Problems solved by technology
It is impossible to monitor the temperature of various parts in the compartment, which has the characteristics of inaccurate monitoring, especially when there are a large number of items in the compartment, there will be uneven temperature distribution in the front and back, and the monitoring results of a single temperature sensor cannot be accurate. It reflects the cooling condition in the compartment. When the refrigeration unit performs start-stop control based on the monitoring result of a single temperature sensor, it will cause frequent start-stop due to the uneven local distribution in the compartment, which will increase energy consumption and easily damage the cooling system. The unit; and it will make the local temperature in the compartment not meet the refrigeration requirements, which will easily cause deterioration and damage of items

The invention discloses a temperature whole-course monitoring control device for cold-chain logistics, and the device comprises a control module and a transport vehicle with a refrigeration compartment, and the transport vehicle is provided with a refrigeration unit. A first temperature sensor is arranged at the first air outlet, a second temperature sensor is arranged at the second air outlet, a third temperature sensor is arranged at the third air outlet, a fourth temperature sensor is arranged at the fourth air outlet, and a fifth temperature sensor is arranged at the air inlet; the system further comprises a plurality of sixth temperature sensors used for being fixed to the transportation packaging box body. The control module carries out intelligent frequency conversion control on the refrigerating unit according to temperature values collected by the first temperature sensor, the second temperature sensor, the third temperature sensor, the fourth temperature sensor, the fifth temperature sensor and the sixth temperature sensor. Multidirectional and multi-angle monitoring is carried out on the refrigerated truck carriage through the temperature sensors, intelligent frequency conversion control is carried out on the refrigerating unit, and therefore accurate refrigerating is achieved.
Description
Technical field[0001]The present invention relates to the field of logistics and transportation, and is specifically a temperature full monitoring control device for cold chain stream.Background technique[0002]With the quality requirements of food and drugs, it is especially important in the transportation process, and the safety changes are particularly important. Therefore, the refrigerator should be born. In the existing refrigerated transport vehicle, a temperature sensor is typically provided in the compartment, and the temperature in the refrigerated compartment is monitored and regulated. Instead of monitoring the temperature of the various parts of the carriage, there is an inaccurate characteristics, especially when there is a lot of items in the compartment, there is a phenomenon that the upper and rear temperature distribution unevenness, and the monitoring result of a single temperature sensor cannot be accurate. The reflection of the refrigeration in the compartment is ...
