[0002] A nonlinear time-delay system refers to a system with time-delay characteristics, in which the state and output variables of the system cannot be described by a linear relationship under the influence of external conditions. Such systems are widely present in real life, such as power systems, metallurgical industrial processes, mechanical transmission systems, network control systems, etc. The study of nonlinear time-delay systems has important theoretical and practical significance. On the one hand, many actual systems exhibit nonlinear time-delay characteristics, so it is necessary to conduct in-depth research on such systems to understand their dynamic behavior and stability. On the other hand, by studying nonlinear time-delay systems, theoretical guidance can be provided for the design and optimization of actual control systems. Generally, nonlinear time-delay observations need to be observed through a display screen.

[0036] The power connection moving component 6 includes an upper power connection part 6a installed inside the protection cabinet 1 and a lower power connection part 6b installed inside the protection cabinet 1. The upper power connection part 6a and the lower power connection part 6b are respectively arranged on the upper and lower sides of the installation groove 2. The power connection moving component 6 includes a moving groove 601 opened inside the protection cabinet 1. The side of the moving groove 601 away from the installation groove 2 is symmetrically provided with a rod groove 602. The rod groove 602 penetrates to the outside of the protection cabinet 1. The inside of the moving groove 601 is movably installed with a moving plate 603. The moving plate 603 is fixed on the side away from the installation groove 2. A pressure rod 604 is installed, and the pressure rod 604 passes through the rod groove 602. A compression spring 605 is symmetrically installed on one side of the moving plate 603 away from the pressure rod 604. The compression spring 605 is fixedly connected to the inner wall of one end of the moving groove 601 close to the installation groove 2. A conductive rod 606 is installed on the moving plate 603. Contacts 607 are fixedly installed on the inner walls of both sides of the moving groove 601. When the pressure rod 604 is pressed and moves downward to the limit position, the two ends of the conductive rod 606 are respectively in contact with the two contacts 607, and the two contacts 607 on the upper electrical connection part 6a are in contact with each other. The two contacts 607 on the upper and lower electrical connection parts 6a and 6b are respectively connected in series with the moving electromagnet 309. When the conductive rod 606 on the upper electrical connection part 6a contacts the contact 607, the moving electromagnet 309 is connected to a positive current, so that the moving electromagnet 309 generates a repulsive force on the limit slot 308. When the conductive rod 606 on the lower electrical connection part 6b contacts the contact 607, the moving electromagnet 309 is connected to a reverse current, so that the moving electromagnet 309 generates an attractive force on the limit slot 308. When the baffle 4 rotates downward to the bottom of the protection cabinet 1, it can push The movable plate 603 on the lower electrical connection part 6b moves upward, so that the conductive rod 606 contacts the contact 607, so that the movable electromagnet 309 generates an attractive force on the movable magnetic block 306. When the baffle 4 rotates upward to above the protection cabinet 1, it can push the movable plate 603 on the upper electrical connection part 6a to move downward, so that the movable electromagnet 309 generates a repulsive force on the movable magnetic block 306, which is convenient for adjusting the position of the display screen body 301 when the outdoor environment is different, thereby facilitating the nonlinear time-delay observation of the display screen body 301 in the outdoor environment.

[0037] Working principle: when moving, the protection cabinet 1 is installed on the mobile frame and moved to the desired position. When not in use, the baffle 4 is set on the front of the protection cabinet 1, so that the protection cabinet 1 and the baffle 4 protect the display screen body 301. At this time, the insertion rod 504 is inserted into the slot 511 to fix the baffle 4.

[0038] When the display screen body 301 is used to observe the nonlinear time lag of the device on a sunny day, the retraction electromagnet 508 on the upper connecting member 5a is energized through the control panel 7 to generate an attraction force on the retraction magnetic block 507, so that the insertion rod 504 enters the inside of the side tube 502, and the insertion rod 504 is moved out of the slot 511. At the same time, the drive motor 513 on the lower connecting member 5b is energized. At this time, since the insertion rod 504 on the lower connecting member 5b is inserted into the inside of the slot 511, and the block 512 is inserted into the inside of the slot 505, the drive motor 513 is turned on, driving the rotating block 510 to rotate, and then driving the baffle 4 to rotate toward the bottom of the protective cabinet 1 until it rotates to a horizontal state. During the movement, the baffle 4 generates pressure on the pressure rod 604 on the lower power connection part 6b, and after pushing the moving plate 603 to move, the two ends of the conductive rod 606 are in contact with the two contacts 607. When the conductive rod 606 on the lower power connection part 6b is in contact with the contacts 607, the moving electromagnet 309 is supplied with current to generate the same magnetic force as the moving magnetic block 306. Under the action of the repulsive force, the display screen body 301 moves outward to the outside of the installation slot 2, so as to facilitate the heat dissipation of the display screen body 301 when in use. In addition, since the baffle 4 rotates to be located below the protective cabinet 1, it is convenient to support and protect the display screen body 301, so as to prevent the display screen body 301 from being directly dropped to the ground by the impact force.

[0039] When the display screen body 301 is used to observe the nonlinear time lag of the device on a rainy day, the retraction electromagnet 508 on the lower connecting member 5b is energized through the control panel 7, and the driving motor 513 on the upper connecting member 5a is energized, thereby driving the baffle 4 to rotate upward to a horizontal state. Since the baffle 4 is arranged above the protection cabinet 1, it plays a role in protecting the display screen body 301 from rain. When the baffle 4 rotates to above the protection cabinet 1, pressure is generated on the pressure rod 604 on the upper electrical connection member 6a. When the conductive rod 606 on the upper electrical connection member 6a contacts the contact 607, current is passed through the moving electromagnet 309 to generate a magnetic force opposite to that of the moving magnet 306. Under the action of the attraction, the display screen body 301 moves toward the innermost part of the mounting slot 2, further improving the rain protection effect of the display screen body 301.
