Platform for smart factory construction and maintenance {Platform of Smart Factory}

The present invention is a technology related to a platform for the construction and maintenance of a smart factory. In order to reduce the cost of building and maintaining a smart factory, the present invention develops a data processing agent program that reacts in real time to external files in INI (Initialization) format. It is about technology.

Among the components of the'Smart Factory', the pre-processing and analysis of the current status of Big Data is the first step that enables the Smart Factory, and is a necessary part for the advancement of the Smart Factory.

Pre-processing and status analysis is a method of importing information in real time through a contact point at the main occurrence point of the device. Most of the data is obtained through serial communication or TCP communication method through'data collection software' provided to the collection device manufacturer. Driven by.

However, since these data are simple phenomenon data and are not information that can be used as a KPI (Key Performance Indicator), the manufacturer developed a separate'integrated data collection software' by requesting a system integration (SI) company to utilize it. As a result, the data is stored and analyzed in a central server to be used as various management, production, and quality information.

In particular, at the manufacturing site, due to the diversification of device makers, diversification of data protocols, and diversification of data generation time points, high costs are incurred in developing'integrated data collection software', and maintenance is also difficult.

Currently, domestic programmable logic controller (PLC), manufacturing execution system (MES), and enterprise resource planning (ERP), such as device control hardware and management information system. Although it is equipped with technology, the level of a standardized pre-processing platform that can be easily integrated through this is in a poor situation.

As such, there are many foreign platforms and the inability to develop independently, so it is difficult to pay expensive royalties, outflow of operational know-how, lack of core technology, and improve fundamental competitiveness, and dependence on foreign companies cannot gradually increase.

Therefore, it is urgently required to develop a localized'smart factory pre-processing platform' suitable for international standards, making it easier for SMEs to build and maintain a'smart factory', reduce redundant development costs, and meet international standards.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Bars shown in the following description and accompanying drawings are presented for a general understanding of the present invention, so the technical scope of the present invention is not limited thereto. In addition, detailed descriptions of known configurations and functions that may unnecessarily obscure the subject matter of the present invention will be omitted.

1 is a system diagram of a platform for smart factory maintenance and maintenance according to an embodiment of the present invention, FIG. 2 is an exemplary sequence diagram of a data processing module, and FIG. 3 is a smart factory maintenance and repair according to an embodiment of the present invention. This is the overall flow chart of the platform for.

Referring to FIG. 1, the present invention is a platform for smart factory maintenance and repair, and includes a device processing module 100, an INI processing module 200, a data processing module 300, and a transmission/reception module 400,500.

First, the device processing module 100 is a programmable logic controller (PLC), input/output port (I/O port), serial port, Internet protocol (TCT/IP), DBMS (Database) for each device installed in the smart factory. Management System) and device-specific characteristics of external files (XLS, SQL) can be recognized in a specific code designated in the INI file 220.

The device processing module 100 can be accessed by naming'Section A'as an example in FIG. 3 and adding various PLCs and collection modules of external devices.

If the user needs to use the TCP/IP device, when the INI file 220 writes the name and value according to the parameter for'Section A', the processing is performed within the target time by the agent program.

When the module is normally operated by the user interface of the agent program 600, the device processing module 100 increases the number of devices by 1, and the device list includes, for example, ' It appears as'Station 1'and provides a function to check the detailed information (connection setting information and operation status) of the device.

The INI processing module 200 is a module that names an INI file, and is a module in which a user controls an operation by an agent program.

Here, the file name is named in the form of'Geform.ini' as an example in FIG. 3. The basic INI grammar is used for the user's ease of use, and some additional extension functions can be provided.

In addition, in the agent program 600, whether the INI file 220 runs normally through the device list screen, data collection list screen, data transmission list screen, and data processing status screen in the user interface. Provides a function to check.

The data processing module 300 is a module that performs an operation according to a processing method designated by a user.

The data processing module 300 receives the device-specific data and performs an operation for setting the INI file 220.

Here, in the INI file 220, the data processing section can be defined as'Section M'as an example in FIG. 3, and the operation is sequentially discrete and logarithmic from'M0001' to'M9999' according to the processing ID (ID). algebra) operation is performed, and the result is stored in a data output stack, for example in FIG. 2. Referring to FIG. 2, in the data processing module, in order, data processing index, data processing syntax Get, data processing syntax parsing, data collection data request, data operation/processing, data output area Index Matching, output data Insert to Stack. You will go through the process. In the data processing syntax parsing step, information may be additionally received through mutual communication with the INI processing module 200, and a request for data collected in the data sector may be obtained through the data receiving module.

When the original value ID (ID) has a value of '01000' in'F0001' and a value of '11000' in'F0003', and you want to change the value in'F0003' to '01000' through AND operation Yes.

The transmission/reception modules 400 and 500 set a format for fetching and sending data of the device, and fetching and sending data to a designated memory.

The data transmission/reception part in the INI file 220 is defined as'Section F'and'Section G'as examples in FIG. 3, and supports ASCII, Binary, Hex Code and Bit formats according to the type setting, and the segment of each item is They are separated by commas (,).

For example, if the device is a PLC, when connected normally, the receiving module reads the value of the memory address, and if successful, the data processing module 300 is executed, and the transmitting module 400 approaches the device according to the output setting and is waiting for output. Receives a value from the stack and prints it. The connection method for each output device is the same as the data collection connection method.

The present invention described above is not limited to the above-described embodiments, and any person having ordinary knowledge in the technical field to which the present invention pertains without departing from the gist of the present invention claimed in the following claims can be changed in various ways. It should be regarded as belonging to the scope of protection of the claims to the extent that can be implemented by doing so.
