It will be appreciated that the rectifier circuit 16 is designed to supply the monitoring circuit 15 with direct current, so that the monitoring circuit 15 can continuously monitor the load information by supplying the direct current with a power supply circuit 11 disconnected. Meanwhile, the electric equipment can only keep working by the alternating current provided by the power supply circuit 11, so that the monitoring circuit 15 can supply power by direct current and can ensure that the electric equipment can inevitably stop working when monitoring load information. That is, the design of the rectifier circuit 16 and the monitor circuit 15 can effectively improve the monitor function and the energy saving function of the socket circuit 1.

It can be understood that, the transformer is arranged in the rectifying circuit 16, which can electrically isolate the power supply circuit 11 from the main control circuit 14, thereby effectively avoiding the direct connection between the high voltage in the power supply circuit 11 and the main control circuit 14, and further effectively protecting the main control circuit 14.

Optionally, the switching circuit 13 comprises a relay or a triac connected in series in the power supply circuit 11. It can be understood that the on-off of the alternating current in the power supply circuit 11 is controlled by the relay or the bidirectional thyristor, so that the problem that the physical switch is easy to generate the ignition phenomenon in the alternating current circuit can be effectively avoided, and the safety and the reliability of the socket circuit 1 are effectively ensured. Specifically, in the embodiment of the present invention, the switch circuit 13 includes a relay.

With continuing reference to fig. 2-6, further, the switch circuit 13 includes two switches, which are respectively connected in series to the live line and the neutral line of the power supply circuit 11.

Understandably, the switches are respectively connected in series on the live wire and the zero line, so that when the alternating current of the power supply circuit 11 is cut off, the live wire and the zero line can be both opened through the switches, and the alternating current in the commercial power can be effectively ensured to flow through the power supply circuit 11. That is, the design of the two switches can effectively ensure that the outlet circuit 1 can reliably disconnect the ac power supply in the outlet circuit 1 as required.

Specifically, in the embodiment of the present invention, the switch circuit 13 includes a relay K1, a relay K2, and a transistor Q1. The controlled loop of the relay K1 is connected in series with the live wire, the controlled loop of the relay K2 is connected in series with the zero wire, the first end of the control loop of the relay K1 and the first end of the control loop of the relay K2 are connected with the output end of the transformer at the same time, the second end of the control loop of the electric appliance K1 and the second end of the control loop of the relay K2 are connected with the collector of the triode Q1 at the same time, the base of the triode Q1 is connected with the main control circuit 14, and the emitter of the triode Q1 is connected with the digital ground. The main control circuit 14 can simultaneously control the on-off of the relay K1 and the relay K2 through the triode Q1, so that the function of simultaneously controlling the on-off of the live wire and the zero wire is realized.

Further, the monitoring circuit 15 includes a first relay, a second relay and a third relay, the first end of the first relay is connected with the output end of the rectifying circuit 16, the second end of the first relay is connected with the live wire of the power supply circuit 11, the first end of the second relay is connected with the zero wire of the power supply circuit 11, the second end of the second relay is grounded, the first end of the third relay is connected with the live wire, the second end of the third relay is connected with the main control circuit 14, and the control ends of the first relay, the second relay and the third relay are simultaneously connected with the main control circuit 14.

Understandably, the circuit design of the first relay, the second relay and the third relay enables the monitoring circuit 15 to form a direct current loop with the output end of the socket circuit 1 through the first relay and the second relay, and further enables the main control circuit 14 to judge load information according to the voltage level of the pin of the third relay, thereby ensuring that the socket circuit 1 can timely and automatically recover the alternating current power supply of the power supply circuit 11 under the condition of load access or load starting operation, and further ensuring the normal operation of the socket circuit 1.

Specifically, the monitoring circuit 15 further includes a triode Q2, the first relay is a relay K5, the second relay is a relay K3, and the third relay is a relay K4. The first end of the controlled loop of the relay K5 (namely the 3 rd pin of the relay K5 in FIG. 2) is connected with the output end of the transformer, and the second end of the controlled loop of the relay K5 (namely the 4 th pin of the relay K5 in FIG. 2) is connected with the output end of the live wire; a first end (namely a pin 3 of the relay K3 in the figure 2) of the controlled loop of the relay K3 is connected with the output end of the zero line, and a second end (namely a pin 4 of the relay K3 in the figure 2) of the controlled loop of the relay K3 is grounded; the first end of the controlled loop of the relay K4 (i.e., pin 3 of the relay K4 in fig. 2) is connected to the main control circuit 14, and the second end of the controlled loop of the relay K4 (i.e., pin 4 of the relay K4 in fig. 2) is connected to the live output. A first end of a control loop of the relay K5 (i.e., pin 1 of the relay K5 in fig. 2), a first end of a control loop of the relay K3 (i.e., pin 1 of the relay K3 in fig. 2), and a first end of a control loop of the relay K4 (i.e., pin 1 of the relay K4 in fig. 2) are simultaneously connected to an output terminal of the transformer, a second end of the control loop of the relay K5 (i.e., pin 2 of the relay K5 in fig. 2), a second end of the control loop of the relay K3 (i.e., pin 3 of the relay K3 in fig. 2), and a second end of the control loop of the relay K4 (i.e., pin 2 of the relay K4 in fig. 2) are simultaneously connected to a collector of the transistor Q2, a base of the transistor Q2 is connected to the main control circuit 14, and an emitter of the transistor Q2 is digitally connected.

It can be understood that the main control circuit 14 can simultaneously control the on/off of the relay K5, the relay K3 and the relay K4 through the triode Q2, so that when the detection circuit 12 detects that the load is in a low power consumption state such as shutdown or standby, the relay K5, the relay K3 and the relay K4 are controlled to be connected. The output terminals of the relay K5, the relay K3 and the power supply circuit 11 can form a dc loop together, and the main control circuit 14 can detect the voltage condition of the dc loop in real time through the relay K4, so as to monitor whether the load state changes. When the load maintains the low power consumption state, the voltage of the direct current loop is kept constant. When a new load is connected or the load is restarted and returns to the normal working state, the voltage of the direct current loop is pulled down. That is, the master control circuit 14 may monitor whether the load condition has changed by detecting whether the voltage at the first end of the control loop of the relay K4 is pulled low. If the load keeps the low power consumption state unchanged, the main control circuit 14 keeps the switch circuit 13 turned off and the monitoring circuit 15 connected; if the load recovers to the normal power consumption state, the main control circuit 14 controls the monitoring circuit 15 to be disconnected and the switch circuit 13 to be connected, so that the power supply circuit 11 can normally provide the load with the alternating current power.

In summary, the detection circuit 12 detects the power information such as the voltage, the current, and the power at the input end of the power supply circuit 11, and the main control circuit 14 determines the working state of the load electrically connected to the output end of the power supply circuit 11 according to the power information. When the load is in a normal power consumption state, the main control circuit 14 determines that the load is in a normal working state, and controls the power supply circuit 11 to keep a normal alternating current power supply state through the switch circuit 13, and meanwhile, the monitoring circuit 15 keeps an off state. When the load is in a low power consumption state, the main control circuit 14 determines that the load is in a low power consumption state such as shutdown or standby, and the main control circuit 14 controls the power supply circuit 11 to stop alternating current power supply through the switch circuit 13, and controls the monitoring circuit 15 to be connected so as to monitor whether the low power consumption state of the load changes. If the load returns to the normal power consumption state, the main control circuit 14 controls the power supply circuit 11 to return to the normal ac power supply through the switch circuit 13 again and cuts off the dc loop of the monitoring circuit 15.
