Abstract

The invention discloses a machine running state online monitoring analysis system based on noise and vibration analysis. The system comprises a vibration measuring and collecting circuit, a noise measuring and collecting circuit, a DSP system, an ARM system, a network transmission system based on ZIGBEE and a computer server monitoring system. The vibration measuring and collecting circuit comprises a vibration measuring sensor, an amplifier circuit and an A / D converter circuit. The noise measuring and collecting circuit comprises a noise measuring sensor, an amplifier circuit and an A / D converter circuit. The DSP system comprises a DSP minimum system and a communication interface of a DSP and an ARM. The ARM system comprises an ARM minimum system and ZIGBEE transmission equipment controlled by the ARM for communication. The computer server monitoring system comprises network transmission equipment based on ZIGBEE and a center server computer. The machine running state online monitoring analysis system has the advantages that on the basis of integral running of the system, rapid recognition of the machine running state is well achieved, and great convenience is brought to rapid machine overhauling and large loss prevention.

Description

technical field [0001] The invention relates to an online monitoring and analysis system for machine running status, in particular to an online monitoring and analyzing system for machine running status based on noise and vibration analysis. Background technique [0002] There are many large-scale machinery and equipment controlled by motors in the large-scale factory workshop. They operate uninterruptedly for more than several hours a day, and even work continuously day and night. The reason is that the consequences of working for a long time may lead to a large number of defective products and even cause serious damage to large instruments and equipment, resulting in great economic losses. The equipment in the factory often judges whether the machine is running normally based on the experience of the workers and the production situation of the product. The machine may have been in an abnormal working state for a period of time. The result of such work will accelerate the d...
