Study On Synchronous Key Technologies Of Remote-controlled Explosive System For Seismic Exploration

From the sixties of last century to the present, seismic exploration method has been used as the main way in the explosives. Practice has proved that the way has a good result Because of having sufficient energy. Why seismic waves excitation required to have sufficient strong energy? In oil exploration, the seismic reflection method to use to identify the scope of a depth of several kilometers under the ground floor, the spread to return to the ground floor of the ground. The wave must be dismissed in such a long distance, if there is not enough energy. In addition, with the effective wave excitation at the same time there are various types of waves, such as the interference wave, abnormalities wave. Therefore, the earthquake wave should have sufficient energy, .Synchronous system of remote-controlled explosive machines (referred to as remote-controlled explosive machine) is one of the major seismic exploration equipment. With the development of geophysical seismic exploration technology, the equipment has a great improve. At the same time, the improve meet the needs of the market as the goal. The direction of modern seismic exploration is digital, high-precision and high-density, but also towards large-area multi-dimensional exploration, network exploration, high efficiency and low-cost exploration and development.Synchronous system is provided by two parts: the encoder and decoder. Encoder installed in the seismic equipment, on board, shot is the decoder. In seismic data acquisition, the encoder output clock TB signal to control .decoder control the excitation source in order to achieve seismograph excitation source acquisition and synchronization.In this paper, a thorough study in the same equipment at home and abroad based on the design with 51 single-chip embedded systems as the core and is equipped with serial communication modules, the keyboard and LCD display and flash memory; software including communications, voltage detector , delay time testing, and other modules. Research in the following areas:1. Theory research: To study the source synchronous system, the key technologies, of the delay, synchronous compensation technology, depth correction technique, and basic knowledge of radio modules.2. System production: C8051F-based microcontrollers as the core of the control system hardware, including CPU, level conversion, display, keyboard , the battery voltage detection, communication detection 3. To prepare a set of easy to use, powerful software system.In short, the field test results show that the logging system of hardware and software design are feasible。This thesis includes seven chapters:Chapter 1 ,Firstly, introduces the theory of remote-controlled explosive system, Secondly, it analyzes the development of remote-controlled explosive system, finally gives the content and meaning of the paper.Chapter 2: Study on synchronous key technologies of remote-controlled explosive systemChapter 3 is the design of the c8051 as the base of the system.Chapter 4 is the design of the mainly computer software.Chapter 5: mainly about a lot of indoor tests for the self-detectionChapter 6: the conclusion of this paper summarizes the research and look forward to the future work.
