Description

Technical Field

[0001] The present invention relates to the technical field of cold storage abnormal detection, and more specifically, to a cold storage operation abnormal detection system based on big data technology. Background Art

[0002] A cold storage refers to a device that uses artificial means to create an environment with a temperature or humidity different from that outdoors, and is also a constant temperature and humidity storage device for items such as food, liquids, chemicals, medicines, vaccines, and scientific experiments. During the process of storing objects inside, the temperature inside the cold storage will change. Fluctuations in the internal temperature of the cold storage are normal, but when the temperature changes significantly, it will affect the items stored in the cold storage. For example, if the temperature of the meat stored in the cold storage drops, it is likely to melt, resulting in the unusability of the frozen meat. At the same time, when the cold storage door is opened, the cold air inside the cold storage will leak. If the items near the door are not quickly frozen, they are likely to melt. Also, when the side wall of the cold storage is damaged, it will affect the refrigeration inside the cold storage, thereby affecting the preservation effect of the items in the cold storage. In addition, the environment in the cold storage is harsh. When a living thing accidentally enters the cold storage, it is likely to malfunction due to hypothermia. Therefore, it is necessary to detect the cold storage to avoid abnormal situations in the cold storage. Summary of the Invention

[0003] The purpose of the present invention is to provide a cold storage operation abnormal detection system based on big data technology to solve the problems raised in the above background art.

[0004] To achieve the above purpose, a cold storage operation abnormal detection system based on big data technology is provided, including a regulation unit, a cold storage status monitoring unit, and a temperature detection unit;

[0005] The regulation unit selects the temperature of the cold air inside the cold storage through a touch display screen. After the temperature is selected, the regulation unit transmits the selected temperature data to the cold storage status monitoring unit;

[0006] The cold storage status monitoring unit uses a camera to detect the opening and closing of the cold storage door, and transmits the detected opening and closing situations to the temperature detection unit. At the same time, the cold storage status monitoring unit determines dynamic objects through the images captured by the camera. When a dynamic object is determined to exist, it determines the opening and closing, and feeds back the results to the regulation unit, and the regulation unit gives a warning;

[0007] The temperature detection unit receives the temperature information transmitted by the regulation unit to control the refrigeration of the cold storage, and uses n temperature sensors to detect the temperature at various positions in the cold storage during the refrigeration control process. During the detection process, it judges the acquired temperature information to determine whether there is a temperature loss in the cold storage. At the same time, when the temperature detection unit detects a temperature loss, it feeds back to the cold storage status monitoring unit, so that the cold storage status monitoring unit transmits the opening and closing conditions of the cold storage door to the temperature detection unit, and the temperature detection unit judges the reason for the temperature loss in the cold storage. At the same time, when the cold storage status monitoring unit detects that the cold storage door is opened, the cold storage status monitoring unit feeds back to the temperature detection unit, so that the temperature detection unit controls the refrigerators in the cold storage to perform corresponding refrigeration control on different positions in the cold storage.

[0008] As a further improvement of this technical solution, the regulation unit includes a temperature regulation module. The temperature regulation module collects the control temperature data of the temperature input in the touch display screen, and transmits the temperature data to the temperature detection unit, and the temperature detection unit controls the refrigerator to perform refrigeration.

[0009] As a further improvement of this technical solution, the temperature detection unit includes a temperature detection module and a refrigeration control module;

[0010] The temperature detection module is used to control n temperature sensors in the cold storage to detect the temperature at various places in the cold storage and obtain the temperature data at various places in the cold storage;

[0011] The refrigeration control module receives the temperature data transmitted by the temperature regulation module, and controls the temperature of n refrigerators according to the received temperature data. At the same time, during the process of the refrigeration control module controlling the refrigerator to perform refrigeration, the refrigeration control module transmits the control result to the temperature detection module, so that the door opening and closing detection module controls the temperature sensors at the positions corresponding to the refrigerators to detect the temperature according to the positions of the refrigerators controlled by the refrigeration control module in the cold storage;

[0012] The refrigeration control module marks the positions of n refrigerators in the cold storage, and the temperature detection module marks the positions of the temperature sensors in the corresponding areas according to the positions of the refrigerators marked by the refrigeration control module.

[0013] As a further improvement of this technical solution, the temperature detection unit further includes a temperature loss abnormal judgment module;

[0014] The hypothermia anomaly judgment module receives the temperature data detected by the temperature detection module for the internal temperature of the cold storage, compares the received temperature data with the regulated temperature data received in the temperature regulation module to determine the temperature difference, and transmits the temperature difference data to the regulation unit. At the same time, the hypothermia anomaly judgment module transmits the temperature difference data to the refrigeration control module, and the refrigeration control module controls the refrigerator at the corresponding position of the cold storage according to the situation of the temperature difference data.

[0015] As a further improvement of this technical solution, the cold storage status monitoring unit includes a door opening / closing detection module. The door opening / closing detection module uses a camera to take pictures of the cold storage door and judges the opening and closing status of the cold storage door through the images taken by the camera.

[0016] When the hypothermia anomaly judgment module calculates the temperature difference data, it judges the magnitude of the temperature difference data. At the same time, an anomaly threshold is set in the hypothermia anomaly judgment module. When the temperature difference data is greater than the anomaly threshold, the hypothermia anomaly judgment module feeds back to the door opening / closing detection module, so that the door opening / closing detection module sends the opening and closing status of the cold storage door to the hypothermia anomaly judgment module, and the hypothermia anomaly judgment module judges whether the cold storage is in a hypothermia situation according to the opening and closing status of the cold storage door.

[0017] As a further improvement of this technical solution, the cold storage status monitoring unit further includes a dynamic object capture module. The dynamic object capture module uses a camera to take pictures of the inside of the cold storage, captures dynamic objects during the process of the camera taking pictures of the inside of the cold storage, and at the same time, when the dynamic object capture module captures a dynamic object, it feeds back to the door opening / closing detection module, so that the door opening / closing detection module sends the opening and closing status of the cold storage door to the dynamic object capture module.

[0018] As a further improvement of this technical solution, the regulation unit further includes a warning judgment module. The warning judgment module receives the data transmitted from the dynamic object capture module and the hypothermia anomaly judgment module and performs corresponding warning operations according to the received data.

[0019] When the warning judgment module receives the hypothermia anomaly situation judged by the hypothermia anomaly judgment module, it performs warning display through the touch display screen.

[0020] When the dynamic object capture module captures a dynamic object and the information transmitted by the door opening / closing detection module indicates that the cold storage door is in the closed state, the dynamic object capture module feeds back to the warning judgment module, and the warning judgment module performs corresponding warning operations.

[0021] As a further improvement of this technical solution, the hypothermia anomaly judgment module has the following situations when judging whether hypothermia occurs:

[0022] ①. The hypothermia abnormality judgment module calculates the difference data of the temperature, but the calculated difference data of the temperature does not exceed the abnormality threshold. In this case, no hypothermia abnormality situation is issued. At this time, the hypothermia abnormality judgment module feeds back to the refrigeration control module, so that the refrigeration control module performs refrigeration control on the cooler at the position corresponding to the temperature sensor corresponding to the calculated difference data of the temperature;

[0023] ②. The hypothermia abnormality judgment module calculates the difference data of the temperature, and the calculated difference data of the temperature exceeds the abnormality threshold. However, when the hypothermia abnormality judgment module feeds back to the door opening and closing detection module, the information transmitted by the door opening and closing detection module to the hypothermia abnormality judgment module is that the cold storage door is open. At this time, the hypothermia abnormality judgment module does not issue a hypothermia abnormality situation, but the hypothermia abnormality judgment module feeds back the signal that the cold storage door is open to the warning judgment module;

[0024] ③. The hypothermia abnormality judgment module calculates the difference data of the temperature, and the calculated difference data of the temperature exceeds the abnormality threshold. When the hypothermia abnormality judgment module feeds back to the door opening and closing detection module, the information transmitted by the door opening and closing detection module to the hypothermia abnormality judgment module is that the cold storage door is closed. At this time, the hypothermia abnormality judgment module issues a hypothermia abnormality signal. After receiving the hypothermia abnormality signal, the warning judgment module gives a warning. At the same time, the hypothermia abnormality judgment module transmits information to the refrigeration control module, so that the refrigeration control module performs refrigeration control on the cooler at the position corresponding to the temperature sensor corresponding to the calculated difference data of the temperature;

[0025] ④. The hypothermia abnormality judgment module calculates the difference data of the temperature. When the information transmitted by the door opening and closing detection module to the hypothermia abnormality judgment module is that the cold storage door is open, and the temperature data collected by the temperature detection module in the cold storage gradually decreases from near the door to far from the door, this indicates that the cold storage is in normal hypothermia. At this time, the hypothermia abnormality judgment module does not issue a hypothermia abnormality situation, but the hypothermia abnormality judgment module feeds back the signal that the cold storage door is open to the warning judgment module;

[0026] When the information transmitted by the door opening and closing detection module to the hypothermia abnormality judgment module is that the cold storage door is closed, and the temperature data collected by the temperature detection module in the cold storage from near the door to far from the door is chaotic, this indicates that the cold storage is in a hypothermia state. At this time, the hypothermia abnormality judgment module issues a hypothermia abnormality signal. After receiving the hypothermia abnormality signal, the warning judgment module gives a warning.

[0027] Compared with the prior art, the beneficial effects of the present invention:

[0028] 1. In the cold storage operation anomaly detection system based on big data technology, the temperature detection module is used to detect the temperature at various positions in the cold storage, and the temperature difference data inside the cold storage is calculated by the abnormal temperature loss judgment module to calculate whether there is a temperature loss in the cold storage. At the same time, when the abnormal temperature loss judgment module determines that the temperature difference data exceeds the abnormal threshold, it feeds back to the door opening and closing detection module, so that the door opening and closing detection module transmits the opening and closing situation of the cold storage door to the abnormal temperature loss judgment module, enabling the abnormal temperature loss judgment module to determine the reason for the temperature loss. And when the cold storage door is closed, it feeds back to the warning judgment module, causing the warning judgment module to issue a warning, so that the operator can promptly repair the cold storage to ensure the normal freezing of the items in the cold storage.

[0029] 2. In the cold storage operation anomaly detection system based on big data technology, when the abnormal temperature loss judgment module calculates the temperature difference data, it feeds back to the refrigeration control module, enabling the refrigeration control module to control the cooler near the sensor with the temperature difference data, so that the cooler cools the position in the cold storage with the temperature difference data, accelerating the speed of cooling the cold storage to the specified temperature and ensuring the normal storage of the objects in the cold storage.

[0030] 3. In the cold storage operation anomaly detection system based on big data technology, the dynamic object capture module captures the dynamic objects that appear in the cold storage, and when a dynamic object is captured, it feeds back to the door opening and closing detection module, so that the door opening and closing detection module transmits the opening and closing situation of the cold storage door to the dynamic object capture module. When a dynamic object is captured while the cold storage door is closed, the dynamic object capture module feeds back to the warning judgment module, causing the warning judgment module to issue a warning to avoid the risk of life of dynamic organisms due to low temperature in the cold storage and improve the safety of the cold storage during use.

Embodiment

[0040] In order to ensure that the cold storage can effectively freeze and store the objects inside it, the present invention provides a cold storage operation anomaly detection system based on big data technology to improve the storage effect of the cold storage on objects. When the cold storage has an operation anomaly, it can be detected in time to avoid problems caused by too slow discovery time in the cold storage. Please refer to the following Figures 1 - 3 As shown, the purpose of this embodiment is to include a regulation unit 1, a cold storage state monitoring unit 2, and a temperature detection unit 3;

[0041] The regulation unit 1 selects the temperature of the cold air inside the cold storage through the touch display screen, and after the temperature is selected, the regulation unit 1 transmits the selected temperature data to the cold storage state monitoring unit 2;

[0042] The regulation unit 1 includes a temperature regulation module 11. The temperature regulation module 11 collects the control temperature data of the temperature input in the touch display screen, transmits the temperature data to the temperature detection unit 3, and the temperature detection unit 3 controls the refrigerator to refrigerate. By receiving the refrigeration temperature set by the user through the temperature regulation module 11, the whole system has data for refrigerating the cold storage, so that the temperature detection unit 3 can control the refrigerator to cool the temperature in the cold storage to the specified temperature, ensuring that the objects placed in the cold storage can be effectively frozen.

[0043] The cold storage status monitoring unit 2 uses a camera to detect the opening and closing of the cold storage door, and transmits the detected opening and closing conditions to the temperature detection unit 3. At the same time, the cold storage status monitoring unit 2 determines dynamic objects through the images captured by the camera. When a dynamic object is determined to exist, it determines the opening and closing, and feeds back the results to the control unit 1, and the control unit 1 gives a warning;

[0044] The cold storage status monitoring unit 2 includes a door opening and closing detection module 21. The door opening and closing detection module 21 uses a camera to take pictures of the cold storage door, and judges the opening and closing conditions of the cold storage door through the images taken by the camera;

[0045] The cold storage status monitoring unit 2 also includes a dynamic object capture module 22. The dynamic object capture module 22 takes pictures of the inside of the cold storage through the camera, and captures dynamic objects during the process of the camera taking pictures of the inside of the cold storage. At the same time, when the dynamic object capture module 22 captures a dynamic object, it feeds back to the door opening and closing detection module 21, so that the door opening and closing detection module 21 sends the opening and closing conditions of the cold storage door to the dynamic object capture module 22. By sending the opening and closing conditions of the cold storage door obtained by the door opening and closing detection module 21 to the dynamic object capture module 22, the dynamic object capture module 22 learns the reason for the appearance of dynamic objects in the cold storage. For example, when the dynamic object capture module 22 obtains a dynamic object in the cold storage, at this time the cold storage door is in the open state, which means that a staff member has entered the cold storage, and the staff member places an object in the cold storage or takes an item from the cold storage, etc. This is a normal working state. However, when the cold storage door is in the closed state, but the dynamic object capture module 22 captures a dynamic object in the cold storage, this indicates that a dynamic object has been locked in the cold storage. Because the temperature of the cold storage is low, it is easy to freeze the dynamic object. At this time, the dynamic object capture module 22 transmits this situation to the control unit 1, so that the control unit 1 obtains the data transmitted from the dynamic object capture module 22.

[0046] The temperature detection unit 3 receives the temperature information transmitted by the regulation unit 1 to control the refrigeration of the cold storage. During the refrigeration control process, n temperature sensors are used to detect the temperature at various positions in the cold storage. During the detection process, the acquired temperature information is judged to determine whether there is a temperature loss in the cold storage. At the same time, when the temperature detection unit 3 detects a temperature loss, the temperature detection unit 3 feeds back to the cold storage status monitoring unit 2, so that the cold storage status monitoring unit 2 transmits the opening and closing conditions of the cold storage door to the temperature detection unit 3. The temperature detection unit 3 judges the reason for the temperature loss in the cold storage. At the same time, when the cold storage status monitoring unit 2 detects that the cold storage door is opened, the cold storage status monitoring unit 2 feeds back to the temperature detection unit 3, so that the temperature detection unit 3 controls the refrigerators in the cold storage to perform corresponding refrigeration control on different positions in the cold storage.

[0047] The temperature detection unit 3 includes a temperature detection module 31 and a refrigeration control module 33;

[0048] The temperature detection module 31 is used to control n temperature sensors in the cold storage to detect the temperature at various places in the cold storage and obtain the temperature data at various places in the cold storage; by setting multiple temperature sensors to detect various positions in the cold storage to obtain the temperature at various positions in the cold storage. At the same time, the n temperature sensors are all installed on the side wall of the cold storage and are arranged in a dot-shaped uniform array during installation. Through the dot-shaped array arrangement, the n temperature sensors can obtain the temperature change conditions at various positions in the cold storage;

[0049] The refrigeration control module 33 receives the temperature data transmitted by the temperature regulation module 11 and controls the temperature of the n refrigerators according to the received temperature data. At the same time, during the process of the refrigeration control module 33 controlling the refrigerators to refrigerate, the refrigeration control module 33 transmits the control result to the temperature detection module 31, so that the door opening and closing detection module 21 controls the temperature sensors at the positions corresponding to the refrigerators according to the positions of the refrigerators controlled by the refrigeration control module 33 in the cold storage to detect the temperature, so that the temperature detection module 31 detects the temperature change conditions near the refrigerators;

[0050] The refrigeration control module 33 marks the positions of the n refrigerators in the cold storage, and the temperature detection module 31 marks the positions of the temperature sensors in the corresponding areas according to the positions of the refrigerators marked by the refrigeration control module 33.

[0051] Reference Figure 3 As shown, the n temperature sensors are evenly arranged on the side wall of the cold storage, while the n refrigerators are arranged along the side wall track at the bottom of the cold storage. The temperature sensors at the positions corresponding to the refrigerators detect the corresponding positions of the cold storage. For example, Figure 3 the temperature sensor in the range of A corresponding to the refrigerator at a in

[0052] The temperature detection unit 3 further includes a hypothermia abnormality judgment module 32;

[0053] The hypothermia abnormality judgment module 32 receives the temperature data detected by the temperature detection module 31 for the internal temperature of the cold storage, compares the received temperature data with the regulated temperature data received in the temperature regulation module 11 to determine the temperature difference, and transmits the temperature difference data to the regulation unit 1. At the same time, the hypothermia abnormality judgment module 32 transmits the temperature difference data to the refrigeration control module 33. The refrigeration control module 33 performs refrigeration control on the refrigerators at corresponding positions in the cold storage according to the situation of the temperature difference data. By controlling the refrigerators corresponding to the positions where the temperature difference data appears through the refrigeration control module 33, the speed of temperature regulation in the cold storage can be accelerated, so that the internal temperature of the cold storage can quickly return to the specified temperature, ensuring the safe storage of the objects in the cold storage.

[0054] When the hypothermia abnormality judgment module 32 calculates the temperature difference data, it judges the magnitude of the temperature difference data. When judging the temperature difference data, it subtracts the temperature collected by the temperature sensor from the specified temperature data in the temperature regulation module 11. At the same time, an abnormal threshold is set in the hypothermia abnormality judgment module 32. When the temperature difference data is greater than the abnormal threshold, the hypothermia abnormality judgment module 32 feeds back to the door opening and closing detection module 21, so that the door opening and closing detection module 21 sends the opening and closing conditions of the cold storage door to the hypothermia abnormality judgment module 32, and the hypothermia abnormality judgment module 32 judges whether the cold storage is in a hypothermia situation according to the opening and closing conditions of the cold storage door.

[0055] The regulation unit 1 further includes a warning judgment module 12. The warning judgment module 12 receives the data transmitted from the dynamic object capture module 22 and the hypothermia abnormality judgment module 32, and performs corresponding warning operations according to the received data;

[0056] The hypothermia abnormality judgment module 32 has the following situations when judging whether hypothermia occurs:

[0057] ①. The hypothermia abnormality judgment module 32 calculates the temperature difference data, but the calculated temperature difference data does not exceed the abnormal threshold. At this time, no hypothermia abnormality situation is issued. At this time, the hypothermia abnormality judgment module 32 feeds back to the refrigeration control module 33, so that the refrigeration control module 33 performs refrigeration control on the refrigerator corresponding to the position of the temperature sensor corresponding to the calculated temperature difference data, so that the area with temperature difference in the cold storage returns to the specified temperature;

[0058] ②. The hypothermia anomaly judgment module 32 calculates the temperature difference data. The calculated temperature difference data exceeds the anomaly threshold. However, when the hypothermia anomaly judgment module 32 feeds back to the door opening / closing detection module 21, the information transmitted by the door opening / closing detection module 21 to the hypothermia anomaly judgment module 32 is that the cold storage door is open. At this time, the hypothermia anomaly judgment module 32 does not issue a hypothermia anomaly situation, but the hypothermia anomaly judgment module 32 feeds back a signal that the cold storage door is open to the warning judgment module 12;

[0059] ③. The hypothermia anomaly judgment module 32 calculates the temperature difference data. The calculated temperature difference data exceeds the anomaly threshold. When the hypothermia anomaly judgment module 32 feeds back to the door opening / closing detection module 21, the information transmitted by the door opening / closing detection module 21 to the hypothermia anomaly judgment module 32 is that the cold storage door is closed. At this time, the hypothermia anomaly judgment module 32 issues a hypothermia anomaly signal. After receiving the hypothermia anomaly signal, the warning judgment module 12 gives a warning. At the same time, the hypothermia anomaly judgment module 32 transmits information to the refrigeration control module 33, so that the refrigeration control module 33 performs refrigeration control on the cooler at the position corresponding to the temperature sensor corresponding to the calculated temperature difference data, so that the area with temperature difference in the cold storage returns to the specified temperature;

[0060] ④. The hypothermia anomaly judgment module 32 calculates the temperature difference data. When the information transmitted by the door opening / closing detection module 21 to the hypothermia anomaly judgment module 32 is that the cold storage door is open, and the temperature data collected by the temperature detection module 31 in the cold storage gradually decreases from near the door to far from the door. At this time, it indicates that the cold storage has normal hypothermia. Because when the cold storage door is open, the cold air in the cold storage will flow out from the door, causing the cold air near the door to be lost. However, the cold air inside the cold storage is not lost. During the opening of the door, the cold air will fall due to gravity, causing the temperature near the door to rise, and the temperature far from the door does not rise. Moreover, the closer the position is to the door in the cold storage, the more the temperature rises. However, the temperature rise caused by the opening of the door is a normal situation. At this time, the hypothermia anomaly judgment module 32 does not issue a hypothermia anomaly situation, but the hypothermia anomaly judgment module 32 feeds back a signal that the cold storage door is open to the warning judgment module 12;

[0061] When the information transmitted by the door opening / closing detection module 21 to the abnormal temperature loss judgment module 32 indicates that the cold storage door is closed, but the temperature data collected by the temperature detection module 31 in the cold storage is chaotic from the temperature data near the door to the temperature data away from the door. That is, at this time, the temperature in the cold storage is not higher near the door, but the temperature at a certain place inside the cold storage is higher than that at other positions. This indicates that there is a problem with the refrigeration situation at this place. It may be that the refrigerator is damaged, or there is a problem with the side wall of the cold storage. At this time, it shows that the cold storage is in a state of abnormal temperature loss. At this time, the abnormal temperature loss judgment module 32 sends out a signal of abnormal temperature loss. After receiving the signal of abnormal temperature loss, the warning judgment module 12 gives a warning, and the user conducts on-site diagnosis to ensure that the cold storage can store items normally.

[0062] When the warning judgment module 12 receives the situation of abnormal temperature loss judged by the abnormal temperature loss judgment module 32, it gives a warning display through the touch display screen;

[0063] When the dynamic object capture module 22 captures a dynamic object and the information transmitted by the door opening / closing detection module 21 indicates that the cold storage door is in the closed state, the dynamic object capture module 22 feeds back to the warning judgment module 12, and the warning judgment module 12 performs corresponding warning operations.

[0064] Summary of the usage process:

[0065] Set the temperature of the cold storage through the temperature control module 11. The temperature control module 11 transmits the set temperature to the temperature detection module 31 and the refrigeration control module 33. The temperature detection module 31 controls the temperature sensor to detect the temperature inside the cold storage, and the detection result is transmitted to the abnormal temperature loss judgment module 32. The abnormal temperature loss judgment module 32 calculates the temperature difference data and transmits the temperature difference data to the refrigeration control module 33. The refrigeration control module 33 controls the refrigerator at the corresponding position of the sensor with the temperature difference data to make the refrigerator refrigerate to adjust the temperature at this position. Especially when new items are put into the cold storage and the temperature in the cold storage changes greatly, at this time, it is necessary to accurately control the refrigerator to refrigerate through the refrigeration control module 33 to accelerate the temperature in the cold storage to return to the specified value.

[0066] When the hypothermia abnormality judgment module 32 calculates that the difference data of the temperature is greater than the abnormal threshold, the hypothermia abnormality judgment module 32 sends a signal to the door opening and closing detection module 21, causing the door opening and closing detection module 21 to send the situation of the cold storage door opening and closing to the hypothermia abnormality judgment module 32. If the information received by the hypothermia abnormality judgment module 32 indicates that the cold storage door is in the open state, the hypothermia abnormality judgment module 32 can just feedback the situation of the cold storage door opening to the warning judgment module 12. When the information received by the hypothermia abnormality judgment module 32 indicates that the cold storage door is in the closed state, this indicates that there is a fault in the cold storage, such as a damaged refrigerator or a damaged outer wall of the cold storage, etc. At this time, the hypothermia abnormality judgment module 32 feeds back to the warning judgment module 12, causing the warning judgment module 12 to give a warning.

[0067] During the use of the cold storage, the dynamic object capture module 22 captures the dynamic objects in the cold storage. When the dynamic object capture module 22 captures a dynamic object, the dynamic object capture module 22 feeds back to the door opening and closing detection module 21, causing the door opening and closing detection module 21 to send the situation of the cold storage door opening and closing to the dynamic object capture module 22. When the cold storage door is in the open state, the dynamic object capture module 22 ignores this information. When the cold storage door is in the closed state, the dynamic object capture module 22 transmits this type of information to the warning judgment module 12, and the warning judgment module 12 gives a warning. The types of warnings can be light warnings, sound warnings, etc., to prevent organisms from suffering from hypothermia in the cold storage.
