A system and application method for automatic monitoring and intelligent early warning of liquid nitrogen tank weight

Abstract

The present invention provides a liquid nitrogen tank weight automatic monitoring and intelligent early warning system and its use. The system includes: N base sensors, a controller, and an early warning device; the base sensor obtains the monitoring time point and the event type corresponding to the time point, The weight data of the liquid nitrogen tank corresponding to the time point is transmitted to the controller; the early warning device receives the data sent by the controller, and analyzes the data of the liquid nitrogen tank to determine that the distance of the liquid nitrogen content in the liquid nitrogen tank reaches the safety line, warning The time required for the line, whether to generate an early warning message. According to the solution of the present invention, by regularly weighing and calculating the daily consumption of liquid nitrogen in the experimental environment, and then calculating the time point when liquid nitrogen needs to be added and purchased, the purpose of automatic monitoring and intelligent early warning can be achieved. The uncertainty and instability of manual monitoring are avoided.

Description

technical field [0001] The invention relates to the field of data information management, in particular to a liquid nitrogen tank weight automatic monitoring and intelligent early warning system and use device. Background technique [0002] Liquid nitrogen is mainly used as a refrigerant in biological laboratories and medicine to rapidly freeze biological tissues or experimental samples to prevent tissue or samples from changing or decaying. Liquid nitrogen is usually stored indoors by a liquid nitrogen tank. Biological tissues or experimental samples stored in liquid nitrogen tanks are often extremely rare and precious, and liquid nitrogen is extremely volatile during use or storage in the laboratory. Once the liquid nitrogen volatilizes and is not replenished in time, The increase in temperature will lead to changes in biological tissues or experimental samples, which will cause irreparable damage. Therefore, scientific monitoring and management of liquid nitrogen is req...

Problems solved by technology

[0006] In order to solve the above technical problems, the present invention proposes a liquid nitrogen tank weight automatic monitoring and intelligent early warning system and its use method. Manual management of liquid nitrogen cannot waste manpower and liquid nitrogen, or cause damage to the preservation of biological tissues and experimental samples; the technical problem that the time required for the liquid nitrogen content in the liquid nitrogen tank to reach the safety line and the warning line cannot be effectively calculated
