Description

[0001] Manufacturing Information Monitoring System for Manufacturing Process [

The present invention relates to a production information monitoring system for a manufacturing facility, and more particularly, to a production information monitoring system specialized for production related information such as production facility status, production volume, materials, and production personnel of a manufacturing-based SME.

Most industries, especially the manufacturing sector, are rapidly shifting to information technology or digitalization based on IT technology. However, in most SMEs, the initial investment cost has increased and it is not possible to promote it. In the case of SMEs in Korea, it is difficult to meet the time and expense required to customize them to the production site or management / resource management system according to the functions required due to the weakness of capital. Many commercialized IT solutions are introduced as products developed at the level of domestic large corporations or foreign companies, and most of them are not suitable for small and medium enterprises in Korea.

In addition, it is difficult to provide a knowledge management system that overcomes manufacturing and production-based technologies that are dealt with in actual manufacturing sites because of the characteristics acquired and experienced through experience in the field facilities. It is necessary to build a system that can easily utilize information system without technology to be able to use information effectively without expert knowledge or new employees (lack of dedicated department and high turnover rate).

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. However, the scope of the present invention is not limited to the description or drawings of the embodiments below.

FIG. 1 is a diagram showing the configuration of a production information monitoring system of the present invention. FIG. 2 shows an application example of the production information monitoring system of the present invention, and FIG. 3 is a conceptual diagram of a data logger of the present invention.

1, the production information monitoring system of the present invention includes a data acquisition unit 10, a data logger 20, a logger data processing unit 30, an intermediate server 40, and a main server 50.

The data acquiring unit 10 acquires data using a sensor or a barcode reader attached to a production facility or a management facility.

2, the data acquiring unit 10 may be a barcode printer attached to a production facility (for example, a forging facility), a barcode reader, a counting unit for measuring the number of operations of the facility, have.

3, the data acquiring unit 10 may be at least one production counting module, a status abnormality sensing module, or a device operation management module attached to a production facility or a management equipment installed in operation.

The data logger 20 receives data from the data acquisition unit 10 in real time, and obtains valid data through noise cancellation. That is, the data logger 20 can acquire various kinds of information of the production equipment and the management equipment through the data acquisition unit. The data logger 20 may include an IN / OUT board for receiving data information of the data acquisition unit, a control unit for removing digital noise from the received data, and a communication unit for data transmission.

The control unit of the data logger may include a process (algorithm) for digital noise cancellation to obtain valid data. For example, the control unit measures the data once every 10 ms after the sensor is turned on to acquire a total of 26 data. 20 pieces of data acquired from the 26 pieces of data in total are sequentially removed, and the six pieces of data acquired later are stored. In addition, the average value of the four pieces of data obtained by removing the maximum and minimum values of the six pieces of data is obtained and transmitted to the data processing unit 30 through the communication unit.

The logger data processing unit 30 classifies valid data collected from the data logger into real time data and event time data generated by a production condition or a running condition, and transmits the data to an intermediate server or a main server, respectively.

The logger data processing unit 30 includes a controller 31 that is mounted on the worker interface PC and extracts event time data according to conditions input from real time data transmitted from the data logger in real time, . The control unit 31 of the data processing unit may program the input conditions or processes (algorithms) of the user to extract event time data

The logger data processor 30 classifies the real time data into real time data and event time data, and transmits the real time data to the intermediate server 40 and the event time data to the main server.

The real time data is valid data transmitted in real time from the data logger, and the event time data is data generated by the input production condition or operation condition. For example, the real time data is a value obtained by counting the number of press operations of the forging equipment in real time, and the event time data is a value counted once every 100 times of the press operation. The real-time data may represent the total number of unit products produced in the forging process, and the event time data may represent the unit output of the unit products bundled into 100 pieces. In the above example, it is effective to manage the management of production products (daily, weekly, monthly production, increase quantity, order quantity, sales) in a package unit of 100 products because sales are generated in a package unit.

As described above, the event time data is data that is necessary and efficient for production management, and is data extracted (computed) from the real time data in accordance with conditions preliminarily inputted by the user.

The intermediate server 40 stores and monitors real-time data transmitted from the data processing unit.

The intermediate server 40 includes a real time data storage unit 41 for receiving valid data from the logger data processing unit in real time and storing the real data and a control unit 42 for checking and monitoring the real time data . The intermediate server includes a TCP / IP socket and a user interface module (UI module) required for monitoring and a monitoring unit displaying real-time data in real time so as to enable network communication with the data processing unit and the main server.

The main server 50 may store and monitor event time data transmitted from the data processing unit.

The main server 50 receives the event time data of the data processing unit 30 via the TCP / IP socket and stores it in the storage unit 51. The controller 52 of the main server 50 may transmit the event time data to each management PC 53 according to the user's request or the input management condition.

The main server 50 receives only the event time data necessary for production management and processes the event time data, thereby reducing the load on the main server. On the other hand, the control unit 52 of the main server routinely processes the event time data, but the main server can access the intermediate server and monitor all the real time data if necessary.
