Abstract
PCM data is result of air-vehicle flight test, this data is distributed for each engineers to analyze its condition. Since line-of-sight between the air-vehicle and the ground receiver cannot always be secured, remote PCM data recording system was claimed to be required. In this paper multi-function PCM data recorder has been described. This PCM data recorder was intended to place on inside of flight object. It can record about two hours in 32 GB SD card with maximum 7 Mbps data rate. RS-422/485 and RJ-45 interface enhanced accessibility for users. 5 V and 1 A power consumption and 19.5 mm × 152.5 mm × 102.3 mm allow to connect with mobile PCM devices. It acquired more than 190-minutes data in 12-times flight test. Also, it achieved military standard environmental test MIL-STD-810G to prove its stability and solidness.
PCM数据是飞行器飞行试验的结果，这些数据分发给各个工程师分析飞行器的状态。由于飞行器和地面接收器之间的视线不能总是得到保证，因此据称需要远程PCM数据记录系统。本文介绍了一种多功能PCM数据记录仪。这个PCM数据记录仪打算放在飞行物体的内部。它可以在32gb的SD卡上记录大约两个小时，最大数据速率为7mbps。RS-422/485和RJ-45接口增强了用户的可访问性。5v, 1a功耗，19.5 mm × 152.5 mm × 102.3 mm，可接移动PCM设备。在12次飞行试验中获得了190多分钟的数据。并通过了军用标准MIL-STD-810G环境试验，证明了其稳定性和坚固性。
