A System Of Telemetering Dynamic Parameter For Racing Boat

With the development of our country's aquatic tournament, the racing boat training devices Nowadays can not meet the requirement of scientific trainings. In order to pursue the racing boat training and to satisfy the demands of the informational construction in physical training, a racing boat telemetering training system is introduced and designed in this article, which is based on wireless communication and data disposing via singlechip. In the system, the acceleration sensor will create analog signals with working condition of the racing boat. Next, by A/D conversion, the signals are converted into PWM digital signals, which are processed by the singlechip to get precise acceleration values. Then the acceleration value is transmitted by wireless communication module and received by the receiver, and inputted into the computer via RS-232 serial port, the computer can deal with multi-data and make output, storage and image displaying, etc. The method overcomes shortcomings of traditional racing boat training devices, which can not store athletes' score and can not get competition information in real time. The new equipment can store and transmit data automatically, display the present information and access the results. The system can also be applied to many kinds of boats including some onshore equipments to measure the speed.The dissertion introduces this system in three parts: hardware design, communication protocol and software design. Firstly, it introduces the choice and design of the hardware, which includes LAMD2002A sensor, the ultra low power singlechip P89LPC935, wireless digital module SRWF-108, subsidiary spare parts, etc. Secondly, the communication protocol is discussed, which this system uses, it covers frame structure, name, communication course, etc. Then the software design is provided, which includes singlechip software design and PC software design. Finally, a conclusion is drawn on the basis of many practical experiments. And practice has proved that the design is available and useful.
