| The well drilling parameter measuring appliance is the well drillingproject monitor well drilling process,carries on the scientific analysis and themacro-scientific policy-making important tool. In had understood the presentdevelopment situation of the domestic and foreign drilling machinesparameter monitors foundation, the thesis designed the survey plan of thevehicle to carry the drilling machine parameter to monitor, which causes tosneak in the condition to the drilling machine to carry on the real time displayinto to be possible. The hardware are partial mainly by micro controllerMSP430F449, various sensors,changes delivering,the filter enlarges theelectric circuit,the power circuit, the display circuit and so on partially iscomposed. Several groups sensors signals have the simulated signal and thedigital signal two kinds, and the simulated signal after enlarges the electriccircuit to enlarge directly connects to MSP430 singlechip internal A/D part tocarry on the simulated conversion, after the digital signal transmitted light paircomponent isolation sends in the MSP430 singlechip directly to preserve, inorder to transfers at any moment as necessary to carry on processing. Thesoftware part is under the IAR Embedded Workbench software platform andusing the VC++ language establishment software, which can convenientlyenter the CSPY debugging environment, and can use PC machine and theJTAG debugger carries on the on-line debugging development, finally hasproduced the software flow chart. This research "the drilling machine parameter instrumentation" unifiesthe request of the construction institute "the automobile sneaks in thesystem", carries on the examination to well drilling process's many parametersof the project well drilling, and this system already passed the correlationdepartment's appraisal, conforms to the design requirement, and alreadyinvested into the practical application, and has obtained the good applicationeffect, and had the good promoted application prospect.
