Diagnosing method and diagnosing device for elevator network attack

Abstract

The invention discloses a diagnosing method and diagnosing device for an elevator network attack. The method is applied to a cloud server, and an elevator is applied to an information physical system. The method comprises the steps that real-time network monitoring information of the elevator is obtained; whether an elevator network is attacked or not is judged on the basis of the real-time network monitoring information; if yes, an attacked type of the elevator network is acquired; and elevator control operation corresponding to the attacked type is executed. According to the method, the network delay and communication data are monitored in real time, once the network attack exists, corresponding rescue measures are executed immediately, the operation safety and stability of the elevator and the cloud server are guaranteed, and the safe and stable elevator taking experience of a user is guaranteed; and on the other hand, once the elevator network cannot be rescued, network connection is disconnected and an alarm prompt is given, so that the cloud server is effectively protected, meanwhile, corresponding rescue or confrontation measures are taken in time, the elevator operation safety is improved, and the operation benefits of enterprises are guaranteed.

Description

technical field [0001] The invention relates to the technical field of elevator monitoring, in particular to a diagnosis method for an elevator network being attacked and a diagnosis device for an elevator network being attacked. Background technique [0002] With the increasing application of elevators, the conventional offline control methods of elevators are increasingly unable to meet the management needs of elevator manufacturers and the needs of users. [0003] In order to solve the above technical problems, technicians proposed an elevator control system based on a cyber-physical system. In this control system, the elevator manufacturer controls multiple elevators through the high-speed network layer through the main control center located on the main control layer. It can be seen that , the real-time and stability of communication at the network layer is the basis for the reliable and stable operation of elevators based on cyber-physical systems. [0004] In this sy...

AI Technical Summary

Problems solved by technology

[0004] In this system, elevator faults are mainly divided into faults of the elevator itself and faults other than the elevator. The faults other than the elevator mainly come from faults at the network layer, such as wireless communication device faults, network attacks, and network hijacking. The operation of the elevator in the physical system depends on the real-time control instructions of the cloud server, so the network attack and network hijacking against the elevator will greatly affect the operation safety of the elevator, and will seriously affect the safety of passengers when taking the elevator. However, in the existing technology There is no method for diagnosing network attacks during elevator operation, and there is no solution for elevators under network attacks, which cannot meet the actual use needs of elevators
