Description
Technical Field
The invention relates to the technical field of heat dissipation equipment, in particular to a hot start method and a hot start device for a fan.
Background
JBOD (Just a Bunch Of Disks) is a storage device with a plurality Of disk drives mounted on a frame. The disk drive can be inserted into the frame from the front side of the frame, and in order to realize good heat dissipation of the disk drives, the back side of the frame is generally provided with a plurality of single fans, so that the single fans are independent from each other for maintenance convenience and can be assembled and disassembled in a plug-in mode from the back side of the frame.
A plurality of monomer fans constitute fan module, and fan module during operation can outwards discharge the inside heat of frame fast. If one single fan is broken, in order to ensure the heat dissipation performance, only the single fan to be overhauled needs to be shut down and disassembled, and other single fans cannot be shut down and disassembled.
After the single fan to be overhauled is detached, the original mounting hole is reserved, and since other single fans do not stop working, outside air can enter the frame through the mounting hole under the driving action of other single fans, namely, the mounting hole can generate a first air flow flowing from outside to inside.
When the detached single fan is repaired, the detached single fan needs to be installed at the installation hole again, and then the installed single fan is restarted, wherein the installed single fan is used for driving the air inside the frame to flow outwards, namely, the installed single fan is used for generating a second air flow from inside to outside at the installation hole.
Obviously, the first air flow will act as a counter flow to the second air flow, preventing proper start-up of the reinstalled single fan. In practical work, the single fans arranged on the frame are large in number, the strength of the first air flow is high, and the single fans which are installed again are difficult to start normally against the strong reverse flow effect. As a result, the reinstalled single fan often fails to start properly.
At this time, if all the single fans are directly and uniformly shut down, the reverse flow can be eliminated, then all the single fans are uniformly turned on, and the single fans which are installed again can be restarted, but the shut-down of all the single fans has a certain downtime risk, and even the whole information transmission system is rushed, so the operation is not preferable.
Therefore, there is a need for a method for hot starting a fan, which is used to solve the problem that the fan to be started cannot be hot started in the fan module.
The above information disclosed in this background section is only included to enhance understanding of the background of the disclosure and therefore may contain information that does not form the prior art that is currently known to one of ordinary skill in the art.

Example 1
The embodiment provides a hot start method of a fan, which is suitable for reconnecting and starting an application scene of the fan to be started under the condition that other single fans are not turned off after any fan to be started in a fan module is detached and overhauled, so that the hot start of the fan to be started in the fan module can be effectively realized under the condition that the downtime risk is reduced as much as possible, and the overhauling efficiency and convenience are improved.
Referring to fig. 1, the fan warm start method includes:
s11: and judging whether the single fan exists in the fan module or not to be electrically disconnected. And if so, marking the single fan corresponding to the disconnected mounting hole as a fan to be started.
Generally, the fan module includes a plurality of single fans, and each single fan is arranged in a matrix, such as a nine-grid arrangement of 3 × 3 or a twenty-four-grid arrangement of 4 × 6. The quick connector is correspondingly arranged at the mounting hole of each single fan, so that the single fans are electrically connected with the quick connector, and then the single fans can be controlled independently or in a centralized manner.
Under the normal condition, all the single fans in the fan module run at the same rated rotating speed, if a certain single fan is disconnected from the electric connection in the working process of the fan module, it can be determined that the single fan corresponding to the mounting hole needs to be overhauled or replaced, no matter the single fan is overhauled and then reconnected to be started, or a new single fan is taken to be connected to be restarted, the single fans subsequently installed in the mounting hole are marked as fans to be started, that is, as long as the quick connector at the mounting hole is disconnected from the electric connection, the single fan subsequently reconnected to the quick connector is the fan to be started.
S12: judging whether the fan to be started is reconnected; if so, sending an instruction for starting the fan to be started; if not, continuously monitoring the reconnection state;
s13: judging whether the fan to be started is started successfully or not; if yes, go directly to step S15; if not, performing speed reduction treatment on at least one adjacent fan around the fan to be started; and maintaining the rotational speed of the peripheral fan other than the fan to be started and the at least one adjacent fan constant.
It should be noted that, because the individual fans are arranged in a matrix, the individual fans may be arranged in eight directions, such as above, below, left side, right side, above left side, above right side, below left side, and below right side, of the fan to be started.
If the fan to be started is located at the left edge position, only six directions, namely upper direction, lower direction, right direction, upper right direction, lower right direction and the like, exist in the adjacent fan. If the fan to be started is located at the upper edge position, only six directions, namely, the left direction, the lower direction, the right direction, the left lower direction and the right lower direction, exist in the adjacent fan. By analogy, the specific position of the adjacent fan is not described in this embodiment.
In this embodiment, there is only one layer of adjacent fans, that is, in a 3 × 3 squared figure with the fan to be started as the center, the eight individual fans around the center are all adjacent fans. In some other embodiments, the adjacent fans may be two layers, that is, in a 5 × 5 squared grid with the fan to be started as the center, all of the 24 individual fans outside the center are adjacent fans; or, the adjacent fans can be three layers, namely, in a 7 × 7 squared case with the fan to be started as the center, the 48 single fans outside the center are all adjacent fans. Certainly, the adjacent fans can also be four layers, five layers or more, and the specific number of the adjacent fans is not described in detail in this embodiment; generally, the number of adjacent fans is less than the total number of individual fans included in the fan module.
In this embodiment, after detecting that the fan to be started fails to start, the system determines that the reverse flow effect is strong, resulting in the locked-rotor of the fan to be started. Generally, the reverse flow effect of the adjacent fan around the fan to be started is the strongest, so that firstly, considering to reduce the rotating speed of the adjacent fan and even turn off the adjacent fan, a larger reverse flow strength reduction value can be obtained at the expense of smaller heat dissipation speed loss, namely, the influence on the heat dissipation effect of the fan module is not large, but the reverse flow effect can be greatly reduced, so as to be beneficial to the normal starting of the fan to be started.
Of course, in some other embodiments, if the fan to be started fails to start, the number of adjacent fans may be increased, that is, only the first layer (eight) of adjacent fans around the fan to be started is rotated at the beginning; if the starting fails, reducing the rotating speed of the second layer (twenty-four) of adjacent fans at the periphery of the fan to be started; if the start fails, the rotation speed … of the adjacent fan at the third layer (forty-eight) around the fan to be started is reduced, and so on, which is not described in detail in this embodiment.
S14: judging whether the fan to be started is started successfully or not; if yes, go directly to step S15; if not, all the single fans except the fan to be started are subjected to graded speed reduction processing until the fan to be started is started successfully.
If the adjacent fan cannot be started normally after the rotating speed of the adjacent fan is reduced, the current reverse flow effect is still strong, and the reverse flow effect needs to be further reduced. In this embodiment, in order to further reduce the reverse flow effect without completely losing the heat dissipation effect, only the graded speed reduction processing is performed on all the remaining single fans except the fan to be started, and a measure of directly shutting down all the remaining single fans is not taken.
Further, the S14 includes:
s141: judging whether the fan to be started is started successfully or not; if yes, go directly to step S15;
s142: if not, repeatedly executing S1421 and S1422 until the fan to be started is successfully started;
s1421: reducing the rotating speed of all the single fans except the fan to be started by one grade; wherein the rotating speed of the next grade is less than the rotating speed of the previous grade;
s1422: and judging whether the fan to be started is started successfully or not.
In this embodiment, the rotation speed between the next level and the previous level is in a functional relationship, for example, the rotation speed of the next level is 70% or 60% of the previous level, and the like, that is, the rotation speed of all the single fans is reduced by 30% or 40% each time; alternatively, the next level of rotation speed is 200 revolutions/min less than the previous level of rotation speed, i.e. every time the rotation speed of all the individual fans is reduced by 200 revolutions/min.
Alternatively, the rotation speed of each level is specified by the database, for example, the rotation speed corresponding to each level is directly specified in the database, for example, the first-level rotation speed is specified as the rated rotation speed, the second-level rotation speed is 5000 rpm, and the third-level rotation speed is 4000 rpm.
In this embodiment, before step S14 is taken, there are two rotation speeds for each single fan in the fan module, namely, the adjacent fans are fewer single fans, and the single fans have already performed a speed reduction measure in step S13, so that the current rotation speed is lower than the rated rotation speed; but other individual fans than the fan to be started and the adjacent fan, denoted as peripheral fans, are still at the rated speed. Therefore, in step S14, the adjacent fan and the peripheral fan may be slowed down to the same rotational speed for the first time, so as to perform the subsequent unified speed reduction process.
It should be noted that, by adopting a stepped speed reduction mode, the hot start of the fan to be started can be realized as soon as possible under the condition of reducing the loss of the heat radiation speed as much as possible.
S15: and adjusting all the single fans to a preset rated rotating speed.
After detecting that the fan to be started is successfully started, the rotating speeds of all the single fans (including the fan to be started, the adjacent fan and the peripheral fan) need to be adjusted to the rated rotating speed, so that the fan module can perform a normal heat dissipation procedure by itself.
The hot start method for the fan is suitable for being used for reconnecting and starting the application scene of the fan to be started under the condition that other single fans are not turned off after any fan to be started in the fan module is detached and overhauled, can effectively realize hot start of the fan to be started in the fan module under the condition that the downtime risk is reduced as much as possible, and improves overhauling efficiency and convenience.
Example 2
The embodiment provides a hot start method for a fan, which is suitable for an application scenario that the number of single fans of a fan module is increased and newly-increased single fans are started under the condition that other single fans are not turned off, and can effectively realize hot start of a newly-increased fan in the fan module under the condition that the downtime risk is reduced as much as possible, so that the working efficiency and convenience of capacity expansion are improved.
Referring to fig. 2, the fan warm start method includes:
s21: and judging whether a reserved interface which is not connected exists in the fan module. If yes, the newly added single fan corresponding to the reserved interface is marked as a fan to be started.
Generally, the fan module includes a plurality of single fans, and each single fan is arranged in a matrix, such as a nine-grid arrangement of 3 × 3 or a twenty-four-grid arrangement of 4 × 6. The quick connector is correspondingly arranged at the mounting hole of each single fan, so that the single fans are electrically connected with the quick connector, and then the single fans can be controlled independently or in a centralized manner.
Under the normal condition, all the single fans in the fan module run at the same rated rotating speed, if a certain single fan is disconnected from the electric connection in the working process of the fan module, it can be determined that the single fan corresponding to the mounting hole needs to be overhauled or replaced, no matter the single fan is overhauled and then reconnected to be started, or a new single fan is taken to be connected to be restarted, the single fans subsequently installed in the mounting hole are marked as fans to be started, that is, as long as the quick connector at the mounting hole is disconnected from the electric connection, the single fan subsequently reconnected to the quick connector is the fan to be started.
S22: judging whether the fan to be started is connected or not; if so, sending an instruction for starting the fan to be started; if not, continuously monitoring the connection state;
s23: judging whether the fan to be started is started successfully or not; if yes, go directly to step S25; if not, performing speed reduction treatment on at least one adjacent fan around the fan to be started; and maintaining the rotational speed of the peripheral fan other than the fan to be started and the at least one adjacent fan constant.
It should be noted that, because the individual fans are arranged in a matrix, the individual fans may be arranged in eight directions, such as above, below, left side, right side, above left side, above right side, below left side, and below right side, of the fan to be started.
If the fan to be started is located at the left edge position, only six directions, namely upper direction, lower direction, right direction, upper right direction, lower right direction and the like, exist in the adjacent fan. If the fan to be started is located at the upper edge position, only six directions, namely, the left direction, the lower direction, the right direction, the left lower direction and the right lower direction, exist in the adjacent fan. By analogy, the specific position of the adjacent fan is not described in this embodiment.
In this embodiment, there is only one layer of adjacent fans, that is, in a 3 × 3 squared figure with the fan to be started as the center, the eight individual fans around the center are all adjacent fans. In some other embodiments, the adjacent fans may be two layers, that is, in a 5 × 5 squared grid with the fan to be started as the center, all of the 24 individual fans outside the center are adjacent fans; or, the adjacent fans can be three layers, namely, in a 7 × 7 squared case with the fan to be started as the center, the 48 single fans outside the center are all adjacent fans. Certainly, the adjacent fans can also be four layers, five layers or more, and the specific number of the adjacent fans is not described in detail in this embodiment; generally, the number of adjacent fans is less than the total number of individual fans included in the fan module.
In this embodiment, after detecting that the fan to be started fails to start, the system determines that the reverse flow effect is strong, resulting in the locked-rotor of the fan to be started. Generally, the reverse flow effect of the adjacent fan around the fan to be started is the strongest, so that firstly, considering to reduce the rotating speed of the adjacent fan and even turn off the adjacent fan, a larger reverse flow strength reduction value can be obtained at the expense of smaller heat dissipation speed loss, namely, the influence on the heat dissipation effect of the fan module is not large, but the reverse flow effect can be greatly reduced, so as to be beneficial to the normal starting of the fan to be started.
Of course, in some other embodiments, if the fan to be started fails to start, the number of adjacent fans may be increased, that is, only the first layer (eight) of adjacent fans around the fan to be started is rotated at the beginning; if the starting fails, reducing the rotating speed of the second layer (twenty-four) of adjacent fans at the periphery of the fan to be started; if the start fails, the rotation speed … of the adjacent fan at the third layer (forty-eight) around the fan to be started is reduced, and so on, which is not described in detail in this embodiment.
S24: judging whether the fan to be started is started successfully or not; if yes, go directly to step S25; if not, all the single fans except the fan to be started are subjected to graded speed reduction processing until the fan to be started is started successfully.
If the adjacent fan cannot be started normally after the rotating speed of the adjacent fan is reduced, the current reverse flow effect is still strong, and the reverse flow effect needs to be further reduced. In this embodiment, in order to further reduce the reverse flow effect without completely losing the heat dissipation effect, only the graded speed reduction processing is performed on all the remaining single fans except the fan to be started, and a measure of directly shutting down all the remaining single fans is not taken.

In this embodiment, the rotation speed between the next level and the previous level is in a functional relationship, for example, the rotation speed of the next level is 70% or 60% of the previous level, and the like, that is, the rotation speed of all the single fans is reduced by 30% or 40% each time; alternatively, the next level of rotation speed is 200 revolutions/min less than the previous level of rotation speed, i.e. every time the rotation speed of all the individual fans is reduced by 200 revolutions/min.
Alternatively, the rotation speed of each level is specified by the database, for example, the rotation speed corresponding to each level is directly specified in the database, for example, the first-level rotation speed is specified as the rated rotation speed, the second-level rotation speed is 5000 rpm, and the third-level rotation speed is 4000 rpm.
In this embodiment, before step S24 is taken, there are two rotation speeds for each single fan in the fan module, namely, the adjacent fans are fewer single fans, and the single fans have already performed a speed reduction measure in step S30, so that the current rotation speed is lower than the rated rotation speed; but other individual fans than the fan to be started and the adjacent fan, denoted as peripheral fans, are still at the rated speed. Therefore, in step S24, the adjacent fan and the peripheral fan may be slowed down to the same rotational speed for the first time, so as to perform the subsequent unified speed reduction process.
It should be noted that, by adopting a stepped speed reduction mode, the hot start of the fan to be started can be realized as soon as possible under the condition of reducing the loss of the heat radiation speed as much as possible.
S25: and adjusting all the single fans to a preset rated rotating speed.
After detecting that the fan to be started is successfully started, the rotating speeds of all the single fans (including the fan to be started, the adjacent fan and the peripheral fan) need to be adjusted to the rated rotating speed, so that the fan module can perform a normal heat dissipation procedure by itself.
The embodiment provides a hot start method for a fan, which is suitable for an application scenario that the number of single fans of a fan module is increased and newly-increased single fans are started under the condition that other single fans are not turned off, and can effectively realize hot start of a newly-increased fan in the fan module under the condition that the downtime risk is reduced as much as possible, so that the working efficiency and convenience of capacity expansion are improved.
