Description

Technical Field

[0001] This utility model relates to the field of reader / writer technology, and in particular to a novel VEGA reader / writer. Background Technology

[0002] Currently, the Vega reader from ThingMagic is a standalone UHF RFID reader that communicates via a standard serial interface. It is built on ThingMagic modules, supports IP67 protection, and has three TNC RF output interfaces with a maximum of 30dBm and one standard RS232 serial port with a DB9 interface.

[0003] However, this reader / writer has many shortcomings:

[0004] It relies on imports, has limited functionality, and has high usage and development costs;

[0005] In scenarios such as the intelligent transformation of warehouse forklifts, it is not only necessary to equip the reader with a corresponding antenna, but also to lay power lines and serial communication lines on the forklift arm. Furthermore, the forklift power supply needs to be stepped down to the power supply voltage of the reader, which makes the setup cumbersome and the debugging troublesome, further increasing the cost.

[0006] Therefore, we propose a novel VEGA reader / writer to address the aforementioned technical problems. Summary of the Invention

[0007] The purpose of this invention is to provide a novel VEGA reader / writer to solve the problems mentioned in the background section.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: including a shell, a communication interface module, a power supply module, and an RF module;

[0009] The outer shell is a flat, thickened structure made of one-piece CNC milled aluminum alloy.

[0010] The communication interface module includes a DB9 female RS232 serial port, an M12-5pin aviation male interface, and a BT RF port;

[0011] The power module supports a wide power supply range of 9-36V, and the total power consumption of the whole machine is ≤10W.

[0012] The RF module is a UHF RFID module.

[0013] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, its main features are:

[0014] This device uses a flat, thickened, one-piece aluminum alloy CNC-milled shell, which not only takes up little space and is resistant to impact and friction with a protection level of no less than IP67, but also reduces the need for additional support and protective structures during installation, making it suitable for a variety of complex installation scenarios.

[0015] The integrated communication interface design allows power supply and communication to be completed through a single cable, and supports Bluetooth wireless communication, simplifying the installation process and reducing the cost of deployment and repeated installation; the wide-range power supply design is compatible with domestic power supply environments, eliminating the need for additional step-down equipment and further saving costs.

[0016] The domestically produced UHF RFID module is compatible with the SDK interface of imported readers, facilitating rapid replacement; at the same time, it can meet the requirements of the national standard UHF RFID protocol through firmware upgrades, making it suitable for various special application scenarios in the domestic market.
