Metal tooth detection and locating
Methods and systems for tracking heavy machine teeth. One system includes a heavy machine tooth configured to be mounted on a bucket of a heavy machine, an active RFID tag coupled to the heavy machine tooth to move with the tooth, and an RFID reader configured to read data from the RFID tag, The RFID reader is further configured to provide an indication regarding the location of the tooth when the tooth separates from the bucket based on the data read from the RFID tag and provide diagnostic information regarding the heavy machine tooth based on the data read from the RFID tag.
1. A system comprising:
a heavy machine tooth;
a mounting bracket coupling the heavy machine tooth to a bucket of a heavy machine, the mounting bracket separate from the bucket of the heavy machine and having a first end attachable to the heavy machine tooth and a second end attachable to the bucket of the heavy machine;
an RFID tag positioned between the mounting bracket and the heavy machine tooth, the RFID tag coupled to the heavy machine tooth to move with the heavy machine tooth when the tooth is separated from the bucket; and
an RFID reader configured to receive at least one signal from the RFID tag and detect separation of the heavy machine tooth from the bucket based on the at least one signal received from the RFID tag,
wherein the at least one signal includes a first signal from the RFID tag when the heavy machine tooth is separated from the bucket and a second signal from the RFID tag when the heavy machine tooth is coupled to the bucket, wherein a strength of the first signal is the same as a strength of the second signal.
2. The system of claim 1 , wherein the RFID tag is an active tag.
3. The system of claim 1 , wherein the at least one signal includes a first signal received with the RFID reader from the RFID tag when the heavy machine tooth is separated from the bucket and a second signal received with the RFID reader from the RFID tag when the heavy machine tooth is coupled to the bucket, wherein the first signal is different than the second signal.
4. The system of claim 1 , wherein the RFID tag is mounted to an end of the heavy machine tooth and the end of the heavy machine tooth is inserted into the mounting bracket to couple the heavy machine tooth to the bucket.
5. A system comprising:
a heavy machine tooth; and
an RFID tag positioned between the heavy machine tooth and a mounting bracket, the RFID tag coupled to the heavy machine tooth to move with the heavy machine tooth when the tooth is separated from the bucket, the mounting bracket separate from the bucket and having a first end attachable to the heavy machine tooth and a second end attachable to the bucket of the heavy machine,
wherein detection of at least one signal from the RFID tag with an RFID reader indicates separation of the heavy machine tooth from the bucket,
wherein the at least one signal includes a first signal from the RFID tag when the heavy machine tooth is separated from the bucket and a second signal from the RFID tag when the heavy machine tooth is coupled to the bucket, wherein a strength of the first signal is the same as a strength of the second signal.
6. The system of claim 5 , wherein the RFID tag is an active tag.
7. The system of claim 5 , wherein the at least one signal includes a first signal received with the RFID reader from the RFID tag when the heavy machine tooth is separated from the bucket and a second signal received with the RFID reader from the RFID tag when the heavy machine tooth is coupled to the bucket, wherein the first signal is different than the second signal.
8. The system of claim 5 , wherein the RFID tag is mounted to an end of the heavy machine tooth and the end of the heavy machine tooth is inserted into the mounting bracket to couple the heavy machine tooth to the bucket.
9. A system comprising:
a mounting bracket coupling a heavy machine tooth to a bucket of a heavy machine, the mounting bracket separate from the bucket of the heavy machine and having a first end attachable to a heavy machine tooth and a second end attachable to the bucket of the heavy machine; and
an RFID tag positioned between the mounting bracket and the heavy machine tooth, the RFID tag coupled to the heavy machine tooth to move with the heavy machine tooth when the tooth is separated from the bucket,
wherein detection of at least one signal from the RFID tag with an RFID reader indicates separation of the heavy machine tooth from the bucket,
wherein the at least one signal includes a first signal from the RFID tag when the heavy machine tooth is separated from the bucket and a second signal from the RFID tag when the heavy machine tooth is coupled to the bucket, wherein a strength of the first signal is the same as a strength of the second signal.
10. The system of claim 9 , wherein the RFID tag is an active tag.
11. The system of claim 9 , wherein the at least one signal includes a first signal received with the RFID reader from the RFID tag when the heavy machine tooth is separated from the bucket and a second signal received with the RFID reader from the RFID tag when the heavy machine tooth is coupled to the bucket, wherein the first signal is different than the second signal.
12. The system of claim 9 , wherein the RFID tag is mounted to an end of the heavy machine tooth and the end of the heavy machine tooth is inserted into the mounting bracket to couple the heavy machine tooth to the bucket.
