Detailed Description

The principle of electromagnetic induction of an electrified coil is as follows: an electromagnet is a device that is energized to produce an electromagnet. An electrically conductive winding matched to the power of the core is wound on the outside of the core, and the coil, which is energized with current, has magnetic properties like a magnet, which is also called an electromagnet (electromagnet). It is usually made in the shape of a bar or a shoe to make the core easier to magnetize. In addition, in order to immediately demagnetize the electromagnet when the electromagnet is powered off, the electromagnet is usually made of soft iron or silicon steel materials with fast demagnetization. When the electromagnet is electrified, the electromagnet has magnetism, and the magnetism disappears along with the electrification after the electromagnet is powered off. The electromagnet has wide application in daily life, and the power of the generator is greatly improved due to the invention of the electromagnet. When the iron core is inserted inside the energized solenoid, the iron core is magnetized by the magnetic field of the energized solenoid. The magnetized core also becomes a magnet, so that the magnetism of the solenoid is greatly enhanced because the two magnetic fields are superposed with each other. In order to make the electromagnet more magnetic, the iron core is generally made into a shoe shape. However, it should be noted that the winding direction of the coil on the horseshoe is opposite, one side is clockwise, and the other side is counterclockwise. If the winding directions are the same, the magnetizing actions of the two coils on the iron core are mutually counteracted, so that the iron core does not show magnetism. In addition, the iron core of the electromagnet is made of soft iron, but cannot be made of steel. Otherwise, once the steel is magnetized, the magnetism of the steel can be kept for a long time and the steel cannot be demagnetized, and the strength of the magnetism of the steel cannot be controlled by the magnitude of the current, so that the advantages of the electromagnet are lost.

The property advantages and the application of the electromagnet are as follows: the electromagnet is a device which can generate magnetic force by passing current, belongs to a non-permanent magnet, and can easily start or eliminate the magnetism of the electromagnet. For example: large cranes use electromagnets to lift waste vehicles. When an electric current is passed through the wire, a magnetic field is generated around the wire. By this property, a uniform magnetic field is created within the solenoid when a current is passed through the solenoid. If a ferromagnetic material is placed in the center of the solenoid, the ferromagnetic material is magnetized and the magnetic field is greatly enhanced.

Generally, the magnetic field generated by an electromagnet is related to the magnitude of the current, the number of turns of the coil, and the ferromagnetic body in the center. When designing electromagnets, the distribution of the coils and the selection of the ferromagnet are emphasized and the magnitude of the current is used to control the magnetic field. This limits the magnitude of the magnetic field that can be generated by the electromagnet due to the resistance of the coil material, but with the discovery and application of superconductors, there is an opportunity to exceed existing limits.

Electromagnets have many advantages: the magnetism of the electromagnet can be controlled by switching on or off the current; the magnetic strength can be controlled by the strength of current or the number of turns of the coil; the magnetic size can also be controlled by changing the resistance to control the current size; its magnetic poles may be controlled by changing the direction of the current, etc. Namely: the strength of magnetism can be changed, the existence of magnetism can be controlled, the direction of a magnetic pole can be changed, and the magnetism can disappear due to the disappearance of current.

The vehicle deceleration protection system is shown in fig. 1, a pedestrian path 10 is arranged on the outer side of a running road 8, an induction belt 7 is arranged at the edge of the sidewalk 10, which is positioned on one side of the running road 8, the induction belt 7 used for inducing the position of a vehicle 9 is connected with a control system, electromagnetic coils 3 are arranged on a railing 2 and the vehicle 9 on the other side of the sidewalk 10, the electromagnetic coils 3 of the vehicle 9 are arranged on the front part and the lower part of a vehicle body, the electromagnetic coils 3 are connected with the control system and a power supply, when the vehicle 9 contacts the induction belt 7, the induction belt 7 transmits signals to the control system, the control system controls the electromagnetic coils 3 of the vehicle 9 and the electromagnetic coils 3 on the railing 2, which correspond to the vehicle, to be electrified to generate a magnetic field, and the magnetic poles of; when the speed of the vehicle 9 is reduced to a fixed value, the electromagnetic coils 3 corresponding to the position of the vehicle 9 on the control railing 2 are controlled by the control system to form N, S poles which are alternately distributed, and the magnetic poles of the electromagnetic coils on the vehicle 9 are alternately distributed, so that the vehicle 9 is decelerated to stop.

The anti-collision principle is as follows: the induction belt 7 is arranged on the boundary part of the sidewalk, when a vehicle is out of control and collides with the sidewalk, the induction belt 7 induces the vehicle and transmits a signal to the control system, the control system controls the electromagnetic coil 3 on the railing 2 to be automatically opened, firstly, the system is applied to the railing of a high bridge, each section of the railing is provided with a plurality of electromagnetic coils and can generate a large magnetic force action, when the vehicle has an abnormal condition, the vehicle can run out of a running road and pass through the induction belt, the vehicle 9 enters the collision deceleration zone 6, the induction belt is used for detecting the position information of the vehicle and timely triggering the electromagnetic coils 3 on the railing 2 and the vehicle 9, when the vehicle 9 passes through a certain point of the induction belt 7, the electromagnetic coils 3 on the railing 2 are triggered to generate a magnetic field from the point, the induction belt 7 synchronously triggers the induction coils on the vehicle 9 at the same time, and the electromagnetic coils on, thereby produce the exclusive effect, until the speed of vehicle reduces to a definite scope, vehicle 9 gets into buffering guide zone 4, the solenoid of vehicle triggers and the coil of railing triggers synchronous control, guarantee safe speed reduction, buffering guide zone 4 is mainly that the electromagnetic action of a small amount of propulsion coil forms the guidance magnetic field, make the vehicle travel along the railing of vehicle guide zone, and make the vehicle safe speed reduction, the effect of setting up buffering guide zone is that prevent that the vehicle from once more returning to the road of traveling again because the magnetic pole repulsion effect in railing striking deceleration zone, produce the secondary and collide. Set up reinforcing apparatus at the railing simultaneously, prevent to make the railing topple over because effort and reaction force.

The electromagnetic principle of the device is shown in fig. 2, when a vehicle triggers an induction band, the current of the electromagnetic coil 3 impacting the deceleration area 6 is controlled to be N pole, the magnetic pole of the vehicle is also N pole, the magnetic poles of the vehicle 9 and the impact deceleration area 6 are the same, so strong magnetic force is generated to decelerate the vehicle to a very low fixed value, after deceleration is completed, the vehicle enters the buffer guidance area, the magnetic pole distribution of the guidance area is N, S pole alternate distribution, the magnetic poles on the vehicle 9 are changed to alternate distribution under the control of the control system, the vehicle enters the non-magnetic pole area through short acceleration, and the vehicle gradually decelerates to zero, and the safety of the vehicle is ensured. As shown in the left side of fig. 2, the induction has two functions, the first one is used as a circuit switch, the second one is used for inputting a 1 signal into the computer, 5 gate circuits are connected through a control system of the computer shown in the figure, 0 or 1 is output through 5 nand gates to control the current direction, the current direction is controlled by 0 to generate a magnetic pole N, and the current direction is controlled by 1 to generate a magnetic pole S.

The magnetic pole anti-collision system increases the acting time of force and changes the stress condition of the vehicle by the buffer action of magnetic force according to the momentum conservation law of Ft ═ m delta v, so that the damage of the vehicle is reduced, and the problem of traffic accidents is solved rapidly in real time by the real-time control action of the circuit, thereby avoiding the uncertainty of safety airbags and serious personnel and vehicle damage caused by the special condition (the vehicle falls down from the high altitude); through a logic circuit of a computer system, the NAND gate circuit is utilized to control the current direction, so that the magnetic pole direction is changed, the problem of different magnetic pole distribution in an anti-collision area and a buffer conducting area is further solved, and the vehicle is properly accelerated and slowly decelerated by utilizing quincunx distribution of the magnetic poles; the electromagnetic coil, the logic circuit, the anti-collision system and the force are analyzed and combined together, and an advanced anti-collision system controlled by a computer is formed by utilizing the physical basic principles of acting force, reacting force, momentum theorem and mutual repulsion of like magnetic poles.
