The networking and data transmission mode of the field mobile seismic station involves such matters as richness, real-time and effectiveness of seismic data. In this paper, we propose a networking and data transmission mode with CAN bus and embedded technology. In light of the effectiveness, distance, cost and construction relating to data transmission in the field environment, CAN bus was utilized to connect the scattered seismic collection nodes, and the embedded microprocessor ARM was used to manage collection nodes within a certain scope. In addition, both the multiple task operating system Linux and application framework Qt were employed to construct a seismic network local management system, which significantly simplified the management task of mobile station. Such networking and data transmission mode shows such features as lower cost, easy construction, and higher reliability and instantaneity, also enables the possibility of constructing a mobile collection station with larger scale.

A Networking and Data Transmission Mode of Mobile Seismic Station

With the development of computer technology,communication technology,network technology and control technology,field bus technology and PLC communication technology is gradually mature,and plays an important role in the industrial production.As a new technology,field bus technology is also called the multi point communication,digital and open bottom control network,and mainly applied in the measurement and control device between a bidirectional serial multi-node digital communication system as well as the industrial production site.A PLC network communication scheme based on CAN bus is proposed,and this scheme,by configuring PC and each PLC respectively with a RS232-CAN gateway,makes PC and PLC of CAN bus communication ability,thus constructing the CAN bus-based PLC communication network.
