Description
Technical Field
The invention belongs to the technical field of hard disk storage, and is applied to a long-term storage maintenance process of a mechanical hard disk, in particular to a hard disk motor maintenance method and system based on wireless power-on.
Background
Currently, with respect to widely used personal computers and server devices, under the development of storage technology, both a mechanical hard disk (HARD DISK DRIVE, HDD) and a Solid-state storage disk (Solid STATE DISK, SSD) are configured. SSD hard disks have the advantage of high speed reading and writing, but if not powered on for long periods of time, the transistor gates within their Flash memory (Flash) can easily lose their original characteristics, resulting in failure of the stored data.
Therefore, for a scene requiring long-term data storage, an HDD hard disk is generally used, and there is also a scene need to pop up from the device for additional storage alone. According to the characteristics of the HDD hard disk, a main shaft in the HDD hard disk drives the magnetic disk to rotate, and a dynamic pressure bearing and a control motor are arranged on the main shaft; in the long-term non-energized storage process, the control motor cannot rotate, so that lubricating oil in the dynamic pressure bearing can be dried and solidified, the phenomenon of spindle adhesion is caused, a failure that the control motor cannot rotate occurs when energized operation needs to be recovered, and the HDD hard disk can be thoroughly damaged seriously.
In the prior art, aiming at a control motor in an idle HDD hard disk, under the condition of not accessing a computer and server equipment, a convenient technology for enabling the control motor to be self-started and maintained is not available; the prior technical proposal is mainly that an HDD hard disk is inserted into corresponding equipment, and is checked by using a hard disk self-checking management tool manufactured by a hard disk manufacturer after the power-on operation. The inspection mode mainly uses the automatic detection analysis of hard disk and report technology (Self-Monitoring ANALYSIS AND Report Technology, S.M.A.R.T.) to view the information of inspection report and hard disk bad track. For a control motor in an HDD hard disk, whether the motor is damaged or not is mainly judged according to factors such as whether the motor is started or not after power-on, whether abnormal sound is generated or not and the like. Under the detection and maintenance principle, the method for preventing the lubricating oil of the dynamic pressure bearing from solidifying is to connect the HDD hard disk into the equipment for read-write operation, so that the HDD hard disk normally works once to ensure the normal state of the control motor and the lubricating oil.
However, the above method of the prior art is extremely cumbersome and is especially disadvantageous for the normal operation of the server. If a batch of HDD hard disks are written with data, the HDD hard disks are stored in a warehouse for a long time, and the HDD hard disks in the server still work normally, when the HDD hard disks in the warehouse are required to be electrified, read-write and maintained regularly, the HDD hard disks of the server are required to be replaced, or the corresponding server is additionally purchased to read and write; the former delays the normal operation of the server and takes time to complete the maintenance of the old data, while the latter requires higher additional server cost due to the access technology of the existing HDD hard disk and the server, but the benefit is not high and is not necessary.

The system and its constituent elements will be described in detail and the maintenance principle will be described in this embodiment.
The realization principle of the whole hard disk motor maintenance system is as follows:
Under the support of self-contained management equipment such as RFID technology, the intelligent warehousing system can carry out HDD hard disk warehousing operation, and information data including hard disk batches, warehousing quantity, warehousing position and the starting time of the present warehousing are recorded during warehousing; the method is characterized in that the method comprises the steps of carrying out wireless power-on maintenance on hard disk storage, wherein the starting time of the storage is more important than the batch of hard disk, and when the starting time of the storage reaches three month time limits of the hard disk to be maintained, the hard disk of the batch is automatically taken out of the storage, and the wireless power-on maintenance process is carried out.
The intelligent warehousing system transmits the information to be maintained to the wireless power-on maintenance device, and an ESP32 chip microprocessor in the device is matched with a relay and other parts to realize the remote switch power-on function of the device.
When the wireless power-on maintenance device is started, the ESP32 chip microprocessor performs PWM pulse width modulation, converts direct current input by an external power supply into alternating current through a power full bridge, and generates a magnetic field in a transmitting coil. The magnetic field flows between the transmitting coil and the receiving coil, and alternating current is generated in the receiving coil again according to the electromagnetic induction principle; at this time, the alternating current is converted into direct current through a rectifier bridge additionally arranged in the HDD hard disk, and then the rotation of the hard disk motor is controlled through a three-phase inverter, so that the maintenance process of the hard disk motor of the HDD hard disk is completed. After maintenance is completed, the HDD hard disk of the batch may be warehoused again and awaited for the next maintenance.
The circuit principle of wireless power supply in this embodiment can refer to the schematic diagram of fig. 3, and the wireless power supply maintenance device uses the electromagnetic induction principle as a core and is based on the wireless connection structure of two induction coils, namely a transmitting coil and a receiving coil; on the transmitting coil side, an external power supply input, an SEP32 chip microprocessor, a power full bridge, a capacitor inductor and other devices form a wireless power-on maintenance device; on the receiving coil side, devices such as a rectifier bridge, a driving chip, a three-phase inverter, a capacitor inductor and the like form a wireless power-on assembly, and the wireless power-on assembly acts on a driving circuit of the hard disk motor.
In this embodiment, when the rectifier bridge inside the HDD hard disk converts the ac into dc, the dc can be directly input into the drive circuit of the hard disk motor, but since the hard disk motor is a three-phase brushless motor, the dc cannot directly supply power to the motor, and therefore, a three-phase inverter is added between the drive chip and the hard disk motor, so that the dc is converted into a three-phase current with constant voltage.
As shown in fig. 3, a driving circuit without a hall sensor is used here, and back electromotive force and lenz's law are also utilized, and when the hard disk motor rotates, electromotive force opposite to the motor coil group voltage is generated; the polarity of the counter electromotive force voltage is changed from positive to negative or from negative to positive, namely the counter electromotive force passes zero, and the driving chip recognizes the rotation speed position for reversing, so that the rotation of the hard disk motor is controlled.
