Embodiment 1
[0076] Such as figure 1 As shown, an online monitoring method for the shedding of a leaky cable sling includes the following steps:
[0077] A. Collect the location information of the spreader and store it by number; each spreader has a unique number;
[0078] B. Implant the RFID tag 1 on the spreader, correlate the information of the RFID tag 1 with the location information of the spreader and build the database of the spreader; since each RFID tag 1 has a fixed and unique code, the spreader and RFID Unique relationship between tags 1;
[0079] The specific process is:
[0080] b1: First place the RFID tag T i Implant spreader A i , RFID tag T i Has a unique fixed code, i is an integer;
[0081] b2: the RFID tag T i The coding information and the corresponding spreader A i associated with location information;
[0082] b3: storage of coded information and location information associated with step b2;
[0083] C. The RFID reader-writer transmits the RFID identificati...
Embodiment 2
[0122] Such as Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the 3 sections L of the leaky cable to be monitored MN The number of corresponding monitoring units is two, and the two monitoring units are respectively connected to the 3-section L of the leaky cable to be monitored MN The two ends of the leaky cable, that is, replace the matching terminal at the end of the 3-section leaky cable in the embodiment with the same monitoring unit as the first end of the 3-section leaky cable to be monitored. This setting method can effectively extend the length of the 3-section leaky cable that can be monitored. , which in turn can be applied to the monitoring of longer tunnels.
[0123] As one of the core technologies of the Internet of Things, RFID technology is widely used in our daily life. A general RFID system consists of a reader (including a radio frequency module), a device covering radio frequency signals (usually an antenna) and an RFI...
