In one embodiment, as shown in fig. 2A and 2D, the intelligent power supply system 2000 further includes a power converter 60 for receiving ac power from an external power source and converting the ac power into power Vcc (e.g., dc power 12V, 5V, 3.3V, 1.8V, etc.) for supplying the controller 50. Referring to fig. 2A, the power converter 60 is disposed in the intelligent power supply system 2000 on the same side of the female socket 20 to provide the power Vcc required by the female socket 20. The external power source may have different specifications depending on countries or applications, such as 90V to 264V AC power supply.

In one embodiment, each of the female sockets includes a display element (not shown), and when the female socket is in a conductive state, the display element is turned on; when the female seat is in a conductive state, the display assembly turns off the lamp. Thus, the user can observe whether the display component is on or not, and know whether the female seat is in the conducting state or not. In one embodiment, the manual switch 30 includes an indicator light (not shown) for confirming the conductive state of the female socket.

Referring to fig. 2A, in an embodiment of the present application, the network signal received by the network signal transceiver 40 may include a wireless network signal or a wired network signal.

The wired network signal includes BACnet, LonWorks, M-bus, Modbus, DALI, EnOcean, RS485, RS232, KNX, Power over Ethernet (Power over Ethernet) signal, or Power Line Communication (Power Line Communication) network signal.

Referring to fig. 3, the present application further provides an intelligent power supply circuit 3000 for controlling the power-on state between an external power source Pext and a female socket 20, the intelligent power supply circuit 3000 includes: press signal receiving terminals T30, T32 for receiving press signals S30, S32 from the manual switch 30; a network signal receiver 40 for receiving a network signal; and a controller 50 for controlling the power-on state between the female socket 20 and the external power Pext according to at least one of the pressing signals S30, S32 and the network signal. When the power-on state of the female socket 20 is controlled according to the pressing signals S30, S32, the controller 50 controls the power-on state of the female socket 20 according to at least one pressing frequency or at least one pressing time length included in the pressing signals S30, S32.

Referring to fig. 3, in an embodiment, the controller 50 is further electrically connected to at least one output sensor, each output sensor is electrically connected to the mother sockets 20, and the controller 50 controls and detects the output current, the output voltage, or the output power of each mother socket according to the ac current sensing value output by each mother socket. In addition, in one embodiment, the pressing signal sensor connected to the pressing signal receiving terminals T30, T32 includes a switch coupled between the power Vcc and the ground, and can determine whether there is a pressing signal by sensing whether the power Vcc and the ground are turned on.

In an embodiment of the present application, the controller 50 can control the power-on state of the female socket 20 according to the number of pressing times included in the pressing signal. Referring to fig. 4A, the controller 50 switches the energization/deenergization of the sockets 20, 21 according to the number of times of pressing, the controller 50 does not energize/energize the sockets 20, 21 at the next pressing, and the result of each pressing is to switch the previous energization/deenergization state.

In another embodiment of the present invention, the at least one pressing time is an odd number or an even number within a limited time, and the limited time is counted by the controller 50 after receiving the first pressing signal. For example, the controller 50 energizes the female sockets 20, 21 when the pressing times are accumulated to an odd number (e.g., three, five, etc.), and the controller 50 does not energize the female sockets 20, 21 when the pressing times are accumulated to an even number (e.g., two, four, etc.). Alternatively, the controller 50 energizes the sockets 20, 21 when the cumulative number of pressing times is an even number of times, and the controller 50 does not energize the sockets 20, 21 when the cumulative number of pressing signals is an odd number of times. After the limited time, the controller 50 receives the next pressing signal and recalculates the next limited time and the number of pressing within the limited time. This technique has the advantage of avoiding improper actuation of the female housing 20, 21 due to erroneous pressing. The pressing method is used to control the power-on or power-off of the mother sockets 20, 21, which is executed according to the predetermined action to achieve the desired effect, but the pressing can generate the control effect. Thus, the improper operation of the female seats 20 and 21 caused by improper operation of children or the old can be avoided.

However, the number of female sockets according to the present invention is not limited to two, and may be one, three, or other numbers, depending on the requirements.

According to the present application, the operation manner of the manual switch 30 and the female sockets 20 and 21 is not limited to that shown in fig. 4A. FIG. 4B shows another embodiment of the operation of the manual switch 30 and the female housing 20, 21. For example, when at least one of the female sockets 20 and 21 is not energized, both the female sockets 20 and 21 are energized after the manual switch 30 is pressed once. When both the female sockets 20 and 21 are energized, both the female sockets 20 and 21 are not energized after the manual switch 30 is pressed once.

Referring to fig. 5A, an embodiment is shown in which the number of manual switches and female sockets is different from that of fig. 4A. In fig. 5A, the controller 50 can control the power-on state of the female housing 20 according to the number of pressing times included in the pressing signals generated by the two manual switches 30 and 31. Referring to fig. 5A, when at least one of the manual switches 30 and 31 is pressed once, the controller 50 switches the power on/off of the female socket 20 according to the pressing, the controller 50 does not power on/off the female socket 20 when the next pressing is performed, and the power on/off state of the previous pressing is switched as a result of each pressing. As a result, please refer to FIG. 5B.

In one embodiment, although the manual switch and the female housing are shown in FIGS. 4A, 4B, 5A, and 5B as being separate, such pressing operation can also be applied to embodiments in which the manual switch and the female housing are adjacent.

In one embodiment, the pressing time period may include a first pressing time period or a second pressing time period, and the first pressing time period is longer than the second pressing time period. The first and second pressing time periods can be determined as required, for example, the first pressing time period is three, four seconds or other longer time period, and the second pressing time period is one second or other shorter time period. Wherein the controller controls the power-on state of the female base according to the number of times of the first pressing time length, the number of times of the second pressing time length, or the number of times of the first pressing time length and the second pressing time length contained in the pressing signal. For simplicity, the time lengths of the first and second subsequent pressing are referred to as long pressing and short pressing, respectively.

Referring to fig. 6, the controller 50 controls the energization/deenergization of the female sockets 20, 21 according to the long press and the short press generated by the manual switch 30. Among them, the long press and the short press generated by the manual switch 30 and the corresponding power on/off of the female sockets 20, 21 are shown in fig. 6.

Referring to fig. 7, an embodiment is shown in which the number of manual switches and female sockets is different from that of fig. 6. In fig. 7, the controller 50 controls the power-on state of the female socket 20 according to the long and short pressing of the two manual switches 30 and 31. Referring to fig. 7, when one of the manual switches 30 and 31 generates a long press and a short press, the controller 50 energizes the female socket 20 according to the press. When at least one of the manual switches 30 and 31 generates a short press twice, the controller 50 does not energize the female socket 20 according to the press. The pressing action is not limited to a predetermined one of the manual switches 30 and 31, but may be any one of the manual switches; or the former one is one of the manual switches and the next one is the other. In this way, the controller 50 can control the energization/deenergization of the female socket 20 according to the long press and the short press.

In the above embodiments, for example, FIGS. 4A, 4B, 5A, 5B, 6, 7 are the power-on/power-off operations generated according to a pressing signal priority mode included in the controller. When the controller is in the pressing signal priority mode, the controller controls the power-on state of at least one female socket according to the pressing signal. In addition, the controller also includes a network signal priority mode and a push and network signal equalization mode.

When the controller is in the network signal priority mode, as shown in fig. 8 and 9, the controller 50 controls the power on/off of the mother socket (20, fig. 8) or (20, 21, fig. 9) according to the network signal. Wherein, whether each mother socket is powered on or not can determine the definition of network signal according to the requirement.

In addition, referring to fig. 10, when the controller is in the pressing and network signal equalization mode, when the signal is received, the determination signal is the pressing signal or the network signal. When the pressing signal is sent, the controller controls the conduction or non-conduction of the female seat according to the pressing signal. When the network signal is received, the controller controls the mother socket to be conductive or non-conductive according to the network signal. In the pressing and network signal equalization mode, the pressing signal and the network signal can be used synchronously to control the conduction or non-conduction of the mother seat.

The term "in one embodiment" or the like is used repeatedly. This phrase generally does not refer to the same embodiment; it may also refer to the same embodiment. The terms "comprising," "having," and "including" are synonymous, unless the context dictates otherwise.

Although the present application has been described with reference to specific embodiments, it should be understood that the present application is not limited to the above embodiments, and those skilled in the art can make various changes and modifications without departing from the scope of the present application, and it should be understood that the present application can also be implemented with various modifications and equivalents of the above embodiments.
