摘要
对天线接口标准组织(AISG)协议下电调天线控制系统设备扫描算法的性质进行研究和定性,弥补了AISG协议的不足.通过对掩码位推进过程中天线设备数对扫描时间产生影响的分析,获得了算法优化方法,同时提出了基于B-1掩码推进的树形冲突分解算法.该算法根据AISG协议设备扫描算法的特点,合理编排掩码推进位数和推进步骤,平衡了扫描过程中产生的空闲周期数和冲突周期数这一对矛盾,使得在有效识别电调天线设备的同时获得较低的扫描时间开销.
The nature of scanning algorithm for remote electrical tilting antenna control system based on antenna interface standard group （AISG） protocol is investigated and determined, it is made up for the inadequate AISG protocol. The algorithm is optimized when considering the influence in which the anten- na device number is exerted on the scanning time during the process of increasing mask bits. Meanwhile, a tree collision splitting algorithm based on the B-1 mask-bit increasing is proposed. In accordance with the characteristics of the scanning algorithm for AISG protocol, this algorithm reasonably arranges the numbers and steps of increasing mask bits, and solves contradictions between idle cycle quantities and collision cycle quantities, so that the effective identification of antenna line devices is achieved, and the scanning time is reduced as well.
