Description

Technical Field

[0001] The invention relates to the technical field of control and regulation systems, and in particular to an electrical component design sample system based on an intelligent model. Background Art

[0002] Electrical components refer to the basic components of various machine tool control circuits and electric traction and automatic control systems. They directly affect the reliability and economy of the latter two. At present, with the help of the development of current science and technology, the production process of electrical components is gradually being intelligentized, so that the output of electrical components is growing rapidly, which further drives economic development. The economic benefits generated show a complementary upward trend with the research and development and production of electrical components.

[0003] However, due to the popularity and coverage of intelligent electrical component production equipment, when intelligent production equipment fails, defective electrical components are often produced in large quantities. Therefore, people invest a certain amount of labor and economic costs in intelligent production equipment for the maintenance of intelligent production equipment. However, at present, defective electrical components caused by some undetected intelligent production equipment failures can only be tested by manual sampling with the help of mechanical equipment, and truly intelligent modular sample testing has not been achieved. Summary of the invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides an electrical component design sample system based on an intelligent model, which solves the technical problems raised in the above-mentioned background technology.

Through the operation of modules in the system, detection items for electrical component sample targets can be set according to various parameters of the electrical components, and the set detection items can be stored. When the subsequent electrical component sample targets need to be detected, the system can analyze the parameters of the current electrical component sample targets, so as to configure different inspection items for the electrical component sample targets to be detected with the help of the analysis results, so that the operation and use of the system tends to be modularized and can adapt to the detection and testing of all electrical component sample targets within a certain data support range.

[0041] During the operation of the system in the present invention, real-time monitoring of electrical component sample targets that are in the process of inspection can be carried out, and by further setting an early warning threshold, it is possible to determine in real time whether the electrical component sample target currently under inspection has been damaged, so that after the damage is determined, the inspection data can be collected and fed back in a timely manner, thereby achieving the purpose of improving the efficiency and accuracy of electrical component sample target inspection.

[0042] The present invention can provide a continuous inspection method for electrical component sample targets through the setting of modules in the system. The autonomous operation of the modules not only reduces the proportion of manual participation required in the inspection process, but also minimizes the specification parameter restrictions of the electrical component sample targets. In addition, the parameter characteristics of the electrical component sample targets stored in the storage unit in the system can be modified or supplemented in the same way, making the system more applicable, thereby reducing the elimination rate of the system during long-term use, ensuring that the system can serve and detect electrical component sample targets for a longer period of time.

The equipment used in the monitoring module 6 collects the status data of the electrical component sample target in real time during the operation of the test project, and triggers the braking unit 61 to operate when the status data reaches the set early warning threshold setting range.

[0079] The provision of the braking unit 61 improves the efficiency of the system in detecting the electrical component sample target.

[0081] In terms of specific implementation, based on Example 1, this example refers to Figure 1 The following is a further detailed description of an electrical component design sample system based on an intelligent model in Example 1:

[0082] After feeding back the data packet to the control terminal 1, the feedback module 7 determines whether the electrical component sample target is damaged according to the data content in the data packet, and calculates the life consumption rate of the electrical component sample target with reference to the data content in the corresponding data packet of the damaged electrical component sample target, and the formula is:

[0083] ; Where: The real-time consumption rate of the target life of the electrical component sample;

[0090] In addition, the setting of modules in the system can provide a continuous inspection method for electrical component sample targets. The autonomous operation of the modules not only reduces the proportion of manual participation required in the inspection process, but also minimizes the specification parameter restrictions of the electrical component sample targets. In addition, the parameter characteristics of the electrical component sample targets stored in the storage unit of the system can be modified or supplemented in the same way, making the system more applicable, thereby reducing the elimination rate of the system during long-term use, ensuring that the system can serve and detect electrical component sample targets for a longer period of time.
