Abstract

The invention provides a carrier communication module detection device and a carrier communication module detection method. The technical problem that the overall detection cannot be realized in the prior art is solved. The device comprises a multi-way network test cabinet. The multi-way network test cabinet is connected with a concentrator communication cabinet. The concentrator communication cabinet comprises a concentrator. The concentrator communication cabinet is connected with a plurality of carrier meter communication cabinets which are connected in sequence. The carrier meter communication cabinets are connected with a carrier meter set. The carrier meter set comprises a plurality of carrier meters which are connected in series in sequence. The concentrator communication cabinet and the carrier meter communication cabinets are respectively connected with respective spectral instruments. Each carrier meter communication cabinet comprises a second attenuator. The second attenuator in a next carrier meter communication cabinet is connected with a previous carrier meter communication cabinet. The second attenuator in the front-most carrier table communication cabinet is connected with the concentrator communication cabinet. According to the invention, to-be-tested carrier communication meter reading equipment is arranged in the whole system, so that the overall use effect of the carrier communication meter reading equipment can be detected.

Description

technical field [0001] The invention belongs to the technical field of power carrier communication, and in particular relates to a power carrier communication module detection device and a power carrier communication module detection method. Background technique [0002] Power carrier communication is a data coupling multi-channel communication system based on frequency division multiplexing technology. According to different transmission media, carrier communication can be divided into open line carrier communication, symmetrical cable carrier communication, small coaxial cable carrier communication, medium coaxial cable carrier communication , submarine cable carrier communication and power line carrier communication, etc. With the development of power line carrier communication technology, the power sector has applied it to the work of power user data reading, thus gradually transforming the traditional manual meter reading method into automatic meter reading. However, d...
