The present disclosure relates to security control methods and systems. The security control system may include at least one storage device storing a set of instructions; and one or more processors in communication with the at least one storage device, wherein when executing the set of instructions, the one or more processors are configured to direct the system to: obtain first data from a first device; obtain second data from a second device; associate and process the first data and/or the second data; and send the processed first data and second data to a server and/or a user terminal. The present disclosure can achieve linkage control of a plurality of access controls to meet the needs of users on indoor security.

Security control method and system

A data processing method includes: in the case where an operation state of an audio/video device in a target driving device is an out of operation state, generating an out of operation state notification message of the audio/video device; and sending the out of operation state notification message to a push client for stopping a data push between the push client and a push server using the out of operation state notification message.

Method and apparatus for processing data of a target driving device, electronic device and medium

The present invention provides a three-dimensional nuclear magnetic resonance logging instrument probe, a logging instrument and an antenna excitation method, where the probe includes: a probe framework, a magnet and an antenna; four magnets are uniformly distributed along a circumference of the probe framework, the magnets are magnetized in a radial direction of the probe framework, two magnets placed opposite to each other are magnetized from outside to inside, and the other two magnets placed opposite to each other are magnetized from inside to outside; in the probe framework, each of the magnets is provided with independently fed antennas; antennas corresponding to each of the magnets comprise a left antenna provided on one side of the corresponding magnet and a right antenna provided on the other side of the corresponding magnet; the left antenna and the right antenna corresponding to each magnet are electrically connected.

Three-dimensional nuclear magnetic resonance logging instrument probe, logging instrument and antenna excitation method

The present invention provides a multi-azimuth nuclear magnetic resonance logging instrument and an antenna excitation method, the nuclear magnetic resonance logging instrument includes: a probe framework and a shielding layer arranged in the probe framework; a plurality of main magnets are provided above and below the shielding layer, respectively; central axes of the main magnets are parallel with each other, and distances between the central axes of each of the main magnets and a central axis of the probe framework are the same; a distance between central axes of any two main magnets is not smaller than a first preset value; and an antenna is provided at outer side of each main magnet, and a plurality of the antennas are fed independently. In the present invention, circumferential recognizing capability of the nuclear magnetic resonance logging instrument can be improved and three-dimensional (radial, axial and circumferential) stratum detection can be achieved.

Multi-azimuth nuclear magnetic resonance logging instrument and antenna excitation method
