[0029] The wireless fidelity module and electronic device provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0030] The wireless fidelity module provided in the embodiment of the present application includes: a wireless fidelity chip, multiple front-end modules and multiple detection modules; the multiple front-end modules and the multiple detection modules correspond to each other one by one; the first detection module is arranged between the power supply end of the first front-end module and the power supply, the first detection module is any one of the multiple detection modules, and the first front-end module is a front-end module corresponding to the first detection module; the first detection module is used to ensure that the other front-end modules except the first front-end module in the multiple front-end modules work normally when the first front-end module is abnormal; the first signal end of the first front-end module is connected to one of the multiple signal ends of the wireless fidelity chip, and the second signal end of the first front-end module is connected to the antenna.

[0031] In the embodiment of the present application, when one front-end module is abnormal, other front-end modules can also work normally.

[0032] like Figure 1 As shown, Figure 1 1 is a schematic diagram of the first structure of the wireless fidelity module provided in the embodiment of the present application. Figure 1 In the embodiment, the Wi-Fi module 100 includes: a Wi-Fi chip 101, N front-end modules 102 and N detection modules 103, wherein N is a positive integer greater than or equal to 2.

[0033] The i-th detection module 103 is disposed between the power supply terminal Vcc of the i-th front-end module 102 corresponding to the i-th detection module 103 and the power supply 104. The first signal terminal of the i-th front-end module 102 is connected to the i-th signal terminal of the Wi-Fi chip 101, and the second signal terminal of the i-th front-end module 102 is connected to the i-th antenna 105. i is a positive integer not greater than N.

[0034] When the i-th front-end module 102 is abnormal, the i-th detection module 103 can ensure that the other front-end modules among the N front-end modules except the i-th front-end module 102 operate normally.

[0035] In some possible implementations of the embodiments of the present application, the wireless fidelity chip includes multiple general purpose input and output (GPIO) groups, and the multiple GPIO groups correspond to multiple detection modules one by one; the first detection module includes: a first switch and a comparator; the first end of the first switch is electrically connected to the power supply end of the first front-end module and the first input end of the comparator respectively; the second end of the first switch is electrically connected to the power supply; the control end of the first switch is electrically connected to the output end of the comparator and the first GPIO included in the first GPIO group respectively; the first GPIO group is the GPIO group corresponding to the first detection module; the second input end of the comparator is grounded; when the output end of the comparator outputs a low level, the first switch is disconnected; when the output end of the comparator outputs a high level, the first switch is turned on.

[0036] like Figure 2 As shown, Figure 2 1 is a schematic diagram of the second structure of the wireless fidelity module provided in the embodiment of the present application. Figure 2 In the embodiment, the detection module 103 includes a first switch 1031 and a comparator 1032 .

[0037] The first end of the first switch 1031 is electrically connected to the power supply terminal Vcc of the front-end module 102 and the first input terminal of the comparator 1032, respectively, and the second end of the first switch 1031 is electrically connected to the power supply 104; the control end of the first switch 1031 is electrically connected to the output end of the comparator 1032 and GPIO1 in the GPIO group corresponding to the detection module 103, respectively; the second end of the comparator 1032 is grounded.

[0038] When the Wi-Fi module 100 is powered on, the Wi-Fi chip 101 outputs a high level through GPIO1, and the first switch 1031 is turned on. When the front-end module 102 works normally, the comparator 1032 outputs a high level to keep the first switch 1031 turned on. When the front-end module 102 is abnormal (for example, the front-end module is burned out, and the power supply terminal Vcc of the front-end module is short-circuited to the ground), the comparator 1032 outputs a low level, the first switch 1031 is turned off, and the power supply path from the power supply 104 to the front-end module 102 is disconnected, and the power supply 104 no longer supplies power to the front-end module 102.

[0039] In the embodiment of the present application, by disconnecting the power supply path from the power supply to the front-end module where the abnormality occurs, it is possible to ensure that other front-end modules among the multiple front-end modules except the front-end module where the abnormality occurs operate normally.

[0040] In some possible implementations of the embodiments of the present application, the first detection module also includes: a second switch; the first end of the second switch is electrically connected to the second end of the first switch; the second end of the second switch is electrically connected to the power supply; the control end of the second switch is electrically connected to the second GPIO included in the first GPIO group; when the wireless fidelity chip determines through the first GPIO that the output end of the comparator outputs a low level more times than the first number, the wireless fidelity chip controls the second switch to disconnect through the second GPIO.

[0041] like Figure 3 As shown, Figure 3 is a third structural diagram of the wireless fidelity module provided in the embodiment of the present application. Figure 3 In the embodiment, the detection module 103 includes a first switch 1031 , a second switch 1033 and a comparator 1032 .

[0042] The first end of the first switch 1031 is electrically connected to the power supply terminal Vcc of the front-end module 102 and the first input terminal of the comparator 1032, respectively; the second end of the first switch 1031 is electrically connected to the first end of the second switch 1033, and the second end of the second switch 1033 is electrically connected to the power supply 104; the control end of the first switch 1031 is electrically connected to the output end of the comparator 1032 and GPIO1 in the GPIO group corresponding to the detection module 103, respectively; the second end of the comparator 1032 is grounded; and the control end of the second switch 1033 is electrically connected to GPIO2 in the GPIO group.

[0043] When the Wi-Fi module 100 is powered on, the Wi-Fi chip 101 outputs a high level through GPIO1 and GPIO2, and the first switch 1031 and the second switch 1033 are turned on. When the front-end module 102 is working normally, the comparator 1032 outputs a high level to keep the first switch 1031 turned on. When the front-end module 102 is abnormal (for example, the front-end module is burned out, and the power supply terminal Vcc of the front-end module is short-circuited to the ground), the comparator 1032 outputs a low level, the first switch 1031 is turned off, the Wi-Fi chip 101 detects that the comparator 1032 outputs a low level through GPIO1, the Wi-Fi chip 101 outputs a low level through GPIO2, the second switch 1033 is turned off, the power supply path from the power supply 104 to the front-end module 102 is disconnected, and the power supply 104 no longer supplies power to the front-end module 102.

[0044] After the second switch 1033 is turned off for a period of time, the Wi-Fi chip 101 outputs a high level through GPIO1 and GPIO2, and the first switch 1031 and the second switch 1033 are turned on. If the comparator 1032 still outputs a low level at this time, the first switch 1031 is turned off, the Wi-Fi chip 101 detects that the comparator 1032 outputs a low level through GPIO1, the Wi-Fi chip 101 outputs a low level through GPIO2, the second switch 1033 is turned off, the power supply path from the power supply 104 to the front-end module 102 is disconnected, and the power supply 104 no longer supplies power to the front-end module 102. If the comparator 1032 outputs a high level, the first switch 1031 is kept turned on, and the front-end module 102 works normally.

[0045] When the Wi-Fi chip 101 detects through GPIO1 that the comparator 1032 outputs a low level for a number greater than the first number, it indicates that the front-end module 102 is irreversibly damaged. At this time, the Wi-Fi chip 101 continuously outputs a low level through GPIO2, and the second switch 1033 is continuously disconnected, and the front-end module 102 is no longer powered.

[0046] In an embodiment of the present application, by detecting the level of the comparator output, when the level of the comparator output is low for multiple times, it indicates that the front-end module is damaged and cannot be recovered. At this time, the power supply path from the power supply to the front-end module is continuously disconnected, and the power supply no longer supplies power to the front-end module, thereby reducing misjudgment of the front-end module.

[0047] In some possible implementations of the embodiments of the present application, the first detection module further includes: a first voltage stabilizing unit; two ends of the first voltage stabilizing unit are electrically connected to the output end of the comparator and the ground respectively.

[0048] like Figure 4 As shown, Figure 4 FIG. 4 is a fourth structural diagram of the wireless fidelity module provided in the embodiment of the present application. In FIG. 4 , the detection module 103 includes a first switch 1031 , a comparator 1032 and a first voltage stabilizing unit 1034 .

[0049] The first end of the first switch 1031 is electrically connected to the power supply terminal Vcc of the front-end module 102 and the first input terminal of the comparator 1032, respectively, and the second end of the first switch 1031 is electrically connected to the power supply 104; the control end of the first switch 1031 is electrically connected to the output end of the comparator 1032, the first end of the first voltage stabilizing unit 1034, and GPIO1 in the GPIO group corresponding to the detection module 103; the second end of the comparator 1032 is grounded; and the second end of the first voltage stabilizing unit 1034 is grounded.

[0050] When the Wi-Fi module 100 is powered on, the Wi-Fi chip 101 outputs a high level through GPIO1 and GPIO2, and the first switch 1031 and the second switch 1033 are turned on. When the front-end module 102 is working normally, the comparator 1032 outputs a high level to keep the first switch 1031 turned on. When the front-end module 102 is abnormal (for example, the front-end module is burned out, and the power supply terminal Vcc of the front-end module is short-circuited to the ground), the comparator 1032 outputs a low level, the first switch 1031 is turned off, the Wi-Fi chip 101 detects that the comparator 1032 outputs a low level through GPIO1, the Wi-Fi chip 101 outputs a low level through GPIO2, the second switch 1033 is turned off, the power supply path from the power supply 104 to the front-end module 102 is disconnected, and the power supply 104 no longer supplies power to the front-end module 102.

[0051] In some possible implementations of the embodiments of the present application, the first voltage stabilizing unit 1034 is used to stabilize the voltage at the control end of the first switch 1031 to prevent the pulse voltage at the control end of the first switch 1031 from damaging the first switch 1031 .

[0052] In the embodiment of the present application, the voltage stabilizing unit can prevent the switch from being damaged, thereby ensuring the normal operation of the front-end module.

[0053] In some possible implementations of the embodiments of the present application, the first detection module further includes: a first resistor; the first resistor is arranged between the second input terminal of the comparator and the ground.

[0054] like Figure 5 As shown, Figure 5 is a fifth structural diagram of the wireless fidelity module provided in the embodiment of the present application. Figure 5 In the embodiment, the detection module 103 includes a first switch 1031 , a comparator 1032 and a resistor R1 .

[0055] The first end of the first switch 1031 is electrically connected to the power supply terminal Vcc of the front-end module 102 and the first input terminal of the comparator 1032, respectively, and the second end of the first switch 1031 is electrically connected to the power supply 104; the control end of the first switch 1031 is electrically connected to the output end of the comparator 1032 and the GPIO1 in the GPIO group corresponding to the detection module 103, respectively; the second end of the comparator 1032 is electrically connected to one end of the resistor R1, and the other end of the resistor R1 is grounded.

[0056] When the Wi-Fi module 100 is powered on, the Wi-Fi chip 101 outputs a high level through GPIO1 and GPIO2, and the first switch 1031 and the second switch 1033 are turned on. When the front-end module 102 is working normally, the comparator 1032 outputs a high level to keep the first switch 1031 turned on. When the front-end module 102 is abnormal (for example, the front-end module is burned out, and the power supply terminal Vcc of the front-end module is short-circuited to the ground), the comparator 1032 outputs a low level, the first switch 1031 is turned off, the Wi-Fi chip 101 detects that the comparator 1032 outputs a low level through GPIO1, the Wi-Fi chip 101 outputs a low level through GPIO2, the second switch 1033 is turned off, the power supply path from the power supply 104 to the front-end module 102 is disconnected, and the power supply 104 no longer supplies power to the front-end module 102.

[0057] In some possible implementations of the embodiment of the present application, the resistor R1 is used to stabilize the level of the second input terminal of the comparator 1032 .

[0058] Figure 6 1 is a schematic diagram of the first specific structure of the wireless fidelity module provided in the embodiment of the present application. Figure 6 In the embodiment, the detection module 103 includes a first switch 1031, a comparator 1032, a second switch 1033, a first voltage stabilizing unit 1034 and a resistor R1.

[0059] The first end of the first switch 1031 is electrically connected to the power supply terminal Vcc of the front-end module 102 and the first input terminal of the comparator 1032, respectively; the second end of the first switch 1031 is electrically connected to the first end of the second switch 1033; the control end of the first switch 1031 is electrically connected to the output end of the comparator 1032, the first end of the first voltage stabilizing unit 1034, and GPIO1 in the GPIO group corresponding to the detection module 103, respectively; the second end of the second switch 1033 is electrically connected to the power supply 104; the control end of the second switch 1033 is electrically connected to GPIO2 in the GPIO group; the second input end of the comparator 1032 is electrically connected to the first end of the resistor R1; the second end of the resistor R1 and the second end of the first voltage stabilizing unit 1034 are grounded.

[0060] When the Wi-Fi module 100 is powered on, the Wi-Fi chip 101 outputs a high level through GPIO1 and GPIO2, and the first switch 1031 and the second switch 1033 are turned on. When the front-end module 102 is working normally, the comparator 1032 outputs a high level to keep the first switch 1031 turned on. When the front-end module 102 is abnormal (for example, the front-end module is burned out, and the power supply terminal Vcc of the front-end module is short-circuited to the ground), the comparator 1032 outputs a low level, the first switch 1031 is turned off, the Wi-Fi chip 101 detects that the comparator 1032 outputs a low level through GPIO1, the Wi-Fi chip 101 outputs a low level through GPIO2, the second switch 1033 is turned off, the power supply path from the power supply 104 to the front-end module 102 is disconnected, and the power supply 104 no longer supplies power to the front-end module 102.

[0061] After the second switch 1033 is turned off for a period of time, the Wi-Fi chip 101 outputs a high level through GPIO1 and GPIO2, and the first switch 1031 and the second switch 1033 are turned on. If the comparator 1032 still outputs a low level at this time, the first switch 1031 is turned off, the Wi-Fi chip 101 detects that the comparator 1032 outputs a low level through GPIO1, the Wi-Fi chip 101 outputs a low level through GPIO2, the second switch 1033 is turned off, the power supply path from the power supply 104 to the front-end module 102 is disconnected, and the power supply 104 no longer supplies power to the front-end module 102. If the comparator 1032 outputs a high level, the first switch 1031 is kept turned on, and the front-end module 102 works normally.

[0062] When the Wi-Fi chip 101 detects through GPIO1 that the comparator 1032 outputs a low level for a number greater than the first number, it indicates that the front-end module 102 is irreversibly damaged. At this time, the Wi-Fi chip 101 continuously outputs a low level through GPIO2, and the second switch 1033 is continuously disconnected, and the front-end module 102 is no longer powered.

[0063] In some possible implementations of the embodiments of the present application, the first detection module includes: a third switch, a second resistor, a differential voltage amplifier and a single-pole double-throw switch; the first end of the third switch is electrically connected to the power supply end of the first front-end module; the second end of the third switch is respectively connected to the first end of the second resistor and the first input end of the differential voltage amplifier; the control end of the third switch is electrically connected to the second fixed end of the single-pole double-throw switch; the second end of the second resistor is respectively electrically connected to the second input end of the differential voltage amplifier and the first fixed end of the single-pole double-throw switch; the output end of the differential voltage amplifier is electrically connected to the control end of the single-pole double-throw switch; the moving end of the single-pole double-throw switch is connected to the power supply; when the output end of the differential voltage amplifier outputs a high level, the moving end of the single-pole double-throw switch is connected to the second fixed end of the single-pole double-throw switch, and the third switch is disconnected; when the output end of the differential voltage amplifier outputs a low level, the moving end of the single-pole double-throw switch is connected to the first fixed end of the single-pole double-throw switch, and the third switch is turned on.

[0064] like Figure 7 As shown, Figure 7 6 is a schematic diagram of the structure of the wireless fidelity module provided in the embodiment of the present application. Figure 7 In the embodiment, the detection module 103 includes: a third switch 1035 , a resistor R2 , a differential voltage amplifier 1036 and a single-pole double-throw switch 1037 .

[0065] The first end of the third switch 1035 is electrically connected to the power supply terminal Vcc of the front-end module 102; the second end of the third switch 1035 is respectively connected to the first end of the resistor R2 and the first input end of the differential amplifier 1036; the control end of the third switch 1035 is electrically connected to the second fixed end P2 of the single-pole double-throw switch 1037; the second end of the resistor R2 is respectively electrically connected to the second input end of the differential amplifier 1036 and the first fixed end P1 of the single-pole double-throw switch 1037; the output end of the differential amplifier 1036 is electrically connected to the control end of the single-pole double-throw switch 1037; the moving end P3 of the single-pole double-throw switch 1037 is connected to the power supply 104.

[0066] In the initial state, the moving end P3 of the single-pole double-throw switch 1037 is connected to the first fixed end P1 of the single-pole double-throw switch 1037. When the Wi-Fi module 100 is powered on, the control end of the third switch 1035 is at a low level, and the third switch 1035 is turned on. When the front-end module 102 is normal, the voltage difference across the resistor R2 is normal, and the differential amplifier 1036 outputs a low level, keeping the moving end P3 of the single-pole double-throw switch 1037 and the first fixed end P1 of the single-pole double-throw switch 1037 connected.

At this time, the third switch 1035 is disconnected, the active end P3 of the single-pole double-throw switch 1037 and the first fixed end P1 of the single-pole double-throw switch 1037 are also not conductive, the power supply path from the power supply 104 to the front-end module 102 is disconnected, and the power supply 104 no longer supplies power to the front-end module 102.

[0067] In the embodiment of the present application, by disconnecting the power supply path from the power supply to the front-end module where the abnormality occurs, it is possible to ensure that other front-end modules among the multiple front-end modules except the front-end module where the abnormality occurs operate normally.

[0068] In some possible implementations of the embodiments of the present application, the wireless fidelity chip includes multiple GPIOs, and the multiple GPIOs correspond to multiple detection modules one by one; the first detection module also includes: a fourth switch; a first end of the fourth switch is electrically connected to a power supply; a second end of the fourth switch is electrically connected to a control end of a single-pole double-throw switch and the GPIO corresponding to the first detection module, respectively; the control end of the fourth switch is electrically connected to an output end of a differential voltage amplifier; when the output end of the differential voltage amplifier outputs a high level more than a second number of times, the wireless fidelity chip controls the moving end of the single-pole double-throw switch and the second fixed end of the single-pole double-throw switch to be continuously turned on through the GPIO corresponding to the first detection module, and the third switch is continuously turned off.

[0071] When the Wi-Fi module 100 is powered on, the GPIO outputs a low level, the control end of the SPDT switch 1037 is at a low level, the moving end P3 of the SPDT switch 1037 is connected to the first fixed end P1 of the SPDT switch 1037, the control end of the third switch 1035 is at a low level, and the third switch 1035 is turned on. When the front-end module 102 is normal, the voltage difference across the resistor R2 is normal, the differential amplifier 1036 outputs a low level, the fourth switch 1038 is disconnected, the control end of the SPDT switch 1037 is at a low level, the moving end P3 of the SPDT switch 1037 is kept connected to the first fixed end P1 of the SPDT switch 1037, and the third switch 1035 is turned on. When the front-end module 102 is abnormal (for example, the front-end module is burned out, and the power supply terminal Vcc of the front-end module is short-circuited to the ground), the voltage difference across the resistor R2 increases, the differential amplifier 1036 outputs a high level, the control terminal of the fourth switch 1038 is at a high level, the fourth switch 1038 is turned on, the control terminal of the single-pole double-throw switch 1037 is at a high level, the moving terminal P3 of the single-pole double-throw switch 1037 is turned on with the second fixed terminal P2 of the single-pole double-throw switch 1037, the control terminal of the third switch 1035 is at a high level, and the third switch 1035 is turned off.

[0072] After a period of time, the voltage difference across the resistor R2 returns to normal, the differential amplifier 1036 outputs a low level, the fourth switch 1038 is turned off, the control end of the single-pole double-throw switch 1037 is at a low level, the moving end P3 of the single-pole double-throw switch 1037 is connected to the first fixed end P1 of the single-pole double-throw switch 1037, the third switch 1035 is turned on, the power supply path from the power supply 104 to the front-end module 102 is turned on, and the power supply 104 supplies power to the front-end module 102.

After a period of time, the voltage difference across the resistor R2 returns to normal, and the differential voltage amplifier 1036 outputs a low level again, and the cycle continues.

[0073] The Wi-Fi chip 101 detects the level of the control end of the single-pole double-throw switch 1037 through the GPIO. When the Wi-Fi chip 101 detects that the level of the control end of the single-pole double-throw switch 1037 is at a high level for a number of times greater than a second number, the Wi-Fi chip 101 continuously outputs a high level through the GPIO, controls the active end P3 of the single-pole double-throw switch 1037 and the second fixed end P2 of the single-pole double-throw switch 1037 to be continuously turned on, and the third switch 1035 is continuously turned off.

When the Wi-Fi module 100 is powered on, the control end of the third switch 1035 is at a low level, and the third switch 1035 is turned on. When the front-end module 102 is normal, the voltage difference across the resistor R2 is normal, and the differential amplifier 1036 outputs a low level, keeping the moving end P3 of the single-pole double-throw switch 1037 and the first fixed end P1 of the single-pole double-throw switch 1037 connected. When the front-end module 102 is abnormal (for example, the front-end module is burned out, and the power supply end Vcc of the front-end module is short-circuited to the ground), the voltage difference across the resistor R2 increases, the differential amplifier 1036 outputs a high level, the moving end P3 of the single-pole double-throw switch 1037 is connected to the second fixed end P2 of the single-pole double-throw switch 1037, the control end of the third switch 1035 is at a high level, and the third switch 1035 is turned off.

[0084] The Wi-Fi chip 101 detects the level of the control end of the single-pole double-throw switch 1037 through the GPIO. When the Wi-Fi chip 101 detects that the level of the control end of the single-pole double-throw switch 1037 is at a high level for a number of times greater than a second number, the Wi-Fi chip 101 continuously outputs a high level through the GPIO, controls the active end P3 of the single-pole double-throw switch 1037 and the second fixed end P2 of the single-pole double-throw switch 1037 to be continuously turned on, and the third switch 1035 is continuously turned off.

[0085] In an embodiment of the present application, by detecting the level of the control end of the single-pole double-throw switch, when the level of the control end of the single-pole double-throw switch is high for multiple times, it indicates that the front-end module is damaged and cannot be recovered. At this time, the power supply path from the power supply to the front-end module is continuously disconnected, and the power supply no longer supplies power to the front-end module, thereby reducing misjudgment of the front-end module.

[0086] It should be noted that, in the embodiment of the present application, the third switch is turned on when its control terminal is at a low level, and is turned off when it is at a high level; the fourth switch is turned on when its control terminal is at a high level, and is turned off when it is at a low level.

Fig.11 In the embodiment, the detection module 103 includes a fifth switch 1040 , a sixth switch 1041 , a seventh switch 1042 and a differential amplifier 1043 .

[0089] The first end of the fifth switch 1040 is electrically connected to the power supply terminal Vcc of the front-end module 102 and the first input terminal of the differential amplifier 1043 respectively; the second end of the fifth switch 1040 is electrically connected to the control terminal of the fifth switch 1040, the first end of the sixth switch 1041, the first end of the seventh switch 1042 and the control end of the seventh switch 1042 respectively; the second end of the sixth switch 1041 is electrically connected to the power supply 104; the control end of the sixth switch 1041 is electrically connected to the output terminal of the differential amplifier 1043 and the GPIO3 included in the GPIO group corresponding to the detection module 103; the second end of the seventh switch 1042 is electrically connected to the second input terminal of the differential amplifier 1043.

[0090] When the Wi-Fi module 100 is powered on, the Wi-Fi chip 101 outputs a low level through GPIO3, and the sixth switch 1041 is turned on.

When the current flowing through the fifth switch 1040 is small, the differential amplifier 1043 outputs a low level, keeps the sixth switch 1041 turned on, and the front-end module 102 works normally. When the front-end module 102 is abnormal (for example, the front-end module is burned out, and the power supply terminal Vcc of the front-end module is short-circuited to the ground), the differential amplifier 1043 detects that the current flowing through the fifth switch 1040 is large, the differential amplifier 1043 outputs a high level, the sixth switch 1041 is disconnected, and then the fifth switch 1040 and the seventh switch 1042 are disconnected, the power supply path from the power supply 104 to the front-end module 102 is disconnected, and the power supply 104 no longer supplies power to the front-end module 102.

[0091] In the embodiment of the present application, by disconnecting the power supply path from the power supply to the front-end module where the abnormality occurs, it is possible to ensure that other front-end modules among the multiple front-end modules except the front-end module where the abnormality occurs operate normally.

[0095] When the Wi-Fi module 100 is powered on, the Wi-Fi chip 101 outputs a low level through GPIO4, and the sixth switch 1041 is turned on. After the sixth switch 1041 is turned on, the control end of the fifth switch 1040 and the control end of the seventh switch 1042 are high levels, the fifth switch 1040 and the seventh switch 1042 are turned on, and the front-end module 102 is powered on and works.

[0096] The differential amplifier 1043 samples the voltage across the fifth switch 1040, and calculates the current flowing through the fifth switch 1040 according to the voltage across the fifth switch 1040. When the current flowing through the fifth switch 1040 is small, the differential amplifier 1043 outputs a low level, keeps the sixth switch 1041 turned on, and the front-end module 102 works normally. When the front-end module 102 is abnormal (for example, the front-end module is burned out, and the power supply terminal Vcc of the front-end module is short-circuited to the ground), the differential amplifier 1043 detects that the current flowing through the fifth switch 1040 is large, the differential amplifier 1043 outputs a high level, the control end of the eighth switch 1044 is a high level, the eighth switch 1044 is turned on, the control end of the ninth switch 1045 and the control end of the sixth switch 1041 are high levels, the ninth switch 1045 is turned on, and the sixth switch 1041 is turned off.

After the fifth switch 1040 and the seventh switch 1042 are disconnected, the differential amplifier 1043 outputs a low level, the control end of the eighth switch 1044 is at a low level, and the eighth switch 1044 is disconnected; after the eighth switch 1044 is disconnected, the control end of the ninth switch 1045 and the control end of the sixth switch 1041 are at a low level, the ninth switch 1045 is disconnected, and the sixth switch 1041 is turned on; after the sixth switch 1041 is turned on, the control end of the fifth switch 1040 and the control end of the seventh switch 1042 are at a high level, the fifth switch 1040 and the seventh switch 1042 are turned on, and the front-end module 102 is powered on again, and the cycle continues.

[0097] The wireless fidelity chip 101 detects the level output by the differential amplifier 1043 through GPIO3. When the wireless fidelity chip 101 detects through GPIO3 that the differential amplifier 1043 outputs a high level for more than the third time, it indicates that the front-end module 102 is irreversibly damaged. At this time, the wireless fidelity chip 101 continuously outputs a high level through GPIO4, and the sixth switch 1041 is continuously disconnected, and the front-end module 102 is no longer powered.

[0098] In an embodiment of the present application, by detecting the level of the differential amplifier output, when the level of the differential amplifier output is high for multiple times, it indicates that the front-end module is damaged and cannot be recovered. At this time, the power supply path from the power supply to the front-end module is continuously disconnected, and the power supply no longer supplies power to the front-end module, thereby reducing misjudgment of the front-end module.

When the current flowing through the fifth switch 1040 is small, the differential amplifier 1043 outputs a low level, keeps the sixth switch 1041 turned on, and the front-end module 102 works normally. When the front-end module 102 is abnormal (for example, the front-end module is burned out, and the power supply terminal Vcc of the front-end module is short-circuited to the ground), the differential amplifier 1043 detects that the current flowing through the fifth switch 1040 is large, the differential amplifier 1043 outputs a high level, the sixth switch 1041 is disconnected, and then the fifth switch 1040 and the seventh switch 1042 are disconnected, the power supply path from the power supply 104 to the front-end module 102 is disconnected, and the power supply 104 no longer supplies power to the front-end module 102.

[0105] The first end of the fifth switch 1040 is electrically connected to the power supply terminal Vcc of the front-end module 102 and the first input end of the differential amplifier 1043 respectively; the second end of the fifth switch 1040 is electrically connected to the control end of the fifth switch 1040, the first end of the sixth switch 1041, the first end of the seventh switch 1042, the control end of the seventh switch 1042 and the first end of the third voltage stabilizing unit 1046 respectively; the second end of the sixth switch 1041 is electrically connected to the power supply 104; the second end of the seventh switch 1042 is electrically connected to the first end of the eighth switch 1044; the output end of the differential amplifier 1043 is electrically connected to the control end of the eighth switch 1044 and the GPIO3 included in the GPIO group corresponding to the detection module 103; the second end of the eighth switch 1044 is electrically connected to the first end of the ninth switch 1045, the control end of the ninth switch, the control end of the sixth switch and the GPIO4 included in the GPIO group; the second section of the third voltage stabilizing unit 1046 and the second end of the ninth switch 1045 are grounded.

[0106] When the Wi-Fi module 100 is powered on, the Wi-Fi chip 101 outputs a low level through GPIO4, and the sixth switch 1041 is turned on. After the sixth switch 1041 is turned on, the control end of the fifth switch 1040 and the control end of the seventh switch 1042 are high levels, the fifth switch 1040 and the seventh switch 1042 are turned on, and the front-end module 102 is powered on and works.

[0107] The differential amplifier 1043 samples the voltage across the fifth switch 1040, and calculates the current flowing through the fifth switch 1040 according to the voltage across the fifth switch 1040. When the current flowing through the fifth switch 1040 is small, the differential amplifier 1043 outputs a low level, keeps the sixth switch 1041 turned on, and the front-end module 102 works normally. When the front-end module 102 is abnormal (for example, the front-end module is burned out, and the power supply terminal Vcc of the front-end module is short-circuited to the ground), the differential amplifier 1043 detects that the current flowing through the fifth switch 1040 is large, the differential amplifier 1043 outputs a high level, the control end of the eighth switch 1044 is a high level, the eighth switch 1044 is turned on, the control end of the ninth switch 1045 and the control end of the sixth switch 1041 are high levels, the ninth switch 1045 is turned on, and the sixth switch 1041 is turned off. Then, the fifth switch 1040 and the seventh switch 1042 are turned off, the power supply path from the power supply 104 to the front-end module 102 is disconnected, and the power supply 104 no longer supplies power to the front-end module 102. After the fifth switch 1040 and the seventh switch 1042 are disconnected, the differential amplifier 1043 outputs a low level, the control end of the eighth switch 1044 is at a low level, and the eighth switch 1044 is disconnected; after the eighth switch 1044 is disconnected, the control end of the ninth switch 1045 and the control end of the sixth switch 1041 are at a low level, the ninth switch 1045 is disconnected, and the sixth switch 1041 is turned on; after the sixth switch 1041 is turned on, the control end of the fifth switch 1040 and the control end of the seventh switch 1042 are at a high level, the fifth switch 1040 and the seventh switch 1042 are turned on, and the front-end module 102 is powered on again, and the cycle continues.

[0108] The wireless fidelity chip 101 detects the level output by the differential amplifier 1043 through GPIO3. When the wireless fidelity chip 101 detects through GPIO3 that the differential amplifier 1043 outputs a high level for more than the third time, it indicates that the front-end module 102 is irreversibly damaged. At this time, the wireless fidelity chip 101 continuously outputs a high level through GPIO4, and the sixth switch 1041 is continuously disconnected, and the front-end module 102 is no longer powered.

[0109] In an embodiment of the present application, by detecting the level of the differential amplifier output, when the level of the differential amplifier is high for multiple times, it indicates that the front-end module is damaged and cannot be recovered. At this time, the power supply path from the power supply to the front-end module is continuously disconnected, and the power supply no longer supplies power to the front-end module, thereby reducing misjudgment of the front-end module.

[0110] It should be noted that, in this embodiment, the sixth switch is turned on when its control terminal is at a low level, and is turned off when it is at a high level; the fifth switch, the seventh switch, the eighth switch and the ninth switch are turned on when their respective control terminals are at a high level, and are turned off when they are at a low level.
