Method and system for monitoring self-control energy-saving motor

Abstract

The invention relates to a method and a system for monitoring a self-control energy-saving motor. The system comprises at least one self-control energy-saving motor, a monitoring center, and a data communication network connected with the self-control energy-saving motor and the monitoring center, wherein the self-control energy-saving motor is fixedly provided with a parameter measuring device, a signal transmission circuit, a power supply circuit, a communication interface and a first controller, and can acquire and measure parameters of a rotating shaft of the self-control energy-saving motor, convert the parameters into digital signals for output, receive control data sent by the monitoring center, convert the control data into corresponding control instructions and execute the instructions. The method and the system realize acquisition of working states of the parameters of the rotating shaft of the motor through introducing the novel self-control energy-saving motor, realize local or remote monitoring for the self-control energy-saving motor according to the acquired parameter signals, ensure the timeliness and effectiveness of motor fault detection and reduce the probability of fault occurrence.

Description

Technical field [0001] The invention relates to a motor monitoring method and system, in particular to a self-control energy-saving motor monitoring method and system. Background technique [0002] The motor is the backbone of the industry. At present, many industrial departments and manufacturing companies use a large number of motors. However, due to the service life of the motor or other reasons in the motor work, the motor will inevitably fail. These failures may cause production to stop. Leading to costly shutdowns and maintenance losses, and because of the large number of motor parts, there are also more parts and reasons for motor failures. Also, due to the large number of motors and scattered distribution, the motor and its The detection of the cause of the fault is usually very difficult, and this difficulty is exacerbated by the usually harsh working environment of the motor. [0003] At present, in most domestic motor manufacturers, the detection of motors usually adop...

Problems solved by technology

One of the existing technologies is a patent with a patent publication number of 1611955, which discloses a distributed motor monitoring system. Its significant disadvantage is that it can only monitor the motor, but cannot control the motor, so it cannot achieve effective monitoring. To prevent the failure of the motor and ensure the real-time control of the motor

The second prior art is the patent with the patent publication number of 101158865, which discloses a generator monitoring system device. Its significant disadvantage is that the motor monitoring system device described in this patent can only monitor the general operating status of ordinary motors. Simple monitoring does not involve the monitoring of specific performance parameters of the motor shaft, so it cannot effectively monitor other complex faults of the motor, and its monitoring method is limited to remote monitoring
