Description

Technical Field

[0001] The present invention relates to the technical field of quality detection, and in particular to a quality detection method and a detection system for electromechanical equipment. Background Art

[0002] With the continuous exploitation of marine resources, the demand for underwater electromechanical equipment is growing. If there are quality problems with underwater electromechanical equipment, it will cause short circuits, corrosion of internal components and other faults during underwater operations, affecting the normal operation of the equipment. Quality inspection can discover such potential hidden dangers in advance, ensuring that the equipment can operate stably and reliably in the complex underwater environment and perform its due functions.

[0003] At present, most of the detection methods for underwater electromechanical equipment are mainly focused on the detection of the basic performance and safety indicators of the equipment. For some special performance indicators, such as the durability of the equipment in complex underwater environments, anti-interference ability, and long-term operation stability, the standards are not perfect. This may lead to some potential quality problems being ignored during the detection process, reducing the actual use effect and safety of the equipment, increasing the loss rate, and thus increasing costs.

[0004] At present, some testing equipment does not take into account the impact of underwater depth on the overall analysis of electromechanical equipment during the testing process of electromechanical equipment, and does not conduct a joint analysis of the quality inspection of equipment, movement and work of electromechanical equipment at various depths, which affects the accuracy and reliability of the test results. Summary of the invention

[0005] In view of the above-mentioned technical deficiencies, the object of the present invention is to provide a quality inspection method and inspection system for electromechanical equipment.

[0006] To solve the above technical problems, the present invention adopts the following technical solutions: The present invention provides a quality inspection method for electromechanical equipment, comprising the following steps: Step 1, underwater equipment data collection: performing underwater simulation tests on underwater equipment to collect equipment quality data, movement quality data and working quality data of the underwater equipment.

[0007] Step 2. Underwater equipment data analysis: After the underwater equipment data is collected, the equipment quality data of the underwater equipment is analyzed based on the equipment quality model to obtain the equipment quality evaluation index of the underwater equipment and the equipment quality grade corresponding to each depth; based on the mobile quality model, the mobile quality data of the underwater equipment is analyzed to obtain the mobile quality evaluation index of the underwater equipment and the mobile quality grade corresponding to each depth; based on the working quality model, the working quality data of the underwater equipment is analyzed to obtain the working quality evaluation index of the underwater equipment and the working quality grade corresponding to each depth.

[0008] Step 3. Equipment depth quality analysis: Analyze the equipment quality level, movement quality level and working quality level of the underwater equipment at each depth, so as to set the working depth range of the underwater equipment. Based on this, analyze the equipment quality assessment index, movement quality assessment index, working quality assessment index and working depth range of the underwater equipment based on the equipment early warning model, so as to issue an early warning.

[0009] Preferably, the specific setting process of setting the working depth range of the underwater equipment is as follows: weighted calculation is performed on the equipment quality level, movement quality level and working quality level corresponding to each depth of the underwater equipment according to each depth to obtain the quality level of the underwater equipment at each depth.

[0010] The minimum quality grade and maximum quality grade of standard underwater equipment in the database are recorded as the lower limit and upper limit of the standard quality grade range. If the quality grade of the underwater equipment at a certain depth belongs to the standard quality grade range, and the equipment quality grade at this depth is greater than the preset standard equipment quality grade, the mobile quality grade is greater than the preset standard mobile quality grade, and the working quality grade is greater than the preset standard working quality grade, it indicates that the depth range of the depth is the effective working depth range of the underwater equipment, thereby obtaining the effective depth ranges of the underwater equipment, and summarizing the effective depth ranges of the underwater equipment to obtain the working depth range of the underwater equipment.

[0011] Preferably, the early warning is carried out, and the specific early warning process is as follows: the equipment quality assessment index, mobile quality assessment index, working quality assessment index and working depth range of the underwater equipment are substituted into the quality assessment index calculation formula to obtain the quality assessment index of the underwater equipment; according to the analysis process of a single underwater equipment, each underwater equipment of each experimental batch is analyzed to obtain the quality assessment index of each underwater equipment of each experimental batch; the minimum quality assessment index and the maximum quality assessment index of each underwater equipment of each quality grade in the database are respectively recorded as the lower limit and the upper limit of the standard quality assessment index interval of the underwater equipment of each quality grade, so as to obtain the standard quality assessment index interval corresponding to each quality grade of the underwater equipment; if the quality assessment index of an underwater equipment of a certain experimental batch belongs to the standard quality assessment index interval of a certain quality grade, then the underwater equipment of the experimental batch is of the quality grade, so as to obtain the quality grade of each underwater equipment of each experimental batch.

[0012] The underwater equipment of each experimental batch is counted according to each quality grade to obtain the number of underwater equipment corresponding to each quality grade of each experimental batch. If the number of underwater equipment of a certain quality grade of a certain experimental batch is greater than the corresponding preset standard number, it indicates that the production batch corresponding to the experimental batch is unqualified and an alarm is issued.

[0013] On the other hand, the present invention provides a quality inspection system for electromechanical equipment, comprising the following modules: an underwater equipment data acquisition module, used to perform underwater simulation tests on underwater equipment, and collect equipment quality data, movement quality data and working quality level of the underwater equipment.

[0017] 2. On the one hand, the present invention sets up an electromechanical equipment detection environment at different depths to obtain quality data of the electromechanical equipment at different depths, thereby reducing the situation where the underwater electromechanical equipment does not meet the quality requirements at a specific underwater depth and increasing the validity of the data.
