Detailed ways

Below in conjunction with accompanying drawing, the technical scheme of the utility model is described in further detail:

As shown in Figure 1, a kind of automatic detection alarm device of electric vehicle lighting lamp of the present utility model comprises photosensitive sensor, power supply module, single-chip microcomputer, photoelectric coupler, alarm unit; Wherein, power supply module is used for supplying power to photosensitive sensor, single-chip microcomputer.

The photosensitive sensor is used to detect the brightness value of the current environment, the signal output terminal of the photosensitive sensor is connected with the first signal input terminal of the single-chip microcomputer, and the detected ambient brightness value is sent to the single-chip microcomputer.

The signal input terminal of the photocoupler is connected to the power supply pin of the external electric vehicle lighting lamp, which is used to detect whether the electric vehicle lighting lamp is on, and the signal output terminal of the photocoupler is connected to the second signal input terminal of the single-chip microcomputer , the signal output end of the single chip microcomputer is connected with the signal input end of the alarm unit.

A light intensity threshold is stored inside the microcontroller, and this light intensity threshold is used to judge whether the current ambient brightness needs to turn on the light for illumination. When the MCU receives the ambient brightness value sent by the photosensitive sensor, it compares the current value with the preset light intensity threshold: if the current brightness value is higher than this threshold, it means that the current ambient brightness is sufficient, for example, during the daytime, There is no need to turn on the lights for lighting; if the current brightness value is equal to or lower than this threshold, it means that the current environment is not bright enough. For example, at night, it is necessary to turn on the lights of electric vehicles for lighting. Of course, how to set the light intensity threshold belongs to common knowledge in the field, and does not belong to the content to be protected by the present invention, so no detailed description is given here.

As shown in Figure 2, as an embodiment of the utility model, the photosensitive sensor of the utility model adopts a digital light intensity module, and the alarm unit adopts a voice alarm system. Among them, the digital light intensity module adopts BH1750FVI, and the power supply adopts +5V battery or regulated power supply.

When the electric vehicle is turned on, if the light is turned on, the pin of the single-chip microcomputer connected to the photocoupler is valid at this time; at the same time, the digital light intensity module knows the light situation and sends it to the single-chip microcomputer for comparison with the preset light intensity threshold. After the light exceeds the preset light intensity threshold, the pin of the single-chip microcomputer connected to the digital light intensity module is valid at this time. The voice alarm system works to remind the user to turn off the light switch in time to reduce unnecessary waste. the

Conversely, if the current light condition detected by the digital light intensity module is lower than the preset light intensity threshold, the pin level of the single-chip microcomputer connected to the alarm circuit will not act at this time, and the voice alarm system will not work.
