Laboratory hazardous chemical reagent warehouse-in and warehouse-out intelligent management and control system and method

Abstract

The invention discloses a laboratory hazardous chemical reagent warehouse-in and warehouse-out intelligent management and control system and method. The system comprises a fingerprint identification electronic device, a hazardous chemical reagent quantity automatic identification device, a control computer and a management computer. The fingerprint identification electronic device comprises a fingerprint identifier and an electronic lock, the fingerprint identifier is used for identifying and confirming the identity of laboratory management personnel, the electronic lock is used for opening / closing the laboratory door, and the management computer is used for recording the time when the electronic lock opens / closes the laboratory door; the hazardous chemical substance chemical reagent quantity automatic identification device is used for automatically judging the types and quantity of hazardous chemical substance chemical reagents and comprises a power supply, a gravity sensor and a communication module which are connected in sequence, the communication module is connected with a control computer through an RS485-to-Ethernet server, and the control computer is connected with a management computer. According to the invention, the gravity sensor is used for judging the inventory of hazardous chemical reagents, so that the management and control of the hazardous chemical reagents inthe laboratory in and out of the warehouse are realized.

Description

technical field [0001] The invention relates to the management of laboratory chemical reagents entering and exiting the warehouse, and more specifically, to an intelligent management and control system and control method for laboratory hazardous chemical reagents entering and exiting the warehouse. Background technique [0002] As stated in Article 3 of Chapter 1 of the "Regulations on the Safety Management of Hazardous Chemicals", the so-called hazardous chemicals refer to highly toxic chemicals that are poisonous, corrosive, explosive, flammable, and combustion-supporting, and are harmful to the human body, facilities, and the environment. products and other chemicals. [0003] Hazardous chemicals include explosives, compressed gases and liquefied gases, flammable liquids, flammable solids, spontaneous combustion and flammable materials when wet, oxidants and organic peroxides, poisonous and corrosive products, etc. According to my country's currently published regulation...

AI Technical Summary

Problems solved by technology

[0007] First, in this patent, "weighing the current remaining weight of each chemical reagent and calculating the current consumption of each chemical reagent" is a good method in theory, when there are many in the actual application of the laboratory The big question is, first of all, "weighing each chemical reagent". When the laboratory personnel receive a certain chemical reagent, how does the smart scale associate with the cloud server? What kind of reagents to use, this patent does not give a method; secondly, laboratory hazardous chemical reagents are usually packaged in bottles, although the current remaining amount can be obtained through the differential method, but because the container itself of chemical reagents has weight, and the laboratory The Hazardous Chemicals Reagent Management Regulations clarify that when the chemical reagents are used up, the empty reagent bottles need to be cleaned up in time. bottle of 500ml sulfuric acid), according to this method, the consumption of hazardous chemicals chemical reagents will be calculated, which obviously cannot meet the requirement of the patent that "the current consumption of each chemical reagent can be calculated by subtracting the current remaining weight from the weight of the reagent recorded last time" requirements, and cannot be implemented in the laboratory

[0008] Second, this patent only describes the use and operation plan of part of the out-of-warehouse collection and use, but does not give a control plan for the in-warehouse operation
