There will be certain fire hazards in standby for a long time. In addition, unnecessary long standby in thunderstorms will increase This reduces the risk of switches and other equipment being damaged by lightning strikes.

It is modified from an ordinary household switch, including a photocoupler, a solid state relay, a single-chip microcomputer control circuit, a rectifier filter, and an amplification and comparison unit. The utility model is based on an ordinary household switch, and integrates a photoelectric coupler, a single-chip microcomputer control circuit, a solid state relay and a rectification filter into the common household switch. The automatic power-off function is added to the switch when there is no flow, thereby greatly reducing the unnecessary power consumption of the switch when there is no flow. Add a photoelectric coupler to the ordinary household switch to monitor the blinking status of the switch indicator light, and use the on, off and flashing state changes of the switch indicator light to indirectly monitor the transmission of the traffic in the switch; at the same time, use the network cable between the user computer and the switch The change of the power-on signal is used to monitor whether the user's computer is turned on and whether the switch needs to be started. The obtained signal is input into the single-chip microcomputer control circuit, and the built-in program of the single-chip microcomputer control circuit is used to control the switch of the solid-state relay, thereby controlling the opening or closing of the switch.

Monitor the state of the indicator light of the household switch through the photocoupler, and input the signal obtained by the photocoupler into the single-chip control circuit for processing, and then the single-chip control circuit outputs the signal to control the solid-state relay, and finally completes that the switch has no flow, that is, the user computer is shut down Or cut off the power supply in time when the switch is in standby; when the switch needs to be started automatically, by monitoring the change of the power signal on the network line when the computer is started, it is analyzed and processed by the single-chip control circuit after the amplification and comparison unit and the rectification filter, so that the solid-state relay is connected , so as to drive the entire switch to resume work; in addition, the signal obtained by the photocoupler is input into the single-chip control circuit, and the program is set in the single-chip control circuit to control the switch of the solid-state relay, thereby controlling the switch to be turned on or off. After the switch is powered off, the monitoring circuit is powered by a farad capacitor, which minimizes the self-power consumption of the circuit.

Connect the photocoupler with the LED indicator light of the switch, and the photoelectric coupler converts the signal of the LED indicator light of the switch into a high-low level signal through "electricity-optical-electricity" and outputs it to the lower-level microcontroller control circuit, and the signal is processed by the MCU and analyse. In addition, in order to monitor multiple LED indicator lights of the switch at the same time, the utility model adds a logic gate circuit in front of the photocoupler for expansion.
