The communication unit 14 preferably communicates with the resource information collector 20 using a short-distance wireless communication method.

After the connection with the resource information collector 20 is established, the sensor node acquires the production resource information from the installed production equipment, configures the transmission message with the acquired production resource information, and selects either the push method or the polling method To the resource information collector (20). Here, the push method refers to a method of transmitting a transmission message in real time or periodically to a resource information collector, and the polling method is a method of transmitting a transmission message to the resource information collector only when data transmission is requested by the resource information collector it means.

The resource information collector 20 assigns a node unique number to the automatic production resource information generation unit 10 and groups the automatic production resource information generation unit 10 into nodes to be managed. In particular, the resource information collector 20 manages a plurality of sensor nodes and plays a role of relaying data between the plurality of sensor nodes and the middleware 40.

The resource information collector 20 transmits the automatic production resource information transmitted from the automatic production resource information generation unit 10 to the middleware 40 through TCP / IP based communication.

3, the resource information collector 20 includes a wireless communication unit 21 for short-range wireless communication with the sensor node, which is the automatic production resource information generation unit 10, A control unit 23 for controlling data transmission / reception between the sensor node and the middleware, a node unit 23 connected to the control unit 23, A node unique number assigning unit 25 for assigning a unique number to the sensor node and a node grouping unit 25 for grouping the sensor node, And a grouping unit (26).

The manual production resource information generation unit 30 generates manually generated production resource information as worker information, parts information, and production work instruction information, which are input according to an operation of a manager, and transmits the generated manual production resource information to the middleware 40. The manual production resource information generation unit 30 plays a role of transferring the production resource information which is carried by the task manager and can not be automatically collected on the spot, to the manual middleware 40 in accordance with the input of the task manager do.

The middleware 40 receives the production resource information acquired by the automatic production resource information generation unit 10 and the production resource information acquired by the manual production resource information generation unit 30, Process control unit, and generates control information by analyzing production resource information for each classified manufacturing process control unit. Although the middleware is software, the present invention means a production resource processing server that processes production resource information. Middleware and components are needed for actual production resource processing.

4, the middleware 40 includes an automatic production resource information collection module 41 for collecting production resource information based on TCP / IP with the resource information collector 20 through a single platform; A manual production resource information collection module 42 for collecting production resource information on the basis of the short-range wireless communication with the manual production resource information generation unit 30; The production resources are defined in real-time by the automatic production resource information collection module 41 and the manual production resource information collection module 42, and based on the production resource information, And a production resource processing module 43 for extracting the worker information and constructing a resource.

The production resource processing module 43 includes a function of storing the resource status value extracted from the received production resource information and informing the outside of the event occurrence when the production resource information includes the event occurrence information.

The operation of the production resource autonomous management system based on the wire / wireless sensor network according to the preferred embodiment of the present invention will be described in detail as follows.

If production facilities are changed in the field by adding new production facilities, moving production facilities, or removing production facilities, it is necessary to manually register the information on the changed facilities in the system so that the operation manager manually registers the production resources. There is an inconvenience.

However, according to the present invention, only the automatic production resource information generator 10 including the sensor node is installed in the production facility, and the operation manager operates only the connection setting button provided in the operation unit 12, The automatic connection setting between the mobile terminal 20 and the mobile terminal 20 is established.

For example, as shown in FIG. 5, when the sensor node is attached to the production facility by the variation of the production facility (S11), the operation manager operates the setting button provided on the operation unit 12 (S12 ).

When the setting button is operated, the control unit 13 recognizes the beacon message, generates a beacon message for establishing a connection with the resource information collector 20, and transmits the generated beacon message through the communication unit 14, And transmits the signal to the resource information collector 20 (S13, S14).

The resource information collector 20 receives the beacon message transmitted from the sensor node through the wireless communication unit 21 in step S15 and the beacon message is received from the storage unit 24, And controls the node unique number assigning unit 25 and the node grouping unit 26 based on the retrieved control program. The node unique number assigning unit 25 assigns a node unique number (ID) to the sensor node that transmitted the beacon message, and the node grouping unit 26 assigns a node unique number The node unique number is registered in the sensor node group to perform node grouping (S16). Here, the node unique number is information for identifying the sensor node, and recognizes the production facility installed on the site through the node unique number. The node grouping means that one resource information collector 20 binds sensor nodes to be managed.

Upon completion of the node unique number assignment and node grouping, the controller 23 generates a beacon response message including the node unique number and the node grouping information, and transmits the generated beacon response message to the communication module 22 via the beacon message To the transmitted sensor node (S17).

The communication unit 14 of the sensor node receives the beacon response message and transmits the beacon response message to the control unit 13 in step S18 and the control unit 23 extracts the group information and the node unique number from the received beacon response message, (S19).

Then, the group information and the node unique number are allocated to the communication header (S20). Then, a configuration message is generated and transmitted to the resource information collector 20 through the communication unit 14 (S21). Here, the configuration message is preferably a message including information for establishing a connection, and may include the group information and the node unique number information.

Upon receiving the configuration message through the wireless communication unit 21 (S22), the resource information collector 20 extracts the node unique number included in the configuration message received by the control unit 23, (S23). As a result of the check, if the node unique number assigned by the node is correct, a response message is given to the sensor node to establish a connection (S24).

If the sensor node transmits a message regarding the production resource information to the resource information collector in a state in which the connection establishment is made in the sensor node and the resource information collection period, the group information and the node unique number are included in the previous stage of the message, It is possible to easily confirm whether the node is a sensor node of a group managed by itself.

The sensor node having completed the connection setup with the resource information collector 20 acquires the information of the production resource through the production resource sensing unit 11 in real time. For example, production resource information is obtained by detecting the production facility detection information such as temperature, weight, production quantity, and the like. Thereafter, the control unit 13 converts the acquired production resource information into automatic production resource information in real time or periodically, and transmits it to the resource information collector 20 through the communication unit 14 (S25).

In this case, when the production resource information is detected using the push method, the production resource information is transmitted to the resource information collector 20 unconditionally or the resource information receiver 20 transmits the automatic production resource information to the sensor node 20 using the polling method Only in response to the request.

The resource information collector 20 receives the automatic production resource information from the plurality of sensor nodes, that is, the grouped sensor nodes. The resource information collector 20 receives the automatic production resource information from the sensor node in the middleware 40 by the TCP / IP communication method through the communication module 22 Resource information is transmitted.

In this manner, the middleware 40 acquires the automatic production resource information transmitted from all the sensor nodes provided at the corresponding site through all the connected resource information collectors.

Meanwhile, the above-described method using the sensor node is applied only to the production resources that can acquire the production resource information automatically, and it is possible to use the production resource information that can not acquire the production resource information automatically, The production manager must manually collect and transmit production resource information directly to the information to be collected or to the production work instruction information as part information. In the prior art, it is impossible to accurately and efficiently manage the production information because the manual production resource information is not considered. In the present invention, however, such manual production resource information is also utilized for production resource management.

For example, the task manager can directly use the manual production resource information generating unit 30, which is a dedicated terminal for transferring production resource information that is provided at a certain place to carry the production resource information manually or manually, To the middleware 40, production resource information that can not be acquired automatically. That is, the manual production resource information generation unit 30 generates the production resource information input by the task manager by using the Web service approach, and transmits the metadata to the middleware 40 using a normal Web service connection and invocation protocol . To this end, the manual production resource information generator 30 generates a function for switching the legacy component to the web service and an interoperability channel for the wrapping class.

Here, a wireless communication method such as a wireless Internet may be used between the manual production resource information generating unit 30 and the middleware 40, and data can be transmitted / received using a wired communication method such as RS-485.

The middleware 40 collects the automatic production resource information transmitted from the resource information collector 20 through the automatic production resource information collection module 41 and delivers the collected automatic production resource information to the production resource processing module 43. The manual production resource information transmitted through the manual production resource information generation unit 30 is transmitted to the production resource processing module 43 through the manual production resource collection module 42. [

The production resource processing module 43 extracts tag information (group information and node unique number) from the collected automatic production resource information and manual production resource information, and temporarily stores the production resource information in the memory based on the extracted tag information .

Then, the production resource information received by each manufacturing process management unit (Workcenter) is grouped based on the tag information. For example, 4M resources are defined for each manufacturing process management unit in real time, and data collected by defining industry process management such as performance information, equipment information, and worker information are classified based on the definitions.

Then, it analyzes the classified data and monitors the event data and generates information on the operation, non-operation, failure, and real-time status information of the work instruction according to the manufacturing process management unit through the information analysis, and provides it to the manager through the screen etc. . In particular, the production resource processing module 43 stores the resource state value extracted from the received production resource information, and when the event generation information is included in the production resource information, the production resource processing module 43 informs the outside of the event occurrence through an alarm or the like.

In order to improve the event processing capability in the middleware 40, the present invention uses an event compression transmission method to prevent large bottlenecks of 4M process management processing capacity expansion and mass event processing. By using such an event compression transmission method, it is possible to multiprocess the central processing unit (CPU) and increase the efficiency of the large-scale field management.

Although the present invention has been described in detail with reference to the above embodiments, it is needless to say that the present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the spirit of the present invention.

The present invention is applied to production resource management technology for automatically acquiring production resource information and efficiently managing production resources based on the acquired production resource information. In particular, it can be effectively applied to manufacturing industries that need to efficiently manage production resources.
