Based on the above, the present application provides a power supply method, a power supply device, and a storage medium, which can supply power to an exchange under the condition of abnormal power loss of the exchange, thereby maintaining normal operation of the exchange and a network device.
Example one
Referring to fig. 1, a first embodiment provides a power supply method, which includes the following steps:
and S11, acquiring external power supply information.
The power supply method of the embodiment one is applied to a power supply device, the power supply device includes a network device, and the network device is connected with a switch, and can be directly connected through a network port, and can also be connected with the switch through adapters of different types of ports.
The external power supply information includes whether the network device is connected to an external power supply on the exchange side. The network device can be a network camera, a video monitor, a network telephone, an industrial sensor and the like, and can also be other terminal devices which are networked through a switch network.
In step S11, the external power supply information may be acquired through an access port of the network device. For example, an access port of a network device includes a USB3.0 or USB type a/type b/type c port, and whether to access an external power source can be determined by detecting a voltage or a current of a port pin.
And S12, carrying out forward power supply by adopting an external power supply or carrying out reverse power supply by adopting an internal power supply according to external power supply information.
In step S12, the network device may determine whether to access the external power source by detecting the voltage amplitude or the current input of the access port. The external power supply can be a power supply of the switch or an independent standby power supply. If the external power supply is the power supply of the switch, the current flows from the switch to the network equipment, and the network equipment and the switch can be powered. If the external power supply is an independent standby power supply, the standby power supply can only supply power for the network equipment, and can also supply power for the network equipment and the switch at the same time.
The external Power source may be Power Over Ethernet (POE), or may be an Adapter (Adapter).
The internal power supply can be a power supply of the network equipment, and can also be an independent standby power supply. If the internal power supply is the power supply of the network equipment, the current flows from the network equipment to the switch, and the switch can be reversely powered. If the internal power supply is an independent standby power supply, the standby power supply can only supply power for the switch, and can also supply power for the network equipment and the switch at the same time. The internal power source may be powered by a Battery (Battery).
In the power supply method of the first embodiment, the external power supply is used for forward power supply or the internal power supply is used for reverse power supply, and an alternative power supply scheme can be provided when a power supply fault occurs to the switch or the network device, so that normal operation of the switch and the network device is guaranteed, network faults are reduced, and network stability is improved.
In some embodiments, step S11 specifically includes the following step S111: and detecting whether an external power supply is connected.
In step S111, whether an external power source is connected can be determined by detecting a voltage amplitude or a current input of the network device access port. When the network equipment adopts an internal power supply to supply power, the access port has no load, the voltage amplitude is 0, and no current is input; when the network equipment adopts an external power supply to supply power, the access port is hung with a load, the voltage amplitude is not 0, and current input exists. Whether the external power supply is connected or not is detected, judgment basis can be provided for power switching, and therefore a more flexible standby power supply scheme is provided.
In some embodiments, if the network device is connected to the external power source, step S12 includes the following specific steps:
s1211, disconnecting the power supply loop of the internal power supply.
In step S1211, the connection/disconnection of the internal power source may be controlled by the switch. The switch is connected between the access port of the network equipment and the power supply loop of the internal power supply.
The switch comprises a switch circuit which can be a triode switch circuit or a field effect transistor switch circuit and controls the connection on-off of the power supply loop through the high and low of the logic level. The logic level may be set according to the supply voltages of the external power supply and the internal power supply. The power supply voltage of the internal power supply can be set as a reference voltage, and if the power supply voltage of the external power supply is smaller than the reference voltage, the switch circuit is connected; and if the power supply voltage of the external power supply is not less than the reference voltage, the switching circuit is disconnected.
And S1212, adopting an external power supply to perform positive power supply.
In step S1212, the external power supply is connected to the network device through the access port, the voltage amplitude of the access port is transited, the power supply loop of the internal power supply is disconnected, at this time, the network device is powered by the external power supply, and the current is input from the access port. The external power supply can be used as an alternative power supply scheme of the network equipment, and when the network equipment has a power supply fault, the internal power supply can be switched into the external power supply, so that the normal work of the network equipment is maintained. In some embodiments, the external power source may serve as a main power supply of the network device, that is, the internal power source serves as a backup power supply of the network device, and when the network device is in normal operation, the access port is connected to the external power source, and the external power source continuously supplies power to the network device in a forward direction. When the external power supply has power supply failure, the internal power supply is switched to supply power, so that the normal work of the network equipment is guaranteed.
It is to be understood that the present embodiment does not limit the execution sequence of step S1211 and step S1212. In other embodiments, step S1211 may be performed after step S1212 is performed.
In some embodiments, if the network device does not access the external power source, step S12 includes the following specific steps S1221: and an internal power supply is adopted for reverse power supply.
In step S1221, if it is detected that the access port is not connected to the external power supply, the power supply circuit of the internal power supply is connected to supply power to the switch in the reverse direction.
It can be understood that the network device is connected with the switch, when there is no external power supply, it can be considered that the switch side has a power supply failure, and in order to avoid the network device from being disconnected, the internal power supply of the network device supplies power to the switch in a reverse direction, so as to maintain the normal operation of the network device and the switch.
In some embodiments, the external power source includes a first external power source and a second external power source, and if the first external power source and/or the second external power source is connected, the step S12 includes the following specific steps:
s1231, disconnecting a power supply loop of the internal power supply.
In step S1231, the network device includes at least two access ports, and the network device is connected to at least two corresponding external power sources through the at least two access ports. Taking two external power supplies as an example, the first access port is connected with the first external power supply, and the second access port is connected with the second access power supply. When an external power supply is connected, the voltage of the access port jumps, and the power supply loop of the internal power supply is disconnected.
It is understood that the first external power source and the second external power source may be powered by the same or different power modes, and the power modes include POE power supply or adapter power supply.
S1232, positive power supply is carried out by adopting the first external power supply or the second external power supply.
In step S1232, when two external power sources are simultaneously connected to the network device, only one of the external power sources is allowed to supply power to the network device to ensure power supply safety. A switch can be arranged between each access port and the internal power supply, and a multi-way selection switch can also be arranged between the access ports and the internal power supply. The priority of the external power supply can be set, and the corresponding switch link is selected to be conducted according to different priorities of the external power supply. The priority of the external power source may be set according to the magnitude of the supply voltage value. For example, the higher the supply voltage value of the external power supply, the higher the corresponding priority. When the external power supplies with different priorities are connected at the same time, the external power supply with low priority is disconnected, and only the external power supply with high priority is adopted for supplying power. When the external power supplies with the same priority are connected at the same time, one external power supply is randomly selected to be connected, the connection of other external power supplies is disconnected, and only one external power supply is reserved for supplying power.
It is to be understood that the present embodiment does not limit the execution sequence of step S1231 to step S1232. In other embodiments, step S1231 may be performed after step S1232 is performed.

s23, disconnecting a power supply loop of the internal power supply, and carrying out forward power supply by adopting an external power supply;
and S24, carrying out reverse power supply by adopting an internal power supply.
The present embodiment uses the internal power supply as the main power supply, that is, the internal power supply provides the power supply voltage of the network device in the normal operating state. When a power supply fault occurs on the side of the switch, the internal power supply supplies power to the switch in a reverse direction, and a Boost circuit such as a Boost chopper (Boost circuit) is arranged between the internal power supply and a connection port of the switch. The supply voltage of the internal power supply is converted into the operating voltage of the switch by the booster circuit.
