Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flowchart of a method for controlling multiple power supply inputs by a powered device according to an embodiment of the present invention. The method for controlling the multi-power-supply input by the power receiving equipment comprises the following steps:
s10, obtains the current maximum power supply amount information of at least two power supply apparatuses that supply power to the own power receiving apparatus, and obtains the current power reception target amount information of the own power receiving apparatus.
Wherein the maximum power supply information includes a maximum power supply current or a maximum power supply power, and the power reception target amount information includes a power reception target current or a power reception target power.
And S11, based on the maximum power supply amount information and the power reception target amount information, allocating power supply input amounts of the at least two power supply apparatuses such that the power supply input amounts of the at least two power supply apparatuses to the own power reception apparatus are smaller than the respective maximum power supply amounts, and such that the power supply input ratios of the at least two power supply apparatuses to the own power reception apparatus are the same. The power supply input ratio comprises one of the following: the ratio of the supply current to the maximum supply current of the power supply apparatus, and the ratio of the supply power to the maximum supply power of the power supply apparatus.
In step S10, the maximum power supply amount information and the power reception target amount information obtained by the power receiving apparatus are obtained to ensure that the input draw ratios of the power supplying apparatuses are equal. After the information of the power receiving target amount is obtained, the power supply equipment can be uniformly allocated according to the actual power demand of the power receiving equipment by combining the maximum power supply amount information of each power supply equipment, so that the power supply input proportion of each power supply equipment is the same. For example, if the maximum value of the supply current of the a-line power supply device is 1A, the supply current of the B-line power supply device is 2A, and the current drawn by the actual powered device during normal operation is 1.5A, the controller controls the powered device to draw 0.5A of the current of the a-line power supply device and 1A of the supply current of the B-line power supply device according to the policy of equal current draw ratio. The current value of the A path is 50% of the maximum power supply current, the power supply current of the B path is 50% of the maximum power supply current, the proportion is the same, the pressure born by the two paths of power supply equipment is the same relative to the pressure born by the two paths of power supply equipment, and the condition that a certain power supply equipment is overloaded is avoided.
The power supply input proportion is the same, so that the service life and the reliability of the power supply equipment can be improved to the maximum extent. Generally, the life of the power supply device and the output power are inversely proportional to each other in a certain time, that is, the larger the power of the power supply output, the lower the life of the power supply device; the smaller the average output power of the power supply equipment working for a long time, the longer the service life of the equipment. The strategy of ensuring that the power supply input proportions of all paths of power supply equipment are equal can effectively prolong the service life of all paths of power supply equipment, in other words, the problem of whole power supply paralysis caused by the fact that the service life of one path of power supply equipment is firstly terminated can be solved, because the power supply pressure born by each path of power supply equipment is the same relative to the power supply pressure born by each path of power supply equipment, as long as the maximum power supply quantity added by the maximum power supply quantity of all the power supply equipment is larger than the target quantity required by the power receiving equipment, the 100% load condition of a certain path of power supply equipment.
Further, the larger the margin of the output power of the supply power with respect to the maximum output power, the higher the reliability thereof. For example: if the output power of the power supply is more distant from the maximum output power thereof by a larger margin, the temperature stress and the current stress of the internal components of the power supply apparatus thereof are smaller, and the reliability thereof is correspondingly higher. Therefore, in practical operation, it is better to ensure that the sum of the maximum power supply amounts of all the power supply apparatuses is much larger than the target amount required by the power receiving apparatus.
In summary, in the embodiment of the present invention, by controlling the power supply apparatuses with the same input power ratio or the same input current ratio, the power supply input ratios of the power supply apparatuses are ensured to be equal, so that the power supply pressures borne by the power supply apparatuses of each path are the same, thereby avoiding the influence on the service life and reliability of some power supply apparatuses due to the excessively high power supply pressures of the power supply apparatuses, and the power supply input ratios of the power supply apparatuses of each path to the power receiving apparatus are equal, so that the power receiving apparatus can reasonably draw the power supply of each power supply apparatus. In summary, the embodiments of the present invention can solve the problems that the power supply methods for different power supply powers in the prior art cannot reasonably draw the maximum total power of multiple paths thereof, and cannot ensure the service life and reliability of the power supply device
For example, in step S11, the allocating power supply input amounts of at least two of the power supply devices specifically includes:
and S110, acquiring the current power supply input current of each detected power supply device to the power receiving device.
And S111, controlling the power supply input of each power supply device to the power receiving device according to the current power supply input current so that the current power supply input current of each power supply device is smaller than the respective maximum power supply current.
In this embodiment, the control strategy for the input of the supply current of each power supply device is closed-loop control, that is, the input of the power supply circuit of the line is continuously adjusted by continuously detecting the power supply input of the line to limit the power supply input to be lower than the maximum input of the power supply device of the line, and the power supply input ratio is ensured to be the same. The scheme of the closed-loop control mechanism is not limited, for example, PI control is adopted.
Exemplarily, the step S10 includes:
s100, receiving handshake signals sent by at least two power supply devices.
The handshake signals comprise maximum power supply information of corresponding power supply equipment;
and S101, analyzing the handshake signals to acquire the maximum power supply amount information of at least two power supply devices.
In this embodiment, the power supply apparatus needs to support a handshake signal communication mechanism, and the power supply apparatus needs to transmit a handshake signal carrying the maximum power supply information each time the power supply apparatus starts to supply power to the power receiving apparatus.
Illustratively, the handshake signals comprise: the starting signal, the output voltage value, the maximum output current value and the power supply starting signal. When a certain power supply path starts to supply power to the powered device, it outputs a handshake signal in the form of a voltage square wave. The power supply apparatus immediately starts power supply output regardless of whether the power receiving apparatus responds to the handshake signal.
In the above embodiment, further, after the step S11, the method further includes:
s12, sending an inquiry signal to the power supply device at regular time, so that the power supply device returns a corresponding handshake signal to the power receiving device when determining that the power supply state of the power supply device changes according to the inquiry signal; the handshake signal includes maximum power supply information corresponding to a current power supply state of the power supply device.
