[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] The embodiment of the present invention discloses an intelligent switch on-off device, see Figure 1 As shown, it includes: a sampling interface 1, a sampling signal processing circuit 2, a wireless control circuit 3, a load control circuit 4, a wireless and relay transfer interface 5, a power supply circuit 6, a relay 7 and a wireless module 8;

[0038] The sampling port of the sampling interface 1 is used to connect to the output end of the mechanical switch; the wireless transfer end of the wireless and relay transfer interface 5 is connected to the wireless module 8, the input end of the relay 7 is connected to the external live wire, the output end of the relay 7 is used to connect to the input end of the load, and the control end of the relay 7 is connected to the output end of the load control circuit 4;

[0039] The sampling port of the sampling interface 1 is connected to the input end of the sampling signal processing circuit 2, the output end of the sampling signal processing circuit 2 is connected to the sampling signal input end of the wireless control circuit 3, the wireless control end of the wireless control circuit 3 is connected to the wireless transfer end of the wireless and relay transfer interface 5, the input end of the load control circuit 4 is connected to the wireless control signal output end of the wireless and relay transfer interface 5, the output end of the load control circuit 4 is connected to the relay 7 transfer end of the wireless and relay transfer interface 5, and the power supply circuit 6 is connected to the external live wire through the sampling interface 1.

[0040] Specifically, one end of the mechanical switch is connected to the live wire and the other end is connected to the sampling interface 1. When the mechanical switch is opened and closed, the voltage at the output end of the mechanical switch will change. For example, when the mechanical switch is closed from open, the sampling interface 1 will receive the output end of the mechanical switch from low level to high level. When the mechanical switch is opened from closed, the sampling interface 1 will receive the output end of the mechanical switch from high level to low level. The sampling interface 1 will transmit the level change to the sampling signal processing circuit 2. The sampling signal processing circuit 2 outputs the processed sampling signal to the wireless control circuit 3 according to the high level or low level. The wireless control circuit 3 sends the control signal to the wireless and relay transfer interface 5 through the wireless control end according to the sampling signal. The wireless and relay transfer interface 5 sends the control signal of the wireless control circuit 3 to the load control circuit 4 through the wireless control signal output end. The load control circuit 4 sends the control signal to the control end of the relay 7 through the output end according to the control signal, so that the relay 7 is actuated, the state of the current load is changed, and the load is powered on or off.

[0041] Specifically, after receiving the control command sent by the user terminal, the wireless module 8 will send the control command to the wireless control circuit 3 through the wireless transfer end of the wireless and relay transfer interface 5. The wireless control circuit 3 will generate a control signal according to the control command. The wireless control circuit 3 will then use the wireless control end to send the control signal to the wireless and relay transfer interface 5. The wireless and relay transfer interface 5 will send the control signal of the wireless control circuit 3 to the load control circuit 4 through the wireless control signal output end. The load control circuit 4 sends the control signal to the control end of the relay 7 through the output end according to the control signal, so that the relay 7 is activated, the state of the current load is changed, and the load is powered on or off.

[0042] Specifically, the input end of relay 7 is connected to the external live wire, the output end of relay 7 is connected to the load, and relay 7 is connected in series with the load. When relay 7 is closed, the load is energized, and when relay 7 is disconnected, the load loses power. By isolating the mechanical switch from the load and using the mechanical switch as a signal trigger device, the remote wireless intelligent control and the mechanical switch both control whether the load is energized by controlling the action of relay 7, thereby achieving the effect of the mechanical switch and the intelligent switch working independently of each other without interfering with each other.

[0043] It can be understood that the mechanical switch no longer has a fixed switch position. For example, the closing of the mechanical switch does not mean that the load will be energized, but it is determined by the current working state of relay 7. Regardless of whether the mechanical switch is closed or opened, the trigger signal changes, and relay 7 changes its working state accordingly. If relay 7 is currently in a closed state, then after the mechanical switch is actuated, relay 7 will be disconnected, and the load will lose power and be closed. If relay 7 is currently in an open state, then after the mechanical switch is actuated, relay 7 will be closed, and the load will be energized and turned on. The same is true for wireless intelligent control. The signals of the mechanical switch and the wireless control no longer distinguish between the on signal and the off signal, but serve as a trigger signal for changing the current working state of relay 7, so that the signals of the two switches are unified, and the effect of non-interference between the two switches is achieved.

[0044] It can be seen that the sampling signal of the embodiment of the present invention samples the signal output from the output end of the mechanical switch, and outputs the sampling signal to the wireless controller according to the action change of the mechanical switch. The wireless module 8 receives the control command sent by the user through the user terminal, and sends it to the wireless controller through the wireless and relay adapter interface 5. The wireless control can generate a control signal for the sampling signal and the control command, and output it to the load control circuit 4. The load control circuit 4 controls the relay 7, and the two control methods are integrated into a trigger signal. The final relay 7 controls the switch of the load, and the two control methods are combined into one, realizing independent control of the intelligent switch and the mechanical switch. The user can control the load according to the intelligent switch or the mechanical switch under any circumstances, thereby improving the user experience.
