In order to improve the automation level of monitoring landing gear buffer, based on the old landing gear on the hardware platform, research and development and the improvement of the automatic acquisition and processing software buffer data. By using a wireless network mode, this system can pick-up, upload and storage the data collected by the sensor, real-time measurement and control when the shock absorber in the maximum displacement, the maximum static load, to build a new type of shock absorber data remote monitoring and management system. The main contents of landing gear test system are summarized as follows: (1) The complete structure of the real-time measuring system of shock absorber, including the overall: the acquisition terminal and computer software system. The hardware acquisition terminal is composed of a pressure sensor, displacement sensor, the temperature sensor; the software system includes data acquisition, processing, storage and curve display etc, by using the WI-FI wireless module for data transmission, wireless transmission between the device and computer data acquisition device. (2) Select the Visual Studio C# as the PC software development platform, adopting object-oriented modular design method, has carried on the corresponding function module design: The user management module, sensor module, data processing module, data display module, data query module. Among them, the data acquisition module using C# serial communication class operation of serial port equipment, improve the transmission accuracy of data, which makes programming convenient, simple and readable; Linear fitting by least square method, to measure the value and the actual value of the corresponding relationship between the sensor calibration; based on Client/Server, namely customer data management system / server mode, through the network database, the user can according to different query conditions see shock absorber during the test data and charts, realize the effective organization of sensor data and management. (3) On the system the basic function of the repeated test, the data obtained were processed and analysis, the obtained test results, comparing whether accord with the shock absorber in the compression process of the law. Data through the lower position machine gathering sensor exhibited good stability, the upper machine receiving, the data processing function is normal, can meet the application requirements.
