Description

Technical Field

[0001] This relates to the fields of automatic control and underwater environment simulation technology, specifically to trigger control for experiments combined with underwater environment simulation. Background Technology

[0002] This invention relates to the field of automatic control technology, and in particular to an automatic control system for accurately controlling test triggering conditions in water discharge tests.

[0003] Currently, in the field of underwater testing engineering, especially in the verification of new technologies, materials, or equipment, model tests are often required to verify the attitude, stress, and dynamic performance of underwater equipment upon surfacing, in order to guide subsequent design, production, and practical applications. Due to the high cost, long implementation period, and safety risks associated with these tests, laboratory-based model surfacing tests have become a widely adopted and important research method.

[0004] During model emergence testing, environmental factors such as wave characteristics (e.g., wave crests and troughs) and current velocity at the moment of model emergence directly affect the reliability and reproducibility of the test. Therefore, achieving precise test trigger control to ensure that the model meets specific wave and current conditions at the moment of emergence has become one of the core research issues in this field. Currently, there is some research accumulation in related fields both domestically and internationally. For example, patent publication number CN117667233 discloses a smart laboratory operation platform system. This system controls and operates small-scale experimental equipment through remote wireless connection, improving the automation level of small laboratory equipment. However, because it focuses more on the centralized management of small equipment, it does not involve the real-time simulation and precise collaborative trigger control of the underwater experimental environment (e.g., waves and current velocity), and is insufficient in accurately simulating the real and complex marine environment when the model emerges from the water.

[0005] Furthermore, traditional model water discharge tests typically rely on manual experience and monitoring. Staff must manually select the appropriate discharge time based on observed wave changes, resulting in complex operations, low efficiency, significant errors, and difficulty in accurately reproducing test conditions. Therefore, achieving precise instantaneous water discharge that meets specific wave and current conditions, improving the reliability and reproducibility of test data, and avoiding errors and uncertainties introduced by manual operation have become critical issues that urgently need to be addressed in current technologies.

[0006] In summary, there is an urgent need in this field for an automated control system that can combine underwater environment simulation information in real time, automatically monitor changes in waves and current velocity, and automatically and accurately control the triggering of tests according to preset working conditions, so as to solve the problems of insufficient control accuracy of test triggering time, large human operation error and low efficiency in the existing technology.

[0016] Furthermore, a preferred embodiment is provided in which the network time server provides a unified network time signal to the environmental simulation system, the underwater travel control system, and the trigger control system through a local area network, ensuring that the data uploaded by each subsystem has a unified time reference.

[0017] Furthermore, a preferred embodiment is provided in which the underwater travel control system is equipped with a position sensor and a limit protection unit, which are used to detect the model's movement position in real time and feed back the signal that the model has reached the target position to the trigger control system.

[0018] Furthermore, a preferred embodiment is provided in which the trigger control system outputs at least two trigger signals based on the delay parameters set by the central control computer and the model position signal fed back by the underwater travel control system, for controlling other external measuring devices to start acquisition and recording.

[0022] Based on the same inventive concept, the present invention also provides a computer program product, which, when executed, implements the method described.

[0023] Compared with the prior art, the advantages of the technical solution provided by the present invention are as follows:

[0024] In this invention, the central control computer adopts a fully automated operation mode. Before the experiment, it generates a configuration file based on the operating parameters set by the experimenters, and automatically loads the configuration file during the experiment, realizing automatic control and operation monitoring of the experimental process. This method avoids the errors caused by traditional manual parameter setting and operation, making the experimental parameter settings more accurate, the experimental process more stable, and significantly improving the repeatability and reliability of the experiment.

[0025] The network time server provides a standard network time signal to each subsystem via the local area network, ensuring that the data reported by each subsystem carries a unified reference timestamp.

[0026] The environmental simulation system provides matching wave and flow velocities based on preset parameters from the central control computer through flow field and wave simulation. This approach enables the experimental model to accurately simulate the real underwater environment in a laboratory setting, meeting the specific wave and current conditions required during the experimental window. Compared to existing technologies that do not integrate synchronous control of environmental factors, this invention improves the coordination and accuracy between environmental simulation and trigger control, significantly enhancing the realism and reliability of the experimental results.

[0027] The underwater travel control system is equipped with position and limit sensors and continuously reports real-time information such as movement speed and position to the central control computer. This method provides real-time feedback on the model's motion status, allowing for timely correction and adjustment of travel actions, and preventing overtravel or position errors. Compared to existing technologies that simply control travel motion but lack real-time monitoring and adjustment, this invention improves the safety and stability of travel control.

[0028] The trigger control system, based on instructions from the central control computer and feedback data from the underwater travel control system, precisely controls the timing of trigger signals, achieving a high degree of coordination between trigger control, environmental simulation, and the motion state of the underwater model. This approach ensures that the experimental model meets precise wave and current velocity conditions the moment it emerges from the water, effectively solving the problem of existing technologies being unable to accurately capture specific wave and current conditions, and significantly improving the accuracy and consistency of experimental data.

[0032] Figure 3 This is a schematic diagram of the hardware structure connection. Detailed Implementation

[0033] To make the advantages and benefits of the technical solution provided by the present invention clearer, the technical solution provided by the present invention will now be described in further detail with reference to the accompanying drawings, specifically:

[0034] Implementation Method 1: This implementation method provides a test trigger control system that combines underwater environment simulation, including a central control computer, a network time server, an environment simulation system, an underwater travel control system, and a trigger control system;

[0035] The central control computer is connected to the environmental simulation system, the underwater travel control system, and the trigger control system respectively, and is used to control the actions of each system according to preset operating parameters and receive real-time status data.

[0036] The network time server is connected to the central control computer and each subsystem, providing a unified time reference for each subsystem;

[0037] The environmental simulation system provides the target flow field and target waves according to the instructions of the central control computer.

[0038] The underwater travel control system drives the model to move precisely according to the instructions of the central control computer and provides real-time feedback on the model's position status.

[0039] The trigger control system outputs precisely timed trigger signals based on the instructions of the central control computer and the real-time position feedback signals of the underwater travel control system, so as to control the test equipment to complete the test action when the model reaches the specified position and specific environmental conditions.

[0040] The environmental simulation system includes a flow field simulation system and a wave simulation system, which are used to simulate the flow velocity environment and wave environment required for the experiment, respectively.

[0041] The central control computer connects to the environmental simulation system, underwater travel control system, and trigger control system via an RJ45 physical interface and UDP communication protocol, forming a local area network and conducting real-time data communication.

[0042] The network time server provides a unified network time signal to the environmental simulation system, underwater travel control system, and trigger control system via a local area network, ensuring that the data uploaded by each subsystem has a unified time reference.

[0043] The underwater travel control system is equipped with a position sensor and a limit protection unit, which are used to detect the model's movement position in real time and feed back the signal that the model has reached the target position to the trigger control system.

[0044] The trigger control system outputs at least two trigger signals based on the delay parameters set by the central control computer and the model position signal fed back by the underwater travel control system. These signals are used to control other external measuring devices to start data acquisition and recording.

[0045] A test triggering control method combining underwater environment simulation, implemented based on the aforementioned system, is used to send control commands to each subsystem step by step according to the loaded test configuration file and a set process, receive the status information and data fed back by them, complete the bidirectional transmission of electrical information signals of control commands and status information, and perform real-time judgment and triggering control in conjunction with a unified time stamp.

[0046] Implementation Method Two: This implementation method further describes the technical solution provided above in detail, specifically:

[0047] This invention provides a test triggering control system and method that combines underwater environment simulation, the specific implementation of which is as follows:

[0048] First, the central control computer loads the test condition file and process configuration file preset by the experimenters. The test condition file includes specific parameters such as test depth, wave height, flow velocity in each flow layer, and motion speed. The process configuration file defines the test process steps, subsystem instruction codes, and corresponding status query codes.

[0049] Secondly, the central control computer sends self-test commands to the environmental simulation system, underwater travel control system, and trigger control system to perform a comprehensive system self-test and obtain self-test feedback information from each system. The test can only proceed to the preparation stage if all participating subsystems pass the self-test and the system status is normal; otherwise, the central control computer will issue an alarm to the experimenters based on the feedback fault codes, prompting them to troubleshoot the fault.

[0050] Next, after the tested subsystems pass self-testing, the central control computer starts the environmental simulation system and, based on the target environmental parameters set in the operating condition file, sequentially controls the flow field simulation system and wave simulation system to maintain the system's parameter settings, gradually reaching and stabilizing the target environmental conditions required by the experiment. Simultaneously, the sensors of the environmental simulation system continuously report wave and flow velocity data to the central control computer in real time for real-time monitoring and analysis of the environmental conditions.

[0051] Subsequently, once the environmental simulation system reaches and stabilizes under the predetermined environmental conditions, the central control computer sends control commands to the underwater travel control system and the trigger control system, sets the target speed, travel distance, and trigger delay parameters, and waits for the experimenters to click the "Start" button on the computer interface.

[0052] Once the experimenters issue the start command, the central control computer, based on real-time collected environmental data and combined with the target wave period T and the underwater horizontal travel time t, c and vertical travel time t w Startup delay T a The precise calculation, in which T a ≈nT-t c -t w , where n is the minimum number of wave cycles experienced before the test window, the specific value of which is determined based on the current environmental conditions. The trigger control system, after a delay T... a Then, a start signal is sent to the underwater travel control system, which drives the underwater travel control system to start the model movement.

[0053] During the model's movement, the underwater travel control system uses its own sensors to detect the model's speed and position in real time, and continuously reports the real-time motion status information to the central control computer and the trigger control system. When the model's position sensor in the underwater model travel control system detects that the model has accurately reached the target test position, the underwater travel control system immediately sends a model arrival signal to the trigger control system.

[0054] After receiving the arrival signal from the underwater travel control system, the trigger control system accurately outputs two trigger signals according to the preset delay parameter t, triggering other external measuring devices to start acquisition and recording, thus completing the precise data acquisition of the test model at the moment of exiting the water.

[0055] Finally, the trigger control system sends feedback to the central control computer that the test has been completed. The central control computer then stops the underwater travel control system and shuts down the wave simulation system and flow field simulation system in sequence, automatically returning to the initial state and completing the entire test process.

[0056] In terms of the system:

[0057] It includes a central control computer, a network time server, an environmental simulation system, an underwater travel control system, and a trigger control system. The specific connections, coordination relationships, and functions between the modules are as follows:

[0058] The central control computer is the core control unit of the system. It forms a local area network with the environmental simulation system, underwater travel control system and trigger control system through a common RJ45 physical interface and UDP communication protocol to realize real-time data interaction and communication. The central control computer is responsible for loading the test condition parameter file and test process configuration file pre-set by the test personnel, sending instructions to each subsystem according to the configuration file, and receiving and analyzing the status information fed back by each subsystem.

[0059] The network time server is connected to the central control computer, the environmental simulation system, and the underwater travel control system via a local area network. It provides a unified network time signal to these subsystems to ensure that the data reported by each subsystem carries a unified reference timestamp, thereby achieving time synchronization between the subsystems and facilitating subsequent data combination and analysis.

[0060] The environmental simulation system consists of a flow field simulation system and a wave simulation system. It receives environmental parameter setting instructions from the central control computer, controls the flow velocity and wave height in the experiment according to the instructions, provides an underwater simulation environment consistent with the target working conditions, and feeds back environmental data to the central control computer in real time to facilitate monitoring of the real-time status of the environment.

[0061] The underwater travel control system is located at the test site and is connected to the central control computer in the control room via an Ethernet switch and a wireless bridge. The central control computer sends instructions such as target motion speed and travel control parameters to the underwater travel control system, controlling the underwater travel motor to drive the test model to move underwater according to a preset speed and trajectory. At the same time, the underwater travel control system detects real-time motion speed and position data through internal sensors and continuously feeds it back to the central control computer. In addition, it sends the real-time position signal of the model to the trigger control system, realizing precise control of the model's motion process.

[0062] The trigger control system is also located at the test site. It communicates with the central control computer in real time via an Ethernet switch and a wireless bridge, receiving trigger signal timing and delay parameters from the central control computer, and receiving model positioning signals provided by the underwater travel control system. Based on the above data and preset parameters, the trigger control system accurately outputs corresponding trigger signals to control other external measuring devices to precisely start data acquisition and recording. In addition, the trigger control system also receives timing signals from the underwater travel control system to ensure accurate correspondence between the trigger action and the model position.

[0063] Through the coordinated operation of the aforementioned subsystems, this invention achieves automated control of the experimental process. The environmental simulation system provides precise underwater environmental conditions, the central control computer monitors and analyzes the operational status of each subsystem in real time, the underwater travel control system enables precise motion control of the experimental model, and the trigger control system ensures accurate triggering of the measuring equipment when the model reaches the target position. This forms a complete, highly automated experimental system combining underwater environmental simulation and experimental trigger control. The implementation of this invention effectively solves the technical problems of large human error, poor accuracy, and low experimental repeatability in existing technologies, and has significant engineering practical value.

[0066] The test triggering control system, which incorporates underwater environment simulation, features an automated operation mode for the entire test process. Before the experiment, the central control computer receives settings from the experimenters to define the test conditions, customize the test process and steps, and saves the content as a configuration file. During the experiment, the configuration file is loaded, and the central control computer automatically runs each step according to the customized content. It sends control commands to the environment simulation system, the underwater travel control system, and the triggering control system, while simultaneously receiving status information and data. It monitors and comprehensively analyzes the operating results of each system. The background system combines and analyzes the data to determine whether the underwater environment has reached the simulated state, i.e., the test window period has been reached.

[0067] The network time server provides standard clock signal synchronization for the subsystem, so that the necessary data reported to the central control computer for judging the test window period carries a timestamp. The timestamp ensures the consistency of its time base through network time synchronization, and the timestamp value can be used as the basis for background data combination processing.

[0068] The environmental simulation system consists of a flow field simulation system and a wave simulation system. It sets parameters according to the working condition settings issued by the central control computer and provides a matching flow field and wave environment during the test.

[0069] The underwater travel control system is connected to the central control computer via a wired local area network and a wireless bridge. The central control computer sets the speed and travel distance for the underwater travel control system. The underwater travel control system reports the collected and calculated underwater movement speed, position and other information to the central control computer. The sensors of the underwater travel control system provide reference position and arrival signals and perform limit protection.

[0070] The trigger control system is connected to the central control computer via a wired local area network and a wireless bridge, and receives the central control computer's setting and control of the trigger signal timing.

[0071] The test trigger control system, which combines underwater environment simulation, enables the test to monitor the operation of the underwater environment simulation system and the measurement data of waves and current velocity in real time. It automatically controls the triggering of the test based on whether the real-time environmental simulation conditions match the set operating conditions, so that the model meets the specific wave and current conditions the moment it leaves the water.

[0073] The central control computer operates in a fully automated mode, accepting settings from the experimenters before the experiment to define the test conditions and customize the test procedures and steps. The test conditions are saved as an .xlsx file, containing the condition name and parameter values. For example, parameters related to the environmental simulation system include test depth, wave height, velocity in flow layer 1, velocity in flow layer 2, and velocity in flow layer 3; parameters related to the underwater travel control system include test speed and return speed; and parameters related to the trigger control system include the delay T of other external trigger signals. other The test window includes a start delay T1 and an end delay T2, with the underwater travel control system activation as the starting point; an output delay t1 and an output delay t2 of trigger signal 1 and trigger signal 2 of the trigger control system, with the trigger control system output signal 1 as the starting point; and a test end delay T3, with the trigger control system output signal 1 as the starting point. The process step content is saved as an XML configuration file. This configuration content includes, for example, the test stage name, process step name, test subsystem ID, test subsystem automatic control identifier, test subsystem instruction code, automatic status query identifier, and test subsystem status query code. Some process step configurations also include the operating condition name and corresponding operating condition value.

[0074] Before the experiment, the central control computer loads the operating conditions and configuration files. The software interface displays the process steps through a list box. The background system encodes the instructions into corresponding UDP data packets and sends control instructions to the subsystem step by step according to the customized content. After the current step is completed, the status query code is converted into a corresponding UDP data packet and a query instruction is sent to the subsystem according to the automatic status query identifier and status query code. After waiting for the status information to return and confirm, the status bar of the list item shows that it has been completed, and the subsequent steps are performed.

[0075] During the experiment, the subsystem continuously reports status information and data to the central control computer, monitors and comprehensively analyzes the operating results of the test system; data related to the analysis and judgment of the experimental window is sent to the central control computer with a time stamp based on the network time server network time synchronization at a short interval; the background of the central control computer combines and analyzes the operating results of each subsystem to determine whether the underwater environment simulation state has reached the test window period.

[0076] The network time server provides standard clock signal synchronization for the subsystem, so that the necessary data reported to the central control computer for analyzing and judging the test window period carries a timestamp. The timestamp ensures the consistency of its time base through network time synchronization, and the timestamp value can be used as the basis for background data fusion processing.

[0077] The environmental simulation system consists of a flow field simulation system and a wave simulation system. It sets parameters according to the working condition settings issued by the central control computer and provides a matching flow field and wave environment during the test.

[0078] The underwater travel control system is connected to the central control computer via a wired local area network and a wireless bridge. The central control computer sets the speed and travel distance for the underwater travel control system. The underwater travel control system reports the collected and calculated information such as the speed and position of the underwater motion platform to the central control computer. The sensors of the underwater travel control system provide reference position and arrival signals and perform limit protection.

[0079] The trigger control system is connected to the central control computer via a wired local area network and a wireless bridge, and receives the central control computer's setting and control of the trigger signal timing. The trigger control system is also connected to the underwater travel control system, and receives timing signal control and travel signal detection from the underwater travel control system.

[0080] The test trigger control system, which combines underwater environment simulation, enables the test to monitor the operation of the underwater environment simulation system and the measurement data of waves and current velocity in real time. It automatically controls the triggering of the test based on whether the real-time environmental simulation conditions match the set operating conditions, so that the model meets the specific wave and current conditions the moment it leaves the water.

[0081] The central control computer is used to send instruction messages to each subsystem according to the test procedure and receive status data reported by each subsystem, and to monitor and analyze the operating results of the test system.

[0082] This invention provides a test triggering control method that combines underwater environment simulation, such as... Figure 2 As shown, the test trigger control system, which is applied to the underwater environment simulation as described above, is connected to the trigger control system as follows: Figure 3 The instructions include the following steps:

[0083] During the experiment, the central control computer first sends self-test commands to each underwater environment simulation subsystem. Each subsystem then reports its self-test results and system health status. Subsequent experimental operations can only proceed if all systems are functioning normally. If a system fails its self-test, the fault is resolved based on the returned fault code. Each environmental simulation system selects specific wave and current acquisition points and reports data to the central control computer for analysis and assessment of the experimental window period. When the underwater environment simulation results meet the operating conditions, the central control computer, combining historical data and the current operating condition settings, analyzes and predicts the occurrence period T of the target wave's peak or trough and the underwater horizontal travel time t. c 1. Duration of vertical underwater travel (t) w When the experimenter clicks the start button, the central control computer calculates a certain delay T based on the current environmental simulation data. a The time calculation method is T. a ≈nT-t c -t w n is the minimum number of cycles experienced before the test window, and the value of n depends on the specific wave conditions. The trigger control system then undergoes this delay T. a The system then sends a start signal to the travel control system; simultaneously, the central control computer calculates a certain delay T based on the travel control system status data. b Time T b The calculation method is T b ≈T a +t c The trigger control system after the delay T b Subsequently, other external measurements are triggered; when the travel control system detects movement to the test point, it sends an arrival signal to the trigger control system, which outputs two trigger signals based on this signal and the delays t1 and t2 in the working condition settings; after the experiment is completed, the central control computer determines the end of the experiment based on the monitoring data and automatically restores the environmental simulation system. The above experimental process is automatically completed after the process step configuration file is written into the central control computer in fully automatic mode.

[0084] This invention can monitor the operation of the underwater environment simulation system and the wave and current velocity measurement data in real time. It automatically controls the triggering of the test based on whether the real-time environmental simulation matches the set operating conditions. This control over the triggering time ensures that the model meets specific wave and current conditions the instant it emerges from the water. This results in a highly integrated, automated, and easy-to-operate test platform, solving the problems of traditional testing methods such as reliance on manual operation, large time errors, and low efficiency.
