Oil well pull / pressure tester is an important test of the oilfield operations equipment , its main role is to test oilfield wells pull / pressure normal judgment wells working conditions . The tester in P89C60X2 core embedded system , including pull / pressure sensors , sensor signal conditioning circuits , A / D analog-to-digital converter , LCD monitor, keyboard, data memory , Hitachi clock chip , serial interface , and printers, etc. The hardware interface circuit , signal conditioning , data acquisition , acquisition results of data or curve display , keyboard control , data storage , serial communications and data printing . The main work of this thesis is mainly manifested in the following aspects : the first on the various functions of the tester requirements analysis , put forward the the tester overall design program , divided into various functional modules ; second according to instrument design requires complete tester each circuit module hardware design ; fully consider the basis of field work to design a set of easy to operate , simple interface , powerful software system ; fourth least square method to verify the instrument error ; fifth scene prove tester software and hardware design is reasonable and feasible , and also found some design deficiencies , and put forward a number of recommendations for improvement .
