Embodiment Construction

[0017] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown, this embodiment provides an electronic control device for automatic shutdown, which includes a power supply circuit and a switching circuit. The power supply circuit can be a power supply circuit of any line in the electric control device. When the power supply circuit is connected, the electric control device can work, and when the power supply circuit is disconnected, the electric control device cannot work. Wherein, the electronic control device can be a large-scale device, or a handheld terminal, such as a mobile phone, a tablet computer, an e-book reader, an audio player or a video player, etc.; or, the electronic control device is a computer; preferably, It is a laptop computer.

[0019] Such as figure 1 As shown, the power supply circuit 100 is provided with one or more interruption pa...

Abstract

The invention discloses an automatic shutting electric control device which comprises a power supply circuit and a switching circuit, wherein the power supply circuit is provided with an interruption part; the interruption part is provided with two broken points; the switching circuit is respectively electrically connected to the two broken points; the switching circuit comprises a presetting unit, a timing unit, a switching unit and a resetting unit; the presetting unit is connected to the timing unit and used for presetting a shutting time; the timing unit is used for sending a shutting signal to the switching unit when the present conduction time reaches the shutting time; the switching unit is used for receiving the signal from the timing unit and switching to a disconnection state to cut off the power supply circuit; and the resetting unit is connected to the switching unit and used for resetting the connection state of the switching unit when the electric control device is started, thereby connecting the power supply circuit. By using the scheme provided by the invention, the shutting function is realized in a timing manner and the electric control device can automatically shut down after running for a period of time, thereby being beneficial for an authorized user to control and use the electric control device and meeting the market requirement.

Description

【Technical field】 [0001] The invention relates to an electric control device, in particular to an electric control device for automatic shutdown. 【Background technique】 [0002] Existing electronic control devices are often set to automatically shut down by software; for example, the timing shutdown system of a computer. Unauthorized users can set and adjust the shutdown settings by themselves, so that the electronic control device is used uncontrollably. [0003] For example, the guardian hopes that the ward can only use the personal computer for one hour a day, but in reality there is a lack of corresponding management means. [0004] Therefore, the prior art needs to be improved. 【Content of invention】 [0005] In view of this, it is necessary to propose an electronic control device for automatic shutdown. [0006] The technical solution of the present invention is as follows: an electric control device for automatic shutdown, which includes a power supply circuit an...
