Light-beam-excitation type logical protection emitter coupling high-power automobile lamp alarm system

Abstract

The invention discloses a light-beam-excitation type logical protection emitter coupling high-power automobile lamp alarm system. The light-beam-excitation type logical protection emitter coupling high-power automobile lamp alarm system is mainly composed of an audio device HA, a control circuit connected with the audio device HA, a triggering circuit connected with the control circuit, a photo-resistor RL connected with the triggering circuit and a capacitance multiple circuit connected with the triggering circuit, and is characterized in that a light beam excitation type logical amplifying circuit is further connected between the photo-resistor RL and the control circuit in series, and a logical protection emitter coupling type amplifying circuit is further connected between the light beam excitation type logical amplifying circuit and the negative pole of the audio device HA in series. By means of the light-beam-excitation type logical protection emitter coupling high-power automobile lamp alarm system, an alarm can be automatically given when a driver forgets to turn off automobile lamps, the condition that power of a vehicle-amounted storage battery is used up can be effectively avoided accordingly, and the service life of automobile bulbs and the service life of the storage battery can be prolonged to the maximum degree.

Description

technical field [0001] The invention relates to an alarm system, in particular to a light beam excitation logic protection emitter coupling high-power automobile lamp alarm system. Background technique [0002] Cars are the most widely used means of transportation at present, but many car drivers often forget to turn off the headlights after parking. When the car is restarted next time, the electric energy of the car battery has been exhausted, and the engine cannot be restarted. Case. In addition, sometimes when the vehicle is running, the headlights are turned on in broad daylight, and the driver does not know it at all, which will not only seriously reduce the service life of the lights, but also shorten the service life of the battery, which is not conducive to the current energy-saving needs. Contents of the invention [0003] The purpose of the present invention is to overcome the defect that there is no device on the market that can report to the police in time aft...
