Rolling door handle key pairing method and system

Abstract

The invention provides a rolling door handle key pairing method and system. The method comprises the following steps: generating and storing a key and the serial number of a motor controller by a cloud background key maintenance system; programming the key on the motor controller and a chip of a remote control handle by a key programmer; printing the two-dimensional code of the serial number of the motor controller on the motor controller and / or the remote control handle corresponding to the motor controller by a two-dimensional code printer ; and encrypting a transmission code by adopting thekey, and sending the encrypted transmission code to the motor controller by the remote control handle. The key pairing method and system are high in safety coefficient, and are convenient for production installation and after-sale maintenance service.

Description

technical field [0001] The invention relates to the technical field of rolling doors, in particular to a method and system for pairing keys of a handle of a rolling door. Background technique [0002] The remote control system of the electric rolling door is mainly composed of a motor controller and a remote control handle. The motor controller is equipped with a remote control receiving board, and the remote control handle is equipped with a remote control launch board. Response to door opening and closing control commands. The remote control identification codes currently used by the remote control handles on the market mainly include dial codes, million groups and rolling codes. Dial codes and million groups are both fixed codes. The codes sent by the remote control handle each time are fixed and are easy to be copied and sent, which has a low degree of security. The rolling code is a rolling code. The code sent by the remote control handle changes every time. Even if t...

Problems solved by technology

Dial codes and million groups are both fixed codes. The codes sent by the remote control handle each time are fixed and are easy to be copied and sent, which has a low degree of security.

The rolling code is a rolling code. The code sent by the remote control handle changes every time. Even if the code that has been sent is copied and sent, it will be invalid for the controller. Compared with the fixed code, the rolling code is more secure, but Since the rolling code remote control handles use a fixed enterprise code as the secret key, the remote control handles produced by a company usually have the same enterprise code, and the rolling code contains half of the fixed code. When leaked, the remote control handle is easy to be copied, and people with ulterior motives will use it to produce remote control handles with the enterprise code and sell them, causing property losses to the company. loss of life and property
