The type of the logic controller is an ESP8266 singlechip, the infrared transmission data of 16-bit system and 10-bit system are transmitted to the infrared transmitter by means of an infrared modulation function, signals are transmitted to the relay forwarding module, the relay forwarding module modulates, de-energizes and amplifies the infrared signal of the 16-bit system and then transmits the infrared signal to the infrared receiver, and the infrared receiver also uses an ESP8266 internet of things module to process the infrared signal of the 16-bit system and then rapidly feeds back the infrared signal to the effect device. The infrared wave of 38khz is taken as a carrier, the anti-interference performance is strong, the ESP8266 internet of things module modulates the intermittent pulse signal string of 38khz, the emitted infrared wavelength is 850 nm-980 nm, the infrared rays in the wave band have good emitting and receiving effects, the emitting effect of an infrared emitting circuit can be improved, and the receiving end is formed by combining an audible and visual alarm module and an infrared receiving module.
The infrared coding data is directly extracted from the < IRremoteESP8266.H > library, and the coding of the data is to send the high-low level of the appointed format through a plurality of periods to control the on-off of the infrared diode. The principle of emitting infrared light at 38khz is that the duty cycle of a wave of 1s/38 khz=26.3 us/(period) pwm is 1/3, i.e. 8.77us emits infrared light and 17.53us does not emit infrared light.
The carrier signal is transmitted within 0.56ms, and one cycle 26.3us requires 560us/26.3 us=21.29 cycles, that is, 8.77us high and 17.53 low are transmitted, and 21 cycles are required. The carrier signal is not transmitted for 0.56ms, that is, 21 periods are required for a low level of 26.53us, and the time for generating a high level of 8.77us (conducting, emitting infrared light) for one clock period is 17.53us (non-conducting, not emitting infrared light).
Specifically, in the utility model, the input end of a first light emitting diode D1 is connected with a D5 port of a logic controller through a first resistor R1, and the output end of the first light emitting diode D1 is connected with a GND port of the logic controller; the input end of the amplifying circuit Q1 is connected with the D2 port of the logic controller through a second resistor R2, the collector electrode of the amplifying circuit Q1 is connected with the grounding end of the logic controller, and the transmitting end of the amplifying circuit Q1 is connected with the Vin port of the logic controller through a second light-emitting diode D2; the input end of the second light-emitting diode D2 is connected with the Vin port of the logic controller, and the output end of the second light-emitting diode D2 is connected with the transmitting end of the amplifying circuit Q1 through a third resistor R3; the positive electrode port of the infrared emission module is connected with the Vin port of the logic controller, the negative electrode port of the infrared emission module is connected with the grounding end of the logic controller, and the signal port of the infrared emission module is connected with the D2 port of the logic controller.

The signal attenuation problem exists in the actual transmission process of the infrared signal, so that the signal cannot be received by the receiving end due to the fact that the signal attenuation is too weak in the transmission process of the infrared signal, in order to increase the transmissible distance of the infrared signal as much as possible, the relay forwarding module is a CMOS phase-locked loop integrated circuit, the signal transmitting direction of the CMOS phase-locked loop integrated circuit can be changed by rotating the transmitting antenna, the relay forwarding module can be used for receiving the signal in advance in the transmission process of the infrared signal, and then transmitting the signal again after the signal intensity is increased, so that the effective transmission distance of the infrared signal can be increased. The relay forwarding module is used for decoding, demodulating, amplifying and transmitting the received infrared signals, and in order to further increase the distance of infrared communication, a plurality of relay forwarding nodes can be manufactured, but some storage forwarding delay is increased.
