Chemical management site management system 100 of the present invention can improve the accuracy and safety accidents in the management of the workplace by automating the entire factory to store and manage chemical factories or chemicals, environmental, industrial hygiene Field, occupational safety and health field, and the like.

First, a tag containing information on the chemical and a sensor for recognizing opening and closing of the lid of the container are attached to the container of the chemical.

The operation of step 210 is performed by the tag mounting unit 110 of the management system 100.

The tag mounting unit 110 attaches and outputs a tag containing information on a chemical to a container (not shown) in which the chemical is contained. The tag contains information about the chemical being received. That is, necessary information such as material information such as name and property of chemical substance, arrival time, shipping time, and movement information such as location of received and stored location are stored in the tag in advance.

The container containing the chemicals received is received into the tag mounting unit 110 according to a predetermined order and time, and the tag mounting unit 110 automatically attaches the tag to the container. Since the operation of attaching the tag to the container and the principle thereof by the tag mounting unit 110 can be understood by those skilled in the art, a detailed description of the structure or operation of the tag mounting unit 110 will be omitted.

In addition, the tag mounting portion 110 is also attached to the lid opening and closing recognition sensor to be described later in the container. Lid opening and closing sensor is a sensor that determines whether the lid of the container containing the chemical is open or closed. The lid opening and closing sensor may be implemented to generate a signal when the lid is opened using a position sensor or an infrared sensor, and can be easily developed by those skilled in the art.

When the container is moved, the movement of the container is checked and wireless receipt of the container to the workplace is confirmed at step 220.

Moving check and receipt of the container, delivery confirmation is performed by a plurality of readers 120 arranged in the workplace. That is, when the container is moved, the plurality of readers 120 checks the movement of the container and wirelessly confirms receipt and release of the container to the workplace.

The readers 120 are controlled by the controller 130 and are attached to various places in the workplace. Readers 120 may be mounted on the inner wall of the workplace, or stand on a separate reader frame. The containers tagged by the readers 120 are checked from the moment of arrival at the workplace by the wireless communication between the tag and the reader, from the moment of arrival at the workplace to the movement within the workplace and out of the workplace.

The readers 120 receive the information stored in the tag and transmit it to the control unit 130, and the manager can check the situation of the container containing the chemicals using the control unit 130. The controller 130 collects and manages movement information and material information of the containers output from the readers 120.

In this case, the monitors 140 are controlled by the control unit 130 and are installed at predetermined spaces in the workplace to provide hazard risk information to the workers. That is, the monitors 140 are installed one per prominent place and an enclosed space of the worker, and display the information transmitted by the controller 130. Since the control unit 130 knows where the container containing the chemicals is located in the current workplace, the hazardous risk information is displayed on the monitor near the container according to the information of the chemical contained in the nearby container. Workers can be notified of the risk or warn them of the level of risk.

Such hazard information includes Material Safty Data Sheets (MSDS) and hazard warning labels. That is, the hazard information includes MSDS (Material Safety Data Sheet) and hazard warning signs so that workers can check the nature or degree of danger of chemicals in the vicinity through the monitor. Is operated in a touch screen manner so that the worker can obtain the necessary information by touching.

Therefore, workers can be provided with the most optimized training programs for the process (online training on hazard hazard education, handling and management of harmful substances, wearing protective equipment, etc.).

The database 150 is controlled by the controller 130, stores the hazard information, provides the monitor 140, and updates the hazard information. That is, the manager can continually change the hazard information or other information required by the worker by updating the database 150.

Such devices enable smooth and automatic reduction of industrial accidents and process control in the workplaces dealing with chemicals.

The control unit 130 determines whether a lid of an arbitrary container is opened in response to the output signal of the sensor (step 230). If it is determined that the lid is opened, the controller 130 may determine from the material information and movement information of the opened container. Determine the type of chemicals in the space in which the container is placed (step 240) and calculate the concentration of chemicals that may appear in the space when the chemical is spread in the space in which the container is placed (step 250); The calculated time is displayed on a corresponding monitor or an alarm sounds when there is a possibility that the worker is exposed to a certain management concentration level or discharged to the outside air (step 260).

For the operation of the control unit 130, the tag mounting unit 110 attaches to the container a sensor for recognizing the opening and closing of the lid of the container in addition to the attachment of the tag. In addition, the readers 120 receive the output signal of the sensor and transmits it to the controller 130 along with the movement information and the material information.

When the lid of the container containing the chemical is opened, the sensor that recognizes the opening and closing of the lid recognizes it and transmits an output signal. Then, the reader in the vicinity of the container recognizes the output signal of the sensor as well as the tag information and transmits the output signal along with the movement information and material information contained in the tag to the controller 130.

The operation of recognizing the output signal of the sensor may be implemented by attaching the receiver to the reader and connecting the transmitter (not shown) of the reader to the receiver. Such implementations will be omitted by those skilled in the art and will not be described in detail.

When the controller 130 confirms that the lid of an arbitrary container is opened from the sensor's output signal, the controller 130 determines the type of space and internal chemicals in which the container is placed from the material information and movement information of the opened container. Judge, calculate the concentration of the chemical in the space where the container is placed and allow workers to be aware of it by displaying the calculated concentration on the corresponding monitor. In addition, when the predetermined concentration level exceeds a predetermined level, an alarm sounds so that the workplace manager can manage it. The predetermined management concentration may be determined in advance according to the type and nature of the material and the size of the space, and may be stored in the controller 130.

In addition, sensors for measuring the concentration of the chemicals in the space where the chemicals are spread may be separately mounted throughout the workplace to determine whether or not to approach or above the management concentration.

The controller 130 stores an equation for calculating the concentration required to reach a dangerous level according to the type of substance contained in the container from the substance information. The controller 130 calculates and displays the concentration on the monitor.
