| titleOfInvention | Weakening the iron film on the root surface to promote the absorption of heavy metals by wetland plants Detector and detection device |
| abstract | The invention discloses a detector and a detection device for weakening the iron film on the root surface and promoting the absorption of heavy metals by wetland plants. A relatively pure electrical signal with a certain resonant frequency, the obtained change in the voltage difference between the two ends of the resonant circuit will be fed back to the constant current circuit through the comparison amplifier to compare with the preset reference voltage, and the result of the comparison will output the power supply voltage at the expected voltage and current Work within the fluctuation range; the conversion circuit converts the original electrical signal into an optical signal first, and then into an electrical signal, which not only plays the role of isolation between modules, avoids the traction effect, but also obtains a good voltage signal output that can eliminate glitches as much as possible. It is beneficial to the accuracy of detection; the voltage stabilizing amplifier circuit amplifies the weak electrical signal to the signal range that the peripheral equipment can process, so as to ensure the normal operation of subsequent signal processing. |
