[0002] As one of the important components of the servo turntable, the slip ring not only provides power for the pitch axis load of the servo turntable, but also is the key path for signal transmission between the load and the servo controller. It is mainly composed of two parts: the stator and the rotor. The brush and the conductive slide on the inner shaft realize the electrical rotation connection from the stator side to the rotor side through sliding contact.
[0003] However, in actual work:
[0004] There is inevitable mechanical wear between the key components of the slip ring, the ring and the brush. Since the wear process is usually gradual and irreversible, this wear is difficult to record and monitor by quantitative methods, making it impossible to accurately assess the working status of the slip ring and its remaining service life.

[0039] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose, the technical solutions in the embodiments of the present application are clearly described. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present application.
[0040] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.
[0041] The description of the method flow in the specification of the present application and the steps of the flowchart in the drawings of the present specification do not have to be strictly executed according to the step numbers, and the method steps can be executed in a different order. Moreover, some steps can be omitted, multiple steps can be combined into one step, and / or one step can be decomposed into multiple steps.
[0042] The following is a detailed description of the method, device and medium for periodically recording the number of revolutions of a slip ring provided in the embodiments of the present application in combination with the accompanying drawings and preferred embodiments.
[0043] See also Figure 1 , the embodiment of the present application provides a slip ring rotation number periodic recording device, such as Figure 1 As shown, the slip ring rotation number periodic recording device of the embodiment of the present application includes:
[0044] The servo turntable 1 can accurately control the rotation angle and speed; it includes an azimuth axis 2, on which a slip ring 3 is installed.
[0045] The slip ring 3 is used to maintain electrical connection while the servo turntable 1 rotates, allowing electrical signals or power to be transmitted through the rotating part to the fixed part.
[0046] The angle measuring element 4 is used to measure the angle value of the servo turntable 1 and transmit the measured angle data to the data processing board 5 .
[0047] The data processing board 5 is used to sample the angle data from the angle measuring element 4 and perform calculation processing to obtain the slip ring rotation data and store it in the memory 6 .
[0048] The memory 6 is configured as an EEPROM device for storing data even after power is turned off.
[0049] During the specific implementation process, the data processing board samples at a specific period (such as 1 millisecond), and records the current angle value each time it is sampled; compares the current angle value with the previous angle value; if the two are different, records the absolute difference between them; accumulates the absolute difference obtained previously in each cycle; when the accumulated value accumulates to 360°, it is considered that the slip ring has completed one rotation, at which time the accumulated value is cleared, and the number of revolutions of the slip ring is increased by 1 and recorded and stored.
[0050] Every set processing cycle (such as 1000 processing cycles, i.e. every second), the data processing board writes the current slip ring revolutions into the fixed address of the EEPROM to prevent data loss after power failure. When the power is turned on again, the data processing board reads the fixed address data of the EEPROM device and records it as the current slip ring revolutions.
[0051] See also Figure 2-3 , the embodiment of the present application provides a method for periodically recording the number of slip ring revolutions, such as Figure 2-3 As shown, the method for periodically recording the number of slip ring revolutions in the embodiment of the present application comprises the following steps:
[0052] Step S1, read the fixed address data of the EEPROM device to obtain the current slip ring rotation data;
[0053] Step S2, configure the sampling frequency to a set duration, obtain the servo turntable angle value multiple times according to the sampling frequency and record it;
[0054] Step S3, comparing the servo turntable angle value at time t with the servo turntable angle value at time t-1 to see if they are equal; if they are not equal, calculating the absolute value of the difference between the servo turntable angle values corresponding to time t and time t-1 and recording it;
[0055] Step S4, in each sampling period, the absolute value is accumulated and recorded as the accumulated value, and when the accumulated value reaches 360°, the accumulated value is cleared and the current slip ring rotation number is increased by 1.
[0056] Step S5, storing the updated slip ring revolution data into a fixed address of the EEPROM device every set value sampling period.
[0057] For example, in a specific implementation process:
[0058] The slip ring is installed on the azimuth axis of the servo turntable and moves with the servo turntable. At the same time, the angle measuring element transmits the motion state of the servo turntable to the data processing board. When the system is powered on, the data processing board starts working; the servo turntable moves under control, and the data processing board records the number of slip ring revolutions in real time; the data processing board stores the number of slip ring revolutions periodically; when the system is powered off, the recording work is completed. Figure 3 :
[0059] When powered on for the first time, the data processing board reads the fixed address data of the EEPROM device and records it as the current number of slip ring revolutions HH_count. The processing frequency of the data processing board is 1ms. The angle value of the servo turntable at the current moment is recorded as Ang[0], and the angle value of the servo turntable at the previous moment is recorded as Ang[1]. In each processing cycle, it is determined whether the angle value of the servo turntable at the current moment is equal to the angle value at the previous moment. If they are not equal, the absolute value of the difference is recorded in Ang_count[1]. In each processing cycle, the accumulation of Ang_count[1] is completed and recorded in the angle accumulation value Ang_count[0]. In each processing cycle, it is determined whether Ang_count[0] reaches 360°. When Ang_count[0] reaches 360°, it can be regarded as one rotation of the slip ring. At this time, Ang_count[0] is cleared and the number of slip ring revolutions HH_count is counted by one.
[0060] Every 1000 processing cycles (i.e. 1s), the slip ring revolution number HH_count data is recorded into a fixed address of the EEPROM device, thereby achieving the purpose of power-off storage.
[0061] Based on the above technical solution, the present application realizes effective monitoring of the working status of the slip ring by regularly recording the number of revolutions of the slip ring, which not only solves many problems faced in traditional slip ring maintenance, but also improves the overall performance of the slip ring and the servo turntable system in which it is located.
[0062] By regularly recording the number of revolutions of the slip ring, the wear of the core components of the slip ring (ring and brush) can be indirectly reflected, solving the problem of no quantitative record of wear. By using the regularly recorded data of the number of revolutions of the slip ring, the wear degree and remaining life of the slip ring can be more accurately predicted, so as to formulate a reasonable maintenance plan and reduce the risk of equipment failure caused by improper maintenance. By automatically recording the number of revolutions of the slip ring, the pressure of manual inspection is reduced, management efficiency is improved, and operating costs are reduced.
