Description

Method and System for monitoring power line

The present invention relates to a method and system for monitoring a power line, and more particularly, to a method and system for monitoring a power line by determining whether the current line of the power line supported by the telephone poles and whether or not sagging (tilt).

Telegraph poles guide power lines to places where electricity is needed, such as homes and businesses, while supporting power lines that supply electricity to power plants and substations. By the way, since the electric power line has a relatively high voltage, it may be shorted through the telephone pole which is an insulator. Therefore, in order to minimize this possibility, the power line is not directly contacted with the telephone pole, and the power line is fixed through the connector having excellent insulation.

In addition, identification symbols B1 to B6 located on the line 1 42 are galvanic sensors for detecting the current flowing in the line 1 42. The identification symbols C1 to C6 located on the line 2 44 are galvanic sensors for detecting the current flowing in the line 2 44. The identification symbols D1 to D7 located on the line 3 46 are galvanic sensors for detecting the current flowing in the line 3 46. Here, the galvanic sensors B1 220, C1 240, and D1 260 installed at the lines 1, 2, 3 (42, 44, 46) are header node sensors of the respective lines based on the proximity to the gateway 300. . Accordingly, the sensors installed in each of the support lines 30 and the lines 42, 44, and 46 are informed to the gateway 300 through the galvanometer sensors B1 220, C1 240, and D1 260, which are header node sensors.

As shown, the sensor network is a tilt sensor (A1, ..., A6) is installed in the support line 30, galvanic sensors (B1, ..) installed in the lines 1, 2, 3 (42, 44, 46). ., B6, C1, ..., C6, D1, ..., D6), and gateways 300, 300a installed in the telephone pole.

Each of the inclination sensors and the galvanometers establishes an optimal routing path to the gateways 300 and 300a through a neighbor search process. Tilt sensors and galvanometers set the optimal path in consideration of the signal strength and the path distance. Gradient sensors and galvanometers are unique sensor identification information including gate identification information (GW_ID), line type identification information (Line Type ID), and sensor node identification information (Sensor Node ID) through a neighbor search process. ID). The unique sensor identification information is registered and stored in the line monitoring server 500.

Meanwhile, when an error occurs in the sensor node or the gateway, the path detour setting method of the sensor is as follows. That is, in the present embodiment, in order to bypass the routing path of the sensor, the neighboring sensor network may be used or the routing path in the sensor network may be reset according to whether the neighboring sensor network is used.

6 is a diagram illustrating an example of sensor registration and routing setting when a sensor is added in the power line monitoring system according to an exemplary embodiment of the present invention.

As shown, when a new galvanometer sensor 270 is added to line 3 46, the additional galvanometer sensor 270 indicates that it has been added to the sensor network with neighboring node sensors C6 242 and D7 262 and the gateway. Broadcast to 2 (300a).

The neighbor node sensors C6 242 and D7 262 transmit the received broadcast message to their gateway 2 300a through their default router.

Receiving the broadcast message received from the sensors C6 242 and D7 262, the gateway 2 300a selects the received message at the minimum cost, and selects the gateway identification information GW_ID and the line type identification information Line Type_ID. And broadcasts a prefix through the group header node sensor of the corresponding line.

The additional galvanometer 270 generates its own unique sensor ID and sets basic routing by using the prefix information in the received advertisement message.

Thereafter, the gateway 2 300a notifies the neighbor gateway that the new node sensor has been added under its management, and the neighbor gateway deletes the list for the new node sensor.

In this embodiment, the sensors on the track should have the same value within the error range. Data measured at each node sensor may transmit an incorrectly measured value according to a malfunction of the node sensor. In this case, the central track monitoring server 500 generates an alarm that the track is abnormal. In order to determine whether the measured data is malfunctioning, the line monitoring server 500 requests information transmission from neighbor sensor nodes having the same line type as the corresponding node sensor, and compares the received measured value with the initially received measured value. If it is within the margin of error, the information is trusted. In addition, if the line monitoring server 500 is out of the error range and the other request the information transfer to the node again and transmits the same wrong information is determined to be the abnormal node.

On the other hand, the meaningful position information in the line monitoring system of the present embodiment is position information of the line. Therefore, it is not necessary to know the exact location information of each node sensor. In order to find out which track the node sensor is located on, the location information using the satellite navigation (GPS) module of the gateway 300 is used. The gateway 300 has accurate position information through the satellite navigation module and also has a function of assigning a line type of the node sensor. Accordingly, the line monitoring server 500 may determine which line belongs to the node using the unique identifier (Global Unique ID) of the node sensor.
