Embodiment Construction

[0023] Such as figure 1 Shown, be the first embodiment of the present invention, the recording pen in this embodiment comprises: carry out the USB interface that carries out data interaction with computer through USB interface, the controller that is connected with USB interface, the microprocessor that is connected with controller (MPU) and storage module, and the data recovery module that is connected with MPU, connects the detection module of MPU, and this detection module is used for detecting whether boot operation, when there is boot operation, detection module reports to MPU. The MPU sends the received signal to the data recovery module, the data recovery module generates a data recovery command, and sends it to the controller of the recording pen through the MPU, and the controller restores and saves the data in the storage module according to the data recovery command. The storage module in this embodiment may be a flash memory (FLASH) chip, and the FLASH is divided i...

Abstract

The invention relates to an electronic recording device providing the power-fail data protection, which comprises an interface which exchanges data with an external device, a controller connected with the interface, a storage module connected with the controller, and a microprocessor connected with the controller, and further comprises a data recovery module connected with the microprocessor, and a detecting module which is connected with the microprocessor and is used for detecting data conditions. Since using the technical proposal, the data before the power-fail can be recovered and stored under the condition that an electronic recording device is power-failed, which guarantees the safety of data and satisfies the requirements of optimum data storage under the condition of power-fail.

Description

【Technical field】 [0001] The invention relates to an electronic recording device for realizing data storage, in particular to an electronic recording device for saving data when power is off. 【Background technique】 [0002] With the development of technology, most mobile electronic devices use flash memory (FLASH) as the storage medium, and increase the corresponding recording function, and communicate with the computer through the USB interface with the USB MASSSTORAGE protocol (recognized by the computer as USB MASS STORAGE DEVICE) connect. In particular, digital tape recorders and digital recording pens are more and more widely used. Recording with portable electronic devices has become a frequent function in people's daily work and life. [0003] In the process of using a digital recorder to record, if the battery suddenly loses power or other factors cause a sudden power failure, most of the existing digital recorders cannot save the data content that is being recorde...
