A resistive element, for example, is a traditional cylindrical resistor, whose resistance value is indicated by multiple colored rings distributed along the side of the cylindrical element. This portable resistance measuring device also includes an analog resistor. The analog resistor, for example, mimics the shape of a resistive element in a portable size. This device can improve resistance measurement efficiency and effectively assist visually impaired individuals and beginners in learning electrical knowledge.

The following are several examples of implementation to illustrate the technical features of this invention, but the technical features of this invention are not limited to the examples of implementation listed above.

Figure 1 is a schematic diagram of the three-dimensional structure of a portable resistance measuring device according to an embodiment of the present invention. Referring to Figure 1 , the portable resistance measuring device according to an embodiment of the present invention includes a housing 20. Housing 20 is, for example, a six-sided box-shaped structure having an upper surface 30 and a lower surface 32. In practice, the shape of housing 20 is not limited to the six-sided box structure shown. Upper surface 30 is located on the exterior of housing 20. Circuit module 16 is disposed within housing 20, for example, on lower surface 32 of housing 20. For example, charging port 12, test port 18, analog resistor 10, and screen 22 are disposed on upper surface 30 of housing 20.

Test port 18 can be electrically connected to an electronic component under test, such as resistor 17. Analog resistor 10 is disposed on top surface 30 of housing 20 and electrically connected to circuit module 16, enabling circuit module 16 to control analog resistor 10. Analog resistor 10 includes, for example, multiple light-emitting elements 10a-10d. These light-emitting elements 10a-10d form a light-emitting pattern.

FIG3 is a schematic diagram of the structure of the analog resistor of the portable resistance measuring device according to an embodiment of the present invention. Please also refer to FIG3 for the portion of the analog resistor 10. According to an embodiment of the present invention, the analog resistor 10 includes a plurality of light-emitting elements 10a~10d, of which four light-emitting elements 10a~10d are activated to emit light, and the actual number of light-emitting elements 10a~10d is determined according to the actual manufacturing needs. The shape structure of the analog resistor 10 simulates the geometric structure of the resistor to be measured 17, such as a columnar structure. The resistor to be measured 17 is, for example, a resistor with four colored rings, and these four colored rings traditionally indicate its resistance value. However, the light-emitting elements 10a~10d are not limited to being ring-shaped. Thus, in the embodiment corresponding to the resistor 17 to be measured, four light-emitting elements 10a-10d among the plurality of light-emitting elements are activated to emit corresponding colored lights. In conjunction with the resistance value measured by the resistor 17 to be measured, a plurality of light-emitting rings are formed to form a light-emitting pattern in accordance with the resistance value.

In other words, the multiple light-emitting elements 10a-10d of the analog resistor 10 are controlled by the circuit module 16 to emit variable light patterns to indicate the resistance value. The circuit module 16 also measures the resistance of the resistor under test 17 via the test port 18. As can be seen, different resistors under test 17 may have different resistance values, so the multiple light-emitting elements 10a-10d will also produce different and corresponding light patterns.

The upper surface 30 of the housing 20 may also include a screen 22. Regarding the circuit connection, the screen 22 is electrically connected to the circuit module 16 via a connection wire set 34. The screen 22 can display the measured resistance value of the resistor under test 17, that is, the resistance value of the luminous pattern, in digital form.

According to one embodiment, a test port 18 may be provided on the upper surface 30 of the housing 20. The test port 18 may be connected to the circuit module 16 via a connection line 34, for example, to perform control operations. The screen 22 may display the resistance value measured by the test port 18.

The following describes the circuit architecture of a portable resistance measuring device according to one embodiment. Figure 2 is a schematic diagram of the circuit architecture of a portable resistance measuring device according to one embodiment of the present invention, corresponding to Figure 1 . Referring to Figure 2 , communication between the circuit module 16 , the test port 18 , the screen 22 , and the multiple light-emitting elements 10 a , 10 b , 10 c , and 10 d of the analog resistor 10 is achieved via a plurality of connection lines 34 , enabling bidirectional communication. During measurement, test port 18 can be connected to an electronic component, such as resistor 17 to be measured. The resistance value read is transmitted via circuit module 16 to screen 22, controlling a portion of the multiple light-emitting elements 10a-10d of analog resistor 10 to emit corresponding colored light, such as red, blue, green, or black. Each light-emitting element 10a-10d is comprised of, for example, red (R), green (G), or blue (B) light-emitting diodes (LEDs), and the color is controlled using RGB color values.

As is known in the art, the control mechanism of circuit module 16 may be comprised of at least one chip, including a programmable chip. Circuit module 16 communicates signals bidirectionally with connected components via a plurality of connection lines 34 to achieve the desired control. The control architecture of circuit module 16 can be customized as needed using conventional techniques and will not be described in detail here.
