Description
Technical field
The invention belongs to server cabinet field of safety protection, and in particular to plate part failure power down protection in a kind of node
Device and guard method.
Background technology
With the fast development of the Networks such as internet, server starts in many field extensive uses, in server
In system, plate is indispensable pith in node, and it is that rack node is powered board in storage class application, to protect
Card node normally works.And increasing with number of nodes, the demand current of the 12V that powered to plate in node is bigger；Meanwhile, use
Requirement of the family to the on-line maintenance of plate in node is also improved constantly.
At present, in Rack rack server systems, in node plate from after power taking on whole machine cabinet copper bar, then through overvoltage
Conversion chip ensures voltage stabilization, then is powered to node.When system is powered, plate in node is inserted on whole machine cabinet copper bar, meeting
Larger transient current is produced to pass through connector.
Meanwhile, the equivalent inductance in node above plate Copper Foil is larger, and transient current can produce reverse induction voltage, when in section
Plate input in point, when there is negative voltage, the negative voltage can cause input capacitance, MOS or hot plug chip pin beyond safety
Pressure-resistant scope and damage.Once the part in node in plate burns out failure, necessarily cause plate short circuit in node, then cause whole
Rack power down, it is impossible to normal work.This is the deficiencies in the prior art part.
The content of the invention
It is an object of the present invention to be directed to the defect that above-mentioned prior art is present, there is provided plate part in a kind of node of design
Failure power-down protection apparatus and guard method, to solve above-mentioned technical problem.
To achieve the above object, the present invention provides following technical scheme：

Cross fuse and be electrically connected to conducting copper, current sensor is additionally provided with the wire between fuse and conducting copper, it is described
Current sensor be connected with microcontroller, described microcontroller is connected with remote alarming module, described remote alarms mould
Block is communicated by wireless network with intelligent terminal.
Preferably, described wireless network is GPRS network or wifi network.
Preferably, described fuse is glass tubular fuse.
Preferably, described current sensor is HBA-YSB Hall current sensors.
Preferably, described microcontroller is singlechip controller.
Plate part failure power-off protection method in a kind of node, it is characterised in that comprise the following steps：
Step 1）：Simulation input terminal shortcircuit, time and maximum current according to rack power supply trigger protection, produces when calculating hot plug
Raw energy；
Step 2）：Current value and rack power protection time according to test, select the fuse of appropriate size, it is ensured that its is normal
Bear current capacity and excessively stream the reaction time meets current design needs；
Step 3）：Fuse is set between plate and conducting copper in node.
The beneficial effects of the present invention are by setting fuse, it is to avoid cause section due to plate part failure in node
In point plate short circuit, then influence rack cannot normal work situation.Simultaneously by setting current sensor, can detect constantly
Whether fuse fuses, and when blown fuse, is alarmed by remote alarming module.Additionally, design principle of the present invention can
Lean on, simple structure, with application prospect widely.
As can be seen here, the present invention compared with prior art, improves with prominent substantive distinguishing features and significantly, and it is implemented
Beneficial effect be also obvious.
