The signals collected by the mobile intelligent detection platform are automatically stored in a cloud database for automatic filing, and according to the set detection data weight, the geological conditions of the data base, the operating conditions (temperature, pressure and medium) of the PE pipe and the season and temperature of the data collection at that time are combined, and the collected data are automatically classified and sorted by the above points.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
