Abstract: A storage device, a data communication method, and a system, related to the field of optical communication technologies. A network adapter in the storage device implements OTN encapsulation of data, so that an OTN frame to which the data is mapped can be generated without transmission and encapsulation of the data through a plurality of devices. This reduces transmission latency of the data from a memory to an optical transceiver, and improves data communication efficiency. In addition, because the data does not need to be processed through an Ethernet switch, a protocol stack used by the storage device to encapsulate the data into the OTN frame does not need to use an Ethernet protocol. This simplifies an encapsulation procedure required for generating the OTN frame, reduces an amount of data included in the OTN frame, and helps further improve the data communication efficiency.

Abstract: The present disclosure provides a method for testing an internal force increment of an arch bridge suspender by inertial measurement, including the following steps: (1) selecting a suspender to be tested with internal force increment, and mounting an acceleration sensing device or a speed sensing device at a lower edge of the suspender to be tested; (2) setting an appropriate sampling frequency and collecting signals; (3) processing information data collected in step (2) by using Formulas; and (4) recording a result of the information data processing and obtaining the internal force increment of the suspender. The method can obtain the internal force increment of the suspender by collecting acceleration or speed signals of the lower edge of the suspender and performing calculation from the signals. This method has the advantages of simple and convenient testing, high replicability and low test cost.
