The present disclosure is described in relation to a signal detection system which detects signals from motherboards.
FIG. 1 illustrates an embodiment of a signal detection system. The signal detection system comprises a signal detection card 100 and a motherboard 200. The signal detection card 100 is configured to detect a signal from the motherboard 200. In at least one embodiment, each of the first interface 20 and the second interface 30 (shown in FIG. 2) is a hardware interface that allows the connection of external peripherals. In one example, each of the first interface 20 and the second interface 30 can be a THUNDERBOLT® interface.
FIG. 2 illustrates that the signal detection card 100 comprises a connecting plate 10, a first interface 20, a second interface 30, and a detection module 40. The detection module 40 comprises a voltmeter 50 and a current meter 60. The first interface 20 and the second interface 30 are mounted on the connecting plate 10. The first interface 20 is coupled to the motherboard 200.
The signal detection card 100 further comprises a load 70. In at least one embodiment, the load 70 is a sliding rheostat.
The second interface 30 is configured to couple to a display 80.
FIG. 3 illustrates that the connecting plate 10 comprises a first signal detection terminal 11, a second signal detection terminal 12, a sending terminal 13, a receiving terminal 14, and a ground terminal 15.
The first interface 20 comprises a signal detection terminal TBT, a sending terminal LSTX, a receiving terminal LSRX, and a ground terminal GND.
The second interface 30 comprises a signal detection terminal TBT, a sending terminal LSTX, a receiving terminal LSRX, and a ground terminal GND.
The voltmeter 50 is configured to detect a voltage value of a signal from the motherboard 200. The current meter 60 is configured to detect a current value of the signal from the motherboard 200.
When in use, the first interface 20 is coupled to the motherboard 200. The load 70 is coupled between the first signal detection terminal 11 of the connecting plate 10 and the second signal detection terminal 12. The first signal detection terminal 11 of the connecting plate 10 is coupled to the signal detection terminal TBT of the first interface 20. The second signal detection terminal 12 of the connecting plate 10 is coupled to the signal detection terminal TBT of the second interface 30. The sending terminal 13 of the connecting plate 10 is coupled to the sending terminal LSTX of the first interface 20 and the sending terminal LSTX of the second interface 30. The receiving terminal 14 of the connecting plate 10 is coupled to the receiving terminal LSRX of the first interface 20 and the receiving terminal LSRX of the second interface 30. The ground terminal 15 of the connecting plate 10 is coupled to the ground terminal GND of the first interface 20 and the ground terminal GND of the second interface 30.
The motherboard 200 sends the signal to the first signal detection terminal 11 of the connecting plate 10 and the second signal detection terminal 12 of the connecting plate 10 via the signal detection terminal TBT of the first interface 20. Adjusting the load 70 can change the current value and the voltage value. The motherboard 200 sends data information to the display 80 via the sending terminal LSTX of the first interface 20, the receiving terminal LSRX of the first interface 20, the sending terminal LSTX of the second interface 30, and the receiving terminal LSRX of the second interface 30.
When a user needs to detect the voltage value, two connecting terminals of the voltmeter 50 are coupled to the first signal detection terminal 11 of the connecting plate 10 and the ground terminal 15 of the connecting plate 10, respectively. When the user needs to detect the current value, the two connecting terminals of the current meter 60 are coupled to the first signal detection terminal 11 of the connecting plate 10 and the second signal detection terminal 12 of the connecting plate 10, respectively.
It is to be understood that even though numerous characteristics and advantages have been set forth in the foregoing description of embodiments, together with details of the structures and functions of the embodiments, the disclosure is illustrative only and changes may be made in detail, including in the matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
