Abstract: An apparatus and method for testing sensitivity consistency of an acoustic emission sensor are provided. The apparatus uses a cylindrical polymethyl methacrylate (PMMA) rod as a test bench. A clamping seat, a clamping block, and a mounting cylinder are mounted on one end of the test bench in cooperation. Under an action of a pressure spring, an end face of a tested sensor keeps pressure-stable coupling contact with an end face of the test bench. A bracket is mounted on another end face of the test bench, and keeps, together with a fixing seat and the clamping seat, the test bench horizontally placed on a desktop. By adjusting a width and an amplitude of a pulse excitation signal of a signal generator, and according to sensitivity distribution and aggregation between tested sensors, a consistency calculation method is used to screen out tested sensors with first, second, and third sensitivity consistency.

Abstract: A method for reporting and updating device description framework information. The device description framework information reporting method implements that the terminal device reports the updated device description framework information to DMS, which includes: updating the local device description framework information based on the changed structure of the device management tree; informing the updated device description framework information to DMS. The device description framework information updating method improves the validity of DMS's management over the terminal device. The updating method includes: receiving an updating inform about the device description framework information from a terminal device; acquiring the update of the device description framework information based on the updating inform; and updating the device description framework information of the terminal device stored locally based on the acquired device description framework information.
