监测软件是机械状态监测系统的重要组成部分，提高软件的分析精度十分必要。推导出由于多通道信号循环采集而产生的相位误差的补偿方法；对于因条件的限制无法获取整周期触发信号的情况，提出了非整周期轴心轨迹圆整的概念。监测过程中有时需要将速度或加速度传感器的信号转换成位移或速度信号，为了降低监测系统的成本提出用软件积分代替硬件积分的方法。以上措施在ＴＤ８００旋转机械状态监测系统中获得了较好的应用，对于提高软件分析精度具有一定的实际意义。
Monitoring software is an important part of the mechanical condition monitoring system. It is necessary to improve the analysis accuracy of the software. The compensation method of phase error caused by multi-channel signal acquisition is deduced. For the condition that the full-cycle trigger signal can not be obtained due to the restriction of the condition, the concept of rounding of non-full-cycle axis trajectory is proposed. During the monitoring process, it is sometimes necessary to convert the signal of the speed or acceleration sensor into a displacement or speed signal. In order to reduce the cost of the monitoring system, a software integral instead of a hardware integral is proposed. The above measures have been applied well in TD800 rotating machinery condition monitoring system, which has certain practical significance for improving software analysis precision.
