Client/Server-Based Remote Control Research And Design For Three-Tank Water Control System

Remote control experiment system is an important application of computer communication technology in the technology of control; it takes good advantage of the limited resource into full use which is with extensive foreground. The article designs a primary remote experimental system of Three-tank water control system and realizes it. The hardware of the system is composed of remote control computer, internet, computer, host computer and three-tank water control system, etc; the software is composed of remote control software and local control program.The article first introduces the research background and significance of remote control experimental system, and it identifies its main researching task combined with the technology's state of development and application home and abroad. Then, the article proposes that the three-tank water long-distance control system should adopt C/S mode after comparing and analyzing the C/S and B/S mode. Next the author describes the feature of Winsocket based upon TCP/IP Protocol, and indicates that the byte stream socket which suits for disposing large amounts of data is the main network programming interface for the system to program the network long-distance control software.The system is based on Vc++6.0 software, and it makes use of Winsocket to accomplish the communicator design of the client and the control server, and it realizes the three-tank water remote control system based on the C/S structure. The client mainly functions as user's logging on, experiment bespoke, sending order to server, parameter setting, sending and receiving the data from the server and graphic displaying, etc; while the server mainly functions as instruction receiving, data real-time control, the realization of control algorithm, etc. The system uses SQL Server2000 as the managing software of data base, visits the data base with VC, and connects the database with ADO technology.The article makes a clear explanation to the process of the software design and the method of the control system. It goes through many times of experimenting, program debugging and modifying and it accomplishes the three-tank water remote control system and realizes the expectant outcome. The experiment proves the effectiveness of the project, and points out the ways in which the system should improve in the future.
