Embodiment Construction

[0015] All the features disclosed in this specification, except mutually exclusive features and / or steps, can be combined in any way.

[0016] Combine below figure 1 , figure 2 The present invention will be described in detail.

[0017] The key to the infrared emission system is the emission tube and the drive circuit. The working current of the infrared emitting tube is small, and the transmission distance is short. When the current is too large, the signal will be transmitted farther, but the transmitting tube is easily damaged. Infrared light is easily interfered by sunlight, fluorescent lamps, heat sources, etc. during communication.

[0018] This device is mainly used for directional transmission of signals, using infrared light as a carrier to realize information transmission within 2m. The signal provided by the signal source is amplified by the triode, then band-pass filtered, and then amplified by the dedicated audio signal amplifier LM386, and finally the trans...
