Cold filling process for cold chain transport:
before transportation: the cold chain transport means utilizes the intelligent module to control the cold quantity. On the way of transporting low-temperature goods, before starting, the cold storage plates with proper temperature and proper quantity are installed according to the required temperature of the loaded goods. When the intelligent module starts, the intelligent module is interacted with a display panel (can be pressed or touched) to determine to enter a cold charging mode, and the type and the refrigerating temperature of the phase-change material are input. Because the characteristics of different phase-change materials are different, the intelligent module retrieves the information base and calculates the cold filling early warning temperature according to the type of the phase-change materials. In the operation process, the temperature sensor measures the temperature in the whole process. When the intelligent module detects that the temperature of the goods storage area of the cold chain transport tool is higher than the cold charging early warning temperature, the cold storage plate is ready to be replaced. Firstly, the intelligent module determines the temperature and the number of cold storage plates to be replaced according to the required temperature of goods and the required delivery time; the transport means checks the position of a certain refrigeration station and the storage condition of the cold storage plate with corresponding temperature through communication with the refrigeration station, proposes a cold charging scheme and indicates a path of the cold storage plate. Cold plate information includes, but is not limited to: the cold-charging cabin of the refrigeration equipment can be used for placing L1 cold-storage plates at most, the refrigerating temperature of the cold-storage plates is X ℃, the cold-storage plates which can be used for cold charging currently have L2 blocks (L2 can be equal to L1), and the cold-storage plates which can be used for cold charging currently have M2 blocks. The cold storage bin can be used for containing M1 cold storage plates at most, and the number of the cold storage plates which can be used for cold storage currently is M2 (M2 can be equal to M1). According to the demand and the supply condition to the cold-storage plate, the intelligent module can confirm the quantity of the cold-storage plate of changing and the position of refrigeration station, and at last, the cold-storage plate is changed to going to.
In the transportation process: and finding out the refrigeration equipment with the corresponding temperature grade after reaching the refrigeration station, and opening the bin door to replace the cold storage plate through interaction with the interactive screen of the cold charging bin. The cold charging and cold storage plate changing mode is as follows: the cold storage plates on the transport tool are firstly detached to vacate space, then the bin transmission device is started, the cold storage plates are conveyed one by one from the right door and manually installed on the transport tool, finally the detached cold storage plates are placed into the bin one by one from the left door, and then the transport tool runs according to a planned path.
And (3) determining a path of the cold storage plate replacement: when the cold chain transport means is in the cold charging mode, a cold charging scheme is proposed and the cold storage plate replacing path is indicated to be realized through the transport means intelligent module, and the logic of the part is as follows (corresponding to fig. 6). At the moment, the temperature is defaulted to enter the cold charging early warning temperature, and the scheme of cold charging and cold storage plate replacement is planned. Firstly, inquiring and displaying the number N of cold storage plates required to be replaced in the vehicle and the current temperature, then positioning the nearest refrigeration station, and inquiring the storage condition of the cold storage plates of the station, namely the number of the available cold storage plates at the required temperature. The intelligent module judges whether the number N of cold storage plates required to be replaced in the vehicle can be met by the cold storage plates L2 (located in the cold charging bin) supplied by the current refrigeration station, namely whether L2 is larger than or equal to N or not, and if yes, the cold storage plates are replaced; if the number of the cold storage plates is not met, according to the distance sequence from the cold chain transport means, other three nearest refrigeration stations nearby are newly added, the storage conditions of the cold storage plates of the three refrigeration stations are inquired, the number of the available cold storage plates is respectively L2, L3, L4 and L5, and whether the number N of the cold storage plates needing to be replaced can be met or not is checked. If L2+ L3 is more than or equal to N, the requirement can be met by predicting to replace cold storage plates in two refrigeration stations, interaction with the interactive screen of the cold charging bin is realized after the cold storage plates arrive, the number of the replaced cold storage plates is determined, and the like is realized. If the requirement is not met, other three nearest refrigerating stations nearby are newly added according to the distance between the cold chain transport means and the cold chain transport means. And planning a path for replacing the cold storage plate according to the position of the refrigeration station and the path for conveying after replacing the cold storage plate, and planning to get on the road according to the path.

If M2 is not equal to 0, min { N', M2} is the number of the replaceable cold storage plates of the station, if the number is not 0, the cost of the replacement scheme is compared with the cost of cold storage energy saving, if the number is not 0, the cold storage plates are replaced before, the cold storage plates interact with the interaction screen of the cold storage bin, and the transmission device is started to operate. If not, or M2=0, newly adding other three nearest refrigerating stations near the transport means according to the distance sequence, inquiring the storage conditions of the cold storage plates of the three refrigerating stations, and then checking that the number of the cold storage plates capable of being used for cold storage is M3, M4 and M5 (the positions are gradually far), and then checking whether the number N' of the cold storage plates needing to be replaced can be met. If M '= M3+ M4+ M5=0, abandoning the replacement, if M' ≠ 0, then min { N ', M' } is the number of replaceable cold storage plates for the time, calculating and comparing the cost of the replacement scheme with the cold energy saving cost, and if the min { N ', M' } is not 0, replacing the cold storage plates before; if not, the number of the front refrigeration stations is reduced one by one from the farthest refrigeration station, wherein M ' = M3+ M4, the number of the new cold storage plates to be changed is min { N ', M ' } and whether the new cold storage plates to be changed are 0 is judged, and the replacement is abandoned until a cost-effective scheme is generated or the number is reduced to min { N ', M ' } =0.
