Car security system

The alarm system is a set of technical tools to be installed on vehicles (mainly cars) to prevent their theft and other unauthorized use. Anti-theft system is divided into informing, tracking, and blocking resistance. Informing anti-theft systems (car alarm) designed to inform the owner, law enforcement officials or other individuals about the fact of intrusion into the vehicle and attempted to hijack. By way of transferring the information signal are distinguished: speaker informs only with acoustic transmitters (sirens) that are installed on the vehicle. Radio signals to inform through the transfer of radio signals at the terminal, located in the holder and the combined signals include both types of alerts. The tracking security system informs the owner via the dispatch center to the itinerary of unauthorized movement of the vehicle with navigation systems and warning by radio. Blocking security system make it impossible to start the vehicle engine, shifting gears, locks the steering or brakes. The kit includes an immobiliser unit, engine blocks, and the tag that this block is read. There are different forms of tags: cards, tablets, petals, etc. If you want to start a car, you must either attach a label to the reader an immobiliser or inserted into the reader immobiliser or make a reception area immobiliser from 30-40 centimeters to 15 meters. Blocking the engine start in three ways: disruption of normal transmission of control signals in the wiring of electrical equipment by using relays controlled anti-theft system. The second way is to block the software works Controller fuel injection system. The third way is a violation of normal fuel supply to the engine by means of valves controlled by the anti-theft system. Locking gear the car using mechanisms that make it impossible to move the gear lever. Drive locking mechanism may be electrical or mechanical. The lock making it impossible in a closed state rotation of the steering shaft locks the steering. The lock blocks the braking system. Alarm system is a mechanical valve, which transmits the brake fluid to the pads, due to which the inhibition occurs in normal mode, i.e. proportional to the pressure on the brake pedal, but the back brake fluid is not released. Thus, it is necessary to transfer the system to the position of security and after the first all-wheel drive vehicle braking will be blocked.
