The present invention relates to a high-voltage line state monitoring system, and more particularly to a high-voltage line state monitoring system that can predict and prevent danger by monitoring the state of the high-voltage line by using a sensor that operates without power.

In order to measure the temperature and the degree of deterioration due to aging of most switchgears or power facilities, the temperature measurement and the deterioration state were checked by directly projecting on a part to be measured using a separate temperature measuring device or a thermal imaging camera. In most cases, it is only measured periodically based on the specified inspection criteria and only the external appearance condition is estimated by the neck side to estimate the condition. Therefore, there is a problem that it cannot prevent accidents due to the integrity and deterioration of the switchgear or high-voltage line in advance. .

Installing the sensor directly on the high voltage line is very limited due to the need to cut off the current flowing in the high voltage line when installing the sensor, and the lack of a sensor that works well under the harsh conditions of the high voltage line.

In addition, even if the sensor is installed directly, the external power supply for sensing is required, so there is a drawback of regular battery replacement or unnecessary power consumption. In addition, in the case of a sensor operating with no power, there is a disadvantage in that the measured value of the sensor is not accurate when the sensor receives a carrier of too high a strength or a carrier of too weak a strength from the reader.

An object of the present invention is to provide a high-voltage line state monitoring system that can be effectively to monitor the state of the high-voltage line by operating in a non-power source to solve the problems as described above.

The information is analyzed by the same technique as the big data method that extracts the information.

Hereinafter, the operation of the high-voltage line state monitoring system according to the present embodiment configured as described above will be described.

The carrier wave generated by the reader transmitter 220 of the reader unit 200 is transmitted through the reader antenna 100. The temperature tag 10, the moisture tag 20, and the vibration tag 30 are activated by receiving a carrier wave transmitted from the reader antenna 100. As such, the tags 10, 20, and 30 use a carrier wave transmitted from the reader antenna 100 as an energy source, and thus may operate without their own power source. Therefore, there is an effect of minimizing the power used to monitor the state of the high-voltage line (L). In addition, since the wireless unit operates by supplying power, the reader unit 200 and the reader antenna 100 that supply power are electrically disconnected from the tags 10, 20, and 30. The manager may safely maintain and maintain the high voltage line L and the reader unit 200 and the reader antenna 100 electrically disconnected from each other. The tags 10, 20, and 30 may measure temperature, moisture, and vibration using a carrier wave, and may return a value measured using the carrier wave as a response signal. The response signals carried by the tags 10, 20, and 30 are received by the reader receiver 210 of the reader unit 200 through the reader antenna 100.

Meanwhile, an error may occur in a value measured by the tags 10, 20, and 30 according to the strength of the carrier wave. The reader transmitter 220 of the reader unit 200 measures the strength of the carrier wave transmitted to the tags 10, 20, and 30 through the strength of the carrier wave included in the response signal carried by the tags 10, 20, and 30. Adjust Each tag 10, 20, 30 stores the strength of the carrier wave when the correct measurement value is output as the appropriate strength of the carrier wave. The reader unit 200 compares the strength of the carrier wave included in the response signal with the appropriate intensity of the carrier wave. If the strength of the currently transmitted carrier wave is stronger than the appropriate intensity of the carrier wave, the strength of the carrier wave is reduced. On the other hand, when the strength of the currently transmitted carrier wave is weaker than the appropriate strength of the carrier wave, the strength of the carrier wave is increased. As a result, the strength of the carrier wave transmitted to the tags 10, 20, 30 can be maintained at the appropriate intensity of the carrier wave. Through this process, @ has advantages in that the tags 10, 20, and 30 can perform more accurate measurement.

The tags 10, 20, and 30 for measuring temperature, moisture, and vibration can be easily installed by an attachment method. In particular, financial institutions such as banks, and medical institutions such as hospitals, it is important to continue to supply power. In organizations where this continuous power supply is important, it is limited to shut off the power to install the tags 10, 20, 30. In the case of the high-voltage line condition monitoring system according to the present embodiment, the tags 10, 20, and 30 may be easily installed in a required position through a device such as an insulated tong. Therefore, in this embodiment, there is an advantage that can easily install the tags (10, 20, 30) without power off.

In addition, the reader unit 200 and the reader antenna 100 of the present embodiment are installed in the swing door D of the switchgear. Since the door D is separated from the bus bar L through which the high voltage flows, the manager may safely perform the maintenance of the reader unit 200 and the reader antenna 100.

In this state, when the reader unit 200 generates the inquiry signal and transmits it through the reader antenna 100, the tag communication unit of the temperature tag 10, the moisture tag 20, and the vibration tag 30 which received the inquiry signal ( 12, 22, and 32 return the values measured by the sensors 11, 21, and 31 as response signals in the form of RF through the tag communication units 12, 22, and 32. The inquiry signal generated by the reader unit 200 is a signal instructing the tags 10, 20, and 30 to return a response signal. The tags 10, 20, and 30 activated by the carrier wave only return the response signal when the interrogation signal generated by the reader unit 200 is received. The response signal sent by the tags 10, 20, 30 can be identified in various ways. When the tags 10, 20, 30 carry a response signal, the tags 10, 20, 30 can be identified at time intervals to convey them. In addition, the tags 10, 20, and 30 may be identified by including the identification number of the tag in the response signal carried in the RF form. In some cases, the tags 10, 20, and 30 may be identified by using the above two methods. For this reason, it is possible to identify which tag 10, 20, or 30 the response signal received from the reader unit 200 of the high voltage line condition monitoring system according to the present embodiment. So it's easy to see where the problem is.

Meanwhile, since the tags 10, 20, and 30 are installed in different positions, the reader antenna 100 must move to transmit an inquiry signal to all the tags 10, 20, and 30, and to receive a response signal. do. Hereinafter, a process of moving the reader antenna 100 will be described.

The control unit 230 of the reader unit 200 operates the mobile unit 400. The moving unit 420 of the mobile unit 400 having the reader antenna 100 moves up and down along the guide rail 410 of the mobile unit 400. When the moving unit 420 moves along the guide rail 410, the reader antenna 100 installed in the moving unit 420 is also moved up and down. The reader antenna 100 formed in the shape of a bar moves along the guide rail 410, transmits an inquiry signal to adjacent tags 10, 20, and 30, and transmits a response signal returned from the tags 10, 20, and 30. Receive. In addition, the reader antenna 100 also receives a response signal in the form of RF transmitted by the moisture tag 20 and the vibration tag 30. As such, the high-voltage line condition monitoring system according to the present embodiment may transmit an inquiry signal to the tags 10, 20, and 30 installed at various positions through the reader antenna 100 moving along the guide rail 410. In addition, the response signals returned from the tags 10, 20, and 30 installed at various locations may be received.

Since the reader antenna 100 moves along the guide rail 410 in this manner, even if the temperature tag 10, the moisture tag 20, and the vibration tag 30 are additionally installed, the reader antenna 100 may be provided with the tag 10,. 20 and 30 may receive all response signals. Therefore, the high voltage line condition monitoring system according to the present embodiment can easily add tags 10, 20, and 30 as necessary. For this reason, the high voltage line condition monitoring system according to the present embodiment can monitor the state of the high voltage line L through more information.

In some cases, the reader antenna 100 may not receive a response signal in the form of RF transmitted by the specific temperature tag 10, the moisture tag 20, and the vibration tag 30 while the reader antenna 100 moves. have. When the RF signal is not received as described above, when the relative positions of the tags 10, 20, 30 and the reader antenna 100 are finely adjusted, the reader antenna 100 may normally receive the RF signal. . The control unit 230 of the reader unit 200 controls the mobile unit 400 as a reference value when the response signal of the RF type transmitted from all the tags 10, 20, and 30 is normally received. The controller 230 inductively stores the position at which the reader antenna 100 receives the RF response signal, or sets the reference value in such a manner as to receive the positions of the tags 10, 20, and 30 in advance. If the response signal is not normally received even when the reader antenna 100 has reached a position capable of receiving a response signal in the RF form, the controller 230 controls the mobile unit 400 to stop the reader antenna 100. The controller 230 controls the mobile unit 400 to move finely up and down at the position where the reader antenna 100 normally receives the response signal. When the reader antenna 100 receives the response signal through the fine adjustment, the controller 230 controls the mobile unit 400 to move the reader antenna 100 again. Through the above-described process, the high-voltage line state monitoring system according to the present embodiment can continuously receive the RF-type response signal transmitted from the tags 10, 20, 30 to monitor the state of the switchgear.

When the reader unit 200 receives the response signal returned from the tags 10, 20, and 30 through the above-described process, the reader communication unit 240 of the reader unit 200 converts the response signal into temperature, moisture, and vibration information. The conversion is sent to the server unit 300. The server communication unit 310 of the server unit 300 communicates with the reader unit 200 wirelessly to receive temperature, moisture, and vibration information. The received information is stored in the storage 320 of the server unit 300.

The monitor unit 330 of the server unit 300 displays information transmitted from the reader unit 200. The manager may monitor the state of the switchboard at a long distance through the monitor unit 330 of the server unit 300. Since the server unit 300 enables online communication, the manager can monitor the state of the switchboard in real time even through the mobile terminal.

The safety unit 340 of the server unit 300 operates the safety facility through the information transmitted from the reader unit 200. For example, when the temperature rises excessively compared to the normal case, the safety unit 340 determines that a fire has occurred, operates a fire suppression apparatus inside the switchboard, and transmits a fact of occurrence of danger to a nearby fire engine. Through this, the high-voltage line condition monitoring system according to the present embodiment can quickly respond to the risk without the intervention of the administrator.

The analysis unit 350 of the server unit 300 utilizes the information stored in the storage unit 320 to predict or prevent the risk. The analyzer 350 analyzes the information stored in the storage 320 using a big data analysis technique. It is possible to block the risk in advance through the analysis data of the analysis unit 350. For example, you can collect information immediately before a risk occurs and alert the administrator in advance if the temperature, moisture, and vibration information before the risk occurs are similar to the current temperature, moisture, and vibration information. In addition, it is possible to identify the trend of risk occurrence and inform the manager by using seasonal and hourly information. In some cases, it is also possible to analyze more data at once by integrating information of several switchboards in which the high-voltage line condition monitoring system according to the present embodiment is installed.

As mentioned above, although the heat shielding fire prevention screen which concerns on this invention was described as an example, the scope of the present invention is not limited to the structure demonstrated and shown above.

For example, in the above, the high pressure line condition monitoring system including the temperature tag 10, the moisture tag 20, and the vibration tag 30 has been described, but it is also possible to configure the high pressure line condition monitoring system using only the temperature tag. In addition, it is also possible to configure a high pressure line condition monitoring system using only a temperature tag and a moisture tag.

In addition, the foregoing has been described that a total of nine temperature tags 10 are installed, but the number of temperature tags may be variously changed.

In addition, although the above has been described as attaching the temperature tag 10 with an epoxy adhesive, it is also possible to attach the temperature tag with a double-sided tape.

In addition, although the mobile unit 400 has been described as changing the position of the reader antenna 100 in the above, it is also possible to configure a high-voltage line state monitoring system according to the present invention by omitting the mobile unit. In this case, the position or size of the reader antenna can be configured according to the position where the tag is installed. In some cases, the reader antenna may be installed by magnetic attraction. When the reader antenna is configured by the magnetic attraction method, the mounting position of the reader antenna can be easily changed by attaching and detaching the reader antenna.

In addition, the above described that the high-voltage line state monitoring system is installed on the high-voltage line (L) provided in the switchgear having a door (D), but the high-voltage line state monitoring according to the present invention in a variety of facilities equipped with high-voltage line You can install the system.

In addition, while the tags 10, 20, and 30 that received the interrogation signal of the reader antenna 100 have been described as carrying a response signal, the tag not receiving the interrogation signal continues to carry the response signal. It is also possible to construct a high voltage line condition monitoring system according to the present invention.

In addition, although the foregoing has been described and illustrated as configuring one reader antenna 100, it is also possible to configure a plurality of reader antennas.

In addition, the temperature tag 10 described above may be modified as follows. The temperature tag is composed of a conductive line connected to a high voltage line to transmit a temperature, a sensor unit measuring a temperature of the conductive line, and an insulating coating to insulate the conductive line. Unlike busbars in switchboards, high-voltage lines that connect between power transmission towers deliver ultra-high voltage current. If the temperature tag is directly attached to such a high voltage line, the temperature tag may malfunction or be thermally destroyed as time passes. When the temperature of the high voltage line is measured by connecting the high voltage line and the sensor part with a conductive line and measuring the temperature of the conductive line, the distance between the sensor part and the high voltage line is increased to effectively prevent malfunction or breakdown of the sensor part. can do. In addition, even in the case of the temperature tag is installed in the switchboard can be installed a temperature tag avoiding obstacles between the bus bar to which the reader antenna and the temperature tag is attached in the configuration as described above. This installation of a temperature tag effectively prevents interference due to obstacles between the tag and the antenna.

In addition, the foregoing has been described as including the server unit 300, the server unit can be omitted if necessary.
