The invention provides a data acquisition method, system and equipment of an RFID (Radio Frequency Identification Device) sensor tag. The method comprises the steps that a card reader generates an air interface command corresponding to a GB / T28925 protocol according to an initialization command and a configuration command sent by an upper computer platform, the air interface command is sent to a label, and the label is initialized and configured; performing deployment and network access operation on the initialized and configured label to establish wireless communication between the label and the gateway; and the label responds to a data acquisition command sent by the gateway, acquires sensor data, and feeds back the sensor data and label ID information to the gateway according to the time slot number. In this way, on the premise of being compatible with the national standard GB / T 28925-2012 protocol, the batch or rapid acquisition function of sensor data can be achieved in a command adding mode, and the problem that the sensor data cannot be rapidly acquired in batches due to the fact that sensor RFID tags are carried in the GB / T 28925 national standard protocol is solved.
Description
technical field [0001] The present invention generally relates to the field of sensor data collection, and more specifically, to a data collection method, system and device for RFID sensor tags. Background technique [0002] RFID is radio frequency identification, which is a technology that automatically identifies objects and obtains relevant data through the spatial coupling principle of radio frequency signals. RFID is divided into low frequency (LF), high frequency (HF), ultra high frequency (UHF), and microwave (MW) according to different application frequencies. The corresponding representative frequencies are: low frequency below 135KHz, high frequency 13.56MHz, ultra high frequency High frequency 860M~960MHz, microwave 2.4G, 5.8G. RFID is divided into passive RFID and active RFID according to the energy supply method. [0003] The GB / T 28925-2012 protocol standard stipulates the physical layer, data link layer, tag storage area structure, tag state transfer, reader...
