Embodiment Construction

[0023] The invention principle, features and advantages of the present invention are described in detail as follows in conjunction with the accompanying drawings.

[0024] In general barcode recognition equipment, in addition to the main chip, flash memory (Flashmemory) is generally provided, and a code scanning function application module and a bootloader module (bootloader) are placed inside; for the needs of practical applications, the current barcode The boot loading module of the scanning device does not contain a device descriptor conforming to the standard protocol of the USB disk. Therefore, when the barcode scanning device is connected to the host computer (computer), it will not be recognized as a USB disk by the host computer. For the purpose of the present invention, the barcode scanning device of the present invention needs to be used as a USB flash drive, therefore, the USB device descriptor conforming to the standard protocol of the USB flash drive needs to be wr...

Abstract

The invention relates to a firmware updating method of a barcode recognition device. The device comprises a flash memory, which comprises a code scanning function application module and a starting and loading module, the starting and loading module contains a USB device descriptor satisfying a USB flash disk standard protocol, and the firmware updating method comprises the following steps: connecting the barcode recognition device with a host; detecting that a scanning trigger key is pressed by the starting and loading module to enter a USB flash disk mode; putting a to-be-updated firmware file in a USB flash disk file catalog by a user; detecting the file satisfies a specified file name by the starting and loading module; and updating the to-be-updated firmware file by the starting and loading module. According to the firmware updating method provided by the invention, the device descriptor satisfying the USB flash disk standard protocol is written in the device is advance, the device enters the USB flash disk mode through a specific flow design, so that the user can conveniently place the to-be-updated firmware file in a flash memory to automatically update the firmware, and thus the adaptability and the convenience of the device are improved.

Description

technical field [0001] The invention relates to the technical field of automatic identification, in particular to a method for updating firmware of a barcode identification device. Background technique [0002] With the rapid development of informatization in today's society, people need to process more and more data information, and it is obvious that manual data processing is far from meeting the needs of development. The data is formed into symbols that can be recognized by equipment through various encoding methods, and then the data collection is completed through equipment recognition, which solves the problems of slow manual data input, high error rate, high labor intensity, simple and repeatable work, etc. Information processing provides an effective means for fast and accurate data collection and input. Therefore, automatic identification technology based on symbol recognition, as a data collection technology, is rapidly being widely used in many industries and appl...
