Research Of Data Collect System For Cushion Package

Fragility is a parameter to measurement the packaging design is reasonable or not and also an important parameter of the influence of the package economy applicable design for a main factor, thus accurately measured fragility is very important meaning to improve the packaging design. The study design a multidimensional, fast data storage measurement system on basis of analysis the traditional methods of traditional impact testing measurement methods. This system is using two of two axis acceleration sensor consists of a 3D accelerometer as a data collection, which takes microcontroller as the central control chip, and through the DMA device for data transmission channels of direct data transfer and fast data storage.The main research contents have the following three aspects:First, understand the theoretical models of traditional impact testing measurement and the specific methods of measurement, and according to the packaging dynamics in the description about the fragility acceleration, to analysis the key factors in the packing of drop testing. Based on the traditional impact test of shock multi-freedom present complex data storage and rapid determination of data acquisition, data storage is a short time rapid development of equipment design.The second, according to the design scheme of multidimensional data acquisition, choose two ADXL250 biaxial acceleration sensors as data collection. Use AT89C55 microcontroller as central control chip, Use 8237A as a DMA channel data transmission realizing Collecting data after frequency-field device directly to the storage device of rapid storage.Finally, the paper completed quickly data storage system hardware circuit. Combined with the proposed system hardware circuit and software architecture and test process, and the corresponding software program, completed the data storage and PC communications rapid display treatment and fast as independent modules can be stored parts used alone.
