Abstract

This invention discloses one electron weight device to realize wireless data transmission method, which comprises the following steps: using one movable communication module based on movable network and establishing TCP layer socket on the servo terminal and connecting the electron weight device and movable communication module set; the device processing the daily work and storing the relative data; establishing TCP layer socket linkage at pre-set terminal through series communication interface control movable communication module in certain time; electron weight device sends or download data through electron weight device socket linkage and remote servo; after transmission, electron weight device controls movable communication function module and remote servo linkage to close communication.

Description

technical field [0001] The invention relates to a method for expanding mobile communication functions of an electronic weighing instrument, in particular to a method for realizing remote wireless data transmission of an electronic weighing instrument. Background technique [0002] The electronic weighing instrument can carry out accurate weight measurement, and at the same time, it can combine data calculation and data transmission functions, and can expand a variety of peripheral devices. With the advent of the modern information society, electronic weighing instruments have been widely used by manufacturers and merchants. However, at present, electronic weighing instruments and servers used for information processing generally use serial ports or Ethernet wired connections to upload and download data. For distributed applications, such as sales information management of chain stores, this traditional wired transmission method is no longer applicable. Contents of the inv...
