摘　　要：介绍某航空产品发送的BMK遥测数据的格式及采集原理。由于传统方法不能准确地接收数据,针对其中存在的数据丢失等问题,提出了一种解决方法。该方法通过FPGA对接收到的BMK遥测信号进行时序重建,并在计算机中开辟大的空间进行存储,从而去除了信号在传输中的干扰,得到理想的信号。大量试验表明,该方法能够在10 m的传输电缆上可靠地采集数据。In this paper, the data acquisition theory and form of BMK telemetry sent by a certain avionic device are introduced. Aiming at the problem that. direct transfering data can not be received correctly, a new method of data acquisiton is proposed. The new design rebuilds the time order of BMK telemetry data received by FPGA, and establishes a large capacity for memorizing the data in the processor, so the jam on line of data transfer can be wiped off completely, and the ideal signals can be generated. The test results show that the BMK telemetry data can be reliably acquired on 10 m wireline by this method.
