| The subject involves in some important problems and present situation that exist in parameters monitoring in oil well drilling. An application system is designed to monitor the parameters in real time in this paper. The paper emphasizes VO characteristic of THE PROBE sensor and syntonic sensor and H2S concentration sensor based on analyzing the working principle of many kinds of sensors. Then the types of upper sensors are determined. The CMOS chip AT89C2051 is used in this system because there is only a small quantity of program to be stored. This system uses wireless transmission module D21DL to form the network of wireless transmission. In this way, such disadvantages as low removability and expansibility and longtime construction are avoided. Digital filtering method is applied to improve anti-jamming performance. At the same time, check sum is sent and communication protocol is established to keep error data out and multi-period measuring method is taken to improve measuring precision. Affective anti-jamming measures are given after all-sided analysis on potential interference. Administrant efficiency can be improved greatly and workload of managers can be cut down and incident of safety can be reduced to a certain extent when the system is applied. In a word, this system is an effective choice for oil group to consummate management that has certain practicability and high social generalization value.
