The method comprises: using bitstream-based message designing approach to divide a message into both message head and message body parts; using the object oriented design ideal to pack said message; said designed message comprising a MessageHead and a Messagebody; said message is packet into one message packet.

The invention relates to a data association method used for airplane digitalization maintenance and application. The association method includes: a first object digital model of information is obtained, wherein the first object digital model of the information is related to the first object digitalization maintenance and application; the first object digital model is stored; based on the information shown by the first object digital model, at least one part of the first object digital model is marked to be a hot area; and according to the information shown in the hot area, a corresponding second object digital model is confirmed, a data list is formed and contains corresponding relation between the confirmed hot area and the second object digital model which corresponds to the hot area, and the second object digital model contains information related to the airplane digitalization maintenance and application. By utilization of the data association method used for the airplane digitalization maintenance and application and a data association device used for the data association method used for the airplane digitalization maintenance and application, relevance and dynamic application between a maintenance manual and a three-dimensional digital model can be established, intuition of a maintenance process is strengthened, and the efficiency and quality of maintenance are improved.

The invention relates to an AX88180-based scientific-grade CCD Gigabit Ethernet communication system and method and the problem of loss of image data collected by equipment caused by communication congestion or even collapse in a 100-mega network in an existing image transmission system is solved. The system comprises a network communication circuit board and an FPGA circuit board. The FPGA circuit board comprises an FPGA chip, an EEPROM chip and an SDRAM chip. The FPGA chip and the EEPROM chip are connected according to an IIC protocol, and the SDRAM chip is connected to the FPGA chip for data storage. The network communication circuit board comprises an MAC layer chip, a PHY layer chip and an RJ-45 interface connected in sequence. The MAC layer chip is AX88180, and the PHY layer chip is88E1111. The data collected by the FPGA chip is transmitted to the MAC layer chip and the PHY layer chip and is transmitted a PC upper computer through the RJ-45 interface. The FPGA chip includes a network initialization module, a packet unpacking module, a network protocol module, a command parsing module, a control scheduling module and an EEPROM parameter access module. The invention also provides a method for realizing scientific-grade CCD Gigabit Ethernet communication based on the above system.

The present invention provides a hardware database-oriented development and display system and method, wherein the system includes: a user interaction module for receiving SQL, Java or C++ operation instructions; an SQL kernel module for obtaining SQL operation instructions, Call the SQL interface module to transmit SQL operation instructions to the hardware database, and return the operation results to the user interaction module; the Java kernel module is used to obtain Java operation instructions, call the JDBC interface module, and transfer Java operation instructions to the hardware database, and return the operation result to the user interaction module; the C++ kernel module is used to obtain the operation instruction of C++, call the ODBC interface module, transmit the operation instruction of C++ to the hardware database, and return the operation result to the user interaction module; the user The interactive module is also used to receive and display the operation result. Through the above solution, the difficulty of interacting with the hardware database system can be reduced.
