Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0018] Based on relevant technologies, mainstream main controller manufacturers set the temperature specification of mechanical hard disks at 50°C, which is the lowest temperature specification in the entire machine. During the operation of the main controller, the mechanical hard disk is prone to overheating.
[0019] Currently, in order to prevent mechanical hard drives from overheating, manufacturers will adjust the fan to a fixed, high-speed operating state.
[0020] However, when the temperature of the mechanical hard disk is low, the fan still runs at a high speed, which consumes a lot of energy. Moreover, when the fan keeps running at a high speed, it will cause a lot of noise, affecting the customer experience.
[0021] Based on this, this embodiment provides a control system based on a mechanical hard disk, which obtains the load of the mechanical hard disk during operation through the main controller, and then sends current to the power supply line through the load. The resistor determines its corresponding voltage through the input current, and the control component adjusts the controlled component through the voltage corresponding to the resistor, so that the controlled component can be dynamically adjusted according to the temperature of the mechanical hard disk, thereby reducing energy consumption, reducing noise, and improving user experience.
[0022] In this embodiment, a control system based on a mechanical hard disk is provided. Figure 1 As shown, the control system includes: a main controller 102, a power connection component 101, a resistor 103, a controlled component 106 and a control component 105; the power connection component 101 is connected to the mechanical hard disk and is used to input power to the mechanical hard disk; the main controller 102 is connected to the mechanical hard disk through a power supply line 107, and is used to receive the resistance value of the power supply line 107, and input current to the power supply line 107 based on the resistance value of the power supply line 107; the resistor 103 is connected to the power connection component 101 at one end and to the control component 105 at the other end, and is used to receive the input current and determine the voltage corresponding to the resistor 103 based on the input current; the control component 105 is connected to the controlled component 106, and is used to adjust the controlled component 106 based on the voltage corresponding to the resistor 103; wherein the controlled component 106 is used to adjust the temperature of the mechanical hard disk.
[0023] The main controller 102 is an important part of the computer hardware system, which can be configured in the host computer. The main controller 102 can be a central processing unit (CPU), etc., which is not specifically limited here.
[0024] The power connection component 101 may be used to represent a component that transmits power to a mechanical hard disk. The power connection component 101 may be a mechanical hard disk power connector. The power connector of a mechanical hard disk is generally an interface for connecting the hard disk to a power source to provide power supply. For most mechanical hard disks, the power connector may be a standard power interface with specific pin definitions and voltage requirements.
[0025] Optionally, the power interface of the hard disk includes positive and negative power pins for receiving the DC power supply of the power supply. The specific interface form and pin definition may vary depending on the model and specifications of the hard disk. Therefore, when connecting the hard disk power supply, you should ensure that it is correctly connected according to the interface definition of the hard disk to avoid damaging the hard disk or the power supply.
[0026] In addition, stability is also very important for the power supply of mechanical hard disks. If the power supply is unstable or has ripples, it may have an adverse effect on the service life and performance of the hard disk. Therefore, when choosing a power supply product, you need to pay attention to parameters such as ripple performance to ensure the stable operation of the hard disk.
[0027] A mechanical hard disk drive (HDD) is mainly composed of a disk, a magnetic head, a disk shaft, a control motor, a magnetic head controller, a data converter, an interface, a cache, and other parts. When working, the magnetic head can move along the radius of the disk. With the high-speed rotation of the disk at several thousand revolutions per minute, the magnetic head can be positioned at a specified position on the disk to read and write data. Information is written to the disk by the electromagnetic flow through the magnetic head, which is very close to the magnetic surface, by changing the polarity of the electromagnetic flow. The information can be read in the opposite way. As a precision device, dust is its biggest enemy, so the air entering the hard disk must be filtered.
[0028] Specifically, a resistor 103 is added to the power supply circuit 107 of the mechanical hard disk of the mainboard, and the voltage across the resistor 103 is connected to the port of the control component 105. The control component 105 converts the voltage into temperature, thereby adjusting the controlled component 106 to adjust the temperature of the mechanical hard disk.
[0029] This embodiment provides a control system based on a mechanical hard disk, which obtains the load of the mechanical hard disk during operation through a main controller, and then sends current to the power supply line through the load. The resistor determines its corresponding voltage through the input current, and the control component adjusts the controlled component through the voltage corresponding to the resistor, so that the controlled component can be dynamically adjusted according to the temperature of the mechanical hard disk, thereby reducing energy consumption, reducing noise, and improving user experience.
[0030] In an optional implementation, the component under test may be a fan.
[0031] Specifically, a resistor 103 is added to the power supply circuit 107 of the mechanical hard disk of the mainboard, and the voltage across the resistor 103 is connected to the port of the control component 105. The control component 105 converts the voltage into temperature, thereby adjusting the wind speed of the fan to regulate the temperature of the mechanical hard disk.
[0032] This embodiment provides a control system based on a mechanical hard disk. By converting a voltage signal into temperature information, the control component can intelligently sense the operating temperature of the mechanical hard disk and adjust the fan speed in real time according to the temperature. This intelligent temperature control mechanism can effectively avoid the performance degradation and damage of the hard disk caused by overheating, and improve the reliability and stability of the hard disk. Due to the precise measurement and conversion of the resistor and the control component, the system can accurately obtain the real-time temperature of the mechanical hard disk and accurately adjust the fan speed as needed. This precise control helps to keep the hard disk working within the optimal temperature range, thereby improving its working efficiency and life.
[0033] In an optional embodiment, the control system further includes: a voltage amplifier circuit 104 ; the voltage amplifier circuit 104 is disposed between the resistor 103 and the control component 105 , and one end of the voltage amplifier circuit 104 is connected to the resistor 103 , and the other end of the voltage amplifier circuit 104 is connected to the control component 105 .
[0034] The voltage amplifier circuit 104 is a circuit for amplifying a voltage signal. It can increase the amplitude of the input signal to a desired level so that it can be processed or drive other circuits in subsequent electronic devices. This circuit is usually composed of an amplifier and a series of auxiliary devices, such as capacitors, inductors, resistors 103, etc. The voltage amplifier circuit 104 has a common-emitter amplifier, a common-collector amplifier, a common-base amplifier, etc. Specifically, the working principle of the voltage amplifier circuit 104 is based on the internal circuit of the amplifier. When the input signal passes through the amplifier circuit inside the amplifier, the voltage value of the output signal is increased by increasing the amplitude of the voltage. This process is completed by the amplification elements (such as transistors, electron tubes, etc.) inside the amplifier.
[0035] In the control system based on the mechanical hard disk provided in this embodiment, the voltage signal at both ends of the resistor will have its amplitude significantly increased after passing through the voltage amplification circuit, thereby improving the strength of the signal. This can not only ensure that the control component can receive a signal of sufficient strength, but also reduce the attenuation and distortion of the signal during transmission, thereby improving the accuracy and reliability of the entire control system.
[0036] In an optional implementation, the resistor 103 may be a precision resistor.
[0037] Precision resistors are electronic components that provide high-precision resistance values and have the characteristics of high accuracy, high stability and low-temperature drift rate.
[0038] The mechanical hard disk-based control system provided in this embodiment has a very high resistance value accuracy of precision resistors, which can usually reach an accuracy level of ±0.01% or even higher. In the circuit, the precision resistors can more accurately control the current and voltage, thereby improving the performance and stability of the entire circuit.
[0039] In addition, the temperature coefficient (TCR) value of precision resistors is low, and their resistance value changes less with temperature. Therefore, in high or low temperature environments, precision resistors can maintain a relatively stable resistance value and avoid circuit performance fluctuations caused by temperature changes.
[0040] In addition, the temperature drift characteristics (the degree to which the resistance value changes with temperature) of precision resistors are very good, and can achieve very low temperature drift values, such as ±1ppm / ℃ or even lower. This makes precision resistors perform well in applications that require high precision and stability. The noise index of precision resistors is usually low, which means that in the circuit, the noise interference generated by precision resistors is small, which is conducive to improving the signal-to-noise ratio and the performance of the overall circuit.
[0041] In an optional implementation, the control component 105 is a fan speed control chip or an embedded controller.
[0042] The fan speed control chip is the core component of the fan speed controller, which is responsible for adjusting the fan speed according to the environmental parameter signal detected by the sensor. Specifically, the fan speed control chip reads the temperature sensor data on the motherboard or device, and intelligently adjusts the fan speed according to these data to adapt to different heat dissipation requirements. Specifically, the fan speed control chip usually integrates the drive circuit and the microcontroller. This highly integrated design simplifies the circuit design, reduces power consumption, and ensures performance. In addition, it also has the characteristics of intelligent control, which can automatically adjust the fan speed according to temperature changes to achieve intelligent management of the fan.
[0043] An embedded controller is a control system capable of processing data in a complex manner, and is mainly controlled by an embedded microelectronics chip (including a series of microelectronic devices such as a microprocessor chip, a timer, a sequencer or a controller). It can perform specified independent control functions and complete various automated processing tasks such as monitoring and control. Specifically, the embedded controller controls the speed of the fan by converting temperature.
[0044] In the mechanical hard disk-based control system provided in this embodiment, both the fan speed control chip and the embedded controller have the ability of precise control. The fan speed control chip can adjust the fan speed in real time according to the temperature signal, while the embedded controller can accurately control and adjust the fan speed through its high-performance processor and real-time operating system. This precise control helps to keep the fan in the best working state, improve the heat dissipation efficiency, and reduce energy consumption and noise.
[0045] In an optional implementation, the control component 105 is used to increase the temperature corresponding to the control component 105 when the voltage of the resistor 103 increases, so as to increase the rotation speed of the fan.
[0046] The control component 105 is used to reduce the temperature corresponding to the control component 105 when the voltage of the resistor 103 decreases, so as to reduce the rotation speed of the fan.
[0047] Specifically, when the load of the mechanical hard disk increases, the current of the mechanical hard disk power supply circuit 107 on the mainboard increases, the voltage across the resistor 103 increases, and the temperature after conversion of the control component 105 increases, thereby increasing the speed of the controlled component 106 (such as a fan); conversely, the current of the mechanical hard disk power supply circuit 107 on the mainboard decreases, the voltage across the resistor 103 decreases, and the temperature after conversion of the control component 105 decreases, thereby decreasing the speed of the fan, thereby realizing intelligent control of the speed of the controlled component 106 (such as a fan) according to the load of the mechanical hard disk.
[0048] The control system based on the mechanical hard disk provided in this embodiment can accurately sense the temperature change of the system or hard disk by monitoring the voltage change of the precision resistor. When the voltage increases, the temperature corresponding to the control component will also rise, thereby triggering the increase of the fan speed; on the contrary, when the voltage decreases, the temperature corresponding to the control component 105 decreases, and the fan speed will also decrease accordingly, thereby ensuring the real-time matching of the fan speed and the temperature requirement, and improving the heat dissipation efficiency.
[0049] In addition, because the control component can dynamically adjust the fan speed according to actual needs, unnecessary energy consumption is avoided. When the temperature is low, the fan speed is reduced to reduce power consumption; when the temperature is high, the fan speed is increased to ensure the heat dissipation effect, while also avoiding energy waste caused by overheating. This intelligent speed regulation mechanism helps to achieve energy conservation and emission reduction, in line with the concept of green environmental protection.
