Large-batch weighing electronic scale providing open source data interface

Abstract

The invention relates to a large-batch weighing electronic scale providing an open source data interface, and relates to the technical field of electronic scales. The large-batch weighing electronic scale comprises a weighing module, a main control unit, a communication module, a display module and a data storage module. The weighing module is connected with the main control unit; the output end of the main control unit is connected with the display module and the data storage module to transmit the processed data to the display module and the data storage module; the display module establishes a man-machine interaction function interface with the main control unit through an SPI protocol; the communication module is connected with the data storage module and used for transmitting data to a client, and comprises an open-source USB data interface for converting the weighing data into a corresponding standard data format or a general file format and transmitting the weighing data to a PC terminal, a mobile phone terminal or a USB flash disk. The large-batch weighing electronic scale provides a plurality of weighing modes, the weighing data can be transmitted in an online mode and an offline mode, an open-source data interface is provided for a user, and the weighing data is stored and transmitted in a standardized data format and a universal file format.

Description

technical field [0001] The invention relates to the technical field of electronic scales, in particular to a mass weighing electronic scale providing an open source data interface. Background technique [0002] With the advent of the industry 4.0 era, industrial products are no longer satisfied with traditional production technology, but are more developed towards intelligent equipment, and use information technology to promote industrial reform and radiate new vitality. The electronic scales in the prior art can only complete the conventional weighing method of single weighing when weighing objects. Even if there is a function of batch weighing, it needs to be completed through repeated operations of buttons or display screens, or the single weighing The measurement results are transmitted to the host computer for processing to obtain batch weighing data. The whole weighing process is relatively cumbersome. For the weighing of large quantities of goods, the efficiency is gr...

Problems solved by technology

The electronic scales in the prior art can only complete the conventional weighing method of single weighing when weighing objects. Even if there is a function of batch weighing, it needs to be completed through repeated operations of buttons or display screens, or the single weighing The measurement results are transmitted to the host computer for processing to obtain batch weighing data. The whole weighing process is relatively cumbersome. For the weighing of large quantities of goods, the efficiency is greatly reduced; and the data transmission of existing electronic scales often only provides online transmission mode. The weighing data is transmitted in real time through USB or Bluetooth, and only simple weighing data is transmitted without format conversion of the data. Users cannot directly import and process data, which cannot meet the needs of laboratories, scientific research institutes, etc. for offline storage and storage. User's needs in the application of exporting weighing data
