Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, of the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, a schematic diagram of a detection circuit provided by an embodiment of the present invention is shown 1. As shown in fig. 1, the detection circuit includes a connector 10 and an analog-to-digital conversion detection module 20.
The connector 10 has a first voltage pin 30 and a second pin 40 disposed adjacent to the first voltage pin 30, the second pin 40 is electrically connected to the analog-to-digital conversion detection module 20, and the analog-to-digital conversion detection module 20 is configured to detect a first voltage after the first voltage pin 30 and the second pin 40 are conducted. The analog-to-digital conversion detection module 20 outputs a first signal in case the first voltage is greater than or equal to the first threshold voltage.
It should be noted that, in the embodiment of the present invention, as shown in fig. 1, the connector may further have at least one signal pin 60, in this case, the first voltage pin 30, the second pin 40 and the signal pin 60 are disposed on the connector 10 at intervals, and the second pin 40 is located between the first voltage pin 30 and the signal pin 60 to separate the first voltage pin 30 from the signal pin 60.
In the embodiment of the present invention, the connector 10 has the first voltage pin 30 and the second pin 40 disposed adjacent to the first voltage pin 30, the second pin 40 is electrically connected to the analog-to-digital conversion detection module 20, the analog-to-digital conversion detection module 20 is used for detecting the first voltage after the first voltage pin 30 and the second pin 40 are conducted, and, under the condition that the first voltage is greater than or equal to the first threshold voltage, the analog-to-digital conversion detection module 20 outputs the first signal, therefore, when the first voltage pin 30 and the second pin 40 are conducted, that is, the first voltage pin 30 and the second pin 40 are short-circuited, at this time, the analog-to-digital conversion detection module 20 can detect the first voltage, and output the first signal under the condition that the first voltage is greater than or equal to the first threshold voltage.
That is, in the embodiment of the present invention, as long as the first voltage pin 30 and the second pin 40 are short-circuited, the analog-to-digital conversion detection module 20 can detect the first voltage without the first voltage pin 30 emitting enough heat, so that the detection of the connector 10 is more sensitive. Moreover, when the first voltage pin 30 and the second pin 40 are short-circuited, the first voltage may be detected by the analog-to-digital conversion detection module 20, and the first signal is sent when the first voltage is greater than or equal to the first threshold voltage, which may also play a role in preventing a short-circuit between the first voltage pin 30 and the signal pin 60 on the connector 10, and prevent the occurrence of a short-circuit between the first voltage pin 30 and the signal pin 60 due to undetected short-circuit between the first voltage pin 30 and the second pin 40, thereby improving the safety when the connector 10 is used.
In addition, theIn the embodiment of the present invention, referring to fig. 2, a schematic diagram of another detection circuit provided in the embodiment of the present invention is shown. As shown in fig. 1 and 2, the first voltage pin 30 may be VBUSThe pin can also be VBATAnd (7) a pin. The second pin 40 may be a null pin (NOT CONNECTED, NC). Of course, the first voltage pin 30 may also be other pins, and the embodiment of the present invention is not limited herein.
Additionally, in some embodiments, as shown in fig. 1, the analog-to-digital conversion detection module 20 may include a protection circuit 21 and an analog-to-digital converter 22. The first terminal of the protection circuit 21 is electrically connected to the second pin 40, the second terminal of the protection circuit 21 is grounded, and the analog-to-digital converter 22 is electrically connected between the first terminal and the second terminal of the protection circuit.
It should be noted that the protection circuit 21 is configured to share the voltage after the first voltage pin 30 and the second pin 40 are short-circuited, and the analog-to-digital converter 22 is configured to detect the voltage on the protection circuit 21.
When the first voltage pin 30 and the second pin 40 are conducted, i.e. the first voltage pin 30 and the second pin 40 are short-circuited, a voltage is generated on the second pin 40, and the adc 22 is connected to the protection circuit 21 in order to prevent the adc 22 from being damaged by an excessive voltage. Since the second pin 40 is connected to the protection circuit 21, when there is a voltage on the second pin 40, at this time, the protection circuit 21 can perform a voltage division function, so that the voltage on the analog-to-digital conversion detection module 20 is small, thereby preventing the analog-to-digital conversion detection module 20 from being damaged.
In addition, in some embodiments, as shown in fig. 1, the protection circuit 21 may include a first resistor 211 and a second resistor 212, one end of the first resistor 211 is electrically connected to the second pin 40, the other end of the first resistor 211 is electrically connected to the analog-to-digital converter 22, one end of the second resistor 212 is electrically connected between the first resistor 211 and the analog-to-digital converter 22, and the other end of the second resistor 212 is grounded.
In the case that the protection circuit 21 includes the first resistor 211 and the second resistor 212, when the first voltage pin 30 and the second pin 40 are connected, which is equivalent to the short circuit between the voltage pin 30 and the second pin 40, at this time, the current will flow into the second pin 40 from the first voltage pin 30. Since the second pin 40 is connected to one end of the first resistor 211 and one end of the second resistor 212 is electrically connected between the first resistor 211 and the adc 22, current flows through the first resistor 211 and the second resistor 212. Since the other end of the second resistor 212 is grounded, it is equivalent to that the first voltage pin 30, the second pin 40, the first resistor 211 and the second resistor 212 form a path, and at this time, the current flows out from the grounding point of the second resistor 212. When current flows through the first resistor 211 and the second resistor 212, a voltage is generated across both the first resistor 211 and the second resistor 212, and the first resistor 211 is connected in series with the second resistor 212, so that the first resistor 212 and the second resistor 212 can divide the voltage. That is, through the at least two resistors 211, when the voltage pin 30 is short-circuited with the second pin 40, the at least two resistors 211 can perform a voltage dividing function, so that the voltage on the analog-to-digital converter 22 is small, and the analog-to-digital converter 22 is prevented from being damaged by an excessive voltage.
It should be noted that, when the first voltage pin 30 and the second voltage pin 40 are not short-circuited, since no current passes through the first resistor 211 and the second resistor 212, the voltage detected by the analog-to-digital converter 22 is 0V. When the voltage pin 30 is short-circuited with the second pin 40, the voltage can be detected by the analog-to-digital converter 22, and the voltage detected by the analog-to-digital converter 22 can be the voltage on the second resistor 212 or the voltage on the first resistor 211. A first threshold voltage may be set in the adc 22, which indicates that the short circuit between the first voltage pin 30 and the second pin 40 is not serious and the connector 10 may not be processed when the voltage detected by the adc 22 is less than the first threshold voltage. When the voltage detected by the analog-to-digital converter 22 is greater than or equal to the first threshold voltage, indicating that the short circuit between the first voltage pin 30 and the second pin 40 is serious, the short circuit between the first voltage pin 30 and the signal pin 60 may occur, and at this time, the connector 10 needs to be processed.
The first threshold voltage may be 0.1V, and certainly, the preset voltage threshold may also be other values, such as 0.2V, which is not limited herein in the embodiment of the present invention. Among other things, handling the connector 10 refers to cleaning the conductive media in the connector, such as cleaning water and conductive debris that enter the connector.
In addition, in the embodiment of the present invention, since the voltage detected by the analog-to-digital converter 22 is the voltage across the first resistor 211 or the second resistor 212, the magnitude of the first threshold voltage can be adjusted by adjusting the resistance value of the first resistor 211 or the second resistor 212.
For example, when the analog-to-digital conversion detector 22 detects the voltage across the second resistor 212, since the first resistor 211 and the second resistor 212 are connected in series, the current magnitude in the first resistor 211 and the current magnitude in the second resistor 212 can be adjusted, and at this time, the resistance of the first resistor 211 is increased, the voltage across the first resistor 211 is increased, and the voltage across the second resistor 212 is decreased. When the resistance of the first resistor 211 becomes smaller, the voltage across the first resistor 211 becomes smaller, and the voltage across the second resistor 212 becomes larger. That is, by adjusting the resistance of the first resistor 211, the voltage across the second resistor 212 can be adjusted, and thus the first threshold voltage in the adc detector 22 can be adjusted.
In addition, in some embodiments, referring to fig. 3, a schematic diagram of another detection circuit provided by the embodiments of the present invention is shown, as shown in fig. 3, the first voltage pin 30 may include a first voltage sub-pin and a second voltage sub-pin, the second pin 40 includes a first sub-pin and a second sub-pin, the first sub-pin is disposed adjacent to the first voltage sub-pin, the second sub-pin is disposed adjacent to the second voltage sub-pin, and the first sub-pin and the second sub-pin are both electrically connected to the analog-to-digital conversion detection module 20.
It should be noted that the first voltage sub-pin and the second voltage sub-pin may be respectively disposed on two sides of the connector 10, and the first sub-pin and the second sub-pin may be respectively disposed on two sides of the connector 10. At this time, since the first sub-pin and the second sub-pin are both electrically connected to the analog-to-digital conversion detection module 20, the analog-to-digital conversion detection module 20 can detect the first voltage no matter the first voltage sub-pin is short-circuited with the first sub-pin or the second voltage sub-pin is short-circuited with the second sub-pin, so that it can be determined that the connector 10 fails.
For example, when the first voltage sub-pin and the second sub-pin are short-circuited, at this time, a voltage may be applied to the second sub-pin 40, and since the second sub-pin 40 is electrically connected to the analog-to-digital conversion detection module 20, at this time, the analog-to-digital conversion detection module 20 may detect the first voltage, thereby determining that the connector fails.
