基于VC++的429信号发送接收设计

The Design of Transmitting and Receiving 429 Signal on VC++

随着国内航空业的发展,在许多航空机载设备的检测维修中出现了大量对429信号及其俄式标准的检测需求,这就使得对429信号的仿真和测试显得十分关键。本设计采用了虚拟仪器的设计思路,使用目前市场上技术成熟的基于PCI接口的429收发板卡,以VC6.0作为软件开发平台,在准备数据阶段根据俄罗斯标准编写32位双极性码数据,通过硬件和软件两方面设计实现了信号的发送接收设计,达到了使用个人电脑完成429信号检测任务的目的。

Because of the development of the national aviation industry, a new situation stands out in the work of aviation equipment testing and maintaining. The needs of check and measure the 429 signal and its Russian standard increased quickly which means that the key of the work is the 429 signal＇s simulating and testing, A way of virtual instrument based technology was introduced in this paper. This design used the 429 Transmit - Receive Board, which based on PCI bus and was mature in the market, as the hardware platform. And the software platform is the VC6.0. In the work of data preparation, the data was coded in the 32 bits bipolar code under Russian standard. The implement of signal transmitting and receiving which based on both of the hardware and software designs realized the aim of using personal computer to complete the work of checking and measuring the 429 signal.
