An embodiment of the present application provides a switching power supply detection circuit, and referring to fig. 1, fig. 1 is a block diagram of a first embodiment of the switching power supply detection circuit according to the present application. The switch power supply detection circuit comprises a control module 10, a temperature detection module 20, a voltage detection module 30, a switch power supply module 40 and a standby power supply module 50, wherein a power supply port 400 of the switch power supply module 40 is packaged with a switch unit 401; the control module 10 is respectively connected with the temperature detection module 20, the voltage detection module 30 and the standby power module 50, the temperature detection module 20 is fixedly connected with the switching power module 40, the voltage detection module 30 is connected with the switching power module 40 in parallel, and the control module 10 is connected with the switching power module 40 through the switching unit 401.
The voltage detection module 30 is configured to obtain an output voltage of the switching power supply module 40, and send the output voltage to the control module 10 when the output voltage does not match a minimum charging voltage of the switching power supply module 40.
In this embodiment, after determining that the switching power supply module 40 is connected to the load device through the power supply port in which the switching unit 401 is packaged, the output voltage of the switching power supply module 40 is obtained according to the voltage detection module 30 connected in parallel with the switching power supply module 40, and whether the output voltage is smaller than the minimum charging voltage of the switching power supply module 40 is detected, if the output voltage is smaller than the minimum charging voltage of the switching power supply module 40, the output voltage is not matched with the minimum charging voltage of the switching power supply module 40, and the output voltage is rapidly sent to the control module 10, so that effective monitoring of the output voltage of the switching power supply module is achieved.
It should be noted that, the minimum charging voltage may be customized according to the requirement of the user, and since the output voltage of the switching power module 40 decreases with the increase of the temperature, the minimum charging voltage may be understood as the normal voltage data output by the switching power module 40 under the condition of the maximum high temperature tolerance.
In yet another embodiment, if the output voltage is greater than or equal to the minimum charging voltage of the switching power supply module 40, the output voltage is matched with the minimum charging voltage of the switching power supply module 40, and it is determined that the output voltage of the switching power supply module 40 is normally used for supplying power to the load device.
The control module 10 is configured to output a temperature detection command to the temperature detection module 20 in response to the output voltage; the temperature detection module 20 is configured to determine temperature data of the switching power supply module 40 according to the temperature detection instruction, and output a low-level signal to the control module 10 in response to the temperature data when the temperature data does not match a maximum temperature threshold corresponding to the switching power supply module 40, so that the control module 10 forwards the low-level signal to the switching unit;
in this embodiment, according to the connection between the control module 10 and the voltage detection module 30, after receiving the output voltage sent by the voltage detection module 30, the control module 10 responds to the output voltage to output a temperature detection command to the temperature detection module 20. At this time, according to the response of the temperature detection module 20 to the temperature detection instruction, the temperature data of the switching power supply module 40 is determined, and whether the temperature data is greater than the maximum temperature threshold corresponding to the switching power supply module 40 is determined, if the temperature data is greater than the maximum temperature threshold corresponding to the switching power supply module 40, it is determined that the temperature data is not matched with the maximum temperature threshold corresponding to the switching power supply module 40, and the temperature detection module 20 responds to the temperature data and outputs a low level signal to the control module 10, so that the control module 10 forwards the low level signal to the switching unit 401, thereby effectively monitoring the abnormal temperature data of the switching power supply module 40.
In yet another embodiment, if the temperature data is less than or equal to the maximum temperature threshold value corresponding to the switching power supply module 40, it is determined that the temperature data matches the maximum temperature threshold value corresponding to the switching power supply module 40, so as to avoid the occurrence of unstable output voltage of the switching power supply module 40 in the high temperature tolerance range due to signal jump, that is, it is determined that the output voltage of the switching power supply module 40 under the temperature data normally supplies power to the load device.
The switching unit 401 is configured to adjust a power supply operation state of the switching power supply module 40 to a power supply stop state according to the low level signal, and upload the power supply stop state to the control module 10; the control module 10 is further configured to output a high-level signal to the standby power module 50 in response to the power supply stop state, so that the standby power module 50 charges the load device according to the standby voltage data output by the high-level signal.
In this embodiment, after the control module 10 sends the low-level signal to the switch unit 401, the switch unit adjusts the power supply running state of the switch power module 40 to the power supply stop state according to the low-level signal, so as to avoid the damage of the switch power module 40 caused by over temperature and effectively improve the service life of the switch power module 40, and then upload the power supply stop state to the control module 10, the control module 10 responds to the power supply stop state to rapidly output the high-level signal to the standby power module 50, so that the standby power module 50 charges the load device according to the standby voltage data timely output by the high-level signal, thereby avoiding the occurrence of the phenomenon that the switch power cannot normally supply power due to the influence of temperature, and further effectively improving the power supply adjustment capability of the switch power.
Further, in some possible embodiments, referring to fig. 2, fig. 2 is a schematic diagram of a temperature detection module according to an embodiment of the switching power supply detection circuit of the present application. The temperature detection module comprises a thermistor RP, a first resistor R1, a second resistor R2, a third resistor R3 and a photoelectric coupler U1, and the thermistor RP is fixedly connected with the switching power supply module 40; the first end of the thermistor RP is respectively connected with the first end of the first resistor R1 and the first end of the second resistor R2, the second end of the first resistor R1 is connected with a power supply end, the second end of the second resistor R2 is connected with the first end of the photoelectric coupler U1, and the second end of the thermistor R1, the second end of the photoelectric coupler U1 and the third end of the photoelectric coupler U1 are respectively grounded; the fourth end of the photocoupler U1 is connected to the first end of the third resistor R3 and the control module 10, and the second end of the third resistor R3 is connected to the power supply end.
In this embodiment, when the temperature of the switching power supply module 40 is higher, the resistance of the thermistor RP is smaller and smaller, so that the voltage of the thermistor RP is smaller and smaller, when the temperature data of the switching power supply module 40 exceeds the maximum temperature threshold corresponding to the switching power supply module 40, the voltage data of the thermistor RP cannot make the light emitting diode inside the photo coupler U1 conduct and emit light (i.e., the voltage data of the thermistor RP is output to the second resistor R2, the generated current data is negligible), the third end of the photo coupler U1 is determined to output a low level signal to the control module according to the non-light emitting information of the photo coupler U1, so that the switching unit 401 adjusts the power supply running state of the switching power supply module 40 to a power supply stop state according to the low level signal forwarded by the control module, thereby avoiding the phenomenon that the switching power supply module 40 is damaged due to over temperature and effectively improving the service life of the switching power supply module 40, and then the control module 10 responds to the stop state and rapidly outputs a high level signal to the standby power supply 50 to the standby power supply 50, thereby avoiding the phenomenon that the standby power supply power 50 cannot be adjusted due to the high level signal.
