Description of the invention: [Technical field to which the invention pertains] The invention has a general sequence. The invention relates to a busbar system, in particular to a series of busbars of a busbar n. [Prior Art] With the reliance of users on electronic products, peripheral electronic devices are becoming more and more diversified. Therefore, many electronic products have begun to be equipped with more than one connection port to simultaneously connect a plurality of electronic devices. At present, the most widely used (four) connection interface is the serial bus (Unwersai SerialBus; USB). However, in addition to the electronic processing of the central processing of the N architecture, you can directly configure multiple connection bees to use the other 'use other architectures. Some electronic products of RSIC and Epic, if you want to configure multiple USB connections 4', will touch the USB hub n between the USB port and the electronic product as a bridge. Please refer to the H-picture system for the knowledge technology with the Cong hub (4) System Schematic®. The USB system 1GG is electrically connected to the power supply terminal 2〇0 'USB system', and the system 100 includes a plurality of USB ports and a hub 12, and the USB ports are electrically connected to the power supply terminal 200, USB. The hub 12 is electrically connected to the power supply terminal for operating - the second working power P2' and is communicatively coupled to the USB port 埠Ha and 1; when the 201128380 electronic device 300 is plugged into the USB port 埠na, the electronic device is connected The first working power is extracted from the power supply terminal 200, and the USB hub can transmit the data signal si through the USB port 蟑lla and the electronic device 3. It can be clearly found that whether the electronic device 300 is plugged into the USB port 埠lla, the USB hub π will draw the second working power P2 from the power supply terminal 2, which will cause waste of power, especially when Small electronic products, such as mobile phones or notebook computers, have limited internal power, and the battery power of the battery is small, and the USB hub 12 usually has to use a second working power P2 greater than 100 mA, which causes battery power. Consumption is too fast and the use time of electronic products is reduced. SUMMARY OF THE INVENTION Accordingly, it is a primary object of the present invention to provide a universal serial bus (USB) system having a universal serial bus line, which detects the presence or absence of current from a power source. The supply end flows to the electronic device to control the power opening and closing of the USB hub, so that when the electronic device is plugged into the USB port, the power of the USB hub is turned on, and the power of the USB hub is turned off when no electronic device is plugged into the USB port. . The technical means for solving the problem of the present invention: a universal serial bus (USB) system, 201128380 is electrically connected to the power supply end of the electronic product, and the serial bus system includes a USB hub, a power control switch, a plurality of brain connections and a plurality of current units; the power control relationship is electrically connected between the power supply terminal and the (10) hub; the coffee connection system is separately connected to the USBm; the current_unit is divided into two groups. Set up electricity / Shenglian,,. Between the power supply end and the connection port, the current detection is connected to the power control switch as early as possible. Shi: The Zhongwei Electronic Farming Plug-in is connected to any of the above-mentioned Qinglian devices. The dry electronic device draws the first power from the power supply terminal, and the current detection unit (10) corresponding to the inserted port is sent. Turning on the marriage '" enables the power pin __, and makes the brain line benefit from the power supply terminal to draw the second power. In a preferred embodiment of the present invention, when the USB port is removed, the power = Plug in to the power control switch. A "early read stop" sends a power-on signal to the power gate in the embodiment, when the power (four) switch does not receive power on (4) (d). The invention compares the effects of the prior art: The sequence _ _ bus system can open the r.si 201128380 USB hub when the universal sequence with I wh U is plugged into the USB port, J does not When the electronic device is plugged into the USB port, the USB 隼 green crying power is turned off, so that the general-purpose serial bus system can be saved, so that the use time of the electronic product is more uniform than when the electronic device is not connected.
