Abstract

The invention relates to an elevator security encryption system. The elevator security encryption system comprises an elevator main controller, a car roof control module, an external call module and aprogrammable device. The programmable device writes encrypted data into the elevator main controller, the car roof control module and the external call module separately. The elevator main controllerwrites encrypted data into the car roof control module and carries out security authentication and locking on the car roof control module regularly. The elevator main controller writes encrypted datainto the external call module and carries out security authentication and locking on the external call module regularly. The encryption system can effectively guarantee the data security, prevents anelevator control system from being attacked by external equipment, and improves the security, integrity, confidentiality and reliability of the elevator control system.

Description

technical field [0001] The invention relates to an encryption system, in particular to an elevator security encryption system. Background technique [0002] With the rapid development of computer technology, communication technology and control technology, the intelligentization of buildings and buildings has become a reality. As one of the important means of transportation in intelligent buildings, elevators have been widely used in residential buildings, shopping malls, office buildings, public transportation and other public place. Serial communication is widely used in elevator control systems due to its advantages of convenient wiring and mature resources. However, in the prior art, due to the wide application and popularization of serial communication, it is relatively easy to be imitated and invaded. Therefore, based on serial communication, how to ensure the safety of elevator data transmission without affecting its transmission efficiency has become a new research...
