Description

Technical Field

[0001] The present application relates to the field of defrosting technology, and in particular to a blood bag defrosting system and method. Background Art

[0002] During the storage of blood bags, the blood bags are usually frozen in a quick freezer and then transported to a low-temperature cold storage for storage manually or automatically. Since the temperature of the blood bags after quick freezing is relatively low and there is a large temperature difference between the quick freezing temperature and the external ambient temperature, water mist is easily generated on the surface of the blood bags during the transportation of the blood bags from the quick freezer to the cold storage, thus affecting the accuracy of the recognition of the barcode information on the blood bags before entering the cold storage. Therefore, how to remove the water mist generated on the surface of the blood bags has become a problem that needs to be solved urgently. Summary of the invention

[0003] Based on this, it is necessary to provide a blood bag defrosting system and method that can accurately remove water mist generated on the surface of the blood bag in order to address the above technical problems.

[0012] In one of the embodiments, the control module is further configured to instruct the defrosting module to stop defrosting if the blood bag detection result is that no blood bag exists.

[0013] In one embodiment, the system further includes a dehumidification module; the dehumidification module is connected to the control module; the temperature and humidity detection module is also used to collect temperature and humidity data of the target area at a preset time interval, and send the temperature and humidity data to the control module;

[0014] The control module is also used to instruct the dehumidification module to dehumidify the target area if the temperature and humidity data of the target area do not meet the preset temperature and humidity conditions, until the temperature and humidity data of the target area meet the preset temperature and humidity conditions.

[0015] In one of the embodiments, the control module is further used to determine a target temperature and humidity level according to the temperature and humidity detection results, and determine a target defrost level corresponding to the target temperature and humidity level based on a correspondence between the temperature and humidity level and the defrost level.

[0016] The above-mentioned blood bag defrosting system performs blood bag detection on the target area through the blood bag detection module to obtain the blood bag detection result, and sends the blood bag detection result to the control module. The temperature and humidity detection module detects the temperature and humidity of the target area to obtain the temperature and humidity detection result, and sends the temperature and humidity detection result to the control module. The control module is used to determine the target defrost level according to the temperature and humidity detection result if the blood bag detection result shows that there is a blood bag. The defrost module defrosts the blood bags in the target area according to the wind speed corresponding to the target defrost level, so as to achieve accurate removal of frost formed on the surface of the blood bag, thereby improving the accuracy of blood bag identification; in addition, defrosting in the form of ventilation can better protect the blood quality in the blood bag from external influences, thereby ensuring the safety of the blood.

If the blood bag detection result is that there is a blood bag, the target defrost level is determined according to the temperature and humidity detection result, and the defrost module is controlled to defrost the blood bags in the target area based on the wind speed corresponding to the target defrost level.

[0039] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0040] In an exemplary embodiment, Figure 1As shown, a blood bag defrosting system is provided, which includes a blood bag detection module 102, a temperature and humidity detection module 104, a defrosting module 108 and a control module 106. The blood bag detection module 102, the temperature and humidity detection module 104 and the defrosting module 108 are respectively connected to the control module 106 and communicate with each other; the blood bag detection module 102 is used to perform blood bag detection on the target area, obtain the blood bag detection result, and send the blood bag detection result to the control module 106; the temperature and humidity detection module 104 is used to detect the temperature and humidity of the target area, obtain the temperature and humidity detection result , and sends the temperature and humidity detection results to the control module 106; the control module 106 can be used to determine the target defrost level according to the temperature and humidity detection results if the blood bag detection result is that there is a blood bag, and send the target defrost level to the defrost module 108; the defrost module 108 is used to defrost the detected blood bag according to the wind speed corresponding to the target defrost level, so as to achieve accurate defrosting of the blood bag at a wind speed matching the environment, avoid insufficient defrosting due to a smaller wind speed, and also avoid the influence of a larger wind speed on the blood quality in the blood bag, thereby achieving accurate defrosting and improving energy utilization.

[0041] The target area refers to the area where the blood bag is defrosted. The blood bag is detected in the target area, and the blood bag is defrosted after the blood bag is detected. The target area can be any area in the blood bag transportation process. For example, in the process of transporting the blood bag from the quick-freezing storage to the cold storage, the blood bag barcode needs to be identified before the blood bag is stored in the cold storage. The blood bag needs to be defrosted before the blood bag barcode is identified. Then, the target area can be the area before entering the cold storage. It can be understood that the size and position of the target area can be set according to the actual application scenario.

[0042] The blood bag detection result refers to the detection result of whether a blood bag exists, that is, the blood bag detection result includes whether a blood bag exists or not. The blood bag detection module 102 can perform blood bag detection on the target area at preset intervals, or can perform blood bag detection on the target area in real time.

[0043] Optionally, the blood bag detection module 102 can perform blood bag detection on the target area through a blood bag recognition algorithm or a blood bag recognition model. The blood bag recognition model is trained based on a blood bag image sample training set. The blood bag image sample training set includes multiple blood bag image samples. The blood bag image sample set may include blood bag image samples of various types and in various placement forms. The manner in which the blood bag detection module 102 performs blood bag detection is not specifically limited herein. By performing blood bag detection on the target area through the blood bag recognition model, the blood bag detection result of the target area can be obtained quickly and accurately, thereby improving the efficiency and accuracy of obtaining the blood bag detection result.

[0044] The temperature and humidity detection result refers to the detection result that characterizes the temperature and humidity conditions. The temperature and humidity detection result may include temperature detection results and humidity detection results. The temperature detection result is such as temperature detection data, and the humidity detection result is such as humidity detection data. The temperature detection result can be obtained by detecting a temperature sensor or a temperature measuring instrument, and the humidity detection result can be obtained by detecting a humidity sensor or a humidity measuring instrument. The temperature and humidity detection result can also be obtained by detecting a temperature and humidity sensor. Optionally, the temperature and humidity detection results can be determined by setting temperature and humidity sensors at different positions in the target area, and by using the temperature and humidity data detected by multiple temperature and humidity sensors. Compared with a single sensor detection, the detection result of multiple sensors is more accurate. For example, the final temperature and humidity detection result is obtained by calculating the average or median of multiple temperature and humidity data detected by multiple temperature and humidity sensors. The temperature and humidity detection module 104 can perform temperature and humidity detection on the target area at intervals of a preset duration, or it can perform temperature and humidity detection on the target area when receiving the corresponding detection trigger condition.

[0045] Optionally, the blood bag detection module 102 may send all blood bag detection results to the control module 106, and the control module 106 may identify the blood bag detection results. Alternatively, the blood bag detection module 102 may send the blood bag detection results to the control module 106 when identifying that the blood bag detection results indicate that a blood bag exists. In the first case, after obtaining the blood bag detection results sent by the blood bag detection module 102, the control module 106 may judge the blood bag detection results. If the blood bag detection results indicate that a blood bag exists, the temperature and humidity detection results sent by the temperature and humidity detection module 104 are obtained, and the target defrost level is determined according to the temperature and humidity detection results, and the target defrost level is sent to the defrost module 108. That is, the blood bag detection results are identified by the control module 106, and the control module performs unified identification and control to avoid information conflicts, thereby improving control accuracy. In the second case, the blood bag detection results obtained by the control module 106 are all blood bag detection results corresponding to the existence of blood bags, that is, the blood bag detection module 102 judges the blood bag detection results after obtaining the blood bag detection results. If the blood bag detection result is that there is a blood bag, the blood bag detection result is sent to the control module 106, and then the control module 106 determines the target defrost level according to the obtained temperature and humidity detection results, and sends the defrost level to the defrost module 108. If the blood bag detection result is that there is no blood bag, the blood bag detection module 102 will not send the blood bag detection result of the absence of blood bag to the control module 106. That is, the blood bag identification result is identified by the blood bag identification module, and when it is identified that there is a blood bag, the blood bag identification result is sent to the control module, which triggers the control module to obtain the temperature and humidity detection results to determine the target defrost level. In other words, only when there is a blood bag, the temperature and humidity detection and the determination of the target defrost level are triggered for defrosting, which can greatly reduce the energy consumption of the system.

[0046] Optionally, the defrost level may include multiple levels, and the target defrost level may be any defrost level. Different defrost levels correspond to different wind speeds. Generally, the higher the defrost level, the greater the corresponding wind speed. A mapping relationship between the defrost level and the wind speed may be established in advance. After determining the defrost level, the corresponding wind speed may be quickly determined, so that the blood bag is defrosted by wind of the corresponding wind speed, thereby improving the defrosting efficiency, that is, the wind of the corresponding wind speed is blown toward the blood bag, and the air convection around the blood bag is strengthened, so that the frost condensed on the surface of the blood bag melts, thereby achieving defrosting of the blood bag. The defrost module may include a fan, that is, defrosting is performed by blowing air from the fan.

[0047] In an optional embodiment, when the blood bag detection module 102 detects the presence of a blood bag, the blood bag detection result is sent to the temperature and humidity detection module 104, triggering the temperature and humidity detection module 104 to detect the temperature and humidity, and then sending the detected temperature and humidity data to the control module 106. The control module 106 only needs to determine the corresponding defrost level based on the temperature and humidity data, which further reduces the data processing amount of the control module, improves the operation speed of the control module, and thus improves the efficiency of determining the target defrost level. The blood bag detection module 102 performs blood bag detection on the target area to obtain a blood bag detection result. If the blood bag detection result indicates that a blood bag exists, the blood bag detection result is sent to the temperature and humidity detection module 104. After receiving the blood bag detection result indicating that a blood bag exists sent by the blood bag detection module, the temperature and humidity detection module 104 detects the temperature and humidity of the target area to obtain a temperature and humidity detection result, and sends the temperature and humidity detection result to the control module 106. After receiving the temperature and humidity detection result sent by the temperature and humidity detection module 104, the control module 106 determines a target defrost level according to the temperature and humidity detection result, and sends the target defrost level to the defrost module. The defrost module defrosts the blood bags in the target area according to the wind speed corresponding to the target defrost level. If the blood bag detection result indicates that a blood bag does not exist, the blood bag detection result is sent to the control module 106, and the control module 106 instructs the defrost module to stop defrosting.

[0048] In another optional embodiment, the difference from the aforementioned embodiment lies in that, in the aforementioned embodiment, the temperature and humidity detection results of the temperature and humidity detection module are obtained only when the control module 106 recognizes that the blood bag detection result is the presence of a blood bag, while in this embodiment, the control module 106 can simultaneously obtain the blood bag detection result and the temperature and humidity detection result at a predetermined frequency. When the obtained blood bag detection result is the presence of a blood bag, it is necessary to determine the temperature and humidity detection result corresponding to the blood bag detection result, that is, to determine the temperature and humidity detection result within the same time range as the blood bag detection result. The blood bag detection module 102 performs blood bag detection on the target area to obtain the blood bag detection result. If the blood bag detection result shows that there is a blood bag, the blood bag detection result is sent to the control module 106; the temperature and humidity detection module 104 detects the temperature and humidity of the target area to obtain the temperature and humidity detection result, and sends the temperature and humidity detection result to the control module 106. The control module 106 selects the temperature and humidity detection result corresponding to the blood bag detection result to determine the target defrost level, and then sends the target defrost level to the defrost module 108, so that the defrost module 108 defrosts the blood bags in the target area according to the wind speed corresponding to the target defrost level. The blood bag defrosting system in this embodiment takes the control module as the control center, and other modules work according to predetermined conditions. For example, the blood bag detection module only needs to send the blood bag detection result to the control module regularly, and the temperature and humidity detection module only needs to send the temperature and humidity detection result to the control module regularly, and then the control module performs overall control, reducing the interaction between other modules except the control module, which can improve the system operation efficiency. Among them, the blood bag test result and the temperature and humidity test result can both include the corresponding blood bag identification or blood tray identification, so that the temperature and humidity test result corresponding to the blood bag test result is selected according to the blood bag identification or blood tray identification, that is, the temperature and humidity test result corresponding to the blood bag test result refers to the blood bag test result and the temperature and humidity test result corresponding to the same blood tray identification or blood bag identification. Multiple blood bags can be placed in the same blood tray, the blood tray identification is used to uniquely identify the blood tray, and the blood bag identification is used to uniquely identify the blood bag.

[0049] Alternatively, different from the aforementioned embodiment, the aforementioned embodiment obtains the temperature and humidity detection results of the temperature and humidity detection module 104 after identifying that the blood bag detection result is the presence of a blood bag, and the temperature and humidity detection module 104 is continuously in detection, while in this embodiment, after the control module 106 identifies that the blood bag detection result is the presence of a blood bag, it instructs the temperature and humidity detection module 104 to detect the temperature and humidity of the target area, and then obtains the detected temperature and humidity detection results, which can reduce system power consumption. The blood bag detection module 102 performs blood bag detection on the target area, obtains the blood bag detection result, and sends the blood bag detection result to the control module 106. After obtaining the blood bag detection result, the control module 106 judges the blood bag detection result. If the blood bag detection result shows that there is a blood bag, the temperature and humidity detection module 104 is instructed to detect the temperature and humidity of the target area to obtain the temperature and humidity detection result of the target area. The control module 106 obtains the temperature and humidity detection result sent by the temperature and humidity detection module 104, determines the target defrost level according to the temperature and humidity detection result, and sends the target defrost level to the defrost module 108 to instruct the defrost module 108 to defrost the blood bags in the target area according to the wind speed corresponding to the target defrost level.

[0050] The above-mentioned blood bag defrosting system performs blood bag detection on the target area through the blood bag detection module to obtain the blood bag detection result, and sends the blood bag detection result to the control module. The temperature and humidity detection module detects the temperature and humidity of the target area to obtain the temperature and humidity detection result, and sends the temperature and humidity detection result to the control module. The control module is used to determine the target defrost level according to the temperature and humidity detection result if the blood bag detection result shows that there is a blood bag. The defrost module defrosts the blood bags in the target area according to the wind speed corresponding to the target defrost level, which can achieve accurate defrosting of the blood bags at a wind speed matching the environment, avoid insufficient defrosting at a smaller wind speed, and also avoid excessive heat from the blood bags being taken away by a larger wind speed, which affects the blood quality in the blood bags. While achieving accurate defrosting, the energy utilization rate is improved, thereby improving the accuracy of blood bag identification. In addition, defrosting in the form of ventilation can better protect the blood quality in the blood bags from external influences, thereby ensuring the safety of the blood.

[0051] In some embodiments, the blood bag detection module is also used to send the blood bag detection result to the temperature and humidity detection module if the blood bag detection result shows that a blood bag exists; the temperature and humidity detection module is also used to detect the temperature and humidity of the target area when receiving the blood bag detection result, obtain the temperature and humidity detection result, and send the temperature and humidity detection result to the control module.

[0052] like Figure 2As shown, the blood bag detection module 102 is connected to the temperature and humidity detection module 104. The blood bag detection module 102 performs blood bag detection on the target area to obtain a blood bag detection result. If the blood bag detection result shows that a blood bag exists, the blood bag detection result is sent to the temperature and humidity detection module 104. When receiving the blood bag detection result, the temperature and humidity detection module 104 detects the temperature and humidity of the target area to obtain a temperature and humidity detection result. The temperature and humidity detection module 104 sends the temperature and humidity detection result to the control module 106. The control module 106 determines the target defrost level according to the temperature and humidity detection results, and then sends the target defrost level to the defrost module 108. The defrost module 108 defrosts the blood bags in the target area according to the wind speed corresponding to the target defrost level.

[0053] Optionally, if the blood bag detection result obtained by the blood bag detection module 102 is that there is no blood bag, the blood bag detection result is directly sent to the control module 106, and the control module 106 instructs the defrost module 108 to stop defrosting after receiving the blood bag detection result. Alternatively, it can also be understood that after the control module 106 receives the blood bag detection result that there is no blood bag, it determines the target defrost level as the defrost level corresponding to no defrosting, and the defrost module 108 stops defrosting the blood bags in the target area. Stopping defrosting when there is no blood bag can reduce the defrosting power consumption of the defrost module and increase the service life of the defrost module.

[0054] In the present embodiment, when the blood bag detection result indicates that a blood bag exists, the blood bag detection result is sent to the temperature and humidity detection module. The temperature and humidity detection module detects the temperature and humidity of the target area based on the trigger of receiving the blood bag detection result, obtains the temperature and humidity detection result, and then sends the temperature and humidity detection result to the control module. The control module is not required to judge the blood bag detection result, and the temperature and humidity detection module detects the temperature and humidity only when a blood bag exists, and does not perform temperature and humidity detection in real time, thereby reducing the overall operating power consumption of the blood bag defrosting system.

[0055] In some embodiments, the system further includes a defrost frame and a blood bag transmission module. The blood bag detection module, the temperature and humidity detection module, the defrost module and the control module are arranged on the defrost frame. The blood bag transmission module includes a driving mechanism and a transmission mechanism. The driving mechanism is used to drive the transmission mechanism to move so as to drive the blood bag located on the transmission mechanism to pass through the target area formed between the defrost module and the blood bag detection module.

[0056] Among them, the blood bag transmission module is used for blood bag transmission, and can transmit the blood bag from the starting position to the target position, and the target position is the end position of the blood bag transmission. In actual application scenarios, blood bags can be placed in blood trays, and each blood tray can hold multiple blood bags. The blood bag transmission module can transmit the blood tray containing blood bags, and then transmit the blood tray containing blood bags to the target position. The defrost frame is used to carry the blood bag detection module, the temperature and humidity detection module, the defrost module and the control module. The driving mechanism is used to drive the transmission mechanism to move, and the driving mechanism may include driving parts such as motors and motors and transmission parts such as gears, racks, chains, and belts. The transmission mechanism is used to carry blood bags, and the transmission mechanism may include, for example, a conveyor belt, a conveyor platform, etc. The driving mechanism can drive the blood bags on the transmission mechanism to pass through the target area formed between the defrost module and the blood bag detection module. The target area is an area for defrosting the blood bags.

[0057] In an optional application scenario, the transmission path of the blood bag transmission module from the starting position to the target position includes a target area. When the blood bag transmission module transmits the blood bag to the target area, the blood bag detection module 102 can detect the presence of a blood bag in the target area, that is, the blood bag detection result is that a blood bag exists; and when the blood bag transmitted by the blood bag transmission module does not reach the target area, or the blood bag transmission module does not transmit a blood bag, the blood bag detection module 102 detects that no blood bag exists in the target area.

[0058] Optionally, instead of forming the target area by the defrost module and the blood bag detection module, the target area can also be formed by the defrost module, the blood bag detection module and the temperature and humidity detection module, that is, the target area is the common action area of ​​the defrost module, the blood bag detection module and the temperature and humidity detection module, which can make the range of the target area more accurate and more conducive to defrosting the blood bags.

[0059] Exemplarily, when the driving mechanism drives the blood bag on the transmission mechanism to enter the preset range of the target area, the blood bag detection module can detect the blood bag, that is, the blood bag detection result is that the blood bag exists. In other words, if the blood bag enters the target area but is not within the preset range, the blood bag detection module cannot detect the existence of the blood bag. The preset range can be the range of entering the target area in the direction of blood bag transmission, and the size of the preset range can be set according to the actual application scenario.

[0060] In this embodiment, by arranging the blood bag detection module, the temperature and humidity detection module, the defrosting module and the control module on the defrosting frame, the structure of the blood bag defrosting system can be made more compact and save space. In addition, the driving mechanism of the blood bag transmission module drives the transmission mechanism to move, so as to drive the blood bag on the transmission mechanism to pass through the target area formed between the defrosting module and the blood bag detection module, so as to facilitate the detection of the blood bag during the blood bag transmission process, and perform blood bag detection and defrosting around the target area, so as to improve the accuracy of blood bag defrosting.

[0061] In some embodiments, the control module is further configured to instruct the defrost module to stop defrosting if the blood bag detection result shows that no blood bag exists.

[0062] The control module 106 may receive the blood bag detection result sent by the blood bag detection module 102 indicating that there is no blood bag, and then instruct the defrost module to stop defrosting, or the control module may receive the blood bag detection result sent by the blood bag detection module 102, and instruct the defrost module to stop defrosting if the blood bag detection result indicates that there is no blood bag.

[0063] In this embodiment, when the blood bag detection result shows that there is no blood bag, the defrosting module is instructed to stop defrosting, thereby saving energy consumption and reducing system energy consumption.

[0064] In some embodiments, the above system also includes a dehumidification module; the dehumidification module is connected to the control module; the temperature and humidity detection module is also used to collect the temperature and humidity data of the target area at every preset time interval, and send the temperature and humidity data to the control module; the control module is also used to instruct the dehumidification module to dehumidify the target area if the temperature and humidity data of the target area does not meet the preset temperature and humidity conditions until the temperature and humidity data of the target area meet the preset temperature and humidity conditions.

[0065] For example, Figure 3 As shown, the dehumidification module 110 is connected to the control module 106 for communication, and the temperature and humidity detection module 104 collects the temperature and humidity data of the target area at each preset time interval, and sends the temperature and humidity data to the control module 106. After receiving the temperature and humidity data sent by the temperature and humidity module 104, the control module 106 determines whether the temperature and humidity data meet the preset temperature and humidity conditions. If the temperature and humidity data do not meet the preset temperature and humidity conditions, the dehumidification module 110 is instructed to dehumidify the target area until the temperature and humidity data of the target area meet the preset temperature and humidity conditions. If the temperature and humidity data meet the preset temperature and humidity conditions, the dehumidification module 110 is instructed to stop dehumidification. That is, the temperature and humidity data are collected and the temperature and humidity conditions are judged at each preset time interval to determine whether dehumidification is needed. Compared with real-time temperature and humidity data collection and temperature and humidity condition judgment, it can reduce system power consumption while achieving dehumidification.

[0066] The temperature and humidity conditions refer to conditions where dehumidification is not required, for example, the temperature and humidity conditions may be that the temperature and humidity data are within a preset temperature and humidity range, or the humidity data is less than a preset humidity and the temperature data is less than a preset temperature. It is understandable that the preset temperature and humidity range may include a temperature and humidity at which the blood bag does not frost or a temperature and humidity close to which the blood bag does not frost.

[0067] Optionally, the dehumidification module 110 can cool the air in the target area, such as by cooling and / or ventilating the air, thereby converting the moisture in the cooled air into liquid water and discharging it, thereby dehumidifying the target area. Compared with the heating and dehumidification solution, the quality of the blood in the blood bag can be prevented from being affected by temperature changes.

[0068] In this embodiment, if the temperature and humidity data of the target area do not meet the preset temperature and humidity conditions, the target area is dehumidified by the dehumidification module until the temperature and humidity data of the target area meet the preset temperature and humidity conditions, thereby increasing the time that the temperature and humidity of the target area meet the preset temperature and humidity conditions, so that the humidity in the target area is lower, which can reduce the amount of frost condensed on the surface of the blood bag. When the blood bag is detected and defrosted, the wind speed of the defrost module for defrosting can be reduced, and the defrosting speed can be accelerated, thereby improving the defrosting efficiency of the blood bag.

[0069] In an exemplary embodiment, the control module is also used to determine the target temperature and humidity level according to the temperature and humidity detection results, and determine the target defrost level corresponding to the target temperature and humidity level based on the corresponding relationship between the temperature and humidity level and the defrost level.

[0070] Among them, the correspondence between the temperature and humidity levels and the defrost levels can be pre-established. For example, the temperature and humidity levels include level one temperature and humidity, level two temperature and humidity, and level three temperature and humidity. The defrost levels include level one defrost, level two defrost, and level three defrost. Then, level one temperature and humidity correspond to level one defrost, level two temperature and humidity correspond to level two defrost, and level three temperature and humidity correspond to level three defrost. It can be understood that the correspondence between the temperature and humidity levels and the defrost levels is not limited to this.

[0071] Optionally, the temperature and humidity detection results include temperature and humidity data, and the target temperature and humidity level corresponding to the temperature and humidity data can be determined according to the range of the temperature and humidity data, and then the target defrost level corresponding to the target temperature and humidity level can be determined based on the correspondence between the temperature and humidity level and the defrost level, so that the target defrost level can be determined conveniently and quickly.

[0072] In this embodiment, the control module determines the target temperature and humidity level according to the temperature and humidity detection results, and determines the target defrost level corresponding to the target temperature and humidity level based on the correspondence between the target temperature and humidity level and the defrost level. The target defrost level can be determined conveniently and quickly, thereby quickly instructing the defrost module to defrost the blood bags in the target area based on the wind speed corresponding to the target defrost level, thereby improving the defrosting efficiency of the blood bags.

[0073] In an exemplary embodiment, Figure 4As shown, the blood bag defrosting system includes a defrosting frame 100, a blood bag transmission module 112, a blood bag detection module 102, a temperature and humidity detection module 104, a control module 106 and a defrosting module 108, wherein the blood bag detection module 102, the temperature and humidity detection module 104, the control module 106 and the defrosting module 108 are arranged on the defrosting frame 100; the blood bag transmission module 112 may include a driving mechanism and a transmission mechanism, etc. The driving mechanism may be used to drive the transmission mechanism to move, thereby driving the blood bag on the transmission mechanism to pass through the target area formed between the defrosting module 108 and the blood bag detection module 102, and the transmission mechanism may be, for example, a motor. The transmission mechanism may be used to transmit a carrier carrying a blood bag, and the carrier may be a blood tray or a blood frame, etc. For example, the blood tray is placed on a conveyor belt, and the blood bag in the blood tray is transmitted through the conveyor belt. The blood bag transmission module 112 may also include a transfer mechanism, and the transfer mechanism may be, for example, a mobile vehicle. In the case where the blood bag cannot be transmitted through the transmission mechanism, the blood bag may be transferred from one position to another different position through the transfer mechanism. The defrost module 108 is arranged above the blood bag transmission module 112 in the target area, that is, the air outlet of the defrost module 108 is facing the blood bag transmitted by the blood bag transmission module 112. The defrost module 108 includes, for example, a fan, which may be one or more fans, and the fan can ventilate and defrost any position in the target area. It is easy to understand that the blood bag transmission module 112 can be arranged on the defrost frame 100, or it can be arranged separately from the defrost frame 100. The blood bag detection module 102 is arranged at the entrance of the blood bag transmission direction in the target area, that is, the blood bag detection module 102 is arranged on the side of the position where the blood bag just enters the target area when the blood bag is transmitted. It can be understood that the blood bag transmission module 112 transmits the blood bag first into the target area, then passes through the target area, and finally moves away from the target area. When the blood bag just enters the target area, the blood bag detection module 102 can obtain the blood bag detection result by shooting the blood bag image and performing blood bag detection based on the blood bag image; the blood bag detection module 102 may include a camera, an image processing chip, etc. The temperature and humidity detection module 104 may include a temperature sensor and a humidity sensor, and the number of the temperature sensor or the humidity sensor may be one or more. The control module 106 may be a control device including a processor, and the control device may be a terminal or a server, etc.

[0074] If the blood bag detection result is that there is a blood bag, the blood bag detection module 102 sends a first signal to the temperature and humidity detection module 104. The temperature and humidity detection module 104 detects the temperature and humidity of the target area based on the first signal, obtains the temperature and humidity detection result, and sends the temperature and humidity detection result to the control module 106. The control module 106 determines the target defrost level based on the temperature and humidity detection result, and sends the target defrost level to the defrost module 108. The defrost module 108 ventilates and defrosts the target area according to the wind speed corresponding to the target defrost level. If the blood bag detection result is that there is no blood bag, the blood bag detection module 102 sends a second signal to the control module 106. The control module 106 instructs the defrost module 108 to stop defrosting based on the second signal. The first signal and the second signal are different signals. For example, the first signal is a high-order signal, and the second signal is a low-order signal. The high-order signal is such as a high-level signal, and the low-order signal is such as a low-level signal.

[0075] For example, taking the control temperature as a fixed value, if the temperature and humidity detection results of the target area are 25°C (degrees Celsius) and the humidity is greater than or equal to 80%, the absolute humidity of the ambient air is 18.43g / m 3 , the corresponding target defrost level is level 4 defrost (the highest defrost level); if the temperature and humidity detection results of the target area are 25°C and the humidity is between 60% and 80%, the absolute humidity of the ambient air is 14.97-18.43g / m 3 , the corresponding target defrost level is level 3 defrost (the highest defrost level); if the temperature and humidity detection results of the target area are 25°C and the humidity is between 35% and 65%, the absolute humidity of the ambient air is 8.06-14.97g / m 3 , the corresponding target defrost level is level 2 defrost; if the temperature and humidity detection results of the target area are 25°C and humidity is less than 35%, the absolute humidity of the ambient air is less than 8.06g / m 3 , the corresponding target defrost level is level one defrost (the lowest defrost level). The lower the defrost level, the lower the corresponding wind speed. It can be understood that the defrost level in the actual application scenario is not limited to the four levels in the above example, but can also be other numbers of defrost levels, the temperature is not limited to being fixed at 25°C, but can also be other temperatures or temperatures that change in real time, and the corresponding humidity range is not limited to the above humidity range.

[0076] The blood bag defrosting system in the above-mentioned embodiment detects the temperature and humidity of the environment in which the blood bags are located when detecting the presence of blood bags, obtains the temperature and humidity detection results, determines the target defrost level based on the temperature and humidity detection results, and then defrosts the blood bags based on the wind speed corresponding to the target defrost level. The blood bags can be accurately defrosted at a wind speed that matches the environment, thereby preventing a lower wind speed from failing to fully defrost, and also preventing a higher wind speed from taking away too much heat from the blood bags, thereby affecting the quality of the blood in the blood bags. While achieving accurate defrosting, the energy utilization rate is improved, thereby improving the accuracy of blood bag identification. In addition, defrosting in the form of ventilation can better protect the quality of the blood in the blood bags from external influences, thereby ensuring the safety of the blood.

[0077] In an exemplary embodiment, Figure 5 As shown, a blood bag defrosting method is provided, and the method is described by taking the control module applied to the above blood bag defrosting system as an example. It can be understood that the control module can be a server or a terminal. The method includes the following steps 502 to 508.

[0078] Step 502, obtaining a blood bag detection result obtained by the blood bag detection module performing blood bag detection on the target area.

[0079] The control module obtains the blood bag detection result obtained by the blood bag detection module for the target area, wherein the blood bag detection module can perform blood bag detection on the target area at a preset interval, or can perform blood bag detection on the target area in real time to obtain the blood bag detection result corresponding to each detection, and then the blood bag detection module can send the detected blood bag detection result to the control module. The target area refers to the area where the blood bag is defrosted, and the target area can be selected and set according to the actual application scenario.

[0080] Step 504: Acquire the temperature and humidity detection results obtained by the temperature and humidity detection module for detecting the temperature and humidity of the target area.

[0081] Among them, the temperature and humidity detection module can detect the temperature and humidity of the target area at preset intervals, or can detect the temperature and humidity of the target area in real time to obtain corresponding temperature and humidity detection results. It can also be that when the blood bag detection module detects a blood bag, when a first signal is sent to the temperature and humidity detection module, the temperature and humidity detection module is triggered to detect the temperature and humidity of the target area to obtain the temperature and humidity detection result. Alternatively, when the blood bag detection result is that there is a blood bag, the control module sends a temperature and humidity detection instruction to the temperature and humidity detection module to instruct the temperature and humidity detection module to detect the temperature and humidity of the target area to obtain the temperature and humidity detection result, and then the temperature and humidity detection module sends the temperature and humidity detection result to the control module.

[0082] Step 506: If the blood bag detection result indicates that a blood bag exists, determine a target defrost level according to the temperature and humidity detection result.

[0083] Among them, the temperature and humidity detection results include temperature and humidity data, and the corresponding target temperature and humidity level can be determined according to the range of the temperature and humidity data, and then the target defrost level corresponding to the target temperature and humidity level can be determined.

[0084] Optionally, the temperature and humidity data can be matched with the temperature and humidity data range corresponding to the preset temperature and humidity level, and the preset temperature and humidity level matching the temperature and humidity data can be used as the target temperature and humidity level. Then, based on the correspondence between the temperature and humidity level and the defrost level, the target temperature and humidity level corresponding to the target temperature and humidity level can be determined.

[0085] Step 508: Control the defrost module to defrost the blood bags in the target area based on the wind speed corresponding to the target defrost level.

[0086] Different defrost levels correspond to different wind speeds. After determining the target defrost level, the control module controls the defrost module to defrost the blood bags in the target area based on the wind speed corresponding to the target defrost level. In a specific application scenario, the defrost module can be a fan, which generates a wind speed corresponding to the target defrost level and blows toward the blood bags in the target area, so that the air convection speed around the blood bags is accelerated to melt the frost condensed on the surface of the blood bags.

[0087] It can be understood that the explanation of the terms and steps in the blood bag defrosting method in the above embodiment can refer to the explanation and description of the corresponding terms and steps in the blood bag defrosting system in the above embodiment, which will not be repeated here.

[0088] The above-mentioned blood bag defrosting method obtains the blood bag detection result obtained by the blood bag detection module when detecting the blood bags in the target area, and the temperature and humidity detection result obtained by the temperature and humidity detection module when detecting the temperature and humidity in the target area. If the blood bag detection result is that there is a blood bag, the target defrost level is determined according to the temperature and humidity detection result, and the defrost module is controlled to defrost the blood bags in the target area based on the wind speed corresponding to the target defrost level. This can realize defrosting according to the corresponding wind speed determined according to the ambient temperature and humidity, that is, defrosting is performed at a wind speed that matches the ambient temperature and humidity. This can maximize the use of energy while performing accurate defrosting, thereby improving the utilization rate of energy. In addition, defrosting the blood bags by ventilation can avoid the external environment from affecting the quality of blood in the blood bags, thereby ensuring the safety of the blood.

[0089] In some embodiments, the method further comprises controlling the defrost module to stop defrosting if the blood bag detection result is that no blood bag exists.

[0090] The defrosting can be stopped by stopping ventilation to the target area. The description of this step can refer to the description of the corresponding steps in the above-mentioned blood bag defrosting system, which will not be repeated here.

[0091] In this embodiment, when the blood bag detection result shows that there is no blood bag, the defrosting module is instructed to stop defrosting, thereby saving energy consumption and reducing system energy consumption.

[0092] In some embodiments, determining the target defrost level according to the temperature and humidity detection results includes:

[0093] Determine the target temperature and humidity level according to the temperature and humidity detection results; determine the target defrost level corresponding to the target temperature and humidity level based on the corresponding relationship between the temperature and humidity level and the defrost level. The description of this step can refer to the description of the corresponding step in the above blood bag defrosting system, which will not be repeated here.

[0094] In this embodiment, by determining the target temperature and humidity level according to the temperature and humidity detection results, and determining the target defrost level corresponding to the target temperature and humidity level based on the correspondence between the target temperature and humidity level and the defrost level, the target defrost level can be determined conveniently and quickly, thereby quickly instructing the defrost module to defrost the blood bags in the target area based on the wind speed corresponding to the target defrost level, thereby improving the defrost efficiency of the blood bags.

[0095] In some embodiments, the above method further comprises:

[0096] Acquire the temperature and humidity data of the target area collected by the temperature and humidity detection module at each preset time interval; if the temperature and humidity data do not meet the preset temperature and humidity conditions, control the dehumidification module to dehumidify the target area until the temperature and humidity data of the target area meet the preset temperature and humidity conditions.

[0097] The description of this step can refer to the description of the corresponding steps in the above-mentioned blood bag defrosting system, which will not be repeated here. If the temperature and humidity data of the target area do not meet the preset temperature and humidity conditions, the target area is dehumidified by the dehumidification module until the temperature and humidity data of the target area meet the preset temperature and humidity conditions, thereby increasing the time for the temperature and humidity of the target area to meet the preset temperature and humidity conditions, so that the humidity of the target area is lower, which can reduce the amount of frost condensed on the surface of the blood bag. When the blood bag is detected and defrosted, the wind speed of the defrosting module for defrosting can be reduced, and the defrosting speed can be accelerated, thereby improving the defrosting efficiency of the blood bag.

[0098] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders.
