Research And Realization Of Teletypewriter Training System On Visual C++

In teletypewriter training subject, the author noticed that the number of the students is much more than that of the machines, which leads to several people sharing one machine and delaying the training progress and results, thus the author decided to study the teletypewriter exercise system.The paper describes the study of teletypewriter exercise system devised and developed with VC++ technology. The whole system consists of five parts, including soldier teletypewriter training system, soldier information managing system, soldier result managing system, sending code and receivingcode by inserial communication, and testing algorithm of CRC(Cyclic Redundncy Check). The research's main direction is to improve the makings of the operator through telex training, and touches upon CRC( Cyclic Redundncy Check) arithmetic.The system takes adopted teletypewriter 1000 some functions, and some relevant knowledge about teletypewriter 1000 is introduced, which lay the theoretical foundation for the system design. According to teletypewriter 1000 parameters in common use, the system establishes five training stages to carry on the training, the system can simulate teletypewritera's some characteristics in the function. When the training is over, the results are available for check to provide basis for training adjustments. The system can manage to the soldier's information and the results by the adding, the deleting, the modifying function. The system is featured by some qualities, that is , first, HOOK arithmetic is applied so keyboard can give out the sound of code; second, SDK arithmetic can read out the codes; third, some functions devided by the system is not possessed by the teletypewriter 1000.As a result, the system the fulfillment of the design purpose and the improvement of the training results are both attainable.
