In order to solve the problems, the power supply control device provided by the embodiment of the application is provided with the main power supply circuit and the standby power supply circuit, when the main power supply circuit is damaged, the power supply module supplies power to the SIM through the standby power supply circuit, and the processing capacity of the electronic equipment for coping with faults is improved.
Fig. 1 is a schematic structural diagram of a power supply control device according to an embodiment of the present application. As shown in fig. 1, the power supply control apparatus may include a power module 110, a SIM120, and a control device 130. The power module 110 is electrically connected to the SIM120 for powering the SIM 120. Specifically, the power module 110 is connected to the first pin of the SIM120 through a main power supply pin, and the power module 110 is connected to the first pin of the SIM120 through a standby power supply pin, where the standby power supply pin and the first pin are provided with the control device 130. The pin indicated by arrow 101 is the main power supply pin of the power module 110, the pin indicated by arrow 102 is the standby power supply pin of the power module 110, and the pin indicated by arrow 103 is the first pin of the SIM 120.
After the electronic device is turned on, the control device 130 is usually in an off state, and the power module 110 supplies power to the SIM120 through the main power supply pin. If the path between the main power supply pin and the first pin is damaged, the control device 130 is turned on, and the power module 110 supplies power to the SIM120 through the standby power supply pin, so as to ensure the normal operation of the SIM.
In one embodiment, the electronic device may be configured as shown in fig. 2, comprising: power chip 210, processor 220, SIM230, and MOS transistor 240. The control device between the standby power supply pin and the first pin is realized by an MOS tube 240, the processor is connected with the grid electrode of the MOS tube 240, and the MOS tube 240 is controlled to be turned off or turned on by changing the grid voltage of the MOS tube 240.
After power-up operation of SIM230, processor 220 may identify SIM230 and confirm that SIM230 may operate properly. If the processor 220 detects that the SIM230 cannot be identified after the electronic device is powered on, or the 44 person suddenly detects that the SIM230 cannot be identified during normal operation of the SIM230, it may be preliminarily determined that the path between the main power supply pin and the first pin is damaged, and the power chip 210 cannot supply power to the SIM230 through the main power supply pin. For the emergency, the processor 220 controls the MOS transistor 240 to be turned on, and the power chip 210 supplies power to the SIM230 through the standby power pin.
The power chip 210 is provided with a plurality of pins, wherein the pin indicated by arrow 201 is a main power supply pin, the main power supply pin is connected with a first pin of the SIM230, the pin indicated by arrow 203 is a first pin, the pin indicated by arrow 202 is a standby power supply pin, the standby power supply pin is used for connecting the MOS tube 240, and the other end of the MOS tube 240 is connected with the SIM230.

If processor 220 detects that SIM230 is not identifiable, a default rescue operation is typically performed, i.e., control power chip 210 ceases to supply power to SIM230, and then, at control power chip 210, SIM230 is again powered by the main power circuit, again identifying SIM230. After repeating the rescue operation a plurality of times, if SIM230 is still not recognized, it may be preliminarily determined that the path between the main power pin and the first pin is damaged. In order to ensure normal operation of SIM230, processor 220 outputs a second voltage to the gate of MOS transistor 240, the second voltage being greater than or equal to the threshold voltage, the MOS transistor is turned on, and power chip 210 may supply power to SIM230 via the standby power pin.
In the embodiment of the application, the control device is realized through the MOS tube 240, and the processor 220 can control the MOS tube 240 to be turned off or turned on only by outputting different voltages to the grid electrode of the MOS tube 240, so that other modifications to hardware circuits are not required, and the hardware cost is saved.

Step 303, determining whether the SIM can be identified.
After each rescue operation is executed, the processor identifies the SIM again and determines whether the identification is successful, if so, the whole process is ended, otherwise, step 304 is entered.
Step 304, determining whether the number of rescue operations exceeds a preset threshold.
If the number of the rescue operations does not exceed the preset threshold, the rescue operation is continuously executed, otherwise, step 305 is entered.
And 305, controlling the conduction of the MOS transistor.
The SIM can not be identified after the card is saved for many times, and the processor can control the MOS tube to be conducted so that the power module supplies power to the SIM through the standby power supply circuit. Specifically, the processor changes the gate voltage of the MOS tube to enable the MOS tube to be conducted.
Step 306, identify the SIM.
The processor identifies the SIM again, and the whole process is finished after the identification is successful.
In the embodiment of the application, when the processor cannot identify the SIM, the rescue operation is firstly executed, and if the rescue card cannot be identified for a plurality of times, the standby power supply circuit is controlled to be conducted, so that the power supply module supplies power to the SIM through the standby power supply circuit, and the normal operation of the equipment is ensured.

Similarly, the anode voltage and the cathode voltage of the second diode 440 are the voltage of the clock pin and the voltage of the main power supply pin, respectively, the second diode 440 is in an off state, the anode voltage and the cathode voltage of the third diode 450 are the voltage of the reset pin and the voltage of the main power supply pin, respectively, and the third diode 450 is in an off state.
When the main power supply circuit is accidentally damaged, the cathode voltage of the first diode 430 is 0, the anode voltage is still the voltage of the data pin, and since the anode voltage is greater than the cathode voltage, the first diode 430 is turned on, the current of the data pin can flow through the first diode 430 to reach the SIM420, and the power chip 410 can supply power to the SIM420 through the data pin. Similarly, the cathode voltage of the second diode is 0, the anode voltage is still the voltage of the clock pin, the anode voltage is greater than the cathode voltage, the second diode 440 is conducted, the current of the clock pin can flow through the second diode 440 and then reach the SIM420, and the power chip 410 can supply power to the SIM420 through the clock pin; the cathode voltage of the third diode is 0, the anode voltage is still the voltage of the reset pin, the anode voltage is larger than the cathode voltage, the third diode 450 is conducted, the current of the reset pin can flow through the third diode 450 to reach the SIM420, and the power chip can supply power to the SIM420 through the reset pin.
In the embodiment of the present application, the data pin on the power chip 410 is connected to the data pin on the SIM420 before, and the power chip 410 can perform data transmission with the SIM420 based on the data pin. On this basis, a lead is additionally led out at the data pin of the power chip 410 to connect with a diode, which in turn connects with the first pin of the SIM 420. The two branches led out by the data pins work in parallel, so that the data transmission is not affected, the function of a standby power supply pin can be realized, a new pin is not required to be arranged, and the hardware cost is saved. Similarly, the clock pin and the reset pin draw out a new branch on the original branch, so that the function of the standby power supply pin is realized.
In the embodiment of the application, the lead is led out from other circuits and the diode is arranged, so that the diode can be conducted when the main power supply circuit is damaged, the power supply chip supplies power to the SIM through other circuits, and the normal operation of the SIM is ensured.
