Detailed Product Description: | Excellent ARINC429 software -Of ARINC429 Data Bus Analyzer (1) development background ARINC429 bus protocol is American Airlines Electronic Engineering Committee (Airlines, Engineering, Committee) in July 1977, and published and approved for use in the same month. Its full name is DITS of digital information transmission systems. The protocol standard specifies the requirements of the transmission of digital information between the avionics and related systems. ARINC429 widely used in advanced airliner, such as B-737, B757, B-767 Russian-made military aircraft use a similar technology. The corresponding standard HB6096-SZ-01. ARINC429 bus is a simple structure, stable performance, immunity to interference. The biggest advantage is high reliability, this is due to the non-centralized control, reliable transmission, error isolation. The ARINC429 characteristics are as follows: 1, transmission One-way. The information can only be output from the communications equipment to send mouth spread by the transfer bus interface of the needs of the information of other devices connected to it. But the information must not turn the clock back to the already required to send a message interface. Requires two-way transmission between the two communication devices, each direction, each with an independent transmission bus. 1553B bus BC, the tasks and risks of the dissemination of information is no longer focused. 2, the drive capability Each bus can connect no more than 20 receivers. Transmission of information have plenty of time to ensure that the equipment less. 3, the modulation method Bipolar zero status code the way. 4, the transmission rate Level of two tranches of high-speed working status bit rate is 100Kb / s. System slow state of the bit rate used in 12Kb / s ~ 14.5Kb / s, range. The selection of bit rate error range should be within 1%. High-speed and low speed transmission with a transmission on the bus. 5, synchronization The basic unit of transmission is the word, each word is 32. Bit synchronization information is carried in the bipolar NRZ signal waveform, word synchronization based on transmission during the same period at least four zero-level time interval basis, ie, after the interval followed by the word you want to send a starting point for The starting point for the new word. In accordance with the provisions of the ARING 429 bus, each word format (binary or two - decimal) 32 :1-8 is a label bit (LABEL). It marks the type of information included in this send word, what is the meaning of the code is transmitted. A such as sending the VHF information, the label for the octal number 030; DME data, then the label for the octal number 201. 9-10 source terminal identification (SDI). It indicates the source of information or information terminals, such as a control box tuning word to be sent to the three VHF transceiver, you need to mark the information terminal, the tuning word conveying to the VHF receiver. 11-28 or 29 data sets (Data Field), depending on the type of word can be identified as is 11 to 28 or 11-29. It represents is determined by the specific data. If the label is 030, 11 to 29 for frequency data, the use of BCD code data format, ascended the throne 11-29. 29-30 or 31 for the symbol status matrix (SSM), according to word type 29 or 30 to 31. It noted that the data features, such as the South, North, positive, negative, etc., or the state. VHF within 30-31 (BCD encoding). 32 for the parity bit (P), which is used to check the sent data is valid. The way to check is the sum of the 1-31 high number of bits (ie 1 number) is even, then 32 to "1". If an odd number, displayed as "0". Four zero cycle, it is to send each data symbol of isolation in order to send the next set of data. Communication control Files, data transmission using the command response protocol, the transmission of data for binary data word, and ISO5 alphabet characters two. The file structure is a file from 1 to 127 records, one record from 1 to 126 data words. 1, file, data transfer protocol Transmitter data to the data to be sent to the receiver, the transmitting apparatus through the transmission bus to send a request to send the initial word, the receiver to receive this initial word through another bus to "clear to send" the initial word In response, the receiver is ready to receive data. The transmitter receives this response, and sends the first record. 2, the transmission control word Transmission characters included in the initial word, the middle word and the end of the word, file transfer each word 30, 31, said word type, file transfer data for ISO5 number of letters and binary data word. The label of the file transfer application file, including the management of computer systems communicate with each other, such as priority control ability, it is necessary to allocate more than one label to the files in these applications. At present, the market standard software to meet the general ARINC429, ARINC429 software development representative is particularly important, ARINC429 Data BusAnalyzer, the Olympe technology developed is representative of ARINC429 software. (2) Software a) the development environment: OS: WinXP Development languages: C, + + b) Operating environment: Operating system: Win98/2000/XP/Win7. Memory size: 1G and above Hard disk space: 160G and above c) The main functions: Supported interfaces: PCI, cPCI / PXI, PC/104, PC/104-Plus, USB, etc. Man-machine interface: standardized, flexible and friendly. Automatically the ARINC429 in the search system board and connect back to the operating handle. ◆ trigger mode is set, you can set the transmit channel trigger mode, receive channels can also set the trigger mode. The trigger mode within the trigger and trigger two. Receive mode settings: set the query to receive mode and interrupt the receive mode, when set to interrupt the receive mode, you can also set up to receive the number of words before an interrupt is generated. ◆ to receive data processing: can be set to display to the list, or saved to a file, it can be displayed and saved. You can select the save directory. The list box: can be set to scroll automatically, whether to automatically clear the list, when set to automatically clear the list, more than how many lines can be set to automatically clear the list. ◆ Module Properties: You can display the currently selected module type, manufacturer, and the logical number. ◆ Set the transmit channel parameters Support for parameter settings, select the module to send channel set to allow / disable the channel, set the transmit baud rate, set the parity to set the frame interval, set the idle bit, edit, send data. ◆ set up to receive the channel parameters Support for all receive channels of the selected module parameter settings set to allow / ban channel, set the receiver baud rate, set the SDI filter, edit, Label filtering data. Start / Stop send / receive data, can also save the received data to a file, according to the date named. ◆ of ARINC429 data analysis capabilities Data can be loaded from the file, automatically resolve to the list, and then press the channel, alias, the data word to find shows, you can also search result export to a file, to prepare the other required. ◆ support multiple modules at the same time control the same system. |
