Description

The present invention relates to an abnormality detection system for a pole article that detects an abnormality in various devices installed in a utility pole or a utility pole.

Various types of equipment (hereinafter referred to as “posts”) are installed on a utility pole that supports electric wires and a telegraph pole that supports telephone lines. For example, in the case of a utility pole, a switch that separates distribution lines in the event of a power outage, a transformer that converts high voltage into low voltage and supplies it to a lead-in line, etc. are installed as poles. Since such power poles are installed in a wide range for electricity transmission and distribution, information such as switches and transformers is centrally managed by the management system in response to power outages and lightning strikes. As this management system, for example, an IC tag with a built-in current sensor is attached to a steel frame of a steel tower that supports a transmission line. The center of the management system manages lightning strikes based on the current value detected by the current sensor of the IC tag. In this way, an IC tag incorporating various sensors is provided in a switch or transformer, and the state of the switch or transformer is detected by the sensor, so that the management system manages the switch or transformer ( For example, see Patent Document 1.)

IC tag _{40IC k, 41IC k ~46IC k,} 51IC k, 52IC k, since all the 61IC _k ~66IC _k have the same structure, illustrating the IC tag 41IC _k provided on the insulator 41 _k (Fig. 2) as an example To do. As shown in FIG. 4, the IC tag 41IC _k includes an antenna 41A and a control unit 41B. Antenna 41A receives an electromagnetic field transmitted from the reader 10 _k. Then, the antenna 41A supplies the received electromagnetic field power to the control unit 41B. The controller 41B is formed of a semiconductor integrated circuit. Such a control unit 41B has a memory function and stores in advance a management number, which is identification information for identifying a mounted article. The control unit 41B operates when receiving power supply from the antenna 41A by an electromagnetic field, reads a management number stored in advance, and transmits the management number from the antenna 41A by an electromagnetic field.

The reading devices 10 ₁ to 10 _n are installed on top of the utility poles 100 _{1 to} 100 _n . Since the readers 10 ₁ to 10 _n all have the same structure, an arbitrary reader 10 _k (FIG. 4) will be described. The reading device _10k includes an antenna 11 and a device main body 12, and the device main body 12 includes a reading unit 12A and a power line communication unit 12B.

The reading unit 12A has a memory function, and by using this memory function, the utility pole number of the utility pole 100 _k (FIG. 2) where the reading device 10 _k is installed is stored in advance. The utility pole number is a management number of the utility pole, and is identification information given to identify each utility pole.

When the reading unit 12A receives a reading signal from the electric station via the power line communication unit 12B, the reading unit 12A performs a reading process. That is, the reading unit 12 </ b> A compares the management number (electric pole number) of the utility pole included in the received read signal with the management number (electric pole number) of the utility pole stored by the memory function. When the two control number (utility pole number) match, the reading unit 12A, IC tag 40IC _k provided in the utility pole 100 _k and KakuSohashira _{thereof, 41IC k ~46IC k, 51IC k} , 52IC k, 61IC k ~ The electromagnetic field for reading the management number from 66 IC _{k is} transmitted from the antenna 11. At this time, the strength of the electromagnetic field transmitted from the antenna 11 is preset in the reading unit 12A. That is, as shown in FIG. 5, the reading range A by the reading unit 12A of the reader 10 _k is, IC tag 40IC _k provided in the utility pole 100 _k and KakuSohashira _{thereof, 41IC k ~46IC k, 51IC k} , 52IC _k, to include 61IC _k ~66IC _k, the output intensity of the electromagnetic field is set. As a result, for example, a transformer 52 _k from falling out the utility pole 100 _k, since out of the range A read IC tag 52IC _k of the transformer 52 _k, that is, the electromagnetic field reaches for reading the identification information from the IC tag 52 _k since the range of, reading unit 12A of the reader 10 _k can not read the management number from the IC tag 52IC _k.

  When the reading unit 12A receives the management number from the IC tag by the electromagnetic field before the predetermined time has elapsed after the transmission of the electromagnetic field, the reading unit 12A sets all the received management numbers as response signals. Then, the reading unit 12A sends a response signal to the power line communication device 21 at the electric station (FIG. 1) using the power line communication unit 12B.

The power line communication device 21 in the electric station (FIG. 1) performs data communication with the readers 10 ₁ to 10 _n installed in the utility poles 100 _{1 to} 100 _n using the electric wire 110 for sending electric power. The communication control device 22 performs data communication with the sales office via the communication network NW. That is, when receiving the read signal from the sales office, the communication control device 22 sends the read signal to the reading devices 10 ₁ to 10 _n through the electric wire 110 using the power line communication device 21. Further, when receiving a response signal from the power line communication device 21 with respect to the read signal, the communication control device 22 sends this response signal to the sales office via the communication network NW.

  The communication control device 31 of the sales office (FIG. 1) performs data communication with the communication control device 22 of the electric office via the communication network NW. That is, when the communication control device 31 receives the read signal from the management server 32, the communication control device 31 transmits the read signal to the communication control device 22 at the electric station via the communication network NW. Further, when the communication control device 31 receives a response signal from the communication control device 22 at the electric station via the communication network NW, the communication control device 31 sends the response signal to the management server 32. The terminal 33 is a computer operated by a person in charge at the sales office, displays various types of information managed by the management server 32, and prints and outputs the information.

The management server 32 is a computer that manages the poles installed in the utility poles 100 _{1 to} 100 _n . In other words, the management server 32 manages whether or not the pole post is installed at a normal position with respect to the utility poles 100 _{1 to} 100 _n . For this purpose, the management server 32 stores the conversion table and the management table in the database 32A. The conversion table represents the relationship between the management number (electric pole number) of each utility pole and the poles installed on the utility pole. This conversion table is shown in FIG. The conversion table in FIG.
Management number (telephone pole number) of the utility pole 100 ₁ “0001”
Utility pole 100 ₂ of the control number (telephone pole number) ... "0002"
...
100 _n management number (electric pole number)… “N”
As shown, different management numbers (electric pole numbers) are recorded corresponding to the respective electric poles. As described above, the management number (electric pole number) is identification information for identifying the electric poles 100 _{1 to} 100 _n . In addition, any utility pole 100 _k (FIG. 2) has a
Isogo 41 IC _k ... “No. 1 Isogo”
...
Isogo 46 IC _k ... "No. 6 Isogo"
Switch 51 _k ... "Switch"
Transformer 52 _k “Transformer”
Electric wire 110 (R phase) ... "R phase wire"
Electric wire 110 (S phase) ... "S phase wire"
Electric wire 110 (T phase) ... "T phase electric wire"
Is recorded in the conversion table, and
Management number of “No. 1 lion”… “00101”
...
Management number of “No. 6 lion”… “00106”
Management number of “switch”… “00107”
“Transformer” management number… “00108”
"R phase wire" ... "00109"
"S phase wire" ... "00110"
"T-phase wire" ... "00111"
In this way, different management numbers are recorded corresponding to the columns. As described above, the management number is identification information for identifying the pillar. In the following, the conversion table shown in FIG. 6 is used as the conversion table.

  With such a conversion table, it is possible to identify the utility poles and the poles installed on the utility poles by using the pole management number (the pole number) and the pole management number.

  The management table indicates whether or not the columnar article is in a normal installation position or an abnormal position, and this management table is shown in FIG. In the management table of FIG. 7, along with the date, when the poles installed on each power pole are in a normal installation position, the value “1” is recorded as information indicating that the pole poles are normal, In addition, when the columnar object cannot be confirmed, that is, when the columnar object is in an abnormal position, a value “0” is recorded as information indicating that it is abnormal. Information of such values “1” and “0” is updated by the management process described below.

The management server 32 performs management processing to detect whether the poles of the utility poles 100 _{1 to} 100 _n are in a normal installation position or an abnormal position. When the management process is started, as shown in FIG. 8, the management server 32 refers to the conversion table (FIG. 6) and selects the management number (telephone number) of the utility pole (step S1). After step S1, the management server 32 uses the communication control device 31 to transmit, as a read signal, an instruction for reading the management number of the utility pole and the pole and the management number (electric pole number) selected in step S1. (Step S2). After step S2, the management server 32 waits for a response signal from the communication control device 31 (step S3).

  When receiving the response signal in step S3, the management server 32 takes out the management number of the utility pole (electric pole number) and the management number of the poled article included in the response signal (step S4). After step S4, the management server 32 uses the conversion table (FIG. 6) of the database 32A to identify the utility pole and poles corresponding to the management number (step S5), and the management number of the utility pole identified in step S5. Based on the (electric pole number) and the management number of the pole article, the state of the pole article is recorded in the management table (FIG. 7), and the detection result of the utility pole and pole article is stored in the database 32A (step S6). At this time, the management server 32 records the value “1” for the utility poles and poles that can be identified in step S5, that is, the poles and poles whose management number can be read from the IC tag. The value “0” is recorded for the utility pole and the pole piece whose management number could not be read from the IC tag.

  When step S7 ends, the management server 32 checks whether a predetermined time set in advance has elapsed (step S7). As described above, the predetermined time is a time when all the IC tags of the utility poles are expected to send a response signal in response to the read signal, and is set in the management server 32 in advance. If it is determined in step S7 that the predetermined time has elapsed, the management server 32 refers to the conversion table (FIG. 6) to check whether there is an unselected telephone pole number (step S8). If there is no unselected telephone pole number in step S8, the management server 32 ends the management process.

  On the other hand, if the predetermined time has not elapsed in step S7, the management server 32 returns the process to step S3, and if there is an unselected telephone pole number in step S8, the management server 32 returns the process to step S1.

  As described above, when the management server 32 performs the management process, a list of IC tags that have sent a response signal to the read signal is recorded in the management table of the database 32A. That is, the IC tag that has sent the response signal is stored in the database 32A as an IC tag at a normal installation position, and the IC tag that has not sent a response signal is stored in the database 32A as an IC tag at an abnormal position. Thereafter, when receiving the inquiry signal from the terminal 33, the management server 32 refers to the management table (FIG. 7) of the database 32A, reads out the utility pole and the polework at the abnormal position, and sends them to the terminal 33.

Next, a method for detecting an abnormality in a pillar using the abnormality detection system for a pillar according to this embodiment will be described. In the sales office, the management server 32 executes management processing at predetermined intervals according to an instruction from the terminal 33. With this management processing, the management server 32 transmits a read signal to the electric station via the communication network NW using the communication control device 31. The electric station, the communication control device 22 is read to receive the signal, the power line communication apparatus 21 transmits the read signal to the reader ₁₀ 1 to 10 _n of the utility pole ₁₀₀ 1 to 100 _n by way of the wire 110. When the power line communication unit 12B of the reading devices 10 ₁ to 10 _n receives the reading signal, it sends this signal to the reading unit 12A. When the reading unit 12A receives the reading signal, it performs a reading process, and compares the telephone pole management number (electric pole number) stored in advance with the telephone pole management number (electric pole number) included in the reading signal.

For example, when in the reading device 10 ₁ of the utility pole 100 ₁ for storing telephone poles management number (utility pole number) "0001" two numbers match, the reader 10 ₁ of the reading unit 12A is provided in the utility pole 100 ₁ An electromagnetic field for reading the management number from the IC tags 41IC _{1 to} 46IC ₁ , 51IC ₁ , 52IC ₁ , 61IC _{1 to} 66IC ₁ provided in the respective columns of the IC tag 40IC ₁ and the electric pole 100 ₁ is provided to the antenna 11 Send from. Thereafter, the reading section 12A of the reader 10 ₁ receives the control number from the IC tag by the electromagnetic field, and the control number and the response signal, and sends a response signal to the substation with the power line communication unit 12B. At the power station, when the power line communication device 21 receives the response signal, the communication control device 22 transmits the response signal to the sales office via the communication network NW.

  In the business office, when the communication control device 31 receives the response signal, it sends this signal to the management server 32. The management server 32 records the state of the utility poles and poles in the management table based on the pole number management number (the pole number) and the pole number management number included in the response signal by the management process. That is, the IC tag that has sent the response signal is stored in the database 32A as an IC tag at a normal installation position, and the IC tag that has not sent a response signal is stored in the database 32A as an IC tag at an abnormal position. Thereafter, when the person in charge operates the terminal 33 to send an inquiry signal to the management server 32, the management server 32 refers to the management table (FIG. 7) of the database 32A, and the utility pole and the mounting pole at the abnormal position. The object is read and sent to the terminal 33. The terminal 33 displays and outputs the utility pole and polework at the abnormal position.

As described above, according to this embodiment, when the utility pole falls or the utility pole is dropped, the management number is not received from the IC tag. It is possible to detect whether is in a normal installation position or an abnormal position. Similarly, according to this embodiment, it is possible to detect whether the utility pole is in a normal installation position. Furthermore, according to this embodiment, since data communication is performed using the electric wire 110, it is not necessary to newly install communication equipment for the reading devices 10 ₁ to 10 _n .

Unmanned helicopter HE equipped with such a reader 81 and wireless communication device 82, when flying from the communication device 90 receives the read signal, when flying to the top of any pillar 100 _k, the utility pole 100 _k and Sohashira product IC tag _{40IC k, 41IC k ~46IC k,} 51IC k, 52IC k, to send an electromagnetic field in order to read the control number from 61IC _k ~66IC _k. Thereby, the reading device 81 reads the management number from the IC tag within the reading range A. That is, the reading device 81 of the unmanned helicopter HE is connected to the utility pole as in the case where the reading devices 10 ₁ to 10 _{n of the first} embodiment read the management number from the IC tags of the utility poles 100 _{1 to} 100 _n and transmit a response signal. The management number is read from the IC tags 100 _{1 to} 100 _n and response signals are transmitted.

Thus, by this embodiment, as in the first embodiment, it may fall utility pole 100 _k, but also, when Sohashira of the utility pole 100 _k is or fall off and does not receive the control number from the IC tag, It is possible to detect whether the pillar is in a normal installation position. Moreover, since the positions of the utility poles 100 _{1 to} 100 _n are set in advance in the unmanned helicopter HE, the utility pole is inclined depending on whether the management number (electric pole number) of the IC tag provided on the utility pole can be read. It can be detected whether or not.
