Description

TECHNICAL FIELD [0001] The present invention relates to a power plant management system and method using an Internet,

The present invention relates to a power plant management system using the Internet, and more particularly, to a power plant management system using objects Internet that can share real-time operation information of a device in a power plant in real time System and method.

Maintenance work of power plants (either nuclear, thermal, or hydropower plants) is divided into regular maintenance and planned preventive maintenance, all of which are performed in advance through planning, quality, approval of work, work and return.

Design and manage start and end times at every step, and actual start and end times are recorded. This is basically used for efficient process management, but it is also being used in the aspect of risk management such as preventing equipment that is important in terms of power plant risk from being operated at the same time.

These management programs are traditionally based on the information recorded on the paper by outputting the work order to the paper, and the execution history per actual work step is managed by a handwriting or computer system. We use spreadsheet to use this work history information for other purpose such as risk management.

Work information for the maintenance of existing power plants has been managed in the form of handwritten information on the ground. Recently, with the introduction of enterprise resource management system, users have manually input the execution history of each activity per unit work using a computerized system.

In the case of an activity that an operator has to deal with urgently and a task in which a large number of workers are input, the activity execution time can not be input in real time, and it is difficult to manage the real time performance by inputting later. In addition, as the demand for various applications using legacy programs increases, it is difficult to manage vast amount of work information by the conventional management method. In addition, since the work information is manually input and managed by the operator and the computer system user, there is a possibility that a human error may occur at the time of input because the user manages a vast amount of information about the work time information in a limited time.

In addition, in the conventional network in the power plant, the communication between the on-site inspector and the operator terminal for controlling each device is blocked in order to prevent an accident caused by hacking or leaking out. Therefore, in the past, a site supervisor of a facility in a power plant has created a site report by checking the operation information of each device as an operator and a radio in the main room controlling the operation of the device.

In other words, conventionally, since the network of the power plant is configured to be separated from each other for control and monitoring, the operation information can not be shared in real time between the operator of the field inspector, the operator of the main engine room, There is a problem in that it is difficult to quickly cope with an unexpected situation.

Further, conventionally, when a new apparatus or system is installed in a power plant, the system is put in operation after commissioning for a certain period of time. Here, conventionally, there is no method for automatically obtaining a test run check item (for example, temperature, vibration and pressure, presence / absence of opening / closing of a valve, and the like) set for each device or system in the trial run, And visited them to check them directly using a measuring instrument. However, due to the nature of the power plant, there is a space where the worker can not work or there is a place where it can not be contacted, so that there is a problem in that it is impossible or impossible to obtain data necessary for the inspection in the apparatus or system during the test operation.

The driver terminal 80 is a main control room terminal for controlling the start and stop of the device member 30 for each device. Here, the device of the device member 30 is started and / or stopped under the control of the driver terminal 80, and the control and / or the meter installed for each device measures data according to the set item in the start and / And transmits it to the driving information server 40 in real time. Here, the data measured and transmitted for each device corresponds to operation information for confirming the start and / or stop state.

The unidirectional transmission unit 60 allows unidirectional communication between the operation information server 40 and the monitoring member 10 in order to prevent security, safety, and malfunction. That is, the unidirectional transmission unit 60 outputs the real-time operation information and the previous operation information including the data of the start and / or stop state of each device received from the operation information server 40 to the monitoring member 10, (30) from the management terminal (10) and other manager terminals (70).

The operation information server 40 transmits the operation information of the device member 30 to the monitoring member in real time and stores the previous operation information in the data DB 41 together with the measured time of the operation information. In addition, the operation information server 40 transmits an alarm event for a failure or an abnormal situation.

The real-time operation information is data measured at the present time in the control and measurement equipment included in the device member 30, and the stored operation information is transmitted to the monitoring member 10 according to the time or condition set as data stored in the past.

The alarm event of the operation information server 40 is transmitted to the administrator terminal 70 and / or the driver terminal 80 via the unidirectional transmission unit 60 as an alarm according to an abnormal situation generated during the start and / .

The monitoring member 10 includes a field terminal 100 for inputting site acquisition information confirmed by the on-site operator on site, a monitoring server 200 for transmitting operation information to the site terminal 100, A mobile server 500 that converts the operation information output from the mobile terminal 200 into wireless data and transmits the wireless data to the field terminal 100, an identification tag 400 that performs near field wireless communication with the field terminal 100, And a secure terminal 600 for confirming whether or not the security data is stored in the secure terminal 100.

The identification tag 400 records the unique identification code of the power plant unit and the URL information of the monitoring server 200 and / or the mobile server 500. Here, the unique identification code corresponds to the unique identification information that can identify the devices stored in the monitoring server 200. [ The identification tag 400 can be selected from RFID and NFC tags in which a unique identification code is recorded.

The monitoring network 20 includes a wireless network for relaying wireless communication between the field terminal 100, the monitoring server 200 and the administrator terminal 70 using the mobile server 500 and the wireless repeater 510, 100, a monitoring server 500, and an administrator terminal 70. In this case,

The wireless network includes a mobile server 500 connected to the monitoring server 200 and / or the manager terminal 70 and a wireless repeater 510 relaying wireless signals between the mobile server 500 and the field terminal 100 ).

In the wired network, the monitoring server 200, the administrator terminal 70, and the field terminal 100 are connected to a wired line inside the power plant.

The mobile server 500 relays the communication between the field terminal 100 and the monitoring server 200 and / or the wireless signal between the field terminal 100 and the field terminal 100. That is, the mobile server 500 transmits the identification code and the alarm information received from the field terminal 100 and the site report to the monitoring server 200, and displays the start / stop state and the real-time operation received from the monitoring server 200 To the on-site terminal 100, the information on the operation of the vehicle, the previous operation information and / or the maintenance information.

Here, the radio repeater 510 may be a mesh type (e.g., a sole repeater, a mobile communication network of a mobile communication company (LTE), or the like) so as to relay radio signals between the entire area within the power plant, , 2.4G, 5G). For example, the operation information request signal including the identification code from the field terminal is received first in the first wireless repeater (not shown), and the second wireless repeater and the third wireless repeater (not shown) in the first wireless repeater, And transmits the wireless signal to the mobile server 500. [ In contrast, the operation information of the monitoring server 200 is output from the mobile server 500 in a wireless manner. In the third wireless repeater (not shown) receiving the wireless signal of the mobile server 500, And transmitted to the field terminal 100 via the repeater sequentially.

That is, a plurality of wireless repeaters 510 of the present invention are installed in a mesh type to relay radio signals between the mobile server 500 and the field terminal 100.

In addition, the present invention can wirelessly connect the field terminal 100 and the monitoring server 200 as a wire. This will be described with reference to FIG.

4 is a diagram illustrating a wired network between a field terminal and a monitoring server according to another embodiment of the present invention.

4, the present invention differs from the above-described transmission / reception of data between the field terminal 100 and the monitoring server 200 by the wireless repeater 510 and the mobile server 500, And configures the monitoring network 20 to be connected.

For example, the monitoring network 20 installs connectors 21 (e.g., USB) on a number of branch lines that each extend from a cable extending from the monitoring server to a device specific location. Here, it is preferable that the connector 21 is provided for each device, and unique identification information corresponding to the identification code included in the identification tag 400 is given.

Accordingly, information sharing and state propagation can be quickly performed between the field terminal 100 and the field terminal 100, the administrator terminal 70, and the monitoring server 200 through wireless transmission and / Lt; / RTI >

Here, the operation information includes at least one of measurement data of at least one of frequency, presence / absence of opening and closing of valves, humidity, pressure, number of revolutions, and temperature as real time and previous operation information received from the unidirectional transmission unit 60 by the monitoring server 200 .

The real-time operation information is transmitted in real time to the field terminal requesting the operation information as the identification code. Therefore, the field terminal is updated in real time from the operation information that is output first since the operation information of the device is received in real time.

Maintenance information includes, for example, at least one of drawings, previous work reports, manuals, documents and images for maintenance such as piping leaks, oil leaks, and the like. The maintenance information is stored in the monitoring server 200 and transmitted when there is a request from the field terminal 100 and / or the administrator terminal 70. [

The site acquisition information is obtained by checking the operating state of the apparatus at the site by the site inspector and displaying the operation state information (for example, temperature, pressure, frequency, rotation number , Power and current values), information that has been confirmed on site in relation to maintenance (eg, progress and results of equipment repair and replacement operations, installation and results of new equipment).

The security terminal 600 senses the presence or absence of data stored in the field terminal 100 (for example, site acquisition information and operation information), and transmits a forced deletion command to the site terminal 100. Here, the security terminal 600 is installed at a position where one or more of the security terminal 600 is installed inside and / or outside the power plant, and detects the on-site or on-the-spot field terminal 100.

The monitoring server 200 registers the information of the field terminal 100 and the identification tag 400 and receives the real time operation information and the previous operation information from the operation information server 40 and stores the real time operation information and the previous operation information in the database 300, 100). At this time, the monitoring server 200 assigns and records each unique identification code to the identification tag 400. Therefore, the monitoring server 200 classifies and stores the operation information received from the power plant unit into an identification code.

For example, when a situation related to start / stop and / or maintenance of the power plant occurs, the monitoring server 200 transmits the state of the corresponding device to the field terminal 100 where the location information is confirmed at the request of the administrator terminal 70 The message is transmitted.

At this time, the monitoring server 200 receives the field acquisition information including the field operation state from the field terminal 100, and transmits the field acquisition information to the administrator terminal 70. The manager confirms the on-site operation status and determines whether the situation is terminated.

Alternatively, the monitoring server 200 may receive the operation information request signal including the identification code recorded in the identification tag 400 from the field terminal 100, (For example, the frequency of the motor, the temperature, the real time of the pressure of the pump, or the stored data) of the apparatus from the server 40 to the end point in real time.

Therefore, after the tag 400 of the device is tagged, the field terminal 100 receives the operation information of the device in real time, and the operation information initially outputted is updated in real time. Therefore, as the field supervisor receives the operation information of the device in real time, the information sharing with the operator terminal 80 of the subject field room can be realized in real time.

In addition, the monitoring server 200 selectively provides maintenance information in response to a request from the field terminal 100.

That is, the field terminal 100 requests the monitoring server 200 for maintenance information (for example, one or more of the previous repair or replacement work report, manual, drawing, document, video, and image) And receive.

Here, the monitoring server 200 transmits the operation information received from the operation information server 40 to the field terminal 100 to the app. The app includes items such that the operation information of the driving information server 40 can be output and the field acquisition information can be input. Preferably, the app includes an item check list and input and output items of measurement data do.

More preferably, the app includes a menu for requesting maintenance information and a menu (for example, a messenger) for sharing information between the administrator terminal and other field terminals.

When the monitoring server 200 receives an application to which the field acquisition information (for example, a check list during operation of the apparatus or on-site status information related to start / stop and maintenance) is received from the field terminal 100, And generates and stores a report that is set by combining the operation information of FIG.

To this end, the monitoring server 200 includes a database 300 for storing the operation information, the identification tag 400, the registration information of the field terminal 100, and the report including the field acquisition information received from the field terminal 100 ). The database is as shown in FIG.

Referring to FIG. 5, the database 300 includes a tag DB 310 storing device-specific identification codes, a driving DB 320 storing driving information classified in accordance with an identification code and a time history received from the device, A terminal DB 330 in which registration information (at least one of a telephone number, a field inspector, registered fingerprints and identification information) of the field terminal 100 is stored, field acquisition information received from the field terminal 100, A field DB 340 in which the generated report is stored, and a maintenance DB 350 in which maintenance information is stored.

The tag DB 310 stores an identification code recorded in the identification tag 400 attached to each device. The identification code is used as identification information for identifying the corresponding device in the field terminal 100 and the monitoring server 200, and for classifying and storing the information.

The operation DB 320 stores previous operation information received from the operation information server 40. [ The previous operation information includes measurement time information.

The terminal DB 330 includes at least one of a telephone number of the field terminal 100, personal information of a field inspector, fingerprints, and identification information, and the identification information is unique identification information assigned for each of the field terminals 100.

Here, the identification information of the field terminal and the identification code of the identification tag can be utilized as the authentication information.

That is, the monitoring server 200 identifies and proceeds to the authentication of the communication connection between the mobile server 500 and the field terminal 100 as the identification code stored in the identification tag 400. That is, the monitoring server 200 can perform separate authentication or user confirmation processes as identification codes set for each device.

The field DB 340 stores the report received from the field terminal 100. The report of the field terminal 100 includes the field acquisition information input in the field together with the operation information and the maintenance information.

The maintenance DB 350 stores maintenance information. Here, the maintenance information is at least one of a previous report, photograph, video, document, drawing and manual relating to the replacement or maintenance of each device.

The on-site terminal 100 is a portable terminal that can be used while the on-site inspector is on the move, for example, a tablet PC, a smart phone, a PDP, or a PDA. A specific configuration will be described with reference to Fig.

The alarm module 122 issues an alarm as at least one of voice, light emission, and characters according to whether the error detection module 123 detects an error, generates an error occurrence message, and transmits the alarm occurrence message to the monitoring server 200, A text message is sent to at least one of the administrator terminal 70 and the other field terminals 100.

The fingerprint recognition module 124 detects whether the fingerprint stored in the storage unit 160 matches the fingerprint input through the terminal display 130 and outputs the result to the information output module 121. The information output module 121 outputs the operation information received from the monitoring server 200 to the terminal display 130 only when the fingerprint recognition result of the fingerprint recognition module 124 is matched.

The input module 125 inputs the field acquisition information input through the terminal display 130 to the app. At this time, the field acquisition information input may include one or more of photographs, moving images, and data.

The security module 126 deletes the maintenance information and / or the operation information and the site acquisition information output to the terminal display 130 according to the set deletion condition. Here, the deletion condition is set to one or more of whether the other identification code is received or booted, the delete instruction of the security terminal, and the setup time after the information is output to the current terminal display 130.

Also, when a command to store the operation information and the scene acquisition information output to the terminal display 130 is input, the security module 126 provides the security code and stores the security code as a set file. Here, the security code information is transmitted to the security terminal 600 through the security communication unit 170.

More preferably, the security module 126 determines whether a security code has been assigned to the security terminal 600 when a predetermined time has elapsed to prevent leakage of the information of the power plant equipment to the outside by mistake of the field installer, Forcibly delete the saved file.

The location information module 127 transmits current location information to the mobile server 500 in real time. The location information transmission of the on-site terminal 100 may be performed by searching the on-site terminal 100 adjacent to the on-site terminal 100 and transmitting a confirmation message when a maintenance situation occurs in which the apparatus is stopped during operation.

In other words, the present invention has an advantage that it is possible to confirm the location information of the on-site inspectors for maintenance of the apparatus installed in the power plant in real time, and to cope promptly when an emergency occurs.

The terminal communication unit 140 receives the operation information from the monitoring server 200 under the control of the terminal control unit 110 and transmits the site acquisition information inputted by the input module 125 to the monitoring server 200.

The tag reader unit 150 receives the identification code and / or the URL information through short-range wireless communication with the identification tag 400. The received identification code and / or URL information is output to the terminal control unit 110.

The storage unit 160 stores a file in which the security code is set by the storage command and a history of the deleted information.

In the case of the valve opening / closing detection sensor, there is a technique of detecting when the valve is rotated to the open position or the closing position, or detecting whether the valve is opened or closed by making the electric signal (or electromagnet) And the like. The valve opening / closing detection sensor may be applied to any device that senses opening / closing of a valve by applying a known technique other than the above-described.

An identification code capable of identifying the device and / or the system is set in the signal conversion module 712. The signal conversion module 712 converts the detection signal received from the sensor module 711 into a signal according to the communication protocol, And outputs it to the module 713.

The wireless communication module 713 transmits the sensing signal output from the signal conversion module 712 and the sensor sensing signal including the identification code to the driver terminal 80.

The driver terminal 80 receives the sensing signal received by the wireless sensor 710 and outputs it to the display. To this end, the operator terminal 80 may include a separate database including an identification code and device and / or system information (e.g., name and location) so that the identification code assigned for each wireless sensor 710 can be identified have.

Here, the driver terminal 80 is a main control room terminal that controls start and stop of each device. That is, the operator of the main control room can check the status of each device and the system generated in the commissioning process from the wireless sensor 710 in real time.

More preferably, the driver terminal 80 is directly connected to the trial operation wireless receiver 720 via a LAN so as to receive the wireless detection signal without passing through the test operation relay server 730.

The present invention includes the above-described configuration, and a method of managing a power plant using the Internet of objects according to the present invention will be described below.

FIG. 9 is a flowchart illustrating a method of managing a power plant using the Internet of objects according to the present invention.

Referring to FIG. 9, a method of managing a power plant using the Internet using the Internet according to the present invention includes registering a monitoring server 200 that registers information of a field terminal 100 of a site inspector and an identification tag 400 attached to each device The wireless connection step S200 of the field terminal 100 that transmits the site acquisition information to the monitoring server 200 online and the wireless connection step S200 of wired connection with the monitoring server 200 to transmit the site acquisition information A wired connection step (S300), and an information security step (S400) for deleting the reception and storage information of the field terminal (100).

The registration step S100 of the monitoring server 200 is a step of registering the field terminal 100, the identification tag 400 and the device information. The field terminal 100 registration information includes personal information of a user (field supervisor) of the field terminal 100, a telephone number, and a unique code including the transmitted application. As the registration information of the identification tag 400, the identification code of the identification tag 400 installed for each device is registered.

The monitoring server 200 stores the information of the field terminal 100 in the terminal DB 330 and the identification tag 400 information in the tag DB 310.

In addition, the monitoring server 200 is configured to classify and store the classified operation information in the operation DB 320, which stores the operation information received from each device to which the identification tag 400 is attached, according to the identification code, Create and save apps that include as items. The field DB 340 is classified into a unique code assigned to each field terminal 100 and includes a date and time, an identification code (device name), a report name, and whether an error has occurred.

In addition, the registration step S100 of the monitoring server 200 generates an app for each of the identification codes, which is capable of outputting the operation information and inputting the site acquisition information, to the registered site terminal 100, And is stored in the operation DB 320 together with the history information.

In addition, the registration information of the field terminal 100 includes fingerprints, personal information, and unique identification information of the field inspectors. Such fingerprint recognition is intended to prevent the leakage of information by a person other than the registered field inspectors.

In the wireless connection step S200, the field terminal 100 inputs the site acquisition information confirmed in the field to the operation information received from the monitoring server 200 through the relay of the mobile server 500 and transmits it to the monitoring server 200 . Here, the operation information is received in real time after the field terminal 100 tags the identification tag 400. Therefore, the field supervisor receives the operation information of the corresponding device in real time from the field terminal after tagging the identification tag.

In the wired connection step S300, the field terminal 100 and the monitoring server 200 are connected to the monitoring network 20, which is composed of a wired cable, and compares the operation information with the site acquisition information, This is the step of generating the field surveillance report.

The wired connection step S300 is performed by tagging the identification tag 400 after the field terminal 100 is fastened to the connector 21 connected to the cable extended to the site where the device is installed and receives the operation information from the monitoring server 200 , And then transmits to the monitoring server 200 a report in which the input site acquisition information and the operation information are combined.

At this time, if the wired cable is not connected from the wired connection step (S300) to the site, the field terminal acquires the site acquisition information, moves to the location where the monitoring server 200 is located, And can be connected directly to wired and wireless. The direct connection step (S310) between the field terminal and the monitoring server 200 will be described later with reference to FIG.

In the wired connection step S300 and the wireless connection step S200, the operation information server 40 collects the operation information for each device connected to the control network 50 in real time and transmits the operation information to the monitoring server 200, (Not shown).

The information security step S400 is a step of deleting the operation information received in the field terminal 100 when the deletion condition set in order to prevent information leakage in the wireless connection step S200 and the wired connection step S300 is satisfied. This will be described with reference to Figs. 12 and 13 as a first embodiment and a second embodiment.

10 is a flowchart showing the wireless connection step of the present invention.

10, the wireless connection step S200 of the field terminal 100 includes a location information transmission step S210 for transmitting location information in real time, a message reception step for receiving and outputting a message from the monitoring server 200 An identification code receiving step S230 for receiving an identification code for each device from the identification tag 400, an operation information receiving step S240 for requesting and receiving the operation information including the identification code, (S250) for inputting the site acquisition information into the site acquisition information (S250), a transmission step (S260) for transmitting the site acquisition information including the occurrence of an error, and a maintenance In the information selection determination step S270 and the maintenance information selection determination step, when the maintenance information request command is input, the maintenance information request step S280 of requesting maintenance information to the monitoring server 200 .

The position information transmission step (S210) is a step of transmitting position information in real time under the control of the terminal control unit (110). The location information module 127 transmits the location information to the monitoring server 200 in real time under the control of the terminal control unit 110.

Therefore, the monitoring server 200 can check the current position of the plurality of the field terminals 100 in real time, and can call the nearby field terminal 100 when the maintenance related situation occurs through the location information.

The message receiving step S220 is a step in which the terminal control unit 110 receives a message through the terminal communication unit 140 and outputs the received message to the terminal display 130. [ Here, the terminal display 130 outputs a message including a check or repair command (for example, repair of the pump) of the device received from the monitoring server 200. [

The identification code transmission step S230 is a step in which the terminal control unit 110 transmits the identification code received from the tag reader unit 150 to the monitoring server 200 and requests the operation information of the corresponding device.

The operation information receiving step S240 is a step in which the terminal control unit 110 receives the operation information from the monitoring server 200 and outputs the received operation information to the terminal display 130. [

The monitoring server 200 confirms the identification code received from the field terminal and transmits the operation information of the corresponding device transmitted in real time from the operation information server to the field terminal 100 in real time.

Here, the operation information is transmitted as an app. At this time, the application displays an input item according to the identification code of each device, and the monitoring server 200 inputs the data included in the operation information according to the items displayed in the application and transmits the data to the field terminal 100.

Alternatively, the application may also store the operation information received from the monitoring server 200 by itself in the field terminal 100, and output the inputted operation information. That is, the app may be received from the monitoring server 200 or stored in the field terminal 100 itself.

Hereinafter, an embodiment of receiving an app including operation information from the monitoring server 200 will be mainly described, but the present invention is not limited thereto.

One example of the operation information received from the monitoring server 200 is shown in FIG. 14 to FIG.

14 is a screen showing an application related to start / stop, and FIGS. 15 to 17 are screens showing an application for inputting on-site monitoring of the operation state of the device.

First, referring to FIG. 14, the operation information related to start / stop includes, for example, a pre-activation confirmation field 131a, a post-activation field confirmation 131d, And a selection menu 131c.

Of these, the field check items before the start of operation and the field check items after start are checked by the field inspector on the site to check whether there is any abnormality by each item (for example, oil leakage, temperature, noise and pressure) The status information is displayed on the monitoring server 200 as measurement information collected from the apparatus.

Accordingly, the field terminal 100 receives the operation information including the state information of the apparatus in real time. At this time, confirmation items on the field prior to the start of operation and on-site confirmation items after the start-up are blank and the abnormality is not checked.

If it is a field monitoring report state during normal operation of the apparatus, the monitoring server 200 transmits an app including items related to field monitoring and operation information as shown in Figs. 15 to 17.

That is, if the identification tag 400 received from the field terminal 100 is associated with the pump, the monitoring server 200 transmits the measurement data of the pump received from the operation information server after the time when the identification code is received, To the field terminal 100 via the app of Fig.

15 is a view showing the main app that outputs the operation information of the monitoring server 200, input of the site acquisition information for the accessory device and the connection structure for determining the operation state of the pump,

Here, the operation information includes state information of the accessory device according to the operating state of the pump 31. [ For example, as shown in Fig. 16, the diagram and data showing the pressure state of the piping and the valve of the pump may include the pressure at the outlet side of the pump 31, as shown in Fig. 17. [ And the pressure of the valve are updated in real time as they are received in real time from the operation information server.

Each of the apps includes a field acquisition information input field 131a for allowing the field supervisor to input site acquisition information confirmed at the site, And an information output window 132b.

In the field acquisition information input step S250, the terminal control unit 110 controls the input module 125 when an input command is received through the application screen output to the terminal display 130, And inputting information.

For example, the field inspectors compare the state information of the device included in the operation information with the field conditions to check whether there is an abnormality in the field confirmation items before the start and / or the field confirmation items after the start. At this time, the terminal control unit 110 drives the input module 125 in accordance with the selection command of the site inspector, and inputs the site acquisition information to the application screen.

Preferably, the above-described app may further include an input and / or selection menu 131e for inputting detailed information of the situation in order to input confirmation information of the field inspector.

Alternatively, the site acquisition information is a value inputted by confirming the indication value of the pressure indicator in the field, as shown in Fig. 17, for the site monitoring report.

Here, the operation information of the monitoring server 200 includes measurement data of the outlet-side pressure of the pump. This is the measured data from the pressure measuring device installed in the pump and the pressure value measured after the time when the identification code is received is output in real time.

In the transmission step S260, when the terminal control unit 110 receives the transmission instruction after inputting the site acquisition information, the terminal control unit 110 transmits the site acquisition information combined with the above-described operation information to the monitoring server 200 through the terminal communication unit 140 . Here, the present invention alerts the user whether or not an error has occurred by comparing the on-site confirmation data (for example, an indicator value of the indicator) with the same item as the measurement data of the status information 131b.

That is, when the field acquisition information is input by the input module 125, the terminal control unit 110 controls the error detection module 123 to compare the operation information with the field acquisition information, and if an error exceeding the set error range is generated And outputs an error occurrence signal to the alarm module 122.

Accordingly, the alarm module 122 alerts an error as one of voice, text, and light emission signals, and more preferably, generates a message including whether an error has occurred and transmits the message to the monitoring server 200 and / or the set administrator terminal and / The other field terminal 100, the driver terminal 80 of the main control room, and the like.

Alternatively, the terminal control unit 110 transmits to the monitoring server 200 whether or not an error has occurred in the combined application of the operation information and the site acquisition information (hereinafter, the site report).

Then, the monitoring server 200 confirms the received field report and transmits it to the manager terminal 70, and the manager confirms whether the field report is to be terminated, and transmits it to the field terminal 100.

Accordingly, the field installer receives the received status termination message to the field terminal 100, ends the current situation, and prepares for the next situation.

In the maintenance information selection decision step S270, the terminal control unit 110 determines whether a maintenance information selection command is input through the input module 125. [

In the maintenance information request and reception step S280, when the terminal control unit 110 receives the maintenance selection command from the input module 125, the terminal control unit 110 controls the terminal communication unit 140 to request the monitoring server 200 for maintenance information And receives and displays it on the terminal display 130.

In other words, the field terminal 100 can use the maintenance information including at least one of manuals, drawings, images, moving pictures, and manuals that can confirm the maintenance status of the device as an identification code Can be requested with an identification code.

This operation is the same as the above-described operation of receiving the identification code of the field terminal (S230), the operation information receiving step (S240) of requesting and receiving the operation information including the identification code, the scene acquisition information input step (S250), and a transmission step (S260) of transmitting the field acquisition information including the occurrence of an error.

That is, according to the present invention, the field supervisor receives operational information and maintenance information related to the start / stop of the device through the tablet PC, and can share information between the field supervisor and the operator of the main field by comparing them in the field.

In particular, since the field terminal 100 is transmitted in real time from the operation information server 40, the operation information of the corresponding device 30 is output in real time after the identification tag 400 is tagged.

Alternatively, the monitoring server 200 stores the real time and / or previous operation information received from the driving information server 40 in the driving DB 320 of the database 300 together with the measured time history. Therefore, the field terminal 100 can request and receive not only the current operation information measured in real time but also the operation information of the previous time as an identification code. This can be arbitrarily selected from among the receiving step and transmitting step (S240 to S260) of the identification code as described above.

In addition, the present invention preferably includes a fingerprint recognition process for information security. This can be included in the entire process as well as the maintenance reporting step described above.

For example, when the identification code is received or the operation information is received from the monitoring server 200, the terminal control unit 110 drives the fingerprint recognition module 124 to request a fingerprint of the field inspector.

Accordingly, the fingerprint recognition module 124 outputs the fingerprint input window through the terminal display 130, and when the fingerprint is inputted, the monitoring server 200 requests the inquiry about the fingerprint.

Therefore, when the fingerprint search request signal is received through the relay of the mobile server 500, the monitoring server 200 checks the unique code of the corresponding field terminal 100. Here, the unique code of the field terminal 100 is received together with the fingerprint search request signal. Then, the monitoring server 200 compares the fingerprint classified into the unique code matched to the terminal DB 330 and transmits the result to the field terminal 100.

The fingerprint recognition module 124 outputs the fingerprint recognition result received from the monitoring server 200 to the information output module 121 and the information output module 121 confirms the result and outputs the operation information to the terminal display 130 Output.

Preferably, the fingerprint recognition process is performed prior to the reception of the driving information, and if there is no tagging of the identification tag 400 for a set time after the first fingerprint is recognized, or if a reboot, It is also possible to proceed after turning off the screen of FIG.

Alternatively, the fingerprint recognition process may proceed whenever the identification code is received or tagged to the identification tag 400. [ Such a fingerprint recognition process is not limited to the above-described embodiments, as various options can be selected by a business operator or a designer.

11 is a flowchart showing a direct connection step between a field terminal and a monitoring server in the wired connection step of the present invention.

11, the direct connection step S311 includes an identification code receiving step S311 of the field terminal 100 receiving the identification code, a field terminal (Step S312), an identification code of the monitoring server 200 and a field acquisition information receiving step (step S313), and a step of searching and retrieving the operation information collected at a time corresponding to the reception time of the identification code (S315) of the monitoring server (200), and a report generating step (S315) of the monitoring server (200) that automatically generates a report by combining the operation information and the site acquisition information.

The identification code receiving step S311 of the field terminal 100 is a step in which the field terminal 100 recognizes the identification tag 400 attached to each device and receives the identification code recorded in the identification tag 400. [

When receiving the identification code, the terminal control unit 110 of the field terminal 100 transmits an application to the terminal display 130 through the information output module 121, .

The information storage step S312 of the field terminal 100 is a step of storing the field acquisition information in the field terminal 100 and storing it in the app. Here, the terminal control unit 110 drives the input module 125 to input the input site acquisition information to the app, and then stores it in the storage unit 160. At this time, information to be inputted may be text, photograph, moving picture and image.

The information receiving step S313 of the monitoring server 200 is a step of receiving, from the monitoring server 200, field acquisition information from the field terminal 100 via wireless or wire. After inputting the site acquisition information, the site inspector moves to the location where the monitoring server 200 is located and is directly connected to the monitoring server through a wired cable (for example, USB) or wireless communication (Wi-Fi and / or data communication) And acquires the acquired information. At this time, the site acquisition information received by the monitoring server 200 includes an identification code and a time.

The operation information searching and calling step (S314) of the monitoring server 200 searches for and recalls operation information collected in the matching time zone from among the operation information of the device matching the identification code and time received from the monitoring server 200 to be.

Here, the monitoring server 200 checks the time recognized by the identification tag 400 (for example, the reception time of the identification tag 400 in the field terminal 100) Search and invoke the collected operation information.

The report generation and storage step (S315) of the monitoring server 200 is a step of automatically generating and storing a report by combining the site acquisition information and the operation information in the monitoring server 200. [ The monitoring server 200 automatically generates and stores a report by combining the site acquisition information and the operation information in a predetermined manner. The stored report is stored in the field DB 340 of the database 300. As shown in FIG. 14 to FIG. 17, it is preferable that the report is generated as an app including at least one of items, abnormality, and measurement data.

As described above, the present invention can be applied to an embodiment in which the field terminal 100 and the monitoring server 200 are connected through the relaying of the mobile server 500 through the wired network, and between the field terminal and the monitoring server It is very easy to generate reports for on-site monitoring and maintenance through direct connected embodiments.

In addition, the present invention further includes an information security step (S400) to prevent information leakage in the wireless and wired connection steps (S200, S300) and direct connection step (S310). The first embodiment (S410) of the dual information security step (S400) will be described with reference to FIG. 12, and the second embodiment (S420) will be described with reference to FIG. The first embodiment is an embodiment for information security in a wireless and wired connection step, and the second embodiment is an embodiment for information security in a direct connection step between a field terminal and a monitoring server.

12 is a flowchart showing a first embodiment of the information security step of the present invention.

Referring to FIG. 12, a first embodiment S410 of the information security step of the present invention includes an information output step S411 of outputting field acquisition information and driving information, a new information determination A step S412 of determining whether a set time has elapsed after the operation information is received, and a step S413 of determining whether the new ID code has been received or the information output to the terminal display 130 when the set time has elapsed (S414), and a history information generating step S415 for generating a deletion history after the information deletion step S416.

The information output step S411 is a step in which at least one of the field acquisition information and the operation information is output to the terminal display 130. [ Here, the terminal control unit 110 drives the information output module 121 and the security module 126 when the initial identification code is received.

The new information determination step S412 is a step of determining whether the field acquisition information and / or the operation information of the other device is output after the application is executed on the terminal display 130. [ Preferably, the security module 126 determines whether another identification code is received or an on-site report is sent after the initial identification code is received.

The set time determination step S413 is a step for determining whether the set time is exceeded by counting the time since the information is outputted to the terminal display 130 in the security module.

For example, the security module 126 may cause the terminal display 130 to count the time after the operation information is received when the site acquisition information and the operation information for monitoring the operation state of the pump are output, The time is counted to determine whether the set time has elapsed.

The information deleting step S414 is a step of deleting the information output to the terminal display 130 when the deletion condition (new information and / or time) set in the security module 126 is satisfied.

For example, when the new identification code is received in the situation where the field acquisition information and / or the operation information is output based on the previous identification code on the current terminal display 130, the security module 126 outputs the information . Alternatively, the security module 126 may confirm whether the site report is transmitted to the monitoring server 200, and delete the information.

Alternatively, if the security module 126 has reached the set time by counting the time at which the device identification code was received, the time at which the operation information was received, or the time after execution of the application, .

In addition, the deletion condition may include whether the field terminal 100 is booted and whether the security terminal 600 is forced to delete it. For example, the security module 126 deletes all previous information when the field terminal 100 is rebooted. The forced deletion instruction by the secure terminal 600 will be described with reference to the second embodiment.

The history information generating step S415 is a step of generating and storing the deletion history information. The security module 126 generates a history (e.g., identification code and time) of the deleted information.

The deletion conditions of such information can be variously set according to the choice of the operator or the designer. More preferably, the first embodiment of the information security step S400 is applied in the wireless connection step described above.

13 is a flowchart showing a second embodiment of the information security step of the present invention.

Referring to FIG. 13, the second embodiment S420 of the information security step may include an information output step S421 of outputting information to the terminal display 130 and a determination of whether or not a storage command is input in the information output step S421 A security code generation and storage step S423 for generating a security code when a storage command is input; an information deletion determination step S424 for determining whether the security code corresponds to a set deletion condition; And an information deletion step (S425) of deleting the information if the condition is met.

The information output step S421 is a step of outputting the site acquisition information through the application executed in the off-line state of the field terminal 100. [ Here, the terminal control unit 110 drives the security module 126 to control the information security process in the offline state when the identification code is received.

The storage command determination step S422 determines whether a storage command of the application output to the terminal display 130 is input. In this case, since the field inspectors do not receive the operation information from the monitoring server 200 in real time, the field inspectors input the field-by-apparatus acquisition information and store them in the field terminal 100, and then directly connect to the monitoring server 200 It goes through. Accordingly, the terminal control unit 110 determines whether a store command is inputted in an off-line state.

In the security code generation and storage step S423, the terminal control unit 110 drives the security module 126 to store files, and generates and registers a security code for each file. Here, the security module 126 converts the application output to the terminal display 130 into a file, stores it in the storage unit 160, generates a security code for each storage file, and stores the generated security code in the storage unit 160. The security code includes the storage time of the file and the identification code of the device.

For example, the security communication unit 170 is installed in a short-range wireless tag, and the security module 126 records information capable of indicating whether or not the security code is stored in the security communication unit 170 immediately after the security code is generated It is possible.

Alternatively, the security module 126 sets the security code to the corresponding application unconditionally, irrespective of whether or not the information is stored, when the new operation information is received or the new site acquisition information is input.

The information deletion determination step (S424) is a step of determining whether or not the deletion condition is satisfied. Here, the deletion condition may be set according to the time, the security code, and the input and reception of new information.

The information deleting step S425 is a step of deleting the file stored under the control of the terminal control unit 110. [

The time-based deletion conditions include a time set after the file is stored, a time output from the terminal display 130 of the stored file, a time set from immediately after the operation information is received from the monitoring server 200, / RTI > and / or < / RTI >

Therefore, if the security module is in any one of the above time conditions, the security module deletes the storage file and updates the information recorded in the security communication unit 170. [

Alternatively, the security module 126 deletes the previous selection file if another file is selected after any one of the storage files is executed.

Alternatively, when the forcible delete command is received from the security terminal 600, the security module 126 deletes the save file to which the security code is set.

Here, the security terminal 600 confirms the presence or absence of a storage file recorded in the security communication unit 170 and transmits a forced deletion command to the field terminal 100. [ For example, when the field inspectors go out of the home terminal 100 in a state where files are stored in the field terminal 100 or move to the vicinity of the security terminal 600, the security terminal 600 performs wireless communication with the security communication unit 170 And receives the file storage information (i.e., the presence or absence of the security code) recorded in the security communication unit 170. [ The security terminal 600 transmits a delete command to the field terminal 100 when the storage information of the file in which the security code is generated is confirmed in the field terminal 100. [

Accordingly, when the forcible delete command of the security terminal 600 is received, the terminal control unit 110 drives the alert module 122 to issue an alert and drives the security module 126. Therefore, the security module 126 deletes the whole storage file in which the security code is generated.

As described above, the present invention collects the site acquisition information and the operation information for each device through the monitoring network 20 of the power plant using the Internet, and can monitor the state before and after the operation and the operation state, and maintenance and repair are easy.

In addition, the present invention may further include a test run monitoring step of checking the test run check items of each equipment and / or the system in real time through the test run monitoring member 700 described above.

Here, the wireless sensor 710 is installed in the target device and / or system in the test operation, and senses characteristics corresponding to the test operation check item and transmits the wireless detection signal. The commissioning wireless receiver 720 transmits the wireless sensing signal received from the wireless sensor 710 to the commissioning relay server 730 and the commissioning relay server 730 transmits it to the driver terminal 80. [ Or directly from the commissioning radio receiver 720 to the operator terminal 80.

The driver terminal 80 receives the wireless detection signal received from the trial operation relay server 730 or the trial operation wireless receiver 720 and confirms the identification code assigned to the device and / or the system, Output the measurement data of the test run check item.

Accordingly, the operator can check the data output from the driver terminal 80 and check the test operation check item in real time.

In other words, the present invention can solve the troublesome problem that the operator has to acquire data directly in the field in order to acquire the data set as the inspection item in the trial operation.
