Firstly, uniformly manufacturing parts such as a vertical fixed square column 7, a transverse pressing plate 8, an upper top spring 9, a rotary spanner 11, a U-shaped support 13, a lifting transverse plate 21, an L-shaped hook 22 and the like in a factory, wherein the parts are free from manufacturing difficulty, after the key preparation is finished, the parts are assembled, the vertical fixed square column 7 and the transverse pressing plate 8 are directly welded according to the diagram, a small section of cylindrical external thread can be arranged at the bottom end of the vertical fixed square column 7, a groove with internal thread is arranged at the center of the transverse pressing plate 8, then the cylindrical external thread is screwed into the groove of the transverse pressing plate 8 to be matched with the internal thread, in summary, the parts are all known technologies, the upper top spring 9 is firstly sleeved on the vertical fixed square column 7, then the U-shaped support 13 is sleeved on the upper top spring 9 of the vertical fixed square column 7, then the lifting transverse plate 21 is sleeved, the top end of the U-shaped support 13 extends into the inward-outward chute 14 at the bottom of the lifting transverse plate 21, then the vertical fixing square column 7 is directly welded at the bottom of the supporting frame 1, the connection mode of the vertical fixing square column 7 and the bottom of the supporting frame 1 can be the other one, namely, when in manufacture, a small section of nut with internal threads is welded at the upper end of the vertical fixing square column 7, the outer diameter of the nut is smaller than the outer edge of the vertical fixing square column 7, then when in installation, holes are drilled at the installation position of the corresponding supporting frame 1, the aperture is slightly larger than the nut with internal threads at the upper end of the vertical fixing square column 7 and smaller than the outer edge of the vertical fixing square column 7, so that the nut extends into the through hole, but the upper end of the vertical fixing square column 7 just props against the bottom edge of the through hole from top to bottom, then bolts 24 extend into and pass through, and the lower ends of the bolts 23 are matched with the nuts in a threaded manner, and gradually fixing tightly along with twisting the spinning, and finishing the fixing. There are, of course, other ways, which are not described in detail herein. The manufacturing process of the refrigerant clamping groove 3 is directly entrusted to the manufacturer to customize production according to the requirements, and the manufacturing difficulty is not low-!
As shown in fig. 2, the equipment is composed of two parts, namely an internet of things logistics box 5 with temperature measurement, heat preservation and alarm functions and a quick replacement structure 6 capable of realizing quick replacement of refrigerants, wherein the quick replacement structure is a structure capable of being arranged in the internet of things logistics box and being taken out from the internet of things logistics box;
As shown in fig. 1, the quick replacement structure 6 is composed of a support frame 1, a refrigerant 2 and a refrigerant clamping groove 3, the refrigerant clamping groove 3 is fixed on the support frame 1, the refrigerant 2 is detachably clamped at the refrigerant clamping groove 3, and a storage space 4 is formed among the refrigerant 2.
The refrigerant clamping grooves 3 are uniformly distributed on the supporting frame 1, so that when the refrigerator is used, the refrigerant can be uniformly distributed around the logistics box, and the storage space 4 is reserved in the middle.
The other form of the clamping groove is that the clamping groove is provided with anti-slip textures, so that the refrigerant is fixed on the clamping groove through friction force to realize connection with the supporting frame. Through the standardized refrigerant replacement device, the failed refrigerants can be replaced rapidly, and the defects of low efficiency and uneven cooling caused by the fact that the refrigerants are placed one by one are avoided.
By utilizing the refrigerant management method based on the prediction algorithm implemented by the refrigerant management equipment based on the prediction algorithm,
When the refrigerants are replaced, an express delivery person can take out all the failed refrigerants from the internet of things logistics box 5 at one time in a mode of lifting the supporting frame 1, and then put in another supporting frame carrying the effective refrigerants, so that the refrigerants are quickly replaced; the thing networking logistics box that has temperature measurement, heat preservation, alarming function that supporting use will keep warm and whole temperature detection alarm in transit.
The refrigerant management flow during transportation is as follows:
Firstly, using a temperature measurement module through an internet of things logistics box, and measuring the temperature in the internet of things logistics box in the whole process;
Secondly, uploading temperature information to a server side in real time through a communication module (a narrow-band internet of things module and the like);
thirdly, the server side predicts according to the current temperature, the local weather, the historical temperature, the article type and other data through a prediction algorithm (a machine learning method or a traditional statistical method), selects an optimal refrigerant replacement scheme and judges whether replacement is needed or not;
Fourthly, the prediction result is transmitted back to the internet of things logistics box through the communication module, if the refrigerant does not need to be replaced, the temperature measurement is continued, and if the refrigerant needs to be replaced, the internet of things logistics box starts an alarm;
And fifthly, the logistics box with the refrigerant failure can be assisted by the alarm function, and the failed refrigerant is replaced after the alarm is heard by the courier. Under the premise of ensuring the quality of the articles in the box, the weight of the refrigerant is optimized due to algorithm optimization, and the transportation cost is greatly reduced.
The prediction algorithm in the step (III) is as follows:
Wherein T is the time length of the refrigerant to be replaced under the current transportation condition, T is the current temperature, w is the local weather, h is the historical temperature, s is the article type, i is the ith data meeting the current calculation condition, n is the total number of data meeting the current calculation condition, a, b, c, d is the weight coefficient of the corresponding factors of the current temperature, the local weather, the historical temperature and the article type respectively.
When the intelligent logistics box is used in small Zong Leng-chain transportation, a logistics company with the intelligent logistics box is used for packing the articles into the paper box after a sender pays for sending, and the paper box is filled into an intelligent logistics box which is placed with a quick-change structure carrying a proper amount of refrigerant. And then carrying out loading transportation like ordinary express delivery. In the transportation process, the server side can remind logistics personnel to replace required refrigerants when the logistics boxes pass through a specific transfer station according to the environmental conditions and logistics states. After the logistics box filled with the articles reaches the delivery station, the delivery is carried out by the courier. And (5) recycling the box and the refrigerant after delivering the article to a receiver for the next use.
Profit mode
Companies with the set of refrigerant management methods and apparatus are profitable by renting boxes to logistics companies and providing data services. The logistics company pays deposit to the company holding the box and then takes the box, and the box is stored by the logistics company. The case does not collect rent when not participating in commodity circulation, only collect rent when the case carries article, needs temperature measurement and upload data.
Profit = lease deposit × annual interest rate + daily lease rate × average lease day per year-case manufacturing cost/case life years
* Here, refer to profit and manufacturing cost of a box.
