And transmitting the motor rotation speed information to the information processing unit. The motor rotation speed information may be information indicating the rotation speed of the motor output shaft. The above information processing unit may be configured to perform the steps of:

in a first step, in response to determining that the type of motor included in the motor module 11 is a variable frequency motor, background decibel information corresponding to the motor module 11 is generated according to the received motor rotation speed information and the diameter of the inner ring of the bearing included in the motor module 11. In practice, first, the logarithm of the above motor rotation speed information with 10 as a base may be determined as the motor rotation speed logarithm. Next, a product of a preset first constant and a logarithm of the inner ring diameter based on 10 may be determined, wherein the preset first constant may be 0.6. Then, it can be determined that the logarithm of the second constant is preset with 10 as the base, resulting in the logarithm of the constant. Wherein, the preset second constant may be 2150. Then, the motor rotation speed logarithm, the sum of the product and the constant logarithm are determined.

In practice, the absolute value of the difference between the background db information and the received db information may be determined as standard db information corresponding to the motor module 11.

And thirdly, generating motor state information corresponding to the motor module 11 according to the standard decibel information. The motor state information may be information representing an operation state of the motor module 11. For example, the motor status information may be "motor, 0". In practice, in response to determining that the standard decibel information is less than or equal to a preset first decibel threshold, motor status information may be generated that characterizes that the motor module 11 is not malfunctioning. In response to determining that the standard decibel information is greater than the preset first decibel threshold and less than or equal to the preset second score Bei Yuzhi, motor status information may be generated that is indicative of a primary failure of the motor module 11. In response to determining that the standard decibel information is greater than the preset second fraction Bei Yuzhi and less than or equal to a preset third decibel threshold, motor status information may be generated that is indicative of a secondary failure of the motor module 11.

The first step-the fifth step are taken as an invention point of the embodiment of the disclosure, and the second technical problem mentioned in the background art is solved, when the motor of the motor module is a fixed frequency motor, the rotating speed is a constant value, the bearing state can be directly determined through the fixed rotating speed, but the motor of the motor module is a variable frequency motor, the rotating speed is influenced by the load of the machine set and changes in real time, the rotating speed cannot be directly determined, and thus the bearing state cannot be directly determined, and whether the motor module fails or not cannot be accurately determined, so that a worker is required to disassemble the motor module for detection, and the detection efficiency of the motor module is lower. The reason why the detection efficiency of the motor module is low is as follows: for the motor module in the granulator set, when the motor of the motor module is a constant frequency motor, the rotating speed is constant, the bearing state can be directly determined through the fixed rotating speed, but when the motor of the motor module is a variable frequency motor, the rotating speed is influenced by the load of the granulator set and is changed in real time, the rotating speed cannot be directly determined, so that the bearing state cannot be directly determined, and whether the motor module fails or not cannot be accurately determined, so that a worker is required to disassemble the motor module for detection. If the above factors are solved, the detection efficiency of the motor module can be improved. To achieve this effect, the granulator set detection apparatus of the present disclosure includes a rotation speed detection unit configured to perform rotation speed detection on the motor output shaft to obtain motor rotation speed information, and transmit the motor rotation speed information to the information processing unit. The above information processing unit is configured to execute the steps of: and generating background decibel information corresponding to the motor module according to the received motor rotating speed information and the diameter of the inner ring of the bearing included in the motor module in response to determining that the motor included in the motor module is a variable frequency motor. And generating standard decibel information corresponding to the motor module according to the background decibel information and the received motor decibel information. And generating motor state information corresponding to the motor module according to the standard decibel information.

And sending the motor fault early warning information to an associated terminal. From this, can carry out the rotational speed detection to above-mentioned motor output shaft through rotational speed detecting element, obtain motor rotational speed information to confirm real-time rotational speed, and then confirm the bearing state according to real-time rotational speed, need not the staff and unpack the motor module and detect. Thus, the detection efficiency of the motor module can be improved.

For example, the temperature sensor identification of the uppermost temperature sensor may be "01". The respective temperature sensor identifications of the respective temperature sensors below may be "02", "03", "04", and the like in order.

Optionally, each of the at least one level detection units may comprise a shielding device and a purging device. The shielding means may be means for shielding the temperature sensor.

the first step, responding to the received temperature information to include hopper temperature meeting the preset temperature threshold condition, and determining the temperature sensor identification corresponding to the temperature sensor below the temperature sensor corresponding to the temperature sensor identification included in the temperature information as the target temperature sensor identification. The preset temperature threshold condition may be that the hopper temperature is greater than or equal to a preset temperature threshold. The preset temperature threshold may be a temperature of the material. For example, in response to the temperature information including the temperature sensor flag being "01", the temperature sensor under the temperature sensor corresponding to the temperature information is flag being "02". The execution subject may determine "02" as the target temperature sensor identification.

And step two, determining each historical temperature information corresponding to the target temperature sensor identification. The respective historical temperature information may be a historical temperature detected by a temperature sensor corresponding to the target temperature sensor identifier.

And thirdly, determining the historical temperature information of which the hopper temperature meets the preset temperature threshold condition and included in each piece of historical temperature information as target historical temperature information, and obtaining a target historical temperature information set.

And step four, screening out the detection time closest to the current time from the detection times corresponding to the target historical temperature information set as the historical detection time.

And fifthly, determining a difference value between the historical detection time and the current time as a time interval.

And sixthly, determining the ratio of the preset temperature sensor interval size to the time interval as the material level increasing speed.

And seventh, generating hopper running state information according to the material level increasing speed in response to the material level increasing speed meeting a preset increasing speed condition. The preset increasing speed condition may be that the level increasing speed is greater than or equal to a preset level increasing speed threshold. The hopper operating status information may be information indicating whether the hopper operation has failed. For example, the above-described hopper operation status information may be "hopper operation is not malfunctioning". In practice, in response to the level increase rate being equal to or greater than a preset level increase rate threshold, a preset level increase rate range to which the level increase rate belongs may be determined. And then determining the preset hopper running state corresponding to the preset material level increasing speed range as hopper running state information.

Eighth, in response to determining that the hopper operating condition information characterizes a failure of the hopper module 14, hopper failure warning information is generated based on the hopper operating condition information. The hopper fault early warning information can be information for reminding workers of the hopper faults. For example, the hopper fault early warning information may be "the hopper is in a first-level fault and is required to be maintained in time".

The screw vibration detection unit may be configured to perform vibration detection on the screw cylinder to obtain cylinder vibration information. And transmitting the cylinder vibration information to the information processing unit.

Alternatively, the above information processing unit may be configured to perform the steps of:

And step two, generating double-screw track information corresponding to the double screws according to the double-screw displacement information sequence after the data preprocessing. In practice, first, the executing body may generate a polar coordinate set with the twin-screw horizontal displacement information included in the twin-screw displacement information as a polar axis and the twin-screw vertical displacement information included in the twin-screw displacement information as a polar diameter. Then, the executing body may perform curve fitting processing on the polar coordinate set to obtain twin-screw displacement curve information. The twin-screw displacement curve information may be information indicating a change in twin-screw displacement. The twin screw displacement curve information described above may be represented in the form of a curve.
