Specifically, as shown in fig. 3, the signal comparison circuit 12 includes an and gate comparator U1 and an or gate comparator U2, and the and gate comparator U1 and the or gate comparator U2 are electrically connected. The and gate comparator U1 includes a signal input terminal a1, a signal input terminal a2, a signal input terminal Y1, a signal input terminal a4, a signal input terminal B4, a signal output terminal Y4, a voltage input terminal VCC, and a ground terminal GND. The or gate comparator U2 includes a signal input terminal a11, a signal input terminal B11, a signal output terminal Y11, a voltage input terminal VCC1, and a ground terminal GND 1. Preferably, the and gate comparator U1 in this embodiment is a 7408 and gate comparator, and the or gate comparator U2 in this embodiment is an or gate comparator.
The signal input terminal a1, the signal input terminal B1, and the signal input terminal a4 respectively receive a control signal output by the main control circuit 10, the signal input terminal B4 is electrically connected to the voltage input terminal VCC, and the voltage input terminal VCC receives a voltage signal input by the main control circuit 10, where a voltage input to the voltage input terminal VCC by the main control circuit 10 is variable, for example, when the main control circuit 10 outputs a first positioning control signal to the signal comparison circuit 12, the voltage of the voltage input terminal VCC is a low level signal; when the main control circuit 10 outputs the second positioning control signal to the signal comparison circuit 12, the voltage at the voltage input terminal VCC is a high level signal.

Preferably, the led D1 emits green light when turned on, and the led D2 emits red light when turned on.
Thus, when the main control circuit 10 outputs the first positioning control signal, the low level signal, the first deflector rod control signal or the second deflector rod control signal, the first key control signal to the and comparator U1, or when the main control circuit 10 outputs the second positioning control signal, the high level signal, the first deflector rod control signal, the first key control signal, or the second key control signal to the and comparator U1, the main control circuit 10 outputs the high beam turn-on signal to the light control circuit 16, the light emitting diode D1 is turned on, and the light control circuit 16 emits green light.
When the main control circuit 10 outputs the first positioning control signal, the low level signal, the second deflector rod control signal or the second deflector rod control signal, and the second key control signal to the and comparator U1, or when the main control circuit 10 outputs the second positioning control signal, the high level signal, the first deflector rod control signal, the first key control signal, or the second key control signal to the and comparator U1, the main control circuit 10 outputs the high beam turn-off signal to the light control circuit 16, the light emitting diode D2 is turned on, and the light control circuit 16 emits red light.
It can be seen that the light control circuit 16 can display the information of turning on or off the high beam to the driver in real time.
Therefore, the high beam control circuit of the embodiment can realize that the high beam can be turned on or off by normally turning on or off the high beam shift lever when the position of the automobile is not in a preset area, such as a city area. The automobile far-reaching light can be turned on or off only by turning on or turning off the key switch, when the automobile is located in a preset area such as a city area, the situation that the driver drives in the opposite direction to the driver due to the fact that the driver turns on the far-reaching light by mistakenly operating the high-reaching light deflector rod under the condition that the road light in the preset area such as the city area is good when the driver drives at night is avoided, and the probability of traffic accidents is reduced.
It should be noted that the above is only the preferred embodiment of the present invention, but the design concept of the present invention is not limited thereto, and all the insubstantial modifications made by using the design concept of the present invention also fall within the protection scope of the present invention.
