[0027] The advantages and features of the present invention will be more clearly understood from the following description and claims.

[0028] This embodiment provides a vibration sensing information rod, which senses the vibrations generated by termites gnawing on wood through the special structure, thereby realizing monitoring of termites.

[0029] For details, please see Figure 1 The vibration sensing information rod comprises: a termite bait body 1, a vibration transmission member 2, a vibration plate 3, a vibration seat 4 and a fixing member 5; a hole 6 is provided in the termite bait body 1, the vibration transmission member 2 is placed in the hole 6, and one end of the vibration transmission member 2 is against the bottom of the hole 6, and the other end of the vibration transmission member 2 is inserted into the bottom of the vibration seat 4 and is tightly attached to the bottom of the vibration seat 4. The bottom of the vibration seat 4 is inserted into the hole 6 and has an interference fit with the hole 6. A protrusion is provided on the opposite surface of the bottom of the vibration seat as a vibration core 7; the vibration plate 3 is placed on the vibration core 7. The fixing member 5 is covered on the top of the vibration plate 3 and is sleeved outside the termite bait body 1.

[0030] The above-mentioned vibration sensing information rod is a complete and compact whole. Its core principle is that when the vibration plate (piezoelectric ceramic plate) is deformed, a certain voltage difference will be generated at two levels due to the piezoelectric effect. This voltage difference is transmitted through the wire for data collection, thereby realizing the detection of termites. Since the vibration generated by termites gnawing is very slight, in order to effectively transmit the vibration, the thickness of the vibration plate does not exceed 0.3mm. It relies on the vibration seat structure to limit the position to ensure that the vibration of the vibration transmission member received by the vibration plate can be converted into its own deformation, rather than the vibration plate as a whole vibrating. In addition, the vibration transmission member and the vibration seat are tightly fitted, and the vibration core and the vibration plate in the middle of the vibration seat are fitted to ensure its vibration conductivity; at the same time, the bottom of the vibration transmission member just touches the bottom of the hole of the termite bait, ensuring that the fitting state of the vibration transmission member and the vibration seat will not separate, and the vibration of the termite bait itself can also be well transmitted to the vibration transmission member, realizing two-level vibration transmission.

[0031] The termite bait in this embodiment can be plant roots, stems and barks, wood, dry branches and fallen leaves, and wood products containing cellulose that termites like, or it can be ordinary wood processed into a rod shape, such as a rectangular or cylindrical shape.

[0032] The vibration seat in this embodiment, please refer to Figure 2 , including an upper receiving plate 401 and a lower slot 402, the upper receiving plate 401 and the lower slot 402 are coaxially fixedly connected. A protrusion is set at the center of the upper receiving plate 401 as a vibration core 7, and the vibration sheet 3 is placed on the vibration core 7 and is located in the upper receiving plate 401. Figure 3 One end of the vibration transmission member 2 is inserted into the lower slot 402 and is in close contact with the bottom of the lower slot 402. The vibration transmission member 2 is a lightweight object that can easily vibrate with the vibration of the termite bait.

[0033] A plurality of fins 8 are disposed around the lower slot 402 . When the lower slot 402 is inserted into the hole 6 of the termite bait body 1 , the fins 8 squeeze the inner wall of the hole 6 , so that the lower slot 402 is fixedly connected to the termite bait body 1 .

[0034] For the fixing member in this embodiment, please refer to Figure 1 and Figure 4 , which includes a signal line connection seat 501, the bottom of which extends downward to form a cavity 9, which matches the upper receiving plate 401 of the vibration seat to provide a vibration space for the vibration plate 3. The periphery of the cavity 9 extends outward to form a sleeve 10, which is sleeved outside the termite bait body 1 and fits tightly with the termite bait body 1.

[0035] Furthermore, the cavity 9 includes an upper cavity and a lower cavity, and the area of ​​the upper cavity is smaller than that of the lower cavity. The lower cavity matches the upper supporting plate of the vibration seat to limit the vibration space of the vibration plate to prevent the vibration plate from not being able to sense the vibration transmitted by the vibration transmission member due to the excessive space.

[0036] A through hole 11 is provided in the signal line connection seat 501 of the fixing member 5 to lead out the signal line on the vibration plate. A sealing silicone pad 12 is embedded in the through hole 11 to protect the vibration space and play a role in waterproofing and dustproofing.

[0037] The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they still fall within the protection scope of the present invention.
