Abstract
Description
Technical Field
[0001] This invention relates to the field of skid-mounted equipment operating condition control technology, specifically to a skid-mounted enclosure operating condition control method and system. Background Technology
[0002] A compressor is a compressor unit that integrates the compressor host, motor, buffer, heat exchanger and other equipment on a movable common base. It has the advantages of easy installation, easy relocation and compact design, and is widely used in petrochemical industry, ship equipment, offshore platform and other fields.
[0003] In actual compressor operation, to meet environmental protection and operator health requirements, a skid-mounted enclosure is typically installed outside the compressor to reduce noise propagating outwards during operation. However, when the compressor operates within the skid-mounted enclosure, it faces various interference factors, specifically: the compressor load may fluctuate due to changes in process requirements; the internal temperature of the enclosure may fluctuate due to changes in ambient temperature and equipment heat dissipation; and the compressor's vibration frequency may shift due to equipment wear, changes in operating conditions, and other factors. These interference factors can affect the noise reduction effect of the skid-mounted enclosure.
[0004] Existing compressor noise reduction solutions typically employ passive noise reduction measures with fixed parameters, such as setting up sound-absorbing panels and silencers. These measures cannot adaptively adjust to changes in operating conditions and are prone to noise reduction failure when interference factors such as load, temperature, and vibration frequency change.
[0005] Therefore, there is an urgent need for a method and system that can adaptively adjust the noise reduction control strategy according to the changes in the working conditions of the skid-mounted enclosure, so as to achieve stable noise reduction and controllable energy consumption. Summary of the Invention
[0006] The purpose of this invention is to provide a method and system for controlling the operating conditions of a skid-mounted housing. The technical problem to be solved is that existing compressor noise reduction schemes cannot adaptively adjust according to changes in operating conditions, resulting in noise reduction failure.
[0007] This invention is achieved through the following technical solution:

[0014] Furthermore, based on the above operating parameters, the current operating status of the skid-mounted enclosure is determined, including the following steps:
[0015] Compare the above operating condition parameters for each type with the preset threshold ranges for the corresponding types;
[0016] When any of the above operating parameters exceeds the corresponding threshold range, the current operating condition is determined to be an interference condition.
[0017] Based on the types of operating parameters that exceed the above threshold range, determine the type of interference condition.
[0018] Furthermore, based on the aforementioned types of interference conditions, the corresponding adaptation adjustment strategy is determined, including the following steps:
[0019] When the above-mentioned disturbance condition is a load change state, the above-mentioned adaptability adjustment strategy is to adjust the speed and / or discharge pressure of the above-mentioned compressor according to the load change.

[0021] When the above-mentioned interference condition is a vibration frequency offset state, the above-mentioned adaptation adjustment strategy is to adjust the control parameters of the active noise reduction device and / or the operating frequency of the compressor according to the vibration frequency offset.
[0022] Furthermore, the aforementioned noise reduction adjustment strategy includes at least one of the following:

[0024] Adjust the layout range of the sound-absorbing panel assembly installed in the aforementioned skid-mounted enclosure;
[0025] Adjust the installation damping parameters of the compressor mentioned above.
[0026] Furthermore, this operating condition control method also includes the following steps:
[0027] Obtain the feedback operating parameters of the skid-mounted housing after the noise reduction actuator performs the noise reduction operation;
[0028] Based on the above feedback operating parameters, the adjusted control parameters are corrected to generate corrected control parameters.
[0029] Based on the revised control parameters, the noise reduction actuator is controlled to perform noise reduction operations.
[0030] The second aspect provides a skid-mounted housing-based operating condition control system, wherein a compressor is installed within the skid-mounted housing, including:
[0031] The parameter acquisition module is used to acquire the operating parameters inside the skid-mounted enclosure; the types of operating parameters include load parameters, temperature parameters, and vibration frequency parameters.
[0032] The working condition identification module is connected to the parameter acquisition module.

[0036] Compared with the prior art, the present invention has the following advantages and beneficial effects:
[0037] By utilizing load parameters, temperature parameters, and vibration frequency parameters, a comprehensive perception of the energy, thermodynamic, and dynamic states of the skid-mounted enclosure is achieved, overcoming the limitation of single-parameter monitoring in identifying complex interferences. Based on this, the collected parameters are abstracted into specific interference condition types, quickly locating the interference source and avoiding blind adjustments. The aforementioned adaptive adjustment strategy simultaneously covers both compressor operating parameter adjustments and noise reduction execution strategy adjustments, synergistically changing noise levels; simultaneously, it optimizes the suppression effect of the noise reduction actuator along the propagation path, with the synergy of both being superior to single-path adjustments. Addressing the noise reduction failure problem caused by load fluctuations, temperature drift, and vibration frequency shifts within the skid-mounted enclosure, this application dynamically follows changes in interference factors to ensure that the skid-mounted enclosure maintains a superior noise reduction level across the entire operating range.

[0044] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.
[0045] First embodiment:
[0046] A method for controlling the operating conditions of a skid-mounted enclosure, which can be executed by an operating condition control system integrated into the skid-mounted enclosure. Figure 1 As shown, the operating condition control method includes the following steps:
[0047] Step S101: Obtain the operating parameters inside the skid-mounted housing.
[0048] The aforementioned skid-mounted enclosure houses a compressor. During compressor operation, various sensors installed within the skid-mounted enclosure collect operating parameters. These parameters include load parameters, temperature parameters, and vibration frequency parameters.
[0049] The above load parameters characterize the current working load of the compressor, and can be indirectly reflected by the compressor's motor current, speed, and discharge pressure. The above temperature parameters characterize the thermal environment within the skid-mounted enclosure, and can be collected by temperature sensors installed at multiple locations within the enclosure. The above vibration frequency parameters characterize the vibration characteristics of the compressor and the skid-mounted enclosure, and can be collected by vibration sensors installed on the compressor housing or the skid-mounted enclosure structure.
[0050] In addition to the parameters mentioned above, operating parameters may also include compressor speed, compressor discharge pressure, noise spectrum within the skid-mounted enclosure, and vibration amplitude of the skid-mounted enclosure, in order to more comprehensively reflect the working status of the skid-mounted enclosure.
[0051] Step S102: Determine the current operating status of the skid-mounted enclosure based on the above operating parameters.
[0052] The collected operating parameters are compared with the corresponding threshold ranges to determine whether the current operating condition is within the normal range. The threshold ranges can be customized according to actual conditions. The current operating condition includes at least one of the following: load change, temperature fluctuation, and vibration frequency deviation.
[0053] Specifically, when the load parameter exceeds the preset load threshold range, the above-mentioned interference condition type is the load change state; when the temperature parameter exceeds the preset temperature threshold range, the above-mentioned interference condition type is the temperature fluctuation state; when the vibration frequency parameter exceeds the preset frequency threshold range, the above-mentioned interference condition type is the vibration frequency deviation state.
[0054] If all the above operating parameters are within their respective threshold ranges, the current operating condition is determined to be a normal operating condition, and the current noise reduction control parameters remain unchanged.
[0055] Step S103: When the current operating condition is a disturbance condition, determine the corresponding adaptability adjustment strategy according to the disturbance condition type.
[0056] The aforementioned disturbance conditions refer to any one or more combinations of load variation, temperature fluctuation, or vibration frequency deviation. Adaptability adjustment strategies include compressor operating parameter adjustment strategies and noise reduction execution strategy adjustment strategies.
[0057] Different types of interference conditions correspond to different adaptation adjustment strategies, as detailed below:
[0058] When the disturbance condition is a load change state, the adaptation adjustment strategy is to adjust the compressor speed and / or discharge pressure according to the load change. When the load increases, the compressor noise spectrum and amplitude may change. At this time, the noise characteristics can be changed in a direction that is conducive to noise reduction by adjusting the compressor operating parameters, and the noise reduction strategy can be adjusted to adapt to the new noise characteristics.
[0059] When the disturbance condition is a temperature fluctuation state, the adaptation adjustment strategy is to adjust the ventilation and heat dissipation parameters of the skid-mounted enclosure and / or the operating parameters of the compressor according to the temperature deviation value. Increased temperature affects the sound absorption performance of noise reduction materials and may also change the operating characteristics of the compressor; therefore, comprehensive adjustments are required.
[0060] When the interference condition is a vibration frequency offset state, the adaptation adjustment strategy is to adjust the control parameters of the active noise reduction device and / or the operating frequency of the compressor according to the vibration frequency offset. Since passive noise reduction is usually designed for a specific frequency band, vibration frequency offset will cause passive noise reduction measures to fail; the active noise reduction device needs to adjust the output anti-phase acoustic wave parameters according to the change in vibration frequency.
[0061] The noise reduction adjustment strategy specifically includes: adjusting the frequency and amplitude of the anti-phase sound wave output by the active noise reduction device to match the spectral characteristics of the current compressor noise; adjusting the layout range of the sound-absorbing panel assembly set in the skid-mounted enclosure, such as adjusting the sound-absorbing structure parameters of the sound-absorbing panel; and adjusting the installation damping parameters of the compressor to change the vibration transmission characteristics.
[0062] Step S104: Generate the adjusted control parameters according to the above adaptation adjustment strategy.
[0063] Based on the determined adaptation strategy, adjusted control parameters are generated. These control parameters include, but are not limited to: the target compressor speed, the target discharge pressure, the output frequency and amplitude parameters of the active noise reduction device, the operating parameters of the ventilation and heat dissipation device, and the control signals of the adjustable damping mounting components.
[0064] Step S105: Based on the adjusted control parameters, control the noise reduction actuator inside the skid-mounted housing to perform noise reduction operation.
[0065] The adjusted control parameters are output to the corresponding noise reduction actuators, which include active noise reduction devices, sound-absorbing panel assemblies, and adjustable damping mounting assemblies. These noise reduction actuators adjust their operating states according to the received control parameters to achieve noise reduction effects adapted to the current operating conditions.
[0066] After collecting the operating parameters, it is determined whether each type of operating parameter exceeds the corresponding threshold range: if the load parameter is abnormal, the load adaptation adjustment strategy is executed; if the temperature parameter is abnormal, the temperature adaptation adjustment strategy is executed; if the vibration frequency parameter is abnormal, the vibration adaptation adjustment strategy is executed; if multiple parameters are abnormal at the same time, the comprehensive adaptation adjustment strategy is executed.
[0067] Second embodiment:
[0068] Based on the first embodiment, a feedback correction step was added to further improve control accuracy. For example... Figure 2 As shown, the following steps are included after step S105:
[0069] Step S106: Obtain the feedback operating parameters of the skid-mounted housing after the noise reduction actuator performs the noise reduction operation.
[0070] After noise reduction, the operating parameters inside the skid-mounted enclosure are collected again by sensors as feedback operating parameters. The feedback operating parameters include load parameters, temperature parameters, and vibration frequency parameters after noise reduction.
[0071] Step S107: Based on the above feedback operating parameters, correct the adjusted control parameters to generate corrected control parameters.
[0072] The feedback operating parameters are compared with preset threshold ranges, the deviation is calculated, and the current control parameters are corrected based on the deviation. For example, if the load parameters still exceed the load threshold range after noise reduction, the compressor speed and / or discharge pressure are further adjusted based on the load deviation; if the temperature parameters still exceed the temperature threshold range, the ventilation and heat dissipation parameters and / or compressor operating parameters are further adjusted based on the temperature deviation; if the vibration frequency parameters still exceed the frequency threshold range, the control parameters of the active noise reduction device and / or the compressor operating frequency are further adjusted based on the vibration frequency offset.
[0073] Step S108: Control the noise reduction actuator to perform noise reduction operation according to the above-mentioned modified control parameters.
[0074] The corrected control parameters are output to the noise reduction actuator to achieve closed-loop control. Through feedback correction steps, adaptive closed-loop control is formed, enabling the skid-mounted enclosure to maintain a superior noise reduction effect under different disturbance conditions.
[0075] Third embodiment:
[0076] A skid-mounted enclosure operating condition control system is provided, which is used to execute the steps in the above-described operating condition control method embodiments. For example... Figure 3 As shown, the operating condition control system includes:
[0077] Parameter acquisition module 1 is used to acquire operating parameters within the skid-mounted enclosure. Parameter acquisition module 1 may include various sensors, such as temperature sensors, vibration sensors, noise sensors, and current sensors, for acquiring load parameters, temperature parameters, vibration frequency parameters, etc.
[0078] Operating condition identification module 2 is connected to the parameter acquisition module. This module identifies the current operating condition of the skid-mounted enclosure based on operating condition parameters. Operating condition identification module 2 determines whether the operating condition is normal by comparing the operating condition parameters with corresponding threshold ranges.
[0079] Strategy determination module 3 is connected to working condition identification module 2. When the current working condition is identified as an interference condition and the type of interference condition is determined, the strategy determination module 3 determines the adaptability adjustment strategy based on the type of interference condition.
[0080] The parameter generation module 4 is connected to the strategy determination module 3. The parameter generation module 4 is used to generate adjusted control parameters according to the adaptability adjustment strategy.
[0081] The noise reduction control module 5 is connected to the parameter generation module 4 and the noise reduction actuator. The noise reduction control module 5 controls the noise reduction actuator to perform noise reduction operations according to adjusted control parameters. The noise reduction control module 5 may include a drive circuit and an output interface for transmitting control signals to each actuator.
[0082] In a specific embodiment, the operating condition control system further includes a feedback correction module 6, which is used to obtain feedback operating condition parameters after the noise reduction actuator performs noise reduction operation, and to correct the control parameters based on the feedback operating condition parameters.
[0083] The aforementioned skid-mounted enclosure houses a compressor and a noise reduction actuator. The noise reduction actuator includes an active noise reduction device, a sound-absorbing panel assembly, and an adjustable damping mounting assembly. The active noise reduction device outputs an anti-phase sound wave opposite to the compressor noise; the sound-absorbing panel assembly is located on the inner wall of the skid-mounted enclosure; the adjustable damping mounting assembly is located at the bottom of the compressor and is used to adjust vibration transmission characteristics. Each noise reduction actuator and parameter acquisition module 1 can be connected to a controller.

It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
