1 is a system diagram showing a production facility management system according to an embodiment of the present invention.

Referring to FIG. 1, a production facility management system according to an exemplary embodiment of the present invention may include a plurality of sensor nodes 400, a sensor gateway device 500, a server 100, and a user terminal 200.

Specifically, the sensor node 400 transmits the sensing information collected by the sensors mounted in each process facility to the sensor gateway device 500. Sensor node 400 may be an individual sensor or a collection of sensors. In addition, the sensor node 400 may be any one of a counter sensor, a temperature sensor, a pressure sensor, or a sensor assembly including the same.

For example, the counter sensor is a sensor that counts numbers by using an infrared sensor, an optical sensor, a pressure sensor, or the like. The counter sensor may collect production information produced by each process facility 300. In this case, the counter sensor may be attached to the device side, the bottom surface or the top surface of the process equipment (300). In the case where the counter sensor is an infrared sensor or an optical sensor, the counter sensor is preferably attached to the side of the apparatus of the process facility 300.

The temperature sensor may be installed in the process facility 300 to measure the temperature of the process material or the temperature of the inner surface of the work part.

The pressure sensor may measure the pressure during the process operation of the process facility 300. The pressure sensor may be measured in the process facility 300, or may be installed at a compression cylinder or a hydraulic device that performs a compression operation of the process facility.

Here, when producing a processed product by using a plurality of processes sequentially, the hydraulic pressure flowing into each process facility may be measured using one pressure sensor.

In addition, the pressure sensor may be provided in the HMI mounted to each process facility 300 to measure the pressure. The HMI is an interface between the operator and the process equipment, and can be used to implement a touch screen of the process equipment.

The sensor gateway device 500 may collect signals input from the plurality of sensor nodes 400 and transmit them to the server 100.

The sensor gateway device 500 may convert a signal input from each sensor of the sensor node 400 installed in each process facility 300 in real time and transmit the converted signal to the server 100. That is, since the signals input from the sensor node 400 are input as analog signals, the signals may be converted into digital signals, coded, and transmitted to the server 100.

The sensor gateway device 500 and the sensor node 400 may be connected through a wired or wireless network. The sensor gateway device 500 and the server 100 may also be connected through a wired or wireless network.

For example, the server 100 may statistically analyze the hourly production, daily production, monthly production, and annual production information using the signals generated by the count sensors and provide the statistical information to the user terminal 200.

In addition, the server 100 may monitor the failure or operation of each process equipment through the signals input from the temperature sensor and the pressure sensor, and the communication signal of the power line communication (PLC).

For example, the server 100 receives the temperature of the material or the working surface temperature of the process equipment through a signal input from the temperature sensor, and determines that the received temperature is out of the set value as a failure or an accident to the user terminal 200. Can transmit

In addition, the server 100 may be determined as a failure or an accident when the pressure deviates from the set value through a signal transmitted from a pressure sensor for measuring the hydraulic pressure of the plurality of process equipment and transmits it to the user terminal 200.

In addition, the server 100 may determine the operation of each process equipment through the signal transmitted from the pressure sensor provided in the HMI. For example, when a pressure is sensed in the HMI, but the operation of the factory equipment is not performed, an abnormality of the HMI or an abnormality of the process equipment may be detected and transmitted to the user terminal 200.

In addition, the server 100 may determine whether there is an abnormality of each process equipment through a communication signal transmitted through the PLC. If communication signal is not transmitted through PLC, abnormality of process equipment can be detected.

By managing it, you can check the status of the process equipment and perform production control.

Meanwhile, the server 100 may predict an optimized schedule for a work schedule for each process through the sensing signals.

In order to predict the optimized schedule, the server 100 may predict the maximum daily output in consideration of the amount of production at each process facility per hour, the daily operating time of each process facility, the movement time per process, and the like. In this case, the server 100 may predict the maximum yield when there is no failure, and change the predicted maximum yield when a failure occurs.

The server 100 may change the maximum production amount by calculating a production reduction amount due to the failure when a failure occurs in any one of the respective process facilities. The server 100 may calculate the repair time or the replacement time of the process equipment in which the failure occurs based on the accumulated information, and may reset the maximum production amount based on the calculated result.

The server 100 may store the generated maximum yield information for each time, and transmit the maximum yield information at the request of the user terminal 200.

In addition, the hall sensor for measuring each component, the temperature sensor installed for each zone, and the like are shown in the apparatus having display means such as the display unit 540 of the sensor gateway device 500 or the user terminal 200 which will be described later. It can be marked together so that the details of the abnormalities of the equipment can be checked immediately, and the worker repairing the equipment can respond more quickly.

4 is a block diagram showing a sensor gateway device of the production facility management system shown in FIG.

Referring to FIG. 4, the sensor gateway device 500 may include a sensor interface unit 510, a communication unit 520, a control unit 530, a display unit 540, and a user interface unit 550.

In detail, the sensor interface unit 510 may include a wired or wireless communication interface connected to a plurality of sensors of the sensor node as an interface for communication connection with the sensor node (400 of FIG. 1).

In an embodiment of the present invention, a serial communication module such as RS-232, RS-485, or a CAN communication module may be used to connect the sensor node.

The display unit 540 may display the signal input from the sensor node as an indicator that can be checked by the user. The display unit 540 may be installed on the front of the sensor gateway device 500, and may use a display device such as an LCD.

The communication unit 520 may include a communication interface between the sensor gateway device 500 and the server 100. The communication unit 520 may be provided with a wireless communication module or a wired communication module, and in the embodiment of the present invention, various short range communication modules such as a Zigbee communication module, a Wi-fi communication module, and a Bluetooth communication module may be used.

The user interface unit 550 is installed outside the sensor gateway device 500 so as to operate the display unit 540 by a user's input. For example, the user may manipulate the user interface 550 to display the information measured by the sensor node on the display 540.

The controller 530 may convert the signals input from the sensor nodes through the sensor interface unit 510 into digital signals and provide them to the communication unit 520. The controller 530 may be a 32-bit DSP controller. The controller 530 may transmit the signal collected by the sensor node in real time to the server 100 through the communication unit 520.

In this case, the controller 530 may divide the signals input from the plurality of sensors for each sensor and transmit them to the communication unit 520. That is, the control unit 530 converts the measurement information such as the number, status information, count information, pressure, temperature, etc. of the sensor into a set format so that the signals input from the plurality of sensors can be later distinguished from the server, and communicated with the communication unit 520. I can deliver it.

As described above, the sensor gateway device 500 may transmit sensor information collected from the sensor node to the server 100 in real time using each component.

In addition, the control unit 530, when producing a processed product by using a plurality of process equipment in sequence, by comparing the work speed, work amount, etc. for each equipment through a counter sensor, work speed and work amount so that work delay does not occur By adjusting the product, it is possible to produce an optimal product in terms of the quality and quantity of the product.

For example, if the raw material of the product is melted in the first process and the second process, and the product is completed by forming and cooling in the third process and the fourth process, the working speed of the first process and the second process is It should be similar or matched to facilitate the work in the third process and the fourth process, and there is no quality imbalance caused by natural cooling of the raw material melted in the first process or the second process. By adjusting the work speed and the work amount by comparing the installation work speed, the work amount, etc. of the first to fourth process through it can be made to produce a homogeneous product to match the work speed of the first process and the second process.

In this case, the measurement of the working speed and the amount of work is not limited, and various algorithms may be applied. For example, a method of measuring the required time by calculating the time detected by one counter sensor to the time detected by the counter sensor again.

In addition, the control unit 530, when the individual equipment is formed so that a plurality of process equipment to produce the same item, by efficiently adjusting the work speed and the amount of work by measuring the conditions such as aging, usage or work speed of each equipment Work efficiency can be maximized.

For example, if the first facility is aging or the usage is high and the work speed becomes lower than the reference value, the control unit 530 determines whether it is better to continue the work through the first facility or transfer the work to another facility. And efficiency can be calculated. In this case, if it is determined that the use of the first facility is effective, the control unit 530 continues to perform the operation. If it is determined to be inefficient, the control unit 530 operates at all or part of the second to fourth facilities. The volume can be increased to replace the workload of the first plant.

This is because communication between the production worker (worker) and the office worker (manager) is not smooth, so as to prevent crosstalk at the actual workplace, both the production worker terminal 200a and the office worker terminal 200b are connected to each other using a shared access code. It is possible to query, modify, delete the records of the database or to create instructions, report generation, etc. can be performed together in the application, such as applications installed in each terminal (200a, 200b).

Here, the production worker terminal 200a and the office worker terminal 200b connected to the monitoring system with a single access code are capable of real-time sharing or real-time conversation of the images taken through the terminals 200a and 200b. In case of abnormality, it is possible to understand the cause more easily, report is promptly resolved, and there is an advantage of narrowing the gap of understanding between production and office workers.
