Abstract: A data concentration system for an inner detector of an oil-gas pipeline, and a timing control method, the system includes: a multi-channel data receiving module, a data concentration module and a data transmission module. The multi-channel data receiving module is electrically connected to a plurality of probes of an inner detector and is configured to receive detection data acquired by the plurality of probes. The data concentration module is electrically connected to the multi-channel data receiving module, and is configured to receive the detection data outputted by the multi-channel data receiving module and compress the detection data. The data transmission module is electrically connected to a data storage module of the inner detector and the data concentration module respectively, and the data transmission module is configured to receive compressed detection data.

Abstract: A dynamic magnetic field detection probe and an array control method. The dynamic magnetic field detection probe includes a dynamic magnetic field detection module, a master controller module, and a communication module. The master controller module is electrically connected to the dynamic magnetic field detection module. The communication module is connected to the master controller module by communication. The master controller module transmits acquired data to the communication module. The dynamic magnetic field detection probe is capable of detecting small-sized defects and has high precision.
