Study On Some Techniques Of Seismic Exploration Safety Detection

The prospecting equipment's status of an oil field is the reflection of its exploring level. The current terrestrial seismic exploration in China mostly adopts the dynamite's exploding inside a well. And the main shortcoming of the dynamite as the hypocenter is that it is unsafe. So it is significant to develop the seismic exploring safety detection equipment with automatic ignition. China is just in the beginning of making such scientific researches.From the point of view of the un-touching metering, this paper introduced the problem that we confronted in the safety detection during seismic exploration, analyzed measurement of the safety distance between the operator and the hypocenter, then provided some solutions according to a certain application such as environment changed.Firstly, the paper carefully introduced the information fusion technology, which was easy to be realized and applied currently, then researched its details. The information fusion technology makes up the deficiency of single sensor to measure the distance. Synthesizing information from multi-sensor can make instrument acquire more perfect and more comprehensive information about measured object and make proper decision. Secondly, the paper introduced how to implement safety detection by ultrasonic sensor, and presented systemically all the design of collecting and processing signals, storage circuit, lithium battery charging and discharging circuit, data communication circuit, keypads and LCD. This paper studied the code of uC/OS-II and introduced how to port uC/OS-II onto LPC2214. The Real-Time Kernel uC/OS-II is a highly portable, ROMable, very scalable, preemptive real-time, multitasking kernel (RTOS) for microprocessors and microcontroller. Also introduced how to program in the multitasking environment and how to classify and define each task and then provided some data of field-experiment. Finally, this paper did some research on the millimeter wave radar ranging and provided some realization scheme and such detailed description.
