Description

Technical Field

[0001] The utility model belongs to the field of cold chain transportation, and in particular relates to a cold chain transportation hot loading detection system. Background Art

[0002] Some foods that need to be kept fresh for a long time need to be transported through the cold chain, otherwise they will go bad. The cold chain logistics system is a low-temperature logistics system based on freezing technology and refrigeration technology, covering processes such as cold storage, cold chain transportation, cold chain distribution and cold chain sales. Many people have a wrong idea that during cold chain transportation, those refrigerated transportation equipment (transportation equipment with refrigeration devices) can freeze or heat the temperature of the goods to the required transportation temperature within a specific time during transportation. In fact, the main function of the refrigeration device loaded on the refrigerated transportation equipment is to prevent the temperature of the goods from rising. Cold chain goods generally need to be pre-cooled before loading and unloading.

[0003] Many cold storages and cold chain transport yards do not manage the pre-cooling status of goods that are about to be transported in the cold chain. The pre-cooling management method of a few cold storages and cold chain transport yards is to let the staff use a handheld temperature gun to manually measure the temperature of the goods that need to be transported in the cold chain, and then fill out a paper record sheet. There is basically no hot loading detection and alarm measures. The temperature measurement and record are done manually, which is inefficient and has a high error rate; the record sheets are all paper-based and inconvenient to query; there is a lack of hot loading detection and alarm links, and the quality of cargo transportation cannot be guaranteed. Utility Model Content

[0004] In order to improve the quality of cold chain transportation and ensure the safety of cargo transportation, the present invention provides a cold chain transportation hot loading detection system to assist in standardizing the pre-cooling link.

[0005] According to one aspect of the embodiment, a cold chain transportation hot loading detection system is provided, comprising a detection gate and a conveyor line for conveying cargo boxes through the detection gate, wherein the detection gate detects the pre-cooling temperature of the cargo loaded in the cargo box when the cargo box passes through the detection gate.

[0006] In some examples, the containers are mounted on pallets.

[0007] In some examples, an electronic tag recording information about the type of goods is attached to the pallet or the cargo box.

[0008] In some examples, the detection door is equipped with: a reader / writer for reading the electronic tag to obtain cargo type information, a thermal imager for detecting cargo temperature, and a controller connected to the reader / writer and the thermal imager.

[0009] In some examples, the controller is connected to a communication module that sends the cargo type information read by the reader and the cargo temperature data detected by the thermal imager to a server.

[0010] In some examples, after receiving the cargo temperature data sent by the controller, the server compares it with the standard temperature, and issues an alarm message if it does not meet the standard temperature.

[0011] In some examples, the server stores temperature data for the cargo.

[0012] In some examples, an alarm connected to the controller is also installed on the detection door. The controller compares the cargo temperature data with the standard temperature of pre-cooling. If the standard temperature is not met, the alarm emits an audible and / or visual alarm. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] like Figure 1 , Figure 2 As shown, a cold chain transportation hot loading detection system includes a detection gate 3 and a conveyor line 4 that conveys cargo boxes 1 through the detection gate 3. The conveyor line 4 can be a belt line or a roller conveyor line. The cargo boxes 1 are used to load cold chain goods, and different cold chain goods are generally loaded in different cargo boxes 1. The cargo boxes 1 can be placed on pallets 2. Each pallet 2 is stacked with cargo boxes 1 loaded with the same goods. Each pallet 2 has an electronic tag to distinguish different goods. The electronic tag records the type of goods. Each pallet 2 needs to pass through the detection gate 3 under the conveyor belt. As shown Figure 3 As shown, the detection door 3 is equipped with an electronic tag reader 5, a thermal imager 6 and a host 7. Figure 4As shown, the host includes a controller, a thermal imager data interface, a reader / writer interface and a communication module. The reader / writer 5 can read the information on the electronic tag. The thermal imager 6 can detect the temperature of the goods. The reader / writer 5 and the thermal imager 6 send the collected cargo type information and temperature data to the controller of the host 7, and the controller then sends the cargo type information and temperature data to the hot loading alarm system through the communication module. The hot loading alarm system is configured on the server, which is preset with a standard temperature for pre-cooling of each type of cargo. After the hot loading alarm system receives the temperature data of a type of cargo sent by the host 7, it compares it with the standard temperature for pre-cooling of the cargo. If it does not meet the standard temperature, the hot loading alarm system sends an alarm message, for example, reminding the relevant responsible person in the form of a text message. The hot loading alarm system also saves the temperature data of each type of cargo to form an electronic table for easy query. The hot loading alarm system is implemented by a simple program, and its main function is to communicate with the host 7 and make judgments, alarms and saves the detected temperature of the cargo.

[0018] The present invention can place multiple cargo boxes 1 loaded with the same goods on a pallet 2 for testing, because the same type of goods are pre-cooled in the same environment. As an alternative, it is also possible to test each cargo box 1, and then an electronic label must be attached to each cargo box.

[0019] In addition, an acoustic and / or optical alarm may be installed on the detection door 3, and the alarm is controlled by the controller of the host 7. The controller stores the standard temperature for precooling of each type of goods. The controller obtains the temperature data of a type of goods through the electronic tag reader 5 and the thermal imager 6, and compares it with the standard temperature for precooling. If it does not meet the standard temperature, the alarm will sound and / or light alarm to remind the workers on the assembly line to remove the cargo boxes that are not precooled properly.

[0020] The present invention uses automated means to complete batch temperature measurement of cold chain goods, thereby improving the efficiency of cold chain logistics. The test results are stored on the background server and can be queried at any time. It can provide hot loading alarm service to prevent cargo owners from directly loading insufficiently pre-cooled goods, thereby reducing cargo damage in the cold chain transportation link.
