Problems solved by technology
[0002] In general, ordinary household plug-in boards simply indicate the maximum voltage, current or maximum power that the plug-in board can withstand. In some occasions, it is difficult to confirm whether the electrical appliances connected to the plug-in board will exceed the allowable capacity The maximum power limit, as a result, some high-power or super-high-power electrical appliances are often mistakenly connected, which will cause safety hazards such as burnt boards or even fires.

Embodiment Construction
[0007] The present invention will be described below in conjunction with the accompanying drawings and embodiments.
[0008] Such as figure 1 As shown, a novel plug-in board includes a plug-in board, a power measurement chip, a single-chip microcomputer, a liquid crystal display and a switch. A switch is connected to the plug-in board, and the switch is connected to the single-chip microcomputer, and the opening and closing of the switch is controlled by the single-chip microcomputer. There is also a power measurement chip connected with the switch, the power measurement chip is connected to a single-chip microcomputer, and connected to the commercial power, and the single-chip microcomputer is connected to a liquid crystal display.
[0009] Its working process is: connect a single-chip microcomputer-controllable switch between the mains and the plugboard, and then connect a power measurement chip in parallel with the mains. Once a useful appliance is connected to the plugboar...

The invention discloses a novel board plug. The novel board plug comprises a board plug body, a power measurement chip, a single chip microcomputer, a liquid crystal displayer and a switch. The switch is connected to the board plug body and further connected with the single chip microcomputer, on-off of the switch is controlled by the single chip microcomputer, the switch is also connected with the power measurement chip, the power measurement chip is connected with the single chip microcomputer and connected into a mains supply, and the single chip microcomputer is connected with the liquid crystal displayer. The novel board plug has the advantages that the liquid crystal displayer and the power measurement chip are arranged on the board plug body, therefore, power consumed by electric appliances plugged into the board plug body can be visually observed, and potential safety hazards caused by overload of the board plug body can be avoided.
Description
technical field [0001] The invention relates to a new type of inserting board. Background technique [0002] In general, ordinary household plug-in boards simply indicate the maximum voltage, current or maximum power that the plug-in board can withstand. In some occasions, it is difficult to confirm whether the electrical appliances connected to the plug-in board will exceed the allowable capacity The maximum power is limited, and as a result, some high-power or super-high-power electrical appliances are often mistakenly connected, which will cause safety hazards such as burnt boards or even fires. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a new type of plug board that can display the power used on the plug board. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a new type of plug-in board, including a plug-in board, a power measurement chip,...
