Referring to fig. 1, a processing circuit for multiple power supply ports includes: the system comprises N control modules 12 and a bus 13, wherein each control module 12 is used for being correspondingly connected with one power supply port 11, N is an integer greater than or equal to 2, and a communication interface 121 of each control module 12 is connected to the bus 13; the bus 13 is connected with a power ground through a bus resistor R, and the bus is a single-wire bus.
The power supply port 11 may be any port, and as long as the power supply port can output a certain power to the outside, the power supply port does not depart from the description of the embodiment, regardless of whether the power supply port is used for meeting the power consumption requirement or the charging requirement of the external device. In one embodiment, the power supply port may be a USB port, specifically may adopt Type-C, may also adopt Type-a, and may also adopt Type-B standard, and meanwhile, in other embodiments, ports adopting other structures such as lightning ports are not excluded.
The connection between the control module 12 and the power supply port 11 may be a direct connection or an indirect connection, which may be understood as: any direct and indirect connection mode that the power supply information of the power supply port is known by the corresponding control module does not depart from the description of the embodiment, for example: the power supply information of the power supply port may be determined under the control of the control module, which is naturally able to learn its power supply information, again for example: the power supply information of the power supply port can be detected by the control module through the related circuit.
In the present embodiment, the communication interface 121 of each control module 12 is connected to the bus 13; the bus 13 is connected with a power ground through a bus resistor R, and the bus 13 is a single-wire bus. The bus 13 may also be connected to a bus power supply either directly or via another bus resistor.
The single-wire bus is understood to have a current flowing path along a single direction, and specifically may flow from a terminal far away from a power ground (e.g., from a ground power supply) to the power supply. Furthermore, as long as the description is satisfied, the wiring, the forming method, the size and the number of the metal wires are not deviated from the description of the embodiment, regardless of the formed wiring.
Because it is a single-wire bus, compared with a bidirectional communication bus, the use of a single-wire bus can have a lower cost, and meanwhile, the control module 12 and the corresponding processing process are configured based on the single-wire bus, so that the control module 12 can learn the power supply information of other control modules 12. Meanwhile, the numerical value signal of any control module can act on the single-wire bus, so that other modules can accurately learn.
In this embodiment, the control module 12 can send a numerical signal to the bus 13 through the communication interface 121, so as to enable a first physical quantity of the bus signal to change accordingly, where a change amplitude of the first physical quantity of the bus signal is associated with a first physical quantity or a second physical quantity of all target signals sent to the bus.
The control module 12 is further capable of detecting a first physical quantity of a bus signal on the bus 13 through the communication interface 121, and adjusting an operating parameter of the connected power supply port according to a variation range of the detected first physical quantity.
The value signal can be understood as a value for representing the current power supply information of the power supply port connected with the corresponding control module, and can satisfy the following conditions: through the output of the value signal, a corresponding change of the first physical quantity can be caused, thereby facilitating the identification of the power supply information or other information associated therewith.
The current power supply information may be understood as any one of the operating parameters, such as power, voltage, current, and temperature, for characterizing the power supply port connected to the current master module, and the value represented by the value signal may be a corresponding power value, voltage value, current value, and temperature value. Meanwhile, the embodiment does not exclude the implementation of other working parameters and corresponding numerical values.
In the above scheme, each control module is connected with the same single-wire bus through the communication port, and the bus signal on the bus can be influenced by the numerical signal sent by the main module to change, the bus signal can reflect the power supply information represented by the numerical signal to a certain extent, and further, each control module can conveniently learn the power supply information of the power supply ports controlled by other modules through detecting the first physical quantity in the bus signal, the power supply information does not need to be reported to the central controller for uniform processing, and further, a central processor does not need to be configured, and therefore, a bus for bidirectional communication does not need to be configured, and the cost is effectively reduced.
In addition, if N is 2, part of the existing solutions may also directly utilize the two control modules to connect with the two control modules through the bidirectional communication line, so as to obtain the power supply information through mutual communication, however, the solutions cannot support the scenario of three and three power supply ports. Meanwhile, the cost can be reduced because the bidirectional communication line does not need to be configured.
In one embodiment, when the control module adjusts the working parameter of the connected power supply port according to the detected variation amplitude of the first physical quantity, the control module is specifically configured to:
according to the first physical quantity of the bus signal, determining the sum of second physical quantities of signals sent to the bus by other control modules connected to the bus so as to represent the sum of current power supply information of other control modules by using the sum;
and adjusting the working parameters of the connected power supply port according to the sum of the current power supply information of other control modules.
The first physical quantity may be a voltage and the second physical quantity may be a current. In other alternative embodiments, the second physical quantity may also be a voltage, a power, etc., and the first physical quantity may also be a power.
The sum of the current power supply information and the adjusted operating parameter may be the same type of parameter, for example, the power of the connected power supply port may be adjusted according to the sum of the powers of other control modules, in other examples, the two may also be different, for example, the voltage and the current of the connected power supply port may also be adjusted according to the sum of the powers of other control modules, or the power of the connected power supply port may also be adjusted according to the sum of the temperatures of other control modules.
Taking the first physical quantity as a voltage and the second physical quantity as a current as an example, if each control module is arranged on one chip, then:
I(total)＝I(1)+…I(n)…+I(N)＝V÷R；
wherein:
i (n) represents the current output to the bus by the nth control module, i.e. the second physical quantity output to the bus by the nth control module;
i (total) represents the sum of currents output to the bus by all the modules, namely the sum of second physical quantities of signals output by all the control modules;
v represents a currently measured voltage of the bus signal, i.e., a first physical quantity of the bus signal;
r represents the resistance value of the bus resistor;
since the current applied to the bus resistor is the sum of the output currents of all the control modules, i (total) can be obtained by using the above formula.
Furthermore, for any kth control module, the total second physical quantity of the other related control modules is: i (others) ═ i (total) -i (k).
In a specific implementation process, according to the sum of the current power supply information of other control modules, the working parameters of the connected power supply port are adjusted, for example: if the sum of the current power supply information is the sum of the powers, the power of the connected power supply port can be adjusted according to the sum of the powers, for example: the power of the power supply port and the power of other power supply ports can be added to reach the maximum power, or the sum of the power supply port and the power of other power supply ports is smaller than a safety power threshold value, and the like.
I (others) may be used to characterize the sum of the current power supply information of the other control modules, which may then be converted into a specific value of the sum of the power supply information. In other scenarios, only i (total) or the converted specific value thereof may be used without stripping i (k), statistical information such as a mean value may be calculated based on i (others), i (total) or the converted specific value thereof, and other processing requirements may be satisfied by comparing i (others), i (total) or the converted specific value thereof in different periods.
As can be seen, based on the processing requirements in various scenarios, any other calculation and processing may be optionally performed based on the obtained i (total), without departing from the description of the present embodiment.
