The invention belongs to the field of network neural cable detection, in particular to a system and method for detecting the breakage of municipal buried cables based on the network neural cable.

Background technique

With the continuous advancement of science and technology, the version of the cable is also iteratively updated. Now the cable has a "network nerve" called the network nerve cable. Three sensing functions of "break": sensing "heat", monitoring the temperature of the cable body; sensing "pain", monitoring the vibration state of the cable body and the external laying environment; Monitor the circuit breakage caused by natural factors and other reasons. In addition, the "Network Neural Cable" cooperates with the GIS geographic information system to accurately locate the position of the laid cables on the satellite map.

With the rapid development of the city, the space requirements for overhead lines above the city ground are constantly shrinking, and it has become an inevitable trend to replace the overhead lines with underground cables. In urban construction such as road reconstruction and subway construction, buried cables are frequently damaged; especially after municipal buried cables are damaged, it will have a great impact on a large number of public power supply facilities, and the detection of cable breakage Point work is the core of the entire cable repair work.

Therefore, the detection and search of the damaged points of municipal buried cables is the top priority of the entire cable repair and recovery process.

The patent with the application number CN201810046118.6 discloses an underground cable fault detection system and a fault detection method thereof. The underground cable fault detection system includes: cable fault location equipment, including a low-voltage pulse signal source, a high-voltage pulse signal source, and a high-speed receiving device , used for signal detection by low-voltage pulse reflection method and flashover method, cable path detection equipment, including AC high-voltage signal source and electromagnetic induction receiving device, AC high-voltage signal source frequency amplitude is adjustable, AC high-voltage signal source stimulates the cable to be tested to generate Electromagnetic field, the electromagnetic induction receiving device detects the electromagnetic field generated by the cable to be tested, and the fault point detection equipment includes a high-voltage pulse signal source, a DC signal source, an AC signal source, a step voltage receiving device, an electromagnetic induction receiving device and an acousto-magnetic synchronization receiving device. This system can be widely used in the detection of open-circuit, short-circuit, grounding, low-resistance, high-resistance flashover and high-resistance leakage faults of underground cables to obtain more accurate fault points.

However, the above-mentioned patents have the following problems:

The above-mentioned patent can obtain the fault point more accurately, but in practical application, the breaking loss of the cable is not necessarily in the unit of "point", and there may also be a breaking loss in the unit of "segment".

Therefore, it is necessary to design the breakpoint detection based on the network neural cable, not only to be able to detect the breakage point of the broken cable, but to be able to detect the complete damaged segment composed of multiple breakage points.

Based on this, the present invention provides a municipal buried cable breakage detection system and method based on a network neural cable to solve the above problems.

SUMMARY OF THE INVENTION

In view of the deficiencies of the above-mentioned prior art, the technical problem to be solved by the present invention is: how to provide a system and method for detecting the breakage of municipal buried cables based on network neural cables, which can not only detect the breakage point of the broken cable, but also Ability to measure complete damaged segments consisting of multiple breakage points

In order to solve the above-mentioned technical problems, the present invention adopts the following technical solutions: a municipal buried cable breakage detection system based on a network neural cable, including a source generating device and a breakage detection device;

The source generating device is used for applying vibration force to the road surface of the line to be tested;

The breakage detection device is used to connect with the connecting equipment in the municipal cable well and determine the specific breakage section of the cable breakage area.

How this scheme works:

First use the breakage detection device to conduct power-on detection, and then determine the specific breakage range of the cable breakage area, and then use the source generator to apply vibration force to the road surface of the line to be tested, and the municipal cable is subjected to vibration force, and then use the breakage detection device. Detect the optical cable in the municipal cable, determine the specific breakage point, and obtain the specific breakage section through all the breakage points.

The method for detecting the breakage of municipal buried cables based on network neural cables includes the following steps:

Determine the cable breakage area;

Select the detection starting point according to the cable breakage area;

Cable detection steps: conduct power-on detection on the detection starting point, and determine the detection route according to the continuity of the municipal electrical equipment;

Optical cable detection steps: use the source generating device to apply vibration force to the road surface in the broken range in turn, and at the same time conduct optical cable vibration detection on the detection route to determine the actual broken point;

The actual breakage segment is determined according to the actual breakage point.

Methods for determining the area of cable breakage include:

View the area where the municipal electrical equipment stops working through the municipal electrical equipment management platform;

Select the detection starting point according to the cable breakage area:

In actual detection, because the cable breakage area is different, the detection efficiency is also different according to the selected detection starting point.

When the cable breakage area is less than or equal to one kilometer, it is more efficient to select the boundary area of the cable breakage area as the detection starting point (that is, to detect sequentially from one end of the cable breakage area to the other end); and when the cable breakage area is greater than At one kilometer, it is more efficient to select the central area of the cable breakage area as the detection starting point, because the cable breakage area is larger at this time, and the sequential detection efficiency is too low. Using the dichotomy method for detection can improve the detection efficiency.

After selecting the detection starting point, find the cable well corresponding to the detection starting point; use the breakage detection device to connect with the connecting equipment in the cable well, start the cable detection equipment, and observe the continuity of the municipal electrical equipment through the municipal electrical equipment management platform or with the naked eye. , to determine whether there is an actual fault point upstream or downstream of the detection starting point. When the municipal equipment upstream or downstream of the detection starting point is all turned on, there is no actual fault point on the line. Then the line has an actual fault point, and a new detection starting point (ie, the actual fault point) needs to be selected according to the conduction of the municipal electrical equipment;

Determine the actual fault point, find the cable well corresponding to the actual fault point, use the breakage detection device to connect with the connection equipment in the cable well, start the optical cable detection device, and use the source generator to make the source generator along the two sides of the actual fault point. The road surface vibrates, and the actual breakage point is determined according to the optical cable detection equipment. If the sensing signal in the cable changes during the vibration, the section of the optical cable is intact, that is, the buried cable from the vibration position to the cable well has no breakage. On the contrary, if the sensing signal in the cable does not change during vibration, the cable has a breakage point;

After determining the actual breakage point, energize the cable well at the actual fault point again, and determine the detection route according to the continuity of the municipal electrical equipment;

Repeat the above steps for all cable wells on the inspection route to determine all actual breakage points, and then determine the actual breakage section according to all actual breakage points to complete the inspection.

Beneficial effects of this program:

Not only can the fault point in the cable breakage area be accurately obtained, but also the damaged section can be determined according to the fault point; and when multiple fault points occur, all the damaged sections can be determined accordingly, so that there is no need to The excavation and repair of the entire damaged section of the buried cable only requires targeted repair of all the specific damaged sections of the municipal buried cable; it not only improves the detection effect, but also indirectly improves the cable repair efficiency, reducing the Time and labor costs required to repair cables.
