Description

Technical Field

[0001] This utility model relates to the field of barcode scanner technology, and in particular to a Bluetooth terminal suitable for barcode scanner communication and charging. Background Technology

[0002] Currently, with the continuous improvement of informatization and automation, barcode technology is also constantly developing and being applied, and barcode scanners are widely used in various industries. However, the use of barcode scanners in the current technology still has many drawbacks, such as: some computers do not have Bluetooth devices, so barcode scanners cannot be directly connected to computers via Bluetooth; there are compatibility issues between different Bluetooth devices and barcode scanners, resulting in poor connection and transmission stability; when multiple barcode scanners are piled up together, it is impossible to determine which barcode scanner is connected to the Bluetooth device; and Bluetooth devices cannot charge barcode scanner batteries. Therefore, there is an urgent need to develop a Bluetooth terminal suitable for barcode scanner communication and charging to solve the above-mentioned technical problems.

[0003] In view of the above, this utility model is hereby proposed. Utility Model Content

[0004] The purpose of this invention is to provide a Bluetooth terminal suitable for barcode scanner communication and charging, effectively avoiding compatibility issues between Bluetooth devices and barcode scanners. It not only ensures stable connection and transmission but also secures the barcode scanner, charges its battery, and enables quick pairing via barcode scanning. This allows for convenient connection between the barcode scanner and the base. A search button allows users to locate the barcode scanner connected to the base. Output can be in HID or serial mode to meet diverse customer needs, demonstrating broad application prospects and promoting widespread adoption.

[0005] To achieve the above objectives, this utility model provides a Bluetooth terminal suitable for barcode scanner communication and charging, including a base and a cable. The base has a handle support for fixing the barcode scanner, contacting the bottom of the scanner handle to provide charging and communication contacts, and a quick pairing barcode for establishing a Bluetooth connection between the scanner and the base. The back of the base has an RS232 interface. One end of the cable is a USB interface, and the other end is an RJ45 interface. The USB interface connects to a PC, and the RJ45 interface connects to the RS232 interface on the base. The front of the base has indicator lights and buttons. The indicator lights include a mode switching success indicator, a scanner charging indicator, and a Bluetooth connection status indicator. The indicator lights and buttons include a mode switch button and a search button. The base houses an MCU. The RS232 interface connects to the MCU and Bluetooth module via contacts and 5V-5V and 5V-3.3V DC-DC converter chips, independently powering the MCU and Bluetooth module. The MCU's communication interface connects to the contacts for serial communication and to the Bluetooth module for Bluetooth communication. The MCU's output I / O ports connect to the mode switch success indicator, the scanner charging indicator, the Bluetooth connection status indicator, the mode switch button, and the search button, respectively. All indicator lights and buttons are controlled by the MCU's output I / O ports. The contacts connect to the RS232 interface, enabling the Bluetooth terminal to power the scanner and communicate with it.

[0006] Preferably, the mode switching success indicator light is powered by 5V and is controlled to light up by the MCU's output IO port OUTPUT1. When the HID mode is successfully set, the MCU obtains input information through communication, and at the same time, the MCU's output IO port OUTPUT1 outputs a low level, causing the HID mode indicator light to light up. At this time, the terminal device connected to the communication via the RS232 interface can input information at its cursor position.

[0007] Preferably, the barcode scanner charging indicator light is powered by 5V, and its illumination is controlled by the MCU's output I / O port OUTPUT2. When the serial port mode is successfully set, the MCU receives information indicating that the serial port communication is normal, and at the same time, the MCU's output I / O port OUTPUT2 outputs a low level, causing the serial port mode indicator light to illuminate. At this time, the connection and terminal devices need to communicate through serial port software.

[0008] Preferably, the Bluetooth connection status indicator is powered by 5V and is controlled by the MCU's output IO port OUTPUT3. When the Bluetooth module successfully connects to an external terminal device, the MCU obtains the connection success information through communication between the Bluetooth module and the MCU, and simultaneously drives the MCU's output IO port OUTPUT3 to output a low level, keeping it constantly lit. When the external Bluetooth device disconnects, the output IO interface is driven to output a pulse level, causing the Bluetooth connection status indicator to flash.

[0009] Preferably, the mode switching key enables the switching between HID mode and serial port mode of the terminal device.

[0010] Preferably, when the scanner is mixed, the search button locates the scanner that is currently successfully connected to the Bluetooth terminal. When the search button is pressed, the MCU's input IO port INPUT2 detects a high-level signal and simultaneously determines whether the Bluetooth terminal is successfully connected to the scanner. If the connection is successful and the high-level signal is maintained for more than 2 seconds, the scanner emits a prompt sound to indicate the scanner's position.

[0011] Preferably, the RS232 interface is powered by 5V.

[0014] 2. The RS232 interface (implemented via RJ45) of this utility model is the power supply interface for the Bluetooth terminal and can also power the scanner via contacts. In addition, the RS232 interface is also a communication interface, enabling communication between the Bluetooth terminal and client devices such as computers. Simultaneously, the RS232 interface and the Bluetooth terminal can also communicate with the scanner via contacts.

The handle support 5 supports and fixes the handle of the barcode scanner 7, keeping it upright and secure. The back of the base 1 has an RS232 interface 6. One end of the cable 2 is a USB interface 3, and the other end is an RJ45 interface 4. The USB interface 3 connects to a PC, and the RJ45 interface 4 connects to the RS232 interface 6 of the base 1. The front of the base 1 has indicator lights and buttons. The indicator lights include a mode switching success indicator light 10, a scanner charging indicator light 11, and a Bluetooth connection status indicator light 12. The buttons include a mode switching button 13 and a scanner finder button 14. The base 1 contains an MCU. The RS232 interface 6 connects to contacts 9, 5V-5V, and 5V. A -3.3V DC-DC converter chip is connected to the MCU and Bluetooth module, independently powering both. The MCU's communication interface connects to contact 9 for serial communication and to the Bluetooth module for Bluetooth communication. The MCU's output I / O ports are connected to the mode switching success indicator 10, the scanner charging indicator 11, the Bluetooth connection status indicator 12, the mode switching button 13, and the search button 14, respectively. All indicator lights and buttons are controlled by the MCU's output I / O ports. Contact 9 connects to RS232 interface 6, enabling the Bluetooth terminal to power the scanner and communicate with it. The RS232 interface 6 is powered by 5V.

[0025] The mode switching success indicator light 10 is powered by 5V and is controlled by the MCU's output IO port OUTPUT1. When the HID mode is successfully set, the MCU obtains input information through communication, and at the same time, the MCU's output IO port OUTPUT1 outputs a low level, causing the HID mode indicator light to light up. At this time, the terminal device connected to the communication via RS232 interface 6 can input information at its cursor.

[0026] The barcode scanner charging indicator light 11 is powered by 5V and is controlled to light up by the MCU's output IO port OUTPUT2. When the serial port mode is successfully set, the MCU receives information that the serial port communication is normal through communication. At the same time, the MCU's output IO port OUTPUT2 outputs a low level, which makes the serial port mode indicator light up. At this time, the connection and terminal device need to communicate through serial port software.

[0027] The Bluetooth connection status indicator 12 is powered by 5V and is controlled by the MCU's output IO port OUTPUT3. When the Bluetooth module successfully connects to an external terminal device, the MCU obtains the connection success information through communication between the Bluetooth module and the MCU, and at the same time drives the MCU's output IO port OUTPUT3 to output a low level, making it constantly lit. When the external Bluetooth device is disconnected, the output IO interface is driven to output a pulse level, causing the Bluetooth connection status indicator 12 to flash.

[0028] The mode switch key 13 enables the switching between HID mode and serial port mode of the terminal device.

[0029] The seek button 14 enables the scanner 7 to be successfully connected to the Bluetooth terminal when the scanner 7 is mixed. When the seek button 14 is pressed, the MCU's input IO port INPUT2 detects a high-level signal and determines whether the Bluetooth terminal is successfully connected to the scanner. If the connection is successful and the high-level signal is maintained for more than 2 seconds, the scanner will emit a prompt sound to indicate the scanner's position.

[0030] The RS232 interface 6 (implemented via RJ45) of this invention serves as the power supply interface for the Bluetooth terminal and can also power the scanner via contact 9. Additionally, RS232 interface 6 is also a communication interface, enabling communication between the Bluetooth terminal and client devices such as computers. Simultaneously, the RS232 interface and the Bluetooth terminal can also communicate with the scanner via contact 9. To prevent interference from external power sources, this invention incorporates an independent 5V-5V DC-DC conversion circuit, with the converted 5V powering the internal terminal. Since the main operating modules inside the terminal, such as the Bluetooth module and MCU, are powered by 3.3V, a 5V-to-3.3V DC-DC conversion circuit is also included, with the converted 3.3V powering the MCU, Bluetooth module, indicator lights, buttons, etc.

[0031] The RS232 interface 6 of this utility model can communicate with the MCU via serial communication, i.e., asynchronous communication via USART, to achieve wired interaction between the Bluetooth terminal and external devices; the Bluetooth module and the MCU can communicate with each other using UART communication, thereby realizing interconnection between the Bluetooth terminal and external Bluetooth devices.

[0032] This invention effectively avoids compatibility issues between Bluetooth devices and the scanner 7. It not only ensures stable connection and transmission but also secures the scanner 7 and charges its battery. By scanning the pairing barcode 8 with the scanner 7, a quick connection between the scanner 7 and the base 1 can be achieved, making it convenient to use.
