Description

Technical Field

[0001] The present invention relates to the field of personnel training and examination, and in particular to an Internet-based teaching and examination integrated system for personnel training. Background Art

[0002] The main purpose of safety training is to strengthen and standardize the safety training of production and operation units, improve the quality of employees, prevent casualties, reduce occupational injuries; be familiar with and be able to conscientiously implement safety production guidelines, policies, laws, regulations, and national standards and industry standards; master the knowledge of safety analysis, safety decision-making, accident prediction and prevention. Its significance is mainly: 1. Improve safety production awareness. It is impossible to achieve safety production without paying attention to safety production awareness. 2. Increase safety production knowledge; With safety production awareness, you should also have rich safety production knowledge to control the safety accidents of the enterprise. 3. Reduce the occurrence of safety accidents; safety accidents are the only criterion for measuring whether an enterprise has successfully carried out safety work. Through training, the person in charge can greatly increase the attention paid to safety production, thereby reducing the occurrence of safety accidents.

[0003] The existing safety training for employees is mostly oral teaching of safety precautions. For example, when conducting safety training on a construction site, the chief engineer of the construction site usually takes the workers to the construction site to verbally explain the safety precautions during construction to the workers. Since most of the construction workers on the construction site are farmers, they may not have a high level of education, so they may have difficulty understanding the safety knowledge taught orally. In addition to verbal teaching of safety knowledge, there is also a training method of letting employees watch safety operation videos. Compared with the ordinary training method of verbal teaching of safety knowledge, watching operation safety videos can make employees understand the relevant knowledge of safe production more simply and intuitively, and deepen the employees' understanding of safe operation knowledge. However, watching videos may still make it difficult for employees to master the relevant knowledge of safe operations proficiently, and watching videos cannot determine the degree of acceptance of each employee for safety training. If the employees still have insufficient knowledge of safe operations after watching the training videos, and still do not understand certain safety knowledge, they may cause accidents during work. Summary of the invention

[0004] In view of the shortcomings of the common training technology in the prior art that cannot provide good safety training for practitioners, the present invention provides a training system based on Internet technology, which can help practitioners quickly understand the relevant knowledge of safe operation and judge the degree of acceptance of safety training for each practitioner.

Compared with the common method of adding a fixing rod at the bottom end of the curtain, the cooperation between the sliding member 1520 and the strip groove 1340 in this embodiment allows the curtain to be folded, which is convenient for carrying the curtain; at the same time, compared with the common fixing method such as the clamping fixing method, the fixing method provided in this embodiment can prevent the curtain from being damaged due to excessive force on the curtain, and can effectively protect the curtain. Among them, the use of the second sliding plate 1740, the spring 7130 and the fourth screw 1620 can adjust the force of the first sliding plate 1520 against the curtain, thereby preventing the curtain from loosening due to insufficient force between the two first sliding plates 1520 or the difficulty in installing and disassembling the curtain due to excessive force between the two first sliding plates 1520.

[0072] When the teaching and examination integrated system for personnel training based on Internet technology of this embodiment is used, the screen mounting seat 110 is first placed in front of the projector, and the first slot plate 410 and the second slot plate 710 in the first slide groove 120 are pulled. When the first slot plate 410 and the second slot plate 710 are pulled to the appropriate position, the first nut 1240 in the connector mounting cavity 113 is screwed to fix the first slot plate 410 and the second slot plate 720 in the first slide groove 120; then the first rotating rod 420 and the second rotating rod 720 are turned vertically, the second screw rod 610 in the first "T"-shaped slot 421 is passed through the third strip through hole 431, and the first rotating rod 420 and the first support plate 430 are fixed together by the second nut 620, the third screw rod 920 in the second "T"-shaped slot 910 is passed through the fourth strip through hole 731, and the second rotating rod 720 and the second support plate 730 are fixed together by the third nut 920. Place the two ends of the connecting rod 1300 in the third through hole 422 and the fourth through hole 722 respectively, and then fix the connecting rod 1300 between the third through hole 422 and the fourth through hole 722 by means of nuts. The thickened layer at the top of the curtain is clamped in the strip groove 1350 on the connecting rod 1300; the bottom of the curtain is clamped between the two first sliding plates 1630 on the sliding member 1520, and the force on the curtain can be adjusted by adjusting the fourth screw rod 1620. When the curtain mounting seat 110 is put away after use, the cover plate 310 is pushed into the square through hole 111 so that the first sliding groove 120 is in a relatively sealed environment.

[0073] In conclusion, the above is only a preferred embodiment of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the patent of the present invention.
