Embodiment 1
[0048] Take the organization of time object data and the retrieval of data based on the time attribute and spatial data of the data as an example in the present invention.
[0049] The organization of object data includes data definition process and data operation process. Data definition includes realizing the definition of model library data and engineering library data through spatial dimension and / or time dimension. According to a preferred embodiment, the object to be described is classified into the corresponding category according to the natural attributes of the object, so that the predefined category attribute corresponding to the relevant category is assigned to the object corresponding to the object to be described, including at least the time attribute and the space attribute in advance. The data record for the attribute. The displayed objects can be various things, for example, they can be classified into physical, chemical and biological categories according to ...
Embodiment 2
[0063] On the basis of Embodiment 1, the use of the data graphical members of the present invention is taken as an example. The various data stored in the spatio-temporal data database are a description of objective things, such as on-site temperature values, pressure values, and flow values. , spatial size, spatial location and time information should not only be defined and expressed in the form of natural language, but should also be displayed graphically.
[0064] Taking space as an example, a polygonal graphic member is used to describe the shape of the space. This polygonal graphic member is just a simple polygon at the model stage and does not represent any meaning. However, at the stage of association with specific data objects to be described, spatiotemporal data The polygon member on the object shows the shape of the actual field device, because each spatial object has a shape and geographical coordinates, and this set of coordinate points can determine the position ...
Embodiment 3
[0067] On the basis of Embodiment 1, the use of the data audio and video members of the present invention is taken as an example. Through data collection, the collected on-site audio and video data can be played directly on the display device in the form of real-time data members. In the past, monitoring and management could only collect data and then display it with some vivid graphics. This is like the sensor information members in the past only allowed users to have hands to reproduce on-site information with vivid graphics on the screen, but with audio members and video members, users in the control room have eyes and ears, and can see the information in real time. A live image and listen to live sound.
[0068] Audio and video data will be collected in real time and stored according to the granularity of time and space. For example, if a temperature alarm occurs on duty, it will be used as a trigger condition to record the audio and video information on site when the tem...
