In an embodiment of the present invention, the low power consumption module 11 is a low power consumption MCU (Microcontroller Unit), and specifically, the low power consumption MCU may be a single chip microcomputer of various types as long as the working principle within the protection range provided by the embodiment of the present invention can be implemented. The low-power consumption MCU mainly runs in a low-power consumption state during starting and running so as to reduce the power consumption of the chip switching circuit, and meanwhile, the low-power consumption MCU needs smaller starting voltage so as to be well started under lower voltage.

In an embodiment of the present invention, the control module 12 may be any one or more of a communication module, an intelligent module and other control MCU, wherein the control module 12 requires a power consumption module 11 with low power consumption to operate normally and a start voltage to start. In this embodiment, the control module 12 is specifically a communication module for implementing data communication with an external control device, and it is understood that in other embodiments of the present invention, the control module 12 may also be other modules, which are set according to actual use requirements, and are not limited herein.

The communication module comprises a ZIGBEE module, a Bluetooth module, an NB-IoT module (Narrow Band Internet of Things), a LoRa module (Long Range Radio Long-distance Radio) and the like. And the control module 12 processes information with higher power consumption during operation, and realizes functions such as networking communication with the outside.

In an embodiment of the present invention, the power-taking control module 14 is respectively connected to the on-state power-taking circuit and the off-state power-taking circuit, and specifically, the power-taking control module 14 is configured to correspondingly control connection states of the on-state power-taking circuit and the off-state power-taking circuit according to the power-taking control signal output by the low power consumption module 11 or the control module 12, so as to implement on-state power-taking or off-state power-taking. Therefore, the power-taking control signal can be an off-state signal or an on-state signal. Specifically, in this embodiment, the power-taking control module 14 may be a relay, and when the relay acquires the power-taking control signal of the on-state signal, the relay is closed, and at this time, the relay is connected to the on-state power-taking circuit, so that on-state power taking is realized; when the power-taking control signal of the off-state signal is acquired, the relay is disconnected, and the off-state power-taking circuit is connected to the relay, so that off-state power taking is realized. It is understood that in other embodiments of the present invention, the power take-off control module 14 may also be a switching device such as a thyristor or a transistor, which is set according to actual use requirements, and is not limited herein.

In an embodiment of the present invention, the power supply terminal of the low power consumption module 11 is connected to the external power supply 20, so that when the chip switching circuit is connected to the external power supply 20 to implement power-on, the power supply terminal of the low power consumption module 11 can receive power supplied by the external power supply 20 to implement start-up operation. Specifically, in the present embodiment, the power supply 20 is configured to provide 3V power, and it should be understood that in other embodiments of the present invention, the power supply 20 may also provide 3.3V, 5V and other power supplies required for the low power consumption module 11 and the control module 12 to operate normally.

Further, in an embodiment of the present invention, the control end of the low power consumption module 11 is connected to the first on-off module 13, and at this time, the control end of the low power consumption module 11 may output a first control signal to the first on-off module 13, so that the first on-off module 13 controls the operating state of the control module 12 according to the first control signal feedback, specifically, the first control signal may be an on signal or an off signal. When the low power consumption module 11 outputs a first control signal, specifically, a shutdown signal, to the first on-off module 13, the first on-off module 13 controls the control module 12 to be in an off state. When the low power consumption module 11 outputs a first control signal, specifically, a conduction signal, to the first on-off module 13, the first on-off module 13 controls the control module 12 to be in a working state.

Fig. 5 to 9 show specific implementation circuits in an embodiment of the invention, wherein the low power module 11 may be a first chip U1 in the drawing, the control module 12 may be a second chip U2 in the drawing, the first switching module 13 may be a first fet Q1 in the drawing, and a control terminal of the low power module 11 may be an RC6 pin in the first chip U1 in the drawing.

When the power-on module works specifically, the chip switching circuit is powered on and is communicated with an external power supply 20 to realize power-on, and at the moment, the low-power-consumption module 11 needs small voltage energy for starting, so that the power-on module can well start to work and operates in a low-power-consumption state; at this time, the low power consumption module 11 outputs a first control signal, specifically, a shutdown signal, to the first on-off module 13, so that the first on-off module 13 controls the control module 12 to stop working.

Further, when the control module 12 needs to perform work control, the low power consumption module 11 outputs a power-taking control signal, which is specifically an off-state signal, to the power-taking control module 14, so that the power-taking control module 14 performs off-state power taking, and at this time, the power-taking state in the off state can provide higher energy required by the control module 12 when being started, thereby avoiding the problem that the power required by the control module cannot be provided when the power is taken in the on state, which causes uninterrupted start and reset under the power-taking in the on state, and the product cannot take power. Further, the low power consumption module 11 outputs a first control signal, specifically, a conduction signal, to the first on-off module 13, so that the first on-off module 13 controls the control module 12 to operate, and the operation of the control module 12 is realized.

Further, after the control module 12 finishes working, the low power consumption module 11 may further output a first control signal, which is a shutdown signal, to the first on-off module 13, so that the first on-off module 13 controls the control module 12 to stop working.

In the embodiment of the invention, due to the arrangement that the power supply end of the low-power-consumption module is connected with an external power supply, when the chip switching circuit is communicated with the power supply to be powered on to work, the low-power-consumption module can be started to work and runs at low power consumption; simultaneously because the low-power consumption module that sets up, control module, first break-make module, and get electric control module, make after low-power consumption module work, accessible output control signal is to first break-make module in order to realize the control to control module, at this moment when control module needs during operation, low-power consumption module controls drive control module earlier and carries out the off-state and get the electricity, make can provide the required higher energy when control module starts under the off-state gets the electric state, furthermore, low-power consumption module is through controlling first break-make module, make control module carry out start-up work under the off-state gets the electric state. The low-power-consumption module that only starts required low voltage when making to power on, through low-power-consumption module work in order to reduce standby power consumption when using at ordinary times, when control module needs work, get the electricity control module through low-power-consumption module control earlier and realize off-state and get the electricity, in order to provide required energy when control module starts, it carries out work to start control module again, make the current start-up that directly starts control module and bring when having avoided power on reset incessantly, the problem that the product can not get the electricity, the problem that the success rate is low on having solved current circuit, the consumption is big.

Example two

Fig. 2 is a schematic block diagram of a chip switching circuit according to a second embodiment of the present invention, which has a structure substantially the same as that of the first embodiment, except that in this embodiment, the low power module 11 is in communication connection with the control module 12 for transmitting a communication signal between the low power module 11 and the control module 12.

Specifically, the low power module 11 and the control module 12 are correspondingly provided with a first communication end, and the first communication end of the low power module 11 is connected with the first communication end of the control module 12, so that the low power module 11 is switched from a sleep state to a working state according to an interrupt signal output by the first communication end of the control module 12.

Specifically, in an embodiment of the present invention, after the chip switching circuit is powered on, the low power module 11 starts to operate in a low power consumption state, and when the control module 12 needs to operate, the low power module 11 outputs a power-taking control signal, specifically an off-state signal, so that the power-taking control module 14 performs off-state power taking.

Further, the low power consumption module 11 outputs a first control signal, specifically, a conduction signal, to the first on-off module 13, so that the first on-off module 13 controls the control module 12 to be in a working state. Meanwhile, the low power consumption module 11 starts to switch from a normal operating state to a sleep state, and continuously outputs the first control signal to the first on-off module 13 in the sleep state, so that the control module 12 continuously operates, and the low power consumption module 11 is in an ultra-low power consumption standby state.

At this time, the control module 12 is always in the working state, and when the control module 12 finishes working and needs to stop working, it needs to wake up the low power consumption module 11, so that the low power consumption module 11 is switched from the sleep state to the working state again, and is switched to the low power consumption module 11 to work. Therefore, the control module 12 outputs the interrupt signal to the low power module 11 through the first communication terminal, so that the low power module 11 wakes up according to the interrupt signal output by the control module 12, and after the low power module 11 wakes up according to the external interrupt, the low power module 11 outputs the first control signal, which is specifically the turn-off signal, to the first on-off module 13, so that the first on-off module 13 controls the control module 12 to stop working.

It should be noted that, when the chip switching circuit is controlled to switch from the low power consumption module 11 to the control module 12 for operation, when a power failure occurs suddenly and the power failure is recovered after a period of time, there may be a voltage drop at this time, but the low power consumption module 11 is still in a sleep state, and at this time, the control module 12 may have a problem that power cannot be obtained when restarting.

Fig. 5 to 9 show specific implementation circuits in the embodiment of the invention, wherein the first communication terminal of the low power module 11 may be RB6 of a first chip U1 in the figure, and the first communication terminal of the control module 12 may be PB13 pin of a second chip U2 in the figure.

In the embodiment of the invention, after the low-power-consumption module controls the first on-off module to enable the control module to work, the low-power-consumption module controls the control module to be switched from the working state to the dormant state, so that only the control module works and the low-power-consumption module sleeps at the moment, the power consumption can be further reduced, and when the control module finishes working and needs to be switched back to the low-power-consumption module to work, the control module outputs an interrupt signal to the low-power-consumption module through the first communication terminal, so that the low-power-consumption module is interrupted and awakened, the subsequent low-power-consumption module controls the control module to stop working, and the working state between the low-power-consumption module and the control module is conveniently switched to reduce.

EXAMPLE III

Referring to fig. 3, a module diagram of a chip switching circuit according to a third embodiment of the present invention is shown, where the structure of the chip switching circuit according to the third embodiment of the present invention is substantially the same as that of the second embodiment, and the difference is that in this embodiment, the chip switching circuit further includes a second on/off module 15;

the second on-off module 15 is connected between the power supply 20 and the low power consumption module 11, and the second on-off module 15 is further connected with the control module 12 and is used for controlling the working state of the low power consumption module 11 in a feedback manner under the control of the control module 12.

The first on-off module 13 is further configured to control the operating state of the control module 12 under the control of the control module 12. Further, in an embodiment of the present invention, a first control end of the control module 12 is connected to the first on-off module 13, and is configured to control a working state of the first on-off module 13; the second control end of the control module 12 is connected to the second on-off module 15, and is configured to control the operating state of the second on-off module 15.

Further, in an embodiment of the present invention, when the chip switching circuit is powered on, since the control module 12 is not powered on, the control on the second on-off module 15 cannot be realized, when the control module does not output a signal to control the second on-off module, the second on-off module 15 is in an on state, and therefore the low power consumption module 11 starts to start operation, when the control module 12 needs to operate, the low power consumption module 11 outputs a power-taking control signal, which is specifically an off-state signal, so that the power-taking control module 14 takes power in an off state, further, the low power consumption module 11 outputs a first control signal, which is specifically an on-state signal, to the first on-off module 13, so that the first on-off module 13 controls the control module 12 to be in an operating state, and the low power consumption module 11 controls the control module 12 to start operation. At this time, the control module 12 continuously outputs a second control signal, which is a conduction signal, to the first on-off module 13, so that the first on-off module 13 controls the control module 12 to be in a working state, and the control module 12 controls the self state.

Further, the control module 12 outputs a third control signal, specifically, a turn-off signal, to the second turn-off module 15, so that the second turn-off module 15 is turned off to control the low power module 11 to be in an inoperative state, and the control module 12 drives the low power module 11 to stop working, so that the working switching between the low power module 11 and the control module 12 is completed.

Further, when the control module 12 finishes the operation and needs to stop and switch to the low power consumption module 11, the control module 12 outputs a third control signal, which is a conducting signal, to the second switching-off module 15, so that the second switching-off module 15 controls the low power consumption module 11 to be in the operating state. Meanwhile, the low power consumption module 11 starts to continuously output a first control signal, specifically, a turn-off signal, to the first on-off module 13, so that the first on-off module 13 controls the control module 12 to be in an off state, thereby completing the work switching between the control module 12 and the low power consumption module 11. This in turn makes it possible to alternately realize the operation switching between the low power consumption module 11 and the control module 12.

The circuit for implementing the embodiment of the present invention may be as shown in fig. 7 and fig. 9, wherein the second switching-off module 15 may be a second fet Q2; the first control terminal PF1 of the control module 12 may be a PF1 pin of the second chip U2 in the figure, and is configured to output a second control signal to the first on-off module 13; the second control terminal of the control module 12 may be a pin PF2 in the second chip U2 in the figure, and is used for outputting a third control signal to the second on/off module 15.

In the embodiment of the invention, after the low-power-consumption module controls the first on-off module to enable the control module to work, the control module controls the working state of the control module by controlling the first on-off module and controls the second on-off module to enable the control module to stop working, and when the control module finishes working and needs to switch back to the low-power-consumption module to work, the control module drives the low-power-consumption module to start working by controlling the second on-off module, and the low-power-consumption module drives the control module to stop working by controlling the first on-off module, so that the working switching between the low-power-consumption module and the control module can be realized in turn, and therefore, when the control module does not need to work, the control module is switched to start the low-power-consumption module to reduce power consumption; when the control module needs to be started to work, the low-power-consumption module controls the switching control module to work.

The key switch can be a mechanical key or a touch key.

Specifically, in an embodiment of the present invention, the display module 17 may specifically be a light emitting diode, and performs corresponding display according to the current power-taking state controlled by the power-taking control module 14, specifically, for example, when the switching module 16 controls the chip switching circuit to be switched from the low power consumption module 11 to the control module 12 for operation, the low power consumption module 11 controls the power-taking control module 14 first, so that the power-taking control module 14 performs power-taking in an off state, and at this time, the display module 17 performs corresponding display according to the current power-taking state in an off state. When the display module 17 is in the on-state power-taking state, the display is stopped.

Further, in an embodiment of the present invention, when the chip switching circuit is powered on, the low power module 11 starts to operate in a low power consumption state, and when a user switches between the low power module 11 and the control module 12 through the switching module 16, the low power module 11 acquires a switching signal input by the switching module 16, and at this time, the low power module 11 outputs a power taking control signal, specifically an off-state signal, so that the power taking control module 14 takes off-state power; meanwhile, the low power consumption module 11 outputs a signal to the display module 17 in an off-state power-taking state, so that the display module 17 displays the signal;

further, the low power consumption module 11 outputs a first control signal, which is specifically a conduction signal, to the first on-off module 13, so that the first on-off module 13 controls the control module 12 to be in a working state, and the low power consumption module 11 drives the control module 12 to start. At this time, the control module 12 outputs a second control signal, which is specifically a conduction signal, to the first on-off module 13, so that the first on-off module 13 controls the control module 12 to be in a working state, and the control module 12 realizes control of the self state.

Further, the first signal output end of the low power consumption module 11 and the first signal output end of the control module 12 each include a RELAY start end (RELAY1 ON, RELAY2 ON) and a RELAY OFF end (RELAY1 OFF, RELAY2 OFF), and when the low power consumption module 11 or the control module 12 outputs a control signal to the RELAY through the RELAY start ends, the RELAY is correspondingly turned ON, so that the single-live-wire switch is in an ON-state power-taking state; when the low power consumption module 11 or the control module 12 outputs a control signal to the relay through the relay off end, the relay is correspondingly disconnected, so that the single live wire switch is in an off state to get power. In this embodiment, the number of the first signal output ends is two, it can be understood that in other embodiments of the present invention, the number of the first signal output ends may also be other, and the number is set according to actual use requirements, which is not limited herein. Further, diodes are respectively connected between the first signal output end of the low power consumption module 11 and the first signal output end of the control module 12 and the power taking control module 14, and the diodes are used for avoiding the problem of circuit conduction between the first signal output ends.

Further, the chip switching circuit further includes a protection resistor R11 connected between the power supply 20 and the reset terminal MCLR/VPP/RA3 of the low power module 11, and a first capacitor C1 and a second capacitor C2 connected to both ends of the protection resistor R11, wherein one end of the first capacitor C1 is connected to the end of the power supply 20 connected to the protection resistor R11, the other end of the first capacitor C1 is grounded, one end of the second capacitor C2 is connected to the end of the protection resistor R11 connected to the reset end MCLR/VPP/RA3 of the low power module 11, the other end of the second capacitor C2 is grounded, wherein the reset end MCLR/VPP/RA3 of the low power module 11 needs high level power supply, therefore, by arranging a protection resistor R11 between the power supply terminal VDD and the reset terminal MCLR/VPP/RA3 of the low power module 11, to provide for normal operation of the reset MCLR/VPP/RA3 of the low power module 11.

When the power module 11 is powered on, the control end RC6 of the low power module 11 is in an input high-impedance state, so that the control end RC6 of the low power module 11 is connected to the power supply 20 due to the connection of the second resistor R2, so that the control end RC6 of the low power module 11 is pulled up, and therefore the gate voltage and the source voltage of the first fet Q1 are the same, so that the first fet Q1 is not turned on, and thus the first fet Q1 does not work, that is, the control module 12 is in a stop working state at this time.

Further, when the low power module 11 is activated and needs to drive the control module 12 to be deactivated, the control terminal RC6 can be driven to output a high level. When the low power consumption module 11 needs to control the operation of the control module 12, the relay is correspondingly turned off when the low power consumption module 11 outputs a control signal to the relay through the relay off end, so that the single live wire switch is in an off state to get power. Furthermore, the low power consumption module 11 outputs a low level through the control terminal RC6, so that the gate voltage of the first fet Q1 is smaller than the source voltage, and thus the first fet Q1 is turned on to operate, and at this time, the power supply terminal VDD of the control module 12 is connected to the power supply 20, so that the control module 12 performs a start operation in an off state.

Further, when the control module 12 finishes its operation and the low power module 11 needs to control the control module 12 to stop operating, the low power module 11 outputs a high level through its control terminal RC6, so that the gate voltage of the first fet Q1 is equal to the source voltage, and thus the first fet Q1 is turned off to stop operating, so that the control module 12 stops operating.

On the basis of the above steps, after the low power consumption module 11 drives the control module 12 to start up in the off-state power-taking state, the low power consumption module 11 is switched from the normal operating state to the sleep state, and continuously outputs the low level to the first on-off module 13 through the control terminal RC6 in the sleep state, so that the control module 12 continuously operates, and the low power consumption module 11 is in the ultra-low power consumption standby state.

Further, when the control module 12 finishes working and needs to stop working, it needs to wake up the low power module 11, so that the low power module 11 is switched to the working state again from the sleep state, at this time, the control module 12 outputs an interrupt signal to the low power module 11 through the first communication terminal PB13, so that the low power module 11 wakes up according to the interrupt signal output by the control module 12, and after the low power module 11 wakes up according to an external interrupt, the low power module 11 continuously outputs a high level to the first on-off module 13 through the control terminal RC6, so that the first on-off module 13 is in an off state, so as to control the control module 12 to stop working.

EXAMPLE six

Please refer to fig. 6, which is a schematic circuit structure diagram of a chip switching circuit according to a sixth embodiment of the present invention, the structure of the chip switching circuit according to the sixth embodiment of the present invention is substantially the same as that of the fifth embodiment, and the difference is that the first on-off module 13 is further configured to control the operating state of the control module 12 under the control of the control module 12; the first control end PF1 of the control module 12 is connected to the first on-off module 13, and is configured to control a working state of the first on-off module 13; the second control terminal PF2 of the control module 12 is connected to the second on-off module 15 and is used for controlling the operating state of the second on-off module 15.

Further, the first switching module 13 includes an NMOS transistor, a first end of the first switching module 13 is connected to the control end RC6 of the low power consumption module 11 and the first control end PF1 of the control module 12, a second end of the first switching module 13 is connected to the power supply end VDD of the control module 12, and a third end of the first switching module 13 is connected to the power supply 20.

Specifically, the first switching module 13 includes a first fet Q1, a third resistor R3 connected to the gate of the first fet Q1, a first diode D1, and a second diode D2. The grid of the first field effect transistor Q1 is respectively connected with one end of the third resistor R3, the negative electrodes of the first diode D1 and the second diode D2, the other end of the third resistor R3 is grounded, the positive electrode of the first diode D1 is connected with the control end RC6 of the low power consumption module 11, and the positive electrode of the second diode D2 is connected with the first control end PF1 of the control module 12; the drain of the first fet Q1 is connected to the power supply 20, and the source of the first fet Q1 is connected to the supply terminal VDD of the control module 12. Wherein, the first field effect transistor Q1 is an NMOS transistor. The first diode D1 and the second diode D2 are used to prevent a circuit from flowing between the control terminal RC6 of the low power module 11 and the first control terminal PF1 of the control module 12. It should be noted that, in practical use, the resistance of the third resistor R3 may be set to be larger, for example, megaohms, and then, by the design of the large resistor of the third resistor R3, the power consumption of the low power consumption module 11 during the output control may be reduced.

In the fifth embodiment, the specific structure of the chip switching circuit can be implemented by referring to the fifth embodiment, and when the chip switching circuit is powered on and is communicated with the external power supply 20 to implement power-on,

in this embodiment, the specific work flow is substantially the same as that of the fifth embodiment, and the difference is that when the control terminal RC6 of the low power consumption module 11 and the first control terminal PF1 of the control module 12 output a low level, the gate voltage of the first on-off module 13 is equal to the source voltage, so that the first on-off module 13 is controlled to be turned off and not operated, and the control module 12 is in an off state. In turn, when the control terminal RC6 of the low power module 11 and the first control terminal PF1 of the control module 12 output a high level, the control module 12 is in an operating state.

Therefore, when the chip switching circuit is connected to the external power supply 20 to achieve power-on, the control module 12 does not start to operate, at this time, the first control terminal PF1 of the control module 12 is in an input high-impedance state, at this time, the first control terminal PF1 of the control module 12 does not output a high level, and at the same time, the control terminal RC6 of the low power consumption module 11 outputs a low level, so that the first on-off module 13 is controlled to be turned off and not operated, and therefore the control module is in an off state.

Further, after the low power consumption module 11 is switched to the control module 12 to operate, the first control end PF1 of the control module 12 continuously outputs a high level to control the operation of itself. At this time, other control flows are substantially the same as those in the fifth embodiment, and are not described herein.

Further, in an embodiment of the present invention, as shown in fig. 7, the chip switching circuit further includes a second switching-off module 15;

Further, a first end of the second on-off module 15 is connected to the second control end PF2 of the control module 12, a second end of the second on-off module 15 is connected to the power supply end VDD of the control module 12, and a third end of the second on-off module 15 is connected to the power supply 20.

When the chip switching circuit is communicated with an external power supply 20 to realize power-on, because the low-power module 11 and the control module 12 do not start to work, at this time, the control end RC6 of the low-power module 11 and the first control end PF1 and the second control end PF2 of the control module 12 are both in an input high-impedance state, at this time, the second control end PF2 of the control module 12 does not output a high level, and the gate voltage of the second on-off module 15 is smaller than the source voltage, so that the second on-off module 15 is controlled to be switched on and work; meanwhile, since the control terminal RC6 of the low power module 11 and the second control terminal PF2 of the control module 12 do not output a high level, the gate voltage of the first on-off module 13 is equal to the source voltage, so that the first on-off module 13 is controlled to be turned off and not operated.

At the moment, a power supply 20 of the low-power module is communicated with a power supply end VDD of the low-power module 11 after passing through the second switching-off module 15, so that the low-power module 11 is normally powered, and at the moment, because the starting voltage required by starting the low-power module 11 is small, the low-power module 11 can drive the low-power module 11 to start to work no matter the single-live-wire switch is in an on-state power taking state or an off-state power taking state; meanwhile, the first on-off module 13 is turned off, so that the power supply 20 cannot be connected to the power supply terminal VDD of the control module 12, and the control module 12 is in an off state.

Further, when the low power module 11 needs to drive the control module 12 to be inoperative, the low power module 11 can drive the control terminal RC6 to output a low level all the time.

Further, when the low power module 11 needs to be switched to the control module 12, and the low power module 11 outputs a control signal to the relay through the relay off terminal, the relay is correspondingly turned off, so that the single live wire switch is in an off state to obtain power. Furthermore, the low power consumption module 11 outputs a high level through the control terminal RC6, so that the gate voltage of the first on/off module 13 is greater than the source voltage, and thus the first on/off module 13 is turned on to operate, and at this time, the power supply terminal VDD of the control module 12 is connected to the power supply 20, so that the control module 12 performs the start operation in the off state power-taking state.

Further, the control module 12 continuously outputs a high level to the first on-off module 13 through the first control end PF1, so that the control module 12 controls its own state to keep its normal operation. Further, the control module 12 outputs a high level to the second on-off module 15 through the second control terminal PF2, so as to control the second on-off module 15 to be turned off and not work, at this time, the power supply 20 cannot be communicated with the power supply terminal VDD of the low power module 11, so that the low power module 11 stops working, and thus, the switching of the working state between the low power module 11 and the control module 12 is realized.

Further, when the control module 12 finishes the operation and needs to be switched to the low power consumption module 11, the control module 12 outputs a low level to the second on-off module 15 through the second control terminal PF2 to control the second on-off module 15 to be turned on and operated, so that the low power consumption module 11 starts to operate, and meanwhile, the control module 12 outputs a low level to the first on-off module 13 through the first control terminal PF1 or the low power consumption module 11 outputs a low level to the first on-off module 13 through the control terminal RC6 to control the first on-off module 13 to be turned off and not operated, so that the control module 12 stops operating, thereby realizing the switching of the operating state between the control module 12 and the low power consumption module 11.

Further, in this embodiment, the flow of the switching control performed by the switching module 16 and the status display performed by the display module 17 corresponds to the fifth embodiment, and the specific implementation can refer to the above embodiments, which is not described herein.

It should be noted that, in this embodiment, when the switching module 16 performs switching control, it is configured to respectively control the operating states of the control module 12 and the low power consumption module 11 through the first switching module 13 and the second switching module 15, and at this time, when the low power consumption module 11 is switched to the control module 12 to operate, it outputs a third control signal, specifically a turn-off signal, to the second switching module 15 through the second control terminal PF2 of the control module 12, so that the control stops the operation of the low power consumption module 11, instead of the flow described in the fifth embodiment.

Meanwhile, in this embodiment, information communication between the first communication terminal and the second communication terminal of the low power module 11 and the control module 12 may also be performed, so that when the operation between the low power module 11 and the control module 12 is switched, any one of the low power module 11 and the control module 12 is always started, and the other one is correspondingly controlled to enter the sleep state.

Example eight

An eighth embodiment of the present invention further provides a chip switching circuit, and a structure of the chip switching circuit provided in the eighth embodiment of the present invention is substantially the same as that of the foregoing embodiments, except that in this embodiment, the number of the control modules 12 may also be multiple, specifically, for example, the control module 12 may include any one or more of the foregoing intelligent module, control MCU, and ZIGBEE module, bluetooth module, NB-IoT module (Narrow Band of Internet of Things) and Long Range Radio remote Radio in the communication module.

The corresponding number of the first on-off modules 13 is arranged according to the number of the control modules 12, and each first on-off module 13 is connected with the corresponding control module 12, so that when the chip switching circuit is powered on, the low-power module 11 works first, and the low-power module 11 realizes the switching work of any control module 12 by controlling the on-off state of the first on-off module 13 connected with any control module 12.

It can be understood that, in the embodiment of the present invention, the low power consumption module 11, the control module 12, the first on-off module 13, and the second on-off module 15 in the chip switching circuit may also be integrated on one chip to implement the circuit function provided in the embodiment of the present invention.

Example nine

A ninth embodiment of the present invention further provides a single live wire switch, which includes the chip switching circuit described in any one of the first to eighth embodiments. In the embodiment, when the single live wire switch is powered on, no matter the single live wire switch is in an on-state power taking state or an off-state power taking state, the chip switching circuit controls to start only the low power consumption module 11 first, so that the power consumption can be reduced, meanwhile, the starting success rate of the single live wire switch connected with a low-power load can be improved due to the lower voltage required by the low power consumption module 11 when starting, meanwhile, when the control module 12 needs to work, the low-power module 11 firstly controls the power generation control module 14 to carry out off-state power generation, so that the power consumption required for starting the control module 12 can be provided in the off state, and further, the low power consumption module 11 controls the switching to the starting of the control module 12, therefore, the problem that the control module 12 and the low-power load cannot be started successfully due to the fact that the energy required by the control module 12 is high when the single live wire switch is powered on is effectively solved. Meanwhile, the low-power-consumption module 11 is used under a normal standby state, and the control module 12 is switched to work when the control module 12 is required to work, so that the power consumption of the single-live-wire switch during working can be effectively reduced.

Example ten

The tenth embodiment of the present invention further provides a switch device, as shown in fig. 10, the switch device includes the nine main single live wire switches 100 and the nine slave single live wire switches 200, where each of the main single live wire switches 100 and the slave single live wire switches 200 includes the chip switching circuit according to any one of the first to eighth embodiments.

Further, in an embodiment of the present invention, a live end of the master single live wire switch 100 is connected to a live end of the slave single live wire switch 200, a load terminal a of the master single live wire switch 100 is connected to one end of the load 300, the other end of the load 300 is connected to a neutral end N of alternating current, a live end L of the slave single live wire switch 200 is connected to a live end L of alternating current, and a power supply communication end S of the master single live wire switch 100 is connected to a power supply communication end S of the slave live wire switch 200. It should be noted that, in the embodiment, the number of the slave single live wire switches 200 is one, and the slave single live wire switches 200 and the master single live wire switch 100 are combined into a single live wire double-control switch device. It is understood that in other embodiments of the present invention, the number of the slave single-live wire switches 200 may be other, and they are all connected to the master single-live wire switch 100, and they are set according to the actual use requirement, and are not limited herein.

Further, in an embodiment of the present invention, after the main single live wire switch 100 is powered on, the low power consumption module 11 in the main single live wire switch 100 operates, and the slave single live wire switch 200 provides power for the slave single live wire switch 200 during operation through connection of the live wire end L and the communication end S respectively corresponding to the main single live wire switch 100, so that the low power consumption module 11 in the slave single live wire switch 200 is driven to operate, and further, the power supply communication end S can also perform signal communication with the slave single live wire switch 200.

Further, the main single live wire switch 100 operates through any one of the on-state power taking circuit and the off-state power taking circuit, so that on-state power taking or off-state power taking is achieved, when the main single live wire switch 100 needs to be switched to the control module 12 from the low power consumption module 11 to operate, the chip switching circuit in the main single live wire switch 100 firstly controls the power taking control module 14 to perform off-state power taking, and then controls the low power consumption module 11 to be switched to the control module 12 to operate in the off-state power taking state.

Further, the slave single-line switch 200 is connected with the live wire end L and the communication end S corresponding to the master single-live wire switch 100 respectively, so that after power taking is realized, when the master single-live wire switch 100 is in an on-state power taking state, the slave single-live wire switch 200 is also in the on-state power taking state; when the master single hot switch 100 is in the off state to take power, the slave single hot switch 200 is also in the off state to take power. Therefore, at this time, the main single live wire switch 100 is controlled to perform off-state power taking, and after the low-power-consumption module 11 switches to the control module 12, the single live wire switch 200 delays for a preset time and then correspondingly switches the control module 12 to operate in the off-state power taking state, or when the single live wire switch 200 receives a control signal sent by the power supply communication terminal S after the control module 12 in the main single live wire switch 100 operates, the chip switching circuit in the single live wire switch 200 controls the low-power-consumption module 11 to switch to the control module 12 to operate in the off-state power taking state. Therefore, the control module 12 in the main single live wire switch 100 and the control module 12 in the slave single live wire switch 200 are staggered at intervals to switch the starting time, the problem that the power taking electric quantity cannot meet the working electric quantity requirement and the power taking is unsuccessful when the single live wire switch is started at the same time is solved, and the starting success rate is improved.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
