Embodiment
For the technical problem that background technique is mentioned, the invention provides the blower module controlling method in a kind of new dual control storage system.This method avoid a memory controller when breaking down, the system radiating problem that its fan originally controlled is in runaway condition and brings; And the method, while solution heat dissipation problem, solves the few problem of fan gear with lower cost.Describe in detail below by way of embodiment.
Please refer to the drawing 3, Fig. 3 is that the blower module of embodiment of the present invention dual control storage system controls schematic diagram.This dual control storage system comprises: memory controller A, memory controller B, the blower module a corresponding with memory controller A and the blower module b corresponding with memory controller B.In the embodiment of the present invention, memory controller A and memory controller B controls respectively to blower module a and blower module b no longer individually, but memory controller A both can control blower module a, also can control blower module b; Similarly, memory controller B both can control blower module a, also can control blower module b.When specific implementation, by increasing by a backboard in this dual control storage system, and arrange a logic chip on this backboard, such as complex programmable logic chip CPLD reaches arbitrary memory controller simultaneously to the object that blower module a and blower module b controls.
The temperature that memory controller A responds to according to temperature transducer T1, send rotation speed of the fan class command to backboard, backplane logic chip sends corresponding rotation speed of the fan control signal according to this rotation speed of the fan class command and carries out the rotation of corresponding speed to blower module a and blower module b, this blower module a and blower module b according to aforementioned control signals.
The temperature that memory controller B responds to according to another temperature transducer T2, send rotation speed of the fan class command to backboard, backplane logic chip sends corresponding rotation speed of the fan control signal according to this rotation speed of the fan class command and carries out the rotation of corresponding speed to blower module a and blower module b, this blower module a and blower module b according to aforementioned control signals.
Memory controller A and memory controller B is separate when sending rotation speed of the fan class command according to respective temperature sensor senses temperature.In addition, a rotation speed of the fan class command of memory controller A can realize the control to blower module a and blower module b simultaneously; A rotation speed of the fan class command of memory controller B also can realize the control to blower module a and blower module b simultaneously.Like this, after memory controller A breaks down, memory controller B is when sending rotation speed of the fan class command according to the temperature sensor senses temperature of oneself, this order can realize the control to blower module a, blower module a so just can be avoided to be in uncontrollable state and the too high problem of the system temperature caused.
Here any is had to it should be noted that, be in the blower module a in a system and blower module b, the much the same rotating speed of usual use carries out system radiating, and the temperature transducer that namely memory controller A is corresponding and the general difference of temperature that temperature sensor senses corresponding to memory controller B arrives can not be very large.Control two blower modules be fine so the rotation speed of the fan class command of a memory controller changes into corresponding control signal with during same rotational speed, can not the heat radiation of influential system.
Rotation speed of the fan class command can carry multiple rotation speed of the fan.If the rotating speed of 3 grades supported by such as fan, then can represent rotation speed of the fan grade 1 with rotation speed of the fan class command 01, represent rotation speed of the fan grade 2 with 10, represent rotation speed of the fan grade 3 with 11.In addition, do-nothing operation can also be represented with rotation speed of the fan class command 00.Such as, memory controller A have sent the rotation speed of the fan class command of a do-nothing operation, after backplane logic chip receives this order, do not issue control signal to blower module a and blower module b, in the register of oneself, just record the information of " maintaining current rotating speed ".Memory controller can send the rotation speed of the fan order of concrete grade to backplane logic chip, and after backplane logic chip performs this rotation speed of the fan class command, memory controller issues the rotation speed of the fan class command of this do-nothing operation again to backplane logic chip.
Provide the example of a backplane logic chip to the fan class command ruling that memory controller A and memory controller B provides below.
State:initial represents original state, can be preset as 11;
State:A represents that the rotating speed of current blower module is regulated by memory controller A;
State:B represents that the rotating speed of current blower module is regulated by memory controller B.
If current blower module state is State:initial, if memory controller A issues do-nothing operation to backplane logic chip, then blower module remains State:initial.
If current blower module state is State:initial, memory controller B issues do-nothing operation to backplane logic chip, then blower module remains State:initial.
If current blower module state is State:initial, memory controller A issues non-do-nothing operation to backplane logic chip, then blower module control is attributed to State:A.
If current blower module state is State:initial, memory controller B issues non-do-nothing operation to backplane logic chip, then blower module control is attributed to State:B.
If current blower module state is State:A, memory controller B issues non-do-nothing operation to backplane logic chip, then blower module control is attributed to State:B.
If current blower module state is State:B, memory controller A issues non-do-nothing operation to backplane logic chip, then blower module control is attributed to State:A.
A bit need explanation in addition, if while memory controller A sends rotation speed of the fan class command to backboard according to the temperature of temperature sensor senses, memory controller B sends rotation speed of the fan class command to backboard according to the temperature of another temperature sensor senses, and backplane logic chip can select arbitrarily an order first to perform.Particularly, the rotation speed of the fan class command that backplane logic chip can first send according to memory controller A sends corresponding rotation speed of the fan control signal to blower module a and blower module b, the rotation speed of the fan class command of correspondence sent according to memory controller B again sends corresponding rotation speed of the fan control signal carries out corresponding speed respectively according to control signal rotation to blower module a and blower module b, blower module a and blower module b; Or, the rotation speed of the fan class command that backplane logic chip can also first send according to the second storage controller B sends corresponding rotation speed of the fan control signal to blower module a and blower module b, then sends corresponding rotation speed of the fan control signal to blower module a and blower module b according to the rotation speed of the fan class command that memory controller A sends; Blower module a and blower module b carries out the rotation of corresponding speed respectively according to control signal.
The embodiment of the present invention achieves the rotating speed of many gears fan in a kind of simple, cheap mode, and when particular avoid a controller failure, its blower module controlled is in the system radiating problem that uncontrollable state is brought.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within the scope of protection of the invention.
