Abstract

The invention discloses a control circuit for matched resistance of a communication network. The control circuit comprises a detection unit and a control unit connected with the detection unit, wherein the detection unit is used for detecting whether a node of the communication network is a main control computer or not, and the control unit is used for controlling the matched resistance of the communication network to access the communication network when the node of the communication network is the main control computer. According to the invention, the matched resistance of the communication network can automatically access the communication network without manual inserting.

Description

technical field

[0001] The invention relates to the field of circuits, in particular to a control circuit for matching resistance of a communication network. Background technique

[0002] At present, the installation position of the matching resistor in the communication network needs to be confirmed by the debugging or after-sales personnel according to the installed communication network nodes, and the matching resistor is a temporary electrical component that needs to be kept by debugging or after-sales personnel. In this kind of communication network, if there is an abnormality in the network, when debugging or after-sales personnel need to check the matching resistors, it is often difficult to find them, and the corresponding matching resistors are also easily lost. Therefore, how to automatically identify nodes and automatically connect matching resistors is proposed on the agenda.

[0003] Aiming at the problem in the related art that the communication network matchi...
