[0024] Referring to the accompanying drawings Figure 1 , the accompanying Figure 1 drawings show a schematic diagram of a real-time monitoring system for the operating state of a mine equipment. In the present embodiment, the mine equipment is a ball mill, and the ball mill has a motor 3, a bearing 2, a rotating body 1 (drum) and a motor speed regulating device, which is specifically a frequency converter.
[0025] In order to solve the problems in the background art, the monitoring system includes a temperature sensor, a current sensor, a rotating speed sensor, a sound sensor and a vibration sensor. Among them, the temperature sensor is installed on the outer ring of the bearing 2 for detecting the temperature of the bearing 2; the current sensor is used to detect the input current of the motor 3; the rotating speed sensor is a non-contact rotating speed sensor, which is installed on one side of the rotating body 1 for detecting the rotating speed of the rotating body 1; the sound sensor is also installed on one side of the rotating body 1 for detecting the noise of the rotating body 1; and the vibration sensor is installed on the outer ring of the bearing 2 for detecting the vibration of the bearing 2 and the rotating body 1.
[0026] The monitoring system further includes a data acquisition module and a data analysis and processing module, wherein the data acquisition module is used to acquire the output signals of the temperature sensor, the current sensor, the rotating speed sensor, the sound sensor and the vibration sensor. In the present embodiment, the data acquisition module is composed of a signal isolation circuit, a signal amplification circuit, a sample and hold circuit and an A / D converter.
[0027] In the embodiment, the data analysis processing module is a single-chip microcomputer, the input end of the data analysis processing module is connected with the data acquisition module, and the output end of the data analysis processing module is connected with the motor speed regulating device.
[0028] The working principle of the monitoring system is as follows:
[0029] During the operation of the equipment, if the bearing 2 and the rotating body 1 are abnormal, the bearing 2 will be heated, the motor 3 will be overloaded, the noise will be increased, the vibration will be enhanced, the transmission efficiency will be decreased (which is manifested as that the ratio of the rotating speed of the rotating body to the rotating speed of the motor is small, and the parts are slipping), and the like. At this time, the output signals of the temperature sensor, the current sensor, the sound sensor and the vibration sensor will exceed the normal value. After the data analysis processing module analyzes and processes the output signals of the temperature sensor, the current sensor, the sound sensor and the vibration sensor, the rotating speed of the motor 3 is appropriately reduced through the motor speed regulating device, the working conditions of the bearing 2 and the rotating body 1 are improved, and the equipment is prevented from being stopped due to the damage of the bearing 2 and the rotating body 1. It is known that the service life of the bearing 2 and the rotating body 1 depends on the rotating speed, the temperature and the lubrication and the like.
[0030] Further improved technical scheme, the monitoring system further comprises a database, the database is used for providing the data analysis processing module with the data of the past operation of the equipment, and the data analysis processing module is used for providing the data analysis processing module with the data of the past operation of the equipment.
[0031] Further improved technical scheme, the mine equipment further has a lubricating and cooling device, the lubricating and cooling device is connected with the output end of the data analysis processing module, and is used for lubricating and cooling the bearing 2. When the output signal of the temperature sensor exceeds the normal value, it indicates that the bearing 2 is seriously heated. At this time, the data analysis processing module sends an instruction, the lubricating and cooling device injects lubricating oil or cooling medium into the bearing 2, and the working conditions of the bearing 2 are improved.
[0032] Further improved technical scheme, the monitoring system further comprises a display and alarm device, the display and alarm device is connected with the output end of the data analysis processing module. The display and alarm device is used for alarming the working personnel through the display screen and the alarm lamp.
[0033] As known from the above, the monitoring system can monitor the working state of the bearing 2 and the rotating body 1 in the mine equipment in real time. When the monitoring system finds that the bearing 2 and the rotating body 1 are abnormal, the lubricating, cooling and reducing the rotating speed of the motor 3 are actively taken to improve the working conditions of the bearing 2 and the rotating body 1, and the mine equipment is prevented from being stopped due to the damage of the bearing 2 and the rotating body 1.
[0034] The part not described in detail is prior art. Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the protection scope of the utility model is defined by the appended claims and their equivalents.
