An automatic switching machine circuit and automatic switching machine method applied to a router

Abstract

The invention discloses an automatic switching machine circuit and automatic switching machine method applied to routers, including a power supply circuit, a level control circuit, a power-on time setting circuit, a latch circuit, an oscillation circuit, a counter, a logic circuit and a control chip, and a power supply circuit Supply power to the level control circuit, power-on time setting circuit, latch circuit, oscillator circuit, counter, logic circuit and control chip respectively; the level control circuit changes the control level and connects to the control power supply circuit; the latch circuit connects to the oscillator circuit, and the oscillator circuit Connect the level control circuit; the oscillator circuit is connected to the counter, the counter is connected to the logic circuit, the logic circuit is connected to the level control circuit, the power-on time setting circuit is connected to the logic circuit; the control chip is respectively connected to the latch circuit, the power-on time setting circuit and the level control circuit, It allows users to pre-set the shutdown and startup time of the router, and then the router automatically completes the shutdown rest and automatic startup work.

Description

technical field [0001] The patent of the present invention relates to an automatic timing switch circuit of electronic equipment, specifically, an automatic switch circuit and an automatic switch method applied to a router. Background technique [0002] A router is a device connected to various LANs and WANs in the Internet. It will automatically select and set routes according to the channel conditions, and send signals in the order of the best path. The router is the hub of the Internet, the "traffic policeman", widely used in all walks of life. Various routers of different grades have become the main force to realize the internal connection of various backbone networks, the interconnection between backbone networks, and the interconnection between backbone networks and the Internet. The main difference between routing and switching is that switching occurs at layer 2 (the data link layer) of the OSI reference model, while routing occurs at layer 3, the network layer. Th...
