[0021] The semi-active tag structure of the present invention adopts the mode that the analog part of the tag is powered by the rectifier module, and the digital processing module is powered by the battery. The module is powered, and the digital processing module only enters the working state when the reader reads the tag, that is, when the tag receives the relevant command from the reader, and is in sleep mode with little power consumption most of the time. This power supply method can save the power of the battery to the greatest extent, so that the working life of the tag in the active state is greatly increased, and the ideal state can reach about 10 years.
[0022] The semi-active tag structure of the present invention works in two states according to the relationship between the battery voltage value and the voltage value rectified by the rectifier module. figure 1 The structure diagram of the semi-active tag with figure 2 The structure diagram of the switch built by t...
