Description

Real-time monitoring system of optical junction box and its operation method

The present invention relates to a real-time monitoring system for optical connection enclosures and a method of operating the same, and more particularly, to enable a real-time check whether the optical connection enclosure is infiltrated from the outside without opening the optical connection enclosure, and in particular, optical Periodic data on humidity in the junction box can be managed, and when the data is interlocked with the monitoring operator (center), the problems of the existing optical transmission network monitoring system can be compensated for, thereby improving product quality and reliability. It is greatly improved so that users can provide good images.

The present invention is to find out that the inventor of the present invention is an invention of the Republic of Korea Patent Registration No. 0280379 (Application No. 1999-0019816) (name: optical cable connection enclosure maintenance system) is an improved invention.

In general, several connection points are required in the process of connecting an optical cable between a telephone company and a subscriber, and optical fiber connection materials such as optical cable junction box, optical intermediary box, or communal box are installed at these points. Connect it. The optical cable connection materials not only connect the optical cables that are disconnected from each other, but also serve to suppress a phenomenon in which the connection portion is deteriorated by an external environment. Among these, optical cable connection enclosures are mainly installed in manholes and the ground to protect the connection area of optical cables from the external environment.Manholes are often filled with contaminated water, unlike air. Because of the high degree of contamination, it should have better environmental protection than other connection materials. In particular, the optical cable junction box should have a sealing performance which basically prevents contaminated water from penetrating into the enclosure. If the enclosure is flooded and the fiber remains exposed to moisture, the fiber will lose its function. 1 is a graph illustrating a process of changing the strength of an optical fiber over time. 2 is a view showing the surface of the optical fiber in a normal environment, FIG. 3 is a view showing the surface of the optical fiber after being exposed to moisture for a long time, and FIG. 4 is a view of the surface of the optical fiber exposed to chemicals. As shown in each figure, when the optical fiber is exposed to moisture or chemicals, it can be seen that the optical fiber is damaged by adversely affecting the optical fiber.

As described above, it can be detected that the characteristics of the optical fiber is deteriorated only after a certain period of time in the state exposed to moisture. In other words, it can be seen that the communication equipment has occurred only after a long time in the state that the optical cable connection box is flooded, the consumer who benefits from the communication equipment has to bear the inconvenience such as communication error or disconnection.

The sealing method of the junction box for an optical cable can be classified into two types. There is a heat shrink type enclosure, which is the first generation of the junction box. In order to prevent water from penetrating into the enclosure, the heat shrinkable type is sealed with a jelly compound or the like in the sealed state of the junction box, or the junction box is waterproofed using a sealing tape or the like. have. Therefore, while the waterproof is guaranteed, there is a disadvantage that maintenance is impossible and requires a lot of time and expense required for branching of the communication line.

As the development of communication equipment and the demand for communication facilities increased rapidly, branching of communication lines was required. Therefore, a mechanical type junction box, which is a second generation of a junction box that can be opened to perform branching of a communication line, has been developed. This has the advantage of easy maintenance because it has a mechanical coupling means to facilitate the opening of the junction box. However, such a junction box may be incompletely coupled to the junction box due to abrasion of a worker or a machine in a process of performing a branching operation of a communication line, etc., and may repel water into the enclosure.

In addition, the conventional connection enclosure as described above is a situation that can be confirmed only by opening the enclosure whether the infiltration of water in the case of product aging due to failure of the enclosure itself or long time use. Conventional connection enclosures have to be dismantled and reworked when a problem occurs in the enclosure, causing a lot of manpower loss, and impossibility and economic losses due to the reusability of waterproof materials. Therefore, there is a demand for a technology that can confirm whether the enclosure is flooded without opening the enclosure.

In order to solve the above problem, the above-mentioned Korean Patent Registration No. 0280379 (Application No. 1999-0019816) has been filed and registered.

The alarm sound generator 24 for outputting the alarm sound by switching the alarm sound generating means according to the control signal of the digital signal by the analog-to-digital converter 21 The liquid crystal display unit 25 which displays the humidity detection result and the temperature detection result and the respective parameter information in the enclosure 10 which is converted into a signal and are represented by numbers or letters according to the control signal provided by the microcomputer 23, and the microcomputer ( The non-volatile memory device (ROM) incorporating a predetermined program necessary for the operation of 23) and the result of sensing the temperature and humidity provided through the analog / digital converter 21 and the operation or control signal of the microcomputer 23 are temporarily stored. When a print signal is input through the memory device 27 made up of a volatile memory device (RAM) and the key input unit 22, it is stored in the memory device 27 according to the control signal of the microcomputer 23. It provides an optical cable connection box maintenance system comprising an interface unit 26 for transmitting the temperature and humidity detection results to an external device such as a printer. .
