Abstract

The invention relates to a detection circuit and a multi-branch recognition device. The detection circuit is used for detecting and receiving or transmitting a pulse current signal, and comprises a current-voltage conversion circuit, a primary amplification circuit, a bias circuit and a secondary amplification circuit, wherein the current-voltage conversion circuit comprises a current transformerand a first operational amplifier; the current transformer is used for reducing a first current signal input by the primary side of the current transformer; the first operational amplifier is used forconverting a second current signal output by the secondary side of the current transformer into a first voltage signal; the primary amplification circuit is used for amplifying the first voltage signal into a second voltage signal and outputting the second voltage signal; the bias circuit is used for providing a bias voltage signal; and the secondary amplification circuit is used for amplifying the sum of the second voltage signal and the bias voltage signal into a third voltage signal. Compared with a detection circuit in a traditional identification device, the detection circuit disclosed by the invention is higher in sensitivity and solves the problem of information crosstalk during recognition.

Description

technical field [0001] The invention relates to the technical field of power supply, in particular to a detection circuit and a multi-branch identification device. Background technique [0002] How to meet the people's power demand for a better life, promote the lean management of the low-voltage distribution network, and get through the last mile of contact with customers is particularly important. For a long time, the accuracy of distribution network low-voltage basic data has been the main problem in promoting lean management of distribution network. The accuracy of data associations such as low-voltage topology, equipment specifications, low-voltage meters, and customer information is very low. It is imperative to sort out low-voltage households and customer information. . However, the power supply relationship in the low-voltage station area is complicated, the power supply lines are crossed, and the cables are laid underground. Information crosstalk is prone to occur ...
