本文提出一种基于“例外报告”的振动数据采集方案 ,并给出常规信号与振动信号“例外报告”的含义。由此构成的下位机数据采集系统 ,只有当采集信号有明显变化时 ,才将相关数据向上位机传送。该方案可保证在不丢失有用信息的情况下 ,大大减少数据传输量。 This paper presents a vibration data acquisition scheme based on “Exception Report” and gives the meaning of “exceptional report” of conventional signals and vibration signals. The resulting lower computer data acquisition system, only when there is a significant change in the acquisition signal, the relevant data to the host computer to send. This scheme can guarantee to reduce the data transmission amount greatly without losing useful information.
