Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, 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.
Embodiments of the present invention provide a method, an apparatus, a system, a device, and a medium for identifying a fault of a powered device.
Example 1:
fig. 1 is a process schematic diagram of a method for identifying a fault of a powered device according to an embodiment of the present invention, where the process includes the following steps:
s101: and judging whether the power supply state of the port is a normal power supply state or not according to the state identification information of the port for supplying power to the power receiving equipment by the power supply equipment.
The fault identification method of the powered device provided by the embodiment of the invention is applied to the PSE for supplying power to the powered device.
In order to identify a failure in the powered device, in an embodiment of the present invention, when the electronic device is a power supply device, the power supply device does not supply power to the powered device because the powered device may be an illegal powered device or the powered device is not correctly connected to a port, and the like, and therefore, to identify the failure of the powered device, the power supply device first determines a power supply state of the port that supplies power to the powered device.
After the power supply device supplies power to the powered device, state identification information of a port for supplying power to the powered device is determined, wherein a method for determining, by the power supply device, the state identification information of the port for supplying power to the powered device according to an actual power supply situation belongs to the prior art, and details are not repeated in the embodiment of the present invention.
According to the state identification information of the port, where the power supply device supplies power to the power receiving device, whether the power supply state of the port is a normal power supply state is determined, where the state identification information of the port may be digital information or alphabetic information. The state identification information includes normal state identification information and abnormal state identification information. For example, the normal state identification information may be 1, and the abnormal state identification information may be 0; and if the state identification information is the normal state identification information, determining that the power supply state of the port is the normal power supply state.
S102: if yes, when it is monitored that the video code stream is not received through the port, the duration of the video code stream which is not received through the port is determined.
If the power supply state of the port is determined to be a normal power supply state, the port for supplying power to the power receiving equipment is monitored because the video code stream transmitted to the power supply equipment by the power receiving equipment is stopped when the power receiving equipment has a fault.
When it is monitored that the video code stream is not received through the port, since the video code stream sent by the powered device to the power supply device is interrupted for a period of time under certain conditions, in order to determine whether the video code stream is interrupted or stopped, the duration of the video code stream which is not received through the port is also determined.
S103: and if the duration exceeds a first preset duration threshold, determining that the powered device corresponding to the port has a fault.
When the duration of the video code stream which is not received through the port is determined to exceed a first preset duration threshold, the video code stream which is sent to the power supply equipment by the power receiving equipment corresponding to the port is determined to stop, and therefore the power receiving equipment corresponding to the port is determined to have a fault. The first preset duration threshold is preset, and the size of the first preset duration threshold is greater than the maximum duration of possible interruption of the video code stream, for example, the first preset duration threshold may be 3 minutes, 4 minutes, 5 minutes, or the like.
When the duration of not receiving the video code stream is determined not to exceed the first preset duration threshold, it is determined that the video code stream sent by the power receiving equipment to the power supply equipment is interrupted, and therefore it is determined that the fault of the power receiving equipment does not exist in the power receiving equipment corresponding to the port.
S104: and if the power supply state of the port is a non-power supply state, determining that the power receiving equipment corresponding to the port has a fault.
And if the state identification information is abnormal state identification information, determining that the power supply state of the port is a non-power supply state, and determining that the power supply equipment does not supply power to the power receiving equipment and the power receiving equipment corresponding to the port has a fault.
When the power supply state of the port is determined to be a non-power supply state, a fault that the powered device corresponding to the port has may be a fault that the powered device is an illegal powered device, may be a fault that the powered device is incorrectly connected to the port, may be a fault that the powered device itself is stuck, and the like, which needs to be manually processed.
According to the embodiment of the invention, whether the fault of the powered device exists in the powered device corresponding to the port is judged according to the duration of the video code stream which is not received through the port aiming at the state of the port for supplying power to the powered device, so that the fault of power consumption change of any size in the powered device is identified.
Example 2:
to solve the failure of the powered device, in an embodiment of the present invention, on the basis of the above-described embodiment, the method further includes:
controlling the port to interrupt power supply to the powered device, and restarting the powered device;
judging whether the restarting frequency of the power receiving equipment reaches a set frequency threshold value or not;
and if so, controlling the port to be closed and stopping supplying power to the power receiving equipment.
In order to solve the failure of the powered device, in the embodiment of the present invention, after the electronic device determines that the powered device corresponding to the port has a failure, the electronic device controls the port to interrupt power supply to the powered device, so that the powered device is restarted.
After the powered device is restarted, since the fault of the powered device may still exist and may also be resolved, in order to determine whether the fault of the powered device still exists, the step of identifying the fault of the powered device may also be performed again.
And after determining that the fault still exists in the powered device, in order to solve the fault of the powered device, the port is still controlled to interrupt power supply to the powered device, so that the powered device is restarted. In order to ensure the safety of the power receiving apparatus, the power receiving apparatus cannot be restarted many times in a short time, and therefore a set number threshold is also stored in advance.
Judging whether the restarting frequency of the powered device in a set time length reaches a set frequency threshold value, if the restarting frequency reaches the set frequency threshold value, determining that the powered device corresponding to the port has a fault needing manual processing, controlling the port to close and stopping supplying power to the powered device in order to ensure the safety of the powered device, and if the restarting frequency does not reach the set frequency threshold value, executing a step of identifying the fault of the powered device.
Example 3:
in order to accurately identify a fault of a powered device, on the basis of the foregoing embodiments, in an embodiment of the present invention, after determining that a power supply state of the port is a normal power supply state, before monitoring that a video stream is not received through the port, the method further includes:
and monitoring the port after delaying a second preset time threshold, wherein the second preset time threshold is smaller than the first preset time threshold.
In order to accurately identify the fault of the powered device, in the embodiment of the present invention, since a certain time interval exists between the time when the power supply device supplies power to the powered device and the time when the powered device sends a video code stream to the power supply device, after the power supply state of the port is determined to be the normal power supply state, the port may be monitored after a second preset time threshold is delayed.
The second preset time threshold is smaller than the first preset time threshold, preferably, the first preset time threshold is 3 minutes, and the second threshold is 1 minute.
