The invention discloses a pipe cutting device for a self-positioning pipeline. The device comprises a rack, and further comprises multiple straightening devices, a cutting machine and a positioning device which are sequentially arranged on the top of the rack in the machining direction; the cutting machine comprises a cutting table, two clamping tables and a cutting disc; the cutting table is fixed to the rack, the two clamping tables are symmetrically mounted on the two ends of the cutting table, the cutting disc is arranged on the cutting table through a supporting frame, the positioning device comprises a support, a screw, a servo motor, a baffle and automatic clamping claws, the support is fixed to the rack, multiple air cylinders which are arranged in a hanging manner are arranged onthe support, the automatic clamping claws are arranged on piston rods of the air cylinders, and a material accumulating groove is formed in the position, below the support, of the rack. The cutting machine and the positioning device are arranged, the long pipeline can be precisely positioned and cut, machining efficiency is improved, the process of cutting the pipeline again on the later is removed, and raw material waste is reduced.

In the implementation method, device and device for calibration of test equipment provided by this application, since the equipment information (including equipment location information) of each test equipment is stored in the blockchain network, the network nodes in the blockchain network can Equipment information and calibration conditions of the equipment, monitor the test equipment within its own node range, screen out the target calibration test equipment that meets the calibration conditions in a timely, accurate and automatic manner, and then generate the corresponding calibration notification information and send it to the preset terminal. To notify the preset calibrator to perform the calibration test on the target calibration test equipment in time, it does not require the calibrator to calibrate regularly, which improves the flexibility of calibration; in addition, the application will also synchronize the obtained calibration data to the blockchain network, which is convenient for subsequent arbitrary calibration. Users can access any network node of the blockchain network at any time to understand the calibration process and results of any test equipment, which realizes the transparency of the calibration process and ensures the fairness of the test equipment calibration.

The invention discloses a system, method and relevant device for screening users with defaulting risks, used for solving the problem that online charging is carried out on the screened users because the users with defaulting risks can not be screened in time in the prior art. The system comprises a rule server and a detection server; the rule server is used for obtaining a phone bill of each defaulting user within the preset time slot of a defaulting service according to the identity of the defaulting user and the identification of a corresponding defaulting service and determining a judgmentrule according to the obtained phone bill, wherein the judgment rule includes a parameter value range of a preset parameter relevant with the defaulting service; the detection device is used for obtaining the judgment rule from the rule server, determining the parameter value of the preset parameter of each user according to a real-time phone bill provided by a charging server, and determining the user as the screened user with a defaulting risk when the parameter value of the preset parameter of the determined user is within the parameter value range of the preset parameter included in the judgment rule.
