Abstract
Power plant field monitoring system and method using a QR code in which, when a user photographs a QR code attached to a monitoring field and transmits the photographed QR code to a route server, the route server transmits matching information that matches the transmitted QR code, from among process values at the monitoring field which are collected by a main control server, to a user terminal.
Claims6
A power plant field monitoring system using a quick reference (QR) code, the power plant field monitoring system comprising:
- one or more power plant field monitoring units each comprising at least one sensor for sensing a process value of at least one monitoring field of a power plant and to which a QR code that includes an identification number and an access address of the at least one monitoring field is attached;
- a main control server configured to collect process information, which includes an identification number of a monitoring field and a process value sensed at the monitoring field, from the one or more power plant field monitoring units;
- a route server comprising a process database for receiving collected process information from the main control server and storing collected process information about all monitoring fields, and configured to extract process information, which matches request information received from a user terminal, from the process database and transmit the extracted process information to the user terminal;
- and
- the user terminal configured to capture an image of the QR code and transmit the request information to the route server and output the extracted matching process information transmitted from the route server,
- wherein the route server comprises:
- a process database configured to store process information about each monitoring field;
- a firewall configured to protect information in the process database;
- and
- a router unit connected to the process database and configured to receive the request information from the user terminal, extract the process information, which includes a process value that matches an identification number included in the received request information, from the process database, and transmit the extracted process information to the user terminal,
- wherein the route server is physically separate from, but connected to the main control server via a hardwire.

A power plant field monitoring method using a quick reference (QR) code, the power plant field monitoring method comprising:
- (a) generating a process database configured to store an identification number and a process value of a monitoring field for each of one or more monitoring fields of a power plant, which is performed by a route server;
- (b) receiving process information that includes an identification number and a process value of a monitoring field for each monitoring field from a main control server, and storing the process information in the process database, which are performed by the route server;
- (c) capturing an image of a QR code attached to the one or more monitoring fields, generating request information requesting the process value corresponding to the identification number included in the QR code from the route server, and transmitting the request information to the route server, which are performed by a user terminal;
- (d) extracting process information, which matches the request information, from the process database, and transmitting the extracted process information to the user terminal;
- (e) transmitting the identification number and the process value to the main control server, which is performed by a field monitoring unit which comprises at least one sensor for sensing a process value of the one or more monitoring fields ;
- and
- (f) receiving the process information from the main control server via a firewall configured to protect information in the process database, which is performed by the route server,
- wherein the route server is physically separate from, but connected to the main control server via a hardwire.
