Description

{System and Method for tracking stolen Copper Wire Cable}

The present invention relates to stolen power line tracking technology. More specifically, it utilizes low-power Bluetooth (Bluetooth Low Energy (BLE)) technology and Ultra Wide Band (UWB) technology to determine whether wire theft has occurred immediately upon occurrence of the incident. and a stolen power line tracking system and method that can be tracked.

In Korea's low-voltage distribution system, three-phase 380V for power and single-phase 220V for home use are supplied from pole-mounted transformers to consumers in a three-phase, four-wire system. Copper is mainly used as the core wire of this low-voltage distribution line. Thefts involving unauthorized theft of distribution lines to obtain this copper occur every year. In particular, thefts of power lines supplied for agricultural purposes occur frequently in mountainous and rural areas where people rarely travel and where supervision is neglected.

Recently, as more solar power complexes are built in mountains or rural areas, power line theft incidents are also increasing. In general, in the 10 years since 2011, about 3,600 cases of 1,700 km of wires were stolen, and the damage amounted to about 3.4 billion won.

In order to prevent such wire theft, aluminum wires are used for new lines, and many systems have been developed and applied to automatically notify that wire theft has occurred, but there is no system in place to track stolen wires. When wire theft occurs, it is limited to reporting it to the police and requesting that they track down the wire and the thief.

Accordingly, even if a wire theft incident occurs, it takes a lot of time to find the stolen wire, apprehend the thief, and receive compensation for the damage, and if the thief is not caught, the power line owner or power company has to bear the brunt of the damage.

In addition, the systems installed to prevent wire theft are made up of various sensors and devices, and most require separate wired/wireless communication lines, so they are not economical.

Referring to FIG. 8, the stolen power line tracking system 800 is installed on the power line 101-1, which is one of a plurality of power lines 101-1, 101-2, and 101-3, so that the power line 101-1 is located by theft. A stolen power line tracking device 120-1 that generates location tracking information when there is a change, a plurality of communication terminals 810 located within a certain distance from the stolen power line tracking device 120-1 and receiving location tracking information, a plurality of A mobile communication network 820 connected to communication with the communication terminal 810, and a mobile communication network 820 connected to the communication terminal 810 to receive location tracking information and alarm information about the stolen power line 101-1 It may be configured to include a tracking management server 130 that generates.

The communication terminal 810 includes a mobile phone, smart phone, laptop computer, digital broadcasting terminal, PDA (Personal Digital Assistants), PMP (Portable Multimedia Player), navigation, note pad, etc. However, it is not limited to this and can be applied to any device that implements BLE and UWB connectivity technology.

The mobile communication network 920 includes CDMA (Code Division Multiple Access), WCDMA (Wideband Code Division Multiple Access), Wibro (Wireless Broadband), WiFi (Wireless Fidelity), HSDPA (High Speed Downlink Packet Access) network, Bluetooth, It may be a Near Field Communication (NFC) network, a satellite broadcasting network, an analog broadcasting network, or a Digital Multimedia Broadcasting (DMB) network.

If the GPS location (latitude, longitude) has changed, track the stolen wire by broadcasting a signal at set time intervals using BLE and UWB connectivity technology and attempt to communicate with the surrounding communication terminal 810. do.

In detail, the stolen wire tracking device 120-1 broadcasts a signal to the surrounding area for communication with the communication terminal 810, and any nearby communication terminal 810 transmits the signal of the stolen wire tracking device 120-1. A mutual communication connection is established. That is, the BLE module 320 and the UWB (Ultra Wide Band) module 340 are activated and communication is attempted with the external communication terminal 810 at a set time period.

Therefore, the stolen wire tracking device 120-1 sends GPS information of the current location along with the device ID (MAC address) unique to the tracking device to any communication terminal 810 and the mobile communication network that the communication terminal 810 is using ( It is transmitted to the remote tracking management server 130 through 920).

In contrast, the stolen wire tracking device (120-1) is normally attached to the power line in sleep mode without GPS measurement to reduce power consumption, and then detects Bluetooth signals in the surrounding area within a certain distance (within a radius of approximately 200 m) (801). It is activated by a communication connection request, and from then on, GPS information is acquired at set time intervals and the measurement time and GPS positioning are stored. Afterwards, it attempts to connect to any nearby communication terminal 810 using a compatible OS (Operating System) and application using BLE and UWB.

For connection between the BLE/UWB module of the stolen wire tracking device and the communication terminal, the application of the communication terminal can simultaneously activate the BLE and UWB settings supported by the terminal. By using BLE and UWB at the same time, location determination can be mutually complemented, and through this, the distance to the stolen wire tracking device can be measured in various environments such as short distances, LOS (Line-Of-Sight) areas, and dense areas where multiple reflected waves occur. Precision can be increased.

When a communication terminal with a built-in BLE or UWB module approaches (up to 100m), the stolen wire tracking device communicates with the device via BLE/UWB. At this time, the BLE or UWB module of the communication terminal measures the distance to the stolen wire tracking device. For this purpose, a method of calculating the distance in proportion to the intensity of the transmitted wave (Received Signal Strength Indication, hereinafter referred to as RSSI) is used.

Figure 9 is a flowchart showing the process of displaying on the screen and generating alarm information according to another embodiment of the present invention. Referring to FIG. 9, the tracking management server 130 is connected to the communication terminal 810 and the mobile communication network 820 (step S910).

Thereafter, the communication terminal 810 transmits the ID (MAC address) information and location tracking information received from the stolen power line tracking devices 120-1, 120-2, and 120-3 to the tracking management server 130 (step S920).

Thereafter, the tracking management server 130 compares the information stored in the database (not shown) with the received information and, if different, determines whether there is an error in the location tracking information (step S930).

As a result of the confirmation, if it is different from the data stored in step S930, the movement path on the screen is displayed and alarm information is generated and provided to the user (step S940).

On the other hand, if the confirmation result is the same as the data stored in step S930, the process proceeds to the previous step S920.
