Description

2M Transceiver Quick Judgment Indicator

technical field

The invention relates to the technical field of communication detection tools, in particular to a 2M transceiver quick judgment indicator light.

Background technique

With the development of power communication, the communication between various substation sites has been completely replaced by optical communication, and the interface interface between optical transmission equipment and various business equipment is still dominated by 2M interface, and this connection interface is digital wiring There are two rows of interfaces on the communication side and the service side (usually the service port is the upper row, and the communication side is the lower row), and the middle is connected by a digital distribution frame. To make the communication normal, there must be two rows of upper and lower rows A pair of 2M interfaces correspond to sending and receiving, and the "receiving end" and "sending end" of the communication side correspond to the "sending end" and "receiving end" of the service test respectively, otherwise the service will not work. An important link in communication operation and maintenance is to determine the sending and receiving of 2M terminals. In the 2M maintenance process, judging the transmission and reception of 2M ports is a basic work that is often done first in 2M maintenance. Usually, 2M bit error testers and multimeters are used for testing. There are the following problems: 1. Due to the comparison of 2M interfaces Small, the red and black pointers of the multimeter are easily misjudged due to abnormal contact. This kind of business failure requires personnel to go to the scene again to deal with it, causing unnecessary trouble and affecting work efficiency; The size and weight are relatively large. In daily operation and maintenance, especially when performing daily substation inspection equipment, the 2M bit error tester and multimeter will not be brought with you at any time, and the 2M transmission and reception test cannot be carried out smoothly, which greatly affects improved operation and maintenance efficiency.

detailed description

In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with specific embodiments according to the accompanying drawings.

As shown in Figures 1, 2, and 3, the 2M transceiver fast judgment indicator light includes an outer protective cover 2, a light-emitting diode 8, a first interface 3, and a second interface 4, and an opening 7 is arranged on the top of the outer protective cover. The outer protective sleeve, the first interface, and the second interface are flexibly connected in sequence; the first interface includes the outer ring metal layer I13, the inner ring insulating layer I16, and the metal probe 17 in sequence from the outside to the inside. A connection column 15 is provided on the metal layer I of the outer ring at the top of the interface, and the anode 14 and the cathode 9 of the LED are respectively connected to the metal probe and the connection column of the first interface, and a metal shrapnel ring 10 (metal The front part of the shrapnel ring has a protruding part, which can make the interface clamp each other during the test after it is surrounded by the insulating layer of the inner ring, and the contact is more closely), the ring wall of the metal shrapnel ring is axially opened at an annular interval There are several card slots 19; the second interface includes an outer metal layer II18, an inner ring insulating layer II11, and a metal pinhole 12 from the outside to the inside, and the metal pinhole is composed of two semicircular metal sheets ( The front part of the metal pinhole is composed of two separated metal sheets, its internal diameter is slightly smaller than that of the metal probe, and it is elastic within a certain contraction range).

Preferably, in order to facilitate assembly and disassembly, the outer surface of the outer protective sheath and the first interface is provided with friction protrusions 1 .

Preferably, in order to facilitate the connection to other devices, the outer ring metal layer II of the second interface is provided with a rotating ring block 5 and a connecting thread 6 .

Among the above, the casing of the 2M transceiver quick judgment indicator light should be made of alloy materials with high strength, good processing performance, and good anti-corrosion and moisture-proof performance, so as to ensure that it will not be damaged when it is slightly dropped during use. The first interface Copper alloy is used with the second interface to meet the requirement of good electrical conductivity.

When in use, use the 2M transceiver fast judgment indicator light to directly test on the digital distribution frame, and directly use the first interface for direct testing. When the port is the sending end, the red light is on; when the interface is the receiving end, the indicator light is off. When the test object is a 2M interface, put the second interface on the first interface for testing. In the practice of more than four months, it can be found that the signal light is red and the signal recognition is quite high. The accuracy rate of the 2M sending and receiving test has reached 100%. The statistics of the work tickets and dispatch orders in these four months show that There is no case of going out for maintenance due to 2M transceiver test errors. In the process of use, it has been fully affirmed by the on-site operators in terms of practicability and convenience, and has met the pre-design requirements.

In order to understand the test stability of the interface connection, we conducted a 2M test operation performance test on the connection scheme between the first and second interfaces. By connecting it to a multimeter, the result is displayed using the multimeter pointer readout. The three schemes are: 1 screw-in type: use threaded interface from wide to narrow for tightening; 2 direct type: 2M interface is in direct contact with the test interface; 3 metal shrapnel ring: use shrinkable elastic metal shrapnel with card slot structure, and the results are shown in Table 1.

Table 1: Statistical Table of Interface Stability Test

From the statistical results in Table 1, the second scheme has a fast test time, but the stability is not good enough, while the first scheme is stable but time-consuming, and the third scheme has both short test operation time and test characteristics of stability.

The above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to specific embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced. Without departing from the spirit and scope of the technical solutions of the present invention, all of them shall be included in the protection scope of the claims of the present invention.
