1 and 2, the underground pipe 10 is formed in the form of a rectangular box having an internal space that an operator can enter and maintain. A base 20 having a predetermined width and height is provided on the bottom surface of the receiving space 11 for receiving the underground distribution line L of the underground pipe 10. A support 21 is vertically provided at the center of the base 20 And at the same time, a box-shaped control unit 50 is provided on one side of the upper end of the support 21. The control unit (50) and the support base (21) are connected to each other.

A plurality of unit underground distribution lines L 1, L 2, ..., L 8 are arranged on the upper surface of each shelf 30 in a predetermined interval and width, Respectively. These underground distribution lines L are held on the upper surface of each shelf 30 in a state where they are mounted in the seating grooves 301 formed in the longitudinal direction.

The underground distribution line L may be arranged so that the flow thereof is interrupted when it is mounted on the shelf 30. 1, the seating groove 301 formed in the shelf 30 is formed to be deeper than the radius R of the applied underground distribution line L so that at least 1/2 of the outer circumferential surface of the ground distribution line L is mounted in the seating groove 301 The operator can apply a constant force to the underground distribution line L and fix it in a forced fit manner.

A sensing panel 40 is mounted on the lower side of each of the shelves 30 and a surface of the sensing panel 40 in contact with the shelf 30 corresponds to a seating groove 301 formed in the longitudinal direction of the shelf 30 A plurality of sensors are disposed in the position. The sensor is preferably a photosensor S and the photosensor S has a general configuration in which a light-emitting portion (light-emitting portion) and a light-receiving portion are provided together.

The optical signal output from the light emitting portion of the photo sensor S is reflected on the surface of the object or underground distribution line L and received by the light receiving portion. That is, the case where the light receiving unit of the photo sensor S does not receive the optical signal output by the light emitting unit.

The photosensor S preferably emits and receives an optical signal of any one color selected from among the representative seven colors of infrared, ultraviolet, or rainbow.

Accordingly, it is preferable that the shelf 30 is made of a transparent synthetic resin, or at least only the portion where the photosensor S is disposed is made of a transparent material. Or the shelf is formed of a metal material, the corresponding position of the photosensor S described above may be formed as an open hole.

The control unit 50 is fixed to the upper portion of the underground pipe 10 so as to occupy the safest position when the inside of the underground pipe 10 is submerged. The control unit 50 is electrically connected to the sensing panel 40 provided in correspondence with each shelf 30 and is connected to the underground pipe 10, the shelf 30, It is possible to read information on the abnormality of the underground distribution line L and to transmit the information on the ground to the worker wirelessly.

Referring to Fig. 3, the support 21 has a hollow portion 211 in the form of a pipe. The electrical lines of the sensing panel 40 fixed to the support 21 are connected to the control unit 50 through the hollow portion 211 of the support 21. That is, the complication of the external wirings is eliminated and the malfunction of the control unit due to flooding is prevented in advance.

Accordingly, when a specific ground distribution line L, which may occur due to a natural disaster such as an earthquake or a ground erosion, and the position of the shelf 30 is changed, the photosensor S disposed at the lower side thereof performs a sensing operation To the control unit 50. The control unit 50 is capable of transmitting the abnormal information of the underground distribution line L to the ground operator.

4 is a block diagram showing the relationship between the sensing panel 40 and the control unit 50 shown in Fig. 4, the control unit 50 includes a control unit 51, an abnormal position determination unit 52, and a wireless transmission unit 53. [

The abnormal position confirming unit 52 receives the detection signal of the corresponding underground distribution line L in which the abnormality occurs among the plurality of photosensors S arranged on the sensing panel 40 and detects the position information of the shelf 30 And provides information of the underground pipe 10 to the control unit 51.

For example, when the underground distribution line L is separated from the seating groove 301 of the shelf 30, the photosensor S of the sensing panel 40 senses it and provides it to the abnormal position determination unit 52. The sensing information may be a concept including positional information of the unit underground distribution line L, positional information of the shelf 30, and unique information of the underground pipe 10. Therefore, the abnormal position determination unit 52 detects the detection signal and provides the control unit 51 with the information of the underground pipe 10, the information of the shelf 30, and the information of the underground distribution line L.

The control unit 51 transmits the abnormal information about the underground distribution line L provided by the abnormal position determination unit 52 by using the wireless transmission unit 53. [ The control unit 51 reads the detection signal for the underground distribution line L provided by the abnormal position determination unit 52 and detects the corresponding position of the underground distribution line L, the corresponding position of the shelf 30, Converts the information into a signal that can be read by the operator, and controls the wireless transmission unit 53 to transmit the signal.

More preferably, the above-described control unit 51 may be a concept including a storage unit. Therefore, it is possible to provide the information of the underground distribution line in which the abnormality is detected by providing the operator with the storage information of various additional information such as the role and function of the underground distribution line L together.

For example, when the sixth underground distribution line L6 of the second shelf R2 of FIG. 1 is detached from the shelf, the corresponding photosensor S of the detection panel 40 installed below the second underground distribution line L6 senses that the underground distribution line is deviated.

For example, the photo sensor S of the sensing panel 40 may include a light emitting portion and a light receiving portion. When a ground distribution line is placed on a transparent material shelf 30, the light source irradiated by the light emitting portion is reflected by the underground distribution line, It will be detected that the underground distribution line is not separated from the corresponding seating groove 301. [

However, when the underground distribution line is detached from the corresponding mounting groove 301, the light receiving part which is irradiated by the light emitting part and received the light reflected by the underground distribution line fails to receive the light source reflected by the deviation of the underground distribution line, To the abnormal position check unit (52) of the control unit (50).

Accordingly, the abnormal position confirming unit 52 confirms the detected position information of the photosensor S and provides the controller 51 with information on the detected position information. The control unit 51 transmits the information (for example, information indicating that an abnormality has occurred in the L6 underground distribution line of the R2 shelf of the Nth underground pipe and the underground distribution line is an extra-high voltage wire provided to the area) to the radio transmission unit 53 To the ground.

Accordingly, an operator working on the ground immediately monitors such monitoring information and determines the position of the underground pipe 10 and the type of the underground distribution line R2 and the underground distribution line L6 in which the underground distribution line L6 is located, High-voltage cables to the area), which can shorten maintenance time and reduce costs.
