Remote terminal anti-disassembly control method suitable for excavator

Abstract

The invention discloses a remote terminal anti-disassembly control method suitable for an excavator. The method comprises the following steps: strengthening the communication safety between a GPS terminal and a main controller through an irreversible encryption algorithm, a cloud end and an EDS algorithm, building reliable object communication connection, carrying out the punishment of a connection destroying behavior, and better preventing malicious disassembly.

Description

technical field [0001] The invention belongs to the technical field of excavators, and in particular relates to a remote terminal tamper-proof control method suitable for excavators. Background technique [0002] The excavator fully utilizes the remote anti-theft control technology for fault maintenance machinery leasing and management, communicates with the controller through the CAN bus, and collects excavator data to display the real-time position of the excavator and various parameters of the equipment in real time, and at the same time receives information from the monitoring center The control command is issued to the CAN bus to realize the command control of the excavator through the excavator controller. Therefore, in order to prevent the abnormal operation of the excavator due to misoperation, it is necessary to improve the remote anti-theft technology, which plays an important role in communication. [0003] The existing GPS terminal and the controller only detect ...

AI Technical Summary

Problems solved by technology

However, the verification method between GPS and the main controller is too simple, and the number of password arrays is small, so it is easy to crack the password, which seriously affects the effectiveness of management and the reliability of remote control of excavators

The communication connection method is too simple, and the punishment for the behavior of the broken connection method is not enough
