Description

Technical Field

[0001] The utility model relates to the technical field of popular science exhibits in science and technology museums, specifically an interactive experience device that displays the position changes of the Earth's North Pole magnetic pole. Background Art

[0002] In the science and technology museum industry, interactive experience devices (also called exhibits) are an important part of science and technology museums. Their purpose and function is to cultivate the audience's scientific interest and spirit of inquiry by allowing them to experience popular science exhibits, actively explore, learn scientific knowledge, scientific methods and scientific ideas.

[0003] The magnetic pole is a crucial component of polar knowledge, serving to educate the public about Earth's magnetic pole and magnetic field. Visitors can participate in and experience the exhibits, understanding that Earth's magnetic pole is not fixed but moves over time. They can also learn that the geographic pole and the geomagnetic pole are not located in the same place. By observing the interaction between an electromagnet and a magnetic needle, they can gain a basic understanding of the magnetic pole. The exhibit simulates the exploratory process that scientists used to discover the magnetic pole, allowing them to experience the scientists' fearless pursuit of truth.

[0004] Existing exhibits at science and technology museums primarily showcase information about the magnetic pole through graphic panels and video presentations. These exhibits are relatively simple, lacking interactivity and interest, and fall short of the museum's philosophy of hands-on learning and experience. Currently, no science and technology museums offer interactive displays showcasing the changing position of Earth's North Pole. Utility Model Content

[0020] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1 、 2As shown, the utility model proposes an interactive experience device for displaying the position change of the Earth's North Pole magnetic pole, including a magnetic pole detection device 1, a display 2, a control computer 3, multiple electromagnets 4 and a Arctic region map carrier 5. The multiple electromagnets 4 are buried in the Arctic region map carrier 5 to simulate the magnetic pole. The control computer 3 includes a touch screen 31 and a computer 32 electrically connected to the touch screen 31. The computer 32 is communicatively connected to the display 2 and the lower computer 33. The lower computer 33 is electrically connected to multiple coil switches 34. The multiple coil switches 34 are respectively electrically connected to the multiple electromagnets 4. The magnetic pole detection device 1 includes a shell and multiple groups of magnetic needles suspended by fine wires arranged in the shell.

[0022] The lower computer 33 is a control board based on a single chip microcomputer, such as a 51 single chip microcomputer or an STM32 series single chip microcomputer. The control board includes a coil switch driving circuit connected to the single chip microcomputer.

[0023] The housing of the magnetic pole point detection device 1 is a transparent housing with universal wheels installed at the bottom. The audience holds the magnetic pole point detection device and moves the device through the universal wheels. The transparent housing makes it easy to observe the direction of the magnetic needle.

[0024] The computer 32 and the slave computer 33 are connected via a serial communication port, such as an RS232 or RS485 interface.

[0025] The computer 32 is connected to the touch screen 31 via a USB interface and a video interface. The computer 32 is connected to the display 2 via a video interface. The video interface is an HDML interface.

[0026] The Arctic region map carrier 5 is drawn with longitude and latitude lines for calibrating simulated longitude and latitude.

[0027] The working principle of this utility model is:

[0028] The ground is covered with a map of the Arctic region, marked with longitude and latitude lines. Electromagnets are embedded at specific locations on the map to simulate the magnetic pole. The magnetic pole detection device contains a magnetic needle suspended by a thin wire. When placed above an energized electromagnet, the needle will point vertically toward the electromagnet. A display shows the task of finding the magnetic pole and the year in which viewers must explore and locate the magnetic pole. A control computer energizes the electromagnet representing the specific magnetic pole, and viewers submit their detected longitude and latitude using a touchscreen.

[0029] The specific operations are:

[0030] 1. Operate the touch screen, and the task release display will show a random year and be displayed on the monitor; 2. The control computer controls the electromagnet representing the magnetic pole of that year to be energized to generate a magnetic field; 3. The audience holds the magnetic pole detection device and uses the universal wheel mobile device to detect the position of the North Magnetic Pole on the ground North Pole map carrier. The magnetic needle will be deflected by the magnetic field, and the direction of the magnetic needle can be observed through the transparent shell; 4. If the magnetic needle of the detection device points vertically to the ground, it means that the magnetic pole has been found. Combined with the ground map information, the longitude and latitude coordinates are inferred; 5. Enter the longitude and latitude values ​​on the touch screen. If the location is correct, watch the animation video to learn related knowledge. If it is wrong, the audience will be prompted to continue looking for the location of the magnetic pole.

[0031] This device for detecting magnetic poles utilizes a durable, thin wire to suspend the magnetic needle, ensuring flexibility and preventing deflection. This device allows for easy observation of the needle's deflection while allowing for easy movement on the ground, without posing safety risks. The buried electromagnet can be individually powered on and off. During simulated detection, the distance between the electromagnet and the magnetic needle is kept at an appropriate distance, ensuring the needle's deflection is affected by the electromagnet.

[0032] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
