Description

Technical Field

[0001] This application relates to the field of shipbuilding technology, and more specifically, to a control system and method for ship testing equipment. Background Technology

[0002] During the shipbuilding process, after the installation of various ship testing equipment is completed, it is necessary to inspect the integrity, correctness and reliability of the equipment installation, and verify whether its performance indicators meet the design requirements.

[0003] Due to the wide variety of equipment and systems on board and their significant differences in purpose, there are great differences between different test items, making it impossible to form a unified standard operating procedure for testing.

[0004] Especially when conducting overheating and overload tests under extreme conditions on testing equipment, the operation process is highly dependent on the operator's on-site experience and judgment. This operation method, which relies on manual experience, carries significant risks. Even a slight mistake can damage the equipment, leading to delays in the project or, in severe cases, safety accidents.

[0005] In summary, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Summary of the Invention

[0007] Firstly, a control system for a ship testing equipment is provided, comprising:

[0008] The high-voltage control module is used to control the ship's testing equipment.

[0009] The low-voltage control module is used to control the test auxiliary equipment and to convert the low-voltage signals of the test auxiliary equipment into digital signals and output them.

[0010] The instruction storage module is used to store the instructions corresponding to the preset test information.

[0011] An instruction execution module is used to control the high-voltage control module or the low-voltage control module according to the instructions in the instruction storage module.

[0012] The monitoring module collects feedback information from the ship testing equipment or testing auxiliary equipment in real time, including monitoring the status and environmental information of the ship testing equipment or testing auxiliary equipment, and transmits the feedback information to the low-voltage control module or the high-voltage control module to control the ship testing equipment or testing auxiliary equipment.

[0013] In one feasible approach, the high-voltage control module controls the ship testing equipment by at least: starting the ship testing equipment, stopping the ship testing equipment, rotating the motor forward, rotating the motor in reverse, and switching the power of the heater.

[0015] In one feasible approach, the monitoring module preprocesses the collected status and environmental information of the ship test equipment or test auxiliary equipment and then transmits it to the low-voltage control module or the high-voltage control module.

[0016] In one feasible approach, the preprocessing includes at least signal amplification and filtering.

[0017] In one feasible approach, the monitoring module presets limit values ​​corresponding to different tests. The monitoring module compares the feedback information from the ship testing equipment or test auxiliary equipment with the limit values. When the real-time feedback information is greater than the corresponding limit value, the monitoring module controls the ship testing equipment to stop operating.

[0018] In one feasible embodiment, the control system further includes an investigation module. When the interfaces of the ship testing equipment or the testing auxiliary equipment are not standardized, the investigation module is used to investigate the control information corresponding to each point on the control circuit and process the control information so that the high-voltage control module or the low-voltage control module can control the ship testing equipment or the testing auxiliary equipment.

[0019] In one feasible embodiment, the control system further includes an instruction translation module: the instruction translation module is configured with machine language corresponding to different tests, and the machine language is transmitted to the instruction execution module to execute the corresponding test information.

[0020] In one feasible approach, when the current ship testing equipment or auxiliary testing equipment has no preset instructions, the instruction translation module sets the machine language corresponding to the test, and the machine language is sent to the instruction execution module to execute the corresponding test program.

[0021] According to a second aspect of this application, a method for controlling ship testing equipment is also provided, using the ship testing equipment control system provided in the first aspect, comprising the following steps:

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0033] Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0034] According to the first aspect of this application, see Figure 1 Firstly, a control system for a ship testing equipment is provided, comprising:

[0035] The high-voltage control module is used to control the ship's testing equipment after receiving instructions.

[0036] It should be noted that controlling the ship testing equipment includes at least: starting the ship testing equipment, stopping the ship testing equipment, rotating the motor forward, rotating the motor in reverse, controlling the motor speed, and switching the power of the heater.

[0037] The low-voltage control module is used to control the test auxiliary equipment, collect the low-voltage signals of the test auxiliary equipment, convert the low-voltage signals into digital signals, and adjust the test auxiliary equipment in real time based on the digital signals.

[0038] It should be noted that the experimental auxiliary equipment includes at least external sensors, such as temperature sensors, pressure sensors, and current sensors.

[0039] It should be noted that the low-voltage control module can receive signals from buttons, sensors, or command execution modules to drive and control the test auxiliary equipment.

[0040] The instruction storage module is used to store the instructions corresponding to the preset test information.

[0041] It should be noted that the test information in the instruction storage module is set based on the operation manual corresponding to the test project, and the test information includes at least the running program, test parameters and configuration information corresponding to the test.

[0042] The instruction execution module is used to control the high-voltage control module or the low-voltage control module according to the instructions in the instruction storage module, so as to control the ship test equipment or test auxiliary equipment.

[0043] The monitoring module collects feedback information from the ship's testing equipment or auxiliary equipment in real time, including monitoring the status and environmental information of the ship's testing equipment or auxiliary equipment, and transmits the feedback information to the low-voltage control module or the high-voltage control module to control the ship's testing equipment or auxiliary equipment.

[0044] In one feasible approach, the monitoring module preprocesses the collected status and environmental information of the ship test equipment or test auxiliary equipment and then transmits it to the low-voltage control module or the high-voltage control module.

[0045] It should be noted that the preprocessing includes at least signal amplification and filtering.

[0046] In one feasible approach, the monitoring module presets limit values ​​corresponding to different tests. The monitoring module compares the feedback information from the ship testing equipment or test auxiliary equipment with the limit values. When the real-time feedback information is greater than the corresponding limit value, the monitoring module controls the ship testing equipment to stop operating.

[0047] Specifically, the instruction execution module controls the high-voltage control module to stop the ship test equipment.

[0048] In one feasible embodiment, the control system further includes an investigation module. When the interfaces of the ship test equipment or test auxiliary equipment are not uniform, the investigation module is used to investigate the power supply and control points of the main components in the control circuits of different equipment, obtain the control information corresponding to each control point, and process the control information so that the high-voltage control module or the low-voltage control module can control the ship test equipment or test auxiliary equipment.

[0049] In one feasible embodiment, the control system further includes an instruction translation module, which is configured with machine language corresponding to different tests, and transmits the machine language to the instruction execution module to execute the corresponding test information.

[0050] It should be noted that when the current ship testing equipment or auxiliary testing equipment has no preset instructions, the machine language corresponding to the test is set through the instruction translation module, and the machine language is sent to the instruction execution module to execute the corresponding test program.

[0051] According to the second aspect of this application, such as Figure 2 As shown, a method for controlling ship testing equipment is also provided, using the ship testing equipment control system provided in the first aspect, comprising the following steps:

[0052] S1. Connect the ship testing equipment control system to the ship testing equipment and testing auxiliary equipment.

[0053] Specifically, in this embodiment, in step S1, before conducting an overload test on the ship testing equipment, the output voltage or output current of the ship testing equipment is first adjusted by the high-voltage control module to control the input power and keep the input power stable.

[0054] In one feasible approach, when connecting to the ship test equipment or test auxiliary equipment in step S1, at least the high-voltage circuit of the control panel, panel chip, firmware flashing interface, and serial communication interface are included.

[0055] S2. The instruction execution module executes the preset instruction corresponding to the experiment, which is retrieved from the storage module.

[0056] S3. The weak current control module and the strong current control module receive signals from the instruction execution module and drive the test auxiliary equipment and the ship test equipment to operate according to the test requirements to complete the ship equipment test.

[0057] It should be noted that during the test, the monitoring module collects feedback information from the ship test equipment or test auxiliary equipment in real time and transmits the feedback information to the low-voltage control module or the high-voltage control module to control the ship test equipment or test auxiliary equipment.

[0058] When conducting heater over-temperature protection tests using traditional methods, operators need to manually turn on the power and activate the heating function, setting the temperature to the highest level. Then, they must use insulation cotton to block the air outlet to simulate an over-temperature condition. During this process, they must continuously wait for the high-temperature alarm to trigger. Due to human error, operators need to intermittently loosen the insulation cotton to prevent excessive air pressure from damaging the air outlet. Furthermore, if the insulation alarm fails, the heater can easily overheat and be damaged, posing a significant safety risk.

[0059] When using this application to conduct heater over-temperature protection tests, the system is started and connected to the air conditioner via an open interface protocol or the control refresh interface on the main control panel, with the temperature sensor pre-placed inside the air outlet. The low-voltage control module controls the shutdown of the fan, air inlet, and air outlet to stably create an over-temperature environment. The temperature sensor in the auxiliary testing equipment is used to detect the heater temperature. A temperature threshold is set within the monitoring module, which acquires the heater's real-time temperature and compares it with the temperature threshold to determine if the heater's power is overloaded. When the system determines that the heater should issue a high-temperature alarm, the ship's high-temperature alarm is successfully triggered, and the heater over-temperature protection test is completed. The above process requires no manual intervention, effectively avoiding the risk of equipment damage and ensuring the safety and reliability of the test.

[0060] When conducting overload alarm tests on shore power boxes using traditional methods, a current transformer is connected to the shore power circuit, and a voltage megohmmeter is used to connect to the circuit. By applying voltage to one side of the transformer, an induced current is generated on the other side. The voltage is gradually increased until the induced current reaches the required overload level, and then the shore power box is allowed to issue an overload alarm. In this process, the voltage cannot be directly and precisely controlled, leading to large current errors. The induced current increases exponentially, easily damaging the equipment, and the operation carries high safety risks. Furthermore, the current value at the time of the alarm must be recorded after the test.

[0061] When conducting overload alarm tests on shore power boxes using this application, a current transformer and a current sensor are connected to the shore power circuit as auxiliary test equipment. A low-voltage control module controls one side of the current transformer to generate the required current I1, and the other side to generate an overload current I2. According to the principle of magnetic induction, I1 / I2 = N2 / N1, where N is the number of turns in the windings on both sides of the transformer. The feedback signal from the current sensor is acquired to determine if the current on the shore power circuit side has reached the nominal overload value. When the current reaches the overload value, the alarm signal of the shore power box is detected. When the alarm signal is triggered, the current value at that moment is recorded, and the test ends. Using this application for overload alarm tests on shore power boxes allows for precise current control and automatic monitoring, eliminating the errors and safety risks associated with traditional methods.

[0062] When it is determined that the current on the shore power loop side has reached an overload value, i.e., the real-time current is obtained through a current sensor and compared with the current threshold in the monitoring module. If the real-time current obtained by the current sensor is less than the current threshold, the weak current control module is controlled to further adjust the current transformer until the real-time current obtained by the current sensor equals the current threshold.

[0063] In summary, this application addresses the pain points of cumbersome operating procedures, high dependence on shipboard equipment service providers, and high hidden dangers and risks in existing production testing processes. It can also effectively improve the accuracy and reliability of shipboard equipment testing, reduce safety risks, increase testing efficiency, and save manpower and material costs.

[0064] This application standardizes the testing process, making test results more controllable and reliable. It improves testing efficiency and result consistency, reducing waiting time and repetitive labor during testing. It also lowers the economic and time costs of training test operators. When problems arise during testing, it immediately identifies the issues with the ship's testing equipment and auxiliary equipment, while ensuring that test data meets quality standards. Furthermore, it reduces accident risks, strengthens the safety of the ship's testing equipment itself, and prevents accidents to test personnel.

[0065] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
