data storage device

Abstract

The invention discloses a data storage device. The data storage device of the present invention uses a non-standard three-wire serial communication circuit based on the I2C bus to respectively amplify and reshape the clock signal and the data signal and then transmit them to the storage circuit for storage. The data in the storage circuit passes through After reshaping, it is output to the host computer. Compared with the two-wire serial method adopted by the existing standard I2C bus communication circuit, that is, the serial method of one input signal line and one output signal line, the advantage is that it will not appear in long-distance transmission. Data loss greatly improves the data transmission distance and the use range of I2C bus communication, and the reliability and stability of data transmission are better. Moreover, although a non-standard three-wire serial communication circuit is used, its data communication protocol is consistent with the standard two-wire communication protocol, and can be directly applied to the I2C communication protocol, so that there is no need to design special transceiver circuits at both ends of the IC to achieve long-distance Data transmission greatly reduces the complexity and cost of the system.

Description

technical field [0001] The present invention relates to the technical field of aero-engine data storage modules, in particular to a data storage device. Background technique [0002] The data storage module is an important part of an aero-engine, usually using E 2 PROM (Electrically Erasable Programmable Read-Only Memory) realizes the storage of engine data, mainly storing engine serial number, working time, IGV (inlet guide vane) angle, ECS (electrical control system), working times and health management statistics and other parameters , providing an important data reference for engine maintenance and data analysis. The data storage module is directly installed on the engine, which is equivalent to the electronic resume of the engine. 2 C bus communication protocol is to realize data transmission between ICs. [0003] The natural environment and electromagnetic environment that avionics products must withstand are relatively harsh. Generally, they should work stably and ...
