The present invention relates to a power management device, and more particularly to a distributed power management device.

In computer systems, users often use external electronic devices, such as mouse and keyboard, or electronic devices such as network cameras and IP phones. However, many electronic devices are not easy to install power when installed. The technology has developed Power over Ethernet (PoE). The POE technology transmits data to the external electronic device while transmitting data through the data transmission line.

However, in the POE environment, the conventional technique is to set the power communication port for connecting the external electronic device to the same motherboard, and to supply the power communication power with the same power module.

However, the computer device 100 using the prior art has several obvious disadvantages, since a plurality of power supply ports 113 are disposed on the motherboard 11, and the power supply port 113 is used to supply the power P0, especially when When the external electronic device has a network power supply function, a large working power P0 is required. Therefore, the power module 111 needs to be a large wattage power supply, and thus the host board 11 is likely to cause poor heat dissipation. In addition, since the space of the motherboard 11 is limited, the number of power supply ports 113 that can be set is also greatly limited, and the user cannot provide a large number of external electronic devices.

When the control processing unit sends the first data signal, the first data signal and the first power system are transmitted to the first power supply communication port via the first switch; when the control processing unit passes the second data signal to the first switch, the first When the interface 埠 and the second interface 埠 are transmitted to the second power communication port, the second power system is transmitted to the second power communication port.

In a preferred embodiment of the present invention, the expansion board further includes a second switch, the second switch-on relationship is electrically connected to the second power module and the second interface, to receive and transmit the second data signal and the second Two electric power.

In another preferred embodiment of the present invention, the motherboard and the expansion board respectively have a transmission address, and the first data signal and the second data signal respectively include address data, so that the first switch determines the first The transmission path of the data signal and the second data signal.

Compared with the conventional computer equipment, the distributed power management device of the present invention distributes the power supply communication device on the motherboard and the expansion board with the power module, and performs data calculation by the control processing unit on the motherboard. Processing and sending, therefore, each power module is a smaller wattage power supply than the power module in the prior art, and can enable the distributed power management device to have better heat dissipation effect and simultaneously supply power. The number of communication ports will not be affected by the space of the motherboard. It is also possible to increase the number of power communication ports by adding expansion boards.
