The management server 1 includes a control unit 11, a DATA readout processing unit 12, a memory unit 13 and a transceiver unit 14. The detection unit 2A includes a first detection unit 21, 2 detection unit 22, and is constituted by a signal transmission / reception unit 23.

The control unit 11 controls the operation of the detection unit 2A and transmits information to the user personal communication means 3 connected to the management server 1 and control inputted from the personal communication means 3 Command and so on.

In addition, the DATA reading unit 12 plays a role of reading DATA input from the detecting unit 2A through the transmitting / receiving unit 14. [

In more detail, the displacement value information inputted from the detection unit 2A is input, and the determination as to whether the displacement value information is close to the limit set by the user, the position information of the installed seat is analyzed, It will be done.

For example, information such as location information of input information, that is, recognition information of a bridge, and serial number of a teaching program, are input and a unique data value according to a bridge is generated.

The memory unit 13 stores the data input from the detection unit 2 and the information processed in the DATA reading unit 12.

This is for the user to connect to the management server 1 through the external network to confirm the information of each bridge, or to compare the displacement value of the desk.

The transmission / reception unit 14 is responsible for transmission / reception between the detection unit 2A and the user personal communication means 3, and is provided with an external computer network or wired / wireless communication means.

Here, the external computer network utilizes the Internet or a network, and the wired / wireless communication means can be any means capable of short-range communication, and is applicable in the field at the time of checking and repairing the teaching paper.

The detecting unit 2A interlocked with the management server 1 includes a first detecting unit 21 for measuring the displacement of the bridge and a second detecting unit 21 for measuring the displacement value by the first detecting unit 21. [ And a signal transmission / reception unit 23 for transmitting the information detected by the first detection unit 21 and the second detection unit 22 to the management server 1.

The first detection unit 21 as described above measures the horizontal displacement of the desk and measures the height between the bridge top plate and the bridge pier arranged on one side of the bridge pier and bridge pier.

For this, a photodiode 21a and a photodetector 21b corresponding to the photodiode 21a are formed.

More specifically, it is to judge whether or not the horizontal displacement of the horizontal axis, that is, the movement of the vertical axis.

Here, whether or not the displacement in the horizontal direction refers to the inclination of the diagonal.

To this end, the photodiode 21a and the photodetector 21b are disposed opposite to each other so as to be close to one side of the vertical wall surface of the desk, and the signal transmission / reception unit 23 To the management server 1, and reads the information through the DATA reading unit 12. [

And controls the operation of the second detection unit 22 of the corresponding school based on the information thus read out.

The second detection unit 22 is formed integrally with a laser oscillator (not shown) and a detector (not shown) for detecting the laser oscillated from the laser oscillator. The laser oscillated from the laser oscillator is reflected And the reflected laser is detected by a detector.

At this time, two or more second detection units 22 as described above are disposed at the lowermost end and the uppermost end of the diagonal, respectively, to detect the inclination value of the diagonal.

For this purpose, the laser light is arranged in a direction perpendicular to the wall surface of the desk so that the laser light can be radiated perpendicularly to the wall surface of the desk, and the tilt value of the desk is detected by sensing the distance between the second detecting unit 22 and the desk.

More specifically, the distance between one second detection unit 22 disposed at the lowermost end of the teaching frame is detected by a laser, and the distance between another second detection unit 22 disposed at the uppermost end and the teaching pad is detected Then, the two distance values are compared to determine the slope.

This is because the laser oscillated from the laser oscillator is reflected on the wall surface of the desk, and the distance is measured using the time detected by the detector. Such a distance sensing method is a known technique, and therefore, a detailed description thereof will be omitted.

The second detection unit 22 is arranged so that two or more detection units 22 are arranged on the same line in the vertical direction so as to maintain the same distance as the bridge, And is disposed on a separate mounting bar 23.

5 is a flow chart of a method for checking the schedule of the system of the present invention.

5, in step S10, information on whether or not a teaching displacement is inputted from the first detection unit 21 is input. In step S20, (S30) of instructing the operation of the second detection unit 22 of the corresponding school according to the data, analyzing the displacement value detected from the second detection unit 22 (S40) (Step S50) of comparing the stored displacement value with a threshold value (step S60), and storing the comparison result and notifying the user of the comparison result (step S70). So that the abnormality of the timetable is checked.

The step S10 of inputting information on whether or not a teaching displacement is received from the first sensing unit 21 refers to the horizontal movement of the teaching subject, that is, whether or not the teaching subject is tilted. That is, whether or not the teaching subject is tilted due to external factors, It is judged.

To this end, a photodiode 21a and a photodetector 21b are arranged in the vertical direction of the school, and the first detection unit 21, which is arranged as described above, It is transmitted to the management server 1.

More specifically, if the optical signal is not transmitted to the photodetector 21b from the photodiode 21a disposed close to the vertical plane of the desk, the optical signal is judged to be interrupted by the interference of the desk, It will be judged whether or not.

Step S20 of generating unique data for the teacher from the input information using the displacement input information of the teacher input as described above generates unique data such as position information of the teacher's desk, It refers to unique data such as identification information of the detected plan.

The generation of the unique data is for judging, analyzing and storing the input information.

It is also intended to control the operation of the CCTV surveillance camera which can be added.

Here, after step S20, a step S25 for searching for a surveillance CCTV camera for location information search and operation control of the surveillance surveillance CCTV camera may be further included.

The step S30 of commanding the operation of the second detection unit 22 of the corresponding tally according to the unique data generated in the step S20 corresponds to the step S30 of the second detection unit 22 according to the displacement of the tilt detected by the first detection unit 21 The detection unit 22 is operated.

This is for detecting the inclination value of the desk when the first detection unit 21 detects the horizontal movement of the desk, that is, whether or not the desk is inclined.

For this purpose, the detection value of each of the second detection units 22 provided for two or more, that is, the distance to the intersection, is measured to analyze the tilt value.

In this case, the first detection unit 21 further includes a process of detecting whether or not the first detection unit 21 is operated. If the first detection unit 21 does not operate for a predetermined period of time, After the displacement value is measured, it is judged whether or not the first detection unit 21 is damaged.

If the first detection unit 21 does not operate, the controller notifies the manager of the failure or not.

The non-operation time interval for detecting whether or not the first detection unit 21 is operated may be set by the user or may be compared with the average value of the operation time period and the operation time of the first detection unit 21 And it applies them.

For example, if the first detection unit 21 operates at intervals of 10 minutes in commute time, the non-operation time of the first detection unit 21 is set in the commute time zone by analyzing the accumulated data related thereto, will be.

The detection value inputted in the above step S30 is analyzed by the DATA reading unit 12 of the management server 1 to detect the displacement value detected from the second detection unit 22 for analyzing the displacement value which is the tilt value (Step S40).

In this case, the tilt value of the tilt is determined by using the difference between the distances between the second detection unit 22 and the side surface of the tilt sensor, which are disposed at the lowermost end and the uppermost end of the tilt sensor, , The slope value is determined.

The step S50 of storing the displacement value analyzed in the step S40 in the memory unit 14 is performed by storing the displacement value read by the DATA reading unit 12 in the memory unit 14 together with the unique data will be.

In step S60, the displacement value stored in the memory unit 14 is compared with the displacement value stored in the memory unit 14 by the user.

Here, the threshold value refers to a slope tolerance value of a teaching subject, and a tolerance range can also be selectively input.

In step S60, the comparison result comparing the displacement value and the threshold is stored and the step S70 of notifying the user is stored in the memory unit 14, and the user is notified of the abnormality.

Here, the method of notifying the presence or absence of the abnormality may be applied using a notification function, that is, an alarm method, but is not limited thereto.

In addition, after step S70, step S80 may be performed to generate information on the amount of displacement for each time period, season, and region by using cumulative data on displacement values per bridge using stored information.

This is to make it possible to judge the life span of the bridge by analyzing the safety check and cumulative data of the bridge.
