Abstract: The present disclosure discloses an optical measurement device and method for a plasma magnetic field with adjustable sensitivity. The method comprises the following steps: constructing an optical rotation measurement system based on a pulsed laser beam for measuring an optical rotation image and a shadow image; processing the optical rotation image and the shadow image, and obtaining a distribution of proportional coefficients based on alight intensity distribution; obtaining a distribution of rotation angles based on a mapping relationship between the proportional coefficients and the rotation angles; constructing an interference measurement system based on the pulsed laser beam, and measuring a phase shift of an interference image; calculating a distribution of electron areal densities based on the phase shift in the interference image; obtaining a two-dimensional distribution of an average magnetic field based on the rotation angles and the electron areal densities.

Abstract: A gateway Auto-Configuration Server (ACS) generates a service template according to service server information received from a service server, where the service template includes a first application identifier corresponding to an application service; a home gateway acquires the service template from the gateway ACS, and creates a virtual client for the application service corresponding to the first application identifier, and when an application service corresponding to a second application identifier acquired from a terminal belongs to the application service corresponding to the first application identifier, maps information corresponding to the second application identifier, to the virtual client corresponding to the first application identifier, and the virtual client implements message exchange between the service server corresponding to the first application identifier and the terminal.

Abstract: A method, a gateway, an auto-configuration server, and a system for managing devices in batches are provided. The method includes: creating a batch management group according to a batch management group creation rule and device information in a network; receiving a batch management command sent by an auto-configuration server for devices in the batch management group; determining a device that needs to be managed in the batch management group according to the batch management command; converting the batch management command into a command supported by the device that needs to be managed; and sending the command supported by the device that needs to be managed to the device that needs to be managed. The method implements batch management of devices in a network covered by a gateway.
