The main advantages are that: 1) the problem that the traditional chip protection device cannot be remotely monitored, checked and managed in operation and maintenance due to the fact that the device does not have a display is solved; 2) the display mode of the virtual panel is adopted, and the display method has the advantages that operation and maintenance personnel familiar with the original protection human-computer interface can continue the former operation and maintenance habit, and stable transition of novel equipment maintenance such as chip protection is realized.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
