The Research Of Remote Supervise And Control System Based On TCP/IP And Database Technique

This subject had done some research in remote supervise and controlsystem based on TCP/IP protocol and database technology. By applyingthose technologies to High Frequency Fatigue Experiment Machine, thissystem realized remote control of High Frequency Fatigue ExperimentMachine and data communication between PC and MCU. The researchwork of the dissertation include mainly as follows:1. After investigating the mechanism of network supervise and controland structure of remote control system, the subject build the remote controlsystem based on C/S, in which the characters of B/S & C/S structure willbe analyzed in detail. Then, the paper adopted the TCP/IP networkcommunication protocol, which based on the actual require of the system.2. The subject inquired into the key technique of remote control——Winsock program in detail firstly, after which it analyzed mechanism andrealization of network communication in Winsock, then selected thecorresponding mode for communication, after all the subject introduced theinterface function of network communication in Winsock. 3. After raising the general design scheme for remote control system,the subject realize the communication between MCU and Server byadopting MSComm Control provided by Visual C. The subject divided thewhole software into several functional modules, in which SQL2000 wasadopted as the database for remote control system and ADO technique wasapplied to access to the database. Researched and Analyzed the questionsof the real-time character and safe character of the system.4. The subject fulfilled the debugging work of whole system. The resultproved that it realized management of the experiment data, in whichaccessing to the database, inquiring of waveform data/historical data andcalling the experiment result are feasible.
