The thesis contains five chapters. The first chapter summarizes the development and research of switched reluctance drive, discusses the main research direction, and explains the main work in this paper. In chapter 2, hardware system which includes the design of power converter and various control circuit is discussed. TMS320LF2407 DSP is used to design the hardware circuits of SRM control system, and design details including the current detection, position sensing, fault protection, speed detecting, keyboard and display etc. are provided. Because of the full use of the abundant peripheral resources of DSP, it comes to the aim simplifying the circuit structure and heightening the reliability. In chapter 3, the application of neural network on SRM control system is introduced, a new the application of neural network and the method of sampling is proposed and a simulation system based on Matlab/Simulink is established. Chapter 4 discusses the routine designing issue. Because the modularized programming method is adopted, and multi-interrupt processing technique is used, operation efficiency of the control software is highly raised. At last, the foregoing SRM control system is tested. Speed adjustment is realized, and other targets on the research and design of SRM control system are reached, which establishes a good foundation for further research.

To be able to grasp more opportunities for sex crimes at the same time the relatively high use of three-station configuration, to operate a computer, here are divided into A Computer, B Computer and C computers, computer A computer-based operations, the main task is to buy and sell orders operations and holdings of individual stocks that have been tracked so that the best point and fled the country, late in the day or night, werewolves are the technical stock selection, with the potential to become a dark horse, or it is possible to start the second Stock elected, put into the C computer Optional Share Lane, B computer is a laptop, while wirelessly with a broadband connection, broadband and sometimes dropped to avoid or segment of electricity causes can not be traded, the general cases, the task of the computer B is always concerned about the A shares and Hong Kong stock market trend in broader market, in the opening period of time, C is Optional Share computer display, and interface options with the four shares of K-line column, and set to automatically turn the industry, so that If the C Optional Share computer technology, there are individual stocks will soon reach the selling points, werewolves can be found in the first time and simultaneously enter the code in the A computer, using keyboard shortcuts with the fastest speed for the next single!

为了能够把握更多的机会，狼人同时运用3台配置相对较高的电脑进行操作，这里分为A电脑、B电脑和C电脑，其中A电脑为主操作电脑，主要任务就是进行买卖下单操作和对已经持有的个股进行跟踪，以便在最佳点位出逃，在每天的盘后或者是晚上，狼人都会进行技术选股，把有可能成为黑马或者是有可能二次启动的股票选出，放入到C电脑的自选股里，B电脑是笔记本，同时以无线方式与宽带连接，避免了有时宽带掉线或者是段电的原因造成无法进行交易，一般情况下B电脑的任务是随时关注A股大盘和港股大盘走势，在开盘的时间内， C电脑显示为自选股，同时界面上选择4股K线同列，并设置为自动翻业，这样，如果在C电脑的自选股中有个股即将到达技术买点，狼人可以在第一时间发现并同时在A电脑中输入代码，使用键盘快捷方式以最快速度进行下单！

It carries on the real-time examination to bicycle's speed whichused the examination and transformation technology, microcomputercontrol and connection technology and digital circuit technology.And the installment will compare the measurable speed with the safespeed which is input by the keyboard. If the measurable speed isfaster than the restricted speed, it will actuate the buzzer towarn.
