Abstract
This utility model is a air indicator,belonging to the manufacture technology field of electronic product.It comprises of emit unit, receive device, speaker and fixed mount. receive device is connected with speaker and mounted on the fixed mount together with the emit unit. This device is based on the theory that suspended particle baffles the propagation of infrared ray, while the air's visibility is low and infrared ray sent by the emit unit can not effectivly reach the receives device,speaker will be actived and make a sound so as to reach the objective of showing sweet indication, it may be placed at the cross road and indicate pedestrian and vehicle to be careful when fog or sand storm weather is happened.
Description
Technical field
The utility model relates to a kind of prompting device, belongs to electronic products manufacturing technology field.
Background technology
Along with the quickening of modern life rhythm, the vehicles that people use are also in development at full speed, and the traffic hazard that the increasing of the vehicles caused is also increasing, and one of them reason is exactly the human pilot negligence in that cloudy day or greasy weather visibility poor are arranged.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of practicability and effectiveness, safe and reasonable, the simple visibility safety instruction of manufacturing device.
The purpose of this utility model is achieved through the following technical measures.
This prompting device is made up of emitter, receiving trap, loudspeaker and fixed mount, and receiving trap is connected with loudspeaker and emitter is placed on the fixed mount together.
Described emitter is to be connected to form by radiating circuit and emitting head, radiating circuit be oscillator by integrated circuit modules, resistance, diode, triode, electric capacity are formed, each device is electrically connected.
Described emitter is made up of differential amplifier, triode, resistance and electric capacity, and each device is electrically connected.
The utility model radiating circuit principle of work is that oscillator sends oscillator signal, the outside infrared radiation of infrared light-emitting diode in transistor T 1 is made electric current amplification rear drive emitting head.The receiving circuit principle of work is to make the integrated operational amplifier output low level on the infrared receiver tube T2 when infrared ray shines, and circuit is not had an effect.When infrared ray can't shine on the T2, integrated operational amplifier output high level made music integrated circuit outputting music signal, amplifies through power amplifier, loudspeaker is sounded tell people to take care.This device utilizes airborne suspended particle to hinder the principle of ultrared propagation, when the low visibility of air, the infrared ray that emitter sends can't effectively arrive receiving trap and then drive loudspeaker and sound to reach the purpose of warm tip, and the place, crossing that can be placed on road takes care when dense fog or sandstorm weather prompting pedestrian, vehicle.
