[0027] As shown in the figure, the device for collecting and storing fresh fecal samples from wild animals comprises a housing 1, a collection tool housed within it, a mobile device, a label printer 11, a controller, and a power supply system located at the bottom of the housing 1. The power supply system is connected to the cooling system, temperature sensor 5, and controller to power the equipment. The housing 1 is hingedly attached to a lid 2, integrating the complete set of collection tools and storage. The lid 2 is fixed to the housing 1 with fasteners and has a handle on top for moving the housing 1.

[0028] like Figure 2 As shown, the box body 1 is provided with a storage chamber 3 and a refrigeration chamber 4. The storage chamber 3 is provided with a plurality of storage compartments for storing collection tools, including disposable PE gloves, a collection spoon 8 and a cryopreservation tube 13. Figure 5 As shown, the collection spoon 8 is made of plastic or metal, and includes a rod and a collection head 9 detachably connected to the end of the rotating rod. The collection head 9 can be connected to the rod by threads or buckles. Before installing the collection head 9, a disposable collection sleeve 10 is first placed on the collection head 9, and then the rod is installed so that the disposable collection sleeve 10 is fixed at the connection between the rod and the collection head 9. After collecting feces, the disposable collection sleeve 10 is removed and thrown into a garbage chamber 14 for storing waste.

[0029] like Figure 3 As shown, the refrigeration chamber 4 is used to refrigerate samples. A temperature sensor 5 is provided in the refrigeration chamber 4. A closing door is provided on the top. A digital temperature display screen 7 is provided on the closing door. The temperature sensor 5 is connected to the digital temperature display screen 7 to display the internal temperature of the refrigeration chamber 4. The side wall of the refrigeration chamber 4 is provided with a heat conducting plate 18. A plurality of cooling fins 17 are attached to the outside of the heat conducting plate 18. The cold end of the cooling fin 17 is connected to the heat conducting plate, and the hot end is connected to the radiator 19. A cooling fan 20 is provided on one side of the radiator 19. The refrigeration system is provided at the rear end of the refrigeration chamber 4, and a cooling louver 6 is provided on the outside of the rear end surface of the box body 1. Figure 4 shown.

[0030] In order to ensure that the cryopreservation tube 13 is placed in a limited position in the cold storage chamber 4 and prevent it from shifting, a limiting rack 15 is set in the cold storage chamber 4. The limiting rack 15 is a double-layer structure, with an installation opening on the upper layer and a limiting groove 16 on the lower layer for limiting the placement of the cryopreservation tube 13. After the cryopreservation tube 13 is placed on the limiting rack 15, the installation opening and the limiting groove 16 limit the bottom and top of the cryopreservation tube 13.

[0031] The controller not only controls the operation of the equipment but also serves as a data recording system. It is necessary to ensure that it has sufficient storage space, data processing capabilities and user interface to meet the needs of data recording, so that data can be uploaded and labels can be printed through mobile devices. An interface module, a data storage module, a data management module, a label generation module, a printing control module, a GPS module and a temperature control module are provided in the controller. Interface module: used to communicate with mobile devices to realize data upload and download functions. Data management module: used to manage data storage, backup and query, to ensure information security and timely and reliable data recording. Label generation module: generates labels based on sample information for subsequent printing. Printing control module: used to control the operation of the label printer and send the generated label information to the printer for printing. The GPS module is used for positioning and to record the location information and driving trajectory during sampling. Temperature control module: connected to the refrigeration system and temperature sensor, used to control the temperature of the refrigeration chamber.

[0032] The controller stores the sampler's driving trajectory information obtained from the GPS module along with the sample information for subsequent query and monitoring. It also connects to a computer for data exchange. The ability to scan a barcode or QR code to view the sampler's driving trajectory completes the sampling information recording module and enhances its functionality. The integration of these structures will improve information traceability and management efficiency during the sampling process, while also helping to ensure data accuracy and authenticity.

[0033] The mobile device is equipped with information management software for managing sample information, recording, querying, exporting and other operations to improve information management efficiency. The user enters and edits the relevant information of each sample, such as sampling time, location, longitude and latitude, etc. through the mobile device, and transmits the information to the controller for storage for subsequent extraction and processing. The relevant QR code or barcode is generated and the label is printed based on the label printer 11 and affixed to the cryopreservation tube 13. In order to prevent the weak network signal from affecting the label generation during the collection process, the information management software is set to an offline working mode to support offline work. It can be used to transmit data to the controller in an offline environment. The connection between the controller and the mobile device and the label printer is achieved through a wired connection or Bluetooth.
