For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0056] like Figure 1 and Figure 2 As shown, a reagent cold chain transportation tracking and positioning system includes a reagent cold chain transportation carrier 19 and a wireless tracking and positioning platform 17;

[0057] The reagent cold chain transport carrier 19 is provided with a reagent box set 14 and a motion correction module;

[0058] The reagent box set 14 is provided with a plurality of cold chain reagent boxes 1, and the plurality of cold chain reagent boxes 1 can be connected with the wireless tracking and positioning platform 17 by signal and provide location information, and the relative positions of the cold chain reagent boxes 1 in the reagent box set 14 are fixed, and the positions of the reagent box set 14 and the reagent cold chain transport carrier 19 are fixed;

[0059] The motion correction module can be connected to the wireless tracking and positioning platform 17 by signal and provide location information. The motion correction module is fixed at the center of the reagent box collection 14. The motion correction module can reciprocate on the reagent cold chain transport carrier 19 with a set trajectory and period.

[0060] The purpose of this design is to set up a reagent cold chain transportation tracking and positioning system consisting of a reagent box collection and a wireless tracking and positioning platform, in which the reagent box collection can provide the necessary information of the reagent box or reagent kit that needs to be tracked and positioned. In theory, in scenarios where GPS or Beidou satellite positioning cannot be used, positioning can be completed by transmitting wireless signals to the wireless tracking and positioning platform. The introduction of the motion correction module, because its position with the reagent box collection is fixed, and the reciprocating motion with a predictable and fixed trajectory and period is imposed, the wireless tracking and positioning platform can correct the position of the reagent box collection based on the position of the motion correction module, greatly improving the overall positioning accuracy. It solves the problem that the existing technology needs to consider factors such as poor signal coverage during long-distance transportation, such as long tunnels, or complex multi-level scenes, and the traditional positioning method cannot be well positioned, or the positioning error is large.

[0061] In this embodiment, in order to complete tracking and positioning, the location information provided by the cold chain reagent box 1 to the wireless tracking and positioning platform 17 includes the reagent box number, the current three-dimensional coordinates of the reagent box, the RFID tag of the reagent box in the reagent box, the reagent box signal transmission power and the reagent box transmitting antenna gain.

[0062] At the same time, the location information provided by the motion correction module to the wireless tracking and positioning platform 17 includes the motion correction module number, the current three-dimensional coordinates of the motion correction module, the moving trajectory of the motion correction module, the moving speed of the motion correction module, the motion correction module signal transmission power and the motion correction module transmission antenna gain.

[0063] like Figure 3 and Figure 4 As shown, a placement cavity 4 and a signal transceiver module 6 are provided in the cold chain reagent box 1. The placement cavity 4 is provided above the signal transceiver module 6. The placement cavity 4 can be used to place a reagent kit fixing mechanism;

[0064] The signal transceiver module 6 can be connected to the wireless tracking and positioning platform 17 by signal.

[0065] At the same time, if Figure 5 , Figure 6 and Figure 7 As shown, the reagent kit fixing mechanism includes an upper end portion 2, a lower end portion 5 and a reagent cartridge 3;

[0066] One end of the reagent cartridge 3 is connected to the upper end 2, and the other end of the reagent cartridge 3 is connected to the lower end 5. The reagent cartridge 3 can hold a reagent kit 8;

[0067] The lower end portion 5 can be inserted into the bottom of the placement cavity 4;

[0068] A portion of the upper end portion 2 is located outside the placement cavity 4, and the cross-sectional dimensions of the upper end portion 2 and the lower end portion 5 are larger than the cross-sectional dimensions of the reagent cartridge 3;

[0069] A cartridge door 7 is provided on one side of the reagent cartridge 3, a reagent cartridge containing chamber 10 is provided in the reagent cartridge 3, a plurality of partitions 12 are provided in the reagent cartridge containing chamber 10, and the plurality of partitions 12 divide the reagent cartridge containing chamber 10 into a plurality of chambers from top to bottom, each chamber can hold a reagent cartridge 8, and each chamber is provided with a temperature sensor 11;

[0070] The surface of the reagent box 8 is attached with an RFID tag 9 , and both the RFID tag 9 and the temperature sensor 11 can be connected to the signal transceiver module 6 for signal transmission.

[0071] The purpose of such a design is, on the one hand, to provide necessary protection for the reagent kit fixing mechanism by arranging a placement cavity in the cold chain reagent box so as to be used for placing the reagent kit fixing mechanism.

[0072] On the other hand, a reagent box fixing mechanism consisting of an upper end, a lower end and a reagent cartridge is used to protect the reagent box therein, that is, double protection is achieved through the above structure.

[0073] At the same time, partitions are provided in the reagent cylinder so that multiple reagent kits can be placed therein from top to bottom, and RFID tags are affixed to the reagent kits so that the positions of the reagent kits can be located in real time, so that after the reagent cold chain transport carrier is positioned, a specific type of reagent can be positioned according to the RFID tag.

[0074] Furthermore, the partitions are arranged to divide the reagent kit containing cavity into a plurality of cavities, and a temperature sensor is arranged in each cavity, so that the temperature of each reagent kit can be monitored more accurately.

[0075] It should be pointed out that, in a specific implementation, those skilled in the art can set up a layered cooling mechanism in the cold chain reagent box, so that the reagent kits located in different cavities can obtain different cooling temperatures.

[0076] like Figure 8 As shown, the outer peripheries of a plurality of cold chain reagent boxes 1 in a reagent box set 14 are connected via a connecting frame 13 , and the reagent box set 14 is a cylinder with a regular geometric shape.

[0077] It should be pointed out that the purpose of such design is that, since a regular column structure is set up, such structure can usually be a triangular prism, a quadrangular prism or a cylindrical structure, so that the position of each cold chain reagent box is easier to calculate compared with the motion correction module, thereby reducing the error caused by the irregular structure.

[0078] It should also be pointed out that since the upper end is higher than the cold chain reagent box, when stacking, a gasket with a fixed height is required to prevent the cold chain reagent boxes on the upper and lower layers from affecting each other.

[0079] like Figure 2 As shown, it also includes a signal relay tower 18, and the signal relay tower 18 can transmit signals between the reagent cold chain transport carrier 19 and the wireless tracking and positioning platform 17.

[0080] The purpose of this design is that in some usage scenarios, such as a section of the Zhongnanshan Tunnel in the Qinling Mountains, the entire tunnel is directly connected to the reagent box assembly 14 and the motion correction module with the wireless tracking and positioning platform 17, which is affected by the environment and has a large error. Therefore, a signal relay tower 18 can be selected to relay the sent and received signals to extend the entire signal coverage range.

[0081] It should also be pointed out that in the specific implementation scenario, this embodiment also provides a positioning method, that is, the wireless tracking and positioning platform is located in a scenario where the orientation can be determined. Simply put, positioning can be completed using GPS or Beidou, and then the wireless tracking and positioning platform 17 receives the signals sent by the cold chain reagent box 1 and the motion correction module to determine the position of the reagent cold chain transport carrier 19.

[0082] like Figure 2 As shown, the motion correction module includes a fixing base 15 and a signal transceiver antenna 16;

[0083] The signal transceiver antenna 16 is disposed on the fixing base 15, and the signal transceiver antenna 16 can be connected to the wireless tracking and positioning platform 17 by signal;

[0084] Driven by the power structure, the fixing seat 15 can perform reciprocating motion at a set trajectory and period.

[0085] It should be pointed out that a motion correction module is arranged on the top of the reagent cold chain transport carrier 19. In this scheme, its running trajectory is circular motion. Since the whole working principle is approximate, circular motion is assumed to be used for explanation. At the same time, an annular groove 20 is also arranged thereon. The fixed seat 15 enables the signal transceiver antenna to perform circular motion with the cooperation of the motor and the rotating shaft.

[0086] In this embodiment, a reagent cold chain transportation tracking and positioning method is also provided, which is implemented based on the reagent cold chain transportation tracking and positioning system and applied to the cold chain reagent box 1 end. The method includes the following steps:

[0087] A1. The cold chain reagent box 1 collects the information of the RFID tag 9 on the reagent kit 8 placed in the cavity 4 and the temperature information transmitted by the temperature sensor 11;

[0088] A2. Package the information obtained in A1 with the reagent box number, the current three-dimensional coordinates of the reagent box, the reagent box signal transmission power and the reagent box transmission antenna gain into a reagent box data packet;

[0089] A3. The signal transceiver module 6 sends a reagent box data packet to the wireless tracking and positioning platform 17.

[0090] In this embodiment, a reagent cold chain transportation tracking and positioning method is also provided, which is implemented based on the reagent cold chain transportation tracking and positioning system and applied to the motion correction module end. The method includes the following steps:

[0091] B1. The fixed seat 15 reciprocates around the reagent tank set 14 in a set trajectory and cycle driven by the power structure;

[0092] B2 motion correction module number, motion correction module current three-dimensional coordinates, motion correction module moving trajectory, motion correction module moving speed, motion correction module signal transmission power and motion correction module transmitting antenna gain packaged as a correction data packet;

[0093] B3. The signal transceiver antenna 16 sends a correction data packet to the wireless tracking and positioning platform 17.

[0094] In this embodiment, a reagent cold chain transportation tracking and positioning method is also provided, which is implemented based on the reagent cold chain transportation tracking and positioning system and applied to the wireless tracking and positioning platform 17. The method includes the following steps:

[0095] C1 wireless tracking and positioning platform 17 receives the reagent box data packet and the correction data packet;

[0096] C2. The wireless tracking and positioning platform 17 initially locates the reagent cold chain transport carrier 19 via the reagent box data packet;

[0097] C3. The wireless tracking and positioning platform 17 corrects the initial positioning position through the correction data packet to complete the reagent cold chain transportation tracking and positioning.

[0098] In a specific implementation scenario, this embodiment provides an implementable solution, and those skilled in the art may implement it with reference to this embodiment:

[0099] When the wireless tracking and positioning platform receives the reagent box data packet, it will disassemble the data in it, determine the data of each reagent box according to the reagent box number information, and then use the following formula to obtain the specific distance d between the wireless tracking and positioning platform and a certain numbered reagent box received, completing the initial positioning:

[0100]

[0101] Among them, α R is the signal gain received by the wireless tracking and positioning platform, α T is the signal gain transmitted by the wireless tracking and positioning platform, n is the path loss index, P T is the reagent box signal transmission power, P R It is the receiving power of the wireless tracking and positioning platform.

[0102] At the same time, when performing calculations, the measurement error caused by a certain numbered reagent box itself can be calculated based on the data collected during the cycle, thereby improving the accuracy of the initial positioning.

[0103] After completing the initial positioning, the wireless tracking and positioning platform processes the correction data packet. Since circular motion is used in this embodiment, the moving trajectory and moving speed of the motion correction module are information such as angular velocity and angle of rotation. At the same time, for the transmission power and.

[0104] First, record and find the maximum value of the signal power of the wireless tracking and positioning platform receiving end within the rotation angle increment of 360° max{P R} and the angle θ obtained after signal decoding R , and by max{P R} According to the above formula, we can calculate the measured distance d between the motion correction module and the wireless tracking and positioning platform. 1 .

[0105] Since the distance between the motion correction module and a certain numbered reagent box is fixed, 2 , and based on the rotation angle θ R and the measuring distance d 1 The specific distance d' between the wireless tracking and positioning platform and a certain numbered reagent box received can be inferred from the motion correction module data.

[0106] The difference between the specific distance d and the specific distance d' is the error value of the entire tracking and positioning system, which is corrected during positioning to ultimately complete the reagent cold chain transportation tracking and positioning.

[0107] It should be pointed out that, since a plurality of cold chain reagent boxes are arranged in the reagent box set in this embodiment, the error value can be further reduced by means of an extended filter during calculation. Since this content belongs to the prior art, it will not be described in detail.

[0108] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
