The Analysis And Realization Of Serial Communications Of Survey And Control Techniques Based On Computer

The thesis discussed the method and pratical realization of the serial communication under survey and control's function based on computer.The working principle of serial communication of the international survey and control system and introduction of the client/server model of survey and control techniques of computer systematical analyse the method application of serial communication in the survey and control's system on base the hardware of system and software of serial communication which is studied carefully,abundant used the techniques of serial communication of survey and control which is medium in computer and core in internation. Enumerate the fudamental element of system,e.s the instrument of survey and control,model of survey and controland computer,wherea connected the fundamental element into an unite system,in which used the international communication to connect the system into one unity.And used the MSComm control element and PCI panel on the hardware fundamental to make the design of software.In the hardware design of survey and control system,which used the serial communication standard RS-232C and some instrument of PC,model of survey and control,to make the C/S(client/server) into pratice,and introduce the related instrument of hardware,and used the central computer controler to practice the control in field.It has used the function of international communication in design and fundament element(e.s computer,instrument of survey and control system to connect into unity with internation,then make into a survey and control system. This thinking for which connected the survey and control system and internation of computer to make the gathering,transmission,management and handlement of information into the synthesize communication system,it has the requirement of developed communication and thinking of characteristical in communication age.It has used the Visual Basic 6.0 to complete the software in design,and used the control elements of MSComm and the ActiveDAQ of Yanhua company to complete the communication in serial.This thesis connected the software and hardware into one perfect unity,but make the techniques of survey and control,computer,communication into one communication of survey and control system in ingenious,so that complete the mission in design.
