Embodiment 1

[0035] See figure 1 , The present invention discloses a POS system. The POS system includes a smart host (such as a smart phone or tablet), a receipt printer, a keyboard or barcode scanner, and a Bluetooth connection device; the Bluetooth connection device is connected to the smart host, receipt printer, Keyboard or barcode scanner.

[0036] The Bluetooth connection device includes an MCU input and output module and a Bluetooth transmission module, and the Bluetooth transmission module is connected to the MCU input and output module. The MCU input and output module includes an MCU processor, two USB-A type interfaces, the MCU processor is respectively connected to each USB-A type interface; the two USB-A type interfaces are respectively connected to a receipt printer, a keyboard or a barcode scanner

[0037] See figure 2 After the Bluetooth connection is established, the smart host sends data through the Bluetooth serial port in the machine, and the sent data is received by the M...

Embodiment 2

[0040] A Bluetooth connection device, the Bluetooth connection device includes: an MCU input and output module, a Bluetooth transmission module; the Bluetooth transmission module is connected to a host; the MCU input and output module includes an MCU processor and at least two USB interfaces; the MCU processors are connected separately Each USB interface; each USB interface is connected to the corresponding external device.

[0041] In summary, the POS system and Bluetooth connection device proposed by the present invention can enable the smart host to realize the interconnection and intercommunication with keyboard devices such as receipt printers and barcode scanners on a Bluetooth connection. The invention also solves the problem that the input content of the input device such as the barcode scanner is incorrectly converted by the input method software on the smart host.

Abstract

The invention discloses a POS system and a Bluetooth connection device. The POS system includes a smart phone or tablet computer (intelligent host), a receipt printer, a keyboard or a barcode scanner, and a Bluetooth connection device; the Bluetooth connection device is connected to the smart host, the receipt printer, and Keyboard or barcode scanner; Bluetooth connection device includes MCU input and output module and Bluetooth transmission module; Bluetooth transmission module is connected to smart host and MCU input and output module respectively; MCU input and output module includes MCU processor and at least two USB interfaces; MCU processor Connect each USB interface respectively; each USB interface is connected to a receipt printer, keyboard or barcode scanner. The POS system and Bluetooth connection device proposed by the present invention can enable the intelligent host to realize interconnection and interoperability with keyboard devices such as receipt printers and barcode scanners on a Bluetooth connection. The invention also solves the problem that the input content of input devices such as barcode scanners is incorrectly converted by the input method software on the smart host during conventional connection.

Description

Technical field [0001] The invention belongs to the technical field of electronic communication, and relates to a POS system, in particular to a smart POS system connected via Bluetooth; at the same time, the invention also relates to a Bluetooth connection device. Background technique [0002] With the rapid popularization of smart phones and tablet computers (smart hosts), more and more smart hosts are used as commercial terminals for sales, inventory, membership management and even cash registers. However, due to the relatively limited type and number of external interfaces of ordinary mobile phones and tablets (usually only one headphone jack and one USB charging port), it is very inconvenient to access commonly used keyboards, barcode scanners, receipt printers and other commercial peripherals. [0003] The current common practice is to buy a Bluetooth scanner and a Bluetooth printer, and establish a Bluetooth connection with the smart host respectively. The problems with thi...
