The short-circuit conditions of one power supply link are monitored automatically, therefore the embodiment of the present invention can be improved and carry out short-circuit prison to power supply link
The simplification of control.
In detail, by the way that each monitoring link is connected in series with corresponding power supply link, so that under normal circumstances, passing through monitoring
The electric current of link is identical as the electric current by corresponding power supply link.In this way, when power supply link is there are when short-circuit conditions, monitoring chip
The current status monitored will be inconsistent with predetermined standard state.
For example, if the numerical value of the electric current monitored is more than corresponding given threshold, it may be said that bright corresponding power supply link occurs short
Road；If the numerical value of the electric current monitored is consistent with corresponding given threshold, or is not much different, it may be said that bright corresponding power supply link is not deposited
In short-circuit conditions.
In detail, in an embodiment of the invention, after completing short circuit monitoring to each power supply link, monitoring chip can be with
The switch controlled in each monitoring link disconnects, in this way, the presence of monitoring chip and each monitoring link can not influence board just
It is often used.
In detail, board, i.e. pcb board have been generally included a plurality of on board for the power demands for meeting different electrical equipments
Power supply link, wherein the supply voltage of difference power supply links is different.For example, respectively power supply link supply voltage can be respectively+
5V ,+3.3V ,+1.8V ,+1.2V etc..
Therefore, in an embodiment of the invention, referring to FIG. 2, it is described at least one power supply link 101 in any confession
The supply voltage on current source road is one of+5V ,+3.3V ,+1.8V ,+1.2V.

In detail, it is based on above content, due to that can have a plurality of power supply link, and the power supply electricity of each power supply link on board
Pressure is different, therefore equally can integrate power supply module on board, accordingly to be converted to the supply voltage that external power supply provides.
For example, the supply voltage of external power supply output can be+12V, power module, can be by its point through internal voltage conversion circuit
+ 5V ,+3.3V ,+1.8V ,+1.2V are not converted to, and are exported respectively to corresponding power supply link, to supply corresponding electrical equipment
Electricity.

It is execution abnormality processing, including：Acquire the partial pressure of the first resistor in the monitoring link, wherein described to divide and pass through institute
The electric current for stating monitoring link is proportional；Judge whether the partial pressure is located within the scope of preset respective threshold, if it is not, determining
The corresponding power supply link short circuit of the monitoring link, and execute abnormality processing.
