothly in the third stage. In the specific implementation process, this step involves obtaining the real-time rotational speed of the target overweight test equipment; When the real-time rotational speed is less than a preset speed threshold, the proportional gain of the DC speed controller used to adjust the speed of the target overload test equipment is updated to a first proportional gain K1 to increase the real-time rotational speed; when the real-time rotational speed is greater than the preset speed threshold, the proportional gain of the DC speed controller used to adjust the speed of the target overload test equipment is updated to a second proportional gain K2 to decrease the real-time rotational speed. The speed threshold can be 5g, and can be set according to actual needs. The values ​​of the first proportional gain K1 and the second proportional gain K2 can be set according to actual needs.

[0040] Step S206: When the detection result indicates that the input voltage is not within the preset voltage range and / or the operating status parameter is in an abnormal operating state, the target overload test equipment shall be prohibited from being started and an abnormal warning shall be issued based on the detection result; In the specific implementation of this step, when the detection result indicates that the input voltage is not within the preset voltage range and / or the operating status parameter is in an abnormal operating state, the target overweight test equipment shall be prohibited from being started and an abnormal warning shall be issued based on the detection result.

[0041] Step S207: When the real-time rotational speed of the target overweight test equipment is equal to the set rotational speed and the real-time acceleration of the target overweight test equipment is stable within the set range, it is determined that the target overweight test equipment has completed the start-up and entered the normal operation mode.

[0042] In this step, when the real-time rotational speed of the target overload test equipment equals the set rotational speed and the real-time acceleration of the target overload test equipment stabilizes within the set range, the target overload test equipment is considered to have completed startup and entered normal operation mode. The set range can be set according to actual needs.

[0043] This application employs a multi-stage acceleration control strategy, dividing the startup process into multiple phases for gradual acceleration. This avoids the abrupt acceleration issues common in traditional methods, minimizing the impact on trainees. A dynamic proportional gain adjustment mechanism is introduced at the acceleration phase switching points, dynamically adjusting the speed controller parameters based on the actual rotational speed. This effectively eliminates abrupt changes in control parameters during phase switching, resulting in smoother and more stable acceleration changes. A real-time monitoring and feedback adjustment closed loop is established, enabling timely adjustment of control parameters based on actual operating conditions. This adapts to different equipment operating conditions and training needs, improving the system's robustness. Through initial state detection and real-time monitoring during startup, abnormal situations can be detected promptly, allowing for protective measures to be taken, reducing the risk of equipment failure and personnel injury.

[0048] In the specific implementation process, the start-up control module 303 is also used to adjust the output voltage of the DC speed controller according to the second acceleration and the second duration corresponding to the second start-up acceleration stage of the multi-level acceleration curve, so as to control the target overload test equipment to perform a smooth start-up in the second stage.

The internal memory provides an environment for the operation of the operating system and computer programs in the non-volatile storage medium.

When the program of the electronic device is executed by the processor, it implements the functions or steps of a client-side method for a smooth start-up of an overload test device.

[0056] Another embodiment of this application provides an electronic device, including at least a memory and a processor. The memory stores a computer program, and the processor, when executing the computer program in the memory, performs the following method steps: Step 1: In response to the start-up operation of the target overload test equipment, the input voltage of the DC speed controller used to adjust the speed of the target overload test equipment and the operating status parameters of the target overload test equipment are detected, and the detection results are obtained. Step 2: Based on the performance parameters and predetermined test requirements of the target overweight test equipment, plan the start-up acceleration phase of the target overweight test equipment to obtain multi-level acceleration curves; Step 3: When the detection result shows that the input voltage is within the preset voltage range and the operating status parameters are in normal operating condition, the output voltage of the DC speed controller is adjusted using a dynamic proportional gain adjustment method based on the multi-level acceleration curve, so as to control the target overweight test equipment to perform multi-stage smooth start-up.

[0058] This application employs a multi-stage acceleration control strategy, dividing the startup process into multiple phases for gradual acceleration. This avoids the abrupt acceleration issues common in traditional methods, minimizing the impact on trainees. A dynamic proportional gain adjustment mechanism is introduced at the acceleration phase switching points, dynamically adjusting the speed controller parameters based on the actual rotational speed. This effectively eliminates abrupt changes in control parameters during phase switching, resulting in smoother and more stable acceleration changes. A real-time monitoring and feedback adjustment closed loop is established, enabling timely adjustment of control parameters based on actual operating conditions. This adapts to different equipment operating conditions and training needs, improving the system's robustness. Through initial state detection and real-time monitoring during startup, abnormal situations can be detected promptly, allowing for protective measures to be taken, reducing the risk of equipment failure and personnel injury.
