The Design And Implementation Of Seismic Data Acquisition Transmission Controlling System

With the development of the seismic prospecting technology and the increase of seismic prospecting request, and because of the development of electronics and communication technology, the seismic prospecting equipment has changed from analog recording equipment to digital network equipment. Nowadays, the popular seismic prospecting equipment with 24 bit Sigma-Delta ADC technology fits the high resolution request, developing a equipment which is flexible, convenient and stabile for tasks is necessary because of the change of the seismic prospecting request. According to the actual application request, this research is aimed to design a data acquisition transmission controlling system to realize the small signal seismic data acquisition, storage and transmission.According to the application request of the system, this thesis gives the primary function goals and the whole design scheme, including data acquisition transmission controlling system, long-distance monitor system and the wireless transmission design scheme. Then choose the proper chip of each function part according to the functional request analysis. In terms of hardware design, gives the C8051F020 MCU resource design scheme, the primary function circuit design including data acquisition, GPS timing, data storage and so on, and PCB design. In terms of software design, introduces IDE, gives the software structure and the primary function block software design such as data acquisition, GPS timing, wireless communication and so on. At last, does testing work on the hardware and software functions, then gives the testing results and improvement suggestions.The results of the experiment show that the primary functions of the data acquisition transmission controlling system work well and the equipment is going to be used for actual measure task.
