Description

Technical Field

[0001] The present invention relates to the technical field of sample preservation, and in particular to an intelligent early warning system for facilitating sample preservation. Background Art

[0002] According to the definition of the Organization for Economic Cooperation and Development (OECD), a biobank is a biological application system that centrally stores various human biological materials for clinical treatment of diseases and life science research.

[0003] A biobank, also known as a biobank or sample resource library, refers to the standardized collection, processing, storage and application of samples of biological macromolecules, cells, body fluids, tissues and organs of healthy and diseased organisms, as well as clinical, pathological, treatment, follow-up, informed consent and other information related to these biological samples and their quality control, information management and application systems. It is a comprehensive resource that integrates biological sample entities, biological information, sample phenotypic data and sample research information.

[0004] In a biobank, there are usually dozens to hundreds of ultra-low temperature refrigerators running at the same time, which are responsible for storing very important biological samples. However, current monitoring methods have some shortcomings. The traditional method relies on installing a third-party sensor in the refrigerator. When the sensor detects that the temperature is out of the set range (for example, -80℃±10℃), an alarm will be sent to the monitoring system. But this method has two main problems.

[0005] First, when the sensor sounds an alarm, the temperature is often out of the safe range, which means that the sample may have been damaged. If the alarm occurs at night or on holidays, maintenance personnel cannot respond in time, and the risk of sample loss is greater. In addition, ultra-low temperature refrigerators usually use a top-down direct cooling method, and sensors are often only arranged in one position in the refrigerator. For example, if the sensor is located in the center of the refrigerator, and the refrigeration system fails and the temperature in the lower part gradually rises, the temperature of other parts may have already exceeded the safe range before the sensor detects the abnormality.

[0006] Although the monitoring accuracy can be improved by adding multiple sensors, this is not an ideal solution. First, the increase in sensors will take up valuable storage space in the refrigerator and affect the storage capacity of the samples. Second, the cost of wireless transmission sensors in low-temperature environments is very high. Using a large number of them will significantly increase the cost of the overall system, which does not meet the requirements of economical and practical use.

[0007] Therefore, an intelligent early warning system that is convenient for sample preservation is needed to solve the above problems. Summary of the invention

[0008] The purpose of the present invention is to provide an intelligent early warning system that is convenient for sample preservation and solves the above-mentioned technical problems.

[0009] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an intelligent early warning system for facilitating sample preservation, comprising an ultra-low temperature refrigerator, the ultra-low temperature refrigerator comprising a compressor and a door, a plurality of storage plates fixedly installed inside the ultra-low temperature refrigerator, a plurality of sample cells fixedly arranged between every two of the storage plates, a sensor fixedly arranged on the surface of the storage plate, the sensor electrically connected to a controller, and the controller electrically connected to the ultra-low temperature refrigerator.

[0010] Preferably, the plurality of sample cells are arranged equidistantly.

[0011] Preferably, the temperature inside the ultra-low temperature refrigerator detected by the sensor is Ta, the set temperature inside the ultra-low temperature refrigerator is Ts, and the controller determines the value of Ta. When the value of Ta is greater than Ts, the controller sends an instruction to the ultra-low temperature refrigerator, and the ultra-low temperature refrigerator controls the compressor to start refrigeration. When the value of Ta is less than or equal to Ts, the controller sends an instruction to the ultra-low temperature refrigerator, and the ultra-low temperature refrigerator controls the compressor to shut down.

[0012] Compared with the related art, the intelligent early warning system for facilitating sample preservation provided by the present invention has the following beneficial effects:

[0013] The present invention provides an intelligent early warning system for facilitating sample preservation. During the normal operation of an ultra-low temperature refrigerator, a sensor monitors the temperature inside the ultra-low temperature refrigerator in real time, and the sensor transmits the monitored temperature to a controller, and the controller sends instructions to control the start and stop of a compressor of the ultra-low temperature refrigerator, thereby ensuring that the temperature inside the ultra-low temperature refrigerator remains constant, so as to facilitate the proper preservation of samples placed in sample cells; the controller analyzes daily operation data of the ultra-low temperature refrigerator to establish a data model, and when it is detected that the data inside the ultra-low temperature refrigerator deviates from the data model value, even if the temperature inside the ultra-low temperature refrigerator has not exceeded a set range, an early warning can be issued in advance, so as to facilitate the preservation of samples, which can not only reduce costs and reduce the use of sensors, but also remind maintenance personnel before an accident occurs, so as to better protect the safety of samples.
