[0086] In order to describe the operation process of this method more clearly, the following examples and attached Figure 4 The present invention is described in detail.
[0087] Assume that there are 6 sensor tags, and their binary ID numbers are 12 digits, and they are queried in the form of a hexadecimal tree, that is, hexadecimal. The binary ID numbers and hexadecimal ID numbers of the six sensor tags are as follows:
[0088] Sensor number one label: 001001100011 (binary), 263 (hexadecimal);
[0089] Sensor number two label: 001001001010 (binary), 24A (hexadecimal);
[0090] Sensor No. 3 label: 101100101001 (binary), B29 (hexadecimal);
[0091] Sensor No. 4 label: 110111000001 (binary), DC1 (hexadecimal);
[0092] Sensor No. 5 label: 001001000111 (binary), 247 (hexadecimal);
[0093] Sensor number six label: 110111001000 (binary), DC8 (hexadecimal).
[0094] The execution steps of this method in this example are as follows:
[0095] 1. The reader sends an initializ...
