为了了解带式输送机的现场运行状况,使其发挥最高效率,通过大量理论研究与试验发现:带式输送机系统的许多故障信息是以调制的形式存在于所监测的电器信号与减速器振动信号中。通过监测用硬件解调电路及软件希尔伯特变换解调的信号可以达到对整个带式输送机系统运行状态的监测。
In order to understand the operation condition of the belt conveyor and make it play the highest efficiency, through a great deal of theoretical research and experiment, it is found that many failure information of the belt conveyor system exists in the form of modulation between the monitored electrical signal and the decelerator vibration Signal. The monitoring of the operating status of the entire belt conveyor system can be achieved by monitoring the signals demodulated with the Hilbert transform using hardware demodulation circuitry.
