The construction concrete material management system may manage the test block for the quality test of the construction material and the results of the test block through the management server 100 . In this case, a communication tag may be embedded in the test block. The embedded communication tag is designed to perform a communication function even after the construction concrete is hardened, and can perform a predetermined communication function until its own communication function is destroyed. The communication tag corresponds to the test block and performs a function of providing information about the test block. Here, the communication tag may include all of communication through a local area network such as an RFID tag and an NFC tag, and in particular, may include a passive RFID tag and an active RFID tag that operate by receiving power from an external electromagnetic field. A communication tag typically has at least two components: an integrated circuit (IC) for storing and processing information, modulation and demodulation of radio frequency (RF) signals, and other specialized functions, such as an external reader (or interrogator). ) can be designed to include an antenna (ANT) for receiving and transmitting a signal from.

It is possible to manage the availability and integrity of construction concrete materials. The integrity of the construction concrete material may be determined through whether the information obtained by recognizing the invoice information of the transport device 200 and the communication tag matches the information obtained. In this case, the communication tag may be provided in correspondence with the transport device 200 or may be provided in correspondence with the construction concrete material. The communication tag includes a short-range communication transceiver, and refers to anything implemented to communicate through a communication network such as RFID, NFC, Bluetooth, ZEEBEE, and LoRA.

For construction concrete materials, it can be judged whether or not they meet the specified conditions after transportation is completed.

In the process of converting the construction concrete material into test blocks, the test blocks and corresponding communication tags are embedded in the test blocks to help identify the test blocks. In this case, the communication tag may be implemented to operate even after hardening of the construction concrete material. A process of registering a communication tag before embedding in the test block may be performed.

The identification information read from the communication tag may be transmitted to the management server 100 through the field management device 300 . The test blocks of the construction concrete material and the construction concrete material can be managed in correspondence with each other.

Test blocks for which the test is completed may be identified through the embedded communication tag 400 and managed through identification information of the communication tag 400 . The test result for the test block may be managed in association with the corresponding construction concrete material using the identification information.

The management server 100 may receive data from the field management device 300 and manage the test results in association with the communication tag 400 embedded in the test block. The management server 100 may search for the communication tag 201 of the transportation means corresponding to the test block by using information obtained from the communication tag 400 embedded in the generated task block. That is, apart from the communication tag embedded in the transported concrete construction material, test blocks generated from the concrete construction material may include individual communication tags. The management server 100 may check whether the communication tag 201 of the transportation means and the invoice information 211 of the transportation means match after being put into the construction site.

The management server 100 may acquire the location information of the test block through the field management device 300 sensing the communication tag 400 of the task block. The management server 100 may receive the location information of the test block periodically.

The management server 100 may receive the location information of the test block when the location information of the reader device provided in the test space and/or the location information of the test block sensed by the field management device 300 match. .

The captured image captured by the monitoring device 500 may be transmitted to and managed by the management server 100 . When the identification information of the communication tag of the test block is input, it may be implemented to provide a photographed image of the test process of the test block. The monitoring device 500 may analyze the captured image to extract whether the position of the test block is changed. It may be determined whether the position of the test block is changed in the captured image without the test block being located at a certain position.

The construction concrete material management system may manage the test result of the test block in association with the communication tag 201 of the transport device and the invoice information 211 of the transport device.

The transportation means for the construction concrete material is a means for moving the construction concrete material, and may be implemented by including a transportation device. The transportation device 200 may periodically transmit movement information between the departure location and the arrival location to the management server 100 .

The transport device of the construction concrete material is identified through the invoice information 201 and/or the communication tag 211, and when the movement to the construction site is completed, the transport means is identified by cross-checking the invoice information and the communication tag can do. The identification of the vehicle may mean that the construction concrete material transported by the vehicle is identified.

When the transportation means is identified, the management server 100 may receive information on the departure time and information on the arrival time to calculate the travel time of the transportation device 201 .

Transport time = arrival time - departure time

The management server 100 may determine whether the movement time of each construction material is within a preset time range through the movement time of the transportation means.

Travel time of construction material <= preset time range

For example, the movement time of concrete construction materials in the form of ready-mixed concrete should be within 90 minutes. Through the management server 100, it is possible to accurately calculate and manage the movement time of concrete in seconds. For each type of construction concrete material, a limit on the travel time may be set.

When the registered communication tag is detected adjacent to the monitoring device 500, the video recording for the test area starts. Whether the communication tag is registered may be received from the management server 100 or the field management device.

The sensing device 510 may sense the temperature, humidity, etc. of the test site and periodically transmit the sensed value to the management server 100 . In particular, an appropriate water temperature required in the underwater property drying process of the test block may be sensed and the sensed value may be periodically transmitted.
