为了满足低功耗、低成本、远距离无线传输的要求，提出了一种有源射频识别( RFID)标签结构。通过软硬件的设计，解决了无源标签识别距离短、数据传输不稳定的问题。硬件电路采用 STC10L16XE 芯片作为控制芯片，射频部分采用低成本、低功耗的CC2500芯片。测试结果表明，该标签结构具有抗干扰性好、功耗低、可靠性高、扩展方便等优点，具有一定的实用价值。%In accordance with the requirements of low power consumption, low costs and long distance wireless transmission, the active RFID tag structure is proposed. Through software and hardware design, the demerits of passive tag identification, e. g. , short distance and unstable transmission are overcome. In the design, the hardware circuitry is composed of STC10L16XE as the control chip, and the low power consumption and low cost chip CC2500 as the radio frequency section. The test results show that the tag structure features many advantages, such as good anti-interference capability, low power consumption, high reliability and ease extensibility, etc. , so it possesses certain practical values.
