Description

Technical Field

[0001] The present invention relates to the field of satellite testing technology, and in particular to an information protocol soft docking method and system based on text / OCR semantic recognition. Background Art

[0002] During the development of traditional satellites, the number of stand-alone devices varies greatly depending on the different platforms used. Take the integrated electronics of optical remote sensing satellites as an example. The integrated electronics is the information hub for data exchange on the optical remote sensing satellite. Other subsystems of the whole satellite, such as measurement and control, attitude and orbit control, data transmission, visible light camera, power supply and distribution, propulsion, on-board processing, etc., all need to communicate with the integrated electronics. However, due to the different stand-alone information processing systems and data processing capabilities adopted by each contractor, different products have individual differences based on the general communication protocol specifications. Therefore, before each stand-alone product is installed on the satellite, it is necessary to conduct information transmission and reception docking tests to improve the efficiency of the whole satellite development.

[0003] In the docking process of traditional satellites, each physical product is generally subjected to actual docking tests to ensure that the sender and receiver can achieve normal communication functions for the specified send and receive data types. However, due to the variety of onboard products, the large number of research and development units, and the different development progress, it is difficult to get all the products together for docking. It is often necessary to frequently visit different contractors for docking tests, which consumes a lot of manpower, material resources and financial resources. In addition, during the docking process, there will generally be problems with communication interface mismatches due to inconsistent communication protocols. Therefore, it is necessary to determine the cause of the problem in the communication protocol at the docking site according to the provisions in the protocol document, but the process of finding the problem is usually time-consuming and laborious.

[0004] Patent document with publication number IN2014CH04176A discloses a method for testing various hardware interfaces used in the avionics system of an aircraft. In particular, the present invention relates to a method for testing MH1553B, ARINC429, ARINC717, RS232, RS422 interfaces. In this method, a hardware functional test module reads commands from a database and sends commands to test different interfaces of a target system. The target system decodes the command, performs a test of the command, and then sends the test results to the hardware functional test module on the serial interface. The hardware functional test module records the results and provides the health status of all interfaces. The present invention provides a cost-effective method for testing avionics equipment interfaces, which provides multiple advantages, such as automation, reduced complexity, and elimination of data analyzers. The process of finding problems in this invention patent is relatively complex and inefficient.

[0005] Therefore, in the face of the increasingly rapid progress and functional requirements of satellite development, there is an urgent need for a soft docking method based on information data to use information technology to more efficiently and accurately improve the testing efficiency during the satellite development process.

[0052] This method can be used for two forms of docking according to the actual needs of docking. Figure 2 、Connection form 2 Figure 3 .

[0053] In accordance with the agreed information protocol text format, each interface shall be clearly defined in the protocol, including the input and output message format, message type, the meaning of each message field, and the message sending and receiving method. The electrical performance of each interface shall also be clearly defined in the protocol to ensure that no product device damage occurs during the docking process.

[0054] The protocol text is input into the soft docking universal test equipment, and the semantic recognition software in the test equipment is called for recognition. The protocol content is normalized, and the text recognition software discretizes the communication characteristics in the protocol. At the same time, each characteristic is placed in the communication characteristic table of the interface in the form of interface attributes based on the interface.

[0055] The interface communication characteristics are passed to the interface data parsing and processing configuration software, which will perform actual configuration based on the characteristics of each interface. Testers can also check or modify relevant interface properties on the host computer to determine the input and output characteristics of this docking interface.

[0056] After connecting the device to be tested to the corresponding interface of the soft docking universal test equipment, various data transmission and reception tests are performed according to the data types specified in the information protocol. The message type and message content to be tested are selected in the soft docking universal test equipment, and the subsequent transmission and reception test and message content detection process are completed automatically by the soft docking universal test equipment.

[0057] The soft docking universal test equipment compares the received and sent data with the information protocol in each receiving and sending test, screens out the non-conformities with the protocol, marks and explains them in the protocol text, and outputs them. The annotations and explanations of different communication test items are distinguished by colors, and finally a comparison report is output.

[0058] The docking method includes a text / OCR semantic recognition method and a soft docking universal test device. It includes the following steps:

[0059] S1: Text recognition: Input the information protocol text into the soft docking universal test equipment, use semantic recognition software to recognize it, and normalize the protocol content.

[0061] S3: Data reception and transmission test: After the device under test is connected to the corresponding interface of the soft docking universal test equipment, various data reception and transmission tests are performed according to the data types specified in the information protocol.

[0062] S4: Output test report: The soft docking universal test equipment compares the received and sent data with the information protocol, marks and explains the non-conformities with the protocol in the protocol text, and outputs it.
