Anti-interference 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-interference, and discloses an anti-interference information processing system and method based on a digital frequency modulation and encryption technology, and the system comprises an instruction issuing terminal which is connected with a main control module and is used for issuing a pairing and power adjustment instruction; the main control module is connected with the instruction issuing terminal and the receiving terminal, and is used for receiving the instruction issued by the instruction issuing terminal basedon the main control chip A9101 and executing corresponding operation; and the receiving terminal is connected with the main control module and is used for answering the voice transmitted by the instruction terminal by using the wireless earphone. The instruction issuing terminal is used for issuing pairing and power adjusting instructions; the main control module receives an instruction issued bythe instruction issuing terminal and executes a corresponding operation; and the receiving terminal is used for answering the voice transmitted by the instruction terminal by using the wireless earphone. According to the invention, the problem of same-frequency interference in the communication process is effectively prevented, channel crossing listening does not occur in coexistence of multipledevices, automatic frequency hopping avoidance can be realized in case of same-frequency interference, and communication is not affected.

Description

technical field [0001] The invention belongs to the technical field of anti-jamming of fixed-frequency communication information, in particular 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, Zhilian WUS interpreter, adopts a fixed-frequency communication mode, and the coexistence of multiple sets requires manual setting of different communication frequencies. However, there are many tour guides in scenic spots, and the defect is that there will always be the same frequency. Listening questions. [0003] The existing technology 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 it is easy to interfere with each other. [0004] The prior art is a fixed single-item communication mode, which can ...

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
