In particular, it is preferable that the first drive motor 212 is a stepping motor that rotates by a certain angle by an electric pulse signal and stops with high accuracy.

A stepping motor is a motor that has a simple mechanical structure or electronic circuit and rotates one step at a time in synchronization with a pulse signal input to a motor suitable for digital control.

In addition, in the stepping motor, the total rotation angle of the motor is proportional to the total number of input pulses, and the rotational speed of the motor is proportional to the number of input pulses per second (PPS).

The rotational speed of the stepping motor is precisely proportional to the frequency of the pulse signal (= pulse speed), and when the speed of the pulse is fast, it increases rapidly, and when the speed of the pulse is slow, it decreases slowly.

The crack detection sensor uses an ultrasonic sensor to shoot sound waves into a communication line and detects whether or not there is a crack by calculating the distance between the sound waves reflected and collected.

The crack detection sensor is a sensor that measures the distance using ultrasonic waves, and is composed of a transmitter and a receiver. The transmitter is a function generator that alternately applies a'+' voltage to a'-' voltage to the piezoelectric element due to deformation of the piezoelectric element. Vibration occurs, and an ultrasonic wave is generated by the vibration.

The receiving unit may calculate the distance by measuring the reflected and returning time using a static piezoelectric phenomenon in which the ultrasonic wave is transmitted to the communication line and then reflected and returned by a wave, and a voltage is generated by the vibration.

In other words, the crack detection sensor detects the part where the crack has occurred when the pre-stored time is not measured, as the time for returning the transmitted ultrasonic waves to the uniform communication line is measured equal to the pre-stored time.

It is transmitted to an external manager terminal.

The image information receiving unit 320 receives image information photographed by a camera 170 that is formed in front and rear of the body and photographs a communication line.

In addition, the crack detection information receiving unit 330 receives crack detection information that the crack detection sensor detects as a part where a crack has occurred using ultrasonic waves.

The control unit 360 collects the crack detection information received by the crack detection information receiving unit 330 and the image received by the image information receiving unit 320 and collects the crack image information generated in the communication line, and finally cracking occurs. Judge.

When the crack detection information and the crack image information are different, the control unit 360 controls the driving module 200 to move to a corresponding position so that the IoT-based communication line monitoring device according to the present invention closely re-detects the corresponding part. , By controlling the camera 170 and the crack detection sensor, the corresponding part is re-photographed and re-detected.

The control unit 360 calculates the crack size, depth, etc. of the part where the actual crack has occurred through re-detection.

The control unit 360 calculates the size of the crack through image processing, and compares the time that the ultrasonic wave is reflected from the surface of the communication line where the crack has not occurred and the time that is reflected from the cracked part and returns to the depth of the crack. Calculate

The display unit 340 processes the crack detection information received by the crack detection information receiving unit 330 and the image received by the image information receiving unit 320 to display the crack image information generated in the communication line, and determine the final Display the crack result.

The button unit 350 is formed on the outer circumferential surface of the body 100 so that the inspector can set to drive the IoT-based communication line monitoring device according to the present invention.
