Description

A Passive Online Monitoring System for Channel Encroachment of Communication Pipe Holes

technical field

The invention relates to a power equipment monitoring system, in particular to a passive on-line monitoring system for encroachment of a communication pipe hole channel.

Background technique

In urban municipal safety facilities, there are a large number of underground projects, including eight major pipelines (water supply and drainage, communication, electricity, gas, etc.). The safety of these underground commune facilities and municipal equipment is of great significance to the construction of a peaceful city. For a long time, there has been a shortage of "emphasis on the ground while ignoring the underground" in urban security construction, which has brought security risks. For example, waterlogging in many cities caused the loss of underground manhole covers and the safety of personnel; with the increase of Internet business companies, it is necessary to lay or lease optical fiber network channels. However, in order to save investment and procedures, it often happens that the cables in the optical fiber network lines of telecommunications and electric power (underground pipes, overhead poles, etc.) are invaded by illegal personnel for a long time, the power cables are stolen, or the communication pipe holes The channel is occupied by an external linear object cable intrusion. Among them, the illegal occupation of overhead poles can still be found through personnel inspections, but the underground communication pipes are difficult to be discovered in time due to their concealment, thus endangering the normal operation of urban power automation control. In recent years, in the construction of smart cities widely carried out in various places, more and more monitoring equipment gradually

It is applied to the safety monitoring of underground facilities.

However, these devices all need to be provided with an additional sensor, and it is easy to cause misjudgment.

Contents of the invention

The purpose of the present invention is to provide a passive on-line monitoring system for the encroachment of the communication pipe hole channel, which uses the communication optical cable in use, and passively monitors the communication pipe hole channel through optical scattering and spectrum multiplexing technology, and locates the channel in time And determined that the pipeline was illegally seized.

In order to achieve the above object, the present invention is achieved through the following technical solutions:

A passive online monitoring system for channel encroachment of communication pipe holes, which is characterized in that it includes:

The communication optical cable, which is laid in the pipe hole of the underground communication pipe, detects and transmits the information of the external disturbance source online while completing the normal communication;

The monitoring host is connected with the communication optical cable, and is used for receiving and analyzing the external disturbance source information transmitted by the communication optical cable.

The external disturbance source disturbs the communication optical cable, causing the communication optical cable to scatter a disturbance signal, and the monitoring host obtains the position information of the external disturbance source according to the disturbance signal.

The monitoring host further monitors the vibration data of the external disturbance source and combines the encroachment judgment rules to obtain the encroachment information of the communication pipe hole.

The encroachment judging rule is: when the vibration data of the external disturbance source extends along the same direction, it is judged that the communication pipe hole is encroached.

The communication optical cable senses the information of the external disturbance source through the principle of spectrum multiplexing.

Compared with the prior art, the present invention has the following advantages:

1. The present invention utilizes the communication optical cable in use, without additional laying and installation of sensing elements or cables;

2. Passive online monitoring of communication pipe hole channels through optical scattering and spectrum multiplexing technology;

3. Timely discover external disturbance sources and accurately determine the entry of external linear objects to achieve the purpose of intelligently determining illegal occupation of pipelines.

Fig. 1 is a system diagram of a passive online monitoring system for channel encroachment of communication pipe holes according to the present invention.

detailed description

The present invention will be further elaborated below by describing a preferred specific embodiment in detail in conjunction with the accompanying drawings.

As shown in Figure 1, a passive online monitoring system for channel encroachment of a communication pipe hole includes: a communication optical cable 3, which is laid in the pipe hole 2 of the communication underground pipe 1, and is detected and detected online while completing normal communication. Transmission of external disturbance source information; monitoring host 6, which is connected to the communication optical cable 3 through the connecting optical fiber 5, for receiving and analyzing the external disturbance source information transmitted by the communication optical cable.

The external disturbance source 7 disturbs the communication optical cable 3, causing the communication optical cable 3 to scatter a disturbance signal, and the monitoring host 6 obtains the position information of the external disturbance source according to the disturbance signal.

The above-mentioned monitoring host 6 further monitors the vibration data of the external disturbance source and combines the encroachment judgment rules to obtain the encroachment information of the communication pipe hole.

The above-mentioned encroachment judgment rule is: when the vibration data of the external disturbance source extends along the same direction, it is judged that the communication pipe hole 2 is occupied.

The above-mentioned communication optical cable 3 realizes the communication and sensing of the communication optical cable through the spectrum multiplexing technology, so that the communication optical cable in use can be used to passively monitor the communication pipe hole channel through the optical scattering and spectrum multiplexing technology.

Please continue to cooperate and refer to Figure 1. When the present invention is applied, in the existing communication optical cable, the principle of spectrum multiplexing is used to make the communication optical cable carry the original communication task and sense the external disturbance source information, and the external disturbance source 7 disturbs the communication. The optical cable 3, so that the communication optical cable 3 scatters a disturbance signal, the monitoring host 6 obtains the position information of the external disturbance source 7 according to the disturbance signal, and the monitoring host 6 further monitors the vibration data of the external disturbance source and combines it with the judgment of encroachment According to the rules, the channel encroachment information of the communication pipe hole is obtained. When the vibration data of the external disturbance source is along the same direction and extends, it is judged that the communication pipe hole 2 is occupied. For example, it is first detected at 251m in the communication pipe hole Disturbance source disturbance, while detecting the fluctuation of the disturbance source in a certain direction and extending to 261m, 271m..., big data analysis, it can be judged that there are external linear objects (cables, etc.) entering the communication row In the pipe hole, illegally occupy our communication pipe hole.

In summary, the present invention is a passive online monitoring system for the encroachment of the communication pipe hole channel, which uses the communication optical cable in use, and uses the optical scattering and spectrum multiplexing technology to passively monitor the communication pipe hole channel, and timely Locate and determine illegal occupation of pipelines.

Although the content of the present invention has been described in detail through the above preferred embodiments, it should be understood that the above description should not be considered as limiting the present invention. Various modifications and alterations to the present invention will become apparent to those skilled in the art upon reading the above disclosure.
