Problems solved by technology

[0003] Aiming at the deficiencies of the prior art, the present invention provides a protection method for the electrical parameters of construction machinery, which performs local and remote double protection on the successfully modified parameters respectively. Therefore, after the construction machinery is powered off, the local backup storage or The electrical parameter information stored in the remote server is used as the working parameters stored when the construction machinery is powered off, so as to effectively overcome the defects in the prior art that the data cannot be recovered quickly after power failure and the construction machinery can work normally

Embodiment Construction

[0016] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0017] like figure 1 As shown in 3, the display screen performs parameter modification. After the modification, the controller saves power-off. After confirming the local data backup, it is saved in the display screen or the storage space of the controller. The controller data is transmitted to the mobile terminal, and the mobile terminal sends the The data is transmitted to the remote server and distributed to each host according to the load of each host.

[0018] When restoring data, if you perform local restoration, you only need to copy the local data saved by the display screen or the controller to replace the current data; if you execute remote restoration, the server data will be transmitted to the designated mobile terminal through GPRS, and the mobile terminal will transmit it to the controller through bus communication. device an...

Abstract

The invention discloses a method for engineering device electrical parameter protection. The method comprises a data modification storage step and a data recovery step. In the data modification storage step, electrical parameter information confirmed to be successfully modified is stored respectively in a local backup storage mode and in a remote server storage mode. The data recovery step comprises the following substeps: when an engineering device recovers to work after power down, the electrical parameter information stored in a remote server is taken to serve as working parameters stored when the engineering device is subject to power down or the electrical parameter information stored in a local backup is directly taken to serve as working parameters stored when the engineering device is subject to power down. Therefore, the method effectively overcomes the shortcoming that data recovery cannot be performed quickly after power down and the engineering device cannot work normally in the prior art.

Description

technical field [0001] The invention relates to a method for protecting electrical parameters of engineering machinery, which belongs to the technical field of engineering machinery. Background technique [0002] The current advanced control system parameters of construction machinery generally adopt the form of power-down storage. Usually, the electrical parameters leave the factory after multiple adjustments. After the parameters are modified and cannot be restored due to human or environmental factors, the desired effect can only be achieved after multiple adjustments. , Even after the parameters are modified, the modification position cannot be found, which makes the equipment not work normally and affects the on-site construction. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a protection method for the electrical parameters of construction machinery, which performs local and remote double protection on ...
