Verification and abnormal moving alarming system for liquid nitrogen storage tank

Abstract

The invention discloses a verification and abnormal moving alarming system for a liquid nitrogen storage tank, and provides a system for verifying identity of a user moving the storage tank and alarming for abnormal moving of a storage tank body. The verification and abnormal moving alarming system comprises a vibration sensor, a radio frequency verification module, a user key module, a center control module, an alarming module and a service platform, wherein the vibration sensor is used for sensing vibration information of the storage tank; the radio frequency verification module adopts an RFID reading device and reads user information; the user key module adopts an RFID electric label and is provided with user information; the center control module controls the working state of the alarming module according to a verification result of the radio frequency verification module; the alarming module is used for generating alarming information and sensing the alarming information to the service platform; and the service platform sends the alarming information to the user.

Description

Background technique [0001] Liquid Nitrogen: Nitrogen gas in liquid form. It is inert, colorless, odorless, non-corrosive, non-flammable, and has an extremely low temperature. Nitrogen makes up the majority of the atmosphere (78.03% by volume, 75.5% by weight). Nitrogen is inert and does not support combustion. [0002] Liquid nitrogen is currently widely used, and is widely used in rapid freezing, freezing anesthesia, food refrigeration, metallurgical industry, washing and other fields, but because of its own properties, liquid nitrogen has a melting point of -210°C, a boiling point of -195.8°C, and a critical temperature : -147°C, critical pressure: 3.39Mpa. and other factors, it is necessary to monitor its storage status. At the same time, with the widespread use of liquid nitrogen storage tanks in various fields, portable liquid nitrogen storage tanks are popular in enterprises because of their portability and mobility. The movement of the liquid nitrogen storage tank ...

and other factors, it is necessary to monitor its storage status. At the same time, with the widespread use of liquid nitrogen storage tanks in various fields, portable liquid nitrogen storage tanks are popular in enterprises because of their portability and mobility. The movement of the liquid nitrogen storage tank can be realized quickly and conveniently at any time. The traditional liquid nitrogen storage tank lacks management. In the production workshop, employees have the problem of random use and placement, which brings inconvenience to the management of the liquid nitrogen storage tank, and portable storage The tank body is easy to carry, but it also has the problem of being easily stolen. The traditional method is to directly install a GPS device on the storage tank body, but the GPS device is easily damaged. If it is stolen, it is powerless if it is not discovered in time
