Anti-jamming information processing system and method based on digital frequency modulation and encryption technology

Abstract

The invention belongs to the technical field of communication information anti-jamming, and discloses an anti-jamming information processing system and method based on digital frequency modulation and encryption technology. An instruction issuing terminal is connected to a main control module and used for issuing pairing and power adjustment instructions; Main control module: connected with the command issuing terminal and receiving terminal, used to receive the commands issued by the command issuing terminal based on the main control chip A9101 and perform corresponding operations; receiving terminal: connected with the main control module, used for answering with wireless earphones The transmitted voice of the command terminal. The instruction issuing terminal is used to issue pairing and power adjustment instructions; the main control module receives the instructions issued by the instruction issuing terminal and performs corresponding operations; the receiving terminal is used to use the wireless earphone to answer the voice transmitted by the instruction terminal. The present invention effectively prevents the problem of co-frequency interference in the communication process, and at the same time, multiple stations coexist without tandem listening. When encountering the same frequency interference, it will automatically hop frequency to avoid it, and the communication will not be affected.

Description

technical field [0001] The invention belongs to the technical field of fixed-frequency communication information anti-jamming, and in particular relates to an anti-jamming information processing system and method based on digital frequency modulation and encryption technology. Background technique [0002] At present, the closest existing technology: the current equipment in the market is the use of fixed frequency and fixed communication mode. The coexistence of multiple stations requires manual setting of different communication frequencies. However, there are many tourist guides in the scenic spot, and the defect is that the same frequency will always appear. Listen to the question. [0003] The prior art is a point-to-point communication. As long as the frequency points are the same, information can be received. The communication has no privacy and is easy to interfere with each other. [0004] The prior art is a fixed single-item communication method, which can only be...

Problems solved by technology

[0008] To solve the above problems, it is necessary to realize the jumping screen communication, but the data is not received completely under the strong interference of the jumping screen, and the receiver needs to do a cyclic search within the entire frequency period, and there will be no sound during the search period, which also takes a long time , affecting the visitor experience
