Abstract

The invention provides a method for converting serial data of an electronic scale into computer universal serial bus (USB) data, which comprises the following steps that: a computer sets a serial communication protocol of various electronic scales and a parameter for converting the elements and serial data of the electronic scale into a USB data format, and stores the protocol and the parameter in a flash chip; and a serial interface receives the serial data of the electronic scale, performs level conversion on the serial data through a serial chip, and sends the serial data subjected to level conversion to a singlechip, and the singlechip converts the serial data subjected to level conversion into a character string according to the parameter prestored in the flash chip, and sends the character string to the computer through a USB interface. The invention also provides a device for converting the serial data of the electronic scale into the computer USB data. By the method and the device, the difficulty of data transmission between a serial port of the electronic scale and a USB port is reduced, and the serial data of the electronic scale is converted, can be directly sent to software such as notepad, excel, word and the like of the computer and is stored.

Description

【Technical field】 [0001] The invention relates to the field of electronic weighing instruments, in particular to a method and a device for converting serial port data of an electronic scale into computer USB data. 【Background technique】 [0002] The external output interfaces of existing electronic scales are basically serial ports, that is, RS232 or RS485, and the development trend of computers is to support USB settings very well, and cancel the support for serial ports; new computers basically do not have RS232 ports. And Microsoft's new systems have canceled support for serial devices. The electronic scale still uses RS232 / RS485 communication, which makes it very troublesome to connect the electronic scale to the computer. If you use the current serial USB device on the market, the computer device needs to be installed with a driver, and you also need to know the serial USB device. Which COM port is simulated, and the USB interface is virtualized as a serial port. Howev...
