Description

Technical Field

[0001] The invention belongs to the technical field of motor detection, and in particular relates to a large-scale generator and motor intelligent monitoring system. Background Art

[0002] In metallurgy, petrochemical, cement, and electric power and other enterprises and industries, the carbon brush and slip ring area and rotor and stator area of ​​large transmission motors are monitored by manual regular inspection (such as checking twice per shift, etc.), and the carbon brush and collector ring area of ​​large generators are monitored by manual regular inspection (such as checking twice per shift, etc.). The point inspection personnel judge the basic situation of the motor by means of touch, visual inspection, listening stick, meter reading, etc., and then conduct investigation based on experience after finding the problem. This method not only cannot achieve real-time monitoring, but also has low accuracy. In addition, there are certain safety hazards when the inspection personnel approach the motor equipment at close range. At the same time, due to the rotation characteristics of the motor stator and slip ring and other equipment, it is impossible to measure the temperature by direct contact methods such as thermocouples. Therefore, the temperature monitoring of such equipment cannot be accurately measured, and the internal operation and various hidden dangers of large generators and motors cannot be monitored in real time and comprehensively. The hidden dangers and hazards are as follows;

[0003] 1. When the rotor and stator of a large transmission motor overheat or spark, the hidden dangers will expand rapidly, which may cause the stator and rotor to burn out, resulting in the burning of the motor;

[0004] 2. When the carbon brushes and slip rings of large transmission motors are overheated, they may burn out, and even cause fire and burn out the motor;

[0005] 3. When the carbon brushes and collector rings of large generators over-temperature, it may cause sparks and ring fires, burn the carbon brushes and collector rings, and even cause fires and burn the motors.

[0006] There are no visual and intelligent program recognition and monitoring methods for faults such as overheating and sparking in important single equipment inside these large generators and motors, and real-time monitoring has not been achieved. Small faults quickly lead to major accidents, resulting in shutdown of the entire line or production reduction. Summary of the invention

[0007] In view of the above problems, the present invention is proposed to provide a large-scale generator and motor intelligent monitoring system that overcomes the above problems or at least partially solves the above problems.

[0016] The thermal imaging monitoring data acquisition unit is used to collect the temperature field graphic information of the rotor, stator, carbon brush and slip ring of large motors in real time, and the temperature field graphic information of the carbon brush and collector ring area of ​​large generators in real time.

[0017] Optionally, the machine-side data processing module performs intelligent recognition on the collected video data through a neural network program, identifies spark information, maximum temperature, minimum temperature and average temperature, and transmits the video data and recognition operation information to the server module.

[0018] Optionally, the secondary processing includes storage, drawing a time curve graph, over-limit alarm, storing data into a database and alarm video playback.

[0019] Optionally, the intelligently identified information includes the number of sparks and the spark area, as well as the maximum temperature of the monitoring area, the minimum temperature of the monitoring area and the average temperature of the monitoring area.

[0020] Optionally, the display module will alarm and push alarm information when abnormal information occurs in large generators and motors.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0022] 1. The present invention introduces monitoring equipment such as industrial cameras and infrared thermal imagers for monitoring, and uses neural networks to identify faults such as sparks in the equipment during operation, and can promptly alarm when such faults occur.

The present invention uses an infrared thermal imager to monitor the temperature of large generators and internal moving equipment of motors, and can obtain the maximum, minimum and average temperatures in the temperature field in real time. When the set temperature value is exceeded, an alarm is issued in time.

[0024] 3. The present invention can comprehensively judge the operating status of large generators and motor equipment. When ignition or over-temperature operation failures occur, the intelligent monitoring system will issue an alarm, and engineers will deal with it in time to avoid the expansion of the accident and reduce downtime and losses.
