Problems solved by technology

The traditional detection method is to use 2M bit error meter, the disadvantage is that the instrument needs to be carried at any time, and if it is not a communication personnel, it will not be able to use it
Especially in remote sites, the operation and maintenance personnel of the substation are on site, but there is no way to cooperate

Embodiment 1

[0019] A power communication DDF unit includes a metal plate body 1, a name strip 2, connection terminals, and an LED lamp. The DDF unit is gray in appearance, reversible, and has a rotation angle of 180 degrees to facilitate the operation of the connector plug. A DDF unit is a 20-system unit board, which is divided into two rows, with 10 pairs in the upper and lower rows. The metal plate body is made of all-copper material, which has good corrosion resistance. The name strip is used for pasting labels, the length corresponds to the length of the unit board, a layer of transparent plastic on the outside, a long strip of paper inside, and one row at the top and bottom row. The connecting terminal is a 75 ohm unbalanced coaxial connector, the surface is gold-plated, the contact resistance is low, and the connection is reliable. 20 system unit boards, one system has 4 connection terminals. Generally, connecting terminal 3 is connected to the receiver on the service side, conne...

Abstract

The invention discloses a power consumption DDF (Digital Distribution Frame) unit which comprises a metal plate body, connection terminals and LED (Light-Emitting Diode) indication lamps, wherein theconnection terminals are arranged on the metal plate body; four connection terminals form one system; the LED indication lamps are arranged on the metal plate body; the number of the LED indication lamps corresponds to the number of the connection terminals; each LED indication lamp indicates a connection condition of two connection terminals; when the LED indication lamps are turned on, a resultthat the connection terminals are connected is shown; and when the LED indication lamps are turned off, a result that the connection terminals are disconnected is shown. According to the invention, byadditionally arranging LEDs, the power consumption DDF unit has the advantage of simplicity and intuition, and even though a user is not communication personnel, the user can also observe a conditionof a channel by the LED lamps and primarily judges whether a problem is an equipment problem or a channel problem, so that a probability of misoperation and false tripping is reduced.

Description

technical field [0001] The invention relates to a DDF unit, in particular to a DDF unit used in power communication. Background technique [0002] In the field of power communication, the DDF (Digital Distribution Frame) unit is an important part of it. The DDF unit can make the digital code stream connection of digital communication equipment into a whole. It is a wiring connection device between digital multiplexing equipment, digital multiplexing equipment and program-controlled switching equipment or non-phone service equipment. It has flexible wiring. , jumper, transfer and test functions. [0003] The DDF unit consists of several pairs of 2M terminals, carrying important services such as relay protection and dispatch automation. There are generally two reasons for business failures, one is terminal equipment failure, and the other is channel failure. The traditional detection method is to use 2M BER tester. The disadvantage is that the instrument needs to be carried...
