Referring to fig. 1 and fig. 2, as shown in fig. 1, a specific application scenario diagram of a satellite real-time data processing method provided in the embodiment of the present application is shown, where the application scenario includes:
(1) the satellite end 10.
(2) The terminal 20 is provided with a visual component, a user uses the visual component to initiate a satellite data acquisition request through an input device such as a touch screen or a keyboard on the terminal, the terminal can be an electronic device such as a smart phone, a smart watch, a notebook computer, a tablet computer or a desktop computer, and the terminal is connected with a server through a wired network or a wireless network.
(3) The measurement and control system server 30, a computer device capable of receiving satellite data, is used to store the upgrade files required for upgrading the visual components, provide download of the upgrade files for the visual components, and connect with terminals through wires or wirelessly and satellites through wireless.
The method is executed through a computer program installed in a measurement and control system server 30, and the measurement and control system server 30 is communicated with at least one terminal 20 and one satellite terminal 10, wherein the measurement and control system server 30 serves as a back end to provide background service, and the terminal 20 serves as a front end to provide an operation interface for interaction with a user.
Fig. 2 is a schematic flowchart of a specific embodiment of a method for processing satellite real-time data according to an embodiment of the present application, including the following steps:
s101, receiving a satellite data acquisition request of a visual component, and requesting a measurement and control system server to acquire satellite related real-time data;
in particular, since the visualization component needs to acquire data, it is necessary to mark the content of the data acquisition. In certain embodiments, step S101 includes obtaining a unique identification of the visualization component, requesting the obtained data, and calling back a function. The data can help the measurement and control system server to accurately acquire the data and can correctly return the data.
Step S102, satellite related real-time data pushed by the measurement and control system server through a WebSocket protocol is obtained, the satellite real-time data are processed and integrated in a specified format, relay data are obtained and stored in an internal memory;
specifically, step S102 includes determining, according to the data requested to be acquired by the visualization component, whether the data required by the visualization component exists in the stored relay data, and initiating, to the measurement and control system server, a data acquisition request for the data requested to be acquired by the visualization component, which does not exist in the stored relay data.
In some embodiments, the step of processing and integrating the satellite real-time data in a specified format includes processing the satellite real-time data into hierarchical data with a directory, which facilitates subsequent data search and classification, so as to improve data processing efficiency.
Step S103, processing and integrating the relay data to obtain data to be displayed, initiating a data push request to a terminal where the visual component is located, and providing the data to be displayed to the visual component for displaying.
Due to the fact that data returned by the measurement and control system server needs to be pushed to the correct visual assembly, before pushing is carried out, the visual assembly needs to be positioned, and therefore data confusion is avoided. In some embodiments, the positioning of the visualization component initiating the satellite data acquisition request may be selected according to a type of visualization component to be pushed in the relay data.
Specifically, since the data acquired by the visualization component may be very huge, the data is handed to the terminal to be processed, which may cause a problem of insufficient calculation, and in order to avoid this, in this embodiment, the data requested to be acquired by the visualization component in the relay data is subjected to ordered sorting and packaging in the smallest unit.
In an embodiment, the step of providing the data to be displayed to a visualization component for displaying includes transmitting the data to be displayed, which is sorted and packaged in order, to a callback function corresponding to the visualization component, and driving the component to perform visualization display.
The following describes a specific implementation process of the embodiment of the present invention with a specific example: for example
Three data are first defined, data 1: the server side pushes data in a uniform format to the client terminal; data 2: the invention implements data format for integrating and processing the data 1 and storing; data 3: the invention implements data of agreed unified format provided to the visualization component.
And the map-like visualization component is used for displaying the current position of the satellite. Some of the parameters are currently configured and this visualization component is initialized and used to show A, B the location information (longitude, latitude, altitude) of two satellites.
Specifically, the following steps:
(1) and the visualization component carries out initialization operation and initiates real-time data subscription.
It needs the position information of two satellites, including three kinds of data of lon (longitude), lat (latitude) and height. The visualization component carries the following three parameters, and initiates data subscription to the implementation of the invention:
parameter 1: a unique identification of this component instance.
Parameter 2: the data parameters required for this component (six).
Parameter 3: callback function
(2) An enforcement data subscription of a visualization component is received.
In the processing process, the data information required by the component is analyzed according to the parameter 2 in the step (1), and six kinds of data (A _ lon, A _ lat, A _ height, B _ lon, B _ lat and B _ height) are judged to be required. At this time, it is determined according to the stored data (data 2), and if other visualization component examples currently subscribe to a _ lon and a _ lat, the server initiates subscriptions to the remaining four data at this time. Similarly, if all the six kinds of data initiate data subscription to the server, then subscription processing is not performed at this time.
(3) And receiving real-time data push (data 1) of the server, processing and storing the data, and integrating (data 2).
The formats of the data pushed by the server side are unified into the previously defined data format (data 1). The data 1 is in a hierarchical structure, and each layer has one or more pieces of data and comprises the following judgment marks: the judgment of the current event (the time point of the data), the judgment of the identification of a specific satellite (which satellite the data belongs to), the judgment of the identification of a specific station device (which device the data originates from), the judgment of the identification of a specific data type (log type, remote measurement type, external measurement type, central system type …), and the judgment of the identification of a specific data attribute (longitude value, latitude value, voltage value …).
The data 1 is subjected to an induction integration process and processed into hierarchical structure data 2 having an explicit "directory". If data 2 is compared to a "document," then the "document" will have multiple levels of indexed directories. Through the 'directory' formed by induction and integration, the data required by the visual component can be conveniently found out.
The first level "directory" is the satellite to which the data belongs.
The second layer "directory" is the instrumentation equipment that generates the data association.
The third layer of directory is the main category of data (log category, remote measurement category, external measurement category, central system …)
The fourth level "directory" is the specific data attribute (longitude, latitude, voltage …)
And in the fourth layer of directory, the data pushed by the server is integrated into ordered data which is ordered according to time. And additionally and individually place (update) the latest valid value of a type of data under this layer of directory.
(4) And after the data 2 is integrated, analyzing the visual components related to the updated data.
If the server side subscribes to data required by a plurality of visual components, analyzing the data pushed by the server side this time to obtain a result that only three attribute correlations (a _ lon, a _100, C _ lon) are pushed, and then we can obtain the following conclusion: this visualization component requires six sets of data (A _ lon, A _ lat, A _ height, B _ lon, B _ lat, B _ height), because the set of data A _ lon it requires is updated, so this component needs to be updated.
(5) The method integrates data 3 required by the updating of the visual component into the data 2, and then drives the component to display
Data 3 is in a uniform format that is handed to the visualization component for use. And packaging the data 2 by taking the 'catalog 4' as a unit to form ordered data. Since the "directory 4" of the data 2 contains an indefinite amount of data, the reprocessing is very costly in the case of a large amount of data. Each "directory 4" of data 2 is the smallest unit of a wrapper.
And transmitting the assembled data 3 into a callback function corresponding to the component, and driving the component to perform visual display.
The process from sending a data acquisition request to visualizing the data of one visualization component is completed through the steps, all real-time data related to the satellite are processed uniformly, and a uniform agreement is established with all visualization components. The convention of the unified standard can simply and conveniently interact with the upstream and downstream of the data. The different assemblies share the same required data, so that the occurrence of redundant data is avoided, and the occupation of a memory is reduced.
