摘　　要：针对现代战场电磁环境恶劣、战场形势瞬息万变的特点,设计了一种通信设备,它采用基于ISDN的2B+D有线通信方式,具有较强的抗干扰能力;同时,该设备能够为每一批次的输入数据添加包号并记录时间信息,以便在数据输出时根据包号调取时间信息,从而计算出数据在其内部的时延,并将计算结果附于数据末尾,因此保证了通信的实时性。此外,使用脉冲测试方法对时延测算精度进行了测试,并给出了测试结果。实验表明,该设备具有很高的时延测算精度。This paper designed a system based on 2B＋D for the characters of severe electromagnetic environment and fast-varied situation of modern battle field. With the advantage of resistance to electromagnetic interference, it can also measure the time-delay. A pack number will be added and time information recorded when a frame of data received by this system. When a frame of data is transmitted by this system, the time information will be call to calculated time-delay result according to the pack number. The result will be adhered to the end of this frame. At last, we designed an experi- ment to test the performance of time-delay measuring. It proved that high accuracy this system has.
