Expansion connector, detection system and detection method

Abstract

The invention discloses an expansion connector, a detection system and a detection method, and relates to the technical field of detection. The expansion connector includes: a first end, used for connecting to the controller and taking power from the controller, including a signal output terminal; and a second end, used for connecting the detector and supplying power to the connected detector, and from The detector obtains the detection signal, including a signal input terminal, wherein the signal output terminal of the first end is connected to the signal input terminal of the second end; wherein, the first end or the second end has more than two branch ends . Therefore, the number of independent components used in the detection process is reduced, and the deployment complexity in the detection process is reduced.

Description

technical field

[0001] The invention relates to the technical field of detection, in particular to an expansion connector, a detection system and a detection method. Background technique

[0002] Various detectors are often used in industrial sites. Each detector is respectively connected to the signal input point with a quick connector connection line. The number of wires of the quick connector generally has two to five wires.

[0003] In the related art, a detector is used to place at a detection position to obtain a detection signal, and a controller of a processing system is used to determine a detection result according to the obtained detection signal. When it is necessary to detect N (N is a positive integer) detection positions, or when N independent controllers need to obtain detection signals, it is necessary to use N quick connector connecting lines and N power supply lines, and use the N interface.
