Description

Technical Field

[0001] The present invention belongs to the technical field of launch measurement and control system design, and relates to a data processing and display system and method applicable to multi-source data input of a control system. Background Art

[0002] When performing front-end and back-end software function interaction between different platforms and devices, the front-end and back-end systems work together. The back-end software is deployed on the back-end main control computer and has an interface, which is responsible for the overall process control, real-time monitoring of test process data, and human-computer interaction operations.

[0003] Under the control of the back-end main control computer, the front-end cooperates to complete test control, system self-check, and centralized monitoring of all information.

[0004] Since the back-end main control computer involves human-computer interaction operations, the display technology of interface parameters is a basic function of all back-end software of the launch measurement and control system. The data processing and display function codes of each project are different, resulting in a variety of display methods. In addition, due to the limited range of the system interface layout, manually changing the interface becomes the only means, resulting in the risk of repeated modification, frequent changes, and high modification costs for interface function changes. Therefore, a reusable and easy-to-reuse front-end and back-end data parsing and display system that is not coupled with other software codes and is applicable to data processing and display of multi-source data input of the control system is needed. Summary of the Invention

[0006] The technical solution adopted by the present invention is:

[0007] A data processing and display system applicable to multi-source data input of a control system includes a front-end and back-end message general template, a data transceiver bus, a data parsing module, and a data display module;

[0008] The front-end and back-end message general template: taking the front-end and back-end message elements as units, providing users with a definition of the front-end and back-end general interface protocol, and converting the defined template into an xml configuration file through format conversion to form a front-end and back-end data parsing and display template; the front-end and back-end data parsing and display template is sent to the data parsing module through the data transceiver bus;

[0009] The data transceiver bus: used to connect the server interface of the back-end application software and the front-end external interface, and to connect the client interface of the back-end application software and the server interface of the back-end application software;

[0014] Preferably, the data display module enters different event branches according to the corresponding data display types to process different display forms.

[0015] Preferably, the server of the back-end application software is responsible for communicating with the front-end and other systems with communication protocol interfaces, summarizing, aggregating, and parsing the received data, and forwarding it to the client of the back-end application software for display through the data transceiver bus; the interface of the client of the back-end application software is only used to display data.

[0016] Preferably, the front-end and back-end message elements include message name, message identifier, message length, message content, and CRC check code.

[0017] The data processing and display method using the data processing and display system for multi-source data input applicable to a control system includes:

[0022] Preferably, the external interface of the data parsing module corresponds one-to-one with the event branches corresponding to each data type.

[0023] Preferably, the external interface of the data display module corresponds one-to-one with the event branches corresponding to each data display type.

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] The present invention is used for front-end and back-end software function interaction between different platforms and devices to achieve reliable transmission of multi-source data. By formulating a set of operation methods and protocols, it is possible to configure the parsing format and display form during the transmission and display of multi-source data, so as to achieve the purpose of being reusable and easy to reuse.

[0032] The data processing and display system of the present invention includes front-end and back-end message elements, front-end and back-end message general templates, a data transceiver bus, a data parsing module, and a data display module. A set of protocols is formulated, and a front-end and back-end common interface protocol, that is, a front-end and back-end message general template, is defined by combining the protocol characteristics of multiple models, and the protocol is converted into the format of an xml configuration file through format conversion, so as to form a front-end and back-end data parsing and display template with front-end and back-end message elements as units. A method for separating the parsing and display services of the back-end application software client and the server is proposed.

[0033] Figure 2This is the working principle diagram of the present invention. Specifically, by combining the analysis of multiple protocol features, a general interface protocol for the front and back ends is defined, that is, a general template for front and back end messages. And through format conversion, the protocol is converted into the format of an xml configuration file, thus forming a front and back end data parsing and display template with front and back end message elements as units. In addition, since the system needs to display data from multiple devices and has a high requirement for the real-time display of data. Therefore, the back-end application software transmits the front and back end data parsing and display template to the data parsing module and the data display module through the data transceiver bus. The server of the back-end application software realizes specific parsing operations by calling the external interface provided by the data parsing module; the client of the back-end application software makes corresponding display actions by retrieving the display key parameters and display control names in the front and back end data parsing and display template.

[0034] The structure diagram of the general message element for the front and back ends is as Figure 1 shown, including message name, message identifier, message length, message content, and CRC check code.

[0035] The data transceiver bus is mainly a bridge connecting the server interface of the back-end application software and the front-end external interface, as well as the client interface of the back-end application software and the server interface of the back-end application software. All parsing and display operations of the back-end application software for messages are always transmitted to the data parsing module and the data display module through the data transceiver bus. While isolating the back-end application program from the data parsing and display function modules, the data transceiver bus also acts as a cache pool to prevent data loss caused by waiting for timely scheduling when the processor performance is insufficient.

[0036] The data parsing module is mainly used to process the data parsing operations of front and back end messages. It is an independent module, and its implementation method is to enter different event branches (such as uint8, uint16, 1bit, float, etc.) according to the corresponding data types for parsing and processing in different formats, so as to calculate the values of the corresponding data. During the operation of the data parsing module, the server software of the back-end application software does not need to know the specific implementation method, and only needs to call the interface provided by the data parsing module according to the format of the front and back end messages. At the same time, the data display module, like the data parsing module, is also an independent module, and its implementation method is also to enter different event branches (such as LAMP, LCD, TABLE, CURVEPLOT, etc.) according to the corresponding data display types for display processing in different formats. During the operation of the data display module, the client software of the back-end application software also does not need to know the specific implementation method, and only needs to call the interface provided by the data display module according to the display format of the key data to be displayed in the front and back end messages. The working scenarios of the above two modules truly achieve the isolation of the application program from the data parsing and data display modules.

[0037] When separating the processing and display of data, the interface of the client software of the back-end application software is only used to display data. The server software of the back-end application software is responsible for communicating with the front-end and other software with communication protocol interfaces, performing complex processing such as summarizing, aggregating, and parsing the received data, and then uniformly packaging and forwarding the processed data to the client software of the back-end application software for display; separating the parsing and display functions from the functions of communicating with external software makes the software highly flexible. The change of one software does not affect the execution and use of the other software, which is convenient for the maintenance of the software's later functions. The whole process only needs to use the general message xml configuration file generated by the protocol, and then make the application program call the external interfaces of the data parsing module and the data display module. When the requirements change, only the correctness of the configuration file needs to be maintained, and the function change can be realized without writing code, which can greatly reduce the workload of software developers repeating code writing and improve the efficiency, quality, and reliability of software development.

[0039] The data processing and display method of the present invention includes the following steps:

[0040] The user defines the front-end and back-end common interface protocol using the front-end and back-end message common template, and converts the defined template into an xml configuration file through format conversion to form the front-end and back-end data parsing and display template;

[0041] The server of the back-end application software receives external input data using the data transceiver bus, and performs summarizing, aggregating, and parsing processing on the received data by using the front-end and back-end data parsing and display template;

[0042] The server of the back-end application software realizes the specific parsing operation by calling the external interface provided by the data parsing module;

[0043] The server of the back-end application software sends the parsed data to the client of the back-end application software through the data transceiver bus;

[0044] The client of the back-end application software calls the data display module, and the data display module makes corresponding display actions by retrieving the display parameters and display control names in the front-end and back-end data parsing and display template.

[0045] In the present invention, the UDP communication command format between the front-end control software and the back-end service software is shown in Table 1. The UDP communication command format between the back-end service software and the front-end control software is shown in Table 3.

[0052] The present invention relates to a data processing and display system and method applicable to multi-source data input of a control system, which is used for front-end and back-end software function interaction between different platforms and devices to achieve reliable transmission of multi-source data. By formulating a set of operation methods and protocols, it is realized that the parsing format and display form of multi-source data can be configured during the process of transmission and display, so as to achieve the purpose of being reusable and easy to reuse.

[0053] The present invention separates the parsing and display functions from the functions of communicating with external software, making the software have high flexibility. The change of one party's software does not affect the execution and use of the other party's software, which is convenient for the maintenance of the software's later functions.
