Description

Technical Field

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

[0002] Cold storage refers to the use of artificial means to create an environment with different temperature or humidity from the outdoor environment. It is also a constant temperature and humidity storage equipment for food, liquids, chemicals, medicines, vaccines, scientific experiments and other items. In the process of storing objects inside the cold storage, the temperature inside the cold storage will change. The fluctuation of the temperature inside the cold storage is normal, but when the temperature changes drastically, it will affect the items stored in the cold storage. For example, if the meat stored in the cold storage encounters a loss of temperature, it is easy to melt, and the frozen meat cannot be used. At the same time, when the door of the cold storage is opened, the cold air in the cold storage will leak, but if the items near the door are not frozen quickly, they are easy to melt. At the same time, when the side wall of the cold storage is damaged, it will also affect the refrigeration inside the cold storage, and then affect the preservation effect of the cold storage on the items. At the same time, the environment in the cold storage is bad. When living things enter the cold storage without paying attention, it is easy to malfunction due to loss of temperature. Therefore, it is necessary to detect the cold storage to avoid abnormal conditions in the cold storage. Summary of the invention

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

[0004] To achieve the above purpose, a cold storage operation abnormality detection system based on big data technology is provided, including a control unit, a cold storage status monitoring unit and a temperature detection unit; The control unit selects the temperature of the cold air inside the cold storage through the touch screen, and after the temperature is selected, the control unit transmits the selected temperature data to the cold storage status monitoring unit; The cold storage state monitoring unit uses a camera to detect the opening and closing of the door of the cold storage, and transmits the detected opening and closing conditions to the temperature detection unit. At the same time, the cold storage state monitoring unit determines the dynamic object through the image captured by the camera, and when it is determined that there is a dynamic object, it determines the opening and closing of the door, and feeds back the result to the control unit, which issues a warning; The temperature detection unit receives the temperature information transmitted by the control unit to control the refrigeration of the cold storage, and uses n temperature sensors to detect the temperature of each position of the cold storage during the refrigeration control process. During the detection process, the acquired temperature information is judged to determine whether the cold storage is hypothermic. At the same time, when the temperature detection unit detects hypothermia, the temperature detection unit feeds back to the cold storage status monitoring unit, so that the cold storage status monitoring unit transmits the opening and closing of the cold storage door to the temperature detection unit, and the temperature detection unit judges the cause of the hypothermia of the cold storage. At the same time, when the cold storage status monitoring unit detects that the cold storage door is open, the cold storage status monitoring unit feeds back to the temperature detection unit, so that the temperature detection unit controls the refrigerator in the cold storage to perform corresponding refrigeration control on different positions in the cold storage.

[0005] As a further improvement of the present technical solution, the control unit includes a temperature control module, which collects control temperature data of the temperature input in the touch display screen, transmits the temperature data to the temperature detection unit, and the temperature detection unit controls the refrigerator to perform cooling.

[0006] As a further improvement of the technical solution, the temperature detection unit includes a temperature detection module and a refrigeration control module; The temperature detection module is used to control n temperature sensors in the cold storage to detect the temperature of various places in the cold storage, and obtain temperature data of various places in the cold storage; The refrigeration control module receives the temperature data transmitted by the temperature control module, and controls the temperature of the n refrigerators according to the received temperature data. At the same time, when the refrigeration control module controls the refrigerator to refrigerate, 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 sensor at the corresponding position of the refrigerator to detect the temperature according to the position of the refrigerator controlled by the refrigeration control module in the cold storage; The refrigeration control module marks the positions of n refrigerators in the cold storage, and the temperature detection module marks the positions of temperature sensors in corresponding areas according to the positions of the refrigerators marked by the refrigeration control module.

[0007] As a further improvement of the technical solution, the temperature detection unit also includes a temperature loss abnormality judgment module; The temperature loss abnormality judgment module receives the temperature data of the internal temperature of the cold storage detected by the temperature detection module, and compares the received temperature data with the regulated temperature data received in the temperature control module, determines the temperature difference, and transmits the temperature difference data to the control unit. At the same time, the temperature loss abnormality judgment module transmits the temperature difference data to the refrigeration control module, and the refrigeration control module performs refrigeration control on the refrigerator at the corresponding position of the cold storage according to the temperature difference data.

[0008] As a further improvement of the technical solution, the cold storage state monitoring unit includes a door opening and closing detection module, which uses a camera to shoot the door of the cold storage, and determines the opening and closing status of the cold storage door through the image taken by the camera; When calculating the temperature difference data, the temperature abnormality judgment module judges the size of the temperature difference data, and sets an abnormal threshold in the temperature abnormality judgment module. When the temperature difference data is greater than the abnormal threshold, the temperature abnormality judgment module feeds back to the door opening and closing detection module, so that the door opening and closing detection module sends the opening and closing status of the cold storage door to the temperature abnormality judgment module, and the temperature abnormality judgment module judges whether the cold storage is in a temperature loss condition according to the opening and closing status of the cold storage door.

[0009] As a further improvement of the present technical solution, the cold storage status monitoring unit also includes a dynamic object capture module, which uses a camera to shoot the situation inside the cold storage, and captures dynamic objects during the process of the camera shooting the situation inside the cold storage. At the same time, when the dynamic object capture module captures the dynamic object, it provides feedback to the door opening and closing detection module, so that the door opening and closing detection module sends the opening and closing status of the cold storage door to the dynamic object capture module.

[0010] As a further improvement of the technical solution, the control unit further includes a warning judgment module, which receives data transmitted from the dynamic object capture module and the hypothermia abnormality judgment module, and performs corresponding warning operations according to the received data; When the warning judgment module receives the abnormal hypothermia situation judged by the abnormal hypothermia judgment module, the warning display is displayed through the touch screen; When the dynamic object capture module captures a dynamic object, and the information transmitted by the door opening and closing detection module is that the cold storage door is in a closed state, the dynamic object capture module feeds back to the warning judgment module, and the warning judgment module performs a corresponding warning operation.

[0011] As a further improvement of the technical solution, the hypothermia abnormality judgment module has the following conditions when judging whether hypothermia occurs: ①, the temperature loss abnormality judgment module calculates the temperature difference data, but the calculated temperature difference data does not exceed the abnormal threshold, and no temperature loss abnormality is issued at this time. At this time, the temperature loss abnormality judgment module feeds back to the refrigeration control module, so that the refrigeration control module performs refrigeration control on the refrigerator at the position corresponding to the temperature sensor corresponding to the calculated temperature difference data; ②, the temperature abnormality judgment module calculates the temperature difference data, and the calculated temperature difference data exceeds the abnormal threshold. However, when the temperature abnormality judgment module feeds back to the door opening and closing detection module, the information transmitted to the temperature abnormality judgment module by the door opening and closing detection module is that the cold storage door is open. At this time, the temperature abnormality judgment module does not issue a temperature abnormality, but the temperature abnormality judgment module feeds back a signal that the cold storage door is open to the warning judgment module; ③. The temperature abnormality judgment module calculates the temperature difference data. The calculated temperature difference data exceeds the abnormal threshold. When the temperature abnormality judgment module feeds back to the door opening and closing detection module, the information transmitted to the temperature abnormality judgment module by the door opening and closing detection module is that the cold storage door is closed. At this time, the temperature abnormality judgment module sends a temperature abnormality signal. After receiving the temperature abnormality signal, the warning judgment module issues a warning. At the same time, the temperature abnormality judgment module transmits information to the refrigeration control module, so that the refrigeration control module performs refrigeration control on the refrigerator at the position corresponding to the temperature sensor corresponding to the calculated temperature difference data; ④. The temperature abnormality judgment module calculates the temperature difference data. When the information transmitted to the temperature abnormality judgment module by the door opening and closing detection module is that the cold storage door is open, and the temperature data in the cold storage collected by the temperature detection module gradually decreases from close to the door to far away from the door, it indicates that the cold storage is in normal temperature loss. At this time, the temperature abnormality judgment module does not issue a temperature abnormality, but the temperature abnormality judgment module feeds back a signal that the cold storage door is open to the warning judgment module; When the information transmitted to the temperature abnormality judgment module by the door opening and closing detection module is that the cold storage door is closed, and the temperature data in the cold storage collected by the temperature detection module is chaotic from the temperature data close to the door to the temperature data far from the door, it indicates that the cold storage is in a temperature-loss state. At this time, the temperature abnormality judgment module sends a temperature abnormality signal, and the warning judgment module issues a warning after receiving the temperature abnormality signal.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. In the cold storage operation abnormality detection system based on big data technology, the temperature of each position in the cold storage is detected by the temperature detection module, and the temperature difference data of the inside of the cold storage is calculated by the temperature loss abnormality judgment module to calculate whether the temperature in the cold storage is losing temperature. At the same time, when the temperature loss abnormality judgment module determines that the temperature difference data exceeds the abnormal threshold, it will feedback to the door opening and closing detection module, so that the door opening and closing detection module transmits the opening and closing status of the cold storage door to the temperature loss abnormality judgment module, so that the temperature loss abnormality judgment module determines the cause of the temperature loss, and when the cold storage door is closed, it will feedback to the warning judgment module, so that the warning judgment module will issue a warning, so that the operator can inspect the cold storage in time to ensure the normal freezing of the items in the cold storage.

[0013] 2. In the cold storage operation abnormality detection system based on big data technology, when the temperature difference data is calculated by the temperature loss abnormality judgment module, feedback is given to the refrigeration control module, so that the refrigeration control module controls the refrigerator near the sensor where the temperature difference data appears, so that the refrigerator cools the location where the temperature difference data appears in the cold storage, speeds up the cooling speed in the cold storage to the specified temperature, and ensures the normal storage of objects in the cold storage.

[0014] 3. In the cold storage operation abnormality detection system based on big data technology, the dynamic objects appearing in the cold storage are captured by the dynamic object capture module, and when the dynamic objects are captured, the dynamic objects are fed back to the door opening and closing detection module, so that the door opening and closing detection module transmits the opening and closing status of the cold storage door to the dynamic object capture module. When the cold storage door is closed but a dynamic object is captured, the dynamic object capture module feeds back to the warning judgment module, so that the warning judgment module issues a warning to avoid the danger of life of dynamic organisms in the cold storage due to low temperature, thereby improving the safety of the cold storage during use.

Example

[0019] In order to ensure that the cold storage can effectively freeze and preserve the objects inside, the present invention provides a cold storage operation abnormality 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 abnormality, it can be detected in time to avoid problems in the cold storage due to slow detection time. Please refer to the following Figure 1-Figure 3 As shown, the purpose of this embodiment is to include a control unit 1, a cold storage state monitoring unit 2 and a temperature detection unit 3; The control unit 1 selects the temperature of the cold air inside the cold storage through the touch screen, and after the temperature is selected, the control unit 1 transmits the selected temperature data to the cold storage status monitoring unit 2; The control unit 1 includes a temperature control module 11, which collects control temperature data of the temperature input in the touch display screen and transmits the temperature data to the temperature detection unit 3. The temperature detection unit 3 controls the refrigerator to perform cooling. The temperature control module 11 receives the cooling temperature set by the user, so that the entire system has data for cooling the cold storage, so that the temperature detection unit 3 controls 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.

[0020] The cold storage state monitoring unit 2 uses a camera to detect the opening and closing of the door of the cold storage, and transmits the detected opening and closing conditions to the temperature detection unit 3. At the same time, the cold storage state monitoring unit 2 determines the dynamic object through the image captured by the camera, and when it is determined that there is a dynamic object, it determines the opening and closing of the door, and feeds back the result to the control unit 1, which issues a warning; The cold storage state monitoring unit 2 includes a door opening and closing detection module 21, which uses a camera to shoot the door of the cold storage, and determines whether the door of the cold storage is open or closed through the image taken by the camera; The cold storage state monitoring unit 2 also includes a dynamic object capture module 22. The dynamic object capture module 22 uses a camera to shoot the situation inside the cold storage, and in the process of the camera shooting the situation inside the cold storage, it captures dynamic objects. 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 situation of the cold storage door to the dynamic object capture module 22. By sending the opening and closing situation 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 is informed of the presence of a dynamic object in the cold storage. For example, when the dynamic object capture module 22 obtains a dynamic object in the cold storage, the door of the cold storage is in an open state, which means that a staff member has entered the cold storage, and the staff member places objects in the cold storage or takes items from the cold storage, etc. This is a normal working state. However, when the door of the cold storage is closed, but the dynamic object capture module 22 captures a dynamic object in the cold storage, it means that a dynamic object is locked in the cold storage. Due to the low temperature of the cold storage, the dynamic object can be easily frozen. At this time, the dynamic object capture module 22 transmits the situation to the control unit 1, so that the control unit 1 obtains the data transmitted by the dynamic object capture module 22.

[0021] The temperature detection unit 3 receives the temperature information transmitted by the control unit 1 to control the refrigeration of the cold storage, and uses n temperature sensors to detect the temperature of each position of the cold storage during the refrigeration control process. During the detection process, the obtained temperature information is judged to determine whether the cold storage has lost temperature. At the same time, when the temperature detection unit 3 detects loss of temperature, 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 of the cold storage door to the temperature detection unit 3, and the temperature detection unit 3 judges the cause of the loss of temperature in the cold storage. At the same time, when the cold storage status monitoring unit 2 detects that the cold storage door is open, the cold storage status monitoring unit 2 feeds back to the temperature detection unit 3, so that the temperature detection unit 3 controls the refrigerator in the cold storage to perform corresponding refrigeration control on different positions in the cold storage.

[0022] The temperature detection unit 3 includes a temperature detection module 31 and a refrigeration control module 33; The temperature detection module 31 is used to control the n temperature sensors in the cold storage to detect the temperature of various places in the cold storage and obtain the temperature data of various places in the cold storage; by setting multiple temperature sensors to detect various positions in the cold storage, the temperature of each position in the cold storage is obtained, and at the same time, the n temperature sensors are installed on the side wall of the cold storage, and are arranged in a uniform array in a point shape during installation. Through the point array arrangement, the n temperature sensors can obtain the temperature change of each position in the cold storage; The refrigeration control module 33 receives the temperature data transmitted by the temperature control module 11, and controls the temperature of the n refrigerators according to the received temperature data. At the same time, when the refrigeration control module 33 controls the refrigerator 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 sensor at the corresponding position of the refrigerator to detect the temperature according to the position of the refrigerator controlled by the refrigeration control module 33 in the cold storage, so that the temperature detection module 31 detects the temperature change near the refrigerator; The refrigeration control module 33 marks the positions of 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 .

[0023] refer to Figure 3 As shown, n temperature sensors are evenly arranged on the side wall of the cold storage, and n refrigerators are arranged at the bottom of the cold storage along the side wall track of the cold storage, and the temperature sensors at the corresponding positions of the refrigerators detect the corresponding positions of the cold storage, such as Figure 3 The position corresponding to the refrigerator at point a is the temperature sensor in the range of point A.

[0024] The temperature detection unit 3 also includes a temperature loss abnormality judgment module 32; The temperature loss abnormality judgment module 32 receives the temperature data detected by the temperature detection module 31 on the internal temperature of the cold storage, and compares the received temperature data with the regulated temperature data received by the temperature control module 11, determines the temperature difference, and transmits the temperature difference data to the control unit 1. At the same time, the temperature loss abnormality judgment module 32 transmits the temperature difference data to the refrigeration control module 33, and the refrigeration control module 33 performs refrigeration control on the refrigerator at the corresponding position of the cold storage according to the temperature difference data. By controlling the refrigerator corresponding to the position where the temperature difference data appears through the refrigeration control module 33, the speed of temperature control of the cold storage can be accelerated, so that the temperature inside the cold storage can be quickly restored to the specified temperature, ensuring the safe storage of objects in the cold storage.

[0025] When calculating the temperature difference data, the temperature abnormality judgment module 32 judges the size of the temperature difference data. When judging the temperature difference data, the temperature data specified in the temperature control module 11 is subtracted from the temperature collected by the temperature sensor. At the same time, an abnormal threshold is set in the temperature abnormality judgment module 32. When the temperature difference data is greater than the abnormal threshold, the temperature 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 status of the cold storage door to the temperature abnormality judgment module 32, and the temperature abnormality judgment module 32 judges whether the cold storage is in a temperature loss condition according to the opening and closing status of the cold storage door.

[0026] The control unit 1 further includes a warning judgment module 12, which receives 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; The hypothermia abnormality judgment module 32 has the following conditions when judging whether hypothermia occurs: ①, the temperature abnormality judgment module 32 calculates the temperature difference data, but the calculated temperature difference data does not exceed the abnormal threshold, and no temperature abnormality is issued at this time. At this time, the temperature 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 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; ②, the temperature abnormality judgment module 32 calculates the temperature difference data, and the calculated temperature difference data exceeds the abnormal threshold, but when the temperature abnormality judgment module 32 feeds back to the door opening and closing detection module 21, the information transmitted to the temperature abnormality judgment module 32 by the door opening and closing detection module 21 is that the cold storage door is open. At this time, the temperature abnormality judgment module 32 does not issue a temperature abnormality, but the temperature abnormality judgment module 32 feeds back a signal that the cold storage door is open to the warning judgment module 12; ③. The temperature abnormality judgment module 32 calculates the temperature difference data. The calculated temperature difference data exceeds the abnormal threshold. When the temperature abnormality judgment module 32 feeds back to the door opening and closing detection module 21, the information transmitted to the temperature abnormality judgment module 32 by the door opening and closing detection module 21 is that the cold storage door is closed. At this time, the temperature abnormality judgment module 32 sends a temperature abnormality signal. The warning judgment module 12 issues a warning after receiving the temperature abnormality signal. At the same time, the temperature abnormality judgment module 32 transmits information to the refrigeration control module 33, so that the refrigeration control module 33 performs refrigeration control on the refrigerator 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 is restored to the specified temperature; ④. The temperature loss abnormality judgment module 32 calculates the temperature difference data. When the information transmitted to the temperature loss abnormality judgment module 32 by the door opening and closing detection module 21 is that the cold storage door is open, and the temperature data in the cold storage collected by the temperature detection module 31 gradually decreases from close to the door to far away from the door, it indicates that the cold storage is in normal temperature loss. Because when the cold storage door is opened, the cold air in the cold storage will flow outward from the door, causing the cold air near the door to be lost, while the cold air inside the cold storage is not lost. In the process of opening the door, the cold air will fall due to gravity, causing the temperature near the door to rise, while the temperature far away from the door will not rise. Moreover, the closer the position in the cold storage is to the door, the more the temperature rises. However, the temperature rise caused by the opening of the door is normal. At this time, the temperature loss abnormality judgment module 32 does not issue a temperature loss abnormality, but the temperature loss abnormality judgment module 32 feeds back a signal that the cold storage door is open to the warning judgment module 12. When the information transmitted to the hypothermia abnormality judgment module 32 by the door opening and closing detection module 21 is that the door of the cold storage is closed, and the temperature data in the cold storage collected by the temperature detection module 31 is chaotic from the temperature data near the door to the temperature data far from the door, that is, the temperature in the cold storage is not high near the door, but the temperature is higher somewhere inside the cold storage than other locations. This indicates that there is a problem with the refrigeration situation at that location, which may be due to damage to the refrigerator or a problem with the side wall of the cold storage. This indicates that the cold storage is in a hypothermia state, and the hypothermia abnormality judgment module 32 sends a hypothermia abnormality signal. The warning judgment module 12 issues a warning after receiving the hypothermia abnormality signal, and the user performs on-site diagnosis to ensure that the cold storage can store items normally.

[0027] When the warning judgment module 12 receives the abnormal hypothermia situation judged by the abnormal hypothermia judgment module 32, it displays a warning through the touch screen; When the dynamic object capture module 22 captures a dynamic object, and the information transmitted by the door opening and closing detection module 21 is that the cold storage door is in a closed state, the dynamic object capture module 22 feeds back to the warning judgment module 12, and the warning judgment module 12 performs a corresponding warning operation.

[0028] Summary of usage process: The temperature of the cold storage is set by the temperature control module 11, and 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 hypothermia abnormality judgment module 32. The hypothermia abnormality 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 position corresponding to the sensor where the temperature difference data appears, so that the refrigerator is cooled to adjust the temperature of the position. Especially when new items are put into the cold storage, the temperature in the cold storage changes greatly. At this time, it is necessary to accurately control the refrigerator to cool through the refrigeration control module 33 to accelerate the temperature in the cold storage to return to the specified value.

[0029] When the temperature difference data calculated by the hypothermia abnormality judgment module 32 is greater than the abnormal threshold, the hypothermia abnormality judgment module 32 sends a signal to the door opening and closing detection module 21, so that the door opening and closing detection module 21 sends the status 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 is that the cold storage door is in an open state, the hypothermia abnormality judgment module 32 can feedback the status of the cold storage door opening to the warning judgment module 12. When the hypothermia abnormality judgment module 32 receives information that the cold storage door is in a closed state, it indicates that a fault has occurred in the cold storage, such as damage to the refrigerator or damage to the outer wall of the cold storage. At this time, the hypothermia abnormality judgment module 32 feeds back to the warning judgment module 12, so that the warning judgment module 12 issues an alarm.

[0030] 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 the dynamic objects, the dynamic object capture module 22 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 status of the cold storage door to the dynamic object capture module 22. When the cold storage door is in an open state, the dynamic object capture module 22 ignores the information. When the cold storage door is in a closed state, the dynamic object capture module 22 transmits such information to the warning judgment module 12, and the warning judgment module 12 issues a warning. The type of warning may be a light warning, a sound warning, etc., to prevent the organism from hypothermia in the cold storage.
