When the field manager executes the application of the portable measurement terminal 40, data transmission / reception is performed between the portable measurement terminal 40 and the measurement management server 30 thereafter.

Referring to FIG. 4, after the portable measurement terminal 40 logs into the measurement management server 30 (S100), it is determined whether manual upload is selected from the field manager (S110).

When manual upload is selected, a data input screen is displayed and data such as sensor measurement values are received from a field manager (S120).

FIG. 6 shows a screen for inputting sensor measurement values after selection of manual upload.

6, reference numeral 201 denotes an input field for inputting a sensor measurement value, reference numeral 203 denotes a button for upload selection, reference numeral 205 denotes a button for upload deletion, 207 denotes an upload list Respectively.

Next, the portable measurement terminal 40 judges whether there is an uploading request from the field manager (S130). The upload request is detected by touching the upload button 203.

If there is an upload request, the portable measurement terminal 40 generates an upload request signal and transmits the upload request signal to the measurement management server 30, and receives the calculation formula from the measurement management server 30. The calculation formula is a mathematical formula for calculating the calculation value by substituting the sensor measurement value. The calculation result calculated through the calculation formula is used to monitor and predict the behavior of the civil engineering structure.

The portable measurement terminal 40 obtains the calculation result using the received calculation formula, and determines whether the calculation result exceeds the management reference (S140). If the calculation result does not exceed the management criterion, the calculation result is simply displayed (S150). If the calculation criterion is exceeded, the calculation result is displayed together with the alarm (S152).

Here, there is a circle mark in each item, and a circle mark corresponding to the Y change amount is displayed in a different color. This indicates that the Y change amount exceeds the management standard.

The field manager can recognize that the Y variation is above the control criterion and can choose to upload or cancel the calculation results.

The portable measurement terminal 40 determines whether uploading or cancellation is selected from the field manager (S160). If it is confirmed that the upload is selected, the portable measurement terminal 40 transmits the sensor measurement value and the calculation result to the measurement management server 30 (S170) If it is confirmed that the selected content is selected, the uploading is canceled (S180).

In FIG. 4, the sensor measurement value and calculation result are transmitted to the measurement management server 30 immediately upon upload selection in the calculation result screen when the management reference is exceeded. However, as another embodiment, A pop-up window 213 may be displayed (refer to the screen (b) of FIG. 7).

In the second pop-up window 213, a message for finally confirming whether to upload the calculation result together with the alarm is displayed. When the field manager selects uploading, the sensor measurement value and calculation result are transmitted to the measurement management server (30).

When the uploading of the sensor measurement values and calculation results is completed, a new upload item is added to the upload list 207. It can be confirmed that the calculation result is added when the box portion of the dotted line in the upload list 207 of FIG. 8 is viewed.

8, only items such as date and time, X change amount, Y change amount, and comment item are displayed in the upload list 207. However, this is because the other items are not displayed due to the limitation of the screen size, You can check the result, X displacement and Y displacement, and you can check the sensor measurement value, measurement angle and measurement length.

In this way, the uploaded data can be deleted or modified as well as the function of registering the sensor measurement values and calculation results in the measurement management server 30 through manual uploading.

9 is a screen for deleting the uploaded data.

5, the portable measurement terminal 40 receives an ID and a password PW from a field manager and transmits the ID and the password PW to the measurement management server 30 (S10). The measurement management server 30 confirms the received ID and password and authenticates the login of the portable measurement terminal 40 (S12).

A session is created between the portable measurement terminal 40 and the measurement management server 30 at step S14 and data is transmitted and received between the portable measurement terminal 40 and the measurement management server 30 through the session. The measurement management server 30 allocates session information to the portable measurement terminal 40 at the time of creating the session.

After receiving the sensor measurement value from the field manager (S16), the portable measurement terminal 40 transmits a first upload request signal to the measurement management server 30 (S18) if there is a manual upload selection by the field manager. When the portable measurement terminal 40 transmits the first upload request signal, the portable measurement terminal 40 transmits the session information allocated thereto to the measurement management server 30 together.

When the measurement management server 30 receives the first upload request signal from the portable measurement terminal 40, the measurement management server 30 verifies the received session information (S20). When the session information is verified, the measurement management server 30 transmits a corresponding calculation formula to the portable measurement terminal 40 (S22), and the portable measurement terminal 40 substitutes the sensor measurement value previously input into the received calculation formula (S24).

The calculation formula transmitted from the measurement management server 30 to the portable measurement terminal 40 is a formula used for monitoring and predicting the behavior of the civil structure. It is set according to the civil engineering structure or the situation of the site. It can be changed according to the change.

The computed calculation value is displayed on the screen. If there is an upload selection of the field manager, the portable measurement terminal 40 transmits a second upload request signal to the management server 30 (S26).

The sensor measurement value and the calculation result are transmitted to the measurement management server 30 together with the session information upon transmission of the second upload request signal. When the measurement management server 30 receives the second upload request signal, it verifies the received session information (S28). When the session information is verified, the measurement management server 30 performs data registration on the sensor measurement value and the calculation result (S30).

When registering the data, the measurement management server 30 stores the alarm information together with the database in the case of registering the calculation result exceeding the management reference value.

When data registration is completed, the measurement management server 30 provides an upload screen to the portable measurement terminal 40 (S32). The field manager can check the uploaded items added from the upload list on the manual upload input screen.

In the embodiment of the present invention, the field manager directly inputs the sensor measurement value to the portable measurement terminal. However, the local communication unit may be operated on the manual upload input screen to receive the sensor measurement value from the sensor wirelessly.
