Combined type anti-theft system for storage battery, and control method of combined type anti-theft system

The invention discloses a combined type anti-theft system for a storage battery. The anti-theft system comprises an electric circuit part, a gas circuit part, a normally closed electromagnetic valve and a gas cut-off valve, wherein the electric circuit part comprises a storage battery and a normally open electromagnetic valve; the positive pole 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 pole end of the normally open electromagnetic valve; the negative pole end of the normally open electromagnetic valve is connected with the negative pole end of the storage battery; the gas circuit part comprises a gas storage cylinder and a gas horn; the gas storage cylinder is communicated with the gas inlet of the normally open electromagnetic valve; the exhaust opening of the normally open electromagnetic valve is communicated with the gas horn; the positive pole end of the normally closed electromagnetic valve is connected with the positive pole end of the storage battery; the negative pole end of the normally closed electromagnetic valve is connected with the negative pole end of the storage battery; the gas inlet of the normally closed electromagnetic valve is communicated with the gas storage cylinder; the exhaust opening of the normally closed electromagnetic valve is communicated with one end of the gas cut-off valve; the other end of the gas cut-off valve is communicated with the gas horn. The combined type anti-theft system is good in theft preventing effect, and does not influence the normal running of a vehicle.
