Embodiment
The technical problem mentioned for background technology, the present invention provides the blower module in a kind of new dual control storage system Control method.When being broken down this method avoid storage control, the fan of its script control be in runaway condition and The system radiating problem brought;And this method solves fan gear while heat dissipation problem is solved with relatively low cost Few the problem of.Described in detail below by way of embodiment.
It please join Fig. 3, Fig. 3 is the blower module control schematic diagram of dual control storage system of the embodiment of the present invention.The dual control is stored System includes:Storage control A, storage control B, blower module a corresponding with storage control A and with storage control B Corresponding blower module b.In the embodiment of the present invention, storage control A and storage control B are no longer individually to blower module a It is respectively controlled with blower module b, but storage control A can both control blower module a, can also control blower module b;Similarly, storage control B is also that can both control blower module a, can also control blower module b.Implement when Wait, by increasing by a backboard in the dual control storage system, and a logic chip, such as complex programmable are set on the backboard Logic chip CPLD reaches purpose that any storage control is controlled blower module a and blower module b simultaneously.
The temperature that storage control A senses according to temperature sensor T1, sends rotation speed of the fan class command to backboard, backboard Logic chip sends corresponding rotation speed of the fan control signal to blower module a and blower module according to the rotation speed of the fan class command B, blower module a and blower module b carry out the rotation of corresponding speed according to aforementioned control signals.
The temperature that storage control B senses according to another temperature sensor T2, sends rotation speed of the fan class command to backboard, Backplane logic chip sends corresponding rotation speed of the fan control signal to blower module a and fan according to the rotation speed of the fan class command Module b, blower module a and blower module b carry out the rotation of corresponding speed according to aforementioned control signals.
Storage control A and storage control B is sending rotation speed of the fan etc. according to respective temperature sensor senses temperature It is separate when level order.In addition, a storage control A rotation speed of the fan class command can be realized pair simultaneously Blower module a and blower module b control;A storage control B rotation speed of the fan class command can also be realized pair simultaneously Blower module a and blower module b control.So, after storage control A breaks down, storage control B is according to oneself Temperature sensor senses temperature send rotation speed of the fan class command when, the order can realize the control to blower module a, so Just be avoided that blower module a be in uncontrollable state caused by system temperature it is too high the problem of.
Here have a little it should be noted that blower module a in a system and blower module b, usually used Much the same rotating speed carries out system radiating, the i.e. corresponding temperature sensors of storage control A and the corresponding temperature of storage control B The general difference of temperature that degree sensor sensing is arrived will not be very big.So the rotation speed of the fan class command of a storage control turns Being melted into when corresponding control signal controls two blower modules with same rotational speed is possible, and does not interfere with dissipating for system Heat.
Rotation speed of the fan class command can carry a variety of rotation speeds of the fan.If for example fan supports the rotating speed of 3 grades, can To represent rotation speed of the fan grade 1 with rotation speed of the fan class command 01, rotation speed of the fan grade 2 is represented with 10, represents that fan turns with 11 Fast grade 3.In addition to this it is possible to represent do-nothing operation with rotation speed of the fan class command 00.Such as, storage control A is sent The rotation speed of the fan class command of one do-nothing operation, backplane logic chip is received after the order, and control signal is not issued to fan Module a and blower module b, the information for simply " maintaining current rotating speed " described in the register at oneself.Storage control can be with Backplane logic chip is given in the rotation speed of the fan order for sending specific grade, and backplane logic chip performs the rotation speed of the fan grade After order, the rotation speed of the fan class command that storage control issues the do-nothing operation again gives backplane logic chip.
The fan class command that a backplane logic chip is provided to storage control A and storage control B is given below One example of ruling.
State:Initial represents original state, can be preset as 11;
State:A represents that the rotating speed of current blower module is adjusted by storage control A;
State:B represents that the rotating speed of current blower module is adjusted by storage control B.
If current blower module state is State:Initial, if storage control A issues do-nothing operation to backplane logic Chip, then blower module remain State:initial.
If current blower module state is State:Initial, storage control B issues do-nothing operation and gives backplane logic core Piece, then blower module remain State:initial.
If current blower module state is State:Initial, storage control A issue non-do-nothing operation to backplane logic Chip, then blower module control be attributed to State:A.
If current blower module state is State:Initial, storage control B issue non-do-nothing operation to backplane logic Chip, then blower module control be attributed to State:B.
If current blower module state is State:A, storage control B issues non-do-nothing operation and gives backplane logic chip, Then blower module control is attributed to State:B.
If current blower module state is State:B, storage control A issues non-do-nothing operation and gives backplane logic chip, Then blower module control is attributed to State:A.
If more also it is to be appreciated that storage control A sends rotation speed of the fan according to the temperature of temperature sensor senses While class command is to backboard, storage control B sends rotation speed of the fan grade according to the temperature of another temperature sensor senses Backboard is ordered, backplane logic chip can arbitrarily select an order to first carry out.Specifically, backplane logic chip can first root The rotation speed of the fan class command sent according to storage control A come send corresponding rotation speed of the fan control signal to blower module a and Blower module b, corresponding rotation speed of the fan control is sent further according to the corresponding rotation speed of the fan class command of storage control B transmissions Signal processed carries out corresponding speed according to control signal respectively to blower module a and blower module b, blower module a and blower module b Rotation;Or, backplane logic chip first can also be sent according to the rotation speed of the fan class command of the second storage controller B transmissions Corresponding rotation speed of the fan control signal is to blower module a and blower module b, the rotation speed of the fan sent further according to storage control A Class command sends corresponding rotation speed of the fan control signal to blower module a and blower module b;Blower module a and fan mould Block b carries out the rotation of corresponding speed according to control signal respectively.
The embodiment of the present invention realizes the rotating speed of many gear fans in a kind of simple, cheap mode, especially keeps away When having exempted from a controller failure, its blower module controlled is in the system radiating problem that uncontrollable state is brought.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention God is with principle, and any modification, equivalent substitution and improvements done etc. should be included within the scope of protection of the invention.
