Therefore, all kinds of existing control devices have more or less network functions or network expansion modules.

[0003] Take the control scenario related to the bridge inspection vehicle as an example. The bridge inspection vehicle is a large-scale electric control equipment used for regular maintenance and inspection of bridges. It will be installed under the bridge with a large span. Its frequency of use is low, depending on the maintenance cycle of the bridge. The controller of the bridge inspection vehicle is usually based on PLC, which is relatively expensive, large in size, relatively simple in function, and has a low degree of customization. If the IoT function needs to be expanded, a special industrial gateway module needs to be added, which is more expensive and complex to configure. The display interface of the cloud platform cannot be modified and cannot meet the project requirements of the bridge inspection vehicle. Therefore, for intelligent control, especially remote control scenarios, control devices under new technology applications are needed to improve similar current problems. Utility Model Content
