The invention belongs to the technical field of program control systems, and particularly relates to a Qt-based EtherCAT master station system and a multi-task scheduling method. The system comprises a man-machine interaction module, a task scheduling management module, an EtherCAT master station protocol stack function module, an XML slave station configuration file analysis module, a network port communication module and a serial port communication module. The man-machine interaction module comprises service real-time display and control, EtherCAT communication data online debugging, service basic configuration and modular debugging and system authentication; the task scheduling management module comprises a system working state management module, a complex business data processing module and a task scheduling module; the EtherCAT master station protocol stack function module comprises real-time data processing of a controlled object, business control logic management of a controlled slave station, an EtherCAT master station initialization process and business processing process interface implementation of the controlled object. The development efficiency and the system performance of the EtherCAT master station system are remarkably improved, and the requirements of a modern industrial control system for real-time performance, stability and user experience are met.

The application discloses a kind of data storage method and system based on object chain, which comprises: using N nodes to store data and text;N nodes are linked to form M string chain under the guarantee of security guarantee mechanism;M string chain freely constitutes X object unit;X object unit is linked to form block chain by control library firmware, realize the storage of multiple data and text;The system makes the above-mentioned method carry out data storage and management;System includes support layer, functional layer and interface layer;Wherein, support layer includes: directory service module;Functional layer includes: authentication service module, identity management module, authorization management module, role management module, resource management module and configuration management module;Interface layer includes: API interface module, Web service module and management tool module;Different functional components can be connected through API interface module, can adapt to various different platforms, and the performance is stable and reliable;And data storage efficiency and security are very high, and storage is not limited.

The invention relates to a cross-platform non-intrusive front-end data request security encryption method, which belongs to the technical field of front-end security communication, and comprises the following steps of: detecting a terminal environment of a client by a security component to distinguish the terminal environment, judging whether the current terminal environment is a browser environment or a WeChat applet environment, and if yes, sending the current terminal environment to a server; detection adaptation of a terminal environment is realized; setting a request interceptor of a corresponding type according to the detected terminal environment and data request mode; and the security component calls the request interceptor, carries out underlying API interception proxy on the front-end data request and the server response data, and executes security encryption and decryption and anti-replay processing. According to the method, the development and test efficiency can be improved, the risk of influencing the normal business process is reduced, the front-end request security protection coverage range is increased, and the security blind area is reduced.

The application provides an AR real scene map dynamic superimposed label method, system, device and medium, which is applied to a webpage client and includes the following steps: obtaining video decoding information; obtaining AR label information by analyzing SEI frame information in the video decoding information; generating and rendering an operable label layer according to the AR label information; changing the operable label layer in response to user operation; obtaining new AR label information according to the changed operable label layer; outputting the new AR label information to a backend server to enable the backend server to update SEI frame information according to the new AR label information; and re-rendering the operable label layer in response to update information sent by the client after listening to the updated SEI frame information. Through webpage program development, the AR real scene map dynamic superimposed label method provided by the application has cross-platform and dynamic properties, has low development cost, and is flexible to publish. The preview layer and the operable label layer of the application are decoupled, the program complexity is reduced, and the business flexibility is improved.
