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 bin of the refrigeration equipment can be provided with at most L1 cold storage plates, the refrigeration temperature of the cold storage plates is X ℃, L2 cold storage plates (L2 can be equal to L1) can be used for cold charging at present, and M2 cold storage plates can be used for cold collection at present. The cold-collecting chamber can be used for containing M1 cold-storage plates at most, and M2 cold-storage plates (M2 can be equal to M1) are currently available for cold collection. 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 door to exchange 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 accumulation plates on the transport means are firstly detached to vacate a space, then the cabin transmission device is started, the cold accumulation plates are conveyed one by one from the right door and manually installed on the transport means, finally, the detached cold accumulation plates are put into the cabin one by one from the left door, and then the transport means 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 a cold charging bin) of the current refrigeration station, namely whether L2 is more than or equal to N, and if yes, the vehicle goes to be replaced; if the number of the cold storage plates is not satisfied, according to the distance sequence from the cold chain transport tool, 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 repeated. 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.

Before transportation: sometimes the transport means is returned without cargo or cargo to be stored at low temperature, and at this point the option of recovering the cold is to be selected, i.e. the transport means gives off cold to the refrigeration station. When the vehicle-mounted module of the transport tool receives cold, the vehicle-mounted module can also inquire one or more than one refrigerating station information to form a scheme for replacing the cold storage plate, and meanwhile, whether the scheme for replacing the cold storage plate is cost-effective or not can be judged, and the cold storage plate is replaced after the scheme is cost-effective, so that the cost is saved. The cost of replacing the cold storage plate mainly comprises labor cost and extra driving cost in the process of replacing the cold storage plate. Ideally, the cold accumulation plate is replaced along the way without deviating from the original route.
In the transportation process: when cold storage plates are replaced by cold storage, the cold storage plates with higher temperature are taken out from the right door through the transmission device of the cold storage bin to vacate a space, and then the cold storage plates with lower temperature are unloaded from the transportation tool and are immediately put in from the left door. After which the vehicle returns with the cold storage plates at a higher temperature.

If M2 is not equal to 0, min { N', M2} is the number of replaceable cold accumulation plates of the station, if the number is not 0, the cost of the replacement scheme is compared with the cost of cold accumulation saving, if the value is not 0, the cold accumulation plates are replaced before, the cold accumulation plates interact with an interaction screen of a cold accumulation bin, and a transmission device is started to operate. If the number of cold storage plates is not calculated or the number of the cold storage plates M2 is equal to 0, other three nearest refrigeration stations near the position are newly added according to the sequence of the distance from the transport means, the storage states of the cold storage plates of the three refrigeration stations are inquired, the number of the cold storage plates available for cold storage is respectively found to be M3, M4 and M5 (the positions are gradually changed away), and whether the number N' of the cold storage plates needing to be replaced can be met or not is checked. If M '═ M3+ M4+ M5 ═ 0, abandon the replacement, if M' ≠ 0, min { N ', M' } is the number of cold storage plates that can be replaced this time, calculate and compare the cost and cold energy saving cost of the replacement scheme, if the sum of the cost and min { N ', M' } is not 0, replace the cold storage plates before; if not, the number of the previous cooling stations is reduced one by one from the farthest cooling station, and the M ' is M3+ M4, the number of the new cold storage exchange plates is min { N ', M ' } and whether the new cold storage exchange plates are 0 is judged, and the replacement is abandoned until a cost-effective scheme appears or the number of the cold storage exchange plates is reduced to min { N ', M ' } to 0.
