With continued reference to FIG. 2, a flow 200 of one embodiment of a method for outputting information in accordance with the present application is shown. The method for outputting information comprises the following steps:

step 201, determining whether the electric equipment connected with the target connector is in a first state.

In this embodiment, an execution subject (for example, a server shown in fig. 1) of the method for outputting information may determine whether the electric device to which the target connector is connected is in the first state by a wired connection manner or a wireless connection manner. The target connector may be a connector whose connection state is to be detected. The target connector may be for connecting the first power supply device and the powered device. The electric equipment can be powered by two power supply equipment (a first power supply equipment and a second power supply equipment). Specifically, the first state of the electric equipment is that power is supplied by the first power supply equipment and the second power supply equipment. Here, the execution main body may be communicatively connected to two power supply lines of the electric device, and the execution main body may determine whether the electric device to which the target connector is connected is in the first state by determining on/off of the two power supply lines. It should be noted that the two power supply lines include a power supply line where the first power supply device is located and a power supply line where the second power supply device is located.

For example, fig. 3 is a schematic view of a monitoring system provided in an embodiment of the present application. The target connector 301 is used to connect the first power supply device 302 and the electric device 303. The connector 304 may be used to connect the second power supply device 305 and the powered device 303. The power meter 306 may be used to detect a preceding stage voltage of the target connector 301 and transmit the detected preceding stage voltage to the execution main body (server) 307. The power meter 308 may be used to detect the rear-stage voltage of the target connector 301 and transmit the detected rear-stage voltage to the execution main 307. The execution main body 307 may be communicatively connected to a power supply line on which the first power supply apparatus 302 is located and a power supply line on which the second power supply apparatus 305 is located.

Step 202, in response to determining that the powered device is in the first state, performing the following steps: acquiring a first front-stage voltage and a first rear-stage voltage of a target connector; converting a first state of the electric equipment into a second state; acquiring a second front-stage voltage and a second rear-stage voltage of the target connector; generating a characteristic value for characterizing the connection characteristic of the target connector based on the acquired first preceding stage voltage, first succeeding stage voltage, second preceding stage voltage and second succeeding stage voltage; and outputting preset alarm information in response to determining that the generated characteristic value is larger than a preset threshold value.

In this embodiment, the executing body may execute the following steps in response to determining that the electric device is in the first state:

step 2021, obtain the first front stage voltage and the first back stage voltage of the target connector.

In this embodiment, the execution body may obtain a first front stage voltage and a first rear stage voltage of the target connector. The front-stage voltage is the voltage when the voltage provided by the power supply equipment is not dropped by the connector, and the rear-stage voltage is the voltage when the voltage provided by the power supply equipment is dropped by the connector. Specifically, the executing body may acquire a first former-stage voltage and a first latter-stage voltage of the target connector detected by the detecting device (e.g., the detecting device 101 shown in fig. 1). Here, the first preceding-stage voltage and the first succeeding-stage voltage correspond to the first state described above.

Step 2022, convert the first state of the powered device to a second state.

In this embodiment, the execution body may convert the first state of the electric device into the second state. And the second state of the electric equipment is that power is supplied by the second power supply equipment. Specifically, the execution main body may be communicatively connected to two power supply lines of the electric device. Furthermore, the execution main body can control the power supply state of the electric equipment by controlling the on-off of the two power supply lines. It is understood that, here, the execution main body may control the power supply line where the first power supply device is located to be disconnected to convert the first state of the electric device into the second state.

Step 2023, obtain the second front stage voltage and the second back stage voltage of the target connector.

In this embodiment, the execution body may obtain a second front stage voltage and a second rear stage voltage of the target connector. Here, the second preceding-stage voltage and the second succeeding-stage voltage correspond to the above-described second state. Specifically, the executing body may acquire the second front-stage voltage and the second rear-stage voltage of the target connector detected by the detecting device (e.g., the detecting device 101 shown in fig. 1).

Step 2024, based on the acquired first previous-stage voltage, first subsequent-stage voltage, second previous-stage voltage, and second subsequent-stage voltage, generates a characteristic value for characterizing the connection characteristic of the target connector.

In this embodiment, the execution body described above may generate a characteristic value for characterizing the connection characteristic of the target connector based on the acquired first preceding-stage voltage, first succeeding-stage voltage, second preceding-stage voltage, and second succeeding-stage voltage. Wherein the connection characteristic may be used to characterize a connection state of the target connector. The connection state of the target connector may include normal connection, virtual connection, and the like. Specifically, the connection characteristics of the target connector may be resistance, power consumed, voltage occupied, and the like of the target connector during use. Accordingly, the characteristic value may be a resistance value, a power value, a voltage value, or the like.

In some optional implementations of the embodiment, based on the acquired first previous-stage voltage, first subsequent-stage voltage, second previous-stage voltage, and second subsequent-stage voltage, the execution body may generate a characteristic value for characterizing a connection characteristic of the target connector by:

first, the execution main body may perform difference processing on the acquired first previous-stage voltage and first subsequent-stage voltage to obtain a first voltage difference value.

Then, the executing body may perform a difference processing on the acquired second previous-stage voltage and second subsequent-stage voltage to obtain a second voltage difference value.

Then, the executing body may perform a difference processing on the first voltage difference value and the second voltage difference value to obtain a voltage drop value generated by the target connector.

Finally, the execution body may generate a characteristic value for characterizing a connection characteristic of the target connector based on the obtained voltage drop value.

As an example, the execution body may first acquire a first former voltage "5V", a first latter voltage "4V", a second former voltage "4.7V", and a second latter voltage "3.9V" of the target connector. The execution body may then perform a difference process on the acquired first previous-stage voltage "5V" and first subsequent-stage voltage "4V" to obtain a first voltage difference value "1" (1 ═ 5-4). Then, the execution body may perform a difference process on the acquired second previous-stage voltage "4.7V" and second subsequent-stage voltage "3.9V" to obtain a second voltage difference value "0.8" (0.8 — 4.7-3.9). Next, the executing body may perform a difference processing on the first voltage difference value "1" and the second voltage difference value "0.8" to obtain a voltage drop value "0.2" (0.2 — 0.8) generated by the target connector. Finally, the execution body described above may generate a characteristic value for characterizing the connection characteristic of the target connector based on the obtained voltage drop value "0.2". For example, the execution body described above may determine the obtained voltage drop value "0.2" as a characteristic value for characterizing the connection characteristic of the target connector.

Step 2025, in response to determining that the generated characteristic value is greater than the preset threshold, outputting preset alarm information.

In this embodiment, the execution subject described above may output warning information set in advance in response to a determination that the generated characteristic value is greater than a preset threshold value. The preset threshold may be a numerical value preset by a technician for detecting the connection state of the target connector based on the attribute and performance of the target connector. The connection characteristic of the target connector corresponding to the preset threshold is the same as the connection characteristic of the target connector corresponding to the characteristic value.

For example, the execution body may determine the voltage difference value as a characteristic value for characterizing the connection characteristic of the target connector. The preset threshold may be a voltage threshold occupied by the target connector. Further, the execution body may determine whether the generated feature value is greater than a preset threshold.

In this embodiment, the alarm information may include, but is not limited to, at least one of: text, symbols, images, video, audio. The alarm information may be information preset by a technician for monitoring the connection state of the target connector.

It should be noted that, in general, for a connector used for connecting a power supply device and a power consumption device, when a virtual connection occurs during use, the resistance value of the connector will increase. The execution body may determine the connection state of the target connector based on the generated characteristic value according to the property of the connector.

With continued reference to fig. 4, fig. 4 is a schematic diagram of an application scenario of the method for outputting information according to the present embodiment. In the application scenario of fig. 4, the server 401 may first determine whether the electrical device connected to the target connector is in a first state, where the target connector is used to connect the first power supply device and the electrical device, and the first state of the electrical device is to supply power through the first power supply device and the second power supply device; next, the server 401 may perform the following steps in response to determining that the powered device is in the first state: acquiring a first front-stage voltage ("5V") 403 of the target connector sent by the detection device 402 and a first rear-stage voltage ("4V") 405 of the target connector sent by the detection device 404, wherein the front-stage voltage is a voltage when the voltage provided by the power supply device is not dropped by the connector, and the rear-stage voltage is a voltage when the voltage provided by the power supply device is dropped by the connector; next, the server 401 may convert the first state of the electrical device into a second state, where the second state of the electrical device is a state in which power is supplied by a second power supply device; then, the server 401 acquires a second former-stage voltage ("4.7V") 406 of the target connector transmitted by the detection device 402 and a second latter-stage voltage ("3.9V") 407 of the target connector transmitted by the detection device 404; next, the server 401 may generate a characteristic value ("0.2") 408 for characterizing the connection characteristic of the target connector based on the acquired first preceding-stage voltage 403, first succeeding-stage voltage 405, second preceding-stage voltage 406, and second succeeding-stage voltage 407; finally, the server 401 may output the preset alert information ("!!!!") 409 in response to determining that the generated characteristic value ("0.2") is greater than the preset threshold value ("0.1").

The method provided by the above embodiment of the present application is implemented by determining whether a powered device connected to a target connector is in a first state; in response to determining that the powered device is in the first state, performing the steps of: acquiring a first front-stage voltage and a first rear-stage voltage of a target connector; converting a first state of the electric equipment into a second state; acquiring a second front-stage voltage and a second rear-stage voltage of the target connector; generating a characteristic value for characterizing the connection characteristic of the target connector based on the acquired first preceding stage voltage, first succeeding stage voltage, second preceding stage voltage and second succeeding stage voltage; and outputting preset alarm information in response to the fact that the generated characteristic value is larger than the preset threshold value, so that the connection state of the connector is monitored by effectively utilizing data such as the preceding-stage voltage and the subsequent-stage voltage in the two power supply processes, the virtual connection state of the connector is alarmed, meanwhile, the influence of errors of detection equipment can be reduced by determining the characteristic value through the two states of the electric equipment, and the accuracy of information output is improved.

With further reference to fig. 5, a flow 500 of yet another embodiment of a method for outputting information is shown. The process 500 of the method for outputting information includes the following steps:

step 501, determining whether the electric equipment connected with the target connector is in a first state.

Step 502, in response to determining that the powered device is in the first state, performing the following steps: acquiring a first front-stage voltage and a first rear-stage voltage of a target connector and a current value of a circuit where the target connector is located; converting a first state of the electric equipment into a second state; acquiring a second front-stage voltage and a second rear-stage voltage of the target connector; performing difference processing on the acquired first front-stage voltage and the acquired first rear-stage voltage to acquire a first voltage difference value; performing difference processing on the obtained second front-stage voltage and second rear-stage voltage to obtain a second voltage difference value; performing difference processing on the first voltage difference value and the second voltage difference value to obtain a voltage drop value generated by the target connector; based on the obtained voltage drop value, a characteristic value for characterizing the connection characteristic of the target connector is generated. Generating a characteristic value for characterizing the connection characteristic of the target connector based on the obtained voltage drop value and current value; and outputting preset alarm information in response to determining that the generated characteristic value is larger than a preset threshold value.

step 5021, obtaining a first front-stage voltage and a first rear-stage voltage of the target connector and a current value of a circuit where the target connector is located.

In this embodiment, the executing body may obtain a first front-stage voltage and a first rear-stage voltage of the target connector, and a current value of a circuit in which the target connector is located. The front-stage voltage is the voltage when the voltage provided by the power supply equipment is not dropped by the connector, and the rear-stage voltage is the voltage when the voltage provided by the power supply equipment is dropped by the connector. Specifically, the executing body may obtain a first previous-stage voltage, a first subsequent-stage voltage, and a current value of a circuit in which the target connector is located, of the target connector detected by a detection device (for example, the detection device 101 shown in fig. 1). Here, the first preceding stage voltage, the first succeeding stage voltage, and the current value correspond to the first state.

Step 5022, the first state of the electric equipment is converted into a second state.

Step 5023, a second front-stage voltage and a second rear-stage voltage of the target connector are obtained.

In this embodiment, the execution body may obtain a second front stage voltage and a second rear stage voltage of the target connector. Specifically, the executing body may acquire the second front-stage voltage and the second rear-stage voltage of the target connector detected by the detecting device (e.g., the detecting device 101 shown in fig. 1). Here, the second preceding-stage voltage and the second succeeding-stage voltage correspond to the second state.

Step 5024, difference processing is conducted on the acquired first front-stage voltage and the acquired first rear-stage voltage, and a first voltage difference value is obtained.

In this embodiment, a difference processing is performed on the acquired first previous-stage voltage and first subsequent-stage voltage to obtain a first voltage difference value. Note that when a voltage is detected by a detection device (e.g., a power meter), the detection device itself tends to generate an error. Here, in order to output more accurate information, the sum of the first voltage difference value and the error of the detection device may be determined as a voltage drop value generated by the target connector for the first state in consideration of the error of the detection device.

Step 5025, difference processing is carried out on the obtained second front-stage voltage and the second rear-stage voltage, and a second voltage difference value is obtained.

In this embodiment, a difference between the acquired second previous-stage voltage and the acquired second subsequent-stage voltage is obtained to obtain a second voltage difference. Here, the sum of the second voltage difference value and the error of the detection device may be determined as a voltage drop value generated by the target connector for the second state. It is understood that, since the power supply line on which the first power supply device is located is disconnected when the electric device is in the above-described second state, the voltage drop value generated by the target connector is "0". Further, it can be determined that the error of the detection device is the inverse of the second voltage difference.

Step 5026, difference processing is conducted on the first voltage difference value and the second voltage difference value, and a voltage drop value generated by the target connector is obtained.

In this embodiment, the executing entity may perform a difference processing on the first voltage difference value and the second voltage difference value to obtain a voltage drop value generated by the target connector. The voltage drop value generated by the target connector is the voltage drop value generated by the target connector for the first state. It can be understood that, here, since the error of the detection device is the opposite number of the second voltage difference, the difference processing of the first voltage difference and the second voltage difference is equivalent to the summation processing of the first voltage difference and the error of the detection device, and thus the differential voltage drop value of the target connector can be obtained.

Step 5027, based on the obtained voltage drop value and the current value, a characteristic value for characterizing the connection characteristic of the target connector is generated.

In the present embodiment, the execution body described above may generate a characteristic value for characterizing the connection characteristic of the target connector based on the obtained voltage drop value and current value. Wherein the connection characteristic may be used to characterize a connection state of the target connector. The connection state of the target connector may include normal connection, virtual connection, and the like. Specifically, the connection characteristics of the target connector may be resistance, power consumed, voltage occupied, and the like of the target connector during use. Accordingly, the characteristic value may be a resistance value, a power value, a voltage value, or the like.

In some optional implementations of the present embodiment, based on the obtained voltage drop value and current value, the executing body may generate a characteristic value for characterizing a connection characteristic of the target connector by:

first, the execution body may perform quotient processing on the voltage drop value and the current value to obtain the resistance value of the target connector.

Then, the execution body described above may determine the obtained resistance value as a characteristic value for characterizing the connection characteristic of the target connector.

Optionally, the executing body may further obtain a power value of power consumed by the target connector based on performing an integral process on the voltage drop value and the current value, and further determine the obtained power value as a characteristic value for characterizing connection characteristics of the target connector.

Step 5028, responding to the fact that the generated characteristic value is larger than a preset threshold value, and outputting preset alarm information.

As can be seen from fig. 5, compared with the embodiment corresponding to fig. 2, the flow 500 of the method for outputting information in the present embodiment highlights that the current value of the circuit where the target connector is located in the first state is obtained, and then the characteristic value for characterizing the connection characteristic of the target connector is determined by the current value and the voltage drop value generated by the target connector. Therefore, the scheme described by the embodiment can introduce more data related to the connection characteristics of the target connector, thereby realizing more accurate information output.

As an implementation of the method shown in the above figures, the present application provides an embodiment of an apparatus for outputting information, which corresponds to the method embodiment shown in fig. 2, and which is particularly applicable to various electronic devices.

The apparatus for outputting information of the present embodiment includes: a determination unit and an execution unit. The determining unit is configured to determine whether an electrical device connected to a target connector is in a first state, wherein the target connector is used for connecting a first power supply device and the electrical device, and the first state of the electrical device is that power is supplied through the first power supply device and a second power supply device; the execution unit is configured to, in response to determining that the powered device is in the first state, perform the following steps: acquiring a first front-stage voltage and a first rear-stage voltage of a target connector, wherein the front-stage voltage is the voltage provided by power supply equipment when the voltage is not dropped by the connector, and the rear-stage voltage is the voltage provided by the power supply equipment after the voltage is dropped by the connector; converting the first state of the electric equipment into a second state, wherein the second state of the electric equipment is that power is supplied through second power supply equipment; acquiring a second front-stage voltage and a second rear-stage voltage of the target connector; generating a characteristic value for characterizing the connection characteristic of the target connector based on the acquired first preceding stage voltage, first succeeding stage voltage, second preceding stage voltage and second succeeding stage voltage; and outputting preset alarm information in response to determining that the generated characteristic value is larger than a preset threshold value.

In this embodiment, the determination unit of the apparatus for outputting information may determine whether the electric device to which the target connector is connected is in the first state by a wired connection manner or a wireless connection manner. The target connector may be a connector whose connection state is to be detected. The target connector may be for connecting the first power supply device and the powered device. The electric equipment can be powered by two power supply equipment (a first power supply equipment and a second power supply equipment). Specifically, the first state of the electric equipment is that power is supplied by the first power supply equipment and the second power supply equipment. Here, the determination unit may be communicatively connected to two power supply lines of the above-mentioned electric device, and further, the determination unit may determine whether the electric device to which the target connector is connected is in the first state by determining on/off of the above-mentioned two power supply lines. It should be noted that the two power supply lines include a power supply line where the first power supply device is located and a power supply line where the second power supply device is located.

In this embodiment, the execution unit may perform, in response to determining that the powered device is in the first state, the following steps:

step 6021, acquiring a first front stage voltage and a first rear stage voltage of the target connector.

In this embodiment, the execution unit may obtain a first front stage voltage and a first rear stage voltage of the target connector. The front-stage voltage is the voltage when the voltage provided by the power supply equipment is not dropped by the connector, and the rear-stage voltage is the voltage when the voltage provided by the power supply equipment is dropped by the connector. Specifically, the execution unit may acquire a first former-stage voltage and a first latter-stage voltage of the target connector detected by the detection device (e.g., the detection device 101 shown in fig. 1). Here, the first preceding-stage voltage and the first succeeding-stage voltage correspond to the first state described above.

Step 6022, converting the first state of the powered device to a second state.

In this embodiment, the execution unit may convert the first state of the electric device into the second state. And the second state of the electric equipment is that power is supplied by the second power supply equipment. In particular, the execution unit may be communicatively connected to two power supply lines of the consumer. Furthermore, the execution unit can control the power supply state of the electric equipment by controlling the on-off of the two power supply lines. It is understood that, here, the execution unit may control the power supply line on which the first power supply device is located to be disconnected to convert the first state of the electric device into the second state.

Step 6023, acquiring a second front stage voltage and a second rear stage voltage of the target connector.

In this embodiment, the execution unit may obtain a second front stage voltage and a second rear stage voltage of the target connector. Here, the second preceding-stage voltage and the second succeeding-stage voltage correspond to the above-described second state. Specifically, the execution unit may acquire the second front-stage voltage and the second rear-stage voltage of the target connector detected by the detection device (e.g., the detection device 101 shown in fig. 1).

Step 6024 of generating a characteristic value for characterizing the connection characteristic of the target connector based on the acquired first preceding-stage voltage, first succeeding-stage voltage, second preceding-stage voltage, and second succeeding-stage voltage.

In this embodiment, the execution unit may generate a characteristic value for characterizing the connection characteristic of the target connector based on the acquired first preceding-stage voltage, first succeeding-stage voltage, second preceding-stage voltage, and second succeeding-stage voltage. Wherein the connection characteristic may be used to characterize a connection state of the target connector. The connection state of the target connector may include normal connection, virtual connection, and the like. Specifically, the connection characteristics of the target connector may be resistance, power consumed, voltage occupied, and the like of the target connector during use. Accordingly, the characteristic value may be a resistance value, a power value, a voltage value, or the like.

Step 6025, in response to determining that the generated characteristic value is greater than the preset threshold, outputting preset alarm information.

In this embodiment, the execution unit may output warning information set in advance in response to a determination that the generated characteristic value is greater than a preset threshold value. The preset threshold may be a numerical value preset by a technician for detecting the connection state of the target connector based on the attribute and performance of the target connector. The connection characteristic of the target connector corresponding to the preset threshold is the same as the connection characteristic of the target connector corresponding to the characteristic value.

It should be noted that, in general, for a connector used for connecting a power supply device and a power consumption device, when a virtual connection occurs during use, the resistance value of the connector will increase. The execution unit may determine the connection state of the target connector based on the generated characteristic value according to the above-described property of the connector.

In some optional implementations of this embodiment, the execution unit may be further configured to: performing difference processing on the acquired first front-stage voltage and the acquired first rear-stage voltage to acquire a first voltage difference value; performing difference processing on the obtained second front-stage voltage and second rear-stage voltage to obtain a second voltage difference value; performing difference processing on the first voltage difference value and the second voltage difference value to obtain a voltage drop value generated by the target connector; based on the obtained voltage drop value, a characteristic value for characterizing the connection characteristic of the target connector is generated.

In some optional implementations of this embodiment, the execution unit may be further configured to: acquiring a current value of a circuit where a target connector is located; based on the obtained voltage drop value and current value, a characteristic value for characterizing the connection characteristic of the target connector is generated.

In some optional implementations of this embodiment, the execution unit may be further configured to: carrying out quotient calculation on the voltage drop value and the current value to obtain the resistance value of the target connector; the obtained resistance value is determined as a characteristic value for characterizing the connection characteristic of the target connector.

The apparatus provided by the above embodiment of the present application determines, by the determination unit, whether the electric device to which the target connector is connected is in the first state; the execution unit, in response to determining that the powered device is in the first state, performs the steps of: acquiring a first front-stage voltage and a first rear-stage voltage of a target connector; converting a first state of the electric equipment into a second state; acquiring a second front-stage voltage and a second rear-stage voltage of the target connector; generating a characteristic value for characterizing the connection characteristic of the target connector based on the acquired first preceding stage voltage, first succeeding stage voltage, second preceding stage voltage and second succeeding stage voltage; and outputting preset alarm information in response to the fact that the generated characteristic value is larger than the preset threshold value, so that the connection state of the connector is monitored by effectively utilizing data such as the preceding-stage voltage and the subsequent-stage voltage in the two power supply processes, the virtual connection state of the connector is alarmed, meanwhile, the influence of errors of detection equipment can be reduced by determining the characteristic value through the two states of the electric equipment, and the accuracy of information output is improved.
