Central locking with remote control - convenience and safety

The central locking with remote control is an electronic-mechanical system responsible for closing and unlocking all car doors, including the trunk and the fuel tank cap. In addition to the function of simultaneous unlocking of all doors, the device is also equipped with a decentralized system that allows opening and closing only those car doors that are needed at a particular moment.

How does the central locking with remote control work?

A complete central locking with remote control is provided for all locking systems. It includes several mandatory elements, namely, special mechanisms that receive and respond to the signal; Control unit of the HZ; Output sensor.

Much more convenient when the system is equipped with a common control unit responsible for each individual door. The remote control unit of the central lock receives a signal from the remote control, processes it and makes the doors open. The input sensor, consisting of switches built into the doors, microswitches and mechanisms, transmits information to the main control unit through the unit for different doors and lock elements, and the latter in turn provides a signal that turns the action of the actuators into electrical power signals of the mechanical Movement. In the event of failure of the limit switch, the car owner will not be able to perform any actions with the doors.

Mechanism Functions

For the operation of the actuators, the DC motor and the small reducer are responsible. For the production of reducers, the most durable plastic is usually used. The signal coming from the main control unit drives the motor, and the gearbox causes the lock elements to work. The following principle is based on the operation of this control system: a micro transmitter is integrated in the key (key fob), from which a signal is sent to the main unit equipped with a radio antenna. The central locking with remote control is able to interact with the key fob at a distance of up to 15 meters on average. After the intentional signal is detected, the main unit transmits a special signal to the blocks responsible for opening / closing each door, after which the mechanism is turned on.

Central locking remote control system

Remote opening / closing of different doors is carried out after pressing a special button located on the key or key fob. After the door closing function is activated, actuators (actuators) are activated, which terminate the specified process. At the same time as the central locking with remote control closes all doors, the interlock is activated and the alarm system is started. The anti-theft alarm system has a feedback to the remote control, which can signal the car owner of an attempt to unauthorized autopsy. However, please note that the warning radius is small.
