Device and method for guaranteeing data security of engineering machinery

Abstract

The invention relates to a device and a method for guaranteeing data safety of engineering machinery, the device comprises a display terminal and a program controller, the program controller is connected with the display terminal through a communication cable, memories are arranged in the display terminal and the program controller, and the display terminal is provided with a button for uploading from the program controller and a button for downloading from the program controller. According to the device and the method for guaranteeing the data security of the engineering machinery, the storage devices are arranged in the display terminal and the program controller, so that a data storage function is realized, and the synchronism and the consistency of data content storage at the two ends are kept; operation buttons of uploading from a program controller, downloading from the program controller and downloading from a cloud data terminal are designed in a display terminal interface, and safety guarantee of engineering machinery data is achieved with the minimum cost investment.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a device and method for ensuring data security of construction machinery. Background technique [0002] On important equipment such as construction machinery vehicles, display terminals and program controllers are installed, and the display terminals and program controllers require data communication, and the two are independent of each other, which can ensure that operators can view and browse real-time operating data through the display terminals , historical data and setting parameters, etc. In the prior art, for example, the display terminal and the program controller on construction machinery vehicles can be data communication with wired connection or wireless connection; some construction machinery vehicles also have cloud data terminal storage function to meet Remote data governance and storage needs. [0003] For construction machinery vehicles without cl...

AI Technical Summary

Problems solved by technology

Although this solution can provide an additional storage method for operating data and parameters, which increases data security control to a certain extent, but for frequent mobile construction machinery vehicles in some construction scenarios due to poor network or GPS signals, it will lead to poor data transmission. Timely, incomplete or even unsuccessful, which will cause the data stored in the cloud data terminal to be invalid

In this case, once an unrecoverable failure occurs at the data storage end of the vehicle, all previous operating data and parameters will be lost, resulting in irreparable results

In addition, there is no cloud data download function in the usual display terminal, and it is impossible to synchronize data from the cloud to the program controller.
