摘要:
A signal adaptive adjustment system (10) and signal adaptive adjustment method of biosensors. The signal adaptive adjustment method comprises the steps of: (S31), controlling a double-throw switch (2) to be off so as to enable the voltage difference between a positive electrode input end and a negative electrode input end of a biosensor circuit (7) to be zero; (S32), adjusting the resistance value of a first potentiometer (3) and synchronously adjusting the resistance value of a second potentiometer (4) so as to adjust the voltage at an output end of the biosensor circuit (7) to be zero; (S34), controlling the double-throw switch (2) to be on so as to enable bioelectrical signals detected by a detection head (1) to be outputted to the biosensor circuit (7); (S35), measuring the signal strength of the bioelectrical signals outputted by the biosensor circuit (7); and (S37) adjusting the resistance value of a third potentiometer (5) and synchronously adjusting the resistance value of a fourth potentiometer (6) to dynamically adjust the bioelectrical signals within a preset strength threshold range outputted by the biosensor circuit (7). The signal adaptive adjustment system (10) can eliminate the temperature drift phenomenon in the biosensor circuit (7), and can also adaptively output bioelectrical signals with appropriate strength, thereby stabilizing the output electrical characteristics of the biosensor, and improving the sensitivity of the biosensor.La présente invention concerne un système de réglage adaptatif du signal (10) et un procédé de réglage adaptatif du signal de biocapteurs. Le procédé de réglage adaptatif du signal comprend les étapes consistant : (S31) à commander l'arrêt d'un commutateur bidirectionnel (2), de façon à permettre à la différence de tension entre une extrémité d'entrée d'électrode positive et une extrémité d'entrée d'électrode négative d'un circuit de biocapteur (7) d'être nulle ; (S32) à régler la valeur de résistance d'un premier poten
