SK30693A3 - Coding method of remote controlling system of locks and safety devices - Google Patents

Abstract

Code generator (1) and encoder (2) transmitter (3) system blocking and unlocking creates gradual non-repetitive the codes that enter the decoder via the receiver (4) (5), wherein the decoder (5) does not respond to the previous one codes already received

Description

The invention relates to a method for coding a system for remote wireless door locks and security devices with a variable, non-repetitive code.

The prior art is known

The electronic remote control locks used so far use electromagnetic waves to use information to remotely open and close the lock, or to activate, to deactivate a security system in coded form, the coding of which is "implemented by fixed codes, one code opens the lock or disables the security device and the second code closes the lock- or, activates the safety device, always using it. each subsequent opening or closing of an identical _x code with the previous one

From '' '' '7 - l code to open or close.

Such electronic locks and security devices;

due to the use of a fixed, ever repeating code, they have reduced security against; abuse as a result of the possibility of obtaining code 'information by electronic hearing. The control codes thus obtained and recorded allow unauthorized access. subject to overcome, protection by false transmitter.

SUMMARY OF THE INVENTION

These drawbacks are overcome by the wireless control system ¹¹ from topics with variable, unique code, which is based on the fact that the transmitted control code is transmitted. once received by the receiver to unlock or lock the lock or security. zarladenia ^; receiver does not accept but expects ** of \. from another code from the file.

The coding method according to the invention makes it possible to safely protect the security device against misuse by decrypting the code. by; electronic response.

For proper function. The total number of codes is selected at least so that the codes are not depleted over the life of the device.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. . '' ·

In FIG. 1 shows a wireless control system with a variable irreplaceable code according to the invention, in which a code generator, a coder and a transmitter are included in the transmitting part; and a code decoder with an evaluation circuit that controls the power controller ¹ through the control switch.

An embodiment of the invention

The remote control system, with the variable unique code of FIG. 1. consists of a code generator 7, which generates the code, and a coder 2 in which the code is coded and transmitted via a transmitter 3, to a receiving part formed by a receiver 4, a decoder 5 in which the transmitted code is decoded and evaluated, code through the control switch activates the executive device 7 ·

Industrial usability

The coding and decoding method according to the invention is useful for remote contactless operation of locks, security and safety devices with high efficiency against tampering. -
