[0023] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0024] As shown in the accompanying drawings, Figures 1-7 The utility model relates to a kind of sensing terminal for prefabricated food quality and safety traceability, including temperature measurement chip module 1, antenna module 2, chip shell 3, extension belt 4.

[0025] The temperature measurement chip module 1 is RFID temperature measurement chip, adopt market product, and the specific product form is PCB board.

[0026] The temperature measurement chip module 1 is arranged in chip shell 3, and extension belt 4 is arranged on chip shell 3, antenna module 2 is arranged at the end of extension belt 4, antenna module 2 and temperature measurement chip module 1 are connected by wire, wire and antenna module 2 are arranged in extension belt.

[0027] Further, to better signal transmission efficiency, disc-shaped wide part 41 is arranged at the end of the extension belt 4, and the antenna module 2 is arranged in the disc-shaped wide part 41. The antenna module 2 includes two groups of symmetrically arranged bent antennas.

[0028] Double-sided adhesive is provided on the back of the disc-shaped wide portion 41 and the chip casing 3.

[0029] Furthermore, since the chip casing 3 is placed inside the turnover box, in order to prevent the pre-cooked food ingredients and finished product packaging bags from scratching the edge of the chip casing 3, the edge of the chip casing 3 is chamfered and its thickness is relatively thin.

[0030] Specific appendix Figure 1 , 2 As shown, the chip casing 3 is trapezoidal in shape, with a larger diameter on the side (back side) where the extension strip is located. The other side has multiple through holes 31, and a waterproof sticker 32 is placed on the inner side of the side containing the through holes. The through holes 31 primarily improve the sensor's sensitivity and timely response, while the waterproof sticker 32 prevents external impurities and water from entering the interior. (See attached image) Figure 3 The outer casing of the chip 3 is rectangular.

[0031] The aforementioned sensor terminal C can be as shown in the attached figure. Figure 4 The chip casing 3 is placed inside the turnover box Z, with the extension strap 4 placed outside the box and attached to the outside of the box.

[0032] The RFID reader D can read data from multiple sensor terminals simultaneously. The RFID reader D uses commercially available products.

[0033] Appendix Figure 5 The diagram illustrates a system application scenario where the sensor terminal is placed inside a turnover box and can be placed along with the turnover box in trucks or warehouses in the logistics process. The sensor terminal can also be placed directly in the factory. Data from the sensor terminal can be collected through an RFID reader D. The RFID reader can be fixed in one place or a portable product can be selected for manual inspection and data reading.

[0034] In practical experience at our partner manufacturers, we found that when reading and writing to the sensor terminals of turnover boxes is required in certain stages, the same sensor terminal can be read and written multiple times due to the close proximity of the turnover boxes. To solve this problem, as shown in the attached document... Figure 6 , 7 As shown, the applicant provides a reading and writing auxiliary device for a sensor terminal. The auxiliary device is used in conjunction with a conveyor belt and includes a limiting component D1 and a reading device frame D2. The reading device frame D2 is used to place the RFID reading terminal D, so that the RFID reading terminal D is located at a preset height above the conveyor belt.

[0035] The limiting component D1 is positioned at the front of the reading device frame D2 near the feed end to limit the position of the turnover box on the conveyor belt, so that it is distributed at a preset interval, reducing mutual interference during subsequent reading and writing.

[0036] The limiting assembly D1 includes a limiting support D11, two groups of limiting rod rotating rod units D12 arranged oppositely, and a driving assembly D13. The limiting support D11 is fixed on the ground and forms a supporting surface under the conveying belt. The limiting rod rotating rod units D12 are arranged on both sides of the conveying belt and are arranged oppositely. The bottom parts are rotatably arranged on the limiting support D11 through bearings. The limiting rod rotating rod unit D12 includes a vertical rod D121, a baffle D122, and a pushing gear D123. The vertical rod D121 passes through the limiting support D11 through a through hole. Bearings are arranged at the through hole to rotatably arrange the vertical rod D121 on the limiting support D11. The baffle D122 is fixed on the top of the vertical rod D121. The pushing gear D123 is arranged on the bottom of the vertical rod D121.

[0037] The driving assembly D13 includes a driving motor D131, a chain wheel driving wheel unit D132, and a chain D133. The chain wheel driving wheel unit D132 includes two gears arranged in an up-down manner, which are a driving gear meshing with the pushing gear D123 and a chain wheel meshing with the chain, respectively. The two gears are fixed on a gear shaft. The gear shaft is rotatably connected to the limiting support D11 through a bearing. The output shaft of the driving motor D131 is connected to the gear shaft of the chain wheel driving wheel unit D132. In this way, the two baffles D122 limit the turnover boxes on the conveying belt.

[0038] It should be noted that, unless otherwise clearly specified and limited, the terms such as "mounting", "connecting", "connecting", "fixing", "arranging" and the like should be understood in a broad sense. For example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication between two elements or the interaction relationship between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
