The comprehensive chemical substance management system 1 according to the present embodiment includes only a simple configuration for clearly explaining the technical idea to be proposed.

Referring to FIG. 1, the comprehensive chemical substance management system 1 includes a plurality of reagent stations 100, a management server 200, and a firefighter terminal 300.

The main operations of the comprehensive chemical substance management system 1 configured as described above are as follows.

The reagent cabinet 100 is a kind of furniture for storing reagents used in chemical, biological, and radiation experiments, and is mainly used in laboratories such as research institutes, companies, factories, and schools.

There are various types of reagents, and each type has its own characteristics, so the reagents are classified among the same characteristics and stored in the same place. In addition, according to the characteristics of the reagent, the gas generated from the reagent and the reagent are classified and stored so as not to cause a chemical reaction when mixed with each other.

That is, it is very important that the reagent cabinet 100 is configured to safely store reagents therein, and has a structure capable of minimizing suffocation, fire, and explosion accidents.

On the other hand, the reagent cabinet 100 of the present invention is configured to continuously detect individual weights of a plurality of reagent containers.

That is, the reagent cabinet 100 has a multi-stage table, and each table has a plurality of weight detectors capable of detecting the weight of the reagent container. That is, since each weight detection unit is arranged to individually measure the weight of the allocated area, the weight of each reagent container can be independently detected.

In addition, the reagent compartment 100 is provided with a scanner that automatically recognizes the identification code attached to each reagent container whenever each reagent container is brought in or taken out. In particular, the reagent compartment 100 may automatically recognize an identification code whenever a reagent container is carried in or taken out, and at the same time detect a point at which a weight change occurs, thereby grasping the internal positions of the plurality of reagent containers in real time.

For example, if a point where a weight change is detected occurs within a predetermined time after the identification code is recognized, the reagent container has been brought in. In addition, if the weight change is detected and the identification code is recognized within a predetermined time, the reagent container has been taken out.

The management server 200 wirelessly exchanges data with the reagent reservoir 100 to receive and manage the loading and unloading status, usage, expiration date, and internal location of a plurality of reagent containers in real time.

In addition, the management server 200 assigns and manages the reagent reservoir 100 with a unique ID of the reagent reservoir. In particular, the location of the building where the reagent reservoir is placed and the location of the reagent reservoir on the floor plan of the building are databaseized and managed.

The management server 200 separates and displays the location of the radiation laboratory, the biosafety laboratory, the precision safety diagnosis laboratory, and the hazardous machine on the floor plan of the building based on the material composition of the reagent container stored in the reagent chamber. The container is marked as being located within the laboratory where the reagent field is placed for a predetermined period of time,

Class 3, 4, and 5 under the Dangerous Goods Safety Management Act can be classified and labeled, the presence/absence of automated fire extinguishing facilities can be indicated, and combustible gas, auxiliary gas, and toxic gas can be classified and labeled. At this time, the management server 200 may support efficient work by transmitting the above-described information to a user terminal or a fire fighting person terminal.

For reference, the management server 200 may indicate that the reagent container carried out from the reagent reservoir is located in a laboratory in which the reagent reservoir is disposed for a predetermined period of time. That is, in many cases, researchers take out the reagent containers stored in the reagent cabinet and use them in the laboratory, so the management server 200 is assumed to be located in the laboratory for a predetermined period of time when the reagent containers are brought into the reagent cabinet and then taken out again. To indicate.

In addition, the management server may provide a material safety data sheet (MSDS) for material components of a plurality of reagent containers to a user terminal.

For reference, the Material Safety Data Sheet (MSDS) contains basic safety/health data for chemical substances (including chemical name, Chemical Abstracts Service (CAS) registration number, harmful properties, and known acute/chronic health data). It is a document for the purpose of preventing accidents caused by substances handled by organizing and subdividing the items accordingly and presenting them to workers.

In Korea, in accordance with Article 41 of the Occupational Safety and Health Act (preparation of material safety and health data, etc.), business owners who manufacture/import/use/transport/store chemical substances prepare MSDSs and keep them at the workplace. Warning signs are affixed to containers or packaging to inform them of hazards, and to provide safety and health education to workers.

That is, when a user holding a user terminal removes a reagent container from the reagent compartment 100, the management server 200 provides a Material Safety Data Sheet on the material components of the reagent container that is being carried out to the user terminal. , MSDS) is automatically transmitted to notify the user of the hazard and danger to the user who handles chemical substances, so that the user himself can protect himself and quickly respond to an unforeseen chemical accident.

2 is a block diagram of the reagent chamber 100 of FIG. 1.

Referring to FIG. 2, the reagent compartment 100 includes a scanner 101, a weight detection unit 102, a communication module 103, a temperature sensor 104, a humidity sensor 105, a harmful gas detection sensor 106 and a control unit. It is comprised of 120.

The scanner 101 is a device that recognizes an identification code attached to a reagent container. The identification code may include at least one or more of a barcode, a QR code, and an RF tag.

The weight detection unit 102 is mounted on a table of a reagent chamber and detects a point where a weight change occurs to detect the positions of the plurality of reagent containers. For example, the table of the reagent chamber is internally divided into a two-dimensional matrix arrangement, and a weight sensing unit is disposed at each point to detect the weight of a reagent bottle disposed in the corresponding area. At this time, it is assumed that a plurality of weight sensors are arranged in each weight detection unit.

On the other hand, when a reagent bottle with a large size is first placed on the table, two weight detection units may be in a state to measure the weight at the same time. In this case, when the reagent bottle is first placed in the corresponding area, the two weight detection units The size of the pre-allocated area is automatically adjusted to detect the weight of one reagent bottle.

That is, the plurality of weight sensors of the first weight detection unit and the plurality of weight sensors of the second weight detection unit do not individually measure weight, but are automatically integrated to measure the weight of one reagent bottle. In this way, the size of the two-dimensional array is variably adjusted according to the size of the reagent bottle, and the size of a pre-allocated area is adjusted so that the plurality of weight detection units can detect the weight of one reagent bottle.

The communication module 103 is provided to exchange data wirelessly with the management server 200.

It serves to control the operation of the (105) and the harmful gas detection sensor (106).

3 is a diagram showing fire fighting information provided by the management server.

3, the management server 200 of the chemical substance management system 1 is the location of the building where the fire occurred on the map, and the building when fire information is received in the building where the reagent reservoir 100 is placed. Automatically transfers the location of the reagent pond to the designated manager terminal or firefighter terminal on the floor plan of. Here, the fire occurrence information is managed in a separate fire fighting system and transmitted to the management server 200 in real time.

In addition, when the information on the occurrence of fire is received in the building in which the reagent reservoir is placed, the management server 200 maintains the location of the building where the fire occurred on the map, the location of the reagent reservoir on the floor plan of the building, and the loading state in the reagent reservoir. The material components of a plurality of reagent containers are transmitted to the designated manager terminal or the fire department terminal. At this time, the management server 200 considers that the reagent container carried out from the reagent reservoir is located in the laboratory in which the reagent reservoir is disposed for a predetermined period of time, and transmits the material components of the discharged reagent container to the manager terminal or the fire department terminal. That is, in many cases, researchers take out the reagent containers stored in the reagent cabinet and use them in the laboratory, so the management server 200 is assumed to be located in the laboratory for a predetermined period of time when the reagent containers are brought into the reagent cabinet and then taken out again. To indicate.

In addition, when the information on the occurrence of fire is received in the building in which the reagent reservoir is placed, the management server 200 maintains the location of the building where the fire occurred on the map, the location of the reagent reservoir on the floor plan of the building, and the loading state in the reagent reservoir. In addition to transmitting the material components of a plurality of reagent containers to the designated manager terminal or the fire department terminal, if a substance that reacts chemically with water is stored in the reagent chamber, the storage amount of substances that react chemically with water and the floor plan of the building by the fire department terminal It can help to efficiently process fire suppression by transmitting the location of the reagent chamber on the screen.

For example, alkali metal is an expression that refers to all chemical elements other than hydrogen in Group 1 of the periodic table. Lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs) , Francium (Fr) belongs to this chemical family. It is very reactive and reacts quickly when it encounters oxygen, water, or halogen elements.

That is, since the reactivity is very excellent, when water comes into contact, the reaction occurs at a rapid rate and reacts explosively. Therefore, the fire must be extinguished with limited use of water around the reagent chamber where such substances are stored.

The management server 200 may determine the amount of change in temperature and humidity of all reagent plants in real time, and then calculate the degree of risk based on the amount of change.

In particular, when the fire occurrence information is received, the management server 200 may calculate the risk of destruction based on the temperature change amount and the humidity change amount of all reagent plants. This information is transmitted to the manager terminal and the firefighting personnel terminal so that the fire propagation path can be indirectly transmitted.

The management server 200 can receive real-time information on the operation of the air conditioner of the building where the fire has occurred from the firefighting system. Based on the operation information of the air conditioner, the hazardous substance is predicted when a fire occurs at the location of the reagent room on the floor plan of the building. The diffusion path can be simulated and provided.

In addition, when multiple reagent sites are damaged due to a fire, the predicted diffusion path of hazardous substances is simulated, but information indicating the predicted points where chemical reactions can occur due to leaking substances can be provided on the floor plan of the building. .

In addition, after simulating the predicted points where chemical reactions can occur due to the leaked substances and the expected diffusion path of hazardous substances, the neutralizing agent that can be used based on the operation information of the air conditioner-the neutralizing agent of the leaked substance-and each neutralizing agent It is possible to provide information that displays the optimal point for putting in on the floor plan of the building.

For reference, an identification code such as a barcode or QR code is attached to the reagent container. This identification code is not an identification code given by the chemical substance management system (1) to the reagent container, but is defined as an identification code attached by the company that manufactured/sold the reagent container.

Therefore, the reagent storage 100 may perform a process of generating an identification code for managing the reagent container by itself.

That is, the reagent compartment 100 generates a final identification code by itself by combining the identification code attached to each reagent container and a location code corresponding to the internal location of each reagent container. In this case, when a plurality of reagent reservoirs 100 are provided, a final identification code may be generated by combining all of the reagent reservoir's unique ID, location code, and identification code. In addition, it will be possible to generate a final identification code by combining all of the reagent reservoir's unique ID, location code, identification code, and initial weight value of the reagent container.

For reference, it is common for the weight of the reagent container to decrease when the carrying-out state is repeated after the reagent container is initially loaded. Therefore, when the weight of the reagent container is increased when the reagent container is switched from the carrying-out state to the carrying-in state, the reagent container 100 automatically transmits a warning message to the user terminal so that it is possible to check whether the reagent container has deviated from the initially set internal position.

In this way, the comprehensive chemical management system (1) creates the final identification code by combining the location code corresponding to the internal location of the reagent container and the identification code attached to each reagent container, thereby identifying the existing identification attached to each reagent container. There is an advantage of being able to use the code as it is.

The chemical substance management system according to an embodiment of the present invention includes a storage amount of a substance chemically reacting with water by a firefighting person's terminal when a fire occurrence information is received in a building in which a reagent reservoir is arranged, the location of the reagent reservoir on the floor plan of the building, and The types of dangerous substances that are stored or taken out of the reagent room and located in the laboratory can be transmitted.

Therefore, firefighting personnel can try to extinguish fires effectively by using limited water or neutralizing substances after grasping the characteristics of dangerous substances.

As such, those skilled in the art to which the present invention pertains will be able to understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential features thereof. Therefore, the embodiments described above are illustrative in all respects and should be understood as non-limiting. The scope of the present invention is indicated by the claims to be described later rather than the detailed description, and all changes or modified forms derived from the meaning and scope of the claims and their equivalent concepts should be construed as being included in the scope of the present invention. do.
