Hereinafter, a remote pipe inspection system according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 to 5, in the remote pipe inspection system proposed by the present invention, a plurality of remote detection devices 1 are connected to a pipe (L) buried underground, and real-time potential values of the pipe (L) are connected. By measuring with and transmitting to the external server (S), it is possible to grasp the state of the pipe (L) in real time, and also detect the impact of surroundings by the vibration sensor (17) or the hall sensor (18) to determine whether or not excavation work. It is easy to grasp.

The remote pipe reading device 1 will be described in detail.

A case (3,5) forming an exterior; A PCB panel (PCB Pannel) 15 mounted inside the cases 3 and 5 to measure a potential value; A modem connected to the PCB panel 15 and transmitting a signal to the outside (Modem; 13); A vibration sensor 17 connected to the PCB panel 15 and detecting vibration transmitted to the cases 3 and 5; A hall sensor 18 connected to the PCB panel 15 and sensing magnetic force; It includes a battery 11 for supplying power.

The case (3,5) is composed of the upper and lower parts are coupled in an assembly manner by bolts or the like.

Of course, other structures are possible in addition to the cases 3 and 5.

And, the PCB panel 15 is an electronic circuit for controlling the remote pipe reading device 1 and measuring a potential difference, and two cables 7 and 9 are connected to the outside through the lower part of the cases 3 and 5 Is extruded. Of these two strands of cables 7 and 9, one strand 7 is connected to the surface of the pipe L, and the other one strand 9 is connected to the ground point E of the ground and is grounded. .

Therefore, the PCB panel 15 can measure the potential value of the pipe L by passing a predetermined current through the cable 7 and 9 to the pipe L.

Then, the measured potential value may be transmitted to an external server S or a mobile communication device through the communication modem 13.

The communication modem 13 may be applied to various types of communication modems, for example, IOT modem 13, Bluetooth (Blue tooth), WiFi, or eggs (egg) in a communication environment such as 3G, 4G, etc. It can be connected to an external communication device (M) through.

Then, the vibration sensor 17 detects vibrations generated in the cases 3 and 5 and transmits a signal to the PCB panel 15. The PCB panel 15 that receives the vibration signal is in a wake-up state, and turns on the power of the Bluetooth circuit.

In addition, the Bluetooth signal is transmitted to the outside and is interlocked with a mobile communication terminal (M) such as a smartphone possessed by an operator.

Therefore, the operator can grasp the potential difference of the remote pipe reading device on the terminal.

The vibration sensor 17 may include various types of sensors, for example, a moving coil-type vibration sensor or a fiber-optic vibration sensor. .

The movable coil type vibration sensor has a structure in which a magnetic circuit is created to generate a uniform magnetic field in a narrow gap by a strong magnet, and the coil that can move perpendicular to the magnetic flux is fixed to the diaphragm. Therefore, when the diaphragm vibrates, electromotive force is generated in the movable coil according to Fleming's right-hand rule, which is converted into an electrical signal to detect vibration.

The fiber optic vibration sensor is a fiber optic sensor that measures vibration and converts it into a change in light intensity or reflected intensity of light to detect it.

In detail about the operation process of the vibration sensor 17, when the operator wants to check the state of the pipe L, activates the related app of the smartphone M he has, loads, etc. The case (3,5) is tabbed using the mechanism of.

In this way, when the shock is generated by the load of the cases 3 and 5, the vibration sensor 17 detects this and transmits a signal to the PCB panel 15.

The PCB panel 15 receives this signal, becomes a wake-up state, and turns on the power of the Bluetooth circuit.

And, the Bluetooth signal is transmitted to the smart phone (M) carried by the worker, it is possible to grasp in real time information such as the potential value or state of the pipe (L) on the activated app.

In addition, when a plurality of remote pipe metering devices 1 are connected to the pipe, when a specific remote pipe metering device 1 is used to wake up by generating a shock using a rod, the neighboring remote pipe metering device 1 It can be woken up by the vibration wave caused by this shock.

Therefore, in order to prevent this, the PCB panel 15 is equipped with an amplifier and a filter, so that the vibration below the reference value is controlled so as not to wake up.

At this time, LNA (Low Noise Amplifer) is used as the amplifier, and BPF (BandPass Filter) is applied as the filter.

Therefore, the vibration transmitted from the neighboring remote pipe reading device 1 can be prevented from being malfunctioned by being divided by these amplifiers and filter devices to be smaller than the reference vibration value.

In the above, a method of measuring a potential value by generating vibrations in the cases 3 and 5 by a rod is described, but the present invention is not limited thereto, and a magnetic force method is also applicable.

That is, when the magnet is in contact with the cases 3 and 5, the hall sensor 18 provided inside the cases 3 and 5 reacts with the magnetic force of the magnet to generate a signal.

The Hall sensor 18 is a sensor that detects geomagnetism due to a Hall effect. As the electron is deflected by a current and a magnetic field in an orthogonal conductor, a voltage is generated across the conductor. Voltage) is a way to know the size of the magnetic field that is currently incident.

In more detail, when the operator wants to check the state of the pipe L using the hall sensor 18, the related app of the smartphone M in possession is activated, and a rod equipped with a magnet is loaded. ) Tabs the cases 3 and 5 using a mechanism such as.

When the rod is in contact with the cases 3 and 5, the magnetic field is transferred by transferring the magnetic force inside the cases 3 and 5, and the hall sensor 18 detects this and transmits a signal to the PCB panel 15.

The PCB panel 15 receives this signal, becomes a wake-up state, and turns on the power of the Bluetooth circuit.

And, the Bluetooth signal is transmitted to the smart phone (M) carried by the worker, it is possible to grasp in real time information such as the potential value or state of the pipe (L) on the activated app.

In addition, the magnetic force sensing method is controlled to prevent wakeup when the magnetic field is less than a reference value by mounting an amplifier and a filter having a magnetic field value input to the PCB panel 15 in the same manner as the vibration method.

In addition, the vibration sensor method and the hall sensor method may be applied at the same time, so the vibration sensor is primarily operated, and the hall sensor may be operated secondary. That is, when the vibration sensor is operated by tapping the rod into the case, but it is not wake-up, the hall sensor is operated.

On the other hand, the above has been described with respect to the invention in which the operator checks the potential difference by the terminal having access to the remote pipe reading device, the present invention is not limited to this, and the impact or damage to the pipe L due to the excavation work When this occurs, it can also be detected in real time.

That is, as illustrated in FIG. 3, a plurality of remote pipe reading devices 1 are installed at regular intervals in the pipe L buried in the ground. At this time, the remote pipe reading device 1 is buried in a closed state by the withdrawal 2.

In this state, when an impact occurs due to the excavation work at a predetermined position, the vibration propagates through the pipe L to all sections.

And, this vibration is first reached to the remote pipe reading device 1 closest to the place where the impact occurred, and the vibration sensor 17 detects it.

Then, the vibration sensor 17 transmits a signal to the PCB panel 15, and the PCB panel 15 receives this signal to be in a wake-up state.

Then, the communication modem 13 transmits vibration signals and data to the outside, and the server S of the central control station at a remote location receives this signal. At this time, the vibration data includes location coordinates of the point where the vibration occurred, and information about the intensity of the vibration.

Therefore, in the central control center, vibration has occurred at the corresponding position, and it is possible to grasp in real time how much vibration intensity it is and take necessary measures.

At this time, a GPS device is attached to the remote pipe reading device 1. Therefore, the server S of the central control center can recognize the exact coordinates of the point where the vibration occurred by the GPS signal.

This GPS signal can be applied not only to confirm the location where the vibration has occurred, but also to confirm the current location when the remote pipe reading device 1 is lost.

That is, since the lost remote pipe reading device 1 continuously transmits a GPS signal, an operator can detect and recover the current location by detecting the corresponding GPS signal.
