The Cabin Alarm And Safe Mobilization Systems, Relaying On The Wireless Radio Frequency

As the development of the Wireless Telecommunication, the field, in which the Wireless Data Transmission is used, has enlarged. The monitor system that based on radio frequency, shows an example that the Wireless Data Transmission is used in the fields of Wireless Telecommunication and Automation Program control. This thesis, based on cabin monitor, develops the cabin alarm and safe Mobilization systems, relaying on the wireless radio frequency.This thesis introduces the design of the hardware module of the Wireless Data Transmission plate, and the accomplishment of its functions. The monitor terminal has small volume, low cost and reliable motion. The major aspects of this subject: (1) the choice of bus master and the accomplishment of its functions. The AT89C51 is chosen as the bus master, the major functions of the 89C51 are studied, in order to accomplish the control to the data Transmission of wireless radio frequency module. (2) The design and accomplishment of the radio frequency module. It uses the nRF401 radio frequency chips of Nordic company, and accomplishes the Wireless Data Transmission in short distance by the global interchangeable ISM channel. (3) The design of the agreements and proofreading in the Wireless Data Transmission. This thesis designs the agreements of data Transmission, which is in subordination for single chip, and also designs the methods of proofreading. The high reliability of data transmission is ensured, and the Anti-Jamming Technique of this system is improved by CRC and Hamming code. (4) The design of Human-Machine Interface.The research in this thesis finds efficient method to alarm in time, when the accidents in cabin working happen, and to solve the problem of shipping control. The fact shows that the designed terminal is with reliability, can meet the needs of design and cabin monitor. The cabin alarm system and safe control system can be used widely in the aspects of brainpower control, wireless data transmission monitor, and so on, with broad development.
