When the active terminal c0 of the spdt switch 100 is connected to the first conducting terminal c1 thereof, that is, the target conducting terminal is the first conducting terminal c1 of the spdt switch 100, the switch position detecting unit 22 may send a first switch position signal to the main control unit 23, where the first switch position signal is used to indicate that the active terminal c0 of the spdt switch 100 is currently connected to the first conducting terminal c1 thereof; when the active terminal c0 of the spdt switch 100 is connected to the second conducting terminal c2 thereof, i.e., the target conducting terminal is the second conducting terminal c2 of the spdt switch 100, the switch position detecting unit 22 may send a second switch position signal to the main control unit 23, where the second switch position signal is used to indicate that the active terminal c0 of the spdt switch 100 is currently connected to the second conducting terminal c2 thereof.

Specifically, the main control unit 23 is connected to the on-off state detection unit 21 and the switch position detection unit 22, and the main control unit 23 may receive the switch control signal and generate an on-off control signal for controlling the target power supply path according to the on-off state signal, the switch position signal, and the switch control signal; the target power supply path is a power supply path where the target conducting terminal of the single-pole double-throw switch 100 is located.

Wherein, the on-off control signal is used for indicating the on-off control unit 24 to switch on the target power supply path; the off control signal is used to instruct the on-off control unit 24 to cut off the target power supply path.

Specifically, the voltage-stabilizing subunit 252 is connected to the ac-to-dc subunit 251, and the voltage-stabilizing subunit 252 is configured to convert the preset dc signal into a target dc signal required by the operations of the on-off state detecting unit 21, the switch position detecting unit 22, the main control unit 23, and the on-off control unit 24

The voltage of the target dc electrical signal is VCC, and the magnitude of VCC can be determined according to actual requirements, which is not limited here.

Since the ac-to-dc subunit 251 outputs the preset dc signal to the voltage regulator subunit 252 when the power supply paths between the live wire of the utility power and the load 300 are all cut off, the voltage regulator subunit 252 can normally supply power to the above units when the power supply paths between the live wire of the utility power and the load 300 are all cut off.

In a specific application, the relay 242 may be a magnetic latching relay, which only consumes power at the instant of being turned on or off, thereby reducing power consumption.

Referring to fig. 4, fig. 4 is a schematic circuit diagram of a single-live-wire intelligent switch according to an embodiment of the present disclosure. As shown in fig. 4, in the present embodiment, the on-off state detection unit 21 includes: the circuit comprises a first switch tube Q1, a second switch tube Q2, a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, an operational amplifier U1, a fifth resistor R5, a first diode D1, a zener diode D2, a sixth resistor R6, a seventh resistor R7, a first capacitor C1 and a second capacitor C2. Wherein:

a first conducting end of the first switching tube Q1 is connected with a live wire of a mains supply, a common junction point of a second conducting end of the first switching tube Q1 and a first end of the fifth resistor R5 is connected with a control end D0 of the on-off control unit 24, a second end of the fifth resistor R5 is connected with an anode of the first diode D1, a common junction point of a cathode of the first diode D1, a power supply end of the operational amplifier U1, a cathode of the voltage-stabilizing diode D2 and a first end of the first capacitor C1 is connected with an input end of the voltage-stabilizing subunit 252, a second end of the first capacitor C1 is grounded, an anode of the voltage-stabilizing diode D2, a first end of the second capacitor C2, a first end of the sixth resistor R6 and a positive input end of the operational amplifier U1 are connected in common, a second end of the second capacitor C2 and a second end of the sixth resistor R6 are grounded, a first end of the seventh resistor R7 is connected with an output end of the voltage-stabilizing subunit 252, and a first end of the seventh resistor R7 is connected with an output end of the voltage-stabilizing subunit 252, The first end of the fourth resistor R4 and the negative input end of the operational amplifier U1 are connected in common, the output end of the operational amplifier U1, the second end of the first resistor R1, the first end of the second resistor R2 and the first end of the third resistor R3 are connected in common, the first end of the first resistor R1 is connected to the controlled end of the first switch tube Q1, the second end of the second resistor R2 is connected to the controlled end of the second switch tube Q2, the common point of the first conducting end of the second switch tube Q2 and the second end of the fourth resistor R4 is connected to the main control unit 23, and the second conducting end of the second switch tube Q2, the second end of the third resistor R3 and the ground end of the operational amplifier U1 are all grounded.

In this embodiment, the live line of the utility power is grounded. When any power supply path between the hot line of the utility power and the load 300 is switched on, an alternating current signal 51 as shown in fig. 5 (a) is present on the power supply path.

Near the zero point of the positive half cycle of the ac signal 51, since the voltage of the first end of the first capacitor C1 is lower at this time and cannot reach the regulated voltage of the zener diode D2, at this time, the ac signal 51 cannot charge the second capacitor C2, so that the voltage of the positive input end of the operational amplifier U1 is smaller than the voltage of the negative input end thereof, at this time, the operational amplifier U1 outputs a low-level signal (the voltage is 0 v), the second switch Q2 is not conductive, and the first conductive end of the second switch Q2 outputs a high-level signal to the main control unit 23.

As the voltage of the ac power signal 51 increases, the voltage of the first end of the first capacitor C1 increases, when the voltage of the first end of the first capacitor C1 reaches the regulated voltage of the zener diode D2, the ac power signal 51 starts to charge the second capacitor C2, when the voltage of the positive input end of the operational amplifier U1 is greater than the voltage of the negative input end thereof, the operational amplifier U1 outputs a high level signal, at this time, the second switch Q2 is turned on, the first turn-on end of the second switch Q2 outputs a low level signal to the main control unit 23, at this time, the first switch Q1 is also turned on, and due to the energy storage function of the first capacitor C1, the first capacitor C1 may output a preset dc power signal to the zener subunit 252 through the first end thereof.

Meanwhile, as the second capacitor C2 continuously discharges through the sixth resistor R6, the voltage of the first end of the second capacitor C2 continuously decreases, and when the voltage of the first end of the second capacitor C2 is smaller than the voltage to ground of the fourth resistor R4, the voltage of the positive input end of the operational amplifier U1 is smaller than the voltage of the negative input end thereof, at this time, the operational amplifier U1 outputs a low level signal, the first switch tube Q1 and the second switch tube Q2 are both non-conductive, and the first conductive end of the second switch tube Q2 outputs a high level signal to the main control unit 23.

Based on this, when any one of the power supply paths between the live line of the utility power and the load 300 is turned on, the waveform of the voltage at the first end of the second capacitor C2 is as shown at 52 in (a) of fig. 5, and the first conducting end of the second switch Q2 outputs the pulse signal 53 as shown at (a) of fig. 5 to the main control unit 23.

When all power supply paths between the live wire of the commercial power and the load 300 are disconnected, the on-off state detection unit 21 continuously outputs a low level signal (with a voltage of 0 v) to the main control unit 23, or it can be considered that the on-off state detection unit 21 does not output a pulse signal.

In still another embodiment of the present application, the switch position detection unit includes: an eighth resistor R8, a ninth resistor R9, a tenth resistor R10, a third switch tube Q3, an eleventh resistor R11, a twelfth resistor R12, a thirteenth resistor R13 and a fourth switch tube Q4. Wherein:

a first end of the eighth resistor R8 is a first input end of the switch position detecting unit 22, a second end of the eighth resistor R8, a first end of the ninth resistor R9 and a controlled end of the third switching tube Q3 are connected in common, a second end of the ninth resistor R9 and a second conducting end of the third switching tube Q3 are both grounded, a first conducting end of the third switching tube Q3 and a second end of the tenth resistor R10 are connected in common to serve as a first output end of the switch position detecting unit 22, and a first end of the tenth resistor R10 is connected with an output end of the regulator subunit 252; a first end of the eleventh resistor R11 is a second input end of the switch position detecting unit 22, a second end of the eleventh resistor R11, a first end of the twelfth resistor R12, and a controlled end of the fourth switch tube Q4 are commonly connected, a second end of the twelfth resistor R12 and a second end of the fourth switch tube Q4 are both grounded, a first end of the fourth switch tube Q4 and a second end of the thirteenth resistor R13 are commonly connected as a second output end of the switch position detecting unit 22, and a first end of the thirteenth resistor R13 is connected to an output end of the voltage stabilizing subunit 252. The first output terminal and the second output terminal of the switch position detection unit 22 are both connected to the main control unit 23.

In this embodiment, when a power supply path between the live wire of the utility power and the load 300 is connected, an ac signal 51 as shown in (a) or (b) in fig. 5 exists on the power supply path, and an electrical signal is input to the switch position detecting unit 22 at the beginning of a positive half cycle of the ac signal 51, and due to the conduction characteristics of the third switch tube Q3 and the fourth switch tube Q4 in the switch position detecting unit 22, a glitch 54 recognizable by the main control unit 23 as shown in (b) in fig. 5 is output to the main control unit 23 at the first output terminal (i.e., the second terminal of the tenth resistor R10) or the second output terminal (i.e., the second terminal of the thirteenth resistor R13) of the switch position detecting unit 22. The specific output of the short-time pulse signal from which output terminal of the switch position detection unit 22 is output is related to the target conducting terminal to which the active terminal of the single-pole double-throw switch 100 is currently connected. Specifically, when the active terminal of the single-pole double-throw switch 100 is currently connected to the first pass terminal c1, that is, the power supply path where the first pass terminal c1 is located is turned on, the first output terminal of the switch position detection unit 22 outputs a short-time pulse signal to the main control unit 23, and the second output terminal of the switch position detection unit 22 continuously outputs a high-level signal to the main control unit 23, or it can be considered that the second output terminal of the switch position detection unit 22 does not output a signal. The waveform of the electrical signal currently output from the second output terminal of the switch position detection unit 22 during the entire period of the alternating current electrical signal 51 may be as shown at 55 in (b) of fig. 5. When the active end of the single-pole double-throw switch 100 is currently connected to the second pass end c2, that is, the power supply path where the second pass end c2 is located is turned on, the second output end of the switch position detection unit 22 outputs a short-time pulse signal to the main control unit 23, and the first output end of the switch position detection unit 22 continuously outputs a high-level signal to the main control unit 23, or it can be considered that the first output end of the switch position detection unit 22 has no signal output. The waveform of the electrical signal currently output from the first output terminal of the switch position detection unit 22 during the entire period of the alternating current electrical signal 51 may be as shown at 55 in (b) of fig. 5.

When the power supply paths between the live wire of the utility power and the load 300 are all cut off, and the active terminal of the single-pole double-throw switch 100 is currently connected to the first conducting terminal c1 thereof, the first output terminal of the switch position detection unit 22 outputs a pulse signal as shown by 56 in (c) of fig. 5, and the second output terminal of the switch position detection unit 22 continuously outputs a high-level signal, or it can be considered that the second output terminal of the switch position detection unit 22 has no signal output; when the power supply path between the live wire of the utility power and the load 300 is cut off and the active terminal of the single-pole double-throw switch 100 is currently connected to the second conducting terminal c2 thereof, the second output terminal of the switch position detection unit 22 outputs a pulse signal as shown by 56 in (c) of fig. 5, and the first output terminal of the switch position detection unit 22 continuously outputs a high-level signal, or the first output terminal of the switch position detection unit 22 can be regarded as having no signal output.

Based on this, the main control unit 23 can determine the on/off states of the power supply paths between the live wire of the utility power and the load 300 and the target conducting terminal of the single-pole double-throw switch 100 according to the signal S1 output by the on/off state detection unit 21, the signal S2 output by the first output terminal of the switch position detection unit 22, and the signal S3 output by the second output terminal of the switch position detection unit 22.

By way of example and not limitation, the correspondence between the signal S1, the signal S2, and the signal S3 and the on-off state of the power path and the target on terminal of the single pole double throw switch 100 may be as shown in table 1.
