Detection Method and Corresponding Detection Device

A detection method configured to detect signal transmission performance of a signal cable in a detection liquid, the detection method comprising:

• providing a detection tank, wherein the detection tank comprises a liquid accommodation space and a non-liquid accommodation space, and the liquid accommodation space is configured to accommodate the detection liquid;
• providing a detection module, wherein the detection module comprises a detection substrate, the detection substrate comprising a substrate dry zone, a substrate wet zone, a substrate detection unit, and a substrate engaging port, wherein the substrate detection unit is located in the substrate dry zone, and the substrate engaging port is located in the substrate wet zone;
• placing the detection module into the detection tank, such that the substrate dry zone is disposed in the non-liquid accommodation space, and the substrate wet zone is disposed in the liquid accommodation space;
• and
• immersing the signal cable in the detection liquid within the liquid accommodation space to engage the substrate engaging port, and enabling the substrate detection unit to generate a detection signal in the non-liquid accommodation space and transmit the detection signal to the signal cable through the substrate engaging port, so as to make the signal cable perform a simulated signal transmission operation in the detection liquid, and thereby to detect the signal transmission performance of the signal cable in the detection liquid.
