Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
It is worth noting that power supply system described in the embodiment of the present invention is communication network power supply system, such as standard PoE
Power supply system, nonstandard PoE power supply system etc..Then the feeder ear be standard PoE feeder ear or non-standard PoE feeder ear, it is described
Receiving end is standard PoE receiving end or non-standard PoE receiving end.
It is a kind of structural schematic diagram of power supply system provided in an embodiment of the present invention referring to Fig. 1, Fig. 1；It include: feeder ear 10
With receiving end 20, the feeder ear 10 includes the first main control module 11, measurement register 12 and power-supplying interface module 13, it is described by
Electric end 20 is including the second main control module 21, actual loading 22 and by electrical interface module 23；Wherein, first main control module 11 divides
The measurement register 12 and the power-supplying interface module 13 are not connected, and the measurement register 12 connects the power supply interface mould
Block 13, the power-supplying interface module 13 connect described by electrical interface module 23；Second main control module 21 is separately connected described
Actual loading 22 and described by electrical interface module 23, the actual loading 22 connect described by electrical interface module 23.
Second main control module 21, for judging whether the feeder ear 10 supports power measurement；If so, when described
Actual loading 22 supports work in controllable power consumption mode, enables the actual loading 22, so that the actual loading 22 works
In controllable power consumption mode, and sends power measurement and instruct to first main control module 11；If it is not, then keeping working normally shape
State.
First main control module 11, for controlling the measurement register when receiving power measurement instruction
12, which record the power-supplying interface module 13, is transferred to the power information by electrical interface module 23.
When the feeder ear 10 establishes a connection with the receiving end 20, the feeder ear 10 starts to supply electricity to described
Receiving end 20.It should be noted that the feeder ear 10 is not always on power measurement in power supply process, but periodically
Or other necessary moment open power measurements, therefore, the receiving end 20 is firstly the need of judging whether the feeder ear 10 props up
Power measurement is held, the receiving end 20 can send inquiry instruction to the feeder ear 10, to inquire the feeder ear 10 at this time
Whether support power measurement, and instructs judgement to supply according to the response when receiving the response instruction that the feeder ear 10 returns
Whether power measurement is supported in electric end 10.
When the feeder ear 10 supports power measurement, and when the actual loading 22 supports work in controllable power consumption mode
When, second main control module 21 enables the actual loading 22, so that the actual loading 22 works in controllable power consumption mode,
And it sends power measurement and instructs to first main control module 11.First main control module 11 receives the power measurement and refers to
When enabling, the control measurement register 12 records the power-supplying interface module 13 and is transferred to the power by electrical interface module 23
Information.Illustratively, the power information includes at least one of information of voltage and current information.First main control module
11 record the power information by controlling the measurement register 12, learn the power service condition of the receiving end 20, from
And system power can be allocated and be managed, anti-locking system power load exceeds.
Optionally, first main control module 11 controls the measurement register 12 and records the biography of power-supplying interface module 13
It is defeated by the power information by electrical interface module 23, is specifically included:
Measurement sign on is sent to second main control module 21；
Control the measurement register 12 record the power-supplying interface module 13 be transferred to it is described by electrical interface module 23
Power information；
When meet it is preset be measured condition when, send measurement END instruction to second main control module 21 so that
The receiving end 20 restores normal operating conditions.
Illustratively, when the receiving end 20 confirms that the feeder ear 10 supports power measurement, the second master control mould
Block 21 sends power measurement and instructs to the feeder ear 10, so that the feeder ear 10 confirms that the receiving end 20 has been prepared for
Report power.The feeder ear 10 sends measurement sign on to second main control module 21, to inform the receiving end 20
It is starting to measure the power-supplying interface module 13 and is being transferred to the power information by electrical interface module 23.
Illustratively, the condition that is measured includes:
The feeder ear 10 after receiving the receiving end 20 and sending power measurement instruction, in the first preset time period into
Row 100ms slides measurement window and calculates power average value；Taking the maximum value in the power average value is the receiving end 20
Power is measured, at this point, being measured；Wherein, first preset time period is 3s；
Alternatively, the feeder ear 10 is after receiving the receiving end 20 and sending power measurement instruction, in the first preset time
The power measurement of random number is carried out in section；Integral power time of measuring duty ratio is not less than 50% performance number, and takes described
The measurement power of receiving end 20 described in the power that maximum value in performance number is, at this point, being measured.
Optionally, the receiving end 20 further includes power analog generator 24, and the power analog generator 24 connects respectively
Connect second main control module 21 and described by electrical interface module 23；Then, second main control module 21, is specifically used for:
Judge whether the feeder ear 10 supports power measurement；
If so, the actual loading 22 is enabled when the actual loading 22 supports work in controllable power consumption mode, with
Make the work of actual loading 22 in controllable power consumption mode, and closes the power analog generator 24；Or, working as the actual negative
Carrying 22 does not support work in controllable power consumption mode, enables the power analog generator 24, so that the power analog occurs
Device 24 works under predetermined power state, and controls the work of actual loading 22 under minimum power consumption mode；If it is not, then keeping
Normal operating conditions；
When the feeder ear 10 supports power measurement, sends power measurement and instruct to first main control module 11.
Specifically, the power analog generator 24 be can be it is a kind of specific, power receiving equipment power and symbol can be simulated
Power draw device/the module for closing system power tolerance, is also possible to a kind of steady operation shape that can characterize equipment feature power
State, such as can be the simple integrated of very simple cement load, high-power resistor or high power MOSFET, the power drawn
Correspondence power of the actual loading 22 under each power rating mode should be not less than.When work is not supported in the actual loading 22
Make in controllable power consumption mode, because, being difficult directly to close the actual loading 22 in systems in practice, this is related to rear class system
Power-on and power-off problem, control complexity of getting up is very high, therefore using the power consumption for maintaining and reducing to the greatest extent the actual loading 22
Mode is more practical.While opening power analog generator 24, the actual loading 22 of low-power is continued to
Operation, the power data surplus that the feeder ear 10 measures can be promoted.
Further, referring to fig. 2, Fig. 2 is the structural schematic diagram of another power supply system provided in an embodiment of the present invention.
