| In order to obtain more abundant information of geoelectric field , the method of traditional point-by-point measurement electrical survey can't meet actual demand . But the high density electrical survey which has been developing in recent years has been high up in the picture on the issue of engineering geophysics etc . In this paper , the software for array geoelectric field recording geometry based on 1-Wire protocol and the hardware correlated with the software are explained . Since 1-Wire technology is the key of the paper , a majority of the paper are used to show the following three ideas : the interface between 1-Wire chip and micro-processor , 1-Wire protocol and 1-Wire instructions . Then the structure of the intelligent electrode grounded on 1-Wire technology and the intelligent control for Multi-electrodes change System composed by intelligent electrode are discussed . On the other hand , the software design philosophy of top-down modularization has been adopted in the dissertation . The control software which is convenient in man machine conversation , advantageous for interface , high performance and reliable, full-scale in function has been skillfully built by reciprocally transferring between highlevel language and assemble language of Single Chip Micyoco . Furthermore , the dependable hardware connection which provides a dependable platform is an important basal item in the course of the system's research . It has been proved that the Multi-electrodes geoelectric field data acquisition system based 1-Wire technology is not only right on design thought , but also practicable on technical method according to the result of systemic jointly debugging of software and hardware , modeling test and physical analogue in the flume. To sum up , the research effort has been basically gain its anticipated ends . At the same time , it can be concluded that 1-wire technology be widely applied on the instrument research of array electrical survey in future . |
