The above and other objects, features and advantages of the present invention will become more <RTIgt;

1 is a schematic diagram of an intelligent switching device in accordance with an embodiment of the present invention. 2 is a timing diagram of signals of an intelligent switching device according to an embodiment of the invention. In FIG. 1, the smart switching device 10 is adapted to be electrically connected between the power source 12 and the electronic device 14. In Fig. 2, reference numeral 201 denotes that the smart switching device 10 is turned on, and reference numeral 202 denotes that the smart switching device 10 is not turned on. Referring to FIG. 1 and FIG. 2 simultaneously, the smart switch device 10 mainly includes a solid state switch circuit 100, a current sensing circuit 110, a control circuit 120, a power supply module 130, and a manual switch 140. The control circuit 120 is electrically connected between the solid state switching circuit 100 and the current sensing circuit 110, and the power supply module 130 is electrically connected to the solid state switching circuit 100, the current sensing circuit 110, and the control circuit 120 to provide the required DC power supply. In addition, the control circuit 120 has a storage unit 120-1, a processing unit 120-2, and a timing unit 120-3. The storage unit 120-1 stores a preset current value to enable the processing unit 120-2 to read the preset current. The timer unit 120-3 is configured to set a preset time to cause the processing unit 120-2 to read the preset time.

In the present embodiment, the current sensing circuit 110 is configured to sense the amount of current flowing through the smart switching device 10 to generate a current sensing signal. The control circuit 120 is configured to control the solid state switching circuit 100 according to the current sensing signal. The control circuit 120 further determines whether the current sensing signal is greater than or equal to a preset current value, and determines whether the current sensing signal is less than a preset current value. When the control circuit 120 determines that the current sensing signal is greater than or equal to the preset current value, the control circuit 120 enters the power-on mode, and controls the solid-state switching circuit 100 to remain in an on state, so that the power source 12 is electrically connected to the electronic device 14. That is to say, in the first time t1 and the second time t2, the smart switching device 10 remains conductive 201, and at this time, the AC power source 1 _{in the} power source 12 is provided by the control operation of the smart switching device 10 in the power-on mode. 100% of the AC power source I _{in is in the} electronic device 14.

When the control circuit 120 determines that the current sensing signal is less than the preset current value, the control circuit 120 enters the standby mode, and controls the solid state switching circuit 100 to remain in the conducting state at the first time t1, so that the power source 12 is energized in the first time t1. The electronic device 14 is connected to the electronic device 14 and the solid state switching circuit 100 is controlled to remain in a non-conducting state during the second time t2, so that the power source 12 cannot be electrically connected to the electronic device 14 during the second time 12. That is, the first time t1, the intelligent switching unit 10 remains turned on 201, then the AC power source 12 is I _in will be provided to the electronic device 14. In the second time t2, the smart switching device 10 remains non-conductive 202, and the AC power source I _{in the} power source 12 is not supplied to the electronic device 14 at this time. If the first time t1 is set to 0.1 second and the second time t2 is set to 0.9 seconds, the AC power source I _{in the} power source 12 is only 10% provided by the control operation of the smart switching device 10 in the standby mode. The AC power source I _{in is in the} electronic device 14. Therefore, when the electronic device 14 is in the standby state, the AC power source I _out outputted by the smart switching device 10 _leaves only the electric energy as shown in FIG. 2.

As can be seen from the above description, the smart switch device 10 provides less power to the electronic device in the standby mode than the power supplied to the electronic device in the power-on mode, thereby saving power.

In some embodiments, when the smart switching device 10 is in the standby mode, the control circuit 120 further determines whether the time of the standby mode exceeds a preset time. When the time of determining the standby mode exceeds the preset time, the control circuit 120 enters the shutdown mode. The solid state switching circuit 100 is controlled to remain in a non-conducting state, so that the power source 12 cannot be electrically connected to the electronic device 14. That is to say, the AC power source I _{in of the} power source 12 is controlled by the intelligent switching device 10 in the shutdown mode, and no AC power source I _{in is} supplied to the electronic device 14. Therefore, the smart switching device 10 will be more power-saving than in the standby mode when the smart switching device 10 is in the standby mode.

In addition, after the manual switch 140 of the smart switch device 10 is activated, the control circuit 120 returns from the power-off mode to the power-on mode, and controls the solid-state switch circuit 100 to remain in an on state, so that the power source 12 is electrically connected to the electronic device 14 . . At this time, the AC power source 1 _{in the} power source 12 provides a 100% AC power source I _in to the electronic device 14 by the control operation of the smart switching device 10 in the power-on mode.

Although in the above embodiment, the control circuit 120 has the storage unit 120-1 and the timing unit 120-3 for respectively storing the preset current value and the preset time, which is not intended to limit the present invention, and is generally known in the art. When it is known that the processing unit 120-2 of the control circuit 120 itself has a storage space (not shown), the storage space can be directly used to store the preset current value and the preset time, so that the storage unit 120-1 can be used. It is omitted from the timing unit 120-3.

Through the description of the above embodiments, some basic operational steps of the intelligent switching device of the present invention can be summarized, as shown in FIGS. 3A and 3B. 3A and FIG. 3B are flowcharts illustrating a method of operating an intelligent switching device according to an embodiment of the present invention, the smart switching device being adapted to be electrically connected between a power source and an electronic device. Referring to FIG. 3A and FIG. 3B, the operation method includes the following steps: First, sensing the amount of current flowing through the smart switching device to generate a current sensing signal (step S301). Then, the solid state switching circuit is controlled according to the current sensing signal, and it is determined whether the current sensing signal is greater than or equal to the preset current value, and it is determined whether the current sensing signal is less than the preset current value (step S303). When judging the current sensing signal When it is greater than or equal to the preset current value, it enters the power-on mode, and controls the solid-state switching circuit to maintain the conductive state, so that the power source is electrically connected to the electronic device (step S305). When it is determined that the current sensing signal is less than the preset current value, the system enters the standby mode, and controls the solid state switching circuit to remain in the conductive state for the first time, so that the power source is electrically connected to the electronic device in the first time (step S307). ). In addition, in the standby mode, the solid state switching circuit is further controlled to remain non-conductive for the second time, so that the power source cannot be electrically connected to the electronic device in the second time (step S309). In addition, in the standby mode, it is further determined whether the time of the standby mode exceeds the preset time (step S311). When it is determined that the standby mode time exceeds the preset time, the shutdown mode is entered, and the solid state switching circuit is controlled to remain non-conductive, so that the power source cannot be electrically connected to the electronic device (step S313).

In summary, in the smart switch device of the present invention, the different switch states of the solid state switch circuit are respectively controlled by the power on mode, the standby mode or the power off mode in which the control circuit is located, so the smart switch device can easily adjust the power supply. Providing power to the electronic device is therefore more energy efficient.
