[31] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
[32] 1 is a block diagram of a corrosion monitoring and anticorrosive control system to which the present invention is applied.
[33] In the configuration, it controls the data transmission from the corrosion detection unit or the local corrosion monitoring unit (Local computer) installed in the field, and the data is converted into a database to display it graphically or numerically so that users can easily judge it. The central corrosion control system 100 having a main computer 210 for controlling the output to a printer, and receives a data collection command from each of the functional blocks inside the central corrosion control system, the location of the branch located in the field Detecting anticorrosive potential and making it into a database and transmitting it to the central corrosion control system through wired / wireless communication line 800, a plurality of corrosion detection units (400a to 400n), installed in a number of measurement places underground (500) Corrosion and corrosion protection of metal deposits and steel structures 700 is continuously detected and the values are transmitted to the central corrosion monitoring controller 100. It is used to manage the wire / wireless communication line 800, wide area network corrosion monitoring system or measurement location to be divided into several groups, and is located between the corrosion detection unit and the central corrosion control system. Storing the transmitted data, and transmits it to the central corrosion protection monitoring unit 100, and local corrosion monitoring control units (300a to 300n) for transmitting a command of the central corrosion protection monitoring unit to the corrosion detection unit, for measuring the potential potential Installed in the field as a sensor, consists of a method potential measurement unit 600 to select and use according to the environmental conditions.
[34] Looking at the action of the corrosion monitoring system configured as described above are as follows.
[35] First, when the central corrosion control system 100 and the corrosion detection units 400a to 400n are connected to each other using a wired / wireless communication line 800 such as a telephone line, a dedicated line, and wireless data communication, the central corrosion method is connected to each other through data communication. Anti-corrosion control unit 100 is operated by remotely controlling the corrosion detection units (400a ~ 400n), and receives the collected data in real time to compare and analyze the state of the metal structure to quickly and accurately show the value of various graphs In addition, it outputs an alarm when an abnormality such as over-formation or corrosion occurs, displays the location on a map, stores the collected data in a database, and diagnoses the corrosion-resistant state of metal structures using various statistical techniques based on this. After that, it has the function to print various graphs, figures, maps, corrosion state of metal structures, etc. The base / wireless communication line 800 is a communication line for data transmission between the local corrosion control unit and the central corrosion control unit 100 installed at each measurement location, and the central corrosion control unit 100 is collected. Based on the data, we will solve the existing difficulties in the management and analysis of the measurement error and the vast potential data, and reduce the measurement time, personnel, and the budget to achieve long life of maintenance and electrical installation facilities.
[36] In addition, the corrosion detection unit (400a ~ 400n) is an underground pipe (gas pipe, oil pipeline, water and sewage pipe, district heating pipe, etc.), oil refinery and petrochemical plant, hydro, thermal, nuclear power plant, refinery, It can be applied anywhere in the harbor and other metal structures, and transmits the current corrosion potential data read from the site to the local corrosion monitoring controller 300a to 300n in real time, which is basically performed by the local corrosion monitoring controller 300a to 300n. The function transmits the data received from the corrosion detector in real time to the central corrosion control system through wired / wireless communication lines.
[37] However, the most important of the functions of the local corrosion control system is that all functions of corrosion monitoring and method control performed by the central corrosion control system when the communication with the central corrosion control system are interrupted by various works, genius, accidents, etc. It has a built-in function to act.
[38] At this time, since the central corrosion control system can check the data received from the local corrosion control unit (300a ~ 300n) in real time, it is possible to quickly deal with any abnormality, and has an alarm storage and alarm function, the user is in the main control room Alternatively, the office can easily check the corrosion state of the entire anticorrosive object, and the anticorrosive current control unit 900 transmits the current anticorrosive current from the anticorrosive current supply device 1000 to the local corrosion monitoring and control unit 300a to 300n. It transmits through the line and receives the anticorrosive current through the data analysis device of the central corrosion control system and transmits it to the anticorrosive current supply device to control the anticorrosive current.
[39] 2 is a functional block diagram of an internal data analysis device of the central corrosion control system according to the present invention, which is a block configuration for controlling corrosion monitoring devices by receiving and analyzing corrosion potential data of corrosion monitoring devices installed in respective regions. It is also.
[40] Looking at the function according to the internal functional block configuration, the position registration unit 110a, the location name is currently installed the corrosion monitoring unit (400a ~ 400n), the ID number (collection unique number) of the device, and other related information The ID number is a very important function of setting the ID number as a reference number when storing continuously measured data in the field and when searching the stored data, which is an important standard for providing information on location registration.
[41] In addition, the period setting unit 110b is a function for setting a corresponding period when the entire data stored in a predetermined period or data of a desired period is to be represented by various graphs and numerical values. You can see the time zone and modify it to the desired time period in each graph.
[42] The next password changing unit 110c is used when the user wants to change to a separate password for “SACORM”, which is the initial password set to execute the program for the first time, and the collection start unit 110d is the corrosion detecting units installed at the measurement place. It is used to start receiving data from 400a to 400n, and the collection stopper 110e is used to stop receiving data from corrosion detection units 400a to 400n installed at the measurement location.
[43] The real-time potential graph plotting unit 110f for each position reads the transmission port and the measurement period set at the time of setting the environment and displays a change in the potential value currently measured from the corrosion detection units 400a to 400n installed on the site in a line graph. For example, the potential graph plotting unit 110g for each period is used when the change amount of the data stored for a predetermined period is represented by a line graph according to the desired measurement position and period so that the user can see the degree of potential change at the desired measurement location. The unit 110h allows the user to easily view the same time zone potential value according to the measurement position while moving the graph manually or automatically according to a desired position of the same time zone change amount of all data stored for a certain period of time.
[44] As described above, the period graph showing unit 110i, which shows the percentage (%) according to the potential distribution of the change amount of all the data stored in a certain period as a bar graph, allows the user to convert the corresponding percentage of the corrosion potential, the over corrosion potential, and the corrosion potential. The potential value plotting unit 110j for each period shows the data for any measurement position among all the data stored for a certain period of time as a numerical value and at the same time calculates the total number of data and the maximum, minimum and average values of the data. In order for the user to easily see the actual stored data value, the potential statistics unit 110k shows the stored corrosion data as the numerical value of the maximum value, the minimum value, and the average value in daily or monthly units for each measurement position, and statistical change The graph showing unit 110l displays the minimum, maximum, and average values for the measurement position selected by the user on a daily or monthly basis. Values are shown in a line graph to compare and analyze the corrosion mode potential progress of the various measurement points in the day and month, and the measurement position status unit 110m is actually installed in each of the corrosion detection units 400a to 400n. By displaying the location on the map, it is possible to easily grasp the entire distribution location, and to determine the current reception status of each location.
[45] Next, the alarm location list showing unit 110n displays the actual installed locations of the corrosion detection units 400a to 400n on a map so that the location can be easily identified, and also the current reception status of each location can be determined. And, the alarm occurrence list function unit 110o selects whether to add an alarm to the alarm list when the alarm occurs, the buzzer keeps ringing, and even if an alarm occurs, the user can select the buzzer ringing, and the output unit 110p. ) Outputs the real-time potential graph currently being received to the printer, and the anticorrosive current setting unit 110q automatically inputs the anticorrosive current amount based on the manual corrosion mode and also the current corrosion potential. There is an automatic mode for setting the following, and the following description (110-r) tells how to use the (On-Line) corrosion monitoring system.
[46] As described above, the corrosion protection system of the present invention can continuously and simultaneously measure data by monitoring the state of metal structures in real time and collecting various data in real time, and measure the collected data by database. Integrated management by location is possible, and the collected database can be analyzed to quickly and accurately determine the progress of the corrosion method of the metal structure, and alarms are issued to the measuring area where excessive or corrosion occurs. Allows immediate action on
[47] In addition, it saves the cost and labor cost of moving to the measuring area, and has the effect of preventing safety accidents caused by the measurement once installed in the dangerous area to measure.
