AI Technical Summary

Benefits of technology

This technology allows for easy access by accessing different types of wireless communication devices (WCD) with unique identification codes called Radio Frequency Identifiers or tags that store important details about them like their manufacturer's branding material used on these WCards. It also includes features such as secure encryption techniques and efficient error correction methods when transmitting signals between two electronic systems through this system. Overall, it provides an effective way to manage multiple networks connected together over wired connections without having to manually input any specific identifying code into each device individually.

Problems solved by technology

This patents describes different technical methods that use radio waves instead of traditional means like magnetic induction to track objects accurately over great distances. These techniques include radar, near field communications, infrared imagery, laser scanning, ultrasonics, etc., each having its own benefits and drawbacks compared to existing approaches. However, these new advances make them more effective when applied indoors due to factors like limited installation locations and lower signal strength levels.

Abstract

The invention discloses a high-frequency multi-protocol high-power reader-writer for radio frequency identification and belongs to technologies in the radio frequency identification field. The reader-writer comprises a radio frequency base station circuit, a microcontroller and a turning circuit, wherein the tuning circuit is connected with the radio frequency base station circuit, and an antennais connected to the tuning circuit; a first access and a second access are connected between the tuning circuit and the radio frequency base station circuit; the first access comprises a first demodulating circuit and a first amplifying circuit which are connected in series; the second access comprises a second demodulating circuit and a second amplifying circuit which are connected in series; anda radio frequency signal generated by the radio frequency base station circuit is sent out by the antenna after passing through the tuning circuit, and the signal received by the tuning circuit is transmitted to the radio frequency base station circuit through the first access or the second access. The technical scheme has the advantages that functions of the reader-writer are highly integrated,the reader-writer can read and write radio frequency cards adopting a TYPE A protocol and a TYPE B protocol, and the reader-write is high in extensibility and adaptability.
