1 to 3, the smart factory system based on group operation of IOT and non-IOT modules for industrial processes using the zone master of the present invention is a database for system management, data storage and processing, monitoring and A server (1) that can transmit and receive information by being connected to an external safety control network, etc., which is connected to the server (1) and grouped by region or object type to identify the information transmitted from the object terminal (3), and then to the server (1) It consists of a zone master (2) for transmission to the mobile station, and an object terminal (3) installed in a target object to be managed, respectively, for the operation of IOT modules and non-IOT modules to obtain information.

At this time, a single or a plurality of zone masters 2 as described above may be applied. For example, through communication with an object terminal 3 installed in an IOT module or non-IOT module installed in a single factory or a single region, each zone Alternatively, it can be grouped according to the type of input information and transmitted to the server 1, or a plurality of zone masters 2 can be provided in a plurality of regions for each region and type of input information, and a network can be formed and managed. .

In addition, through grouping according to the information conditions set by the user through the zone master 2 and the release of grouping, it is possible to strengthen security maintenance to prevent information leakage due to external accessors or external factors.

Among the configurations of the system of the present invention as described above, the server 1 includes a central processing unit 11 , a communication terminal unit 12 , and a data memory unit 13 .

In addition, the server 1 is configured to further include an image processing unit 14 .

The central processing unit 11 is in charge of system operation and management and processing of input information. The double information processing refers to processing of data values input through the zone master 2, and the condition value set by the user. A conditional processing function that compares and judges object information, which is a data value input through the zone master (2), is possible, and when the data corresponding to the processing method set by the user is pressed, the corresponding processing method is provided. .

Here, the condition processing function determines the status of the IOT module or non-IOT module of the object terminal 3 connected to the zone master 2 by determining if the data input from the object corresponds to the range of the data value set by the user. will be judged

For example, the input data becomes information such as temperature, pressure, flow rate, and liquid level, and the temperature section, pressure section, flow rate section, and liquid level section set by the user as information grasped through a sensor provided in each target object. It refers to the case where the value of the information entered in .

In addition, if the input data corresponds to the conditions set by the user, the event status is stored in the database, or the administrator is notified or the external safety control network is notified.

In addition, in case of an emergency, the remote control of the device is performed by transmitting a control command for each object, such as an industrial process device.

The communication terminal unit 12 performs communication with a single or a plurality of zone masters 2 and enables communication with a user terminal for management and an external safety comprehensive control network through an external computer network.

In this case, the communication terminal unit 12 uses an internal computer network through a dedicated line when it is necessary to maintain extreme security, and otherwise enables communication through an external computer network.

The data memory unit 13 stores information input from the target object and converts it into a DB. Identification information on the zone master 2, identification information of the object terminal 3 connected to each zone master 2, and The entered information is saved.

As a method of storing information as described above, information about the state of the object, which is information input from the object terminal 3, that is, information such as temperature, pressure, flow rate, and level, is based on the identification information of the object terminal 3 to save it.

At this time, if the state of the information input from the object terminal 3 is a normal section rather than a section set by the user, only the status information is stored in the data memory unit 13, and the state of the information input from the object terminal 3 If the user belongs to the event section set by the user, the event occurrence is separately stored together with the identification information, so that the user does not read a large amount of data one by one, but only the section where the event occurred and the data of the object terminal 3 where the event occurred to be able to browse.

The image processing unit 14 processes image information based on multiple resolutions. When a network is formed through a plurality of zone masters 2 , the overall network situation is expressed in the primary image frame, and an event occurs or a user The second image frame is expressed by intensively magnifying the video of the zone master (2) you want to view, so that the overall operation status of the plurality of zone masters (2) and the status of the zone master (2) can be recognized at a glance. .

Here, if there is an abnormality in the object terminal 3 managed by the zone master 2 or if the user wants to view it, a tertiary image frame can be further added, and the tertiary image includes the zone master's corresponding device. Information about information and the image of the main device are enlarged to provide a multi-stage, multi-resolution image.

At this time, as described above, the secondary image frame and the tertiary image frame intensively enlarge the image part desired by the user or the target object such as the zone master 2 or the object terminal 3 among the images of the primary image frame. By applying high-quality images, it is possible to selectively apply high-capacity data according to image processing and transmission to improve processing and transmission speed, and to minimize additional facilities for data storage.

Although the bottom-up multi-resolution image processing method has been described as an example as described above, it should be noted that the top-down multi-resolution image processing method can also be applied.

To provide such an image processing method, if the number of zone masters 2 and object terminals 3 to be monitored by the user increases and becomes in the form of large-scale big data, the time and effort invested by the user to manage it is to minimize

In addition, the image processing unit 14 processes multiple resolutions and multiple image frames for displaying multiple resolution images on one screen, such as a primary image frame to a tertiary image frame, when an emergency situation occurs, when an emergency situation occurs, Check the optimized communication line for rapid communication with the target object, request the central processing unit 11 to secure a priority line for this, and communicate with the target object in an emergency situation through the communication terminal unit 12 to secure the optimal communication line of

In addition, when an emergency situation of the target object is detected, it is displayed by the image processing unit 14 and at the same time notifies the central processing unit 11 of this, so that the situation of other target objects belonging to the same group as the target object for which the emergency situation is detected is automatically displayed. to be able to check with

The multi-resolution image processing method may be manually set by the user, but when an event occurs, the central processing unit 11 determines it and automatically processes and displays the image on the screen.

The zone master 2 connected to the server 1 manages the power supplied to the communication terminal 21 and the zone master 2 that communicate with the server 1 and the IOT module and non-IOT module. Consists of a power management unit (22).

Here, as described above, the analog 8-point and digital 16-point nodes are for example only, and are not limited thereto, and the number of nodes may vary depending on the situation.

In addition, in the case of the analog terminal 21a, power line communication, that is, a PLC (Power Line Communication) device is applied, and in the case of the digital connection terminal 21b, it is applied to a device equipped with an IOT function.

IOT module and non-IOT module can be matched 1:1 to connect to the node such as above, and the IOT module and non-IOT module can be devices and devices in the production process, which are respective objects that the user needs to monitor. .

In addition, the power management unit 22 is to control the regular power and the emergency power, and is driven by receiving input from the regular power in normal times, and converts the power to the emergency power in case of an emergency when power is not supplied.

To this end, a regular power management module 22a for managing the constant power and an emergency power management module 22b for managing the emergency power are provided.

The reason for controlling the regular power and emergency power in this way is that information generated from target objects such as process machines or storage facilities, which are target objects located in the jurisdiction of the zone master 2, must be acquired regardless of external conditions.

For example, if monitoring and management of factors such as temperature and pressure are important, it is to prevent the occurrence of dangerous situations such as explosions or spills by failing to detect changes in factors such as temperature and pressure in emergency situations.

Here, the emergency power may be a separate emergency generator provided outside or a power storage device provided inside the zone master 2, and the power storage device provided inside the zone master 2 may be a conventional rechargeable battery or the like. can be

This is to store some of the regular power as emergency power through the emergency power management module 22b when the regular power is supplied, and convert it to emergency power when the regular power supply is stopped to maintain the operation of the zone master 2 will be.

The object terminal 3 connected to the zone master 2 and installed on a process machine as a target object to obtain information may be a sensor unit having a communication function.

With such a sensor unit, anything that can sense temperature, pressure, flow rate, liquid level, etc. is possible. For example, any field information that needs monitoring other than temperature, pressure, flow rate and liquid level is possible.

In addition, information of peripheral devices other than the sensor unit is additionally acquired and information can be processed therefrom. For example, image information of a CCTV system for acquiring image information between processes can be acquired.

For example, it is possible to check the safety state of the producer and the on-site production process, and the image information of the situation in which an event occurs is compared with the usual image information set by the user, and the manager or the user is notified of this.

Here, for the part related to the producer's work safety, it is judged whether there is an abnormality in the producer's working movement or the producer's face recognition, and drowsiness is determined by using deep learning techniques to determine the features of the producer's face, especially the eyes It is determined whether or not the producer is drowsy while working, so that it can be notified to the manager or a terminal such as the producer's mobile phone.

In addition to the object terminal (3), the zone master (2) acquires information from a peripheral device and transmits it to the server (1), and the server (1) that receives it processes and analyzes the information based on such information to analyze safety accidents during work will prevent from occurring.

Even at this time, it is possible to express the multi-resolution image on the management screen through the image processing unit 14 .
