The invention discloses a batch off-line downloader based on a ymodem protocol and an upgrading method. The batch off-line downloader comprises a key module, a central processing unit, a liquid crystal display, an LED indication module, a USB interface, a memory and a plurality of upgrading channels. The output end of the key module and the output end of the USB interface are connected with the central processing unit, the output end of the central processing unit is connected with the liquid crystal display and the LED indication module, and the central processing unit is further connected with the memorizer and each upgrading channel. Each upgrading channel is connected with an external HLPC communication module to be upgraded. According to the method, the USB interface is connected withthe external computer equipment, programs needing to be updated are copied from the computer equipment and then stored in the memory, the programs can be transmitted in an off-line mode through a ymodem protocol in the upgrading process, simultaneous upgrading of multiple modules is supported, and the upgrading result and version information are displayed. Compared with a traditional online upgrading mode, the method has the advantages that complex operations such as application programming, plug-and-play upgrading of the module, shell disassembly and jumper wire are not needed, equipment required by upgrading is simplified, the upgrading time is saved, and the upgrading efficiency is improved.
Description
technical field [0001] The invention relates to the upgrade of the HPLC communication module, in particular to a batch off-line downloader and an upgrade method based on the ymodem protocol. Background technique [0002] For industrial products (such as HPLC communication modules) whose programs are stored in SPI FLASH, the usual practice is to first burn the program into the FLASH through the SPIFLASH programmer, and then perform placement. After the finished product is finished, if the program needs to be upgraded, it needs to be connected to the computer through a serial port, and the computer upgrades the product through a specific application layer protocol or Ymodem protocol. [0003] However, the upgrade through computer connection can only be upgraded individually, and at the same time, the host computer software is required to upgrade, which is not conducive to batch upgrade of production, low efficiency, long upgrade time, and high error rate. Contents of the inv...
