Line 1 has a very important guiding significance. This paper introduces a test system for generator detection of civil aviation aircraft, analyzes its system performance and working principle, and expounds the software design ideas and software functions of the whole system. The generator is the main accessory of the passenger aircraft engine. It is responsible for providing power for the instrumentation radar radio communication on the aircraft and the various control system aircraft illumination on the aircraft. As the main power supply system of the aircraft, 3-phase 400Hz, its load is mostly precision electronic devices, so its power supply quality must meet the standard. In the manufacture modification and overhaul of the aircraft, the generator part of the aircraft must be tested, and the parameters and performance indicators of the aircraft generator are required. The aircraft constant speed transmission unit 和6 and the integrated drive generator 03 are the main components of the generator. It is necessary to periodically or irregularly test the test equipment and test system, and to study the design and use of the aircraft to ensure that the aircraft is designed and used. Safe operation of the aircraft is necessary. 1 Test system working principle The test system is a multi-task information processing system that integrates data acquisition status detection work status analysis and fault diagnosis. The system is complex and the number of detected parameters is large. The working principle of the test system 1. Using the high-speed high-power motor to simulate the aircraft engine to drive the tested aircraft generator, it is required to measure the working parameters of the phase current line current phase voltage line voltage working frequency motor speed and the like in real time. At the same time, a set of load-loading system is designed to simulate the electrical equipment on the aircraft, and the generator is loaded under different conditions to record the working condition of the aircraft generator under different loads in real time. Although the test room in which the test system is placed adopts measures such as soundproof and shockproof ventilation, the high-voltage and high-current power lines are commonly found in industrial production sites due to the noise vibration of the generator during operation and the interference of various high-power electrical equipment to the power grid. The conditions are very bad. We use industrial control computers with strong anti-interference ability to improve the anti-interference ability and reliability of the system. The entire test system needs to detect current and voltage frequency, speed, etc. up to dozens of parameters. There are digital and analog quantities in these measured parameters. Various measured analog quantities are converted into 01 voltage signals by various sensors. The voltage signal is then transmitted to the computer through multiple 12-bit, six-pad optically isolated input and output in the computer. Various control signals and commands issued by the industrial computer are transmitted by the input and output boards. The whole computer system hardware constitutes the software design of the aircraft generator test equipment. The industrial control software is the software personnel on the control system hardware platform, through the programming means to realize the control interface and control algorithm. This kind of software has poor versatility and scalability, and it has a large workload and a long development cycle. The configuration software is a kind of monitoring platform software. With the configuration software, users can easily construct a control software system that suits their needs. The configuration software provides a good interpersonal interface, which can provide various shape parameter configuration interfaces, which makes the system functions easy to implement, which greatly speeds up the system development, simplifies the programming work, and the system maintenance is simple. We chose Kingview 5.0, which was launched by Beijing Asia Control Automation Software Co., Ltd. It is a kind of intelligent software package running on 486586 and other 0 machines. It uses Hujia, 398 Yang, Xinding Chinese operating system as its operating platform. Kingview 5.0 makes full use of the heart, 3-shaped function, good interface, easy to learn and use. The Kingview 5.0 system consists of two major components. That is, the software development environment engineering manager and the software running environment TOUCHVEW are composed of two parts, among which, the project manager has a built-in screen development system. The project manager and the Ding 01 are each independent paste application, which can be used separately; the two are interdependent, and the screen application designed and developed in the project manager's screen development system must be in the TOUCHVEW runtime environment. Can run. The goal of the software design idea system is to develop test equipment for the fixed-speed transmission of civil aircraft, 30 and integrated drive generator 6 for maintenance. The system has high requirements on the precision measurement accuracy of the measured parameters and the stability and reliability of the sensitivity system. When designing the software, the system is fully considered to construct an effective monitoring and data acquisition software and hardware platform system. Directly control the system on site, and strive to test and control the scene with clear and accurate picture description. The whole system status and parameters are monitored to realize data collection and equipment status of various parameters during the test. If a certain link in the system is out of adjustment or fails, the test equipment will have irreparable damage. Therefore, it is required to perform real-time detection on the operating status of the system, and find that there is an emergency when it is abnormal, and it has effective self-diagnosis and fault tolerance. Capabilities, ie accident prediction and fault diagnosis, are strong. Taking into account the level of the operator, the operation and use of the entire software system is as simple as possible, and the intuitive operation of the human-machine interface is simple. Operation is safe. Security protection is the application system can not ignore the use of permission to allow or prohibit it from operating the system. Selection of software function parameters Some parameters of the system operation can be displayed on the corresponding screen. The operator refers to the test regulations and selects and sets them according to the test requirements. On-site data collection and online monitoring and control provide a real-time database for monitoring production process data. Data is collected from the control field in textual analog or digital form, and data and status acquisition and processing are completed. The data display part of the development of the display, the completion of the data, including the analog digital trend history curve display function. The processing of data is divided into direct data dynamic real-time curve display historical data storage, datagram. System parameters and data are displayed in a predetermined format at any runtime. Drawing various characteristic curves, using the measured parameters, drawing various characteristic curves of the starting and generating single machine, can have an understanding of the running state and adjustment direction of the generator. Filter filtering is a technical measure to improve signal reliability during the detection process. Interference caused by various reasons cannot be completely eliminated by hardware measures. Appropriate filtering methods in the data will achieve better anti-interference effects. The print report function is rotated 180 degrees horizontally and rotated 270 degrees clockwise. The code is similar to the steps. Just replace the original statement in step 3 with the following statement. After the shape design is completed, how to save the shape? We analyze the 6-file save format and use the method of saving each object. The specific implementation method is to first save the object's class name, and then save the class's properties, such as the object's cover, Top, Width, Height, and so on. When opening a file for loading, first create a new object based on the class name, and then set the properties of the object based on the properties stored in the file. For example, when we save a static text, we first save the class name of the static text and then save its properties. The following is the preservation process of Ding Xun 6136. Similarly, during the file loading process, we can correctly reload the originally created object into the current file by reading the color. 4 Conclusion component, which plays an important role in simulating industrial on-site production and enriching the system interface, so its reliability requirements are particularly high. Because the system uses object-oriented processing methods, in addition, the 61 5.0 development environment provides powerful support for custom components, so the program from development, debugging to program operation, the effect is good. Of course, the system still has to be improved, such as the optimized shape of the rotation algorithm and so on. This paper aims to provide a kind of ideas for the design of the configuration subsystem in the industrial configuration software, and lay a foundation for the development of the configuration software.

The operator presses the print button at any time, the software generates the actual value of all measured at this moment and the status list of the system operation, and the printer prints immediately. The accident prediction fault diagnosis continuously monitors the production process and alarms the abnormal link, enters the fault diagnosis system, and takes corresponding measures. The control function realizes the control of the detection process and the control of the input and output boards. Operational Security Designing multi-level security controls and access rights, operators must log in to their identity to gain operational rights. When the operator's authority is less than the access rights of the software, the operator cannot start the system software. Conclusion This test system has been run many times, with reliable performance and simple operation. The measured data truly reflects the actual performance index of the measured object and meets the expected functional requirements. It is an ideal test equipment for aircraft generator maintenance.
