Description

Technical Field

[0001] This utility model relates to the field of data storage security technology, specifically a new high-quality power supply device for improving data storage security. Background Technology

[0002] Storage capacity is one of the core infrastructures for the high-quality development of the digital economy. Its security directly affects the stability, credibility, and sustainable development capabilities of the digital economy. Storage capacity refers to the ability to store data, including storage capacity, efficiency, reliability, and security.

[0003] In terms of security, there are two aspects. One is the security of the stored data itself, such as end-to-end encryption to ensure the security of data both statically and dynamically. The other is the security of data during the storage process. This aspect is mainly reflected in storage failures caused by power supply problems, such as system crashes or data corruption that interrupt storage services. Or, the large amount of "instantaneous current," "surges," and "harmonics" generated by the frequent operation of electrical equipment and power supply networks, harmonic interference, overload, and aging of lines and equipment can cause current meandering and circling within the local power grid, making the power supply or data generated from the power source insecure. This poses a challenge to continuous and reliable data storage.

[0004] For the latter, the widespread adoption of 5G and IoT devices has brought about massive amounts of data. If the storage is unreliable or insecure, it will lead to service interruptions, affecting user experience and business decisions. At the same time, the introduction of new energy power sources such as wind power, photovoltaic power, and distributed grids will lead to defects such as instability, uncertainty, uncontrollability, and large fluctuations in the power supply network.

[0005] Chinese patent CN109196510A discloses a memory management method for a security module. Meanwhile, Chinese patent CN111737773A discloses an embedded security memory with an SE security module function. Both existing solutions protect the security of data itself in the data memory from the perspective of hardware or software. Moreover, most existing solutions improve the first aspect mentioned above without improving the power supply or power equipment itself. Utility Model Content

[0058] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0059] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0061] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0062] A novel high-quality power supply device for improving data storage security includes a device body, the input end of which is connected to the mains power supply network, and the output end of which is connected to a data storage device. The device body contains a generator, an automatic transfer switch, a power quality optimization mechanism, and a controller.

[0063] The controller can collect the current output from the device body to the data storage device. The controller is connected to the automatic transfer switch signal and controls the generator to start and stop.

[0064] The generator can supply power to the data storage via an automatic switching switch;

[0065] The mains power supply network can supply power to the data storage device via an automatic switching switch;

[0066] The power quality optimization mechanism can optimize the power quality for data storage devices.

[0067] The purpose of this design is to provide a power supply device that includes a generator, an automatic transfer switch, and a controller, along with a power quality optimization mechanism, which can optimize the power quality of the mains power supply network while providing safety protection for the use of data storage devices from a power supply perspective.

[0068] It should be noted that the controller can be equipped with a power management chip such as the TPS259XX series. The automatic transfer switch contains multiple relays, and a comparator and relays can also be used to achieve a similar effect. Taking the combination of comparator and relays as an example, when the mains power supply is working normally, the comparator built into the controller outputs a low level, and the relay controlling the automatic transfer switch does not operate. The entire data storage is powered by the mains power supply. However, the dual relay structure used in this embodiment prevents voltage fluctuations caused by the sudden restoration of the mains power supply when the generator is supplying power. Therefore, when the mains power supply is disconnected, it is actively disconnected. Subsequently, based on the restoration of the mains power supply, after eliminating the impact on the data storage, the relays are controlled to restore the mains power supply.

[0069] When the mains power supply network malfunctions, the comparator outputs a high level, the relay engages, and the generator supplies power to the data storage. The entire circuit connection can be simplified to have the controller and data storage connected in parallel, and the generator also connected in parallel with the data storage. Based on the above description, it can be understood that the automatic switching switch in this embodiment can switch between the generator and the mains power supply network based on the change of high and low levels in the circuit, without the need for software algorithms, and is implemented only through physical structure.

[0070] It should also be noted that in actual use, the controller can also connect to the monitoring terminal, such as remotely connecting to an energy-saving terminal, so as to adjust the temperature and humidity of the entire power supply device. Of course, this part is an extension of this embodiment, and those skilled in the art can choose appropriate existing technologies to implement it.

[0071] like Figure 1 As shown, in this embodiment, a data storage safety and energy-saving unit is installed inside the device body. The data storage safety and energy-saving unit is located between the automatic switching switch and the sampling point of the controller, and can optimize the power quality output to the data storage unit.

[0072] The purpose of this design is that the data storage security and energy-saving machine can provide safe use protection for power-consuming terminals such as data storage devices and other external devices based on its internal circuit structure, avoiding large fluctuations in power such as excessively high or low voltage.

[0073] In specific use cases, such as Figure 4 As shown, a specific structure of a data storage security and energy-saving machine is provided, wherein the data storage security and energy-saving machine includes a voltage sampling circuit, a PLC, a second AC contactor KM2, a third AC contactor KM3, and three output voltage control circuits.

[0074] The input terminals of the voltage sampling circuit are connected to the power supply line, and the output terminals of the voltage sampling circuit are connected to the analog input terminals of the PLC. The signal output terminals of the PLC are connected to one end of the coil of the second AC contactor KM2 and one end of the coil of the third AC contactor KM3. The other end of the coil of the second AC contactor KM2 is connected to one end of the normally closed contact of the third AC contactor KM3. The other end of the coil of the third AC contactor KM3 is connected to one end of the normally closed contact of the second AC contactor KM2. The other ends of the normally closed contacts of the third AC contactor KM3 and the second AC contactor KM2 are both connected to the neutral wire of the power supply line.

[0075] The first main inductors (L1-1, L1-2, L1-3) of the three output voltage control circuits are connected in series with the three normally open contacts of the second AC contactor KM2 on the three-phase output lines. The second main inductors (L2-1, L2-2, L2-3) of the three output voltage control circuits are connected in series with the three normally open contacts of the third AC contactor KM3 and then connected in parallel at both ends of the line formed by the series connection of the first main inductors (L1-1, L1-2, L1-3) and the normally open contacts of the second AC contactor KM2. The feedback inductors (L3-1, L3-2, L3-3) of the three output voltage control circuits are connected in series on the power supply line.

[0076] One end of the first main inductor coil, one end of the second main inductor coil, and one end of the feedback inductor coil of the output voltage control circuit are connected at the same point. The first main inductor coil and the feedback inductor coil are coils with the same name. When the second normally open contact of the second AC contactor KM2 is closed, the output voltage increases according to the principle of electromagnetic induction. The second main inductor coil and the feedback inductor coil are coils with different names. When the second normally open contact of the third AC contactor KM3 is closed, the output voltage decreases according to the principle of electromagnetic induction.

[0077] Furthermore, the data storage security and energy-saving structure of this embodiment also includes three soft-switch switches; the three soft-switch switches are respectively connected in parallel across the two ends of the circuit formed by the series connection of the first main inductor coil (L1-1, L1-2, L1-3) and the second normally open contact of the second AC contactor KM2. The soft-switch switches are used to prevent large fluctuations in the output voltage of the AC contactor during switching.

[0078] Furthermore, the data storage security and energy-saving machine structure in this embodiment also includes a first AC contactor; one end of the coil of the first AC contactor is connected to the signal output terminal of the PLC, and the other end of the first AC contactor is connected to the neutral wire of the power supply line; the three normally open contacts of the first AC contactor KM1 are connected in series with three soft switching switches and then connected in parallel to the two ends of the line after the normally open contacts of the first main inductor coil and the second AC contactor are connected in series.

[0079] The working principle of the data storage safety and energy-saving machine provided in this embodiment is as follows: the voltage sampling circuit collects the actual voltage value of the power supply line and transmits the collected actual voltage value to the PLC. The PLC compares the actual voltage value with the preset voltage value, and controls the opening and closing of the first AC contactor, the second AC contactor KM2, or the third AC contactor KM3 according to the comparison result. This, in turn, controls the switching of the first main inductor coil (L1-1, L1-2, L1-3) and the second main inductor coil (L2-1, L2-2, L2-3), thereby achieving the purpose of controlling the output voltage. The specific switching process is as follows:

[0080] When the actual voltage value is greater than the preset voltage value, firstly, the PLC controls the coil of the second AC contactor KM2 to de-energize, the normally open contact of the second AC contactor KM2 opens, the first main inductor coil (L1-1, L1-2, L1-3) and the feedback inductor coil (L3-1, L3-2, L3-3) no longer induct each other, and the normally closed contact of the second AC contactor KM2 closes.

[0081] Secondly, the PLC continues to control the coil of the first AC contactor to be energized, the normally open contact of the first AC contactor closes, and the input voltage is output to the voltage output terminal through a soft switching switch. The time interval of this switching process is less than 50ms. Then, the PLC controls the coil of the third AC contactor KM3 to be energized, the normally open contact of the third AC contactor KM3 closes, the second main inductor coil (L2-1, L2-2, L2-3) and the feedback inductor coil (L3-1, L3-2, L3-3) become mutually inducted, and the normally closed contact of the third AC contactor KM3 opens. At the same time, the PLC controls the coil of the first AC contactor to be de-energized, and the normally open contact of the first AC contactor opens. The switching time of this switching process is less than 50ms.

[0082] When the actual voltage value is less than the preset voltage value, firstly, the coil of the third AC contactor KM3 controlled by the PLC is de-energized, the normally open contact of the third AC contactor KM3 is opened, the second main inductor coil (L2-1, L2-2, L2-3) and the feedback inductor coil (L3-1, L3-2, L3-3) are no longer mutually inducted, and the normally closed contact of the third AC contactor KM3 is closed.

[0083] Secondly, the PLC continues to energize the coil of the first AC contactor, closing its normally open contact. The input voltage is output to the voltage output terminal through a soft switching switch, with a switching time of less than 50ms. Then, the PLC energizes the coil of the second AC contactor KM2, closing its normally open contact. The first main inductor coils (L1-1, L1-2, L1-3) and the feedback inductor coils (L3-1, L3-2, L3-3) become mutually inducted, and the normally closed contact of the second AC contactor KM2 opens. Simultaneously, the PLC de-energizes the coil of the first AC contactor, opening its normally open contact. The switching time of this process is less than 50ms.

[0084] This system collects the voltage of the main circuit through a voltage acquisition circuit. Based on the voltage changes, it controls the closing of the second AC contactor KM2 or the third AC contactor KM3, thereby regulating the output voltage. The automatic regulation is even more effective when multiple sets of positive and negative feedback coils are used. If the data storage safety and energy-saving machine suddenly experiences a short circuit, the current will suddenly increase. A reverse electromotive force (EMF) will be generated in the inductor coil, which opposes the change in magnetic flux. This reverse EMF will inevitably generate a reverse current, thus limiting the sudden increase in current and preventing the equipment from being impacted by large currents, thereby protecting the equipment.

[0101] One end of the second primary coil LB is connected to one end of the normally open contact of the eighth AC contactor KM8, and the other end of the second primary coil LB is connected to the other end of the first primary coil LA; the normally open contact of the ninth AC contactor KM9 is connected in parallel with the second primary coil LB; one end of the fourth secondary coil L4 is connected to one end of the normally open contact of the eighth AC contactor KM8, and the other end of the fourth secondary coil L4 is connected to the neutral wire through the normally closed contact of the tenth AC contactor KM10; one end of the normally open contact of the eleventh AC contactor KM11 is connected to one end of the fifth secondary coil L5, and the other end of the normally open contact of the eleventh AC contactor KM11 is connected to the other end of the fifth secondary coil L5.

[0103] Its specific working principle is as follows: the three sensors in the sampling circuit collect the voltage of each phase of the power supply line to obtain the corresponding first data, second data and third data. The sampling processor converts the first data, second data and third data to obtain the first analog data. The PLC compares the first analog data with the set value and controls the on and off of the second AC contactor KM2, the third AC contactor KM3, the fourth AC contactor KM4, the fifth AC contactor KM5, the sixth AC contactor KM6 and the seventh AC contactor KM7 according to the comparison result.

[0104] When the sampling circuit detects that the voltage data of one or more phases of the power supply is higher than the set value, the PLC controls the seventh AC contactor KM7 to turn on, and simultaneously controls any one of the third AC contactor KM3, the fourth AC contactor KM4, or the fifth AC contactor KM5 to close. At this time, the circuit state is a negative feedback step-down state. The simplified connection relationship is as follows: Figure 5 As shown, the winding direction of the secondary coil is the same as that of the first primary coil LA. At this time, according to Lenz's law, the voltage of the secondary coil increases, and the generated voltage affects the magnetic flux in the iron core, further affecting the first primary coil LA connected to it through the same iron core, and slowing down the rate of increase of the voltage and / or current of the first primary coil LA or reducing the voltage of the first primary coil LA.

[0105] When the sampling circuit detects that the voltage data of one or more phases of the power supply is lower than the set value, the PLC controls the second AC contactor KM2 to turn on, and simultaneously controls any one of the fourth AC contactor KM4, the fifth AC contactor KM5, or the sixth AC contactor KM6 to close. At this time, the circuit state is a positive feedback boost state. The simplified connection relationship is as follows: Figure 5 As shown, the winding direction of the secondary coil is opposite to that of the first primary coil LA. At this time, according to Lenz's law, the voltage of the secondary coil increases, and the generated voltage affects the magnetic flux in the iron core, further affecting the first primary coil LA connected to it through the same iron core, and increasing the voltage and / or current of the first primary coil LA.

[0109] The purpose of this design is that the dedicated data storage transformer, based on its internal circuit structure, can filter out and suppress electrical pollution caused by factors such as phase imbalance, insufficient power factor, frequent equipment operation, harmonic interference, and overload during use, which are the power input terminals of the mains power supply network. This improves power quality, increases energy saving rate, and ensures the safe use of the data storage device.

[0111] The secondary coil also includes a voltage regulating coil, which is connected in series with the reactance filter coil. The voltage regulating coil is connected between the output terminal of the transformer coil and the power supply line. The voltage regulating coil is not shown in the figure.

[0112] An adjustable contact K is provided between the output terminal of the transformer coil and the load. Through the adjustable contact K, the transformer coil is directly connected to the power supply line or indirectly connected to the power supply line through the reactance filter coil.

[0113] The secondary coil also includes a closed-loop control coil, one end of which is connected to the output terminal of the transformer coil, and the other end of which is connected to the transformer coil.

[0114] In this embodiment, the power supply line adopts three phases, and its source can be either the mains power supply network or a generator. The secondary coil also includes a current sharing coil / current sharing coil connected to the power supply line.

[0115] The current sharing coil is provided with optional contacts K1, K2 and K3 between itself and the load. The optional contacts K1, K2 and K3 are respectively connected to the three phase lines.

[0116] The reactance filter coil adopts a Z-type connection. The main coil and the reactance filter coil form three coil groups. Each coil group includes one main coil and at least one reactance filter coil. There are three magnetic cores, which are parallel to each other and arranged in a triangle. The main coil and the reactance filter coil of each coil group are wound on two adjacent magnetic cores respectively. Each magnetic core is fitted with one main coil and at least one reactance filter coil, and the main coil and the reactance filter coil do not come from the same coil group.

[0117] It should be noted that the structures of the data storage dedicated transformer and the data storage safety and energy saving machine are described separately in this embodiment. Due to the special nature of the circuit structure, different labels are inevitably used for the same component in the description. Since the structures of the data storage dedicated transformer and the two data storage safety and energy saving machines are independent of each other in the description, those skilled in the art can understand their circuit structures.
