Embodiment Construction
[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0023] figure 1 It is a schematic flow chart of the firmware upgrade method of the LXI instrument of the present invention, as shown in the figure, the firmware upgrade method of the LXI instrument of the present invention specifically includes the following steps:
[0024] 1. Upload the new firmware at the remote end through the Web page of the LXI instrument, and send it to the LXI instrument. The remote end of the present invention refers to another place different from the location of the LXI instrument, that is, the present invention provides a method for remotely upgrading the LXI firmware.
[0025] Firstly, the control of file upload is developed in the Web page of the LXI instrument. In this embodiment, the FILE (file) control is used, and then the uploaded new firmware is sent to the LXI instrument end using the POST method....

The invention discloses a method for updating firmware of an LXI instrument, which comprises: a step A of uploading new firmware on a remote terminal through a web page of the LXI instrument and sending the firmware to the LXI instrument; a step B of receiving the new firmware at the LXI instrument; a step C of covering the original start file by using the new firmware; and a step D of covering the current start file of the LXI instrument by using delivery configuration firmware if the LXI instrument cannot work normally due to abnormal conditions in an updating process. When the method in the invention is adopted, the on-spot maintenance cost of the LXI instrument can be reduced considerably and the maintenance time of the instrument is shortened. The invention also correspondingly provides a device for updating the firmware of the LXI instrument, which comprises a firmware uploading module, a firmware receiving module, a firmware replacing module and an abnormal condition processing module.
Description
technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method and device for upgrading firmware (firmware) of an LXI (LAN eXtension for Instrument, extension of local area network in the field of instruments) instrument. Background technique [0002] The firmware of traditional instruments is generally directly solidified in non-volatile storage devices such as EEPROM (Electric Erasable Programmable Read Only Memory) or FLASH (flash memory) in the instrument. To upgrade the tools, the upgrade cost is high and the efficiency is low. [0003] The so-called LXI is a new instrument platform based on industrial standards such as Ethernet technology and composed of small and medium-sized bus modules. LXI instrument is an intelligent instrument based on LAN (Local Area Network, local area network) interface. Generally, a controller is integrated in the instrument, which has a LAN interface, receives remote control comma...
