About refueling system:

Refueling system process

2007 China Oil and Air Force Institute of Technology has developed a set of co-operation control system for refueling fighters and at the same time this system will in some part of the promotion of the Air Force.

Refueling system is divided into two parts, fuel stored in the depot, filling out the market. Refueling, the fuel controller to start from the controller control information to field computers, field control computer to the depot computer request, after computer processing depot refueling system startup, will be transported to field depots to refuel aircraft, refueling finished , a fuel controller to send the end of the command, control computer through the field to send messages to stop the refueling depot.

1.2 Control System

System architecture diagram below, left for the depot, the right to field, depot field to receive some information, the provision of fuel, part of field to the issue of fuel oil tanks or instructions to stop refueling, refueling and refueling records information.

By the system architecture diagram can be seen outside the field and depot have a master computer to control some of the major oil depot inverter output and field communications, hardware mainly Advantech Industrial Computer, analog output and the inverter board. The main control field refueling aircraft, recording data, the main hardware Advantech Industrial Computer, Analog Input Card, and the fuel controller.

Software used HMIBuilder, between the field and depot using Ethernet communications, and Ethernet, we HMIBuilder integrated soft-bus technology, the use of soft-bus technology enables more powerful communications.

Software Design

In determining the hardware architecture, software programming is particularly important. The system of automatic control, data storage, communications and so on need to control the software. In accordance with the functional, the software screen is divided into general, data processing and communication in three parts.

2.1 Interface Display

In an automated system, the interface display, data processing, communications and other functions are important, there is no distinction points, but the interface shows a window system, we can see is the interface of the first part, so the interface shows a system for measuring an important criterion.

In the automation system, the interface shows that the first real response to the operation of the site, to see the software on the operation of the entire system is very well informed, and secondly to be beautiful. Seems to make people feel uncomfortable.

The interface of the system has two parts, one field of six refueling interface controller, and real-time display of the liquid storage tanks, pressure and flow. Second, the oil depot of the project show that the state of inverter.

2.2 Data Processing

Data processing of the system mainly includes signal filtering, data storage, data query, three functions.

Signal filtering - the system level, pressure and temperature signals subject to interference larger, less stable, we use filtering software to enable data stability.

Data storage - the process of refueling aircraft required to keep a record of filling time, filling the volume of duty, aircraft number and other information.

Data query - we need to do so in different ways through the complex inquiries, refueling time, on duty personnel, aircraft and so the needs of its Key words to look up to facilitate information analysis.

2.3 Communications

Communication is to achieve automatic control of the bridge. Out of the system between the field and the use of fiber-optic Ethernet depot, outside the field and fuel controller using RS232 communications.

HMIBuilder Field in the realization of communication between the depot and the use of soft-bus technology, simply set the IP, that is, the completion of communication, but also capable of delivering not only data, as well as pixel information.

Contains common HMIBuilder drive device driver, the system used in the board have Advantech PCL-818 and the PCI1720, HMIBuilder the PCL-818 and PCI1720 drivers tested and the speed UTILITY themselves as good communication.

Fuel controller is a dedicated controller, which contains the system-specific instructions, and we specifically developed for this product drive.

Control system characteristics

3.1 technologically advanced

Hardware platform is used in the Industrial Computer Advantech and board, specifically the development of anti-explosive fuel controller, software, powerful configuration software HMIBuilder. To achieve the perfect combination of hardware and software.

3.2 easy

The system only need to refuel when the credit card, enter the amount of fuel, aircraft number, the end of the end of your credit card.

Powerful 3.3

HMIBuilder with powerful database functionality, the system will be used in a compound in which the database query, we only need to input words can be made through the relational database of all information, unlike the general configuration software can only query by time.

Interfere with the larger hardware, we have adopted the function of filtering software to solve the interference problem.

3.4 easy to maintain

Soft HMIBuilder bus technology can be applied not only communication, but also can be used for maintenance, through the soft-bus technology, we can modify pixel distance, the script and so on, can not be amended only each other's IP, so that we in the remote maintenance when very convenient set up in the first IP, the remote machine and local machine will be the same.

3.5 communications capabilities

Communication systems to complete communication between two computers, computer and board, computers, and good fuel controller, HMIBuilder unique software bus technology, is the communication between different computer easier, faster, that is, only need to set up IP data transmission can be realized.

Produced 3.6 interface

The current configuration of software elements, in general, with a unified interface, when users find it easier to accept. But it also has its negative side. First, the graphics rendering process configuration, a large number of graphic element is not available in real-time attributes, and if a uniform set of attributes that are displayed, it will be inevitable to these attributes into the memory, potentially increase large burden on the system, if the graphic element in larger quantities would cause the system to run at a slower rate. Secondly, if the configuration of a unified interface, will lead to some elements of the special treatment, such as a transparent bitmap handling more complicated. If you want to cover all aspects, but also a problem user. HMIBuilder adopted a different approach, in HMIBuilder graphics package, providing more than 60 kinds of basic elements, these elements have their own unique attributes, basically to meet the needs of the user's configuration, when users need to be more the performance of high-level way, you can group elements, into a group of graphic elements as popular as the configuration software, with a unified property, at the same time, in which the various elements of the property itself is also maintained. This structured approach, and can bring about a unified interface to configure some of these issues.

3.7 unique distributed network architecture

Now, the configuration software at home and abroad, the network function is weak, the network management system is the development trend of software configuration. HMIBuilder configuration software to support distributed architecture, based on Industrial Ethernet, through the software bus technology, for easy configuration of network nodes, network redundancy. In the control layer, HMIBuilder the fieldbus as a focus for industrial customers in order to man-machine interface at the core, providing system-level solutions.

3.8 high-speed data retrieval support for big points

At present, the configuration software, regardless of analog, switch, or sub-equipment, all of the data used on a table. This design for a smaller amount of data is also more appropriate to the project, but when a larger amount of data, such as the 1024 points, or an unlimited point of the project, in the search will be more difficult. HMIBuilder different methods used, it facilities (ie stations) for the object, each device associated with the needs of analog, switch, that is, in HMIBuilder system, in accordance with the (points, type, points) do only a triple to the determination of a point. Although some red tape to do so, but the structure of benefits is clear. Moreover, for some industries, such as remote power, such a structure is in line with the use of habit. At present, a number of configuration software, although there are power version, but, strictly speaking, it is difficult to truly universal access to the power industry.

Large-capacity 3.9 Save historical data

The current configuration software is often embedded in a small database, or embedded in large databases, will be to increase the cost to the customer. Save HMIBuilder using a variety of methods, users are free to choose:

1. Variable automatically save Save a day to generate a document, how hard, how much data storage;
2. Save data sets in support of the Save 4G;
3. Save ODBC way: You can direct and large-scale database for data exchange, through the TCL script, the implementation of SQL statements to ODBC databases and flexible operation.
