Detailed Description
The application will be further illustrated with reference to specific examples. It is to be understood that these examples are illustrative of the present application and are not intended to limit the scope of the present application. Furthermore, it should be understood that various changes and modifications can be made by one skilled in the art after reading the teachings of the present application, and such equivalents are intended to fall within the scope of the application as defined in the appended claims.
The embodiment of the invention relates to a modularized data sensing system, as shown in fig. 1, which comprises a sensing system, wherein the sensing system is connected with a plurality of sensing modules through a plurality of hot plug interfaces, and the hot plug interfaces comprise an identification interface component part and a data interface component part; the identification interface component is used for identifying the ID information of the sensing module; the data interface component is used for communicating with the sensing module; and the perception system updates the data interface component according to the ID information identified by the identification interface component.
Specifically, in this embodiment, the ID information of the sensing module is identified by the identification interface component, so as to obtain whether the data type of the sensing module changes, and when the ID information of the sensing module changes, it indicates that the data type of the sensing module changes. After the identification interface component identifies the ID information change of the sensing module, the sensing system can find the corresponding data interface component according to the identified ID information of the sensing module, so that the data interface component is updated, and the problem caused by the difference between different data sensing requirements is avoided.
The hot plug interface in this embodiment further includes a detection interface component, where the detection interface component is configured to detect whether the hot plug interface is inserted into the sensing module, and the sensing system controls a use state of the data interface component according to a detection result of the detection interface component.
When the detection result of the detection interface component is that the sensing module is removed, the sensing system controls the data interface component to be in a disabled state; when the detection result of the detection interface component is that the sensing module is inserted, the sensing system controls the data interface component to be in an on state.
The workflow of the present embodiment, as shown in fig. 2, specifically includes the following steps:
When the system is running, the ID information and interface state of the sensing module are continuously inquired, and when the state of the detection interface component or the identification interface component is found to be changed, the detection interface component is used for detecting whether the plug event of the sensing module is generated or not. If a hot plug change event occurs, the main body or the body respectively performs an enabling or closing operation of the data interface, namely when the sensing module is removed, the sensing interface component detects the removal of the sensing module, the sensing system closes the data interface component corresponding to the sensing module according to the information, when the sensing module is inserted, the sensing system detects the insertion of the sensing module, reads the information of the identification interface component according to the information to obtain the data type of the inserted sensing module, and configures the corresponding data interface component according to the data type of the sensing module, for example, when the data type of the sensing module sensed by the sensing system is a voltage current signal, the sensing system configures the analog interface. If the detection interface component does not change, the detection interface component does not generate a hot plug event, whether the identification interface component changes is detected, when the identification interface component changes, the ID state of the sensing module is changed, the sensing system needs to read the identification interface component again to obtain ID information after the sensing module is changed, the data type of the sensing module is determined according to the ID information, and the data interface component is dynamically updated according to the data type as a main body or a main body, so that dynamic updating configuration is completed. After completion, the sensing system resumes the previous operating state and starts the next poll.
It is easy to find that the identification part is added in the hot plug interface to identify the ID information of the sensing module, when the ID information of the sensing module changes, the sensing system can read the identification interface component again to obtain the ID information of the corresponding sensing module, and reconfigure the data interface according to the ID information.
