Description

Technical Field

[0001] The present invention relates to the technical field of logistics information management, and particularly relates to a logistics vehicle management system. Background Art

[0002] Cold chain refers to a management facility that keeps products at a balanced low temperature throughout the entire production and circulation range to obtain the best quality of products. Focusing on the circulation link, the cold chain logistics chain is relatively long, with linear nodes and network nodes. The microbial, biochemical, and physical properties of products are causally related to the quality of cold chain logistics control. Among the commodities using cold chain logistics in China currently, the largest demand is for low-temperature foods and low-temperature medicines. Therefore, the requirements for cold chain logistics are more stringent.

[0003] Chinese invention patent publication No. CN115829441B discloses an intelligent cold chain logistics management method and system, including: after detecting the departure event of cold chain logistics equipment, issuing a fixed-point detection instruction to perform anomaly detection at at least one transfer station for logistics transfer; when detecting that the cold chain logistics equipment arrives at the first transfer station, detecting the change information of at least one target sub-device before and after transfer, where the target sub-device is included in the cold chain logistics equipment; among them, the detection of the change information of at least one target sub-device before and after transfer specifically includes: related actions limited within a first area to identify one-way transfer behaviors within the first area based on a second area. The beneficial effect of the present invention is that it avoids the situation of cold chain items being mixed with each other and being replaced with inferior ones during the transfer and installation process. Even if such a situation occurs, it can be accurately traced through the reported relevant information. The above intelligent cold chain logistics management method and system have the problem that due to only detecting the abnormal information of relevant goods after arriving at the transfer station and ignoring the supervision of the cold chain temperature detection data during the operation process, the temperature is unstable during transportation after leaving the transfer station and after the cold chain items are increased or decreased inside the vehicle. Summary of the Invention

[0004] The present invention aims to provide a logistics vehicle management system to overcome the problem that due to only detecting relevant abnormal information after arriving at the transfer station and ignoring the supervision of the cold chain temperature detection data during the operation process, the temperature is unstable during transportation after the cold chain items are increased or decreased inside the vehicle.

[0005] To solve the above object, the technical solution adopted by the present invention is as follows: A logistics vehicle management system includes a distribution planning module, a data processing module, a transfer collection module, a cold chain control module, and an early warning module;

[0006] The distribution planning module is used to obtain the standard change information of cold chain goods at different transfer stations;

[0007] A data processing module, which is connected to the distribution planning module and is used to output the storage area information of goods in the vehicle according to the goods standard change information. The storage area information includes the first storage area of the goods when arriving at the transfer station and the second storage area of the goods when the transfer is completed;

[0008] A transfer collection module, including an image collection unit for collecting the storage images of goods in the vehicle and a temperature collection unit for collecting the temperature of goods in the vehicle;

[0009] A cold chain control module, which is respectively connected to the data processing module and the transfer collection module, and includes a region control unit and a temperature control unit;

[0010] The region control unit is used to judge the relevant goods change information in the goods storage image according to the first storage area and the second storage area. The goods change information is used to represent one of the cold chain items entering the second storage area or the cold chain items leaving the first storage area; the change information only occurs one kind when arriving at each transfer station, otherwise the warning unit is activated;

[0011] The temperature control unit is used to output the temperature change information of the goods according to the temperature collected by the temperature collection unit, and is used to adjust the maximum transportation density of the goods according to the temperature change information;

[0012] A warning module, which is respectively connected to the region control unit and the temperature control unit, and is used to send a warning signal when more than one kind of goods change information occurs when arriving at each transfer station; and is used to send a warning signal when the temperature change information meets the first preset condition and the second preset condition; the temperature change information is used to represent that the cold chain stability after the transfer of goods does not meet the requirements when meeting the first preset condition and the second preset condition.

[0013] The principle and beneficial effects of the present invention are:

[0014] The change amount of the same batch of goods at different transfer stations is the preset standard information of the goods. The data processing module can calculate the distribution of the goods in the storage area of the vehicle according to this information, that is, the first storage area represents the goods storage area during the transfer process, and the second storage area represents the new goods storage area after the transfer station processes the goods. The goods only perform the operations of shipping or receiving goods at the transfer station. Therefore, by comparing the image information through the area control unit, the change situation of each batch of goods can be known. When the types of consecutive goods change situations are different, there is a risk that the goods are swapped or the loading and unloading are not standardized. After the transfer station finishes processing, due to the change in the total amount of goods, the temperature of the original goods in the vehicle will fluctuate. By obtaining the temperature fluctuation situation in a timely manner, the temperature fluctuation of the goods during transportation can be controlled, and the maximum cargo density of the vehicle can be adjusted according to the temperature change amount to avoid the situation where the environment where the goods are located is their normal preservation environment when the temperature tends to be stable, but the temperature fluctuation caused by the transfer process inactivates the goods.

[0015] Further, the calculation formula for the temperature change information is the average value of the sum of the temperature change differences of each good during the transfer process and before the transfer.

[0016] Further, the first preset condition is that the value of the temperature change information exceeds the first preset value and is less than the second preset value; the second preset condition is that the value of the temperature change information exceeds the second preset value.

[0017] Further, the cold chain control module further includes an abnormal monitoring unit, which is used to judge the historical temperature of each good at different transfer stations when the value of the temperature change information meets the first preset condition or the second preset condition. When the historical temperature of each good is not within the preset temperature change range, mark the good as abnormal, and the temperature control unit eliminates the temperature change value of the abnormal good and recalculates the temperature change information.

[0018] Further, the temperature acquisition unit adopts a continuous sampling mode to collect temperature at the transfer station and a discrete sampling mode to collect temperature during the transfer process.

[0019] Further, it further includes a goods statistics module, which is used to preset the temperature change range according to different types of goods.

[0020] Further, the temperature acquisition unit includes a number of infrared temperature sensors arranged at equal intervals on the inner wall of the vehicle. When the sampling mode is continuous sampling, the infrared temperature sensors with odd numbers work, and when the sampling mode is discrete sampling, the infrared temperature sensors with even numbers work. Brief Description of the Drawings

[0021] Figure 1 It is a schematic diagram of an embodiment of the present invention. Detailed Embodiment

[0022] The following is further detailed through specific embodiments:

[0023] The embodiments are basically as shown in the appended Figure 1 figures:

[0024] A logistics vehicle management system includes a distribution planning module, a data processing module, a transfer collection module, a cold chain control module, and an early warning module;

[0025] The distribution planning module is used to obtain the information on the changes in the cargo standards at different transfer stations for cold chain goods; the information on the changes in the cargo standards includes the inbound and outbound volumes and the types of goods. Specifically, 10 pieces of cargo A are received at the first transfer station, 5 pieces of cargo B are shipped out at the first transfer station, 10 pieces of cargo A are shipped out at the second transfer station, and 0 pieces of cargo B are shipped out at the second transfer station.

[0026] The data processing module is connected to the distribution planning module and is used to output the storage area information of the goods in the vehicle according to the information on the changes in the cargo standards. The storage area information includes the initial storage area of the goods, the first storage area of the goods when arriving at the transfer station, the second storage area of the goods when the transfer is completed, and the change amount of the goods in the storage area;

[0027] Specifically, the initial storage area of the goods is the storage area of the goods when loading from the starting point, and the basic information can be obtained by the image acquisition unit. The first storage area represents the storage area of the goods before inbound and outbound at the transfer station, and the second storage area represents the storage area of the goods after inbound and outbound at the transfer station. Since there may be multiple transfer stations for the goods, when the inbound and outbound at the current transfer station are completed and before arriving at the next transfer station, the second storage area is updated to the first storage area, and the new second storage area is re-divided according to the information on the changes in the cargo standards.

[0028] The transfer collection module includes an image acquisition unit for collecting the storage images of the goods in the vehicle and a temperature acquisition unit for collecting the temperature of the goods in the vehicle;

[0029] The cold chain control module is respectively connected to the data processing module and the transfer collection module, and includes a regional control unit and a temperature control unit;

[0030] The regional control unit is used to judge the relevant goods change information in the goods storage image according to the first storage area and the second storage area. The goods change information is used to represent either the cold chain items entering the second storage area or the cold chain items leaving the first storage area; the change information only occurs one kind when arriving at each transfer station, otherwise the early warning unit is activated;

[0031] The temperature control unit is used to output the temperature change information of the goods according to the temperature collected by the temperature acquisition unit, and is used to adjust the maximum transportation density of the goods according to the temperature change information; specifically, the maximum cargo density is the ratio between the volume of the transportation vehicle and the number of pieces of goods.

[0032] An early warning module is respectively connected to the regional control unit and the temperature control unit, and is used to send an early warning signal when two types of cargo change information occur when the cargo arrives at each transfer station; and is used to send an early warning signal when the temperature change information meets the first preset condition or the second preset condition; when the temperature change information meets the first preset condition and the second preset condition, it is used to indicate that the cold chain stability after the transfer of the cargo does not meet the requirements.

[0033] The change in the same batch of goods at different transfer stations is the preset standard information of the goods. The data processing module can calculate the distribution of the goods in the storage area of ​​the vehicle based on the information, that is, the first storage area represents the goods storage area during the transfer process, and the second storage area represents the new goods storage area after the transfer station processing. The goods are only shipped or received at the transfer station. Therefore, each change in the goods can be known by comparing the image information through the regional control unit. When the types of continuous changes in goods are different, such as shipping and receiving the same kind of goods at the same time, there is a risk of goods being replaced or loading and unloading being irregular. After the transfer station processing is completed, the change in the total amount of goods will cause the temperature fluctuation of the original goods in the vehicle. By timely obtaining the temperature fluctuation, it is ensured that the temperature fluctuation of the goods during the transportation process is controllable, and the maximum cargo density of the vehicle is adjusted according to the temperature change to avoid the situation where the environment where the goods are located is their normal storage environment when the temperature tends to be stable, but the temperature fluctuation caused by the transfer process causes the goods to be inactivated.

[0034] The calculation formula for temperature change information is the average value of the sum of the temperature change differences between each cargo during transit and before transit.

[0035] The first preset condition is that the temperature change information value exceeds the first preset value and is less than the second preset value; the second preset condition is that the temperature change information value exceeds the second preset value. The first preset value is less than the second preset value, and the temperature change information is an absolute value.

[0036] Among them, the first preset value represents that the temperature change range of the goods is within the remediable range, that is, the goods can be cooled by increasing the operating power of the refrigeration equipment in the cold chain transportation equipment. The second preset value represents that the temperature of the goods has exceeded the maximum recommended storage temperature.

[0037] The cold chain control module also includes an abnormality monitoring unit, which is used to determine the historical temperature of each cargo at different transfer stations when the temperature change information value meets the first preset condition or the second preset condition. When the historical temperature of each cargo is not within the preset temperature change range, the cargo is marked as abnormal, and the temperature control unit eliminates the temperature change value of the abnormal cargo and recalculates the temperature change information.

[0038] Since the historical temperature has always been abnormal, the temperature of the goods was abnormal before entering the cold chain. Therefore, the temperature change of the goods was not caused by the temperature change during the transfer process. When the goods arrive at the transfer station and the goods standard change information of the transfer station shows the information corresponding to the goods, the staff will unload the goods marked as abnormal.

[0039] The goods statistics module is used to preset the temperature change range according to different types of goods. Different temperature change ranges for different goods inactivation are preset, and the temperature change ranges are matched to the abnormal monitoring unit for abnormal judgment based on the historical temperature of the goods.

[0040] The temperature acquisition unit collects temperature in a continuous sampling mode at the transfer station and in a discrete sampling mode during the transfer process. Among them, the continuous sampling mode is uninterrupted sampling, and the discrete sampling mode is sampling every 5 minutes. The temperature acquisition unit includes a number of infrared temperature sensors evenly arranged on the inner wall of the vehicle. When the sampling mode is continuous sampling, the infrared temperature sensors with odd numbers work. When the sampling mode is discrete sampling, the infrared temperature sensors with even numbers work. The accuracy of temperature acquisition is ensured by continuously monitoring the temperature during the transfer process.

[0041] The above are only the embodiments of the present invention. Common knowledge such as the specific structure and characteristics known in the solution is not described in detail here. It should be noted that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can still be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent.
