Abstract
The invention relates to an overcurrent protection device for a four-way server. The overcurrent protection device is characterized by comprising a Pmbus address unit arranged on a PSU power module, the Pmbus address unit is connected with a detection unit through an I2C bus, a current comparator is arranged inside the detection unit which is connected with a control unit, and the control unit controls the PUS power module to be switched on or off.
Description
Technical field
The invention belongs to server technology field, relate to overcurrent protective device and the method for a kind of four road servers.
Background technology
Server is also referred to as servomechanism, is to provide the equipment of the service of calculating；Owing to server needs response service request, go forward side by side
Row processes, and the most in general server should possess the service of undertaking and ensure the ability of service.Server is by system frame at present
Structure is divided into non-X86 server and X86 server, is divided into entry level by application level, and work level, department level, enterprise-level；By CPU
Quantity can be divided into low side two-way, middle-end four tunnel, high-end eight tunnels etc., is widely used in government, bank, finance, railway, medium-sized and small enterprises
Deng；Wherein the share of four road servers is especially prominent at server market.
Along with enterprise's fast development of different scales, enterprise needs business datum to be processed the most gradually to increase, and thus wants
Enterprise is asked to need the server using specialty to help to process these data.All trades and professions are widely used server and make it to can
By property, security requirement is the highest, especially can not occur the phenomenon of burning machine during user uses server.Sending out of burning machine
At power input or outfan, raw being usually occurs in that short circuit causes the generation of big electric current thus burns components and parts, severe patient
There will be naked light.
Four road server computing boards need not warm connection function, so need not soft start switch at input, at some
Under specific input or load end short-circuit conditions, unprotected circuit on computing board, it is easy for occurring burning components and parts even
The phenomenon of naked light.In place of this is the deficiencies in the prior art.
Therefore, for drawbacks described above of the prior art, it is provided that design a kind of four road servers overcurrent protective device and
Method, to solve above-mentioned technical problem, is necessary.
Summary of the invention
It is an object of the invention to, the defect existed for above-mentioned prior art, it is provided that design a kind of four road servers
Overcurrent protective device and method, to solve above-mentioned technical problem.
For achieving the above object, the present invention provides techniques below scheme:
A kind of overcurrent protective device of four road servers, it is characterised in that: it includes the Pmbus ground being arranged at PSU power module
Location unit, described Pmbus address location connects detecting unit by I2C bus, is provided with current ratio in described detecting unit
Relatively device, described detecting unit connects control unit, and described control unit controls the break-make of PUS power module.
The over-current protection method of a kind of four road servers, comprises the following steps:
Step 1): distribute Pmbus address location on PSU power module；
Step 2): the output electric current of PSU power supply, and the current value that will be obtained by I2C bus is obtained by Pmbus address location
Send to detecting unit；
Step 3): by the current comparator in detecting unit, the current value sent is compared, if being more than preset value,
Then detecting unit sends closedown PSU power module signal to control unit, and control unit closes PSU power module.
The beneficial effects of the present invention is, obtained the output current value of PUS power supply by Pmbus address location, and to this
Current value contrasts, if beyond electric current preset value (threshold value), then controls PSU power module by control unit and closes, real
The now overcurrent protection to server.Additionally, design principle of the present invention is reliable, simple in construction, before having application widely
Scape.
As can be seen here, the present invention compared with prior art, has prominent substantive distinguishing features and improves significantly, and it is implemented
Beneficial effect be also apparent from.
Accompanying drawing explanation
Fig. 1 is the structural representation of the overcurrent protective device of a kind of four road servers that the present invention provides.
Wherein, 1-PSU power module, 2-Pmbus address location, 3-detecting unit, 4-current comparator, 5-controls single
Unit.
Detailed description of the invention
The present invention will be described in detail below in conjunction with the accompanying drawings and by specific embodiment, and following example are to the present invention
Explanation, and the invention is not limited in implementation below.
As it is shown in figure 1, the overcurrent protective device of a kind of four road servers of present invention offer, it includes being arranged at PSU electricity
The Pmbus address location 2 of source module 1, described Pmbus address location 2 connects detecting unit 3, described detecting by I2C bus
Being provided with current comparator 4 in unit 3, described detecting unit 3 connects has control unit 5, described control unit 5 to control PUS electricity
The break-make of source module 1.
The present invention gives the over-current protection method of a kind of four road servers, comprises the following steps:
Step 1): distribute Pmbus address location on PSU power module；
Step 2): the output electric current of PSU power supply, and the current value that will be obtained by I2C bus is obtained by Pmbus address location
Send to detecting unit；
Step 3): by the current comparator in detecting unit, the current value sent is compared, if being more than preset value,
Then detecting unit sends closedown PSU power module signal to control unit, and control unit is closed PSU power module, otherwise forwarded to
Step 2).
Only the preferred embodiment of the present invention disclosed above, but the present invention is not limited to this, any this area
What technical staff can think does not has a creative change, and the some improvement made without departing from the principles of the present invention and
Retouching, all should be within the scope of the present invention.
