[0020] Example 1:

[0021] like Figures 1-4 As shown, a monitoring system for a cable production traction device is provided. The traction device includes multiple synchronous pulleys and a synchronous toothed belt 2 connected to the synchronous pulleys. At least one of the multiple synchronous pulleys is a drive wheel 1. A traction wheel wear monitoring sensor 3 is provided on one side of the drive wheel 1. The traction wheel wear monitoring sensor 3 is used to monitor the wear condition of the drive wheel 1.

[0022] The aforementioned traction wheel wear monitoring sensor 3 uses a laser rangefinder or an ultrasonic sensor.

[0023] Non-contact distance monitoring using laser rangefinders or ultrasonic sensors enables non-contact monitoring of drive wheel wear. The distance between the sensor and the drive wheel is calculated using the emission and return times of the laser or sound waves. If the detected distance exceeds the set value, the drive wheel wear is out of tolerance, and the system issues a wear tolerance warning after calculation.

[0024] The detection direction axis of the aforementioned traction wheel wear monitoring sensor 3 is perpendicular to the rotation axis of the drive wheel 1.

[0025] The detection direction of the aforementioned traction wheel wear monitoring sensor 3 is directly opposite to the tooth direction of the toothed wheel body 102 of the drive wheel 1.

[0026] The aforementioned traction wheel wear monitoring sensor 3 is electrically connected to the wear data processing device 4.

[0027] The wear data processing device 4 is a transmitter and data processing circuit that is matched with the sensor. Since the toothed wheel body 102 is uneven, the distance data detected by the wear data processing device 4 will change with the rotation size. The minimum value is the distance from the tooth tip to the sensor. By filtering the distance data of the tooth tip through the data processing circuit, the distance information of each tooth tip can be obtained, thereby judging its wear condition.

[0028] In the preferred embodiment, the wear data processing device 4 is connected to the traction controller 7, the drive wheel 1 is driven to rotate by the drive motor 5, the drive motor 5 is electrically connected to the motor driver 6, and the motor driver 6 is connected to the traction controller 7.

[0029] The traction controller 7 controls the motor driver 6 according to the set data, causing the drive motor 5 to rotate. The feedback information of the drive motor 5 is obtained by the motor driver 6 and transmitted to the traction controller 7. The traction controller 7 can obtain the current speed of the drive wheel 1, and then obtain the signal frequency of the tooth tip from the index of the wheel body. The traction controller 7 compares the calculated frequency with the time-stamped distance information received from the wear data processing device 4, and can then separate the corresponding tooth tip distance data. The tooth tip data is processed to obtain its dispersion rate information. Since the wear of the wheel body is not uniform, the magnitude of this dispersion rate information represents the degree of wear.

[0030] In a preferred embodiment, the wear data processing device 4 is connected to the traction controller 7, the shaft of the drive wheel 1 drives the drive wheel encoder 8 to rotate, and the drive wheel encoder 8 is connected to the traction controller 7.

[0031] The drive wheel encoder 8 mentioned above is an absolute encoder.

[0032] By monitoring the rotational angular velocity of the current drive wheel using an encoder, and obtaining the signal frequency of the tooth tip from the number of teeth on the drive wheel, the distance information of the tooth tip can be separated from the time-continuous distance information. From the distance information of the tooth tip, the wear degree of the wheel body can be determined. Furthermore, since the encoder is an absolute encoder, the position of the encoder and the position of the drive wheel teeth are fixed, and the specific tooth or teeth that are worn out can also be determined from the tooth tip distance information.
