Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application.
All other embodiments that can be obtained by a person skilled in the art without inventive step based on the embodiments in this application are within the scope of protection of this application.
Referring to fig. 1, fig. 1 is a block diagram of a power failure detection apparatus 100 according to a preferred embodiment of the present application. The power failure detection apparatus 100 is electrically connected to the power supply unit 200 for detecting a failure type of the power supply unit 200.
The power supply unit 200 is used for supplying power to electronic components (not shown). In this embodiment, the power supply unit 200 will output a status signal to the power failure detection apparatus 100 when in an abnormal state.
In the present embodiment, the power failure detection apparatus 100 includes a control unit 10, a conversion unit 20, and a test unit 30. The control unit 10 is electrically connected between the power supply unit 200 and the conversion unit 20, and the test unit 30 is electrically connected to the conversion unit 20.
The control unit 10 is configured to receive the status signal output by the power supply unit 200, and output a current to the converting unit 20 according to the status signal.
The converting unit 20 is configured to receive the current output by the control unit 10 and convert the current into a voltage.
The test unit 30 is used for measuring the voltage. In the present embodiment, the test unit 30 may be a multimeter.
The types of faults occurring when the power supply unit 200 operates may be an overvoltage state, an undervoltage state, an overcurrent state, and an overtemperature state.
Specifically, the overvoltage state of the power supply unit 200 may be understood as an abnormal state caused by the voltage of the output of the power supply unit 200 exceeding a first voltage preset value. The under-voltage state of the power supply unit 200 can be understood as an abnormal state caused by the voltage output by the power supply unit 200 being lower than a second voltage preset value. The overcurrent state of the power supply unit 200 can be understood as an abnormal state caused by the current output by the power supply unit 200 exceeding a preset current value. The over-temperature state of the power supply unit 200 may be understood as an abnormal state caused by the temperature of the power supply unit 200 exceeding a preset temperature value.
When the power supply unit 200 is in an overvoltage state, i.e. the voltage exceeds a first voltage preset value, the power supply unit 200 will output a first state signal to the control unit 10, the control unit 10 will output a first current (e.g. 10mA) to the converting unit 20 according to the first state signal, and the converting unit 20 converts the first current into a first voltage (e.g. 1V).
When the power supply unit 200 is in an under-voltage state, i.e. the voltage is lower than a second voltage preset value, the power supply unit 200 will output a second state signal to the control unit 10, the control unit 10 will output a second current (e.g. 20mA) to the converting unit 20 according to the second state signal, and the converting unit 20 converts the second current into a second voltage (e.g. 2V).
When the power supply unit 200 is in an overcurrent state, that is, the current exceeds a preset current value, the power supply unit 200 outputs a third state signal to the control unit 10, the control unit 10 outputs a third current (e.g., 30mA) to the converting unit 20 according to the third state signal, and the converting unit 20 converts the third current into a third voltage (e.g., 3V).
When the power supply unit 200 is in an over-temperature state, i.e. the temperature exceeds a preset temperature value, the power supply unit 200 outputs a fourth state signal to the control unit 10, the control unit 10 outputs a fourth current (e.g. 40mA) to the converting unit 20 according to the fourth state signal, and the converting unit 20 converts the fourth current into a fourth voltage (e.g. 4V).
Therefore, the user can determine the fault type of the power supply unit 200 according to the acquired voltage and a preset corresponding relationship. Wherein, the preset corresponding relation describes that: a correspondence between a fault type and a voltage value may be established in advance.
Thus, the voltage values obtained by the test unit 30 can be compared with the voltage values in the preset corresponding relationship one by one, and the fault type of the power supply unit 200 can be identified.
Referring to fig. 2, fig. 2 is a circuit diagram of a power failure detection apparatus 100 according to a preferred embodiment of the present application.
In this embodiment, the control unit 10 may include a control chip U1, and the converting unit 20 may include a resistor R1. The control chip U1 may include a first pin 1, a second pin 2, a third pin 3, and a fourth pin 4.
The first pin 1, the second pin 2, the third pin 3 and the fourth pin 4 of the control chip U1 are all grounded through the resistor R1.
The operation of the power failure detection apparatus 100 of the present application will be described in detail with reference to the circuit diagram shown in fig. 2.
When the power supply unit 200 has an overvoltage fault, the power supply unit 200 outputs a first state signal to the control chip U1, so that the first pin 1 of the control chip U1 outputs a current of 10mA to the resistor R1, the resistance of the resistor R1 may be 100ohm, and at this time, the current of 10mA may generate a voltage of 1V at two ends of the resistor R1. Therefore, a user can measure the voltage of 1V through a multimeter and compare the preset corresponding relation, so that the fault cause of the power supply unit 200 can be identified as overvoltage.
When the power supply unit 200 has an undervoltage fault, the power supply unit 200 outputs a second status signal to the control chip U1, so that the second pin 2 of the control chip U1 outputs a 20mA current to the resistor R1, and at this time, the 20mA current may generate a voltage of 2V across the resistor R1. Therefore, a user can measure the voltage of 2V through a multimeter and compare the preset corresponding relation, so that the fault reason of the power supply unit 200 can be identified as undervoltage.
When the power supply unit 200 has an overcurrent fault, the power supply unit 200 outputs a third status signal to the control chip U1, so that the third pin 3 of the control chip U1 outputs a current of 30mA to the resistor R1, and at this time, the current of 30mA can generate a voltage of 3V across the resistor R1. Therefore, a user can measure the voltage of 3V through a multimeter and compare the preset corresponding relation, so that the fault reason of the power supply unit 200 can be identified as overcurrent.
When the temperature of the power unit 200 is too high, the power unit 200 will output a fourth status signal to the control chip U1, so that the fourth pin 4 of the control chip U1 will output a current of 40mA to the resistor R1, and at this time, the current of 40mA can generate a voltage of 4V across the resistor R1. Therefore, a user can measure the voltage of 4V through a multimeter and compare the preset corresponding relation, so that the fault reason of the power supply unit 200 can be identified as the reason of overhigh temperature.
In the power failure detection apparatus 100 provided in the above embodiment, the control unit 10 receives the status signal output by the power unit 200, outputs a corresponding current to the conversion unit 20, and measures the voltage output by the conversion unit 20 through the test unit 30, so as to identify the failure type of the power supply according to the voltage values with different magnitudes. Thus, the power failure detection apparatus 100 according to the embodiment of the present disclosure can identify the failure type of the power supply, so as to effectively reduce the debugging time of the power failure and facilitate the user to use the power failure detection apparatus.
It should be understood by those skilled in the art that the above embodiments are only for illustrating the present application and are not used as limitations of the present application, and that suitable modifications and changes of the above embodiments are within the scope of the claims of the present application as long as they are within the spirit and scope of the present application.
