It should be understood that, in the present novel light monitoring unit, the photosensitive sensor is specifically a photodiode. The photodiode is similar to a semiconductor diode in structure, and the tube core is a PN junction with photosensitive characteristics and has unidirectional conductivity. Referring to the schematic diagram of the circuit structure of the optical monitoring unit shown in fig. 2, a circle 1 of a connection point between RP1 and R1 represents an electrical connection position 1 between the output terminal of the optical monitoring unit circuit and the input terminal of the first processing unit circuit. The photosensitive diode VD1 is reversely connected with a working voltage VCC, no ambient light exists at night, only small saturated reverse leakage current, namely dark current, exists in the VD1, and the VD1 is in a cut-off state at the moment; in daytime, the ambient light is sufficient, at this time, the saturated reverse leakage current in the VD1 is greatly increased, and finally the VD1 is turned on to form a photocurrent, and the magnitude of the photocurrent has a direct relationship with the intensity of the ambient light, that is, the magnitude of the current on the branch circuit related to the VD1 has a direct relationship with the intensity of the ambient light.

It is understood that the second processing unit may output a corresponding switch signal to the driving unit by receiving the light sensing signal related to the external light intensity, and specifically, send a pulse to the driving unit based on the short-time light intensity information change, the U2 may obtain the corresponding light intensity information according to the analog quantity received by the input pin and send the corresponding light intensity information to the U3, and the U3 sends the pulse level corresponding to the digital quantity parameter to the driving unit according to a preset algorithm.

For example, it is assumed that the ambient light intensity information corresponding to the night is 0, and the ambient light intensity corresponding to the occurrence of lightning is 100; when no lightning exists, the environment is kept dark, the U2 is set to send a digital signal of "0000000" to the U3 when the acquisition ambient light intensity is 0, and send a digital signal of "0000001" to the U3 when the acquisition ambient light intensity change is 100; and U3 is set to send a low level pulse to the drive unit upon receiving the digital signal "0000001" and a high level pulse to the drive unit upon receiving the digital signal "0000000", thus enabling the sending of a switching signal to the drive unit based on ambient light changes in the night.

It can be understood that in the novel circuit structure, the output of the U3 adopts a strong push-pull mode, so that the 7 th pin of the U3 is connected in series with the resistor R7 with the resistance value of 15K as an output pin. Optionally, the output of U3 may also adopt a weak pull-up mode, in which a pull-up resistor of 10K is added.

Referring to the schematic diagram of the driving unit circuit shown in fig. 5, a circle 2 of a connection point indicates an electrical connection position 2 between the output end of the first processing unit and the driving unit circuit, and a circle 3 of a connection point indicates an electrical connection position 3 between the output end of the second processing unit and the driving unit circuit.

It can be understood that the novel driving unit comprises a triode Q1, a pull-method capacitor C2 and a relay K1; the base set of the triode Q1 is connected with the output ends of the first processing unit and the second processing unit, the collector of the triode Q1 is connected with the control end of the relay K1, the emission set of the triode Q1 is grounded in parallel with the negative electrode of the Czochralski capacitor C2, and the positive electrode of the Czochralski capacitor C2 is connected with the working voltage VCC; the transistor Q1 is used for controlling the relay K1 to be opened or closed based on a preset switching signal; relay K1 is used to turn on the AC power when closed.

Understandably, when the electric connection position 2 and/or 3 is high level, the triode Q1 is conducted, the relay K1 is attracted, and therefore the AC power supply is conducted, and the LED lamp of the aviation obstruction light can work; when the electric connection position 2 and/or 3 is low level, the triode Q1 is cut off, the relay K1 is disconnected, the AC power supply is not conducted, and the LED lamp of the aviation obstruction light does not work.

It should be noted that, since the first processing unit directly outputs the high-low level switch signal according to the level threshold value at the electrical connection position 1, and the second processing unit performs the predefined processing on the level at the electrical connection position 1 to obtain the corresponding light intensity information, so as to output the pulse level switch, that is, the switch signal generated by the first processing unit and the switch signal generated by the second processing unit are based on different types of parameter information, and the first processing unit and the second processing unit are both set to output the high level when there is light and output the low level when there is no light, but the responses to the light intensities are different, so that the situation of collision does not occur. For example, at night, the photodiode is kept in an off state, that is, the electrical connection position 1 is kept at a low level, at this time, the first processing unit outputs a high level to turn on the transistor Q1, the AC power supply is turned on, and the lamp starts to work; when lightning appears in the night, the duration of light is short, the intensity is insufficient, the first processing unit may not respond to the lightning, the second processing unit can output low level to cut off the triode Q1 when the light intensity information reaches the preset definition based on the preset definition, the AC power supply is disconnected at the moment, the protection device cannot attract the lightning, and after the lightning day is over, the first processing unit can control the AC power supply to be conducted again due to continuous no light, so that the device works normally.

It can be understood that the novel operating voltage VCC is obtained by AC power conversion, and further, when the relay K1 is closed, the operating voltage VCC can charge the farad capacitor C2. The specific circuit for implementing the voltage conversion and the specific operation of the obstruction light are not described herein again.

It will be appreciated that the pull-through capacitor C2 is used to provide the operating voltage VCC to the photo-control module when the relay K1 is open. Specifically, the capacitance of the farad capacitor C2 is greater than 240F, so that the normal operation of the light control module can be ensured.

Further, a diode D1 connected in the reverse direction is disposed between the collector of the transistor Q1 and the operating voltage VCC, and is used for protecting the Q1 from the reverse current breakdown caused by the conduction of the K1.

Specifically, the transistor Q1 has a model S9614, and the diode D1 has a model IN 4148.
