The invention relates to a cold-chain logistics fresh-keeping control method which comprises the following steps: acquiring the refrigeration temperature of cold-chain articles in a transport vehicle and the area temperature of a refrigeration area in the transport vehicle, and calculating the average refrigeration temperature of the cold-chain articles and the average area temperature of the refrigeration area; segmenting the refrigeration space in the transport vehicle by using the average refrigeration temperature to obtain segmented refrigeration areas, and calculating the overlap ratio of the segmented refrigeration areas and the refrigeration areas; if the overlap ratio reaches a target threshold value, calculating the temperature difference value of the divided refrigeration area according to the average area temperature and the area temperature; taking the segmented refrigeration areas with the positive temperature difference values as first iteration areas, and taking the segmented refrigeration areas with the non-positive temperature difference values as second iteration areas; calculating a first average region temperature of the first iteration region and a second average region temperature of the second iteration region; and controlling the refrigeration temperature of the first iteration area by taking the first average area temperature as the target temperature, and controlling the refrigeration temperature of the second iteration area by taking the second average area temperature as the target temperature.
本公开涉及一种冷链物流保鲜控制方法,包括:获取运输车辆中冷链物品的冷藏温度和运输车辆中冷藏区域的区域温度,计算冷链物品的平均冷藏温度和冷藏区域的平均区域温度;用平均冷藏温度分割运输车辆内的冷藏空间得到分割冷藏区域,计算分割冷藏区域与冷藏区域的重合度;若重合度达到目标阈值,根据平均区域温度和区域温度,计算分割冷藏区域的温度差值;将温度差值为正的分割冷藏区域作为第一迭代区域,将温度差值不为正的作为第二迭代区域;计算第一迭代区域的第一平均区域温度和第二迭代区域的第二平均区域温度;以第一平均区域温度为目标温度控制第一迭代区域的制冷温度,以第二平均区域温度为目标温度控制第二迭代区域的制冷温度。
