The design of train automatic voice broadcast system based on wireless communication

Abstract Wireless communication feature is the use of electromagnetic signals can propagate in free space carried a communication way exchange of information, the advantages of wireless communication is inexpensive cost, short construction period, adaptability, scalability, and equipment maintenance on easier to implement, as a background task to expand the wireless communication research。

Based Automatic Train voice broadcast system for wireless communication is the use of single-chip wireless communication technology, research and a highly accurate broadcast system, which aims to implement voice broadcast on the train, prompting passengers and train staff on arrival, etc。 。 According to the paper introduces the basic principles of access to information as well as research and development status of wireless communications, automatic voice broadcast system needs analysis, and knowledge of broadcast hardware and software design based on knowledge and learning to the MCU voice。 According to the system design into hardware functions of the wireless communication section, the control circuit, voice processing section and a display circuit, main control chip STC89C52。 Software design should be completed according to the system functions into a wireless communication module,  main control module, voice processing module and display module design gives  the program flow chart of each module and the corresponding program code, test verification test results show that the system is properly feasible。

Key words: wireless communication control system signal acquisition voice broadcast
