Application of Intelligent Instrument in Thermal Power Plant

The computer monitoring system of the 10,000-ton citric acid project of Yixing Thermal Power Plant adopts the basic structure of “smart meter + RS485 network + computer configuration”, that is, the relatively independent and powerful smart meters undertake the physical quantity control and data collection tasks of the industrial site; The RS485 communication standard is adopted between the meters, and the RS485 network is formed by connecting only one pair of twisted pairs; and the RS485 network is connected with the configured upper industrial computer to form a complete set of industrial control system. The system consists of management, operation stations, instrument control rooms and industrial sites. The management and operation stations are composed of management computers, report printers, and UPS uninterruptible power supply (back-up power supply to the main equipment room); the instrument control room is composed of RS-485 communication network and AI series artificial intelligence industrial regulators and is systematically responsible for The monitoring, control of temperature, pressure, flow, and liquid level at various control points and measuring points during the production process, as well as collection and conversion of data points, alarm discrimination, recording, report generation, accident recall, etc.; industrial sites include Industrial equipment, primary instruments, and some secondary instruments installed on site are the executive parts of the entire production process.

System advantage High reliability bus open system. The system is a single loop decentralized control and open structure system. The increase or decrease of user points (AI meters) is arbitrary. It is not limited by the number of meters and the distance. The user can realize the convenient and flexible configuration. AI meter as the control unit in the system, use RS485 as the field communication bus, use simple and reliable self communication protocol, can realize 100% instrument operation function on the computer. The failure of the transmission unit will not harm the entire system and will only affect the local data at that time.

· Wide range of applications, reasonable design, and economical price This system can monitor and control the pressure, temperature, liquid level and flow of the entire network in the production process. It can also implement unified management of the load of the entire network, unified scheduling, and ensure the entire The security of the network system is flexible and easy to configure. The system can be configured by our company, or it can be configured by the user. In addition to the parameter adjustment function of the AI ​​series industrial regulators, which can be realized through the keys on the instrument panel, you can also select the "instrument parameter modification" on the computer to complete. Computer charts, report formats, report management, operator level management, data collection and management, trend display, system diagnostic information display, function selection, etc. can be configured by the unit's engineers. All the software is displayed in Chinese, so it is very simple to master the system configuration skills.

High degree of automation, can implement real-time scheduling After adopting this system, manual records or analog records can be banned, all of which are automatically completed by the computer, and various reports can be automatically generated according to the configuration contents. The degree of automation is high and the functions of the company are high. From the network computer, the competent department can understand the production situation in real time, as well as the conditions of the control points and detection points of various parameters in the production process. The abnormal phenomena that occur can be corrected immediately. For unexpected incidents on the network, the functional departments can also immediately identify the location of the accident and the cause of the accident and handle it in a timely manner to ensure the normal operation of the network.
Software section

Software Architecture The internal structure of the software can be divided into the following sections: data acquisition, data processing, parameter modification, and rights management.

Data Acquisition: The system collects real-time data such as set values ​​and measured values ​​from the lower instrument and stores it in the internal database of the system.
Data processing: The system extracts data from the historical database according to user requirements and completes the specified processing functions, including engineering conversion, historical data display, and historical curve rendering.
Parameter setting: The user realizes the parameter setting of the instrument through the upper computer.

Permissions function: The user defines the system's permission and operation password, and each management has different operation authority.

· User interface The system interface is the working platform for users to use the software. The user can complete all operations on the system through the visual interface. The user interface includes: menu system, status bar, window system.
Menu System: Users can implement various system functions by performing pull-down menus.
Status bar: Place shortcut buttons for users to conveniently and quickly call each main window.
Window System: The core content of the user interface is the basic platform for implementing various system functions. Including the data display, parameter modification, curve generation, alarm operation, including almost all system functions.
·Software function

Real-time data display: Various data of the on-site intelligent instrument are uploaded to the host computer through the field bus. The value of the measured object in the host computer will be reflected in the flow chart and single instrument window in the form of numerical values, curves, and bar graphs.

Historical data shows that various data in the process of system operation are collected and stored in the historical database. Users can freely recall any set of data from the historical database for analysis. Historical data can also be displayed in the form of trend curves. Users can understand the trend of certain physical quantities over time by using historical curves.

Graphical display: According to the needs of the system operation, the flow chart of 11 actual processes can be called up from the host computer at any time, so that the operating status of the system can be grasped in a more intuitive manner.

Data report printing: The software provides a variety of data reports according to user requirements, including ordinary daily reports, monthly reports, annual reports, cumulative flow reports, etc., which can be printed out at any time.

Data input and parameter modification: When the system is running, the user can input control information on the upper computer. The information is transmitted to the field smart meter through the field bus to control the operation of the field instrument.

Alarm processing: When the measured value of the field instrument deviates from the normal value, the field instrument will send an alarm message to the upper computer. Upon receiving the alarm signal, the upper computer will automatically give an alarm on the screen and update the alarm list.
Human-machine interface: Under normal circumstances, the management and monitoring of the on-site intelligent instrument are completed by the host computer in the control room. The operator sends monitoring instructions through the computer to complete the control and adjustment of the field instrument. At the same time, the measurement data and status information of the industrial site can also be obtained through a computer monitor.
Rights Management: Based on the security of system operation, the software can assign different levels of privileges to users at all levels. Permissions are assigned by the chief engineer and each level has its own authority to implement the corresponding software functions.
