Alarm device preventing storage battery of vehicle from being stolen and control method thereof

Abstract

Provided is an alarm device preventing a storage battery of a vehicle from being stolen. The alarm device comprises an electric circuit part and an air circuit part. The electric circuit part comprises the storage battery and a normally open solenoid valve. The positive electrode end of the storage battery is connected with one end of a horn button, the other end of the horn button is connected with the positive electrode end of the normally open solenoid valve, and the negative electrode end of the normally open solenoid valve is connected with the negative electrode end of the storage battery. The air circuit part comprises an air reservoir and an air horn. The air reservoir is communicated with an air inlet of the normally open solenoid valve, and an air outlet of the normally open solenoid valve is communicated with the air horn. The alarm device further comprises a normally closed solenoid valve. The positive electrode end of the normally closed solenoid valve is connected with the positive electrode end of the storage battery, and the negative electrode end of the normally closed solenoid valve is connected with the negative electrode end of the storage battery; an air inlet of the normally closed solenoid valve is communicated with the air reservoir, and an air outlet of the normally closed solenoid valve is communicated with the air horn. The alarm device not only is good in anti-theft effect but also does not affect normal operation of the vehicle.

Description

technical field

[0001] The present invention relates to a vehicle alarm device, in particular to a vehicle battery stolen alarm device and its control method, which is mainly applicable to vehicles with air horns when the battery is stolen, the air horn sends out a strong alarm sound to the surrounding The crowd and vehicle users will prompt that the vehicle battery is in a state of being stolen. Background technique

[0002] In recent years, more and more customers have reported the phenomenon of battery theft, which has seriously affected the operation and use of vehicles. An effective method to prevent battery theft has become an urgent need for customers and automobile manufacturers. In the traditional vehicle circuit system, the battery is used as a power source to provide electric energy to the vehicle electrical system, and the air horn only plays a warning role during normal use, and cannot play an alarm role when the battery is stolen. During the working process of...
