Description

A method of being applied to anti-short circuit and the quick diagnosis short circuit of server
Technical field
The present invention relates to server testing fields, and in particular to a kind of anti-short circuit and quick diagnosis applied to server is short The method on road.
Background technology
Server master board size is big at present, circuit is more, and using the power supply of various voltage values, this leads to power circuit time The entire mainboard of cloth causes motherboard circuit short-circuit once maloperation occurs, and diagnosis is got up extremely difficult.If it is non-complete to encounter circuit Dead-short-circuit, it can be relatively easily diagnosed to be short-circuit place by being segmented detection, or by observing the copper foil cabling on mainboard Whether there is apparent damage that can also be diagnosed.But if entire mainboard all large area dead short, for example it is to pull up The electricity used is much connected with filter capacitor over the ground, if such case is short-circuit, thousands of members are had on possible mainboard Part is very difficult to be diagnosed at this time.
Present server uses the output end in power supply to add PolySwitch (self-recovery fuse) or make Power supply VR has OCP (Overcurrent Protection, overload protection) functions to solve the problems, such as this, when short circuit occurs Overcurrent protection will occur in the case of current overload.But motherboard power supply not all at present all adds PolySwitch, and the detection on mainboard for power supply is not comprehensive, when having short circuit to occur, can not directly find out Short-circuit power supply, it is also necessary to carry out auxiliary judgment with voltmeter, heavy workload and expend time and manpower.
In view of the above-mentioned problems, a kind of method of anti-short circuit and quick diagnosis short circuit applied to server of the present application, The power supply of short circuit can occur with accurate judgement for this method, carry out open circuit protection in time, while can be accurately positioned short-circuit power supply, and When be accurately diagnosed to be the power supply to break down, substantially increase diagnosis efficiency.
Invention content
The main of the present invention is achieved in that each branch in power supply adds PolySwitch, each The front and back addition supply voltage of PolySwitch monitors, and electric current moment overload can occur when short circuit occurs for mainboard, this When, PolySwitch will trigger protection generate open circuit, to prevent short-circuit generation.
Specifically, a kind of method of anti-short circuit and quick diagnosis short circuit applied to server is claimed in the application, It is characterized in that, this method specifically includes:
According to the corresponding PolySwitch of each power supply of the normative choice of voltage and current;
Increase the detecting voltage point of corresponding power in the front-end and back-end of each PolySwitch;
The sense terminal of detecting voltage point is connected to CPLD;
The pin of CPLD carries out short-circuit judgement by detecting the level of each detecting terminal voltage, if a power supply There is voltage in the front end of PolySwitch and rear end does not have, then it is assumed that is that short circuit has occurred, it is corresponding that CPLD will control the power supply The trouble light of power supply indicator instruction short circuit.
The method of anti-short circuit and quick diagnosis short circuit as described above applied to server, it is further characterized in that, when The voltage that CPLD is detected carries out voltage division processing when being higher than pin pressure resistance range.
The method of anti-short circuit and quick diagnosis short circuit as described above applied to server, it is further characterized in that, CPLD It is the sequencing for judging power supply according to the timing requirements of power supply, controls the event of the corresponding power supply indicator instruction short circuit of the power supply Hinder lamp.
Description of the drawings

Specific implementation mode
(Complex Programmable Logic Device are complicated using CPLD for the server master board power supply of the present invention Programmable logic device) master controller as power detecting and control, respectively adds a voltage before and after PolySwitch Point is detected, the pin of CPLD carries out short-circuit judgement by detecting the level of each voltage, if the front end of PolySwitch has Electric rear end is not considered then that short circuit has occurred;Voltage division processing is then carried out when voltage is higher than pin pressure resistance range.CPLD The sequencing of power supply is judged according to the timing requirements of power supply, if triggering protection there are one power supply, CPLD will be controlled pair The power supply indicator answered indicates the trouble light of short circuit, thus can timely and accurately be diagnosed to be the power supply to break down.
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with the drawings and specific embodiments pair The present invention, which is done, to be further described in detail:
In the circuit design process of server master board, each power supply has the design specification of voltage and current.
1, according to the corresponding PolySwitch of each power supply of the normative choice of voltage and current;
2, increase the detecting voltage point of corresponding power in the front-end and back-end of each PolySwitch, specific connection type is such as Shown in attached drawing 1;
3, the sense terminal of detecting voltage point is connected to CPLD (being not shown in attached drawing 1);
4, CPLD controls the corresponding bright malfunction indicator lamp of LED control pipes pin point after detecting short-circuit power supply, and control circuit is such as Shown in attached drawing 2.
When server works, the pin of CPLD is sentenced by detecting the level of each detecting terminal voltage to carry out short circuit Disconnected, if there is voltage in the front end of PolySwitch, rear end does not have, then it is assumed that is that short circuit has occurred;When the voltage detected is higher than Voltage division processing is then carried out when pin pressure resistance range.
CPLD judges the sequencing of power supply according to the timing requirements of power supply, if triggering protection there are one power supply, CPLD will control the trouble light of the corresponding power supply indicator instruction short circuit of the power supply.
As described above, connection type shown in 1 is configured each power supply with reference to the accompanying drawings, it will be able to prevent in power supply Continue to damage the element of corresponding line after short circuit, at the same can also quick diagnosis to go out be which power supply there is a problem.
It should be evident that illustrated above is only the specific embodiment of the present invention, for the common skill in this field For art personnel, without creative efforts, other technical solutions can also be obtained according to above-described embodiment, And the equivalent variations made within the protection scope of the present invention should all be fallen within the scope of protection of the present invention, and belong to the present invention The range of protection.
In conclusion the method for anti-short circuit and quick diagnosis short circuit of the present invention, passes through the output in each power supply End increases PolySwitch, and adds power supply monitoring point in the front and back end of PolySwitch to judge short circuit line, is preventing Short circuit can also rapidly and accurately be diagnosed to be short circuit line while harm, and the failure for substantially increasing server master board power supply is examined Disconnected efficiency.
