Description

Technical Field

[0001] The invention belongs to the technical field of underwater detection equipment, and in particular relates to a test system for a platform-type underwater vehicle. Background Art

[0002] An underwater vehicle is a device specially designed for autonomous or remote navigation in water. It is widely used in fields such as ocean exploration, environmental monitoring, and military reconnaissance. Its structure usually includes core components such as a pressure hull, a propulsion system, a control system, and sensors, and can move flexibly at different depths and in complex waters. Depending on mission requirements, underwater vehicles can be equipped with various equipment, such as sonar, cameras, and environmental sensors, for seabed topography mapping, data collection, or target search. The design of the vehicle focuses on fluid dynamics to reduce underwater resistance and improve endurance. In special applications, bionic technology, foldable structures, or adaptive propulsion devices may also be integrated to improve its maneuverability and work efficiency.

[0003] When performing tasks, underwater vehicles rely on the normal operation of a variety of electronic components, including processors, power modules, communication equipment and sensors in the control system, which together ensure the navigation, data collection and real-time feedback functions of the vehicle. Therefore, before the vehicle is launched, all key electronic components must be fully tested and verified to ensure that their performance meets the expected requirements and to prevent equipment failure due to extreme conditions such as high pressure, high humidity and low temperature in the underwater environment. Common tests include circuit integrity checks, signal transmission tests, and pressure resistance and waterproof verification of components. These steps not only help improve the working reliability of the vehicle, but also extend its service life, ensuring that it can operate safely and stably in complex underwater environments.

[0004] At present, there are obvious deficiencies in the detection methods of electronic components of underwater vehicles. In particular, once a component is found to have failed in the detection process, it must be removed from the assembled vehicle, replaced, and tested again. This link exposes multiple problems. First, the operation of removing and replacing components is very time-consuming, especially when the component installation location is complex or multiple other components need to be disassembled to access the target component, which greatly prolongs the entire detection and maintenance process. Secondly, frequent disassembly and assembly operations not only increase the workload, but also easily cause physical damage to the structure and other components of the vehicle, and may even affect the sealing and reliability of the vehicle. In addition, replacement testing after component failure means that the entire test process must be restarted, which invisibly further prolongs the test cycle and increases labor and material costs. If there are multiple failed components during the test process, the process of checking and replacing them one by one will be more cumbersome and inefficient, which may cause progress delays and increase the complexity and unpredictability of the project. In general, this test mode not only reduces work efficiency, but also brings potential risks to the integrity and subsequent performance of the vehicle itself. Summary of the invention

[0005] In view of the problems existing in the prior art, the present invention provides a physical simulation platform for underwater robot functional testing, which aims to solve the problems of long testing cycles, time-consuming and labor-intensive operations, easy damage to the vehicle structure and increased costs caused by the need to remove, replace and retest components when they fail during the current detection process of underwater vehicle electronic components.

[0006] The present invention is implemented as follows: a test system for a platform-type underwater vehicle, characterized in that it includes a baseboard, a main control module, a voltage-stabilized power supply, a communication module, a posture adjustment unit, a buoyancy unit, a fuel tank, an underwater detection unit, a power unit and a display module; the baseboard forms a platform, and the main control module, the voltage-stabilized power supply, the communication module, the posture adjustment unit, the buoyancy unit, the fuel tank, the underwater detection unit, the power unit and the display module are fixedly mounted on the baseboard in a detachable manner.

[0007] The base plate is provided with N parallel T-shaped slots, and the main control module, voltage-stabilized power supply, communication module, attitude adjustment unit, buoyancy unit, oil tank, underwater detection unit, power unit and display module are installed on the base plate by bolts combined with the T-shaped slots.

[0008] In the above technical solution, preferably, the voltage-stabilized power supply is connected to the main control module and supplies power to the main control module.

[0009] In the above technical solution, preferably, the posture adjustment unit includes a retaining ring, a torsion bar, a mass block, a lead screw, a threaded sleeve, a deflection drive motor, and an axial drive motor; the torsion bar is installed between the two retaining rings, the torsion bar rotates around its own axis, the mass block is installed on the torsion bar and forms an axial linear motion pair, the deflection drive motor is connected to the torsion bar and drives the torsion bar to rotate, and the axial drive motor drives the mass block to move along the torsion bar through a telescopic assembly composed of a lead screw and a threaded sleeve. In the posture adjustment unit, the battery is replaced with an aluminum alloy mass block, eliminating the potential safety hazards caused by the use of batteries and ensuring that the test process is more environmentally friendly and safe. This improvement not only improves the safety of operation, but also reduces the potential impact on the environment, and meets modern green testing standards.

[0010] In the above technical solution, preferably, the buoyancy unit includes a gear pump, a solenoid valve, an oil pipeline, a bladder and an oil tank, and the gear pump, the solenoid valve and the oil pipeline constitute an oil delivery assembly connected between the bladder and the oil tank.

[0011] In the above technical solution, preferably, the substrate includes a bracket and a table plate, the table plate is installed on the bracket and forms the platform, and the table plate is composed of N aluminum alloy profiles arranged in parallel.

[0012] The physical simulation platform for underwater robot function testing has many significant advantages and effects.

[0013] First of all, each test unit is laid out flat on the substrate, no longer restricted by spatial position constraints, making the entire test operation more flexible and efficient. This flat design avoids the space limitation problem caused by component stacking or compact arrangement in traditional test platforms, thus providing testers with a wider operating space. Whether it is installation, debugging, or replacing components, operators can easily access each unit, avoiding complicated disassembly and assembly steps, especially when components fail, they can quickly locate and replace them. This simple operation method not only shortens the time for repair and maintenance, but also reduces the potential damage to the equipment or platform structure caused by frequent disassembly and assembly, and improves the stability and reliability of the overall test. In addition, the increase in spatial freedom also means that the test platform has higher flexibility in layout and configuration, can adapt to different types and scales of test needs, and effectively improves the scalability of the system.

[0014] Secondly, the platform can support batch testing of multiple test units at the same time, greatly improving work efficiency. The traditional testing method usually tests each component individually, while the physical simulation platform allows multiple components or system modules to be tested simultaneously on the same platform through a tiled layout, thereby significantly shortening the test cycle. This batch testing method is particularly suitable for large-scale functional testing needs, and can comprehensively evaluate the performance of multiple components in a short period of time, saving testing resources and time costs. At the same time, the results of batch testing are more consistent and comparable, which helps to discover and solve potential systemic problems, thereby improving the testing quality and efficiency of the entire underwater robot. This design makes the platform highly scalable and adaptable, suitable for a variety of application scenarios.

[0015] In addition to the aforementioned advantages and effects, the physical simulation platform for underwater robot functional testing also has the following key advantages: the platform can integrate advanced data acquisition systems to record the performance data of each test unit in real time during the test. This real-time monitoring can not only provide a detailed basis for subsequent data analysis, but also timely discover problems and make adjustments during the test, thereby improving the effectiveness and accuracy of the test. The modular design of the platform allows each test unit to be flexibly combined and configured according to specific needs. This design not only facilitates testers to customize according to different test purposes, but also improves the maintainability of the platform, facilitates the replacement and upgrading of individual modules, and extends the service life of the entire platform. By optimizing the test process and realizing batch testing, the platform significantly reduces the demand for manpower. In traditional testing methods, multiple testers are usually required to collaborate to complete various tasks, while the efficiency of the physical simulation platform enables one or a few people to complete large-scale testing, improve work efficiency, and reduce labor costs. Safety is fully considered in the design of the platform, and pressure-resistant materials and protective measures are used to ensure the safety of personnel during the test. At the same time, the use of aluminum alloy mass blocks instead of batteries eliminates potential risks such as battery leakage or explosion, ensuring that the entire test process is safer and more reliable. Since each test unit is independently arranged on the substrate, testers can easily identify the location of the faulty component and quickly perform fault diagnosis. This intuitive layout reduces the complexity of troubleshooting, shortens maintenance time, and improves system availability. The flexibility and efficiency of the platform provide convenient conditions for the research and development of new technologies and new products. The R&D team can quickly verify new design ideas and technical solutions on the platform, accelerate product iteration and optimization processes, and enhance innovation capabilities. These advantages and effects make this physical simulation platform an ideal choice for underwater robot functional testing, which can significantly improve test efficiency, reduce costs, enhance safety, and promote technological progress and development.

[0016] Therefore, this simulation platform not only improves the test efficiency and flexibility, but also improves the overall safety and environmental protection by simplifying components, replacement methods and optimizing the design of attitude adjustment units. It is suitable for promotion and application in various underwater robot functional tests. BRIEF DESCRIPTION OF THE DRAWINGS
