Abstract

The invention relates to a capacitor type flasher circuit with a weather situation recognizing function. The flasher circuit comprises a weather situation detecting circuit, a current relay, an electromagnet, an elastic conductive plate, a conductive base, a static contact, a dynamic contact and a capacitor. The weather situation detecting circuit controls the actions of a relay KA so as to changethe flashing frequency of a capacitor type flasher. The flashing frequency of the capacitor type flasher can be changed according to the changes of weather situations, and therefore the driving safety is improved.

Description

technical field [0001] The invention relates to the field of engineering electrical equipment, in particular to a capacitive flasher circuit and a control method with the function of identifying weather conditions. Background technique [0002] The flasher is a flashing device used to indicate changes in the driving direction of the car and to warn. The existing flasher is designed with a new type of circuit, which is composed of a low-voltage switch circuit, a high-voltage switch circuit, a pulse generating circuit, a two-pole amplifying double-tube output circuit and two groups of light indicating circuits. It is installed in the flasher box, and its control can accurately indicate the driving direction of the vehicle. It has the characteristics of protection, and it can automatically stop the flasher and the bulb when the circuit is short-circuited. Some fault indications show the working status of the flasher intuitively, and can find and eliminate faults at any time. ...
