Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant information providing system,

The present invention relates to a plant facility information providing system and a method of providing the same, and more particularly, to a plant facility information providing system and method for providing facility facility information to a worker in order to check status, The present invention relates to a plant facility information providing system and a method for providing plant facility information, which can receive the position of an operator in real time without operation, identify facilities adjacent to an operator's location, and quickly provide relevant status information of the identified facilities.

When performing the status check, failure, and maintenance of the facilities located in the plant, the relevant status information of the target facilities is obtained by directly identifying the equipment by the operator (facility maintenance person, manager, user, etc.) (Map or the like), or by searching for a facility using an information terminal for maintenance support (special terminal, etc.), downloading the related state information and referring to it, or using an identification device And the related state information is downloaded through the identification of the facility.

That is, conventionally, the operators have to perform an operation for requesting the status information of the target facility by directly operating the identification means separately provided in the facility.

More specifically, conventionally, separate identification means such as an RFID tag or a beacon for identifying a facility is attached to each facility, and an operator is also provided with facilities for identification The state information of the related equipment can be received only after performing the operation for identifying the equipment, and the maintenance work is performed accordingly.

However, in the case of the RFID tag, not only is there a disadvantage that it is necessary to install the RFID tag in every facility located in the plant, but also anyone can receive the information of the target facility through the RFID recognition, which has a problem in security.

In addition, beacons are basically based on low-power Bluetooth, but they are also not useful in identifying individual facilities because they require a separate power supply system for use.

Particularly, in the case of a large-scale plant having more than 30,000 facilities, when the identification means for identification is attached to each facility and the management of the plant is performed through the identification means, the cost rise due to the identification infrastructure to be built in each facility And the state information of the equipment can not be quickly transmitted to the worker, and information is transmitted only after the identification operation of the worker is performed, so that the decision time becomes long.

In this connection, in Korean Patent Registration No. 10-1157631 (" ubiquitous-based power generation facility management system and method "), a facility history is searched through communication with a ubiquitous sensor attached to a power generation facility, And a system capable of performing maintenance and management of power generation facilities.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a system and method for providing plant facility information according to the present invention will be described in detail with reference to the accompanying drawings. The following drawings are provided by way of example so that those skilled in the art can fully understand the spirit of the present invention. Therefore, the present invention is not limited to the following drawings, but may be embodied in other forms. In addition, like reference numerals designate like elements throughout the specification.

In this case, unless otherwise defined, technical terms and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. In the following description and the accompanying drawings, A description of known functions and configurations that may unnecessarily obscure the description of the present invention will be omitted.

In addition, a system refers to a collection of components, including devices, mechanisms, and means that are organized and regularly interact to perform the required function.

The plant facility information providing system and the method for providing the same according to an embodiment of the present invention are for providing facility related information for diagnosing the state of adjacent facilities to a worker located in the plant and supporting the maintenance through the O2O (Online To Offline) service Conventionally, the operator has to directly recognize the identification means attached to / installed in the facility, so that the identification means must be attached to all the facilities located in the plant and the provision of the facility-related information can not be performed in real time There is a disadvantage that the diagnosis of status and maintenance support can not be performed quickly.

In order to overcome such disadvantages, it is necessary to confirm the position of the operator in the plant in real time and to provide facility-related information to the adjacent facilities on the basis of the information in real time. Equipment related information can be provided, and status diagnosis and maintenance support can be performed in real time.

The plant facility provision system according to an embodiment of the present invention includes a terminal unit 100 and a providing unit 200 connected to each other through a wireless network as shown in FIG. 1 as a facility information providing system for supporting plant maintenance .

Preferably, the terminal means 100 is a terminal means that can be carried when an operator enters a plant, and generally operates as a smartphone.

However, when security is important according to the plant, it is preferable to operate through a separate dedicated terminal rather than a smart phone which is easy to connect to an external network.

The providing means 200 is connected to the terminal means 100 through a wireless network, and is preferably configured to include a providing server.

To learn more about each configuration,

As described above, the terminal unit 100 is preferably a terminal unit that can be carried by an operator. Preferably, the terminal unit 100 includes a position information sensing unit 110 for sensing current position related information of the operator.

The position information sensing unit 110 may include a first sensing unit 111 for sensing the height information of the operator and a second sensing unit 112 for sensing the position information of the operator.

The first sensing unit 111 preferably includes an air pressure sensor for sensing height information of an operator. Generally, in the case of a plant facility, different facilities may be located at the same position depending on the height , Height information of the operator is necessarily required.

The first sensing unit 111 may collect altitude information of the operator using the atmospheric pressure sensor.

The second sensing unit 112 preferably includes a GPS or an IMU sensor to sense the position information of the operator, and it is most preferable to use all the GPS / IMU sensors.

In detail, both the GPS and the IMU sensors can specify the position information of the operator. However, in the case of GPS, since the accuracy of the positioning may be lowered when entering the inside of the plant, It is desirable to supplement the indoor positioning accuracy.

That is, when GPS is used, position information can be provided through communication with the satellite. However, when entering the room, communication with the satellite may not be easy, so it is preferable to use the IMU sensor.

At this time, the second sensing unit 112 may use only the GPS to sense the position information of the operator, or use both the GPS and the IMU sensors by the operator's input operation.

For example, when the operator selects and inputs an indoor positioning method used in the second sensing unit 112 through the input unit 130 provided in the terminal unit 100, Operation. However, when the operator does not select and input the indoor positioning method used in the second sensing unit 112, the position information of the operator is first specified through the GPS to provide status information of the facilities, It is desirable to increase the accuracy of the indoor positioning through the IMU sensor when it is determined that the operator is located inside the plant when the additional operation is performed due to the uncertainty of the location information such as the reselection request, the state information retransmission request, and the location information revalidation request.

Here, the IMU sensor is a geomagnetic field-based indoor position measuring technique, which is composed of a three-axis gyroscope and a three-axis accelerometer, and has an accuracy of 1 m or less in the positioning value. However, in order to apply the IMU sensor unlike the GPS which does not require a separate configuration in the facility, a magnetic field map is required to collect the magnetic field information of the plant in advance. The position information of the operator on the two-dimensional plane can be specified by mapping the position of the terminal having the IMU sensor on the magnetic field map, that is, the position of the terminal means 100 held by the operator.

The magnetic field map is preferably stored and managed by the first DB unit 210 of the providing unit 200, which will be described later.

The providing means 200 is connected to the terminal means 100 through a wireless network and can confirm the current position information of the worker using the current position related information of the worker transmitted from the terminal means 100, Based on the current location information, it is possible to provide information related to the plant facility adjacent to the operator.

The first DB unit 210 may store and manage the location information of the plant facility in a database. The location information of the plant facility means location information, altitude information, magnetic field map, and the like of each facility located in the plant, and is not limited to these, and preferably means all information related to the location of the plant facility .

The second DB unit 220 may store and manage the state information of the plant facility in a database. The status information of the plant facility includes specifications of each facility located in the plant, design information, facility drawings, PHI (Plant Health Index), facility operation performance information, failure history information, and maintenance history information. But is not limited to, all information relating to the state of the plant facility.

The location information and the state information of the plant facility stored in the first DB unit 210 and the second DB unit 220 can be updated as needed by a manager (worker, facility maintenance person, user, etc.) Additional information related to plant facilities in operation of the plant, such as additional construction and additional maintenance by status diagnosis, is updated in real time, so that the operator can smoothly provide facility information for plant maintenance support.

The position information determination unit 230 can determine the current position information of the in-plant operator using the height information and the position information, which are information related to the current position of the worker, transmitted from the terminal means 100. [

That is, as described above, the position information determination unit 230 determines whether or not the altitude information of the operator, which is collected by using the atmospheric pressure sensor in the first sensing unit 111 of the position information sensing unit 110, 2 sensing unit 112, and can determine the current position information of the operator on the three-dimensional plane. The position information determination unit 230 determines the current position information of the operator on the three-dimensional basis, so that different facilities at the same position in the plant, such as the scale of the plant or the position of the facility, It is important to determine the current position information of the operator on three dimensions.

The facility location identification unit 240 uses the location information of the plant facility stored and managed by the first DB unit 210 to perform matching based on the current location information of the operator determined by the location information determination unit 230 The equipment to be identified can be identified.

Specifically, it is possible to identify a facility in which the location information of the plant facility stored in the first DB unit 210 matches the current location information of the operator.

The facility location identification unit 240 preferably identifies a facility within a predetermined range based on the current location information of the operator.

Preferably, the predetermined range is set by a manager (an operator, a facility maintenance person, a user, or the like) as needed, and it is possible to identify only facilities next to the current position information of the operator according to the setting range, It is also possible to identify the facilities.

In this case, the facility location identification unit 240 identifies, based on the preset range, the list information of a plurality of facilities identified in accordance with the preset alignment criteria when the number of facilities identified based on the current location information of the operator is equal to or greater than a predetermined number Lt; / RTI >

In other words, the facility location identification unit 240 can identify a facility within a preset range based on the current location information of the operator. If only one facility is identified, state information on the corresponding facility is transmitted to the operator However, when two or more facilities are identified, it may be difficult to support the maintenance if state information on all the identified facilities is provided to the operator. Therefore, Management is required.

For this purpose, it is preferable that the facility location identifying unit 240 sets the predetermined number to three, which is only one embodiment of the present invention. The facility location identifying unit 240 may be configured by a manager (an operator, a facility maintenance person, a user, can be changed.

For example, if two pieces of equipment less than the predetermined number are identified in the equipment location identification unit 240, state information about the two identified equipment can be provided to the worker. However, When the facility is identified, list information of the facilities can be generated in accordance with a preset alignment criterion.

The sorting criterion can be set by the level ranking of the plant system, the degree of position proximity, the accuracy of position, and the like, which can also be changed / set as needed by an administrator (operator, facility maintenance person, user, etc.).

The facility information providing unit 250 may use the state information of the plant facility stored and managed in the second DB unit 220 to store state information matched with the facility identified by the facility location identifying unit 240 To the terminal means (100).

At this time, when the facility location providing unit 240 identifies the facilities less than a predetermined number, the facility information providing unit 250 matches the state information of all identified facilities to the terminal unit 100 Lt; / RTI >

When the facility location identification unit 240 identifies a predetermined number or more of the facilities, the list information of the generated facilities is received and transmitted to the terminal means 100, and then the information is returned from the operator, that is, It is preferable that the state information is matched and transmitted to the terminal means 100.

For this, the terminal unit 100 may further include a monitoring unit 120 and an input unit 130, as shown in FIG.

The monitoring unit 120 may output the plant facility related information received from the providing unit 200. [ In this case, when the facility location identification unit 240 identifies a number of facilities less than a predetermined number, the plant facility-related information that is output may receive and output state information on all the identified facilities, It is possible to receive and output the list information generated using the identified facilities.

The input unit 130 can receive desired facility information from the operator among the plant facility related information output through the monitoring unit 120. [

That is, when the list information is outputted through the monitoring unit 120, the operator can select and input facilities desired by the operator among the identified facilities, and the facility information providing unit 250 can receive the facility information And transmits the matching information to the monitoring unit 120 of the terminal unit 100.

That is, in other words, the plant facility information providing system according to an embodiment of the present invention confirms the position of the worker in real time even if the worker located in the plant does not perform a separate identification operation for identifying the facility, By providing the information, not only the plant maintenance support can be effectively performed, but also the operator's decision time can be shortened during maintenance.

As shown in FIG. 2, the plant facility information providing method according to an embodiment of the present invention is a facility information providing method for supporting plant maintenance. The method includes providing a terminal unit 100 and a providing unit 200 connected through a pre- A location determination step S200, a facility identification step S300, a state information processing step S400, and an information providing step S500.

To learn more about each step,

In the position receiving step S100, the providing means 200 may receive the current position related information of the operator from the terminal means 100 possessed by the operator.

In detail, the position receiving step S100 receives the height information and the position information, which are information related to the current position of the operator, from the terminal means 100 in the position information determination unit 230 of the providing means 200 have.

The current position related information of the operator is preferably obtained through the position information sensing unit 110 of the terminal unit 100. [

The position determination step S200 determines the current position information of the worker using the current position related information of the worker received in the position receiving step S100 in the position information determination unit 230 of the providing means 200 can do.

In other words, the position determining step (S200) can determine the current position information of the in-plant operator using the height information and the position information, which are the current position related information of the worker, transmitted from the terminal means 100. [ More specifically, it is possible to receive the altitude information and the position information of the delivered operator, and to determine the current position information of the operator on the three-dimensional plane.

By determining the current position information of the operator on the three-dimensional basis, different facilities can be located at the same position in the plant, such as the scale of the plant or the position of the facility, It is preferable to determine the current position information of the mobile terminal.

The facility identification step S300 is a step of identifying the current location information of the operator determined in the location determination step S200 using the location information of the plant facility stored in the first DB unit 210 of the providing means 200 It is possible to identify a facility within a preset range.

That is, the facility identification step S300 is performed in the facility location identification unit 240 of the providing means 200, based on the current location information of the operator determined in the location determination step S200, The location information of the plant facility being stored and managed in the facility can be identified.

Preferably, the predetermined range is set by a manager (an operator, a facility maintenance person, a user, or the like) as needed, and it is possible to identify only facilities next to the current position information of the operator according to the setting range, It is also possible to identify the facilities.

For example, if only one facility is identified, state information about the corresponding facility may be transmitted to the operator's terminal means 100, but if more than one facility is identified, then all identified facilities It is necessary to control the maintenance of the worker because it may cause difficulties in the maintenance support.

3, in the facility identification step S300, the plant facility information providing method according to an exemplary embodiment of the present invention may identify the plant facility information based on the current position information of the operator according to the preset range It is preferable to determine whether or not the number of facilities to be installed is a predetermined number or more.
