Abstract
Description
Technical Field
[0001] This invention relates to the field of electronic information and communication teaching, and in particular to a human-computer collaborative practice system for electronic information and communication teaching based on signal punching. Background Technology
[0002] In traditional electronic information and communication (EICT) education, practical teaching of EICT theory is typically achieved through verification experiments. Students set up signal sources and select multiple signal processing algorithm modules within a practical system, assembling these modules according to specific rules and sequences. The system then runs automatically, outputting the signal processing results. By verifying and observing the correctness of these results, the communication theory is validated and put into practice. However, this method fails to allow students to understand and master the computational process of signal processing algorithms, resulting in a missing crucial element in practical teaching. For students to understand and master key algorithms through practice, they need strong computer coding skills. However, lower-level EICT students often only possess theoretical calculation abilities related to EICT and generally lack sufficient coding skills.
[0003] Therefore, how to provide a human-computer collaborative practice system for electronic information communication teaching based on signal punching, which does not require students to have strong computer programming skills but only theoretical calculation skills related to electronic information communication, so that students can understand and master the key algorithms in electronic information communication teaching in practice, is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0004] In view of this, the present invention proposes a human-computer collaborative practice system for electronic information communication teaching based on signal punching.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A human-computer collaborative practice system for teaching electronic information and communication based on signal punching, comprising: an algorithm processing module and a comparison and display module; The algorithm processing module includes n algorithm processing units; each algorithm processing unit includes a signal punching subunit, a signal processing subunit, and a human-machine collaboration subunit. Signal punching subunit: used to extract the signal at the punching position of the signal point in the input signal according to the punching position determined by the random algorithm, and obtain the hole signal, the punching signal and the auxiliary parameters corresponding to the punching signal; Signal processing subunit: used to perform algorithmic processing on the input signal and the hole signal respectively to obtain the complete signal processing result and the hole signal processing result; Human-machine collaboration subunit: used to assist the user in manually processing the punching signal based on auxiliary parameters, and to complete the hole signal processing result according to the manual processing result of the punching signal, so as to obtain the human-machine collaboration signal processing completion result, and input it to the next algorithm processing unit according to the processing order of the algorithm processing unit; The comparison and display module is used to compare and evaluate the complete signal processing results output by each algorithm processing unit and the signal processing completion results of human-machine collaborative processing, and display them through the UI interface.
[0006] Optionally, the number of processing units in the algorithm is n≥1.
[0007] Optionally, the hole signal is the signal generated by extracting the signal from the input signal after the hole is formed in the input signal according to the signal point punching position determined by the random algorithm.
[0008] Optionally, the punch signal is the signal extracted from the input signal at the punch position determined by a random algorithm.
[0009] Optional auxiliary parameters include: signal encoding method, encoding rate, modulation mode, modulation carrier rate, trigger type, and duration.
[0010] Optionally, auxiliary parameters can be used to assist users in manually processing the punching signal, specifically: The auxiliary parameters and drilling signals are displayed to the user through the UI interface; Users manually process the punch signal based on auxiliary parameters and the displayed content of the punch signal, following the processing algorithm requirements given by the system and combining relevant electronic information and communication theoretical knowledge.
[0011] Optionally, the hole signal processing result is completed based on the manual processing result of the punching signal to obtain the human-machine collaborative signal processing completion result, specifically: The manual processing results of the punch signal and the hole signal processing results are synthesized and completed according to the algorithm rules.
[0012] Optionally, the complete signal processing results output by each algorithm processing unit and the signal processing completion results of the human-machine collaborative processing are compared and evaluated separately, specifically as follows: Calculate the similarity between the complete signal processing result and the human-machine collaborative signal processing completion result, plot the similarity curve, obtain the signal distortion, and conduct a comparative evaluation.
[0013] Optionally, the similarity between the complete signal processing result and the human-machine collaborative signal processing completion result can be calculated, including: cross-correlation calculation and error energy calculation.
[0014] As can be seen from the above technical solution, compared with the prior art, this invention proposes a human-computer collaborative practice system for teaching electronic information communication based on signal perforation. By perforating the input signal according to the pre-marked signal point positions, a hole signal, a perforated signal, and corresponding auxiliary parameters are obtained. Based on the auxiliary parameters and the perforated signal, the user manually processes the perforated signal to complete the perforated signal processing result, obtaining a human-computer collaborative signal processing completion result. This result is then input to the next algorithm processing unit according to the processing order of the algorithm processing units. Finally, by comparing and evaluating the complete signal processing result output by each algorithm processing unit with the human-computer collaborative signal processing completion result, the correctness of the user's processing in each algorithm is displayed. This invention enables students to understand and master key algorithms in electronic information communication teaching through practice, without requiring strong computer programming skills, only needing theoretical calculation abilities related to electronic information communication.
