1. Analysis

Processing large-scale oil refinery is complete, large-scale fuel production - chemical raw materials-based businesses, many of its production facilities as a result of the application of the DCS, the high level of automation and engineering data of the devices have been incorporated into the CIMS system factory. However, water, electricity, gas and heating tank common engineering data, as well as data, data into the factory is an independent, still rely on summary statistics, not meet the requirements of modern management. In order to accurately and quickly grasp and take advantage of the whole plant information, production status of the balance of effective co-ordination management, optimize the allocation of resources to improve the economic efficiency of enterprises, it is necessary to establish a "refinery plant-wide data collection system of public works" will be relatively dispersed first focus on the measurement data to the center, do a good job in the material balance, and then through the optical fiber into the CIMS system factory.

The data acquisition system is the first phase of the project, the first three tank into the factory measurement data acquisition and measurement focus to center. The system uses a star topology network architecture, host computer installed in the refinery measurement center, the next-bit machines were installed in the A, B, C three tank, and tank mass flowmeter connected to the region. IPC has taken Advantech PC-industry and with large-screen monitor and printer, the next-bit machine HMITECH embedded human-machine interface systems, the host machine and the next bit can be used between the modem, Ethernet, wireless network connection, use of public telephone network, oil networks, wireless data transmission network.

The system software by the host computer system engineering and the next crew composed of two major systems engineering, software configuration used to achieve HMIBuilder. With user-friendly, real-time, and less manual intervention, the use of the advantages of easy and convenient. All modular software design methods, the completion of each module of a function, follow and comply with the principles of modern software design.

2. Host Computer System

The host PC using Advantech industrial PC, and are equipped with printers and large-screen monitor. Host Computer System Engineering The primary function of communication networks through the host computer and the next bit of data transmission between machines, as well as lower real-time machine data collection of treatment, including the database, the flow diagram shows that the historical trend charts and bar shaped graph also shows the data table and various statements required printouts. For the completion of the above features, the use of systems engineering HMIBuilder PC configuration software, to achieve the following six modules, the structure clearly.

(1) system configuration modules: mainly used for the completion of the entire sub-system control and scheduling functions.

(2) drawing process module: The main interface to complete the various work process flow chart and the corresponding changes in the display parameters. In order to intuitively respond to the production of factory plant and production processes at the operational status, so that managers do a variety of state and information at a glance, especially the design of the flow chart display and their corresponding function modules. Of the tank in accordance with the requirements of the actual process and the corresponding flow chart shows the changes in the parameters. The flow chart in the top right of each corresponding to a list of the important parameters of the current data, allowing display more intuitive, more accurate information easy to master.

(3) Rod of historical trends and shows: the realization of the historical trends in production and reproduction of the corresponding point in time coryneform table shows maps and data. Historical trends, through the display of production can have a comprehensive understanding of vertical. In the historical trend display, in order to adapt to different requirements, design show by day and month display, in order to more fully and accurately understand the history of production. Show the process, but also an increase of the corresponding time point on the bar graph and data table shows, in order to provide users with a variety of clear and intuitive choice, the use of more convenient.

(4) SCADA communication module: The completion of the establishment of communication links and data acquisition and transmission. Data collection and communication is the core of the system. Distributed control is HMIBuilder software features. It has a wide range of display and monitoring functions to ensure data accuracy and completeness. In data acquisition and communication, for each of the data collected for the accuracy and integrity of the testing, to ensure that the correct raw data. In the design of the structure of real-time database, used to stand, parameter types of classification criteria, and search through the hash algorithm, high-speed access, support for ultra-large-scale points. Historical database to support the ODBC interface, you can connect SQL Server, DB2, Oricle such as databases.

(5) statements print function modules: the completion of daily, on the 5th, as well as print statements.

(6) logic system settings: mainly used for the completion of the entire system a means of display settings and security settings. In the data acquisition and processing system to set up a two-tier security measures, the first level of confidentiality for the boot settings, only the system operators and managers of the machine to boot, which can effectively prevent the use of machines has nothing to do. Second-class system into the confidentiality, in order to enter the system, such as: data acquisition, curve shows that print statements must be kept confidential inspection of the Road only, otherwise the system will exit to a safe state until the date identification. This is only a small number of system-level management, decision-makers will be allowed to enter and effectively improve the security of the system.

3. Lower system

Under the system adopted HMITECH crew embedded computer: Arpex universal controller. It has a smaller, modular, combination, and strict standardization of work in the black box approach can be advantages and environment suited to the working conditions. Each tank using a universal controller Arpex as the next-bit machine, its main function is as follows: data acquisition, monitoring the state of the flowmeter; data processing, the flow meter data will be standardized; data communications, the data will be standardized sent to PC.

Arpex universal controller (Advance BOX PC) after a rigorous design. It has a powerful internal processor computing performance and rich peripheral interfaces. Open system architecture design and verification of industrial-grade design to meet the environmental diversity of industrial automation applications. Therefore, in this design concept to meet customer specific needs of industrial automation applications. For example, the performance of strong, sturdy, durable, stable platform for computing performance in a compact great industrial automation applications to enhance the convenience and comfort, to support customer demand universal Windows operating system and embedded systems XPE, bundled generic version of 300 points distributed configuration software. System block diagram shown in Figure 2:

The next main task of systems directly related to the first tank of the intelligent instrument interface, a variety of production data will be collected and treated according to a certain format; Another important task is to continuously monitor whether there are lines of communication to the host computer data transmission request, the information will be collected quickly and accurately Chuan-up crew. In addition, as the next-bit machine, in this system it is as a "black box" module, in a host computer and between production devices. Its greatest feature is a continuous uninterrupted operation of the system, and once that is running the boot does not require any human intervention. This determines not only from under the crew to ensure safe and reliable hardware, but also in software development from the high reliability, security, the guarantee of its normal continuous operation, but also so that the next-bit machine with a certain degree of fault self-diagnosis and self-recovery.
