2 is a diagram illustrating an internet based business management system according to an embodiment of the present invention.

As shown in FIG. 2, the Internet-based business management system according to an embodiment of the present invention includes a SaaS server 210 and an edge server 220.

The SaaS server 210 receives the site data through the edge server 220 and stores it in a database and, if necessary, checks the site data and generates control data. The control data may be configured to be transmitted to the edge server 220.

The edge server 220 is equipped with the work component received from the SaaS server 210 and supports the ubiquitous connection to communicate with wired and wireless equipment, execute the received work component to receive the field data from the wired and wireless equipment to store in the queue and a predetermined Upload the field data to SaaS server 210 in order. Meanwhile, the SaaS server 210 and the edge server 220 may be connected to the internet network.

The present invention uses the SaaS server 210 connected to the Internet instead of the method of installing an expensive server for each production site in a production site scattered with a variety of equipment. The SaaS server 210 may be configured as a software (Software as a Service: SaaS) component provided as a service for each production site required to service the work of the production site. SaaS server 210 and the edge server 220 of each production site can communicate with each other based on the Internet to transmit and receive data.

In the Internet-based business management system according to an embodiment of the present invention, the SaaS server 210 that is remotely located is selected and reconfigured to provide a business management service.

As described above, the SaaS server 210 provides an information service in which various SaaS components are packaged. When the user (or system administrator) selects a SaaS component to use and the environment is set, the SaaS component is set in the SaaS server 210.

SaaS component is set in the SaaS server 210, and equipped with wired and wireless equipment of the production site used for the work using the set SaaS component to register the unique number list of the equipment in the software SaaS component of the SaaS server 210.

The access to the SaaS server 210 uses a communication network, but a general wired / wireless communication network may be used as the communication network, but the present embodiment will be described assuming an internet network that can be used at a small cost.

However, when the SaaS server 210 and the wired / wireless equipment used for the service and the internet network are directly connected, the communication may be disconnected according to the network state of the internet network. Therefore, in the present invention, the edge server 220 is provided between the SaaS server 210 and the wired / wireless equipment so that the work performance can be continued even in a situation where the internet network is disconnected.

As described above, since the Internet-based business management system may cause delays and inconsistencies in the field information when the Internet is disconnected, the Internet-based business management system uses the edge server 220 in the present invention so that it can be applied to the field of business. It is placed between the equipment and the equipment so that work management can be performed even if the internet network is disconnected.

The edge server 220 may include a REST driver, which is a wireless communication unit, to transmit / receive data with the SaaS server 210 that provides a SaaS component.

The edge server 220 downloads and mounts a work component necessary for the operation of the equipment whose unique number is registered in the unique number list from the SaaS server 210, and is equipped with a component executor that can execute the work component. Allow the work component to run. The edge server 220 provides an interface for performing a specified task through a REST driver to wired / wireless equipment corresponding to a specified unique number using the executed work component.

The work component may include many work components such as an input work component that provides an input interface for a device registered in a unique number list, an alarm work component that allows an alarm to sound, and the like. The edge server 220 includes a component executor that enables execution of a work component. Meanwhile, work components of the edge server 220 may provide web services. Thus, for example, an input work component that is one work component in one edge server 220 may request a work to an alarm work component that is another work component and receive a result thereof.

The edge server 220 is to communicate with various equipment through the wired and wireless network of the production site. Equipment for communicating with the edge server 220 may include a work terminal, a computer, a portable input / output terminal, a PLC facility, and the like. The unique number list of such equipment is registered in the SaaS server 210, and the unique number list having the same contents is downloaded and stored in the edge server 220 to recognize the equipment of the corresponding list and communicate with the corresponding equipment to perform a task. can do.

Data transmitted from the pre-registered wired and wireless equipment to the edge server is set to communicate in a standardized format (eg, XML). That is, data transmitted from the wired / wireless device to the edge server may be transmitted in an XML format.

If the serial number list is registered in the database but is not yet in operation at the production site, it is already registered on the serial number list. It is possible to use as equipment.

Equipment connected by wire can be recognized by the edge server 220 that the equipment is added only by being connected to the network of the production site.

Wirelessly connected devices operate in an ubiquitous environment. Examples of the ubiquitous environment may include an Ad-hoc network or a Ubiquitous Sensor Network (USN). For example, each wireless device operating in ad-hoc mode supports a network that can determine routing paths on its own.

The edge server 220 is provided with a REST driver corresponding to the wireless device connection unit can be connected to the wireless equipment of the production site to send and receive data in real time. Each wireless device connected to the edge server 220 operates in an ad-hoc mode and thus cannot be directly communicated with the wireless connection. For example, the distance between the REST driver and the wireless device mounted in the edge server 220 may be reduced. Even if the direct communication is far away from each other, the network path is dynamically configured using each wireless device as a node so as to be able to communicate with the edge server 220. That is, the data may be transmitted and received by setting a path through another wireless device. Therefore, it is easy to add the radio equipment registered in the unique number list of the equipment as the operating equipment of the production site.

If the user wants to add a new device that does not exist in the unique number list, the unique number of the new device is registered in the unique number list of the SaaS server 210 and the same registered contents are loaded into the edge server 220's database. The unique number list of the equipment operating on the 220 is updated.

On the other hand, SaaS server 210 maintains a database required for the operation of the production management system. A part of the database of the SaaS server 210 is mounted to the edge server 220 is used for the operation and production management of the equipment, the database of the edge server 220 is always synchronized with the data on the SaaS server 210. The information stored in the database may include a list of unique numbers of the operating equipment, the set temperature of the equipment, work standard information required for the work, and the like, but the present invention is not limited thereto.

The edge server 220 is connected to many wired and wireless equipment of the production site. Data transmission and reception between the edge server 220 and the wired and wireless devices is the edge server 220 is provided with a REST driver for communication. The edge server 220 may receive data through a REST driver to define, collect, and filter data generated in the field or transmit control data from the SaaS server to the wired / wireless device. The data collected from the wired / wireless device may be queued. Queue).

The edge server 220 stores not only the input information input by the user from the equipment in the field but also data automatically received in real time from the equipment in a queue.

The edge server 220 transmits the data stored in the queue to the SaaS server 210 in a predetermined order. By storing it in a queue, it is possible to continuously collect data on the production site even when the Internet network is blocked. That is, even when the Internet network is blocked, the edge server 220 may upload the data in the queue to the SaaS server 210 in a predetermined order when the Internet network is accessible again while collecting the data continuously.

On the other hand, the edge server 220 may be required to store the necessary portion of the database of the SaaS server 210. That is, the database of the edge server 220 and the SaaS server 210 is set to be synchronized, and the updated database of the SaaS server 210 also synchronizes its contents to the edge server 220. The unique number list of the above-described operating equipment may correspond to this, or may correspond to a set temperature or a working condition.

The Internet-based business management system according to an embodiment of the present invention will be described by taking an example of a task for setting the temperature of the equipment at the production site.

Assume that a task is set such that the temperature setting of a certain equipment (hereinafter, referred to as equipment A) is set to 0 to 50 ° C. and information about the same is stored in a database of the edge server 220 and the SaaS server 210. The temperature setting information may be inputted by the administrator to the SaaS server 210 and then downloaded to the edge server. The operator inputs the set temperature by using a work component for inputting the temperature definition down to the edge server and the SaaS server 210. ) May be uploaded and stored in the database of the SaaS server 210. Of course, when defining temperature, you can also define actions if data outside the temperature range is collected. For example, when data outside the temperature setting range is collected, the alarm ringing task component downloaded from the SaaS server 210 to the edge server 220 is called to generate an alarm or to control the temperature of the heater of equipment A. You can enter a definition that allows you to take action to lower it.

When the temperature setting information is stored in the edge server 220 and the SaaS server 210 as described above, the edge server 220 receives the temperature information from the PLC collecting the temperature from the temperature sensor of the equipment A. The received temperature information is stored in the queue of the edge server 220, the edge server 220 transmits the information of the queue to the SaaS server 210 in a predetermined order. The predetermined order means a predetermined order that is set in such a way as to be transmitted in the order of high priority or in the order of collection.

The SaaS server 210 received the collection temperature from the edge server 220 checks whether the collection temperature is outside the set range. If the acquisition temperature is outside the set range, the control command may be transmitted to the work component of the edge server 220. For example, if the alarm is set to sound, it can be controlled to sound an alarm by sending a control message to the corresponding alarm sounding task component of the edge server 220.

As shown in FIG. 3, when a purchaser connects to the Internet and purchases an application such as 'production management' or 'schedule management', the application usage environment is set in the SaaS server, and the user can access the corresponding site. Edge servers and wired and wireless devices are installed here, and administrators register products in SaaS components and register work orders to begin managing the field work.

Data can be collected from wirelessly connected PDAs, RFID readers, as well as production facilities connected by wire.

Work components can be loaded from the SaaS server into the edge server. The loading process may be mounted by an administrator or automatically.

The edge server can execute the installed work components (automatically or manually) to provide input screens to each wired / wireless equipment connected by wire or wireless so that data can be collected and, if necessary, on-site such as statistical processing data such as production performance information. It is also possible to provide an output screen for expressing management information.

Collected data is collected through a queue, which is sent to SaaS server or stored in database of edge server.

The SaaS server may receive registration of wired or wireless equipment by the factory administrator or the edge server may register. It can also be configured to retrieve production status or other statistical data from the SaaS server.
