Laser remote control switch system

Abstract

The invention relates to a laser remote control switch system which comprises a laser source and a control circuit, the control circuit comprises a power supply, an electronic device, a first electrode, a second electrode and a photosensitive element, and the power supply, the electronic device, the first electrode, the photosensitive element and the second electrode are electrically connected in sequence to form a loop. The light-sensitive element comprises two nano-fiber actuators, the two nano-fiber actuators bend and actuate along with the change of the temperature to enable the control circuit to be switched off or switched on, each nano-fiber actuator comprises a composite structure body and a vanadium dioxide layer, the composite structure body comprises a carbon nano-tube wire and an aluminum oxide layer; the aluminum oxide layer coats the surface of the carbon nanotube line and is coaxially arranged with the carbon nanotube line, the vanadium dioxide layer coats the surface of the composite structure body, and the vanadium dioxide layer and the composite structure body are not coaxially arranged.

Description

technical field [0001] The invention relates to a laser remote control switch system. Background technique [0002] Commonly used remote control devices include radio remote control devices and infrared remote control devices. These two types of remote control devices are commonly used in industries such as industrial remote control, home appliance remote control, and toy remote control. The advantage of wireless remote control switches is that the control distance is long and the control distance can reach More than tens of meters, the disadvantage is that when the carrier frequency is the same, it may interfere with other remote control devices and other electrical appliances, and the transmitter signal needs to be modulated, and the receiver needs demodulation circuits and amplifier circuits, so the circuit structure is more complicated; the advantages of infrared remote control switches The interference is small, generally only a few meters of remote control distance, in...

[0002] Commonly used remote control devices include radio remote control devices and infrared remote control devices. These two types of remote control devices are commonly used in industries such as industrial remote control, home appliance remote control, and toy remote control. The advantage of wireless remote control switches is that the control distance is long and the control distance can reach More than tens of meters, the disadvantage is that when the carrier frequency is the same, it may interfere with other remote control devices and other electrical appliances, and the transmitter signal needs to be modulated, and the receiver needs demodulation circuits and amplifier circuits, so the circuit structure is more complicated; the advantages of infrared remote control switches The interference is small, generally only a few meters of remote control distance, infrared rays generally cannot pass through walls, and do not interfere with receiving devices in other rooms. The disadvantage is that the control distance is not far, and there are also dozens of meters, but the cost is high. At the same time, the power consumption is also large, and the transmitted signal needs to be modulated, and the receiver needs to be demodulated and amplified before it can be used.
