That is, the communication unit 340 allows the main server 300 to receive the measured values measured by the measurement unit 100 in each process directly or through the wireless transmission/reception unit 200, and to the main server 300 The role of providing the user terminal 400 through wireless communication of the received measurements and data requested by the user terminal 400 and receiving a process command input through the user terminal 400 by an administrator or operator Will do.

Next, the data analysis unit 350 serves to analyze the measured values measured by the measurement unit 100 and the data stored in the memory unit 310, and the contents analyzed by the data analysis unit 350 are Applied to current or future concrete product production processes.

In more detail, the data analysis unit 350 includes first to third analysis units 352, 354, and 356. In the first analysis unit 352, a measurement value measured in an aggregate process and an aggregate remixing process, that is, The data stored in the first and second databases 311 and 312 are analyzed to determine the contents of work to be performed in the aggregate process and the aggregate material mixing process.

That is, the board 500 is a product that is essentially used for the continuous mass production of concrete products, and is primarily located on the mold bottom of the concrete molding machine 30 to make concrete products such as bricks. When the concrete mortar is filled in the mold with holes, it plays the role of the lower mold to transmit the vibration of the molding machine 30 to the concrete product, and secondarily, the concrete product that has come out of the mold is transferred to the curing room (40). ) And performs the role of a pallet used when transporting products after curing.

When the shape of the board 500 is deformed, vibration transmission in the molding process is not performed evenly, making it difficult to produce high-quality concrete products, and when corrosion or scratches occur on the surface of the board 500, curing After the concrete product is separated from the board 500, there is a high probability of occurrence of defects, such as the side attached to the board 500 being torn off. Therefore, checking the shape and appearance of the board 500 is to ensure the production of high-quality concrete products. This is a process that must be essentially followed for this, and accordingly, in the present invention, it is configured to check whether the board 500 is abnormal through the second analysis unit 354.

Next, the density of the concrete product can be obtained by calculating using the volume and weight of the product. Since the volume and weight of the product are measured as described above, a detailed description thereof will be omitted.

In addition, the density of the concrete product may be estimated by comparing the total volume of the product and the volume of voids.Since the volume of voids formed in the concrete product is also related to the weight of the product, it is calculated using the volume and weight of the product. The correlation between the density and the ratio of the total volume of the product and the void volume calculated through the analysis of the measurement result using a laser is obtained, and through this, the density of the product is estimated only by the ratio of the total volume of the concrete product and the void volume. You can do it.

The estimation of the density of the concrete product as described above is similarly performed by the third analysis unit 356. When data that estimates the strength and density of the concrete product are accumulated using the ratio of the total volume of the concrete product and the void volume, the concrete product Since the correlation between the ratio of the total volume and the void volume and the strength and density of the product can be obtained more accurately, the third analysis unit 356 uses only the ratio of the total volume of the concrete product to the void volume. It is possible to estimate the strength and density of

Next, the components of the concrete product may be analyzed through a spectral analysis of light, and the third analysis unit 356 is provided with a component analysis module such as a spectrometer (spectrometer, not shown), and second and third photographing means Through the spectroscopic analysis of the laser irradiated from the laser irradiation unit provided in (124,126) to the product after molding and curing, the components contained in the concrete product, especially the oil, salt, pH, bacteria such as bacteria, etc., will adversely affect the quality of the concrete product. It is configured to detect possible components.
