The system comprises a weighing sensor, a data transmission module and an intelligent mobile terminal, wherein the data transmission module comprises a processor, a filter circuit, an analog-to-digital conversion module, a storage module and a communication module; the processor is respectively connected to the filter circuit, the analog-to-digital conversion module and the communication module; the weighing sensor is connected to the filter circuit; the communication module is connected to the intelligent mobile terminal; and thecommunication module is a Bluetooth module or a WiFi module. Compared with a traditional electronic scale device, the system has better usability, portability and expandability.

Description

technical field [0001] The invention relates to the technical field of electronic scales, in particular to a wireless weighing method and system thereof. Background technique [0002] The traditional electronic scale equipment consists of a weighing meter and a weighing sensor. The weighing meter is composed of LCD display or digital tube display, thin film operation panel, status indicator light, MCU, and AD chip module. The weighing meter head is connected to the weighing sensor through the signal line, and the user realizes various weighing operations and parameter settings through the thin film operation panel. Traditional electronic scale equipment is connected to printers, three-color warning lights, weighing display screens, PC ERP (Enterprise Resource Planning, enterprise resource planning) systems, blanking equipment, PLC, barcode scanners, NFC card readers, etc. A kind of external hardware device communication. It can also cooperate with the mobile APP to displa...

AI Technical Summary

Problems solved by technology

[0004] 1. The connection between the weighing meter and the weighing sensor is limited by the connection of the signal line, and the weighing meter is large in size, so it cannot be moved at will, and the mobility is poor

[0005] 2. Traditional electronic scale equipment needs to use communication to communicate with various external hardware devices such as printers, three-color warning lights, weighing display screens, PC ERP systems, blanking equipment, PLC systems, barcode scanners, and NFC card readers. Cable links, so the mobility is poor, the wiring is more complicated and takes up space, and the cost of production and deployment is higher

[0006] 3. Traditional electronic scale equipment is limited by the number of external device interfaces, and the number of external devices that can be connected at the same time is limited.

[0007] 4. Traditional scale equipment labels and bill formats cannot be edited or added on the weighing meter header at will. They need to be edited on a PC and downloaded to the internal memory of the electronic scale or downloaded to the internal memory of the printer to print the new format.

Therefore, the cost of changing the printing format of labels and bills of traditional electronic scale equipment is high and the efficiency is low

[0008] 5. The mobile phone APP matched with the traditional electronic scale equipment can only be used to display the weighing data function, and cannot realize all the functions of operating the electronic scale. The APP function is relatively single

[0009] 6. The buttons on the thin-film operation panel of traditional electronic scale equipment have poor hand feeling, the display effect of LCD display or digital tube display is poor, and the various function setting menus are difficult to understand

[0010] 7. Traditional electronic scale equipment has no operator identification function and cannot record user information

[0011] 8. Traditional electronic scale equipment cannot locate the user's location with GPS and base stations

[0012] 9. The number of weighing platforms that can be connected to one piece of traditional electronic scale equipment is small
